Description

Technical Field

[0001] This invention relates to the field of electrical engineering and automation technology, and in particular to an electrical engineering cable protection device. Background Technology

[0002] During the wiring process of electrical engineering cables, the conductors at both ends of two cables are fixedly connected. After the two cables are connected, the conductors at the port are exposed to the outside and need to be covered by a protective device to provide a certain degree of protection.

[0003] However, the connection ends are usually protected by an insulated box. The cable joints are supported by their own strength or by being wrapped with electrical tape for insulation. However, after a long period of use, the electrical tape will age and lose its support and insulation capabilities. At this time, the cable joints are supported by their own strength.

[0006] Preferably, the connecting unit includes a conductive sheet disposed between the two guide plates, two pressure rods disposed on the guide plates and capable of abutting against the conductive sheet, and a rotating shaft disposed on the pressure rods and rotatably connected to the guide plates.

[0007] Preferably, the lifting unit includes two gears respectively mounted on the rotating shaft, a rack mounted slidably on the guide frame and meshing with the gears, and an elastic element mounted on the guide frame and connected at both ends to the base and the rack respectively.

[0008] Preferably, the pressing unit includes two pressure rollers that are slidably disposed in the guide groove and slidably connected to the pressure rod, a limiting ring disposed on the pressure rollers, and a push rod that is slidably disposed on the guide frame and slidably connected to the limiting ring.

[0009] Preferably, the guide groove includes a short side groove and a long side groove that are connected and have an obtuse angle between them. The short side groove is arranged horizontally, and the long side groove is arranged obliquely. The push rod includes a horizontal bar portion that can be slidably connected to the limiting ring, two inclined bar portions that are provided at both ends of the horizontal bar portion, and a sliding plate that is provided on the horizontal bar portion and slidably connected to the guide frame. The angle between the horizontal bar portion and the inclined bar portion is an obtuse angle.

[0010] Preferably, the guide plate is provided with two wire clamping rollers; the wire clamping rollers are located at the short side groove of the guide groove.

[0011] Preferably, the pushing mechanism includes a moving unit slidably disposed on the guide plate and slidably connected to and abutting against the pushing rod, a sliding unit disposed on the guide plate and slidably connected to and engaged with the moving unit, and a pushing unit disposed on the pushing rod and whose output end is connected to the moving unit.

[0012] Preferably, the guide plate is provided with a mounting groove; the moving unit includes a pressure plate slidably disposed on the guide plate and located at the mounting groove and slidably connected to the push rod, an elastic element two disposed on the guide frame and connected at both ends to the push rod and the rack frame respectively, and a threaded rod disposed on the sliding unit and threadedly connected to the elastic element two.

[0013] Preferably, the sliding unit includes a mounting plate disposed on the guide plate, a support frame disposed on the mounting plate, a snap-fit ​​bracket rotatably disposed on the support frame, a torsion spring disposed on the support frame and whose output end is connected to the snap-fit ​​bracket, a guide platform disposed on the mounting plate, and a snap-fit ​​seat disposed at the lower end of the threaded rod and snap-fitted to the snap-fit ​​bracket and slidably connected to the guide platform.

[0014] Preferably, the pushing unit includes a support platform disposed on the pushing rod, a slide rod disposed on the support platform, a pushing frame slidably disposed on the slide rod and connected to the pressure plate, an elastic element disposed on the slide rod and connected at both ends to the support platform and the pushing frame respectively, and a support plate having a sliding groove disposed on the guide plate and slidably connected to the pressure plate.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: In this invention, the base and the housing are magnetically connected, and a magnet is provided at the lower end of the housing, which allows the base to be attracted to the housing. In use, the housing is opened, and two inlet holes are provided on the housing. The two cable connectors to be connected are passed through the inlet holes, with the cable connectors positioned above the clamping roller. The threaded rod is loosened, allowing the threaded rod to move downward. Pushing the threaded rod downward causes the sliding unit to guide the threaded rod, causing the threaded rod to separate from the sliding unit. This causes the lower end of the threaded rod to lose its limit, allowing the threaded rod to move upward. This quickly drives the pressure plate to move upward, causing the push rod to move upward. This causes the pressure roller to lose its squeezing force and move obliquely upward, allowing the pressure rod to flip under the push of the lifting unit. This creates a clamp between the pressure rod and the conductive sheet, allowing the cable connector to be inserted between the pressure rod and the conductive sheet.

