[0002] A single-core cable is a conductor generally used to transmit electric energy, signals or data. The structure of the cable is usually composed of a conductive core, an insulating layer, a metal shielding layer and a sheath (105).

[0058] like Figures 1 to 8 As shown, a cable quick splicing device of the present invention includes a connector 1, which is provided with an insulating outer shell layer 11, a shielding shell layer 12 and a conductive inner shell layer 13. The insulating outer shell layer 11, the shielding shell layer 12 and the conductive inner shell layer 13 are arranged in sequence from the outside to the inside.

[0059] Specifically, the insulating outer shell layer 11 is a plastic sheath 105 such as polyvinyl chloride PVC, polyethylene PE, or a metal sheath 105 such as steel belt armor, steel wire armor, etc., which protects the connection between the A cable 101 and the B cable 102 from the invasion of external impurities, moisture, mechanical damage and chemical corrosion.

[0060] The shielding shell 12 includes copper wire weaving, copper wire winding, aluminum wire aluminum alloy wire weaving, copper tape, aluminum foil, aluminum steel plastic tape, steel tape and other wrapping or longitudinal wrapping. The shielding shell 12 isolates the electromagnetic field at the connection between the A cable 101 and the B cable 102 from the external electromagnetic field, limiting the electric field and electromagnetic interference.

[0061] The conductive inner shell 13 is made of a highly conductive metal material, such as copper or aluminum, to facilitate the A cable 101 and the B cable 102 to transmit electrical energy or signals.

[0062] The insulating outer shell layer 11 is provided with a first connecting tube 111 and a second connecting tube 112, the A cable 101 is plugged into the first connecting tube 111, and the B cable 102 is plugged into the second connecting tube 112. The first connecting tube 111 and the second connecting tube 112 are both provided with a crimping portion 113, and the sheaths 105 of the A cable 101 and the B cable 102 are both crimped with the crimping portion 113.

[0063] Specifically, a waterproof ring is provided on the inner side of the crimping portion 113, and a deformation groove is provided on the waterproof ring along the axial direction. When the crimping portion 113 is crimped with the A cable 101 and the B cable 102, the waterproof ring is deformed through the deformation groove, so that the waterproof ring is tightly attached to the surface of the sheath 105 of the A cable 101 and the B cable 102, so that the crimping portion 113 and the surface of the sheath 105 of the A cable 101 and the B cable 102 are sealed.

[0064] The shielding shell 12 is provided with a shielding layer conductor 121 , and the metal shielding layers 104 of the A cable 101 and the B cable 102 are both connected to the shielding layer conductor 121 .

[0065] The conductive inner shell 13 is provided with a cell conductive connector 131 , and the conductive cores 103 of the A cable 101 and the B cable 102 are both connected to the cell conductive connector 131 .

[0066] By crimping the sheaths 105 of the A cable 101 and the B cable 102 with the crimping portion 113, connecting the metal shielding layers 104 of the A cable 101 and the B cable 102 with the shielding layer conductor 121, and connecting the conductive cores 103 of the A cable 101 and the B cable 102 with the conductive core conductor 131, the connector 1 is wrapped around the connection between the A cable 101 and the B cable 102, thereby achieving splicing of the A cable 101 and the B cable 102, and connecting the metal shielding layers 104 of the A cable and the B cable, without having to spend a long time to restore the insulation layer at the connection between the two cables A cable and B cable.

[0067] How to quickly splice cables:

[0068] The A cable 101 and the B cable 102 are carried by the workbench 2 .

[0069] The workbench 2 is provided with a clamping and positioning mechanism 3, a conveying mechanism 4, a cutting machine, a visual recognition mechanism, a stripper, a crimping pliers and a main control system.

[0070] A telescopic fixing fixture 21 is provided in the middle of the workbench 2 , and the telescopic fixing fixture 21 is used to carry and fix the connector 1 .

[0071] The clamping and positioning mechanism 3 is disposed above the telescopic fixing fixture 21 and is used to clamp and fix the A cable 101 and the B cable 102 .

[0072] There are at least two conveying mechanisms 4 , which are respectively disposed at the edge of the workbench 2 and are used to convey the A cable 101 and the B cable 102 to the clamping and positioning mechanism 3 .

