Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 and Fig. 2 is the overall schematic Sum decomposition schematic diagram of breaker in middle of the present invention respectively.As depicted in figs. 1 and 2, the switch 100 of the present invention button 103 that comprises knob 101, be set in the fixed cover 102 outside knob 101 and be arranged in knob 101.Composition graphs 3, whole switch 100 is fixed on the housing 200 of electronic installation by fixed cover 102.
Knob 101 comprises linkage part 106 and is connected to the operating portion 105 of first end of linkage part 106.Operating portion 105 is in column, and periphery is provided with annular knurl, and applicable hand rotates; But operating portion 105 also can adopt other suitable shapes, as hemispherical, round table-like etc.At operating portion 105 center, be provided with through hole 107.
Linkage part 106 is in elongated tubular, and its inner space is communicated with the through hole 107 of operating portion 105.In linkage part 106, be provided with and extend vertically and run through the sliding tray 108 of perisporium, this sliding tray 108 extends near operating portion 105 from the second end of linkage part 106.On the outer peripheral face of linkage part 106, be also provided with the back-up ring location notch 109 of circumference, this back-up ring location notch 109 does not run through perisporium.In linkage part 106, be provided with internal thread segment 110, this internal thread segment 110 is positioned near the second end.
In one embodiment of the invention, operating portion 105 is made up of plastic cement, and linkage part 106 is made of metal, and is embedded in operating portion 105.
Fixed cover 102 comprises guide part 111 and is connected to the locating flange 112 of first end of guide part 111.This guide part 111, in tubular, is provided with axial groove 113 and the circumferential slot 114 from axial groove 113 extension.This axial groove 113 extends near locating flange 112 from the second end of guide part 111.Fixed cover 102 is arranged on the housing of electronic installation by locating flange 112.
Switch 100 also comprises back-up ring 115, and this back-up ring 115 is set in linkage part 106, and coordinates with back-up ring 115 location notch 109 and locate.
Fixed cover 102 is set in the linkage part 106 of knob 101, and blocked by back-up ring 115, thus between the operating portion 105 and back-up ring 115 of knob 101, after on the housing 200 being installed to electronic equipment, fixed cover 102 keeps fixing relative to knob 101 in the axial direction.When on the housing 200 that switch 100 is installed to electronic installation, the operating portion 105 of knob 101 is positioned at outside housing 200, and linkage part 106 extends in housing 200.Sliding tray 108 on knob 101 is aimed at the axial groove 113 on fixed cover 102.The locating flange 112 of fixed cover 102 is fixed on the inwall of housing 200 of electronic installation, thus switch 100 is fixed.
Button 103 comprises interconnective press section 116 and location division 117.Wherein the peripheral dimension of press section 116 is less than location division 117, and the diameter of through hole 107 on operating portion 105 is between press section 116 and the peripheral dimension of location division 117.Location division 117 is provided with the radial pin 118 extended.
Button 103 is arranged in linkage part 106, and its press section 116 extends through the through hole 107 on operating portion 105, and the pin 118 on location division 117 extends to from the sliding tray 108 linkage part 106 in the axial groove 113 on fixed cover 102.
In fixed cover 102, be also provided with flexible member 119, this flexible member 119 pushes against on the location division 117 of button 103, applies towards the pushing and pressing elastic force in operating portion 105 direction button 103.This flexible member 119 is such as springs.
Switch 100 also comprises compressing tablet 104.The touching portion 120 that this compressing tablet 104 comprises reference column 122 and extends from reference column 122 radial direction.Wherein reference column 122 is fixedly installed in linkage part 106, and touching portion 120 extends through the sliding tray 108 in linkage part 106.In the illustrated embodiment in which, the quantity in touching portion 120 is two, is arranged on the both sides of reference column 122 symmetrically.The quantity of sliding tray 108 is correspondingly also two.But the quantity in touching portion 120 also can be one.
In an embodiment of the present invention, switch 100 also comprises plug 121.This plug 121 is roughly column, with external screw thread.This external screw thread coordinates with the internal thread segment 110 in linkage part 106, thus plug 121 is fixed in linkage part 106.Because flexible member 119 is arranged between button 103 and compressing tablet 104, one end pushing and pressing are on button 103, and other end pushing and pressing, on compressing tablet 104, make compressing tablet 104 be resisted against on plug 121 and locate.
Composition graphs 4 and Fig. 5, switch 100 can be used for pressing first, second contact pressing piece 202,203 in the housing 200 of electronic equipment, thus connects the first circuit and second circuit respectively.Wherein the first contact pressing piece 202 is positioned at primary importance, and the second contact pressing piece 203 is positioned at the second place.When not applying external force to switch 100, the pin 118 on button 103 is arranged in sliding tray 108 and axial groove 113 position near the operating portion 105 of knob 101, and compressing tablet 104 presses the first contact pressing piece 202.When the first circuit, connection second circuit will be disconnected, first press the button the press section 116 of 103, make pin 118 slide into the position of circumferential slot 114 along the axial groove 113 on fixed cover 102, turning knob 101 afterwards, make pin 118 enter circumferential slot 114.Compressing tablet 104 turns to the second place thereupon and presses the second contact pressing piece 203, connects second circuit.
Application of the present invention is not limited thereto, and when primary importance and the second place, compressing tablet 104 also can be respectively used to disconnect or connect same circuit.
Due to when console switch 100, need first to press the button 103, afterwards turning knob 101 again, compressing tablet 104 just can be driven to be switched on or switched off circuit, effectively can prevent misoperation.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
