Large-current cable splicing structure capable of being used in narrow space

Abstract

The invention belongs to the technical field of electric power and electronic interconnection, and particularly relates to a large-current cable splicing structure capable of being used in a narrow space. The structure comprises a contact pin (1) and a mounting seat (2); the mounting seat (2) comprises a base (22) and a sleeve (21), and axial contact pins (1) are arranged on two end surfaces of the base (22); the outer wall surface of the base (22) is provided with a barrel sleeve (21), the barrel sleeve (21) is in a hollow barrel shape, and the length of the barrel sleeve (21) is larger than that of the base (22), the structure can quickly realize the installation of a large-current cable, and the installed cable is good in overall appearance smoothness, small in protrusion, small in occupied length and diameter space, better in flexibility, small in bending radius, and particularly suitable for a narrow space, and the diameter size is increased by about 20%.

Description

technical field [0001] The application belongs to the technical field of electric power and electronic interconnection, and in particular relates to a large-current cable splicing structure which can be used in a narrow space. Background technique [0002] Generally, when high-current cables carrying tens or hundreds of amperes are faced with insufficient length and need to be spliced ​​and extended, due to the need to control the contact resistance of the joint surface, special crimping and extrusion structures are often required, such as paired compression with screws and nuts Two cable heads realize reliable contact of the cable heads. These structures will take up a lot of space due to their own volume or installation requirements, thus increasing the volume and weight of the electronic equipment system. [0003] At the same time, this type of cable head requires special crimping tools such as hydraulic pliers to press together the multi-strand copper wires of the cable ...

Problems solved by technology

[0002] Generally, when high-current cables carrying tens or hundreds of amperes are faced with insufficient length and need to be spliced ​​and extended, due to the need to control the contact resistance of the joint surface, special crimping and extrusion structures are often required, such as paired compression with screws and nuts Two cable heads to achieve reliable contact of the cable heads, these structures will take up a lot of space due to their own volume or installation needs, thus increasing the volume and weight of the electronic equipment system

[0003] At the same time, this type of cable head requires special crimping tools such as hydraulic pliers to press together the multi-strand copper wires of the cable body and the high-current connection terminals. In addition to special tools, the required size of the cable head is as follows: Larger length and installation space

[0004] Third, this assembly structure requires installation and assembly personnel to have high skills and careful operation, so it will consume a long assembly time
