Abstract
Disclosed is a slight-touch switch, which is composed of a base 2, a static contact piece 6 fix in the base 2, a lug 1 fixed on the base 2, a moving contact spring piece 3, a handle 4 and a cover plate 5. The utility model is characterized in that two parallel lines formed by a groove in the middle of the surface of the static contact piece 6 are contacted in tangency with a spherical surface of the moving contact spring piece 3. The shape and the installation size of the utility model can be uniform with the present slight-touch switch, but the utility model can keep effect touch in the worse environment.
Description
The utility model relates to a kind of touch-switch.
Touch-switch is made of base and the lug plate, movable contact reed, handle, the cover plate that are fixed on the static contact in the base and are fixed in base, as " metal spring leaf touch-switch " (ZL91226825, stop), " touch-switch " (ZL99239889) etc., be widely used in the various electrical equipment.Along with the continuous development of new and high technology, various electrical equipment tend to intelligent, digitlization gradually, and are increasing to the demand of touch-switch, simultaneously its reliability, stability requirement also come height more.The contact reliability of existing touch-switch mainly keeps health to guarantee by the production scene, but intrinsic electrical insulator such as workman's dandruff and human body skin secretion still exist in the dust, and uncontrollable its do not enter touch-switch inside.Existing touch-switch structure can't solve the slight resistance that " dust " is brought, and its contact reliability can't be guaranteed.
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of touch-switch is provided, and its outline overall and installing dimensions can be consistent with existing touch-switch, but can also can guarantee effective contact comparing under the harsh environmental conditions.
For achieving the above object, the solution that the utility model is taked is: a kind of touch-switch, constitute by base and the lug plate, movable contact reed, handle, the cover plate that are fixed on the static contact in the base and are fixed in base, it is characterized in that in the middle of the static contact surface two parallel lines and tangent contact of movable contact reed sphere for groove formation.
The utility model compared with prior art has following good effect:
(1) static contact of existing touch-switch is that ball point contacts with the movable contact reed, and static contact of the present utility model is that two parallel lines contact with sphere is tangent with the movable contact reed, thereby makes contact reliability obtain effective guarantee.Contact resistance is a sizable stochastic variable of dispersiveness, and its influencing factor is many and complicated.Under the constant situation of factors such as contact material, coating, improve the reliability of contact, its essence is exactly to improve the contact pressure of unit are.Its contact of existing touch-switch belongs to the disk contact, and it is multiple spot and tangent contact of movable contact reed sphere that contact-making surface of the present utility model belongs to two parallel lines, thereby has reduced contact resistance effectively.Contact resistance average out to 6.13m Ω of the present utility model, the contact resistance average out to 6.17m Ω of prior art.
(2) the utility model is littler than existing touch-switch conduction good reliability, conduction fluctuation.Conduction coefficient of variation of the present utility model is 3.13, and the conduction coefficient of variation of prior art is 3.52.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is the main pseudosection of present embodiment.
Fig. 2 is the left view of present embodiment.
Fig. 3 is an A place enlarged drawing among Fig. 1.
Fig. 4 is a base and be fixed on the static contact in the base and be fixed in the vertical view of the lug plate combining structure (clipped lug plate, amplify) of base among Fig. 1.
Among the figure: 1, lug plate, 2, base, 3, the movable contact reed, 4, handle, 5, cover plate, 6, static contact.
Shown in Fig. 1～4, a kind of touch-switch, constitute by base 2 and the lug plate 1, movable contact reed 3, handle 4, the cover plate 5 that are fixed on the static contact 6 in the base 2 and are fixed in base 2, it is characterized in that in the middle of static contact 6 surfaces two parallel lines and tangent contact of movable contact reed 3 spheres for groove formation.
Claims (1)
1, a kind of touch-switch, constitute by base (2) and the lug plate (1), movable contact reed (3), handle (4), cover plate (5) that are fixed on the static contact (6) in the base (2) and are fixed in base (2), it is characterized in that: be two parallel lines and tangent contact of movable contact reed (3) sphere of groove formation in the middle of static contact (6) surface.
