Description

Technical Field

[0001] This invention relates to the field of communication cable connection, specifically to a branch drainage connection device based on T-shaped groove guidance. Background Technology

[0002] In power transmission, communication networks, and various industrial cabling systems, it is often necessary to branch the backbone cable to distribute electrical signals or power. Such connections not only require reliable electrical contact and a stable mechanical connection, but also often need to be installed and adjusted quickly without disconnecting the backbone line to adapt to complex field cabling environments and diverse wire gauges.

[0003] Currently, common branch connection devices mostly employ methods such as bolt crimping, piercing clamps, or insulation piercing. Bolt crimping devices are cumbersome to install, require specialized tools, and may damage the cable surface. While piercing clamps can be installed under energized conditions, the depth and pressure control rely heavily on operator experience, easily leading to poor contact or over-piercing that damages the cable insulation. Furthermore, existing branch connection devices are mostly fixed designs, with limited adjustment ranges for installation position, clamping force, and angle, making them difficult to adapt to different wire diameters, spatial layouts, and subsequent line adjustments. Especially in densely packed distribution boxes, cable trays, or towers with limited space, existing devices often suffer from inconvenient installation, difficult adjustment, and poor versatility.

[0004] The existing branch connection devices have the following main shortcomings: First, the installation and adjustment process is complex, making it difficult to achieve fast and accurate positioning and fixing; second, the clamping mechanism is simple, with insufficient adaptability and protection for cables, which can easily cause cable damage or unstable contact resistance; third, the overall structure lacks flexible guidance and modular design, making it difficult to freely combine and expand according to the site space and wiring requirements, resulting in limited applicability and low construction efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a branch drainage connection device based on T-shaped chute guidance, so as to solve the technical problems of existing branch connection devices having fixed installation positions, inconvenient adjustment, easy damage to cables when clamped, and unreliable electrical contact.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a branch drainage connection device based on a T-shaped chute guide, comprising: a frame unit including a top component and a bottom component, the top component and the bottom component being detachably connected by a connecting rod to form a three-dimensional frame with a T-shaped guide channel; multiple connecting components, slidably and lockably disposed within the T-shaped guide channel of the frame unit, for clamping cables at predetermined positions; and an integrated clamping and conducting mechanism disposed within the connecting components, including: a drive input end disposed at the bottom. The system includes: a component for receiving external driving force; a transmission conversion module connected to the drive input end for converting the received single-point driving force into a bidirectional centering clamping force; clamping elements consisting of a pair of symmetrically arranged conductive pressure plates, movably mounted on the transmission conversion module, for simultaneously clamping the cable from both vertical and horizontal directions under the bidirectional centering clamping force; and an electrical conduction element connected to the clamping elements, which establishes and maintains a low-resistance electrical path from the cable to the connecting assembly when the clamping elements clamp the cable. The drive input end is a slidable extrusion plate with a drive section at its front end, which pushes the first transmission component of the integrated clamping and conduction mechanism during sliding.

[0007] The present invention is further configured such that the transmission conversion module further includes: a first transmission member connected to the drive input end and movable in a first direction; a second transmission member slidably engaged with the first transmission member through a guide structure to convert the movement in the first direction into its own unidirectional movement; and a reversing mechanism including at least a pair of opposing slidable pressing blocks and a lower push rod engaged with the pressing blocks, for converting the movement direction of the second transmission member into a second direction opposite to the first direction, thereby driving the pair of conductive pressure plates to move synchronously in a centered manner.

[0008] The invention is further configured such that the first transmission component is an upper push rod with an upper push block at its top; the second transmission component is a push rod with a pair of symmetrical extrusion blocks inside; the lower push rod is located between the pair of extrusion blocks and cooperates with the inclined surface of the lower push rod through a push pin. When the upper push rod pushes upward, it drives the push rod to move upward, thereby causing the extrusion blocks to slide inward and driving the lower push rod to press downward.

[0009] The present invention is further configured such that the electrical conducting element is a pressure member, which is respectively disposed at the ends of the upper top block and the lower top rod, and is electrically connected to the pair of conductive pressure plates respectively; when the upper top block and the lower top rod move in opposite directions, the pressure member will uniformly transmit the clamping force to the clamping element and ensure the electrical contact stability between the clamping element and the cable.

