Description

Technical Field

[0001] The utility model relates to the technical field of conductive accessories, and more specifically to a connector for connecting a metal circuit board through a board edge. Background Art

[0002] Electrical connectors are electro-thermo-mechanical devices that allow for detachable connections to transmit power and electrical signals. Signals or electrical power are transmitted through metal conductors, and plastic housings are used in connectors to isolate the metal conductors from each other. The plastic housing is also used to align the conductors and ensure that the conductors are securely locked to the insulator. Metal circuit boards are printed circuit boards made of metal-based copper-clad boards. One side is the circuit board. The other side is a metal core substrate that facilitates heat dissipation.

[0003] Generally, the connectors used to connect the gold fingers on the edge of the circuit board have conductive terminals that clamp the corresponding gold fingers on the upper and lower sides of the circuit board. However, the same connector cannot be used on a metal circuit board with a circuit on one side and a conductor on the other side. This is because the conductor will conduct all the terminals that touch the conductor, causing a short circuit.

[0004] The traditional method is to design a piece of plastic and insert it between the metal core base of the metal circuit board and the terminal of the connector. Although this method can solve the short circuit caused by the terminal contacting the metal core base of the circuit board, it adds the procedure of assembling the piece of plastic to the assembly of the circuit board, which reduces production efficiency, increases production costs, and also increases the number of parts.

[0037] The connector body 1 includes a main body shell 11, and an upper cover 12 is provided at one end of the main body shell 11 away from the circuit board body 2. The main body shell 11 and the upper cover 12 are combined into a shell, and a conductive terminal 13 is provided between the main body shell 11 and the upper cover 12. The conductive terminal 13 is arranged in the inner cavity of the shell, and the end of the main body shell 11 away from the upper cover 12 is arranged as a plug-in board surface 14, and a plug-in slot 19 is provided at the connection between the plug-in board surface 14 and the circuit board body 2. Insertion plates 15 are fixedly provided on both sides of one end of the main body shell 11, and the insertion plates 15 are integrally formed with the main body shell 11. Fixed slots 16 are provided on both sides of the upper cover 12, and the insertion plates 15 are plugged into the fixed slots 16 to complete the relative position fixing of the main body shell 11 and the upper cover 12. A loading hole groove 18 is provided at the connection between the main body shell 11 and the conductive terminal 13, and the loading hole groove 18 is used to load and locate the relative position of the conductive terminal 13;

[0038] The conductive terminal 13 includes a terminal spring piece Ⅰ131 and a terminal spring piece Ⅱ132, and a U-shaped fork piece 133 is fixedly provided at the end of each of the terminal spring piece Ⅰ131 and the terminal spring piece Ⅱ132, and a connecting guide piece 134 is fixedly provided between the terminal spring piece Ⅰ131 and the terminal spring piece Ⅱ132. The terminal spring piece Ⅰ131, the terminal spring piece Ⅱ132, the U-shaped fork piece 133 and the connecting guide piece 134 are integrally formed and are all made of conductive metal materials; the end of the terminal spring piece Ⅰ131 away from the U-shaped fork piece 133 is set as a bent guide piece, and a limiting groove 110 is provided at the inner wall of the plug-in slot 19 at the position corresponding to the bent guide piece of the terminal spring piece Ⅰ131;

[0039] A power connection slot 17 is longitudinally formed at the connection between the upper cover 12 and the cable 3, wherein the insulation layer is stripped off at the connection between the cable 3 inserted into the power connection slot 17 and the U-shaped fork 133, and the metal wire in the cable 3 is received in the position of the U-shaped fork 133 to conduct the circuit;

[0040] The circuit board body 2 includes a circuit board substrate 21 . A conductive sheet 22 is provided at the edge of the circuit board substrate 21 and aligned with the conductive terminal 13 . The conductive sheet 22 is connected to the conductive terminal 13 to connect the circuit to the circuit board substrate 21 .

[0041] The specific implementation method is as follows: when the electrical connector is in use, the connector body 1 is designed, such as Fig.13 As shown, the upper and lower springs (i.e., the end spring piece Ⅰ131 and the end spring piece Ⅱ132) on the front of the conductive terminal 13 are designed to be flat (i.e., the end spring piece Ⅱ132), and the other spring piece has a bend (i.e., the end spring piece Ⅰ131);

[0042] During assembly, the conductive terminal 13 is loaded into the loading hole 18, so that the terminal spring piece I 131 and the terminal spring piece II 132 extend into the plug-in slot 19, wherein the bent guide piece of the terminal spring piece I 131 is placed in the position of the limiting slot 110 (see Figure 7 and 12 ); In this way, it is the conductive terminal 13 rather than the main shell 11 that contacts the conductive sheet 22 corresponding to the circuit board body 2, and the guide line is connected to the circuit board substrate 21 through the conductive terminal 13 and the conductive sheet 22 via the wire of the cable 3, and the terminal spring piece Ⅰ 131 and the terminal spring piece Ⅱ 132 corresponding to the conductive terminal 13 are in the plug-in slot 19 of the main shell 11 (see Fig.10 and Fig.11 ), when the circuit board body 2 is inserted into the plug-in slot 19, the terminal spring piece Ⅰ131 is limited by the position of the circuit board body 2 and moves up to the limiting slot 110. With the rebound force of the deformed terminal spring piece Ⅰ131, the position of the circuit board body 2 in this state is limited, ensuring the installation stability of the connector body 1 and the circuit board body 2;

[0043] The electrical connector is in a pre-assembled state when supplied to the user (see Fig. 9 ); In this pre-installed state, the conductive terminal 13 has been installed in the loading slot 18 of the main shell 11; the relative position of the conductive terminal 13 and the main shell 11 is defined; when the cable 3 is loaded on the connector body 1 through the power connection slot 17, the upper cover 12 further locks the conductive terminal 13, the upper cover 12 and the cable 3 on the main shell 11 (see Figure 5 ).
