[0025] Please refer to Figures 1 to 3, the present utility model proposes an electrode connector 100, the electrode connector 100 includes: a plug (not shown in the figure), the plug is provided with an electrode 11, and the electrode 11 is provided with a connection hole 111; and a socket 20, the socket 20 includes a housing 21, a clamping member 22, a pressing member 23 and an elastic member 24, the housing 21 is provided with an installation cavity 211 and an insertion port 212 communicating with the installation cavity 211, the clamping member 22 is movably arranged in the installation cavity 211, and the clamping member 22 is arranged between the pressing member 23 and the elastic member 24; wherein, when the electrode 11 enters the installation cavity 211 through the insertion port 212, the connection hole 111 is clamped with the clamping member 22.

[0026] Specifically, the electrode connector 100 includes a plug and a socket 20. The plug is provided with an electrode 11, and the socket 20 is configured to include a housing 21, a clamping member 22, a pressing member 23 and an elastic member 24. The housing 21 is used for installing and protecting internal components, and the clamping member 22 is used for connecting with the electrode 11. A connection hole 111 is provided on the electrode 11, so that the clamping member 22 can partially extend into the connection hole 111 and be clamped and connected with the electrode 11. The elastic member 24 is used to keep the clamping member 22 in a tendency to extend into the connection hole 111 to fix the electrode 11. The pressing member 23 is used to drive the clamping member 22 to move, so that the clamping member 22 disengages from the connection hole 111 to unlock the electrode 11. At this time, the clamping member 22 is reset through the elastic member 24.

[0027] The way the clamping member 22 cooperates with the connection hole 111 of the electrode 11 can be that part of the clamping member 22 extends into the connection hole 111, or a clamping portion can be protruded on the clamping member 22 to better cooperate with the connection hole 111.

[0028] By providing the elastic member 24, the clamping member 22 can be reset for the next use. The elastic member 24 can be set as a spring or an elastic airbag. In one embodiment, as Figure 3 , the elastic member 24 is set as a spring, and there are two springs, which are respectively arranged on both sides of the clamping member 22, facilitating the better cooperation and fixation of the clamping member 22 with the electrode 11.

[0029] The pressing member 23 is movably arranged on the housing 21, and the specific installation method can be set according to actual needs. The pressing member 23 can be connected with the clamping member 22 or abutted against the clamping member 22. A direct hole is opened on the electrode 11 to engage with the clamping member 22, and no other fixing mechanisms are integrated on the plug or the electrode 11, making the electrode 11 simple and beautiful, with low cost and reliable connection between the electrode 11 and the socket 20.

[0030] In use, the electrode 11 is inserted into the housing 21 through the insertion interface 212. When the electrode 11 is inserted into the socket 20, the connection hole 111 of the electrode 11 will be engaged and matched with the engaging member 22. The elastic member 24 is used to keep the engaging member 22 in a tendency to extend into the connection hole 111 to fix the electrode 11. When unlocking, pressing the pressing member 23 drives the engaging member 22 to move away from the connection hole 111, and the electrode 11 can be pulled out from the socket 20. The engaging member 22 is reset by the elastic member 24 for the next use.

[0031] The technical solution of the present utility model is to open a connection hole 111 on the electrode 11. The electrode 11 passes through the insertion interface 212 of the housing 21 and extends into the installation cavity 211. When the connection hole 111 of the electrode 11 is engaged and connected with the engaging member 22, the elastic member 24 can keep the engaging member 22 in a tendency to extend into the connection hole 111 to realize the fixation of the electrode 11, so that the connection between the plug and the socket 20 is reliable. When unlocking, pressing the pressing member 23 drives the engaging member to press down, so that the engaging member 22 disengages from the connection hole 111, and the electrode 11 exits from the housing 21 and disengages from the insertion interface 212. This design does not require other fixing mechanisms to be integrated on the electrode 11 of the plug, which is simple and beautiful, has low cost, and the connection between the electrode 11 of the plug and the socket 20 is relatively stable and reliable.

