Description

Technical Field

[0002] Circular connectors are devices that establish stable circuit connections between different electronic devices or cables. They are generally used in industrial gateways, industrial Internet gateways, and industrial intelligent gateways.

The two cables 3 are movably sleeved inside the two sealing rings 116, and each locking ring 117 is provided. The rings 117 are movably connected to each sealing ring 116 respectively, and a nut 118 is installed at the opposite ends of the two connecting caps 101. Each nut 118, the corresponding locking ring 117 and the corresponding sealing ring 116 are used to fix the corresponding cable 3 on the corresponding connecting cap 101. The connector mechanism 1 is provided with an anti-twist mechanism 2, and the anti-twist mechanism 2 includes two groups of side opening rings 201, two groups of slide grooves 209, two card slots 215 and two support rods 216. An iron ring 202 is fixed between each group of side opening rings 201, and a perforated slider 203 is slidably connected between each group of side opening rings 201. An arc-shaped electromagnet 204 is provided inside each perforated slider 203.

[0040] In this embodiment, when a circular connector is needed, the two arc-shaped electromagnets 204 are first connected to the controller of the equipment that needs to use the circular connector (such as a robot in an automated production line such as automobile manufacturing and electronic equipment production), and then one of the nuts 118 is put on one end of one of the cables 3, and then the sealing ring 116 with a locking ring 117 is also put on one end of one of the cables 3, and then the multiple wires at one end of the cable 3 are respectively connected to each female pin 114 installed on the female socket 102, and then the sealing ring 116 with the locking ring 117 is moved to the inside of the corresponding connecting cap 101, and then the nut 118 is threadedly connected to the corresponding connecting cap 101, and then the connecting cap 101 and the corresponding locking ring 117 can be used. The tightening ring 117, the corresponding sealing ring 116 and the corresponding nut 118 cooperate to firmly fix the cable 3 on the corresponding connecting cap 101. Finally, repeat the above steps to connect the multiple wires at one end of the other cable 3 to each male pin 115 on the male socket 103, and fix them on the corresponding connecting cap 101. At the same time, connect the other ends of the two cables 3 to the corresponding equipment components. When one end of the two cables 3 is fixed, the two nuts 118 are fixed by the anti-twist mechanism 2. When the two nuts 118 are fixed by the anti-twist mechanism 2, the two connecting caps 101 are moved toward each other. At this time, the two moving connecting caps 101 will respectively drive the male socket 103 with the male pin 115 and the female pin 115 connected to it. 14 of the female seat 102 moves, and the two connecting caps 101 that move at the same time will also drive the corresponding sealing ring 116, the corresponding locking ring 117, the corresponding nut 118, one end of the corresponding cable 3 and the corresponding part of the anti-twist mechanism 2 to move at the same time. At the same time, the moving male seat 103 will also drive all the card blocks 108 and the sealing ring 104 thereon to move, and the moving female seat 102 will also drive all the spring bodies 113, all the L-shaped rods 111 and all the limit rods 112 to move. When the female seat 102 and the male seat 103 are about to dock, the positioning groove 105 and the positioning block 106 are used to adjust the docking angle of the female seat 102 and the male seat 103, and then the male seat 103 is docked with the female seat 102, and then at the same time Move all the L-shaped rods 111. At this time, each L-shaped rod 111 that moves will drive the limit rod 112 connected to it to move into the cylindrical groove 110. At the same time, moving each L-shaped rod 111 will also cause the corresponding spring body 113 to be compressed under the cooperation of the corresponding mounting groove 109.

