Abstract
A dust-proof water-proof tact switch mainly solves the problems that a conventional 10*10 or 12*12 dust-proof water-proof tact switch is provided with a metal terminal having short water-climbing distance and bad waterproof effect. The tact switch is characterized in that curve sections (3) are arranged between the two ends of a first connecting sheet (21) and side contact ends (22); the curve sections (3) are also arranged between the two ends of a second connecting sheet (23) and a center contact end (24); the curve sections (23) are arranged in the entity of a plastic base (1); and the side contact ends (22) extend out along the center of the first connecting sheet (21) and bend towards the two sides of the center contact end (24) to extend into the middle part of the plastic base (1). According to the dust-proof water-proof tact switch, the water-climbing distance of the metal terminal on the two sides of the plastic base is longer, the water-proof performance is improved and the water-proof effect is good.
Description
Technical field
The utility model relates to a kind of touch-switch, is specifically related to a kind of dustproof and waterproof touch-switch.
Background technology
Touch-switch is a kind of standard electronic switch; It is 10*10mm or 12*12mm that its overall dimension of touch-switch of a kind of 10*10 or 12*12 is wherein arranged; Press shift knob during use gently and just can make switch connection; Switch breaks off when unclamping hand, and its internal structure realizes break-make by the metal clips stress deformation.The classification of waterproof of dustproof and 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.The terminal and the base of existing dustproof and waterproof touch-switch are injected into one, and metal terminal is a laminated structure, and metal terminal is provided with tip side, and tip side is in the die cavity of base.Because metal terminal is different with the thermal coefficient of expansion of plastic feet; Be prone to very little gap between the inward flange of metal terminal and the plastic feet; Water can penetrate in the plastic feet from this gap location lentamente, and the metal terminal linear pattern extend in the plastic feet, climbs water apart from weak point; Waterproof effect is poor, is difficult to reach the anti-water quality standard of the above grade of IP6.
Summary of the invention
For the metal terminal that overcomes existing 10*10 or 12*12 dustproof and waterproof touch-switch is climbed water apart from weak point; The deficiency of waterproof effect difference; The utility model provides a kind of dustproof and waterproof touch-switch; This dustproof and waterproof touch-switch has increased the both sides of metal terminal in plastic feet and has climbed the water distance, has improved water resistance, good water-proof effect.
The technical scheme of the utility model is: this dustproof and waterproof touch-switch comprises plastic feet and metal terminal; Metal terminal and plastic feet are injected into one; Metal terminal is divided into first brace, side tip side, second brace and central contact end, and first brace and side tip side are one, and second brace and central contact end are one; Side tip side and central contact end are positioned at the plastic feet die cavity; All stretch out outside the plastic feet at the two ends of first brace and second brace, is provided with bending section between the two ends of first brace and the side tip side, also is provided with bending section between the two ends of second brace and the central contact end; Described bending section is in the entity of plastic feet, and the side tip side stretches out along the centre of first brace and to the middle part of central contact end both sides bending extension to plastic feet die cavity.
Described bending section is outside or aduncate circular arc.
The utlity model has following beneficial effect: owing to take such scheme; Be provided with bending section 23 in first brace 21 and second brace 23 and the physical location that plastic feet 1 combines on the metal terminal 2; Increase the both sides of metal terminal 2 in plastic feet 1 and climbed the water distance; Improved water resistance, good water-proof effect.
Description of drawings
Accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 are the structural representations of the utility model.
Accompanying drawing 5 is structural representations of the metal terminal 2 of the utility model.
Accompanying drawing 6 is structural representations of the metal terminal 2 of prior art.
1-plastic feet among the figure, 2-metal terminal, 21-first brace, 22-side tip side, 23-second brace, 24-central contact end, 3-bending section.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By Fig. 1, Fig. 2, shown in Figure 3, the utility model is the improvement of 10*10 dustproof and waterproof touch-switch, also is applicable to simultaneously the dustproof and waterproof touch-switch of 12*12 specification, is divided into two kinds of installation forms, be respectively vertical (Fig. 1, Fig. 4) with horizontal (Fig. 2, Fig. 3); (Fig. 1, Fig. 2 is Fig. 4) with short pin configuration (Fig. 3) to be divided into long pin configuration by pin configuration.By shown in Figure 5; This dustproof and waterproof touch-switch comprises plastic feet 1 and metal terminal 2; Metal terminal 2 is injected into one with plastic feet 1; It is one with side tip side 22 that metal terminal 2 is divided into first brace 21, side tip side 22, second brace 23 and central contact end 24, the first braces 21, and second brace 23 and central contact end 24 are one; Side tip side 21 is positioned at plastic feet 1 die cavity with central contact end 22; All stretch out outside the plastic feet 1 at the two ends of first brace 21 and second brace 23, is provided with between the two ends of first brace 21 and the side tip side 22 between two ends and the central contact end 24 of bending section 3, the second braces 23 and also is provided with bending section 3; Described bending section 23 is in the entity of plastic feet 1, and side tip side 21 stretches out along the centre of first brace 21 and to the middle part of central contact end 24 both sides bending extension to plastic feets 1 die cavity.Owing to adopt such scheme; Compare with prior art (shown in Figure 6); Be provided with bending section 23 in first brace 21 and second brace 23 and the physical location that plastic feet 1 combines on the metal terminal 2; Increase the both sides of metal terminal 2 in plastic feet 1 and climbed the water distance, improved water resistance, good water-proof effect.
By shown in Figure 5, described bending section 3 is outside or aduncate circular arc.Present embodiment is a preferred version, does not get rid of bending section 3 and adopts other curved shape, and adopting circular arc mainly is to be convenient to processing.
