Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of safety screw lamp of the utility model, as shown in Figure 1, comprises cap part and lamp holder.As shown in Figure 2, cap part is made up of the outside insulating annulus 4 of the inner side insulating annulus 2 in the middle of the lamp holder central contact 3 at lamp holder side screw thread 5 and lamp holder top, lamp holder endless belt contact 1 and two contacts and periphery, lamp holder endless belt contact 1, and single unit system also should comprise the luminous element 6 be connected with lamp holder side screw thread 5; Lamp holder inner lead 7 top is welded with lamp holder central contact 3 and lamp holder endless belt contact 1 respectively, and bottom is connected to form path with luminous element 6 inner lead respectively.Lamp holder endless belt contact 1 is embedded in the insulation board of lamp holder top, and lamp holder endless belt contact 1 level height is consistent with lamp holder top planes level height; Lamp holder central contact 3 is embedded in the insulation board of lamp holder top equally, and lamp holder central contact 3 is slightly protruded and lamp holder top planes.The diameter of lamp holder central contact 3, the width of inner side insulating annulus 2, the width of lamp holder endless belt contact 1, the width of outside insulating annulus 4, according to when conductive contact safety and stability and lamp holder maximum gauge, above four sizes really normal root rationally determine that size is distributed, and will cooperation corresponding to lamp socket metal spring leaf 9, the width design of outside insulating annulus 4 should be narrower.Lamp holder side screw thread 5 should be isolation material, sometimes according to the variety classes of luminous element 6 and character or metal or other conductive material must be adopted also to be fine under manufacturing the situation such as special process, specific condition use, but to carry out and inside and outside wire insulation process.Lamp holder top have certain thickness insulation board embedded lamp holder central contact 3 and lamp holder endless belt contact 1, the top of insulation board and lamp holder side screw thread 5 coordinates.Whole safety screw lamp holder only has lamp holder central contact 3 and lamp holder endless belt contact 1 to conduct electricity, and the fail safe that above this design not only increases lamp holder also saves metal material.As shown in Figure 3, the center of lamp socket metal spring leaf 9 has central through hole 15, four metallic conduction sheets are evenly provided with around central through hole 15, as shown in Figure 4, lamp socket constituting parts mainly contains: lamp socket insulation shell 8, lamp socket metal spring leaf 9, set bolt 10, lamp socket upper cover 11, outer conductor entrance 12, binding post 13, lamp socket central contact 14.Lamp socket insulation shell 8 and lamp socket upper cover 11 are all adopt insulating material molding to cast, screw thread inside lamp socket insulation shell 8 lower part is engaged mutually with safety screw lamp holder side screw thread 5, and the screw thread outside lamp socket insulation shell 8 upper part is engaged mutually with the screw thread inside lamp socket upper cover 11.
Operation principle of the present utility model is: lamp socket metal spring leaf 9 loads bottommost from lamp socket insulation shell 8 lower part, four clockwise reed contact pin outwardly, by set bolt 10 simultaneously through the bolt hole on lamp socket metal spring leaf 9 and the bolt hole on lamp socket interlayer, then the nut or the binding post 13 that screw in lamp socket top carry out fastening, lamp socket central contact 14 is passed lamp socket central through hole and is screwed in lamp socket top binding post 13 and carries out fastening, finally lamp socket upper cover 11 and lamp socket insulation shell 8 is screwed.Wherein set bolt 10 is two, and one of them screws in binding post 13, and another screws in nut, and external wire enters lamp socket by outer conductor entrance 12, and is fixed by binding post 13 screwing.
