Description

Technical Field

[0001] This utility model relates to the field of power signal line technology, specifically a power signal line with multiple adapters. Background Technology

[0002] A power signal cable is a signal cable that transmits power current. During operation, the two ends of the signal cable need to be connected to deliver the current from the power supply to the working components. With the development of industrial technology, signal cables for different purposes need to conform to different industry standards to facilitate standardized production and application. However, existing power signal cables still have certain shortcomings in use, such as:

[0003] The utility model disclosure number CN215418768U discloses a new type of plug speaker power cord. By setting an anti-bending block and a fixing plate, it can prevent the power cord from breaking due to pulling during use, and prevent it from affecting the normal use of other speakers, thus solving the problem of breakage caused by pulling.

[0004] For example, the utility model publication number CN209169566U discloses a power signal cable for agricultural unmanned helicopters. The power signal cable harness is more convenient and faster to connect to the corresponding interface on the agricultural unmanned helicopter. Moreover, the use of silver-plated copper core and glass fiber tube makes the power signal cable harness less prone to damage and has good waterproof performance.

[0005] In the aforementioned document, the power cord in the comparative document only has one power connector at one end, and can only be used with the same type of socket during use, which limits the scope of use of the power cord. In addition, the power connector is directly exposed on the outside of one end of the power cord, which makes it easy for the power connector to be accidentally squeezed, making the power cord unusable. As a result, the protection effect of the power connector of the power cord is limited.

[0006] To address the aforementioned issues, innovative designs are urgently needed based on the existing signal line structure. Utility Model Content

[0007] The purpose of this invention is to provide a power signal cable with multiple adapters to solve the problem mentioned in the background art, which is that the power cable has only one power connector at one end, resulting in a limited range of use and the power connector is easily squeezed by accident, making the power cable difficult to use.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a multi-adapter power signal cable, comprising a plug, a power cord, a mating block, and a connecting block. The power cord is fixedly installed on the left side of the plug, and the mating block is fixedly installed on the left side of the power cord. A connecting block is engaged on the left side of the mating block. A binding block is fixedly installed on the left side of the connecting block via the power cord, and an auxiliary wire is fixedly installed on the left side of the binding block. A connector is fixedly installed at the end of the auxiliary wire away from the binding block. Two sets of binding grooves are provided inside the binding block, and two sets of rotating plates are rotatably installed inside the binding block. Grooves are provided inside the rotating plates. Two sets of moving grooves are provided inside the binding block, and support springs are fixedly installed inside the moving grooves. A moving block is fixedly installed at the end of the support spring away from the moving groove. The end of the moving block away from the moving groove is located inside the mating groove, and the mating groove is located inside the rotating plate.

[0009] Preferably, a fixing block is fixedly installed inside the connecting block, and two sets of metal plates are fixedly installed inside the fixing block. A sliding groove is opened on the outer side of the connecting block, and a slip ring is slidably installed inside the sliding groove. A traction rope is fixedly installed on the inner surface of the slip ring. An installation groove is opened inside the connecting block, and a return spring is fixedly installed inside the installation groove. A locking block is fixedly installed at the end of the return spring away from the installation groove. By moving the connecting block and the docking block, the metal plates can be engaged with the limiting groove, thereby enabling the two ends of the power cord to be electrically connected, thus facilitating the transmission of electricity by the power cord.

[0010] Preferably, the docking block has two sets of limiting grooves inside, and a slot is provided on the outside of the docking block. The docking block and the connecting block are covered with rubber sleeves. The main airbag and the auxiliary airbag are nested on the side of the docking block near the connecting block. A conduit is fixedly installed on the outside of the auxiliary airbag. The main airbag and the auxiliary airbag are connected by the conduit, which allows the gas inside the main airbag and the auxiliary airbag to be transferred to each other, thereby facilitating the sealing between the connecting block and the docking block.

[0011] Preferably, the binding groove, rotating plate, and recess are arranged symmetrically in two sets about the vertical central axis of the binding block, and the recess inside the rotating plate is located in the middle of the rotating plate. The symmetrical arrangement of the binding groove, rotating plate, and recess about the vertical central axis of the binding block facilitates binding the auxiliary line to the outside of the binding block through the binding groove.

