[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] See also Figures 1 to 5 As shown, a single connector for realizing double-board connection of the utility model includes a main body 1 and a terminal member 2; and also includes a fixing member 3, one end of the terminal member 2 is fixedly mounted on the fixing member 3, the fixing member 3 is connected and mounted on the main body 1, the main body 1 is provided with a terminal hole 11, the terminal member 2 is bent and accommodated in the terminal hole 11, and the bent portion of the terminal member 2 protrudes from the two ends of the terminal hole 11 respectively to contact and connect two different PCB boards. The fixing member 3 and the main body 1 can be produced by injection molding, and both are made of insulating plastic materials; the terminal member 2 is produced by stamping and electroplating processes using conductive metal. In this embodiment, there are multiple terminal holes 11 and terminal members 2, and the multiple terminal members 2 are an integrated structure before being installed on the fixing member 3. Each terminal member 2 is bent into a shape close to "?", and one end of the terminal member 2 "?" close to "." is installed on the fixing member 3, and the other end is accommodated in the terminal hole 11 of the main body 1. Due to the bending design, the terminal member 2 protrudes from both ends of the terminal hole 11, so that it can contact and connect two PCB boards.

[0025] The single connector for realizing dual-board connection can be directly connected to two PCB boards by pressing the contact terminal 2 through the design of the main body 1 and the terminal 2, so as to meet the power supply and signal transmission needs. No welding is required, and a board-to-board connection can be realized with one connector. The structure is simple, the number of parts is small, the cost is low, the process is simple, and it is easy to use.

[0026] See also Figure 3 As shown, the fixing member 3 is provided with a mounting groove 31 for mounting the terminal member 2. The number of the mounting grooves 31 is the same as the number of the terminal members 2. The width of the mounting groove 31 is greater than the width of the terminal member 2. The groove walls on both sides of the mounting groove 31 are respectively provided with limiting grooves 32. The bottom wall of the mounting groove 31 is the lower groove wall of the limiting groove 32. The limiting groove 32 is used to limit the terminal member 2 in the depth direction of the mounting groove 31. The width of the limiting groove 32 is slightly greater than the thickness of the terminal member 2. The mounting groove 31 insulates the terminal member 2 to prevent the terminal members 2 from interfering with each other and causing a short circuit.

[0027] See also Figure 3 As shown, the fixing member 3 is also provided with an avoidance groove 33, which is recessed outward from the groove walls on both sides of the mounting groove 31, and the avoidance groove 33 is connected to the mounting groove 31. The avoidance grooves 33 on both sides of the mounting groove 31 are symmetrically arranged with the mounting groove 31 as the axis, and the distance between the bottom walls of the two symmetrically arranged avoidance grooves 33 is greater than the width of the mounting groove 31.

[0028] See also Figure 4 As shown, the terminal piece 2 is provided with a limiting protrusion 21, and the limiting protrusion 21 is formed by protruding outward from both sides of one end of the terminal piece 2. The limiting groove 32 is used to accommodate the limiting protrusion 21. The upper groove wall of the limiting groove 32 has an upward limiting effect on the limiting protrusion 21. The width of the terminal piece 2 where the limiting protrusion 21 is provided is smaller than the width of the installation groove 31 and smaller than the distance between the bottom walls of the two symmetrically arranged avoidance grooves 33.

[0029] During production, firstly, the multiple terminal pieces 2 are matched one by one, and the limiting protrusion 21 is placed into the installation groove 31 corresponding to the avoidance groove 33, and then the terminal piece 2 is pushed so that the limiting protrusion 21 enters the limiting groove 32. The limiting groove 32 prevents the terminal piece 2 from moving upward, and then the terminal piece 2 is riveted to remove the connected part, so that each terminal piece 2 becomes an independent component, and then the main body 1 and the fixing piece 3 are assembled and connected.

[0030] See also Figures 1 to 3 As shown, the fixing member 3 is further provided with a connecting column 34, which is split from the central axis into at least two petal columns, and a guide surface 35 and an abutment surface 36 are provided on the outer side of the connecting column 34, the guide surface 35 is connected to the abutment surface 36, and the abutment surface 36 is connected to the outer side surface of the connecting column 34. In this embodiment, the connecting column 34 is divided into four petal columns, and there is a clearance gap between each petal column, the guide surface 35 is a conical side surface, and the abutment surface 36 is a conical bottom surface, and the diameter at the abutment surface 36 is the largest.

[0031] See also Figure 1 to Figure 2 As shown, the main body 1 is provided with a connection hole 12, and the connection hole 12 is used to accommodate a clamping connection column 34. The inner side wall of the connection hole 12 is provided with a clamping surface 13 and an introduction surface 14. The clamping surface 13 is used to abut against the contact surface 36, and the introduction surface 14 is used to guide the connection column 34 to reduce the wear between the connection column 34 and the inner wall of the connection hole 12. The maximum inner diameter of the connection hole 12 is greater than the maximum outer diameter of the connection column 34, and the inner diameter of the junction of the clamping surface 13 and the introduction surface 14 is the smallest but greater than the minimum outer diameter of the connection column 34 and less than the maximum outer diameter of the connection column 34. The introduction surface 14 is provided at one end where the connection column 34 is inserted and the inner diameter gradually decreases.

[0032] After the terminal 2 is installed on the fixing part 3 and the waste tape is removed, glue is applied to the connecting column 34 of the fixing part 3, and the connecting column 34 is inserted into the connecting hole 12. During this process, the guide surface 35 and the introduction surface 14 rub against each other to guide, and the petals of the connecting column 34 are squeezed to elastically deform and gather together to successfully pass through the minimum inner diameter of the connecting hole 12. The petals restore the deformation and disperse. At this time, the abutting surface 36 of the connecting column 34 abuts the clamping surface 13 of the connecting hole 12, so that the connecting column 34 can be firmly inserted into the connecting hole 12, and the production and installation of the connector can be completed. The connector is tested for various performance and quality, and can be sold and used only after it is qualified.

[0033] See also Figure 5 As shown, the main body 1 is also provided with a hidden groove 15, which is connected to the terminal hole 11, and the free end of the terminal piece 2 is bent and hidden in the hidden groove 15 to prevent the tail of the terminal piece 2 from being exposed to the outside and easily being skewed or broken by collision during transportation or installation, thereby affecting the sales and use of the connector and avoiding economic losses.

[0034] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
