Description of drawings
Fig. 1 is the assembling sketch map of the antislip insert structure that provides of the embodiment of the invention;
Fig. 2 is the embodiment of the invention binding post, insulating part and the external fastening element three's that provide a decomposing schematic representation.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Consult illustrated in figures 1 and 2ly, a kind of antislip insert structure that the embodiment of the invention provides comprises the binding post 1 of metal material, the insulating part 2 of plastic cement material and the external fastening element 3 of metal material; Said binding post 1 is used for power delivery to the lamp light source chamber (not shown) with light fixture wire connection cavity (not shown); Said insulating part 2 and external fastening element 3 all offer cavity, and said binding post 1 fixed cover is located in the said insulating part 2, and said insulating part 2 fixed covers are located in the said external fastening element 3; Said binding post 1 one ends are positioned at said wire connection cavity; The other end is positioned at said light-source chamber, and said binding post 1 two ends are processed with the opposite screw thread of rotation direction respectively, for example; When binding post 1 one ends were left hand thread, the other end was a right-handed thread; When binding post 1 one ends were right-handed thread, the other end was a left hand thread.
As depicted in figs. 1 and 2; Concrete fixing means between said insulating part 2 and the external fastening element 3 is: said insulating part 2 outer surfaces are installed with the fin 21 of at least one axial setting; Said external fastening element 3 inner surface axials offer groove 31 consistent with said fin 21 quantity and that engage with said fin 21, and during assembling, the fin 21 on insulating part 2 outer surfaces fastens with the groove 31 on external fastening element 3 inner surfaces; Thereby realize being fixedly connected between insulating part 2 and the external fastening element 3; And when insulating part 2 received revolving force or revolving force to the right left, insulating part 2 all can't rotate in external fastening element 3, has guaranteed assembly reliability.
As shown in Figure 1; Further; Said external fastening element 3 is fixedly arranged on the installing plate 4 between said wire connection cavity and the light-source chamber; Its concrete fixing means is: said external fastening element 3 outer surfaces are processed with external screw thread, offer the internal thread hole that matches with the external screw thread of said external fastening element 3 on the said installing plate 4, are threaded between said external fastening element 3 and the installing plate 4.
Particularly, said binding post 1, insulating part 2 and external fastening element 3 threes are one-body molded through inserting Shooting Technique (insertmolding), and after the moulding, the plastic rubber material of insulating part 2 tightly is wrapped on binding post 1 and the external fastening element 3, make connect between the three more firm.
As shown in Figure 1; Further; The end that said binding post 1 is positioned at wire connection cavity is provided with first conducting terminal 5, is fixedly connected through first screw 6 between said binding post 1 and first conducting terminal 5, and said first conducting terminal 5 is electrically connected with components and parts in the said wire connection cavity.In like manner, the end that said binding post 1 is positioned at light-source chamber is provided with second conducting terminal 7, is fixedly connected through second screw 8 between said binding post 1 and second conducting terminal 7, and said second conducting terminal 7 is electrically connected with components and parts in the said light-source chamber.Therefore; The present invention has realized the purpose that the components and parts in the wire connection cavity are electrically connected with components and parts in the light-source chamber through binding post 1; Be arranged because the wire connection cavity of light fixture and light-source chamber are divided, thereby guaranteed that the light fixture that this binding post 1 is housed can be applied to explosion-proof occasion.
The concrete operation principle of antislip insert structure provided by the invention is following:
(1) as depicted in figs. 1 and 2; When using first screw 6 that first conducting terminal 5 is installed, because the thread rotary orientation at binding post 1 two ends is opposite, when first screw 6 is left-handed; Binding post 1 also can receive revolving force left; Because the ridge orientation of the right-handed thread on the binding post 1 is opposite with the left hand direction of first screw 6, therefore, the right-handed thread on the binding post 1 plays the effect of binding post 1 to anticlockwise that stop; And binding post 1 and insulating part 2 more closely are fixed together, and binding post 1 the rotation phenomenon of skidding can not occur; When 6 dextrorotation of first screw; Binding post 1 also can receive revolving force to the right; Because the ridge orientation of the left hand thread on the binding post 1 and the dextrorotation of first screw 6 are in the opposite direction, therefore, the left hand thread of binding post 1 plays the binding post 1 dextrorotary effect that stops; And binding post 1 and insulating part 2 more closely are fixed together, and binding post 1 the rotation phenomenon of skidding can not occur yet; Through above analysis, first screw, 6 left-handed or dextrorotation no matter, binding post 1 the rotation phenomenon of skidding can not occur, and has guaranteed the assembly reliability between first conducting terminal 5, binding post 1 and insulating part 2 threes.
(2) in like manner, when using second screw 8 that second conducting terminal 7 is installed, second screw, 8 left-handed or dextrorotation no matter, binding post 1 the rotation phenomenon of skidding can not occur yet, and has guaranteed the assembly reliability between second conducting terminal 7, binding post 1 and insulating part 2 threes.Description through above-mentioned steps (1) and step (2) can know, the electric power of the wire connection cavity of light fixture can be respectively normally be passed to the light-source chamber of light fixture through first conducting terminal 5, binding post 1 and second conducting terminal 7, thereby has guaranteed the operate as normal of light fixture.
(3) in the light fixture use; When light fixture runs into when shaking situation by force; Binding post 1 can receive revolving force to the left or to the right; Right-handed thread on the binding post 1 or left hand thread can stop binding post 1 to rotate to the left or to the right well; Guarantee the tight fixed connection between binding post 1, insulating part 2 and first conducting terminal 5 (or the second conducting terminal 7) three, thereby the electric power of the wire connection cavity of light fixture can be respectively normally be passed to the light-source chamber of light fixture through first conducting terminal 5, binding post 1 and second conducting terminal 7, thereby have guaranteed the operate as normal of light fixture.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
