The electrical connector 1 can be used to connect a PCB terminal 2 and a motor terminal 3 of an automobile, and can also be used to connect two other terminals or a plurality of terminals. One end of the conductive plate 12 may be fixed and conductive by a bolt 4, and the other end of the conductive plate 12 may also be fixed by the bolt 4. For example, one end of the conductive plate 12 is fixed to the PCB terminal 2 by a bolt 4, and the other end is fixed to the motor terminal 3 by a bolt 4. The conductive plate 12 is fixed by the bolt 4, so that the vibration resistance effect of the electrical connector 1 can be improved.

The electrical connector 1 provided by the embodiment can be fixed by using the bolt 4, so that the vibration resistance effect of the electrical connector 1 is improved; the structure is simple and compact, the manufacturing cost is low, the installation is convenient, and the occupied installation space is small; the insulating end 11 can play an insulating role; the conducting strip 12 is a metal piece, the temperature change has little influence on the conducting performance, and the connecting and transmitting effects are stable; the conductive contact area of the conductive sheet 12 is large, the electrified section is also large, and large current can be conducted; the rigidity of the whole structure is high, the connection is very stable, and poor contact can be greatly avoided; the middle of the conducting strip 12 is bent, and has certain elasticity, and when the vibration frequencies at the two ends are different, the bent structure 13 can well absorb vibration and protect a path and a signal.

In other embodiments, the two ends of the conductive sheet 12 may also be fixed by riveting or welding.

Alternatively, as shown in fig. 1 and 3, the bending structure 13 is shaped like a V, S or M. This facilitates the machining of the bending structure 13 and provides the bending structure 13 with an anti-vibration effect.
