In general, the molding porcelain light bulb socket 100 is integrally formed with a porcelain body 170 composed of a power line connector 300 introducing a power line 310 connected to an external power source and an outer surface of the porcelain body 170. It is composed of the configured socket body (110). The molding porcelain light bulb socket 100 uses a mold resin such as polyester to form a porcelain body 170 having a socket terminal 120 and a screw frame 130 therein, and a power line 310 After connecting to the socket terminal 120 and the screw frame 130, parts such as the power line 310, the body 170, the socket terminal 120 and the screw frame 130 are filled in rubber and molded, that is, It refers to a light bulb socket molded with an insert.

The molding porcelain light bulb socket 100 is a power line connector that connects the socket terminal 120 and the screw frame 130 to the outside of the porcelain socket 170 and the power line 310 to the socket body 110. A portion of the 300 is formed with an insulating waterproof cover made of rubber, that is, the socket body 110 and the porcelain socket 170 integrally molded to form the power line 310, the porcelain socket 170, the socket body 110 and the socket. Since the terminal 120 and the screw frame 130 are closely coupled as a single body, there is no gap or air gap between the power line 310 and the socket body 110, so rainwater does not flow in and the power line 310 and the power line connector 300, the socket body 100, and the porcelain body 170 are physically firmly reinforced and the molded porcelain bulb socket 100 in which the bulb 220 is coupled is hung by the power line 310, the light bulb ( 220) and the molded porcelain bulb socket 100, etc., there is no fear that the power line 310 will be relaxed or separated from the molded porcelain bulb socket 100, and it can be used outdoors and is heated by the porcelain body 170 It is a waterproof molded light bulb socket that can use heat bulbs that generate a lot.

The ceramic body 170 is composed of an insulator made of ceramic, which is an insulator, and the lower end is open so that the light bulb 200 can be inserted and coupled, and the open inner side forms a receiving space where the light bulb 200 is coupled.

That is, the socket body 110 is configured to embrace the entirety of the ceramic body 170 except for the open portion.

When the porcelain body 170 and the socket body 110 are integrally molded, the bottom of the opened porcelain body 170 and the socket body 110 has a longer socket body 110 than the length of the porcelain body (170). The relatively short and open bottom forms a step, which is low in height due to the difference in length between the socket body 170 and the socket body 110 when going from the outside to the center of the socket body 110. The base is formed as a step, that is, a staircase going down in a downward direction so that the screw terminal portion 210 of the light bulb 200 can be screwed into the receiving space of the porcelain socket 170 of the molding porcelain bulb socket 100. A screw frame 130 made of a round female screw made of metal is formed, in other words, the screw frame 130 is formed on the inner circumferential surface of the socket 170.

A socket terminal 120 partially protrudes from the upper inner surface of the porcelain socket 170 and conducts electricity with the screw frame 130. The screw frame 130 and the socket terminal 120 are not electrically connected to each other. While being configured not to be configured, one power line of the external power source is conductive to the screw frame 130 and the other power line is configured to be conductive to the socket terminal 120. When the light bulb 200 is screwed into the molded porcelain light bulb socket 100, the screw terminal part 210 and the screw frame 130 are conducted, and the bulb terminal part 220 and the socket terminal 120 are conducted, so that the light bulb 200 The light emitter conducts and emits light.

Since the screw diameter of the screw frame 130 of the molded porcelain light bulb socket 100 and the screw terminal portion 210 of the light bulb 200 are standardized, the outer diameter of the screw of the screw frame 130 of any molded porcelain light bulb socket 100 is all It is configured identically, and the outer diameter of the screw of the screw terminal portion 210 of any light bulb 200 is also configured identically. The lighting unit 230 of the light bulb 200 is configured to have a larger diameter than the screw terminal unit 210, and between the lighting unit 230 and the screw terminal unit 210, it extends in a cylindrical shape from the lighting unit 230 and has a screw frame 130 in diameter.

A belt-shaped mounting ring 150 protruding with a diameter slightly smaller than the diameter of the socket body 110 is formed around the outer circumferential surface of the socket body 110. The mounting ring 150 protrudes from the outer circumferential surface of the socket body 110 in a flange shape and may be configured in plurality.

The device body 11 covers and adheres to the outer circumferential surface of the socket body 110 at the lower end of the molded porcelain bulb socket 100 so that the contact area with the molded porcelain bulb socket 100 is increased, and corresponds to the socket body 110, and rubber or It consists of a cylinder made of silicon. Since the socket body 110 is generally formed in a cylindrical shape, the device body 11 also has the same or slightly smaller shape as the socket body 110, but is configured in a slightly smaller size than the size of the socket body 110, and the molding porcelain bulb socket When the harmful substance blocking device 10 of (100) is coupled to the molded porcelain light bulb socket 100, the socket body 110 is located inside the device body 11, and the device body 11 is connected to the socket body 110. While embracing the socket body 110 in close contact, the contact area between the device body 11 and the molding porcelain bulb socket 100, that is, the device body 11 and the socket body 110 increases, and their coupling is strengthened. .

