Abstract
The utility model relates to a connecting device between the conductive rod of the switching device and a directing line. The connecting device between the conductive rod of the switching device and a directing line is composed of an aluminum press bottom board (1), an aluminum press board (2), the connecting sleeve of the conductive bar (3), and screw bolts (4). The external side of the connecting sleeve of the conductive bar (3) is an aluminum casing (5), and the internal side is the internal sleeve of the copper tube (6). The connecting device between the conductive rod of the switching device and a directing line has the characteristics of saved copper materials, large contact area of the copper and the aluminum, tight connection, etc., and the connecting device between the conductive rod of the switching device and a directing line can avoid the problems of the galvanic corrosion of the copper and the aluminum, resistance increase, and temperature increase.
Description
The utility model is a kind of electric apparatus connector, promptly a kind of tubular type copper-aluminium transition binding post.
Finish with the jockeys such as adopting wire clamp that is connected of lead at controller switching equipment more, present jockey exists more and controller switching equipment conducting rod contact area is little and copper aluminium between the junction produce harmful phenomenons such as couple corrosion.I once proposed casting formula copper-aluminium transition method (number of patent application 94120049.3), made between the copper aluminium and can closely connect, and had avoided the problem of couple corrosion.Adopt the wire clamp of this method manufacturing, the copper sheathing that it combines with the equipment conducting rod and the aluminium sheet bonded area of wire clamp are less, thereby have wasted copper material, and be not tight with combining of aluminium.
The purpose of this utility model is a kind of saving copper material of development, and copper aluminium contact area is bigger, in conjunction with wiring equipment more closely.
Above-mentioned purpose is realized by following technical scheme: this binding post also is made up of aluminium pressing plate, aluminium pressing plate and conducting rod adapter sleeve and bolt, and different is that said conducting rod adapter sleeve is made up of cover in aluminium overcoat and the copper pipe.
Cover and aluminium overcoat can be cast and connect as a wholely in the copper pipe, and a transition zone is arranged on the copper aluminium contact-making surface.
Said transition zone can be the galvanizing layer.
Said transition zone can be the wicking layer.
The cover internal diameter can be provided with the screw thread that matches with conducting rod in the said copper pipe.
Said conducting rod adapter sleeve one side can be provided with the opening of regulating internal diameter.
The binding post that adopts such scheme to make, save the copper material, and, contact area is big between copper pipe and the aluminium overcoat, is issued in the transition zone effect to connect closely, thereby has avoided couple corrosion and increased the problem that resistance heats, particularly because few with copper, the copper pipe small body and thin wall has a narrow range of temperature when casting with aluminium, very easily combination.
Introduce an embodiment below in conjunction with accompanying drawing.
Fig. 1 is the front view of present embodiment, and Fig. 2, Fig. 3 are respectively two partial views.
As seen from Figure 1, this binding post is made up of aluminium press 1, aluminium pressing plate 2 and conducting rod adapter sleeve 3 and screw rod 4, conducting rod adapter sleeve 3 is made up of cover 6 in aluminium overcoat 5 and the copper pipe, aluminium overcoat 5 and aluminium press 1 are an integral body that casts out, during casting, earlier cover 6 in the copper pipe of galvanizing or tinning processing is placed the assigned address of mould, and then injection aluminium water, between copper aluminium, form a transition zone 8, behind the shaping and demoulding, side at conducting rod adapter sleeve 3 is sawed out opening 9, gets screw 7 in opening 9 both sides again.This binding post, between aluminium press 1 and the aluminium pressing plate 2, but the crimping aluminum conductor, conducting rod adapter sleeve 3 can be used for conductive pole and connects.Threads engaged on threaded and the conducting rod in the cover 6 during use, is installed in earlier on the conducting rod in the copper pipe of adapter sleeve 3 the insides of conducting rod adapter sleeve 3 the insides, penetrates screw 7 with bolt again and tightens, and can hold tightly with conducting rod.
Claims (6)
