Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable alignment technology, and in particular to a cable alignment instrument. Background Technology
[0002] The field of line alignment equipment primarily focuses on developing devices capable of quickly and accurately identifying the two ends of conductors, finding wide application in numerous fields such as power engineering, communication engineering, and automation control. Whether in the electrical wiring of new buildings, the laying of communication lines, or the maintenance and repair of older lines, line alignment equipment plays a crucial role. Its ability to accurately locate the two ends of conductors greatly improves the efficiency of line construction and maintenance, ensuring the normal operation of various line systems.
[0003] Traditional cable calibration instruments typically integrate the connectors into the main body. During calibration, both ends of the cable to be calibrated must be connected to the main and slave terminals respectively. The main unit sends a specific electrical signal, which the slave unit receives and identifies to determine the correspondence between the two ends of the cable. This method is relatively effective when the cables are relatively regularly distributed, closely spaced, and arranged in a straight line.
[0004] Traditional cable calibration instruments are unable to complete measurements effectively in a single operation when cables are far apart or arranged in a dispersed manner. Because their connectors are integrated into the main housing, wire connections are subject to significant space constraints, making it difficult to adapt flexibly to complex wiring environments. This results in low calibration efficiency and may even affect the accuracy of calibration results due to inaccurate wire connections, increasing the difficulty and cost of line construction and maintenance.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0027] The field of line alignment equipment primarily focuses on developing devices capable of quickly and accurately identifying the two ends of conductors, finding wide application in numerous fields such as power engineering, communication engineering, and automation control. Whether in the electrical wiring of new buildings, the laying of communication lines, or the maintenance and repair of older lines, line alignment equipment plays a crucial role. Its ability to accurately locate the two ends of conductors greatly improves the efficiency of line construction and maintenance, ensuring the normal operation of various line systems.
[0028] Traditional cable calibration instruments typically integrate the connectors into the main body. During calibration, both ends of the cable to be calibrated must be connected to the main and slave terminals respectively. The main unit sends a specific electrical signal, which the slave unit receives and identifies to determine the correspondence between the two ends of the cable. This method is relatively effective when the cables are relatively regularly distributed, closely spaced, and arranged in a straight line.
[0029] Traditional cable calibration instruments are unable to complete measurements effectively in a single operation when cables are far apart or arranged in a dispersed manner. Because their connectors are integrated into the main housing, wire connections are subject to significant space constraints, making it difficult to adapt flexibly to complex wiring environments. This results in low calibration efficiency and may even affect the accuracy of calibration results due to inaccurate wire connections, increasing the difficulty and cost of line construction and maintenance.
[0030] To resolve the above technical issues, please refer to Figures 1 to 4 This application provides a cable calibration device, which may include a host 1 and a slave 2. The host 1 is used to connect to one end of the cable, and the slave 2 is used to connect to the other end of the cable.
[0031] Please continue reading for more details. Figure 1 and Figure 2 The main unit 1 may include a housing, a connector assembly, and a take-up device.
[0032] Specifically, the outer shell is rectangular in shape, defining a receiving cavity. The outer shell includes a first sidewall and a second sidewall. The first sidewall can be the front sidewall of the outer shell, and the second sidewall can be the upper sidewall of the outer shell. The first sidewall is provided with a storage opening 3, which penetrates the first sidewall and communicates with the receiving cavity. The cross-section of the storage opening 3 is rectangular, and the length direction of the storage opening 3 is consistent with the left and right direction of the outer shell. The second sidewall is provided with multiple first indicator lights 9.
[0033] The connector assembly is detachably located at the storage opening 3. The connector assembly includes multiple connectors 4 arranged side by side in the left-right direction. Adjacent connectors 4 are detachably connected. Multiple connectors 4 correspond one-to-one with multiple first indicator lights 9. That is, the number of connectors 4 is the same as the number of first indicator lights 9, and one first indicator light 9 corresponds to one connector 4.
[0034] Please continue reading. Figure 2 and Figure 3 The take-up device may include a bracket 10, a spool 11 and an extension wire 6. The bracket 10 is mounted on the inner wall of the receiving cavity. Specifically, the bracket 10 is mounted on the bottom wall of the receiving cavity. The bracket 10 is formed as a vertical rod. The spool 11 is rotatably connected to the upper end of the bracket 10. The extension direction of the spool 11 is parallel to the bottom wall.
[0035] The extension wire 6 is wound on the spool 11. One end of the extension wire 6 is electrically connected to the spool 11, and the other end is electrically connected to the connector 4. Multiple take-up devices correspond one-to-one with multiple first indicator lights 9. That is, the number of take-up devices is the same as the number of first indicator lights 9. One first indicator light 9 corresponds to one take-up device. The spool 11 is electrically connected to the first indicator lights 9.
