Abstract
A light touch switch comprises an insulated main body provided with a holding space, a fixed terminal group held inside the holding space, a movable terminal arranged above the fixed terminal group, a press body butted with the movable terminal, and a cover body covering the insulated main body, wherein, the press body comprises a press part and a drive part arranged below the press part; a through hole to be penetrated by the press body and a tubular body vertically extending downwards from the edge below the through hole are arranged on the cover body, wherein, a groove corresponding to the tubular body is formed between the press body and the drive part, thus dust and foreign material can deposit in the groove, and are prevented from depositing into the contact area of the movable terminal and the fixed terminal.
Description
[technical field]
The utility model relates to a kind of touch-switch, refers in particular to a kind of touch-switch that is applied on the electronic product equipment.
[background technology]
Touch-switch generally includes the insulating body that is provided with receiving space, is contained in the fixed terminal group in the insulating body, the movable terminal that is installed on fixed terminal group top, the pressing body of butt movable terminal, and is placed on the lid on the insulating body.Wherein, lid central authorities are provided with through hole, because through hole cooperates with pressing body and has the gap, dust and foreign matter just can fall into from the gap easily, and along whereabouts, pressing body surface, and then in the contact zone of movable terminal and fixed terminal group deposition, thereby have influence on the conducting of touch-switch excellent electrical property.
For addressing the above problem, the common way of industry is: baffle plate is set or at the dustproof film of movable terminal surface coverage above lid.Yet, baffle plate is set on lid, can makes the touch-switch volume increase, and at the dustproof film of movable terminal surface coverage, still there are dust and foreign matter can fall into the contact zone of fixed terminal and movable terminal, influence the conducting of touch-switch from the gap of movable terminal and insulating body.
In view of above drawback, be necessary to provide a kind of improved touch-switch in fact, to overcome the defective of above-mentioned touch-switch.
[utility model content]
The purpose of this utility model is to provide a kind of dustproof respond well touch-switch.
The utility model touch-switch comprises the insulating body that is provided with receiving space, is contained in the fixed terminal group in the insulating body, the movable terminal that is installed on the fixed terminal top, the pressing body of butt movable terminal, and be placed on lid on the insulating body, wherein, pressing body comprises the press section and places the drive division of below, press section, have on the lid and can reach the tubular body that extends vertically downward by the through hole lower edge, wherein: form and the tubular body corresponding grooves between pressing body and the drive division for the through hole that the pressing body press section is run through.
Compared with prior art, the utility model touch-switch pressing body is provided with groove, lid is provided with tubular body, the structure that groove matches with tubular body, make the dust and the foreign matter that enter from pressing body and lid fit clearance deposit, effectively improved the dustproof effect of touch-switch and simple in structure at groove.

Fig. 3 is the three-dimensional combination figure of the utility model touch-switch.
Fig. 4 is the profile of the three-dimensional combination figure of the utility model touch-switch along Fig. 3 IV-IV face.
[embodiment]
Please refer to Fig. 1 to shown in Figure 4, the utility model touch-switch 100 comprises the insulating body 1 that is provided with receiving space 10, be contained in fixed terminal group 5 in the insulating body 1, be installed on the movable terminal 4 of fixed terminal group 5 tops, the pressing body 3 of butt movable terminal 4, and is placed on the insulating body 1 lid 2 that movable terminal 4 and pressing body 3 is fixing.
Pressing body 3 comprises columniform press section 30 and places below, press section drive division 31 in the form of annular discs.Wherein, tubular body 21 corresponding grooves 300 of formation and lid 2 between press section 30 and the drive division 31, like this, when the gap between lid 2 and pressing body 3 falls when dust and foreign matter, can directly fall into above-mentioned groove 300, and can not amass in movable terminal 4 and fixed terminal group 5 places.
Fixed terminal group 5 is divided into movable contact terminal 51 and static touching terminal 52.Movable contact terminal 51 and movable terminal 4 stressed the backs contact portion during strain downwards are movable contact district 510.Static touching terminal 52 is an overlap 520 with the part of movable terminal 4 overlapping edges.
Please in conjunction with shown in Figure 3, during assembling, movable contact terminal 51 and static touching terminal 52 are injected and molded in insulating body 1 bottom, earlier movable terminal 4 is placed in the receiving space 10 of insulating body 1, at this moment, the overlap 520 of static touching terminal 52 and the EDGE CONTACT of movable terminal 4.Then, pressing body 3 is installed in the receiving space 10 of insulating body 1, at this moment, the drive division 31 butt movable terminals 4 of pressing body 3.At last lid 2 is placed on the insulating body 1, reference column 12 on the location hole 22 of lid 2 and insulating body 1 upper surface 11 is fixing mutually, the through hole 20 of lid 2 central authorities matches with the press section 30 of pressing body 3, thereby pressing body 3 and movable terminal 4 are fixed in the receiving space 10 of insulating body 1.Connector such as Fig. 3 that assembling finishes.
In the present embodiment, the through hole 20 of lid 2 central authorities is extended with tubular body 21 downwards, pressing body 3 is provided with tubular body 21 corresponding grooves 300 with lid 2, and dust and foreign matter will deposit in groove 300 like this, stops the deposition to the contact zone of movable terminal 4 and fixed terminal group 5.
The above only is a kind of execution mode of the present utility model, it or not whole or unique execution mode, the variation of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
