Description

Technical Field

[0001] This utility model belongs to the field of terminal block manufacturing technology, and in particular relates to an assembly device for terminal block manufacturing. Background Technology

[0002] The assembly equipment for terminal block manufacturing is a device specifically designed to assemble and fix metal conductors (such as copper strips and inserts), insulating housings, and other auxiliary components according to design requirements.

[0003] When assembling terminal blocks, it is usually necessary to strip the wires of the wire harness, install terminals on the metal wires of the wire harness, and insert the terminals into the connector for assembly and fixation. However, after the wire harness terminals are inserted into the connector, the metal terminals may be too long, resulting in the metal parts being exposed to the outside. When the connector is connected and energized later, workers may accidentally touch the exposed metal terminals, which could lead to electric shock and pose a certain safety risk. Utility Model Content

[0004] The purpose of this invention is to provide an assembly device for producing terminal blocks. Specifically, the assembly mechanism involves installing terminal blocks at the ends of the wire harness, inserting the terminal blocks into square protrusions and into the sockets, and simultaneously pushing two clamping blocks to smoothly insert the terminal blocks into the sockets. The clamping blocks then return to their original position due to spring force, holding the terminal blocks in place. This method effectively shields the terminal blocks, preventing accidental contact by workers. Furthermore, by clamping the terminal blocks, the installation is more stable, preventing them from falling off. This invention also solves the problem of excessively long metal terminals after insertion into connectors, resulting in exposed metal parts. This could lead to electric shock if workers accidentally touch the exposed metal terminals when connecting the connector to power on.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an assembly device for manufacturing terminal blocks, comprising several wire harnesses, wherein the wire harnesses are fitted with a heat-shrink sleeve one and a heat-shrink sleeve two, and further comprising: An assembly mechanism is provided at the end of the wire harness. The assembly mechanism includes an assembly connector and a protective component. The protective component is located on the left side of the assembly connector and includes a square protrusion fixedly connected to the left side of the assembly connector. The square protrusion has two inner limiting grooves inside, and a clamping block is slidably connected inside each inner limiting groove. A spring is also provided inside each inner limiting groove. A protective mechanism is provided on the right side of the assembly joint, and the protective mechanism is used to protect the joint. The wire harnesses are arranged in pairs, and each pair of wire harnesses is black and red. The heat shrink sleeve shrinks and fixes the two wire harnesses by heating.

[0006] Furthermore, a terminal block is installed on the side of the wiring harness facing the assembly connector. Several screws are threaded to the top of the assembly connector, and several sockets are opened on the left side of the assembly connector. The terminal block is inserted into the assembly connector through the sockets. The terminal block is inserted into the square protrusion and into the socket. Then, the operator uses a tool to tighten the screws so that the terminal block is tightly attached to one end of the metal plug. The screws are used to lock and fix the connecting plate inserted into the assembly joint.

[0007] Furthermore, the outer side of the clamping block is set with an incline, and an arc-shaped groove is opened on the side of the clamping block facing the wire harness. The end of the spring facing the clamping block is fixedly connected to the surface of the clamping block, and the end of the spring away from the clamping block is fixedly connected to the inner wall of the inner limiting groove. Since the surface of the clamping block is set with an incline, the terminal block can be smoothly inserted between the two clamping blocks, while pushing the two clamping blocks and squeezing the spring. The spring is used to apply elastic force to the clamping block, and the central groove on the clamping block is adapted to the surface of the wire harness.

[0008] Furthermore, a number of metal plugs are fixedly connected to the right side of the assembly connector. The metal plugs pass through the assembly connector and extend into the socket. The metal plugs inside the socket contact the wiring terminals. The metal plugs are embedded in the assembly connector to make the metal plugs more secure. When the terminal block is tightened by the screw, it will be in close contact with the metal plug.

