Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic switches, in particular to a multi-angle closed magnetic switch contact key device. Background Art
[0002] The magnetic switch uses a magnetic component to attract a metal sheet, and presses the metal sheet to make it touch the lower power contact or detach from the upper power contact to achieve the effect of opening or closing the circuit. Compared with traditional spring switches, magnetic switches do not have the life problem of metal fatigue and have a longer service life.
[0003] The magnetic component contacts of the magnetic switch in the prior art are mostly flat disc-shaped structures. Such contacts have poor triggering properties when under pressure, resulting in a small triggering angle of the magnetic switch, which in turn limits the triggering range of the magnetic switch and affects the closing action of the magnetic switch. To this end, we propose a multi-angle closing magnetic switch contact button device. Utility Model Content
[0004] The main purpose of the utility model is to provide a multi-angle closed magnetic switch contact button device. After improvements are made to the circuit substrate and the touch-pressure membrane of the magnetic switch, the touch-pressure membrane can be adhered to the surface of the circuit substrate with the help of a surrounding adhesive strip. Then, when the touch-pressure membrane is under pressure, the secondary pressure ridges and the main pressure ridges on the surface of the touch-pressure membrane can be symmetrically stressed. When the touch-pressure membrane is under force, the magnetic component with eccentric surface concave holes and deep concave holes can be pressed with the help of a local hard sheet. The eccentric hole position design of the magnetic component has a better use effect, so that the switch button can be pressed at multiple angles on all sides to take effect, thereby improving the use trigger range of the magnetic switch contact button and effectively solving the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A multi-angle closed magnetic switch contact button device comprises a circuit substrate, a magnetic component and a touch-pressure membrane, wherein the upper plate surface of the circuit substrate is arranged and fixed with the magnetic component, and the surface of the magnetic component is pressed with an eccentric surface concave hole, and the bottom of the eccentric surface concave hole is depressed downward to press out a deep concave hole, the circuit substrate and the magnetic component surface are pressed with a touch-pressure membrane, and the lower surface of the touch-pressure membrane is integrally formed with a local hard sheet, the upper plate surface of the touch-pressure membrane away from the local hard sheet is symmetrically provided with secondary pressure ridges and main pressure ridges, and a surrounding adhesive strip for bonding the circuit substrate is fixed to the outer plate body of the touch-pressure membrane.
[0007] Furthermore, the diameter of the sheet body of the partial hard sheet is pressed over the eccentric surface concave hole; the partial hard sheet can transmit pressure to the circuit substrate at the eccentric surface concave hole after the touch-pressure membrane is pressed.
[0008] Furthermore, the secondary pressure ridges and the main pressure ridges are integrally formed on the surface of the touch-pressure membrane; the secondary pressure ridges and the main pressure ridges have good connectivity after being integrally formed with the touch-pressure membrane.
[0009] Furthermore, the hole body of the eccentric surface concave hole deviates from the central part of the magnetic component; the eccentric surface concave hole eccentrically arranged on the surface of the magnetic component can enable the magnetic component to better transmit the pressing force.
[0010] Furthermore, the strip body of the surrounding adhesive strip is integrally formed on the edge of the touch-pressure film, and the lower surface of the surrounding adhesive strip is coated with glue; the outside of the touch-pressure film can be bonded to the surface of the circuit substrate with the surrounding adhesive strip.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model improves the circuit substrate and the touch-pressure membrane of the magnetic switch, so that the touch-pressure membrane can be adhered to the surface of the circuit substrate by means of the surrounding adhesive strip. Then, when the touch-pressure membrane is under pressure, the secondary pressure convex ridges and the main pressure convex ridges on the surface of the touch-pressure membrane can bear force symmetrically. When the touch-pressure membrane is under force, the magnetic component with the eccentric surface concave hole and the deep concave hole can be pressed by means of a local hard sheet. The eccentric hole position design of the magnetic component has a better use effect, so that the switch button can be pressed at multiple angles on all sides to take effect, thereby improving the use trigger range of the magnetic switch contact button.

[0018] The diameter of the partial hard sheet 8 is pressed over the eccentric surface concave hole 3 ; the partial hard sheet 8 can transmit pressure to the circuit substrate 1 at the eccentric surface concave hole 3 after the touch-pressure membrane 5 is pressed.
[0019] The secondary pressure ribs 6 and the primary pressure ribs 7 are integrally formed on the surface of the touch-pressure membrane 5 ; the secondary pressure ribs 6 and the primary pressure ribs 7 have good connectivity with the touch-pressure membrane 5 after being integrally formed.
[0020] The hole of the eccentric concave hole 3 deviates from the center of the magnetic component 2; the eccentric concave hole 3 eccentrically arranged on the surface of the magnetic component 2 can enable the magnetic component 2 to better transmit the pressing force.
