Abstract

(57) [Summary] [Purpose] The purpose is to provide a light bulb with an insulating holder that performs the same function as a light bulb with a socket attached to the light bulb itself, which is mainly used for lighting the inside of a refrigerator. [Structure] The present invention is a light bulb with an insulating holder having the following structure. The end of the light emitting body protruding outside the bulb is connected to the tab terminal. The area from the rear of the bulb to the tab terminal is covered with an insulating material by injection molding, leaving the tab terminal end on the electrode side.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is designed to attach a socket to the light bulb itself, which is mainly used for lighting inside refrigerators. Concerning light bulbs with a holder made of insulating material that performs the same function as the one in which they are attached. It is.

0002

[Conventional technology]

Traditionally, light bulbs and sockets were manufactured separately. In other words, to manufacture light bulbs Insert the light emitter into the bulb so that the end protrudes outside the bulb, and then While creating a vacuum, a cap made in a separate process was attached. Also, the socket should be The main body with a hole in the center for attaching the receiving bracket is manufactured by injection molding. was manufactured separately. The receiving metal fittings can be drawn, deep drawn, threaded, drilled, cut, or shaped. It was manufactured through multiple steps: nailing, plating, press-fitting the bottom plate, and tightening the bottom plate. stop Then, the receiving metal fitting was press-fitted into the cavity for mounting the main body, and finally the bottom plate was wired.

0003

[Problem that this invention attempts to solve]

In conventional technology, socket manufacturing, especially receiving metal fitting manufacturing, involves multiple steps. Ta. This has led to the development of devices that are easy to manufacture and can replace sockets in functionality. It was wanted.

0004 Therefore, the present invention was developed by attaching an insulating material to the unfinished light bulb itself to maintain insulation. It is possible to achieve the same effect as putting a light bulb in a socket without using the body. The present invention provides a light bulb with an insulating holder.

[0005]

[Technical means to solve the problem]

In order to solve the above problem, it is necessary to place the light emitter inside the bulb and place the end of the light emitter outside the bulb. Insert the valve so that it protrudes, create a vacuum inside the valve, seal the rear part of the valve, and remove it from the outside of the valve. Connect the protruding end of the light emitting body to the tab terminal, and connect the end of the bulb to the tab terminal. An insulating holder made by injection molding and covering the tab terminal end on the electrode side with an insulating material. An attached light bulb was constructed.

[0006] Furthermore, we have provided unevenness at the rear of the valve to prevent rotation, and in addition, we have replaced the insulator with flexible material. By using it as a material, the degree of product completion can be increased.

[0007]

【Example】

Examples of the present invention will be described below. Figure 4 shows one of the insulator-equipped light bulbs according to the present invention. FIG. 3 is a side sectional view showing the embodiment, and FIG. 3 shows the light bulb part and tab terminal in the embodiment. FIG.

[0008] 1 in the figure is a bulb made of a transparent material such as glass, and inside the bulb 1 A light emitter 2 is arranged. The light emitting body 2 has a light emitting body end 3 protruding outside the bulb 1. It has been inserted so that The bulb 1 shown in Figures 1 to 4 is for normal lighting. It is the same as a light bulb.

[0009] The manufacturing process begins by creating a vacuum inside the valve 1, and then opening the rear part 4 of the valve 1 on both sides. The pressure is gradually narrowed down, and when the inside of the bulb 1 becomes a vacuum, the rear part 4 of the bulb emits light. The body end 3 is sealed in a state protruding outside the valve 1.

0010 A light emitter end 3 protruding outside the bulb 1 is connected to a tab terminal 5. How to connect Possible methods include soldering and caulking. 9 in the figure is the soldering part It's a minute.

[0011] After the bulb body is manufactured by the above process, from the rear part 4 of the bulb 1 to the tab terminal 5 is covered with an insulating material 7 by injection molding, leaving the tab terminal end 6 on the electrode side. this As the insulating material 7 in this case, a flexible material such as vinyl chloride resin is used.

0012 In addition, in the sealing process of the valve 1, the part of the rear part 4 of the valve covered with the insulating material 7 It is preferable to provide irregularities 8 for preventing rotation. Figures 5 and 6 are anti-rotation FIG. 4 is a side view and a bottom view of the bulb 1 on which unevenness 8 is formed; The unevenness 8 for preventing rotation is provided by providing flat portions at the locations.

[0013]

【effect】

With the above configuration, the present invention has the following effects. Instead of manufacturing sockets, tab terminals are added from the back of bulb 1 during the bulb manufacturing process. Steps up to 5 include the step of injection molding the insulating material 7, leaving the tab terminal end 6 on the electrode side. By simply inserting a light bulb into a socket, you can achieve the same effect as when a light bulb is inserted into a socket. Compared to manufacturing the socket and socket separately, costs can be reduced significantly. Compared to the manufacturing process of the light bulb itself, there is no need to manufacture or attach a cap. This made it possible to reduce manufacturing costs.

[0014] In the sealing process of the valve 1, the part covered with the insulating material 7 of the rear part 4 of the valve is If unevenness is provided to prevent rotation, the insulating material will adhere more reliably.
