Description

Technical Field

[0001] The utility model relates to the technical field of terminals, in particular to a combined installation structure of disposable stamping terminals. Background Art

[0002] A terminal is an electronic connection element, mainly used to connect wires and wires, and wires and electronic components in a circuit. It is usually made of metal and has good conductivity and mechanical properties. The metal area of the terminal, that is, the contact or the terminal itself, is the metal part of the connector used for contact and power transmission. In electronic equipment, circuit boards and various electrical connection occasions, terminals play a vital role to ensure the smooth transmission of current and signals.

[0003] Common terminals consist of an external insulating shell and an internal metal terminal body. There is no dedicated protective structure for the internal metal terminals except the shell. The terminal body often has only a small contact area, and most areas do not need to be exposed to the outside. Therefore, the lack of a protective structure will lead to the risk of terminal pin warping. In addition, during welding, it is difficult to weld and fix the plastic parts of the shell to the motherboard, resulting in a certain reduction in the stability of the connection.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-3The utility model provides a technical solution: it includes a terminal body 1, a rubber sleeve 2 and a shell 3. The terminal body 1 is an integrated stamping structure. The terminal body 1 is provided with an external terminal head 11, a punching groove 12, a contact spring 13 and a terminal head protrusion 14. The punching groove 12 is opened at the center of the terminal body 1 and is equidistantly distributed. The contact spring 13 is arranged in the punching groove 12. The center of the terminal body 1 is inserted into the rubber sleeve 2, and both ends pass through the rubber sleeve 2. Adapter holes 221 are opened on the rubber sleeve 2 and at positions corresponding to the contact spring 13. The rubber sleeve 2 and the shell 3 are both integrated injection molding structures. The rubber sleeve 2 is inserted into the shell 3, and a fixing component is provided on the shell 3. The outer wall of the shell 3 is fixed with a welding foot 34.

[0016] The fixing component includes a loading slot 32 and an elastic sheet 33. The loading slots 32 are opened on both sides of the shell 3 and are symmetrically distributed. The elastic sheet 33 is arranged in the loading slot 32, and the end of the elastic sheet 33 is recessed inward. The rubber sleeve 2 is composed of a positioning portion 21 and an insertion portion 22. The front side of the positioning portion 21 is against the rear side of the shell 3, and the insertion portion 22 is inserted into the shell 3. The insertion portion 22 is located in the shell 3 and an adaptation hole 221 is opened at one end.