[0036] The slave unit 2 is equipped with multiple second indicator lights, which correspond one-to-one with multiple first indicator lights 9. That is, the number of second indicator lights is the same as the number of first indicator lights 9, and one first indicator light 9 corresponds to one second indicator light. The slave unit 2 is also equipped with multiple slave connectors 4, which are the same as the number of second indicator lights, and one slave connector 4 corresponds to one second indicator light.
[0037] The first indicator light 9, the spool 11, the extension wire 6 and the connector 4 are electrically connected in sequence. The connector 4 is electrically connected to the slave connector 4 on the slave unit 2 via a cable. Then the slave connector 4 is electrically connected to the second indicator light. The two ends of the same cable are determined by the illumination of the first indicator light 9 and the second indicator light.
[0038] In this way, when the cables are arranged in a dispersed manner, that is, when the ends of the cables are at different positions, the connector 4 in the host 1 can be removed, and then the connector 4 can be pulled out of the receiving cavity. By pulling out the extension wire 6 at different lengths, the connection of the cable ends at different positions can be achieved. This allows the cable calibration device to flexibly adapt to complex wiring environments, improve the efficiency of cable calibration, and reduce the difficulty and cost of line construction and maintenance.
[0039] In some embodiments of this application, please refer to Figure 4 The connector 4 includes a connector housing, a movable locking block 17, a main rod 18, and a return spring 19. The connector housing defines a connector groove with a front opening. The front opening faces the same direction as the receiving opening 3. The connector housing includes a first wire-locking wall and a second wire-locking wall. The first wire-locking wall and the second wire-locking wall are arranged opposite each other in the parallel direction of the multiple connectors 4. The first wire-locking wall is provided with a first through hole, and the second wire-locking wall is provided with a second through hole 20.
[0040] The movable locking block 17 is located between the first and second wire-locking walls and can move between them; one end of the main rod 18 is connected to the movable locking block 17, and the other end extends out of the wiring housing through the first through hole. The diameter of the second through hole 20 is larger than the diameter of the main rod 18. The second through hole 20 is used for the insertion of the main rod 18 of the adjacent wiring head 4; the return spring 19 is clamped between the first wire-locking wall and the movable locking block 17. The return spring 19 always applies a force toward the second wire-locking wall to the movable locking block 17.
[0041] Therefore, by pulling the main rod 18, the moving block 17 can be moved from the second clamping wall to the first clamping wall, and by setting the reset spring 19, the moving block 17 can be moved from the first clamping wall to the second clamping wall.
[0042] One end of the cable is inserted between the movable clamp 17 and the second clamp wall. By setting a movable clamp that can move between the first clamp wall and the second clamp wall, the connection of the connector 4 pairs of cables with different diameters can be realized, further improving the versatility of the cable calibration device.
[0043] It should be noted that, taking the connected connectors 4 as connector one and connector two as an example, the second wire clamping wall of connector one is adjacent to the first wire clamping wall of connector two, and the protruding part of the main rod 18 of connector two extends into the second through hole 20 of connector one, so as to realize the detachable connection between adjacent connectors 4.
[0044] In some embodiments of this application, a fixed locking block 16 is provided on the inner surface of the second locking wire wall; a mating notch is provided on the side surface of the movable locking block 17 facing the second locking wire wall, and the fixed locking block 16 is disposed opposite to the mating notch.
[0045] Therefore, by setting the fixed card block 16 and the matching notch, the wire clamping structure of the card tooth structure is realized, thereby ensuring the stability of the cable clamping.
[0046] Furthermore, there are multiple fixed locking blocks 16, which are spaced apart in the depth direction of the wiring groove; there are multiple mating notches, which correspond one-to-one with the multiple fixed locking blocks 16.
[0047] In this way, the multiple locking blocks 16 and the multiple mating notches further achieve the effect of fixing the cable, ensuring the electrical connection effect of the connector 4 to the cable end.
[0048] Furthermore, in the specific implementation process, the surface of the moving block 17 facing the fixed block 16 can be an arc-shaped surface.
[0049] Alternatively, the surface of the fixed card block 16 facing the moving card block 17 can be an arc-shaped surface.
[0050] Alternatively, the surface of the movable card block 17 facing the fixed card block 16 can be an arc-shaped surface, while the surface of the fixed card block 16 facing the movable card block 17 can also be an arc-shaped surface.
[0051] It should be noted that the cable is generally cylindrical. By setting the surface of the moving block 17 facing the fixed block 16 as an arc surface and the surface of the fixed block 16 facing the moving block 17 as an arc surface, the contact area between the fixed block 16, the moving block 17 and the cable can be increased, further ensuring the connection stability of the connector 4 to the cable.
