Abstract
The utility discloses a plastic lamp holder made of a plastic shell and a metal shell fixedly connected with each other to constitute a whole lamp shell. Power line passes through through-hole at plastic shell top and is fixedly connected with electric connection contact positioned upper of the through-hole; metal shell is fastened in groove peripherally disposed at tail of plastic shell. A pair of plugs insert tightly in plastic shell. The utility substitutes plastic shell for glass insulator, avoids hidden trouble of fragility of glass, and has better insulation effect; the utility adopts fixedly connected plastic shell and metal shell as a whole lamp shell, promotes intensity of lamp holder by substituting plastic shell for original part of metal shell; the two plugs are inserted into plastic shell at last procedure, which can effectively reduce shedding rate of plug and promote qualification rate of products.
Description
Technical field
The utility model relates to a kind of light fixture, especially refers to a kind of architecture advances of bayonet cap.
Background technology
Existing lamp holder is as shown in Figure 1: it mainly is made up of metal shell 6, electric conductor 7 and an insulating barrier, described insulating barrier adopts vitreous insulator 8, and metal shell 6 inner surface tops connect as one with electric conductor 7 converged fixed by vitreous insulator 8.In actual production, adopt vitreous insulator 8 hot melts, converged fixed connects metal shell 6 and electric conductor 7.Its processing technology requires high, and product qualified rate is low; Because there is the frangible hidden danger of easily splitting in vitreous insulator 8, and has influenced insulation effect, the shortcoming that exists the security performance shakiness to lean in actual use.
The utility model content
At the deficiencies in the prior art part, the utility model provides a kind of environmental protection lamp holder simple in structure, and this lamp holder effectively reduces the assembly technology difficulty, improved the finished product rate greatly, and security performance is reliable.
For achieving the above object, technical solutions of the utility model are:
A kind of Plastic lamp socket mainly is made up of lamp housing, electric conductor and insulator, and described insulator is a plastic casing, and it fixedlys connected the whole lamp housing of formation with a metal shell; The plastic casing top offers the power line through hole, and a pair of electrical connection contact connects power line and is fixed in the plastic casing top, and a pair of plug is fixed on the plastic casing two side.
Described plastic casing afterbody ring is established groove, and metal shell is arranged in this groove.
The plug tight fit is inserted in plastic casing.
The usefulness of technique scheme is:
The utility model has been abandoned the technology of available technology adopting nature of glass insulator, replaces nature of glass insulator with plastic casing, and this plastic casing is fixedlyed connected the whole lamp housing of formation with metal shell, assembly structure simply, use the material environmental protection; Part with metal shell in the plastic casing replacement prior art makes lamp holder more durable.
Description of drawings
Fig. 1 is a prior art holder structure schematic diagram;
Fig. 2 is the utility model plan structure schematic diagram;
Fig. 3 looks up structural representation for the utility model;
Fig. 4 is the A-A sectional structure schematic diagram of Fig. 2;
Fig. 5 is the B-B sectional structure schematic diagram of Fig. 2.
Embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
A kind of Plastic lamp socket shown in Fig. 2,4,5 mainly is made up of lamp housing, electric conductor and insulator, and described insulator is a plastic casing 1, and it fixedlys connected the whole lamp housing of formation with a metal shell 2.This plastic casing 1 top offers power line through hole 11, and a pair of electrical connection contact 3 connects power line and is fixed in power line through hole 11 tops; Plastic casing 1 afterbody is equipped with groove, and metal shell 2 is arranged in this groove.Described as shown in Figure 3 plastic casing 1 madial wall is provided with a pair of reinforcement 12, and 12 of reinforcements are connected with stiffener 4, and a pair of plug 5 tight fits are inserted in reinforcement 12.
The utility model replaces nature of glass insulator of the prior art with plastic casing 1, the hidden danger that original Glass breadks easily of having forgone easily splits, and insulation effect is better, uses the material environmental protection; Adopt plastic casing 1 to fixedly connected the whole lamp housing of formation with metal shell 2, assembly structure is simple; With the part of the original metal shell 2 of plastic casing 1 replacement, improved the intensity of lamp holder; Just plug into plastic casing 1 because two plugs 5 are the finishing operations in technology, can effectively reduce the ratio that plug 5 comes off, improved product percent of pass.
