Terminal elastic sheet and making method thereof

Abstract

The invention discloses a terminal elastic sheet and a making method thereof. The terminal elastic sheet comprises a substrate, an elastic arm bent and formed at the end part of the substrate and an elastic contact sheet bent and formed at the tail end of the elastic arm and in an inverted U shape; the elastic contact sheet is inwardly bent to form a bent sheet; a first protection wall plate and a second protection wall plate are formed at two sides of the substrate; the elastic arm is placed between the first protection wall plate and the second protection wall plate; a first block piece and a second block piece are formed at the end parts of the first protection wall plate and the second protection wall plate respectively; the first block piece and the second block piece are placed on upper surfaces of two sides of the elastic arm for blocking the elastic arm; when the elastic arm is pressed downwardly by an external force or bounces up under the self restoring force, the elastic arm is moved between the first protection wall plate and the second protection wall plate, and thus, a phenomenon that the elastic arm is damaged due to pressing bias of the elastic arm does not happen. As the first block piece and the second block piece at the end parts of the first protection wall plate and the second protection wall plate are placed on the upper surfaces of two sides of the elastic arm respectively for blocking the elastic arm, the elastic arm is in a compressed state, and the elastic arm at the time has a strong elastic force.

Description

[0001] Technical field: [0002] The invention relates to the technical field of hardware terminal products, in particular to a terminal shrapnel and a manufacturing method thereof. [0003] Background technique: [0004] The main supporting fields of electrical connectors are transportation, communication, network, IT, medical treatment, home appliances, etc. The rapid development of product technology in supporting fields and the rapid growth of the market have strongly driven the development of connector technology. So far, the connector has developed into a series and professional product with complete product categories, rich varieties and specifications, diverse structure types, subdivision of professional directions, obvious industry characteristics, and standard system specifications. [0005] The terminal elastic piece is a part of the electrical connector. The terminal elastic piece in the prior art generally includes a substrate and an elastic contact arm formed on the subst...

AI Technical Summary

Problems solved by technology

However, the elastic contact arm of the terminal shrapnel in the prior art does not have any protection mechanism, so that the elastic contact arm may be insufficiently elastic or damaged due to a large external force.
