Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the attached drawings. The following embodiments are provided to illustrate the present invention, but are not intended to limit the scope of the present invention.

As shown in fig. 1, a small self-sealing connector comprises a cover 1, a sealing plug 2, a sealing ring 3 and a shell 4. A plurality of through holes I7 are formed in the cover 1. The sealing plug 2 is a self-oil-leakage sealing ring 9. And a through hole II 8 is formed in the sealing plug 2. Through-hole II 8 is a plurality of with through-hole I7 matched with. The bottom of the housing 4 is provided with a locking mechanism 10.

As shown in fig. 2 and 3, the locking mechanism 10 is composed of a base 11 and a lock catch 12. A groove 14 is formed between the base 11 and the root 13 of the latch 12 to reduce the assembling force of the latch 12 after the terminal 5 is assembled. The housing 4 is provided with a locking buckle 15. The shackle 12 cooperates with a locking shackle 15. The root portion 13 is of an elastically bendable structure, the terminal 5 is opened before being mounted, and the latch 12 is closed after the terminal 5 is mounted. The periphery of the middle part of the shell 4 is provided with a waist groove 16 for assembling the sealing ring 3, and the periphery of the sealing ring 3 is provided with three connecting ribs 17 for forming sealing with the inner wall of the counterpart connector.

As shown in fig. 4, the rear part of the housing 4 is provided with a rectangular recess 18 for receiving the sealing plug 2. And a through hole II 8 which is slightly smaller than the diameter of the wire is arranged on the sealing plug 2 and is used for sealing the outer diameter of the wire. The periphery of the sealing plug 2 is provided with two sealing ribs 19 for sealing the inner wall of the housing 4.

As shown in FIG. 5, a post 9 is provided on the through hole I7 not equipped with a terminal. The outer diameter of the post 9 is the same as the outer diameter of the wire.

The working process is as follows: the terminal 5 is inserted from the through hole i 7 of the cap 1, passes through the through hole ii 8 of the sealing plug 2, and is mounted in the housing 4.
