Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] refer to Figure 1~Figure 4 As shown, the novel onboard switch of the present invention is composed of a pin seat and a soft pin, and the pin seat is composed of a base plate 1, a lower metal shrapnel 4, and an upper metal shrapnel 5, and the base plate 1 is made of an insulating material; The lower metal shrapnel 4 is in the shape of a rectangular sheet and is installed on the left side of the substrate 1; the upper metal shrapnel 5 is Ω-shaped, and the right side of the upper metal shrapnel 5 is installed on the right side of the substrate 1. When there is no external force, the upper metal shrapnel 5 The left side of the shrapnel 5 is in natural contact with the lower metal shrapnel 4. After the left side of the upper metal shrapnel 5 contacts the lower metal shrapnel 4, a pin hole is formed between the upper metal shrapnel 5 and the lower m...

Abstract

The invention discloses a novel onboard switch composed of a plug pin base and a flexible plug pin. The plug pin base is composed of a substrate, a lower metal elastic sheet and an upper metal elastic sheet. The substrate is made of insulated materials. The lower metal elastic sheet is of a rectangular thin sheet shape and is installed on the left side of the substrate. The upper metal elastic sheet is of an n shape. The right side of the upper metal elastic sheet is installed on the right side of the substrate. When no external force is exerted, the left side of the upper metal elastic sheet makes natural contact with the lower metal elastic sheet, so that a plug pin hole is formed between the upper metal elastic sheet and the lower metal elastic sheet. The flexible plug pin is composed of a front plastic portion and a rear metal portion. The tail portion of the plastic portion is fixedly connected with the head portion of the metal portion in a seamless mode. When the left side of the upper metal elastic sheet makes contact with the lower metal elastic sheet, the head portion of the plastic portion can extend into the plug pin hole between the upper metal elastic sheet and the lower metal elastic sheet. The novel onboard switch has the advantages of being large in borne current, applicable to occasions with the strict requirement for the size and the weight, and capable of serving as not only a circuit power supply switch but also a motion detection switch.

Description

technical field [0001] The invention relates to a novel board-mounted switch which can be used not only as a circuit power supply switch but also as an action detection switch. Background technique [0002] At present, domestic switches with reliability indicators and life indicators are relatively large. Whether it is a micro switch, a button switch, or a button switch, the smallest is 13×5.1×11.2mm. If you want to use this type of switch as a circuit power switch Or motion detection switch, you must design the installation structure for this purpose, the volume is larger, and the current that this kind of small volume switch can withstand is also limited, the maximum does not exceed 5A. The smallest printed circuit board-mounted micro switch among ordinary civil switches at home and abroad can only be used as a human-made touch detection switch, which bears a small current and cannot be pressed for a long time. Contents of the invention [0003] The technical problem to...
