Description

Bimetallic connector

The present invention relates to a kind of bimetallic connector that is used for ground connection and connects electricity.It comprises a copper spare and an aluminum component.Copper spare links to each other, and extends round about from the junction with copper-Al bimetal combination with aluminum component.The junction is positioned at one and is suitable for by on the intermediate of electric connection clamping device clamping.One first guide plate is arranged on the aluminum component, one second guide plate is arranged on the copper spare.

When being connected with ground, when especially particularly this type of joint was used for being connected with lightning arrester, the copper spare of an existing bimetallic connector and aluminum component comprised opposite semi-circular ends.In the field of employment, a vertical plane as wall is often arranged.Existing electric connection is clamped by a clip that is clipped on its intermediate.Like this, the curved surface of each end is all adjoining with vertical plane, therefore, does not obviously have to utilize the space between electric connection and perpendicular walls, thereby can not put into nut or head of screw.This just means, must have some to pierce on the existing electric connection and screw that hold-down screw is used, and screw also passes corresponding copper coin bar and aluminium strip simultaneously.

The objective of the invention is to overcome the defective of existing electric connection.

The realization of this purpose reaches by following technical solution: a kind of bimetallic connector that is used to connect electricity and ground connection, comprise an aluminum component and a copper spare that combines by copper-Al bimetal combination, aluminum component and copper spare extend round about from binding site, and are arranged on the intermediate that is suitable for the clamping of joint clamping device; One first guide plate is arranged on the aluminum component, one second guide plate is arranged on the copper spare, it is characterized in that, for described first guide plate: (a) it has occupied the wide zone of a basic axial alignment; (b) it has two relative substantially parallel planes, and the thickness that they form is less than the thickness of described intermediate; (c) it has a through hole at least, extends between the described opposite planar.

Because first guide plate of electric connection of the present invention is centering and thinner than the middle part, therefore when electric connection is mounted, must have a free space in the first guide plate back.This free space allows head of screw or nut to be loaded into.Because like this, being connected of first guide plate and aluminum strip just there is no need to use screw thread, the also available standardized element that obtains easily, and as screw, nut, and shimming when needing.It should be noted that we think that with screw, nut and pad be a kind of connection in the most reliable.

Be characterised in that for preferred second guide plate of the present invention: it is offset to central shaft basically.It has two relative planes, with the relative plane parallel of described first guide plate, and stretches have a hole at least between these two relative planes.

Because this feature, for electric connection of the present invention, it is possible using the copper guide plate of the existing forging that is easy to get.

Above-mentioned second guide plate also can be selected another kind of feature for use: it is axial alignment basically.Because like this, just can use the copper guide plate of other and aluminium guide plate similar manner.

In the explanation that further advantage of the present invention and feature will be embodied in reference to the accompanying drawings to be done.Be the not most preferred embodiment of arrowhead of the present invention below:

Fig. 1 is the stereogram of an embodiment of electric connection of the present invention.

Fig. 2 is the end view of a minification.

Fig. 3 also is the vertical view of a minification.

Fig. 4 is the stereogram of second embodiment of electric connection.

Fig. 5 is the end view of second enforcement of minification.

Fig. 6 also is the vertical view of second embodiment of minification.

Bimetallic connector comprises a copper spare 2 and an aluminum component 4.They are to be linked together by friction welding (FW) or other mode that can form copper-Al bimetal combination.This bound fraction can be by line 6 expressions.Part 2 and 4 is from line 6 each extension in the opposite direction.Binding site is positioned on the preferably cylindrical or prismatic intermediate 8, has so just determined its bus.The pattern of intermediate 8 and thickness make it be fit to be held the device clamping.This clamping device is a standard circlip (not drawing among the figure) preferably.

Preferably intermediate 8 makes described clip be loaded onto easily and be positioned on securely on its position between two extensions 10.And the bus that in fact side 12 of each extension 10 is preferably in intermediate meets at right angles.

There is one to be used for first guide plate 14 that is connected with a slat (figure does not draw) on the aluminum component 4.Slat is generally with aluminium, also can make with some other material.First guide plate 14 has two relative parallel surfaces 16, and the distance between them is basically less than the thickness of intermediate, therefore also less than the diameter of extension 10.So, between a plane 16 and corresponding extension 10 extending part farthest, have one hereinafter with the space of mentioning.First guide plate 14 is axial alignment basically, and promptly two height 18 shown in Fig. 2 equate basically.Also have at least one to extend two through holes 20 between the plane 16 on the guide plate 14, to be fit to insert screw, pin, nut or other similar part.

Secondly, also there is one to be used for second guide plate 22 that is connected with a slat on the copper spare 2.Slat is generally with copper, also can make with some other material.Slat does not draw equally in the drawings.Also have on second guide plate two relative be flat plane 24 basically, the surface 16 of they and first guide plate 14 is parallel basically.In Fig. 1 to Fig. 3, as can be seen, second guide plate 22 is offset to central shaft, as some known forging guide plates.In this described embodiment, extending has a hole 26 as through hole 20 between the described opposite planar, to be fit to insert screw, pin, nut or other like parts.

When this electric connection with a clip when a vertical plane as wall or pole is installed, the outline of first guide plate 14 and can be made by each 16 formed described space, surface and to insert a nut or head of screw so just makes the use of electric connection very easy.

In the embodiment of Fig. 4 to Fig. 6, aluminium guide plate 4 and intermediate 8 have one and the practically identical shape of embodiment narrated.Different is that copper guide plate 22 is centering basically, and is similar with the mode of aluminium guide plate 14.Therefore in this case, two height 28 shown in Fig. 5 equate basically.Here, there is no need to do further clear and definite explanation to Fig. 4 to Fig. 6 and to the part similar to the embodiment of first three figure.

It is pointed out that electric connection of the present invention also can be used between aluminium and the copper cable and the bimetallic of bus terminal connects.
