Abstract

A new rapid aluminum alloy strain clamp adopts the oblate cone pipe pressed out of high intensity wrought alloy as the pipe of the new rapid aluminum alloy strain clamp. The center of a radial pull plate connected with the pipe is provided with oblate holes with the same shape as the shape of the fracture of the pipe. The two sides of the radial pull plate are provided with round holes, the diameter of which is the same as the diameter of the screws positioned on the two ends of a U-shaped pull rod. The pipe is inserted through the central hole of the radial pull board and is then loaded with a wire clip, a spring and a pipe opening. A position-fixing pin fixes the pipe opening. The two ends of the U-shaped pull rod are inserted into the round holes positioned on the two sides of the radial pull board and are screwed tightly by nuts and fixed by skid-proof pins. The pipe adopts oblate cone, that is, the shape of the pipe is: the two sides are straight lines; the upper and the lower is oblate. When clamping wires, the stretch is reduced and the cable is not broken.

Description

Novel quick aluminium alloy strain clamp

Affiliated technical field

The utility model belongs to electric armour clamp distribution equipment

Background technology

At present, original electric armour clamp mounting process is loaded down with trivial details, and labor strength is big, wastes time and energy, and exists many practical problems such as moving back line and card outage cable.

Summary of the invention

In order to alleviate line construction personnel's labour intensity, improve work efficiency, the utility model provides a kind of novel quick aluminium alloy strain clamp, to solve the problem of moving back line and card outage cable in the stringing construction, reaches efficient, safety, purpose of energy saving.

The utility model technical scheme that is adopted of dealing with problems is: adopt the body of the oblate cone pipe of the repressed one-tenth of high strength Aluminium wrought alloy (being called for short aluminium alloy later on) as novel quick aluminium alloy strain clamp (being called for short strain clamp later on), the center of arm-tie is radially processed the oblate hole identical with the body section configuration, both sides process and the identical circular hole of U-shaped pull bar two ends screw diameter, the mesopore of body from arm-tie radially inserted, the wire clamp of in body, packing into successively then, the spring and the mouth of pipe, with the location pin mouth of pipe is fixed, U-shaped pull bar two ends are inserted in two mother rib lateral rotundums of arm-tie radially, tighten with nut at the pull bar two ends, fixes with anti-skidding pin; Body adopts oblate cone, and promptly the body section configuration is that both sides are straight lines, is up and down the oblate shape of semicircle, reduces stretching during clamp, does not block the outage cable.

The beneficial effects of the utility model are, the mechanical strength height, adopt oblate type body, prevent folder stretching card outage cable in the construction, conduct electricity very well, the iron-free magnetic loss, corrosion resistance is good, and is quick for installation, need not crimping tool, can alleviate line construction personnel's labour intensity significantly, improve work efficiency.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front of the present utility model external structure

Fig. 2 is an A view of the present utility model (right view)

Fig. 3 is the part sectioned view of novel quick aluminium alloy strain clamp

Among the figure 1, body, 2, wire clamp, 3, arm-tie radially, 4, the U-shaped pull bar, 5, spring, 6, the mouth of pipe, 7, nut, 8, pad, 9, anti-skidding pin, 10, the location pin, 11, lead, 12, protect line and draw cap.

Embodiment

In Fig. 3, body (1) inserts the radially mesopore of arm-tie (3), in body, pack into successively then wire clamp (2), spring (5) and the mouth of pipe (6), wire clamp is formed (the A view can be seen) by two lobes, and the mouth of pipe is fixing with location pin (10), the two ends of U-shaped pull bar (4) is inserted in the circular hole of arm-tie (3) both sides radially, pad (8) back is loaded onto at two ends, and each is tightened with two nuts (7), fix with anti-skidding pin, like this, a strain clamp is with regard to installation again; With lead (11) termination wiring tighten, have one's hair trimmed in the construction with client cables, the end is neat, slick and sly with the file finishing, put on and draw cap (12), remove wiring, front end is straight, remove dirt, " wire clamp (2) " in the strain clamp light power is pressed, made its free slippage in body, will draw cap end aligning wire clamp osculum center and slowly insert, draw from big end tailstock until lead, lead is stopped wire jumper length and is stopped to insert, and spring promotes wire clamp and discharges clamping wire automatically.Firmly lead tension back is painted at wire clamp osculum end lead and be the visible marking, be convenient to check.

Claims

A kind of novel quick aluminium alloy strain clamp, adopt the body of the oblate cone pipe of high strength Aluminium wrought alloy as novel quick aluminium alloy strain clamp, body, the U-shaped pull bar is connected with arm-tie radially, the wire clamp of packing in the body, the spring and the mouth of pipe, the location pin, anti-skidding pin is fixed, it is characterized in that: the mesopore of body from arm-tie radially inserted, the wire clamp of in body, packing into successively then, the spring and the mouth of pipe, location pin insertion tube mouth is fixed, insert in two mother rib lateral rotundums of arm-tie radially at U-shaped pull bar two ends, tighten with nut at the pull bar two ends, and anti-skidding pin inserts U-shaped pull bar two end aperture internal fixation; Body adopts oblate cone pipe, and promptly the body section configuration is that both sides are straight lines, is up and down the oblate shape of semicircle.
