Description

Technical Field

[0001] This utility model relates to the field of materials science and technology, and in particular to anti-detachment terminal connectors. Background Technology

[0002] Terminals are key components used to achieve electrical connections. They are made of conductive materials (such as copper and iron) and come in various shapes (such as needle-shaped, plate-shaped, and column-shaped). They can be connected to wires or electrical equipment through crimping, soldering, and plugging to transmit current or signals. Their design combines mechanical structures (such as snap-fit ​​and threaded connections) with material properties (conductive and insulating materials) to ensure the reliability of electrical connections and to withstand complex environments of vibration and high temperature in industrial automation, automotive, and aerospace fields. They are the basic components for achieving stable connections in circuit systems.

[0003] Existing terminal connectors use threaded connections to connect terminals. However, after prolonged use, rust can form on the thread surface, making disassembly difficult and even affecting conductivity due to poor contact (e.g., increased resistance and overheating caused by rust on power terminals). Current technology embeds permanent magnets in the snap-fit ​​structure to achieve pre-positioning using magnetic force. This not only ensures a stable connection but also reduces the accuracy requirements for manual alignment. The snap-fit ​​can be locked with a single hand. However, the magnetic field generated by the permanent magnet attracts iron filings and metal dust from the air. When these accumulate in the gaps between the connector terminals, they form "metal bridges," leading to short circuits. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-detachment terminal connector, which aims to improve the problem in the prior art where the magnetic field generated by the embedded permanent magnet attracts iron filings and metal dust in the air when the terminal is fixed, and after accumulating in the gap of the connector terminal for a long time, it will form a "metal bridge" and thus cause a short circuit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-detachment terminal connector, comprising a mounting plate, wherein multiple clamping mechanisms are equidistantly fixedly connected to the front side of the outer wall of the mounting plate, the multiple clamping mechanisms being used to clamp and fix the terminals; fixing mechanisms are installed at the four corners of the mounting plate, the fixing mechanisms being used to fix the terminal connector in the required position; each of the multiple clamping mechanisms includes a clamping frame, wherein the upper and lower ends of the middle part of the clamping frame are slidably connected to buckles, and multiple steel wires are equidistantly fixedly connected to the top left and right ends of the outer wall of the buckles; and multiple power components are installed on the outer wall of the clamping frame.

[0006] As a further description of the above technical solution:

[0007] Each of the multiple power components includes a pressing plate, which is installed on the outer wall of the clamping frame. A rotating frame is fixedly connected to the left and right ends of the adjacent sides of the outer walls of the multiple pressing plates. A rotating shaft is rotatably connected inside the bottom end of the rotating frame. The outer wall of the rotating frame is fixedly connected to the other end of the outer wall of the steel wire. A spring is fixedly connected to the outer wall of the buckle on the side away from each other.

[0008] As a further description of the above technical solution:

[0009] Each of the aforementioned fixing mechanisms includes a retaining ring, which is installed at the four corners of the mounting plate. A base is installed at the outer rear end of the retaining ring. A drive shaft is rotatably connected to the front end of the outer wall of the base. A triangular knob is fixedly connected to the front end of the outer wall of the drive shaft. A bevel gear one is fixedly connected to the rear end of the outer wall of the drive shaft. Bevel gear two is installed on both the left and right sides of the outer wall of bevel gear one. The outer walls of bevel gear one and bevel gear two are meshed. A threaded rod is fixedly connected to the outer wall of each of the multiple bevel gear two on the side furthest from each other. A threaded bracket is installed on the outer wall of the threaded rod. The rear end of the threaded bracket is threadedly connected to the outer wall of the threaded rod.

[0010] As a further description of the above technical solution:

[0011] The clamping frame has brackets installed at both the upper and lower ends of its outer wall. The inner wall of one of the brackets is slidably connected to the outer wall of the rotating frame. The inner wall of the bracket is fixedly connected to the outer wall of the rotating shaft. The other end of the outer wall of the spring is fixedly connected to the inner wall of the bracket.

