Abstract
A connector includes a housing having a bore with a housing groove disposed on an inside surface of the bore with a groove establishing a release angle between a housing groove bottom and a bore inside surface. A retainer defines a spring cavity between a retainer and the release angle and a circular radial canted coil spring is disposed in the spring cavity. A pin having a tapered end and a body diameter sized for sliding engagement with the bore is provided which includes a circumferential groove in the pin body for receiving the coil spring upon insertion of the pin into the bore. A circumferential groove includes a load angle for rotating the coil spring in an orientation in which the major spring axis is parallel to the release angle upon initial withdrawal of the pin from the bore. The coil is further compressed along the spring minor axis and expands radially upon continued withdrawal of the pin from the bore.
Description
- The present invention is generally related to connecting mechanisms and is more particularly related to a connector that requires low force to connect and high force to disconnect.
- Connectors have been used in a great variety of applications, see, for example, U.S. Pat. Nos. 4,678,210, 4,763,683, 5,411,348 and 5,545,842. Each of the connectors referenced are directed to specific applications.
- For example, U.S. Pat. No. 4,678,210, provides for a loading and locking mechanism directed to engaging and interlocking lightweight, delicate and many times fragile cylindrical parts with one another and provides for locking means for preventing separation of a first and second cylindrical member.
- U.S. Pat. No. 4,763,683 is directed to a breakaway coupling for a coaxial fuel supply hose and provides for inner-connecting valve bodies, which define a center fuel supply passage.
- U.S. Pat. Nos. 5,411,348 and 5,545,842 are directed to mechanisms for connecting and locking parts for effecting electromagnetic shielding, electrical conductivity, heat dissipation and environmental sealing.
- The present invention provides for a connector utilizing a radial canted coil spring positioned within a housing groove in a manner for controlling connect and disconnect forces with a groove pin.
- A connector in accordance with the present invention generally includes a housing having a bore with a groove disposed on an inside surface of the bore. The bore groove establishes a release angle between a housing groove bottom and the bore inside surface.
- A retainer is provided for defining a spring cavity between the retainer and the release angle and a circular radial canted coil spring is disposed in the spring cavity. The coil spring includes a centerline, a major and a minor axis, as hereinafter described.
- A pin is provided having a tapered end and a body diameter sized for sliding engagement with the bore inside surface. A circumferential groove is formed in the pin body for receiving the coil spring upon insertion of the pin into the bore.
- The circumferential groove includes a load angle for rotating the coil spring in an orientation in which the spring major axis is parallel with the release angle upon initial withdrawal of the pin from the bore. Continued withdrawal compresses the coil spring along the spring minor axis and upon further withdrawal of the pin from the bore the spring expands radially.
- More particularly, the load angle is disposed below a centerline of the coil spring, should the load angle be above the centerline of the coil spring, disconnect would not be possible. This distinguishes the present invention from the hereinabove referenced prior art patents.
- More particularly, the housing groove may include a coil groove stop disposed between the release angle and the bore inside surface for limiting axial movement of the coil spring upon withdrawal of the pin from the bore.
- The release angle may be disposed at between about 5° and about 90° to the centerline connector and is preferably disposed at between about 25° and about 65° to the connector centerline.
- With the use of the stop means, hereinabove noted, the preferable release angle is between about 25° and about 30° to a centerline of the connector.
- Still more particularly, the coil spring may be initially disposed within the cavity with a major axis disposed within an included angle of between about 30° and about 45°. In that regard, the coil spring may be initially disposed in the cavity in a convex orientation or in a concave orientation.
- In all of the embodiments of the present invention, the load angle may be disposed at an angle of between about 5° and about 90° with the connector centerline and preferably at about 40° to the connector centerline.
- Preferably, the coil spring has an inside diameter smaller than the pin body diameter, so that a force is provided which urges the coil spring toward the inside diameter of the pin groove. This facilitates insertion of the pin into the spring. In addition, preferably, the load angle means is greater than the release angle by at least 1°.
- Further, control of the ratio of connect to disconnect forces is provided by a spring having a ratio of coil width to coil height of between about 1 to about 1.5, preferably, between about 1 to about 1.04.
