Description

Technical Field

[0001] This utility model relates to the field of cable identification technology, and more specifically, to a signal receiving clamp for a cable identification device. Background Technology

[0002] The cable identifier is a specialized instrument developed to meet the needs of the power industry. It is used in the installation, relocation, maintenance, and fault handling of power cables to identify a specific cable within a cable bundle. It features accurate cable identification (dual identification of direction and amplitude), speed, simple operation, and wide applicability. The cable identifier consists of three parts: a signal generator, a receiving clamp, and an indicator. When the receiving clamp is used as a signal detector, the signal detected on other cables is much weaker and in the opposite direction. By indicating the amplitude and direction on the meter, the cable under test can be easily identified. However, some cables have dust on them, which can accumulate on the receiving clamp during testing, making cleaning difficult. Furthermore, the receiving clamp is not easily secured when placed on the outside of the cable. Therefore, we have proposed a signal receiving clamp for the cable identifier. Utility Model Content

[0003] In view of the problems mentioned in the background art above, the purpose of this utility model is to provide a signal receiving clamp for a cable identification device.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A signal receiving clamp for a cable identifier includes a receiving clamp body with two arc-shaped clamp heads. Spring hinges are fixedly mounted at the bottom ends of the two arc-shaped clamp heads. Multiple support mechanisms are provided on the inner sides of each of the two arc-shaped clamp heads. A handle is fixedly connected to the bottom end of each of the two arc-shaped clamp heads. An installation cylinder is mounted on the side of the bottom end of one of the arc-shaped clamp heads. A blower cover is provided at the end of the installation cylinder. A blower fan is fixedly mounted inside the installation cylinder. A power supply box is fixedly connected to the bottom surface of the installation cylinder. A lithium battery is housed inside the power supply box. A control button is provided on the side of the power supply box. The blower fan is electrically connected to the lithium battery and the control button, respectively.

[0006] As a preferred embodiment of this utility model, the support mechanism includes an L-shaped card seat fixedly connected to the inner side of the arc-shaped clamp head, an arc-shaped card plate sleeved on the inner side of the two L-shaped card seats, an outer support cylinder fixedly connected to the side of the arc-shaped card plate, a support spring fixedly connected to the side of the arc-shaped card plate and located in the inner cavity of the outer support cylinder, a movable plate fixedly connected to the end of the support spring, a telescopic column fixedly connected to the end face of the movable plate, and a rubber block fixedly connected to the end of the telescopic column extending to the outside of the outer support cylinder.

[0007] As a preferred embodiment of this utility model, an internally threaded post is fixedly connected to the side of the bottom end of the arc-shaped pliers head, and a connecting frame is fixedly connected to the other end of the mounting cylinder. A stud is fixedly connected to the connecting frame, and the end of the stud is threaded into the inner cavity of the internally threaded post.

[0008] As a preferred embodiment of this utility model, a charging slot is provided on the side of the power supply box, and a charging socket is provided on the side of the lithium battery, with the charging slot and the charging socket being aligned.

[0009] In a preferred embodiment of this utility model, the top and bottom of the arc-shaped card plate are respectively fitted with the inner sides of the two L-shaped card seats, and the outer side of the arc-shaped card plate is fitted with the inner side of the arc-shaped clamp head.

[0010] In a preferred embodiment of this utility model, the side of the movable plate is in contact with the inner wall of the outer support cylinder.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] (1) In this utility model, an installation cylinder is installed on the side of the receiving clamp body by the cooperation of the internal threaded column and the stud. The fan is started by the control button to make the blower cover blow outward. The air blown out by the blower cover blows the outside of the cable to clean the dust off the outside of the cable, so as to avoid the receiving clamp body from getting dust on the outside of the cable when it is fitted on the outside of the cable, especially to prevent dust from getting on the contact part of the two arc-shaped clamp heads.

[0013] (2) In this utility model, multiple support mechanisms are installed on the inner side of the two arc-shaped clamp heads by the cooperation of the L-shaped clamp seat and the arc-shaped clamp plate. When the two arc-shaped clamp heads are fitted on the outside of the cable, the rubber block on the support mechanism contacts the outside of the cable. At the same time, the telescopic column and the movable plate contract into the inner cavity of the outer support cylinder, causing the support spring to be squeezed. The elastic force of the support spring is used to squeeze the outside of the cable by the movable plate, telescopic column and rubber block, so that the receiving clamp body is stably supported on the outside of the cable by multiple support mechanisms, which is convenient and practical.

