Abstract
The invention discloses a lap-joint type copper-aluminum transition wire clip, which comprises an apparatus clamping part and a lead wire clamping part. The apparatus clamping part and the lead wire clamping part are transited through lap joint, and fixed by welding. The copper-aluminum transition wire clip provided by the invention has the characteristics of simple structure and convenient application. The lap-joint structure substitutes for the conventional butt-joint structure, which effectively increases a copper-aluminum transition area, reduces a transition resistance, and alleviates heat generating phenomenon. Meanwhile, the stress of the wire clip during application is changed, and the mechanical strength of the wire clip is improved. By the adoption of the advanced brazing technique, the welding quality is improved.
Description
Technical field
The present invention relates to the wire clamp of a kind of fixed connection lead and other primary equipments (for example isolating switch), relate in particular to a kind of lap jointing type copper-aluminium transition wire clip.
Background technology
Wire clamp is one of parts very common in the electrical network primary equipment, is mainly bearing the effect of fixed connection lead and other primary equipments (for example isolating switch).The wire clamp that uses at present mainly comprises copper aluminium butt joint wire clamp, fine aluminium/copper cash folder; Because there are shortcomings such as transition resistance is big, easy overheated in fine aluminium/copper cash folder than copper aluminium butt joint wire clamp, the scope of application is relatively littler, and what use mostly is copper aluminium butt joint wire clamp.The copper aluminium butt joint general structure of wire clamp such as Fig. 1, shown in Figure 2; The equipment holder 1 and the wire clamp gripping member 2 that is connected lead 6 that mainly comprise connection device terminal block 4, because the material of equipment terminal block 4 is a copper, the material of lead 6 is an aluminium; Thereby equipment holder 1 is a copper material; Wire clamp gripping member 2 is an aluminium material, docks transition through end face between equipment holder 1 and the wire clamp gripping member 2, and fixes through welding manner; Mainly there is following defective in this structure:
1, because the interim form between equipment holder 1 and the wire clamp gripping member 2 is butt joint, and contact area is little, interface resistance is big, temperature rise is big, be prone to heating;
2,,, therefore can there be risk of breakage at the transition interface place of equipment holder 1 and wire clamp gripping member 2 so the transition interface of equipment holder 1 and wire clamp gripping member 2 is all born pulling force or shearing again because the action of gravity of lead;
3, the transition interface of equipment holder 1 and wire clamp gripping member 2 adopts friction welding (FW) or flash welding mode to carry out the bad mechanical strength of weld more.
In sum; There are shortcomings such as mechanical strength is low in copper aluminium butt joint wire clamp; Fine aluminium/copper cash folder exist transition resistance big, be prone to shortcomings such as overheated, and these shortcomings often expose in the production process of reality, it is overheated even took place wire clamp to bear high temperature, pulling force etc. and the accident of fracture for example to use infrared radiation thermometer just can often measure wire clamp; Especially meeting under the bigger situation of this network load of kurtosis summer, causing very big threat for the safe and stable operation of electrical network.Therefore study the novel wire clamp that a kind of mechanical strength is big, transition resistance is little, will play very positive effect the stable operation of electrical network, the aspects such as reliability of raising electrical network.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of lap jointing type copper-aluminium transition wire clip, improves existing butt joint type copper-aluminium transition wire clip and is prone to heating, defective that mechanical strength is low.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of lap jointing type copper-aluminium transition wire clip comprises equipment holder and wire clamp gripping member, passes through the overlap joint transition between said equipment holder and the wire clamp gripping member, and fixes through welding manner.
Owing to adopted the overlap joint transitional structure, increased contact area, reduced transition resistance, reduced the possibility of generating heat; Overlap transitional structure simultaneously, the shearing action of having avoided transition interface to bear has reduced the transition interface place and has had risk of breakage.Contacted can all be designed to the plane between equipment holder and the wire clamp gripping member, also can be designed to the suitable curved surface of shape, to increase contact area.
Preferably, fixing between said equipment holder and the wire clamp gripping member through the brazing mode welding; This is because soldering processes are advanced, steady quality, is particularly useful for big electric current, heavy in section gold utensil, and just face is bright and clean, air-tightness good for the joint of soldering, shape and size are stable.
In the existing wire clamp; General fixing between general device terminal block and the equipment holder through securing member (such as bolt, nut structure); Owing to adopted the overlap joint transient mode between equipment holder and the wire clamp gripping member; Therefore, can design securing member fastening apparatus terminal block, equipment holder and wire clamp gripping member simultaneously, to improve the mechanical strength of wire clamp.
Beneficial effect: lap jointing type copper-aluminium transition wire clip provided by the invention, simple in structure, easy to use, traditional docking structure is improved as bridging arrangement, effectively increase the copper-aluminium transition area, reduced transition resistance, slowed down the heating phenomenon; Change wire clamp stressed in use simultaneously, improved the mechanical strength of wire clamp; And adopted advanced soldering processes, improved welding quality.
Description of drawings
Fig. 1 for existing wire clamp in use face the sectional structure sketch map;
Fig. 2 is the structural representation of looking up of existing wire clamp;
Fig. 3 for the present invention in use face the sectional structure sketch map;
Fig. 4 is the structural representation of looking up of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As Fig. 3, shown in Figure 4 be a kind of lap jointing type copper-aluminium transition wire clip; The equipment holder 1 and the wire clamp gripping member 2 that is connected lead 6 that comprise connection device terminal block 4; Pass through the overlap joint transition between said equipment holder 1 and the wire clamp gripping member 2, and fixing through the brazing mode welding; Overlap is all the square shape between equipment holder 1 and the wire clamp gripping member 2, during use, passes through securing member 5 mechanical fixation between equipment terminal block 4, equipment holder 1 and the wire clamp gripping member 2.
Compare Fig. 1, Fig. 2, traditional transition interface 3 is merely end face, and the transition interface 3 of Fig. 3, Fig. 4 is the whole upper side of equipment holder 1, area has increased 5 to 7 times.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
