Abstract

The invention discloses a lamp head and a manufacturing method. The lamp head comprises a cylindrical ceramic insulating body, wherein the upper end of the ceramic insulating body is connected with a hollow metal shell; and a glass head is connected with the lower end of the ceramic insulating body. A necking structure is arranged at the lower end of the ceramic insulating body and an opening expanding structure is arranged at the upper end of the glass head; and the necking structure is in threaded connection within the opening expanding structure. The manufacturing method of the lamp head comprises the following steps of: firstly, fixedly connecting the ceramic insulating body with the glass head; and then, fixedly connecting the ceramic insulating body with the metal shell. According to the lamp head and the manufacturing method, the ceramic insulating body is screwed into the inner part of a thread of the glass head, and the fixation of the metal shell at the upper end of the product and the ceramic insulating body adopts a clamping structure and adopts a manner of fixing by glue. The manufacturing process is simple; the product graded rate is high; and the safety performance is good.

Description

Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of lamp holder, simple in structure, and security is higher, has also facilitated production.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of lamp holder, is characterized in that: comprise the ceramics insulator of tubular, described ceramics insulator upper end connects the metal shell of a hollow, and described ceramics insulator lower end connects a glass head.
As preferably, described ceramics insulator lower end is provided with throat structure, and described glass head upper end is provided with the structure of dehiscing, and described throat structure is threaded connection in the described structure of dehiscing.
As preferably, described throat structure outer wall is infundibulate, and described throat structure inwall is also infundibulate, and the infundibulate outer circumference surface bottom of described throat structure outer wall and inwall joins.
As preferably, the inner structural wall of dehiscing of described glass head is infundibulate, the hollow round table shape structure of described glass head bottom for protruding.
As preferably, the funnel-shaped structure that described housing bottom is hollow, housing bottom is provided with the flange that protrude at Yi Quanxiang center.
Preferably, described ceramics insulator top is provided with boss, and the external diameter of described boss is equal to or greater than the internal diameter of described flange, and described flange and described boss are fixed by glue.
Preferably, on described flange, interval 180 degree are provided with the dop that protrude at Liang Gexiang center.Described boss bottom outer circumference surface is provided with the draw-in groove snapping in for described dop.
The present invention also provides the manufacture method of above-mentioned lamp holder: first, ceramics insulator and glass head are connected and fixed, then ceramics insulator and metal shell are connected and fixed.
Concrete, the dehiscing of the throat structure that described ceramics insulator lower end arranges and the setting of glass head upper end is provided with screw connection structure between structure, and ceramics insulator and glass head are threaded connection structure and are connected and fixed.Described metal shell base flange is aimed at the boss of ceramics insulator, and boss is inserted in metal shell base flange, then rotation makes the dop of metal shell snap in the draw-in groove of ceramics insulator and adopt glue to fix.
It is inner that the present invention utilizes ceramics insulator to be threaded into glass head thread, and the fixedly employing interface arrangment of product upper end metal shell and ceramics insulator also adopts the hydropexic mode of glue.Its beneficial effect is:
1. adopt conventional E27/27 glass lamp holder, can be used alone;
2. adopt ceramic body to screw in the method for E27 lamp holder inside, manufacture craft is simple;
3. the product percentage of A-class goods is high, and security performance is good.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is the structural representation of lamp holder of the present invention;
Fig. 2 is ceramics insulator top view;
Fig. 3 is ceramics insulator cutaway view;
Fig. 4 is metal shell top view;
Fig. 5 is metal shell cutaway view.
The specific embodiment
Below in conjunction with Fig. 1 to Fig. 5, illustrate the embodiment 1 of lamp holder of the present invention, it comprises the ceramics insulator 2 of tubular, and described ceramics insulator upper end connects the metal shell 3 of a hollow, and described ceramics insulator lower end connects a glass head 1.
