Detailed description of the invention
Referring to figs. 1 through Fig. 7, the utility model embodiment is described further.
Novel explosion-proof lamp described in the present embodiment, with reference to Fig. 2 and Fig. 3, comprise housing 1, light source assembly 2, power supply module 3, light source assembly 2 is preferably LEF light source, described power supply module 3 is fixedly connected in housing 1, described light source assembly 2 comprises mount pad 21, described mount pad 21 is provided with round plate 22, the sidewall of described round plate 22 is provided with external screw thread, be threaded connection between described housing 1 and round plate 22, described round plate 22 surface is fixed with the positive strap 23 of electrical connection light source assembly 2, negative straps 24, positive strap 23 is positioned at round plate 22 center, negative straps 24 is positioned at the outer shroud of positive strap 23 in annular, positive strap 23 and negative straps 24 are by being adhesively fixed on round plate 22, described power supply module 3 is provided with positive terminal 31, anode connector 32, the axial orthographic projection of positive terminal 31 falls within positive strap 23, the axial orthographic projection of anode connector 32 falls within negative straps 24, positive terminal 31, anode connector 32 screws tight and positive strap 23 with housing 1 and round plate 22, negative straps 24 correspondence is formed conflicts.
Effect of the present utility model is, abandon tradition connects power supply module 3 and light source assembly 2 form by wire bonds, this programme by arrange on the mount pad 21 of light source assembly 2 round plate 22 for coordinate with housing 1 carry out screwing tight fixing, the positive strap 23 that is electrically connected with power supply module 3 and negative straps 24 is wherein fixed on round plate 22 surface, wherein positive strap 23 is positioned at the center of round plate 22, and negative straps 24 is positioned at the outer shroud of positive strap 23 for annular; And power supply module 3 links with housing 1 for being fixedly connected in housing 1, namely housing 1 is when rotating and round plate 22 screws tight, power supply module 3 rotates with housing 1, and in this programme, positive terminal 31, anode connector 32 are conflicted with positive strap 23, the corresponding formation of negative straps 24 with screwing tight of round plate 22 with housing 1.Thus make to be threaded connection connection that housing 1 and round plate 22 can realize light source assembly 2 and power supply module 3 and be separated, the dismounting of this explosion-proof lamp convenient, convenient for maintaining.
And this programme middle shell 1 and mount pad 21 are split type, both are respectively used to fixed light source assembly 2 and power supply module 3, compare conventional art, due to welding lead between light source assembly 2 and power supply module 3, therefore, power supply module 3 must be fixed together with light source assembly 2, can not pull and draw to prevent wire from pulling apart, therefore mount pad 21 and housing 1 are generally integral type, and must first light source assembly 2 and power supply module 3 be connected before installing, both install together, increase assembly difficulty undoubtedly, then can mount pad 21 and housing 1 be set to split type by the technical program, respectively light source assembly 2 and power supply module 3 are installed, thus the assembling of this product convenient.
Above-mentioned power supply module 3 is fixed in housing 1 by bolt, screw etc., but in order to further facilitate the dismounting of this Novel explosion-proof lamp, is mainly the dismounting of power supply module 3, and the present embodiment is also made with and improves:
Further, as shown in Figure 6 and shown in Fig. 7, described housing 1 cylindrically, the inwall of described housing 1 is provided with cannelure 11, described power supply module 3 comprises cylinder blanket, and described shell radial direction is provided with the block tongue 33 for embedding in cannelure 11, and described cannelure 11 offers the breach 12 snapping in cannelure 11 for block tongue 33, the bottom of described cannelure 11 is also provided with locating slot 13, and described shell is provided with the elastomeric element by shrinking embedding or the locating slot 13 that contracts.Described elastomeric element comprises the groove 38 being arranged at side wall of outer shell, and Telescopic Fixed in the projection 34 of groove 38 opening part, and the spring 37 that supporting lug 34 outwards ejects, and described projection 34 is connected with the press section 35 for being installed with in groove 38.The opening part of described groove 38 is provided with the limited block 36 for preventing projection 34 from dropping.
Wherein, the axial restraint of power supply module 3 is by snapping in cannelure 11 by the block tongue 33 on its side wall of outer shell by breach 12, make block tongue 33 form inlay card with the sidewall of cannelure 11 by rotation again to fix, thus prevent the axial displacement of power supply module 3, during in order to ensure that housing 1 rotates, power supply module 3 can not arbitrarily rotate and cause block tongue 33 again go to breach 12 place and lose fixing, this programme is also provided with locating slot 13 in cannelure 11, snapping in locating slot 13 internal fixtion by the projection 34 on power supply module 3 makes the circumference of power supply module 3 be fixed, random rotation can not be there is.Operating process is as follows, when installing power supply module 3, by hand press section 35, projection 34 is shunk in groove 38, block tongue 33 is embedded in cannelure 11, turn to locating slot 13 place, decontrol press section 35, projection 34 embeds locating slot 13 internal fixtion by the elastic force automatic spring of spring 37, and the opening of groove 38 arranges limited block 36 and prevents from projection 34 from ejecting groove 38 completely causing loss.During dismantling power assembly 3, reverse operating.
Secondly, further, described positive terminal 31, anode connector 32 are in hemispherical, and described positive strap 23 center caves inward.Positive strap 23 center caves inward, and better plays the effect of location, and positive terminal 31 is not easy to depart from the position of positive strap 23.It should be noted that; above-mentioned positive strap 23 and negative straps 24 and the position relationship between positive terminal 31 and anode connector 32 can be corresponding in groups exchange; mode after exchange also belongs within design of the present utility model, should put protection domain of the present utility model under.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
