Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, in particular to an insulating heat shrink terminal and a connection structure thereof. Background Art

[0002] Insulation heat shrink terminal assembly equipment is an automated device specifically used to connect insulation heat shrink tubing to the ends of wires or cables. This equipment is usually used in electrical engineering and industrial manufacturing to ensure that the connection of the wires or cables has good insulation performance and mechanical strength, while being able to withstand high temperatures and harsh environments.

[0003] In the prior art, the terminals and wires after crimping are transported to a specified location by a clamp. At this time, the long heat shrink tube transmitted through the feed port will be cut into heat shrink tubes of specified lengths by a cutting knife. At the same time, the part where the terminal and the wire are connected is sent into the heat shrink tube by the clamp and fine-tuned to ensure that the heat shrink tube completely covers the terminal and the connection part between the terminal and the wire and leaves a certain overlapping part, so as to form a tight seal when heated and shrunk.

[0004] There are still some problems in the actual application of the above scheme. Although the existing device can cover the heat shrink tube on the terminal and the connection between the terminal and the wire, due to the previous process of crimping one end of the wire and the terminal connection, burrs will appear on the terminal surface due to irregular operation. These sharp burrs will scratch the heat shrink sleeve when the heat shrink sleeve is heated and shrunk and tightly fits on the terminal surface, which will cause a gap between the heat shrink sleeve and the terminal and reduce the sealing effect of the heat shrink sleeve, making it easier for moisture, dust or other contaminants to enter, which will affect the electrical performance and reliability of the entire connection system. Secondly, since the added adaptive grinding mechanism cannot be reset during operation, the continuity of the insulating heat shrink terminal assembly equipment will be reduced, which will affect the work efficiency of the enterprise.

[0005] To this end, the present invention provides an insulating heat shrinkable terminal and a connection structure thereof. Summary of the invention

[0011] Preferably, a guide plate is provided on the outer ring surface of the reciprocating rod, and a guide opening is symmetrically opened on the top of the guide plate. The reciprocating rod is slidably connected in the guide opening opened on the top of the guide plate, and a wiping ring is fixedly connected to the end of the reciprocating rod away from the guide block, and the side surface of the wiping ring is a wave structure.

[0012] Preferably, the adaptive grinding mechanism includes a second base, the second base is fixedly connected to the first base, a rotating sleeve is rotatably connected inside the second base, and the outer annular surface of the rotating sleeve is transmission-connected to a transmission belt.

[0013] Preferably, an inner cavity is provided inside the rotating sleeve, a guide ring is fixedly connected to the side wall of the inner cavity of the rotating sleeve, a plurality of groups of first guide grooves are provided on one side of the guide ring, and reciprocating grinding blocks are slidably connected inside the first guide grooves.

[0017] An insulating heat shrink terminal comprises a terminal material. The outer ring surface of the terminal material is covered with a heat shrink sleeve, and a wire is inserted into the terminal material.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention starts a first driving source to drive the rotating shaft to rotate, and at the same time, when the rotating shaft rotates, it will drive the first rotating column to rotate synchronously. Since an annular guide block is fixed on the outer ring surface of the first rotating column, and the reciprocating rod slides on the outer surface of the guide block, when the first rotating column rotates with the guide block, the two groups of reciprocating rods perform alternating reciprocating linear motion along the two groups of guide openings symmetrically opened on the top of the guide plate. At the same time, two groups of wiping rings are fixed on the reciprocating rod away from the guide block, and the opposite sides of the two groups of wiping rings are arranged in a wave structure. At this time, the dirt on the surface of the terminal material can be cleaned off by the alternating motion of the two groups of wiping rings, thereby reducing unnecessary scratches and damages on the surface of the terminal during the polishing process, and protecting the integrity of the surface of the terminal material. Secondly, since the opposite sides of the two groups of wiping rings are arranged in a wave structure, the dirt attached to the inner ring of the wiping ring after wiping can be cleaned off by vibration during the movement, thereby improving the subsequent cleaning quality.

[0020] 2. The present invention can deliver the terminal material to the middle of multiple groups of reciprocating polishing blocks through the cooperation of the electric telescopic rod and the second clamp. At this time, due to the push of the external force, the multiple groups of reciprocating polishing blocks will move upward along the first guide groove opened on the side of the guide ring. At this time, the transmission of the transmission belt can drive all the devices in the adaptive polishing mechanism to rotate. During the rotation, due to the pulling force of the reset spring, the reciprocating polishing block will stick to the surface of the terminal material, and then the surface of the terminal material can be polished, so that the surface of the terminal material is smoother, which helps the heat shrink sleeve to better fit the surface of the terminal material after heating and shrinking, thereby improving the overall sealing performance. At the same time, because the reciprocating polishing block can adjust the moving distance of the reciprocating polishing block according to the diameter of the terminal material, the adaptive polishing mechanism can comprehensively polish the surface of the terminal material, thereby improving the polishing effect.

