Description

Technical Field

[0001] This invention relates to the field of cable connection technology, and in particular to an installation device for connecting power cables. Background Technology

[0002] Cables are typically made up of several or more strands of conductors twisted together, resembling a rope. Each strand of conductor is insulated from the others and is often twisted around a central core to form a single cable. The entire cable is covered with a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation, and are used to connect circuits, electrical appliances, and for long-distance power transmission. Due to limitations in manufacturing processes, the length of each cable segment is finite. When the cable length is insufficient for the application requirements, two cables need to be connected together to extend the transmission distance.

[0003] Currently, existing cable connection installation devices (such as patent number: CN109301513B) disclose a contact-reactive cable connection device and method. The connection device includes a thermally conductive connector, a heating mechanism, a fastening mechanism, a sealing sleeve, and a thermoplastic metal block. During connection, the conductive core of the cable is first inserted into the cable connection hole of the thermally conductive connector. Then, the fastening mechanism is adjusted to hold the cable within the cable connection hole. Next, the heating mechanism heats the thermally conductive connector, melting the thermoplastic metal block of a low-melting-point alloy. The molten metal allows for conductivity between the two cables. After the molten metal cools, it strengthens the bond between the conductive core of the cable and the thermally conductive connector, achieving a stable and safe cable connection. The molten metal connection reduces the contact resistance at the cable connection point, ensuring the safe and stable operation of the connected cable.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0005] Poor fixation and prone to loosening: Existing cable connection installation devices require specific connection devices to fix the cable connection to ensure stability. However, existing cables are often fixed by crimping (inserting the cable end into an aluminum tube and then using pliers to deform the tube, thus connecting the two cables). This method not only results in poor fixation of the cable connection but also causes the connection to break when the cable is subjected to external force. This is because the direction of the force on the cable (external force) and the direction of the tension at the cable connection end are on the same centerline, meaning that the external force on the cable acts directly and entirely on the connection end. Therefore, we propose an installation device for power cable connections. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an installation device for power cable connections, solving the technical problems of poor fixing effect and easy loosening of existing cable connection installation devices during use.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] An installation device for power cable connections includes a connection box for protecting the cable connection point and a clamping assembly installed inside the connection box. The clamping assembly clamps the outer sheath of the cable, thereby ensuring the stability of the cable connection. Specifically, the friction between the clamping assembly and the cable counteracts the tensile force (i.e., external force) on the cable.

[0011] The connection box, in the shape of a rectangular box, covers the cable connection point, thereby sealing the cable connection point;

[0012] A clamping assembly is installed inside the connector box and is used to secure the cable sheath.

[0013] The clamping assembly includes a U-shaped support bracket. During use, the cable is inserted into the support bracket, meaning the cable's outer sheath falls into the opening of the support bracket. Two connecting plates are installed at the opening of the support bracket, allowing the inner diameter of the support bracket to be changed by adjusting the distance between the two connecting plates. Figure 2 and Figure 3 As shown, a fixing rod is inserted between the two connecting plates; alternatively, cable ties or clamps or other devices with tightening functions can be used.

[0014] The outer side of the fixing rod is connected to two threaded cylinders via threads, and the threaded cylinders are located on the side where the two connecting plates are opposite to each other. Therefore, rotating the threaded cylinders pushes the connecting plates on the fixing rod towards the center. Thus, by rotating the two threaded cylinders on the fixing rod, the two connecting plates are brought closer together or separated. At this time, the support bracket connected to the connecting plate can reduce or expand the size of the support. Figure 2 and Figure 3 As shown.

[0015] In some examples, the inner wall of the support bracket has multiple anti-slip grooves, and these grooves are arranged along the length of the connecting plate. When the support bracket wraps around the cable, the protective grooves fit tightly against the outer wall of the cable, thereby increasing the friction between the cable and the support bracket.

[0016] In some examples, connecting pipes are installed at both ends of the connection box, and the connecting pipes are used to plug into the cables, so that the cables can be inserted into the connecting pipes to facilitate the entry and exit of the cables into the connection box, and to protect the connection between the cables and the connection box.

