Description

Double-unit clamping tool

Technical Field

The utility model relates to a link fitting that continues on the transmission line directly relates to two unit holders, and the specially adapted uses on the low pressure transmission and distribution lines after the upgrading.

Background

The power transmission to the user is accomplished through low voltage transmission line, and the user's branch line is pressed firmly and the trunk line through parallel groove clamp in low voltage transmission line engineering construction, and parallel groove clamp's effect is: the end of the subscriber branch line is firmly pressed with the trunk line, and then the permanent dead connection can be regarded. The parallel groove clamp has the advantages that: the end of the user branch line is closely and reliably electrically connected with the main line, and the contact is good. The disadvantages after the parallel groove clamp is operated are: the one-way and parallel groove clamps are limited to the crimping of the single branch conductor. And secondly, because the original parallel groove clamp is only limited to be pressed into a single line, when a plurality of wires are pressed into the parallel groove clamp simultaneously, no redundant wire connecting positions exist on the original parallel groove clamp. And thirdly, the dynamic and static clamping bodies of the original parallel groove clamp, the trunk line and the end of the branch lead are simultaneously crimped by the press bolts, and the whole parallel groove clamp is separated from the trunk line when the press bolts are loosened.

The common technical problem which is not solved by people after the parallel groove clamp is operated is that: when the branch wire is connected with the parallel groove clamp on the T joint of the main line, the branch wire is connected with the main line, and the branch wire is connected with the parallel groove clamp on the T joint of the main line.

When the equipment and appliances (such as a finger control switch, a safety protection device, a support hardware tool, a line accessory and the like) at the rear end of the branch conductor on the crimping and parallel groove clamp are subjected to irregular inspection and regular inspection after times, natural damage occurs, sudden failure occurs and maintenance is required or a damaged device needs to be replaced, the possibility of maintenance or replacement is not particularly possible under the condition that the main line is not opened and the power is not interrupted.
