Abstract

The invention provides a connector and electronic equipment. The connector comprises a sealing piece, a first shell, a second shell and a rotating piece. The sealing member is provided with a through hole for a cable to pass through, and the sealing member is fixedly connected with the first housing. The second shell is provided with an abutting face arranged towards the periphery of the sealing piece, and an included angle is formed between the abutting face and the axis of the through hole. The rotating part is rotatably arranged on the second shell, and the rotating part is connected with the first shell and used for enabling the first shell and the second shell to relatively move in the axial direction of the through hole. When the rotating piece rotates to the first position, the abutting face abuts against the periphery of the sealing ring so that the inner wall of the through hole can be attached to the cable in a sealed mode.

Description

Technical Field

[0001] The present application relates to the technical field of cable connection equipment, and in particular to a connector and an electronic device. Background Art

[0002] When a cable is connected to a device, a connector needs to be provided at one end of the cable to be connected so that the cable and the device can form an electrical connection.

[0003] When the connector is used outdoors, it will be exposed to a humid environment if it encounters rain or snow. Since there is a risk of poor contact between the connector and the cable when exposed to moisture or water, the connector and the cable have been designed to be moisture-proof and waterproof. Conventional connectors usually include a waterproof component that fits the cable to achieve a waterproof function. During installation, a screwing method is usually used to achieve a closed connection between the cable and the connector. Since the number of turns is large and the time is long, the construction workers cannot ensure that the screwing is in place, which will cause waterproof failure. Therefore, it is necessary to provide a connector that is easy to install. Summary of the invention

[0004] The present application provides a connector and an electronic device, wherein the connector is easy to install and has a reliable waterproof effect.

[0005] In the first aspect, the present application provides a connector, which includes a seal, a first shell, a second shell and a rotating member. The seal has a through hole for the cable to pass through, and the seal is fixedly connected to the first shell. The second shell has a push surface arranged toward the outer periphery of the seal, and the push surface forms an angle with the axis of the through hole. The rotating member is rotatably arranged on the second shell, and the rotating member is connected to the first shell, and is used to make the first shell and the second shell move relative to each other along the axial direction of the through hole. Among them, when the rotating member is rotated to the first position, the push surface pushes against the outer periphery of the sealing ring to make the inner wall of the through hole fit tightly with the cable. In the above embodiment, the operation of flipping the rotating member to lock the connector is more convenient and more accurate than the traditional operation of screwing the connecting nut to lock the connector, which reduces the situation where the connecting nut is not turned enough times so that the seal is not shrunk into place and causes waterproof failure, and the rotating member is flipped into place once, making the connection of the connector more reliable.

[0006] In one embodiment, the connector further comprises a clamping member, which comprises a cylinder and a plurality of claws located at one end of the cylinder, wherein the plurality of claws are arranged at intervals around the axis of the cylinder. The cylinder is fixedly connected to the first shell. The sealing member is fixed within the outline formed by the cylinder and the plurality of claws, and the outer peripheral surface of the sealing member is fitted with the inner cylinder wall of the cylinder. The push surface is used to push the outer periphery of the sealing member by pushing the plurality of claws. The clamping member shrinks under the pressure of the push surface, thereby fitting the sealing member to the outer wall of the cable, which is conducive to improving the fitting effect of the sealing member.

[0007] In one embodiment, the second shell includes a cylindrical portion, and the push surface is located on the inner wall of the cylindrical portion, which can make the seal evenly stressed and have a better shrinkage effect, thereby achieving a good waterproof effect.

[0008] In one embodiment, the rotating member includes a first plate body and a second plate body arranged opposite to each other, the first plate body has a first fixing hole, and the second plate body has a second fixing hole. The second shell includes a first side wall and a second side wall that are separated from each other, the first side wall has a first fixing shaft, the second side wall has a second fixing shaft, and the axes of the first fixing shaft and the second fixing shaft coincide. The first fixing shaft is inserted into the first fixing hole, and the second fixing shaft is inserted into the second fixing hole, so as to realize the rotational connection between the rotating member and the second shell.

