Abstract

The utility model discloses a toggle switch which comprises a housing and a shifting rod. A switch base body is arranged inside the housing and is provided with a plurality of pole pieces; the pole piece is provided with a swinging chip; one end of the shifting rod is exposed out of the housing while the other end extends into the housing and is provided with a central rod; the tail end of the central rod is provided with a sleeve head; the end of the shifting rod which extends into the housing is provided with a slot in the axial direction of the shifting rod; and a reducing part with an aperture smaller than that of the slot is arranged above the slot so that the shifting rod has a wall with a certain thickness. Thereby, the wall thickness is increased and the strength of the shifting rod is improved without increasing the diameter of the shifting rod, which prevents static electricity gathers on the shifting rod in dry weather.

Description

Head-shaking switch

Technical field

The utility model relates to a kind of head-shaking switch, is specifically related to a kind of head-shaking switch that can effectively avoid group rod generation static and group excellent hardness to satisfy user demand.

Background technology

Head-shaking switch is a device commonly used in the electronic product, can as required it be toggled it to suitable position, and then realizes circuit switched or unlatching, closes function such as signal.Existing head-shaking switch structure comprises square casing 60 as shown in Figure 3, is provided with switch base body 70 in the housing 60, and this switch base body 70 is provided with some pole pieces 71, is provided with the swing sheet 72 as the figure of three of laying across on pole piece 71; Be provided with group rod 80 in housing 60 central authorities, dial rod 80 1 ends and stretch out the outer end, the other end is equipped with center rod 90, and contacts with swing sheet 72 by center rod 90; Dial in the rod 80 and be provided with microscler jack 81, just be installed with a spring 82 in the jack 81, these spring 82 1 ends align the jack openings place; Center rod 90 1 ends stretch in the jack 81, and are butted on the end of spring 82, and it is pullover 91 that another degree of center rod 90 is provided with, and this is pullover 91 for the circle that expands rolls cone, and pullover 91 can pushing more glidingly above swing sheet 72.As shown in Figure 3, will dial rod 80 and promote towards left, center rod 90 bottoms are just moved towards the right side, and swing sheet 72 right sides are pressed down and contact with the pole piece 71 on right side, thus the unlatching or the closing function of realization switch.

But, in existing head-shaking switch structure, dial rod 80 and be made of metal, in use, often have above static stays, dry more local this phenomenon is obvious more.When stretching out one's hand touch switch, static takes place suddenly, the people is got a fright, make troubles for people's use.Though dialling rod, some adopt the insulation material to make, this construction of switch complexity, and it is relatively poor to dial excellent intensity, in use often breaks down.

The utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of can some avoid generation of static electricity and head-shaking switch simple in structure, that serviceability is good.

Technical scheme: for solving the problems of the technologies described above, head-shaking switch of the present utility model comprises housing and group rod, is provided with the switch base body in the housing, and the switch base body is provided with some pole pieces, and pole piece is provided with the swing sheet; Dial an excellent end and expose housing, group excellent other end stretches in the housing and is provided with center rod, and the center rod end is provided with pullover; The described group of group rod that rod is made for insulation material (for example hard plastic cement) makes it can prevent from dialling static electricity gathered on the rod under the dry weather condition; Be axially arranged with the less slot of diameter along what dial rod dialling a end that rod stretches into housing, slot top is provided with the aperture less than slot and make and dial rod and have the constriction of certain wall thickness, like this, do not increasing under the situation of dialling excellent diameter, making the wall thickness increase and make and dial excellent intensity increase; Described center rod is thinner shaft-like, and center rod places in the slot, is with spring on the center rod, spring be located at the constriction lower port and pullover between, it is flexible to make center rod do fine motion in dialling rod.Described pole piece extension downwards is provided with the utmost point pin that is connected with other electrical equipment; On pole piece, be provided with swing sheet as the figure of three of laying across.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

As illustrated in fig. 1 and 2, head-shaking switch of the present utility model comprises housing 10 and group rod 30, is provided with switch base body 20 in the housing 10, and switch base body 20 is provided with some pole pieces 21, and pole piece 21 extension downwards is provided with the utmost point pin 23 that is connected with other electrical equipment; On pole piece 21, be provided with swing sheet 22 as the figure of three of laying across; Dial rod 30 and made by insulation material (as hard plastic cement), dial rod 30 1 ends and expose housing 10, dial excellent 30 other ends and stretch in the housing 10 and be provided with center rod 40, center rod 40 ends are provided with pullover 41; Be axially arranged with the less slot of diameter 31 along what dial rod 30 dialling a end that rod 30 stretches into housing 10, slot 31 tops are provided with the aperture less than slot 31 and make and dial rod 30 and have the constriction 32 of certain wall thickness d, like this, do not increasing under the situation of dialling excellent 30 diameters, making the wall thickness increase and make and dial excellent 30 intensity increase.

Center rod 40 be thinner shaft-like with respect to the slot 31 of dialling rod 30, and center rod 40 1 ends are arranged with spring housing 50, and the other end is covered with to expand justifies the taper pullover 41 that rolls; An end that center rod 40 is with spring 50 is inserted in the slot 31, and spring 50 1 ends are butted on the lower port of the constriction 32 of slot 31, and the other end then is butted on pullover 41 inner edges, and it is flexible to make center rod 40 do fine motion in dialling rod 30.As shown in Figure 2, will dial rod 30 and promote to the left, pullover 41 of center rod 40 ends are promoted to opposite side (right-hand), then can with swing sheet 22 this side of a side direction press down with pole piece 21 and touch and starting switch mutually, vice versa.

The utility model is selected for use insulation material (as hard plastic cement) to make and is dialled rod, can prevent to produce static; In order to make the insulation material reach certain intensity, do not adopt the mode that increases external diameter, but vertically to establish the less slot of a diameter at it, and form constriction and have more suitable wall thickness in that this slot is terminal so that dial rod, make it still have certain intensity because of wall thickness increases, but because of external diameter is constant, just can continue to use multiple part commonly used, cost was constant when quality was improved.

The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
