[0019] This application specifically includes the following advantages:
[0020] In embodiments of this application, a gold finger connector and a gold finger socket are used. The gold finger connector includes a housing with a socket at one end, and a first gold finger PIN is provided on the inner top surface of the socket. Insertion blocks are provided on both sides of the first gold finger PIN. Limiting grooves are formed on the opposite outer walls of the insertion blocks along the length of the first gold finger PIN. A gap exists between the insertion blocks and the inner bottom surface of the socket, and the thickness of the gap is the same as the thickness of the gold finger socket. The gold finger socket includes a plate and a second gold finger PIN disposed on one side of the plate. The second gold finger PIN mates with the first gold finger PIN; slots are respectively provided on both sides of the second gold finger PIN, and limiting blocks are provided on the opposite inner walls of the slots; the limiting blocks can be slidably connected in the limiting groove; a locking groove is provided on the inner top surface of the limiting groove, and a spring piece is provided on the top surface of the limiting block that is adapted to the locking groove and can be reversibly locked; a sliding groove is provided on the inner bottom surface of the limiting groove that communicates with the connector; the sliding groove is located away from the connector relative to the locking groove, and the length of the limiting block is the same as the length of the sliding groove in the length direction of the limiting groove. By inserting the gold finger connector into the gold finger socket, two connector blocks are inserted into two slots. The limiting grooves on both sides of the connector block move along the limiting block on the inner wall of the slot. When the spring piece on the top surface of the limiting block inserts into the locking groove on the top surface of the limiting groove, the connector block is locked in a fixed position in the slot, so that the first gold finger PIN and the second gold finger PIN cooperate. Since the spring piece and the locking groove are locked in reverse, the connector block cannot move in reverse, that is, it cannot move outward, thus preventing the gold finger connector from being separated from the gold finger socket. By setting an elastic limiting post between the locking groove and the sliding groove, the forward movement of the connector block can be limited. By opening a sliding groove in the limiting groove to match the size of the limiting block, after the connector block continues to move forward, the limiting block can slide down from the sliding groove and separate from the connector block, thus allowing it to be pulled out from the gap at the bottom of the housing, thereby separating the gold finger connector from the gold finger socket. This application enables the gold finger connector to be prevented from being pulled out in reverse during the insertion and connection process, thereby improving the tightness of the connection between the two; and the housing can protect the gold fingers, making them less susceptible to damage.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] Reference Figure 1-4 This diagram illustrates a gold finger connector fastening structure according to the present invention, which specifically includes the following structure: a gold finger connector 10 and a gold finger socket 20.
[0029] The gold finger connector 10 includes a housing 11 with a connector 111 at one end. The inner top surface of the connector 111 is provided with a first gold finger PIN 12. The two sides of the first gold finger PIN 12 are respectively provided with plug blocks 13. The opposite outer walls of the plug blocks 13 are provided with limiting grooves 131 along the length direction of the first gold finger PIN 12. There is a gap between the plug blocks 13 and the inner bottom surface of the connector 111, and the thickness of the gap is the same as the thickness of the gold finger connector.
[0030] The gold finger connector 20 includes a plate 21 and a second gold finger PIN 22 disposed on one side of the plate 21. The second gold finger PIN 22 cooperates with the first gold finger PIN 12. Slots 23 are respectively opened on both sides of the second gold finger PIN 22. A limiting block 24 is provided on the opposite inner wall of the slot 23. The limiting block 24 can be slidably connected in the limiting groove 131.
[0031] The inner top surface of the limiting groove 131 is provided with a locking groove 132, and the top surface of the limiting block 24 is provided with a spring piece 241 that is adapted to the locking groove 132 and can be reversibly locked; the inner bottom surface of the limiting groove 131 is provided with a sliding groove 133 that communicates with the connector 111; the sliding groove 133 is located away from the connector 111 relative to the locking groove 132, and the length of the limiting block 24 is the same as the length of the sliding groove 133 in the length direction of the limiting groove 131.
