Description

Technical Field

[0001] This utility model relates to a backstop structure, and more particularly to a backstop structure for a BMS signal acquisition interface connector. Background Technology

[0002] A BMS connector is an interface that connects a battery and a BMS (Battery Management System). It is mainly used to transmit information such as battery voltage, current, and temperature, as well as to control the charging and discharging of the battery. A BMS connector consists of two parts: a board-end connector and a wire-end connector. The board-end connector is connected to the circuit board, while the wire-end connector is connected to the wiring harness.

[0003] Existing wire connectors have multiple terminals inside for connecting to pins. During the use of wire connectors, some terminals may fail or be damaged for various reasons. Repairing or replacing faulty terminals is complicated and cannot be done by removing the faulty terminal for repair or replacement alone, which prolongs the repair time and increases labor costs. Utility Model Content

[0004] To overcome the drawback of not being able to individually remove the faulty terminal for repair or replacement, this utility model provides a backstop structure for a BMS signal acquisition interface connector.

[0005] The technical solution of this utility model is as follows: a backstop structure for a BMS signal acquisition interface connector, including a wire-end connector, a terminal, a limiting plate, a limiting strip, a limiting frame, a limiting block, and a protrusion. The wire-end connector has multiple insertion holes in the middle, and a terminal is slidably arranged in each insertion hole. A limiting plate is provided on the lower right side of the terminal. A limiting strip is provided on the right side inside the insertion hole. A groove is opened on the lower middle side of the wire-end connector, and a limiting frame is slidably connected in the groove. Multiple through holes for the terminal to pass through are opened on the limiting frame, and a limiting block is provided in each through hole. A recessed part adapted to the limiting block is provided on the lower middle side of the terminal. Protrusions are provided on both the front and rear sides of the limiting frame. A recessed groove is provided in the groove of the wire-end connector, and the protrusion can cooperate with the recessed groove to fix the limiting frame in the wire-end connector.

[0006] Furthermore, the left end of the limiting strip is connected to the wire connector, while the right end is suspended and does not contact the wire connector, and the limiting strip has a certain degree of elasticity.

[0007] Furthermore, the upper left end of the limiting strip is a slope.

[0008] Furthermore, it also includes a first stop, which is provided on the right side of the socket of the wire end connector.

[0009] Furthermore, a pin hole is formed between the upper side of the first stop and the insertion hole, and the entrance of the pin hole is designed at an angle.

[0010] Furthermore, it also includes a second stop, which is provided at one end of the lower side of the limit frame.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The present invention achieves double fixing of the terminal by using the combination of the limiting strip and the limiting frame. The limiting strip is used to fix a single terminal to ensure the stability of each terminal in the socket, while the limiting frame is used to fix all terminals, which improves the stability of the overall structure. In addition, when it is necessary to repair or replace the terminal, the faulty terminal can be pulled out for repair or replacement, which improves the convenience of operation and maintenance efficiency.

[0012] 2. The inclined surface design on the upper left end of the limiting strip of this utility model can guide the terminal to slide more easily over the limiting strip, reducing resistance and friction during insertion; the design of the first stop can prevent the terminal from moving excessively to the right, ensuring the correct positioning of the terminal in the socket. At the same time, the pin hole formed by the first stop and the socket facilitates pin positioning of the terminal, improving the accuracy and convenience of installation.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] A backlash prevention structure for a BMS signal acquisition interface connector, such as Figures 1-5As shown, the device includes a wire connector 1, a terminal 3, a limiting plate 31, a limiting strip 4, a limiting frame 5, a limiting block 51, and a protrusion 52. The wire connector 1 has multiple insertion holes 2 in its center, which extend through the connector 1 from both sides. The insertion holes 2 are arranged in two rows, one above the other. Each insertion hole 2 has a sliding terminal 3. The right side of the terminal 3 is used to insert pins, and the left side is used to connect a wire harness. A limiting plate 31, which is L-shaped, is located on the lower right side of the terminal 3. A limiting strip 4 is located inside the right side of the insertion hole 2, and the limiting strip 4 can cooperate with the limiting plate 31. The terminal 3 is restricted to move to the left. A groove is opened on the lower side of the middle part of the wire connector 1. A limit frame 5 is slidably connected in the groove. The limit frame 5 has multiple through holes for the terminal 3 to pass through. Each through hole is provided with a limit block 51. The lower side of the middle part of the terminal 3 is provided with a recessed part that matches the limit block 51. The limit block 51 can cooperate with the recessed part to restrict the left and right movement of the terminal 3. The limit frame 5 is provided with protrusions 52 on both the front and rear sides. The groove of the wire connector 1 is provided with a recessed groove. The protrusions 52 can cooperate with the recessed groove to fix the limit frame 5 in the wire connector 1.