[0032] In an embodiment of the present utility model, the engaging member 22 includes a bottom plate 221, a clamping protrusion 222 and an abutting portion 223 protruding from the bottom plate 221. The bottom plate 221 is movably arranged in the installation cavity 211. The elastic member 24 is arranged between the bottom plate 221 and the housing 21. The pressing member 23 is correspondingly arranged with the abutting portion 223. The clamping protrusion 222 is used for engaging and connecting with the connection hole 111.

[0033] Specifically, when the clamping protrusion 222 is engaged and connected with the connection hole 111, under the action of the elastic force of the elastic member 24, the clamping protrusion 222 can be kept in the connection hole 111 to realize self-locking and reliable connection.

[0034] Both the clamping protrusion 222 and the abutting portion 223 protrude from the bottom plate 221, and the pressing member 23 is correspondingly arranged with the abutting portion 223. Therefore, when pressing the pressing member 23 to drive the engaging member 22 to move, the bottom plate 221 drives the clamping protrusion 222 to move, so that the clamping protrusion 222 disengages from the connection hole 111, facilitating the unlocking of the electrode 11. This design is simple to operate. Only by pressing the pressing member 23 can it be unlocked without using additional tools, and the unlocking is convenient and fast. Moreover, the pressing member 23 abuts against the engaging member 22. When the engaging member 22 is reset by the elastic member 24, the pressing member 23 is also reset through the engaging member 22 for the next use.

[0035] In the embodiment of the utility model, the locking protrusion 222 is wedge-shaped, the wall surface of the locking protrusion 222 facing the plugging port 212 is an inclined surface, and the wall surface of the locking protrusion 222 away from the plugging port 212 is a vertical surface perpendicular to the bottom plate 221 .

[0036] It is worth noting that Figure 2 The protrusion 222 is wedge-shaped. When the electrode 11 is extended into the installation cavity 211, the head of the electrode 11 contacts the inclined surface of the protrusion 222. As the electrode 11 is continuously extended, the clamping member 22 is compressed to compress the elastic member 24. When the connecting hole 111 of the electrode 11 moves to the position of the protrusion 222, the clamping member 22 bounces up under the elastic force of the elastic member 24, so that the protrusion 222 is clamped and connected with the connecting hole 111 of the electrode 11.

[0037] When the electrode 11 is subjected to an axial force, due to the existence of the vertical surface, a component force opposite to the direction of movement is generated, realizing a self-locking function, ensuring the stability of the electrode 11 in a locked state, and preventing the electrode 11 from retreating and being pulled out. The wedge-shaped locking protrusion 222 can provide additional safety protection, preventing the electrode 11 from being accidentally unlocked due to vibration or other external factors, and improving the convenience of operation.

[0038] At the same time, when the electrode 11 is inserted, the inclined surface of the protrusion 222 can be used to move the clamping member 22 downward, and then the electrode 11 moves to the position of the protrusion 222, so that the protrusion 222 is connected to the corresponding position of the connecting hole 111, making the plug-in more convenient.

[0039] In an embodiment of the utility model, the pressing member 23 and the clamping member 22 are arranged in a vertical direction of the shell 21, and clamping blocks 231 are protruding at both ends of the bottom surface of the pressing member 23. The clamping block 231 is vertically provided with a clamping groove 2311, and the abutting portion 223 extends into the clamping groove 2311.

[0040] In detail, Figure 3 The pressing member 23 is arranged above the clamping member 22, and a clamping groove 2311 is arranged on the pressing member 23. The pressing member 23 clamps the abutting portion 223 of the clamping member 22 through the clamping groove 2311 to abut and cooperate with the clamping member 22, thereby driving the clamping member 22 to move, so that the unlocking is more stable and the electrode 11 can be pulled out smoothly.

[0041] In an embodiment of the utility model, an opening 213 is formed on the wall surface of the shell 21, and the pressing member 23 is partially exposed outside the opening 213. The outer wall of the pressing member 23 abuts against the inner wall around the opening 213, and the end of the pressing member 23 facing away from the opening 213 abuts against the clamping member 22.