[0032] In the embodiments of this application, a gold finger connector 10 and a gold finger socket 20 are used. The gold finger connector 10 includes a housing 11 with a connector 111 at one end. The inner top surface of the connector 111 is provided with a first gold finger PIN 12. Connecting blocks 13 are respectively provided on both sides of the first gold finger PIN 12. A limiting groove 131 is formed on the opposite outer wall of the connecting blocks 13 along the length direction of the first gold finger PIN 12. A gap exists between the connecting blocks 13 and the inner bottom surface of the connector 111, and the thickness of the gap is the same as the thickness of the gold finger connector. The gold finger socket 20 includes a plate 21 and a second gold finger PIN 22 disposed on one side of the plate 21. N pin 22 mates with the first gold finger PIN pin 12; slots 23 are respectively provided on both sides of the second gold finger PIN pin 22, and limiting blocks 24 are provided on the opposite inner walls of the slots 23; the limiting blocks 24 can be slidably connected in the limiting groove 131; a locking groove 132 is provided on the inner top surface of the limiting groove 131, and a spring piece 241 adapted to the locking groove 132 and reversibly locked is provided on the top surface of the limiting block 24; a sliding groove 133 communicating with the connector 111 is provided on the inner bottom surface of the limiting groove 131; the sliding groove 133 is on the side away from the connector 111 relative to the locking groove 132, and the length of the limiting block 24 is the same as the length of the sliding groove 133 in the length direction of the limiting groove 131. By inserting the gold finger connector 10 into the gold finger connector socket 20, two connector blocks 13 are inserted into two slots 23. The limiting grooves 131 on both sides of the connector block 13 move along the limiting blocks 24 on the inner wall of the slot 23. When the spring piece 241 on the top surface of the limiting block 24 is inserted into the locking groove 132 on the top surface of the limiting groove 131, the connector block 13 is locked in a fixed position in the slot 23, so that the first gold finger PIN 12 and the second gold finger PIN 22 cooperate. Since the spring piece 241 and the locking groove 132 are locked in reverse, the connector block 13 cannot move in reverse. The gold finger connector 10 cannot move outward, thus preventing it from separating from the gold finger socket 20. By providing an elastic limiting post 14 between the locking groove 132 and the sliding groove 133, the forward movement of the connector 13 can be limited. By creating a sliding groove 133 in the limiting groove 131 that is sized to match the limiting block 24, the limiting block 24 can slide down from the sliding groove 133 after the connector 13 continues to move forward, separating from the connector 13 and allowing it to be pulled out from the gap at the bottom of the housing 11, thus separating the gold finger connector 10 from the gold finger socket 20. This application ensures that the gold finger connector 10 and the gold finger socket 20 cannot be pulled out in reverse during the insertion process, improving the tightness of the connection. Furthermore, the housing 11 protects the gold fingers, making them less susceptible to damage.
[0033] The gold finger insertion and fastening structure in this exemplary embodiment will now be further described.
[0034] In this embodiment, the gold finger connector 10 includes a housing 11 with a connector 111 at one end, a first gold finger PIN 12 on the inner top surface of the connector 111, and a wire harness 16 connected to the first gold finger PIN 12 at the other end of the housing 11; plug blocks 13 are respectively provided on both sides of the first gold finger PIN 12; and limiting grooves 131 are formed on the opposite outer walls of the plug blocks 13 along the length direction of the first gold finger PIN 12.
[0035] The gold finger connector 20 includes a plate 21 and a second gold finger PIN 22 disposed on one side of the plate 21. The second gold finger PIN 22 cooperates with the first gold finger PIN 12. Slots 23 are respectively opened on both sides of the second gold finger PIN 22, and limiting blocks 24 are provided on the opposite inner walls of the slots 23. The limiting blocks 24 can slide within the limiting grooves 131. That is, when the gold finger connector 10 is plugged into the gold finger connector 20, the plug 13 is inserted into the slots 23, so that the first gold finger PIN 12 and the second gold finger PIN 22 can be accurately positioned. The limiting grooves 131 on both sides of the plug 13 move along the limiting blocks 24 on the inner walls of the slots 23. That is, the limiting blocks 24 slide within the limiting grooves 131. After reaching a fixed position, they can limit the two gold fingers in the longitudinal direction, so that the two can maintain a cooperative relationship and are not easy to loosen.
[0036] The inner top surface of the limiting groove 131 is provided with a locking groove 132, and the top surface of the limiting block 24 is provided with a spring piece 241 that is adapted to the locking groove 132 and can be reversibly locked. It can be understood that when the limiting groove 131 moves to the point where the locking groove 132 is opposite to the spring piece 241, the spring piece 241 is inserted into the locking groove 132 under the action of elasticity. The above-mentioned reversible locking refers to the reverse direction when the gold finger connector 10 and the gold finger socket 20 are inserted, that is, the direction in which the two are separated. By locking the spring piece 241 and the locking groove 132 in the direction of separation, the two cannot be separated after being inserted into the fixed position, making it difficult for them to loosen.
