Description

Technical Field

[0001] The invention relates to the technical field related to cable connection, and in particular to a reserved connector for a bypass cable of a distribution network. Background Art

[0002] The bypass cable of the distribution network is an important tool in the uninterrupted power supply operation of the distribution network. It is mainly used to form a temporary power supply system to ensure that customers do not have power outages. At the same time, the equipment under maintenance needs to be isolated from the power grid to achieve the purpose of live equipment replacement. The bypass cable has the advantages of easy use, high safety, and excellent insulation performance. It is not affected by terrain conditions and can be widely used in mountain paths, farmlands and other terrains. In the bypass operation of the distribution network, the bypass cable is used in conjunction with equipment such as bypass load switches to achieve the maintenance and inspection of the equipment and ensure the stable operation of the power system. The bypass cable connector is a high-voltage cable connector that can be quickly connected and separated.

[0003] Existing bypass cable connectors, such as the Chinese patent with publication number CN115939802A, disclose an intelligent bypass cable connector and a method of using the same, including a connector body, an inner core, and a control system; the inner core includes conductive rods arranged on the left and right, and an insulating layer insulated and wrapped around the outside of the conductive rods; the left and right parts of the connector body are both provided with locking devices; each set of locking devices includes a fixedly connected inner ring, an axially movable outer ring, and an electrified locking device located in the inner ring and limiting the moving position of the outer ring; the electrified locking device includes a swing rod rotating in the middle, an electromagnet at one end of the swing rod that is energized by the main control module and adsorbs the swing rod, and a pin shaft radially arranged and installed at the other end of the swing rod; the pin shaft passes through the inner ring and acts on the outer ring; the present invention effectively prevents plugging and unplugging under power, avoids electric shock accidents caused by misoperation of operators, and realizes real-time monitoring, analysis, and evaluation of the operating status of the intelligent bypass cable connector and the bypass system, which is safer and more reliable.

DETAILED DESCRIPTION

[0031] The following is combined with Figures 1 to 10 This application is described in further detail.

[0032] An embodiment of the present application discloses a reserved connector for a bypass cable of a distribution network. The present application positions and clamps the end of the bypass cable, and performs a stripping operation to expose the cable core, and performs a reserved sealing on the position of the cable core. When docking is required later, the cable core is exposed for quick crimping and docking.

[0033] Reference Figures 1 to 3 As shown, a distribution network bypass cable reserved connector disclosed in this embodiment includes a reserved sleeve 1, a rotating part 2, a positioning component 3, a connecting tube 4, a locking component 5, a stripping component 6, a sealing sleeve 7, a docking sleeve 8, an extrusion component 9, a crimping component 10, and a docking part 11. The reserved sleeve 1 is a fixed base, and the rotating part 2 is sleeved on the outside of the reserved sleeve 1 by threaded fitting. The interior of the reserved sleeve 1 is uniformly slidably provided with a positioning component 3 along its circumference, and the reserved sleeve 1 and the positioning component 3 are used for extrusion fitting. The outer end of the connecting tube 4 is connected to the reserved sleeve 1 by rotation fitting, and the position between the reserved sleeve 1 and the connecting tube 4 is locked by the locking component 5. Temporary locking is performed, and the stripping component 6 is horizontally inserted into the built-in groove provided in the connecting tube 4. The rotating connecting tube 4 drives the embedded stripping component 6 to strip the end of the bypass cable. The sealing sleeve 7 is horizontally sleeved on the inner end position of the connecting tube 4, and the docking sleeve 8 is located between the sealing sleeves 7. An extrusion component 9 is arranged at the middle upper end of the docking sleeve 8, and crimping components 10 are symmetrically arranged at the left and right ends of the interior of the docking sleeve 8. A docking piece 11 is installed in the middle of the docking sleeve 8. The docking piece 11 is made of conductive material, and the extrusion component 9 and the crimping component 10 are used for extrusion cooperation. The crimping component 10 after extrusion performs crimping connection on the stripped cable core.

