Abstract
The utility model discloses a bayonet lamp holder, including the bail, a housing, insulator and wire, the bail symmetry sets up in the casing both sides, the casing is both ends open-ended barrel, the insulator is moulded plastics at the top of casing, be equipped with on the insulator and link up two wire holes inside and outside the lamp holder respectively, the position of two electrodes is corresponding in two wire hole positions and the bayonet socket lamp stand, be equipped with electrically conductive cap on the outside port of two wire holes respectively, be equipped with on the terminal surface of insulator with the recess of electrically conductive cap looks adaptation, the lower edge of electrically conductive cap is arranged in this recess, the wire passes the wire hole and is connected with electrically conductive cap electricity respectively. The bayonet lamp holder directly injects the insulator at the top of the shell, so that the consumption of insulator materials is saved, the working procedures are reduced, the connection between the insulator and the shell is more reliable, the production qualification rate is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of bayonet cap.
Background technology
Bayonet cap is the vitals of incandescent lamp and electronic energy-saving lamp, traditional bayonet cap comprises bail, housing, insulator and lead, bail is symmetricly set in the housing both sides, and insulator adopts glass or ceramic material to be full of in the whole housing, with the lead cast and be fixed in wherein.The bayonet cap of this structure, insulating material is wasteful, and because glass or ceramic material are easily broken, bad mechanical strength, rate of finished products is low in the production.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly simple in structurely is easy to assemble and bayonet cap that production cost is low.
For solving the problems of the technologies described above, the utility model provides a kind of bayonet cap, comprise bail, housing, insulator and lead, bail is symmetricly set in the housing both sides, housing is the cylindrical shell of both ends open, insulator is injection-moulded in the top of housing, insulator is provided with and connects two inside and outside wire guides of lamp holder respectively, the position of two electrodes is corresponding in two wire guide positions and the bayonet cap, be respectively equipped with conductive cap on the outside port of two wire guides, the end face of insulator is provided with the groove suitable with conductive cap, and the lower edge of conductive cap places this groove, and lead passes wire guide and is electrically connected with conductive cap respectively.
Conductive cap can be the cylinder of the uncovered other end sealing of an end, and suitable with it groove is an annular recess.
Insulator is directly injection-moulded in the top of housing, and the consumption of having saved insulating material has reduced operation, makes insulator more reliable with being connected of housing, has improved the production qualification rate, has reduced production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the front view of the utility model bayonet cap.
Fig. 2 is the partial sectional view of Fig. 1.
Among the figure: 1 wire guide, 2 insulators, 3 conductive caps, 4 grooves, 5 bails, 6 housings.
Embodiment
As depicted in figs. 1 and 2, bayonet cap of the present utility model, comprise metal bail 5, metal shell 6, plastic insulation 2 and lead, bail 5 is symmetricly set in the both sides of housing 6, housing 6 is the cylindrical shell of both ends open, insulator 2 is injection-moulded in the top of housing 6, insulator 2 is provided with and connects two inside and outside wire guides 1 of lamp holder respectively, the position of two electrodes is corresponding in the position of two wire guides 1 and the bayonet cap, be respectively equipped with conductive cap 3 on the outside port of wire guide 1, the end face of insulator 2 is provided with the groove 4 suitable with conductive cap 3, the lower edge of conductive cap 3 places this groove 4, conductive cap 3 is preferably the cylinder of the uncovered other end sealing of an end, and groove correspondingly is an annular recess, and lead passes wire guide 1 and is electrically connected with conductive cap 3 respectively.
This lamp holder can also adopt other structure, can adopt ellipse or other shape as conductive cap, all falls into protection range of the present utility model.
