Detailed Description

As shown in fig. 1 to 4, the female terminal of the present invention is a terminal body 1 integrally press-formed by pressing and rolling a copper plate. The thickness of the copper plate punched coil is typically up to 9.1 mm. The front end of the terminal body 1 is provided with a cylindrical jack part 2, and the rear end of the terminal body 1 is provided with a splayed line pressing part 3. The front end of the jack portion 2 is formed with a set of circumferentially arranged front inner convex packets 4 by punching, and the front inner convex packets 4 are preferably arranged at the edge of a mouth portion 8 at the front end of the jack portion 2. The rear end of the socket part 2 is formed with a set of circumferentially arranged rear inner convex hulls 5 by stamping. And crown springs 6 are arranged in the inserting hole part 2 corresponding to the space between the front inner convex hull 4 and the rear inner convex hull 5. An opening 7 is formed in one side of the crown spring 6, and the crown spring 6 is inserted into the insertion hole 2 in front of the terminal body 1 after the opening 7 is closed by compressing the crown spring 6. The crown spring 6 is tightly attached to the inner wall of the insertion hole 2 by its own elastic force. And the two ends of the crown spring 6 are positioned by the front inner convex bag 4 and the rear inner convex bag 5, so that the crown spring can be stably arranged in the jack part and keeps effective contact.

Preferably, the crown spring 6 comprises a front mounting ring 6-1, a rear mounting ring 6-2 and a group of elastic contact strips 6-3 arranged between the front mounting ring 6-1 and the rear mounting ring 6-2 in a circumferential mode, and the middle parts of the elastic contact strips 6-3 are gathered towards the center. The front mounting ring 6-1 and the rear mounting ring 6-2 can improve the stability after mounting and can keep good contact.

Preferably, the ends of the front mounting ring 6-1 and the rear mounting ring 6-2 are provided with a set of circumferentially arranged splines 9 to increase the friction force at both ends to prevent the crown spring 6 from rotating in the socket 2, so as to further improve the stability after installation.

Preferably, the side wall of the socket part 2 is formed with a set of circumferentially arranged convex protrusions 10 by punching. Make behind terminal body 1 installs the casing of connector to play the fixed and the limiting displacement with the casing of stopping jack catch, thereby improve its stability after the installation.

Preferably, the connection points of the jack parts 2 are connected through a T-shaped connecting buckle 11. After the socket part 2 is punched and rolled into a cylinder by a copper plate, the joints of the two ends of the socket part are connected by a T-shaped connecting buckle 11, so that the strength of the socket part 2 is improved, and the socket part is prevented from being opened due to excessive plugging.

Preferably, the line pressing part 3 is provided with a group of anti-skid ribs 12 which are arranged at intervals. After the external lead is pressed on the pressing part 3, the connection strength can be further provided through the antiskid rib 12.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are included in the scope of the present invention.
