Description

Technical Field

[0001] The present application relates to the field of cable accessories, and in particular to a quick-plug shielded connector and a method of using the same. Background Art

[0002] Electrical equipment and shielded cables can be connected through a connector, which is called a detachable connector and is connected to the outer cone sleeve of the electrical equipment.

[0003] In the related art, a detachable connector includes a T-shaped connector body, which includes a horizontally arranged first main body and a vertically arranged second main body below the first main body. The second main body of the connector body is provided with an installation groove for installing a stress cone, and the installation groove is provided with a stress cone. The stress cone is provided with a slot for inserting a cable. The cable includes a conductor, an insulation layer wrapped around the conductor, a semiconducting layer wrapped around the insulation layer, and a metal shielding layer wrapped around the semiconducting layer. The cable is stripped to expose the core, insulation layer, semiconducting layer, and metal shielding layer. The top of the slot is provided with a first perforation for the conductor to pass through, and the top of the insulation layer abuts against the top of the slot. The top of the installation groove is provided with a second perforation for connecting the first and second main bodies. The second perforation is provided with a terminal block, and the terminal block can be inserted into the first main body through the second perforation. The two ends of the first main body are provided with an electrical device connection terminal and an insulation plug, respectively. The electrical device connection terminal, the insulation plug, and the terminal block are fixedly connected by a stud bolt assembly.

[0004] Since the length of the cable inserted into the stress cone is limited, when plugging the cable, it is necessary to wrap tape on the position of the cable insertion length to make a positioning mark before assembly, then pass the cable through the stress cone to the mark, and then crimp the terminal on the conductor, and then insert the cable with the crimped terminal and the stress cone into the installation groove, and then insert the electrical equipment connection end into the first main body, pass the stud bolt through the terminal and the electrical equipment connection end, and then lock the terminal with a nut, and then screw the insulating plug on the other end of the stud bolt, and finally put on the shielding cap, and ground the ground wire, so as to realize the electrical connection between the cable and the electrical equipment.

[0005] The above assembly operation is troublesome, time-consuming and labor-intensive, so a quick-plug connector is needed to quickly plug cables and improve the efficiency of cable plugging. Summary of the Invention

[0006] In order to improve the above problems, the present application provides a quick-plug shielded connector and a method for using the same.

[0007] In a first aspect, the present application provides a quick-plug shielded connector, comprising a connector body, the connector body comprising a horizontally arranged first main body portion and a vertically arranged second main body portion below the first main body portion, wherein both ends of the first main body portion are respectively provided with an electrical equipment connection terminal and an insulating plug;

[0009] The stress cone includes two symmetrical unit cones, which form a whole after being assembled. The two unit cones move in the direction of approaching or moving away from each other. A fixed block is fixedly arranged below the second main body. Two fixed blocks are symmetrically arranged along the radial direction of the second main body. A positioning ring is arranged between the two fixed blocks. The positioning ring is rotatably connected to the fixed block. A tightening block is arranged in the fixed block. The positioning ring can be rotated until the tightening block tightens the stress cone and the cable. The positioning ring can also be rotated until the tightening block is separated from the stress cone.

[0010] By adopting the above technical solution, when inserting the cable, since the stress cone is composed of two separate pieces, there is a gap between the stress cone and the cable, which facilitates the insertion of the cable. The setting of the steps provides automatic positioning of the insertion position of the cable, and there is no need to make positioning marks. Finally, the positioning ring is rotated to make the tightening block press against the stress cone and the cable, so that the cable and the connector can be quickly plugged in and a stable connection is maintained. When the cable needs to be unplugged, the positioning ring is rotated until the tightening block loosens the stress cone, which is convenient to operate.

[0011] Preferably, a guide block is provided on the top surface of the stress cone, the guide block is T-shaped, a guide groove is opened on the top wall of the mounting groove, the guide groove is adapted to the shape of the guide block, and the guide block slides in the guide groove.