[0017] The device consists of two clamping components, each corresponding to a connecting pipe, which clamps and secures both of the interlocking cable ends.

[0018] In some examples, the connection box has an internal mounting plate with multiple connecting posts on top, which facilitates the connection of the cable cores entering the device to the connecting posts, thereby enabling the two cables to be connected (electrically connected).

[0019] The cable end passing through the support bracket is connected to the connecting post. Both cable cores conduct current into the mounting plate through the connecting post, and the two cables are connected together through the mounting plate (electrical connection).

[0020] Preferably, a fixing component is installed on the inner wall of the connecting box, and the fixing component corresponds to the clamping component to fix the cable core. Since the clamping component fixes the cable sheath and the fixing component fixes the cable core, they assist and cooperate with each other to improve the overall fixation of the cable.

[0021] The fixing component includes a connector, inside which a copper plate is installed. A movable plate is movably installed inside the connector, and the movable plate corresponds vertically to the connector. The cable core is partially clamped by the movable plate and the connector, and the cable core can be bent simply by pressing the movable plate. Figures 8 to 9 As shown;

[0022] The connector is hinged to the outside with a cover plate, which covers the top of the connector. The other part of the cable core is clamped by the movable plate and the cover plate, so that the cable core containing the cable can be bent into a "U" shape, like a hook, and can be stably fixed in the connector. Secondly, the structure of this application can be fixed quickly and stably.

[0023] When the cover plate and the connecting seat are engaged, the cable core inside the cable is simultaneously inserted between the movable plate and the copper plate, and between the movable plate and the cover plate. Figure 10 As shown, the cable core is bent into a "U" shape at this time, and both parallel ends of the "U" shape are clamped, thereby transmitting the tension on the cable to the movable plate and the entire fixed assembly.

[0024] The connectors in the two fixed components are connected by wires to electrically connect the two cables entering the junction box.

[0025] In some examples, the movable plate engages with sliding grooves inside the connecting seat via sliders mounted on its sides, and these grooves extend vertically, allowing the movable plate to slide up and down. Figure 8 and Figure 9 As shown;

[0026] The copper plate and the movable plate have corresponding slots on their upper and lower sides. Therefore, when the movable plate is pressed, the cable core is deformed, causing it to tilt upwards. At this time, part of the cable core structure is fixed between the copper plate and the movable plate, forming a... Figure 9 The shape shown.

[0027] In some examples, a prefabricated plate is installed inside the connector, corresponding to the copper plate front and back, and the prefabricated plate is higher than the connector. Therefore, when the movable plate presses down on the cable core, the cable core can be tilted upwards, such as... Figure 9 As shown;

[0028] When the movable plate and the copper plate are bonded together, the top surface of the precast plate and the top surface of the movable plate are on the same horizontal plane, such as... Figure 9 As shown, this allows the cover plate to be stably placed on the movable plate later.

[0029] In some examples, the top of the precast slab has a mating groove, and the mating groove communicates with the slot on the top of the copper plate, such as... Figure 7 As shown, this allows the cable core to easily enter the slot along the mating groove, thus bending the cable core into an "L" shape;

[0030] When the movable plate moves to the top of the chute, the bottom surface of the movable plate is parallel to the top surface of the precast slab, and the mating groove on the top of the precast slab and the retaining groove on the bottom of the movable plate are on the same central axis. At this point, the cable core can be inserted into the mating groove along the retaining groove. Figure 8 As shown, this facilitates pressing up the end of the cable core when the movable plate is pressed down later.

[0031] In some examples, latches are movably mounted on both sides of the cover plate, and the latches are connected to the cover plate by springs, such as... Figure 7 As shown, this causes the locking pin to move away from the cover plate;

[0032] When the cover plate and the movable plate are in contact, the locking pins on both sides of the cover plate are inserted into the slide groove, so that the cover plate is connected to the connecting seat through the interlocking relationship between the locking pins and the slide groove, thereby ensuring the stability of the connection between the cable core and the fixed component.

