Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically to a porcelain insulator that can prevent wire breakage. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. There are many types of insulators with different shapes. Although different types of insulators have significant differences in structure and appearance, they are all composed of two main parts: insulating components and connecting hardware.

[0003] According to a public notice (No. CN117038236A) regarding a porcelain insulator that can prevent cable loosening, the above application aligns the positions of the insert and the slot. When the pressure seat is pressed towards the base, the insert slides inside the slot. Due to the cooperation of the first and second oblique cuts, the insert will squeeze the locking pin inside the second square groove and slide outward. The pull plate stretches the first spring. When the second square groove corresponds to the first square groove, the return force of the first spring drives the locking pin to return to its original position through the pull plate. The locking pin is inserted into the first square groove, fixing the position of the insert and connecting the pressure seat and the base to fix the cable. The operation is simple and convenient, improving the stability of the connection between the insulator and the cable.

[0004] However, in actual use, when the cable needs to be replaced or repaired after a long period of use, a lot of time is required for disassembly and replacement, which makes it impossible to quickly connect the cable to the equipment. In view of this, we propose a porcelain insulator that can prevent wire breakage. Utility Model Content

[0005] The purpose of this invention is to provide a porcelain insulator that can prevent wire breakage, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a porcelain insulator capable of preventing wire breakage, comprising an insulator body, a connector fixedly connected to the end of the insulator body, and an installation component provided on the outer surface of the connector, the installation component comprising:

[0007] A mounting ring is fixedly connected to the outer surface of the connector. A mounting component is fixedly connected to the upper surface of the mounting ring. A placement block is fixedly connected to the upper surface of the mounting component. A fixing plate is fixedly connected to the side of the mounting component.

[0008] A limiting component is sleeved on the outer surface of the placement block. A bolt is provided on the upper surface of the limiting component, and a threaded rod is provided on the upper surface of the limiting component. A pressing block is rotatably connected to the end of the threaded rod.

[0009] Preferably, the pressing block is arc-shaped and is disposed inside the limiting member, which allows the pressing block to move within the limiting member.

[0010] Preferably, the threaded rod is positioned at the center of the upper surface of the limiting member, and the end of the threaded rod penetrates the upper surface of the limiting member, which allows the pressing block to move when the threaded rod rotates.

[0011] Preferably, the position of the limiting member corresponds to the position of the fixing plate, and the end of the bolt passes through the limiting member and the fixing plate, so that the bolt can fix the limiting member.

[0012] Preferably, the side of the limiting member is provided with a protective component, the protective component including a slot, the slot being opened on the side of the limiting member, a card being engaged inside the slot, and a protective cover being fixedly connected to the side of the card.

[0013] Preferably, the card is convex, and the size of the card is adapted to the size of the card slot.

[0014] Preferably, the protective cover is arc-shaped, and the size of the protective cover is adapted to the size of the mounting component.

[0015] Compared with the prior art, this utility model provides a porcelain insulator that can prevent wire breakage, which has the following beneficial effects:

[0016] 1. This anti-breakage porcelain insulator allows for quick cable connection to equipment. The cable is connected to the connector, positioned on the outer surface of the placement block. The limiting component is then aligned with the placement block, locking onto its outer surface. A bolt is then inserted through the limiting component and fixing plate to initially limit the cable. Rotating the threaded rod moves the pressing block downwards, bringing it into contact with the cable's outer surface and securing the cable. This allows for rapid cable installation and effectively prevents breakage due to excessive tension on the cable and connector.

[0017] 2. This porcelain insulator, which can prevent wire breakage, allows the threaded rod to be effectively protected from rainwater erosion. After the cable is stopped, the clip is aligned with the slot and inserted into the slot. This allows the protective component to cover the installation component, thereby effectively preventing excessive erosion of the threaded rod by rainwater. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a porcelain insulator that can prevent wire breakage, including an insulator body 1, a connector 2 fixedly connected to the end of the insulator body 1, and an installation component 3 provided on the outer surface of the connector 2. The installation component 3 includes an installation ring 301, an installation piece 302, a placement block 304, a fixing plate 303, a limiting piece 305, a bolt 306, a threaded rod 307, and a pressing block 308.

[0024] In this embodiment of the utility model, the mounting ring 301 is fixedly connected to the outer surface of the connector 2. A mounting member 302 is fixedly connected to the upper surface of the mounting ring 301. A placement block 304 is fixedly connected to the upper surface of the mounting member 302. A fixing plate 303 is fixedly connected to the side of the mounting member 302. A limiting member 305 is sleeved on the outer surface of the placement block 304. The position of the limiting member 305 corresponds to the position of the fixing plate 303. A bolt 306 is provided on the upper surface of the limiting member 305. The end of the bolt 306 penetrates both the limiting member 305 and the fixing plate 303, allowing... Bolt 306 can fix the limiting member 305. The upper surface of the limiting member 305 is provided with a threaded rod 307. The threaded rod 307 is located at the center of the upper surface of the limiting member 305. The end of the threaded rod 307 is provided to penetrate the upper surface of the limiting member 305. This allows the pressing block 308 to move when the threaded rod 307 rotates. The pressing block 308 is rotatably connected to the end of the threaded rod 307. The pressing block 308 is arc-shaped and is located inside the limiting member 305, which allows the pressing block 308 to move inside the limiting member 305.

[0025] Meanwhile, a protective component 4 is provided on the side of the limiting member 305. The protective component 4 includes a slot 401, which is opened on the side of the limiting member 305. A clip 402 is engaged inside the slot 401. The clip 402 is convex and its size is adapted to the size of the slot 401. A protective cover 403 is fixedly connected to the side of the clip 402. The protective cover 403 is arc-shaped and its size is adapted to the size of the mounting member 302. In this way, after the cable is limited, the clip 402 can be aligned with the slot 401 and engaged inside the slot 401. This allows the protective cover 403 to cover the mounting member 302, thereby effectively preventing rainwater from corroding the threaded rod 307 excessively.

[0026] In this invention, during use, the cable is connected to the connector 2, and the cable is positioned on the outer surface of the placement block 304. This aligns the position of the limiting member 305 with the position of the placement block 304, allowing the limiting member 305 to be engaged on the outer surface of the placement block 304. Then, the end of the bolt 306 is passed through the limiting member 305 and the fixing plate 303, which initially limits the cable. Next, the threaded rod 307 is rotated to move the pressing block 308 downward, allowing the pressing block 308 to contact the outer surface of the cable, thereby fixing the cable. This allows for quick cable installation and effectively prevents the cable and connector 2 from being subjected to excessive tension, which could cause the cable to break.

[0027] Furthermore, after the cable is stopped, the clip 402 is aligned with the slot 401 and inserted into the slot 401. This allows the protective cover 403 to cover the mounting part 302, thereby effectively preventing rainwater from excessively corroding the threaded rod 307.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