[0012] By adopting the above technical solution, the stress cone is located in the second main body and cannot be separated from the joint body.

[0013] Preferably, the longitudinal section of the fixing block is L-shaped, and the fixing block is provided with an accommodating groove for the pressing block to slide toward or away from the stress cone, and a rotating groove for the positioning ring to rotate;

[0014] The abutting block includes an upper portion abutting against the unit cone and a lower portion abutting against the metal shielding layer of the cable;

[0015] The clamping block is located in the middle of the axial direction of the positioning ring, and a contact wedge surface is provided on one side of the clamping block in the width direction. A yield groove is provided on the positioning ring, and a trigger wedge surface that cooperates with the contact wedge surface is provided on one side of the yield groove. The positioning ring is rotated to make the trigger wedge surface push the contact wedge surface. When the trigger wedge surface pushes the contact wedge surface, the clamping block is pushed in the direction close to the stress cone until the inner circumferential wall of the positioning ring and the outer circumferential wall of the clamping block are in interference fit, the inner circumferential wall of the upper part of the clamping block and the outer circumferential wall of the unit cone are in interference fit, and the inner circumferential wall of the lower part of the clamping block and the circumferential wall of the metal shielding layer are in interference fit;

[0016] After the positioning ring is rotated in the reverse direction, the triggering wedge surface is separated from the contact wedge surface, and the pressing block loses its pressing force on the stress cone and the cable.

[0017] By adopting the above technical solution, the positioning ring is rotated to make the trigger wedge surface push the contact wedge surface, and when the trigger wedge surface pushes the contact wedge surface, the clamping block is pushed toward the direction close to the stress cone until the inner circumferential wall of the positioning ring and the outer circumferential wall of the clamping block are in interference fit, the inner circumferential wall of the upper part of the clamping block and the outer circumferential wall of the unit cone are in interference fit, and the inner circumferential wall of the lower part of the clamping block and the circumferential wall of the metal shielding layer are in interference fit, thereby locking the stress cone and the cable, improving the connection tightness of the stress cone and the cable, and avoiding displacement between the stress cone and the cable to cause stress evacuation;

[0018] After the positioning ring is rotated in the reverse direction, the trigger wedge surface is separated from the contact wedge surface, and the tightening block loses its tightening force on the stress cone and the cable, making it easier to pull out the cable.

[0019] Preferably, a limiting block is provided on the bottom surface of the pressing block, and a limiting groove for the limiting block to slide is opened on the inner bottom wall of the accommodating groove.

[0020] By adopting the above technical solution, a guide limit is provided for the sliding of the pressing block toward or away from the stress cone, and the pressing block cannot be separated from the fixed block.

[0021] Preferably, a tension spring is provided in the accommodating groove, one end of the tension spring is fixedly connected to the inner wall of the accommodating groove, and the other end of the tension spring is fixedly connected to the clamping block. The tension spring applies a force to the clamping block to make the clamping block move in a direction away from the stress cone. The tension force of the tension spring on the clamping block is smaller than the friction force caused by the interference fit between the positioning ring and the clamping block, the clamping block and the unit cone, and the clamping block and the metal shielding layer.

[0022] By adopting the above technical solution, when there is no positioning ring to limit the position, the tension spring pulls the pressing block in a direction away from the stress cone, so that the pressing block is not likely to hinder the insertion of the cable.

[0023] Preferably, a pressing component for pressing the middle part of the stress cone in the axial direction is further provided inside the second main body, and the pressing component corresponds to the unit cone in a one-to-one manner.

[0024] The top end of the sliding arm is fixedly provided with a first end in contact with the second end of the sliding arm, and the bottom end of the sliding arm is connected with the second end of the sliding arm to the third trough.