[0012] As a further description of the above technical solution:

[0013] A limiting plate is installed at the top of the outer wall of the buckle. The outer wall of the limiting plate is fixedly connected to the inner wall of the bracket, and the outer wall of the buckle is slidably connected to the inside of the limiting plate.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the retaining ring has grooves on both the left and right ends, and the inside of the grooves is slidably connected to the outer wall of the threaded frame.

[0016] As a further description of the above technical solution:

[0017] Limiting grooves are provided on the left and right sides of the front end of the outer wall of the base, and the interior of the limiting grooves is slidably connected to the rear end of the outer wall of the threaded frame.

[0018] As a further description of the above technical solution:

[0019] Multiple conductive blocks are fixedly connected at equal intervals in the middle of the mounting plate, and the conductive blocks are installed inside the clamping frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the pressing plate is pressed to move the buckle to the outside of the clamping frame, the terminal can be inserted. At this time, the spring is compressed and contracts to accumulate elastic potential energy. After the terminal is positioned, the pressing plate is released, and the spring moves the buckle to the inside of the clamping frame to fix the terminal through elasticity. The terminal can be separated by pressing the pressing plate again. This structure solves the problem that when the permanent magnet is embedded to fix the terminal, its magnetic field attracts iron filings and metal dust to accumulate and form a "metal bridge" that causes a short circuit.

[0022] 2. In this utility model, when the bevel gear two drives the threaded rod to rotate, the threaded frame moves in the limiting groove along the axial diameter of the threaded rod. Rotating the triangular knob causes the outer side of the threaded frame to move into the retaining groove of the retaining ring, thereby fixing the base and the retaining ring. This solves the problems of wear on the terminal hole threads caused by repeated screw disassembly, stripping of the screw holes in the socket housing, especially the difficulty in repairing damaged screw holes in plastic sockets requiring overall replacement, and the inability to remove the terminal connector due to rusted screws and forced disassembly.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 , Figure 5 and Figure 6 This utility model provides an embodiment of an anti-detachment terminal connector, including a mounting plate 1. Multiple clamping mechanisms 2 are equidistantly fixed to the front side of the outer wall of the mounting plate 1, used to clamp and fix the terminals. Fixing mechanisms 3 are installed at each of the four corners of the mounting plate 1, used to fix the terminal connector in the desired position. Each clamping mechanism 2 includes a clamping frame 201. A buckle 202 is slidably connected to the upper and lower ends of the middle part of the clamping frame 201. Multiple steel wires 203 are equidistantly fixed to the left and right ends of the top of the outer wall of the buckle 202. Multiple power components 204 are installed on the outer wall of the clamping frame 201. Each power component 204 includes a pressing plate 2041, installed on the outer wall of the clamping frame 201. The outer walls of the multiple pressing plates 2041 are connected to each other on adjacent sides. A rotating frame 2042 is fixedly connected to each end of the clamp 201. A rotating shaft 2043 is rotatably connected to the bottom end of the rotating frame 2042. The outer wall of the rotating frame 2042 is fixedly connected to the other end of the outer wall of the steel wire 203. A spring 2046 is fixedly connected to the outer wall of the buckle 202 on the opposite side. A bracket 2045 is installed on the upper and lower ends of the outer wall of the clamp 201. The inner wall of the opposite end of the bracket 2045 is slidably connected to the outer wall of the rotating frame 2042. The inner wall of the bracket 2045 is fixedly connected to the outer wall of the rotating shaft 2043. The other end of the outer wall of the spring 2046 is fixedly connected to the inner wall of the bracket 2045. A limit plate 2044 is installed on the top of the outer wall of the buckle 202. The outer wall of the limit plate 2044 is fixedly connected to the inner wall of the bracket 2045. The outer wall of the buckle 202 is slidably connected to the inside of the limit plate 2044.