[0012] Preferably, the moving block forms a locking structure with the rotating plate through the docking groove, and the moving block forms an elastic structure with the supporting spring and the binding block. The locking structure between the moving block and the rotating plate through the docking groove can limit the rotating plate to that position.

[0013] Preferably, the slip ring forms a sliding structure with the connecting block through the sliding groove, and the slip ring forms a traction structure with the locking block through the traction rope. The traction rope is arranged in four sets at equal angles inside the slip ring. The slip ring forms a sliding structure with the connecting block through the sliding groove, which allows the slip ring to slide on the outside of the connecting block through the sliding groove. During the movement of the slip ring, it will drive the locking block to move by driving the traction rope.

[0014] Preferably, the locking block forms an elastic structure with the connecting block via a return spring, and the return spring is fixedly connected to both the locking block and the connecting block. The lower end of the locking block is inclined when viewed from the front. The locking block forms an elastic structure with the connecting block via the return spring, which can push the locking block to move inside the connecting block.

[0015] Preferably, the card block forms a sliding structure with the connecting block through the mounting groove, and the card block forms an engaging structure with the docking block through the card slot. Furthermore, four sets of card slots are provided at equal angles on the outer side of the docking block. The sliding structure formed by the card block with the connecting block through the mounting groove allows the card block to slide inside the connecting block through the mounting groove.

[0016] Preferably, the main airbag and the auxiliary airbag are connected by a conduit, and both the main airbag and the auxiliary airbag have a ring-shaped structure when viewed from the side. The volume of the main airbag is larger than that of the auxiliary airbag. The larger volume of the main airbag allows some of its own gas to be transported into the interior of the auxiliary airbag through the conduit after the main airbag is compressed. This causes the main airbag and the auxiliary airbag to deform and seal the gap between the docking block and the connecting block, thereby improving the sealing effect between the docking block and the connecting block.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In the process of protecting the connector on the outside of the power signal line of the multi-adapter, after the auxiliary wire is wrapped around the outside of the binding block, the moving block can be separated from the docking groove. Then, the rotating plate can be rotated to place the connector inside the binding block and make the binding wire at one end of the connector inside the groove. At this time, the rotating plate can be rotated to make the moving block re-engage with the docking groove, thus completing the process of wrapping and protecting the connector. By setting three sets of connectors of different models, the application range of the power line can be increased and the protection effect of the power line on the connector can be guaranteed.

[0019] 2. During the docking process between the docking block and the connecting block, the docking block will press against the locking block and cause the locking block to move into the mounting groove. During the movement of the locking block, the return spring will be pressed and the return spring will be contracted. After the locking block moves, it will slide on the outside of the docking block. After the docking block and the connecting block are docked, the locking block will engage with the slot, thereby limiting the docking block and the connecting block to this position. This improves the convenience of internal docking of the power signal line and also improves the safety of docking.

[0020] 3. During the docking process of the connecting block and the power signal line of the multi-adapter, the connecting block and the connecting block will first compress the main airbag. After being compressed, the main airbag will shrink and transmit some of its own gas to the interior of the secondary airbag through the conduit. At this time, the secondary airbag will expand and enlarge. The connecting block and the connecting block will then compress the main airbag and the secondary airbag, thereby sealing the connection between the connecting block and the connecting block. Afterwards, the rubber sleeve is pushed onto the outside of the connecting block and the connecting block, which can further improve the sealing effect between the connecting block and the connecting block.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-9 This utility model provides a technical solution: a multi-adapter power signal cable, including a plug 1, a power cord 2, a docking block 3, a connecting block 4, a rubber sleeve 5, a binding block 6, a binding groove 7, an auxiliary wire 8, a connector 9, a rotating plate 10, a groove 11, a moving groove 12, a support spring 13, a moving block 14, a docking groove 15, a fixing block 16, a metal sheet 17, a sliding groove 18, a slip ring 19, a traction rope 20, a mounting groove 21, a return spring 22, a locking block 23, a limiting groove 24, a locking groove 25, a main airbag 26, a secondary airbag 27, and a conduit 28.

