Description
Technical field
The utility model relates to the reactor field, is specifically related to a kind of copper aluminium crimping syndeton that is used for reactor.
Background technology
The copper aluminium crimping syndeton that is used for reactor at present generally comprises two kinds of forms, and a kind of copper aluminium crimping syndeton that is used for reactor is direct compression joint type, and another kind is a welded type.
As depicted in figs. 1 and 2; Directly compression joint type copper aluminium crimping syndeton comprises aluminum steel 1 and tin-coated copper terminal 2; The cross section of aluminum steel 1 is a rectangle, and the end of tin-coated copper terminal 2 is provided with the sleeve 21 that is used for crimping aluminum steel 1, and aluminum steel 1 is located in the sleeve 21 and is directly used the Crimping Pliers crimping.Because tin-coated copper terminal 2 terminal sleeves 21 are round; And the aluminum steel 1 of reactor winding is flat rectangular-shaped cross section, after letting aluminum steel 1 fill in sleeve 21 to carry out crimping, between aluminum steel 1 and the sleeve 21 very big slit must be arranged; On the one hand because the slit can cause the out-of-shape of sleeve 21 outward appearances; Very ugly, the slit can cause tin-coated copper terminal 2 not contact fully with aluminum steel 1 on the other hand, and humid air is easy to into the slit; Time has been grown and has caused the aluminum steel 1 and the place of tin-coated copper terminal 2 crimping to produce electrochemical corrosion, causes heating to burn out copper aluminium crimping syndeton easily.
Like Fig. 3 and shown in Figure 4; Connect formula copper aluminium crimping syndeton and comprise aluminum steel 1 and tin-coated copper terminal 2, the cross section of aluminum steel 1 is a rectangle, and the end of tin-coated copper terminal 2 is provided with the sleeve 21 that is used to hold aluminum steel 1; Aluminum steel 1 is located at still not crimping in the sleeve 21; But directly use the aluminum steel special welding wire, high temperature melting is tamped the space between aluminum steel 1 and the sleeve 21, and aluminum steel 1 and tin-coated copper terminal 2 are welded.This kind way, to this piece of aluminum bronze electrochemical corrosion, fine certainly.And contact also firm.But because sleeve 21 be circular, so the slit between aluminum steel 1 and the tin-coated copper terminal 2 is big really, if will tamp with aluminium welding wire, and the shortcoming of have spended time length, joint efficiency is extremely low, cost is expensive, wasting aluminium welding wire.
The utility model content
The technical problem that the utility model will solve provides and a kind ofly can prevent electrochemical corrosion, the copper aluminium crimping syndeton that is used for reactor that cost is low, joint efficiency is high, appearance looks elegant is generous.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of copper aluminium crimping syndeton that is used for reactor; Comprise aluminum steel and tin-coated copper terminal, the cross section of said aluminum steel is a rectangle, and the end of said tin-coated copper terminal is provided with sleeve; Said aluminum steel crimping is fixed in the said sleeve, is provided with the thread filler of aluminium scrap between said aluminum steel and the sleeve.
Further improvement as technique scheme:
The cross section of said sleeve is a hexagon.
The end of said sleeve is provided with weld part, and said weld part is welded to connect with said aluminum steel, sleeve respectively.
The utlity model has following advantage:.
1, is provided with the thread filler of aluminium scrap between aluminum steel of the utility model and the sleeve; Can make full use of and produce the aluminium scrap line that reactor winding is cut at ordinary times; In the slit through the tin-coated copper terminal before filler directly being filled up aluminum steel and not pressing; It is long-pending to increase conductive contact surfaces, and contact performance is good, has to prevent electrochemical corrosion, the advantage that cost is low, joint efficiency is high.
2, the cross section of the utility model sleeve further is a hexagon, and the crimping contact between aluminum steel and the tin-coated copper terminal is more solid and reliable, and appearance looks elegant is generous.
3, the end of the utility model sleeve further is provided with weld part; Weld part is welded to connect with said aluminum steel, sleeve respectively; Get final product with aluminum steel crimping edge joint weld one circle along copper tip is terminal with the aluminum steel special welding wire; Can guarantee that the contact between aluminum steel and the tin-coated copper terminal is more reliable on the one hand, mechanically stressed performance is better; Aluminium welding wire can also be saved on the other hand, the welding efficiency between aluminum steel and the tin-coated copper terminal can be improved.
