In order to overcome the defects of the prior art, the utility model provides a heat-shrinkable terminal structure which can effectively solve the technical problem that an internal copper column slides during hot melting.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a pyrocondensation terminal structure, includes copper post and inside pyrocondensation pipe that switches on with both ends, the copper post is located inside the pyrocondensation pipe, the pyrocondensation pipe inner wall is equipped with the barb of at least two protruding laminating in copper post both sides face, copper post both ends are equipped with the jack that is used for plugging into the wire rod, still be equipped with the hot melt adhesive circle of distribution in both sides in the pyrocondensation pipe.

Further, the direction of the central axis of the copper column is overlapped with the direction of the central axis of the heat shrinkage tube.

Further, concave rings which are communicated end to end are arranged on the outer side faces of the copper columns.

Further, a high temperature resistant layer is arranged on the outer side face of the copper column.

Further, a gap is reserved between the hot melt adhesive ring and the copper column.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model adds the barb for limiting the movement of the internal copper column on the inner wall of the heat shrinkage tube, when the heat shrinkage tube is heated and subjected to heat shrinkage, the internal copper column is fixed in situ, the phenomenon of offset position can not occur, and meanwhile, the barb structure is convenient for the copper column to be assembled in the heat shrinkage tube in a sliding way, and the heat shrinkage tube has the advantages of simple integral structure, convenient operation and strong practicability.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-3, the utility model provides a heat-shrinkable terminal structure, which comprises a copper column 1 and a heat-shrinkable tube 2 with two ends connected inside, wherein the copper column 1 is arranged inside the heat-shrinkable tube 2, at least two barbs 3 protruding and attached to two sides of the copper column 1 are arranged on the inner wall of the heat-shrinkable tube 2, inserting holes 4 for connecting wires 8 are arranged at two ends of the copper column 1, the technical scheme is suitable for mutually slaughtering and connecting wires 8 with a male connector, the wires are fixed through the heat-shrinkable tube 2, the copper column 1 inside the heat-shrinkable tube 2 is made of hard copper materials, the heat outside is not deformed after being heated, therefore, a high-temperature resistant layer 7 with a high-temperature resistant effect is added on the outer side surface of the copper column 1, the high-temperature resistant layer 7 can simultaneously protect the copper column 1 inside and the position connected after the wires 8 are inserted, the position directions of the copper column 1 rotating inside the heat-shrinkable tube 2 are consistent, the central axes of the copper column 1 are overlapped, the positions of the copper column 1 are limited by the barbs 3 at two sides inside the heat-shrinkable tube 2, the copper column 1 can not shift before heat shrinkage, the heat shrinkage is enhanced, the heat shrinkage effect is improved, and the heat shrinkage effect of the barbs are improved, and the copper column 1 is convenient to assemble outside the heat-shrinkable tube 2.

When the heat shrinkage tube 2 is heated at high temperature, the heat shrinkage tube automatically shrinks, however, the concave ring 6 communicated end to end is additionally arranged on the outer side face of the lead column 1, the concave ring 6 enables the heat shrinkage tube 2 after heat shrinkage to be tightly attached to the surface and fixedly reinforced through the concave ring 6, and the heat shrinkage tube and the concave ring cannot slide.

Still be equipped with the hot melt adhesive ring 5 of distribution in both sides in the pyrocondensation pipe 2, the hot melt adhesive ring 5 is pyrocondensation makes sealing contact between pyrocondensation pipe 2 and the wire rod 8 under the high temperature condition, also prevents through the bellied structure of hot melt adhesive ring 5 that inside wire rod 8 from being pulled at will simultaneously, at this moment, the hot melt adhesive ring 5 distributes in both sides to leave the clearance with copper post 1 between, not laminating in the side of copper post 1.

Compared with the prior art, this technical scheme has increased the barb that restriction inside copper post 1 removed at heat shrinkage pipe 2 inner wall, and when heat shrinkage pipe 2 was heated the pyrocondensation, inside copper post 1 is fixed in place, can not appear the phenomenon of offset position, simultaneously, barb 3's structure makes things convenient for copper post 1 to slide the equipment inside heat shrinkage pipe 2.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
