Abstract

The utility model pertains to the technical field of transformers and discloses a novel connection structure of leading-out terminals and leading-out wires of a high-voltage transformer. The connection structure comprises leading-out wire terminals of the transformer connected with a transformer body and the leading-out wires used for being connected with the leading-out wire terminals of the transformer. The novel connection structure is characterized in that: the end portion of each leading-out wire is provided with a leading-out wire stripping head with an insulating layer removed; the end surface of each leading-out wire stripping head is in butt joint with the end surface of each leading-out wire terminal of the transformer; the novel connection structure also comprises copper sleeve pipes arranged at butt-joint parts of leading-out wire stripping heads and the leading-out wire terminals of the transformer; tin is arranged at each gap part in each copper sleeve pipe; and an insulating sleeve sleeves the outer wall of each copper sleeve pipe. By adoption of the above technical scheme, the novel connection structure of the leading-out terminals and the leading-out wires of the high-voltage transformer has following beneficial effects over a conventional connection structure: the novel connection structure has good fastening performance so that spikes and unevenness caused by scattered multiple strands of wires are well avoided; stability of soldering tin is well ensured due to the presence of the copper sleeve pipes; and the qualified rate of products is further improved.

Description

A kind of novel high-pressure transformer exit and outgoing line connection structure

Technical field

The utility model relates to transformer technology field, particularly relates to a kind of novel high-pressure transformer exit and outgoing line connection structure.

Background technology

At present, in the use procedure of high-tension transformer, often need to utilize lead-out wire that transformer lead-out wire terminal is connected with peripheral hardware, traditional connection procedure is, first one section of insulating barrier is rejected in the end of lead-out wire, thereby obtain lead-out wire stripping head, then lead-out wire stripping head is welded or overlapped with transformer lead-out wire terminal; Find by practice, this syndeton produces spine and uneven because multi cord is easy to scatter in welding or crimping operation, and scolding tin easily occurs rosin joint, welds the phenomenons such as unreal.In the time of wrap insulate material, be easy to stab or puncture insulating material, and produce hidden danger of quality such as causing insulation decline, insufficient load current, even product is defective.

Utility model content

The technical problems to be solved in the utility model is: a kind of connect fastening, unfailing performance is high novel high-pressure transformer exit and outgoing line connection structure are provided.

The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:

A kind of novel high-pressure transformer exit and outgoing line connection structure, comprising: the transformer lead-out wire terminal being connected with transformer body and be connected the lead-out wire of use with transformer lead-out wire terminal; The end of described lead-out wire is provided with one section of lead-out wire stripping head of rejecting insulating barrier; The end face of described lead-out wire stripping head and the end face of transformer lead-out wire terminal connect; Also comprise the copper sleeve that is placed on described lead-out wire stripping head and transformer lead-out wire terminal joint, the gap in described copper sleeve is provided with tin, has insulating case at the outer wall cover of described copper sleeve.

Advantage and the good effect that the utlity model has are: by adopting technique scheme, the utility model, compared with conventional art, has better tightness, can prevent well that multi cord from scattering and producing spine and uneven; Due to the existence of copper sleeve, can guarantee well scolding tin steadiness; And then the qualification rate of raising product.

Embodiment

For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1 and Fig. 2, a kind of novel high-pressure transformer exit and outgoing line connection structure, comprising: the transformer lead-out wire terminal 2 that is connected with transformer body 1, be connected the lead-out wire 4 of use, go out to overlap have copper sleeve 7 at transformer lead-out wire terminal 2 with the connecting portion 3 of lead-out wire 4 with transformer lead-out wire terminal 2; The end of lead-out wire 4 is provided with one section of lead-out wire stripping of rejecting insulating barrier 6; The end face of lead-out wire stripping 6 and the end face of transformer lead-out wire terminal 2 connect; Copper sleeve 7 is placed on lead-out wire stripping 6 and transformer lead-out wire terminal 2 joints; Gap in copper sleeve 7 is perfused with tin liquor, and after tin liquor is cooling, tin 8 is filled the space in full copper sleeve 7, has insulating case 5 at the outer wall cover of copper sleeve 7.

Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