[0025] A compression spring is provided at the bottom end of the swing arm, one end of the compression spring is fixedly connected to the inner wall of the third slot body, and the other end of the compression spring is fixedly connected to the abutment. The compression spring applies a force to the bottom end of the swing arm to move the bottom end of the swing arm toward the direction close to the unit cone, so that the abutment does not hinder the cable from being inserted into the slot during the process of inserting the cable into the slot.

[0026] By adopting the above technical solution, when the clamping block moves toward the direction close to the stress cone, the linkage rod pushes the bottom end of the transition rod toward the direction close to the stress cone, and the top end of the linkage rod swings toward the direction away from the stress cone, thereby pushing the bottom end of the swing rod to move toward the direction away from the stress cone, and then the top end of the swing rod moves toward the direction close to the stress cone, so that the abutment and the outer peripheral wall of the corresponding unit cone are pressed together by interference, so that the middle part of the stress cone axis is in close contact with the cable, so that the stress cone as a whole maintains a stable and tight connection with the cable.

[0027] Preferably, the linkage rod includes a first vertical portion, a second vertical portion and a horizontal portion, the bottom end of the first vertical portion is fixedly connected to the top surface of the clamping block, the top end of the first vertical portion penetrates into the second groove body, the end of the horizontal portion close to the stress cone is connected to the top end of the first vertical portion, the end of the horizontal portion away from the stress cone is connected to and fixed to the bottom end of the second vertical portion, and the top end of the second vertical portion abuts against the bottom end of the transition rod.

[0028] By adopting the above technical solution, the setting of the linkage rod allows the transition rod and the swing rod to have a larger movement space.

[0029] Preferably, the cross section of the abutment member is semicircular, and a surface of the abutment member close to the stress cone is an arc surface.

[0030] By adopting the above technical solution, the scratching of the stress cone by the abutment member is reduced.

[0031] In a second aspect, the method of use provided by the present application comprises the following steps:

[0032] S1. Press the terminal block onto the conductor of the cable;

[0033] S2. Insert the cable with the press-fitted terminal into the slot of the stress cone, with the conductor passing through the first through-hole and the terminal passing through the second through-hole in the first main body;

[0034] S3. Rotate the positioning ring so that the inner circumferential wall of the positioning ring and the outer circumferential wall of the abutting block are in interference fit, the inner circumferential wall of the upper portion of the abutting block and the outer circumferential wall of the unit cone are in interference fit, and the inner circumferential wall of the lower portion of the abutting block and the outer circumferential wall of the metal shielding layer are in interference fit;

[0035] When the abutting block moves toward the direction close to the stress cone, the linkage rod pushes the bottom end of the transition rod toward the direction close to the stress cone, and the top end of the linkage rod swings toward the direction away from the stress cone, thereby pushing the bottom end of the swing rod to move toward the direction away from the stress cone, and then causing the top end of the swing rod to move toward the direction close to the stress cone, so that the abutment piece and the outer peripheral wall of the corresponding unit cone are in interference fit.

[0036] S4. Insert the electrical equipment connection end into the first main body, pass the stud bolt of the stud bolt assembly through the wiring terminal and the electrical equipment connection end, then lock the wiring terminal with the nut of the stud bolt assembly, screw the insulating plug on the other end of the stud bolt, and finally put on the shielding cap to ground the grounding wire.

[0037] By adopting the above technical solution, the cable and the connector can be quickly plugged in and a stable connection can be maintained.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. When inserting the cable, since the stress cone is divided into two parts, there is a gap between the stress cone and the cable, which facilitates the insertion of the cable. The step setting provides automatic positioning of the cable insertion position, and no positioning mark is required. Finally, the positioning ring is rotated to make the tightening block press against the stress cone and the cable, so that the cable and the connector can be quickly plugged in and maintain a stable connection. When the cable needs to be unplugged, the positioning ring is rotated to the tightening block to loosen the stress cone, which is convenient to operate.

