Description

Optical fiber connector

Technical field

The utility model relates to a kind of parts of optical fiber mating, more particularly to a kind of optical fiber connector.

Background technique

It refering to fig. 1, is an existing optical fiber connector 1, it is described suitable for being plugged on the spliced eye 100 of an adapter 10 The spliced eye 100 of adapter 10 have a main bore portion 101 and one be formed in the main bore portion 101 side keyway portion 102. The optical fiber connector 1 includes that a body unit 11, one is connected to the termination unit 12 of 11 rear end of body unit and a set of It is connected to the body unit 11 and is connected to the socket unit 13 in 12 front of termination unit.Wherein, the body unit 11 Shape be the main bore portion 101 for cooperating the spliced eye 100, suitable for mating when be inserted in the main bore portion 101.

The body unit 11 includes two panels 111 and two that are spaced in parallel to each other and being respectively formed with a groove 119 It is a to be connected respectively in the side plate 112 of the two opposite sides of the panel 111.In order to make the optical fiber connector 1 be able to cooperate described insert The kenel in hole 100 is connect, the termination unit 12 includes two and is stacked and placed on the substrate 121 of the panel 111 respectively (because of the visual angle Fig. 1 Relationship only visible one), the engagement plate 122 of two two opposite ends for being connected the substrate 121 respectively and one is from a wherein substrate 121 extend forward and can be cooperatively connected direction and select to be disposed therein in a groove 119, and are suitable for stretching being placed in the keyway The connecting key 123 in portion 102.

Simultaneously refering to fig. 1 with Fig. 2, since the adapter 10 has the keyway portion 102 to be located at two kinds of not ipsilateral specifications, As long as changing the direction that 12 end of termination unit is connected to the body unit 11, the connecting key 123 is made to be disposed therein one In the groove 119 of a panel 111, that is, it is able to cooperate the position in the keyway portion 102 of the adapter 10, changes the connecting key 123 Position, the optical fiber connector 1 is plugged in really in the spliced eye 100 of the adapter 10.

However, in order to enable the termination unit 12 can be fixed on the body unit 11 really, it is necessary to penetrate the set Order member 13 positions, although this connection type can fix the termination unit 12 really, the optical fiber described in grafting is avoided to connect When generating and fall off when connecing device 1, but being intended to dismantle the termination unit 12 and convert the specification of the optical fiber connector 1, but also it is necessary The socket unit 13 is dismantled together with the termination unit 12, could be re-assemblied again to cooperate the adapter 10 The optical fiber connector 1 of specification.Other than adjusting all components must be dismantled the tedious steps assembled again every time, add On at present for the size microminiaturization demand of the optical fiber connector 1, and increase the difficulty of assembling, not only take a lot of work and suitable expense When, it is still not very convenient in use.