[0033] In some examples, an iron ring is installed inside the connection box and is connected to the cable core, and two iron rings are connected by a wire;

[0034] The wire between the two iron rings is connected to a wireless transmitter and an indicator light (as well as a voltage regulator). Therefore, when current flows between the two cables, some of the current enters the wireless transmitter and the indicator light, causing the indicator light to light up and the wireless transceiver to send a power-on signal. This makes it easy to determine whether there is current flowing through the cable and whether the cable connection is damaged, thus improving the safety of the device.

[0035] (III) Beneficial Effects

[0036] 1. By using a support bracket to clamp the cable sheath, the technical problems of poor fixation and easy loosening of existing cable connection installation devices are effectively solved. This achieves effective fixation of the cable shell and reduces the impact on the cable, thereby maintaining the stability of the cable fixation.

[0037] 2. Because a fixing component is used to fix the cable core, the technical problem of poor fixing effect and easy loosening of existing cable connection installation devices is effectively solved. Thus, the cable core is effectively fixed. At the same time, by bending the cable core, the connection strength between the cable core and the device can be improved. Attached Figure Description

[0050] This application provides an installation device for power cable connections, solving the technical problems of poor fixing effect and easy loosening of existing cable connection installation devices. By using a support bracket to clamp the cable sheath, the cable outer shell is effectively fixed, and the impact on the cable is reduced, thereby maintaining the stability of the cable fixation. By using a fixing component to fix the cable core, the cable core is effectively fixed, and by bending the cable core, the connection strength between the cable core and the device can be improved.

[0051] Example 1

[0052] The technical solution in this application embodiment effectively solves the technical problem that existing cable connection installation devices have poor fixing effect and are prone to loosening during use. The overall idea is as follows:

[0053] To address the problems existing in the prior art, the present invention provides an installation device for power cable connection. This device includes a connection box 1 for protecting the cable connection point, and a clamping assembly 4 installed inside the connection box 1. The clamping assembly 4 clamps the outer sheath 81 of the cable, thereby ensuring the stability of the cable connection. Specifically, the friction between the clamping assembly 4 and the cable counteracts the tensile force (i.e., external force) on the cable.

[0054] The connecting box 1 (with a cover 2 installed on its exterior) is rectangular and covers the cable connection point to seal it.

[0055] The clamping assembly 4 is installed inside the connecting box 1 and is used to fix the cable sleeve 81.

[0056] The clamping assembly 4 includes a U-shaped support bracket 41. During use, the cable is inserted into the support bracket 41, meaning the cable's outer sheath 81 falls into the opening of the support bracket 41. Two connecting plates 42 are installed at the opening of the support bracket 41, allowing the inner diameter of the support bracket 41 to be changed by adjusting the distance between the two connecting plates 42. Figure 2 and Figure 3 As shown, a fixing rod 43 is inserted between the two connecting plates 42. Alternatively, a cable tie or clamp or other device with a tightening function can be used.

[0057] Two threaded cylinders 44 are threadedly connected to the outer side of the fixing rod 43, and the threaded cylinders 44 are located on the opposite side of the two connecting plates 42. Therefore, when the threaded cylinders 44 are rotated, the connecting plates 42 on the fixing rod 43 can be pushed towards the center. Thus, by rotating the two threaded cylinders 44 on the fixing rod 43, the two connecting plates 42 can be brought closer together or separated. At this time, the support bracket 41 connected to the connecting plate 42 can be used to expand or contract the support. Figure 2 and Figure 3 As shown.

[0058] In some examples, the inner wall of the support bracket 41 is provided with multiple anti-slip grooves 45, and the multiple anti-slip grooves 45 are arranged along the length of the connecting plate 42. When the support bracket 41 wraps around the cable, the anti-slip grooves 45 are tightly fitted to the outer wall of the cable, thereby increasing the friction between the cable and the support bracket 41.

[0059] In some examples, both ends of the connection box 1 are equipped with connection pipes 3, and the connection pipes 3 are used to connect to the cable, so that the cable can be inserted into the connection pipes 3, which facilitates the cable to enter and exit the connection box 1 and protects the connection between the cable and the connection box 1.

