Technical Field

[0001] This invention relates to the field of circuit connection technology, and in particular to a multi-purpose terminal block for electrical instruments and meters and its processing equipment. Background Technology

[0002] The core function of a terminal block is to serve as a standardized connection point between wires and devices, and between wires themselves, in electrical, electronic, and circuit applications, enabling stable transmission of current or electrical signals. Simply put, it is a special component in a circuit that is specifically designed to "connect wires," replacing the simple connection methods of direct soldering or winding, and is a fundamental element of electrical connections.

[0003] Existing input / output terminals used in electrical instruments are designed with limited functionality during production. When connecting circuits, they can only be used with alligator clip wires, banana plug wires, or U-shaped terminal wires, resulting in poor compatibility, which is especially troublesome when connecting multiple circuits. Summary of the Invention

[0004] This invention provides a multi-purpose terminal block for electrical instruments and meters and its processing equipment, which can solve the problem of poor adaptability of existing terminal blocks in the prior art.

[0008] As a further technical solution of the present invention, each of the limiting mechanisms includes multiple guide posts fixed on both sides of the sliding seat. One end of each guide post movably passes through the connecting arm and is fixed with a connecting disc II. Multiple springs are fixed between the connecting disc II and the connecting arm, and each spring is movably sleeved on the outer surface of the guide post.

[0009] As a further technical solution of the present invention, two pairs of connecting blocks are fixed on one side of the mesh frame, and an abutting wheel is rotatably arranged between each pair of connecting blocks. Multiple abutting blocks that cooperate with the abutting wheels are fixed on the inner wall of the cleaning tank.

[0010] As a further technical solution of the present invention, multiple rotating shafts are rotatably arranged on the inner wall of the cleaning tank. Multiple propeller blades are fixed on the outer surface of each rotating shaft. One end of each rotating shaft rotatably passes through the cleaning tank and is fixedly fitted with a one-way ratchet bearing. A gear ring is fixed on the outer surface of the one-way ratchet bearing. A connecting plate is fixed on the lower end face of the lifting plate. A rack is fixed on both sides of the connecting plate to cooperate with the gear ring. A U-shaped guide cover is fixed on the outer wall of the cleaning tank.

[0011] As a further technical solution of the present invention, electric slide rails are provided on both sides of the cleaning tank, and an electric slider is slidably provided on each electric slide rail. A telescopic cylinder seat is fixed on the upper end face of each electric slider, and a telescopic arm is movably provided inside the telescopic cylinder seat. Two L-shaped connecting frames are symmetrically fixed on the upper end face of the lifting plate, and the upper end of the telescopic arm is fixedly connected to the L-shaped connecting frame.

[0012] As a further technical solution of the present invention, a rack is fixed on one side of each telescopic arm, a notch is provided on the telescopic cylinder seat to cooperate with the rack, a drive box is fixed on the outer side wall of the telescopic cylinder seat, a drive gear is rotatably provided on the drive box, and the drive gear meshes with the rack.

[0013] As a further technical solution of the present invention, an electric push rod is fixedly installed through the upper end face of the first lifting plate, and a second lifting plate is fixed at the lower end of the electric push rod. The second lifting plate is movably installed between two connecting arms. Two top mounting slots are opened on the lower end face of the second lifting plate, and an electric guide rail is fixed in each top mounting slot. The same air blowing hood is slidably installed on the two electric guide rails. The air outlet end of the air blowing hood faces downward. An air supply unit for use with the air blowing hood is provided on the first lifting plate.

[0014] As a further technical solution of the present invention, the air supply unit includes an air supply pump fixed to an upper end face of the lifting plate, and a telescopic air pipe is provided between the air supply pump and the air blowing hood.

[0015] The beneficial effects of this invention are: 1. When used with alligator clip wires, the alligator clips can be directly clamped onto the outer surface of the second copper post. When used with banana plug wires, the plug end of the banana plug wire can be directly inserted into the insertion slot. When used with U-shaped terminal wires, the PP knob can be rotated clockwise to move it away from the first circular pad, and then the U-shaped terminal can be placed between the first circular pad and the PP knob. Then, the PP knob can be rotated counterclockwise to move it closer to the first circular pad, thereby clamping and fixing the U-shaped terminal. This method is highly versatile and can be used simultaneously with alligator clip wires, banana plug wires, and U-shaped terminal wires as needed.

[0016] 2. In the initial state, the wire mesh frame is outside the cleaning tank. The limiting mechanism limits and fixes the connecting plate, thereby limiting and fixing the connecting column and the wire mesh frame. In this state, the wire mesh frame will not flip. The operator pours the multiple copper column bodies to be cleaned into the wire mesh frame. Then, the lifting plate moves the wire mesh frame into the cleaning tank to clean the oil and processing debris on the surface of the copper column bodies. Then, the lifting plate moves the wire mesh frame and the cleaned copper column bodies to the outside of the cleaning tank. Then, the operator causes the limiting mechanism to release the limiting and fixing of the connecting plate, and then flips the wire mesh frame to facilitate the unloading of the copper column bodies located in the wire mesh frame.

