Description

A kind of terminal connecting line

Technical field

The utility model belongs to terminal connecting line field, is specifically related to a kind of terminal connecting line.

Background technique

In design of electronic products, terminal connecting line can be used, and existing terminal connecting line is when producing installation, terminal Connected with the core in wire rod it is extremely inconvenient because rubber shell be it is fixed on the insulating layer, it is therefore desirable to line skin is removed too long Distance after connection, needs for terminal to be inlaid in rubber shell so as to have certain space that can connect with terminal, due to There are too long core and line skin, and the inner space in rubber shell be it is constant, in terminal in indentation, it is existing to be easy to happen short circuit As, and be easy to damage by pressure line skin, therefore need a kind of novel terminal connecting line, to solve the above problems.

Utility model content

The purpose of this utility model is in view of the above problems, providing a kind of terminal connecting line, it is intended to solve wire rod and terminal After connection, it is pressed into the problem that rubber shell is easy to appear short circuit.

In order to achieve the above object, the technical solution adopted in the utility model is, it include wire rod, be wrapped in it is exhausted outside wire rod Edge layer, the first connector and the second connector that wire rod two sides are set, in which:

Second connector includes rubber shell, the terminal connecting with core in wire rod and the extension bar axis being fixed on outside insulating layer, The rubber shell is set in extension bar axis outer wall, the clamping cavity for being used to be embedded in terminal with one in the rubber shell, when rubber shell is embedded in end When son and core connection terminal, the rubber shell is separately fixed at the two sides of extension bar axis.

Further, the rubber shell is connect with extension bar axle thread.

Further, the rubber shell is made of tool internal thread pullover with the terminal connector with clamping cavity；Institute Stating extension bar axis includes end and shaft, has external screw thread on the shaft, pullover is threadedly coupled with shaft.

Further, there is elastic chuck on the terminals side end surface, be provided on the clamping cavity of terminal connector The bayonet matched with elastic chuck.

Compared with prior art, the utility model has the beneficial effects that when core connection terminal, wire rod is stretched out into rubber shell, Shorter line skin need to be only stripped at this time, exposes certain core, avoid that short circuit phenomenon occurs；When rubber shell is embedded in terminal, Rubber shell is screwed out, the wire rod of stretching is covered, then carries out terminal and is embedded in, so as to avoid damaging by pressure in wire rod, together there are biggish space When be beneficial for disassembly and assembly maintenance.

Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model There is any restriction effect.

As shown in Figure 1-Figure 3, the utility model provides a kind of terminal connecting line, it includes wire rod 40, is wrapped in wire rod 40 Outer insulating layer 10, the first connector 20 and the second connector 30 that 40 two sides of wire rod are set, wherein the second connector 30 wraps Include rubber shell 31, the terminal 32 connecting with core in wire rod 40 and the extension bar axis 33 being fixed on outside insulating layer 10, the rubber shell 31 It is set in 33 outer wall of extension bar axis, the clamping cavity 3101 for being used to be embedded in terminal 32 with one in the rubber shell 31, when rubber shell 31 is embedding When filling terminal 32 and core connection terminal 32, the rubber shell 31 is separately fixed at the two sides of extension bar axis 33.

Preferably, the rubber shell 31 is threadedly coupled with extension bar axis 33.

Preferably, the rubber shell 31 is connected by the pullover 310 with internal screw thread 3110 and the terminal with clamping cavity 3101 Connector 311 forms；The extension bar axis 33 includes end 330 and shaft 331, has external screw thread 332, pullover on the shaft 331 310 are threadedly coupled with shaft 331.

Preferably, there is elastic chuck 320, the clamping cavity of terminal connector 311 on the 32 side end face of terminal The bayonet matched with elastic chuck 320 is provided on 3101.

Working principle: when core connection terminal 32, rubber shell 31 is screwed in the inner end of extension bar axis 33, stretches out wire rod 40 Rubber shell 31, the outreach of wire rod 40 can preferably be connect with terminal 32 at this time, and after connection, rubber shell 31 is screwed out, Make stretch out wire rod 40 be hidden in rubber shell 31, then, terminal 32 is inlaid in rubber shell 31, due to exposing wire rod 40 compared with Short, in insertion, terminal 32 will not cause largely to oppress to wire rod 40, avoid damaging by pressure in wire rod 40, in dismounting It is more convenient.
