Abstract
The utility model relates to a ceramic lamp cap which is used for the fixed connection of bulb and conductively connected with the filament of bulb each other. The lamp cap comprises a cylinder and a conductive terminal, wherein the cylinder is made of a ceramic material, a closed end is formed at one side of the cylinder, the closed end is provided with a through-hole that one end of the filament can pass through. The outer periphery of the cylinder is formed with external thread and grooves sunk in the peripheral edge face of the external thread. The conductive terminal is accommodated fixedly in the grooves, and partially exposed from the outer peripheral edge faces of the external thread. One end of the conductive terminal is used to connect with the other end of the filament, thereby reducing frictional abrasion between the conductive terminal and the lamp holder so as to add contact effect and prolong service life.
Description
Technical field
The utility model relates to a kind of light fixture, relates in particular to a kind of being used for for the fixedly connected holder structure of bulb.
Background technology
Existing holder structure mainly comprises fitting and dead ring in filament external piece, the filament.The filament external piece is made by metal materials such as copper, and the local outer surface that is coated on dead ring, and the periphery wall at the filament external piece forms external screw thread in addition.Fitting then is provided with at interval with the filament external piece in the filament, and is connected in the center of top place of dead ring.Be welded to each other with outer filament with the interior filament of bulb respectively with the filament external piece by fitting in the filament and be connected, can reach bulb and lamp holder combining structure.
Yet, existing holder structure, on using, reality still has following shortcoming: because its external screw thread by external piece is done being rotatably connected of wholecircle week with the internal thread (not shown) of lamp socket, and make friction consume to each other quite big, often be at screw-in for several times or after screwing out, promptly make internal thread and external screw thread produce the loose contact phenomenon.In addition, it is numerous that it forms assembly, and the cost of manufacture and the material cost of each assembly not only arranged, and also needs to expend the great amount of manpower assembly cost.In addition, the heat-resisting quantity of fitting and external piece and bad in it under continuing for a long time to use, very easily because overheated and produce and damage, and significantly reduces useful life.
The utility model content
The purpose of this utility model is to provide a kind of ceramic-type holder structure, and it is by being located in conducting terminal in the groove of cylindrical shell, make when cylindrical shell screws in lamp socket, can reduce the friction loss between conducting terminal and the lamp socket, and then increase its contact effect, prolong its useful life.
Another purpose of the present utility model is to provide a kind of ceramic-type holder structure, and its cylindrical shell is a ceramic material, thereby can bear higher heat resisting temperature, and the heat of filament or bulb can be derived dissipation fast, thereby increases the useful life of bulb.
Another purpose of the present utility model is to provide a kind of ceramic-type holder structure, and it is simple in structure, assembling is easy, thereby significantly reduces material cost and manufacturing cost.
In order to reach above-mentioned purpose, the ceramic-type holder structure that provides according to the utility model, be used for for bulb fixedly connected, and with the filament mutual conduction of described bulb, comprise: cylindrical shell, be ceramic material, a side of described cylindrical shell forms blind end, be provided with the through hole that passes for described filament one end at described blind end, form external screw thread and be absorbed in the groove of described externally threaded circumferential surface in the outer peripheral edges of described cylindrical shell in addition; And conducting terminal, be installed with in the groove that is fixed in described cylindrical shell, and Local Convex exposing described externally threaded outer peripheral edges face, an end of described conducting terminal is used for being connected with the described filament other end.
The relative prior art of ceramic-type holder structure tool that provides according to the utility model has following advantage:
At first,, can reduce the friction loss between conducting terminal and the lamp socket, and then increase its contact effect, prolong its useful life owing to, make when cylindrical shell screws in lamp socket by conducting terminal is located in the groove of cylindrical shell.
Secondly,, and the heat of filament or bulb can be derived dissipation fast, thereby increase the useful life of bulb because its cylindrical shell is a ceramic material, thereby can bear higher heat resisting temperature.
Once more, this ceramic-type holder structure is simple in structure, assembling is easy, significantly reduces material cost and manufacturing cost.

Embodiment
Below in conjunction with accompanying drawing technology contents of the present utility model is elaborated, yet accompanying drawing is only for reference and the usefulness of explanation, is not to be used for the utility model is limited.
Fig. 1, Fig. 2 and Fig. 3 are respectively three-dimensional exploded view of the present utility model, combination schematic diagram and combination and analyse and observe., the utility model provides a kind of ceramic-type holder structure, and it mainly comprises cylindrical shell 10 and conducting terminal 20, wherein:
Conducting terminal 20 is made by conductivity good metal materials such as copper, and is made of a vertical section of connecting 21 and two head from the section of connecting 21, vertically extending respectively affixed section 22,23 at last two ends.The section of connecting 21 belows have protruded out and have connected a little 24, bend inwards respectively and form trip 25,26 at each affixed section 22,23 end in addition.Conducting terminal 20 is installed with in the groove 16, and by each affixed section 22,23 aforesaid each fixing hole 17,18 of cross-under respectively, utilize again each trip 25,26 respectively clip be clamped on cylindrical shell 10 internal faces, connect a little 24 then protruding outer peripheral edges faces that expose external screw thread 15.
Figure 4 and 5 are respectively combination appearance figure and the assembled sectional view that the utility model is connected in bulb.Holder structure of the present utility model can be fixedly connected for bulb 5, and bulb 5 has interior filament 51, outer filament 52 and separates the newel 53 of interior filament 51 and outer filament 52.Earlier interior filament 51 is passed from through hole 13 during combination, after again affixed section 23 of conducting terminal 20 being welded to each other with outer filament 52, respectively each affixed section 22,23 is penetrated in first fixing hole 17 and second fixing hole 18 again, be clamped on cylindrical shell 10 internal faces by each trip 25,26 clip, and utilize and respectively to embed post 14 and embed the shrinkage pool of bulb 5 respectively and fix.At last, interior filament 51 is welded on the through hole 13, can finishes combining of holder structure and bulb 5.
