Jump ring type self-locking anti-loose connector

Abstract

The invention relates to a jump ring type self-locking anti-loose connector. The connector includes a plug and a socket, wherein a nut is arranged on the outer circumference of a flange of the middleportion of a head shell, one end of the nut is provided with an inner step, a locking ring is sleeved between the outer circumference of one end of the head shell and the nut, the locking ring is provided with a ring of pull-out bosses, an inner end surface of the locking ring and the head shell abut against a corrugated spring, the other end of the nut is connected with a pull ring between the nut and a tail accessory through a retaining ring for limiting, an inner wall of an outer side of the locking ring is provided with a ring of pull-off arc-shaped annular grooves, an inner wall of an inner side of the locking ring is provided with two circumferentially distributed arc-shaped through grooves, an outer circumference of one end of the head shell is provided with two or more circumferentially arranged jump ring grooves, jump rings are arranged in the jump ring grooves, and the jump rings are in one-to-one correspondence with steel balls and are not on the same axis of an outer wall of the head shell. The connector is advantaged in that the steel balls are utilized for locking connection in cooperation with circumferential rotation of limit steel balls for secondary locking, the structure is simple, locking and unlocking are convenient, self-locking loosening is prevented, and connection is stable and reliable.

Description

technical field [0001] The invention relates to a connector, in particular to a spring-type self-locking and anti-loosening electrical connector. Background technique [0002] The locking methods of traditional electrical connectors can generally be divided into the following types: 1. Bayonet type. The locking force after mating is maintained by the pressure generated by the spring. The disadvantage is that it cannot be rigidly locked. It is easy to disengage when the connector is heavy; 2. Thread type, the locking force depends on the friction between the threads, and it is easy to loosen under strong vibration and impact conditions. Some ratchets are added to prevent it, but the structure of the product Complicated, which increases the manufacturing cost; 3. In-line push-pull type-use the expansion and contraction of the steel ball to achieve the locking of the connector, but the operation is complicated. After the insertion is in place, the shell needs to be rotated to r...

Some ratchets are added to prevent it, but the structure of the product Complicated, which increases the manufacturing cost; 3. In-line push-pull type - using the expansion and contraction of the steel ball to achieve the locking of the connector, but the operation is complicated. After the insertion is in place, the shell needs to be rotated to reset the shell to lock it. If it is missed, it will appear Not locked tightly
