Electric power supply equipment provided with roller grooves

Abstract

The invention provides electric power supply equipment provided with roller grooves. The electric power supply equipment comprises a pin type insertion device (3) and a base hole type fixing device. The pin type insertion device (3) comprises a body part (30) and two pin type plugs (31) which are symmetrically arranged relative to a central axis of the body part (30). An upper part of each of the two pin type plugs (31) is provided with a guiding horizontal part (33) which is used for slidably cooperating with a corresponding one of two slide grooves (32) in the body part (30) and bearing a force load in an up-and-down direction. The base hole type fixing device comprises a pedestal (1) and two mounting racks (4) which are symmetrically arranged relative to the central axis and which are fixed on the pedestal (1). Each mounting rack (4) is internally provided with a slot (40) in which a corresponding one of the two pin type plugs (31) is inserted.

Description

Technical field [0001] The invention relates to the field of electric power supply, in particular to an electric power supply device provided with a roller groove. Background technique [0002] In the field of electric power supply, the combined use of a pin-type insertion device and a socket-type fixing device is a common mode. [0003] This power supply mode often clamps the pin by elastic clamping force to achieve a reliable electrical connection. However, this mode can meet general needs, but it is difficult to meet the high reliability of clamping force. In some situations that require a high degree of clamping of the power supply plug, some additional fixing force is often required to achieve a reliable connection, which often requires a very complicated mechanism to achieve. [0004] Moreover, the distance between the pins and the distance between the seat holes is often difficult to insert or the clamping force is weakened after insertion due to manufacturing errors or use ...

Problems solved by technology

However, this mode can meet the general requirements, but it is difficult to meet the situation of high clamping force reliability

In some situations where the clamping degree of the power supply plug is required to be high, some additional fixing force is often required to achieve a reliable connection, which often requires a very complicated mechanism to achieve

[0004] Moreover, for the distance between the pins and the distance between the seat holes, the distance error caused by manufacturing errors or use factors often makes it difficult to insert or the clamping force is weakened after insertion, which in turn affects the power supply stability.
