Abstract
The utility model relates to a two-plate type strain clamp, wherein an aluminum tube is welded with a two-plate drainage device; a drainage plate is connected with the aluminum plate via groove welding; and the groove end parts of the two plates are provided with a small groove, thereby reducing the weight of the clamp, reducing strain concentration, improving current contact area, preventing bad contact and overheat condition caused by single-face contact, improving contact strength to resolve the breakage caused by low welding strength of lower drainage plate, and resolving the high weight problem of the strain clamp which adopts the drainage tube of branch extension structure. The aluminum tube and the two drainage plates of the strain clamp are in one plane, to improve the bearing ability of the two drainage plates and make the strain clamp firm and durable.
Description
Affiliated technical field
The utility model relates to a kind of electric armour clamp, relates in particular to a kind of lead to be connected double-plate strain clamp on the insulator string.
Background technology
General its drainage plate of strain clamp is that single face contacts with drainage tube at present; promptly on the strain clamp body, only be provided with a drainage plate that extends in the form of sheets; and the drainage tube that cooperates an end also to extend in the form of sheets form sticking touch sealed; so have only the bonding contact of area of single face; thereby the time regular meeting take place to cause because of drainage plate and drainage tube loose contact or contact-making surface are too little overheated, even with drainage plate and the red phenomenon of drainage tube burning.The traditional drainage plate is generally all by the argon arc welding, and this occurs producing the phenomenon of fracture because of insufficient strength easily.Therefore known one-board strain clamp current stability is poor, and security performance is not high
The patent No. is 200420115280.2 to have announced a kind of " crimping and tension-resisting clip ", this utility model has been improved the drainage plate solder technology of above-mentioned traditional strain clamp, the steadiness that makes it more traditional strain clamp increases, but still there is defective in the Al pipe butt welding orientation of its drainage plate and strain clamp body, owing to adopt the azimuth design of the aluminum pipe of strain clamp perpendicular to the drainage plate plane, when straining, the drainage tube load-bearing can apply export-oriented component respectively perpendicular to two drainage plate planes, thereby must make two drainage plate spacings strengthen after for a long time stressed and produce slits, and this slit is prone to corona, thereby causes that electrical potential difference produces electric discharge phenomena.
The utility model content
Problem to be solved in the utility model is: a kind of double-plate strain clamp is provided, makes it can increase the electric current contact area, and firm and durable, simple in structure, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double-plate strain clamp, it is made up of wire clip body aluminum pipe (1), steel anchor (2), the two plates (3) of drainage, drainage tube (4), drainage tube veneer (6), bolt (5), it is characterized in that: on aluminum pipe (1), welded the two plates (3) of a drainage, adopt the mode of cut welding that the two plates of drainage are connected with aluminum pipe, a technology groove (9) has been opened in groove end at the two plates (3) of drainage, this technology groove can alleviate wire clamp weight, reduces stress and concentrates; Adopt the two plates of strain clamp body aluminum pipe and drainage in conplane azimuth design, can not produce export-oriented component when so just making drainage tube load-bearing tension to the two plates of drainage, thereby solve the problem that occurs the slit between drainage plate and the drainage tube, increased the bonding area of two plates of drainage and body aluminum pipe simultaneously, make the two plate load-bearing of drainage increase the strain clamp firm and durable.
The utility model has increased the electric current contact area, prevent because of too small loose contact that causes of electric current contact-making surface and superheating phenomenon, also improve and be subjected to force intensity, solve the not enough and crack conditions that produces of drainage plate weld strength generally, can also solve the strain clamp weight problem bigger than normal of the drainage tube that has adopted the bifurcated extended structure.
The utility model
Compared with prior art, advantage of the present utility model is:
1, is welded with the two plates of drainage on the wire clip body, so both increased the electric current contact area, improved the stability of cross section electric current.
2, adopt two plates of drainage and wire clip body aluminum pipe in conplane azimuth design, to the vertical export-oriented component of the two plates of drainage, also solved the problem that the slit appears in two plates of drainage and drainage tube veneer in the time of both can eliminating the drainage tube load-bearing.
3, increase the contact area of two plates of drainage and wire clip body aluminum pipe, increased the weight capacity of the two plates of drainage.
4, open a technology groove in the groove end of two plates, alleviate wire clamp weight, reduce stress and concentrate.
5, adopt welded structure can also save material, weight reduction, thus reduce cost, and, contact strength is improved because two plate connects, security performance is improved.

Embodiment
Following conjunction with figs. 1 describes embodiment of the present utility model in detail with Fig. 2: lead is passed strain clamp body aluminum pipe (1) penetrate in the steel anchor leading portion blind pipe (7), carry out crimping and fix.Then the steel anchor is receded in the body steel pipe, carry out crimping at steel anchor ring flank (8) and body aluminum pipe.Pierce into the body aluminum pipe end that enters the mouth at lead subsequently lead and aluminum pipe are carried out crimping.Also lead is penetrated at drainage tube (4) one ends, carry out crimping and fix.Next drainage tube veneer (6) is embedded in two plate (3) grooves (9) of drainage, with four bolts (5) drainage pair plates are tightened with veneer and be connected.At last whole pair of plate strain clamp is fixed on the insulator with steel anchor (2).
Claims (3)
1, a kind of double-plate strain clamp, form by wire clip body aluminum pipe (1), steel anchor (2), the two plates (3) of drainage, drainage tube (4), drainage tube veneer (6), bolt (5), it is characterized in that: on aluminum pipe (1), welded the two plates (3) of a drainage, adopted the mode of cut welding that the two plates of drainage are connected with aluminum pipe.
2, a kind of double-plate strain clamp according to claim 1 is characterized in that: a technology groove (9) is opened in the groove end at the two plates (3) of drainage.
3, a kind of double-plate strain clamp according to claim 1 is characterized in that: adopt two plates of drainage and wire clip body aluminum pipe in conplane azimuth design.
