Description

Technical Field

[0001] This application relates to the field of communication construction, and more particularly to a fixing device for a cable joint. Background Technology

[0002] In power communication systems, 2M coaxial cable serves as a critical transmission medium, widely used in scenarios with extremely high requirements for stability and real-time performance, such as protection channels and automation channels. These cables typically require cable connectors to be fabricated within a cabinet to connect to a digital distribution frame (DDF). Fabricating the cable connector involves connecting the end of the cable to the corresponding connector, usually through soldering.

[0003] However, in actual operation, cables are prone to natural bending after long-term coiled storage, increasing the difficulty of welding the cable ends to the connectors. Currently, when making cable connectors, the cable and connector are usually fixed manually, that is, the cable and connector are held by hand to fix the bent cable ends to the connector position, so as to achieve welding.

[0004] However, due to the limited space in the cabinet and the length of the cabling, the manual fixing of cables and connectors is difficult and inefficient. Furthermore, the welding process can easily burn the operators, making it difficult to guarantee their personal safety. Summary of the Invention

[0005] This application provides a cable connector fixing device for fixing the cable body and connector. It eliminates the need for manual handling, reduces the difficulty of operation, improves work efficiency, reduces the risk of burns to operators, and ensures the personal safety of operators.

[0006] This application provides a cable connector fixing device for a communication cabinet. The cable connector fixing device includes: a support assembly for detachably connecting to the cabinet body of the communication cabinet; a connector clamp installed on the support assembly; the connector clamp having a first clamping space for accommodating the cable connector; a cable clamp installed on the support assembly and spaced apart from the connector clamp along a first direction; the cable clamp having a second clamping space for accommodating the cable wire; the first clamping space and the second clamping space are arranged opposite to each other along the first direction.

[0007] Beneficial Effects: Compared to traditional manual hand-held operation, this solution achieves mechanized fixing instead of manual holding, effectively avoiding many drawbacks of manual operation in confined cabinet spaces. The overall structure is adaptable to on-site construction conditions, significantly improving the standardization of cable joint fabrication processes while reducing the labor intensity of operators and ensuring their personal safety. It has good value for on-site promotion and application. The cable joint fixing device adopts a modular split structure design, with the support component serving as the overall load-bearing base. It is easy to assemble and disassemble and is reusable. Two sets of clamps are arranged in zones with the clamping spaces facing each other, enabling coaxial positioning of the cable joint and the cable body. The clamping structure has a clear division of labor and a reasonable layout, occupying little space overall. It is perfectly adapted to the compact installation environment inside the communication cabinet, with excellent clamping stability and alignment accuracy.

[0008] In one possible implementation, the support assembly includes a first support member; along a first direction, a connector clamp and a cable clamp are spaced apart on the first support member; wherein, along the first direction, the position of the connector clamp on the first support member is adjustable, and / or, the position of the cable clamp on the first support member is adjustable.

[0009] Beneficial effects: The first support provides a unified installation benchmark for various clamps, ensuring the coaxiality of the overall structure; the adjustable clamp position structure design allows for flexible adjustment of the clamp spacing according to different cable specifications, connector sizes, and welding process requirements, greatly improving the versatility and adaptability of the device to working conditions; the adjustment structure is simple and reliable, and stable locking can be achieved after adjustment, without any self-slippage problem.

[0010] In one possible implementation, the support assembly includes a first connector; along a second direction, one end of the first connector is used to connect to the cabinet, and the other end is connected to the first support member; the second direction is perpendicular to the first direction.

[0011] Beneficial effects: The first connector enables the transition between the cabinet and the first support. The orthogonal spatial layout results in uniform stress distribution and high structural rigidity. The entire clamp assembly can be suspended and installed inside the cabinet, effectively avoiding existing cables and equipment inside the cabinet and preventing operational interference. At the same time, it ensures that the first support is in a horizontal state, providing a stable installation benchmark for clamping and welding operations, and further improving the reliability of the device operation.

[0012] In one possible implementation, the connector clamp includes: a first clamping block mounted on a support assembly; a second clamping block movably mounted on the support assembly along a second direction, the second clamping block and the first clamping block being movable relative to each other along the second direction; a first clamping space being formed between the second clamping block and the first clamping block; and a first locking member connected to the first clamping block and the second clamping block, used to drive the first clamping block and the second clamping block closer together to form a clamping state, or to drive the first clamping block and the second clamping block further apart.

[0013] Beneficial effects: The double-clamping structure ensures that the fixed clamping block remains unchanged, while the movable clamping block allows for flexible opening and closing of the clamping space, making it suitable for cable connectors of various shapes and sizes. The clamping force can be continuously adjusted, which not only ensures firm clamping but also avoids squeezing damage to the precision structure of the connector. The clamping and unloading operations are simple, the action logic is clear, and the service life is long.

[0014] In one possible implementation, the first locking member includes a first screw; the first clamping block is provided with a mounting hole, and the second clamping block is provided with a clamping block threaded hole; or, the second clamping block is provided with a mounting hole, and the first clamping block is provided with a clamping block threaded hole; one end of the first screw is rotatably connected to the mounting hole, the first screw passes through and is screwed into the clamping block threaded hole, and the first screw rotates to drive the second clamping block to move closer to or away from the first clamping block in a second direction.

[0015] Beneficial effects: The screw thread transmission structure provides smooth transmission and high adjustment accuracy. At the same time, the thread pair has mechanical self-locking characteristics, which can maintain the locked state for a long time after clamping. It has strong resistance to vibration and external interference. Two hole arrangement forms can be flexibly selected. The parts are general standard parts, which are very convenient for processing, assembly and subsequent maintenance, and the manufacturing cost is low.

[0016] In one possible implementation, the connector clamp includes: an elastic member, which abuts against the first clamping block and the second clamping block in a compressed state along a second direction, and is sleeved on the first screw; and / or a guide member, which extends along the second direction; the first clamping block is provided with a guide hole that extends through the second direction; one end of the guide member in the extending direction is connected to the second clamping block, and the guide member passes through the guide hole.

[0017] Beneficial effects: The elastic element can compensate for the thread fit clearance and buffer the rigid impact when the clamping block closes. At the same time, it assists in the reset of the clamping block, which plays a role in protecting the joint and improving the smoothness of operation. The guide element and the guide hole form a linear guide mechanism, which constrains the movement trajectory of the movable clamping block, prevents the clamping block from deflecting or tilting, ensures the stability of the clamping posture, and further improves the alignment accuracy of the joint clamping and the stability of the structural operation.

[0018] In one possible implementation, the cable clamp includes: a base mounted on a support assembly; a sleeve connected to the base; the sleeve having an inner cavity extending through the sleeve in a first direction and forming a second clamping space; a threaded hole on the side wall of the sleeve extending radially along the sleeve and communicating between the outside of the sleeve and the inner cavity; and a second locking member including a second screw; the second screw passing through and screwed into the threaded hole of the sleeve, and at least a portion of the second screw being located within the second clamping space.

[0019] Beneficial effects: The sleeve-type structure can wrap the cable body in all directions, effectively correcting the natural bending deformation of the cable and keeping the cable body straight; the radial top-tightening locking structure is easy to operate, can be adapted to cables of different diameters, and has a good circumferential limiting effect, which can prevent the cable from rotating or moving; the overall structure is compact and has no protruding sharp parts, which can avoid scratching other circuits inside the cabinet and ensure high safety.