[0010] The present invention is further configured such that the connecting component includes: an upper connector, slidably disposed in a groove of the top component, with the top clamping element disposed on its inner side; and a lower connector, slidably disposed in a groove of the bottom component, with the bottom clamping element disposed on its inner side; wherein the integrated clamping and guiding mechanism is integrated between the upper connector and the lower connector.

[0011] The present invention is further configured such that connecting blocks are provided on both sides of the upper connecting member and the lower connecting member, and the connecting blocks are detachably connected by a fixing rod, which is used to enhance the structural integrity of the upper connecting member and the lower connecting member in the clamping state.

[0012] The invention is further configured to include a mounting base, which is detachably mounted on the bottom surface of the bottom component, and the extrusion plate is slidably disposed on the mounting base.

[0013] The present invention is further configured such that the end of the mounting base away from the top pressure plate is provided with a wire mounting port for connecting external lines; The present invention is further configured such that one end of the mounting base is provided with a top pressure plate and the other end is provided with a wire mounting port; the top pressure plate is used to drive the extrusion plate to slide; the wire mounting port is used to connect branch lines.

[0014] The invention is further configured to include a manual operating mechanism, comprising a mounting rod, a transmission wheel mounted on the mounting rod, and a mounting trigger; a cable is wound around the transmission wheel, one end of the cable is connected to the mounting trigger, and the other end is connected to the top pressure plate, so that the top pressure plate can be remotely driven to move by operating the mounting trigger.

[0015] The invention is further configured such that a drive shaft and a knob are provided in the T-shaped guide channel of the frame unit for driving the connecting assembly to move along the slide and be precisely positioned; a fixing groove and a limiting rod cooperating therewith are provided on the side wall of the slide for locking the connected assembly after it has moved.

[0016] In summary, the present invention has the following main beneficial effects: This invention employs a symmetrical and modular T-shaped chute frame structure, coupled with connectors that can be precisely adjusted and locked along the chute, achieving high flexibility and adaptability in installation position. This effectively solves the problems of inconvenient installation and limited adjustment range in existing devices. It innovatively designs a linkage clamping mechanism consisting of a push rod, guide groove, extrusion block, and push pin. Under single-point drive, it can achieve synchronous centering and clamping of the upper and lower transmission pressure plates. The clamping process is stable and reliable and can adapt to different wire diameters, overcoming the shortcomings of traditional piercing or crimping methods that easily damage cables and cause uneven contact. Furthermore, it integrates modular drive and branch interfaces. Through the flexible configuration of the mounting base at the bottom of the chute and the trigger transmission mechanism, it achieves remote operation and labor-saving control, enhancing the convenience and safety of construction in confined spaces. The overall device structure has a high degree of modularity and strong expandability, combining stable mechanical clamping with reliable electrical connections, significantly improving the efficiency and reliability of branch connection operations.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] A branch drainage connection device based on T-shaped groove guidance, such as Figure 1-7 As shown, the core structure of the device consists of three main parts: a frame unit for providing the installation foundation and guide path, multiple adjustable connection components for clamping and connecting the main line cable, and an integrated clamping and conduction mechanism integrated inside each connection component for achieving clamping and electrical conduction.

[0022] Specifically, the frame unit is the supporting skeleton of the entire device, comprising a top component and a bottom component. The top and bottom components are detachably connected by multiple connecting rods 29. When the connecting rods 29 assemble the top and bottom components, they together form a three-dimensional frame with an internal T-shaped guide channel. This T-shaped guide channel design provides a basis for the precise installation and positioning adjustment of subsequent connecting components.

[0023] Multiple connecting components are slidably mounted within this T-shaped guide channel. Each connecting component can not only move within the channel in a predetermined direction (along the main cable route) to accommodate connection needs at different locations, but can also be secured in a predetermined position within the channel via a specific locking mechanism. Its primary function is to securely clamp the cable (i.e., the main line cable) passing through the frame unit at the predetermined position.

[0024] The core improvement of this invention lies in an integrated clamping and conducting mechanism, which is ingeniously integrated inside each connecting component. This mechanism, through a series of transmission conversions, transforms the externally applied single-point driving force into a bidirectional centering clamping force, and establishes a reliable electrical path while clamping.