[0009] In one embodiment, the rotating member further includes a third plate body connected between the first plate body and the second plate body, and the third plate body can drive the first plate body and the second plate body to rotate simultaneously. The second shell includes a third side wall connected between the first side wall and the second side wall. The first plate body and the second plate body are respectively connected to the third plate body to form a receiving groove. When the rotating member rotates to the first position, the third plate body fits the third side wall, and the second shell is located in the receiving groove, thereby improving the integrity of the connector.

[0010] In one embodiment, the rotating member includes a slide groove and a positioning groove at one end of the slide groove; the first housing includes a convex shaft, and the convex shaft is slidably arranged in the slide groove. When the rotating member rotates to the first position, the convex shaft slides into the positioning groove, so that the operator can visually check whether the rotating member is rotated in place, thereby improving the reliability of connector assembly.

[0011] In one embodiment, there is a protrusion between the slide groove and the positioning groove, which is used to prevent the convex shaft from sliding out of the positioning groove, thereby reducing the situation where the rotating part is accidentally opened in bad weather or misoperation.

[0012] In one embodiment, when the rotating member rotates to the first position, the convex shaft, the positioning groove and the rotation center of the rotating member are located in the same straight line, and the straight line is parallel to the axis of the through hole, thereby forming a self-locking structure. When there is bad weather such as wind in the environment, a relative sliding force may be generated between the first shell and the second shell. That is, a force along the axis direction of the through hole will be generated between the convex shaft and the positioning groove. Since the rotation centers of the convex shaft, the positioning groove and the rotating member are located in the same straight line, the force between the convex shaft and the positioning groove will not drive the rotating member to rotate around the rotation center, thereby having a self-locking effect.

[0013] In one embodiment, the slide groove is an arc-shaped groove, and the slide groove has a first end and a second end; the positioning groove is located at the second end, and the distance between the second end and the rotation center of the rotating member is smaller than the distance between the first end and the rotation center of the rotating member. The second end is closer to the rotation center of the rotating member than the first end, and when the rotating member is turned over for locking, the convex shaft slides from the first end of the slide groove to the second end, thereby realizing relative sliding between the first shell and the second shell, so that the push surface exerts an effective force on the sealing ring.

[0014] In one embodiment, the connector further comprises a sealing ring. The first housing comprises a fixed shell and an inner shell, and the inner shell is fixedly connected to the fixed shell. The fixed shell is used to be fixedly connected to the device to be connected. The sealing ring is located between the fixed shell and the inner shell, and the sealing ring is tightly fitted to the fixed shell and the inner shell to reduce the situation where external water vapor enters the connector from between the fixed shell and the inner shell.

[0015] In one embodiment, the connector further includes a conductive terminal, which is fixedly connected to the first housing and is used to connect to a conductor in the cable to achieve electrical connection between the cable and the device to be connected.

[0016] On the other hand, an embodiment of the present application further provides an electronic device, the electronic device comprising a housing and the above connector, the above first housing being fixedly connected to the housing, so that the connector can be effectively fixed to the housing of the electronic device. Since the locking operation of the above connector is simple and the waterproof effect is reliable, the reliability of the electronic device can be effectively improved.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments described herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all illustrated by taking the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship, and they do not represent the true proportion.

[0030] It should be noted that specific details are described in the following description to facilitate understanding of the present application. However, the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0031] In order to facilitate understanding of the connector and electronic device provided in the embodiments of the present application, their application scenarios are first introduced below.