[0020] In one possible implementation, the base includes an arc-shaped support portion with a strip-shaped hole extending along a first direction and penetrating the convex and concave surfaces of the arc-shaped support portion; the cable clamp also includes a third screw and a fastening nut; a sleeve is disposed on the concave surface of the arc-shaped support portion; the third screw passes through the strip-shaped hole, with one end of the third screw connected to the sleeve and the other end threadedly connected to the fastening nut; when the fastening nut is tightened, it is suitable for fixing the sleeve to the concave surface.

[0021] Beneficial effects: The arc-shaped support fits snugly against the outer wall of the sleeve, providing uniform force and strong support stability, effectively preventing the sleeve from flipping or shifting; the strip-shaped hole, together with the screw and nut, forms a sliding adjustment mechanism, enabling stepless fine adjustment of the sleeve's axial position, accurately calibrating the coaxiality of the cable and connector, optimizing the welding and connection effect, and the adjustment structure can be operated by hand without additional tools, making it highly practical.

[0022] In one possible implementation, the cable connector fixing device further includes: an image acquisition device mounted on the support assembly; and along the second direction, the image acquisition device is located on one side of the connector clamp and the cable clamp; the image acquisition device is used to acquire welding image information at the connection between the connector and the cable body; an image display; and a controller electrically connected to the image acquisition device and the image display, the controller being configured to acquire the welding image information acquired by the image acquisition device and transmit it to the image display for display.

[0023] Beneficial effects: The addition of image acquisition and display components enables visual monitoring of welding points, overcoming the shortcomings of insufficient accuracy and limited line of sight for human eyes in observing tiny welding points; the side-mounted installation layout does not obstruct the welding operation space, and the operation and monitoring do not interfere with each other, and can present the welding point status in real time, making it easier for operators and supervisors to detect welding defects in a timely manner and reduce the production of defective products.

[0024] In one possible implementation, the controller includes a processor and a memory. The processor is electrically connected to an image acquisition device, an image display, and the memory. The memory stores preset welding image information. The processor is configured to acquire welding image information acquired by the image acquisition device and transmit it to the image display for display. The processor is also configured to generate welding quality inspection information based on the welding image information acquired by the image acquisition device and the preset welding image information, and send the welding quality inspection information to the image display for display.

[0025] Beneficial effects: The cable joint fixing device of this application introduces machine vision intelligent comparison technology, which realizes automated quality inspection based on pre-stored standard images. The inspection results are objective and consistent, and the limitations of human experience judgment are eliminated. It can automatically generate quality inspection information and display it in real time, while retaining image data to realize quality traceability, improve the level of construction standardization and quality control, reduce the cost of manual quality inspection, and further improve the overall operation efficiency.

[0026] The cable connector fixing device provided in this application embodiment can be detachably fixed to the communication cabinet via a support assembly. The connector clamp and cable clamp respectively hold the cable connector and the cable body, aligning them relative to each other along a first direction, allowing for stable fixing without manual handling. This device has a simple structure, is easy to operate, and is suitable for the confined space of the cabinet, effectively reducing the difficulty of operation, improving welding efficiency, and avoiding the risk of welding burns, thus ensuring operational safety.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0045] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0049] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] First, let me explain the terms used in this application:

[0051] 2M Coaxial Cable: In the power communication industry, SYV series solid polyethylene insulated radio frequency coaxial cables are conventionally referred to as 2M coaxial cables. These cables feature a coaxial structure design and possess outstanding characteristics such as good impedance matching, low signal attenuation, strong resistance to external electromagnetic interference, and wide transmission bandwidth. They are the fundamental transmission carrier for core services such as power dispatching, relay protection, automated remote control, and voice and data private networks. Their nominal transmission rate is compatible with the 2Mbit / s digital signal transmission standard, hence the name 2M coaxial cable. They are widely used in communication rooms, power cabinets, outdoor communication sites, and other scenarios, and are also the main processing target of this device. The cable consists of four layers: an inner conductor, insulating medium, outer shielding layer, and outer sheath. It has a compact structure and moderate flexibility; however, it is prone to plastic bending deformation after long-term coiling and storage, which is the main reason why special fixing fixtures are required for on-site welding processing.

[0052] BNC connector: Short for Bayonet Neill-Concelman, it is one of the most widely used standard 2M coaxial cable interface specifications in the communications field. This interface uses a bayonet-type quick-locking structure, making insertion and removal convenient and fast. After connection, it provides reliable contact and strong vibration resistance, effectively preventing transmission interruptions caused by loose signal interfaces. BNC connectors are mostly cylindrical in shape and are suitable for crimping and soldering the ends of standard SYV series 2M coaxial cables. They are commonly used in digital patch panels, communication switches, RF equipment, and other terminals, and are also the mainstream interface type for cable connector fabrication in communication cabinets.

[0053] L9 connector: Also known as a 1.6 / 5.6 coaxial connector, it is a standard communication interface type used in domestic power and private network communication systems, and is also a connector for 2M coaxial cables. This interface features precise dimensions, stable electrical performance, and impedance parameters that strictly match the 2M digital transmission link standard. Compared to general-purpose interfaces, it offers superior mechanical protection and long-term operational stability. It is primarily used in core business scenarios with extremely high signal transmission reliability requirements, such as power relay protection channels and power grid automation communication. The L9 connector has a regular shape and a small soldering area, requiring high alignment accuracy between the cable and the connector, and heavily relies on this clamping device for positioning.

[0054] CC3 / C3 Port: The CC3 (also known as C3) interface is another dedicated 2M coaxial cable interface specification in the communications industry, belonging to the compact RF coaxial connector category. This interface is small in size and occupies little space for cabling, making it suitable for high-density cable routing within equipment racks. It is widely used in small and medium-sized communication cabinets and integrated wiring devices. The internal core of the CC3 / C3 connector is delicate, resulting in a low tolerance for soldering errors. Manual handling easily leads to misalignment and poor soldering. Adapting this device for mechanized fixing significantly improves the connector processing pass rate.

[0055] DDF, short for Digital Distribution Frame, is a core integrated cabling device in communication equipment rooms and power communication cabinets used for aggregating, switching, and managing digital communication lines. The device panel integrates numerous standardized interfaces specifically responsible for the access, patching, branching, and maintenance management of 2M coaxial cable lines. All fabricated 2M coaxial cable connectors must ultimately be plugged into the corresponding interfaces on the DDF device to establish a complete digital signal transmission link. DDF devices are typically densely packed inside cabinets, resulting in limited operating space and presenting significant environmental challenges for on-site cable connector fabrication.

[0056] HDMI: High-Definition Multimedia Interface, is a standardized digital audio and video transmission interface. In this device, this interface is mainly used for wired signal transmission between the image acquisition unit and the image display and controller. It features high transmission bandwidth, high image clarity, low signal latency, and synchronous audio and video transmission, enabling real-time, lossless transmission of high-definition images of the welding area to the display terminal, ensuring smooth and clear visual monitoring.

