Water-proof switch device for vehicle

Abstract

The disclosed waterproof switching device is in use for switching and turning on / off direction light of vehicle. The waterproof switching device includes a hollow switch seat, a cover board for covering the switch seat, a rotatable switching piece set up inside the switch seat, a pulling piece, and a guiding piece for leading the pulling piece to reset to home position. The switch seat includes two pieces of clip tenon setup at two sides, two pieces of water-repellent for spacing out two pieces of clip tenon, and contact tags of circuit. The guiding piece possesses a separation piece near to contact tags. Pieces of water-repellent prevent moisture and hydrosphere from filtering through place of tenon. Being near to contact tags of circuit, the separation piece of the guiding piece shields contact tags to prevent contact tags from corrosion by moisture and hydrosphere. The invention reaches effect of waterproof so as to prolong service life of the switching device.

Description

【Technical field】 [0001] The invention relates to a switch device for a vehicle, in particular to a waterproof switch device for a vehicle which is suitable for switching and switching functions of a vehicle direction light. 【Background technique】 [0002] As shown in Figures 1 and 2, in order to clearly show the components, Figure 1 is a three-dimensional exploded state of a conventional switch device 1 turned ninety degrees. The switch device 1 is used to switch and switch a direction light of a vehicle (not shown), the switch device 1 includes a hollow switch base 11, a cover plate 12 for covering the bottom of the switch base 11, A switching element 13 , a pulling element 14 , and a guiding element 15 . [0003] The switch base 11 includes an upright panel 111, a top plate 112 horizontally connected to the upper edge of the panel 111, two side panels 113 extending vertically downward from opposite sides of the top panel 112 and connected to the panel 111, and a side pan...

AI Technical Summary

Problems solved by technology

[0006] 1. Without waterproof design, it is easy to short-circuit the internal conductive elements: since the tenon 118 on the side plates 113 is directly connected with the internal space of the switch base 11, when it rains or the water vapor is heavy, the moisture or moisture will It is easy to flow or infiltrate into the switch device 1, and cause a short circuit of the internal conductive elements, such as the circuit contacts 117, which cannot normally switch the direction lights, indirectly endangering driving safety

[0007] 2. The service life is not good, and it needs to be repaired or replaced frequently: although it is limited by the conductive function, the circuit contacts 117 need to be made of copper alloy, but each circuit contact 117 in the switch base 11 is Directly exposed to the atmosphere, it is easy to rust on its surface and affect its contact and conduction functions, especially in coastal areas, because the air contains high salt content, and these circuit contacts 117 are located on the windward side, more It is easy to make the circuit contacts 117 rust, causing the switch device to fail to operate normally, requiring frequent maintenance or replacement, which is likely to cause customer dissatisfaction
