Abstract

The utility model relates to a toppling on-off micro-switch which comprises: a casing, wherein the upper part of the casing is provided with a first cavity, and the lower part of the casing is provided with a terminal supporting member which is sheathed with the lower part of the casing. A second cavity is arranged in the terminal supporting member. A cavity channel is arranged between the first cavity and the second cavity to communicate with first cavity with the second cavity. A heavy ball is arranged in the first cavity. The bottom of the terminal supporting member is provided with input terminals, and the lateral part of the terminal supporting member is provided with a first output terminal and a second output terminal which extend into the second cavity, wherein buttons are arranged in the cavity channel and the second cavity. One end of the button and one side of the terminal supporting member are movably hinged, and the other end of the button extends into the cavity channel to match with the heavy ball in a contact mode. A contact bridge spring lamination is arranged under the button; one end of the contact bridge spring lamination and the other side of the terminal supporting member are movably hinged, and the other end of the contact bridge spring lamination is inserted between the end points of the first output terminal and the second output terminal. The utility model has the advantages of reasonable structure and simple driving section, so the safety coefficient and the safety performance of the switch is greatly improved.

Description

A kind ofly topple over the break-make sensitive switch

Technical field:

The utility model relates to a kind of electric apparatus control apparatus, particularly a kind ofly topples over the break-make sensitive switch.

Technical background:

At present topple over the break-make sensitive switch being used on the market to prevent that electrical equipment and simple and easy machinery from shielding when toppling over; having a kind of is the formula of heavily cutting or polish jade with an emery wheel; the heavily stone roller of switch is exposed outside; being subjected to the external environment factor affecting easily causes malfunctioning; and the angle of toppling over action is different widely different because of direction; another kind is the anti-dumping switch that is provided with by lever principle; totally enclosed type anti-dumping switch as the patent No. 200320120575.7; also there is following defective; the transmission link of operating mechanism is too many; malfunctioning phenomenon appears easily; the action transfer mode of this patent is: steel ball → pallet → lever → sensitive switch; because transmission link is many; often jagged or fault makes malfunctioning switch because of the part of one of them link; and the resilient pressure of loss switch is too many, and switch causes not enough restoring force and the fault that can not disconnect easily when resilience.

Summary of the invention:

The purpose of this utility model provides a kind of transmission link rational in infrastructure, inner and simply topples over the break-make sensitive switch, to overcome the deficiencies in the prior art.

For realizing this purpose, the utility model provides following technical scheme: comprising: housing, described housing top is provided with first cavity, the bottom is provided with terminal supporter, described terminal supporter and described lower housing portion socket, be provided with second cavity in the described terminal supporter, being provided with cavity between described first cavity and second cavity is communicated with, be provided with heavy ball in described first cavity, described terminal supporter bottom is provided with input terminal, sidepiece is provided with first lead-out terminal and second lead-out terminal, described first lead-out terminal and second lead-out terminal extend into second cavity, wherein, in the described cavity and second cavity, be provided with button, an end of described button and described terminal supporter one side activity hinge joint, the other end extends into cavity and heavy ball contact matching, be provided with below button and touch the bridge shell fragment, describedly touch the movable hinge joint of bridge shell fragment one end and terminal supporter opposite side, the other end that touches the bridge shell fragment inserts between the end points of described first lead-out terminal and second lead-out terminal.

The utility model is rational in infrastructure, utilizes the direct pressing button of steel ball, overcome that multiple transmission is broken down easily or the resilience force loss and malfunctioning, transmission link is comparatively simple, improves the safety factor and the security performance of switch greatly.

The utility model will be further described below in conjunction with accompanying drawing:

Embodiment:

Shown in Fig. 1-2, the utility model comprises: housing 1, described housing 1 top is provided with first cavity, the bottom is provided with terminal supporter 2, described terminal supporter 2 and the 1 bottom socket of described housing, be provided with second cavity in the described terminal supporter 2, being provided with cavity between described first cavity and second cavity is communicated with, be provided with heavy ball 3 in described first cavity, described terminal supporter 2 bottoms are provided with input terminal 4, sidepiece is provided with first lead-out terminal 51 and second lead-out terminal 52, described first lead-out terminal 51 and second lead-out terminal 52 extend into second cavity, wherein in the described cavity and second cavity, be provided with button 6, one end of described button 6 and described terminal supporter 2 one side activities hinge joint button 6, the other end extends into cavity and heavy ball contact matching, is provided with to touch bridge shell fragment 7 below button 6 is joined, a described end and the movable hinge joint of described terminal supporter 2 opposite sides of touching bridge shell fragment 7, the other end that touches bridge shell fragment 7 inserts between the end points of described first lead-out terminal 51 and second lead-out terminal 52.When under normal circumstances, heavy ball 3 weight buttons 6, gravity by button 6, touch bridge shell fragment 7 other end that touches bridge shell fragment 7 contacted with first lead-out terminal 51, make circuit turn-on, electrical equipment or simple and easy machinery normally use; When electrical equipment or simple and easy machinery are toppled over, heavy ball 3 departs from, the disconnection that contacts with button 6, action of gravity this moment disappears, and under the restoring force effect of touching bridge shell fragment 7, the other end and first lead-out terminal 51 that touch bridge shell fragment 7 disconnect, and contact with second lead-out terminal 52, reach and utilize translation-angle to replace the function of break-make, play to topple over and afterwards cut off the purpose that appliances power source or connection signal reach safety warning, ensured the safety of electrical equipment and simple and easy machinery.

Bottom at described shell 1 also can be provided with sulculus, and power assistant spring 8 is set in the sulculus, and described power assistant spring 8 directly acts on button 6, is used for the action of gravity of auxiliary heavy ball 3.

The utility model can be widely used on household electrical appliance such as electric heater, electric heating oil lamp and the simple and easy plant equipment.