[0034] Specifically, brackets 2045 are installed at the upper and lower ends of the clamping frame 201. Multiple rotating frames 2042 that can slide on the top of the brackets 2045 are provided. The bottom of the pressing plate 2041 is welded to the rotating frames 2042. A rotating shaft 2043 installed at the bottom of the rotating frame 2042 can rotate flexibly inside. Due to the limiting effect of the rotating shaft 2043, when the pressing plate 2041 is pressed, the other end of the rotating frame 2042 moves upward synchronously using the lever principle. The connection and traction of the steel wire 203 causes the buckle 202 to move upward. A limiting plate 2044 is installed on the outer wall of the buckle 202. The interior of the limiting plate 2044 provides a channel for the sliding of the buckle 202, further ensuring the stability of the buckle 202's movement. Both sides of the limiting plate 2044 and the rotating shaft 2043 are fixed to the inner wall of the bracket 2045, making the entire device structure more stable. A spring is fixed on the other side of the buckle 202. 2046. The other end of the spring 2046 is fixed to the inner wall of the bracket 2045. The bracket 2045 provides reliable support for the spring 2046. When the pressing plate 2041 is pressed, causing the latch 202 to move outward of the clamping frame 201, the terminal can be placed inside the clamping frame 201. At this time, the spring 2046 is compressed and contracts, accumulating elastic potential energy. When the position of the terminal is determined, the pressing plate 2041 is released, and the spring 2046 will use its own elasticity to drive the latch 202 to move inward of the clamping frame 201, thereby firmly fixing the terminal. When it is necessary to separate the terminal, simply press the pressing plate 2041 again to separate the latch 202 from the terminal. This structure effectively solves the problem that when the permanent magnet is embedded to fix the terminal, the magnetic field generated by the permanent magnet will attract iron filings and metal dust in the air. These impurities accumulate in the gap of the connector terminal for a long time, forming a "metal bridge", which leads to a short circuit.

[0035] Reference Figure 2 , Figure 4 and Figure 7Each of the multiple fixing mechanisms 3 includes a retaining ring 301, which is installed at the four corners of the mounting plate 1. A base 303 is installed at the outer rear end of the retaining ring 301. A drive shaft 305 is rotatably connected to the front end of the outer wall of the base 303. A triangular knob 310 is fixedly connected to the front end of the outer wall of the drive shaft 305. A bevel gear 306 is fixedly connected to the rear end of the outer wall of the drive shaft 305. Bevel gears 307 are installed on both the left and right sides of the outer wall of the bevel gear 306. The outer walls of the bevel gears 306 mesh with the outer walls of the bevel gears 307. The outer walls of multiple bevel gears 307 are fixedly connected to threaded rods 308 on opposite sides. Threaded brackets 309 are installed on the outer walls of the threaded rods 308. The rear end of the threaded brackets 309 is threadedly connected to the outer wall of the threaded rods 308. The inner walls of the retaining rings 301 have retaining grooves 302 on both the left and right ends. The interior of the retaining grooves 302 is slidably connected to the outer wall of the threaded brackets 309. The front end of the outer wall of the base 303 has limiting grooves 304 on both the left and right sides. The interior of the limiting grooves 304 is slidably connected to the rear end of the outer wall of the threaded brackets 309.

[0036] Specifically, the retaining ring 301 is installed at the four corners of the mounting plate 1, and a base 303 for fixing to the electrical socket is installed on the rear side of each ring. A rotatable drive shaft 305 is installed on the front side of the base 303. A triangular knob 310 is welded to the front end of the drive shaft 305. When the triangular knob 310 is rotated, the power generated is transmitted through the drive shaft 305 to the bevel gear 306 welded on the outside, thereby driving the bevel gear 307, which is tightly meshed with the bevel gear 306, to rotate. Threaded rods 308 are welded to the outer wall of the bevel gear 307. A threaded bracket 309 is threadedly installed on the outside of the threaded rod 308. The bottom end of the threaded bracket 309 can be... The base 303 slides within the limiting groove 304. Due to the limitation of the limiting groove 304, when the bevel gear 307 drives the threaded rod 308 to rotate, the threaded bracket 309 will move within the limiting groove 304 along the axial diameter direction of the threaded rod 308. When the triangular knob 310 is rotated to move the outer side of the threaded bracket 309 to the retaining groove 302 inside the retaining ring 301, the base 303 and the retaining ring 301 can be fixed. This solves the problem that repeated disassembly of screws will cause wear on the terminal hole threads, stripping of the socket housing screw holes, and difficulty in repairing the screw holes after damage, requiring the entire socket to be replaced. If the screws are severely rusted, forced disassembly will break the screws, making it impossible to remove the terminal connector.