[0040] 2. When the abutment block moves toward the direction approaching the stress cone, the linkage rod pushes the bottom end of the transition rod toward the direction approaching the stress cone, and the top end of the linkage rod swings toward the direction away from the stress cone, thereby pushing the bottom end of the swing rod to move toward the direction away from the stress cone, and then the top end of the swing rod moves toward the direction approaching the stress cone, so that the abutment piece and the outer peripheral wall of the corresponding unit cone are pressed together with interference fit, so that the middle part of the stress cone axis is in close contact with the cable, so that the stress cone as a whole maintains a stable and tight connection with the cable.

[0049] Reference Figure 1-5 The quick-plug shielded connector includes a connector body 1, which includes a horizontally arranged first main body portion 11 and a vertically arranged second main body portion 12 below the first main body portion 11. The two ends of the first main body portion 11 are respectively provided with an electrical equipment connection terminal 2 and an insulating plug 3.

[0050] The second main body 12 is provided with an installation groove 121 for installing the stress cone 4, the installation groove 121 is provided with a stress cone 4, the stress cone 4 is provided with a slot 41 for inserting the cable 5, the cable 5 includes a conductor 51, an insulating layer 52, a semi-conductive layer 53, and a metal shielding layer 54 arranged from the inside out, the bottom of the slot 41 is provided with a step 411 corresponding to the conductor 51, the insulating layer 52, the semi-conductive layer 53, and the metal shielding layer 54, the top of the slot 41 is provided with a first through hole 42 for the conductor 51 to pass through, and the top of the insulating layer 52 is connected to the insertion hole 41. The inner top wall of the groove 41 is abutted, and the top of the installation groove 121 is provided with a second through-hole 43 for connecting the first main body part 11 and the second main body part 12. A wiring terminal 6 is provided in the second through-hole 43, and the wiring terminal 6 can be inserted into the first main body part 11 through the second through-hole 43. The size of the first through-hole 42 is sufficient for the wiring terminal 6 to pass through. The electrical equipment connection end 2, the insulating plug 3 and the wiring terminal 6 are fixedly connected by a stud bolt assembly 61; corresponding protrusions 122 are provided on both sides of the second main body part 12, and a grounding hole 123 is provided on the protrusion 122.

[0051] The stress cone 4 includes two symmetrical unit cones 44, which form a whole after being assembled. The two unit cones 44 move in the direction of approaching or moving away from each other. A fixed block 71 is fixedly provided below the second main body 12. Two fixed blocks 71 are symmetrically provided along the radial direction of the second main body 12. A positioning ring 72 is provided between the two fixed blocks 71. The positioning ring 72 is rotatably connected to the fixed block 71. A tightening block 73 is provided in the fixed block 71. The positioning ring 72 can be rotated to the tightening block 73 to tighten the stress cone 4 and the cable 5. The positioning ring 72 can also be rotated to the tightening block 73 to separate from the stress cone 4.

[0052] When inserting the cable 5, since the stress cone 4 is composed of two separate pieces, there is a gap between the stress cone 4 and the cable 5, which facilitates the insertion of the cable 5. The setting of the step 411 provides automatic positioning for the insertion position of the cable 5, and there is no need to make positioning marks. Finally, the positioning ring 72 is rotated to make the tightening block 73 press against the stress cone 4 and the cable 5, so that the cable 5 and the connector can be quickly plugged in and a stable connection is maintained. When the cable 5 needs to be pulled out, the positioning ring 72 is rotated to the tightening block 73 to loosen the stress cone 4, which is convenient to operate.

[0053] A guide block 45 is provided on the top surface of the stress cone 4. The guide block 45 is T-shaped. A guide groove 46 is provided on the top wall of the mounting groove 121. The guide groove 46 is adapted to the shape of the guide block 45. The guide block 45 slides in the guide groove 46, so that the stress cone 4 is located in the second main body 12 and cannot be separated from the joint body 1.

