Abstract
The utility model discloses a glass insulator soldering-free lamp holder, which comprises a thread head, a glass insulator, a metal top cover and a metal bump. The center of the metal bump is provided with a small hole. The glass insulator is positioned on the top of the thread head and is firmly combined with the thread head. The metal bump is positioned at the middle part of the glass insulator, is convex upwards and is firmly combined with the glass insulator. The shape and the size of the metal top cover are matched with the convex part upwards on the metal bump and the metal top cover are just buckled on the convex part upwards. The utility model does not adopt solder, eliminates damage caused by the solder to the environment, saves energy and is suitable for lamp bulbs with various powers.
Description
Technical field
The utility model relates to a kind of illuminating industry lamp holder, and particularly a kind of glass insulator is exempted from the blowtorch head.
Background technology
At present, the existing blowtorch head of exempting from includes a chain for binding criminals line head, insulator and casting coping three parts, but existing insulator adopts plastic production to form mostly, can only be applicable to low power bulb, and can not be used for powerful bulb, because the heat that powerful bulb is produced after long-time the use can be softening with the insulator of plastics, even fusing, and being connected between the insulated part of plastics and the crown cap is not very firm, and be loosening easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of glass insulator and exempts from the blowtorch head, does not adopt scolding tin, has eliminated the harm that scolding tin causes environment, and has saved the energy; And be applicable to the bulb of various power.
The utility model technical scheme that adopts of dealing with problems is: a kind of glass insulator is exempted from the blowtorch head, comprise thread head, glass insulator and casting coping, also comprise a metal coupling, the center of described metal coupling is provided with aperture, described glass insulator be positioned at thread head the top and with the thread head strong bonded, described metal coupling be positioned at glass insulator middle part and protruding upward and with the glass insulator strong bonded, above the shape of described casting coping and size are complementary with metal coupling part protruding upward and just in time are held in.
As a kind of preferred, described metal coupling part protruding upward is cylindrical, above described casting coping is the disc that is complementary with metal coupling part protruding upward and just in time is held in.Closely cooperate between cylindrical metal projection and the casting coping, link more firm, difficult loosening.
A chain for binding criminals line head of the present utility model, glass insulator and metal coupling, being adopted when body formed the mode of cast to link by glass insulation is an integral body, strong bonded, leave the power supply lead wire hole in the middle of the glass insulator, communicate with the set aperture in metal coupling center, casting coping is closely buckled in metal coupling part protruding upward, be fixed together by interference fits and metal coupling and power supply lead wire, become an electrode, removed the scolding tin between power supply lead wire and the lamp holder from, eliminate the harm that scolding tin causes environment, and saved the energy.
The beneficial effects of the utility model are: the structure that has adopted metal coupling to match with casting coping, promptly need not carry out scolding tin again, and reach the effect of scolding tin equally, eliminate the harm that scolding tin causes environment, and saved the energy; And the material of insulator adopts glass, promptly needn't consider the size issue of bulb power, makes it to be applicable to the bulb of various power.

Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 for the utility model embodiment not with the schematic diagram of casting coping.
Fig. 3 is the structural representation of the utility model embodiment casting coping.
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment
As shown in Figure 1 and Figure 2, a kind of glass insulator is exempted from the blowtorch head, comprises thread head 1, glass insulator 2, projection 3 and casting coping 4, and this projection 3 all can be become by iron or copper with casting coping 4.This projection 3 be positioned at glass insulator 2 middle parts and protruding upward and with glass insulator 2 strong bonded, its projection is cylindrical, is provided with aperture at the center of projection 3, is used to wear power supply lead wire and uses; Glass insulator 2 be positioned at thread head 1 the top and with thread head 1 strong bonded, the shape of the casting coping 4 (as shown in Figure 3) that is made of copper and size are for the projection 3 cylindrical disc that is complementary protruding upward and above just in time being held in.
In the practical application, the utility model is threaded with the bulb glass head, and power supply lead wire passes a little from the aperture that projection 3 centers are provided with, and bending is coated the appropriate amount of fluid conducting resinl to projection 3 table planes, covers the casting coping 4 that is made of copper and gets final product.
