Description
Technical Field
[0001] The utility model relates to the technical field of cable docking, in particular to a coaxial connector with an internal limiting structure. Background Art
[0002] Cable docking is a very important part of power engineering. The correct docking method can ensure the safe operation of the cable and avoid cable failures and accidents. Before docking, it is necessary to check whether the quality and specifications of the cable meet the requirements, and whether the insulation of the cable is intact. If the cable is found to have quality problems or insulation damage, it should be replaced in time. The most common way is to twist the connection. When connecting, the insulation layer of the cable needs to be stripped for a distance, and then the two cables to be connected are directly and tightly twisted together. Cross the core wire ends of the cable, and then wrap them around each other for 2 to 3 turns, and then straighten the wire ends. Each wire end should be tightly wrapped with another wire. After about 5 turns, remove the excess wire ends.
[0003] Coaxial connectors refer to the parts used to connect the ends of two shafts to ensure that the center lines of the two shafts are on the same axis. They are generally used to connect the driving shaft and the driven shaft to transmit the rotational motion of the driving shaft to the driven shaft. There are 1. General coaxial connectors; 2. Dual coaxial connectors 3. Triaxial connectors; 4. High-voltage coaxial connectors; 5. PCB coaxial connectors, and the coupling mechanisms are: 1. Threaded connection; 2. Double bayonet insertion type; 3. Sliding type and 4. Snap-on type.
[0004] In the process of realizing the present invention, the inventors found that the prior art had the following problems: 1. After the existing coaxial connector passes through the cable, it is often impossible to limit its position, so that the cable may fall off the connector; 2. The existing coaxial connector often has only a single fixing method for fixing the cable. After the two connectors are connected, the cable is not very stable and may still fall off. Utility Model Content
[0005] The purpose of the utility model is to provide a coaxial connector with an internal limiting structure to solve the problem that the existing coaxial connector mentioned in the above background technology is often unable to limit the position of the cable after it passes through, so that the cable may fall off from the connector, and the existing coaxial connector often has only a single fixing method for fixing the cable. After the two connectors are connected, the stability of the cable is not high and the cable may still fall off.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a coaxial connector with an internal limiting structure, comprising a first cable, the first cable vertically passing through the interior of the first connector, a plurality of elastic connectors fixedly connected to the bottom of the first connector, the bottom ends of the elastic connectors are plugged into the interior of a limiting device, the bottom of the limiting device is fixedly connected to the top of a second connector, a pulley limiting group is fixedly connected to the inner wall of the second connector, and a second cable vertically passes through the interior of the second connector.
[0007] Further preferably, the limiting device consists of a top plate, a bottom plate, a stop block, a spring and a limiting rod, wherein a plurality of strip grooves are provided at the bottom of the top plate, and a plurality of limiting grooves are provided at the top of the bottom plate, and the stop block and the limiting rod are fixedly connected as a whole by a spring, and the stop block and the limiting rod are slidably connected to the inside of the limiting groove by an integral whole formed by the spring, and the bottom of the top plate is fixedly connected to the top of the bottom plate.
[0008] Further preferably, the number of the elastic connecting members is the same as the number of the strip grooves and the limiting grooves.
[0009] Further preferably, the pulley limiting group is composed of a plurality of pulleys, a plurality of rotating shafts, a plurality of sliding grooves and a plurality of clamping push rods, wherein both ends of the rotating shaft are fixedly connected to the inner wall of the second connector on the same side, and the rotating shafts transversely penetrate the pulleys at corresponding positions, and the pulleys are arranged vertically and divided into four groups, and clamping push rods are provided on the outer walls of both sides of each group of vertically arranged pulleys.
[0010] Further preferably, a plurality of slide grooves are provided at the bottom of the pulley limiting group, and the slide grooves are slidably connected with the clamping push rod, and a plurality of U-shaped clamping plates corresponding to the vertically arranged pulleys are equidistantly provided on the rod body of the clamping push rod.