[0060] There are two clamping components 4, and each clamping component 4 corresponds to a connecting pipe 3, so as to clamp and fix the two interlocking cable connection ends.

[0061] In some examples, the inside of the connection box 1 is equipped with a mounting plate 5, and the top of the mounting plate 5 is equipped with multiple connecting posts 6, which facilitates the connection of the cable core 82 entering the device with the connecting posts 6, thereby enabling the two cables to be connected (electrically connected).

[0062] The cable end passing through the support bracket 41 is connected to the connecting post 6. Both cable cores 82 conduct current into the mounting plate 5 through the connecting post 6, and the two cables are connected together (electrical connection) through the mounting plate 5.

[0063] In the specific implementation process, the cable that needs to be fixed is inserted from the connecting pipe 3 into the connecting box 1, and the cable core 82 inside the cable is fixed to the connecting post 6. At this time, the cable passing through the connecting pipe 3 falls into the support bracket 41 corresponding to the connecting pipe 3, that is, the outer rubber sleeve 81 of the cable enters the opening of the support bracket 41. Then, the threaded cylinder 44 installed on the fixing rod 43 is rotated, so that it moves along the fixing rod 43 towards the connecting plate 42 under the action of the thread between it and the fixing rod 43, thereby squeezing the connecting plate 42, thereby reducing the opening of the support bracket 41. However, due to the inconvenience of the length of the support bracket 41, the inner diameter of the support bracket 41 decreases during the process of reducing the opening of the support bracket 41. Figures 2 to 3 As shown, this causes the support bracket 41 to squeeze the cable inside, increasing the friction between the two. When the cable is pulled by an external force, there is enough friction to offset the pulling force, thereby clamping and fixing the cable entering and exiting the connection box 1.

[0064] Example 2

[0065] Based on Example 1, the embodiments of this application aim to effectively solve the technical problems of poor fixing effect and easy loosening of existing cable connection installation devices during use. The overall idea is as follows:

[0066] The inner wall of the connecting box 1 is equipped with a fixing component 7, which corresponds to the clamping component 4. It is used to fix the cable core 82 of the cable. Since the clamping component 4 fixes the cable sheath 81, and the fixing component 7 fixes the cable core 82, they assist and cooperate with each other to improve the overall fixation of the cable.

[0067] The fixing component 7 includes a connector 71, and a copper plate 72 is installed inside the connector 71. A movable plate 73 is movably installed inside the connector 71, and the movable plate 73 corresponds vertically to the connector 71. The cable core 82 is partially clamped by the movable plate 73 and the copper plate 72. The cable core 82 can be bent simply by pressing the movable plate 73. Figures 8 to 9 As shown;

[0068] A cover plate 74 is hinged to the outside of the connector 71, and the cover plate 74 covers the top of the connector 71. The other part of the cable core 82 is clamped by the clamping of the movable plate 73 and the cover plate 74, so that the cable core 82 containing the cable can be bent into a "U" shape, like a hook, and can be stably fixed in the copper plate 72. Secondly, through the structure of this application, it is possible to fix quickly and stably.

[0069] When the cover plate 74 and the connecting seat 71 are engaged, the cable core 82 inside the cable is simultaneously inserted between the movable plate 73 and the copper plate 72, and between the movable plate 73 and the cover plate 74. Figure 10As shown, at this time the cable core is bent into a "U" shape, and the two parallel ends of the "U" shape are clamped, thereby transmitting the tension on the cable to the movable plate 73 and the entire fixed component 7.

[0070] The connectors 71 in the two fixing components 7 are connected by wires, thereby electrically connecting the two cables entering the connection box 1.

[0071] In some examples, the movable plate 73 is engaged with a sliding groove inside the connecting seat 71 via sliders mounted on its sides, and the sliding groove extends vertically, thereby allowing the movable plate 73 to slide up and down, such as... Figure 8 and Figure 9 As shown;

[0072] The copper plate 72 and the movable plate 73 have corresponding slots on their upper and lower sides. Therefore, when the movable plate 73 is pressed, the cable core 82 can be deformed, causing it to tilt upwards. At this time, part of the cable core 82 is fixed between the copper plate 72 and the movable plate 73, forming a... Figure 9 The shape shown.