[0009] Furthermore, the protective mechanism includes a connecting plate disposed on the right side of the assembly joint, a plurality of protective sleeves being fixedly connected to the side of the connecting plate facing the assembly joint, and two connecting straps being fixedly connected to the bottom of the connecting plate, the other end of the connecting straps being fixedly connected to the bottom of the assembly joint; the protective sleeves and collars are inserted and fitted onto the outside of the metal plug to protect the metal plug; The connecting strip is used to connect the connecting plate to the assembly joint.

[0010] Furthermore, the protective sleeve is fitted over the outside of the metal plug and is inserted into the collar. The collar and the protective sleeve are pressed together to fix the protective sleeve in place. The protective sleeve can be disassembled by pulling the connecting plate to detach it from the collar.

[0011] Furthermore, two protruding rings are fixedly connected to the outer surface of the heat shrink sleeve II, and an elastic sleeve is fitted on the outer side of the heat shrink sleeve II, with the elastic sleeve positioned between the two protruding rings; by fitting the elastic sleeve onto the heat shrink sleeve II, multiple wire bundles are bundled together using the elasticity, thereby organizing the wire bundles.

[0012] This utility model has the following beneficial effects: 1. This utility model, through the setting of an assembly mechanism, specifically installs a terminal block at the end of the wire harness, inserts the terminal block into the square protrusion and into the socket, and at the same time pushes the two clamping blocks to smoothly insert the terminal block into the socket. Subsequently, the clamping blocks will return to their original position by the elastic force of the spring and hold the terminal block. This method can cover the terminal block, thereby preventing the operator from accidentally touching the terminal block. Furthermore, by holding the terminal block, the terminal block can be more stable after installation, preventing the terminal block from falling off.

[0013] 2. This utility model features a protective mechanism. Specifically, when the assembly connector is not in use, the protective sleeve covers the outside of the metal plug and is inserted into the collar to shield and protect the metal plug. This method can prevent the metal plug from being damaged by bumps and effectively prevent the metal plug from bending or breaking.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] Please see Figures 1-5 As shown, this utility model is an assembly device for manufacturing terminal blocks, including several wire harnesses 1, with heat shrink sleeves 11 and 12 sleeved on the outside of the wire harnesses 1, and also including: Assembly mechanism 2 is located at the end of wire harness 1. Assembly mechanism 2 includes assembly connector 21 and protective component 24. Protective component 24 is located on the left side of assembly connector 21 and includes a square protrusion 241 fixedly connected to the left side of assembly connector 21. The square protrusion 241 has two inner limiting grooves 242 inside, and a clamping block 243 is slidably connected inside the inner limiting grooves 242. A spring 244 is provided inside the inner limiting grooves 242. By setting up assembly mechanism 2, the wiring terminal 1 is installed at the end of wire harness 1. 3. Insert the terminal block 13 into the square protrusion 241 and into the socket 23. Simultaneously, the terminal block 13 will push the two clamping blocks 243, allowing the terminal block 13 to smoothly insert into the socket 23. Then, the clamping blocks 243 will return to their original position due to the spring force of the spring 244, clamping the terminal block 13. This method can shield the terminal block 13, preventing accidental contact by personnel. Furthermore, clamping the terminal block 13 ensures greater stability after installation, preventing it from falling off. The protective mechanism 3 is located on the right side of the assembly joint 21 and is used to protect the joint. Several wire harnesses 1 are arranged in pairs, and the two wire harnesses 1 in each pair are black and red. The heat shrink sleeve 11 shrinks and fixes the two wire harnesses 1 by heating.

[0020] A terminal block 13 is installed on the side of the wire harness 1 facing the assembly connector 21. Several screws 22 are threadedly connected to the top of the assembly connector 21. Several sockets 23 are opened on the left side of the assembly connector 21. The terminal block 13 is inserted into the assembly connector 21 through the sockets 23. The screws 22 are used to lock and fix the connecting plate 31 inserted into the assembly connector 21.

