High-current wire spring contact piece module structure and high-current terminal connection structure

Abstract

The invention discloses a high-current wire spring contact piece module structure and a high-current terminal connection structure. The high-current wire spring contact piece module structure comprises a sheath, a first wire spring set and a second wire spring set, wherein the first wire spring set and the second wire spring set are clamped in the sheath and are arranged up and down at intervals,wherein each of the first wire spring set and the second wire spring set comprises at least one wire spring contact piece; at least two protruding first contact points are arranged on the surface, which faces the second wire spring set, of the first wire spring set at intervals; at least two second contact points in one-to-one correspondence with the first contact points up and down are arranged on the surface, which faces the first wire spring set, of the second wire spring set in a protruding mode; gaps are formed between the first contact points and the second contact points; and two ends of the sheath are provided with insertion openings in the positions corresponding to the gaps. Through the modular structural design, the overcurrent between the terminals can be flexibly changed, andthe diversified requirements of actual current are met. The high-current wire spring contact piece module structure further has the advantages of being simple in structure, convenient to assemble, safe, reliable and wide in application range.

Description

Technical field [0001] The invention relates to the technical field of connectors, in particular to a high-current wire spring contact piece module structure and a high-current terminal connection structure. Background technique [0002] In the high-current terminal application market of high-voltage connectors, the first type is an integrated round terminal, which uses a revolving spring and torsion spring structure as the terminal contact piece, and the second type is an integrated sheet metal terminal that uses a mesh contact. These two kinds of terminals are basically customized current terminals, and the cost of mold opening is high, and it is difficult to match the connector with the overcurrent and the structure in response to the different current requirements in the market. The first type of terminal shell Generally, it is formed by machining, and the efficiency is low. The inner contact piece of the terminal is generally stamped and formed by a copper alloy mold, and th...

[0002] In the application market of high-voltage connectors and high-current terminals, the first type is an integrated circular terminal, which uses a torsion spring and a torsion spring structure as a terminal contact piece, and the second type is an integrated sheet metal terminal, which uses a mesh contact These two types of terminals are basically customized current terminals, the cost of mold opening is high, and when responding to different current demands in the market, it is difficult to match connectors with consistent overcurrent and structure. The first type of terminal shell Generally, it is formed by machining, and the efficiency is low. The inner contact piece of the terminal is usually stamped and formed by a copper alloy mold, and the mold opening cost is high. The shell of the second type of terminal is formed by sheet metal, and the inner contact piece of the terminal is formed by stamping. The shell and the inner contact piece are generally developed in a one-to-one correspondence. The development cycle is long, and it is not suitable for the needs of different space structures. When there is a higher or lower overcurrent requirement, a new terminal needs to be redeveloped
