Abstract

The utility model belongs to the technical field of the switch application. Two dish-shaped conducting strips are arranged in an insulated shell, and an interstice is arranged between the conducting strips. A conductive ball is arranged between the two conducting strips. The two conducting strips are connected with electrodes, and at least four electrodes are additionally arranged on a plane in the insulated shell. The conductive ball is positioned in the insulated shell, and is simultaneously covered two adjacent electrodes positioned in the insulated shell. The structure overcomes the disadvantages of complex structure and low sensitivity of the traditional switch. The utility model is a switch which can indicate the unbalance state in a plurality of directions with simple structure and higher sensitivity.

Description

Unbalanced switch

The utility model belongs to the switch application technical field.

Traditional switch for push, touch or inductance type switch, keep the instrument or the device of balance for needs, need complex apparatus or circuit to be controlled, instrument or device are in time reported to the police when unbalance, and this equipment mostly is unidirectional bascule, complex structure, and result of use is undesirable.

Therefore, the purpose of this utility model is: Unbalanced switch a kind of simple in structure, multi-faceted is provided.

The utility model adopts and be provided with the conducting strip 3 of plate-like and the conducting strip 4 of plate-like in insulation shell 1, gapped between the conducting strip of two plate-likes, be connected to electrode 2 on the conducting strip 3 of plate-like, be connected to electrode 5 on the conducting strip 4 of plate-like, conducting sphere 6 is arranged between the conducting strip of two plate-likes, one end of electrode is positioned at insulation shell, at least 4 electrode pairs should be located on the interior same plane of insulation shell, be provided with conducting sphere in the insulation shell, conducting sphere can be carried out lid simultaneously and be positioned at insulation shell, two adjacent electrodes, conducting sphere 6 is for mercury ball or for steel ball or for being coated with the conducting sphere of gold or silver.Said structure has been realized the purpose of this utility model.

The utility model is simple in structure, be easy to make, and highly sensitive, wide application can be widely used in earthquake prediction system, industrial system, and the military project application system is specially adapted to prevent the alarm of driver's drowsiness.

Below in conjunction with Figure of description two most preferred embodiments of the present utility model are described.

Fig. 1 is the schematic diagram of the utility model embodiment 1

Fig. 2 is the schematic top view of the utility model embodiment 2

Embodiment 1, (as shown in Figure 1) use insulating material, plastics etc. for example, make insulation shell 1, the conducting strip 3 of plate-like and the conducting strip 4 of plate-like are installed in it, the conducting strip central point of plate-like is recessed gradually, its face of deciding what is right and what is wrong can be parabola shaped, also can be semicircle, the conducting strip 3 of plate-like, correspondence is arranged in the insulation shell about in the of 4, leave the gap between two conducting strips, the diameter that makes conducting sphere greater than the gap between the conducting strip edge of plate-like less than the gap between the conducting strip central point of two plate-likes, as the gap between the conducting strip central point of two plate-likes is 2 millimeters, conducting sphere is 1.5 millimeters, and the gap between two conducting strip edges of plate-like then is 1 millimeter, just can make conducting sphere link the conducting strip 3 of two plate-likes simultaneously in two conducting strip edge zones of plate-like, 4.

Receiving electrode 2 on the conducting strip 3 of plate-like, receiving electrode 5 on the conducting strip 4 of plate-like, in order to connect extraneous power supply, place with mercury on the conducting strip of plate-like and can be used as conducting sphere 6, also available steel ball or be coated with gold or silver conducting sphere, to guarantee that conducting sphere when contacting the conducting strip edge of two plate-likes, has excellent conducting performance.

During use, Unbalanced switch is used for control appliance, conducting strip 4 balancing equipments of plate-like are placed, at this moment, conducting sphere 6 is positioned at the central point of the conducting strip 4 of plate-like, conducting sphere does not contact with the conducting strip 3 of plate-like, switch disconnects, when equipment or device disequilibrium, make also disequilibrium thereupon of Unbalanced switch, this unbalance be not to be subjected to the orientation restriction, this inclination causes the conducting sphere 6 on the conducting strip 4 that is positioned at plate-like to roll to the conducting strip edge of two plate-likes, because the diameter of conducting sphere is greater than the gap between the conducting strip of two plate-likes, two conducting strips of conducting sphere contact, Unbalanced switch is connected, and warning device gets final product work, when equipment or device balance, conducting sphere resets, and switch disconnects again.

Embodiment 2(is as shown in Figure 2) in insulation shell, at least 4 electrode pairs should be positioned on the plane of insulation shell, the quantity of electrode is equipment as required, usually select 4-12 root electrode for use, be distributed in by certain distance on the plane of insulation shell, an end of every electrode is positioned at insulation shell, and the other end is positioned at outside the insulation shell, be provided with the conducting sphere 6 that water silvery is done in the insulation shell, conducting sphere 6 can be carried out two adjacent electrodes that lid is positioned at insulation shell simultaneously.As carry out and cover Fig. 2 and give electrode 7 and the electrode 8 that shows.The effect of this structure is that when the Unbalanced switch balance, the conducting sphere that the water restriction is done is positioned at the insulation shell bottom and does not disconnect with any electrode contact-making switch, during the switch disequilibrium, make mercury ball flow to the edge zone, and contact two electrodes simultaneously, make the electric current of two power supplys connect switch connection.This structure can be indicated unbalance orientation or direction.

The utility model is simple in structure, highly sensitive, can the unbalance direction of multi-faceted indication, and be a kind of comparatively desirable Unbalanced switch.