[0017] 3. After the lifting plate moves the mesh frame into the cleaning tank, the lifting plate moves the connecting arm and the mesh frame downwards. The mesh frame moves the connecting block and the contact wheel downwards together. As the contact wheel moves downwards, it passes through each contact block. When the contact wheel passes through the contact block, the contact block pushes the contact wheel, the mesh frame and the sliding seat to move horizontally. Then, in conjunction with the spring, the sliding seat and the mesh frame will also move horizontally back and forth as they move vertically downwards, assisting in the cleaning operation.

[0018] 4. When the lifting plate moves the mesh frame into the cleaning tank, the connecting plate and rack move downwards together as the lifting plate moves downwards. As the rack moves downwards, it drives the rotating shaft to rotate through the cooperation of the gear ring and the one-way ratchet bearing, thereby driving the propeller blades to rotate. As the mesh frame moves downwards, the debris that has been cleaned inside the mesh frame moves away from the mesh frame. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Reference Figures 1-12 A multi-purpose terminal block for electrical instruments includes a copper terminal body 100, which includes a first copper terminal portion 101, a second copper terminal portion 102, and a third copper terminal portion 103. One end of the third copper terminal portion 103 has an insertion groove 104, and the outer surface of the third copper terminal portion 103 has a threaded groove. A PP knob 105 is threaded onto the outer surface of the third copper terminal portion 103. A circular washer 106 is fixedly fitted onto the outer surface of the second copper terminal portion 102. The diameter of the first copper terminal portion 101 is smaller than the diameter of the second copper terminal portion 102. The outer surface of the first copper terminal portion 101 has a threaded groove 2, and a circular washer 2 107 is movably fitted onto the outer surface of the first copper terminal portion 101. A mounting nut 108 is threaded onto the outer surface of the first copper terminal portion 101.

[0023] When used with alligator clip wires, the alligator clips can be directly clamped onto the outer surface of the second copper post 102. When used with banana plug wires, the plug end of the banana plug wire can be directly inserted into the insertion slot 104. When used with U-shaped terminal wires, the PP knob 105 can be rotated forward to move it away from the circular pad 106, and then the U-shaped terminal can be placed between the circular pad 106 and the PP knob 105. Then, the PP knob 105 can be rotated in the opposite direction to move it closer to the circular pad 106, thereby clamping and fixing the U-shaped terminal. This solution is highly versatile and can be used simultaneously with alligator clip wires, banana plug wires, and U-shaped terminal wires as needed.

[0024] The installation and connection of this application with existing electrical instruments and meters are existing technologies, and will not be described in detail here.

[0025] An anti-detachment buckle is added between the third copper column 103 and the PP knob 105 to prevent the PP knob 105 from falling off and being lost.

[0026] This invention also discloses a multi-purpose terminal block processing equipment for electrical instruments, used to produce the aforementioned multi-purpose terminal blocks for electrical instruments. The equipment includes a cleaning tank 200, which is fixed to the ground and contains cleaning water. A lifting plate 201 is movably mounted on the cleaning tank 200. Two connecting arms 202 are symmetrically fixed to the lower end face of the lifting plate 201. Each connecting arm 202 has a sliding groove 203 on its opposite surface, and a sliding seat 204 is slidably mounted in each sliding groove 203. A mesh frame 205 is provided between the seats 204. Connecting posts 206 are fixed on both sides of the mesh frame 205. One end of each connecting post 206 rotatably passes through the sliding seat 204 and is fixed with a connecting plate 207. A limiting mechanism is provided on the sliding seat 204 to cooperate with the connecting plate 207. A guiding mechanism is provided on the sliding groove 203 to cooperate with the sliding seat 204. An ultrasonic cleaning mechanism is provided inside the cleaning tank 200. The ultrasonic cleaning mechanism is existing technology. An inlet pipe and an outlet pipe are provided on the cleaning tank 200. Valves are provided on both the inlet pipe and the outlet pipe.

[0027] During the machining process, the surface of the copper column body 100 will be covered with oil (cutting fluid) and machining debris, so the copper column body 100 needs to be cleaned.

