Abstract

The utility model relates to a novel charged wire clamp easy to be assembled/disassembled, which is a connecting part used for the electric power field that a high voltage wire T is guided down to connect with an inserting coil. The charged wire clamp comprises a slide block, a screw, a clamp body, a clamp body slideway, a lead wire apparatus, a pinhole, a circumference keyslot and a circular hole on the side block. The screw is screwed into a screw hole on the lower part of the clamp body; the slide block is placed in the clamp body slideway and is in fixed connection with the screw through a pin such that the slide block does straight line up and down movement with the rotation of the screw and thereby the purpose of clamping and loosening guide wires. . The slide block and the clamp body cooperate accurately to enter a preset position to compact the guide wires and the installation and taking is convenient and simple. The traditional line contact is changed into surface contact such that the contact surface between the guide wires and a charged wire clamp is increased. When the screw spins upward, the guide wires are compacted; and when the screw spins downward, the guide wires are loosened and the charged wire clamp is taken from the guide wires. According to load sizes, the widths of the slide block and a corresponding clamp body are increased, the contract area is increased to prepare different specifications and to meet actual requirements.

Description

A kind of novel easily assembling hot line clamp

Technical field

The utility model belongs to power domain from the link that high-voltage line T connects downlead, relates generally to a kind of novel easily assembling hot line clamp.

Background technology

At present the hot line clamp that uses as shown in Figure 1, track 5 has been done in clamp 4 inboards, by the rotation of screw rod 3 slide block 2 is moved up and down along track 5, slide block 2 is close on the clamp track 5, when moving on the slide block 2 when compressing lead is fastening, when slide block is displaced downwardly to certain position and unclamps lead, can take off.But existing hot line clamp is because slide block has rotation trend in moving process, and easily produce stuck between the slideway, thereby be difficult to tighten, sometimes tighten and can not get any more, consequent deficiency: the one, have only with link rod when stuck in actual the use and will play lead-in wire 6 to come back rotation, pull, make it to produce fatigue rupture and rupture, hot line clamp is then stayed and is occupied extreme position on the protective ring, gives to install later on and causes difficulty; The 2nd, staff's operation with high pressure is dangerous; The 3rd, press from both sides tight lead and produce arcing, the influence power supply.

Summary of the invention

The purpose of this utility model has provided and a kind ofly can prevent stuck phenomenon between hot line clamp track and the slide block, make the staff can compress or unclamp lead smoothly, increase work efficiency, guarantee a kind of novel easily assembling hot line clamp of the reliability service of staff's operation with high pressure safety and power circuit.

The technical solution of the utility model is: it is by slide block; screw rod; clamp; the clamp slideway; thread guide devices; pin-and-hole; the circumference keyway; circular hole on the slide block is formed; all adopt metal material to make; it is characterized in that: described below clamp; above; the side respectively has connecting hole; described screw rod screws in the following screwed hole of clamp; the described circular hole that matches with screw diameter of opening in the slide block lower end; the described circumferential keyway of below distance screw rod top, doing; respectively do a pin-and-hole in the circular hole both sides; fix by key pin; slide block and screw rod are linked together; described both sides at clamp are provided with the clamp slideway; the clamp slideway is trapezoidal tongue; describedly one concave volume slideway is set at clamp slideway and the corresponding position of slide block; guarantee to match with the clamp slideway all the time when slide block moves up and down; play fixedly slide block effect; avoid slide block to rotate; the mating surface of slide block and clamp upper end is the triangle beveled; describedly respectively open a semi-circular recesses that matches with the protective ring diameter on the top of slide block and the correspondence position of clamp; it can only be moved up and down; its center and lead; screw rod; all the time on same center line, thread guide devices is arranged on the side of clamp to groove on the slide block.Screw rod is put into slideway to slide block after screwing in clamp lower end threaded hole, fixedlys connected by wearing pin with screw rod, and it is moved up and down as straight line with the rotation of screw rod, realizes the purpose that clamps, unclamps lead.Slide block is cooperated with clamp enter the precalculated position exactly, compress lead, and install, win convenient and easy.And change the contact of former line into the face contact, and increased the contact-making surface of lead and hot line clamp, when revolving on the screw rod, compress lead, when the screw rod backspin, unclamp lead, take off wire clamp from lead.According to the size of load, strengthen slide block and with the width of its corresponding clamp, increase contact area, make different specifications, satisfy actual needs.

Beneficial effect:

The utility model easily assembling hot line clamp was compared with former band point wire clamp: 1, thoroughly eliminated stuck phenomenon; 2, reduced technological requirement, easily processed and reduced cost; 3, loading and unloading have easily improved operating efficiency, have reduced labour intensity, have eliminated potential safety hazard; 4, can not be trapped on the high-voltage line because of being difficult for taking off; 5, strengthen electric conductivity, guaranteed the reliability service of electrical network.
