Abstract

The invention discloses a guy-wire-knockout electric connector and a guy-wire-knockout electric connector assembly. The surface of a guy-wire-knockout electrical connection housing is rotationally equipped with a lever locking arm which is movable freely back and forth or up and down relative to the surface of the housing. The front end of the lever locking arm is provided with a barb for fitting a corresponding socket, while the rear end of the lever locking arm is convexly provided with a baffle plate facing towards the housing. The guy wire is connected with a bending piece pressed between the rear end of the lever locking arm and the surface of the housing. The housing is further provided with an elastic reset mechanism which locks the front end of the lever locking arm and the socket. An unlocking element and a locking element of the guy-wire-knockout electric connector adopt the bending piece and the lever locking arm, and the bending piece can turn over and support the rear end of the lever locking arm when pulled by the guy wire, so the unlocking action of the bending piece can be realized by unfolding the bending piece. Furthermore, the bending piece can be closed and reset under the action of self elastic force, so the connector can be simply, conveniently and reliably dismounted without overcoming a big reset resistance during unlocking and locking.

Embodiment

As Fig. 1～shown in Figure 7, a specific embodiment of backguy breakaway connector of the present invention is the electric module of a kind of SFP high speed, in use with cage socket 11 insertings.Electric module of SFP high speed and cage socket 11 constitute backguy breakaway connector assembly.

Cage socket 11 is established the hollow cage body of opening for inserted terminal, and near the inserted terminal opening around sidewall be provided with the arc spring lamination 11-1 that turns up.The SFP module comprises the connector shell of being made up of upper and lower casing 1,7, and housing has the inserted terminal and the cable feeding end that is used for cable 13 feedings with the 11 corresponding insertings of cage socket, does not show cable among Fig. 1, Fig. 2.The cable of SFP module housing feeds on the end and also is connected with sheath 5.The surface of the upper shell 1 of SFP module is provided with a pair of

shoulder

14,15, shoulder 14, be rotatably equipped with the bar hammerlock 4 of relative upper shell 1 surface undulation swing between 15 by a horizontal bearing pin 3, bar hammerlock 4 rotate to it axis before, back two ends feed end towards the inserted terminal and the cable of SFP module housing respectively, the top of bar hammerlock 4 front ends is provided with the barb 10 that cooperates with the 11 corresponding lockings of cage socket, the end face of barb 10 is approximately triangle, the end face of the inserted terminal of cage socket 11 is provided with the leg-of-mutton hole 12 that snaps in barb 10 corresponding matching, and bar hammerlock 4 rear ends convex with the block 9 towards upper shell 1.Other is provided with the draw ring 6 that is connected on the SFP module, draw ring 6 is connected with the bent sheet 8 that is fitted between bar hammerlock 4 rear ends and upper shell 1 surface by backguy, one end of bent sheet 8 lower floors is connected with draw ring 6, turn up and bend the inserted terminal extension of back to housing in the upper strata, and the end of bent sheet 8 cooperates with described block 9 roof pressures.

Be set with shielding spring 2 on the housing of SFP module in position near the hangnail 10 of bar hammerlock 4.Shielding spring 2 comprises hollow sleeve and is extended with respect to the turn up elastic spring 2-2 of perk of SFP module housing surface around the body, elastic spring 2-2 is used for compressing contact matching with the arc spring lamination 11-1 of cage socket 11 inserted terminals, and the top of shielding spring 2 is provided with internally resilient abutment at the protruding elastic piece structure 2-1 of bar hammerlock 4 front end bottom surfaces.

The present invention's releasing process in use: along A among Fig. 1 to the pulling draw ring 6, because the terminal roof pressure of bent sheet 8 is on bar hammerlock 4, when draw ring 6 stressed toward A to mobile the time, the top section of bending sheet 8 will rotate counterclockwise round bent sheet 8 bending parts, thereby rotate counterclockwise an angle with the rear end jack-up of bar hammerlock 4 and around bearing pin 3, the front end that makes bar hammerlock 4 is towards the direction motion near housing, the barb 10 of bar hammerlock 4 front ends and the triangle opening 12 of cage socket 11 are separated, thereby easily the SFP module are extracted from cage socket 11.After the SFP module is taken out in cage socket 11, because 4 pairs of bar hammerlocks shield shell fragment corresponding on the spring 2 when taking out the SFP module compression is arranged, after making that SFP extracts, 2 pairs of bar hammerlocks 4 of shielding spring have the effect of a restoring force, 4 pairs of bent sheet 8 of bar hammerlock also have individual restoring force effect simultaneously, thereby make bar hammerlock 4 and bent sheet 8 return to original state.

Be used for the mechanism that bar hammerlock 4 resets in the foregoing description and be shielding spring 8, shielding spring 8 plays the function of shielding and restoring lever hammerlock 4 simultaneously.If only consider resetting of bar hammerlock 4, can certainly adopt the flexible restoring organ that lever swing is resetted of other form, such as on bearing pin 3, installing torsion spring additional, install shell fragment additional at hammerlock 4 front ends and constitute other forms of flexible restoring organ.
