Embodiment Construction

[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0011] It can be seen from the drawings that the wire connection device is characterized in that: the wire connection device is composed of an outer sleeve I1, an outer sleeve II3, and an inner sleeve made of insulating materials 4, and the outer sleeve I1, the outer sleeve The sleeve II3 is threadedly connected with the inner sleeve 5 . The inner sleeve 5 is composed of two symmetrical rings, and a stepped through hole 4 is provided in the inner sleeve 5, and the diameter of the through holes at both ends is smaller than the diameter of the through hole in the middle. A cylindrical concave hole 2 is provided at the junction of the end faces of the outer sleeve I1 and the outer sleeve II3, and the outer diameter of the outer sleeve II3 is placed therein.

[0012] Of course, the above description is not a limitation of the present invention, and...

Abstract

The invention discloses a wire connection device. The wire connection device is characterized in that the wire connection device is formed by an external sleeve I made of insulation materials, an external sleeve II, and an internal sleeve. The external sleeve I, the external sleeve II and the internal sleeve are in threaded connection with each other. The beneficial effects are that: parts are easy to process; the wire connection device is low in cost, portable and simple to install; and circular recessed holes are arranged in the connection parts, so rain is prevented from permeating through the wire connection device so that the wire connection device is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of overhead line power supply, in particular to a wire connection device for power transmission lines. Background technique [0002] At present, in the power transmission line, the connection between the wire and the wire, between the wire and the cable, and between the cable and the cable is carried out by bolt crimping through equipment clamps or copper wire lugs. The contact area of ​​this kind of bolt crimping is small and the pressure If the connection is not reliable, it is easy to swing, and it is easy to generate heat, which will affect the safe operation of the equipment. This is the weak point of prior art. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a wire connection device with a simple and practical structure. [0004] In order to solve the above-mentioned technical problems, the technical solution of th...
