[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Currently, common edge-mount connectors typically use stamped metal terminals as conductive components. The manufacturing process requires first stamping a metal sheet into conductive terminals of a specific shape, and then using injection molding to arrange and fix multiple terminals within an insulating plastic component. This process is cumbersome, involves many steps, and is costly. Therefore, a new edge-mount connector structure is needed that can simplify the manufacturing process while ensuring good electrical performance.

Each terminal module includes an insulating shell and a circuit board disposed inside the insulating shell. A metal conductive layer is disposed on the surface of the circuit board. The metal conductive layer has multiple spaced-apart grooves. The two ends of the spaced grooves extend to the edge of the circuit board, dividing the metal conductive layer into multiple mutually insulated wires. One end of each wire is connected to a terminal block, and the other end is connected to a plug-in terminal.

[0011] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0012] This utility model discloses a snap-fit ​​connector that forms conductive lines by creating partition grooves on the circuit board, replacing traditional stamped metal terminals.
