[0011] Preferably, the collapse-preventing end column is provided with a round head at one end, which reduces the friction area with the spring and improves the service life of the equipment.
[0012] Beneficial effects:
[0013] 1. In the prior art, contactless contactors with protective functions usually require the wires to be inserted into wire holes during installation and fixed by winding or other methods. The factory environment is usually full of various uncertainties, such as mechanical vibration, electromagnetic interference, temperature changes, etc. These factors threaten the stable operation of the contactless contactor. Once affected by vibration, the connection between the contactless contactor and the wire will loosen or even fall off. This unexpected falling off will not only cause production interruption and affect production efficiency, but also cause more serious production accidents, such as equipment damage, fire and explosion. Some contactors are equipped with fixing devices to improve the stability of the connection with the wires. However, these fixing devices often use increased pressure to achieve fixation. Although this approach enhances the stability of the connection to a certain extent, it also brings new problems. Excessive pressure can easily cause the surface of the wire to wear or bend, thereby affecting the electrical performance and service life of the wire. The existing fixing device The design of the contactors is often lacking in flexibility and cannot be easily adjusted according to the diameter of the wires. This means that when faced with wires of different diameters, the scope of application of the contactors will be significantly limited. Users have to prepare contactors of various specifications for wires of different diameters. This not only increases the cost of the equipment, but also brings great inconvenience to installation and maintenance. To address this problem, the utility model solves it by installing a fixed column. After the staff inserts the wire into the wire entry hole, a screwdriver or other tool is inserted into the plug-in slot at the top of the movable rod, and the vertical end bevel gear of the movable rod is driven to rotate and engage the parallel end bevel gear, so that the limiting ring drives the inner column to rotate and the threaded column of the threaded connection moves toward one end of the limiting ring, so that the side arc clamping grooves of the movable column and the fixed column clamp the wire to prevent the wire from falling off. At the same time, since the distance between the movable column and the fixed column is adjustable, it can adapt to different types of wires and equipment, thereby improving the scope of application and achieving the effect of improving the scope of application of the equipment.
[0014] 2、In the prior art, the moving column usually moves in the inner wall of the side column hole, and during this movement, the moving column is always subjected to the action of friction. This design is to ensure that the moving column can maintain a stable position and direction when rotating or moving. However, in actual operation, when rotating the moving rod, due to the uneven distribution of friction, the moving column is prone to skew in the inner wall of the side column hole. This skew is not a trivial matter, as it directly leads to the phenomenon of thread slipping, i.e., the precise fit between threads is destroyed, making the threads unable to effectively engage, thereby reducing the stability and reliability of mechanical connections. Thread slipping not only increases equipment wear and tear but also leads to more serious consequences, such as equipment damage. Because once the threads are damaged, repair is usually difficult, requiring replacement of the entire component, which not only increases maintenance costs but also prolongs equipment downtime. More seriously, this skew and thread slipping condition can accelerate the overall wear and tear of the equipment, reducing its service life. Because every time the moving column is skewed in the inner wall of the side column hole, it causes additional pressure and wear on the inner wall, and this wear is cumulative, with the degree of wear becoming more and more serious over time, ultimately affecting the normal operation of the equipment. To address these problems, the utility model adopts the installation of an equalizing spring to achieve the addition of an equalizing spring in the system. When the friction increases in a certain area, the spring can accumulate elastic potential energy to absorb and alleviate this sudden change in force, and then release this energy at the appropriate time to act on the moving column in a smooth and balanced manner, thereby better balancing the additional resistance caused by uneven friction. This buffering and balancing effect significantly improves the stability and smoothness of equipment operation, reducing the occurrence of "thread slipping" and "thread misalignment". More importantly, the use of the equalizing spring not only prevents thread damage but also significantly reduces wear caused by uneven friction. The threads remain in good condition, ensuring stable connections, thereby directly improving the overall reliability and service life of the equipment. In addition, due to the reduction in unexpected downtime and maintenance frequency, the maintenance cost of the equipment is also reduced, providing users with higher economic benefits and better user experience, achieving the effect of improving the service life of the equipment.
[0015] 3、In the prior art, when the equalizing spring is compressed, the internal structure thereof will change, and the change is controllable under normal circumstances, but in some extreme cases, if the compression force is too large or the compression manner is improper, the equalizing spring will collapse to the center thereof, and the collapse is not a simple deformation, but a destructive change of the internal structure, which will directly affect the elastic deformation capacity of the equalizing spring, and once the elastic deformation capacity of the equalizing spring is affected, it means that the equalizing spring cannot work normally in the designed manner, and the force originally uniformly distributed will be concentrated on a point or a region, thereby causing local excessive pressure, and the unbalanced force distribution not only reduces the efficiency of the equalizing spring, but also leads to a more serious consequence, i.e., the destruction of the overall structure of the spring, and once the structure of the equalizing spring is destroyed, the function thereof will be seriously affected, and the force originally used to balance and stabilize the system becomes unpredictable or even completely invalid, and in view of the problems, the utility model adopts the mode of installing the anti-collapse end column to solve the problems, so that when the equalizing spring is compressed, the anti-collapse end column prevents the equalizing spring from being compressed to the center thereof, the length of the anti-collapse end column is more than half of the natural length of the equalizing spring, the center of the half length of the equalizing spring is most fragile when the equalizing spring is compressed, and is easy to collapse to the center, and the anti-collapse end column prevents the collapse, thereby ensuring normal use of the equipment and improving the service life of the equipment.

