Pullable male power connector

By designing a straight pull strap and a finger-blocking protrusion structure on the male power supply terminal, the problem of resistance when pulling in directions other than those specified in the design is solved, achieving resistance-free tripping and improving the ease of use and lifespan of the male power supply terminal.

AI Technical Summary

Technical Problem

When the existing power supply male terminal is pulled in a direction other than that specified in the design, pulling the tripping structure will turn the pulling force into resistance, making it difficult to pull out, especially in situations where space is limited and the performance is not good.

Method used

Design a pullable male power terminal. After the buckle tail is raised, a slightly straight pull strap is formed. The finger-blocking protrusion guides the finger to hook the middle of the pull strap and hook it in the opposite direction to the female end, so that the pull strap bends to the outside of the tail face, causing the buckle to rotate and disengage, thus avoiding the restriction on the direction of the pulling force.

Benefits of technology

This allows for unobstructed tripping regardless of the direction of the pulling force, as long as the pull is directed away from the female end, thus improving the ease of use and lifespan of the power supply male end.

Abstract

This invention belongs to the technical field of electrical connection components, specifically relating to a pullable male power supply terminal. The pullable male power supply terminal includes: a male terminal body with a latch hinged to its top surface; the rear part of the latch is bent upwards towards the top surface to form a latch tail shank, and a spring element at the hinge point between the male terminal body and the latch causes the latch tail shank to tilt upwards, with the tail end of the latch tail shank projecting vertically downwards onto the top surface. This ensures that when the pull strap, connected at both ends to the tail end of the latch tail shank and the tail surface of the male terminal body respectively, is pulled towards the tail surface due to the tilting of the latch tail shank, the gap between the top tail ridge at the junction of the top and tail surfaces and the finger stop of the pull strap is smaller than the size of a finger. The pull strap for releasing the pullable male power supply terminal does not have a specified direction of tension; as long as the tension is directed away from the female end, release can be achieved without resistance.
