Description

Technical Field

[0001] This invention relates to the field of cable connection technology, and in particular to a bypass quick-plug cable connector. Background Technology

[0002] In uninterrupted power supply maintenance, line modification, and load transfer operations in medium-voltage distribution networks, bypass operations are often used to connect or transfer operating cables with temporary bypass cables in parallel to ensure uninterrupted power supply to users. In bypass operation systems, operators typically need to reliably insert the bypass cable terminal into the corresponding connection cavity or cable insertion hole. However, in actual operating environments, existing quick-plug cable terminals generally have the following problems: Bypass cable connectors generally require a large insertion force, especially medium-voltage cable terminals. Their connection points are typically designed to be quite tight to ensure reliable electrical contact and sealing performance, requiring operators to apply significant axial force to complete insertion. Manual insertion and removal can easily lead to difficulties in insertion, incomplete insertion, misaligned insertion, or even damage to the connector components, thus affecting the quality of electrical contact and creating potential safety hazards.

[0003] Bypass operations typically occur in confined spaces such as cable wells and around transformer substations. Due to limitations in installation posture, operating space, and cable routing, it is difficult to maintain the axial consistency of the plug during manual operation. The lack of an effective guiding structure makes precise alignment between the plug and the insertion hole difficult, often leading to increased insertion force and repeated alignment attempts, resulting in wasted time and decreased work efficiency.

[0004] Existing quick-connect terminals generally rely on manual experience to complete the entire process of alignment, positioning, and application of insertion force, lacking precise and reliable positioning mechanisms and mechanical assistance structures that can significantly reduce operating force. Operators need to maintain a stable posture and apply significant pushing force, resulting in high labor intensity. The stability and success rate of the connection are significantly affected by human factors, easily leading to problems such as repeated insertion and removal, poor contact, or connection failure, increasing the risks of on-site operations. Summary of the Invention

[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0020] Reference Figure 1-6 This embodiment provides a bypass quick-plug cable connector, including a quick-plug cable plug 1, a cable insertion hole 2 for inserting the quick-plug cable plug 1, and an auxiliary insert 3 disposed outside the cable insertion hole 2; the cable insertion hole 2 is fixedly disposed in the housing 4; the auxiliary insert 3 is used to push the quick-plug cable 1 so that the quick-plug cable 1 is inserted into the cable insertion hole 2.

[0021] The auxiliary insert 3 includes a mounting body 31, a mounting cylinder 32 slidably disposed on the mounting body 31, a pressure rod 33 rotatably disposed on the mounting body 31 for pressing the bottom of the mounting cylinder 32, and a positioning member 34 disposed on the mounting body 31 for ensuring the insertion direction position. The pressure rod 33 has a pressing arm and a working arm, the length of which is greater than the length of the working arm to amplify the insertion force through a lever structure. In this embodiment, the pressure rod 33 is made of steel, with a rubber coating at the end to improve hand grip. The pressure rod 33 is connected to the mounting body 31 via a pivot and can swing within a range of 0° to 90° to provide a stable pressing force output.

[0022] The positioning component 34 includes a magnet 341 disposed on one side of the mounting body 31 for adsorbing onto the housing 4; a magnet switch 342 disposed on the mounting body 31 for controlling the adsorption and release of the magnet 341; and a positioning hole 343 disposed on the housing 4 for accommodating the magnet 341 for positioning. In this embodiment, the magnet 341 is a high-temperature resistant rare-earth permanent magnet with a magnetic force range of 10–30 N, ensuring stable adsorption even in outdoor windy conditions. The magnet switch 342 can be a toggle-type mechanical structure, switching the magnetic force through the extension and retraction of a magnetic shield.

[0023] The mounting cylinder 32 has a mounting groove 321 for accommodating the wire of the quick-connect cable plug 1, and an opening 322 at the bottom of the mounting cylinder 32. The mounting groove 321 and the opening 322 are connected through each other to accommodate the tail wire of the quick-connect cable plug 1 inside the mounting cylinder 32. In this embodiment, the width of the mounting groove 321 is slightly larger than the outer diameter of the cable by 2-5 mm, so that the wire can be smoothly accommodated and avoids lateral swinging during insertion. The mounting cylinder 32 is made of reinforced nylon or aluminum alloy, which can ensure lightweight design and withstand the axial impact of the insertion force.

[0024] The mounting cylinder 32 is provided with a return element 5 for returning the mounting cylinder 32 to its initial position; the return element 5 includes a compression spring 51, one end of which is connected to the mounting body 31 and the other end is connected to the mounting cylinder 32.