The length of the device body 11 is the length from the bottom surface of the ring ring 160 to the lower end of the socket body 110, and the outer diameter of the ring ring 160 is larger than the outer diameter of the device body 11, which is harmful. When the material blocking device 10 is coupled to the molded ceramic bulb socket 100, the device body 11 is no longer inserted toward the socket terminal 120, that is, upward, by the stop rings 160. The outer diameter of the device body 11 and the outer diameter of the socket body 110 may be identical, or the outer diameter of the device body 11 may be larger than the outer diameter of the socket body 110 .

In this case, the ring ring 160 may or may not be configured, and when the ring ring 160 is not configured, the upper and lower ends of the socket body 110 due to the difference in thickness of the device body 11 The outer diameter step stops the insertion of the device body 11 in the direction of the socket terminal 120 when the harmful substance blocking device 10 is coupled to the molded porcelain bulb socket 100. When the outer diameter of the device body 11 and the outer diameter of the socket body 110 are the same, when the low ring ring 160 is configured, the low ring ring 160 is a harmful substance blocking device 10 to the molding porcelain bulb socket 100 When coupled, it acts to stop the insertion of the device body 11 in the direction of the socket terminal 120, which is about to cross the outer diameter step, in a double manner.

When the outer diameter of the device body 11 is larger than the outer diameter of the socket body 110, the inner diameter of the device body 11 and the outer diameter of the socket body 110 are the same, and in this case, the ring ring 160 It is preferable to be configured, and the width of the ring ring 160 is preferably larger than the thickness of the device body 11. The molded porcelain light bulb socket 100, in which the outer diameter of the upper end of the socket body 110 is smaller than the outer diameter of the lower end, has a low ring ring 160 and the device body 11 is configured to correspond to the outer diameter of the lower end of the socket body 110. .

It is preferable that the width of the mounting ring 150 is 1/2 the width of the device body 11 smaller than the thickness of the device body 11, that is, the difference between the inner diameter and the outer diameter of the device body 11. The mounting ring 150 prevents the device body 11 from being pushed up to the top of the bulb socket 100 per mole when the harmful substance blocking device 10 is coupled to the molding porcelain bulb socket 100, thereby preventing the device body 11 from being pushed up. ) to settle in.

The mounting ring groove 12, which becomes a belt-shaped groove in the centrifugal direction around the inner circumference of the device body 11 and is mounted on the mounting ring 150 of the molding porcelain light bulb socket 110 to strengthen the fixation with the socket body 110 It consists of The mounting circle groove 12 has the same width, thickness and inner diameter as the width, thickness and outer diameter of the mounting circle frame 150, and is configured at a position corresponding to the mounting circle frame 150, which is harmful to the molding porcelain bulb socket 100. When the material blocking device 10 is coupled, that is, when the device body 11 is coupled to the socket body 110, the device body 11 is prevented from moving upward by receiving the mounting ring 150.

An elastic part 14 made of rubber or silicone is formed at the lower part of the device body 11 in a curved cylindrical shape extending integrally and communicating up and down. The elastic part 14 extends to the lower part of the device body 11 and is a stepped part that is in close contact with the end of the porcelain socket 170 and the end of the socket body 110 of the molding porcelain bulb socket 100 around the inner circumferential surface ( 15) and the elastically deformable part 14 extending from the elastic fixing part 14-1 and becoming thinner in the downward direction and expanding in diameter when the light bulb 200 is coupled. -2).

When the stepped portion 15 goes toward the center of the socket body 110, it is formed as a step that lowers in height, so that the elastic fixing portion 14-1 acts toward the center of the socket body 110. Controlled by (170), the elastic fixing part (14-1) is stably maintained at the ends of the socket body (110) and the porcelain socket (170).

The elastic part 14 is in vertical communication, that is, the elastic fixing part 14-1 and the elastic deformation part 14-2 are a curved cylindrical shape in vertical communication, and the device body 11 is also in a straight cylindrical shape in vertical communication, so that harmful substances The blocking device 10 is conducted vertically and is configured in a hollow shape. The elastic part 14 has a diameter smaller toward the middle between the elastic fixing part 14-1 and the elastic deformable part 14-2 at both ends of the elastic fixing part 14-1 and the elastic deformable part 14-2, and has a curved cylindrical shape communicating up and down. It consists of When the elastic part 14 is configured in a curved cylindrical shape communicating up and down, and the light bulb 200 is coupled to the molding porcelain light bulb socket 100, the elastic deformation part 14-2 does not roll up at the end and the diameter is enlarged while molding It adheres to the porcelain light bulb socket 100,