[0057] USB: Short for Universal Serial Bus, it is a universal data transmission and power supply interface in the field of electronic devices. In this cable connector fixing device, the USB interface mainly performs two functions: first, it provides stable DC power to electrical components such as image acquisition devices, controllers, and displays, and is compatible with various power supply methods such as built-in batteries, external USB power supplies in the computer room, and mobile power supplies; second, it assists in the transmission of equipment operation data, quality inspection logs, and image archive files. The interface has strong versatility, simple wiring, and facilitates on-site equipment wiring and power supply.

[0058] TFT, short for Thin Film Transistor, is an active switching device fabricated using semiconductor technology. TFT displays, driven by this device, are the mainstream display terminals in current industrial equipment and consumer electronics. TFT displays rely on independent thin-film transistors behind each pixel for precise driving, offering advantages such as fast screen response, high color fidelity, wide viewing angles, and a thin and lightweight structure. This device prioritizes the use of a TFT display for its image display, enabling clear and real-time display of magnified images of welding points and intelligent quality inspection results, suitable for the long-term continuous operation requirements of computer rooms.

[0059] In the power communication system, the communication network is the core nerve center for ensuring the safe and stable operation of the power grid, realizing remote dispatch and control, and handling emergency faults. 2M coaxial cable, as the mainstream medium for digital signal transmission, has long undertaken a series of high-priority, high-reliability core services, including power grid relay protection channels, dispatch automation channels, remote control information channels, signal channels for stability devices, as well as voice communication and dedicated data networks. These services are directly related to the normal power supply and rapid fault location and isolation of the regional power grid. Once the signal transmission link is interrupted, has poor contact, or experiences excessive signal attenuation, it can lead to regional dispatch failures and automation equipment going offline, or even cause relay protection malfunctions or failures to operate, posing significant safety hazards and economic losses to the power system. Therefore, the processing and manufacturing quality and connection stability of 2M coaxial cable and its matching connectors are key aspects to be controlled during on-site construction, operation, and maintenance of power communication systems.

[0060] Firstly, in the actual production of 2M coaxial cables, due to industry-standard requirements for warehousing management, long-distance transportation, on-site transfer, and site organization, brand-new, spare, and reusable 2M coaxial cables are all stored and handled in a coiled manner. The cable is under continuous bending stress for a long period, causing irreversible plastic deformation in the internal copper conductor, insulation layer, shielding mesh, and outer sheath. After the installation personnel complete the cable laying according to the wiring plan and remove the outer sheath, metal shielding layer, and insulation layer at the ends according to process standards, the exposed cable ends will exhibit obvious natural bending and warping, unable to maintain a horizontal and straight posture. When welding joints, additional tools or on-site clamps are needed to fix them in place to ensure the solder joints face upwards for easy soldering. Otherwise, without fixation, the joints will tend to bend and are difficult to control. Without the constraint of dedicated tooling, the bent wire always tends to spring back, which not only makes it impossible to accurately align the joint welding position, but also easily leads to quality defects such as solder joint misalignment, uneven solder accumulation, and insufficient contact between the copper core and the joint, significantly increasing the defect rate of joint manufacturing.

[0061] Secondly, in daily operations, the laying scenarios for power and communication cables are complex and diverse. Besides internal cabling within equipment rooms, there are also common situations involving cross-equipment link construction, underground cable trench pre-laying, wall-penetrating and conduit installation, and high-altitude cable tray routing. If cable joints are pre-fabricated before laying begins, the protruding joint structure is highly susceptible to impacts, pressure, and scratches during conduit installation, dragging, trench laying, and wall penetration, leading to joint deformation, solder joint detachment, and damage to the internal core, directly rendering the entire cable unusable. Furthermore, pre-fabricating joints significantly increases the difficulty of cable routing and cannot adapt to complex laying paths. Therefore, considering industry construction standards and actual site conditions, 2M cable joints must be fabricated on-site at the work terminal after the overall cable laying, management, and positioning are completed. As the convergence terminal and transfer node for all 2M coaxial cable lines, the welding, assembly, and debugging of cable joints inside the communication cabinet have become one of the most frequent and labor-intensive tasks in the daily construction, renovation, expansion, and emergency repair of power communication systems. The large-scale, routine joint fabrication work also places higher demands on the practicality, convenience, and safety of the tools used.

[0062] However, the limited cable length and internal space of the cabinet often make it difficult to secure cable connectors and cables using conventional tools or field clamps, thus making the fabrication of 2M cable connectors inside the cabinet quite challenging. Standard communication cabinets are integrated, enclosed enclosures that house digital patch panels, switches, power supplies, cooling systems, cable management racks, cable trays, and other equipment and accessories. Their compact layout and narrow working surface, coupled with the short excess length of some cables, further restrict the scope of work.

[0063] Commonly used bench vises, small clamps, and clamping brackets on the market are generally too large, inconvenient to install, and cannot be adapted to the small space of the server rack, making them difficult to use normally in such restricted environments.

[0064] In on-site operations, the industry has long relied on traditional manual fixing methods, where operators manually hold the cable and connector and weld them together. However, this method is difficult, inefficient, and requires a certain level of experience, making it hard to learn quickly. Novice operators, due to insufficient hand stability and uneven force control, are prone to problems such as misalignment, incomplete welding, and incorrect welding, requiring extensive practical experience to reach a qualified level. Even experienced operators experience hand and arm muscle fatigue and soreness from holding the cable and connector suspended in the air for extended periods, further reducing clamping stability and operational continuity.

[0065] Furthermore, the mainstream process for cable joint processing is soldering with an electric soldering iron. During the soldering process, both the soldering iron and the molten solder are at high temperatures. The interior of the cabinet has many obstructions to the view and very little space for hand movement. Operators' hands are in close proximity to the high-temperature work area, making them susceptible to burns and compromising their safety. In addition, manual hand-held operation carries the risk of accidentally pulling on existing cables or disturbing existing wiring within the cabinet, which can easily cause temporary interruptions to communication services and trigger additional maintenance failures.

[0066] Considering the multiple pain points mentioned above, the traditional operation mode can no longer meet the current development requirements of standardized construction, high-efficiency operation, high-safety management and control, and high-quality delivery in power and communication engineering.

[0067] Based on this, this application provides a cable connector fixing device for fixing the cable body and the connector. It eliminates the need for manual handling, reduces the difficulty of operation, improves work efficiency, reduces the risk of burns to operators, and ensures the personal safety of operators.

[0068] This device features a specialized structural design for core operating conditions such as confined spaces in communication cabinets, cable bending and deformation, adaptation to multiple connector specifications, and high-frequency on-site operations. It can completely replace traditional manual hand-held operations while also considering versatility, portability, and reusability. It effectively standardizes on-site construction processes, improves the overall processing quality of cable joints, and possesses extremely high engineering application and industry promotion value. The following detailed description of the cable joint fixing device provided in the embodiments of this application is based on the accompanying drawings. The following embodiments are used to explain this application, not to limit it.

[0069] This application provides a cable connector fixing device for positioning and fixing the cable connector and cable body inside a communication cabinet, facilitating welding operations. Wherein, Figure 1 and Figure 2 A schematic diagram illustrating an application scenario of the cable connector fixing device of this application is shown.

[0070] Specifically, such as Figure 3 As shown, Figure 3 A schematic diagram of the overall structure of the fixing device of this application is shown. The fixing device 2 includes a support assembly 21, a connector clamp 22, and a cable clamp 23. Optionally, the fixing device 2 may also include an image acquisition unit 24, an image display, a controller, and a power supply 25.

