Abstract
The utility model provides a soft-touch voiceless switch structure which comprises an insulation body, a movable pressing body and a fixing terminal which are respectively arranged on the top end of the insulation body and the bottom thereof. A transmission soft colloid is arranged above a central terminal of the insulation body and inlaid in a positioning groove of the movable pressing body; both sides of the transmission soft colloid are respectively provided with supporting pins the surfaces of which are coated with electrically conductive carbon diaphragm or electrically conductive silicone; the contact part of the transmission soft colloid and the fixing terminal is provided with a layer of electrically conductive carbon diaphragm or a layer of electrically conductive silicone and matched with the fixing terminal. The soft-touch voiceless switch structure acts on the movable pressing body through an external force and the movable pressing body then is pressed down to convey an acting force to the transmission soft colloid which is then deformed and pressed down and meanwhile, the layer of electrically conductive carbon diaphragm or the layer of electrically conductive silicone is connected with the fixing terminal so as to ensure that a circuit forms a loop; after the completion of the period of external force action, the transmission soft colloid rebounds to cause the layer of electrically conductive carbon diaphragm or the layer of electrically conductive silicone to be disconnected with the fixing terminal and the circuit loop to be cut. The soft-touch voiceless switch structure has no noise when in application, long service life and strong practicability and produces no frequency interference.
Description
Technical field
The utility model relates to a kind of switching device, refer to especially a kind of be applied on the electronic equipment can the noiseless construction of switch of jamproof soft-touch type.
Background technology
Traditional regular tap is shown in the skiagraph of the vertical view of Fig. 1 and Fig. 2, it generally is made of following part: be provided with the insulating body 1 that contains the space, be arranged at the metal fixed terminal 2 and metal fixed terminal 3 of bottom, the evagination activity is pressed by body 4, is pushed driving section 5 and metal driving portion 6.During work, evagination activity is under external force pressed and is pressed down by body 4, force transfer is to pushing driving section 5, again power is implemented in metal driving portion 6, metal driving portion 6 stress deformations are pressed down, thereby link the metal fixed terminal 2 and metal fixed terminal 3 that are arranged at the bottom, make circuit loop conducting running; After the external force action period finished, the 6 natural resiliences of metal driving portion disconnected metal driving portion 6 and metal fixed terminal 2 that is arranged at the bottom and metal fixed terminal 3, and circuit loop cuts off.Its design defect is can produce ear-piercing snap sound when 6 resiliences of metal driving portion, and can produce the stress concussion in metal driving portion 6 springback processes, disturbs thereby produce wave frequency.
Summary of the invention
The purpose of this utility model is to solve the design deficiency of conventional switch, propose a kind of noiseless, can reduce the injury of human that metal driving portion produces owing to stress amplitude and the noiseless construction of switch of soft-touch type of mechanical wear anti-interference and greatly.
For reaching above-mentioned technical purpose, the noiseless construction of switch of the utility model soft-touch type comprises an insulating body, be located at the activity pressure on insulating body top and press body and insulating body fixed bottom, above the insulating body center terminal, locate to be provided with and the movable transmission flexible glue body that mates mutually by body of pressing, this transmission flexible glue body is entrenched in movable the pressure in the location notch of pressing the body middle part, the both sides of described transmission flexible glue body are provided with the feet of surface-coated conductive carbon film or electric silica gel, itself and transmission flexible glue body form similar vaulted shape, the contact site of transmission flexible glue body and fixed terminal is provided with a conductive carbon rete or conductive silicon glue-line, and itself and insulating body fixed bottom are complementary.
Further measure is: the described transmission flexible glue body that is installed on the center terminal top is any type in the flexible glue material, and most preferably adopts silica gel flexible glue body or silica gel flexible glue body.
Movable under external force pressure of the noiseless construction of switch of this soft-touch type presses down by body, force transfer is to transmission flexible glue body, transmission flexible glue body stress deformation presses down, contact conductive carbon rete partly or conductive silicon glue-line and be arranged at the binding of fixed bottom, be communicated with, thereby make circuit loop conducting running.After the external force action period finished, the then natural resilience of transmission flexible glue body conductive carbon rete or conductive silicon glue-line and fixed terminal are disconnected, thereby circuit loop cut off.
Compared to old technology, noiseless construction of switch of the present utility model is realized the clutch action of switch in entire circuit is used by inner transmission flexible glue body, in the stressed course of action of transmission flexible glue body, can make whole process become quiet noiseless because of its materials attribute, and the amplitude that transmission flexible glue body can be stopped to be produced by stress oscillation in springback process fully disturbs, can be general to the high frequency field, and transmission flexible glue body has higher cycle life than the metal driving portion that conventional switch adopts.
The beneficial effects of the utility model are:
1, noiseless, life-span long, can reduce the mechanical fatigue that movable contact produces owing to stress amplitude greatly.
2, feel is light, the frequency interferences of having no way of and producing in stress amplitude.
3, production efficiency height, cost is low, can significantly reduce the parts loss in the production process.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done more detailed explanation.
Fig. 1 is the schematic top plan view of regular tap.
Fig. 2 is the vertical section schematic diagram of regular tap.
Fig. 3 is a plan structure schematic diagram of the present utility model.