[0011] Further preferably, the contact surface between the U-shaped clamping plate of the clamping push rod and the pulley, and the contact surface between the limit rod and the first cable are both bonded with a rubber layer.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the utility model, the first connector and the second connector are connected to each other. At this time, a plurality of elastic connectors fixedly connected to the bottom of the first connector will be respectively inserted into the corresponding strip grooves and limit grooves. Because the elastic connector itself is composed of two elastic connectors, when the elastic connector is inserted into the strip groove and the limit groove in sequence, until the bottom end of the elastic connector contacts the bottom wall of the limit groove, the elastic connector will touch and squeeze the stop block on one side, so that the spring and the limit rod are pushed to slide along the inner wall of the limit groove until the top end of the limit rod contacts the outer wall of the first cable and no longer slides. During this period, because the elastic connector is always placed inside the limit groove, the limit rod limits the position of the first cable to prevent the first cable from falling off the first connector, and a soft rubber layer is bonded to the top end of the limit rod, so that the outer wall of the first cable will not be scratched.
[0014] In the utility model, when the second cable is passed through the interior of the second connector, the outer wall of the second cable will contact the pulley limiting group fixedly connected to the inner wall of the second connector. While the second cable is continuously passed upward, the pulleys arranged vertically in the pulley limiting group are also continuously rotating around the rotating shaft. Driven by the pulley, the second cable is also more likely to pass through the interior of the second connector. When the top end of the second cable reaches the top of the second connector, the clamping push rod can be pushed to approach the pulley. At this time, the U-shaped clamping plate provided on the rod body of the clamping push rod will clamp and fix the entire pulley corresponding thereto, so that the pulley can no longer rotate, thereby limiting the second cable from escaping from the second connector in the reverse direction, thereby fixing the position of the second cable, and a soft rubber layer is bonded to the contact between the U-shaped clamping plate and the outer wall of the pulley, so that the outer wall of the pulley will not be scratched.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 6 The utility model provides a technical solution: a coaxial connector with an internal limiting structure, including a first cable 1, the first cable 1 vertically penetrates the interior of a first connector 2, a plurality of elastic connectors 3 are fixedly connected to the bottom of the first connector 2, the bottom end of the elastic connector 3 is plugged into the interior of a limiting device 4, the bottom of the limiting device 4 is fixedly connected to the top of a second connector 5, a pulley limiting group 6 is fixedly connected to the inner wall of the second connector 5, and a second cable 7 vertically penetrates the interior of the second connector 5.
[0024] In this embodiment, Figure 1 and Figure 4 and Figure 5As shown, the limiting device 4 is composed of a top plate 401, a bottom plate 402, a stopper 403, a spring 404 and a limiting rod 405, wherein a plurality of strip grooves are provided at the bottom of the top plate 401, and a plurality of limiting grooves are provided at the top of the bottom plate 402, and the stopper 403 and the limiting rod 405 are fixedly connected as a whole through the spring 404, and the stopper 403 and the limiting rod 405 are slidably connected to the inside of the limiting groove by the whole formed by the spring 404, and the bottom of the top plate 401 is fixedly connected to the top of the bottom plate 402; it should be noted that after the first cable 1 and the second cable 7 are respectively passed through the inside of the first connector 2 and the second connector 5, the first connector 2 and the second connector 5 can be connected to each other, at this time, a plurality of elastic connectors 3 fixedly connected to the bottom of the first connector 2 will be respectively inserted into the corresponding strip grooves and limiting grooves, because the elastic connector 3 itself is composed of two elastic connectors The elastic connector 3 is composed of the strip groove and the limiting groove in turn, so when the elastic connector 3 is inserted into the strip groove and the limiting groove in turn, the distance between the two connectors will be compressed, so that the entire elastic connector 3 can be accommodated in the strip groove and the limiting groove. When the bottom end of the elastic connector 3 contacts the bottom wall of the limiting groove, the elastic connector 3 will touch the stop block 403 on one side. Because the stop block 403 and the limiting rod 405 are fixedly connected with the spring 404, the two connectors release the extrusion of the inner wall, restore the original spacing, and squeeze the stop block 403 in contact with it. At the same time, the spring 404 and the limiting rod 405 are squeezed and slide along the inner wall of the limiting groove until the top of the limiting rod 405 contacts the outer wall of the first cable 1 and no longer slides. During this period, because the elastic connector 3 is always placed in the limiting groove, the limiting rod 405 limits the position of the first cable 1 to prevent the first cable 1 from falling off from the first connector 2.
