[embodiment]
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.A lot of details have been set forth in the following description so that fully understand the present invention.But the present invention can implement to be much different from alternate manner described here, and those skilled in the art can do similar improvement without prejudice to intension of the present invention in the situation that, so the present invention is not subject to the restriction of following public concrete enforcement.
Secondly, the present invention utilizes schematic diagram to be described in detail, when the embodiment of the present invention is described in detail in detail; for ease of explanation; the sectional drawing that represents device architecture can be disobeyed general ratio and be done local amplification, and described schematic diagram is example, and it should not limit the scope of protection of the invention at this.The three-dimensional space that should comprise in addition, length, width and the degree of depth in actual fabrication.
Refer to Fig. 1, an embodiment waterproof end plug 100 is mainly used in fixed cable, and it comprises roughly cylindrical main body 10.Main body 10 consists of the material that resiliently deformable can occur, such as rubber, resin etc.
See also Fig. 2, main body 10 offers a cylindrical hole 11 for cable is passed vertically.On the hole wall of through hole 11, be formed with three around the first sealed muscle 111 of through hole 11.Each first sealed muscle 111 is roughly ring, and its cross section is roughly inverted v-shaped.The spacing of the first adjacent sealed muscle 111 equates.When cable runs through, be arranged at through hole 11 when interior, three the first sealed muscles 111 can with the surperficial close contact of cable, thereby anti-sealing or other impurity enter inside electric appliance along the gap of cable and waterproof end plug 100, avoid the generation of short circuit or other unusual conditions.The quantity that is appreciated that the first sealed muscle 111 can be one, two, four or more.The shape of the first sealed muscle 111, except ring, can be also spirality.
In the present embodiment, two end faces up and down of main body 10 are respectively formed with one around the second sealed muscle 113 of through hole 11.
Above-mentioned waterproof end plug 100 can be applicable in light fixture, especially can be applied in some are had relatively high expectations to Safety performance and Environmental Conditions is comparatively severe light fixture.
Refer to Fig. 3, an embodiment light fixture 200 comprises lamp cylinder 210, be located at the end cap 230 of lamp cylinder 210 ends and through the cable 250 of end cap 230.
Lamp cylinder 210 is roughly cylindrical body.End cap 230 is roughly discoid, and it is fixedly installed on the upper end of lamp cylinder 210.Cable 250 is through end cap 230, and is connected with the part of light source in lamp cylinder 210.
Refer to Fig. 4, light fixture 200 also comprises the waterproof end plug 100 of being located on end cap 230.Cable 250 is through waterproof end plug 100.
See also Fig. 5, end cap 230 comprises plug bracket 231.In plug bracket 231, offer for the fixing groove 233 of waterproof end plug 100.The bottom surface 235 that groove 233 is contacted by the lower end surface of the main body 10 with waterproof end plug 100 and the locating face 237 contacting with the side of main body 10 surround.
Light fixture 200 also comprises cover plate 270.Cover plate 270 is roughly square plate, and it is fixed on end cap 230 by four screws 271.On cover plate 270, offer the cable-through hole 273 passing for cable 250.
During use, first make cable 250 through end cap 230, then waterproof end plug 100 is set on cable 250, and is positioned in the groove 233 of plug bracket 231, finally cover plate 270 is placed on end cap 230, and make cable 250 through cable-through hole 273.
When using screw-driver to tighten screw 271, the upper-end surface of the lower surface extruding main body 10 of cover plate 270, thereby make cover plate 270 and the second sealed muscle 113 close contacts that are positioned at main body 10 upper-end surfaces, therefore anti-sealing infiltrates from the gap between cover plate 270 and waterproof end plug 100.Meanwhile, be positioned at the second sealed muscle 113 of main body 10 lower end surfaces and bottom surface 235 close contacts of plug bracket 231, therefore anti-sealing infiltrates from the gap between plug bracket 231 and waterproof end plug 100.When cover plate 270 continues extruding waterproof end plug 100, because the side of main body 10 contacts with the locating face 237 of plug bracket 231 all the time, therefore main body 10 can be to through hole 11 radial contraction distortion, thereby make three first sealed muscles 111 and cable 250 close contacts, therefore anti-sealing infiltrates from the gap between cable 250 and main body 10.
The water-proof performance of above-mentioned light fixture 200 can reach IPX5 level.
The quantity that is appreciated that the second sealed muscle 113 that is positioned at each end face also can be over one.
Be appreciated that waterproof end plug 100 also can be applied to other electrical equipments outside light fixture 200, as computer, display device etc.
The above embodiment has only expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
