Abstract
The utility model provides a drop-off prevention electrified line clamp. The upper end of a clamp body is a fixed lead end; a base is arranged below the clamp body; a screw hole is formed in the base; a screw is installed inside the screw hole; a slide block is arranged below the fixed lead end; the back of the slide block is in slide connection with the surface of the clamp body vertically; the upper part of the slide block is a trapezoid-shaped plane; a circular hole is formed in the bottom plane of the slide block; the upper part of the screw stretches into the hole; an annular groove is formed in the rod wall of the upper part of the screw; screw holes are formed at two sides of a circular hole at the bottom of the slide block respectively; clamping bolts are screwed inside the screw holes respectively; the clamping bolts correspond to the annular grooves at the upper part of the screw; a screw hole is formed at the front plane of the slide block and a fixing bolt is screwed into the screw hole; and a lead terminal is installed below the clamp body. According to the drop-off prevention electrified line clamp, as the fixing bolt is adopted, the screw is effectively fixed, so that the line clamp and the lead are fixed more firmly and unlikely to drop off. As the slide block of the drop-off prevention electrified line clamp is provided with a trapezoid-shaped groove and the fixed lead end at the upper part of the clamp body is an arced groove, the line clamp can clamp the lead more firmly, and the contact area is larger, so that poor contact between the line clamp and the lead is prevented.
Description
Technical field
The utility model relates to a kind of power circuit lead-in wire T and connects and use hot line clamp, and particularly a kind of slip-off preventing hot line clamp goes between when being mainly used in the 10kV distribution line live working and the connecting of backbone.
Background technology
Existing technology is after screw rod is screwed in the lower end threaded hole of clamp, along with the rotation of screw rod, promotes slide block and makes linear running up and down, realizes the purpose that clamps, unclamps lead.
Prior art can compress easily and unclamp lead, but lead is when compressing, and is fastening not firm, and wire clamp because effects such as lead vibrations, swing make screw rod generation counter-rotating, causes wire clamp to get loose when operation, influences electric power and reliably supplies.Simultaneously, the clamp groove of wire clamp can not fully contact with lead, and loaded current is little, and long-play burns wire clamp easily, influences electric power and reliably supplies.
Summary of the invention
The purpose of the utility model provides and a kind ofly can prevent that screw rod is loosening and cause wire clamp to come off, and wire clamp can be fastened on the lead, can carry the easy installation hot line clamp of big electric current simultaneously.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of slip-off preventing hot line clamp comprises: clamp, the upper end of clamp are the fixing cord end, and the bottom of clamp has seat, have screw on the seat, and screw rod is housed in the screw; It is characterized in that: below the fixing cord end of clamp, be provided with slide block, the back side of slide block and clamp vertical surface are slidingly connected; The top of slide block is trapezoidal faces, and the bottom surface of slide block has the circular hole that is complementary with said screw diameter, and the top of screw rod is stretched in the hole; The upper bar wall of screw rod is provided with a cannelure; The both sides of slide block bottom surface circular hole respectively have a screw, respectively are rotary with the screens bolt in the screw, and the screens bolt is corresponding with the cannelure on the top of screw rod; The front of slide block has a screwed hole, is rotary with gim peg in the screwed hole; The bottom of clamp is equipped with lead terminal.
The utility model slip-off preventing hot line clamp was compared with former hot line clamp:
1, the utility model slip-off preventing hot line clamp has adopted gim peg, and it is fixing that screw rod has been obtained, thereby makes the fixing more firm of wire clamp and lead, difficult drop-off.
2, on the movable slider of the utility model slip-off preventing hot line clamp dovetail groove is arranged, the top fixing cord end of clamp is an arc groove, and the lead of wire clamp clamping is more firm, and contact-making surface is bigger, has prevented that wire clamp and lead from producing loose contact.
3, the lead end of the utility model slip-off preventing hot line clamp has adopted lead terminal, uses the crimping mode to make lead-in wire more firm with contacting of wire clamp, and the situation that has also reduced loose contact takes place.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left TV structure sketch map of the utility model.
In the accompanying drawing: 1, screw rod; 2, screens bolt; 3, gim peg; 4, slide block; 5, fixing cord end; 6, the trapezoidal faces on slide block top; 7, clamp; 8, cannelure; 9, lead terminal.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
The utility model slip-off preventing hot line clamp such as Fig. 1, shown in Figure 2 comprise: clamp 7, the upper end of clamp 7 are fixing cord end 5, and the faces that contact with lead below the fixing cord end 5 are arc surface, and the radius of the radius of circular arc and folded heavy gauge wire adapts.The bottom of clamp 7 has seat, has screw on the seat, and screw rod 1 is housed in the screw.Below the fixing cord end 5 of clamp 7, be provided with slide block 4, the vertical surface of the back side of slide block 4 and clamp 7 is slidingly connected.The top of slide block 4 and the contact-making surface of lead are trapezoidal faces, and the radius of the heavy gauge wire that trapezoidal upper base length and wire clamp are folded adapts, and trapezoidal waist is about 135 degree with the angle of going to the bottom.The bottom surface of slide block 4 has the circular hole that is complementary with above-mentioned screw rod 1 diameter, and the top of screw rod 1 is stretched in the hole.The upper bar wall of screw rod 1 is provided with a cannelure 8.The both sides of slide block 4 bottom surface circular holes respectively have a screw, respectively are rotary with screens bolt 2 in the screw, and screens bolt 2 is corresponding with the cannelure 8 on screw rod 1 top, and screens bolt 2 does not come off screw rod.The front of slide block 4 has a screwed hole, is rotary with gim peg 3 in the screwed hole, through screwing in said gim peg 3, can make screw rod 1 fixing, and screw rod can't rotate.The bottom of clamp 7 is equipped with lead terminal 9, through hydraulic tongs, lead-in wire is fixed in the lead terminal.Above-mentioned have parts all to adopt metal material to process.
When the utility model uses, will go between and insert lead terminal, lead-in wire will be pressed in the lead terminal, lead-in wire is contacted firmly with wire clamp with hydraulic tongs; Screw in the screens bolt screw rod can not be come off from slide block, screw rod rotates up, and slide block is moved up, and the stressed clamping wire of top fixing cord end of the trapezoidal faces of slide block and clamp is screwed into gim peg, and screw rod is fixed, and can't rotate.Whole wire clamp installation.
