CN203553375U - Novel transition device wire clamp between copper equipment and aluminum equipment - Google Patents

Abstract

This utility model discloses a novel transition device wire clamp between copper equipment and aluminum equipment, mainly comprising an aluminum plate and a copper plate. A projection along the long axis of the aluminum plate is positioned in the center of the axis of the aluminum. Four bolts are installed on the aluminum plate, and every two bolts form a group and are successively arranged on two ends of the aluminum plate along the long axis of the aluminum plate; two ends of the aluminum plate are provided with arc-shaped projections extending out and matching with the bolts; the bolts pass through the aluminum plate from the tops to the bottoms and the lower ends of the bolts are connected to the nuts; gaskets sleeve the bolts; every two bolts arranged along the width axis of the aluminum plate are sleeved by a bonding pad which is positioned between the aluminum plate and the gaskets; and the copper plate are welded with the aluminum plate. The novel transition device wire clamp between copper equipment and aluminum equipment is advantageous in that the segment plated with copper of the aluminum plate is directly replaced with the copper plate so as to guarantee the usage even when abrasion exists because of frictions.

Description

A kind of Novel copper-aluminium equipment transition equipment cable clamp

Technical field

The utility model relates to a kind of Novel copper-aluminium equipment transition equipment cable clamp, a kind ofly specifically can prevent that the phenomenons such as wearing and tearing from use appearring in copper layer and the device that cannot normally use.

Background technology

Device clamp rolls off the production line and is connected with the outlet terminal of electric equipment (as transformer, circuit breaker, instrument transformer, isolating switch, wall bushing etc.) for bus leading.The outlet terminal of now conventional electric equipment has copper and aluminium matter two classes, and lead-out wire mostly is aluminium stranded conductor or steel reinforced aluminium conductor, therefore device clamp is divided into again aluminum equipment wire clamp and two series of copper-aluminium transition equipment cable clamp.According to the installation and application of device clamp, be divided into screw bolt-type device clamp and compression-type device clamp.

Copper aluminium connects can produce electrochemical reaction, increases contact resistance, burns joint, with copper-aluminium transition equipment cable clamp, can avoid this problem.At present, conventional copper-aluminium transition equipment cable clamp on market, what its structure often adopted is on aluminium sheet, to plate layer of copper.Adopt such structure, after long-time use, with layer, tend to, due to former thereby goods wearing and tearing that come off such as frictions, whole copper-aluminium transition equipment cable clamp normally to be worked.

Summary of the invention

The technical problems to be solved in the utility model is to provide and a kind ofly can prevents that the phenomenons such as wearing and tearing from use appearring in copper layer and the Novel copper-aluminium equipment transition equipment cable clamp that cannot normally use.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of Novel copper-aluminium equipment transition equipment cable clamp, and its innovative point is: mainly comprise aluminium sheet and copper coin;

The whole rectangular shape of described aluminium sheet, at the medium position of aluminium sheet, along the long axis direction of aluminium sheet, be provided with an outside outstanding projection, bolt is installed on aluminium sheet, bolt one has four, every two of described bolt is one group, along the long axis direction of aluminium sheet, be successively set on the two ends of aluminium sheet, and four bolts to take the projection at aluminium sheet middle part be the symmetrical setting of line of symmetry, at the two ends of aluminium sheet, be outward extended with respectively the circular-arc projection matching with bolt simultaneously;

Described bolt is from top to bottom through aluminium sheet, and lower end is connected with nut, on each bolt, be also set with pad, described pad is between nut and aluminium sheet, every two bolts along the wide direction of principal axis setting of aluminium sheet are all set with a connection gasket, and described connection gasket is between aluminium sheet and pad, and the length of connection gasket is identical with the width of aluminium sheet, and the two ends of connection gasket are curved shape all, and match with the circular-arc projection of aluminium sheet;

The rectangular shape of described copper coin, and the width of copper coin is identical with the width of aluminium sheet, between described copper coin and aluminium sheet, is welded.

The utility model has the advantage of: will originally directly at copper-plated that section of surface of aluminum plate, directly replace to copper coin, even use after a period of time at device clamp, because friction etc. is former thereby certain wearing and tearing are caused in the surface of copper coin, the inside of its copper coin remains copper, so this device clamp still can be used normally.

Embodiment

Schematic diagram is as shown in Figure 1 known, and Novel copper-aluminium equipment transition equipment cable clamp of the present utility model mainly comprises and mainly comprises aluminium sheet 2 and copper coin 5.

Schematic diagram is as shown in Figure 2 known, the whole rectangular shape of aluminium sheet 2, at the medium position of aluminium sheet 2, along the long axis direction of aluminium sheet 2, be provided with an outside outstanding projection 6, bolt 7 is installed on aluminium sheet 2, bolt 7 one has four, every two of bolt 7 is one group, along the long axis direction of aluminium sheet 2, be successively set on the two ends of aluminium sheet 2, and it is the symmetrical setting of line of symmetry that four bolts 7 be take the projection 6 at aluminium sheet 2 middle parts, at the two ends of aluminium sheet 2, be outward extended with respectively the circular-arc projection matching with bolt 7, thereby facilitate the installation of bolt 7 simultaneously.

Bolt 7 is from top to bottom through aluminium sheet 2, and the lower end of bolt 7 is connected with nut 1, on each bolt 7, be also set with pad 3, pad 3 is circular, pad 3, between nut 1 and aluminium sheet 2, is all set with a connection gasket 4 on every two bolts 7 of the wide direction of principal axis setting of aluminium sheet 2.

Schematic diagram is as shown in Figure 3 known, connection gasket 4 is between aluminium sheet 2 and pad 3, the length of connection gasket 4 is identical with the width of aluminium sheet 2, and the equal curved shape in the two ends of connection gasket 4, and the two ends of the arc shape of connection gasket 4 all match with the circular-arc projection that extend at the two ends of aluminium sheet 2.

The rectangular shape of copper coin 5, and the width of copper coin 5 is identical with the width of aluminium sheet 2, between copper coin 5 and aluminium sheet 2, is welded.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
