Description

Technical Field

[0001] This invention belongs to the field of electric welding equipment technology, and particularly relates to an electric welding terminal block. Background Technology

[0002] An electric welding machine uses a high-temperature electric arc generated when positive and negative electrodes are momentarily short-circuited to melt the welding rod and the material being welded, thus joining the two objects together. Welding machines can use different power sources, including AC and DC power. The voltage and current of AC power change over time, while DC power remains stable. In AC power, the arc temperature and energy are typically lower, while DC power can generate a stronger arc, resulting in more stable and efficient welding.

[0003] When using electric welding, welding wire is indispensable. The welding wire is heated and melted onto the material to be welded to achieve the welding purpose. This process requires a power source to heat the welding wire. Typically, the welding wire uses an appropriate electrical connection structure to connect to the power source. This electrical connection structure includes commonly used welding terminals. Currently, the terminals are usually installed manually by winding the wire around the terminal and then securing it with bolts or similar structures to ensure a stable connection. Firstly, while this installation method can fully connect the wire to the terminal, it is cumbersome and inconvenient for connection and disassembly. Secondly, existing terminals are often directly exposed to the outside. While this facilitates connection and disconnection to some extent, direct exposure makes them susceptible to damage from the external environment or human factors, and also poses a certain degree of danger. Finally, during use, if the wire furthest from the terminal is subjected to external tension, the connection between the wire and the terminal can easily loosen, or even break completely, lacking appropriate safety protection measures. Therefore, in view of the above-mentioned problems, this technical solution proposes an electric welding terminal block. Summary of the Invention

[0004] The purpose of this invention is to provide an electric welding terminal block, which aims to solve the following problems.

[0005] This invention is implemented as follows: an electric welding terminal block includes a terminal block base, which is used in conjunction with an electric welding machine. The terminal block includes an upper terminal block and a lower terminal block, which are electrically connected by a plug-in connection. A power line is connected to one end of the upper terminal block, through which current and signals are input to the upper terminal block. Three sets of electrical connection post inserts are arranged in a straight line at equal intervals on one side of the top of the lower terminal block. Three sets of electrical connection post kits, which are electrically connected to the electrical connection post inserts, are provided on the bottom of the upper terminal block corresponding to the electrical connection post inserts. Wire holes are provided on the sidewalls of the upper and lower terminal blocks corresponding to the electrical connection post kits and electrical connection post inserts. The inner ends of the wire holes are connected to wires located inside the upper and lower terminal blocks. The connection channel has wire positioning grooves at its end, which are opened inside the upper and lower column plates. The electrical connection post kit and electrical connection post plug are each provided with a terminal slot in the upper and lower column plates respectively. The electrical connection post kit and electrical connection post plug are installed in the terminal slot. The terminal slot is connected to the wire positioning groove, and the terminal of the electrical connection post kit and electrical connection post plug extends into the wire positioning groove. The end of the wire that is input into the wire positioning groove along the wire connection channel is connected to the terminal of the electrical connection post kit or electrical connection post plug. Then, when the upper and lower column plates are installed, the corresponding electrical connection post kit and electrical connection post plug are plugged in to connect to the outside, thereby realizing the circuit connection of the electric welding end. The clamping mechanism is telescopically set on the side of the wire positioning groove opposite to the electrical connection post kit or electrical connection post plug terminal. The clamping mechanism moves relative to the inside of the wire positioning groove. Because it clamps and positions the wire connected to the electrical connection post kit or electrical connection post plug terminal, the end of the clamping mechanism away from the wire positioning groove extends to the outside of the upper or lower post plate. That is, the lateral movement of the clamping mechanism is manually controlled. The positioning and protection mechanism is installed in the horizontal section inside the wire connection channel. The positioning and protection mechanism is connected to the clamping mechanism. When the clamping mechanism moves, it simultaneously drives the positioning and protection mechanism to prevent the wires placed inside the wire connection channel from being pulled and positioned. This provides a stable and controllable static positioning state for the wires after they are connected to the electrical connection post kit and electrical connection post plug, protecting the safe connection and operation of the wires with the electrical connection post kit and electrical connection post plug.

