Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an embedded fixing claw. Background Art

[0002] The existing electrical connector contacts are fixed by welding a single-layer elastic claw in the shell hole, which only has the functions of fixing and detaching the contacts. When the contact is inserted into the elastic claw, the claw spring piece presses against the contact step, indicating that the contact has been fixed. When the contact needs to be repaired or replaced, the claw spring piece is stretched out from the inner hole of the elastic claw with a withdrawal tool, and the contact can be removed. However, there are two shortcomings: during the connector mating and plugging process, due to the radial pulling phenomenon of the cable terminated at the tail of the contact on the contact, the spring piece of the elastic claw swings with the deflection, causing the plug-in end of the contact to deviate from the original position. Once the deviation distance is large, there is a hole-piercing phenomenon; the current single-layer elastic claw is realized by the beryllium copper bar material machine-adding-closing-aging process, which has many processing steps and high cost; and the elastic claw is fixed in the shell hole by welding, which damages the electroplating layer on the surface of the product. For this reason, an embedded fixed claw is proposed. Utility Model Content
