Abstract
The utility model relates to a welding device of transformer leads and belongs to the technical field of transformer lead connecting devices. The welding device of the transformer leads comprises a cold pressing copper pipe body (1) and holes (2), wherein the number of the holes (2) is two and the holes (2) are symmetrically formed in the middle portion of the cold pressing copper pipe body (1). The welding device of the transformer leads has the advantages that leader cables and coil heads (round copper wires, flat copper wires and the like) of a transformer are connected with cold-pressed terminals of various types in an indentation mode so that various shortages that partial discharging which exceeds standard is caused by the adoption of traditional phosphor copper welding in the transformer leads and the like are avoided, and the inner structure of the transformer is beautiful in terms of appearance.
Description
Technical field
The utility model relates to a kind of welding transformer lead wire device, belongs to transformer lead jockey technical field.
Background technology
In transformer industry, it is a very important link of transformer manufacturing that lead-in wire connects, and the major way that transformer lead connects before us is the phosphor-copper welding.The professional Welder of phosphor-copper welding needs will go between and be welded to one by one on the coil tap, after welding is finished, also need to carry out the after welding treatment work such as sanding, cleaning, wrapping insulation, the effort of not only taking a lot of work, and welding the time can produce a large amount of heat, can damage insulating part, residual welding slag also is the major reason that causes shelf depreciation.
The utility model content
The purpose of this utility model provides a kind of welding transformer lead wire device, utilizing colds pressing connect finish is connected between winding outlet and the lead-in wire or the winding outlet between connection, thereby the problems referred to above of solution background technology existence.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of welding transformer lead wire device, it is characterized in that comprising cold pressing copper pipe body and hole, and described hole has two, is located at the middle part symmetric position of the copper pipe body of colding pressing.
Described hole is provided with chamfering at the outer wall section of the copper pipe body of colding pressing.
Described two ends of colding pressing the copper pipe body are provided with smooth chamfering.
Also comprise the welding transformer lead wire mould, by forming at the bottom of pressure head, pressure head end and the mould, described pressure head end is provided with smooth end face without the corner angle burr.
The beneficial effects of the utility model are that leader cable of transformer, winding protruding head (circular copper wire, flat type copper wire etc.) are carried out load mould with the cold end terminal of various types and be connected.This connected mode such as has avoided the transformer phosphor-copper welding caused office traditional because lead-in wire adopts to put exceeding standard at the various defectives, and makes in appearance the internal structure of transformer elegant in appearance.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In an embodiment, a kind of welding transformer lead wire device is characterized in that comprising cold pressing copper pipe body 1 and hole 2, and described hole 2 has two, is located at the middle part symmetric position of the copper pipe body 1 of colding pressing.
Described hole is provided with chamfering at the outer wall section of the copper pipe body 1 of colding pressing.
Described two ends of colding pressing the copper pipe body are provided with smooth chamfering 3.
Also comprise the welding transformer lead wire mould, by 6 forming at the bottom of pressure head 4, pressure head end 5 and the mould, described pressure head end 5 is provided with smooth end face without the corner angle burr.
Concrete operation method of the present utility model and detection method for quality:
1, in transformer, except high-voltage connection cable connector (sleeve extracting end) is more suitable for pressing six sides all the other 16～500mm
2Section line (flat type copper wire refers to total cross section) all is fit to cold pressing with the load mould mould, and only presses a hole to get final product;
2, for the wire (such as transposed conductor) that the insulation paint film is arranged, the coating removal film is wanted at the position in entering terminal; Insulating paper layer is arranged, peel turn insulation paper off;
3, the strip conductor width can't inserted terminals greater than terminal diameter, should not take to receive round mode, and should take to select bigger terminal;
4, filling rate should about 90%, must not be lower than 85%; The wire of filling also needs the coating removal film; The interstitial wire inner end should be concordant with wire, and the outer end should enter terminal edge with inner 5mm, must not expose outside the terminal; Interstitial wire allows to fill in peripheral any position; The interstitial wire specification is preferably smaller.See Fig. 3;
5, the terminal sleeve partial-length of selecting should meet following condition (see figure 3):
5.1 the edge in hole must not be less than 10mm apart from the end of a thread edge of terminal edge and insertion;
5.2 satisfying in the above-mentioned condition situation, terminal is short as far as possible;
6, the position of load mould is chosen in wire dress face one side as far as possible, can select other direction when being subjected to performance constraint;
7, during load mould, the indication of prexxure of the hydraulic pump table should at 20～40MPa, need the operator to note observing the crimping process.When operating first, when pressure reaches 20MPa, stop pressurization, the head of colding pressing is checked, if the hole is more shallow and terminal surfaces is flawless, can suitably pressurize again;
8, quality examination
8.1 the position of load mould, the insertion depth of interstitial wire, the insertion depth of wire etc. meets 4 requirement;
8.2 the terminal smooth in appearance without the crimping burr, has allowed a little distortion;
8.3 do not allowed any cracking, the cracking place is arranged, must fill up with the phosphor-copper weldering;
8.4 distortion must not be arranged to the dress face;
8.5 D.C. resistance is qualified.