[0021] The outer side of the clamp 243 is set with an inclined surface. The side of the clamp 243 facing the wire harness 1 has an arc-shaped groove. One end of the spring 244 facing the clamp 243 is fixedly connected to the surface of the clamp 243, and the other end of the spring 244 away from the clamp 243 is fixedly connected to the inner wall of the inner limiting groove 242. The spring 244 is used to apply elastic force to the clamp 243. The flower-shaped groove on the clamp 243 is adapted to the surface of the wire harness 1.

[0022] Several metal plugs 25 are fixedly connected to the right side of the assembly connector 21. The metal plugs 25 pass through the assembly connector 21 and extend into the socket 23. The metal plugs 25 in the socket 23 contact the terminal block 13. After the terminal block 13 is tightened by the screw 22, the terminal block 13 will be in close contact with the metal plugs 25.

[0023] The protective mechanism 3 includes a connecting plate 31 located on the right side of the assembly connector 21. Several protective sleeves 32 are fixedly connected to the side of the connecting plate 31 facing the assembly connector 21. Two connecting straps 33 are fixedly connected to the bottom of the connecting plate 31, and the other end of the connecting straps 33 is fixedly connected to the bottom of the assembly connector 21. When the assembly connector 21 is not in use, the protective sleeves 32 will be placed on the outside of the metal plug 25 and inserted into the collar 26 to cover and protect the metal plug 25. This method can prevent the metal plug 25 from being damaged by bumps and effectively prevent the metal plug 25 from bending or breaking. The connecting straps 33 are used to connect the connecting plate 31 to the assembly connector 21.

[0024] The protective sleeve 32 is fitted onto the outside of the metal plug 25 and is inserted into the collar 26. The collar 26 and the protective sleeve 32 are pressed together to fix the protective sleeve 32.

[0025] Two protruding rings 121 are fixedly connected to the outer surface of the heat shrink sleeve 12. An elastic sleeve 122 is fitted on the outer side of the heat shrink sleeve 12, and the elastic sleeve 122 is positioned between the two protruding rings 121.

[0026] One specific application of this embodiment is: When assembling wire harness 1 and assembly connector 21, wire harness 1 is arranged in pairs, with black and red colors. The black and red wires are spirally wound together, and heat shrink sleeves 11 and 12 are respectively placed on the two wound wire harnesses 1. Heat shrink sleeve 11 shrinks by heating, while heat shrink sleeve 12 does not need to be heated to shrink. Then, the terminal block 13 is installed on the end of the wire harness 1, and the terminal block 13 is inserted into the square protrusion 241 and into the socket 23. When the terminal block 13 contacts the clamp 243... When the clamping blocks 243 are inclined, the terminal 13 can be smoothly inserted between the two clamping blocks 243. Simultaneously, pushing the two clamping blocks 243 causes them to slide within the inner limiting groove 242 and compress the spring 244, allowing the terminal 13 to be smoothly inserted into the socket 23. Subsequently, the clamping blocks 243 return to their original position due to the spring force of the spring 244, clamping the terminal 13. This method effectively shields the terminal 13, preventing accidental contact by personnel. By clamping the terminal block 13, the installation of the terminal block 13 is made more stable, preventing it from falling off. Then, the operator uses tools to tighten the screw 22, ensuring that the terminal block 13 is tightly attached to one end of the metal plug 25, completing the assembly. Next, the other wire harnesses 1 are assembled onto the assembly connector 21 in sequence. Finally, the elastic sleeve 122 is placed on the heat shrink sleeve 12, using its elasticity to bundle the multiple wire harnesses 1, thus organizing the wire harnesses 1. The protruding ring 121 also limits the movement of the elastic sleeve 122. The elastic sleeve 122 is stably fitted onto the heat shrink sleeve 12. When the assembly connector 21 is not in use, the protective sleeve 32 will be fitted over the outside of the metal plug 25 and inserted into the collar 26 to protect the metal plug 25. This method can prevent the metal plug 25 from being damaged by bumps. When it is needed, the protective sleeve 32 can be removed by pulling the connecting plate 31 to detach it from the collar 26. The connecting plate 31 will always be connected to the assembly connector 21 through the connecting strap 33 to prevent loss, thus completing the assembly work.