At the same time, each male pin 115 is also just docked with the corresponding female pin 114.Then, the force applied to all L-shaped rods 111 is released. At this time, each L-shaped rod 111 will return to its original position under the cooperation of the corresponding cylindrical groove 110, the corresponding mounting groove 109, and the corresponding spring body 113. When all L-shaped rods 111 are returned to their original position, the clamping end of each L-shaped rod 111 passes through the corresponding clamping block 108. At this time, under the action of all L-shaped rods 111, each clamping block 108 will be tightly clamped inside the corresponding clamping hole 107. At this time, even if the connected circular connector is subjected to vibration, impact, etc., the female socket 102 and the male socket 103 will not loosen, and the male socket 103 will not fall off from the female socket 102, thereby ensuring the stability of the connection between the devices.

Each arc-shaped electromagnet 204, the corresponding iron ring 202 and the corresponding group of side opening rings 201 are used to control whether the corresponding perforated slider 203 can slide. The inner wall of the opening at one end of each support rod 216 is preset with two symmetrical mounting holes 211, and each mounting hole The interior of 211 is provided with a T-shaped pull rod 213 and a return spring 212, and the interior of each set of slide grooves 209 is provided with an auxiliary rod 210. A clamping rod 214 is fixed to the bottom of each auxiliary rod 210 near one end. Each T-shaped pull rod 213 is used to control whether the corresponding auxiliary rod 210 can move. Each support rod 216 is used to adjust the distance between the corresponding clamping rod 214 and the corresponding perforated slider 203. The outer wall of each iron ring 202 is in contact with the magnetic end surface of each arc-shaped electromagnet 204 respectively. The through holes of the two perforated sliders 203 are provided with connecting blocks 205. The bottoms of the two connecting blocks 205 are fixed to the tops of the two arc-shaped electromagnets 204 respectively. The bottoms of the two support rods 216 are preset with rectangular grooves 2 06, the top of the inner wall of the two rectangular grooves 206 is preset with a T-shaped hole 207, the top of the two connecting blocks 205 is respectively slidably connected to the inside of the two rectangular grooves 206, the inside of the two T-shaped holes 207 is slidably connected with a rectangular block 208, and the two rectangular blocks 208 are respectively installed on the top of the two connecting blocks 205, and each set of slide grooves 209 is respectively preset on both sides of the inner wall of one end opening of each support rod 216, one end of each return spring 212 is respectively fixed to the inner wall of each mounting hole 211, and the other end of each return spring 212 is respectively fixed to the surface of each T-shaped pull rod 213, and one end of each return spring 212 is respectively movably sleeved on one end of each T-shaped pull rod 213, and one end of each T-shaped pull rod 213 is respectively It is slidably embedded in the surface of the corresponding auxiliary rod 210, and the bottom end of each clamping rod 214 is movably clamped in the inside of each clamping slot 215. One end of each support rod 216 is movably penetrated through the surface of each perforated slider 203 and the inner wall of the through hole of each perforated slider 203 in turn. A group of hand-tightening bolts 217 are threaded through the top of each perforated slider 203, and the threaded end of each group of hand-tightening bolts 217 is respectively against the top of the corresponding support rod 216. The connector mechanism 1 includes two connecting caps 101, and the opposite ends of the two connecting caps 101 are respectively equipped with nuts 118. Each group of side opening rings 201 and each iron ring 202 are respectively fixed on each connecting cap 101, and the two clamping slots 215 are respectively preset on the outer walls of the two nuts 118.

