Abstract
The utility model discloses a waterproof tact switch, mainly solving the problem that the traditional waterproof tact switch is poor in waterproof effect. The waterproof tact switch is characterized in that a curve section (3) is arranged at the inner edge of a joint part between a metal terminal (2) and a plastic base (1), and the outer edge of the metal terminal (2) is uneven; and a contact end (7), stretching into the plastic base (1), of the metal terminal (2) is bent. According to the waterproof tact switch, a water creep distance between the contact terminal (7) and the outer part of the plastic base (1) is increased, the waterproof performance is improved and a waterproof effect is good.
Description
Technical field
The utility model relates to a kind of electronic switch, is specifically related to a kind of waterproof touch-switch.
Background technology
The waterproof touch-switch is a kind of electronic switch commonly used, presses shift knob during use gently and just can make switch connection, and switch breaks off when unclamping hand, and stressed springing realizes break-make to its internal structure by metal clips.The classification of waterproof of waterproof touch-switch generally is divided into IP0～IP8 totally 9 grades, and classification of waterproof was at least the IP6 level when the higher occasion of waterproof requirement was used.Existing waterproof touch-switch mainly is made up of terminal, base, shell fragment, gland, gummed paper, silica gel and button, and terminal and base are injected into one, and the terminal top is provided with shell fragment, gland, gummed paper, silica gel and button successively.Because metal terminal is different with the thermal coefficient of expansion of plastic feet; Metal terminal is a sheet shape pin shape, is prone to very little gap between the inward flange of metal terminal and the plastic feet, and water can penetrate in the plastic feet from this gap location lentamente; The metal terminal linear pattern extend in the plastic feet; Climb water apart from weak point, waterproof effect is poor, is difficult to reach the anti-water quality standard of the above grade of IP6.
The utility model content
In order to overcome the deficiency of existing waterproof touch-switch waterproof effect difference, the utility model provides a kind of waterproof touch-switch, and this waterproof touch-switch has increased climbs the water distance in metal terminal and the plastic feet, has improved water resistance, good water-proof effect.
The technical scheme of the utility model is: this waterproof touch-switch comprises plastic feet and metal terminal, and metal terminal and plastic feet are injected into one, and metal terminal is a sheet shape pin shape, and the part inward flange that metal terminal engages with plastic feet is provided with curved section.
Described curved section is positioned at the corner of metal terminal and inwardly concaves.
The recessed degree of depth of described curved section is at least 0.8mm.
The outward flange of described metal terminal is provided with convexity or groove.
The utlity model has following beneficial effect: owing to take such scheme, increased and climbed the water distance between metal terminal and the plastic feet, improved water resistance, good water-proof effect.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Accompanying drawing 2 is A-A structure cutaway views among Fig. 1.
Accompanying drawing 3 is structure expanded views of terminal 2 among Fig. 2.
1-plastic feet among the figure, the 2-metal terminal, the 3-curved section, 4-gummed paper and silica gel, the 5-button, the 6-gland, the 7-tip side, 8-is protruding, the 9-groove.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Combine Fig. 2, shown in Figure 3 by Fig. 1, this waterproof touch-switch comprises plastic feet 1 and metal terminal 2, and metal terminal 2 tops are provided with gummed paper and silica gel 4 and button 5 successively, and button 5 is spacing by gland 6.Metal terminal 2 is injected into one with plastic feet 1, and metal terminal 2 is a sheet shape pin shape, and the part inward flange that metal terminal 2 engages with plastic feet 1 is provided with curved section 3, and the outward flange of metal terminal 2 is uneven; The tip side 7 that metal terminal 2 stretches in the plastic feet 1 is bending.In technique scheme, effectively increased and climbed the water distance between metal terminal 2 and the plastic feet 1, improved water resistance, good water-proof effect.When waterproof test, this waterproof touch-switch is immersed 20 minutes hydraulic pressure 5cm in the 100 degree boiling water, water can not enter into the inside of waterproof touch-switch or dry outside water stain test insulation resistance greater than 100M Ω.
Combined shown in Figure 3ly by Fig. 2, the curved section 3 of inward flange is positioned at the corner of metal terminal 2 and inwardly concaves on the described metal terminal 2.Compact conformation need not change original plastic feet 1 size, and injection moulding adds still can use original mould man-hour.
Combined shown in Figure 3ly by Fig. 2, the recessed degree of depth of described curved section 3 is at least 0.8mm.This size is confirmed by the polycrystalline substance size of plastic feet 1.
Combine by Fig. 2 shown in Figure 3, the outward flange of metal terminal 2 be provided with protruding 8 with groove 9.Convexity 8 has increased with groove 9 effectively climbs the water distance, has improved water resistance.
Claims (4)
1. waterproof touch-switch; Comprise plastic feet (1) and metal terminal (2); Metal terminal (2) is injected into one with plastic feet (1); Metal terminal (2) is a sheet shape pin shape, it is characterized in that: the part inward flange that metal terminal (2) engages with plastic feet (1) is provided with curved section (3), and the outward flange of metal terminal (2) is uneven; The tip side (7) that metal terminal (2) stretches in the plastic feet (1) is a bending.
2. waterproof touch-switch according to claim 1 is characterized in that: described curved section (3) is positioned at the corner of metal terminal (2) and inwardly concaves.
3. waterproof touch-switch according to claim 2 is characterized in that: the recessed degree of depth of described curved section (3) is at least 0.8mm.
4. according to claim 1,2 or 3 described waterproof touch-switchs, it is characterized in that: the outward flange of metal terminal (2) is provided with convexity (8) or groove (9).