[0025] In detail, the integrated clamping and conducting mechanism includes: A drive input end: This input end is located on the bottom component, specifically a sliding extrusion plate 13. The operator can push the extrusion plate 13 to slide on the bottom component in various ways (such as manually, by tool, or remotely). The front end of the extrusion plate 13 is provided with a drive unit. When the extrusion plate 13 is pushed, its drive unit pushes forward the first transmission member 21 of the integrated clamping and guiding mechanism, thereby inputting external driving force into the mechanism.

[0026] A transmission conversion module: This module is connected to the drive input end, and its core function is to convert the single-point driving force input from the extrusion plate 13 in one direction into a bidirectional centering clamping force that drives the top and bottom clamping elements to move in opposite directions. To achieve this complex force conversion, this module typically contains multiple transmission components.

[0027] A pair of clamping elements: These are a pair of symmetrically arranged conductive pressure plates 18, which are movable relative to each other at the output end of the transmission conversion module. For example, the top conductive pressure plate 18 can be mounted on the upper connector 3, and the bottom conductive pressure plate 18 can be mounted on the lower connector 17. When the transmission conversion module generates a bidirectional centering clamping force, this force drives the pair of symmetrically arranged conductive pressure plates 18 to move closer and finally clamp the cable located between them synchronously from both directions.

[0028] An electrical conductive element: This element and the clamping element are electrically connected to a pair of symmetrically arranged conductive pressure plates 18. When the clamping element clamps the cable under bidirectional centering force, the electrical conductive element is compressed, thereby establishing a low-impedance, reliable electrical path between the clamping element and the cable. This path ensures that the current in the cable can flow smoothly to the entire connection assembly, and then be led out through branch lines to achieve the function of branch current diversion.

[0029] Next, a specific and preferred embodiment of the transmission conversion module will be described in detail, wherein the transmission conversion module further includes: The first transmission member 21 is in direct contact with or connected to the drive input end (the drive portion of the extrusion plate 13). When the extrusion plate 13 slides, its drive portion pushes the first transmission member 21 upward, causing it to move in a first direction (e.g., vertically upward). In this embodiment, the first transmission member 21 may be a vertically arranged upper push rod.

[0030] The second transmission component 22 is slidably engaged with the first transmission component 21 via a guide structure 31. For example, the second transmission component 22 (which may be called a punch rod) can be hollow and sleeved outside the first transmission component 21, or connected to the first transmission component 21 via a guide rail, groove, or other means. When the first transmission component 21 moves upward, it will drive the second transmission component 22 to move in the same direction (i.e., in the same direction) via the guide structure 31. However, the motion relationship between the two is not a simple rigid connection, but allows relative motion under certain conditions.

[0031] Reversing Mechanism: This mechanism is crucial for achieving force direction conversion. In this embodiment, the reversing mechanism includes at least a pair of opposing sliding compression blocks 25 and a lower push rod 27 that cooperates with the compression blocks 25. Specifically, a pair of compression blocks 25 are symmetrically arranged in the internal space of the second transmission member 22, and they can slide relative to each other in the horizontal direction. Each compression block 25 has an inclined surface, and the upper end of the lower push rod 27 has one or a pair of push pins 26, the ends of which contact the inclined surface of the lower push rod 27. When the second transmission member 22 is driven upward by the first transmission member 21, the lower push rod 27 is forced to slide inward along the inclined surface due to the constraint of the frame or housing. The inward sliding of the compression blocks 25, through the cooperation of the inclined surface and the push pins 26, converts its horizontal movement into a vertical force driving the lower push rod 27 downward. Thus, the upward movement of the first transmission member 21 (first direction) is ultimately converted into the downward movement of the lower push rod 27 (second direction, opposite to the first direction). The top conductive pressure plate 18 is connected to the upper connector 3 and is subjected to a downward pushing force from the first transmission component 21; the bottom conductive pressure plate 18 is connected to the lower connector 17 and is subjected to an upward pushing force from the lower push rod 27. Together, they achieve synchronous centering and clamping of the cable.

[0032] More specifically, the first transmission member 21 has an upper push block 23 at its top. The second transmission member 22 has a pair of symmetrically arranged pressing blocks 25 inside. The lower push rod 27 is located between these pressing blocks 25. The top of the lower push rod 27 engages with the inclined surface of the lower push rod 27 via a push pin 26. Its working process is as follows: when the upper push rod is pushed upward by the pressing plate 13, it first drives the upper push block 23 upward, and simultaneously drives the second transmission member 22 upward through the guide structure 31. The upward movement of the second transmission member 22 forces the pressing blocks 25 inside to slide inward along the inclined surface under the action of the surrounding shell or limiting structure. When the pressing blocks 25 slide inward, they apply pressure to the push pin 26, thereby pushing the lower push rod 27 downward relative to the second transmission member 22. Finally, the upper push block 23 and the lower push rod 27 move in opposite directions in the vertical direction, respectively applying clamping force to a pair of symmetrically arranged conductive pressure plates 18.

