Plug-in adjustable vehicle-mounted switch, core component and manufacturing method of vehicle-mounted switch

Abstract

The invention discloses an adjustable vehicle-mounted switch of a plug-in piece, a core assembly and a fabrication method of the vehicle-mounted switch. The adjustable vehicle-mounted switch of the plug-in piece comprises a switch core assembly, wherein the switch core assembly comprises a lower shell and a plug-in pin assembly, the plug-in pin assembly comprises a plug-in pin and a static contact, the static contact is fixed at an end part of the plug-in pin, a group of plug-in holes and glue injection holes are formed in the lower shell, the glue injection holes are arranged among the plug-in holes, one end of the plug-in pin penetrates through the plug-in holes and then extends into the lower shell, a movable space is arranged in the lower shell, is used for the plug-in pin to adjust the position and communicates with the glue injection holes, and fixed glue is accumulated in the movable space and is injected after the plug-in pin is adjusted to a predetermined position. In the adjustable vehicle-mounted switch, the plug-in pin is adjustable, a related parameter can be adjusted according to demands, so that the switch is more accurate to control; and meanwhile, the plug-in pin and the shell are pasted and fixed by the fixed glue, and dual effects of waterproof sealing and connection and fixing can be achieved.

Description

technical field [0001] The invention relates to switch technology, especially vehicle switch technology. Background technique [0002] The on-board switch generally adopts the cooperation of the elastic body structure and the plastic shell to realize the movement. In the transmission device, the on-board switch plays a very important role. The working performance of the on-board switch is of great significance to the long-term safe and reliable operation of the transmission and the vehicle. [0003] After research, the applicant found that the existing on-board switches mainly have the following problems: the working environment is complex and harsh, and the connectors of the on-board switches will become loose, resulting in a decrease in waterproof performance; The plunger on the upper head is subjected to a large lateral shear force of the gear shifting mechanism, and the end face will be worn out at an accelerated rate, resulting in a change in the action position. This...

Problems solved by technology

[0003] After research, the applicant found that the existing on-board switches mainly have the following problems: the working environment is complex and harsh, and the connectors of the on-board switches will become loose, resulting in a decrease in waterproof performance; The plunger on the upper head is subjected to a large lateral shear force of the gear shifting mechanism, and the end face will be worn out at an accelerated rate, resulting in a change in the action position. This requires that the position tolerance of the switch action point be small, otherwise it is easy to cause the external gear shifting mechanism to stop. Completed, but the switch is not turned on, that is, the total stroke of the down pressure is less than the stroke of the switch action point

The parameters of the existing on-board switches are not adjustable, and the superposition error of the parts leads to the switch accuracy not meeting the expected requirements