[0028] In the initial state, the wire mesh frame 205 is outside the cleaning tank 200. The limiting mechanism limits and fixes the connecting plate 207, thereby limiting and fixing the connecting column 206 and the wire mesh frame 205. In this state, the wire mesh frame 205 will not flip. The worker pours the multiple copper column bodies 100 to be cleaned into the wire mesh frame 205. Then, the lifting plate 201 drives the wire mesh frame 205 into the cleaning tank 200 to clean the oil and processing debris on the surface of the copper column bodies 100. Then, the lifting plate 201 drives the wire mesh frame 205 and the cleaned copper column bodies 100 to move outside the cleaning tank 200. Then, the worker causes the limiting mechanism to release the limiting fixation of the connecting plate 207 and flips the wire mesh frame 205 to facilitate the unloading of the copper column bodies 100 located in the wire mesh frame 205.

[0029] Each limiting mechanism includes a connecting seat 208 fixed to one side of the sliding seat 204. A plug 209 is movably disposed below the connecting seat 208. A slot 210 for use with the plug 209 is opened on the outer surface of the connecting plate 207. Two guide rods 211 are symmetrically fixed on the upper end face of the plug 209. The upper end of each guide rod 211 movably passes through the connecting seat 208. A threaded rod 212 is rotatably disposed on the upper end face of the plug 209. The upper end of the threaded rod 212 is threaded through the connecting seat 208 and fixed with a handwheel 213.

[0030] In the initial state, the insert 209 is located in the slot 210, thereby restricting the rotation of the connecting plate 207, the connecting post 206 and the mesh frame 205. When it is necessary to release the rotation of the connecting plate 207, the operator rotates the handwheel 213 and the threaded rod 212 in the forward direction, thereby causing the insert 209 to move upward away from the slot 210.

[0031] Each limiting mechanism includes multiple guide posts 214 fixed on both sides of the sliding seat 204. One end of each guide post 214 movably passes through the connecting arm 202 and is fixed with a connecting plate 215. Multiple springs 216 are fixed between the connecting plate 215 and the connecting arm 202. Each spring 216 is movably sleeved on the outer surface of the guide post 214.

[0032] The guide post 214 is used to confine the sliding seat 204 within the sliding through groove 203.

[0033] Two pairs of connecting blocks 217 are fixed on one side of the wire mesh frame 205. Each pair of connecting blocks 217 is rotatably provided with a contact wheel 218. Multiple contact blocks 219 that cooperate with the contact wheels 218 are fixed on the inner wall of the cleaning tank 200.

[0034] When the lifting plate 201 drives the mesh frame 205 into the cleaning tank 200, the lifting plate 201 drives the connecting arm 202 and the mesh frame 205 to move downward. The mesh frame 205 drives the connecting block 217 and the abutment wheel 218 to move downward together. During the downward movement, the abutment wheel 218 passes through each abutment block 219. When the abutment wheel 218 passes through the abutment block 219, the abutment block 219 will push the abutment wheel 218, the mesh frame 205 and the sliding seat 204 to move horizontally. Then, in conjunction with the spring 216, the sliding seat 204 and the mesh frame 205 will also undergo a reciprocating horizontal movement from side to side during the vertical downward movement, assisting in the cleaning operation.

[0035] During the cleaning process, the lifting plate 201 causes the wire mesh frame 205 to move up and down several times within the cleaning box 200.

[0036] Multiple rotating shafts 220 are rotatably mounted on the inner wall of the cleaning tank 200. Multiple propeller blades 221 are fixed on the outer surface of each rotating shaft 220. One end of each rotating shaft 220 rotatably passes through the cleaning tank 200 and is fixedly fitted with a one-way ratchet bearing. A gear ring 222 is fixed on the outer surface of the one-way ratchet bearing. A connecting plate 223 is fixed on the lower end face of the lifting plate 201. A rack 224 that matches the gear ring 222 is fixed on both sides of the connecting plate 223. A U-shaped guide cover 225 is fixed on the outer wall of the cleaning tank 200.

[0037] When the lifting plate 201 moves the mesh frame 205 into the cleaning tank 200, as the lifting plate 201 moves downward, it will move the connecting plate 223 and the rack 224 downward together. As the rack 224 moves downward, it will drive the rotating shaft 220 to rotate through the cooperation of the gear ring 222 and the one-way ratchet bearing, thereby driving the propeller blades 221 to rotate. As the mesh frame 205 moves downward, the debris that has been cleaned out inside the mesh frame 205 will move away from the mesh frame 205.

[0038] Electric slide rails 226 are provided on both sides of the cleaning tank 200. Electric sliders 227 are slidably mounted on each electric slide rail 226. Telescopic cylinder seats 228 are fixed on the upper end face of each electric slider 227. Telescopic arms 229 are movably mounted inside the telescopic cylinder seats 228. Two L-shaped connecting frames 230 are symmetrically fixed on the upper end face of the lifting plate 201. The upper end of the telescopic arm 229 is fixedly connected to the L-shaped connecting frame 230.