[0006] This invention provides an electric welding terminal block. By placing the terminal blocks connected to the circuit inside the upper and lower plate respectively, and then extending one end of the terminal block to the outside of the opposite side of the upper and lower plate, the electrical connection and separation of the terminal blocks on both sides can be controlled simultaneously by controlling the upper and lower plate to move closer and separate. That is, by controlling the installation and removal of the upper and lower plate, the connection and separation of the welding circuit can be realized simultaneously, which is convenient for users to operate. Furthermore, placing the terminal block inside the upper and lower plate can reduce the influence of the external environment and improve safety. By setting wire positioning grooves inside the upper and lower column plates, and connecting wire connection channels on one side of the wire positioning grooves, and by setting a clamping mechanism inside one side of the wire positioning grooves to increase the stability of the connection between the wire and the electrical connection post kit or electrical connection post plug, and then setting a positioning protection mechanism inside the wire connection channel to press the wire and increase its anti-pull ability, and the positioning protection mechanism and the clamping mechanism operate synchronously, the compactness of the structure and the efficiency of transmission are further improved.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-6The diagram shows a structural representation of an electric welding terminal block according to an embodiment of the present invention. The terminal block includes a terminal block base, which is used in conjunction with an electric welding machine. The terminal block includes an upper terminal block 10 and a lower terminal block 11, which are electrically connected by a plug-in connection. One end of the upper terminal block 10 is connected to a power line 12, through which current and signals are input to the upper terminal block 10. Three sets of electrical connection post inserts 18 are arranged in a straight line at equal intervals on one side of the top of the lower terminal block 11. Three sets of electrical connection post kits 17, which are plugged into and electrically connected to the electrical connection post inserts 18, are provided on the bottom of the upper terminal block 10 corresponding to the electrical connection post kits 17 and the electrical connection post inserts 18. Wire holes 16 are provided on the sidewalls of the upper terminal block 10 and the lower terminal block 11 on the corresponding side of the electrical connection post kits 17 and the electrical connection post inserts 18. The inner ends of the wire holes 16 are connected to wires opened inside the upper terminal block 10 and the lower terminal block 11. The connection channel 20 is connected to the wire positioning groove 23 opened inside the upper column plate 10 and the lower column plate 11. The electrical connection post kit 17 and the electrical connection post plug 18 are respectively provided with terminal post grooves 19 in the upper column plate 10 and the lower column plate 11. The electrical connection post kit 17 and the electrical connection post plug 18 are installed in the terminal post grooves 19. The terminal post grooves 19 are connected to the wire positioning groove 23, and the terminals inside the electrical connection post kit 17 and the electrical connection post plug 18 extend into the wire positioning groove 23. The wire end that is input along the wire connection channel 20 into the wire positioning groove 23 is connected to the terminal of the electrical connection post kit 17 or the electrical connection post plug 18. Then, when the upper column plate 10 and the lower column plate 11 are installed, the corresponding electrical connection post kit 17 and the electrical connection post plug 18 are plugged in and connected to the outside, thereby realizing the circuit connection of the electric welding end. The clamping mechanism is telescopically set on the side of the wire positioning groove 23 opposite to the terminal of the electrical connection post kit 17 or electrical connection post plug 18. The clamping mechanism moves relative to the inside of the wire positioning groove 23 to clamp and position the wire connected to the terminal of the electrical connection post kit 17 or electrical connection post plug 18. The end of the clamping mechanism away from the wire positioning groove 23 extends to the outside of the upper post plate 10 or lower post plate 11, that is, the lateral movement of the clamping mechanism is manually controlled. The positioning and protection mechanism is set in the horizontal section area inside the wire connection channel 20. The positioning and protection mechanism is connected to the clamping mechanism. That is, when the clamping mechanism moves, it synchronously drives the positioning and protection mechanism to anti-pull positioning the wire placed inside the wire connection channel 20. This provides a stable and controllable static positioning state for the wire after it is connected to the electrical connection post kit 17 and the electrical connection post plug 18, protecting the safe connection and operation of the wire to the electrical connection post kit 17 and the electrical connection post plug 18. In this process, the wire is first passed through the wire hole 16 and extended along the wire connection channel 20 into the wire positioning groove 23. Then, its end is connected to the terminal inside the electrical connection post kit 17 and electrical connection post plug 18. The clamping mechanism is then manually moved to clamp and fix the wire inside the wire positioning groove 23 to the terminal of the electrical connection post kit 17 and electrical connection post plug 18. Simultaneously, the positioning and protection mechanism further positions and protects the wire in the horizontal section inside the wire connection channel 20 from pulling. During subsequent welding, the upper and lower pin plates 10 are moved directly, and the upper pin plate is secured using the connection between the electrical connection post kit 17 and electrical connection post plug 18. 10. The corresponding circuit inside the lower column plate 11 is electrically connected to form a complete electric welding circuit. That is, through the plug-in electrical connection of the electric connection column kit 17 and the electric connection column plug 18 on the opposite side of the upper column plate 10 and the lower column plate 11, it is convenient to control the connection and disconnection of the corresponding circuit, and to control the start and stop of electric welding. The wiring terminals of the electric connection column kit 17 and the electric connection column plug 18 are set inside the upper column plate 10 and the lower column plate 11 to connect with the wires. Then, in conjunction with the clamping mechanism, the connection stability is increased. On the basis of the clamping mechanism, a positioning protection mechanism is added to further increase the anti-pulling function of the wires, and fully improve the safety of the wires after they are connected to the electric connection column kit 17 and the electric connection column plug 18.

