A power supply device

Abstract

The invention discloses an electric power supply device, which comprises a shell, wherein the shell comprises a power supply part and an insertion part, wherein a movable cavity is arranged in the power supply part; a power supply block of which the front end and the rear end are fixedly connected with the power supply part is arranged at the center position of the movable cavity; a power supply contact pin is arranged on the end surface of the right side of the power supply block; the outer side of the power supply block is connected with a U-shaped moving part in a sliding manner; the U-shaped moving part is provided with a first screw rod in screw-thread fit connection; the first screw rod is arranged in a manner of extending towards two sides; clamping sliding cavities are symmetrically arranged on two groups of support arms at the right side of the U-shaped moving part; camping assemblies are arranged at the opposite sides of the two groups of clamping sliding cavities; and a funnel-shaped opening communicating with the movable cavity is arranged in the inner wall of the power supply part at the right side of the movable cavity. The electric power supply device is simple in structure and high in security, automatic insertion and extraction can be achieved, and the insertion and extraction combination reliability and stability are high.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to an electric power supply device. Background technique [0002] When the power supply head of the power supply device is in contact with the power supply hole, in order to ensure good electrical contact and have a stable holding force, the joint between the power supply head and the power supply hole usually has a strong joint force or friction force. This often requires a greater pull-out force when the power supply head is pulled out from the power supply hole; therefore, it brings difficulties to manually pull out the power supply head. Moreover, when pulling out manually, due to the instability of the force, it is easy to cause sparks with the electrical contacts during the process of pulling out the power supply head, endangering the safety of equipment and personal, and it is difficult to ensure the reliability and stability of the electrical connection . There is an u...
