Abstract

The utility model relates to a micro force switch, which is composed of a bar-shaped copper sheet 1, an L-shaped copper sheet 2 having one tip end, a shell body 3 and a cover 4, wherein, the shell body 3 is oblong and is composed of insulating materials, the bottom wall of the shell body is provided with two columns 5, the lower part of one of two short walls is provided with a first seam, and the upper and the lower parts of the other short wall are respectively provided with a second seam and a third seam. The lower end of the copper sheet 1 is inserted in the first seam for fixation, and the other end of the copper sheet 1 is extended out of the second seam round the columns. The copper sheet 2 is fixed to the third seam, and the tip end of the copper sheet 2 is pointed to the copper sheet 1. The extended end of the bar-shaped copper sheet is pressed down slightly, and the point contact between the bar-shaped copper sheet and the L-shaped copper sheet can be realized. When external force is eliminated, the bar-shaped copper sheet can restore to a former state via restoring force. The utility model having small volume, high durability and reliability is suitable for toys, etc.

Description

Micro force switch

The utility model relates to a kind of little power switching device, can specifically be used for the switch of electronic toy sound equipment or the continuous sexual act of connection.

Have the electronic toy of continuous sexual act of connection or sound equipment, for example the marble machine when marble is rolled to a certain position, can touch one group of switching device, and its positional information is passed to integrated circuit, and (I C), makes it send the sound or the continuous sexual act of connection etc.Usually, the device all formed of this switching device by the insulant between two long copper pieces and copper sheet.Such structure, it is bigger to take up room, and is not incorporate; Be difficult for installing, and need bigger pressure just can make its contact contact.For example, the Japanese toy TOMY structure (Fig. 1) of producing is the same.Among the figure, 1,2 is copper sheet, and 3 is insulant.If the object of the touch switch on the toy is light (for example 5g), volume is again little, can not be applied on the described toy.

As long as the purpose of this utility model overcomes above-mentioned shortcoming exactly, provides a kind of the switch that very little power just can be connected.

The advantage of little power switching device of the present utility model is with simple and effective functional structure, can be used for that volume is little, in the light electronic toy and similar appliances of induction.Described little power switch is an integral body, easily installs; The angle of bend of flexible member is little, and the life-span is long; And it is safe and reliable.

Below in conjunction with accompanying drawing in detail, the utility model is described in detail.

Fig. 1 is a kind of traditional construction of switch;

Fig. 2 is a front view of the present utility model;

Fig. 3 is a side sectional view of the present utility model.

Consult Fig. 2,3. Little power switch of the present utility model comprises:

-bar shaped elastic copper sheet (1) is used as one of contact of switch;

-L shaped copper sheet (2), an end is pointed, as another contact;

-housing (3), make by insulating material, it is a rectangle of forming by four Bian Bi and a diapire, two cylinders (5) are arranged on the diapire, the on line of this two cylinder is parallel to the Chang Bianbi of described housing, open one first seam in the bottom of one of two minor face walls, on another shortwall, the bottom has second seam and the 3rd seam, make the end insertion first seam back of bar shaped elastic copper sheet (1) fixing, the other end is walked around cylinder and is stretched out from second seam, make and have the restoring force that presses down, it is fixing that one end of L shaped copper sheet (2) inserts the 3rd seam back, its tip is clipped between shortwall and the cylinder, points to bar shaped copper sheet (1), makes the sheet of bar shaped copper stretch out housing parts and slightly descends the pressure energy contact tip;

-lid (4) is also made by insulating material, covers housing (3), prevents that bar shaped copper sheet (1) and L shaped copper sheet (2) from dropping out.

From the top down during the external part of press strip shape copper sheet (2), can contact the tip of L shaped copper sheet (2) as little power, realize the some contact, switch conduction.When downforce was cancelled, because this copper sheet (1) other end is fixed in first seam, cylinder (5) and top wall made this elastic copper sheet (1) have restoring force, restore to the original state, and switch disconnects.

In the utility model, can regulate thickness, the width of bar shaped copper sheet (1), or adopt suitable flexible copper sheet according to the size of downforce, realize best performance.

Claims

1, a kind of little power switching device is characterized in that, comprising:

-bar shaped elastic copper sheet (1) is used as one of contact of switch;

-L shaped copper sheet (2), an end is pointed, as another contact of switch;

-housing (3), make by insulating material, the rectangle of forming by four Bian Bi and a diapire, two cylinders (5) are arranged on the diapire, the on line of this two cylinder is parallel to the Chang Bianbi of described housing, open one first seam in the bottom of one of two minor face walls, on another shortwall, the bottom is opened second seam and the 3rd seam respectively, make bar shaped elastic copper sheet (1) one end insert the first seam back and fix, the other end is walked around cylinder and is stretched out from second seam, makes to have the restoring force that presses down, it is fixing that one end of L shaped copper sheet (2) inserts the 3rd seam back, its tip is clipped between shortwall and the cylinder, points to the bar shaped copper sheet, can contact described tip after making the bar shaped copper sheet stretch out housing parts slightly to press down;

-lid (4) is made by insulating material, covers housing (3), prevents that bar shaped copper sheet and L shaped copper sheet from dropping out.