[0021] 3. The present invention is that when the sliding block moves to the intersection of the vertical groove and the arc groove at the bottom of the third guide groove, and after the grinding work is completed, the second clamp will clamp the wire, and the second driving source will be started and drive the third guide groove to rotate counterclockwise. At this time, the telescopic sleeve will continue to lift the reciprocating grinding block through the linkage rod. At this time, the first clamp will be loosened and the heat shrink sleeve cut by the cutting knife will be put on the outer surface of the terminal material, and the terminal material, heat shrink sleeve and wire will be sent to the next process through the cooperation of the electric telescopic rod and the second clamp. When the second driving source rotates 360 degrees counterclockwise, the sliding block will move to the top of the third guide groove and return to the bottom through the vertical groove of the third guide groove. At this time, the reset spring is in an unstressed state. When the reset spring is in an unstressed state, the reciprocating grinding block will complete the reset, thereby improving the continuity of the insulating heat shrink terminal assembly equipment during operation, and then improving the work efficiency of the enterprise.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0038] like Figures 1 to 10 As shown, one embodiment of the present invention is:

[0039] A connection structure of an insulating heat shrink terminal, comprising a housing device 2, the housing device 2 comprising a workbench 201, a first base 202 is fixedly connected to the top of the workbench 201, a cutting knife 203 is slidably connected to the upper part of the first base 202, a first clamping hand 204 is slidably connected to the top of the first base 202, an electric telescopic rod 205 is slidably connected to the side wall of the workbench 201, a second clamping hand 206 is fixedly connected to the end of the electric telescopic rod 205 away from the workbench 201, a feed port 207 is opened through the middle of the first base 202, and an adaptive grinding mechanism 4 is arranged on the upper part of the housing device 2;

[0040] The adaptive grinding mechanism 4 is used to grind the surface of the material.

[0041] Specifically, although the existing device can cover the terminal material 101 and the connection between the terminal material 101 and the wire 103 with the heat shrink tube, burrs may appear on the surface of the terminal material 101 due to improper operation when crimping one end of the wire 103 and the connection between the terminal material 101 in the previous process. These sharp burrs may scratch the heat shrink sleeve 102 when the heat shrink sleeve 102 is heated and shrunk and tightly attached to the surface of the terminal material 101, thereby causing a gap between the heat shrink sleeve 102 and the terminal material 101, and reducing the sealing effect of the heat shrink sleeve 102, making it easier for moisture, dust or other contaminants to enter, thereby affecting the electrical performance and reliability of the entire connection system.

[0042] Therefore, the present invention solves this problem by setting a certain structure. When the terminal material 101 and the wire 103 are crimped, the second clamp 206 will move along the guide groove of the side wall of the workbench 201 and clamp the terminal material 101 and the wire 103 after crimping. At this time, the second clamp 206 will move through the guide groove of the side wall of the workbench 201 and bring the crimped terminal material 101 and the wire 103 to the front of the shell device 2. At this time, the heat shrinkable long tube will enter the feed port 207 and be clamped by the first clamp 204. At this time, the heat shrinkable long tube will be cut to a suitable length by the opposite movement of the two sets of cutting knives 203. When the two sets of cutting knives 203 complete the cutting, the first clamp 204 will clamp the heat shrinkable long tube. One clamp 204 will move toward the direction of the second clamp 206. Since the second clamp 206 and the first clamp 204 are parallel on the same vertical plane, the heat shrink sleeve 102 can be put on the outer surface of the terminal material 101 through the movement of the first clamp 204. However, since the terminal material 101 will have burrs during the crimping process, and the burrs will scratch the heated heat shrink sleeve 102 when the heat shrink sleeve 102 is heated, shrunk and tightly fitted to the surface of the terminal material 101, the surface of the terminal material 101 after crimping can be polished by rotating the adaptive polishing mechanism 4, so that the heat shrink sleeve 102 can better fit the surface of the terminal material 101 after heating and shrinking, thereby improving the overall sealing performance. Embodiment 2

[0043] like Figure 4 As shown, in this embodiment, a rotating wiping mechanism 3 for pre-cleaning is arranged on the top of the shell device 2, and the rotating wiping mechanism 3 includes a first driving source 301, the output shaft of the first driving source 301 is fixedly connected to a rotating shaft 302, the outer annular surface of the rotating shaft 302 is transmission-connected to a transmission belt 303, and the end of the rotating shaft 302 away from the first driving source 301 is fixedly connected to a first rotating column 304.