[0042] In this embodiment, when one end of the two cables 3 is fixed, one of the perforated sliders 203 is first moved between the corresponding set of side opening rings 201. At this time, the moving perforated slider 203 will drive the corresponding arc-shaped electromagnet 204, a set of hand-tightening bolts 217, the corresponding connecting block 205, the corresponding rectangular block 208, the corresponding two T-shaped pull rods 213, the corresponding two return springs 212, the corresponding auxiliary rod 210 and the corresponding clamping rod 214 to move simultaneously. When the bottom end center of the movable clamping rod 214 moves to the straight line corresponding to the center of the clamping groove 215, the control device on the above device is used. The arc electromagnet 204 is started by the device, and the arc electromagnet 204 is energized. At this time, the energized arc electromagnet 204 will be tightly fixed on the iron ring 202, that is, the clamping rod 214 can no longer rotate around the corresponding connecting cap 101, and then the corresponding set of hand-tightening bolts 217 are loosened, and then the corresponding support rod 216 is moved. At this time, the moving support rod 216 will drive the clamping rod 214 to move with the cooperation of the auxiliary rod 210. When the clamping rod 214 moves to the top of the corresponding card slot 215, the support rod 216 is stopped from moving, and then all the loosened hand-tightening bolts 217 are tightened, and then the corresponding support rod 216 is tightened. One end of the two T-shaped pull rods 213 on the support rod 216 is moved away from the corresponding auxiliary rod 210. At this time, each T-shaped pull rod 213 that moves will cooperate with the corresponding mounting hole 211, so that the corresponding return spring 212 is stretched, and then the auxiliary rod 210 is moved inside the corresponding set of slide grooves 209. Then the auxiliary rod 210 drives the clamping rod 214 to move. When the bottom end of the clamping rod 214 moves to the inside of the clamping groove 215 and cannot move, the force applied to each T-shaped pull rod 213 is released, so that each T-shaped pull rod 213 cooperates with the rebound force of the corresponding return spring 212 When the two T-shaped pull rods 213 are reset to their original positions, the corresponding auxiliary rod 210 is fixed, that is, the card rod 214 can no longer move. Then repeat the above steps, move the bottom end of the other card rod 214 to the inside of the corresponding card slot 215, and fix the corresponding auxiliary rod 210. When the two nuts 118 are fixed by the anti-twist mechanism 2, under the action of the anti-twist mechanism 2, the connection between the cable 3 and the circular connector will not loosen due to the torsional force generated by the cable 3 when the robot moves, thereby ensuring the normal operation of the equipment and data transmission.

[0043] The effect and working principle of the entire mechanism are as follows:

[0044] In the preparation stage, first connect the two arc-shaped electromagnets 204 to the controller of the equipment that needs to use the circular connector (such as the robot in the automated production line of automobile manufacturing, electronic equipment production, etc.), then put one of the nuts 118 on one end of one of the cables 3, and then put the sealing ring 116 with the locking ring 117 on one end of one of the cables 3, and then connect the multiple wires at one end of the cable 3 to each female pin 114 installed on the female socket 102, and then move the sealing ring 116 with the locking ring 117 to the female socket 102. The corresponding connection cap 101 is then threaded onto the nut 118. The connection cap 101, the corresponding locking ring 117, the corresponding sealing ring 116, and the corresponding nut 118 can be used to tightly secure the cable 3 to the corresponding connection cap 101. Repeat the above steps to connect the multiple wires at one end of the other cable 3 to each male pin 115 on the male socket 103, and secure them to the corresponding connection cap 101. At the same time, connect the other ends of the two cables 3 to the corresponding equipment components.

