Abstract

The utility model discloses a ceramic lamp bulb socket structure, which comprises a ceramic lamp bulb socket, a metal conducting shell body arranged in the ceramic lamp bulb socket, and positive and negative power cord connection points connected with the conducting shell body. The side and the bottom of the metal conducting shell body are respectively provided with circular through holes; the positive power cord connection point and an insulating ring piece, a conducting copper hollow ring piece and rivets are combined together by the bottom circular through hole; the negative power cord connection point is fixed at the side circular through hole portion through rivets. Adopting the technical proposal can achieve the purposes of prolonged lifetime and safe assembly. The utility model is the improvement of the existing lamp bulb socket structure.

Description

The ceramic bulbs seat

The utility model belongs to daily class, relates in particular to a kind of architecture advances of ceramic bulbs seat.

At present, at the seen bulb seat in general market, shown in Fig. 2 A, Fig. 2 B, its bulb seat A shell is to make with plastic material, the ccontaining metallic conduction housing B in inside, metallic conduction housing B bottom is provided with two perforation, connects respectively to establish a positive power line C contact and a negative power line D contact; Yet promptly can find after ordinary consumer uses: the caliber specification is when 12mm is following in this bulb seat of first A, then positive power line C contact and negative power line D contact will all be located at very narrow place, metallic conduction housing B bottom, form the situation of conducting electric shock improperly during easily because of the assembling bulb and cause by the danger of electricity; It two is that this shell system is made with plastic material, begins to produce the embrittlement situation of breaking after using a period of time then, therefore cause in it ccontaining metallic conduction housing B without any protection, as easy as rolling off a log generation electric leakage is dangerous.

The purpose of this utility model provides a kind of safety, long ceramic bulbs seat of life-span.

For achieving the above object, the utility model is taked following design: the structure of this ceramic bulbs seat comprises that the ceramic bulbs seat reaches interior ccontaining metallic conduction housing and connects the positive and negative power line contact of establishing with this conductive shell, be respectively equipped with the circle perforation at metallic conduction housing side and bottom, bottom circle perforation combines the positive power line contact by an insulation ring plate, the hollow ring plate of conductive copper, rivet, the negative power line contact is fixed in perforation place of side circle by rivet.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 B is a structure cutaway view of the present utility model

Fig. 2 A is the structural representation of prior art ceramic bulbs seat

Fig. 2 B is a prior art ceramic bulbs seat cutaway view

Shown in Figure 1A, Figure 1B, the utility model is a ccontaining metallic conduction housing 2 in the ceramic bulbs seat 1 that a ceramic material that is hollow hole 11 shapes is made, these metallic conduction housing 2 sides and bottom are respectively equipped with a

circle perforation

21,22, negative power line 31 contacts are fixed in circle perforation 21 places by rivet 24, bottom circle perforation 22 combines by an insulation ring plate 23, the hollow ring plate 24 of conductive copper, rivet 2B etc. then with positive power line 32 contacts.

The utility model has the advantage of in the whole tube face 1 to coat with ceramic material, can prevent because making for a long time With and produce the embrittlement breakage, and by the close positioning of the hollow ring plate 24 of conductive copper and rivet 2B, and have phase When good conduction polarization, simultaneously the power line 31 of two opposed polarities, 32 contacts are at right angles Open sow discord every, think to be provided at unlikely generation conducting Danger Electric shock risk of when assembling, so reach life-saving and The purpose of safety assembled.

Claims

1, a kind of structure of ceramic bulbs seat, comprise ceramic bulbs seat and interior ccontaining metallic conduction housing and connect the positive and negative power line contact of establishing with this conductive shell, it is characterized in that: be respectively equipped with the circle perforation at metallic conduction housing side and bottom, bottom circle perforation combines the positive power line contact by an insulation ring plate, the hollow ring plate of conductive copper, rivet, the negative power line contact is fixed in perforation place of side circle by rivet.