[0032] Outdoor equipment generally includes base stations, outdoor routers, and outdoor power supplies, such as active antenna units (AAU, ActiveAntenna Unit), optical line terminals (OLT, Optical Line Terminal), etc. The above-mentioned outdoor equipment generally needs to be connected to the cable using a connector. Since the equipment is exposed to the outdoor environment, a waterproof component needs to be set in the connector to prevent water vapor from entering the connector and causing a short circuit in rainy and snowy weather. The current outdoor connector generally uses a waterproof joint as a waterproof component. The waterproof joint includes a connecting nut and a rubber ring. During installation, the connecting nut needs to be tightened to compress the rubber ring so that the rubber ring fits the cable to achieve sealing and waterproofing. Outdoor equipment is usually installed at a high position. Construction personnel need to work at high altitude when installing the connector, and need to manually or with the help of tools to screw the connecting nut. The connecting nut needs to be screwed in many turns, and the construction time is long. In addition, the construction personnel cannot ensure that the connecting nut is screwed in place under the above environment, and there may be insufficient number of turns, resulting in the waterproof joint not clamping the cable, resulting in waterproof failure. Waterproof failure can cause a short circuit, and the connection reliability of the connector cannot be guaranteed. In addition, if the waterproof connector does not clamp the cable, when the cable is subjected to external force, the external force will be directly transmitted to the cable's battery core and the conductive structure of the connector, which may easily cause poor contact or even disconnection between the cable and the conductive structure.

[0033] To solve the above problems, an embodiment of the present application provides a connector. Figure 1 FIG. 1 is a schematic diagram of the structure of a connector in an embodiment of the present application. Figure 1As shown, the connector includes a first shell 1, a seal 2, a second shell 3 and a rotating member 4. The seal 2 has a through hole for the cable to pass through. There is a gap between the outer wall of the cable 100 and the hole wall of the through hole, and the gap may cause water vapor to enter the connector. The seal 2 is fixedly connected to the first shell 1. The second shell 3 has a push surface 321 arranged toward the outer periphery of the seal 2, and the push surface 321 forms an angle with the axis O of the through hole. The rotating member 4 is rotatably arranged on the second shell 3, and the rotating member 4 is connected to the first shell 1, and is used to make the first shell 1 and the second shell 3 move relative to each other along the axial direction of the through hole. When the rotating member 4 rotates to the first position, the push surface 321 pushes the outer periphery of the seal 2, causing the seal 2 to deform and shrink, so that the hole wall of the through hole is tightly fitted with the cable, which can prevent water vapor from entering the connector from the gap between the connector and the cable 100, thereby achieving a waterproof effect. The rotating member 4 is in the locked state of the connector when in the first position. When the connector is disassembled, the rotating member 4 is reversed and rotated from the first position to the second position. When the rotating member 4 is in the second position, the connector is in an open state. The first housing 1 and the second housing 3 slide relative to each other in opposite directions, so that the push surface 321 is away from the sealing member 2. The sealing member 2 extends back to the initial state to release the cable, and the cable can be taken out.

[0034] It should be noted that the first position mentioned above can be a specific position or a range. That is, the position where the rotating member 4 rotates to make the pushing surface 321 push against the sealing member 2 and the hole wall of the sealing member 2 fits the outer wall of the cable 100 can be understood as the first position. In addition, the second position mentioned above refers to all positions within the range of motion of the rotating member 4 other than the first position.

[0035] In the above embodiment, when locking or opening the connector, the operation of flipping the rotating part 4 is more convenient and more accurate than the operation of screwing the connecting nut in the prior art, which reduces the situation where the connecting nut is not screwed enough times so that the seal 2 does not shrink into place and causes waterproof failure, making the connection of the connector more reliable.

[0036] When the sealing member 2 is specifically selected, an elastic rubber ring can be used as the sealing member 2. The rubber ring contracts and compresses the cable under the pressure of the push surface 321, and the waterproof effect is better.

[0037] exist Figure 1 In the example shown in FIG, only a simplified structural diagram of a connector is shown. In practical applications, the specific structural types of the connector may be various.