[0044] Specifically, when the second clamp 206 brings the crimped terminal material 101 to the front of the rotating wiping mechanism 3, the motor is started. At this time, the output shaft of the motor will drive the first rotating column 304 to rotate synchronously. At the same time, when the rotating shaft 302 rotates, it will be transmitted through the transmission belt 303 and provide power for subsequent devices.

[0045] like Figure 4 As shown, in this embodiment, the outer ring surface of the first rotating column 304 is fixedly connected with a guide block 305, the guide block 305 is an annular structure, and the outer ring surface of the guide block 305 is slidably connected with a reciprocating rod 306.

[0046] Specifically, when the first rotating column 304 rotates, it will drive the guide block 305 on its outer ring surface to rotate. Since the guide block 305 is an annular slider and the top and bottom ends of the guide block 305 are not on the same horizontal plane, when the guide block 305 rotates, the reciprocating rod 306 sliding on its surface will form an alternating motion.

[0047] like Figure 4 As shown, in this embodiment, a guide plate 307 is provided on the outer ring surface of the reciprocating rod 306, and a guide opening is symmetrically opened on the top of the guide plate 307. The reciprocating rod 306 is slidably connected in the guide opening opened on the top of the guide plate 307, and a wiping ring 308 is fixedly connected to the end of the reciprocating rod 306 away from the guide block 305, and the side of the wiping ring 308 is a wave structure.

[0048] Specifically, the rotation of the first rotating column 304 and the guide block 305 can enable the two groups of reciprocating rods 306 to complete alternating motion. At this time, the two groups of reciprocating rods 306 are limited by the guide openings symmetrically opened on the top of the guide plate 307, so that the two groups of reciprocating rods 306 can perform alternating reciprocating linear motion, and at the same time, the wiping ring 308 will be driven to perform alternating reciprocating linear motion, so that the dirt on the surface of the terminal material 101 can be cleaned, thereby reducing unnecessary scratches and damages on the surface of the terminal material 101 during the polishing process, and protecting the integrity of the surface of the terminal material 101. Moreover, since the opposite sides of the two groups of wiping rings 308 are arranged as wave structures, the dirt attached to the inner ring of the wiping ring 308 after wiping can be cleaned off by vibration during the movement, thereby improving the subsequent cleaning quality.

[0049] like Figure 5 As shown, the adaptive grinding mechanism 4 of this embodiment includes a second base 401, which is fixedly connected to the first base 202, and a fixed sleeve 402 is rotatably connected inside the second base 401.

[0050] Specifically, the second base 401 provides support for the fixing sleeve 402 without affecting the rotation of the fixing sleeve 402 .

[0051] like Figure 6 As shown, in this embodiment, an inner cavity is opened inside the fixed sleeve 402, and a guide ring 403 is fixedly connected to the side wall of the inner cavity of the fixed sleeve 402. A plurality of first guide grooves 404 are opened on one side of the guide ring 403, and a reciprocating grinding block 405 is slidably connected inside the first guide grooves 404.

[0052] Specifically, when the second clamp 206 delivers the cleaned terminal material 101 to the middle of the fixed sleeve 402, the electric telescopic rod 205 will start, and at the same time, the end of the terminal material 101 with a smaller diameter will be delivered between the multiple groups of reciprocating polishing blocks 405. Since the multiple groups of reciprocating polishing blocks 405 still retain a certain gap in the middle in the initial state, when the electric telescopic rod 205 moves, the multiple groups of reciprocating polishing blocks 405 will be squeezed through the terminal material 101, and the multiple groups of reciprocating polishing blocks 405 will move along the guidance of the first guide groove 404. At this time, the multiple groups of reciprocating polishing blocks 405 always keep in contact with the outer ring surface of the terminal material 101.

[0053] like Figure 6 and Figure 7 As shown, in this embodiment, a sliding column 406 is fixedly connected to the top of the side wall of the reciprocating grinding block 405, and multiple groups of second guide grooves 407 are opened on the side of the fixed sleeve 402. The sliding columns 406 all slide inside the second guide grooves 407, and the outer ring surface of the fixed sleeve 402 is transmission-connected to the transmission belt 303.

