Wiring harness switch device

Abstract

The invention discloses a wiring harness switch device which comprises an elastic ejector rod and an elastic contact assembly, wherein the elastic ejector rod is used for matching with plugging of a spring bolt to produce displacement; the elastic contact assembly is matched with the elastic ejector rod and connected with a control circuit; the wiring harness switch device further comprises an ejector block matched with the end of the elastic ejector rod; an insertion groove used for inserting the spring bolt is formed in one end of the ejector block; a compression spring is connected to the other opposite end and is used for accumulating compressing force when the ejector block is pressed by the spring bolt and feeding the ejector block into the bottom of the elastic ejector rod when thespring bolt is pulled out. The arrangement of the ejector block in the wiring harness switch device is just opposite to that in the prior art; the ejector block is arranged in the insertion groove used for inserting the spring bolt, the other end of the ejector block is connected with the compression spring, while the position at which the elastic ejector rod is positioned is positioned on one side on which the spring bolt is inserted. According to the design, a process of pushing the ejector block off the lower side of the elastic ejector rod is modified to be realized by an insertion actionof the spring bolt. During unlocking, the condition that the ejector block and the elastic ejector rod are mutually clamped due to extrusion of the elastic ejector rod is avoided, and the unlocking failure is also avoided.

Description

technical field [0001] The invention relates to the technical field of safety protection appliances, and more specifically, to a wire harness switch device. Background technique [0002] The wire harness switch device involved in the present invention is generally used in conjunction with a lock device. Taking the lock device for a vehicle seat belt as an example, when the vehicle is started and running, if the occupant does not wear a seat belt, the wire harness that cooperates with the lock device The switch component is in the power-on state, and the warning sign on the instrument panel is always on when the seat belt is not fastened. At the same time, the central control device will control the sound of the prompt; The warning sign of the belt is off, and the vehicle is running normally. [0003] At present, the wire harness switch used in the prior art is generally provided with an elastic mechanism and a push mechanism. When the lock tongue is inserted into the lock d...