[0025] In this embodiment, Figure 4 and Figure 5As shown, the number of elastic connectors 3 is the same as that of the strip grooves and the limiting grooves; it should be noted that a plurality of elastic connectors 3 are fixedly connected to the bottom of the first connector 2, and are distributed in four directions in a cross shape, and the strip grooves and the limiting grooves are also in a cross shape, and are respectively distributed at the bottom of the top plate 401 and the top of the bottom plate 402, and the elastic connectors 3 in the four directions correspond to the positions of the strip grooves and the limiting grooves one by one, so when the first connector 2 with the first cable 1 inserted is connected to the second connector 5, the elastic connector 3 will be accurately inserted into the strip grooves and the limiting grooves corresponding to their positions, and the bottom end of the elastic connector 3 and the bottom wall of the limiting groove will be inserted into the elastic connector 3. When they come into contact, they will restore to their original width. At the same time, one side connector of the elastic connector 3 will push the block 403 on the same side due to the rebound force, and then push the spring 404 and the limiting rod 405, so that the limiting rod 405 slides along the inner wall of the limiting groove until it just contacts the outer wall of the first cable 1 and fits tightly against the outer wall of the first cable 1 to limit its position. When the first connector 2 is separated from the second connector 5, the elastic connector 3 can be taken out from the inside of the strip groove and the limiting groove in turn. At this time, the extrusion of the spring 404 is released, thereby driving the block 403 and the limiting rod 405 to rebound to their original position, thereby releasing the position limitation of the first cable 1.
[0026] In this embodiment, Figure 3 and Figure 6 As shown, the pulley limiting group 6 is composed of a plurality of pulleys 601, a plurality of rotating shafts 602, a plurality of sliding grooves 603 and a plurality of clamping push rods 604, wherein both ends of the rotating shaft 602 are fixedly connected to the inner wall of the second connector 5 on the same side, and the rotating shafts 602 are horizontally penetrated through the pulleys 601 at the corresponding positions, and the pulleys 601 are arranged vertically and divided into four groups, and the outer walls of both sides of each group of vertically arranged pulleys 601 are provided with clamping push rods 604; it should be noted that when the second cable 7 is passed through the inside of the second connector 5, the outer wall of the second cable 7 will contact the pulley limiting group 6 fixedly connected to the inner wall of the second connector 5, and while the second cable 7 is continuously passed upward, the pulley limiting group 6 The vertically arranged pulley 601 is also constantly rotating around the rotating shaft 602. Driven by the pulley 601, the second cable 7 is also easier to pass through the inside of the second connector 5. When the top end of the second cable 7 reaches the top of the second connector 5, the clamping push rod 604 can be pushed to approach the pulley 601. At this time, the clamping push rod 604 arranged on the outer walls of both sides of the vertically arranged pulley 601 changes from the original state of being separated from the outer walls of both sides of the pulley 601 to the state of contacting with the outer walls of both sides of the pulley 601, and clamps and fixes the pulley 601 at the corresponding position, so that the pulley 601 cannot rotate. At this time, the second cable 7 cannot be taken out of the second connector 5 in the reverse direction, thereby fixing the position of the second cable 7.
