For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0037] Example 1

[0038] A cable head production competition device is designed to simulate the cable head production process in the actual cable construction process. It has the characteristics of reasonable structure, clear functions and convenient assembly. It is suitable for various cable head production skill competitions or training teaching scenarios. Figure 1 FIG. 1 shows a schematic diagram of the overall structure of an embodiment of the present invention, as shown in FIG. Figure 1 As shown, it includes: a main bracket, which includes a support frame 1, a cross bar 2, a clamp assembly 3 and an insulator assembly 4; the support frame 1 is a three-dimensional structure, and can be formed by welding or bolting rectangular steel pipes or aluminum profiles, and has good stability and load-bearing capacity.

[0039] The two ends of the crossbar 2 are connected to the left and right opposite sides of the support frame 1; the crossbar 2 includes a clamp crossbar 210 and an insulator crossbar 220; the crossbar 2 is a platform for installing other functional components, which is laterally connected between the left and right opposite sides of the support frame 1, and includes a clamp crossbar 210 and an insulator crossbar 220 arranged in two layers.

[0040] The clamp crossbar 210 is positioned below the insulator crossbar 220, and the clamp assembly 3 is mounted on the clamp crossbar 210. The clamp assembly 3 is used to secure the cable. The clamp crossbar 210 is installed below the crossbar 2 and is used to mount the clamp assembly 3. The clamp assembly 3 can be a U-shaped clamp or an adjustable fastener structure, which can firmly clamp the cable used by the contestant, ensuring that the cable does not slip or rotate during the production process, improving operational safety and accuracy.

[0041] The insulator assembly 4 is arranged on the insulator crossbar 220. The insulator assembly 4 is used to support the cable head and insulate the cable head from other components. The insulator crossbar 220 is located above the clamp crossbar 210 and is installed with the insulator assembly 4. The insulator assembly 4 can be made of porcelain or composite material insulators. The top of the insulator assembly is provided with a cable head positioning groove or mounting socket for positioning and fixing the cable head. At the same time, it plays an effective electrical insulation role to prevent voltage interference or short circuit risks during the cable head production process. The installation method of the insulator assembly supports quick disassembly and replacement, which facilitates the production training of different types of cable heads.

[0042] Furthermore, in this embodiment, the support frame 1 includes a rectangular frame 110 and a triangular support frame 120. The rectangular frame 110 is vertically arranged at the center of the triangular support frame 120, and the rectangular frame 110 is maintained perpendicular to the target plane by the triangular support frame 120. In order to improve the stability and portability of the overall structure, the support frame 1 in this embodiment includes a rectangular frame 110 and a triangular support frame 120. The rectangular frame 110 is the main load-bearing component, and has an overall longitudinal rectangular structure. It is composed of metal profiles, such as aluminum profiles or steel, welded or bolted together, and is used to support the crossbar assembly and the various functional components installed thereon. The rectangular frame 110 is vertically arranged at the center of the triangular support frame 120, and the triangular support frame 120 is arranged at the bottom of the support frame 1 to contact the ground or platform and provide a stable support foundation. The triangular support frame 120 preferably adopts an equilateral or unequal triangle structure, with its two sides fixedly connected to the rectangular frame 110 and the bottom side parallel to the target plane where the device is placed. This structural design fully utilizes the stability advantage of the triangular structure in terms of force, so that the entire support frame is not prone to tilting or shaking during the cable head production operation, thereby ensuring the safety of the contestants or operators. At the same time, the rectangular frame 110 is fastened to the triangular support frame 120 through connectors such as bolts, pins or welded parts, so as to achieve modular assembly of each component without sacrificing the strength of the device, which is convenient for transportation and disassembly. The structure ensures that the rectangular frame 110 can reliably remain perpendicular to the target plane, that is, the ground or work surface, and provide a stable and reliable basic support for the installation of the crossbar and the clamp assembly and insulator assembly thereon, effectively improving the force uniformity of the entire structure and the stability of the operation process. This design is not only conducive to the rapid deployment of equipment under various site conditions, but also facilitates subsequent maintenance and upgrades, meeting the diverse needs of cable head production skill competitions and teaching and training.