[0071] More specifically, the support assembly 21 is used for detachable connection to the cabinet 1 of the communication cabinet. The connection between the support assembly 21 and the cabinet 1 can be achieved by bolt locking, elastic buckle, or magnetic fixation, which is convenient for disassembly and assembly and reliable for connection.

[0072] Furthermore, both the connector clamp 22 and the cable clamp 23 are mounted on the support assembly 21, and are spaced apart along the first direction X. Understandably, the support assembly 21 provides a supporting base for the connector clamp 22 and the cable clamp 23 within the cabinet 1. The connector clamp 22 is used to clamp and fix the cable connector, and the cable clamp 23 is used to clamp and fix the cable body.

[0073] Furthermore, the connector clamp 22 has a first clamping space 220 for accommodating the cable connector. The cable clamp 23 has a second clamping space 230 for accommodating the cable body. Along the first direction X, the first clamping space 220 and the second clamping space 230 are arranged opposite to each other, so that the cable connector and the end of the cable body are precisely aligned.

[0074] Along the first direction X, the first clamping space 220 and the second clamping space 230 are arranged opposite to each other. After the cable clamp 23 and the connector clamp 22 clamp and fix the cable body and the connector respectively, they can form a coaxial constraint on the cable body and the connector, which facilitates the precise connection of the welding joint of the cable body and the connector, facilitates the subsequent welding operation, improves welding efficiency, and ensures welding quality.

[0075] In actual use, the entire fixing device 2 is installed in the cabinet by the support component 21, the connector is fixed on the connector clamp 22, the cable is fixed on the cable clamp 23, and the end of the cable is connected to the welding point of the connector, and soldering is performed at the connection point.

[0076] In this embodiment, the fixing device 2 is detachably fixed to the communication cabinet via the support component 21. The connector clamp 22 and the cable clamp 23 respectively clamp the cable connector and the cable body, aligning them relative to each other along the first direction X, allowing for stable fixing without manual handling. This device has a simple structure, is easy to operate, and is suitable for the confined space of the cabinet, effectively reducing the difficulty of operation, improving welding efficiency, and avoiding the risk of welding burns, thus ensuring operational safety.

[0077] Understandably, the cable connector fixing device 2 provided in this application is not limited to the fabrication of 2M coaxial cable connectors. Through the modular structural design of the support component 21, connector clamp 22, and cable clamp 23, the device can adapt to the fixing and welding operations of connectors for communication cables and power cables of different specifications and types, such as various radio frequency coaxial cables, control cables, signal cables, and multi-core cables.

[0078] Furthermore, the support assembly 21 includes a first support member 211, and along the first direction X, a connector clamp 22 and a cable clamp 23 are spaced apart on the first support member 211.

[0079] Optionally, the support assembly 21 includes a first support member 211. The first support member 211 may be plate-shaped, specifically a rectangular metal profile or sheet metal.

[0080] Optionally, the support assembly 21 includes at least two first support members 211, which are arranged side by side and connected along the first direction X.

[0081] like Figure 3 In the illustrated embodiment, the support assembly 21 includes two first support members 211. Each first support member 211 includes a support plate 2111 and two first connecting plates 2112. Along a first direction X, the two first connecting plates 2112 are respectively connected to both ends of the support plate 2111, and the support plate 2111 and the first connecting plates 2112 form an angle. Exemplarily, the support plate 2111 and the first connecting plates 2112 can be perpendicular to each other. This arrangement facilitates the interconnection between adjacent first support members 211.

[0082] It should be noted that when the support assembly 21 includes at least two first support members 211, the connector clamp 22 and the cable clamp 23 can be spaced apart on the same first support member 211, or they can be respectively installed on two adjacent first support members 211. Providing at least two first support members 211 facilitates flexible adaptation to differences in the width and depth of different cabinet interiors. By increasing or decreasing the number of first support members 211, the operating span requirements of different cable specifications can be accommodated, thereby improving the field adaptability and versatility of the fixing device 2.

[0083] Understandably, the support component 21 may also include three, four, five or other numbers of first support members 211.

[0084] In some embodiments, the position of the connector clamp 22 on the first support member 211 along the first direction X can be adjusted so as to flexibly adjust the distance between the connector clamp 22 and the cable clamp 23, as well as the distance between the connector end face and the welding area, to adapt to different process requirements. At the same time, the arrangement position can be optimized according to the site space and wiring conditions to improve the site adaptability and versatility of the fixing device 2.

[0085] Based on conventional mechanical adjustment structure design concepts in this field, this part adopts a mature structure combining sliding fit and threaded locking. This structure features controllable adjustment stroke, high positioning accuracy, strong self-locking capability, and anti-vibration slippage, meeting the operating conditions required for communication equipment in the field. During actual assembly, the adjustment range can be preset according to parameters such as the axial dimension of the cable connector and the length reserved for welding processes, further improving the standardization of operations. Simultaneously, this position adjustment structure is integrated entirely onto the surface of the first support component 211, without any protruding or complex components, thus not occupying additional operating space in the cabinet. Its compact structure allows for stable operation in the environment of high vibration and cable interference within the cabinet for extended periods, with low component wear rates and minimal maintenance and repair workload.

[0086] Specifically, the bottom of the connector clamp 22 is provided with a sliding connection structure and a locking structure, and the first support member 211 is provided with a guide structure. The sliding connection structure at the bottom of the connector clamp 22 cooperates with the guide structure to realize the position movement of the connector clamp 22 along the first direction X. The locking structure of the connector clamp 22 can reliably lock the connector clamp 22 at any position.

[0087] For example, such as Figure 3 As shown, the guide structure on the first support member 211 can be a groove 2113 extending along the first direction X. The sliding connection structure of the connector clamp 22 can be a bolt, and the locking structure can be a nut. The bolt passes through the groove 2113, and the nut is screwed to the bolt. When the nut is tightened, the connector clamp 22 can be locked and fixed at any position in the groove 2113. The structure is simple and the manufacturing cost is low.

[0088] The sliding locking structure of the aforementioned groove 2113 in conjunction with the bolt and nut is a standard structure commonly used in the mechanical field. Components are readily available and highly interchangeable; even if components are damaged on-site, replacements can be completed quickly without affecting the construction progress. The groove 2113 is integrally milled with a smooth inner wall, resulting in low resistance during sliding. Simultaneously, the sidewalls of the groove 2113 have a limiting function, restricting radial displacement of the bolt and ensuring that the movement trajectory of the joint clamp 22 always extends along the first direction X. Nuts can be selected from types such as lock nuts and wing nuts. Wing nuts can be tightened and loosened by hand without external tools, further simplifying on-site operations and meeting the needs of rapid construction in computer rooms.

[0089] For example, the guide structure on the first support member 211 can also be a guide rail extending along the first direction X. The sliding connection structure of the connector clamp 22 can be a slider, and the locking structure can be a screw. The slider slides in cooperation with the guide rail, and the set screw passes through the side wall of the slider and can press against the guide rail, so as to lock and fix the connector clamp 22 at any position on the guide rail, with smooth sliding and stable positioning.