[0054] Specifically, when the terminal material 101 enters between multiple groups of reciprocating grinding blocks 405, the next group of terminal material 101 will move to the rotating wiping mechanism 3. At this time, the rotating wiping mechanism 3 will start, and at the same time, the transmission belt 303 will be used to drive all the mechanisms of the adaptive grinding mechanism 4 except the second base 401 to rotate. At this time, the grinding of the smaller diameter end of the terminal material 101 will be completed.

[0055] like Figure 8 and Fig. 9 As shown, in this embodiment, the top of the reciprocating grinding block 405 away from the sliding column 406 is fixedly connected to a linkage rod 408, the middle of the linkage rod 408 is fixedly connected to a reset spring 409, the end of the reset spring 409 away from the linkage rod 408 is fixedly connected to the guide ring 403, the end of the linkage rod 408 away from the reciprocating grinding block 405 is fixedly connected to a telescopic sleeve 410, and the side wall inside the telescopic sleeve 410 is fixedly connected to a sliding block 411.

[0056] Specifically, when the smaller diameter end of the terminal material 101 is polished, the rotating wiping mechanism 3 will stop working and the terminal material 101 will continue to move toward the first clamping hand 204. At this time, the first clamping hand 204 will clamp the smaller end of the terminal material 101, and the multiple groups of reciprocating polishing blocks 405 will continue to move outward, and will drive the linkage rod 408 to move synchronously during the movement. Since the linkage rod 408 is pulled by the reset spring 409, the polishing end of the reciprocating polishing block 405 will still fit the outer ring surface of the terminal material 101. Since the movement of the reciprocating polishing block 405 will synchronously drive the telescopic sleeve 410 through the linkage rod 408 Move, at this time, the sliding block 411 inside the telescopic sleeve 410 will move from the middle of the vertical groove at the bottom of the third guide groove 414 to the intersection of the vertical groove and the arc groove, and the rotating wiping mechanism 3 will continue to work, and at the same time drive all mechanisms except the second base 401 in the adaptive grinding mechanism 4 to rotate, and complete the grinding of the outer ring surface of the larger diameter end of the terminal material 101 through multiple groups of reciprocating grinding blocks 405, and the surface of the terminal material 101 after the grinding work is completed is smoother, which helps the heat shrink sleeve 102 to better fit the surface of the terminal material 101 after heating and shrinking, thereby improving the overall sealing performance.

[0057] like Fig.10 As shown, in this embodiment, a second driving source 412 is fixedly provided on the outer ring surface of the guide ring 403, and a second rotating column 413 is fixedly connected to the output end of the second driving source 412. A third guide groove 414 is opened on the outer ring surface of the second rotating column 413, and the sliding block 411 slides in the third guide groove 414.

[0058] Specifically, when the sliding block 411 moves to the intersection of the vertical groove and the arc groove at the bottom of the third guide groove 414, and the grinding work is completed, the second clamping hand 206 will clamp the wire 103, and at the same time the second driving source 412 will start and drive the third guide groove 414 to rotate counterclockwise. At this time, the telescopic sleeve 410 will continue to lift the reciprocating grinding block 405 through the linkage rod 408. At this time, the first clamping hand 204 will be loosened and the heat shrink sleeve 102 cut by the cutting knife 203 will be put on the outer surface of the terminal material 101, and the electric telescopic rod 205 will be used to move the heat shrink sleeve 102 to the outer surface of the terminal material 101. The terminal material 101, the heat shrink sleeve 102 and the wire 103 are sent to the next process in cooperation with the second clamp 206. When the second driving source 412 rotates 360 degrees counterclockwise, the sliding block 411 moves to the top of the third guide groove 414 and returns to the bottom through the vertical groove of the third guide groove 414. At this time, the reset spring 409 is in an unstressed state. When the reset spring 409 is in an unstressed state, the reciprocating grinding block 405 completes the reset, thereby improving the continuity of the insulating heat shrink terminal assembly equipment during operation, and further improving the work efficiency of the enterprise.

[0059] like Figure 1As shown, the present embodiment is an insulated heat shrinkable terminal, comprising a terminal material 101 , a heat shrink sleeve 102 is sleeved on the outer annular surface of the terminal material 101 , and a wire 103 is inserted into the terminal material 101 .