[0038] For example, Figure 2 and Figure 3 shown. Figure 2 This is an exploded view of a connector in one embodiment of the present application. Figure 3 This is an assembly diagram of the rotating member and the second housing in one embodiment of the present application. Figure 2 and Figure 3 In one embodiment, the overall shape of the connector is roughly square. The second shell 3 includes a body 31, the cross section of the body 31 can also be square, the body 31 includes a first side wall 311 and a second side wall 312 that are separated from each other, wherein the first side wall 311 has a first fixed axis 3111, the second side wall 312 has a second fixed axis (not shown in the figure), and the axis centers of the first fixed axis 3111 and the second fixed axis coincide. The rotating member 4 includes a first plate body 41 and a second plate body 42 that are arranged opposite to each other, the first plate body 41 has a first fixed hole 411, and the second plate body 42 has a second fixed hole 412. The first fixed axis 3111 is inserted into the first fixed hole 411, and the second fixed axis is inserted into the second fixed hole 412. The first fixed axis 3111 and the second fixed axis are the rotation centers of the rotating member 4. The rotating member 4 is connected to the second shell 3 in rotation.

[0039] In order to realize the synchronous rotation of the first plate body 41 and the second plate body 42, the rotating member 4 further includes a third plate body 43 connected between the first plate body 41 and the second plate body 42. The first plate body 41, the second plate body 42 and the third plate body 43 are connected to each other to form a receiving groove. The body 31 of the second shell 3 further includes a third side wall 313 connected between the first side wall 311 and the second side wall 312. When the rotating member 4 rotates to the first position, the rotating member 4 is buckled with the body 31, and the body 31 is located in the receiving groove, that is, the third plate body 43 is in contact with the third side wall 313, thereby improving the integrity of the connector. Or it can be understood that when the rotating member 4 rotates to the first position, the third plate body 43 is substantially in contact with the third side wall 313. When the staff locks the connector, they can know whether the rotating member 4 is rotated in place by judging whether the third plate body 43 is in contact with or substantially in contact with the third side wall 313, so that the locking state of the connector can be intuitively judged.

[0040] In one embodiment, a paddle 45 may be further provided on the edge of the third plate 43 away from the first fixing hole 411 and the second fixing hole 412. When the rotating member 4 is located at the first position, an acute angle is formed between the paddle 45 and the third side wall 313, so as to facilitate lifting the rotating member 4 and flip it from the first position to the second position, so that the second shell 3 and the first shell 1 slide relative to each other in opposite directions, so that the sealing member 2 is released from the cable 100.

[0041] In practical applications, the connection between the rotating member 4 and the first shell 1 can be various, so that the rotating member 4 can drive the first shell 1 to move relative to the second shell 3. For example, in an example provided in the present application, the rotating member 4 and the first shell 1 are connected by sliding to achieve relative movement between the first shell 1 and the second shell 3.

[0042] Figure 4 FIG. 1 is an assembly diagram of a rotating member, a first shell and a second shell in one embodiment of the present application. Figure 2 , Figure 3 and Figure 4 In one embodiment, the rotating member 4 includes a slide groove 46. Specifically, the number of the slide grooves 46 can be two, and the two slide grooves 46 are respectively arranged on the first plate body 41 and the second plate body 42 of the rotating member 4. The slide grooves 46 are arranged on the first plate body 41 and the second plate body 42 so that the rotating member 4 is subjected to an even force. The slide groove 46 is an arc groove, which is bent toward the first fixing hole 411 and the second fixing hole 412. The slide groove 46 is located on the side of the first fixing hole 411 and the second fixing hole 412 away from the second housing 3. The first housing 1 includes a convex shaft 13, which is slidably arranged in the slide groove 46. The slide groove 46 has a first end A and a second end B. When the rotating member 4 is located at the second position, the convex shaft 13 is located at the first end A. When the rotating member 4 rotates around the rotation center to the first position, the convex shaft 13 slides from the first end A to the second end B along the slide groove 46. When the rotating member 4 is located at the first position, the convex shaft 13 is located at the second end B. It is worth noting that the above-mentioned slide groove 46 can also be only provided on the first plate body 41 , or only provided on the second plate body 42 , which can also achieve the effect that the rotating member 4 drives the first shell 1 and the second shell 3 to slide relative to each other.

