Description

Technical Field

[0001] The present invention relates to the field of plugs, and particularly to a connection structure between an electronic adapter and a pin. Background Art

[0002] Generally, electronic products are powered by an electronic adapter. The electronic adapter has rod-shaped or copper plate-shaped protruding pins, which are physically inserted into a female connector type power socket with slots or cavities. The stability of the connection structure between the pins and the electronic adapter, as well as the stability of the circuit structure, affect the safety of using the electronic adapter and the manufacturing cost. Summary of the Invention

[0003] Based on this, it is necessary to provide a connection structure between an electronic adapter and a pin, including a housing and a pin. The housing includes an upper shell and a lower shell that are mutually covered. A main board is provided inside the upper shell. Metal pins are provided on the main board. The pin is inserted into the lower shell of the housing. The upper end of the pin extends out of the lower shell, and the upper end of the pin is connected to the metal pin through a conductive part.

[0004] The conductive part of the present invention is made of a metal material, such as copper, etc. The metal pins on the main board and the pins are connected by a metal connecting piece. The metal pins are used to conduct electricity between the pins and the main board. The metal connecting piece has electrical conductivity and good elasticity. Among them, the main board of the present invention can be commonly used for electronic adapters with different-shaped plugs in various countries.

[0005] Preferably, the conductive part includes a first sleeve, a connecting piece, and a second sleeve that are connected end to end in sequence. The first sleeve is sleeved on the metal pin, and the second sleeve is sleeved on the upper end of the pin.

[0006] When installing the conductive part, the first sleeve and the second sleeve are respectively sleeved onto the metal pin and the pin, which is easy to install.

[0007] Furthermore, notches are provided on both the first sleeve and the second sleeve, and the notches longitudinally penetrate the first sleeve and the second sleeve.

[0008] The first sleeve and the second sleeve made of a metal material have good elasticity. The first sleeve and the second sleeve with notches can change the diameter under the action of an external force to facilitate their installation. When the metal pin or the pin is inserted, the diameter of the first sleeve or the second sleeve is increased. After installation, when the external force is removed, the first sleeve and the second sleeve can be firmly sleeved on the metal pin or the pin.

[0009] Furthermore, the diameter of the first sleeve is smaller than the diameter of the metal pin, and the diameter of the second sleeve is smaller than the diameter of the pin.

[0010] After the first sleeve and the second sleeve are respectively inserted into the metal needle and the plug pin, the first sleeve and the second sleeve are stretched apart by the metal needle and the plug pin, so that the first sleeve and the second sleeve generate an inward elastic force on the metal needle and the plug pin, thereby increasing friction and making the connection structure more secure.

[0011] Furthermore, the notches on the first sleeve and the second sleeve are arranged opposite to the connecting piece.

[0012] The lengths from the first sleeve wall or the second sleeve wall on both sides of the notch to the connecting piece are consistent. After the first sleeve or the second sleeve is inserted into the metal needle or the plug pin, the elastic forces generated by the first sleeve wall and the second sleeve wall on both sides of the notch on the metal needle or the plug pin are consistent, thereby avoiding uneven elastic force affecting the stability of the connection structure.

[0013] Furthermore, one end of the first sleeve and the second sleeve close to the connecting piece is folded inward to form a baffle.

[0014] The baffle is used to prevent the end of the pin or the metal needle from passing through the second sleeve or the first sleeve during installation, so that the distance between the first sleeve and the second sleeve is too long, stretching the connecting piece and affecting the service life of the connecting piece.

[0015] The principle and effect of the present invention are further described below in combination with the above technical solution:

[0016] The conductive part of the present invention is made of metal material, such as copper, etc. The metal pins and pins on the mainboard are connected by a metal connecting piece, and the metal connecting piece has conductivity and good elasticity. In addition, the conductive part of the present invention has a simple installation process, and only needs to sleeve the first sleeve and the second sleeve onto the metal pins and pins, which can reduce the labor intensity during processing, improve production efficiency, and reduce production costs.
