Description

Technical Field

[0001] The present invention relates to the technical field of connection terminals, in particular to a conductive connection terminal. Background Art

[0002] In the field of electrical connection, conductive connection terminals are key components for achieving circuit connection. Their performance and ease of use directly affect the reliability and maintenance efficiency of the electrical system. Traditional conductive connection terminals have many problems in the way the wires are fixed. Using bolts to fix the wires is a common method, but this method has obvious disadvantages in actual operation. Bolt fixing requires the use of tools to tighten and loosen, which is cumbersome to operate. It not only increases the time cost of installation and disassembly, but also in some occasions with limited space, the use of tools may be restricted, which brings great inconvenience to the operation. More importantly, the bolts may become loose after long-term use, affecting the stability of the connection, resulting in poor contact, increased resistance, and even circuit breakage, thereby affecting the normal operation of electrical equipment.

[0003] Although some existing direct connection terminals with quick fixing functions have solved the problem of installation efficiency to a certain extent, they have poor adaptability to wires of different sizes. Due to the various diameter specifications of the wires, when the diameter of the wires changes, it is difficult for the locking structure of these terminals to maintain a stable squeezing force on the wires. If the squeezing force is too large, the insulation layer of the wire may be damaged, and even the metal wire inside the wire may be deformed, affecting the conductive performance and service life of the wire; if the squeezing force is too small, the tight connection between the wire and the terminal cannot be guaranteed, and poor contact is likely to occur, which will also affect the stability of the electrical system. In addition, in some humid or dusty environments, moisture and dust can easily enter the inside of the terminal, causing safety hazards such as short circuits and leakage, while traditional conductive connection terminals often lack effective waterproof and dustproof measures. With the continuous development of electrical equipment and the increasing diversification of application scenarios, the requirements for conductive connection terminals are getting higher and higher. Not only do they need to have the functions of quick connection and disassembly, be able to adapt to wires of different sizes and ensure stable connection, but they also need to have good heat dissipation performance, waterproof and dustproof performance, etc. to ensure the safe and reliable operation of the electrical system.

[0004] Therefore, there is an urgent need to provide a conductive connecting terminal to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a conductive connection terminal to solve the problem that the existing direct connection terminals proposed in the above background technology usually use bolts to fix the wires, but the use of bolts results in the unchanged disassembly of the wires, and some existing direct connection terminals with quick fixing functions cannot cope with wires of various sizes, resulting in that when the diameter of the wire changes, the squeezing force of the locking structure on the wire will also change, resulting in the problem that the fixation of the wire is not stable enough.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a conductive connection terminal, comprising a terminal housing, and insertion openings inserted on both sides of the terminal housing;

[0012] Preferably, a circular hole and a side groove are provided just above the upper clamping plate, the circular hole is opened at the top of the terminal housing, and the side grooves are symmetrically distributed on both sides of the circular hole and are connected to the circular hole.

[0013] Preferably, the circular hole is movably connected to the cylinder, and the side groove is slidably connected to the rack.

The water retaining ring of appropriate specifications can be selected according to the diameter of the wire body, which greatly improves the safety of the terminal in humid environments. Although the dustproof design is not explicitly mentioned, the overall structure can also reduce dust intrusion to a certain extent, provide a clean environment for the internal conductive parts, and ensure stable and reliable electrical connections.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-5 , the present invention provides a technical solution: a conductive connection terminal, comprising a terminal housing 1, and an insertion port 101 inserted on both sides of the terminal housing 1;

[0031] An insulating cylinder 102 is fixedly installed at the center of the terminal housing 1, a conductive plate 103 is fixedly connected to the middle of the insulating cylinder 102, and a wire body 104 is connected through the insertion port 101;

[0033] Wherein, a waterproof component 3 is arranged between the insulating tube 102 and the quick clamping component 2 .

[0034] A circular hole 203 and a side groove 204 are provided directly above the upper clamping plate 215 . The circular hole 203 is opened at the top of the terminal housing 1 , and the side grooves 204 are symmetrically distributed on both sides of the circular hole 203 and communicated with the circular hole 203 .

[0035] The circular hole 203 is movably connected to the cylinder 205 , and the side groove 204 is slidably connected to the rack 207 ; the side groove 204 allows the rack 207 to only be raised and lowered, while the cylinder 205 can be raised and lowered and rotated in the circular hole 203 .