[0025] In this embodiment of the invention, the electrical connection post kit 17 and the electrical connection post plug 18 are respectively connected to a neutral wire, a live wire, and a ground wire, thus realizing the circuit connection of the normal terminal block. The top of the wire hole 16 can extend to the outside of the upper post plate 10 and the lower post plate 11 for connection with the wire, or it can extend to the inner wall of the upper post plate 10 and the lower post plate 11 for connection with the wires distributed inside the upper post plate 10 and the lower post plate 11. The distribution position of the wire at the wire hole 16 can be determined according to actual needs. The clamping mechanism and the positioning protection mechanism are provided with an insulating layer on the side that contacts the wire to prevent the current at the terminal of the electrical connection post kit 17 and the electrical connection post plug 18 and the wire from transferring into the clamping mechanism and affecting the normal operation of the circuit. Specifically, to increase the stability of the upper plate 10 and the lower plate 11 during long-term operation after plugging them together, a connecting plate 15 is installed on one side of the upper plate 10 and the lower plate 11, extending outward. The connecting plates 15 on both sides are fixed by fastening bolts. The use of connecting plates 15 and fastening bolts is selective and depends on the actual situation. At the same time, signal output plugs 14 and signal access sockets 13 are respectively provided on the opposite sides of the upper plate 10 and the lower plate 11. While the electrical connection post kit 17 and the electrical connection post plug 18 are fully plugged in, the signal output plugs 14 and the signal access sockets 13 are embedded and connected, that is, signal transmission connection is performed on both sides at the same time.

[0026] In one embodiment of the present invention, see [reference] Figures 6-11 The electrical connector assembly 17 and the electrical connector plug-in 18 have similar structures, both including a rectangular nut 37, an internally threaded cylinder 36 threaded to the nut 37, and a stud 35 threaded to the internally threaded cylinder 36. One end of the stud 35 has an internal hexagonal screw hole. By rotating the internal hexagonal screw hole, the stud 35 moves axially along the inside of the internally threaded cylinder 36. The end of the stud 35 furthest from its internal hexagonal screw hole is horizontally positioned towards the wire positioning groove 23, and this end is used as the terminal for the electrical connector assembly 17 and the electrical connector plug-in 18. The wire end, which is transferred along the wire connection channel 20 to the wire positioning groove 23, is wound and connected to the end of the stud 35. This connection method can be achieved by first extending the end of the wire to the inside of the internal threaded cylinder 36, and then controlling the movement of the stud 35 by controlling the internal hexagonal screw hole. The wire end is initially fixed to the outside of the stud 35 by the thread movement clamping between the stud 35 and the internal threaded cylinder 36. Then, with the cooperation of the clamping mechanism and the positioning and protection mechanism, the wire is finally safely connected and positioned. The nut 37 on the electrical connector assembly 17 is connected to the electrical connector 39 on the side facing the outside of the bottom of the upper plate 10, and the nut 37 on the electrical connector plug 18 is connected to the electrical connector 40 on the side facing the outside of the top of the lower plate 11. That is, by plugging the electrical connector 39 and the electrical connector 40, the connection and disconnection of the corresponding circuits inside the upper plate 10 and the lower plate 11 can be realized. In other words, the synchronous connection and disconnection of the circuit can be realized by the relative movement and installation and separation of the upper plate 10 and the lower plate 11. It should be noted that the stud 35, internal threaded sleeve 36, nut 37, electrical connector sleeve 39, electrical connector 40 and other structures are all made of conductive metal materials, so that the current can be transmitted smoothly after connection. Such metal materials can be copper, aluminum and other materials with excellent conductivity.

