[0031] In the connector socket 10 and the connector plug 20 of this embodiment, by providing a weak-current contact piece 300 on the inner wall of the socket body 100 to cooperate with the weak-current contact point 203 of the connector plug 20, and by the cooperation of the strong-current terminal 200 and the first connection portion 201, simultaneous connection of strong-current and weak-current signals can be achieved. The structure is simple and the combined structure is compact.

[0032] In one embodiment, the socket body 100 is provided with a positioning convex portion 120. The positioning convex portion 120 is provided on the fixed side of the socket body 100. The fixed side is used for contacting the circuit board, and the positioning convex portion 120 is used for plugging and cooperating with the positioning hole on the circuit board.

[0033] With this setting, when using the connector socket 10 of this embodiment, a positioning hole corresponding to the positioning convex portion 120 can be opened on the circuit board. During the assembly process, the positioning convex portion 120 of the connector socket 10 is plugged corresponding to the positioning hole, and thus the installation of the connector socket 10 can be positioned. When the positioning convex portion 120 and the positioning hole are in interference fit, the connection between the connector socket 10 and the circuit board can also be fixed. In a preferred embodiment, a plurality of positioning convex portions 120 can be provided on the socket body 100 to cooperate with a plurality of positioning holes provided on the circuit board, which can improve the positioning accuracy and assembly convenience of the connector socket 10.

[0034] Furthermore, the socket body 100 further includes a support portion 140. The end face of the support portion 140 is flush with the surface of the fixed side, and the positioning convex portion 120 extends outward from the fixed side.

[0035] In this embodiment, the support portion 140 is preferably provided on the side of the socket body 100 away from the opening of the connection cavity 110. At this time, the fixed side surface of the socket body 100 can contact the circuit board and position the connector socket 10 at one end thereof. The other side of the connector socket 10 contacts the circuit board through the support portion 140. At this time, through the cooperation of the support portion 140 and the fixed side surface of the socket body 100, the connector socket 10 can be flatly attached to the circuit board, which is convenient for ensuring the flatness of the attachment between the connector socket 10 and the circuit board during the installation process.

[0036] In a preferred embodiment, one end of the strong-current terminal 200 away from the connection cavity 110 is a strong-current welding end 210, and the strong-current welding end 210 protrudes outward from the socket body 100; one end of the weak-current contact piece 300 away from the connection cavity 110 is a weak-current welding end 310, and the weak-current welding end 310 and the strong-current welding end 210 are located on the same side.

[0039] In this embodiment, by setting the high-voltage welding end 210, the low-voltage welding end 310 and the positioning convex portion 120 to be flush, during the assembly process, the installation of the connector socket 10 can be positioned by making the fixed side surface of the socket body 100 fit with the surface of the circuit board. At this time, the high-voltage welding end 210 and the low-voltage welding end 310 can be inserted into the corresponding holes on the circuit board for welding. The structure is simple and the assembly convenience is high.

[0040] In one embodiment, the outer wall of the socket body 100 is provided with a flange portion 130. The flange portion 130 protrudes from the outer wall of the socket body 100, and the flange portion 130 is spaced from the surface on the opening side of the connection cavity 110.

[0041] With this arrangement, when the connector socket 10 is connected to the external connector plug 20, the surface on the opening side of the connection cavity 110 of the socket body 100 fits flush with the connector plug 20. At this time, since the flange portion 130 is spaced from this surface, when it is necessary to separate the connector socket 10 and the connector plug 20, the operator can insert a finger or an external tool between the flange portion 130 and the surface where the opening of the connection cavity 110 is located, so as to provide a separating force for the connector socket 10 at the flange portion 130. The structure is simple and it is convenient for the disassembly and assembly of the connector socket 10 and the connector plug 20.