- The advantages and features of the present invention will be better understood by the following description when considered in conjunction with the accompanying drawings in which:

- With reference to FIG. 1, there is shown a connector10, which includes a
housing 12 having abore 14, having agroove 16 disposed on an inside surface 18. Thegroove 16 establishes a release angle, or surface, 22 between ahousing groove bottom 24 and the bore inside surface 18. - A
retainer 28 is provided, which defines aspring cavity 30 between theretainer 28 and therelease angle surface 22. - A circular radial canted
coil spring 32 is disposed in thespring cavity 30 and apin 34 having atapered end 36 includes a body 38 having a diameter sized for sliding engagement with the bore inside surface 18. - The
pin 34 includes acircumferential pin groove 48 having a load angle, or surface, 46, which provides a means for rotating thespring 32 to an orientation in which a springmajor axis 54, see FIGS. 2 and 3, is parallel with therelease angle 22 upon initial withdrawal of thepin 34 from thebore 14, as will be hereinafter discussed in greater detail. - Further withdrawal of the
pin 34 from thebore 14 compresses thecoil spring 32 along a spring minor axis 56 (again, see FIGS. 2-3) and expands thespring 32 radially upon continued withdrawal of thepin 34 from thebore 14 as also discussed hereinafter. - With specific referenced to FIGS. 2 and 3, there is shown the circular radial canted
coil spring 32 having acenterline 60 and a turn angle A. The turn angle A is the angle between thecenterline 60 of thespring 32 and a centerline of thecoils 62.Such springs 32 are described in U.S. Pat. Nos. 5,139,243, 5,108,076 and 4,893,795. These patents are to be incorporated herewith in their entirety by this specific reference thereto for describing the types of radial springs suitable for the present invention. - This
spring 32 includes an inside diameter, D, which is smaller than thepin groove 48 diameter in order that thespring 32 is forced toward a pin groove bottom, or inside diameter, 66. - As shown in FIGS. 1 and 4-8, the
release angle 22 is disposed at about 23° to a centerline 70 of the connector 10. It should be appreciate that this release angle may be disposed at between about 5° and 90° with the centerline 70 of the connector 10 in order to control, connect and disconnect forces, as hereinafter described. - With reference again to FIG. 1, the load angle, L, may be disposed at an angle of between about 5° and about 90° to the connector centerline70, with about 40° being shown in FIGS. 1-8. This load angle surface contributes to the control of connects/release force ratios, as will be hereinafter discussed in greater detail.
- As shown in FIG. 9, a
radial spring 72 may be initially disposed in thecavity 30 in a concave orientation with an included angle of between about 30° and about 45°, 30° being shown. In this arrangement, a major axis 76 is initially oriented in a direction toward a connect direction of thepin 34, as shown by thearrow 78. - With reference to FIG. 10, there is shown a
spring 82 disposed in a convex orientation within thecavity 30 having an included angle of between about 30° and about 45°, 30° being shown. In this arrangement, a coilmajor axis 84 is oriented against an insertion direction of thepin 34, as indicated by the arrow 86. It should be appreciated that common reference numbers used throughout the specification and all of the drawings represent identical or substantially similar components. - FIGS.11-16 are similar to FIGS. 1 and 4-8 with a release angle of about 33°. Similarly, FIGS. 17-22 include a release angle at 33° utilizing the
concave spring 72 and FIGS. 23-28 represent sequential connect and disconnect steps utilizing aconvex spring 82 with a release angle of about 33°. - FIGS.29-34 are similar to FIGS. 1 and 4-8 with a release angle at 45°. FIG. 35 is similar to FIG. 29 utilizing a
concave spring 72 and FIG. 36 utilizing theconvex spring 82 sequential connect/disconnect steps are represented in FIGS. 30-34. - FIGS. 37 and 38 are similar to FIG. 1, with a release angle of 65° with a corresponding
concave spring 72 andconvex spring 82 being shown in FIGS. 39 and 40. - FIGS.41-45 shows the
convex spring 82 with sequential connect and disconnect steps with a release angle of 65°. - Variation of the
load angle 46 to therelease angle 22 affects the force required to disconnect. The larger therelease angle 22, the higher the force to disconnect. The larger theload angle 46 the greater the force required to disconnect. The greater therelease angle 22 the greater the coiled 62 reflection and the greater the force required to disconnect. - As hereinabove noted, the closer the radial centerline70 of the
spring 32 to aload point 90 at the intersection of the pin body 38 with the load angle surface 46 (see FIGS. 1) the higher the disconnect force preparing in mind. However, if theload point 90 is above the centerline 70 disconnect is not possible. - As shown in FIG. 1, the
radial spring 32 has a 0° turn angle that is a major axis 94 (see FIG. 1) is parallel with the connector centerline 70. The concave springs 72 have an included angle of between 1° and 89° included angle and theconvex spring 82 has a turn angle of between about 1° and 89° included angle, with 30° being shown in the FIGS. 17-22 and 23-28 respectively. - Concave springs72 have the advantage of reduced force during initial connection when the concave angle is the same as the entry angle B, see FIGS. 1 and 9 of the
pin 34 because minimum force is require to turn thespring 72 during connection. If the angles of thesprings tapered end 36 of thepin 34 must turn thespring major axis tapered end 36 of thepin 34. The higher the variation that exists between the entry angle B of thetapered end 32 of thepin 34 and the turn angle of the spring the higher the force will be required to connect. - As shown in FIGS. 1 and 4-8, the
radial spring 32 has amajor axis 94, which is parallel to thecenterline 70, 60 of thespring 32, see FIGS. 2-3. This type ofspring 32 is desirable when thepin 34 has no chamfer, or tapered end, not shown. - In this case, the
pin 32 outside diameter at entry will be parallel to the major axis of coil since the inside diameter of thespring 32 is generally smaller than the pin body outside diameter 38. A tapered end, or chamfer, 36 is desirable for facilitating assembly. Thetapered end 36 reduces the force required to connect, which is important since an objective of the present invention is to maximize the ratio of disconnect to connect force. - The
concave spring 72 has the advantage that thetapered end 36 of thepin 34 at the entry angle can be made parallel to the concave angle. In this manner, the initial force required to connect is minimized by making the spring concave angle the same as thetapered end 36. - The
convex spring 82 requires substantially greater force at entry because it will be necessary to turn thisspring 82 to the position of the entry angle of thetapered end 36 of thepin 34. Thus, theconvex spring 82 is desirable and applications for a high entry force is desirable. - When connection takes place, the
spring pin groove 48. The force required to disconnect the connector 10 varies depending upon the type ofspring concave spring 72 requiring more force to disconnect than theradial spring 32 andconvex spring 82. The reason for this force difference is due to the fact that thespring major axis release angle surface 22 in thehousing 12, and that requires turning of thespring - The
concave spring 72 requires greater degree of turning of the coil in theconvex spring 82 and the more turning thespring spring concave spring 72 offers greater variation between disconnect and connect ratio because it requires less force to connect and greater forces to disconnect. When this feature is desirable toconcave spring 72 has significant advantage. - In general, there are four main factors that effect the selection of the spring for maximum connect or disconnect ratio. They are:
- 1. A connector whose entry angle is parallel to the entry angle of the spring.
