Embodiment

[0016] Example: such as figure 1 As shown, a high-elastic spring claw jack is composed of a sheath 1, a spring claw 2 and a socket 3. The spring claw 2 is the core part of the spring claw jack. It is made of beryllium bronze strip after blanking, bending, and rolling to form a rotary part with multiple elastic contact pieces (refer to figure 2 , image 3 ), the ends of multiple elastic contact pieces are closed to form an inscribed circle. When the pin is inserted into the spring claw socket, the pin will properly stretch the elastic contact piece at the inscribed circle to form an elastic connection. electrical connection. In order to guide, the end of each elastic contact piece is bent with a certain circular arc. The spring claw 2 is assembled on the outer circle of the socket 3, and the axial limit is realized by the step set by the socket 3. In order to reliably fix the spring claw 2 on the socket 3, a sheath 1 is configured, and the sheath 1 passes through Interfere...

Abstract

The invention discloses a jack of a high-elasticity pawl spring type, comprising a jacket (1), a pawl spring (2) and a jack. The pawl spring (2) is assembled and arranged on the excircle of the jack (3) which is provided with steps for realizing the axial limitation of the pawl spring (2), the pawl spring (2) is a rotary spare part provided with a plurality of elastic contact sheets, the end parts of the plurality of elastic contact sheets are folded into an incircle to form an elastic structure which can be strutted and have closing force, the jacket (1) is sleeved on the peripheries of the pawl spring (2) and the jack (3) so as to fix the pawl spring (2) in the jack (3), a guiding part in arc bending is arranged at the end part of each elastic contact sheet, and the jacket (1) and the jack (3) are in interference fit and compression joint to reliably fix the pawl spring (2) in the jack (3). The invention has a simple structure, high contact reliability, long contact length, small plugging force, overstress deformation resistance and favorable guidance.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a highly elastic spring-claw jack. Background technique [0002] There are many types of connector contacts, and the commonly used ones are cylindrical contacts, stranded elastic pin contacts, wire spring socket contacts, crown spring socket contacts and square contacts. Among these contacts, wire spring socket contacts and stranded wire elastic pin contacts have high reliability and low insertion and withdrawal force. The structural type and mechanical model of the crown spring socket contact are the same as the wire spring socket contact, and while maintaining the advantages, it avoids the complex structure, broken wire, low probe damage resistance, The current carrying capacity is small and it does not support live plugging (plug and play). However, both the crown spring jack and the wire spring jack are in contact with the pins in the middle area of ​​the jacks...