[0073] In some examples, a prefabricated plate 75 is installed inside the connector 71, and the prefabricated plate 75 corresponds to the copper plate 72 front to back. The height of the prefabricated plate 75 is higher than that of the connector 71. Therefore, when the movable plate 73 presses down on the cable core 82, the cable core 82 can be tilted upwards. Figure 9 As shown;

[0074] When the movable plate 73 is attached to the copper plate 72, the top surface of the precast plate 75 and the top surface of the movable plate 73 are on the same horizontal plane, such as... Figure 9 As shown, this allows the cover plate 74 to be stably placed on the movable plate 73.

[0075] In some examples, the top of the precast plate 75 has a mating groove, and the mating groove communicates with the slot on the top of the copper plate 72, such as... Figure 7 As shown, this allows the cable core 82 to enter the slot along the mating groove, thus bending the cable core 82 into an "L" shape;

[0076] When the movable plate 73 moves to the top of the chute, the bottom surface of the movable plate 73 is parallel to the top surface of the precast plate 75, and the mating groove on the top of the precast plate 75 and the slot on the bottom of the movable plate 73 are on the same central axis. At this time, the cable core 82 can be inserted into the mating groove along the slot. Figure 8 As shown, this facilitates pressing up the end of the cable core 82 when the movable plate 73 is pressed down.

[0077] In some examples, latches 76 are movably mounted on both sides of the cover plate 74, and the latches 76 are connected to the cover plate 74 by springs, such as... Figure 7As shown, this causes the locking pin 76 to move away from the cover plate 74;

[0078] When the cover plate 74 is attached to the movable plate 73, the locking pins 76 on both sides of the cover plate 74 are inserted into the slide groove, so that the cover plate 74 is connected to the copper plate 72 through the fastening relationship between the locking pins 76 and the slide groove, thereby ensuring the stability of the connection between the cable core 82 and the fixing component 7.

[0079] In some examples, an iron ring is installed inside the connecting box 1, and the iron ring is connected to the cable core 82, with the two iron rings connected by a wire;

[0080] The wire between the two iron rings is connected to a wireless transmitter and an indicator light (as well as a voltage regulator). Therefore, when current flows between the two cables, some of the current enters the wireless transmitter and the indicator light, causing the indicator light to light up and the wireless transceiver to send a power-on signal. This makes it easy to determine whether there is current flowing through the cable and whether the cable connection is damaged, thus improving the safety of the device.

[0081] In the specific implementation process, the movable board 73 is pulled up to form a shape like... Figure 6 As shown in the diagram, the cable core 82 is then inserted along the slot at the bottom of the movable plate 73 into the mating slot at the top of the precast plate 75, forming a shape as shown. Figure 8 After completing the shape shown, press the movable plate 73, causing it to move downwards and press against the outside of the cable core 82. At this time, the cable core 82 is pressed downwards, and the portion of the cable core 82 extending beyond the movable plate 73 enters the slot along the mating groove. This portion of the cable core 82 is also pressed up, forming a shape as shown. Figure 9 As shown in the diagram, the cover plate 74 is pressed towards the movable plate 73. At this time, the cable core 82 is gradually laid into the arc-shaped groove below the cover plate 74 and pressed between the cover plate 74 and the movable plate 73, forming a shape as shown in the diagram. Figure 10 The shape shown.

[0082] After being fixed in this manner, the end of the cable core 82 is pressed into a "U" shape, i.e., a hook shape, thereby hooking the movable plate 73. Both sides of the "U" shape are clamped, thus fixing the shape of the cable core 82. Therefore, when the cable core 82 is subjected to tension, it can effectively hook the movable plate 73, making the cable core 82 and the fixing component 7 connected as a whole, thereby improving the stability of the cable core 82 connection. Secondly, through the structure of this application, it is possible to fix quickly and stably, and the installation is simple, without the need for specific tools, thus improving the convenience of using the device.

[0083] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
