Abstract

The invention relates to a parallel thermal shrinkage joint which is used when multiple strands of wires for electric power operation are fixedly connected together side by side by one terminal. The parallel thermal shrinkage joint is characterized in that a plurality of side-by-side branch pipes are connected to one side of a header pipe, the outer layer of the cross section of each branch pipe is an insulating layer, a conductive layer is arranged at the inner side of the inner layer of the cross section of each branch pipe, a bonding layer is arranged at the outer side of the inner layer of the cross section of each branch pipe, a conductive joint is arranged at the other side of the header pipe, and the conductive layer of each branch pipe is electrically connected with the conductive joint of the header pipe. The insulating layers of the header pipe and each branch pipe are respectively made of a polymer shape memory material, and the conductive layer of each branch pipe is formed by wrapping wires with a meshy flexible conductive metal material and annularly arranging the wrapped wires on the inner wall, and the bonding layer of each branch pipe is composed of adhesive tapes. The parallel thermal shrinkage joint can be used for enabling a multiwire joint to be in reliable contact with a wiring terminal and is attractive to wire and convenient to assemble and disassemble, and the working efficiency and the working quality are improved.

Description

The doubling pyrocondensation joint

Technical field

Patent of the present invention belongs to the T ﹠ D Technology field, when particularly strand wire and head share place's terminal and connect and line technology.

Background technology

At present with in the same terminal hole of strand wire head access during operation, be generally that many nuditing wires is first and be pressed into or insert in same binding post hole.Generally be subject to the limited Wiring port restriction of intrinsic shaped article when adopting also wire terminal operation.Line method carries out wiring with regard to adopting also when having limited port limit, as: multiply holding wire, control line, power line are shared same Wiring port etc.There is following shortcoming in the first and mode of connection that be pressed into or insert in same binding post hole of many nuditing wires: one, multi-thread doubling and intrinsic electric equipment port do not configure and have that virtual connection hidden danger, virtual connection hidden danger can cause loose contact, the joint is overheated and damage electric equipment.Two, multi-thread doubling wiring operating process is wasted time and energy.

Summary of the invention

The purpose of patent of the present invention is a kind of device that multiple conducting wires is connected in parallel of development, and its technical scheme is as follows.

A kind of doubling pyrocondensation joint, its special character is the some arms side by side of side connection house steward, the skin of each arm cross section is insulating barrier, the inboard of internal layer is that conductive layer, the outside are adhered layers, opposite side house steward is installed conductive contact, the conductive layer of each arm all electrically connects with house steward's conductive contact, and house steward's sidewall is insulating barrier.

The insulating barrier of house steward and each arm is made by polymer shape memory material, and after the conductive layer of arm adopts netted soft conductive metallic material parcel wire or strip conductive metallic material clamping wire, the annular adhered layer that is installed on inwall formation, arm is made of adhesive tape.After wire inserts heat-shrink tube, adopt heat gun to be heated to the 60-100 degree to arm, make arm produce pyrocondensation distortion and stranded conductor crust adhesive seal, shrink secure wires.

The doubling pyrocondensation joint is comprised of house steward and arm, its arm can be two-tube, three the pipe, four the pipe etc.

When adopting the doubling pyrocondensation joint to carry out the doubling operation, the wire head that only needs to need doubling directly inserts in arm after according to the technological standards shedding, then add hot leg pipe and make its pyrocondensation tighten up wire head, at last the conductive contact in the house steward of doubling pyrocondensation joint is inserted the doubling operating procedure of completing multiple conducting wires in the binding post that matches.

Adopt the operation of this doubling pyrocondensation joint to have following advantage: multiple conducting wires is contacted reliably, wiring is attractive in appearance, mounting or dismounting are convenient with binding post, increase work efficiency and work quality.

Embodiment

The below's contrast accompanying drawing narration embodiment.

A kind of doubling pyrocondensation joint, it is the some arms 7 side by side of end connection house steward 8, the skin of each arm 7 cross sections is insulating barriers 1, the inboard of internal layer is that conductive layer 2, the outside are adhered layers 3, at house steward 8 opposite side, conductive contact 6 is installed, the conductive layer 2 of each arm 7 all electrically connects with house steward 8 conductive contact 6.

As Fig. 2, Fig. 3 and shown in Figure 4, the arm 7 in the doubling pyrocondensation joint can be two-tube, three the pipe or four the pipe etc.

When adopting the doubling pyrocondensation joint to carry out the doubling operation, the wire 4 that only needs to need doubling directly inserts in arm 7 after according to the technological standards shedding, then add hot leg pipe 7 and make its pyrocondensation tighten up wire head 4, make conductive layer 2 close contacts of exposed wire head 5 and arm 7.At last the conductive contact 6 in the house steward 8 of doubling pyrocondensation joint is inserted the doubling operation of completing multiple conducting wires in the binding post that matches.