[0043] Please continue to refer to Figure 4 In one embodiment, a positioning groove 461 is provided at one end of the slide groove 46, and the positioning groove 461 can be specifically located at the second end B. When the rotating member 4 rotates to the first position, the convex shaft 13 slides into the positioning groove 461. In addition, in the example provided in the present application, there is a protrusion 4611 between the slide groove 46 and the positioning groove 461, and the protrusion 4611 can play a certain blocking role on the convex shaft 13, and can prevent the convex shaft 13 from accidentally sliding out of the positioning groove 461. The above-mentioned arc groove has two arc edges parallel to each other, and the protrusion 4611 can be specifically located on the arc edge of the slide groove 46.

[0044] By providing the protrusion 4611, the locking effect of the connector can be improved, and the efficiency of the staff in locking the connector can also be improved. Specifically, when locking the connector, the staff rotates the rotating member 4. When the convex shaft 13 of the rotating member 4 passes over the protrusion 4611 and slides into the positioning groove 461, obvious resistance will be generated. The resistance will be transmitted to the human hand, so that the staff can sense whether the rotating member 4 is rotated into place. In addition, in actual use, when the connector is exposed to bad weather such as wind, the wind-driven rotating member 4 may be subjected to the force of rotation. Under the limiting effect of the protrusion 4611, the convex shaft 13 of the rotating member 4 is not easy to slide out of the positioning groove 461, so the locking effect of the connector can be effectively improved.

[0045] In addition, in an example provided in the present application, when the convex shaft 13 is located in the positioning groove 461, the protrusion 4611 clamps the convex shaft 13 in the positioning groove 461. At this time, the rotation centers of the convex shaft 13, the positioning groove 461 and the rotating member 4 are located in the same straight line, and the straight line is parallel to the axis of the through hole, thereby forming a self-locking structure. When there is bad weather such as wind in the environment, a relative sliding force may be generated between the first shell 1 and the second shell 3. That is, a force along the axis direction of the through hole will be generated between the convex shaft 13 and the positioning groove 461. Since the rotation centers of the convex shaft 13, the positioning groove 461 and the rotating member 4 are located in the same straight line, the force between the convex shaft 13 and the positioning groove 461 will not drive the rotating member 4 to rotate around the rotation center, thereby having a self-locking effect.

[0046] Figure 5 FIG. 1 is a schematic diagram of the structure of a rotating member in another embodiment of the present application. Figure 2 and Figure 5 , there is another installation method for the installation position of the rotating member 4. The opening position of the slide groove 46 of the rotating member 4 needs to be adjusted accordingly according to the installation position. In another embodiment, the positions of the slide groove 46 and the positioning groove 461 on the rotating member 4 are opposite to those in the above embodiment, that is, the slide groove 46 and the positioning groove 461 are located on the side of the first fixing hole 411 and the second fixing hole 412 close to the second shell 3. The rotating member 4 is rotatably connected to the first shell 1 and connected to the second shell 3. Specifically, the convex shaft 13 is inserted into the first fixing hole 411 and the second fixing hole 412 to realize the rotation connection between the rotating member 4 and the first shell 1. The first fixed shaft 3111 and the second fixed shaft are inserted into the slide groove 46. In this embodiment, the convex shaft 13 is used as the rotation center of the rotating member 4. When the rotating member 4 is located at the first position, the first fixed shaft 3111 and the second fixed shaft slide into the positioning groove 461. At this time, the protruding shaft 13 , the positioning groove 461 and the first fixed shaft 3111 are located in the same straight line, and the straight line is parallel to the axis of the through hole of the sealing member 2 .

[0047] In some of the above embodiments, the distance a between the first end A of the slide slot 46 and the rotation center of the rotating member 4 and the distance b between the second end B and the rotation center of the rotating member 4 satisfy a>b. During the rotation of the rotating member 4, the first shell 1 and the second shell 3 move relative to each other, and the relative movement distance of the first shell 1 and the second shell 3 is s, s=ab.

