Description

Technical Field

[0001] This utility model relates to the field of gas pipe connector technology, and in particular to an insulating connector with leakage current indication function. Background Technology

[0002] In gas transmission pipeline systems, insulating joints are one of the key components ensuring the safe operation of the pipeline. Their main function is to isolate the electrical connection between different parts of the pipeline, prevent damage to pipeline connection equipment caused by factors such as leakage, static electricity accumulation, and lightning, prevent the risk of electrolytic corrosion or ignition, and ensure the safety and stability of the gas transmission process.

[0003] In addition to basic insulation properties, insulating connectors with warning functions have appeared on the market, such as... Figure 1 As shown, this type of connector can issue an alarm to the user via an indicator light when abnormal conditions such as static electricity or leakage occur, so that timely safety protection measures can be taken to avoid potential safety accidents.

[0004] However, this type of insulating connector still has the following drawbacks in use:

[0005] 1. Indicator lights are usually installed on one side, and are easily blocked after installation, resulting in poor visibility;

[0006] 2. Most circuit boards are front-mounted and lack side-mounted waterproof design, making them susceptible to moisture damage;

[0007] 3. The prompt module occupies the external hexagonal mounting position, affecting tool clamping and making installation and maintenance inconvenient. Utility Model Content

[0008] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an insulating connector with advantages such as full-circumference light indication, waterproof insertion, and interference-free installation, which significantly improves the product's visibility, sealing performance, and ease of operation.

[0009] An insulating connector includes a connector body made of insulating material. The connector body has a through hole extending through both ends. Each end of the through hole has a connector for connecting a gas pipeline or gas equipment. The connector body includes a rotating part and an assembly part arranged adjacent to each other. The rotating part is used to rotate the connector body by a tool. The assembly part is provided with a prompting device, which is electrically connected to the connectors at both ends.

[0010] The warning device includes a light ring surrounding the assembly part. The light ring is a circular light-emitting structure, and the warning light emitted by it is visible at any circumferential position.

[0011] The beneficial effects of this utility model are:

[0012] By mounting the light ring around the assembly part, the light ring can achieve full-circumference illumination, with no blind spots at any installation angle;

[0013] The assembly section has a side-opening mounting chamber, and the circuit board is inserted from the side and sealed by a waterproof structure to avoid moisture corrosion and improve reliability.

[0014] The part indicator is located entirely on one side of the assembly part, and the rotating part has a complete hexagonal structure without any protrusions or electronic components, which greatly facilitates installation and disassembly. Attached Figure Description

Detailed Implementation

[0022] This utility model provides an insulating joint. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] This embodiment discloses an insulating connector, such as Figure 2-5 As shown, the connector body 1 is made of insulating material, with a through hole 2 in the middle and metal connectors 3 fixed at both ends by fitting grooves 5. The connector body 1 is divided into a rotating part 11 and an assembly part 12. The rotating part 11 is hexagonal in shape for easy gripping with a wrench. The assembly part 12 has a cavity 121 on its side, with its opening facing to the side.

[0025] The prompting device 4 includes a sensing circuit board 41, two conductive plates 42, and a lamp ring 43. The circuit board 41 and the conductive plates 42 are disposed within the cavity 121, with one end of the conductive plates 42 contacting the connector 3. The lamp ring 43 is a ring-shaped light-guiding structure, with its abutting part 433 extending into the cavity to contact the light-emitting element 411. The sealing part 432 covers the cavity opening and is welded to the sealing structure 122 via ultrasonic welding to achieve waterproofing.

[0026] The light ring 43 emits light in all directions and is visible from any angle. The circuit board 41 is installed laterally, without occupying space in the rotating part, and does not need to avoid the indicator module during installation, making it easy to operate.

[0027] Furthermore, such as Figure 3 As shown, the two guide plates 42 pass through the inside of the mounting chamber 121 and abut against the connector 3. One end of the lamp ring 43 extends into the mounting chamber 121 from the opening and abuts against the light-emitting element 411 on the circuit board 41. The lamp ring 43 is a light guide plate, which can convert the line light source emitted by the light-emitting element 411 into a surface light source to achieve overall light emission.

[0028] Furthermore, such as Figure 4As shown, the lamp ring 43 includes a surrounding portion 431 that surrounds the assembly portion 12, a sealing portion 432 integrally connected to the surrounding portion 431, and an abutment portion 433 integrally connected to one side of the sealing portion 432. After the lamp ring 43 is installed on the assembly portion 12, the abutment portion 433 is inserted into the mounting chamber 121 and abuts against the light-emitting element 411. Finally, the mounting chamber 121 is sealed by the sealing portion 432. Specifically, the sealing portion 432 of the lamp ring 43 abuts against the end face at the opening of the mounting chamber 121, and then the end face and the sealing portion 432 are fused together by ultrasonic sealing technology to form an integral whole, thereby sealing the mounting chamber 121. In addition, in order to improve the sealing effect, a raised sealing edge structure 122 is provided on the end face at the opening of the mounting chamber 121. The sealing edge structure 122 surrounds the end face of the mounting chamber 121 and can improve the fusion effect during sealing. The ultrasonic sealing technology is existing technology, and the specific usage method and working principle will not be described in detail.

[0029] In this embodiment, the connector body 1 and the connector 3 can be molded together by injection molding to improve the connection stability. In addition, each of the two connectors 3 is provided with a connection structure 6. The connection structure 6 is preferably a threaded structure. Furthermore, the connection structure 6 on the connector 3 near the rotating part 11 is an external thread structure 61, while the connection structure 6 on the connector 3 near the assembly part 12 is an internal thread structure 62.

[0030] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present invention.