[0090] Employing a guide rail and slider combination, this design offers higher sliding precision compared to a chute structure, making it suitable for high-precision welding applications requiring strict coaxiality between cables and connectors. The guide rail can be linear or dovetail type, providing stronger overall load-bearing capacity and withstanding lateral tension from cables as well as alternating forces from repeated loading and unloading, resulting in a longer service life. The side-wall tightening set screw locking method features a large contact area, ensuring no relative movement between the slider and guide rail after tightening, providing excellent anti-displacement performance and meeting the requirements of long-term continuous operation.

[0091] In some embodiments, the position of the cable clamp 23 on the first support 211 along the first direction X can be adjusted so as to flexibly adjust the distance between the connector clamp 22 and the cable clamp 23, as well as the length of the cable extending into the welding area, to adapt to different process requirements and further improve the on-site adaptability and versatility of the fixing device 2.

[0092] The adjustable position design of the cable clamp 23, together with the adjustment structure of the connector clamp 22, forms a complete system. Their adjustment logic and operation methods are unified, facilitating quick familiarization of the operation process by operators and reducing learning costs. For cables with different insulation stripping lengths and diameters, operators can independently adjust the position of the cable clamp 23 to precisely control the exposed length of the cable, ensuring that the welding area dimensions meet industry construction standards and guaranteeing standardization in connector fabrication from a tooling perspective. This adjustment structure also possesses excellent environmental adaptability, resisting vibrations generated by the operation of equipment inside the cabinet and effectively preventing the cable clamp 23 from slipping during operation.

[0093] Specifically, the bottom of the cable clamp 23 may also be provided with a sliding connection structure and a locking structure, and the first support member 211 is provided with the aforementioned guide structure. The sliding connection structure at the bottom of the cable clamp 23 cooperates with the guide structure to realize the positional movement of the cable clamp 23 along the first direction X. The locking structure of the cable clamp 23 can reliably lock the cable clamp 23 at any position. In this embodiment, the arrangement of the sliding connection structure and locking structure of the cable clamp 23 is similar to that of the connector clamp 22, and will not be described again here.

[0094] Alternatively, in some embodiments, the positions of the connector clamp 22 and the cable clamp 23 on the first support member 211 are adjustable along the first direction X. In this embodiment, both the connector clamp 22 and the cable clamp 23 adopt independent sliding connection structures and locking structures, and respectively cooperate with the guide structure of the first support member 211. This arrangement allows for bidirectional linkage or independent fine-tuning of the connector clamp 22 and the cable clamp 23, with the adjustment process not interfering with each other, further improving the flexibility of the fixing device 2 and adapting to more complex wiring scenarios. In this embodiment, the arrangement of the sliding connection structure, locking structure, and guide structure is similar to that in the above embodiments, and will not be described again here.

[0095] Two sets of independent adjustable structures work together to achieve stepless adjustment of the distance between the two clamps, enabling the device to handle complex working conditions such as insufficient cable length, narrow spaces, and assembly of irregularly shaped connectors within the cabinet. The two adjustment mechanisms operate independently; a failure in one mechanism will not affect the normal operation of the other, resulting in a higher overall fault tolerance. Simultaneously, the dual adjustable structure allows for multi-point alignment calibration, maximizing the coaxiality of the cable connector and the cable body, effectively reducing the probability of welding defects such as misaligned soldering and incorrect soldering, and improving the finished product qualification rate.

[0096] Furthermore, in some embodiments, the support component 21 further includes a first connector 212. Along the second direction Y, one end of the first connector 212 is connected to the cabinet 1, and the other end is connected to the first support component 211. The second direction Y is perpendicular to the first direction X. With this configuration, the first connector 212 can suspend and fix the first support component 211 within the cabinet 1, achieving stable installation and flexible layout of the entire device within the cabinet, ensuring the horizontal and vertical accuracy of the fixture installation reference, avoiding interference with existing wiring within the cabinet, and providing a stable and independent installation platform for precise clamping and welding of connectors and cables.

[0097] The first connector 212, serving as a transitional load-bearing component, is manufactured using an integrated molding process. Its overall structure boasts high rigidity and minimal deformation, enabling stable load transfer and ensuring the first support component 211 remains horizontal at all times. This avoids alignment deviations caused by fixture tilting from the installation datum perspective. The spatial layout, with the first and second directions perpendicular, represents a classic orthogonal layout in the field of mechanical tooling, resulting in uniform stress distribution and excellent mechanical performance. Simultaneously, the suspended installation structure maintains a safe distance between the fixture components and the cabinet base and side walls. During operation, solder residue and high-temperature fumes can naturally dissipate, preventing accumulation on the tooling surface and facilitating subsequent cleaning and maintenance. It also avoids damage to the equipment caused by high-temperature components contacting the cabinet. This first connector 212 serves a dual purpose of installation positioning and spatial avoidance, perfectly adapting to the dense cable and complex component layout characteristics inside communication cabinets.

[0098] Specifically, such as Figure 3 As shown, the first connecting member 212 may include a second connecting plate 2121 and a third connecting plate 2122, which are connected to each other at an angle. Preferably, the first connecting member 212 is a bent metal component, and the second connecting plate 2121 and the third connecting plate 2122 are formed by bending. The second connecting plate 2121 and the third connecting plate 2122 are in an "L" shape. The "L" shaped bent structure does not require additional welding splicing, has strong overall integrity, and its torsional and bending resistance is better than that of a split welded structure. It will not crack or deform even under long-term static load and small vibration.

[0099] The first connector 212 can be made of materials such as aluminum alloy, cold-rolled steel plate, or stainless steel. Aluminum alloy is lightweight and corrosion-resistant, making it easy to transport and disassemble the entire device. Stainless steel has excellent rust resistance and is suitable for use in humid environments such as computer rooms. The material selection can be flexibly adjusted according to the on-site working conditions. The bends of the first connector 212 are rounded to eliminate stress concentration points and further extend the service life of the component. At the same time, the rounded surface can prevent scratching the insulation layer of the cables inside the cabinet.

[0100] The second connecting plate 2121 is used to connect to the cabinet body 1 of the server rack, such as by bolt locking, elastic buckle, or magnetic fixation. For example,... Figure 1 and Figure 2 As shown, each of the four corners of the cabinet is equipped with a column 11, and multiple bolt connection holes are spaced apart along the height direction of the column 11. Correspondingly, multiple bolt connection holes are also provided on the second connecting plate 2121 along the third direction Z. The second connecting plate 2121 and the column 11 are detachably connected through the bolt connection holes and bolts. The third direction Z is perpendicular to both the first direction X and the second direction Y. When the fixing device 2 is installed in the cabinet, the third direction Z corresponds to the height direction of the cabinet, which allows the first support member 211 to be set horizontally, providing a horizontal reference plane for the fabrication of the cable connector.

[0101] The design with multiple bolt connection holes allows operators to freely choose installation points according to the different working areas inside the cabinet, enabling the position of the fixing device 2 in the cabinet height direction to adapt to cable connector welding operations of different heights. The bolt connection method is reliable, easy to assemble and disassemble, and the contact surfaces fit tightly after connection without any looseness or gaps. Elastic clips and magnetic connections are suitable for scenarios requiring frequent assembly and disassembly or temporary operations, offering faster assembly and disassembly speeds and further enhancing the flexibility of the tooling. These three connection methods can be used individually or in combination, enriching the installation options of the device.