[0033] To achieve a stable electrical connection, the electrical conducting element is preferably a pressure member 24 with good conductivity. These pressure members 24 are respectively disposed at the ends of the upper top block 23 and the lower top rod 27. Furthermore, they are electrically connected to a pair of conductive pressure plates 18, which are symmetrically arranged vertically. When the upper top block 23 moves upward and the lower top rod 27 moves downward, the pressure member 24 first contacts the conductive pressure plate 18, transmitting the clamping force evenly and over a large area to the conductive pressure plate 18. This design not only ensures a uniform distribution of clamping force, preventing damage to the cable, but more importantly, under the action of force, a tight metal contact is formed between the pressure member 24 and the conductive pressure plate 18, and between the conductive pressure plate 18 and the cable, ensuring low impedance of the contact surface and long-term stability of the electrical contact.

[0034] Upper connector 3: Its upper part is slidably disposed in the T-shaped groove of the top component, and can be fixed in a predetermined position by a locking structure such as the limiting rod 6. The conductive pressure plate 18 mentioned above is installed on the inner side of the upper connector 3 (i.e. the side facing the cable).

[0035] Lower connector 17: Its lower part is slidably disposed within the T-shaped groove of the bottom component and can also be locked. The bottom conductive pressure plate 18 is installed on the inner side of the lower connector 17.

[0036] The entire integrated clamping and guiding mechanism is integrated and installed between the upper connector 3 and the lower connector 17, and clamping is achieved through their relative movement.

[0037] To enhance the structural strength and overall rigidity of the connecting components under clamping conditions and prevent deformation or loosening under clamping force and external vibration, both sides of the upper connecting member 3 and the lower connecting member 17 are provided with outwardly extending connecting blocks 20. After the clamping operation is completed, the fixing rod 19 can be used to pass through the corresponding connecting blocks 20 from both sides and detachably connect them together. In this way, the fixing rod 19 firmly locks the upper connecting member 3 and the lower connecting member 17 on both sides, forming a robust overall frame capable of withstanding the tension and vibration from the cable.

[0038] To facilitate the installation and operation of the drive input, the device further includes a separate mounting base 16. This mounting base 16 can be detachably mounted on the bottom surface of the bottom component. The pressing plate 13 is slidably mounted on this mounting base 16. This modular design allows the drive mechanism to be flexibly assembled or disassembled as needed.

[0039] In a preferred design of the mounting base 16, one end has a fixed or operable top pressure plate 12, and the other end has a wire mounting port 14. The top pressure plate 12 is used to drive the pressing plate 13 to slide on the base 16 under external force. The wire mounting port 14 is used to connect the branch lines and draw the current from the main cable.

[0040] To enable safe live-line work or remote operation, this invention also provides a manual operating mechanism. This mechanism includes an insulated mounting rod 8, with a drive wheel 9 at its top and a trigger 10 at its bottom. An operating cable (such as a steel wire rope) is wound around the drive wheel 9, with one end connected to the trigger 10 and the other end connected to a pressure plate 12 on a base. The operator holds the mounting rod 8 from the ground or a safe location, moves the connecting assembly at the top of the device to the overhead cable, and then pulls the trigger 10. Through the operation cable and the drive wheel 9, the pressure plate 12 is remotely pulled or pushed, thereby driving the clamping plate 13 to actuate, ultimately achieving clamping. This greatly improves the safety and convenience of operation.

[0041] Finally, to achieve precise movement and positioning of the connecting component within the T-shaped channel, a drive shaft 5 and a corresponding knob 11 can be installed within the T-shaped guide channel of the frame unit. The operator rotates the knob 11 on the ground, which drives the connecting component to move precisely along the slide rail via the drive shaft 5, adjusting it to the optimal clamping position. Once the position is determined, the connecting component can be locked by inserting a limiting rod 6 into a fixing slot 7 formed on the side wall of the slide rail, preventing displacement during use.

[0042] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