[0042] Specifically, the pressing member 23 is disposed between the clamping member 22 and the housing 21. An opening 213 is formed in the wall surface of the housing 21, so that a part of the pressing member 23 is exposed outside the opening 213, facilitating the pressing of the pressing member 23 to drive the movement of the clamping member 22. This design reduces the assembly complexity, making the assembly process simpler and faster, and the replacement process is more convenient when replacing the pressing member.

[0043] In one embodiment, during use, the electrode 11 is inserted into the housing 21. The head of the electrode 11 contacts the wedge-shaped convex 222 of the clamping member 22. The clamping member 22 is pressed to compress the spring. When the connection hole 111 of the electrode 11 is inserted to the position of the convex 222, the clamping member 22 bounces up, and the convex 222 is clamped and connected with the electrode 11 to form an inverted buckle structure to prevent the electrode 11 from retreating and being pulled out. At the same time, the head of the electrode 11 also moves above the contact member 25 in the socket 20, and conduction is achieved between the electrode 11 and the contact member 25. When use is over, the pressing member 23 is pressed, the clamping member 22 is pressed to move downward, the convex 222 of the clamping member 22 disengages from the electrode 11, and the electrode 11 can be smoothly pulled out.

[0044] In an embodiment of the present utility model, the elastic member 24 is a spring. A guiding hole (not shown in the figure) is formed in the clamping member 22, and the elastic member 24 extends into the guiding hole and is connected with the clamping member 22.

[0045] It should be noted that a guiding hole is formed in the clamping member 22, and the elastic member 24 is located in the guiding hole. Through the guiding effect, the elastic member 24 is prevented from bending and deforming, and the service life of the elastic member 24 is prolonged. The combined use of the elastic member 24 and the guiding hole can improve the matching accuracy between the clamping member 22 and the electrode 11, ensuring the stable and reliable connection between the electrode 11 and the clamping member 22.

[0046] In addition, a guiding post 214 is further provided in the housing 21. The elastic member 24 is a spring, and the spring is sleeved on the guiding post 214, improving the stability of movement.

[0047] In an embodiment of the present utility model, a positioning post 215 is further provided in the installation cavity 211. The positioning post 215 is provided with a guiding groove 2151 along the vertical direction. The elastic member 24 and the clamping member 22 are both disposed in the guiding groove 2151, and the clamping member 22 is used to move along the guiding groove 2151.

[0048] Specifically, as Figure 2 , the spring and the clamping member 22 are nested in the guiding groove 2151. The outer wall of the clamping member 22 fits against the inner wall of the guiding groove 2151. When the clamping member 22 moves, the clamping member 22 is guided through the guiding groove 2151, and the clamping member 22 is positioned through the positioning post 215, ensuring the assembly accuracy and the stability during movement.

[0049] In an embodiment of the present utility model, the socket 20 further includes a contact member 25, which is disposed in the installation cavity 211 and is used for electrically connecting with the electrode 11.

[0050] Specifically, the contact member 25 can be a spring pin or a spring piece 252, etc.; the contact member 25 is disposed in the housing 21. After the electrode 11 is inserted, the electrode 11 is fixed by the clamping member 22. At this time, the electrode 11 is evenly pressed on the surface of the contact member 25 to contact and conduct electricity with the contact member 25, and the connection is stable and reliable.

[0051] In an embodiment of the present utility model, the contact member 25 includes a PCB board 251 and spring pieces 252. The PCB board 251 is installed in the housing 21, and a plurality of the spring pieces 252 are arranged in sequence on the PCB board 251, and the spring pieces 252 are used for electrically connecting with the electrode 11.

[0052] In detail, as Figure 3 , the contact member 25 is arranged as a PCB board 251 and spring pieces 252. The PCB board 251 is fixed in the housing 21, the spring pieces 252 are electrically connected to the PCB board 251, and the spring pieces 252 are arranged in sequence on the PCB board 251. After the electrode 11 is inserted, it is located above the PCB board 251, and the electrode 11 causes the spring pieces 252 to bend and press down to contact the gold fingers of the electrode 11, so as to realize the conduction between the electrode 11 and the PCB board 251. By cooperating with the clamping member 22 for fixation, the stable and reliable connection between the electrode 11 and the spring pieces 252 is ensured.
