Abstract
The utility model discloses a pedal switch, which comprises a conductive elastic cover and a circuit board; wherein, the circuit board, which is embedded inside the conductive elastic cover; is provided with a connecting port and a contact; the connecting port can be connected with a wire; the contact can be contacted with the conductive elastic cover; a raised circular ring which can be contacted with the circuit board is arranged on the inner surface of the conductive elastic cover; and an annular assembling bayonet in which the pedal switch can be assembled is arranged on the outer surface of the conductive elastic cover. The utility model achieves a water-proofing effect with lower cost, the elasticity of the conductive elastic cover is good, the generated mechanical abrasion is less during use, the service life is prolonged, and both assembly and use are simple and convenient.
Description
Technical field
The utility model relates to a kind of switch, particularly relates to a kind of foot switch.
Background technology
The structure of most of foot switchs both domestic and external is very similar at present, all comprise likes such as pedal, sensitive switch, base, spring and pin, pedal tramps with one's feet during use, shell touches the movable top lever apparatus on the interior sensitive switch of foot switch, the armature contact on the reed and the closing of contact that is fixed on the sensitive switch, thus circuit connected.When unclamping pedal, pedal relies on the spring strength below it to restore to the original state, and sensitive switch movable top lever apparatus restores to the original state simultaneously, and the contact disconnects in the sensitive switch, and circuit cuts off thereupon.The foot switch mechanical wear of this structure is big, and since its design feature will to reach the waterproof effect cost higher.
The utility model content
The purpose of this utility model is to provide a kind of foot switch, can reach waterproof effect at lower cost, and installation and use are all very convenient, and very durable, and useful life is very long.
For achieving the above object, the technical solution of the utility model is: a kind of foot switch, comprise the electrically conductive elastic cover of dome-type and round wiring board, described wiring board is embedded in the inside of electrically conductive elastic cover, wiring board is provided with and is used to the contact that connects the connector of electric wire and be used for contacting with the electrically conductive elastic cover, the inner surface of described electrically conductive elastic cover is provided with and is used for the projection annulus that contacts with wiring board, and the outer surface of electrically conductive elastic cover is provided with the annular that is used to install foot switch bayonet socket is installed.
Described electrically conductive elastic cover is made by the elastomeric material of conduction.
Contact on the described wiring board is grid and distributes, and guarantees to contact with the effective of electrically conductive elastic cover.
During use, the utility model is installed in desired location, couple a wire to the connector on the wiring board, when riding on the electrically conductive elastic cover, the electrically conductive elastic cover is because of the distortion downwards that is under pressure, projection annulus on the electrically conductive elastic cover inner surface contacts with wiring board, makes the grid contact conducting on the wiring board, connects circuit; When pin left the electrically conductive elastic cover, electrically conductive elastic cover pressure was removed, and restored to the original state, and the projection annulus on the electrically conductive elastic cover inner surface also separates with wiring board, and the grid contact on the wiring board disconnects thereupon, cut off circuit.
Wiring board is provided with the comparison drive circuit, can overcome the shortcoming of the big and consistency difference of non-metallic conducting material impedance, and the antijamming capability of enhancing foot switch.
Compared with prior art, the utility model has following beneficial effect: the utility model realizes reaching waterproof effect at lower cost, and electrically conductive elastic cover elasticity is fine, and the mechanical wear that produces during use is very little, prolonged useful life, installation and use are all very simple and convenient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model when circuit disconnects;
Fig. 2 is the structural representation of the utility model when circuit is connected;
Fig. 3 is the utility model wiring board net distribution contact schematic diagram.
Embodiment
Foot switch as depicted in figs. 1 and 2, comprise electrically conductive elastic cover 1 and wiring board 2, wiring board 2 is positioned at the inside of electrically conductive elastic cover 1, wiring board 2 be provided be used to connect the connector 2a of electric wire and be used for contacting with electrically conductive elastic cover 1 be the contact (as Fig. 3) that grid distributes, the inner surface of electrically conductive elastic cover 1 is provided with projection annulus 1b, the outer surface of electrically conductive elastic cover 1 is provided with the annular that is used to install foot switch bayonet socket 1a is installed, and electrically conductive elastic cover 1 is made by conductive rubber.
During use, the utility model is installed in desired location, electric wire 3 is connected to connector 2a on the wiring board 2.When riding on electrically conductive elastic cover 1, as shown in Figure 2, electrically conductive elastic cover 1 is because of the distortion downwards that is under pressure, and projection annulus 1b contacts with wiring board 2, makes on the wiring board 2 grid contact conducting, the connection circuit; When pin left electrically conductive elastic cover 2, as shown in Figure 1, electrically conductive elastic cover 2 pressures were removed, and restore to the original state, and projection annulus 1b also separates with wiring board 2, and 2 grid contact disconnects thereupon on the wiring board, cuts off circuit.
Also can be provided with the output of comparison drive circuit at wiring board in addition, owing to be to contact by conductive rubber, conductive rubber is along with the aging of use has certain resistance, thus the pressure drop that conductive rubber can produce when foot switch is connected, and influence is in the low level signal output of foot switch on-state.Set comparison reference by drive circuit relatively, guarantee the low level signal output of foot switch on-state, can overcome the shortcoming of the big and consistency difference of non-metallic conducting material impedance like this, and the antijamming capability of enhancing foot switch.
