Abstract

The utility model relates to a button with a lamp, comprising a head part of a button, a supporting seat, a lamp holder and a contact module, wherein the head part of the button is mounted on the supporting seat. In order to solve the problems of assembling the contact module in large capacity, the utility model is added with an action plate and a bracket fixed with the supporting seat, wherein the action plate is supported by a reset spring on the bracket, and is contacted with a lower end of the head part of the button. The contact module and the lamp holder are mounted on the bracket. The size of the action plate is decided by that, when the head part of the button of the action plate is moving, the action plate can be contacted with a pushing seat of the contact module.

Description

The band button

Technical field

The utility model relates to a kind of band button switch with linear operating.

Background technology

Traditional band button mainly is made up of button head assembly, supporting base, lamp socket, contact or contact modules, wherein lamp socket is fixed on the supporting base, the direct push contact module of the thrust piece of button head push away seat, its rated current is less, be mainly used in Machine Tool Electric Appliance, not too be fit to the bigger occasion of Control current, as the automatic control of traffic and transport field.Chinese patent CN2807436 discloses a kind of band button, comprise button head, supporting base, lamp socket and contact modules, wherein lamp socket and contact modules are fixed on the supporting base, the lower end of button head and contact modules to push away seat relative, when pressing the button, the lower end of button head pushes the seat that pushes away of contact modules, makes contacting or disconnection in the contact modules.This band button adopts button head directly to contact the fit of contact modules, but the diameter of button head is limited, the button middle body will be installed luminous component in addition, therefore the bulk (particularly thickness) of contact modules can not be too big, this just causes being difficult to equipped big capacity, high performance contact modules, as the S8XX series quick-action switch of the applicant's development.

Summary of the invention

Problem to be solved in the utility model is: a kind of band button that adapts to big capacity contact modules is provided.

The solution that addresses the above problem is: the band button that is provided comprises button head, supporting base, lamp socket and contact modules, button head is installed on the supporting base, special feature of the present utility model is to be provided with an action plate and a support that is connected with supporting base, this action plate is supported by the back-moving spring on the support, and with end in contact under the button head, contact modules and lamp socket are installed on the aforesaid support, the size of said action plate is decision like this: when action plate was passed by button head, action plate can touch with the seated connection that pushes away of contact modules.

The utility model therefore enlarged the installing space of contact modules, and the action plate of setting up has been equivalent to extend the pushing contact range of button head, makes the equipped big capacity contact modules of band button become possibility owing to set up a support.

For the ease of contact modules or lamp socket are installed, the both sides of above-mentioned support can be provided with wing plate, can adopt clasp type to be connected between contact modules and the support wing plate or are threaded.When employing was threaded, the wing plate of support both sides was provided with the installing hole of contact modules.

Compared with prior art, the utility model makes the easier for installation, flexible, reliable of contact modules owing to set up a support and action plate, not only can be equipped with the big capacity contact modules of different model, also can be equipped with other common contact modules.Support of the present utility model in addition and action plate can adopt plate stamping to form, and simple in structure, compact.

The utility model is specially adapted to the automatic control of traffic and transport field, also can be used for the automatic control in other field.

Embodiment

Below in conjunction with accompanying drawing content of the present utility model is described in detail.

As shown in Figure 1 and Figure 2: button of the present utility model mainly is made up of button head 1, supporting seat 2, lamp socket 3, two contact modules 4, support 5 and action plates 6.Support can be the left and right two parts that separate, and also can adopt integrative-structure, and this example adopts integrative-structure, that is: support 5 is made up of top board 51, two side plates 52 and wing plate 53, and top board central authorities have through hole 54, and action plate 6 is positioned at rack plate 51 belows.Pressing button head 1, its lower end pass through the through hole 54 of support 5, contact with action plate 6, and pushing action plate 6 move.Rack plate 51 is riveted together with the lower surface of supporting seat 2, has installing hole 55 on the support wing plate 53, and lamp socket 3 and contact modules 4 are installed on the support wing plate 53 by screw, and action plate 6 is supported by the back-moving spring on the support 7.The central authorities of action plate 6 have the through hole 61 that the luminous component 31 that can allow on the lamp socket passes through.The pushing button head 1, action plate 6 moves down, so depress contact modules 4 push away the seat 41, make contacting or disconnection; After loosing one's grip, action plate 6 is got back to the home position under the effect of back-moving spring 7.

As shown in Figure 3, Figure 4: in order to make compact conformation, guarantee that back-moving spring 7 stressed all even action plates 6 move steadily, be provided with sliding tray 56 on rack side plate 52, back-moving spring 7 is enclosed within on the lead 57 in the sliding tray 56; The dual-side of action plate 6 has travelling carriage 62, and travelling carriage 62 places the sliding tray 56 of rack side plate, and travelling carriage 62 is moved along sliding tray 56, and travelling carriage 62 also has the effect of spring base concurrently.Travelling carriage 62 on sliding tray 56 on the above-mentioned rack side plate, lead 57 and the action plate all adopts the Sheet Metal Forming Technology moulding of sheet material.Test shows, this button reliable operation, steady, and back-moving spring 7 still can maintain a good state after 1,000,000 operations, has improved the working life of button greatly.

Fig. 5 has provided the stereogram of the utility model the foregoing description, contact modules wherein adopts S8XX series quick-action switch, the rated capacity of its contact has 0.5A, 1A, 10A plurality of specifications, can freely select according to user's requirement, and 24V is arranged, two kinds of specifications of 110V (AC/DC) are available, are specially adapted to the electrical control of traffic transport industry.
