Description
Technical field
The utility model relates to contactor, exactly is mounted in the push-button switch on the various switch panels.
Background technology
Push-button switch is a kind of control element commonly used, has been widely used in industries such as industrial automation, medicine equipment, electric power, machinery, communication, transportation, metallurgy, chemical industry.
Please refer to Fig. 1, it shown in the figure cutaway view that a kind of common push-button switch is installed on switch panel in the prior art, mainly by switch body 20 ', button assembly 30 ', housing 10 ' and locking nut 50 ' assemble, switch body 20 ' form wherein by switch module and luminescence component, luminescence component comprises LED lamp and the leg of drawing from the LED lamp downwards, button assembly 30 ' by button cap, scattering sheet, the astigmatism cover, sealing shroud, connector is formed, button Face is the light transmission part, can form whole astigmatic effect, the connector bipod of the button assembly that combines inserts in the switch body relative opening fixing, sealing shroud 304 ' sealed under elastic reaction switch body jack end face.
Elastic caoutchouc sealing shroud 304 ' the cross section be " U " shape that opening makes progress, its top has the inward flange, the bottom that pack tightly the inside ring-type protrusion of astigmatism cover groove and has the outward flange that protrudes to outer ring-like, the elastic seal cartridge of this structure not only can play sealing and dustproof effect, and its elasticity can also play the effect of push-button reset of allowing.
Above-mentioned switch body 20 ' and the button assembly 30 ' housing of packing into together in, its switch body housing and button assembly housing are integral structure, be used to be supported on switch panel 60 ' on the buckle part be the limited step of transition junction, down be one section external screw thread that is positioned on the switch body housing.
Please refer to Fig. 2, during installation, whole housing by its limited step be supported on switch panel 60 ' on, the switch body housing is arranged in installing hole, its shape, size and installing hole are suitable, locking nut 50 ' it is tightened up fixing through backing plate 70 from the inboard.
As shown in Figure 3, with rectangle, square and circular three kinds of difform push-button switches be installed on switch panel 60 ', the button assembly housing of each push-button switch exposes fully, exceeds switch panel 60 ' certain distance, simultaneously, button cap exceeds button assembly housing certain distance again, button is protruded about switch panel 10mm, cause that the switch head is higher, intensity difference, yielding, easy fracture, and operations area is little, neither attractive in appearance, also being collided with easily is damaged.
Therefore, how to reduce the height of head after push-button switch is installed, make it have higher intensity and bigger operations area, visual effect is very attractive in appearance again simultaneously, is the problem that those skilled in the art need solve.
The utility model content
The purpose of this utility model is to provide a kind of improved push-button switch.This push-button switch can be installed by veneer basically, and the distance that button head can be protruded switch panel reduces to minimum, to evade many drawbacks that high switch head exists.
The utility model adopts following technical scheme:
A kind of push-button switch, comprise housing, be positioned at the switch body of enclosure interior and button assembly with and on locking nut, described housing top is the button assembly housing, the bottom is the switch body housing, the top edge of described button assembly housing has the buckle part.
Preferably, described button assembly is seated in the button assembly enclosure interior fully, and its button Face flushes with button assembly housing upper surface substantially.
Preferably, the buckle part of described button assembly housing top edge is made of the annular flange dish of external peripheral surface.
Preferably, described annular flange dish lower edge is provided with elastic rubber sealing ring.
Preferably, be arranged with the lock sleeve of pushing ahead on the described switch body housing by locking nut.
Preferably, described housing is a split-type structural, wherein the inner circumferential surface of button assembly lower housing portion is provided with annular boss, and the top edge of switch body housing is provided with the ring edge of outside protrusion, and the button assembly housing is connected by the mutual buckle of annular boss and ring edge with the switch body housing.
Preferably, the both sides of described annular boss and ring edge have flat horizontal surface, form anti-rotation structure.
Preferably, be provided with elastic rubber sealing ring at the buckle connecting portion between described button assembly housing and the switch body housing.
Preferably, the sealing shroud outward flange of described button assembly contacts with switch body housing upper surface is flexible.
Preferably, rounded, the square or rectangle of described button assembly, corresponding also rounded, the square or rectangle of button assembly housing.
Push-button switch provided by the utility model is to improve to form on the basis of conventional button switch.The conventional button switch is buckled on the switch panel by the limited step in the middle of the housing, and so, its button assembly housing inevitably can outwards protrude, and the button cap of adding button assembly exceeds the distance of button assembly housing, and the switch head height is inevitable very big.To this, the this patent push-button switch improves on mounting structure, the buckle part of housing is moved to button assembly housing top edge, it no longer is the limited step in the middle of the housing, it during installation the installing hole that the push-button switch housing is arranged in switch panel, whole like this switch case is just imbedded switch panel fully, only there is the buckle part to be fitted in the switch panel outside, the switch head height reduces 4mm～7mm at least, and the reduction of height can improve switch head intensity, makes that it is not yielding, easy fracture not, and very attractive in appearance, also being not easy is collided with is damaged.
In a kind of preferred implementation, described button assembly is seated in the button assembly enclosure interior fully, and its button Face flushes with button assembly housing upper surface substantially.Like this, the switch head of push-button switch just is fully retracted enclosure interior, no longer outwards protrude, thereby the height minus of switch head to minimum degree, can be installed by veneer basically, and the height of its exposed parts depends on the thickness with the buckle part, and this size can be controlled between 2mm～3mm basically, compare with the switch head height about conventional button switch 10mm, significantly reduce, the various drawbacks that can evade high switch head fully and brought.
In another kind of preferred implementation, described housing is a split-type structural, and the mutual buckle of switch body housing of the button assembly housing on its top and bottom is connected, and the back two housing sections is installed in the drop-down tightening of the effect of locking nut and lock sleeve position.Here housing is upper and lower separately, can not only improve interchangeability and versatility between the different push-button switch parts, simultaneously can carry out processing and manufacturing respectively, help reducing technology difficulty and cost, and the connected mode of buckle is very firm and be easy to assembling it.