[0026] In this embodiment, the blower 6 is controlled by the control button 9 and powered by the lithium battery 8. The blower 6 causes the blower cover 5 at the front of the mounting cylinder 4 to blow air onto the outside of the cable to be tested to clean the dust. The arc-shaped clamp head 2 is equipped with magnets, ribbon cables and other structures inside. This is existing technology and will not be described in detail.

[0027] For details, please refer to Figure 1 , Figure 3 and Figure 4 The support mechanism 10 includes an L-shaped card seat 11 fixedly connected to the inner side of the arc-shaped clamp head 2. An arc-shaped card plate 12 is sleeved on the inner side of the two L-shaped card seats 11. An outer support cylinder 13 is fixedly connected to the side of the arc-shaped card plate 12. A support spring 14 is fixedly connected to the side of the arc-shaped card plate 12 and located in the inner cavity of the outer support cylinder 13. A movable plate 15 is fixedly connected to the end of the support spring 14. A telescopic column 16 is fixedly connected to the end face of the movable plate 15. The end of the telescopic column 16 extends to the outside of the outer support cylinder 13 and is fixedly connected to a rubber block 17.

[0028] For details, please refer to Figure 1 , Figure 2 and Figure 5 An internally threaded post 18 is fixedly connected to the side of the bottom end of an arc-shaped pliers head 2, and a connecting bracket 20 is fixedly connected to the other end of the mounting cylinder 4. A stud 19 is fixedly connected to the connecting bracket 20, and the end of the stud 19 is threaded into the inner cavity of the internally threaded post 18.

[0029] In this embodiment, the mounting cylinder 4 is installed on the side of the receiving clamp body 1 by the cooperation of the internal threaded post 18 and the stud 19.

[0030] For details, please refer to Figure 5 The power supply box 7 has a charging slot 21 on its side and a charging socket 22 on its side. The charging slot 21 and the charging socket 22 are aligned with each other.

[0031] In this embodiment, the charging cable connector of the peripheral device is inserted from the charging slot 21 into the charging socket 22 to charge the lithium battery 8.

[0032] For details, please refer to Figure 1 , Figure 3 and Figure 4 The top and bottom of the arc-shaped card plate 12 are respectively attached to the inner sides of the two L-shaped card seats 11, and the outer side of the arc-shaped card plate 12 is attached to the inner side of the arc-shaped clamp head 2.

[0033] In this embodiment, the stability of the arc-shaped card plate 12 being fitted into the inner cavity of the two L-shaped card seats 11 is ensured, while a certain amount of friction exists between the L-shaped card seats 11 and the arc-shaped card plate 12.

[0034] For details, please refer to Figure 4 The side of the movable plate 15 is in contact with the inner wall of the outer support cylinder 13.

[0035] In this embodiment, the inner wall of the outer support cylinder 13 is used to limit the movable plate 15, so as to ensure the stability of the movable plate 15 sliding in the inner cavity of the outer support cylinder 13.

[0036] Working principle: In use, firstly, the mounting cylinder 4 is installed on the side of the receiving clamp body 1 through the threaded engagement of the internal threaded post 18 and the stud 19. At the same time, multiple support mechanisms 10 are installed on the inner side of the two arc-shaped clamp heads 2 through the engagement of the L-shaped card seat 11 and the arc-shaped card plate 12. Then, the control button 9 is pressed to turn on the blower 6. The blower 6 causes the blower cover 5 at the end of the mounting cylinder 4 to blow air outward. The air force is used to blow the outside of the cable to be tested, thereby cleaning the dust off the outside of the cable. Then, the two handles 23 are pressed to make the two arc-shaped clamp heads 2 rotate around the pivot of the spring hinge 3. This opens the two curved clamp heads 2, allowing them to be clamped onto the outside of the cable. Finally, the pressure of the two handles 23 is released, and the restoring force of the spring hinge 3 causes the two curved clamp heads 2 to close. At this time, the rubber block 17 on the inner side of the curved clamp head 2 contacts the outer side of the cable. Simultaneously, the rubber block 17 is subjected to a certain reverse compressive force, causing the telescopic column 16 and the movable plate 15 to move within the inner cavity of the outer support cylinder 13. The support spring 14 is compressed, thereby using multiple support mechanisms 10 to compress the cable and support the receiving clamp body 1, ensuring the stability of the receiving clamp body 1 mounted on the cable.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