[0045] During the anti-twist installation phase, when one end of the two cables 3 is fixed, one of the hole sliders 203 is first moved between the corresponding set of side opening rings 201. At this time, the moving hole slider 203 will drive the corresponding arc-shaped electromagnet 204, a set of hand-tightening bolts 217, the corresponding connecting block 205, the corresponding rectangular block 208, the corresponding two T-shaped pull rods 213, the corresponding two return springs 212, the corresponding auxiliary rod 210 and the corresponding clamping rod 214 to move simultaneously. When the bottom end center of the movable clamping rod 214 moves to the corresponding When the arc electromagnet 204 is on the straight line with the center of the card slot 215, the controller on the above device is used to start the arc electromagnet 204 and energize the arc electromagnet 204. At this time, the energized arc electromagnet 204 will be tightly fixed on the iron ring 202, that is, the card rod 214 can no longer rotate around the corresponding connecting cap 101. Then, the corresponding set of hand-tightening bolts 217 are loosened, and then the corresponding support rod 216 is moved. At this time, the moving support rod 216 will drive the card rod 214 to move with the cooperation of the auxiliary rod 210. When the card rod 214 moves to the corresponding card slot 215, stop the support rod 216 from moving, then tighten all the loosened hand bolts 217, and then remove one end of the two T-shaped pull rods 213 on the corresponding support rod 216 from the corresponding auxiliary rod 210. At this time, each T-shaped pull rod 213 that moves will cooperate with the corresponding mounting hole 211, so that the corresponding return spring 212 is stretched, and then the auxiliary rod 210 is moved inside the corresponding set of slide grooves 209. Then the auxiliary rod 210 will drive the card rod 214 to move. When the card rod 2 When the bottom end of the two T-shaped rods 213 moves into the slot 215 and cannot move, release the force applied to each T-shaped rod 213, allowing each T-shaped rod 213 to return to its original position under the cooperation of the rebound force of the corresponding return spring 212. When both T-shaped rods 213 return to their original positions, the corresponding auxiliary rod 210 is fixed, that is, the rod 214 cannot move any further. Then repeat the above steps to move the bottom end of the other rod 214 into the corresponding slot 215 and fix the corresponding auxiliary rod 210.

[0046] During the docking phase, when the two nuts 118 are fixed by the anti-twist mechanism 2, the two connecting caps 101 are moved toward each other. At this time, the two moving connecting caps 101 will respectively drive the male base 103 with the male pin 115 and the female base 102 with the female pin 114 connected thereto to move. At the same time, the two moving connecting caps 101 will also respectively drive the corresponding sealing ring 116, the corresponding locking ring 117, the corresponding nut 118, one end of the corresponding cable 3 and the corresponding part of the anti-twist mechanism 2 to move at the same time. At the same time, the moving male base 103 will also drive all the blocks 108 and the sealing ring 104 thereon to move, and the moving female base 102 will also drive all the spring bodies 113. All L-shaped rods 111 and all limiting rods 112 move. When the female seat 102 and the male seat 103 are about to dock, the docking angle of the female seat 102 and the male seat 103 is adjusted by using the cooperation of the positioning groove 105 and the positioning block 106. Then the male seat 103 is docked with the female seat 102. Then all L-shaped rods 111 are moved at the same time. At this time, each L-shaped rod 111 that moves will drive the limiting rod 112 connected to it to move inside the cylindrical groove 110. At the same time, each L-shaped rod 111 that moves will also cooperate with the corresponding mounting groove 109 to compress the corresponding spring body 113. When the clamping ends of all L-shaped rods 111 are respectively moved from the corresponding When the inside of the card hole 107 is moved out, the female seat 102 and the male seat 103 are docked. When the female seat 102 and the male seat 103 are docked, each card block 108 is just clamped in the inside of each card hole 107, and the sealing ring 104 is also squeezed and deformed, and is located between the female seat 102 and the male seat 103. At the same time, each male pin 115 is just docked with the corresponding female pin 114. Then loosen the force applied to all L-shaped rods 111. At this time, each L-shaped rod 111 will return to its original position under the cooperation of the corresponding cylindrical groove 110, the corresponding mounting groove 109 and the corresponding spring body 113. When all L-shaped rods 111 are reset to their original position When the connector 102 is in the right position, the clamping end of each L-shaped rod 111 passes through the corresponding clamping block 108. At this time, under the action of all L-shaped rods 111, each clamping block 108 will be tightly clamped in the corresponding clamping hole 107. At this time, even if the docked circular connector is subjected to vibration, impact, etc., the female base 102 and the male base 103 will not loosen, and the male base 103 will not fall off from the female base 102, thereby ensuring the stability of the connection between the devices. At the same time, under the action of the anti-twisting mechanism 2, the connection between the cable 3 and the circular connector will not loosen due to the torsional force generated by the cable 3 when the robot moves, thereby ensuring the normal operation of the equipment and data transmission.