[0027] Multiple slots are provided on the annular sidewall of the electric connector 39. The slots, combined with the toughness of the material of the electric connector 39, allow it to fit snugly into the telescopic rod 30, ensuring a stable connection while also enabling quick separation.

[0028] As a preferred embodiment of the present invention, see [reference]. Figure 4 , Figure 5 , Figure 15The clamping mechanism includes a clamping plate 34 telescopically mounted on one side of the wire positioning groove 23. A screw 31 is rotatably connected to the end of the clamping plate 34 away from the wire positioning groove 23 via a rotating shaft 33. An internally threaded plate 32, fixed inside the upper or lower column plate 11, is threadedly connected to the outer side of the screw 31. A telescopic rod 30 is connected to the end of the screw 31 away from the clamping plate 34. A telescopic sleeve 29 is fitted onto the outer side of the telescopic rod 30. A positioning key is installed on the circumferential outer wall of the telescopic rod 30. A slide rail is provided on the inner wall of the telescopic sleeve 29 corresponding to the positioning key, allowing the positioning key to move along the slide rail. A column shaft 28 is connected to the end of the telescopic sleeve 29 away from the screw 31. A rotating rod 26 is connected to the end of the column shaft 28. The outer end of the rotating rod 26 extends into the rotating handle groove 25 on the outer side wall of the upper column plate 10 or the lower column plate 11 and is equipped with a rotating handle 24. The rotating rod 26 is rotated by manually rotating the rotating handle 24. Then, under the connection of the column shaft 28, the telescopic sleeve 29 is rotated synchronously. Then, under the connection of the positioning key and the slide rail, the screw 31 is controlled to rotate inside the internal thread plate 32 and move laterally. Then, under the connection of the rotating shaft 33, the clamping plate 34 is controlled to move laterally, so as to clamp and fix the wire on the stud 35 or release it away. That is, according to the needs of applying the connection, the connection between the wire and the electrical connection post kit 17, electrical connection post plug 18, etc. is tightened and released by manual control. Specifically, the clamping plate 34 is configured as a recessed semi-circular arc structure, which is fitted into contact with the end of the stud 35. That is, the clamping plate 34 is controlled to move toward the end of the stud 35. By fitting the clamping plate 34 into contact with the outside of the stud 35, the end of the wire placed on the stud 35 is clamped and fixed. The clamping plate 34 is made of rubber, which has an insulating function. At the same time, it prevents damage to the wire due to its high hardness when directly contacting the end of the stud 35. The elasticity of the rubber and the lateral thrust are used to keep the clamping plate 34 fully clamping the wire on the stud 35. The upper column plate 10 or lower column plate 11 corresponding to the rotating rod 26 has a rod hole 27. The rotating rod 26 is placed inside the rod hole 27 and rotates. Multiple support rings are evenly installed inside the rod hole 27 and fitted on the rotating rod 26 to keep the rotating rod 26 stable when the rotating handle 24 is manually rotated. At the same time, multiple support rod sleeves are fitted on the column shaft 28 to control the column shaft 28 to rotate smoothly.