[0073] The cutting machine is fixed on both sides of the workbench 2 and is used to cut the A cable 101 and the B cable 102 so that the cut cross sections of the A cable 101 and the B cable 102 are flat.

[0074] The visual recognition mechanism is used to obtain images of the cut sections of the A cable 101 and the B cable 102 and feed them back to the main control system. Specifically, the visual recognition mechanism includes a camera and a displacement driver for driving the camera to move. The displacement driver is a conventional linear drive module or a conventional cylinder.

[0075] The displacement driver is arranged along the length direction of the workbench 2, and the camera is fixed to one end of the displacement driver and moves with the movement of the displacement driver. The displacement driver facilitates the camera to move, so that the visual recognition mechanism can obtain the images of the cut sections of the A cable 101 and the B cable 102.

[0076] The stripper is used to strip the A cable 101 and the B cable 102 so that the conductive core 103 and the metal shielding layer 104 of the A cable 101 and the B cable 102 are exposed.

[0077] The crimping pliers are used to crimp the A cable 101 and the connector 1 , and the B cable 102 and the connector 1 .

[0078] The main control system is used to analyze the images of the cut cross-sections of cable A 101 and cable B 102. The clamping and positioning mechanism 3, the conveying mechanism 4, the cutting machine, the visual recognition mechanism, the stripper and the crimping pliers are all electrically connected to the main control system, so that the main control system can control the clamping and positioning mechanism 3, the conveying mechanism 4, the cutting machine, the visual recognition mechanism, the stripper and the crimping pliers.

[0079] The following steps are included:

[0080] A. The A cable 101 and the B cable 102 are transported to the workbench 2 by the transport device, and the A cable 101 and the B cable 102 are clamped and positioned on the workbench 2 by the clamping and positioning mechanism 3;

[0081] B. Cutting the A cable 101 and the B cable 102 respectively by a cutting machine so that the cut cross sections of the A cable 101 and the B cable 102 are flat, and obtaining images of the cut cross sections of the A cable 101 and the B cable 102 by a visual recognition mechanism and feeding them back to the main control system;

[0082] C. The main control system analyzes the distance D1 between the surface of the conductive core 103 of the A cable 101 and the B cable 102 and the outer surface of the sheath 105, and the distance D2 between the surface of the metal shielding layer 104 and the outer surface of the sheath 105, respectively, based on the images of the cut cross sections of the A cable 101 and the B cable 102, and uses a stripper to strip the A cable 101 and the B cable 102 at a depth of a distance D1 to form a first connection groove 106 and at a depth of a distance D2 to form a second connection groove 107, so that the conductive core 103 of the A cable 101 and the B cable 102 is exposed through the first connection groove 106 and the metal shielding layer 104 is exposed through the second connection groove 107;

[0083] D. Release the A cable 101 and the B cable 102 through the clamping and positioning mechanism 3, lift the connector 1 by the telescopic fixing fixture 21, align the first connecting tube 111 with the A cable 101, align the second connecting tube 112 with the B cable 102, insert the A cable 101 into the first connecting tube 111, and insert the B cable 102 into the second connecting tube 112 through the conveying device, so that the conductive cores 103 of the A cable 101 and the B cable 102 are both connected to the core conductive connector 131, and the metal shielding layers 104 of the A cable 101 and the B cable 102 are both connected to the shielding layer conductive connector 121;

[0084] E. Use crimping pliers to crimp the crimping portions 113 of the first connecting tube 111 and the second connecting tube 112 to the sheath 105 of the A cable 101 and the sheath 105 of the B cable 102 , respectively, so that the A cable 101 and the B cable 102 are spliced ​​through the connector 1 .

[0085] like Figure 1 and Figure 2 As shown, the first connecting tube 111 and the second connecting tube 112 of this embodiment are staggered.

[0086] The connector 1 includes a crimping member 14 , and the crimping member 14 includes a first crimping member 141 and a second crimping member 142 .

[0087] The cell conductive member 131 is provided with a connecting hole 132 which penetrates the first connecting tube 111 and the second connecting tube 112 .