The surface linear array of the side arc clamping groove 205 is provided with an anti-skid groove 2013, which prevents the vertical movement of the wire by parallel anti-skid grooves 2013, preventing it from falling off. The inner wall of the side limiting groove 2010 is provided with an end circular groove 2011 at both ends, which reduces the collision of the assembly in the groove with the two ends of the end circular groove 2011, thereby reducing wear and improving the service life of the equipment. The top of the contact device 1 is fixed with a side high block 102 on both sides, which can provide a better holding surface, facilitating installation and maintenance, and at the same time, if additional accessories such as heat sinks or fixing supports need to be installed, this design also provides convenience, improving user experience.
[0028] The other end of the moving column 201 is fixed with an equalizing spring 4, and the moving column 201 usually moves in the inner wall of the side column hole 2. During this movement, the moving column 201 is always subject to friction. This design is to ensure that the moving column 201 can maintain a stable position and direction when rotating or moving. However, in actual operation, when rotating the moving rod 208, due to the uneven distribution of friction, the moving column 201 in the inner wall of the side column hole 2 is prone to skew. This skew is not a trivial matter, as it directly leads to the phenomenon of thread slipping, which means that the precise fit between threads is destroyed, making the threads unable to effectively engage, thereby reducing the stability and reliability of mechanical connection. Thread slipping not only increases the wear and tear of equipment, but also leads to more serious consequences, such as equipment damage. Because once the threads are damaged, repair is usually difficult, and the entire component needs to be replaced, which not only increases maintenance costs, but also prolongs the downtime of the equipment. More seriously, this skew and thread slipping can accelerate the overall wear and tear of the equipment, reducing its service life. Because every time the moving column 201 skews in the inner wall of the side column hole 2, it causes additional pressure and wear on the inner wall, and this wear is cumulative, the degree of wear will become more and more serious over time, eventually affecting the normal operation of the equipment. The installation of the equalizing spring 4 solves this problem, which achieves the effect of adding an equalizing spring 4 to the system when the friction increases in a certain area. The spring can accumulate elastic potential energy to absorb and alleviate this sudden force change, and then release this energy at the appropriate time to act on the moving column 201 in a smooth and balanced manner, thereby better balancing the additional resistance caused by uneven friction. This buffering and balancing effect significantly improves the stability and smoothness of equipment operation, reducing the occurrence of "thread slipping" and "thread misalignment". More importantly, the use of the equalizing spring 4 not only prevents thread damage, but also significantly reduces wear and tear caused by uneven friction. The threads remain in good condition, ensuring stable connection, thereby directly improving the overall reliability and service life of the equipment. In addition, due to the reduction of unexpected downtime and maintenance frequency, the maintenance cost of the equipment is also reduced, bringing higher economic benefits and better user experience to users, achieving the effect of improving the service life of the equipment.The other end of the movable column 201 is fixed with a collapse-preventing end column 401. When the equalizing spring 4 is compressed, the internal structure thereof will change, which change is controllable under normal circumstances, but in some extreme cases, if the compression force is too large or the compression mode is improper, the equalizing spring 4 will collapse inwardly, which is not a simple deformation, but a destructive change of the internal structure, which will directly affect the elastic deformation capacity of the equalizing spring 4. Once the elastic deformation of the equalizing spring 4 is affected, it means that it can no longer work normally in the designed mode, and the originally uniformly distributed force will now be concentrated in a certain point or area, causing excessive local pressure. This uneven force distribution not only reduces the efficiency of the equalizing spring 4, but also leads to a more serious consequence - the destruction of the overall structure of the spring. Once the structure of the equalizing spring 4 is destroyed, its function will be severely affected, and the originally balanced and stable force of the system becomes unpredictable, or even completely fails. The installation of the collapse-preventing end column 401 solves this problem, and when the equalizing spring 4 is compressed, the collapse-preventing end column 401 prevents the equalizing spring 4 from being compressed inwardly. The length of the collapse-preventing end column 401 exceeds half of the natural length of the equalizing spring 4. When the equalizing spring 4 is compressed, the center of the half length is the most fragile and prone to collapse inwardly. The collapse-preventing end column 401 prevents this, thereby ensuring normal use of the equipment and improving the service life of the equipment. The one end of the collapse-preventing end column 401 is provided with a round head, which reduces the friction area with the spring and improves the service life of the equipment.
[0029] The working principle of the utility model is: when the staff inserts the wire into the wire hole 101, the screwdriver or other tools are inserted into the plug-in slot 209 at the top of the movable rod 208, and the vertical end bevel gear 207 of the movable rod 208 is rotated to mesh with the parallel end bevel gear 206, so that the limiting ring 3 drives the inner column to rotate, the threaded column 202 connected by screwing moves to the end close to the limiting ring 3, and the side arc clamping groove 205 of the movable column 201 and the fixed column 203 clamps the wire to prevent the wire from falling off.