[0021] In use, terminal 3 is located inside socket 2. The limiting strip 4 and the limiting frame 5 work together to fix terminal 3 inside socket 2. The limiting strip 4 is used to fix a single terminal 3, and the limiting frame 5 is used to fix all terminals 3. After a terminal 3 fails, the limiting frame 5 is pulled down so that the limiting block 51 on the limiting frame 5 no longer restricts the movement of terminal 3. Then, the limiting strip 4 in the socket 2 where the faulty terminal 3 is located is pushed down so that the limiting strip 4 no longer restricts the movement of the faulty terminal 3. At this time, the faulty terminal 3 can be pulled out to the left outside the socket 2 for repair and then put back into the socket 2, or a new terminal 3 can be put in directly. After it is put in, the limiting strip 4 resets and restricts the movement of terminal 3 again. Then, the limiting frame 5 is pushed up until the limiting block 51 on the limiting frame 5 restricts the terminal 3 again. At this time, the protrusion 52 on the limiting frame 5 is embedded in the recessed groove, which serves to fix the limiting frame 5.

[0022] The left end of the limiting strip 4 is connected to the wire connector 1, and the right end is suspended and does not contact the wire connector 1. The limiting strip 4 has a certain elasticity, which allows it to deform appropriately when subjected to force. This design allows the limiting strip 4 to have a certain elastic deformation when subjected to the terminal 3 or external force, making it smoother when the terminal 3 is inserted into the socket 2. The suspended design of the right end of the limiting strip 4 also makes it easier to be moved so as to release the restriction on the terminal 3 when needed.

[0023] The upper left end of the limiting strip 4 is a bevel. When the terminal 3 is inserted into the socket 2, it contacts the bevel of the left end of the limiting strip 4. When the terminal 3 is inserted from the left side of the socket 2, the bevel design can guide the terminal 3 to slide more easily over the limiting strip 4, reducing the resistance and friction during insertion. Until the limiting plate 31 completely passes over the limiting strip 4, the limiting strip 4 will automatically reset and abut against the limiting plate 31, thereby restricting the terminal 3 from moving to the left.

[0024] like Figure 2 and Figure 5 As shown, it also includes a first stop 21. Each wire connector 1 has a first stop 21 on the right side of the socket 2. The first stop 21 can block the limiting plate 31 when the terminal 3 is inserted into the socket 2, so that the terminal 3 does not move excessively to the right and affect the insertion of the limiting frame 5.

[0025] A pin hole is formed between the upper side of the first stop 21 and the insertion hole 2. The entrance of the pin hole is designed to be inclined. The upper side of the first stop 21 is not lower than the upper side of the limiting plate 31. The pin hole formed by the first stop 21 and the insertion hole 2 facilitates the pin positioning terminal 3. The inclined part at its entrance can compensate for a certain positioning error.

[0026] like Figure 4 and Figure 5 As shown, it also includes a second stop 53. The lower end of the limit frame 5 is provided with a second stop 53. The second stop 53 can play a limiting role when the limit frame 5 is pushed upward to reset, preventing the limit frame 5 from moving upward excessively.

[0027] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
