Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a BTB male and female connector. Background Technology

[0002] BTB connectors are board-to-board connectors, where the male and female connectors are mounted on two separate PCBs for mating. Patent number CN201820739537 discloses a PCB recessed board-to-board connector. This technology can reduce the longitudinal thickness of the PCB. However, in actual use, because the two contact heads of the female connector are aligned and have a V-shaped structure, when the male connector is inserted at an angle into the female connector, the male connector will abut against the contact head end of the female connector, causing pin knocking. Since both contact heads extend towards the female connector, the male connector experiences high resistance during insertion, resulting in low smoothness and poor stability. Therefore, further improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a BTB male and female connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A BTB male and female connector includes a male connector and a female connector. The male connector includes a male socket, two male terminals laterally inserted into the male socket, and a first contact piece fixed to the male socket. The female connector includes a female socket, two female terminals laterally mounted on the female socket, and a second contact piece fixed to the female socket. The female terminals include a cylindrical body, an upper spring, a lower spring, and a conductive piece. The upper and lower sides of the middle of the cylindrical body are respectively provided with hollow holes. The upper spring is located at the hollow hole on the upper side and its left end is connected to the cylindrical body. The lower spring is located at the hollow hole on the lower side and its right end is connected to the cylindrical body. The upper spring includes a V-shaped first elastic part and a first lateral extension connected to the right end of the first elastic part. The lower spring includes an inverted V-shaped second elastic part and a second lateral extension connected to the left end of the second elastic part. When the male terminal is inserted into the female terminal, the first lateral extension abuts against the upper inner wall of the male socket, and the second lateral extension abuts against the lower inner wall of the female socket.

[0006] In a further description of this utility model, the front and rear sides of the cylinder are respectively provided with lateral spring plates that arch inward.

[0007] Further description of this utility model: the male and female seats are respectively provided with slots on their front and rear sides; the first and second electrical contact pieces have the same structure and two of them are provided respectively; the first and second electrical contact pieces are L-shaped structures, including a vertical insertion part and a horizontally arranged electrical contact part; the first electrical contact piece and the second electrical contact piece are respectively inserted into the corresponding slots through the insertion part.

[0008] In a further description of this utility model, a plug-in block is provided at the middle of the right end of the male seat; the female seat is provided with a socket for inserting the plug-in block.

[0009] In a further description of this utility model, a protruding buckle is provided at the lower right end of the plug block; a buckle groove that mates with the protruding buckle is provided in the plug hole.

[0010] The beneficial effects of this utility model are as follows:

[0011] When the male connector and female connector are mated, if the male connector is inserted at an angle from bottom to top, the male terminal first contacts the left side of the first elastic part of the upper spring, causing the first elastic part to deform under pressure until it is fully inserted. If the male connector is inserted at an angle from top to bottom, the male terminal first contacts the upper part of the second lateral extension of the lower spring and inserts along the second elastic part until it is fully inserted. This avoids the male terminal directly contacting the end of the female spring during the angled insertion process, which could lead to pin failure. Furthermore, after the male terminal is inserted, the first and second lateral extensions contact the inner wall of the female connector, reducing the spring travel and increasing the contact stability. The upper and lower springs are designed in opposite directions, so the upper spring is oriented during the insertion of the male terminal, which can smoothly guide the insertion of the male terminal, reducing the resistance during insertion and improving the stability of the connection.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-7 As shown, a BTB male and female connector includes a male connector 1 and a female connector 2. The male connector 1 includes a male socket 11, two male terminals 12 that are laterally inserted into the male socket 11, and a first contact piece 13 fixed to the male socket 11. The female connector 2 includes a female socket 21, two female terminals 22 that are laterally mounted on the female socket 21, and a second contact piece 23 fixed to the female socket 21. The female terminal 22 includes a cylindrical body 221, an upper spring contact 222, a lower spring contact 223, and a conductive piece 224. The upper and lower sides of the middle part of the cylindrical body 221 are respectively provided with hollow holes 2211. The upper spring piece 222 is located at the upper hollow hole 2211 and its left end is connected to the cylinder 221; the lower spring piece 223 is located at the lower hollow hole 2211 and its right end is connected to the cylinder 221; the upper spring piece 222 includes a V-shaped first elastic part 2221 and a first lateral extension 2222 connected to the right end of the first elastic part 2221; the lower spring piece 223 includes an inverted V-shaped second elastic part 2231 and a second lateral extension 2232 connected to the left end of the second elastic part 2231; when the male terminal 12 is inserted into the female terminal 22, the first lateral extension 222... 2. The male connector 1 abuts against the upper inner wall of the male connector 11, and the second lateral extension 2232 abuts against the lower inner wall of the female connector 21. The male connector 1 and the female connector 2 are respectively mounted on two PCB boards. When the male connector 1 and the female connector 2 are inserted, it cannot be guaranteed that they will be inserted in parallel every time. If the male connector 1 is inserted obliquely from bottom to top, the male terminal 12 first abuts against the left part of the first elastic part 2221 of the upper spring 222, and the first elastic part 2221 is squeezed and deformed until it is fully inserted. If the male connector 1 is inserted obliquely from top to bottom, the male terminal 12 first abuts against the upper part of the second lateral extension 2232 of the lower spring 223. The male terminal 12 is inserted along the second elastic part 2231 until it is fully inserted, avoiding the male terminal 12 directly contacting the end of the female terminal 22 spring during the oblique insertion process, which would cause the PIN to be stuck. After the male terminal 12 is inserted, the first lateral extension 2222 and the second lateral extension 2232 respectively contact the inner wall of the female socket 21, reducing the spring travel and increasing the spring contact stability. The upper spring 222 and the lower spring 223 are designed in opposite directions. During the insertion of the male terminal 12, the upper spring 222 is in the forward direction, which can smoothly guide the insertion of the male terminal 12, reduce the resistance during insertion, and improve the insertion stability.

[0021] The front and rear sides of the cylinder 221 are respectively provided with lateral spring plates 2212 that arch inward, which abut against the male terminal 12 from the front and rear sides to improve the stability of the male terminal 12 after insertion.

[0022] The male connector 11 and the female connector 21 are respectively provided with slots 01 on their front and rear sides; the first electrical contact piece 13 and the second electrical contact piece 23 have the same structure and two of them are provided respectively; the first electrical contact piece 13 and the second electrical contact piece 23 have an L-shaped structure, including a vertical insertion part and a horizontally arranged electrical contact part; the first electrical contact piece and the second electrical contact piece 23 are respectively inserted into the corresponding slots 01 through the insertion part, and the electrical contact part contacts the electrical contact position on the PCB board.

[0023] The male seat 11 is provided with a plug block 111 at the middle of the right end; the female seat 21 is provided with a plug hole 211 for the plug block 111 to be inserted, thereby improving the accuracy and stability of the plug-in fit.

[0024] The lower right end of the plug block 111 is provided with a protruding buckle 1111; the plug hole 211 is provided with a buckle groove 2111 that cooperates with the protruding buckle 1111, which further improves the stability after insertion and prevents loosening after insertion.

[0025] The above description does not limit the technical scope of this invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this invention shall still fall within the scope of the technical solution of this invention.