[0025] The mounting body 31 is equipped with a handle 6, which allows the operator to align the magnet 341 with the positioning hole 343. In this embodiment, the handle 6 adopts an ergonomic curved structure with anti-slip texture on the surface, allowing for one-handed gripping and moving the auxiliary insert 3 to the corresponding position on the outside of the housing 4, thereby improving positioning accuracy.

[0026] The mounting body 31 is provided with a lifting screw 7, which is used to adjust the stroke distance of the pressure rod 33 pressing the mounting cylinder 32. In this embodiment, the lifting screw 7 is screwed into the threaded hole of the mounting body 31, and the length can be adjusted by rotation, thereby accurately setting the downward limit position of the pressure rod 33, ensuring that the quick plug insertion depth is consistent, and avoiding excessive compression that could cause end damage.

[0027] A clamping member 8 is rotatably mounted on the lifting screw 7. The clamping member 8 is used to clamp the wires of the cable plug during insertion.

[0028] The clamping component 8 includes a rotating block 81 rotatably mounted on the lifting screw 7, a first chuck 82 and a second chuck 83 slidably mounted on the rotating block 81, and a rotating screw 84 passing through the first chuck 82 and the second chuck 83. The rotating screw 84 is connected to the first chuck 82 and the second chuck 83 by threads in opposite directions, and is used to simultaneously tighten or loosen the first chuck 82 and the second chuck 83 when the screw 84 rotates. In this embodiment, a rubber gasket is provided on the inner side of the chuck to protect the cable sheath from damage during clamping. The rotation of the screw is accomplished by a handle 6, which allows the operator to easily adjust the screw while wearing insulated gloves.

[0029] A counterweight 9 is provided at the bottom of the rotating block 81 to keep the clamping jaws between the first clamp 82 and the second clamp 83 vertical. In this embodiment, the counterweight 9 is made of stainless steel, which allows the clamps to automatically swing downwards in a vertical direction when the wire is not clamped, which facilitates the quick placement of the wire into the clamping jaws and improves work efficiency and stability.

[0030] Working Principle: In the use of this invention, the operator first inserts the wire of the quick cable plug 1 into the mounting groove 321 and bottom opening 322 of the mounting cylinder 32, and clamps the wire using the clamping member 8. The first clamp 82 and the second clamp 83 in the clamping member 8 synchronously retract under the reverse thread drive of the rotating screw 84, firmly clamping the wire in the clamping position. Through the traction force generated by the clamped wire, the quick cable plug 1 is reliably limited in the insertion port of the mounting cylinder 32, thereby preventing shaking, swaying, or displacement during subsequent insertion, ensuring a stable and consistent insertion posture.

[0031] Subsequently, the operator holds the handle 6 on the mounting body 31 and pushes the auxiliary insert 3 into the inner side of the housing 4, aligning the magnet 341 on the mounting body 31 with the positioning hole 343 of the housing 4. The magnet 341 is attracted into the positioning hole 343 in the open state. This magnetic positioning structure enables the auxiliary insert 3 to be automatically oriented relative to the cable insertion hole 2, ensuring that the central axis of the quick cable plug 1 precisely coincides with the central axis of the cable insertion hole 2, effectively avoiding misalignment, off-center insertion, or connection difficulties caused by manual visual alignment errors.

[0032] After axial alignment is achieved, the operator grasps the pressing arm of the pressure lever 33 and applies downward force. Because the pressing arm of the pressure lever 33 is longer than the working arm, the lever amplification principle significantly increases the pushing force applied to the mounting cylinder 32, causing the mounting cylinder 32 to move forward along the sliding direction, thereby stably pushing the quick-connect cable plug 1 into the cable insertion hole 2. The guiding structure of the mounting cylinder 32 further restricts the insertion direction, preventing lateral swaying during insertion, ensuring the plug can be inserted smoothly and axially.

[0033] As the pressure rod 33 continues to press down, the quick cable plug 1 gradually and completely enters the cable insertion hole 2 and achieves a reliable electrical connection. When the pressure rod 33 reaches the limit stroke set by the lifting screw 7, the lifting screw 7 limits the downward stroke of the pressure rod 33 to ensure that the quick cable plug 1 reaches the standard insertion depth and avoids damage to the connector structure or deformation of the sealing component due to over-insertion.

[0034] After the insertion is completed, the operator releases the pressure rod 33. The mounting cylinder 32 automatically rises and resets under the action of the compression spring 51 in the return piece 5, restoring the auxiliary insert 3 to its initial state for the next insertion operation. Subsequently, the operator closes the magnet switch 342, disengaging the magnet 341 from the positioning hole 343 in the housing 4, allowing for easy removal of the auxiliary insert 3 or switching to the next phase to continue operation.

[0035] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
