CONCRETE IMPLEMENTATION

[0019] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0020] A BMS signal acquisition interface connector, such as Figures 1-5 As shown, the device includes a board-end connector 1, a wire-end connector 2, a first positioning frame 22, a fixing block 221, pins 3, terminals 4, protrusions 41, an elastic frame 42, and a limiting frame 5. The wire-end connector 2 has a first positioning frame 22 located at its upper center. The first positioning frame 22 includes four first positioning blocks arranged parallel from front to back. Two fixing blocks 221 are respectively located on the upper sides of the two middle first positioning blocks. The board-end connector 1 has four first positioning grooves 11 and two limiting grooves 111 that are adapted to the first positioning frame 22 and the fixing blocks 221. The two limiting grooves 111 are respectively located within the two middle first positioning grooves 11. The wire-end connector 2 can pass through the first positioning frame 22 and the fixing blocks 221. Block 221 is embedded into board connector 1. Board connector 1 has multiple pins 3 in the middle. The pins 3 are divided into two rows, and the pins 3 pass through the middle of board connector 1. The right side of wire connector 2 has the same number of holes 21 as the pins 3 and are positioned opposite each other. Each hole 21 has a terminal 4 that slides in it. The right end of terminal 4 has protrusions 41 on the front, back and top sides. The right end of terminal 4 has an elastic frame 42 on the lower side. The top of the protrusions 41 on the front and back sides of terminal 4 are opposite each other. The top of the protrusions 41 on the upper side of terminal 4 is opposite to the top of the elastic frame 42 on the lower side. The lower side of the middle of wire connector 2 has a sliding limit frame 5 with multiple through holes for terminal 4 to pass through.

[0021] In use, the board connector 1 and the wire connector 2 are positioned by the first positioning frame 22 and the first positioning groove 11. Then, the fixing block 221 is embedded in the limiting groove 111, thereby connecting the board connector 1 and the wire connector 2 together. At this time, the pin 3 will extend into the terminal 4 inside the socket 21. The protrusion 41 on the upper side of the terminal 4 and the elastic frame 42 on the lower side cooperate to clamp the pin 3. The protrusions 41 on the front and rear sides will restrict the forward and backward movement of the pin 3 to prevent the pin 3 from loosening or falling off the terminal 4 due to vibration. The limiting block on the limiting frame 5 will restrict the terminal 4 to the socket 21.

[0022] like Figure 2 and Figure 3As shown, the second positioning frame 23 is further included, and the upper side of the wire end connector 2 is provided with the second positioning frame 23 at the front and rear ends, the second positioning frame 23 includes two vertically arranged second positioning blocks, and the board end connector 1 is provided with a second positioning groove 12 matched with the second positioning frame 23; the second positioning frame 23 and the second positioning groove 12 can provide additional positioning support, further enhancing the connection stability and positioning accuracy between the board end connector 1 and the wire end connector 2.

[0023] The right side of the wire end connector 2 is inclined at the front and rear ends; the inclined design plays a certain guiding role, helping the user to more accurately align and insert the wire end connector 2 into the board end connector 1, making the wire end connector 2 more smooth when inserted into the board end connector 1.

[0024] The distance between the front and rear side protrusions 41 of each terminal 4 is matched with the width of the needle pin 3, and the distance between the upper side protrusion 41 and the elastic frame 42 is slightly smaller than the height of the needle pin 3; the distance between the front and rear side protrusions 41 ensures that the needle pin 3 will not fall off due to looseness, and the distance between the upper side protrusion 41 and the elastic frame 42 allows the needle pin 3 to slightly compress the elastic frame 42 when inserted into the terminal 4, thereby generating a certain clamping force, which helps to further fix the needle pin 3.

[0025] The right side of the protrusion 41 and the elastic frame 42 is inclined, and the right side of the protrusion 41 and the elastic frame 42 contacts the needle pin 3 when the needle pin 3 is inserted into the terminal 4; this design allows the needle pin 3 to more easily pass through the space between the protrusion 41 and the elastic frame 42 when inserted into the terminal 4, reducing the resistance and friction during insertion, which helps to ensure that the needle pin 3 can be smoothly and accurately inserted into place.

[0026] The left end of the elastic frame 42 is connected to the terminal 4, and the right end contacts the lower side of the inner wall of the terminal 4; when the needle pin 3 is inserted, the needle pin 3 will press the elastic frame 42, the right end of the elastic frame 42 moves to the right, and further generates a larger deformation amplitude, which not only helps the needle pin 3 to be smoothly inserted into the terminal 4, but also generates a certain clamping force through the deformation of the elastic frame 42, ensuring that the needle pin 3 is firmly fixed inside the terminal 4.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