[0037] Reference Figure 1 , Figure 3 and Figure 4 Multiple conductive blocks 4 are fixedly connected at equal intervals in the middle of the mounting plate 1. The conductive blocks 4 are installed inside the clamping frame 201 and are used to connect the socket and the terminal to the circuit.

[0038] Specifically, multiple conductive blocks 4 are fixedly installed in the middle of the mounting plate 1. These conductive blocks 4 can be precisely installed inside the clamping frame 201. Their main function is to serve as a connection medium to connect the socket and the terminal in the circuit, so that the current can pass smoothly and ensure the normal conduction of the circuit.

[0039] Working Principle: Pressing the pressing plate 2041 causes the latch 202 to move vertically, achieving rapid clamping and release of the terminal. Supports 2045 are installed at both the upper and lower ends of the clamping frame 201. Multiple rotating frames 2042, which can slide on top of the supports 2045, are installed on the top of the supports 2045. The bottom of the pressing plate 2041 is welded to the rotating frames 2042. A rotating shaft 2043 installed at the bottom of the rotating frame 2042 can rotate inside. Due to the constraint of the rotating shaft 2043, when the pressing plate 2041 is pressed, the adjacent ends of the rotating frames 2042 move upwards through leverage. This, in turn, causes the latch 202 to move upwards through the connecting action of the steel wire 203. A limiting plate 2044 is installed on the outer wall of the latch 202, allowing the latch 202 to slide inside, further providing stable support for the movement of the latch 202. Both sides of the limiting plate 2044 and the rotating shaft 2043 are fixed to the inner wall of the support 2045. To make the entire device more stable, a spring 2046 is fixed on the other side of the buckle 202, and its other end is fixed to the inner wall of the bracket 2045. The bracket 2045 can provide stable support for the spring 2046. When the pressing plate 2041 is pressed to move the buckle 202 to the outside of the clamping frame 201, the terminal can be placed inside the clamping frame 201. At this time, the spring 2046 is compressed and continues to generate elastic potential energy. When the terminal position is determined, the pressing plate 2041 is released, and the spring 2046 will move the buckle 202 to the inside of the clamping frame 201 through its own elasticity, thereby fixing the terminal. When it is necessary to separate the terminal, simply press the pressing plate 2041 again to separate the buckle 202 from the terminal. This solves the problem that when fixing the terminal by embedding a permanent magnet, the magnetic field generated by the permanent magnet will attract iron filings and metal dust in the air. After accumulating in the gap of the connector terminal for a long time, it will form a "metal bridge" and cause a short circuit.

[0040] The terminal connector is installed in the desired position by rotating the triangular knob 310. Since the retaining ring 301 is installed at the four corners of the mounting plate 1, a base 303 for fixing to the electrical socket is installed on its rear side. A rotatable drive shaft 305 is installed on the front side of the base 303, with the triangular knob 310 welded to its front end. When the triangular knob 310 is rotated, its power is transmitted through the drive shaft 305 to the bevel gear 306 welded to its outer side, thereby driving the bevel gear 307, which meshes tightly with the bevel gear 306, to rotate. Threaded rods 308 are welded to the outer wall of the bevel gear 307. A threaded bracket 309 is threadedly installed on its outer side. The bottom end of the threaded bracket 309 can be opened in the base 303. The threaded bracket 309 slides within the limiting groove 304. Due to the limitation of the limiting groove 304, when the bevel gear 307 drives the threaded rod 308 to rotate, the threaded bracket 309 will move within the limiting groove 304 along the axial diameter direction of the threaded rod 308. When the triangular knob 310 is rotated to move the outer side of the threaded bracket 309 to the retaining groove 302 inside the retaining ring 301, the base 303 and the retaining ring 301 can be fixed. This solves the problem that repeated disassembly of screws will cause wear on the terminal hole threads and stripping of the socket housing screw holes, especially for plastic sockets, where damaged screw holes are difficult to repair and the entire socket needs to be replaced. If the screws are severely rusted, forced disassembly will break the screws, making it impossible to remove the terminal connector.