[0036] The movable frame 210 is fitted to the top of the terminal housing 1 , and a locking block 211 is fixedly connected to the inner side of the movable frame 210 , and the locking block 211 is locked and connected to the rack 207 .

[0037] A protrusion 213 is fixedly connected to the top of the terminal housing 1, and a return spring rod 214 is fixedly connected to the side of the protrusion 213. The other end of the return spring rod 214 is fixedly connected to the movable frame 210, and a shift plate 212 is fixedly connected to the top of the movable frame 210; the return spring rod 214 can push the movable frame 210 to reset, so that the locking block 211 and the rack 207 are always engaged when there is no external force. When the wire body 104 needs to be disassembled, the movable frame 210 only needs to be shifted to complete the quick disassembly of the wire body 104.

[0038] The waterproof component 3 includes a stepped groove 301 opened at the top and bottom of the terminal housing 1, and a connecting column 304 is connected to the middle of the stepped groove 301.

[0040] A pressure sensor is provided at the connection between the cylinder 205 and the upper clamping plate 215, and the pressure sensor is electrically connected to an external display device. The pressure sensor is used to monitor the clamping pressure of the upper clamping plate 215 on the wire body 104 in real time, and transmit the pressure data to the display device. At the same time, the rotating cylinder 205 is made to continue to descend under the action of the threaded sleeve 206 that cannot rotate, thereby enabling the upper clamping plate 215 to further clamp the wire body 104. The pressure data monitored in real time by the pressure sensor can help the operator to promptly detect abnormal pressure conditions, such as excessive or insufficient pressure, so as to make timely adjustments to ensure the normal operation of the conductive connection terminal.

[0041] Heat dissipation fins are evenly distributed on the outer surface of the terminal housing 1, and the heat dissipation fins are made of metal materials with high thermal conductivity, such as aluminum alloy. The heat dissipation fins are connected to the inside of the terminal housing 1 through thermal conductive silicone to improve the heat conduction efficiency. A heat dissipation groove is opened on the surface of the insulating tube 102, and the heat dissipation groove is filled with heat dissipation silicone to enhance the heat dissipation capacity of the insulating tube 102. When the conductive connection terminal is in operation, heat is generated when current passes through the conductive plate 103 and the wire body 104. The heat dissipation fins and the heat dissipation groove can dissipate the heat in time, reduce the temperature inside the terminal, prevent problems such as aging of the wire body and decreased conductivity due to excessive temperature, and improve the working stability and service life of the conductive connection terminal.

[0042] Working principle: Before using this conductive connection terminal, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, first, the paddle 212 is toggled to move the movable frame 210, so that the positioning block 211 moves and disengages from the rack 207, and then the cylinder 205 can be freely raised and lowered, and finally the line body 104 can be quickly changed from locked to movable, avoiding the problem of difficult disassembly caused by direct extrusion of traditional bolts or other extrusion methods;

[0043] When fixing the wire body 104, the wire end of the wire body 104 is inserted into the insulating cylinder 102 and connected to the conductive plate 103. Then, when the engagement between the positioning block 211 and the rack 207 is cancelled, the cylinder 205 is first pressed to make the upper clamping plate 215 move down and close to the wire body 104. Then, the paddle 212 is released to restore the engagement between the positioning block 211 and the rack 207. At this time, the upper clamping plate 215 and the lower arc support plate 202 clamp the wire body 104 together. Then, the cylinder 205 is rotated continuously to make it continue to descend under the action of the non-rotatable threaded sleeve 206, thereby prompting the upper clamping plate 215 to further clamp the wire body 104. Finally, the wire body 104 can be stably fixed while ensuring that the wire body 104 can be quickly disassembled.

[0044] The magnetic strip 302 is sucked out of the stepped groove 301 by a magnetic suction tool, so that the connecting column 304 can drive the water retaining ring 305 to move upward and be pulled out of the stepped groove 301, thereby replacing the water retaining ring 305 installed with water-blocking rubber 306 of different diameters, so that the water-blocking rubber 306 can prevent external liquid from penetrating into the insulating tube 102 and affecting safety.
