Abstract
The utility model relates to an explosionproof lamp, comprising a net, a transparent cover, a light source, a lamp holder, a lamp casing, a connecting box cover, and a connecting plate assembly. The explosionproof lamp is characterized in that the connecting plate assembly is divided into an upper connecting plate assembly and a lower connecting plate assembly; the upper connecting plate assembly and the lower connecting plate assembly are fixedly arranged on the connecting box cover and the lamp casing respectively; an electric channel which is formed by the contact of an electrical conduction pole and a movable contact plane pressure is formed between the upper connecting plate assembly and the lower connecting plate assembly; the lamp casing and the connecting box cover are in screw connection to cause a fixedly connected component not to be arranged between the connecting box cover and the lamp casing. The utility model has the advantages of convenient installation, convenient replacement, and convenient maintenance.
Description
The utility model relates to a kind of flame-proof type illuminating lamp.
The flame-proof type lighting is a kind of mine that is used for, there is the illuminations of the environment of strict demand in oil fields etc. to safety, have a wide range of applications, but present flame-proof type illuminating lamp generally has only a terminal plate, the lamp socket lead-in wire all connects thereon with electric power incoming line, and terminal plate is fixed on the lamp housing, therefore after carefully connecting the wire, screw in the lamp housing process, electric power incoming line also and then rotates to cause to tangle together and easily the end of a thread is pulled from binding post, hidden danger causes the accident, on the other hand, in case light fixture is out of order when needing maintenance or replacing, lamp housing need be screwed off and pulls down electric power incoming line, very inconvenience, especially more apparent outstanding when the position of lamp installation is not easy to operate.
The purpose of this utility model be for overcome deficiency that above-mentioned prior art exists provide a kind of have rational in infrastructure, safe and reliable, for ease of maintenaince save artificial novel flame-proof type lighting with changing.
The utility model purpose reaches by following scheme: the terminal plate assembly is divided into upper wiring board assembly and following terminal plate assembly, upper wiring board assembly and following terminal plate assembly are fixedly mounted on respectively on connector cover inner chamber and the lamp housing, between the upper and lower terminal plate assembly by being located on its opposite face respectively and the applanation of the pair of conductive utmost point of position correspondence and a pair of movable contact contacts electric path in constituting from terminal box to lamp housing.
Owing to adopted said structure, the member that between connector cover and lamp housing, is not fixedly connected, therefore when light fixture need keep in repair or change, the power line that need not to dismantle takes off whole lamp, get final product and only need screw off lamp housing, improve efficient, and also can not cause that power line tangles during the turn lamp housing and the pulling of the end of a thread, avoided accident potential.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the utility model example structure reference diagram.
Accompanying drawing 2 is the embodiment partial sectional view.
In the present embodiment, last conductive connector 5,6 are pressed on the disk terminal plate 2 by the vertical embedding of two conducting circular cylinder, wherein conductive connector 5 is located at disk terminal plate 2 circle centre positions, one end center is provided with the single head screw and is used for fixing inlet wire, the other end passes disk terminal plate 2 and exposes and exceeds bottom surface formation conductive electrode 3, conductive connector 6 is located at conductive connector 5 one sides, the center is provided with tapped through hole, one end is used for fixing another inlet wire, the other end is mutually neat with last disk terminal plate 2 bottom surfaces, conductive electrode 4 is installed the earflap thickness and is equaled the annulus that conductive connector 5 exposes height and constitute by uniform three an of outer, and be installed in disk terminal plate 2 bottom surfaces symmetrically, one of them earflap and conductive connector 6 are connected by screw and reach the electric UNICOM of going up, lower disc terminal plate 13 fronts are provided with two grooves of isolating mutually, the vertical embedding of reverse side is pressed with two ends and is provided with screw and extends the interior conducting circular cylinder formation conductive connector 10 of groove, 11, be respectively equipped with location-plate 8 in the groove, on 17 conducting circular cylinder that are fixed in the groove, location-plate 8,17 are provided with guide hole, the position respectively with conductive plate 3,4 is corresponding, the centre is provided with two movable contacts 14 on outer convex shoulder rank, the outer sheathed spring 9 of 15 hypomeres is placed in the guide hole, two movable contacts 14,15 respectively by electroconductive elastic sheet 12,18 with groove in the electric UNICOM of conducting circular cylinder, be stamped gland 16 on it, gland 16 is provided with and the corresponding spacing guide hole in location-plate 8 guide hole positions, movable contact 14,15 respectively via this hole and conductive electrode 3, the contact of 4 applanations, whole terminal plate assembly down is fixedly installed in lamp housing 1 neck.
