CN202332656U - Waterproof touch switch for automatic component insertion of braiding - Google Patents

Abstract

The utility model discloses a waterproof touch switch for the automatic component insertion of braiding, and mainly aims to solve the problems of poor waterproof effects caused by short water creeping distances between a first pin and a side contact end and between a second pin and a center contact end of the conventional waterproof touch switch. The waterproof touch switch is characterized in that: a strip-type opening (6) is formed between the first pin (2) and an adjacent side contact end (3); and the center contact end (5) forms an acute angle (a) with the second pin (4), and is linearly extended to the center of a base (1). According to the waterproof touch switch for the automatic component insertion of the braiding, the water creeping distances between the first pin and the side contact end and between the second pin and the center contact end in the plastic base are prolonged, so that waterproofness is improved, and a good waterproof effect is achieved.

Description

Braid automatic insertion waterproof touch-switch

Technical field

The utility model relates to a kind of electronic switch, is specifically related to a kind of braid automatic insertion 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 metal terminal, base, shell fragment, gland, gummed paper, silica gel and button, and metal terminal and base are injected into one, and the metal terminal top is provided with shell fragment, gland, gummed paper, silica gel and button successively.Metal terminal wherein comprises contact jaw and pin; As shown in Figure 1, metal terminal is divided into the first metal end and second metal terminal, and the first metal end is made up of first pin and two side contact jaws; Second metal terminal is made up of second pin and center contact jaw; All bending back in the center line right angle of contact jaw passes in the middle of the base bottom along the center for first pin and second pin, arc transition between the side contact jaw of first pin and vicinity, and the center contact jaw and second pin are the right angle; The center contact jaw stretches out the back and bends to center; Metal terminal is different with the thermal coefficient of expansion of plastic feet, is prone to very little gap between metal terminal and the plastic feet, and water can penetrate in the plastic feet from this gap location lentamente; Climb water apart from weak point between first pin and the side contact jaw and between second pin and the center contact jaw; Waterproof effect is poor, is difficult to reach the anti-water quality standard of the above grade of IP6 and maybe can not reaches switch was placed in the dark normal-temperature water of 10cm after 24 hours, takes out to put on the skin and does surperficial water stain measurement insulation resistance greater than 100 megaohms.

The utility model content

In order to climb water apart from weak point between first pin that overcomes existing waterproof touch-switch and the side contact jaw and between second pin and the center contact jaw; The deficiency of waterproof effect difference; The utility model provides a kind of braid automatic insertion waterproof touch-switch; This braid automatic insertion waterproof touch-switch has increased between first pin and the side contact jaw and in plastic feet, has climbed the water distance between second pin and the center contact jaw, has improved water resistance, good water-proof effect.

The technical scheme of the utility model is: this automatic insertion waterproof touch-switch comprises base, first pin, two side contact jaws, second pin and center contact jaws; First pin and two side contact jaws are structure as a whole; Second pin and center contact jaw are structure as a whole; All bending back in the center line right angle of contact jaw passes from base along the center for first pin and second pin; Being provided with the bar shaped gap between the side contact jaw of first pin and vicinity, is the center that acute angle and center contact jaw straight line extend into base between the center contact jaw and second pin.

The utlity model has following beneficial effect: owing to take such scheme; Increased between first pin and the side contact jaw and in plastic feet, climbed the water distance between second pin and the center contact jaw; Improved water resistance; Good water-proof effect can reach switch was placed in the dark normal-temperature water of 10cm 24 hours or after the longer time, took out to put on the skin and do surperficial water stain measurement insulation resistance greater than 100 megaohms.

Accompanying drawing 3 is perspective view that the utility model metal terminal and plastics combine.

1-base among the figure, 2-first pin, 3-side contact jaw, 4-second pin, 5-center contact jaw, 6-gap, a-acute angle.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Combine shown in Figure 3 by Fig. 2; This automatic insertion waterproof touch-switch comprises base 1, first pin 2, two side contact jaws 3, second pin 4 and center contact jaws 5; First pin 2 and two side contact jaws 3 are structure as a whole; Second pin 4 is structure as a whole with center contact jaw 5; All bending back in the center line right angle of contact jaw 5 passes in the middle of base 1 bottom along the center for first pin 2 and second pin 4, is provided with bar shaped gap 6 between the side contact jaw 3 of first pin 2 and vicinity, is the center that acute angle a and center contact jaw 5 straight lines extend into base 1 between the center contact jaw 5 and second pin 4.Arrow points is the signal that water immerses base 1 among the figure; Such scheme has increased between first pin 2 and the side contact jaw 3 and in plastic feet 1, has climbed the water distance between second pin 4 and the center contact jaw 5; Improved water resistance; Good water-proof effect can reach switch was placed in the dark normal-temperature water of 10cm 24 hours or after the longer time, took out to put on the skin and do surperficial water stain measurement insulation resistance greater than 100 megaohms.

Claims (1)

1. braid automatic insertion waterproof touch-switch; Comprise base (1), first pin (2), two side contact jaws (3), second pin (4) and center contact jaw (5); First pin (2) is structure as a whole with two side contact jaws (3); Second pin (4) is structure as a whole with center contact jaw (5); All bending back in the center line right angle of contact jaw (5) passes from base (1) along the center for first pin (2) and second pin (4); It is characterized in that: being provided with bar shaped gap (6) between the side contact jaw (3) of first pin (2) and vicinity, is the center that acute angle (a) and center contact jaw (5) straight line extend into base (1) between center contact jaw (5) and second pin (4).
