Description

Technical Field

[0001] This application belongs to the technical field of circuit connection, and particularly relates to a plug. Background Art

[0002] The British standard charger includes two conductive PINs and a dummy PIN. The insulating housing of the existing British standard charger is integrally injection-molded with the dummy PIN. Since injection molding has certain requirements for the wall thickness of the product, usually a uniform wall thickness or a relatively uniform wall thickness, the dummy PIN needs to be injection-molded into a hollow structure to make the wall thickness tend to be consistent with that of the insulating housing. However, this also reduces the strength of the dummy PIN, and there is a greater risk of the dummy PIN breaking in the drop test. Utility Model Content

[0011] In some embodiments, the conductive pin includes a second flange provided at one end of the conductive body close to the insulating housing.

[0012] In some embodiments, a positioning hole is further provided on the conductive sheet, and a positioning post is further provided in the insulating housing.

It can be understood that the plug can also be used for other electrical appliances, such as an adapter.

[0035] An embodiment of the present application provides a plug. Please refer to Figures 1 to 3 , the plug 100 includes an insulating housing 10, insulating pins 20 and conductive pins 30; the insulating pins 20 are of a solid structure and extend along the first direction X.

[0037] It can be understood that the insulating pins 20 are separately provided from the insulating housing 10, that is, the insulating pins 20 are formed separately and then connected to the insulating housing 10. The insulating pins 20 are used to insert into the grounding jack of the socket and open the protection door of the socket. After the protection door of the socket is opened, the conductive pins 30 can be electrically connected to the socket.

[0038] Optionally, the conductive pins 30 are injection-molded and connected to the insulating housing 10, and the insulating housing 10 is connected to the conductive pins 30 during injection molding.

Among them, there are two conductive pins 30, and the two conductive pins 30 are respectively used to connect the neutral line and the live line of the socket. The insulating pins 20 and the two conductive pins 30 are arranged in a triangular pattern.

[0040] The beneficial effects of this embodiment are as follows: The insulating pin 20 and the insulating housing 10 of this application are set as a split structure. The insulating pin 20 can be separately molded and then connected to the insulating housing 10. When the insulating pin 20 is separately molded, its wall thickness can be uniform. The insulating pin 20 can be injection-molded into a solid structure to enhance the strength of the insulating pin 20. Moreover, the insulating pin 20 can be made of a different material from the insulating housing 10. The insulating pin 20 can be made of a material with better strength and toughness to enhance the strength and toughness of the insulating pin 20, thereby solving the technical problem that the insulating pin 20 of the British standard charger has a relatively high risk of fracture in the drop test.

[0041] In some embodiments, the insulating housing 10 includes a cavity 12 extending along the first direction X, and further includes a boss 11 connected to one end of the cavity 12 along the first direction X.

[0042] Optionally, a plurality of injection molding grooves 111 are provided on the boss 11 to make the wall thickness of the boss 11 and the cavity 12 uniform, facilitating the integral injection molding of the boss 11 and the cavity 12. Optionally, jacks 121 adapted to interfaces such as type-A, type-B, or type-C are provided on the cavity 12, enabling an external interface to pass through the jacks 121 and connect to the interface inside the cavity 12.

[0043] In some embodiments, please refer to Figure 3 , the insulating pin 20 is injection-molded and connected to the insulating housing 10.

[0044] It can be understood that the injection molding connection of the insulating pin 20 and the insulating housing 10 means that after the insulating pin 20 is separately injection-molded, the insulating pin 20 is placed in the injection mold of the insulating housing 10, and when the insulating housing 10 is injection-molded, the insulating housing 10 and the insulating pin 20 are connected.

[0058] In some embodiments, please refer to Figure 5, the plug 100 further includes a conductive sheet 40 disposed within the insulating housing 10. The conductive sheet 40 is provided with a through hole 41. The conductive pin 30 includes a conductive body 31 and a pressing portion 33 disposed on the conductive body 31. The pressing portion 33 is located within the insulating housing 10. The pressing portion 33 passes through the through hole 41 to press the conductive sheet 40 against the conductive body 31 or the insulating housing 10.

[0059] There are two conductive sheets 40, and the two conductive sheets 40 respectively correspond to the two conductive pins 30.

[0060] It can be understood that the through hole 41 penetrates the conductive sheet 40 along the thickness direction of the conductive sheet 40.

[0061] It can be understood that the conductive body 31 is the main body of the conductive pin 30.

[0062] The pressing portion 33 is a conductor; please refer to Figure 6 and Figure 7 , the pressing portion 33 extends outward from the conductive body 31, passes through the through hole 41 and is bent to press the conductive sheet 40 against the conductive body 31 or the insulating housing 10. When manufacturing the plug 100, the pressing portion 33 is passed through the through hole 41 and then bent.

[0064] Optionally, an insulating sleeve 34 is provided on the conductive body 31. The insulating sleeve 34 can reduce the situation where people directly contact the conductive body 31 when holding the socket, and reduce the risk of electric shock.

[0065] The beneficial effect of this embodiment is that the conductive sheet 40 can extend to a suitable position within the insulating housing 10, facilitating connection to the circuit board within the insulating housing 10, and further facilitating connection of the conductive pin 30 to the circuit board; providing the pressing portion 33 can stably connect the conductive pin 30 to the conductive sheet 40.

[0066] In some embodiments, please refer to Figure 5 and Figure 7 , at least two pressing portions 33 are provided, and the distance between the pressing portion 33 and the center line of the through hole 41 gradually increases from the end close to the conductive body 31 to the end far from the conductive body 31.

For example, when there are two pressing portions 33, the two pressing portions 33 can be symmetrically arranged or arranged at an interval of 90° around the center line of the through hole 41. When the through hole 41 is a rectangular hole and there are three pressing portions 33, the pressing portions 33 can be respectively arranged at three side wall surfaces inside the through hole 41; alternatively, two of the pressing portions 33 and the other pressing portion 33 are respectively arranged at two opposite side wall surfaces of the through hole 41.
