Detailed Description
The utility model will be further elucidated and described with reference to the embodiments and drawings of the specification:
the first embodiment is as follows:
referring to fig. 1-3, a self-sealing terminal structure includes an integrally formed main body.
This terminal structure includes integrated into one piece's main part, and the main part includes contact site 11, waterproof portion 12 and connecting portion 13, and waterproof portion 12 is kept away from 11 one end of contact site and is equipped with closed portion 121, makes waterproof portion 12 constitute unilateral open-ended cavity, and the cavity bottom is equipped with the glue film 122 that blocks water.
Specifically, first, the contact portion 11, the waterproof portion 12, and the connection portion 13 are integrally pressed and rolled to form a cylindrical body structure.
The contact part 11 is of a rotary spring structure and comprises a plurality of twisted bars 111, the middle parts of the bars 111 form a contact ring, and the contact ring is used for contacting the side wall of an externally inserted contact pin so as to realize external electrical connection. In this embodiment, the end of the connecting portion 13 away from the waterproof portion 12 is provided with a plurality of cards 112 for matching with a card cover structure of a card-connected electrical connector for packaging, and the optimal range of the number of the cards 112 in this embodiment is 2-6.
Connecting portion 13 is the lamellar body that the cross-section is semicircle form, and the inside cable electricity core of electric connector can be placed in connecting portion 13, in addition with the welding, can realize that the electric conductance of outside contact pin through terminal and cable is led to. This embodiment is equipped with many ribs 131 at connecting portion 13 lateral wall, increases the area of contact of connecting portion 13 and cable electricity core, promotes fixed effect to can reduce contact resistance, so that realize the heavy current circular telegram and carry.