[0102] The third connecting plate 2122 is used to connect with the first support member 211. Specifically, the first support member 211 includes the aforementioned first connecting plate 2112, and the third connecting plate 2122 is connected to the aforementioned first connecting plate 2112, such as by bolt connection, welding, etc. For example, the third connecting plate 2122 is provided with a plurality of bolt connection holes at intervals, and the first connecting plate 2112 is provided with a corresponding plurality of bolt connection holes. The third connecting plate 2122 and the first connecting plate 2112 are connected through the bolt connection holes and bolts.

[0103] The bolted connection facilitates the disassembly and storage of the first support member 211 and the first connecting member 212. When the device is not in use, it can be disassembled into individual components, reducing storage space occupation and meeting the requirements for equipment storage and management in the computer room. The welded connection is suitable for long-term fixed use conditions, with higher connection strength, no relative displacement between components, and better reference stability. Multiple sets of alignment bolt holes allow for fine adjustment of the position of the first support member 211 in the second direction Y, further optimizing the overall spatial layout of the fixture.

[0104] For example, the first connector 212 may also include a reinforcing plate 2123, which is connected to both the second connecting plate 2121 and the third connecting plate 2122 to improve the bending and torsional resistance of the first connector 212.

[0105] The reinforcing plate 2123 forms a triangular support structure. Utilizing the strong stability of the triangular structure, it significantly improves the overall structural strength of the "L"-shaped first connector 212, effectively offsetting the bending and torque caused by the weight of the clamps and cables, as well as the clamping force, preventing bending deformation of the connecting plate. The reinforcing plate 2123 can be fixed to the second connecting plate 2121 and the third connecting plate 2122 by welding, riveting, or other methods. The assembly process is simple, and the addition does not affect the original disassembly and assembly performance of the device. It is a conventional optimization method to improve the load-bearing capacity of thin-walled metal components and is widely used in the field of tooling equipment.

[0106] Furthermore, in some embodiments, such as Figure 4 As shown, Figure 4 The specific structure of the connector clamp 22 is shown. The connector clamp 22 includes a first clamping block 221, a second clamping block 222, and a first locking member 223. The first clamping block 221 is mounted on the support assembly 21, specifically on the first support member 211. The second clamping block 222 is movably mounted on the support assembly 21 along the second direction Y, and the second clamping block 222 and the first clamping block 221 are movable relative to each other along the second direction Y, forming the aforementioned first clamping space 220 between the second clamping block 222 and the first clamping block 221. The first locking member 223 is connected to the first clamping block 221 and the second clamping block 222, and is used to move the first clamping block 221 and the second clamping block 222 closer together to form a clamping state, or to move the first clamping block 221 and the second clamping block 222 away from each other.

[0107] In this embodiment, the first clamping block 221 is rigidly fixed to the support component 21 to ensure reference stability; the second clamping block 222 can move smoothly along the second direction Y, and the movement trajectory is controllable. The opposing surfaces of the two clamping blocks can be curved surfaces, grooved surfaces, or flat surfaces that adapt to the shape of the connector, together forming the first clamping space 220. Since the second clamping block 222 and the first clamping block 221 can move relative to each other along the second direction Y, the size of the first clamping space 220 is adjustable to accommodate various standard connector specifications, such as BNC, L9, and CC3 type connectors, etc., providing strong versatility and stable and reliable clamping.

[0108] The clamping space is infinitely adjustable, covering mainstream connector types for communication equipment rooms. Multiple connectors can be clamped without changing fixtures, reducing tooling quantity and equipment investment for construction units. The contact surface between the second clamping block 222 and the first clamping block 221 can be treated with anti-slip textures and anti-slip pads to increase the coefficient of friction with the connector's outer wall, preventing circumferential rotation or axial movement of the connector under welding stress, further improving clamping stability. Contour structures such as curved and grooved surfaces enable rapid connector positioning, eliminating the need for repeated calibration by operators and improving work efficiency.

[0109] The first locking component 223 can employ a screw locking structure, an eccentric wheel locking structure, or a quick-clamp structure. Multiple locking structures can be flexibly selected based on the operational scenario: the screw locking structure offers high adjustment precision and controllable clamping force, suitable for precision welding operations; the eccentric wheel locking structure boasts fast opening and closing speeds, suitable for high-frequency, high-volume joint fabrication; and the quick-clamp structure requires less effort to operate and reduces fatigue during extended use. All three structures are commonly used and mature in the industrial fixture field, with low technical difficulty in implementation and a wide range of component selection options.

[0110] Specifically, in some embodiments, the first locking member 223 is a screw locking structure, which includes a first screw 2231, a first clamping block 221 with a mounting hole 224, and a second clamping block 222 with a clamping block threaded hole 225. One end of the first screw 2231 is rotatably connected to the mounting hole 224, and the first screw 2231 passes through and is screwed into the clamping block threaded hole 225. The rotation of the first screw 2231 drives the second clamping block 222 to move closer to or away from the first clamping block 221 along the second direction Y. This threaded locking structure can precisely control the clamping force, avoiding damage to the joint due to excessive tightness or slippage due to excessive looseness. It is easy to operate without tools, has a stable clamping state, and is not prone to loosening after long-term use.

[0111] Threaded drives possess the core advantages of high precision and strong self-locking. The number of turns of the screw corresponds linearly to the movement distance of the clamping block. Operators can precisely control the clamping force based on the joint material and shell hardness, preventing problems such as excessive clamping force causing cracking or insufficient clamping force causing slippage. The mechanical self-locking characteristic of the threaded pair allows it to maintain a permanent clamping state without external force intervention. Even when subjected to contact during welding or cable tension, the clamping block will not loosen on its own, significantly improving operational safety and stability. Both the screw and the threaded hole use standard thread specifications, simplifying processing and ensuring good interchangeability. If stripping or wear occurs after long-term use, the screw or clamping block can be replaced individually, making maintenance convenient.

[0112] Or, in Figure 4 In the illustrated embodiment, the second clamping block 222 is provided with the aforementioned mounting hole 224, and the first clamping block 221 is provided with the aforementioned clamping block threaded hole 225. One end of the first screw 2231 is rotatably connected to the mounting hole 224, and the first screw 2231 passes through and is screwed into the clamping block threaded hole 225. When the first screw 2231 rotates, since the first clamping block 221 is fixed to the first support member 211 and cannot move along the second direction Y, the second clamping block 222 can move along the second direction Y towards or away from the first clamping block 221 under the drive of the first screw 2231.

[0113] The two hole arrangement schemes are structurally identical, differing only in assembly location. During production and assembly, the choice can be flexibly made based on processing technology and assembly space, improving the process adaptability of the device. Neither scheme alters the movement or performance of the clamping blocks, and the operation method is standardized, without increasing the difficulty of use.

[0114] exist Figure 4 In the illustrated embodiment, the first locking member 223 further includes an end cap, which is connected to one end of the first screw 2231 and located on the side of the second clamping block 222 away from the first clamping block 221. During clamping operations, the operator can rotate the first screw 2231 by holding the end cap.

