Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a microswitch, and more particularly to a microswitch used for a mounting device of a car telephone body.

[0002]

[Prior art]

 As a structure of a micro switch used for a cradle on which a car telephone body is mounted, a structure as shown in FIG. 4 is known. FIG. 4 is a perspective view showing a schematic configuration of a mounting portion of a car telephone body. The microswitch 3 is attached to a part of the in-vehicle set using the pin 5. A lever 4 is provided on the upper surface of the micro switch 3, and when the lever 4 is pushed down on the bottom surface of the automobile telephone main body 1, a button provided on the surface of the micro switch 3 is pushed by the lever 4 and the switch of the switch is pushed. Opening operation is performed.

That is, when the car telephone main body 1 is lowered as shown by the arrow, the lever 4 on the micro switch 3 which is engaged with the on-vehicle set 2 and attached to the on-vehicle set 2 is pushed by the bottom surface of the automobile telephone main body 1. , The switch of the micro switch 3 operates and a current from a power source (not shown) flows, and the main body 1 of the telephone is charged by this current. In the case of the on-vehicle set shown in the figure, two micro switches 3 are provided, but these are provided for charging by turning on and off the positive electrode and the negative electrode of the battery at the same time. When using the micro switch, it is possible to perform the function with one micro switch.

[0004]

[Problems to be solved by the device]

 However, in the conventional micro switch, the lever 4 provided on the upper surface of the micro switch 3 directly contacts the bottom surface of the telephone body 1 as shown in FIG. 4, so that the lever 4 is hooked when the telephone is attached or detached. There was a risk that the microswitch mechanism would be damaged by being bent or bent.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a microswitch having a structure in which the force of the microswitch is not directly applied, bent, or damaged. To do.

[0006]

[Means for Solving the Problems]

 The present invention is a micro switch that performs a opening operation by pressing a button protruding from the surface, and is provided with the button so as to receive a force applied in the direction of pressing the button and transmit the force to the button. And a first member having a springy property provided in a convex shape above the surface, and an opening on the surface provided with the button, and the first member protruding from the opening. And a second member for guiding so as to surround the member.

[0007]

[Action]

 In the present invention, the lever as in the conventional microswitch is eliminated, and the first member provided instead bends in the vertical direction and pushes the button on the surface of the microswitch. Further, the springy first member operates so as to retract into the inside of the second guide member that surrounds the periphery of the first member even when it expands and contracts.

Therefore, when the main body of the telephone is placed on the in-vehicle set, the first member expands and contracts to slide into the inner surface of the second member for guiding, and at the same time, the button for opening is pushed down. become. This activates the switch. Since the lever does not project to the surface as in the past, there is no risk of being caught or bent when the phone body is placed.

[0009]

【Example】

 FIG. 1 is a perspective view showing a structure of a microswitch showing an embodiment of the present invention. 2 is an exploded perspective view thereof. In the present invention, a member 7 having a convex spring property for pressing down on the bottom surface of the telephone body 1 to receive a vertical force and transmitting this to the opening button provided on the top surface of the microswitch 3. Is provided. This member 7 is formed in a mountain shape or an R shape so as to have a spring property. To improve the mobility, the opening 7b may be formed by hollowing out the central portion as shown in the figure. The shape of the opening 7b can be modified into a square shape, a round shape, or the like.

A second member 8 having a function of guiding the member 7 is provided around the member 7. The member 8 is formed in a U shape and is mounted so as to cover the surface of the switch 3. An opening 8b is provided on the surface, and the member 7 is attached so as to be inserted into the opening 8b. The end portion 7a of the member 7 is also attached so as to dig into the inner surface of the end portion 8a of the member 8. As a result, the member 7 is pressed by the bottom surface of the telephone body 1 so that the end portion 7a of the member 7 slips into the inner surface of the end portion 8a of the member 8, and the member 7 is compressed and the inner wall surface thereof causes a switch as shown in FIG. Buttons 6a and 6b for opening operation provided on the upper surface of 3 are pressed. As a result, the opening operation is performed without using a lever as in the conventional case.

As described above, since the member 7 is provided on the upper surface of the microswitch 3 and is extended to the inner surface of the member 8 at the time of crimping, when the telephone body 1 is mounted on the vehicle-mounted set 2. The lever of the micro switch will not be bent or damaged. In the embodiment of the present invention, the structure is such that the lever 4 is removed and the members 7 and 8 are provided, but the members 7 and 8 may be attached and operated while the lever 4 is attached.

[0012]

[Effect of device]

 As described above based on the embodiment, in the present invention, a member for receiving a force applied in the direction of pressing the button of the microswitch and transmitting it to the button, and a member for guiding this member are provided. Because of the provision of the micro switch, there is an advantage that the micro switch can be operated reliably without bending or damaging the lever of the micro switch when installing or removing the telephone.
