Embodiment Construction

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

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

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 on-board switch which can be used as both a circuit power supply switch and an action detection switch. Background technique [0002] At present, switches with reliability indicators and life indicators in China are relatively large in size. Whether it is a micro switch, a button switch, or a toggle switch, the smallest one is 13×5.1×11.2mm. If you want to use this type of switch as a circuit power supply switch Or the action detection switch, the installation structure must be designed for this purpose, and the volume is larger, and the current that such a small-volume switch can withstand is also limited, and the maximum does not exceed 5A. The smallest printed circuit board-mounted micro switch among ordinary civil switches at home and abroad, generally can only be used as an artificial touch detection switch, which bears a small current and cannot be pressed for a long time. SUMMARY OF THE INVENTION [0003] The ...
