Have a circuit or main board. The scheduled working voltage during the operation can be

Circuit board or main board can work

none. Moreover, the circuit board or main board of an electric appliance is a power cable

Or electrical connectors. Conventionally, power cables are fixedly bonded directly to a circuit board or main board. This mounting technique is not suitable for modular production. To eliminate this problem, the male connector member and the female electrical connector member can be used to detach the power line to the circuit board or the main board.

7 and 8 show a conventional electrical connector. According to this design, the electrical connector A consists of a fork type electrically insulating housing A1 and two terminals A2. The housing A1 defines two terminal slots A11 and in each of the terminal slots A11 two front receiving holes A13 formed in the front face in communication with the stop block A12 and the terminal slot A11, respectively. ) The terminals A2 are each connected to the electrical wires B and are respectively inserted into the terminal slots A11, each having two clamping strips A21 located on the front face and a clip A22 for positioning. After insertion of the terminal A2 into the terminal slot A11 of the housing A1, the clips A22 of the terminal A2 are respectively stopped with respect to the stop block A12, and the terminal A2 with respect to the housing A1. When the electrical connector A is inserted into the matching external electrical connector C on the circuit board, the terminal C1 of the matching external electrical connector C is the front receiving hole of the housing A1. Inserted into (A13) and fastened to the clamping strip (A21) of terminal (A2) so that power is supplied to the circuit board via electrical wire (B) via electrical connector (A) and matching external electrical connector (C). .

The design of the electrical connector is not satisfactory in function. The terminal slot A13 has a larger diameter than the terminal A2 to accommodate the electrical wire B connected to the terminal A2, and the terminal A2 is deflected while being inserted into each terminal slot A11. Can be. When inserting the terminal C1 of the matching external electrical connector C into the front receiving hole A13, the clamping strip A21 of the terminal A2 is damaged by the terminal C1 of the matching external electrical connector C. Or may be permanently deformed, and the terminal C1 of the matching external electrical connector C may be blocked by the electrical connector A. FIG. Moreover, when disconnecting the electrical connector A from the matching external electrical connector C, the electrical wire B can be laid out. Unfolding of the electrical wire B can cause the interruption of the clip A22 from the stop block A12 and can result in the interruption of the terminal A2 from the housing A1.
