CN201946413U - Aluminium wire winded crimped terminal structure of reactor - Google Patents

Abstract

The utility model provides an aluminium wire winded crimped terminal structure of a reactor, which is characterized by comprising an outgoing line which is directly led out by an aluminium winded wire, and a copper plated tin connection terminal is directly pressed on an ultrasonic wave hot dip coating tin part of the outgoing line. The aluminium wire winded crimped terminal structure of the reactor achieves the using performance of crimping the copper outgoing line with the copper connection terminal, therefore, not only the electrical property of the reactor is not reduced, but also electrochemical corrosion in damp air after aluminum bronze is cold welded is prevented.

Description

A kind of aluminum steel coiling crimp type terminal structure of reactor

Technical field

The utility model relates to a kind of aluminum steel coiling crimp type terminal structure of reactor.

Background technology

Transformer and reactor field hold at high price owing to copper material at present, for each manufacturer that reduces production costs adopts aluminium as winding material one after another.

With the reactor of aluminium coiling all is to adopt behind the cold welding copper cash the zinc-plated binding post of crimping copper again.Cold welding process complexity, and cause the not high bad phenomenon of rosin joint, weld strength easily.As shown in Figure 1, there is the situation that adopts the direct crimping copper tip of aluminum steel in the past, connects copper cash 3 in the end of aluminum steel 1 and forms copper aluminium crimping line 2, fills in copper tip 5 then, fills out tin layer 4 at last in the gap.Because it is incomplete to remove the pellumina on aluminium surface, or because alumina speed is too fast, cause producing new rete in the technical process behind the alumina film, make a little less than the adhesive force on tin and aluminium surface, decay resistance is low, causes reactor binding post place contact resistance increase in use.

Summary of the invention

The purpose of this utility model provides the structure of the direct crimping copper tip of aluminum steel that a kind of contact resistance can not increase.

In order to achieve the above object, the technical solution of the utility model has provided a kind of aluminum steel coiling crimp type terminal structure of reactor, it is characterized in that: comprise the lead-out wire of directly being drawn by aluminium coiling line, the zinc-plated binding post of copper directly is compressed on the ultrasonic wave of lead-out wire and wards off on the tin part.

Further, ward off tin at described lead-out wire ultrasonic wave and partly with in the space of the joint of the zinc-plated binding post of described copper be filled with the tin layer.

The utility model reaches the serviceability of copper lead wire and copper tip crimping, does not only reduce the electrical property of reactor, and has prevented the generation of electrochemical corrosion in humid air after the aluminum bronze cold welding.

Embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

As shown in Figure 2, the aluminum steel coiling crimp type terminal structure of a kind of reactor that provides for utility model, comprise the lead-out wire 6 of directly drawing, be provided with ultrasonic wave at the front end of lead-out wire 6 and ward off tin partly 7 that the ultrasonic wave that the zinc-plated binding post 5 of copper directly is compressed on lead-out wire 6 is warded off tin partly on 7 by aluminium coiling line.The ultrasonic wave of lead-out wire 1 ward off tin partly 7 with the space of the joint of the zinc-plated binding post 5 of copper in be filled with tin layer 4.

Manufacturing process of the present utility model is: to aluminium coiling line directly as the leading-out end line processing that degreases; Then leading-out end line is soaked into ultrasonic wave with suitable length and ward off in the tin liquor of fusion in the tin machine tin cylinder, the position is before the ultrasonic amplitude bar; Start ultrasonic wave then, remove pellumina and make tin liquor attached to the aluminum metal surface; At the uniform velocity promote reactor then, make and draw line end and plate uniform tin material.

After adopting technique scheme, follow-up technology is with common reactor exit preparation technology, i.e. the copper tip of tin was plated in crimping, is irritating tin liquor between crimp type terminal and the aluminum steel again, has guaranteed being connected firmly between terminal and the lead-out wire, closely once more.

Claims (2)

1. the aluminum steel coiling crimp type terminal structure of a reactor is characterized in that: comprise the lead-out wire (6) of directly being drawn by aluminium coiling line, the ultrasonic wave that the zinc-plated binding post of copper (5) directly is compressed on lead-out wire (6) is warded off tin partly on (7).

2. the aluminum steel coiling crimp type terminal structure of a kind of reactor as claimed in claim 1 is characterized in that: ward off tin at described lead-out wire (1) ultrasonic wave and partly be filled with tin layer (4) in the space of (2) and the joint of the zinc-plated binding post of described copper (3).
