Description

Lead wire protection assembly

Technical Field

The invention belongs to the field of electrical parts, and particularly relates to a lead protection assembly.

Background

When the wire is connected with the wiring terminal, the wire ends of the multiple wire cores are further twisted, and then the wire ends are connected with the wiring terminal. The phase position of the wiring terminal and the phase sequence of the wire are required to be clearly separated, the small-section aluminum core wire and the aluminum wiring terminal are required to be connected, an oxide layer is required to be removed before connection, a copper-aluminum transition joint is adopted when the large-section aluminum core wire and the copper wiring terminal are connected, and a proper distance is required to be kept between a wire insulating layer and the wiring terminal. When the flexible lead is connected with the wiring terminal, the phenomena of loosening, strand breaking, exposure and the like of the multi-strand fine wire core are not allowed to occur. The connection between the wire head and the wiring terminal is smooth, firm and reliable, and the contact resistance is reduced as much as possible. The end of the wire, whether single-strand or multi-strand, must be inserted into the hole and the insulation layer must not be inserted into the hole.

The wiring terminals are connected through the wires, the insulating rubber sleeves are usually only installed on the outer sides of the leads for protecting the wires, the insulating rubber sleeves are easy to damage, the problem that the wires leak outwards exists, the connection positions of the leads and the wiring terminals are directly exposed or simply protected, the connection positions of the leads and the wiring terminals are prone to poor contact or falling off, and therefore the leads with the wiring terminals cannot play any role when being connected with two electric devices.
