Abstract

The utility model relates to a bakelite lamp cap which includes a metal sleeve shell, an insulating body, a conductive cap and a conducting wire. A through hole is arranged at the top of the metal sleeve shell; the insulating body is formed by bakelite with compression molding and is provided with a wire entering hole perforating through the insulating body which is fixedly arranged in the through hole of the metal sleeve shell. The conductive cap is arranged at the top of the insulating body; the conducting wire is electrically connected with the conductive cap and enters into the metal sleeve shell through the wire entering hole of the insulating body. The bakelite replaces the plastic, glass as the insulating material; thereby, the character of high temperature enduring and environment protecting of the bakelite is fully utilized, and the safety is greatly increased. The utility model can be widely used in the high-power floodlight field.

Description

A kind of bakelite lamp holder

Technical field

The utility model relates to the lamp holder art, is meant the bakelite lamp holder of the wooden one-tenth insulator of a kind of electricity consumption especially.

Background technology

As everyone knows, lamp holder is the link as bulb and lamp socket; Traditional lamp holder is formed by metal casing, conductive cap, conductor wire and with conductive cap, the affixed all-in-one-piece glass insulator in metal casing insulation ground, owing to glass ware forming dimensional uniformity difference causes cooperating deviation big, and the glass insulator manufacturing needs high-temperature fusion, need the corresponding energy of waste because of heat glass so on the one hand, as electric energy etc., in melting process, can cause environmental pollution on the other hand, obviously not meet the demand of advocating environmental protection; Glass insulator also easily has crack or broken phenomenon to take place simultaneously, causes decreasing insulating, has hidden danger; Therefore, industry proposes to use general plastics instead of glass to make the design of insulator at present, but, because the resistance to elevated temperatures of general plastics is relatively poor, cause to be applied in some high-power illumination lamps, so plastics are to be difficult to replace glass material in high-power illumination lamp field, and by this, how overcoming problem high temperature resistant and environmental protection again is the current problem of demanding improvement urgently of industry.

The utility model content

The utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide a kind of high temperature resistant and bakelite lamp holder environmental protection again.

For realizing above-mentioned purpose, the utility model is taked following technical scheme:

A kind of bakelite lamp holder, comprise metal casing, insulator, conductive cap and conductor wire, this metal casing top offers through hole, above-mentioned insulator is the bakelite material, be integrative-structure, itself and above-mentioned metal casing one extrusion molding, this insulator has an entrance hole that runs through this insulator, this insulator is fixedly arranged in the through hole of above-mentioned metal casing, above-mentioned conductive cap is installed on the top of insulator, and above-mentioned conductor wire is electrically connected on this conductive cap and along the entrance hole on the insulator and puts in the metal casing.

Above-mentioned metal casing outer wall is provided with screw thread.

Therefore, so the advantage of the utility model is being replaced plastics, glass as insulator by bakelite, make full use of the characteristics such as high temperature resistant, environmental protection of bakelite, thereby improve the fail safe of use, can be widely used in high-power illumination lamp field.

Description of drawings

Fig. 1 is the utility model cross-sectional schematic.

The drawing reference numeral explanation:

1, metal casing 11, top 11a, through hole 12, outer wall 12a, screw thread

2, insulator 2a, entrance hole 2b, top

3, conductive cap

4, conductor wire

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 1 to shown in Figure 3, a kind of bakelite lamp holder comprises metal casing 1, insulator 2, conductive cap 3 and conductor wire 4, wherein:

Metal casing 1 is made of one piece by metal material, and its top 11 offers through hole 11a, and its stack shell outer wall 12 is provided with screw thread 12a.

Insulator 2 is made for the bakelite material, is integrative-structure, and wherein bakelite is to use powdered resin, adds wood sawdust, asbestos or potter's clay etc. and mixes Hou, at high temperature extrudes finished product with mould; The insulator 2 of institute's moulding is to have an entrance hole 2a who runs through this insulator, and this insulator 2 is fixedly arranged on again among the through hole 11a of above-mentioned metal casing 1.

Conductive cap 3 is installed on the top 2b of insulator 2.

Conductor wire 4 is to be electrically connected on the above-mentioned conductive cap 3, and puts in the metal casing 1 along the entrance hole 2a on the insulator 2.

Wherein, above-mentioned each structure processing assembly is as follows: metal casing 1 is put into the insulator 2 that mould and bakelite at high temperature extrude integrative-structure in the lump, then conductor wire 4 one ends are electrically connected with conductive cap 3, the other end puts in the metal casing 1 along the entrance hole 2a of insulator 2, tightens up conductive cap 3 again and gets final product.

The utility model design focal point is to replace plastics, glass as insulator by bakelite, makes full use of the characteristics such as high temperature resistant, environmental protection of bakelite, thereby improves the fail safe of use, can be widely used in high-power illumination lamp field.

The above, it only is the preferred embodiment of a kind of bakelite lamp holder of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