[0088] The first crimping piece 141 is provided with a core-wrapped portion 1411 for wrapping the conductive core 103 of the A cable 101 or the B cable 102 and a limiting portion 1412 for being clamped on one side of the connecting hole 132. The first crimping piece 141 is sleeved on the end of the A cable 101 or the B cable 102, and is crimped with the conductive core 103 of the A cable 101 or the B cable 102 through the core-wrapped portion 1411, and is crimped with the sheath 105 of the A cable 101 or the B cable 102 through the limiting portion 1412. The A cable 101 and the B cable 102 are respectively passed through the core-wrapped portion 1411 and extended out of the connecting hole 132. The limiting portion 1412 is clamped outside the connecting hole 132, so that the A cable 101 and the B cable 102 are both connected to the battery core conductive piece 131 through the first crimping piece 141.

[0089] The second crimping piece 142 is crimped with the core-wrapped portion 1411, so that the first crimping piece 141 is limited to the connection hole 132, so that the A cable 101 and the B cable 102 are fixed to the cell conductor 131 through the first crimping piece 141. On the other hand, the friction and wear between the A cable 101 or the B cable 102 and the cell conductor 131 are reduced.

[0090] Preferably, the connecting hole 132 and the core-wrapped portion 1411 can be configured to be elliptical, square, or polygonal to prevent the core-wrapped portion 1411 from rotating relative to the connecting hole 132 .

[0091] An insulating protective cover 143 is disposed on a side of the second crimping member 142 away from the connecting hole 132 . The insulating protective cover 143 is disposed on the second crimping member 142 to prevent the portion of the core-wrapped portion 1411 extending out of the connecting hole 132 from being exposed.

[0092] An insulating sheet 1413 is provided at one end of the limiting portion 1412 away from the core-wrapped portion 1411 , and the insulating sheet 1413 prevents the first crimping member 141 from being connected to the metal shielding layer 104 of the A cable 101 or the B cable 102 .

[0093] The surface of the core-wrapped portion 1411 is provided with a receiving groove 1414, the width of which is greater than the width of the second crimping member 142, a deforming ring 1415 is provided in the receiving groove 1414, and a deforming sheet 1416 is provided at the opening of the receiving groove 1414. When the second crimping member 142 is crimped with the core-wrapped portion 1411, the second crimping member 142 applies pressure to the deforming sheet 1416 and the deforming ring 1415, so that the deforming ring 1415 is deformed and protrudes from the receiving groove 1414, and at the same time, the deforming sheet 1416 is lifted, so that the deforming sheet 1416 is bent, so that the deformed ring and the deforming sheet 1416 cooperate to restrict the second crimping member 142, and prevent the second crimping member 142 from separating from the core-wrapped portion 1411.

[0094] Specifically, the deformation ring 1415 is a soft metal, such as gold, silver, lead, tin, aluminum, zinc, etc. The deformation ring 1415 has a relatively low hardness and good ductility.

[0095] The deformation sheet 1416 is a metal sheet, such as a stainless steel sheet, a copper alloy sheet or an aluminum alloy sheet, so that the detection sheet 62 has high strength and rigidity, and can be significantly bent and deformed when subjected to pressure while maintaining good stability.

[0096] like Figure 2 and Figure 3 As shown, the connector 1 of this embodiment includes a conductive member 15 .

[0097] The conductive member 15 is crimped with the metal shielding layer 104 of the A cable 101 and the metal shielding layer 104 of the B cable 102 through the second connection groove 107. The conductive member 15 fills the second connection groove 107, so that the metal shielding layer 104 of the A cable 101 and the metal shielding layer 104 of the B cable 102 are connected to the shielding layer conductive member 121.

[0098] The conductive member 15 includes a first insulator 151 , a conductor 152 , and a second insulator 153 . The first insulator 151 and the second insulator 153 are clamped on both sides of the conductor 152 .

[0099] The first insulator 151 and the second insulator 153 respectively contact the second connection groove 107 , so that the airtightness between the conductive member 15 and the second connection groove 107 is improved.

