Abstract

The utility model provides a straight-plugging type electric cable connector, composed of a casing and internal structural members, and both ends of the connector are respectively provided with a spigot. The internal structural members comprise a separator, a spring, a claw fastening collet and a supporting fastening collet bracket, composing a tightly fitted link construction and a conductive path. When a power cable broken end with a sheath cap is connected, the claw fastening collet generates clamping force to the power cable broken end through the combined action of the external force and the spring force, consequently achieving the purpose of connecting the power cable broken end. The utility model has the advantages of easy process, reliable quality of connection, simple operation, labor saving, time saving, high efficiency, and fast connection of power cables under various environments.

Description

Direct insertion power cable coupling

The utility model is the direct insertion coupling that a kind of power cable is used.

Fast development along with Chinese national economy, industry, agricultural, national defence and civilian required electric power consumption are increasing, thereby the paved surface of power cable is more and more wider, it is also more and more longer to lay distance, cause the consumption of power cable coupling also to roll up thus thereupon. the existing power cable coupler has many kinds, but all there is the joint loose contact at the scene in the work progress, fastening not firm, can not realize shortcomings such as connection fast, and a kind of power cable coupling (patent No. ZL 95242666.8) that our design has also been applied for a patent, though overcome above shortcoming, but it only can realize connecting fast to the less power cable of bore, when the cross-sectional area of required tie cable more than 80 square millimeters the time, because its mounting bracket can contain the limited of area, cause cable effectively not contained, thereby influence the fastening performance of connection of coupling.

The utility model has overcome above limitation, can be according to the size of cable cross-sectional area, and pawl formula mounting bracket, support and the supporting with it metal sleeve of design different size, guaranteeing that the cable broken end is contained fully, the utmost point guarantees the fastening performance that connects effectively.

Direct insertion power cable coupling provided by the utility model, support by shell, separator, spring, pawl formula mounting bracket and support mounting bracket is formed, it is characterized in that the center position in shell 1 is mounted with separator 2, two ends at separator are mounted with spring 3 respectively, be mounted with pawl formula mounting bracket 4 in the end of spring, pawl formula mounting bracket supports (seeing accompanying drawing 1) by support 5.During use, earlier cable broken end 6 usefulness cap bags 7 are entangled (dispersing) to prevent the cable broken end, again the cable broken end is sent into by two ports of coupling respectively, when the cable broken end heads on pawl formula mounting bracket 4, overcome the effect of spring 3 spring forces because of the external force effect by three pawl formula mounting brackets of support 5 supports, move and open gradually toward the shell 1 interior middle part of pine, and cable broken end 6 is sent between three pawl formula mounting brackets 4, after cable broken end 6 is sent into certain-length, with the external force cable 6 that pulls outward, this moment, pawl formula mounting bracket 4 moved outward with cable 6, because shell 1 two ends are the circular cone cavity with certain taper, thereby pawl formula mounting bracket 4 is closed gradually when mobile outward, when acquiring a certain degree, the male cone (strobilus masculinus) of pawl formula mounting bracket 4 and the inner conical surface of shell 1 closely cooperate, pawl formula mounting bracket 4 can not move again, then cable broken end 6 is tightly contained fastening by pawl formula mounting bracket 4, simultaneously because the buttless thread of pawl formula mounting bracket 4 inner surfaces has further strengthened break end frictional force between 6 of joint 4 inner surfaces and cable, thereby improved the tensile strength of coupling greatly.Through above process, just can reach the purpose that connects power cable.

Direct insertion power cable coupling of the present utility model, processing easily, reliable in quality, when connecting, do not need aid, thereby this direct insertion power cable coupling in use, and connecting mode is easy, under various operational environments, the quick connection of power cable can be realized, thereby the speed of power cable can be accelerated to lay and keep in repair greatly.

In conjunction with the accompanying drawings, further specify the utility model by embodiment.

Shell 1 is a metal pipe material, and the centre is a bit of to be cylindrical cavity shape, and two ends are the conical cavity shape with two taperings; Separator 2 is thin metal cylinder, and the inner cavity size of its overall dimension and shell 1 interlude cylindrical cavity matches; Spring 3 usefulness 65Mn spring steel coilings form, and the external diameter of spring is less than the overall dimension of separator 2, to guarantee that spring can freely stretch in shell 1; Pawl formula mounting bracket 4 is the alloy aluminum die casting, and outer surface is a half cone-shaped, and inner surface is fan-shaped, and has buttless thread; Support 5 profiles are the depression that a regular hexagon and three sidebands at interval have certain depth, and to cooperate with pawl formula mounting bracket, inner surface is a circular hole, and the size of circular hole is determined by cable dimension; Cap bag 7 is selected the metal material punch forming of 0.7mm for use.The part that processes is assembled moulding by Fig. 1, promptly constitute direct insertion power cable coupling provided by the utility model.
