Abstract
The utility model relates to a cable clamp in a field of electro-technology and specially relates to a copper-aluminum parallel cable clamp. The copper-aluminum parallel cable clamp includes an upper press cover and an oppositely arranged lower press cover disposed below the upper press cover. A bolt first penetrates through the upper press cover and the lower press cover successively from top down and then connects with a nut having a spring gasket. The right sections and the left sections of the upper press cover and the lower press cover are copper and aluminum respectively. The left ends and the right ends of the upper press cover and the lower press cover are provided with semicircular grooves respectively. The semicircular grooves in the right sections of the upper press cover and the lower press cover arranged oppositely are used for clamping a copper lead while the semicircular grooves in the left sections of the upper press cover and the lower press cover arranged oppositely are used for clamping an aluminum lead. In the utility model, the copper part groove in the copper-aluminum parallel cable clamp contacts with the copper lead while the aluminum part groove in the copper-aluminum parallel cable clamp contacts with the aluminum lead, thereby satisfying special requirements of a prior parallel cable clamp. At the same time, the copper-aluminum parallel cable clamp also meets state technical requirements of copper and aluminum transition connection products specified by a power grid.

Technical field
The utility model relates to the wire clamp of electrical technology field, is a kind of copper-aluminium combination groove wire clamp specifically.
Background technology
Copper cash all is to adopt the parallel groove clamp that is formed by aluminum profile extrusion with excessive connection of aluminum steel in the present empty frame power circuit.Adopt this parallel groove clamp that is formed by aluminum profile extrusion, copper conductor directly places in the groove that is formed by aluminum profile extrusion, except producing the creep disastrous effect because of oxide-film and aluminium; Also can further increase because of the rotten turbid contact place contact resistance that causes of the electrification between aluminium, copper, this is that the two in a humid environment because of the electrode potential of aluminium and differing greatly of copper; Special in the wet environment of salt is arranged, can form the micro cell of potential difference, it is turbid and contact is damaged by corruption very soon that aluminium can lose electronics; Make electric current in running; Contact is smoldered, and puts phenomenons such as quick-fried, and produces power outage thus or cause fire.
The utility model content
To the defective that exists in the prior art; The purpose of the utility model is to provide a kind of copper-aluminium combination groove wire clamp; Copper portion groove on the wire clamp contacts with copper conductor; Aluminium portion groove contacts with aluminum conductor, to satisfy the various special requirements of existing parallel groove clamp, can also satisfy the Technology Need of country to the excessive product of copper aluminium of electrical network regulation simultaneously.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of copper-aluminium combination groove wire clamp is characterized in that, comprising: after the upper press cover 1 that is oppositely arranged up and down, lower cover 2, bolt 3 penetrate upper press cover 1, lower cover 2 from top to bottom successively, be connected with the nut 5 of band spring shim 4,
The right section 11 of said upper press cover 1, lower cover 2 and the material of left side section 12 are respectively copper and aluminium,
The right ends of upper press cover 1, lower cover 2 is respectively equipped with semi-circular groove,
The semi-circular groove of the right section 11 of upper press cover 1, lower cover 2 is used for clamping copper conductor 21 up and down relatively, and the semi-circular groove of the left side section 12 of upper press cover 1, lower cover 2 is used for clamping aluminum conductor 22 up and down relatively.
On the basis of technique scheme, between the outer surface of upper press cover 1 and bolt 3, be provided with pressing plate 6, between the outer surface of band spring shim 4 and lower cover 2, be provided with pad 7.
On the basis of technique scheme, be provided with some teeth at the inner surface of semi-circular groove, the end of said teeth is a cambered surface.
The described copper-aluminium combination groove wire clamp of the utility model; Copper portion groove on the wire clamp contacts with copper conductor; Aluminium portion groove contacts with aluminum conductor, to satisfy the various special requirements of existing parallel groove clamp, can also satisfy the Technology Need of country to the excessive product of copper aluminium of electrical network regulation simultaneously.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 the utility model assembly structure sketch map,
The left TV structure sketch map in Fig. 2 the utility model product assembling back.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Like Fig. 1, shown in 2, the described copper-aluminium combination groove wire clamp of the utility model comprises:
After the upper press cover 1 that is oppositely arranged up and down, lower cover 2, bolt 3 penetrate upper press cover 1, lower cover 2 from top to bottom successively, be connected with the nut 5 of band spring shim 4,
The right section 11 of said upper press cover 1, lower cover 2 and the material of left side section 12 are respectively copper and aluminium, and for example: can two kinds of materials of copper and aluminium be welded through the flash method, copper can be selected copper T2 for use, and aluminium can aluminium 1050A,
The right ends of upper press cover 1, lower cover 2 is respectively equipped with semi-circular groove,
The semi-circular groove of the right section 11 of upper press cover 1, lower cover 2 is used for clamping copper conductor 21 up and down relatively, and the semi-circular groove of the left side section 12 of upper press cover 1, lower cover 2 is used for clamping aluminum conductor 22 up and down relatively.
On the basis of technique scheme, between the outer surface of upper press cover 1 and bolt 3, be provided with pressing plate 6, between the outer surface of band spring shim 4 and lower cover 2, be provided with pad 7.It is firm that its purpose is to increase the connection of guaranteeing upper press cover 1, lower cover 2, increases the useful life of upper press cover 1, lower cover 2.
On the basis of technique scheme, be provided with some teeth at the inner surface of semi-circular groove, the end of said teeth is a cambered surface.Its purpose is to increase the clamping dynamics to lead.
Compared with prior art, this novelly has a following advantage:
1, owing to adopted the copper-aluminium combination groove wire clamp, makes that the copper portion groove (copper conductor clamping slot 21) on the wire clamp contacts with copper conductor; Aluminium portion groove (aluminum conductor clamping slot 22) contacts with aluminum conductor, has avoided outside the creep disastrous effect because of oxide-film and aluminium, and dependability is high.
2, owing to adopted low resistance, the high purity alloys of high anti-rotten turbid ability is done copper aluminium excess material, makes the power delivery performance good, good electric property, and also anti-rotten turbid ability is strong.
3, because of having adopted the flash method to be welded, make the solder side mechanical strength good, safe and reliable, and suitable antistripping ability is arranged.
4, processing technology is simple, and cost is low, and the market competitiveness is strong.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection range of the utility model.