[0029] As a preferred embodiment of the present invention, see [reference]. Figures 12-14The positioning and protection mechanism includes multiple sets of longitudinal clamping members evenly spaced inside the wire connection channel 20 along its horizontal length. The bottom of the longitudinal clamping member is connected to a transmission module, which is connected to the corresponding lower column shaft 28. That is, when the manually controlled rotating rod 26 rotates to drive the clamping plate 34 to approach the stud 35 to clamp and fix the end of the wire, the transmission module is driven to run simultaneously, driving the longitudinal clamping member at the top to clamp and position the wire placed inside the wire connection channel 20. That is, when the clamping plate 34 moves to the maximum clamping position, the longitudinal clamping member also moves synchronously to the upper and lower sides of the wire to longitudinally press it, thereby reducing the pulling force when the wire is subjected to tension. The longitudinal clamping component includes two arc-shaped pressure plates 42 that are symmetrically distributed vertically. The wire connection channels 20 corresponding to the pressure plates 42 are provided with channels for the vertical movement of the pressure plates 42. Both ends of the pressure plates 42 are connected to lifting components through connecting blocks 41. The bottom ends of the lifting components are rotatably connected to the transmission module. That is, the operation of the transmission module synchronously controls the lifting components on both sides to drive the pressure plates 42 to move vertically relative to each other. The lifting assembly includes a nut fixed to the connecting block 41. A vertical lead screw 43 is threaded onto the nut. The upper and lower lead screws 43 are fixed together with opposite tooth directions. Each nut is equipped with a guide device to limit its rotation. A connecting rod 44 is installed at the bottom of the lower lead screw 43. The connecting rod 44 is connected to the transmission module. When the connecting rod 44 rotates, it synchronously drives the two lead screws 43 above it to rotate, and then synchronously drives the two nuts to move relative to each other. In turn, under the connection of the connecting block 41, the pressure plate 42 is controlled to move up and down to achieve the up and down pressing and fixing of the wire. The transmission module includes a helical gear 6 52 mounted on a column shaft 28. The helical gear 6 52 is coaxially mounted with the column shaft 28, meaning that the rotation of the column shaft 28 drives the helical gear 6 52 to rotate. A helical gear 51 meshes with one side of the top of the helical gear 6 52. A helical gear 40 is connected to the top center of the helical gear 51 via a connecting shaft 48. Helical gears 3 49 are symmetrically meshed on both sides of the top of the helical gear 40. A helical gear 2 47 is connected to the middle side of the helical gear 3 49 via a connecting shaft 48. A helical gear 1 46 meshes with one side of the helical gear 2 47. The top of the helical gear 1 46 is fixedly connected to the bottom of the connecting rod 44. Because the rotation of the helical gear 40 drives the two helical gears 3 49 to rotate in opposite directions, the connection of the connecting shaft 48... The lower control helical gear 47 drives the helical gear 46 to rotate, that is, the rotation directions of the two helical gears 46 are opposite. At this time, in order to keep the pressure plates 42 connected to the connecting block 41 on both sides able to move in the same direction, the tooth groove direction of the lead screws 43 on both sides can be set to opposite angles. That is, there are two lead screws 43 on each side of the helical gear 40, and the upper and lower lead screws 43 mentioned above. The tooth groove direction of the two lead screws 43 on the upper side is opposite, and the tooth groove direction of the two lead screws 43 on the lower side is also opposite. Then, the transmission structure of the nut and the lead screw 43 is adjusted to keep the lifting components on both sides giving the pressure plate 42 the same power direction. In a preferred embodiment of the present invention, the side of the pressure plates 42 that contacts the wire is provided with evenly distributed protrusions 45. The protrusions 45 are made of rubber. When the control screw 4343 moves relative to each other to clamp the wire, the elastic pressure of the protrusions 45 is used to increase the clamping force on the wire. At the same time, the angle of the protrusions 45 is set to be inclined towards the inner end of the wire connection channel 20, that is, to increase the resistance to the outward pulling force of the wire connection channel 20 and improve the anti-pull strength. It should be noted that the support and positioning of the various structures in the transmission module and lifting assembly are mostly fixed by the support sleeve 53. That is, the end of the support sleeve 53 is fitted onto the connecting shaft 48 and other structures, and the other end is fixed in the inner wall of the upper column plate 10 or the lower column plate 11, thereby maintaining the meshing between the various structures and realizing the transmission and other functions.

[0030] The above embodiments of the present invention provide an electric welding terminal block. In use, the wire to be connected is placed in the wire connection channel 20, and its end extends to the inside of the wire positioning groove 23. One end is connected to the stud 35, and by rotating the stud 35, it is positioned inside the end of the internal threaded cylinder 36. The wire end is fixed by the threaded movement of the stud 35 and the internal threaded cylinder 36. Then, depending on the tightness of the connection, the rotating handle 24 inside the rotating handle groove 25 drives the rotating rod 26 to rotate. Under the connection of the column shaft 28, the screw 31 is controlled to move laterally along the internal thread of the internal threaded plate 32, thereby driving the clamping plate 34 to engage with the end of the stud 35, clamping and fixing the wire to the stud 35. At the same time, the column shaft 28 rotates. At that time, under the connection of helical gear six 52, in conjunction with helical gear five 51, helical gear four 50, helical gear three 49, connecting shaft 48, helical gear two 47, and helical gear one 46, the screw 43 is driven to rotate, and then the nut drives the connecting blocks 41 on both sides of the pressure plate 42 to move up and down. Then the pressure plate 42 is driven to press the wire placed inside the wire connection channel 20 to increase its anti-pull ability. Then the wire is stably connected to the electrical connection post kit 17 and electrical connection post plug 18, which is controllable. Then, in subsequent electric welding, the connection and separation of the upper column plate 10 and the lower column plate 11 are controlled manually, and the electrical connector tube 39 and the electrical connector 40 are locked in time to realize the connection and separation of the entire circuit, that is, to increase the convenience of electric welding operation.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