- 2. A coil that when deflected radially during the connecting process has the minimum amount of frictional force. A concave spring will have less frictional force.
- 3. A spring that when it is in the connect position will assume a turn angle that will require maximum turning, thus creating greater stresses on the spring and upon deflecting the disconnect will create a higher force.
- 4. A spring when deflected at disconnect will develop a higher force by varying the release angle. The higher the release angle, the higher the amount of spring deflection and the higher the force developed at disconnect.
- In addition to the type of spring used, the many factors that will affect the disconnect force.
- 1. The larger the release angle of the housing, the greater the force required to disconnect.
- 2. The larger the load angle, the greater the force required to disconnect.
- 3. The larger wire diameter of the spring coil, the greater the force developed and the higher the force required to disconnect.
- 4. The smaller the ratio of the coil width to the coil height, the rounder the cross section of the coil will be and the higher the force to disconnect. The typical desirable ratio to develop higher force would be 1 to 1.04.
- 5. The smaller the back angle of the coil, the higher the force required to disconnect.
- 6. The smaller the front angle of the coil, the higher the force required to disconnect.
- 7. The relationship between the centerline of the spring coil in a connect position to the diameter of the pin at the load point. The shorter the radial distance between the centerline of the coil and the load point, the greater the axial force developed at disconnect and the greater the force required to disconnect.
- 8. The higher the modulus of elasticity of the wire, the higher the force to disconnect. Therefore, the selection of the spring material becomes a very important factor in maximizing the ratio of disconnect to connect.
- 9. The relationship between the load angle and the release angle. The load angle must always be larger than the release angle. The smaller the difference between the two, the greater the force required to disconnect. For most applications, a variation between the two of 7° appears to work satisfactorily.
- 10. The force required to stretch the spring during connection. The higher the force, the lower the ratio of disconnect to connect.
- 11. For this type of application, a spring force that increases with deflection is highly desirable. This characteristic can be achieved in a canted coil spring by controlling the ratio of the coil height to wire diameter. The smaller the ratio, the higher the force as a function of spring deflection.
- With the present invention, the ratio of disconnect force to connect force may be as high as 30 to 1. FIGS. 1 and 4-8 illustrate sequential position of the
pin 34 andhousing 12 utilizing arelease angle 22 of the 23°. FIGS. 11-16 illustrate the connect disconnect steps utilizing a release angle of 33° and FIGS. 29-34 show the connect/disconnect steps with a release angle at 45°. These figures show a comparison between the effect that therelease angle 22 has on the axial play and deflection of thespring 32. As hereinabove noted, the smaller therelease angle 22 the lower the force developed. The larger therelease angle 22 the higher the deflection and the higher the force developed to disconnect. - It should be appreciate that the actual play of the
pin 34 varies with therelease angle 22. By way of specific example, at small angles, that is 23° and 33° the axial play is approximately the same at about 0.007 inches. As arelease angle 22 increases to 45° the axial play decreases to 0.004 inches with the same dimensions. See FIGS. 29-36. The axial deflection is 0. All of thesprings - Although there has been hereinabove described a specific connector with radial spring in accordance with the present invention for the purpose of illustrating the manner in which the invention may be used to advantage, it should be appreciated that the invention is not limited thereto. That is, the present invention may suitably comprise, consist of, or consist essentially of the recited elements. Further, the invention illustratively disclosed herein suitably may be practiced in the absence of any element, which is not specifically disclose herein. Accordingly, any and all modifications, variations or equivalent arrangements which may occur to those skilled in the art, should be considered to be within the scope of the present invention as defined in the appended claims.