[0016] After both cable connectors are inserted, press the threaded rod downwards to engage its lower end with the sliding unit. This fixes the lower end of the threaded rod in a relatively fixed position without affecting its rotation. Rotating the threaded rod drives the pressure plate, which in turn presses the push rod downwards. The push rod then pushes the pressure roller downwards, causing the pressure roller to flip the pressure rod downwards, thus pressing the cable connectors onto the conductive plate. The conductive plate then conducts electricity to the two cables, ensuring a reliable connection. As the pressure roller continues to move, it presses down on the outer sheath of the cables. The clamping rollers, in conjunction with the pressure rollers, clamp the cable sheath, supporting the cable and preventing stress on the cable joint. This ensures the stability of the cable joint and prevents it from breaking, thus protecting the cable. The housing is then placed back on the base and secured magnetically. The cable itself provides some tension, and the housing creates a relatively sealed space for the cable joint. The inlet hole is blocked by the cable sheath, and a sealing gasket is placed at the inlet hole, pressing against the cable sheath to prevent dust from entering the cable joint.

[0017] During disassembly, simply open the housing, loosen the threaded rod, and then detach the threaded rod from the sliding unit. This allows the pressure rod to spring up quickly, making it easy to remove the cable and achieve rapid disassembly. When multiple cables need to be connected, multiple units can be prepared, connected sequentially, and then placed on a storage rack for convenient storage. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0024] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0025] Example 1 like Figure 1-11 As shown, the present invention proposes an electrical engineering cable protection device, which includes a frame 1, a connecting unit 2, a guide frame 3, a lifting unit 4, a pressing unit 5, and a pushing mechanism; Frame 1 includes a base 101, a housing 102 detachably connected to the base 101, and two guide plates 104 mounted on the base 101. Two guide grooves 105 are symmetrically arranged on the guide plates 104. A connecting unit 2 is mounted on the base 101 and rotatably mounted on the guide plates 104. The connecting unit 2 includes a conductive sheet 201 positioned between the two guide plates 104, two pressure rods 202 rotatably mounted on the guide plates 104 and capable of abutting against the conductive sheet 201, and a rotating shaft 203 mounted on the pressure rods 202 and rotatably connected to the guide plates 104. A guide frame 3 is mounted on the base 101. A lifting unit 4 is slidably mounted on the guide frame 3 and drivenly connected to the connecting unit 2. A pressing unit 5 is slidably mounted on the guide plate 104, with one end slidably mounted within the guide groove 105 and abutting against the pressure rod 202. A pushing mechanism is mounted on the guide plate 104, and its output end is connected to the pressing unit 5.

[0026] In this embodiment, the base 101 is magnetically connected to the housing 102. A magnet is provided at the lower end of the housing 102, which allows the base 101 to be attracted to the housing 102. In use, the housing 102 is opened, and two wire inlet holes 103 are provided on the housing 102. The two cable connectors to be connected are passed through the wire inlet holes 103, so that the cable connectors are above the clamping roller 204. The threaded rod 603 is loosened, so that the threaded rod 603 has room to move downward. The threaded rod 603 is pushed downward, so that the sliding unit 7 engages with the threaded rod 603. 3. The guide causes the threaded rod 603 to separate from the sliding unit 7, thereby removing the limit at the lower end of the threaded rod 603 and allowing it to move upward. This causes the pressure plate 601 to move upward quickly, which in turn causes the push rod 503 to move upward. Consequently, the pressure roller 501 loses its squeezing force and moves obliquely upward, allowing the pressure rod 202 to flip under the push of the lifting unit 4. This creates a clamp between the pressure rod 202 and the conductive sheet 201, enabling the cable connector to be inserted between the pressure rod 202 and the conductive sheet 201.

[0027] After both cable connectors are inserted, press the threaded rod 603 downwards to engage its lower end with the sliding unit 7. This fixes the lower end of the threaded rod 603 in a relatively fixed position without affecting its rotation. Rotating the threaded rod 603 drives the pressure plate 601 to move, causing it to press the push rod 503 downwards. The push rod 503 then pushes the pressure roller 501 downwards, which in turn pushes the pressure rod 202 downwards, pressing the cable connectors onto the conductive sheet 201. The conductive sheet 201 then conducts electricity to the two cables, ensuring a reliable connection. As the pressure roller 501 continues to move... The outer sheath of the cable is pressed onto the clamping roller 204. The pressure roller 501, in conjunction with the clamping roller 204, clamps the cable sheath, supporting the cable and preventing stress on the cable joint. This ensures the stability of the cable joint and prevents it from breaking under stress, thus protecting the cable. The housing 102 is then placed back onto the base 101 and secured magnetically. The cable itself is also pulled in a relatively tight manner. The housing 102 creates a relatively sealed space for the cable joint, while the inlet hole 103 is blocked by the cable sheath. A sealing gasket is placed at the inlet hole 103, pressing against the cable sheath to prevent dust from entering the cable joint.