[0034] In the actual operation process, the reserved sleeve 1 is sleeved on the end of the bypass cable, and the positioning component 3 is squeezed toward the center by rotating the rotating part 2 to clamp and position the surface of the bypass cable. At the same time, the spirally moving rotating part 2 squeezes the locking component 5 to unlock the position between the reserved sleeve 1 and the connecting tube 4 (the stripping component 6 is inserted into the cable skin after being squeezed), and then the connecting tube 4 is rotated, and the synchronously rotating stripping component 6 cuts the surface of the cable circumferentially, and then the sealing sleeve 7 is pulled out in the opposite direction of the bypass cable. The cut cylindrical skin is synchronously pulled out under the interception of the stripping component 6, so as to expose the cable core, and then the sealing sleeve 7 is reinserted into the connecting tube 4 to perform a reserved protective seal on the cable core position. When the bypass cable needs to be connected later, the sealing sleeve 7 is removed at this time, and the exposed cable core is inserted into the crimping component 10. The crimping component 10 is crimped and connected to the cable core by twisting the squeezing component 9, and the crimping component 10 after crimping is connected to the docking piece 11, so as to achieve the purpose of connection.

[0035] Reference Figure 4 As shown, in order to clamp and position the reserved sleeve 1 and the bypass cable, the present application achieves the purpose of clamping and positioning through the cooperation between the rotating part 2 and the positioning assembly 3. The rotating part 2 includes a rotating cylinder 21, which is sleeved on the outside of the reserved sleeve 1 by threaded cooperation. The inner wall of the rotating cylinder 21 is evenly provided with extrusion heads 22 along its circumference.

[0036] Reference Figure 4 , Figure 5 As shown, the positioning assembly 3 includes an arc-shaped member 31, which is slidably arranged inside the reserved sleeve 1. An extrusion block 32 is installed on the outer surface of the arc-shaped member 31, and the inclined surface of the extrusion block 32 and the inclined surface of the extrusion head 22 are used for extrusion cooperation. A strip-shaped positioning layer is evenly installed on the inner wall of the arc-shaped member 31. The strip-shaped positioning layer is an inclined structure. After it is tightly attached to the cable surface, the possibility of falling off is reduced.

[0037] In actual operation, the rotating cylinder 21 is rotated to make it rotate in a spiral manner, and the extrusion block 32 is squeezed by the translational extrusion head 22 so that the arc-shaped member 31 as a whole moves toward the center direction, thereby clamping and positioning the cable surface.

[0038] Reference Figure 5 , Figure 6As shown, before the peeling component 6 is inserted into the epidermis, the connecting tube 4 and the reserved sleeve 1 need to be locked to prevent the connecting tube 4 from rotating in advance, thereby driving the peeling component 6 to cut in advance, and then causing premature cutting before falling to the accurate cutting position. The present application solves the above problem through a locking component 5, and its specific structure is as follows: the locking component 5 includes a pushing block 51 and a clamping rod 52. The pushing block 51 is horizontally slidably arranged in a sliding groove opened on the surface of the reserved sleeve 1, and a ball is arranged on the outer end face of the pushing block 51. The arrangement of the ball reduces the friction force, and the ball fits with the inner end face of the rotating tube 21. The clamping rod 52 is horizontally slidably arranged in a movable groove opened on the surface of the connecting tube 4, and the clamping rod 52 and the movable groove are elastically connected, and the elastic connection always maintains the tendency of the clamping rod 52 to push outward; the outer end part of the clamping rod 52 is temporarily clamped in the sliding groove, and the inner end of the clamping rod 52 is provided with a slope to reduce the extrusion resistance.

[0039] During the actual locking process, when the locking rod 52 is not squeezed, the outer end portion of the locking rod 52 is temporarily clamped in the sliding groove under the action of elasticity, so that the position between the connecting cylinder 4 and the reserved sleeve 1 is locked. When unlocking is required later, it is only necessary to rotate the rotating cylinder 21 to make it move spirally to squeeze and push the pushing block 51, and then completely push the locking rod 52 out of the sliding groove (the pushing block 51 has not entered the movable groove) to unlock it.