[0043] Furthermore, in this embodiment, a functional position is provided at the top of the support frame 1, and the functional position is used to install lighting equipment, fans, and cameras. A protective grounding assembly is provided at the bottom of the support frame 1. The functional position refers to a reserved structural installation interface or fixed installation surface, which is provided in the form of a screw hole group, a guide rail groove, or a multi-functional bracket, distributed at the top edge or middle of the support frame 1, and is used to install auxiliary devices such as lighting equipment, fans, and cameras. The lighting equipment can be an LED anti-glare lamp or a strip work light. After being installed in the functional position, it provides the operator with stable and uniform lighting conditions in different lighting environments, ensuring the visibility and accuracy of the production operation. The fan device can provide local ventilation and cooling for the operator, which is particularly suitable for high-temperature or enclosed training environments, improving operator comfort and preventing misoperation due to environmental discomfort. The camera device can be used to record the entire competition process or training operation process, supporting functions such as remote monitoring, score playback, teaching explanations, and behavioral norms assessment. All of the above equipment can be modularly and quickly installed or disassembled through the functional position, with good scalability and practicality.

[0044] Furthermore, in order to ensure the safety of electricity use and meet the grounding requirements of electrical equipment, a protective grounding assembly is also provided at the bottom of the support frame 1. The protective grounding assembly includes a grounding terminal, a grounding wire and a grounding connector, one end of which is firmly connected to the metal component at the bottom of the support frame 1 by bolts or welding, and the other end is led to the ground and connected to the grounding electrode or the public grounding system. The protective grounding assembly can effectively prevent the risk of electric shock caused by static electricity accumulation, electrical failure or lightning induction, improve the overall electrical safety level of the equipment, and ensure the personal safety of the operator and the stability of the device operation. By setting the functional position at the top and configuring the protective grounding assembly at the bottom, the convenience of the operating environment and the safety of the system are taken into account, meeting the comprehensive requirements of modern competitions and teaching practices for the versatility, intelligence and safety standards of equipment.

[0045] Furthermore, in this embodiment, measuring tools are provided on opposite sides of the support frame 1, movably connected to the support frame 1. These measuring tools are used to determine the accuracy of the contestant's cable head fabrication. The measuring tools are preferably mounted on the side columns of the support frame 1 and are removably or adjustably connected to the support frame 1 via a movable connection structure. The movable connection structure may include a slide rail, a rotating hinge, a telescopic arm, a magnetic assembly, or a slot-type plug-in device, allowing the measuring tools to be adjusted and rotated according to measurement requirements to accommodate measurement operations of different specifications and fabrication postures. The measuring tools may be composed of components such as a high-precision ruler, a laser rangefinder, a spirit level, an angle gauge, a limit stop, and a photoelectric sensor. These measuring tools are placed on both sides of the support frame and can be used to compare the completed cable head components with the contestant's. The core function of the measuring tools is to accurately determine whether the contestant's cable head meets technical specifications or competition standards in terms of key parameters such as spatial position, length reserve, number of wrapping layers, stripping depth, and angular deviation. For example, a scaled limit ruler can be used to measure whether the exposed length of the cable core is within the specified tolerance range, or a laser indicator line can be used to determine whether the axis of the cable head is aligned with the installation direction.

[0046] Furthermore, in this embodiment, there are two insulator rungs 220, with the spacing between them being greater than or equal to 3 / 10 of the height of the rectangular frame 110. There are two clamp rungs 210, with the spacing between them being greater than or equal to 1 / 20 of the height of the rectangular frame 110. The ratio of the height of the triangular support frame 120 to the height of the rectangular frame 110 is 1:8 to 2:5. Two insulator rungs 220 are arranged in parallel, one above the other, to accommodate insulator assemblies and support cable heads of different types or levels. The vertical spacing between the two insulator rungs 220 is greater than or equal to 3 / 10 of the total height of the rectangular frame 110. This ratio ensures ample vertical space for the insulator assemblies, preventing congestion, crossover, or difficulty in securing cable heads due to narrow spacing. This height setting also facilitates the adjustment of the cable head's posture during construction or demonstration, aligning it more closely with real-world conditions and enhancing the effectiveness of training or competitions. The clamp crossbars 210 are also provided in two, and are distributed vertically between the two clamp crossbars 210, with a spacing greater than or equal to 1 / 20 of the height of the rectangular frame 110, which can effectively prevent the cable from bending, squeezing, etc. when being fixed, while reserving installation operation space for the clamp assembly, facilitating tool intervention and construction evaluation. The ratio between the height of the triangular support frame 120 and the height of the rectangular frame 110 is set to a certain range, i.e., 1:8 to 2:5. When the ratio is close to 1:8, the center of gravity of the device is lower, which is suitable for indoor venues or small demonstrations; when the ratio is close to 2:5, the triangular support frame is higher, which can improve the overall rigidity and is suitable for deployment in outdoor environments or complex ground conditions.