[0052] Please refer to some embodiments of this application. Figure 4The return spring 19 is sleeved on the outer circumference of the main rod 18. This prevents the return spring 19 from wobbling between the first clamping wall and the moving clamping block 17, ensuring the overall stability of the connector 4 structure.
[0053] Furthermore, a spring engagement groove is provided on the first card wall, with the opening of the spring engagement groove facing the moving card block 17. The first through hole penetrates the bottom wall of the spring engagement groove. The reset spring 19 is sleeved on the main rod 18 around the outside and passes through the inner wall of the spring engagement groove.
[0054] This further ensures the stability of the position of the reset spring 19 and the overall stability of the connector 4 structure.
[0055] Please refer to some embodiments of this application. Figure 1 The main unit 1 also includes a sponge pad 21, which is sandwiched between the connector group and the inner wall of the storage opening 3 in the arrangement direction of the multiple connectors 4.
[0056] In this way, by setting the elastic sponge pad 21, an interference fit can be achieved between the connector assembly, the sponge pad 21 and the storage opening 3, and a detachable connection can be achieved between the connector assembly and the storage opening 3. At the same time, when it is necessary to disassemble and remove one or more connectors 4 in the connector assembly, the sponge pad 21 can be squeezed to create a gap between the connected connectors 4, so that the main rod 18 in the connector 4 can be disengaged from the second through hole 20 of the adjacent connector 4, thereby achieving the function of separating the adjacent connectors 4.
[0057] It can be understood that the deformation thickness of the sponge pad 21 is greater than the length of the main rod 18 extending out. The deformation thickness refers to the difference between the natural thickness of the sponge pad 21 and the minimum thickness that is compressed.
[0058] In some embodiments of this application, please refer to Figure 2 The calibration device also includes a circuit control module 8, which is connected in series between the first indicator light 9 and the spool 11.
[0059] Specifically, a motherboard substrate 7 is provided inside the receiving cavity, and a circuit control module 8 is mounted on the motherboard substrate 7. The spool 11 and the motherboard substrate 7 are electrically connected through a connecting wire 15, that is, the motherboard substrate 77 is electrically connected to the connector 4 through the connecting wire 15, the spool 11, the extension wire 6, and the connector 4.
[0060] In operation, different electrical signals are sent via the circuit control module 8. These signals are transmitted to the connector 4 via the connecting wire 15, spool 11, and extension wire 6. The signals then pass through the wire to be tested and connect to the slave unit 2. After being received by the corresponding circuit control module on the slave unit 2, the corresponding second indicator light is activated. Specifically, one end of a cable is plugged into position one on the master unit 1, and the other end is plugged into position three on the slave unit 2. When the same signal is detected by the circuit control module 8, the first indicator light 9 at position one on the master unit 1 and the second indicator light at position three on the slave unit 2 illuminate, completing the verification.
[0061] Please refer to some embodiments of this application. Figure 2 and Figure 3 The cable alignment device may also include a cable management shell 14, which is located inside the receiving cavity and between the cable take-up device and the connector 4. The extension wire 6 passes through the cable management shell 14 and is electrically connected to the connector 4.
[0062] Specifically, the cable management shell 14 is formed as an inverted U-shaped support 10 and is mounted on the bottom wall of the receiving cavity. The upper crossbar of the cable management shell 14 is provided with a cable passage hole, through which the extension wire 6 passes. This reduces the exposed length of the extension wire 6 in the receiving cavity, reduces redundancy, and ensures the internal stability of the structure.
[0063] The extension wire 6 can be set as a flat wire bundle, and the copper wire hole can be set as a rectangular hole, which can reduce the shaking of the wire in the cable management shell 14.
[0064] Please refer to some embodiments of this application. Figure 2 and Figure 3 The take-up device may also include a take-up reel 5, with a spool 11 passing through it. The portion of the extension wire 6 wound around the spool 11 is housed within the take-up reel 5. The take-up reel 5 is provided with a side plate 12 and a spring 13. One end of the spring 13 is connected to the spool 11, and the other end is connected to the side plate 12.
[0065] In this way, when the connector 4 is finished using, or when the connector 4 needs to be returned to the storage opening 3, the operator only needs to release the connector 4. Under the action of the spring 13, the connector 4 will be pulled to the storage opening 3 by the extension wire 6. The operator can then put the connector 4 back in place, which saves operation time and is simple to operate.
[0066] It can be understood that a battery 22 is also installed in the cavity to provide power to the electrical components on the host 1.