[0100] Preferably, the first insulator 151 and the second insulator 153 are epoxy resin, polyurethane, silicone rubber or polyimide, and the first insulator 151 and the second insulator 153 increase the sealing between the first conductive member 15 and the second conductive member 15 and the A cable 101 or the B cable 102 .

[0101] like Figure 3 As shown, a pressing and deforming portion 154 is provided at one end of the conductor 152 of this embodiment. The pressing and deforming portion 154 includes a deformation cavity 155 and deformation corners 156 connected to two ends of the deformation cavity 155 .

[0102] When the conductive member 15 is crimped with the metal shielding layer 104 of cable A 101 and the metal shielding layer 104 of cable B 102, the crimping pliers apply pressure to the conductor 152, and the deformed corners 156 come into contact with and bend out of shape, and the deformed corners 156 are tightly attached to the metal shielding layer 104 of cable A 101 and the metal shielding layer 104 of cable B 102, and the pressed deformed portion 154 is crimped to the metal shielding layer 104 of cable A 101 and the metal shielding layer 104 of cable B 102, thereby increasing the contact area between the conductor 152 and the metal shielding layer 104 of cable A 101 and the metal shielding layer 104 of cable B 102.

[0103] The first insulator 151 and the second insulator 153 are both provided with a yielding deformation portion 157 corresponding to the pressed deformation portion 154. The yielding deformation portion 157 provides a deformation space for the pressed deformation portion 154, thereby preventing the second connection groove 107 from being deformed when the conductive member 15 is crimped with the metal shielding layer 104 of the A cable 101 and the metal shielding layer 104 of the B cable 102.

[0104] like Figure 1 As shown, the first connecting tube 111 of this embodiment is provided with a first opening 16 corresponding to the connecting hole 132, and the second connecting tube 112 is provided with a second opening 17 corresponding to the connecting hole 132. The first opening 16 and the second opening 17 facilitate the crimping piece 14 and the crimping piece 14 to be crimped with the conductive core 103 of the A cable 101 and to be located on the side of the core conductive piece 131 away from the insulating layer of the A cable 101, and the crimping piece 14 and the conductive core 103 of the B cable 102 to be crimped with the conductive core 103 of the B cable 102 and to be located on the side of the core conductive piece 131 away from the insulating layer of the B cable 102.

[0105] A sealing member 18 is disposed at each of the first opening 16 and the second opening 17 . The sealing member 18 is threadedly connected to the first opening 16 and the second opening 17 , respectively.

[0106] The seal 18 is provided with a first injection hole 181 and a first exhaust hole 182. The first injection hole 181 and the first exhaust hole 182 cooperate to facilitate the injection of sealing material into the first opening 16 and the second opening 17. The sealing material can be one of polyurethane grouting liquid, cable trench foam fireproof plugging material, polymer moisture-proof plugging agent or foaming fireproof sealant.

[0107] like Figure 4 As shown, the crimping portion 113 of this embodiment is provided with a crimping detection mechanism 6 for detecting the crimping effect between the crimping portion 113 and the sheaths 105 of the A cable 101 and the B cable 102 .

[0108] The crimping detection mechanism 6 includes a collapse piece 61 and a detection piece 62 disposed on one side of the sheath 105 of the crimping portion 113 facing the A cable 101 and the B cable 102 . The detection piece 62 is connected to the crimping portion 113 via the collapse piece 61 , thereby connecting the detection piece 62 to the crimping portion 113 .

[0109] An observation port 114 is provided through the crimping portion 113 corresponding to the detection piece 62 . The end of the detection piece 62 is disposed in the observation port 114 . The end of the detection piece 62 can be conveniently viewed through the observation port 114 .

[0110] The detection piece 62 is provided with a first supporting point 621 and a second supporting point 622. Specifically, the detection piece 62 is in a wave shape or a W shape, and this embodiment takes the detection piece 62 in a W shape as an example.

[0111] When the crimping pliers crimp the crimping portion 113 and the sheaths 105 of the A cable 101 and the B cable 102 , the detection piece 62 contacts the crimping portion 113 through the first supporting point 621 and contacts the sheath 105 of the A cable 101 or the B cable 102 through the second supporting point 622 .