[0037] The inner bottom surface of the limiting groove 131 is provided with a sliding groove 133 that communicates with the connector 111; the sliding groove 133 is located away from the connector 111 relative to the locking groove 132, and the length of the limiting block 24 is the same as the length of the sliding groove 133 in the length direction of the limiting groove 131; there is a gap between the plug block 13 and the inner bottom surface of the connector 111, and the thickness of the gap is the same as the thickness of the gold finger connector. When the plug block 13 continues to move forward until the sliding groove 133 is opposite to the limiting block 24, the limiting block 24 can slide down from the sliding groove 133 into the bottom gap of the plug block 13. Pulling it out from this gap allows the gold finger connector 10 and the gold finger connector 20 to be separated, making them detachable and repeatedly plugged and unplugged without affecting the contact performance of the gold finger.
[0038] As an example, the length of the slot 23 is greater than the length of the first gold finger PIN 12; the limiting block 24 is disposed between the middle of the slot 23 and its inner end wall. This allows the housing 11 to completely cover the second gold finger PIN 22, achieving a stable connection, and also achieving a stable connection between the plug block 13 and the slot 23.
[0039] As an example, the top of the plug block 13 is provided with an elastic limiting post 14, which is located between the locking groove 132 and the sliding groove 133. One end of the elastic limiting post 14 elastically passes through the top of the housing 11 and is connected to a stop block 141. Specifically, a spring is provided inside the housing 11 and sleeved within the elastic limiting post 14, and the other end of the elastic limiting post 14 passes through the limiting groove 131. The elastic limiting post 14 can prevent the limiting block 24 from continuing to move towards the sliding groove 133, thereby preventing the limiting block 24 from sliding out of the sliding groove 133 and causing the gold finger connector 10 to separate from the gold finger socket 20.
[0040] As an example, the plug-in block 13 is rectangular, and the slot 23 is a rectangular groove adapted to the plug-in block 13. The top of the plug-in block 13 is fixedly connected to the inner top surface of the connector 111, and there is a certain distance between the end of the plug-in block 13 near the outer end face of the connector 111 and the connector 111. An elastic baffle 15 is provided at the bottom of the housing 11 within this distance. The height of the elastic baffle 15 is greater than the distance between the plug-in block 13 and the inner bottom surface of the housing 11. The elastic baffle 15 protrudes into the connector 111 in its natural state. In the compressed state, the elastic baffle 15 is located inside the side wall of the housing 11. Specifically, the elastic baffle 15 can be connected to the housing 11 by a spring. In the natural state of the spring, the elastic baffle 15 is pushed out of the housing 11, and when compressed, it is retracted into the housing 11. The elastic baffle 15 further restricts the limiting block 24, preventing it from sliding out of the groove 133 when it protrudes. Simultaneously, the protruding elastic baffle 15 blocks the lower gap of the housing 11, preventing external impurities from entering the housing 11. When it is necessary to separate the gold finger connector 10 and the gold finger socket 20, the housing 11 is lifted upwards, and the limiting block 24 applies pressure to the elastic baffle 15, causing it to retract into the side wall of the housing 11 before being pulled out.
[0041] As an example, the top surface of the limiting block 24 has a shallow groove 242, which can be understood as a shallow groove. The spring piece 241 is in the shape of an inclined triangle. Due to the longer inclined side and shorter inclined side of the inclined triangle, it can achieve a forward movement and reverse locking state. The spring piece 241 is connected to the shallow groove 242. In its natural state, the spring piece 241 protrudes from the top surface of the limiting block 24. When the spring piece 241 is pressed, it is compressed into the shallow groove 242. When the plug block 13 is inserted into the slot 23, the limiting groove 131 and the limiting block 24 move relative to each other until the spring piece 241 is engaged in the locking groove 132. Then, the plug block 13 cannot move towards the end away from the slot 23, thereby locking it in reverse and improving the connection tightness of the gold finger connector 10 and the gold finger socket 20.
[0042] As an example, the slot 23 is formed on a PCB board, and the second gold finger pin 22 is connected to the PCB board.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
