Description

Technical Field

[0001] The utility model relates to the field of tactile switches, in particular to a plug-in tactile switch with a large stroke. Background Technique

[0002] Tactile switches are widely used electronic components. A tactile switch generally consists of components such as pins, reed switches, and elastic buttons. The stroke of the tactile switch is mainly controlled by the structure of the elastic button. The elastic button is generally integrally formed by a cap-shaped thin shell structure and bumps provided on its upper and lower surfaces. The stroke of the elastic button is limited by the two bumps and can only work within a relatively short range. If the deformation amount is too large, stress concentration occurs at the upper and lower joints, resulting in easy damage to the elastic button. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a plug-in tactile switch with a large stroke, which includes a housing, a reed switch, an elastic button, and pins. The elastic button, the reed switch, and the pins are installed on the housing and arranged in sequence from top to bottom. The elastic button includes a cap-shaped housing and a bump integrally provided on the top surface of the cap-shaped housing. A silica gel handle is provided between the cap-shaped housing and the reed switch, and the upper part of the silica gel handle extends into the cap-shaped housing from below.

[0004] Preferably, a limiting edge is provided around the side wall of the silica gel handle, and a limiting groove adapted to the lower edge of the cap-shaped housing is provided at the top of the limiting edge. The lower edge of the cap-shaped housing extends into the limiting groove.

[0005] Preferably, a constricted neck that contracts inward is provided at the lower part of the bump.

[0006] Preferably, the housing includes a base and a cover plate, and a dust-proof cover is provided between the cover plate and the elastic button.

[0007] Preferably, a connecting edge that extends inward is provided at the bottom of the dust-proof cover, and a shrinking opening is provided at the top of the dust-proof cover, and a clamp is provided outside the shrinking opening.

[0008] Preferably, a bayonet for the clamp to snap into is provided on the constricted neck.

[0009] The beneficial effect of the utility model: Through the setting of the silica gel handle, only one bump needs to be integrally provided on the upper part of the cap-shaped housing, and the lower part is empty. The silica gel handle is arranged inside. With only one bump, during the working process, the stress is small, and there can be a larger deformation amount. Then, the reed switch is pressed through the silica gel handle, thereby realizing a larger stroke. Description of the Drawings

[0013] The following will further elaborate on the present utility model in conjunction with the embodiments given in the accompanying drawings.

[0014] Please refer to Figures 1-3 , the present utility model provides a plug-in tactile switch with a large stroke, which includes a housing 1, a reed 2, an elastic button 3 and pins 4. The elastic button 3, the reed 2 and the pins 4 are installed on the housing 1 and are arranged in sequence from top to bottom. The elastic button 3 includes a cap-shaped housing 31 and a convex block 32 integrally provided on the top surface of the cap-shaped housing 31. A silica gel handle 5 is provided between the cap-shaped housing 31 and the reed 2, and the upper part of the silica gel handle 5 extends into the cap-shaped housing 31 from below.

[0015] Through the setting of the silica gel handle 5, only one convex block 32 needs to be integrally provided on the upper part of the cap-shaped housing 31, and the lower part is empty. The silica gel handle 5 is arranged inside. There is only one convex block 32. During the working process, the stress is small and there can be a larger deformation amount. Then, the reed 2 is pressed through the silica gel handle 5, thereby realizing a larger stroke.

[0016] Furthermore, a limiting edge 51 is circumferentially provided on the side wall of the silica gel handle 5, and a limiting groove 52 adapted to the lower edge of the cap-shaped housing 31 is opened at the top of the limiting edge 51. The lower edge of the cap-shaped housing 31 extends into the limiting groove 52.

[0017] Through the setting of the limiting edge 51, the position of the silica gel handle 5 is limited, avoiding the displacement of the silica gel handle 5 and affecting the normal operation of the tactile switch. The cooperation between the limiting groove 52 and the lower edge of the cap-shaped housing 31 limits the relative position between the cap-shaped housing 31 and the silica gel handle 5, enabling the elastic button 3 and the silica gel handle 5 to maintain a relative position and keep a normal working state.

[0018] Furthermore, a constricted neck portion 33 that contracts inward is provided at the lower part of the convex block 32.

[0019] The setting of the constricted neck portion 33 reduces the connection area between the convex block 32 and the cap-shaped housing 31, reduces the stress generated when the cap-shaped housing 31 deforms, and prolongs the service life of the elastic button 3.

[0020] Furthermore, the housing 1 includes a base 11 and a cover plate 12, and a dust-proof cover 6 is provided between the cover plate 12 and the elastic button 3.

[0021] Through the setting of the dust-proof cover 6, it effectively prevents dust, water vapor, etc. from entering the housing 1, enables the tactile switch to adapt to a more complex environment, and can prolong the service life.

[0022] Furthermore, a connecting edge 61 extending inward is provided at the bottom of the dust cover 6, a shrinkage opening 62 is provided at the top of the dust cover 6, and a clamp 7 is provided outside the shrinkage opening 62.

[0023] During installation, the connecting edge 61 is clamped between the base 11 and the cover plate 12, the shrinkage opening 62 is sleeved on the necking portion 33 from top to bottom, and then fixed with the clamp 7, so as to completely seal the upper part of the tactile switch, and the sealing effect is good.

[0024] Furthermore, a bayonet 331 for the clamp 7 to snap into is provided on the necking portion 33.

[0025] The provision of the bayonet 331 can limit the position of the clamp 7, prevent the clamp 7 from shifting during operation, and make the fixation of the clamp 7 on the shrinkage opening 62 more firm and stable.

[0026] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
