CN205140705U - Transformer that soldering tin protection was handled - Google Patents

Abstract

The utility model discloses a transformer that soldering tin protection was handled, it includes transformer housing, built -in coil and terminal, and built -in coil is formed by the enameled wire coiling, and the spiral of transformer is connected through soldering tin between enameled wire and the terminal thing for, and the formation protective layer is scribbled or is packed at this soldering tin position by the resin, and this protective layer wraps up outward to be had the sleeve pipe or moulds plastics the shell. The spiral of transformer is connected through soldering tin between enameled wire and the terminal for the thing, in order to reduce soldering tin position extent of corrosion, soldering tin for the position resin paint or fill, for reduce because of external shock to the resin or fill the impaired of position, at soldering tin with the sleeve pipe or the shell protection of moulding plastics after the resin is paintd or is filled for the position.

Description

The transformer of scolding tin conservation treatment

Technical field

The utility model relates to a kind of transformer, particularly relates to a kind of transformer of scolding tin protection part.

Background technology

When transformer spiral thing is connected with terminal with enamelled wire (aluminium wire or copper cash), because of external environment influence, the part of scolding tin is corroded; Or because of external impact, cause enamelled wire and terminal connection part position easily to get loose, how to be connected firmly between enamelled wire and terminal and to become a difficult problem.

Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of transformer of scolding tin conservation treatment.

For solving the problems of the technologies described above; the transformer of scolding tin conservation treatment of the present utility model; it comprises transformer shell, internal coil and terminal; described internal coil is formed by enamelled wire coiling; the spiral thing of transformer is connected by scolding tin with between enamelled wire and terminal; this scolding tin position is smeared by resin or is filled and forms protective layer, and this protective layer is wrapped with sleeve pipe or injection casing.

The enamelled wire material of described transformer spiral thing is aluminium, copper, copper clad steel, copper cover aluminum or aluminium Baogang.

The beneficial effects of the utility model: the spiral thing of transformer is connected by scolding tin with between enamelled wire and terminal; in order to reduce scolding tin position extent of corrosion; scolding tin position resin is smeared or is filled; in order to reduce because external impact is to resin or fill position impaired, protect with sleeve pipe or injection casing after scolding tin position resin is smeared or filled.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the enlarged diagram at A place in Fig. 1.

Fig. 3 is the right view of Fig. 1.

Wherein: 1, enamelled wire, 2, terminal, 3, scolding tin, 4, protective layer, 5, sleeve pipe, 6, transformer shell, 7, internal coil.

Embodiment

In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection range of the present utility model.

As shown in Figure 1, 2, 3; the transformer of the utility model scolding tin protection part; it comprises transformer shell 6, internal coil 7 and terminal 2; internal coil 7 is formed by enamelled wire coiling; the spiral thing of transformer is connected by scolding tin 3 with between enamelled wire 1 and terminal 2; the protective layer 4 that the formation of this scolding tin position is smeared by resin or filled, this protective layer 4 is wrapped with sleeve pipe 5 or injection casing.

Enamelled wire 1 material of transformer spiral thing is aluminium, copper, copper clad steel, copper cover aluminum or aluminium Baogang.

When the aluminium wire of transformer spiral thing or copper cash are connected with terminal; because of external environment condition; the part of scolding tin is corroded; in order to cut off scolding tin position from outside; at scolding tin position, resin is smeared or is filled; scolding tin position is cut off from outside; the scolding tin position of transformer can be protected; even if at this moment scolding tin position is smeared with resin or is filled; also may because of external impact; it is impaired that position is smeared or filled to resin, because external environment condition is likely corroded, with sleeve pipe or injection casing protection resin after scolding tin position resin is smeared or filled.

Claims (2)

1. the transformer of scolding tin conservation treatment; it is characterized in that: it comprises transformer shell, internal coil and terminal; described internal coil is formed by enamelled wire coiling; the spiral thing of transformer is connected by scolding tin with between enamelled wire and terminal; this scolding tin position is smeared by resin or is filled and forms protective layer, and this protective layer is wrapped with sleeve pipe or injection casing.

2. the transformer of scolding tin conservation treatment according to claim 1, is characterized in that: the enamelled wire material of described transformer spiral thing is aluminium, copper, copper clad steel, copper cover aluminum or aluminium Baogang.
