Abstract

The utility model relates to a buckling device for cable connectors, comprising an upper shell and a lower shell, and the upper shell and the lower shell are hollow shell bodies. Four clamping hooks extend near four corners of a butting surface of the upper shell to the lower shell, two corners of the butting surface are concavely provided with two post slots, and a butting surface of the lower shell is convexly provided with two guiding posts. An inner side wall surface of the lower shell is concavely provided with four locking slots which are respectively corresponding to the post slots and the clamping hooks of the upper shell. Two locking slots of the lower shell near the guiding post are respectively and convexly provided with blocks, the blocks can be used for guiding and protecting the stopping the clamping hooks, so the clamping hooks can be avoided from over deformation and breaking, and the clamping hook can be prvented from separating from the locking slot.

Description

The wire and cable connector fastening device

The utility model relates to a kind of wire and cable connector fastening device, refers in particular to a kind of wire and cable connector fastening device that grab inserted and avoided grab generation fracture situation of guiding.

Because composition structure such as the plug and the metal wire etc. of wire and cable connector are very meticulous, use often to cause the junction of metal wire fracture or metal wire and plug to break away from because of the artificial strength of pullling.For solving this class problem, industry generally is provided with a fastening device on wire and cable connector, this fastening device is by being fastened on the upper and lower casing on the cable, plastic cement crust one activity with cable, therefore the outside exhausted major part of strength of pullling is all born by the plastic cement crust of fastening device and cable, breaks away from so can avoid the junction of metal wire fracture or metal wire and plug to produce.

A kind of structure of existing fastening device can be with reference to the 5th, 017, No. 157 patent cases of the U.S., as shown in Figure 1, this fastening device comprises a upper shell 2 and a lower house 3, and wherein upper shell 2 is provided with grab 4, the buckle slot 5 that is used for buckle lower house 3 is fastened on the cable fastening device integral body.Yet, because this design is too simple, when upper shell 2 cooperates with lower house 3 mutual buckles, grab 4 is often because of docking the inaccurate fracture that produces, and after grab 4 buckles were gone into buckle slot 5, if be subjected to the artificial strength of reversing, grab 4 very easily produced distortion and breaks away from buckle slot 5, even produce the situation of fracture, cause fastening device to get a desired effect.

The wire and cable connector fastening device that provides a kind of housing to be provided with block is provided the purpose of this utility model, this block structure can not influence under the flexible situation of grab, guarantee that grab is unlikely because of ruptured by unsuitable external force excessive deformation, can avoid grab simultaneously because of docking the inaccurate fracture situation that produces.

The technical solution of the utility model is: this wire and cable connector fastening device comprises upper shell and the lower house that is used to be fastened on the wire and cable connector, and this upper and lower casing all is made as hollow housing, with the corresponding part of ccontaining wire and cable connector.Be extended with four grabs towards lower house near four corners of upper shell interface, and two corners at interface are concaved with two post grooves, then convex with two guide posts on the interface of lower house, and the appropriate location near four jiaos on the interior sidewall surface of lower house is concaved with four buckle slots, respectively the post groove and the grab of corresponding matching upper shell.Described lower house convexes with a block respectively in two buckle slots of contiguous guide posts, be used for guiding and block grab to produce fracture to avoid grab because of excessive deformation, and prevent that grab breaks away from buckle slot.

Owing to adopted technique scheme, upper and lower casing butt joint of the present utility model accurately, and the grab on the housing can not rupture because of the strength of pullling of outside, thereby makes this fastening device have advantages such as stable performance, long service life.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 6 is the three-dimensional exploded view of another embodiment of the utility model.

As shown in Figures 2 and 3, the utility model wire and cable connector fastening device 10 comprises upper shell 20 and the lower house 30 that is used to be fastened on the wire and cable connector 100, this upper shell 20 all is made as hollow housing with lower house 30, with the corresponding part of ccontaining wire and cable connector 100.Please cooperate and consult Fig. 4 and Fig. 5, be extended with four grabs 12 towards lower house 30 near four corners of described upper shell 20 interfaces 24, and two corners at interface 24 are concaved with two post grooves 26 (shown in Figure 5), then convex with two guide posts 40 on the interface 25 of lower house 30, just can be housed in respectively in the two post grooves 26 of upper shell 20 correspondences, and the appropriate location near four jiaos on the interior sidewall surface of lower house 30 is concaved with four buckle slots 32, be used to keep supplying the grab 12 buckles cooperation of housing 20 correspondences, in two buckle slots 32 of contiguous guide posts 40, convex with a block 14 respectively, this block 14 is the vertical type cylinder, its upper end is provided with inclined-

plane

18, and 18 belows, inclined-plane link to each other with inclined-plane 18 is vertical plane 16, and inclined-plane 18 and vertical plane 16 are all towards buckle slot 32 (shown in Figure 5).

As shown in Figure 5, when upper shell 20 and lower house 30 mutually combine, the grab 12 of upper shell 20 will contact the inclined-plane 18 of lower house 30

blocks

14, and 18 successfully slip into and be buckled in the buckle slot 32 along the inclined-plane.By block set on the lower house 30 14, when upper shell 20 with after lower house combines, if be subjected to the artificial strength of reversing, the vertical plane 16 of this block 14 can be used to block grab 12, avoid grab 12 because of excessive deformation produces fracture, and prevent that grab 12 breaks away from buckle slot 32.

See also the three-dimensional exploded view of another embodiment of the utility model shown in Figure 6, wherein this block 14 ' be located at upper shell 20 ' on, it is substantially square cylinder, be positioned at upper shell 20 ' inboard and with grab 12 ' maintenance appropriate intervals, when grab 12 ' when being reversed strength and be out of shape, near this grab 12 ' block 14 ' butt on it, thereby prevent grab 12 ' excessive deformation.
