Embodiment 1

[0056] Such as Figure 3 to Figure 5 As shown, the connector assembly includes a socket connector and a plug connector, with the plug end as the front end, the socket connector includes a socket housing 11, and the inner wall of the socket housing 11 is provided with a protrusion 22, and the protrusion 22 is along the left and right direction There are two in a symmetrical arrangement.

[0057] In this embodiment, the plug connector includes a plug housing 13, and a ferrule 12 is arranged inside the plug housing 13. The ferrule 12 includes a plug 14, a locking shrapnel 15, an unlocking shrapnel 16 and a pull ring 17; the locking shrapnel 15 is set On the upper surface of the plug 14, the rear end of the locking shrapnel 15 is an upturned free end, and the locking shrapnel 15 can lock the plug 14 in the jack of the socket connector; the front end of the unlocking shrapnel 16 is an upturned free end. The free end, the free end of the unlocking elastic piece 16 extends above the...

Embodiment 2

[0070] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the movable part is an elastic arm 21, and the elastic arm 21 can swing back and forth along the radial direction of the plug housing 13, so that the corresponding slot on the elastic arm 21 25 and the projection 22 snap fit, and then the elastic arm 21 is limited by the limit portion 23 at the front end of the plug housing 13 . And in this embodiment, if Figure 9 As shown, the socket housing 31 is provided with a protrusion 35, the plug housing 32 is provided with a ferrule 33, the ferrule 33 is provided with a sliding hole, the movable part is a slider 34, and the slider 34 can move along the plug housing 32. The radial reciprocating slide of the slider 34 makes the corresponding slot 37 on the slider 34 engaged with the protrusion 35 ; after that, the slider 34 is limited by the stopper 36 at the front end of the plug housing 32 .

Embodiment 3

[0072] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, there are two elastic arms 21, which are respectively arranged on the left and right sides of the ferrule 12, and the elastic arms can swing back and forth along the radial direction of the plug housing 13. , so that the corresponding slot 25 on the elastic arm 21 engages with the protrusion 22 , and then the elastic arm 21 is limited by the limit portion 23 at the front end of the plug housing 13 . And in this embodiment, if Figure 10 and Figure 11 As shown, the socket housing 41 is provided with a protrusion 47, and the plug housing 42 is provided with a ferrule 43. The ferrule 43 includes a locking elastic piece 44, an unlocking elastic piece 45 and an elastic arm 46. The elastic arm 46 is provided with one and integrated Formed on the unlocking spring 45, the outer side of the elastic arm 46 is provided with a card slot 49, and there are three card slots 49 arranged at intervals alon...

Abstract

The invention relates to a plug connector and a connector assembly. The plug connector comprises: a plug shell; an insertion core which is arranged in the plug shell, wherein the insertion end of the insertion core serves as the front end, a movable part is arranged on the insertion core and can move in a reciprocating mode in the radial direction of the plug shell, a plurality of clamping grooves are formed in the outer side of the movable part at intervals in the front-back direction, and the clamping grooves are used for being matched with protrusions on the inner wall of the socket shell in a clamped mode; and a limiting part which is located at the front end of the plug shell, wherein after the corresponding clamping grooves are clamped and matched with the protrusions on the inner wall of the socket shell, the limiting part is located on the inner side of the movable part so as to limit the movable part at the clamping position. According to the plug connector, floating of the insertion core is achieved, the plug connector can be suitable for transceiving modules of different models within a certain range, meanwhile, the length of the plug connector is small, and miniaturization of products is facilitated. In addition, through clamping cooperation of the clamping grooves and the protrusions, the tensile strength of the insertion core in the front-back direction is improved, and the stability of the insertion core is guaranteed.

Description

technical field [0001] The invention relates to a plug connector and a connector assembly. Background technique [0002] In the prior art, the connection methods of optical fiber connectors are generally divided into two types, the first one is as figure 1 As shown, the socket connector 103 and the plug connector 104 are respectively connected to the two transceiver modules 101 through two optical cables 102, and then the plug and socket connectors are plugged together to realize the conduction of the two transceiver modules 101; Two such as figure 2 As shown, the socket connector 203 is arranged on one of the transceiver modules 201, the plug connector 204 is connected to the other transceiver module 201 through the optical cable 202, and then the plug and socket connectors are plugged together to realize the two transceiver modules 201 conduction. Since the connection of the second type is simpler than that of the first type, the connection mode of the second type of o...