[0047] The present invention organically combines the support frame, crossbar, clamp assembly and insulator assembly through the main bracket, thereby achieving stable support and effective isolation of the cable and the cable head during competition or training. The clamp assembly is arranged on the lower crossbar, which can firmly fix the cable to prevent it from sliding or shaking, thereby improving operational stability and manufacturing accuracy. The insulator assembly is arranged on the upper crossbar to support the cable head and insulate it from other metal parts, effectively avoiding short circuits or electrical interference, and ensuring electrical safety during use. The structural layering is clear and the functional divisions are clear, which is conducive to the contestants to quickly understand and standardize operations, thereby improving training efficiency and competition fairness. The device has strong adaptability and can be used to fix cables of various specifications. It has good practicality and promotion value.

[0048] Example 2

[0049] A cable head production competition system comprises: the cable head production competition device as described above and a trolley, wherein the trolley is used to place competition tools. The cable head production competition device serves as an operating platform, and the trolley serves as an auxiliary tool carrying platform, together forming a complete competition system integrating operation, evaluation, and tool management. The trolley is a mobile multifunctional tool platform, preferably set to a four-wheel structure, and the wheels are equipped with a brake locking mechanism to achieve stable positioning and flexible movement functions. The main body of the trolley is made of lightweight metal material (such as aluminum alloy, stainless steel), and has good load-bearing performance and durability. The trolley is provided with multiple functional areas, including: tool tray area, material storage area, waste material delivery area, etc. In actual application, the trolley can be pushed to the vicinity of the player's operating area to provide players with instant access to tools and materials during the cable head production process, reduce the impact of players' frequent movement to obtain tools on the rhythm of the game, and improve the fluency and efficiency of the game.

[0052] Fix the competition cable on the clamping hoop assembly 3; the contestant or operator first arranges the competition cable on the main bracket of the device and places the cable in the clamping position of the clamping hoop assembly 3.

[0053] Connect the completed cable head to the insulator assembly 4. After the cable is securely fixed, participants will use wire cutters, wire strippers, insulation treatment tools, and other tools to perform layered stripping of the cable's outer jacket, shielding layer, and conductor, perform end treatment, wrapping, and accessory installation, according to the competition's technical specifications or teaching requirements, completing the standard cable head. Once completed, connect the end of the cable head to the insulator assembly 4 located on the insulator crosspiece 220.

[0054] Remove the measuring tools on the left and right opposite sides, read the actual production size of the completed cable head, and compare it with the standard cable head size. According to the competition process, the referee or evaluator will remove the measuring tools installed on the left and right opposite sides of the device through movable connections. The measuring tools include rulers, limit devices, angle measuring tools, laser aligners, etc., which can be moved freely to adapt to different measurement needs. The referee uses the measuring tools to measure and read the key parameters of the cable head, such as: exposed conductor length, stripping layer size, wrapping position, installation angle, symmetry and straightness, etc. The actual measurement results are then compared with the standard scoring specifications, and quantitative scores are given based on the deviation range and production quality to assess the contestants' operating level.

[0055] This embodiment covers the complete cable head process, from fixing and manufacturing to measurement and evaluation, while also balancing operational safety, structural adaptability, and objective evaluation. By combining standardized operating procedures with a precise measurement mechanism, it effectively improves the fairness and operability of skill competitions.