[0027] In this embodiment, Figure 3 and Figure 6 As shown, a plurality of slide grooves 603 are provided at the bottom of the pulley limit group 6, and the slide grooves 603 are slidably connected with the clamping push rod 604, and a plurality of U-shaped clamping plates corresponding to the vertically arranged pulleys 601 are equidistantly provided on the rod body of the clamping push rod 604; it should be noted that when the second cable 7 is inserted into the second connector 5 and passes through the interior of the second connector 5 to reach the top of the second connector 5, the bottom ends of the clamping push rods 604 in four directions can be manually pushed respectively, thereby driving the entire clamping push rod 604 It slides along the inner wall of the slide groove 603 slidably connected thereto, and continuously approaches the pulley 601 at the corresponding position until it contacts the outer walls on both sides of the pulley 601. Because the rod body of the clamping push rod 604 is equidistantly provided with a number of U-shaped clamping plates corresponding to the vertically arranged pulleys 601, the U-shaped clamping plates clamp and fix the entire corresponding pulley 601, so that the pulley 601 can no longer rotate, thereby limiting the second cable 7 from escaping from the second connector 5 in the reverse direction, thereby fixing the position of the second cable 7.
[0028] In this embodiment, Figure 2 and Figure 6 As shown, the contact surface between the U-shaped clamping plate of the clamping push rod 604 and the pulley 601, and the contact surface between the limiting rod 405 and the first cable 1 are all bonded with a rubber layer; it should be noted that when the first connector 2 and the second connector 5 are connected to each other, the plurality of elastic connectors 3 provided at the bottom of the first connector 2 will be respectively inserted into the corresponding strip grooves and limiting grooves, and until they contact the bottom wall of the limiting groove, and at the same time push the stop block 403, the spring 404 and the limiting rod 405 on one side to slide along the inner wall of the limiting groove, and finally make the top end of the limiting rod 405 contact the first cable 1 , and when the second cable 7 is passed from the inside of the second connector 5 to the top of the second connector 5, the clamping push rod 604 is pushed to slide along the inner wall of the slide groove 603, so that the U-shaped clamping plate provided on the rod body of the clamping push rod 604 clamps and fixes the corresponding pulley 601. When the above steps are completed, since the top ends of the U-shaped clamping plate and the limiting rod 405 are bonded with a soft rubber layer, the U-shaped clamping plate and the limiting rod 405 are in contact with the outer walls of the first cable 1 and the pulley 601 respectively, their outer walls will not be scratched, and the repeated use of the equipment will not be affected.
[0029] The use method and advantages of the utility model: When the coaxial connector with an internal limit structure is used, the working process is as follows:
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when the second cable 7 is first passed through the interior of the second connector 5, the outer wall of the second cable 7 will contact the pulley limiting group 6 fixedly connected to the inner wall of the second connector 5. While the second cable 7 is continuously passed upward, the pulley 601 arranged vertically in the pulley limiting group 6 is also continuously rotating around the rotating shaft 602. Driven by the pulley 601, the second cable 7 is also more likely to pass through the interior of the second connector 5. When the top end of the second cable 7 reaches the top of the second connector 5, the U-shaped clamping plate can be pushed to approach the pulley 601 and clamp the corresponding entire pulley 601, so that the pulley 601 can no longer rotate, thereby limiting the second cable 7 from escaping from the second connector 5 in the reverse direction, thereby fixing the position of the second cable 7. Then, the first cable 1 is passed through the first connector 2, and the first connector 2 and the second connector 5 are connected to each other. At this time, several elastic connectors 3 fixedly connected to the bottom of the first connector 2 will be inserted into the corresponding strip grooves and limit grooves respectively, until the bottom end of the elastic connector 3 contacts the bottom wall of the limit groove, the elastic connector 3 will touch and squeeze the stop block 403 on one side. At the same time, the spring 404 and the limit rod 405 are pushed to slide along the inner wall of the limit groove until the top of the limit rod 405 contacts the outer wall of the first cable 1 and stops sliding. During this period, because the elastic connector 3 is always placed inside the limit groove, the limit rod 405 limits the position of the first cable 1 to prevent the first cable 1 from falling off the first connector 2.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