[0028] During disassembly, simply open the housing 102, loosen the threaded rod 603, and then detach the threaded rod 603 from the sliding unit 7. This allows the pressure rod 202 to spring up quickly, making it easy to remove the cable and achieve quick disassembly. When multiple cables need to be connected, multiple units of this device can be prepared, connected sequentially, and then placed on a storage rack for convenient use.

[0029] Example 2 like Figure 1-11 As shown, the present invention proposes an electrical engineering cable protection device. Compared with Embodiment 1, the lifting unit 4 in this embodiment includes two gears 401 respectively mounted on the rotating shaft 203, a rack frame 402 slidably mounted on the guide frame 3 and meshing with the gears 401, and an elastic element 403 mounted on the guide frame 3 and connected at both ends to the base 101 and the rack frame 402 respectively. The pressing unit 5 includes two pressure rollers 501 slidably mounted in the guide groove 105 and slidably connected to the pressure rod 202, a limiting ring 502 mounted on the pressure rollers 501, and a push rod 503 slidably mounted on the guide frame 3 and slidably connected to the limiting ring 502.

[0030] In this embodiment, when the pressure rod 202 is not under the pressure of the pressure roller 501, the elastic element 403 pushes the rack frame 402 to move upward. The rack frame 402 simultaneously drives the two gears 401 to rotate. The gears 401 drive the rotating shaft 203 to rotate. The rotating shaft 203 drives the pressure rod 202 to rotate, so that the pressure rod 202 can flip upward, thereby creating an angle between the pressure rod 202 and the conductive sheet 201, which facilitates the placement of the cable connector between the conductive sheet 201 and the pressure rod 202.

[0031] By flipping the pressure rod 202, the pressure roller 501 can be pushed to move obliquely upward, and the push rod 503 can be pushed upward by the elastic element 602 set on the rack frame 402, thereby quickly releasing the limit and allowing the pressure rod 202 to open quickly, which is convenient for clamping and fixing the cable connector.

[0032] Example 3 like Figure 1-11 As shown, the present invention proposes an electrical engineering cable protection device. Compared with Embodiment 1 or Embodiment 2, the guide groove 105 in this embodiment includes a short side groove and a long side groove that are connected and have an obtuse angle. The short side groove is arranged horizontally, and the long side groove is arranged obliquely. The push rod 503 includes a horizontal rod portion 5031 that can be slidably connected to the limiting ring 502, two inclined rod portions 5032 that are provided at both ends of the horizontal rod portion 5031, and a sliding plate 5033 that is provided on the horizontal rod portion 5031 and slidably connected to the guide frame 3. The angle between the horizontal rod portion 5031 and the inclined rod portion 5032 is an obtuse angle. Two wire clamping rollers 204 are provided on the guide plate 104. The wire clamping rollers 204 are located at the short side groove of the guide groove 105.

[0033] In this embodiment, the cable connector is placed between the conductive sheet 201 and the pressure rod 202 from above the clamping roller 204. When the push rod 503 moves downward, the crossbar 5031 pushes the limiting ring 502 downward. The limiting ring 502 drives the pressure roller 501 downward, and the limiting ring 502 is used to prevent the pressure roller 501 from falling out of the guide groove 105. At this time, the pressure roller 501 first slides diagonally downward in the long side groove, pushing the pressure rod 202 to flip downward, so that the pressure rod 202 presses on the cable connector. When the pressure roller 501 moves to the short side groove, the pressure rod 202 is pressed down to the maximum position, which can firmly clamp the cable connector and prevent the cable connector from coming off. The push rod 503 continues to move downward. At this time, the diagonal bar 5032 contacts the limiting ring 502, so that the pressure roller 501 faces the short side groove. As the cable moves downward, the short side groove blocks the push of the pressure rod 202, reducing the force on the push rod 503 and preventing loosening. Simultaneously, the inclined rod 5032 pushes the pressure roller 501 towards the clamping roller 204. With part of the cable on the clamping roller 204, the pressure roller 501 presses the cable onto it, securing it. The cable sheath provides support, protecting the cable joint and preventing breakage. The sheath size can be adjusted according to its dimensions; a smaller sheath allows for greater downward movement of the push rod 503, further protecting the cable and ensuring a reliable connection without circuit breakage, thus guaranteeing the normal operation of the electrical equipment.

