Description

Electric power supply device with roller and contact sensor

Technical field

The invention relates to the field of electric power supply, in particular to an electric power supply device with a roller and a contact sensor.

Background technique

In the field of electric power supply, the use of a pin-type insertion device in combination with a seat-hole fixing device is a common mode.

This type of power supply often clamps the pin by elastic clamping force for a reliable electrical connection. However, this mode can be satisfied for general needs, and it is difficult to satisfy the case where the clamping force reliability is high. In some cases where the degree of clamping of the power plug is high, some additional fixing force is often required to achieve a reliable connection, which often requires a very complicated mechanism.

Moreover, the distance error between the distance between the studs and the distance between the stud holes due to manufacturing errors or usage factors and the like often causes the clamping force to be weakened after being difficult to insert or insert, thereby affecting the power supply stability.
