Multi-core lead electric connection method and fixing device

Abstract

The invention discloses a multi-core lead electric connection method and an electric connection fixing device. The multi-core lead electric connection method comprises the following steps: (1) stripping insulating wrapper at the connection end of leads, so that conductive core wires are exposed; (2) inserting the exposed conductive core wires of two leads parallelly, staggeredly and mutually to form mutual electric shock connection at the peripheries of the conductive core wires, wherein the section of the electric connection position has a honeycomb shape; and (3) fixing the conductive core wires which are inserted mutually to form electric connection. The fixing device comprises a bushing, wherein the exposed conducive core wires are placed in the bushing and inserted parallelly, staggeredly and mutually; threaded holes communicated with the cavity of the bushing are formed in the wall of the bushing; and bolts pass through the threaded hole and lock and fix the conductive core wires in the cavity of the bushing. According to the parallel and staggered insertion electric connection manner, the contact area of the electric connection position of the core wires is enlarged, the problems that resistance heat is easy to generate and oxidation is easy to occur because the joint is loosened or the contact area is small in the prior art are solved well, stability of conductivity is guaranteed, service life of the circuit is prolonged, and maintenance ratio of the circuit is reduced.

Description

technical field [0001] The invention relates to an electrical connection method of a multi-core wire, and simultaneously provides an electrical connection fixing device. Background technique [0002] There are two existing multi-core wire electrical connection methods, one is the conductive core wire winding type, which is wrapped with insulating tape after two conductive core wires are wound. The disadvantages of this connection method are: one is thermal expansion and cooling. Under the influence of shrinkage, the wires will be loose, and resistance heat will be generated at the joints and oxidized, resulting in the aging of the lines; the second is that the direction of electron movement at the joints is inconsistent, and the instantaneous current is weakened; The wire pliers clamp and fix both ends of the casing. This connection method will create gaps at the butt joints, which are mainly conducted through the pipe wall through the clamping point between the casing and t...

Problems solved by technology

[0002] There are two existing electrical connection methods for multi-core wires. One is the conductive core wire winding type, which is wrapped with insulating tape after two conductive core wires are wound. Under the influence of shrinkage, the wire will loosen, and the joint will generate resistance heat and oxidize, resulting in aging of the line; the second is that the direction of electron movement at the joint is inconsistent, and the instantaneous current is weakened; the other is that the conductive core wire is inserted into the conductive sleeve for butt joint, and then press Clamp and fix the two ends of the casing with wire pliers. There will be a gap at the butt joint of this connection method, which is mainly conducted through the tube wall through the clamping point of the casing and the conductive core wire. Due to the small contact area, it is easy to generate resistance heat and oxidize , lead to aging of the line, decline in electrical conductivity, and high maintenance rate; moreover, this butt clamping and fixing method requires the use of crimping pliers, which must be completed by two people because the crimping pliers are large and heavy