[0040] Reference Figure 4 , Figure 6 As shown, in order to facilitate peeling and subsequent docking, the present application further improves the peeling component 6, which includes an embedded block 61, a clamping groove 62, a knife seat 63, a peeling knife 64, and a docking groove 65. The embedded block 61 is slidably arranged in the built-in groove up and down, and a clamping groove 62 is provided at one end of the embedded block 61 close to the axial position of the connecting tube 4. The knife seat 63 is tightly attached to one end of the embedded block 61, and the knife seat 63 is slidably arranged in the built-in groove up and down. A peeling knife 64 is temporarily installed on the knife seat 63, and the knife seat in the initial position The outer half of the piece 63 is located in the built-in groove, and the inner half of the knife seat piece 63 in the initial position is clamped in the docking groove 65 opened on the side wall of the sealing sleeve 7; the inner side wall of the embedded block 61 is provided with a sliding block, and the sliding block is slidably arranged in the limiting groove opened on the side wall of the built-in groove. When the knife seat piece 63 completely enters the docking groove 65, the stripping knife 64 has completely cut into the cable skin, and the sliding block has also slid to the maximum track. The embedded block 61 is squeezed by the clamping rod 52 and the sliding block is limited in the limiting groove and is in a position locked state.

[0041] In the actual operation process, the clamping rod 52 is squeezed to move inward, thereby squeezing the embedded block 61 to approach the axial position of the connecting tube 4. At this time, the knife seat 63 matched with the embedded block 61 drives the stripping knife 64 to penetrate into the cable skin. When the knife seat 63 completely enters the docking groove 65, the stripping knife 64 has completely cut into the cable skin. With the rotation of the unlocked connecting tube 4, the synchronously rotating stripping knife 64 performs circumferential movement to cut in an annular shape, and then the sealing sleeve 7 is pulled out in the opposite direction of the bypass cable (due to the knife seat 6 3 is not stuck between the built-in groove and the docking groove 65, and the knife holder 63 has completely entered the docking groove 65, at this time, the position between the sealing sleeve 7 and the connecting tube 4 has been unlocked, and the sealing sleeve 7 can be pulled out separately), the cut surface waste is also taken out from the outside of the cable core, and then the surface waste is taken out, and the knife holder 63 and the stripping knife 64 are taken out (the removed knife holder 63 and the stripping knife 64 can be temporarily installed in the built-in groove of other connecting tubes 4 and can be recycled), and the sealing sleeve 7 is reinserted to provide sealed protection for the exposed cable core.

[0042] Reference Figure 5 , Figure 7 As shown, a sealing cover 12 is embedded in the inner end opening position of the sealing sleeve 7, and a finger groove is provided on the end face of the sealing cover 12, through which the sealing cover 12 can be opened, and embedded blocks are symmetrically arranged on the left and right ends of the docking sleeve 8, which play the role of embedded plug-in with the connecting tube 4.

[0043] Reference Figures 7 to 9 As shown, when the bypass cable needs to be connected, the present application connects the bypass cable through the extrusion component 9, the crimping component 10 and the connection tube 4 of the reserved structure, so as to effectively connect the bypass cable. Its specific structure is that the extrusion component 9 includes a connector 91, a threaded member 92, and an extrusion member 93. The connector 91 is connected and installed in the middle of the upper end of the docking sleeve 8. The threaded member 92 is threadedly connected to the inside of the connector 91. A cross groove is provided at the upper end of the threaded member 92. The lower end of the threaded member 92 is connected to the extrusion member 93 in a rotationally matched connection, which ensures that the extrusion member 93 is in a linearly descending state while the threaded member 92 spirally descends. The extrusion member 93 is arranged inside the connector 91 in an up and down sliding manner.