[0115] The end cap can be equipped with a round handwheel or a wing-shaped end cap for easy operation, eliminating the need for traditional wrenches and enabling tool-free operation, thus simplifying the on-site process. The end cap is secured to the first screw using an interference fit or threaded connection, ensuring a firm connection and preventing slippage or detachment during rotation. The end cap surface can be knurled for improved grip, increasing friction and allowing for smooth screw rotation even with hands covered in solder paste or dust.

[0116] In some embodiments, the connector clamp 22 further includes a second connector 229, which is connected to the first clamping block 221 and fixes the first clamping block 221 to the first support member 211.

[0117] The second connector 229 serves as a transfer and installation component for the connector clamp 22, enabling modular assembly of the clamp block and the first support 211. This facilitates the overall disassembly, maintenance, and replacement of the connector clamp 22. When it is necessary to replace clamp blocks of different specifications, the entire connector clamp 22 can be disassembled and replaced without disassembling small internal parts, thus improving tooling changeover efficiency.

[0118] like Figure 4 As shown, the second connector 229 includes a mounting section and a connecting section that are perpendicular to each other, specifically in the form of an "L"-shaped plate structure. The connecting section connects to the side of the first clamping block 221, and the mounting section connects to the sliding groove 2113 on the first support member 211. The "L"-shaped plate structure occupies little space and cleverly utilizes the vertical space between the side of the clamping block and the surface of the support member, resulting in a compact layout. The two perpendicular sections can achieve connection and fixation in different directions, with clear force layering and strong structural stability.

[0119] More specifically, the mounting section may have a strip-shaped mounting hole extending along the first direction X. This strip-shaped mounting hole engages with a sliding groove 2113 on the first support member 211 via a fastener, thereby adjusting and locking the position of the connector clamp 22 on the first support member 211. A threaded connection hole is provided on the side of the first clamping block 221, and a strip-shaped mounting hole extending along the third direction Z may be provided on the connecting section. This strip-shaped mounting hole engages with the threaded connection hole on the side of the first clamping block 221 via a fastener, thereby adjusting and locking the position of the connector clamp 22 in the third direction Z.

[0120] The strip-shaped mounting holes provide the joint clamp with 22-dimensional position adjustment capabilities, precisely matching the weld point position and adapting to different working angles and welding processes. The long-stroke design of the strip-shaped mounting holes provides a sufficient adjustment range to cover the adjustment range required for conventional construction. The positioning is reliable after the fasteners are tightened. The multiple adjustment structures work together to comprehensively improve the alignment accuracy of the joint clamp.

[0121] In some embodiments, the connector clamp 22 further includes an elastic element 226. Along the second direction Y, the elastic element 226 is compressed and abuts against the first clamping block 221 and the second clamping block 222. The elastic element 226 is sleeved on the first screw 2231. In this embodiment, the elastic element 226 is a pre-compressed elastic member, sleeved on the outside of the first screw 2231. It can provide elastic preload when locking the connector, avoid rigid impact damage to the connector, compensate for thread clearance, and improve the smoothness of movement of the second clamping block 222.

[0122] For example, the elastic element 226 can be a cylindrical compression spring, a wave spring, or an elastic rubber sleeve. Different types of elastic elements are suitable for different working conditions: cylindrical compression springs have stable elastic force and strong load-bearing capacity, and are suitable for conventional heavy-duty clamping scenarios; wave springs have small axial dimensions, which can reduce the overall thickness of the clamp, and are suitable for extremely confined cabinet areas; elastic rubber sleeves have both cushioning and anti-slip functions, and also have insulation properties, making them suitable for construction scenarios around live-line work, and offering flexible and diverse selection options.

[0123] In some embodiments, the connector clamp 22 further includes a guide member 227 extending along the second direction Y. The first clamping block 221 has a guide hole 228 extending along the second direction Y. One end of the guide member 227 extending in the second direction is connected to the second clamping block 222, and the guide member 227 passes through the guide hole 228 and slides in cooperation with the guide hole 228. In this embodiment, the guide member 227 is a rigid rod, sliding in cooperation with the guide hole 228 to restrict the rotation and sway of the second clamping block 222, ensuring that the second clamping block 222 only moves linearly along the second direction Y, thus ensuring smooth and stable movement.

[0124] For example, such as Figure 4 As shown, there are two guide members 227, which are located on both sides of the first locking member 223 along the first direction X.

[0125] Alternatively, in some embodiments not shown in the figures, a guide hole 228 extending along the second direction Y may be provided on the second clamping block 222. One end of the guide member 227 in the extending direction is connected to the first clamping block 221, and the guide member 227 passes through the guide hole 228 and slides in cooperation with the guide hole 228.

[0126] Alternatively, in some embodiments not shown in the figures, the second clamping block 222 may be fixedly mounted on the support assembly 21, while the first clamping block 221 may be movably mounted along the second direction Y. When the first screw 2231 rotates, it causes the first clamping block 221 to move closer to or further away from the second clamping block 222 along the second direction Y. The specific arrangement is similar to the embodiments described above and will not be repeated here.

[0127] In some embodiments, such as Figure 5 As shown, Figure 5The specific structure of the cable clamp 23 is shown. The cable clamp 23 includes a base 231, a sleeve 232, and a second locking member 233. The base 231 is mounted on the support assembly 21, specifically on the first support member 211. The sleeve 232 is connected to the base 231 and has an inner cavity extending through it along a first direction X, forming the aforementioned second clamping space 230. The sidewall of the sleeve 232 has a threaded hole 2321 extending radially along the sleeve 232 and communicating between the outside of the sleeve 232 and the inner cavity. The second locking member 233 includes a second screw 2331, which passes through and is screwed into the threaded hole 2321, with at least a portion of the second screw 2331 located within the second clamping space 230.

[0128] In this embodiment, the cable clamp 23 is mounted on the support assembly 21 via the base 231, providing a stable bearing foundation for the sleeve 232. The inner cavity of the sleeve 232 extends along the first direction X to form a second clamping space 230, which can completely enclose the cable body, correct its natural curvature, and ensure the cable axis is straight. The radial sleeve threaded hole 2321 on the side wall of the sleeve 232 cooperates with the second screw 2331. By screwing the second screw 2331, its end enters the second clamping space 230 and presses against the cable body, achieving radial locking of the cable. Simultaneously, the fixing method of the sleeve 232 and the second screw 2331 allows the cable clamp 23 to match various cable specifications, improving the versatility of the device.

[0129] Specifically, in some embodiments, the base 231 includes an arc-shaped support portion 2311, which has a strip-shaped hole 2312 extending along a first direction X and penetrating the convex and concave surfaces of the arc-shaped support portion 2311. The cable clamp 23 also includes a third screw 234 and a fastening nut 235, and a sleeve 232 is disposed on the concave surface of the arc-shaped support portion 2311. The third screw 234 passes through the strip-shaped hole 2312, and one end of the third screw 234 is connected to the sleeve 232, while the other end is threadedly connected to the fastening nut 235. When the fastening nut 235 is tightened, it is suitable for fixing the sleeve 232 to the concave surface.

[0130] In this embodiment, the concave surface of the arc-shaped support 2311 fits closely to the outer wall of the sleeve 232, providing stable support. Furthermore, the strip-shaped hole 2312 extends along the first direction X, allowing for fine-tuning of the sleeve 232's position along this direction. The third screw 234 cooperates with the fastening nut 235 to lock the sleeve 232 in place, ensuring convenient adjustment and reliable positioning. The arc-shaped support enhances the stability of the sleeve 232, and the fine-tuning structure allows for precise calibration of coaxiality, ensuring that the wire automatically aligns coaxially with the connector end face after insertion, resulting in a tight fit and consistent welding fusion quality.

