Description

Button

The utility model relates to a kind of button that improves structure.

Now, the general button that uses, be a thin silicon glue transmission body to be set mostly in the button bottom, compress this silica gel transmission body by pressing down button, and then make the silica gel transmission body produce depression, make the bottom the electrically conductive graphite film be subjected to compressing of silica gel transmission body and with undermost circuit board conducting, finish the action of input information.Because the silica gel transmission body is an elastomeric objects, make this press-key structure not have the mechanical type sense of touch, and contact condition instability, and the bending place of this silica gel transmission body is subject to long-term the use and breaks, in addition, silica gel is to the sensitiveness height of temperature, easily deform, thereby cause the contact malfunction of button, very undesirable in the use.

The purpose of this utility model provide a kind of contact function-stable, accurately, the button of architecture advances.

The utility model includes pedestal, central siphon, contact, spring, plan sound shell fragment and button, it is characterized in that: pedestal wherein and panel are that injection is integrated, base interior is a hollow, with ccontaining central siphon, and be provided with at its two madial wall and set the groove of intending the sound spring leaf, its top convexes with a pipe body, and the internal diameter of this body just can put the last socket of central siphon, is provided with the ring-shaped groove that can put spring in the bottom periphery of this body;

The periphery of central siphon is provided with an outer shaft base, when central siphon runs through said base from bottom to top, this outer shaft base just can be resisted against on the inside top surface of pedestal, and the central siphon seat is provided with the pool of buffer device outside, the first half of this central siphon is provided with a cross slotted eye, so that the cross protruding pin of dashing forward and establish in the button bottom, can run through above-mentioned spring and closely be plugged in this cross slotted eye, button, pedestal and central siphon are fused, on the Lower Half madial wall of central siphon, be provided with a pair of slotted eye that is used to fix contact;

Contact is provided with a pair of elasticity clip, and the appropriate position on the lateral wall of this elasticity clip convexes with a convex body, and formed groove between two elasticity clips, just can ccontaining another spring;

The outside appropriate location of spring leaf convexes with a convex body;

Button bottom convexes with a cross protruding pin, and this cross protruding pin just can closely be plugged in the cross slotted eye that the first half of above-mentioned central siphon is provided with.

The utility model adopts the structure of particular design, make button, pedestal and central siphon connect to one, nationality helps the elastic force that presses down button and spring, central siphon can be moved in that base interior is upper and lower, thereby make the set contact in central siphon bottom compress the electrically conductive graphite film, make electrically conductive graphite film and circuit board conducting and finish the function of input information.This device has the advantages that mechanical touch sense is strong, stroke is accurate and contact action is certain.

Specifically introduce structure of the present utility model and effect below in conjunction with drawings and Examples.

Fig. 1 is an exploded view of the present utility model.

Fig. 2 is the utility model section action schematic diagram.

Consult accompanying drawing, the utility model mainly is made up of pedestal 1, central siphon 2, contact 3, spring 4, plan sound shell fragment 5 and button 6 etc.Wherein pedestal 1 is one-body molded with the plastics injection with panel 11, pedestal 1 inside is hollow, with ccontaining central siphon 2, and be provided with groove 12 at its two madial wall, intend sound shell fragment 5 to set, the top of pedestal 1 convexes with a pipe body 13, and the internal diameter of this body 13 just can put the upper tube body 21 of central siphon 2, is provided with the ring-shaped groove 14 that can put spring 62 in the bottom periphery of this body 13.

Central siphon 2 is to run through said base 1 from bottom to top, and central siphon seat 22 is resisted against on the inside top surface of pedestal 1 in addition, and central siphon seat 22 is provided with pool of buffer device 221 outside.The first half of this central siphon 2 is offered a cross slotted eye 23, and the cross protruding pin 61 that is dashed forward in button 6 bottoms to establish can run through spring 62 and closely be plugged in this cross slotted eye 23, makes button 6, pedestal 1 and central siphon 2 connect to one.On the Lower Half madial wall of central siphon 2, be provided with a pair of slotted eye 24 that is used to fix contact 3.

Contact 3 is provided with a pair of elasticity clip 31, and the appropriate position on the lateral wall of this cartridge clip button 31 convexes with a convex body 311, and formed groove 32 between two elasticity clips 31, just can putting spring 4.

During assembling, see also Fig. 2.Spring 4 is placed formed groove 32 between two elasticity clips 31 of contact 3, contact 3 is placed the Lower Half of central siphon 2, make a pair of elasticity clip 31 of contact 3, fixing is 24 li of the set a pair of slotted eyes of central siphon 2, nationality helps the elastic force of spring 4, makes central siphon 2 and contacts complete 3 and closely connect to one, again central siphon 2 is run through pedestal 1 from bottom to top, the upper tube body 21 of central siphon 2 is given prominence on pedestal 1, and be resisted against on the inside top surface of pedestal 1 with the outer shaft base 22 of central siphon 2.The first half of this central siphon 2 offers a cross slotted eye 23, the cross protruding pin 61 that makes button 6 bottoms dash forward and establish, can run through above-mentioned spring 62 and closely be plugged in this cross slotted eye 23, make button 6, pedestal 1 and central siphon 2 connect to one, when button 6 presses down, the protruding pin 61 of button 6 will compress central siphon 2, make central siphon 2 produce one and compress shell fragment 5 to bottom offset, make the convex body 51 of shell fragment 5 leave the madial wall of pedestal 1, when button 6 press down external force when removing because the restoring force of spring 62, make button 6 homings, and then drive central siphon 2 and move up, the convex body 51 of shell fragment 5 was just replied the interior sidewall surface of clashing into pedestal 1 and was sounded this moment, at this moment, because outer shaft base 22 is provided with buffer unit 221, have cushioning effect, when making central siphon 2 with pedestal 1 collision, do not have not should sound generating.
