With reference to figure 1, existing (LC type) joints of optical fibre 100 have the external form of rectangle haply, and its cross section is a square.The outside surface of connector 100 is provided with rubber-like door bolt 120, door bolt 120 forms one with the shell body of connector 100, its bottom has the hinge 125 of a meeting activity, can allow lug (tab) 126 move up and down perpendicular to the central axis 150-150 of connector.In addition, sleeve pipe (ferrule) 140 is stretched out by the opening 110 of two-piece type composition, and this two-piece type composition comprises housing 110 and lid 130, and both link together by the ultrasonic fusing mode.The inside of this two-piece type composition also comprises spring (figure does not show), can make sleeve pipe 140 pass opening 111 front and back and move back and forth.Door bolt 120 comprises a pair of projection 121, and this is positioned at the relative both sides of lug 126 to projection 121.
Referring to figs. 2 to Fig. 5, duplexing type fiber adapter 200 of the present invention comprises the body 205 and the cover plate 300 of integrally formed model.In a preferred embodiment, body 205 is centered on by top sidewall 210, bottom sidewall 211, right sidewall 212 and left side sidewall 213 and defines.Body 205 inside have axial cavity, and this axial cavity is by being parallel to right sidewall 212 and left side sidewall 213 and being divided into two parts with partition wall 214 that top sidewall 210 links to each other with bottom sidewall 211.Be right axial cavity by what top sidewall 210, bottom sidewall 211, partition wall 214 and right sidewall 212 defined, this right side axial cavity has the first relative right opening 207a and the second right opening 208a at axial direction; And being left axial cavity by what top sidewall 210, bottom sidewall 211, partition wall 214 and left side sidewall 213 defined, this left side axial cavity has the first relative left opening 207b and the second left opening 208b at axial direction.In addition, on the top of partition wall 214, be formed with recess 219.
Body exterior is provided with a pair of lug 201 and 202.Lug 202 is positioned on the right sidewall 212, and another lug 201 is positioned on the sidewall 213 of left side.Lug 201 and 202 is used for adapter 100 is fixed on a surface.The inside of the cavity of body 205 comprises a pair of spine 235 and 236, this is positioned on the inside surface of bottom sidewall 211 to spine 235 and 236, this passes partition wall 214 to spine 235 and 236 partition wall 214 is divided into two parts, and substantially perpendicular to the axial cavity of body 205.
Parallel spine 235 and 236 defines groove 238, and this groove 238 is perpendicular to the axial cavity of body 205.The centre position place of groove 238 between the first opening 207a, 207b and the second opening 208a, 208b.Two parts 410 that the width of groove 238 equals inner housing and thickness after 420 flange 450 combines.Each right side wall 212 all has groove 239 with left side wall 213, and groove 239 and groove 238 are in line.And be formed with the recess 237 that is connected with groove 239 separately in the junction with right sidewall 212 and left side sidewall 213 of lug 201,202, wherein two recesses 237 and groove 239 are in line.
Access opening 250 and be positioned on the top sidewall 210, can allow the inner housing 410 and 420 of two parts to insert in the axial cavity of body 205, also can allow to form body 205 in injection molding mode.
The inner housing 410 and 420 of two parts is identical, and forms with plastic cement in injection molding mode.The inner housing of each part comprises the right cylinder 440 of two hollows, then is provided with roughly rectangular flange 450 at an end of right cylinder 440.The inner housing 410,420 of two parts links together by flange 450 separately, so that define two common right cylinders.The gross thickness of two flanges 450 equals the width of groove 238 and 239.In the time of in the assembly with inner housing 410 and 420 is positioned over body 205, the flange 450 of the inner housing 410 of a part is slipped in the groove 238 and 239 of body 205, and the inner housing 420 of another part is also put into body 205 in an identical manner.
The inner housing 410 of two parts and 420 right cylinder 440 are coaxial in body 205, and define two common right cylinders.Columniform sleeve (sleeve) 500 is positioned at common right cylinder.300 of cover plates have the strip teat 330 of bottom surface 320 and rectangle, and wherein teat 330 is arranged on the bottom surface 320, and corresponding with the recess 219 on partition wall 214 tops, and can be contained in the recess 219.And on teat 330, be provided with a smaller projection 332, and its bottom surface is a rectangle, xsect then is a triangle.In addition, cover plate 300 also has a pair of auricle 310, this a pair of auricle 310 respectively with lug 201,202 on recess 237 corresponding (referring to Fig. 5).
When assembling fiber adapter 200 of the present invention, the inner housing 410 and 420 of two parts is inserted in the axial cavity of body 205 by accessing opening 250.Then the projection on the cover plate 300 332 is melted by for example ultrasonic, and cover plate 300 covered accessing on the opening 250, at this moment teat 330 will be inserted in the recess 219 on the partition wall 214, and therefore the projection 332 of fusing then can be limited in the recess 219, and binds with partition wall 214.Because the auricle 310 on the cover plate 300 is corresponding with the recess 237 on the lug 201,202, when cover plate 300 covers when accessing on the opening 250, auricle 310 is positioned at recess 237.
When using fiber adapter 200, connector 100 is pushed in the body 205 from the first right opening 207a, the projection 121 that is positioned at this moment on the two opposite sides of lug 126 of door bolt 120 can be downward because of the effect deflection of projection 262, and 140 of the sleeve pipes of connector 100 can penetrate in the sleeve 500 of adapter 200.When projection 121 by after the projection 262 owing to be subjected to its restriction, projection 121 can pop up because of the elastic force of self, and makes projection 121 be positioned at the rear of projection 262, prevents that connector 100 from pulling out backward.Another connector 100 also is to insert in the same way in the second right opening 208a of body 205, makes its sleeve pipe 140 penetrate the other end of sleeve 500, contacts with the sleeve pipe 140 of other end connector 100, thereby reaches the purpose of butt joint.Similarly, connector 100 also can insert in the first left opening 207b and the second left opening 208b of body 205, thereby reaches the purpose of butt joint.
Fiber adapter of the present invention also can be designed to dock four to (eight) joints of optical fibre (figure does not show), that is intrinsic axial cavity is divided into four parts by three parallel each other partition walls, and eight joints of optical fibre can insert in the opening of two axial ends of the axial cavity of being separated by four partition walls and form butt joint.Because other structure of the fiber adapter of this part is identical with the structure of fiber adapter 200, does not repeat them here.
Because the body of fiber adapter 200 of the present invention is integrally formed, can therefore avoid the problem of being derived with the welding of ultrasonic mode.
Though the present invention discloses with aforementioned embodiments, so it is not in order to limiting the present invention, any those skilled in the art without departing from the spirit and scope of the present invention, when doing various changes and modification.Therefore protection scope of the present invention is as the criterion when looking the accompanying Claim person of defining.