Since the device body 11 and the elastic part 14 are conducted vertically to form a hollow shape and the device body 11 is coupled to the outer diameter of the socket body 110, the harmful substance blocking device 10 is combined Depending on the use environment in the molding porcelain light bulb socket 100, that is, in an environment where the harmful substance blocking device 10 is not required, the harmful substance blocking device 10 is separated from the molding porcelain bulb socket 100 and only the bulb socket 100 is used. can be used

Since the elastically deformable portion 14-2 presses the blocking portion 13, the strength of surface contact of the blocking portion 13 to the shoulder 240 is determined by the elastic deformation portion 14-2 on the outer circumferential surface of the shoulder 240. The effect of preventing the inflow of moisture, dust or methane gas by the blocking part 13 is more reliable than the effect by the elastic deformation part 14-2. The blocking portion 13 is configured to have a thinner thickness from the inner circumferential surface of the elastically deformable portion 14-2 toward the distal end. The blocking part 13 protrudes in a flange shape, that is, a pin ring shape, on the inner circumferential surface of the elastically deformable part 14-2, and is protruded from a fixed end to a free end, that is, from the elastically deformable part 14-2 to the end of the blocking part 13. The thickness is thinner as it goes to, and the cross section of the fixed end is composed of a triangle or a shape similar to a triangle.

The blocking portion 13 is configured to have a thinner thickness toward the free end, so that when the light bulb 200 is coupled to the molding porcelain lamp socket 100, the blocking portion 13 is formed by the screw frame 130 to the molding porcelain lamp socket ( 100), the blocking part 13 is easily pushed up, and the fixed end of the blocking part 13 restores the blocking part 13 to its original position, that is, the restoring force is stronger than the free end, so that the blocking part 13 is moved by the restoring force of the free end. The surface adhesion to the outer circumferential surface of the shoulder 240 becomes stronger. The blocking part 13 is the lower inside of the molding porcelain bulb socket 100, that is, the screw frame 130, by the external action, that is, the expanding force by the shoulder 240 and the restoring force of the elastic deformation part 14-2. It acts as a kind of sealing valve that seals the screw terminal part 240 and prevents moisture, dust or methane gas from entering the lower part of the molded porcelain bulb socket 100.

The blocking part 13 is spaced apart from the first blocking part 13-1 configured adjacent to the elastic fixing part 14-1 and the first blocking part 13-1, and the elastic deformation part 14-2 It consists of a second blocking portion (13-2) configured in the end direction of. The first blocking part 13-1 and the second blocking part 13-2 are formed in the elastic deformation part 14-2 to prevent moisture, dust or methane gas from entering the lower part of the molding socket 100. Inflow prevention is performed twice, so that the inflow of moisture, dust or methane gas is more reliably prevented. When the screwing of the light bulb 200 to the molding porcelain bulb socket 100 configured with the harmful substance blocking device 10 is completed, the first blocking part 13-1 in the shoulder 240 composed of the upper and lower ends is the shoulder 240 is in close contact with the outer circumferential surface of the upper end, and the second blocking portion 13-2 is in close contact with the outer circumferential surface of the lower end of the shoulder 240.

The first blocking part 13-1 is formed on the upper part of the elastic deformation part 14-2, and the distance from the first blocking part 13-1 to the screw terminal part 210 is long, and the second blocking part 13-1 2) is formed in the middle of the elastic deformation part 14-2 and has a distance from the first blocking part 13-1 relative to the distance from the first blocking part 13-1 to the screw terminal part 210 it gets shorter Accordingly, the flange width of the first blocking portion 13-1 is larger than that of the second blocking portion 13-2 to correspond to the distance. When the flange widths of the first blocking part 13-1 and the second blocking part 13-2 become larger than necessary, the free end of the flange of the first blocking part 13-1 is screwed to the frame 130. ) and the gap formed at the bottom of the screw terminal part 240, and the free end of the flange of the second blocking part 13-2 overlaps with the first blocking part 13-1, so that the first blocking part ( 13-1). When the flange widths of the first blocking portion 13-1 and the second blocking portion 13-2 become smaller than necessary, surface contact with the outer circumferential surface of the shoulder 240 becomes small. That is, the flange width of the first blocking part 13-1 is larger than that of the second blocking part 13-2, so that the first blocking part 13-1 and the second blocking part 13-2 ) is applied to the positional difference configured in the elastic deformation part 14-2.

The socket terminal 120 made of a metallic material, the screw terminal 130, the light bulb terminal 220, the screw terminal 210, the light bulb terminal 210, and the extension extending from the light bulb terminal 210 to the lighting unit 230 integrally. The first blocking part 13-1 and the second blocking part 13-2 are in close contact with the non-metallic shoulder 240 formed before the part, so that moisture and dust can enter the inside of the molding ceramic lamp socket after the shoulder 240. Corrosion of the metallic material of the molded porcelain bulb socket 100 is prevented by preventing the inflow of methane gas.
