Elastic terminal

Abstract

The invention discloses an elastic terminal. The elastic terminal comprises a welding base portion, a contact elastic piece and a supporting elastic piece; the contact elastic piece comprises a first elastic arm and a first contact arm; the first elastic arm is integrally bent to extend from the welding base portion and suspended above the welding base portion; a deformation escape space is formed between the first elastic arm and the welding base portion; the supporting elastic piece comprises a second elastic arm and a second contact portion formed at the free end of the second elastic arm; the second elastic arm is integrally bent to extend from the welding base portion; the second elastic arm is suspended in the deformation escape space, and the second contact portion props against the first elastic arm in a supporting manner; as a result, the first contact portion of the contact elastic piece is enabled to have relatively large positive force; the design of the two elastic arms is capable of effectively avoiding instantaneous breakage of the product due to resonance under external force impact, and the contact stability of the elastic terminal with components is better and the performance of the product is improved; meanwhile, the elastic terminal has the advantages of low manufacturing cost, steady structure, easy suction, small space usage and the like.

Description

technical field [0001] The present invention relates to the technical field of connecting terminals, in particular to an elastic terminal. Background technique [0002] In today's era of portable electronic devices becoming more and more diverse, light and thin, high intelligence, drop resistance, waterproof, dustproof, etc. have gradually become the necessary development trend of portable equipment, especially electronic products such as mobile phones, tablet computers, etc. The anti-drop and anti-shock performance is particularly important. In order to ensure that the high-speed portable equipment can still operate normally when it is impacted by external forces, the connection interface with high stable contact performance plays a critical role. [0003] At present, such as mobile phone battery holder connectors usually use an elastic terminal connector embedded in the insulating seat to achieve connection, and this kind of connector often takes up a lot of space because...

Problems solved by technology

[0003] At present, such as mobile phone battery holder connectors usually use an elastic terminal connector embedded in the insulating seat to achieve connection, and this kind of connector often takes up a lot of space because of the insulating seat, and its single elastic terminal is difficult to provide a large Positive contact force, and long-term contact is prone to permanent deformation, which will increase the contact resistance or make normal contact impossible. When the natural frequency of the single elastic arm is very likely to appear close to or equal to the impact vibration frequency when it is impacted by an external force, resonance will occur. There are many problems such as contact transients, so it cannot meet the more reliable connection requirements of emerging portable devices