[0034] Since the position of the rotating shaft 203 is lower than the position of the guide groove 105, even after the pressure roller 501 slides into the short side groove, the pressure rod 202 still has a certain tilt angle. Therefore, when the push rod 503 is moved upward, the lifting unit 4 pushes the rotating shaft 203 to rotate, and the rotating shaft 203 drives the pressure rod 202 to rotate, so that the pressure rod 202 squeezes the pressure roller 501, causing the pressure roller 501 to move towards the long side groove, thereby enabling the pressure roller 501 to move into the long side groove and preventing the pressure roller 501 from getting stuck in the short side groove.

[0035] Example 4 like Figure 1-11 As shown, the electrical engineering cable protection device proposed in this invention, compared with Embodiment 1, Embodiment 2 or Embodiment 3, has a pushing mechanism in this embodiment, including a moving unit 6 that is slidably disposed on the guide plate 104 and slidably connected to and abutting against the pushing rod 503, a sliding unit 7 that is disposed on the guide plate 104 and slidably connected to and locked with the moving unit 6, and a pushing unit 8 that is disposed on the pushing rod 503 and whose output end is connected to the moving unit 6.

[0036] Furthermore, the guide plate 104 is provided with an installation groove; the moving unit 6 includes a pressure plate 601 slidably disposed on the guide plate 104 and located at the installation groove and slidably connected to the push rod 503, an elastic element 602 disposed on the guide frame 3 and connected at both ends to the push rod 503 and the rack frame 402 respectively, and a threaded rod 603 disposed on the sliding unit 7 and threadedly connected to the elastic element 602; the moving unit 6 can drive the push rod 503 to move downward, so that the push rod 503 presses the pressure roller 501 downward, thereby causing the pressure rod 202 to flip and press on the cable.

[0037] Furthermore, the sliding unit 7 includes a mounting plate 701 disposed on the guide plate 104, a support frame 702 disposed on the mounting plate 701, a snap-fit ​​frame 703 rotatably disposed on the support frame 702, a torsion spring 7031 disposed on the support frame 702 and whose output end is connected to the snap-fit ​​frame 703, a guide platform 704 disposed on the mounting plate 701, and a snap-fit ​​seat 705 disposed at the lower end of the threaded rod 603 and snap-fitted to the snap-fit ​​frame 703 and slidably connected to the guide platform 704; the sliding unit 7 can guide the pressure plate 601 when the pressure plate 601 is pressed down, so that the pressure plate 601 moves downward at an angle, thereby separating the pressure plate 601 from the sliding unit 7, and can spring up the pressure plate 601 to quickly drive the push rod 503 to lift upward, so that the pressure rod 202 opens, making it convenient to place or pull out the cable.

[0038] Furthermore, the pushing unit 8 includes a support platform 801 mounted on the pushing rod 503, a slide rod 802 mounted on the support platform 801, a pushing frame 804 slidably mounted on the slide rod 802 and connected to the pressure plate 601, an elastic element 803 mounted on the slide rod 802 and connected at both ends to the support platform 801 and the pushing frame 804 respectively, and a support plate 805 having a sliding groove 8051 mounted on the guide plate 104 and slidably connected to the pressure plate 601; the pushing unit 8 can push the pressure plate 601 to reset, so that the pressure plate 601 can automatically move above the snap-fit ​​bracket 703 after being pressed down and popped up, and can automatically snap into the snap-fit ​​bracket 703 when pressed down, so as to facilitate the snap-fit ​​of the moving unit 6 into the sliding unit 7.

[0039] In this embodiment, the snap-fit ​​bracket 703 is provided with a U-shaped groove 7032 and a snap-fit ​​groove 7033. In the initial state, the snap-fit ​​seat 705 is snapped in the snap-fit ​​groove 7033, and the elastic element 2 602 is located in the U-shaped groove 7032. At this time, due to the force of the elastic element 1 403, the push rod 503 has an upward force, thereby pushing the moving unit 6 upward, thereby causing the threaded rod 603 to move upward. The threaded rod 603 drives the snap-fit ​​seat 705 to snap onto the snap-fit ​​bracket 703 and embed it in the snap-fit ​​groove 7033, making it impossible to slide out. Therefore, the lower end of the threaded rod 603 is in a relatively fixed state. When the threaded rod 603 is rotated at this time, it can drive the pressure plate 601 to move, thereby pressing the push rod 503 downward, so that the pressure rod 202 presses on the cable connector, so that the cable connector can conduct electricity through the conductive sheet 201.

