Waterproof wire outlet device of electric vehicle controller

Abstract

A waterproof outlet device for an electric vehicle controller of the present invention comprises an upper basic body, a lower basic body, an upper intermediate body and a lower intermediate body, the four of which are strips of equal length; the upper edge of the upper basic body and the lower The edges and the left and right edges of the four are provided with walls protruding from the platform; the lower edges of the upper basic body and the lower intermediate body are 5 pairs of inwardly recessed semi-circular arcs and the protrusions are evenly spaced; the lower basic body and the upper intermediate body The upper edge of the upper middle body is 5 pairs of inwardly concave semicircular arcs and the notches matching the protrusions of the upper basic body are evenly distributed; the lower edge of the upper middle body is 5 protrusions and their corresponding notches are evenly distributed; the lower middle body The upper edge of the upper edge is 5 notches and their corresponding protrusions are evenly distributed; the four are inlaid and connected by protrusions and notches in turn; therefore, this device can separate the wires in the control box from the round hole formed by the semicircle arc, Filling glue into the platform can seal the gap between the wires very well, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of electric vehicle control equipment, in particular to a waterproof outlet device for an electric vehicle controller. Background technique [0002] As the core part of electric vehicles, electric vehicle controllers have high requirements for waterproof performance. If water enters the controller accidentally, the internal circuit will be damp, causing damage to components or short circuits, making the entire controller unable to work. At present, many The number of electric vehicle controller repairs due to water ingress doubles after the heavy rain in all regions; therefore, waterproof performance is a key parameter for user experience in the electric vehicle industry. One of the important reasons why the waterproofing of electric vehicles is not easy to achieve is that many wiring harnesses need to come out of the circuit board of the controller, and the gap between the wires cannot be completely sealed when the g...
