[0029] Please refer to Figure 1 and Figure 2 As shown, a socket connector in a preferred embodiment of the present invention includes: an insulating body 2 and a terminal group 3.

[0030] Please refer to Figure 2-4 As shown, the terminal group 3 includes a plurality of conductive terminals embedded in the insulating body 2. The conductive terminals include a contact portion 33 exposed outside the insulating body 2 and an extension portion 34 (at least part of the contact portion 33 and the extension portion 34 are exposed outside the insulating body 2). The contact portion 33 of the conductive terminal is configured to be able to make electrical contact with the inserted plug connector, and the extension portion 34 of the conductive terminal is configured to be able to make electrical connection with the butt-jointed circuit board (which can be the circuit board of an electronic device assembled with a socket connector, and a mating component for contact conduction can be provided on the circuit board to cooperate with the extension portion) in a detachable contact conduction manner (such as crimping, elastic contact and other detachable contact conduction methods). Of course, the extension portion 34 of the conductive terminal can also be conductively connected to the circuit board of the electronic device in a fixed conductive connection manner such as welding.

[0031] In an actual use scenario, the extension portion 34 of the conductive terminal can be electrically connected to the circuit board only in a detachable contact conduction manner, or only in a fixed conductive connection manner such as welding, or also in a combined manner of both.

[0032] Preferably, the extension length and width of the extension portion 34 of the conductive terminal are configured to be greater than the welding portion of the existing terminal, so that the extension portion 34 has a relatively large conductive contact surface (similar to the structure of a gold finger), thereby achieving a good contact conduction effect. The shape of the aforementioned conductive contact surface is not particularly limited. For example, it can be a plane, a convex surface, a concave surface, etc. More preferably, a gold plating layer can be provided on the outer surface of the exposed portion of the extension portion 34 to increase the oxidation resistance and maintain good electrical conductivity.

[0033] Among them, the metal housing 1 has a receiving cavity 11 for inserting the plug connector. The insulating body 2 has a tongue plate 21 protruding forward and a plug-in plate 22 protruding backward. The tongue plate 21 is received in the receiving cavity 11 of the metal housing 1 and is configured to be able to engage with the inserted plug connector.

[0034] In an exemplary embodiment, the insulating body 2 includes a tongue plate 21, a plug-in plate 22 and a base 23. The tongue plate 21 is configured to protrude forward from the front end surface of the base 23, and the plug-in plate 22 is configured to protrude backward from the rear end surface of the base 23. The contact portion 33 of the conductive terminal is at least partially exposed on the outer surface of the tongue plate 21, and the extension portion 34 of the conductive terminal is at least partially exposed on the outer surface of the plug-in plate. The tongue plate 21, the base 23 and the plug-in plate 22 are preferably configured to be integrally formed by injection molding, wherein the tongue plate 21 and the base 23 are preferably coaxially arranged. A receiving groove 27 for receiving the extension portion 34 of the conductive terminal is recessed on the outer surface of the plug-in plate 22. When the extension portion 34 is received in the receiving groove 27, it can have an exposed contact surface for contacting and conducting with a mating component on the circuit board of the electronic device.

[0035] In an exemplary embodiment, the socket connector further includes a metal housing 1, and the metal housing 1 has a receiving cavity 11 for inserting a plug connector. The tongue plate 21 is received in the receiving cavity 11 and is configured to be able to engage with the inserted plug connector.

[0036] In an exemplary embodiment, a flange 24 surrounding the end of the tongue plate 21 protrudes from the end of the tongue plate 21 where it is combined with the base 23. The flange 24 forms a stepped structure between the tongue plate 21 and the base 23, and the metal housing 1 is sleeved on the outer peripheral surface of the flange 24. To enable the metal housing 1 to be firmly sleeved on the flange 24, the metal housing 1 and the flange 24 are preferably configured to be in interference fit.

[0037] In an exemplary embodiment, a card slot 25 is recessed on the flange 24, and a clamping portion 12 is provided on the metal housing 1 to cooperate and engage with the card slot 25. Preferably, card slots 25 are recessed on both the upper and lower surfaces of the flange 24, and two groups of clamping portions 12 are correspondingly provided on the metal housing 1. By clamping the clamping portion 12 in the card slot 25, the metal housing 1 can be firmly fixed on the flange 24.

[0038] In an exemplary embodiment, the metal housing 1 is a stamped sleeve-shaped structure, and a riveting seam 13 left by the stamping and riveting process is formed on the sleeve-shaped structure. The clamping portion 12 of the metal housing 1 is bent and extended from the rear side edge of the metal housing 1 into the receiving cavity 11. Protrusions 14 protruding into the receiving cavity 11 are also stamped on the top wall and the bottom wall of the metal housing 1, and a groove 28 matching the protrusions 14 is provided at the front end of the flange 24.

[0039] In an exemplary embodiment, a waterproof ring 26 surrounding the base 23 is convexly provided on the outer peripheral surface of the base 23. The waterproof ring 26 and the base 23 are configured to be integrally formed by injection molding, and the waterproof ring 26 is made of a plastic material with deformation ability, so that when the socket connector is assembled on the electronic device, the waterproof ring 26 can be tightly combined with the matching parts on the electronic device to achieve a good seal, so as to achieve a waterproof effect.

[0040] In an exemplary embodiment, the terminal group 3 includes a first conductive terminal 31 and a second conductive terminal 32 arranged on the same plane, and the first conductive terminal 31 and the second conductive terminal 32 are respectively configured to be stamped and integrally formed. The first conductive terminal 31 includes a left terminal 311 and a right terminal 312 spaced apart from each other, and the contact portions 33 of the left terminal 311 and the right terminal 312 are configured to protrude in opposite directions to be exposed on two opposite surfaces (upper and lower surfaces) of the tongue plate 21.

[0041] Specifically, the second conductive terminal 32 is disposed between the left terminal 311 and the right terminal 312, and includes two contact portions 33 protruding in opposite directions. The two contact portions 33 are aligned with the contact portions 33 of the left terminal 311 and the right terminal 312 respectively to be exposed on the two opposite surfaces (upper and lower surfaces) of the tongue plate 21, so that a pair of contact portions 33 for electrical contact with the inserted plug connector are formed on the two opposite surfaces of the tongue plate 21.

[0042] Specifically, the terminal assembly 3 further includes two hooks 35 , which are respectively attached to the inner side (the side away from the protruding direction of the contact portion 33 ) of the left terminal 311 and the right terminal 312 and are wrapped and fixed in the tongue plate 21 of the insulating body 2 .

[0043] The socket connector provided by the present invention constructs the extension portion 34 on the conductive terminal for electrically connecting to the circuit board of the electronic device into a structure similar to a gold finger, so that the conductive terminal can be directly electrically connected to the matching component on the circuit board of the electronic device in a contact conductive manner through the extension portion 34, thereby realizing repeated plugging and unplugging of the socket connector on the electronic device, thereby facilitating the disassembly and replacement of the socket connector.