[0040] Before inserting the cable connector, to facilitate its insertion, the threaded rod 603 drives the pressure plate 601 to move upward slightly, allowing the pressure plate 601 to slide downward. This provides the threaded rod 603 with some sliding space. Then, pushing the threaded rod 603 downward causes the snap-fit ​​seat 705 to move out of the snap-fit ​​groove 7033, bringing it into contact with the guide table 704. The guide table 704, being an inclined structure, guides the snap-fit ​​seat 705, causing it to move downward at an angle. This moves the threaded rod 603, causing it to move out of the U-shaped groove 7032. This shifts the position of the threaded rod 603 relative to the snap-fit ​​bracket 703. Maintaining this offset, the threaded rod 603 is moved upward, ensuring that the snap-fit ​​seat 705 is fully engaged with the snap-fit ​​bracket 703. Separate and move above the clip holder 703. At this time, since the lower end of the threaded rod 603 is no longer restrained, the threaded rod 603 can move directly upward. Through the elastic element 602, the push rod 503 is pushed upward, and the push rod 503 drives the pressure plate 601 to move upward, thereby quickly releasing the limit and allowing the push rod 503 to move completely upward. This causes the pressure roller 501 to move upward, opening the pressure rod 202 and exposing the position between the conductive sheet 201 and the pressure rod 202. This allows the cable connector to be easily inserted between the conductive sheet 201 and the pressure rod 202, and has a large opening, making it easy to insert the cable connector. This allows for quick release of the limit by pressing down, making it easy to open the pressure rod 202. After the cable connector is placed, the cable can be easily removed after the pressure rod 202 is opened, achieving quick disassembly.

[0041] When the cable connector is placed between the pressure bar 202 and the conductive plate 201, the moving unit 6 is in a relaxed state. Therefore, the slide bar 802 guides the push frame 804, and the elastic element 803 pushes the push frame 804 to move. The push frame 804 moves the pressure plate 601, which in turn moves the threaded rod 603. This causes the threaded rod 603 to move the snap-fit ​​seat 705 above the snap-fit ​​frame 703, aligning the snap-fit ​​seat 705 with the snap-fit ​​frame 703 and returning it to its original position. Pressing down on the threaded rod 603 causes it to drive the snap-fit ​​seat 705 into contact with the snap-fit ​​bracket 703. The snap-fit ​​bracket 703 is rotatably mounted on the support frame 702. Therefore, the snap-fit ​​bracket 703 rotates, allowing the snap-fit ​​seat 705 to move downwards. Once the snap-fit ​​seat 705 has completely passed the snap-fit ​​bracket 703, the torsion spring 7031 drives the snap-fit ​​bracket 703 to flip, and the upper snap-fit ​​bracket 703 returns to its original position. At this point, the threaded rod 603 is embedded in the U-shaped groove 7032, and the snap-fit ​​seat 705 is positioned in the snap-fit ​​position. Below the groove 7033, the threaded rod 603 is moved directly upwards. That is, before the threaded rod 603 tilts downwards, it is lifted upwards, causing the threaded rod 603 to drive the locking seat 705 into the locking bracket 703. This allows the locking bracket 703 to limit the locking seat 705, and the locking seat 705 to limit the threaded rod 603, ensuring that the lower end of the threaded rod 603 is in a relatively fixed position and can be supported by force. This allows the pressure plate 6 to be driven when the threaded rod 603 rotates. 01. When the driving pressure plate 601 moves downward, it will push the push rod 503 downward. The push rod 503 will push the pressure roller 501 downward, causing the pressure roller 501 to push the pressure rod 202 downward to flip, thereby clamping it on the cable connector. This will press the cable connector onto the conductive sheet 201 to fix the cable connector, allowing the two cables to conduct electricity through the conductive sheet 201, completing the connection between the two cables. The connection is highly reliable and will not fall off.

[0042] This structure allows for the rapid lifting of the pressure rod 202, facilitating the insertion of the cable connector between the conductive plate 201 and the pressure rod 202 for electrical connection. It also allows for quick removal of the cable connector after the pressure rod 202 is lifted, enabling rapid disassembly. Furthermore, the structure of the cable connector is not critical; simply peel off the outer sheath of the connector and insert it directly. The pressure rod 202 then presses against the conductive plate 201 to secure the wire core, thus completing the rapid connection.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