[0054] The longitudinal section of the fixing block 71 is L-shaped. The fixing block 71 is provided with an accommodating groove 711 for the pressing block 73 to slide toward or away from the stress cone 4 and a rotating groove 712 for the positioning ring 72 to rotate.

[0055] The abutting block 73 includes an upper portion 731 abutting against the unit cone 44 and a lower portion 732 abutting against the metal shielding layer 54 of the cable 5 .

[0056] The tightening block 73 is located in the axial middle part of the positioning ring 72, and a contact wedge surface 733 is provided on one side of the tightening block 73 in the width direction. A clearance groove 721 is provided on the positioning ring 72, and a trigger wedge surface 722 that cooperates with the contact wedge surface 733 is provided on one side of the clearance groove 721. The positioning ring 72 is rotated to make the trigger wedge surface 722 push the contact wedge surface 733. When the trigger wedge surface 722 pushes the contact wedge surface 733, the tightening block 73 is pushed toward the direction close to the stress cone 4 until the inner peripheral wall of the positioning ring 72 and the outer peripheral wall of the tightening block 73 are interfered with, the inner peripheral wall of the upper part 731 of the tightening block 73 and the outer peripheral wall of the unit cone 44 are interfered with, and the inner peripheral wall of the lower part 732 of the tightening block 73 and the outer peripheral wall of the metal shielding layer 54 are interfered with.

[0057] After the positioning ring 72 is rotated in the reverse direction, the trigger wedge surface 722 is separated from the contact wedge surface 733 , and the pressing block 73 loses its pressing force on the stress cone 4 and the cable 5 .

[0058] The positioning ring 72 is rotated to make the trigger wedge surface 722 push the contact wedge surface 733. When the trigger wedge surface 722 pushes the contact wedge surface 733, the holding block 73 is pushed toward the stress cone 4 until the inner peripheral wall of the positioning ring 72 and the outer peripheral wall of the holding block 73 are in interference fit, the inner peripheral wall of the upper portion 731 of the holding block 73 and the outer peripheral wall of the unit cone 44 are in interference fit, and the inner peripheral wall of the lower portion 732 of the holding block 73 and the outer peripheral wall of the metal shielding layer 54 are in interference fit, thereby locking the stress cone 4 and the cable 5, improving the connection tightness between the stress cone 4 and the cable 5, and avoiding displacement between the stress cone 4 and the cable 5 to cause stress evacuation;

[0059] After the positioning ring 72 is rotated in the reverse direction, the trigger wedge surface 722 is separated from the contact wedge surface 733, and the pressing block 73 loses its pressing force on the stress cone 4 and the cable 5, making it easier to pull out the cable 5.

[0060] A limiting block 734 is provided on the bottom surface of the clamping block 73, and a limiting groove 735 for the limiting block 734 to slide is provided on the inner bottom wall of the accommodating groove 711, which provides a guide limit for the sliding of the clamping block 73 toward or away from the stress cone 4, and the clamping block 73 cannot be separated from the fixed block 71.

[0061] A tension spring 736 is provided in the accommodating groove 711, one end of the tension spring 736 is fixedly connected to the inner wall of the accommodating groove 711, and the other end of the tension spring 736 is fixedly connected to the clamping block 73. The tension spring 736 applies a force to the clamping block 73 to move the clamping block 73 in a direction away from the stress cone 4. The tension force of the tension spring 736 on the clamping block 73 is less than the friction force caused by the interference fit between the positioning ring 72 and the clamping block 73, the clamping block 73 and the unit cone 44, and the clamping block 73 and the metal shielding layer 54.

[0062] When there is no limitation of the positioning ring 72 , the tension spring 736 pulls the pressing block 73 in a direction away from the stress cone 4 , so that the pressing block 73 is not likely to hinder the insertion of the cable 5 .

[0063] A pressing component 8 is further provided inside the second main body 12 for pressing the middle portion of the stress cone 4 in the axial direction. The pressing component 8 corresponds to the unit cone 44 one by one.