[0044] Reference Figures 7 to 10As shown, the crimping assembly 10 includes a sliding sleeve 101, a crimping block 102, a guide rail 103, a sliding column 104, and a clamping block 105. A movable block is installed on the outer wall of the sliding sleeve 101. The movable block is horizontally slidably arranged in a horizontal groove opened by the docking sleeve 8, and the movable block and the horizontal groove are elastically connected. The interior of the sliding sleeve 101 is symmetrically slidably arranged with the crimping block 102, the guide rail 103 is opened at the side wall position of the docking sleeve 8, the sliding column 104 is installed at the side wall position of the crimping block 102, and the crimping block 102 is Made of conductive material, the sliding column 104 is slidably set in the guide track 103 of the inclined structure. Taking the movement trajectory of the crimping block 102 on the left as an example, as the sliding sleeve 101 moves to the left, the crimping blocks 102 arranged up and down gradually move closer under the guidance of the guide track 103, thereby forming a subsequent crimping connection, and the clamping block 105 is slidably set up and down in the vertical groove opened in the docking sleeve 8. The clamping block 105 and the chamfered end face of the sliding sleeve 101 are used for extrusion cooperation, and the position between the clamping block 105 and the clamping groove 62 corresponds.

[0045] In the actual operation process, the sealing sleeve 7 is pulled out from the connecting tube 4, and the docking sleeve 8 is inserted into the connecting tube 4 to replace the original position of the sealing sleeve 7. At this time, the exposed cable core enters between the upper and lower arranged clamping blocks 105, and is inserted into the cross groove with the help of a tool to twist, so that the threaded member 92 descends in a spiral manner, and the extruding member 93 descends in a straight line, thereby squeezing the sliding sleeves 101 arranged on the left and right to move in the opposite direction (the moving sliding sleeves 101 will also squeeze the clamping blocks 105 to extend outward). During its movement, the cable core is inserted into the cross groove with the help of a tool to twist, so that the threaded member 92 descends in a spiral manner, and the extruding member 93 descends in a straight line, thereby squeezing the sliding sleeves 101 arranged on the left and right to move in the opposite direction (the moving sliding sleeves 101 will also squeeze the clamping blocks 105 to extend outward). Under the action of the guide rail 103, the upper and lower crimping blocks 102 move toward each other. When the left and right sliding sleeves 101 move in the opposite direction to the maximum value, the spacing between the upper and lower crimping blocks 102 is the shortest. At this time, the cable core is crimped and connected by the upper and lower crimping blocks 102, and the crimping blocks 102 contact with the docking pieces 11, thereby completing the connection between the left and right cable cores after crimping. At this time, the outwardly extending clamping block 105 will also be clamped into the clamping groove 62, so that the position between the connecting tube 4 and the docking sleeve 8 is locked.

[0046] Working principle:

[0047] Step 1: The reserved sleeve 1 is sleeved on the end of the bypass cable, and the positioning component 3 is squeezed by rotating the rotating member 2 to clamp and position the surface of the bypass cable. At the same time, the spirally moving rotating member 2 squeezes the locking component 5 to unlock the position between the reserved sleeve 1 and the connecting tube 4;

[0048] Step 2: Rotate the connecting cylinder 4 to drive the synchronously rotating stripping assembly 6 to perform circumferential cutting on the cable skin, thereby cutting off the skin at the cable end (this part is the skin waste);

[0049] Step 3: Pull out the sealing sleeve 7 from the connecting tube 4, take out the surface waste, remove the knife seat 63 and the peeling knife 64, and then reinsert the sealing sleeve 7 into the connecting tube 4 to perform a reserved protective seal on the cable core position;

[0050] Step 4: When the bypass cable needs to be connected, remove the sealing sleeve 7, insert the docking sleeve 8 into the connecting tube 4 to replace the original position of the sealing sleeve 7, insert the exposed cable core into the crimping assembly 10, and twist the extrusion assembly 9 to crimp the cable core. After crimping, the crimping assembly 10 is connected to the docking piece 11, and the connection is completed.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