[0048] Figure 6 is a cross-sectional view of a connector in an open state in one embodiment of the present application, Figure 7 This is a cross-sectional view of a connector in a locked state in an embodiment of the present application. Figure 2 , Figure 6 and Figure 7 In one embodiment, the first shell 1 may include a fixed shell 11 and an inner shell 12. One end of the inner shell 12 is connected to the fixed shell 11, and the other end is connected to the seal 2. The fixed shell 11 may specifically be a flange, and the flange is used to fix the connector to the device to be connected. The second shell 3 has a accommodating cavity, and the shape of the inner shell 12 is adapted to the shape of the accommodating cavity of the second shell 3, and the inner shell 12 is slidably installed in the accommodating cavity. The convex shaft 13 is located on both sides of the fixed shell 11, and the second shell 3 and the fixed shell 11 are respectively connected to the rotating member 4. After the fixed shell 11 is fixedly connected to the device to be connected, the rotating member 4 is flipped to the first position, and the rotating member 4 drives the second shell 3 to approach the fixed shell 11, so that the seal 2 shrinks and clamps the cable 100.

[0049] Since the fixed shell 11 is fixedly connected to the inner shell 12, and the fixed shell 11 is connected to the device to be connected, the inner shell 12 remains stationary during the process of the second shell 3 gradually approaching the fixed shell 11. The second shell 3 moves relative to the inner shell 12, and the seal 2 connected to the inner shell 12 is squeezed and contracted by the push surface 321 of the second shell 3, thereby clamping the cable 100. At this time, the seal 2 and the cable 100 have an interference fit. The rotating member 4 is flipped from the first position to the second position, and the rotating member 4 drives the second shell 3 away from the fixed shell 11. At this time, the seal 2 in the contracted state is released and opened, thereby loosening the cable 100 and the seal 2, which is convenient for removing the cable 100.

[0050] Figure 8 This is an assembly diagram of a clamping member and a sealing member in one embodiment of the present application, combined with Figure 2 , Figure 6 , Figure 7 and Figure 8In order to make the seal 2 shrink better, in one embodiment, the connector may further include a clamping member 21. The clamping member 21 includes a cylinder 211 and a plurality of claws 212 located at one end of the cylinder 211, and the plurality of claws 212 are arranged at intervals around the axis of the cylinder 211 and extend in the axial direction of the cylinder 211. The cylinder 211 is fixedly connected to the inner shell 12 of the first shell 1, and the seal 2 is fixed in the contour surrounded by the cylinder 211 and the plurality of claws 212, and the outer peripheral surface of the seal 2 is in contact with the inner cylinder wall of the cylinder 211. The clamping member 21 forms a shrinking ring, and two adjacent claws 212 are spaced apart by a preset distance, so that the shrinking ring has a certain amount of compression. The clamping member 21 can shrink under the action of an external force, and the external force is the external force applied by the push surface 321.

[0051] Please continue to refer to Figure 6 and Figure 7 In one embodiment, each of the above-mentioned claws 212 has a fixed tooth 2121 on the side facing the seal 2, and the seal 2 is provided with a groove 221 on the side facing the claw 212 for engaging with the fixed tooth 2121. The seal 2 is arranged in the clamping member 21, and the fixed tooth 2121 is engaged with the groove 221, which can prevent the seal 2 and the inner shell 12 from sliding relative to each other in the axial direction during the movement of the inner shell 12, resulting in the seal 2 falling off.