[0033] A power cord 2 is fixedly installed on the left side of the plug 1, and a connecting block 3 is fixedly installed on the left side of the power cord 2. A connecting block 4 is snapped onto the left side of the connecting block 3. A binding block 6 is fixedly installed on the left side of the connecting block 4 via the power cord 2, and an auxiliary wire 8 is fixedly installed on the left side of the binding block 6. A connector 9 is fixedly installed at the end of the auxiliary wire 8 away from the binding block 6. Two binding grooves 7 are formed inside the binding block 6, and two rotating plates 10 are rotatably installed inside the binding block 6. A groove 11 is formed inside the rotating plate 10. Two moving grooves 12 are formed inside the binding block 6. A support spring 13 is fixedly installed inside the rotating plate 10, and a moving block 14 is fixedly installed at the end of the support spring 13 away from the moving groove 12. The end of the moving block 14 away from the moving groove 12 is located inside the docking groove 15, and the docking groove 15 is opened inside the rotating plate 10. Two sets of binding grooves 7, rotating plate 10 and grooves 11 are symmetrically arranged about the vertical central axis of the binding block 6. The groove 11 inside the rotating plate 10 is located in the middle position of the rotating plate 10. The moving block 14 forms a locking structure with the rotating plate 10 through the docking groove 15, and the moving block 14 forms an elastic structure with the binding block 6 through the support spring 13.

[0034] according to Figure 1-4 When using the multi-adapter power signal cable, first place the power signal cable at the desired working position. During this process, the user needs to align connector 9 with the desired installation location. After aligning connector 9, the remaining two sets of connectors 9 need to be stored away. During this process, the user sequentially wraps the two sets of auxiliary wires 8 around the outside of the binding block 6, ensuring the auxiliary wires 8 are inside the binding groove 7. After the auxiliary wires 8 are wrapped, the user pushes the moving block 14 to slide inside the moving groove 12. During this movement, the supporting spring 13 is compressed and contracts, causing the moving block 14 to move away from the docking groove 15. After the moving block 14 separates from the docking groove 15, the rotating plate 1 can be rotated. After the rotating plate 10 rotates, a set of connectors 9 can be placed inside the binding block 6. Then, the rotating plate 10 is rotated to reset it. After the connector 9 is inside the binding block 6, the auxiliary wire 8 connected to the connector 9 is located inside the groove 11. The moving block 14 and the docking groove 15 need to be re-engaged. At this time, the rotating plate 10 can be limited inside the binding block 6. After the two sets of connectors 9 are successively limited inside the binding block 6, the plug 1 can be connected and installed with the socket. At this time, the power signal line can be powered on. By setting three sets of connectors 9 of different models, not only is the application range of the power line improved, but the protection effect of the power signal line on the connectors 9 is also improved, thereby avoiding damage to the connectors 9 caused by accidental squeezing.

[0035] A fixing block 16 is fixedly installed inside the connecting block 4, and two sets of metal plates 17 are fixedly installed inside the fixing block 16. A sliding groove 18 is provided on the outer side of the connecting block 4, and a slip ring 19 is slidably installed inside the sliding groove 18. A traction rope 20 is fixedly installed on the inner surface of the slip ring 19. An installation groove 21 is provided inside the connecting block 4, and a return spring 22 is fixedly installed inside the installation groove 21. A locking block 23 is fixedly installed at the end of the return spring 22 away from the installation groove 21. The slip ring 19 forms a sliding structure with the connecting block 4 through the sliding groove 18. The slip ring 19 forms a traction structure with the traction rope 20 and the locking block 23. The traction rope 20 is arranged in four sets at equal angles inside the slip ring 19. The locking block 23 forms an elastic structure with the connecting block 4 through the return spring 22. The return spring 22 is fixedly connected to the locking block 23 and the connecting block 4 respectively. The lower end of the locking block 23 is inclined when viewed from the front. The locking block 23 forms a sliding structure with the connecting block 4 through the mounting groove 21. The locking block 23 forms a locking structure with the docking block 3 through the locking groove 25. The locking groove 25 is arranged in four sets at equal angles on the outside of the docking block 3.