[0060] Working principle: when the second clamp 206 brings the terminal material 101 after crimping to the front of the rotating wiping mechanism 3, the motor is started. At this time, the output shaft of the motor will drive the first rotating column 304 to rotate synchronously. At the same time, when the rotating shaft 302 rotates, it will be transmitted through the transmission belt 303 and provide power for subsequent devices.

[0061] When the first rotating column 304 rotates, it will drive the guide block 305 on its outer ring surface to rotate. Since the guide block 305 is an annular slider and the top and bottom ends of the guide block 305 are not on the same horizontal plane, the reciprocating rod 306 sliding on its surface will form an alternating motion when the guide block 305 rotates.

[0062] Since the rotation of the first rotating column 304 and the guide block 305 can enable the two groups of reciprocating rods 306 to complete alternating motion, the two groups of reciprocating rods 306 are limited by the guide openings symmetrically opened on the top of the guide plate 307, so that the two groups of reciprocating rods 306 can perform alternating reciprocating linear motion, and at the same time drive the wiping ring 308 to perform alternating reciprocating linear motion, so that the dirt on the surface of the terminal material 101 can be cleaned, thereby reducing unnecessary scratches and damages on the surface of the terminal material 101 during the polishing process, and protecting the integrity of the surface of the terminal material 101. Moreover, since the opposite sides of the two groups of wiping rings 308 are arranged as wave structures, the dirt attached to the inner ring of the wiping ring 308 after wiping can be cleaned off by vibration during the movement, thereby improving the subsequent cleaning quality.

[0063] The second base 401 provides support for the fixing sleeve 402 while not affecting the rotation of the fixing sleeve 402 .

[0064] When the second clamp 206 delivers the cleaned terminal material 101 to the middle of the fixed sleeve 402, the electric telescopic rod 205 will start and simultaneously deliver the end with a smaller diameter of the terminal material 101 between the multiple groups of reciprocating polishing blocks 405. Since the multiple groups of reciprocating polishing blocks 405 still retain a certain gap in the middle in the initial state, when the electric telescopic rod 205 moves, the multiple groups of reciprocating polishing blocks 405 will be squeezed through the terminal material 101 and moved along the guidance of the first guide groove 404. At this time, the multiple groups of reciprocating polishing blocks 405 always keep in contact with the outer ring surface of the terminal material 101.

[0065] When the terminal material 101 enters between multiple groups of reciprocating grinding blocks 405, the next group of terminal material 101 will move to the rotating wiping mechanism 3. At this time, the rotating wiping mechanism 3 will be started, and at the same time, the transmission belt 303 will be used to drive all the mechanisms of the adaptive grinding mechanism 4 except the second base 401 to rotate. At this time, the grinding work on the smaller diameter end of the terminal material 101 will be completed.

[0066] When the smaller diameter end of the terminal material 101 is polished, the rotating wiping mechanism 3 will stop working and the terminal material 101 will continue to move toward the first clamp 204. At this time, the first clamp 204 will clamp the smaller end of the terminal material 101, and the multiple groups of reciprocating polishing blocks 405 will continue to move outward, and at the same time, they will drive the linkage rod 408 to move synchronously. Since the linkage rod 408 is pulled by the reset spring 409, the polishing end of the reciprocating polishing block 405 will still fit the outer ring surface of the terminal material 101. Since the movement of the reciprocating polishing block 405 will synchronously drive the telescopic sleeve 410 to move through the linkage rod 408 Move, at this time, the sliding block 411 inside the telescopic sleeve 410 will move from the middle of the vertical groove at the bottom of the third guide groove 414 to the intersection of the vertical groove and the arc groove, and the rotating wiping mechanism 3 will continue to work, and at the same time drive all mechanisms except the second base 401 in the adaptive grinding mechanism 4 to rotate, and complete the grinding of the outer ring surface of the larger diameter end of the terminal material 101 through multiple groups of reciprocating grinding blocks 405, and the surface of the terminal material 101 after the grinding work is completed is smoother, which helps the heat shrink sleeve 102 to better fit the surface of the terminal material 101 after heating and shrinking, thereby improving the overall sealing performance.

[0067] When the sliding block 411 moves to the intersection of the vertical groove and the arc groove at the bottom of the third guide groove 414, and the grinding work is completed, the second clamping hand 206 will clamp the wire 103, and the second driving source 412 will be started, and drive the third guide groove 414 to rotate counterclockwise. At this time, the telescopic sleeve 410 will continue to lift the reciprocating grinding block 405 through the linkage rod 408.