[0131] For example, the base 231 is provided with bolt connection holes, and the base 231 is connected to the slide groove 2113 of the first connector 212 through the bolt connection holes and bolts.

[0132] For example, the second locking member 233 can be a hand-tightening bolt, such as a wing bolt.

[0133] Alternatively, exemplarily, the second locking member 233 can also be a clamping assembly with an elastic structure, such as including a push rod, a compression spring, and a locking nut. A radial through hole is provided in the sleeve 232 for the push rod to pass through. The push rod passes through the radial through hole of the sleeve 232, with its front end used to press against the wire body and its rear end fitted with the compression spring. The locking nut is screwed onto the push rod and located outside the sleeve 232. The compression spring is in a compressed state, abutting against the outer wall of the sleeve 232 and the locking nut. Tightening the locking nut compresses the spring and pushes the push rod to clamp the wire body.

[0134] Furthermore, due to the extremely small size of the solder joints on the copper core of a 2M coaxial cable, it is highly susceptible to incomplete soldering, meaning the solder only covers the surface and does not effectively contact the conductive copper core. If the solder is insufficient, the cable must be cut and remade; if the cable length is insufficient, rewiring is also necessary. Reworking each interface not only wastes resources but also incurs time costs and reduces operational efficiency.

[0135] Currently, judging the fullness of solder mainly relies on manual visual inspection by operators. Due to the limitations of the fineness of the solder joints, the accuracy of manual identification is low, making it difficult to accurately judge the quality of solder. At the same time, professional supervisors cannot check the work results in real time, which can easily lead to unqualified joints flowing into subsequent stages, further aggravating the resource waste and time cost caused by rework.

[0136] Based on this, in some embodiments, the cable connector fixing device 2 further includes an image acquisition unit 24, an image display, and a controller. The image acquisition unit 24 is mounted on the support assembly 21, specifically on the first support member 211. Along the second direction Y, the image acquisition unit 24 is located on one side of the connector clamp 22 and the cable clamp 23. The image acquisition unit 24 is used to acquire welding image information at the connection between the connector and the cable. The controller is electrically connected to the image acquisition unit 24 and the image display, and is configured to acquire the welding image information acquired by the image acquisition unit 24 and transmit it to the image display for display.

[0137] In this embodiment, the image acquisition unit 24, the image display, and the controller form a visual monitoring unit. Adding the image acquisition unit 24, the image display, and the controller allows for real-time acquisition and intuitive presentation of images of the welding area, effectively compensating for the insufficient accuracy of human visual perception and enabling clear observation of minute solder joint conditions. Monitoring personnel can simultaneously view the imaging screen, enabling real-time verification of the work process. This facilitates timely detection of defects such as cold solder joints and insufficient solder coverage, reducing the generation of defective products, avoiding rework wiring, and effectively saving material resources and work time.

[0138] For example, such as Figure 6 As shown, the image acquisition device 24 may include a camera mounting base 241 and a camera body 242, with the camera body 242 mounted within the camera mounting base 241. The camera mounting base 241 may be provided with bolt connection holes. Correspondingly, the first support member 211 is provided with two parallel and spaced-apart sliding grooves 2113 along the second direction Y. The camera mounting base 241 is mounted to the sliding grooves 2113 of the first support member 211 via the bolt connection holes and bolts. Understandably, the installation method of the camera mounting base 241 is similar to that of the aforementioned connector clamp 22 and cable clamp 23. Therefore, the installation position of the camera mounting base 241 along the first direction X is adjustable, which means the installation position of the image acquisition device 24 along the first direction X is also adjustable.

[0139] For example, the first support member 211 may also be provided with at least three sliding grooves 2113 arranged side by side and spaced apart along the second direction Y. Figure 3 Taking the illustrated embodiment as an example, the first support member 211 is provided with three sliding grooves 2113 arranged side by side and spaced apart along the second direction Y. Two of the sliding grooves 2113 are used to install the aforementioned connector clamp 22 and cable clamp 23, and the other sliding groove 2113 is used to install the image acquisition device 24. It can be understood that the number of sliding grooves 2113 on each first support member 211 can also be four, five, six, or other numbers.

[0140] In some embodiments, the cable connector fixing device 2 further includes a power supply 25, which is electrically connected to the image acquisition unit 24 and the image display, for providing power to both. For example, as... Figure 7 As shown, the power supply 25 includes a battery mounting base 251 and a battery, with the battery mounted inside the battery mounting base 251. The battery mounting base 251 is mounted to the groove 2113 of the first support member 211 via its own bolt connection holes and bolts.

[0141] For example, the controller, image acquisition unit 24, and image display can transmit image information wirelessly, such as through a wireless router; alternatively, they can transmit image information via signal cables, such as an HDMI cable. The image acquisition unit 24 is integrated with the support component 21, and its acquisition angle and distance can be determined based on the camera's focal length. By aiming a high-precision camera at the solder joint, the soldering image can be visualized in real-time and with high precision for viewing by operators and supervisors.

[0142] For example, the image acquisition device 24 is a high-definition camera with a camera resolution of 1080P, a transmission protocol of IEEE802.11n, a display delay of ≤200ms, an adjustable viewing angle within ±15°, and a distance of 5cm between the camera lens and the welding area.

[0143] For example, power supply 25 can provide operating power to image acquisition unit 24 by outputting 5 volts DC power via USB interface.

[0144] For example, the image display can be a TFT display screen, a mobile phone, a tablet, etc.

[0145] Furthermore, in some embodiments, the controller includes a processor and a memory. The processor is electrically connected to the image acquisition unit 24, the image display, and the memory, which stores preset welding image information. The processor is configured to acquire the welding image information acquired by the image acquisition unit 24 and transmit it to the image display for display. The processor is also configured to generate welding quality inspection information based on the welding image information acquired by the image acquisition unit 24 and the preset welding image information, and send the welding quality inspection information to the image display for display.

[0146] In this embodiment, the controller, with a processor at its core, integrates an image processing module and a storage module. The memory pre-stores standard weld point images and judgment parameters; the processor extracts image features in real time and compares them with preset information, automatically generating quality inspection results and displaying them. This system is highly efficient, accurate in identification, and responds quickly. This intelligent comparison function reduces reliance on manual experience, objectively quantifies weld point quality, quickly identifies welding defects, enables quality self-inspection and traceability, and improves the level of construction standardization and quality controllability.

[0147] The use of the fixing device 2 in this application specifically includes a fixing stage and a monitoring stage:

[0148] During the fixing stage: the support assembly 21 is fastened to the cabinet with bolts, the cable body is inserted into the sleeve 232 and the second locking member 233 is rotated to complete the locking. At the same time, the connector is placed in the connector clamp 22 and the first locking member 223 is turned to complete the locking.

[0149] During the monitoring phase: The image acquisition unit 24, pre-installed on the support component 21, automatically aligns with the welding point position. Power is supplied by the power supply 25, and the welding image information is transmitted to the image display. Operators and supervisors jointly carry out quality inspection work based on the split-screen display.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