[0052] Fig. 9 This is a cross-sectional view of the second shell in one embodiment of the present application. Figure 2 , Figure 6 and Fig. 9 In one embodiment, the second shell 3 further comprises a cylindrical portion 32, which is connected to the body 31 and is located at one end of the body 31 away from the first shell 1, and the clamping member 21 and the sealing member 2 are both located in the cylindrical portion 32. The push surface 321 is located at the inner wall of the cylindrical portion 32, and the push surface 321 forms an acute angle with the axis of the through hole, that is, the push surface 321 is a conical surface, and the diameter of the conical surface gradually decreases along the first direction M, and the first direction M is the direction in which the second shell 3 is away from the first shell 1. The end of the sealing member 2 and the end of the claw 212 respectively abut against the conical surface. In the process of the rotating member 4 rotating to the first position, the sealing member 2 and the claw 212 slide along the conical surface. As the diameter of the conical surface gradually decreases, the sealing member 2 shrinks under the extrusion of the push surface 321 and the clamping member 21. The conical surface enables the seal 2 to shrink in both the axial and radial directions, and the force is evenly applied, resulting in a better shrinkage effect, thereby improving the waterproof effect.

[0053] The cylindrical portion 32 has a threading hole 322 for passing the cable 100. There is a gap between the outer wall of the cable 100 and the hole wall of the threading hole 322. When the seal 2 and the clamping member 21 are assembled, the seal 2 is extended toward the push surface 321 by a preset distance of the clamping member 21, that is, the distance between the end of the seal 2 and the threading hole 322 along the first direction M is shorter than the distance between the end of the claw 212 and the threading hole 322. When the push surface 321 pushes the seal 2 and the clamping member 21, the seal 2 can not only block the gap between the outer wall of the cable 100 and the through hole of the seal 2, but also block the gap between the outer wall of the cable 100 and the hole wall of the threading hole 322, thereby preventing water vapor from entering the connector.

[0054] Please continue to refer to Figure 2 and Figure 7 In one embodiment, the connector further includes a conductive terminal 5, which is fixedly connected to the first housing 1, and is used to connect to a conductor (not shown) in the cable 100. Specifically, the conductive terminal 5 is installed in the inner housing 12, and the conductive terminal 5 includes an inner core 51 and a wire clamp 52, the inner core 51 is used to fix the conductor in the cable 100, and the wire clamp 52 is used to clamp the cable 100. The wire clamp 52 is fixedly installed on the side of the inner core 51 facing the clamping member 21. During assembly, the cable 100 is fixed with the wire clamp 52, and then the outer skin of part of the cable 100 is peeled off to expose the conductor. Then, after the conductor is fixed to the inner core 51, the conductive terminal 5 is inserted into the inner housing 12.

[0055] Please continue to refer to Figure 2 and Figure 7 In one embodiment, the inner shell 12 has a plug-in column 24 on the side facing the fixed shell 11. The cross section of the inner shell 12 may be square, and the edge of the inner shell 12 facing the fixed shell 11 has four corners. The number of the plug-in columns 24 may be four, and the four plug-in columns 24 are respectively arranged on the edge of the inner shell 12 facing the flange 1, and are located at the four corners of the edge. During assembly, the plug-in column 24 is extended into the fixed shell 11 to fix the inner shell 12 to the fixed shell 11.

[0056] In another embodiment, a plug sleeve (not shown) can be used to replace the plug post 24. The plug sleeve is in the shape of a sleeve and is located at the edge of the inner shell 12 facing the fixed shell 11. During assembly, the plug sleeve extends into the flange 1.

[0057] Please combine Figure 2 and Figure 7In order to improve the sealing performance of the connector, in one embodiment, the connector further includes a sealing ring 6, which is located between the fixed shell 11 and the inner shell 12, and the sealing ring 6 is sealed and fitted with both the fixed shell 11 and the inner shell 12. Specifically, a first groove 231 is provided on the surface of the inner shell 12 at one end facing the fixed shell 11, and the sealing ring 6 can be embedded in the first groove 231. When the rotating member 4 is in the first position, the end face of the fixed shell 11 contacts the sealing ring 6. Or in another embodiment, a second groove 14 is provided on the end face of the fixed shell 11 at one end facing the second shell 3, and the sealing ring 6 is embedded in the first groove 231. When the rotating member 4 is in the first position, part of the sealing ring 6 is located in the second groove 14, and the waterproof effect is better.