[0036] according to Figure 1-8During the docking installation of the docking block 3 and connecting block 4 inside the power signal line, the fixing block 16 needs to engage with the docking block 3 first. This engagement causes the metal piece 17 to engage with the limiting groove 24. Meanwhile, the connecting block 4 moves towards the docking block 3, causing the locking block 23 to move and contact the docking block 3. After contact, the docking block 3 presses against the locking block 23, causing it to move towards the mounting groove 21. The internal movement occurs, and during the movement of the locking block 23, it compresses and contracts the return spring 22. Meanwhile, the connecting block 4 continues to move, and the locking block 23 moves into the mounting groove 21. Afterward, the locking block 23 slides outside the mating block 3. Once the mating block 3 and connecting block 4 are engaged, the compressed return spring 22 expands and pushes the locking block 23. During this movement, the locking block 23 enters the locking groove 25, thus limiting the mating block 3 within the connecting block 4. At this point, the metal... The metal plate 17 and the limiting groove 24 are tightly engaged. Then, the user places the soft rubber sleeve 5 on the outside of the mating block 3 and the connecting block 4. This completes the installation and connection process between the power signal lines. To separate the mating block 3 and the connecting block 4, the user pushes the rubber sleeve 5 to slide it on the outside of the connecting block 4 and separate it from the connecting block 4. The user can then push the slip ring 19 to move inside the slide groove 18. During the movement of the slip ring 19, the traction rope 20 drives the locking block 23 to move. The movement of the locking block 23... The middle block moves away from the slot 25 and into the mounting slot 21. After the middle block and the slot 25 move away from the middle block, the mating block 3 and the connecting block 4 can be separated. During the separation of the mating block 3 and the connecting block 4, the metal piece 17 will separate from the limiting groove 24. At this time, the internal docking process of the power signal line is completed. By locking the mating block 3 and the connecting block 4, the work of stripping wire and wrapping insulating tape is avoided during the internal docking of the power signal line. This improves the convenience of internal docking of the power signal line and also improves the safety of docking.

[0037] The docking block 3 has two sets of limiting grooves 24 inside, and a slot 25 is provided on the outside of the docking block 3. The docking block 3 and the connecting block 4 are fitted with rubber sleeves 5. The main airbag 26 and the auxiliary airbag 27 are nested on the side of the docking block 3 near the connecting block 4. The auxiliary airbag 27 is fixedly installed with a conduit 28 on the outside. The main airbag 26 and the auxiliary airbag 27 are connected through the conduit 28. The main airbag 26 and the auxiliary airbag 27 are both annular structures when viewed from the side. The volume of the main airbag 26 is larger than that of the auxiliary airbag 27.

[0038] according to Figure 1-2, Figure 5 and Figure 9 During the docking process between docking block 3 and connecting block 4, the connecting block 4 will preferentially contact the main airbag 26 during its movement. Upon contact with the connecting block 4, the main airbag 26 will be compressed, causing it to contract. During this contraction, some of the gas from the main airbag 26 will be transferred through the conduit 28 to the interior of the auxiliary airbag 27, which will then expand. When the connecting block 4 and docking block 3 are fully engaged, the connecting block 4 will stop moving. At this point, the connecting block 4 and docking block 3 will... The main airbag 26 and the auxiliary airbag 27 are compressed. After being compressed, the main airbag 26 and the auxiliary airbag 27 will deform and fill the gap between the connecting block 4 and the mating block 3, thereby effectively improving the sealing effect between the mating block 3 and the connecting block 4. After the mating block 3 and the connecting block 4 are mated, the user will put the rubber sleeve 5 on the outside of the mating block 3 and the connecting block 4. The rubber sleeve 5 will be in close contact with the mating block 3 and the connecting block 4, thereby further improving the sealing performance between the mating block 3 and the connecting block 4 and increasing the overall practicality.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
