Abstract
The utility model discloses a kind of jumper clamp, including two drainage terminal boards, one end of two drainage terminal boards is equipped with the connection plate face mutually overlapped and is bolted, and the other end of two drainage terminal boards is tubulose；The positioning protrusion and positioning groove of mutual cooperation are respectively equipped with connection plate face between two drainage terminal boards；Insulating boot is equipped with outside connection plate face between two drainage terminal boards, insulating boot can pass through tightening of rivet by a side opening folding and after closing, insulating boot covers on the bolt wherein, and rectangle gap is respectively equipped with insulating boot both ends, for the connection plate face through two drainage terminal boards.Beneficial effect is：Not only make connection more firm, avoid and mutually rotate, and increase the contact surface area between the connection plate face between two drainage terminal boards, reduce resistance, save electric energy；Insulating boot covers on bolt wherein, can avoid, because bolt point discharge produces corona phenomenon, further saving electric energy.
Description
Technical field
A kind of electric armour clamp is the utility model is related to, more particularly to a kind of jumper clamp.
Background technology
Existing jumper clamp product is fastened after the drainage terminal board drilling for two hydraulic test wire clamps by bolt to be coupled
The conducting connecting part of composition, the joint face of the jumper clamp couple for plane, due to product after the operation of jumper clamp connecting conducting wire
Itself heat can be produced, expansion or shrinkage makes easily to loosen between the contact surface of two drainage terminal boards, especially runs into air quantity swing
When, make the contact of jumper clamp terminal conjunction plane not tight, cause resistance to increase, cause supply line's electricity heavy losses.
It can discharge further, since the bolt tip of two drainage terminal boards of connection is exposed in air and produce corona and show
As, therefore add the loss of electric energy.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, is connected firmly, can avoid because of spiral shell
Bolt point discharge and produce corona phenomenon, save the jumper clamp of electric energy.
To solve the above problems, the utility model adopts the following technical solution：
A kind of jumper clamp, including two drainage terminal boards, one end of two drainage terminal boards are equipped with the company mutually overlapped
Fishplate bar face is simultaneously bolted, and the other end of two drainage terminal boards is tubulose, for connecting wire；It is characterized in that：
The positioning protrusion and positioning groove of mutual cooperation are respectively equipped with connection plate face between two drainage terminal boards；Draw at two
Insulating boot is equipped with outside connection plate face between stream terminal board, insulating boot can be by tight by rivet after a side opening folding and closure
Gu insulating boot covers on the bolt wherein, rectangle gap is respectively equipped with insulating boot both ends, for draining terminals through two
The connection plate face of plate.
As further preferred, width and the width gaps of the connection plate face in the middle part of the insulating boot inner cavity coordinate,
The width of insulating boot inner cavity upper and lower part is less than the width in the middle part of inner cavity and coordinates with the stub end of bolt and nut, exhausted to improve
The intensity of edge cover.
As further preferred, the rectangle that the positioning protrusion includes a circle closing is convex stupefied, in the convex stupefied area surrounded of rectangle
Transversely it is equipped with that multiple orthogonal bar shapeds are convex stupefied, and the bolt is two and to be distributed in the rectangle convex stupefied in domain with longitudinal direction
In the region surrounded.
As further preferred, the rectangle is convex stupefied and the convex stupefied cross section of bar shaped is triangle.
As further preferred, the convex stupefied longitudinally arranged quantity of bar shaped is two.
The beneficial effects of the utility model are：
1st, due to being respectively equipped with the positioning protrusion of mutual cooperation in the connection plate face between two drainage terminal boards and determining
Position groove, not only makes connection more firm, avoids and mutually rotate, and increase the company between two drainage terminal boards
Contact surface area between fishplate bar face, reduces resistance, saves electric energy.
2nd, due to being equipped with insulating boot outside the connection plate face between two drainage terminal boards, insulating boot is by the bolt cover
Wherein, can avoid, because bolt point discharge produces corona phenomenon, further saving electric energy；Not only avoid bolt life
Rust, and extend the service life of jumper clamp.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the A-A cutaway view Amplified images of Fig. 1.
Fig. 3 is provided with the structure diagram of the drainage terminal board of positioning protrusion.