[0039] Both the electric slide rail 226 and the electric slider 227 are existing technologies. Through the cooperation of the electric slide rail 226 and the electric slider 227, the telescopic cylinder seat 228, the telescopic arm 229, the L-shaped connecting frame 230 and the lifting plate 201 are moved horizontally.

[0040] Each telescopic arm 229 has a rack 231 fixed on one side. The telescopic cylinder base 228 has a notch 232 for use with the rack 231. A drive box 233 is fixed on the outer wall of the telescopic cylinder base 228. A drive gear is rotatably mounted on the drive box 233 and meshes with the rack 231.

[0041] The drive box 233 is existing technology. The drive box 233 causes the drive gear to rotate, thereby driving the rack 231 and the telescopic arm 229 to move up and down. This is existing technology.

[0042] An electric push rod 234 is fixedly installed through the upper end of the lifting plate 201. A lifting plate 235 is fixed to the lower end of the electric push rod 234. The lifting plate 235 is movably installed between the two connecting arms 202. Two top mounting slots are opened on the lower end of the lifting plate 235. An electric guide rail 236 is fixed in each top mounting slot. The same air blowing hood 237 is slidably installed on the two electric guide rails 236. The air outlet end of the air blowing hood 237 faces downward. An air supply unit is provided on the lifting plate 201 to cooperate with the air blowing hood 237.

[0043] After the copper column body 100 located in the mesh frame 205 is cleaned, the lifting plate 201 causes the mesh frame 205 to move upward, causing the mesh frame 205 to detach from the liquid surface of the cleaning water in the cleaning tank 200. Then the air supply unit works, causing the air blowing hood 237 to blow air downward, and the air blowing hood 237 is moved horizontally by the electric guide rail 236 to cooperate in the draining treatment of the copper column body 100 located in the mesh frame 205.

[0044] The air supply unit includes an air pump 238 fixed to the upper surface of the lifting plate 201, and a telescopic air pipe 239 is provided between the air pump 238 and the air blowing hood 237.

[0045] When the air pump 238 is working, it generates airflow, which is delivered to the air blowing hood 237 through the telescopic air pipe 239.

[0046] When using this invention, when used with alligator clip wires, the alligator clips can be directly clamped onto the outer surface of the second copper pillar 102. When used with banana plug wires, the plug end of the banana plug wire can be directly inserted into the insertion groove 104. When used with U-shaped terminal wires, the PP knob 105 can be rotated forward to move it away from the circular pad 106, and then the U-shaped terminal can be placed between the circular pad 106 and the PP knob 105. Then, the PP knob 105 can be rotated in the opposite direction to move it closer to the circular pad 106, thereby clamping and fixing the U-shaped terminal. This invention is highly versatile and can be used simultaneously with alligator clip wires, banana plug wires, and U-shaped terminal wires as needed. During the production and processing of the copper column body 100, when cleaning the copper column body 100, in the initial state, the mesh frame 205 is outside the cleaning box 200. The limiting mechanism limits and fixes the connecting plate 207, thereby limiting and fixing the connecting column 206 and the mesh frame 205. In this state, the mesh frame 205 will not flip. The worker pours the multiple copper column bodies 100 to be cleaned into the mesh frame 205. Then, the lifting plate 201 drives the mesh frame 205 into the cleaning box 200 to clean the oil and processing debris on the surface of the copper column body 100. Then, the lifting plate 201 drives the mesh frame 205 and the cleaned copper column body 100 to move outside the cleaning box 200. Then, the worker causes the limiting mechanism to release the limiting and fixing of the connecting plate 207, and then flips the mesh frame 205, so as to facilitate the unloading of the copper column body 100 located in the mesh frame 205. When the lifting plate 201 drives the mesh frame 205 into the cleaning tank 200, the lifting plate 201 drives the connecting arm 202 and the mesh frame 205 to move downward. The mesh frame 205 drives the connecting block 217 and the abutment wheel 218 to move downward together. During the downward movement, the abutment wheel 218 will pass through each abutment block 219. When the abutment wheel 218 passes through the abutment block 219, the abutment block 219 will push the abutment wheel 218, the mesh frame 205 and the sliding seat 204 to move horizontally. Then, in conjunction with the spring 216, the sliding seat 204 and the mesh frame 205 will also undergo a reciprocating horizontal movement from side to side during the vertical downward movement, which assists in the cleaning operation. When the lifting plate 201 moves the mesh frame 205 into the cleaning tank 200, as the lifting plate 201 moves downward, it will move the connecting plate 223 and the rack 224 downward together. As the rack 224 moves downward, it will drive the rotating shaft 220 to rotate through the cooperation of the gear ring 222 and the one-way ratchet bearing, thereby driving the propeller blades 221 to rotate. As the mesh frame 205 moves downward, the debris that has been cleaned out inside the mesh frame 205 will move away from the mesh frame 205.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