[0064] The tightening assembly 8 includes a linkage rod 81, a transition rod 82 and a swing rod 83. One end of the linkage rod 81 is fixedly connected to the top surface of the tightening block 73. The linkage rod 81 passes through the fixed block 71 and extends into the second main body 12. A first groove 91 for sliding the linkage rod 81 is provided on the fixed block 71. A second groove 92 for sliding the linkage rod 81 is provided inside the second main body 12. A third groove 93 communicating with the second groove 92 is provided in the second main body 12. The transition rod 82 and the swing rod 83 swing in the third groove 93. The transition rod 82 is axially spaced from the center of the transition rod 82. The lower portion of the mounting groove 121 is rotatably connected to the inner wall of the third groove 93 via a first rotating shaft. The middle portion of the swinging rod 83 in the longitudinal direction is rotatably connected to the inner wall of the third groove 93 via a second rotating shaft. The bottom end of the transition rod 82 abuts against the top surface of the linkage rod 81 near the stress cone 4. The top end of the transition rod 82 abuts against the bottom surface of the swinging rod 83 near the stress cone 4. The top surface of the swinging rod 83 near the unit cone 44 is provided with an abutment 84. An opening 94 for the abutment 84 to pass through is formed on the inner wall of the mounting groove 121, and the opening 94 is connected to the third groove 93. The cross-section of the abutment 84 is semicircular, and the surface of the abutment 84 near the stress cone 4 is an arc surface, which reduces the risk of scratching the stress cone 4 caused by the abutment 84.

[0065] The linkage rod 81 includes a first vertical portion 811, a second vertical portion 812, and a horizontal portion 813. The bottom end of the first vertical portion 811 is fixedly connected to the top surface of the abutment block 73, and the top end of the first vertical portion 811 penetrates into the second slot 92. The end of the horizontal portion 813, which is close to the stress cone 4, is connected to the top end of the first vertical portion 811. The end of the horizontal portion 813, which is away from the stress cone 4, is connected to and fixed to the bottom end of the second vertical portion 812. The top end of the second vertical portion 812 abuts the bottom end of the transition rod 82. The configuration of the linkage rod 81 provides greater room for movement for the transition rod 82 and the swing rod 83.

[0066] A compression spring 831 is provided at the bottom end of the swing arm 83, one end of the compression spring 831 is fixedly connected to the inner wall of the third groove body 93, and the other end of the compression spring 831 is fixedly connected to the abutment 84. The compression spring 831 applies a force to the bottom end of the swing arm 83 to move the bottom end of the swing arm 83 toward the direction close to the unit cone 44, so that the abutment 84 does not hinder the cable 5 from being inserted into the slot 41 during the process of inserting the cable 5 into the slot 41.

[0067] When the clamping block 73 moves toward the direction approaching the stress cone 4, the linkage rod 81 pushes the bottom end of the transition rod 82 toward the direction approaching the stress cone 4, and the top end of the linkage rod 81 swings toward the direction away from the stress cone 4, thereby pushing the bottom end of the swing rod 83 to move toward the direction away from the stress cone 4, and then the top end of the swing rod 83 moves toward the direction approaching the stress cone 4, so that the abutment 84 is pressed against the outer peripheral wall of the corresponding unit cone 44 with interference fit, so that the middle part of the axis of the stress cone 4 is in close contact with the cable 5, so that the stress cone 4 as a whole maintains a stable and tight connection with the cable 5.

[0068] In a second aspect, the present application also discloses a method of use, comprising the following steps:

[0069] S1. Press the terminal 6 onto the conductor 51 of the cable 5;

[0070] S2. Insert the cable 5 with the terminal 6 pressed into the slot 41 of the stress cone 4. The conductor 51 passes through the first through-hole 42 and the terminal 6 passes through the second through-hole 43 and is located in the first main body 11.
