Description
Technical field
The present invention relates to a kind of LED illumination lamp, especially belong to a kind of small-power rotary clamp type LED illumination lamp being applicable to being arranged on high-voltage switch cabinet inner roof wall.
Background technology
Before the present invention makes, high-voltage switch cabinet intraoral illumination adopts incandescent lamp usually, and therefore, there are the following problems: cost energy consumption is high, for reaching certain brightness, guarantees completing smoothly of job task, usually needs to use the incandescent lamp of more than 40W just can meet the demands; Service life is short, and incandescent lamp lies prostrate in voltage range at 200-230 and runs, and service life only has more than 1000 hour usually; Needing to set up protector, for eliminating safe hidden trouble, usually needing to set up safty shield in incandescent lamp periphery.Because LED illumination lamp has, brightness is high, energy consumption is low, long service life, and does not need to set up the plurality of advantages such as safty shield, substitutes incandescent lamp become development trend as high-voltage switch cabinet intraoral illumination by LED.But, because prior art exists following problems, cause LED to substitute incandescent lamp to fail to apply as high-voltage switch cabinet intraoral illumination always, 1, by space constraint in cabinet, the draw bail of existing rotary joint style lamp holder and lamp socket can not meet installation requirement, exists and affects the problem that in cabinet, original instrument layout or cabinet door are opened; 2, LED drive unit has polar requirement, and the cassette syndeton of original lamp holder and lamp socket can not realize the available protecting to LED drive unit.
Summary of the invention
For solving the problems of the technologies described above, the present invention aims to provide a kind of high-tension switch cabinet rotary clamp type LED illumination lamp, this light fixture have rational in infrastructure, easy accessibility, polarity orientation are reliable, and the advantage that in cabinet, original instrument layout or cabinet door are opened after installing, can not be affected, be especially applicable to using in high-voltage switch cabinet.
For solving the problems of the technologies described above, present invention employs following technical proposals, the structure of this high-tension switch cabinet rotary clamp type LED illumination lamp, comprises lamp holder and lamp socket, and the connector of this lamp holder is provided with the first movable contact spring and the second movable contact spring; Match with the profile of described connector, described lamp socket has a receiving opening, the first static contact and the second static contact is arranged with at the outer of this receiving opening, it is characterized in that: on the outer wall of described connector, radial direction is provided with the not identical convex region of two areas of section, match therewith, the hole wall of described lamp socket receiving opening is provided with corresponding recessed district; Be arranged with left-handed stop block and dextrorotation stop block at the outer of described lamp socket receiving opening, described left-handed stop block and dextrorotation stop block limit direction of rotation and the distance of described lamp holder respectively.
During concrete enforcement, the shape of described connector is cylindricality, and described first movable contact spring and the second movable contact spring radial direction are arranged on the both sides of connector.
During concrete enforcement, described first static contact and the second static contact are fixedly installed on the both sides of described receiving opening, and both spacing are less than the maximum outside diameter of described connector.
Beneficial effect: compared with prior art, lamp holder of the present invention and lamp socket adopt rotary clamp type to be connected, not only rational in infrastructure, easy accessibility, particularly effectively can reduce the height after both connections, therefore, be arranged on after in high-tension switch cabinet, the equipment such as the device in cabinet, instrument that were originally arranged on without the need to layout again, thus are laid a good foundation to replacement.Moreover, utilize the recessed plot structure on the convex region on connector and receiving opening, make lamp holder enter lamp socket according to the polarity of setting, and the breaking-up of LED drive unit need not be worried.
Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail.
Detailed description of the invention
See Fig. 1.This high-tension switch cabinet rotary clamp type LED illumination lamp is made up of lamp socket 1 and lamp holder 2 two parts, and the front portion of lamp holder 2 is light source, and this light source is made up of many LED 22.The periphery of LED 22 has a translucent cover 21.The rear portion of lamp holder 2 is connector 23.Lamp socket 1 has the receiving opening 11 that a profile and connector 23 match, after connector 23 screws in receiving opening 11, lamp holder 2 and lamp socket 1 just can be made to realize electrical connection, make LED 22 shinny.For convenience of using, lamp socket 1 is provided with a power switch 12, to control lighting lamp power.
See Fig. 2, and composition graphs 3.Key innovations of the present invention is that lamp holder 2 is with in the draw bail of lamp socket 1.The connector 23 of lamp holder 2 is positioned at the rear portion of lamp holder 2 in cylindricality.On the cylindrical outer wall of connector 23, radial direction is provided with the not identical convex region of two areas of section, and wherein, radial convex tendon 1 and convex tendon 2 233 form large convex region, and the first movable contact spring 232 is between convex tendon 1 and convex tendon 2 233, and radial protrusion outside.Opposing with large convex region, little convex region is then formed by two radial convex tendons 3 236, and the second movable contact spring 235 is therebetween, and radially protrudes outside.
See Fig. 2, and composition graphs 4.Match with the structure of connector 23, the hole wall 111 of lamp socket 1 receiving opening 11 is provided with corresponding recessed district, that is: great Ao district 119 and little Ao district 120.This structure ensure that lamp holder 2 enters the uniqueness of lamp socket 1, realizes the object entered by setting polarity, and without the need to worrying the breaking-up of LED drive unit.Be arranged with left-handed stop block 113 and dextrorotation stop block 118 at the outer of receiving opening 11, described left-handed stop block 113 and dextrorotation stop block 118 are respectively used to the direction of rotation and the distance that limit lamp holder 2.Described first static contact 112 and the second static contact 116 are fixedly installed on the both sides of described receiving opening 11, are fixed by corresponding locating dowel 117.The spacing of the first static contact 112 and the second static contact 116 is less than the maximum outside diameter of described connector 23, and the maximum outside diameter essence of connector 23 described here refers to the first movable contact spring 232 and the second movable contact spring 235 torque.Screw 114, for the cover plate of fixed lamp-socket 1, can realize the fixing of lamp socket 1 through locating hole 115.
For further understanding, the connection process of illustratively lamp holder 2 and lamp socket 1 more below:
See Fig. 2, and composition graphs 5.Convex tendon 1 and convex tendon 2 233 are formed one end, large convex region and aims at great Ao district 119, connector 23 is pushed in receiving opening 11.
See Fig. 2, and composition graphs 6.By clockwise for connector 23 90 degree, the first static contact 112 of the first movable contact spring 232 and the second movable contact spring 235 and both sides and the second static contact 116 are held out against, realizes electrical connection, and utilize the inner face of four convex tendons to be engaging on the hole wall 111 of receiving opening 11 by lamp holder 2.
During installation, this illuminating lamp both can be arranged on the roof of high-tension switch cabinet, also can be arranged on cabinet door.
Above-described embodiment is only and technology contents of the present invention is described, any simple deformation design made according to the present embodiment, all should include in protection scope of the present invention.
