Abstract

The utility model relates to a tension-resistance wire clamp for transmission wires. The utility model is composed of a wire clamping part and a tensioning part, wherein, the wire clamping part is composed of an end plug 1, a conducting wire sleeve 2, a retracting pipe 3, a pressing spring 5 and a conical shell body 4. The end plug 1 and the conducting wire sleeve 2 are arranged in a conical head of the conical shell body 4. The retracting pipe 3 and the pressing spring 5 are arranged in a hollow cavity of the conical shell body 4. The tensioning part is composed of a tensioning sleeve 6 and a tensioning steel ring 7. The tensioning steel ring 7 is arranged on the tensioning sleeve 6. The tensioning sleeve 6 is sheathed on the outside of the conical bottom of the conical shell body 4. The retracting pipe 3 is composed of three same pressing sheets 8. The outer shape of the retracting pipe 3 is a cone which is matched with the conical shell body 4. The inner surface of the pressing sheet 8 is uniformly distributed with hill-shaped bosses. The utility model provides a tension-resistance wire clamp for transmission wires that the volume is small, the weight is light, the cost is low, the manufacture technology is simple, the construction is convenient, the connection is reliable, and the use is wide. The utility model greatly improves the construction and the repair working efficiencies of the power transmission wire, and is convenient, rapid, firm and reliable.

Description

The power line tension wire clamp

(1) technical field: the utility model relates to a kind of power line tension wire clamp, and it mainly is applicable to being connected of electric power transmission line aerial condutor and insulator.

(2) current in transmission line construction and maintenance, the strain clamp product is continued to use the strain clamp of wedge shape for many years, the version of the wedge clamp of injection mo(u)lding is housed in the shell of its employing cast aluminium body, its inner chamber is a fixed dimension, not flexible, and this series products has open defect: volume, weight are bigger, high material consumption, cost is higher, and inconvenience is installed, and applicable surface is narrower.

(3) summary of the invention: the purpose of this utility model is a kind of power line tension wire clamp of developing at the deficiencies in the prior art, it is made up of clamp part and tension section, wherein the clamp part is by plug 1, wire sleeve 2, receive pipe 3, holddown spring 5 and conical shell 4 are formed, and plug 1 and wire sleeve 2 are installed in the conehead of conical shell 4, are equipped with in the inner chamber of conical shell 4 and receive pipe 3, holddown spring 5; The tension section is made up of tension cover 6 and tension steel loop 7, and tension steel loop 7 is contained on the tension cover 6, and 6 outsides that are sleeved at the bottom of the awl of conical shell 4 are overlapped in tension; Receive pipe 3 and form by three identical clamping pieces 8, its profile be circular cone and and conical shell 4 cooperations, the inner surface of clamping piece 8 is evenly distributed with mound shape convex.This product provides that a kind of volume is little, in light weight, cost is low, technology is simple, easy construction, reliable, the broad-spectrum power line tension wire clamp of connection, and it has improved the operating efficiency of electric power transmission line construction and maintenance significantly.

(5) embodiment: the utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1,2,3,4,5,6.The power line tension wire clamp is made up of clamp part and tension section, wherein the clamp part is made up of plug 1, wire sleeve 2, receipts pipe 3, holddown spring 5 and conical shell 4, plug 1, wire sleeve 2 are installed in the conehead of conical shell 4, in the inner chamber of conical shell 4, are equipped with and receive pipe 3, holddown spring 5; The tension section is made up of tension cover 6 and tension steel loop 7, and tension steel loop 7 is contained on the tension cover 6, and 6 outsides that are sleeved at the bottom of the awl of conical shell 4 are overlapped in tension.Receive pipe 3 and form by three identical clamping pieces 8, its profile be circular cone and and conical shell 4 cooperations, the inner surface of clamping piece 8 is evenly distributed with mound shape convex.During installation, lead passes the hole of plug 1 and inserts wire sleeve 2, promotes to receive pipe 3 and moves to the awl end, receives pipe 3 and opens automatically, and lead passes receives pipe 3 and holddown spring 5, passes at the bottom of the awl of conical shell 4; Treat that lead passes length when satisfying construction requirement, spur lead in the other direction, holddown spring 5 promotes to receive pipe 3 cone head parts to conical shell 4 and moves, and the mound shape convex of receiving pipe 3 inner surfaces is locked with lead automatically, cooperate tension cover 6 and tension steel loop 7, can be on insulator with lead fixed.Receive pipe 3, conical shell 4 employing aluminium manufacturings, the mound shape convex of receipts pipe 3 inner surfaces has increased the contact area with lead effectively, guarantees that item indexs such as resistivity of the present utility model, ampacity, temperature rise satisfy the requirement of electric technical standard fully.The power line tension wire clamp that the utility model provides, technology is simple, service speed is fast, engineering time shortened to 1～2 minute by traditional 1～2 hour, improved the operating efficiency of electric power transmission line construction and maintenance significantly, and volume is little, in light weight, material consumption is few, reduces cost more than 50%.