[0112] During the crimping process, the crimping portion 113 applies pressure to the collapse piece 61 and the detection piece 62 at the same time. The collapse piece 61 collapses under the pressure, and the detection piece 62 is deformed under the pressure with the second support point 622 as a fulcrum, so that the end of the detection piece 62 is tilted and extends out of the observation port 114; the height to which the end of the detection piece 62 is tilted and extends out of the observation port 114 can be checked to determine the effect of crimping the crimping portion 113 with the sheath 105 of the A cable 101 and the B cable 102.

[0113] By checking the height of the end of the detection piece 62 that protrudes out of the observation port 114, the effect of the crimping between the crimping portion 113 and the sheath 105 of the A cable 101 and the B cable 102 can be intuitively judged, thereby ensuring that the crimping portion 113 and the sheath 105 of the A cable 101 and the B cable 102 are firmly connected and reducing damage to the crimping portion 113 and the sheath 105 of the A cable 101 and the B cable 102 during the crimping process.

[0114] Specifically, the detection sheet 62 is a metal sheet, such as a stainless steel sheet, a copper alloy sheet or an aluminum alloy sheet, so that the detection sheet 62 has high strength and rigidity, can bend and deform significantly when subjected to pressure, and maintain good stability.

[0115] A scale is provided at the end of the detection piece 62 . By checking the scale at the end of the detection piece 62 , the effect of crimping between the crimping portion 113 and the sheaths 105 of the A cable 101 and the B cable 102 can be judged more clearly and intuitively.

[0116] like Figure 5As shown, the connector 1 of this embodiment is wrapped with a glue injection shell 19 on the outside, and the glue injection shell 19 wraps the crimping point between the sheath 105 of the A cable 101 and the B cable 102 and the crimping part 113. The glue injection shell 19 is penetrated by a second glue injection hole 191 and a second exhaust hole 192. Through the cooperation of the second glue injection hole 191 and the second exhaust hole 192, it is convenient to inject sealing material into the glue injection shell 19, so that the crimping point between the sheath 105 of the A cable 101 and the B cable 102 and the crimping part 113 is sealed. The sealing material can be one of polyurethane grouting liquid, cable trench foam fireproof sealing material, polymer moisture-proof sealing agent or foaming fireproof sealant.

[0117] like Figure 7 As shown, the clamping and positioning mechanism 3 of this embodiment includes a clamping member 31 and a clamping driver 32 for driving the clamping member 31 to open and close. The clamping driver 32 is a clamping manipulator or a finger cylinder.

[0118] The clamping member 31 includes a first clamping portion 311 , a limiting member 312 and a second clamping portion 313 which are sequentially arranged. The first clamping portion 311 and the second clamping portion 313 are both sequentially provided with a first peeling groove 314 and a second peeling groove 315 in a direction away from the limiting member 312 .

[0119] Specifically, the first clamping part 311 and the second clamping part 313 are both multi-finger clamps, and intervals are arranged between each multi-finger clamp. The first interval arranged in sequence along the direction away from the limiting part 312 is the first stripping groove 314, and the second interval is the second stripping groove 315.

[0120] When in use, the A cable 101 is fixed to the clamping member 31 through the first clamping portion 311. The B cable 102 is fixed to the clamping member 31 through the second clamping portion 313. The limiter 312 limits the length of the A cable 101 and the B cable 102 inserted into the clamping member 31.

[0121] The cutting machine cuts the A cable 101 and the B cable 102 through the first stripping groove 314 close to the side of the limiting member 312 .

[0122] The stripper strips the A cable 101 and the B cable 102 through the first stripping groove 314 to form a first connection groove 106 , and strips the A cable 101 and the B cable 102 through the second stripping groove 315 to form a second connection groove 107 .

[0123] The first stripping groove 314 and the second stripping groove 315 cooperate to make the position positioning of cutting, stripping and slotting of the A cable 101 and the B cable 102 more accurate.

[0124] In actual use, a detection groove 3121 capable of observing the cross-section of cable A 101 and cable B 102 is provided inside the limit member 312. After the first clamping portion 311 and the second clamping portion 313 release the cut parts of cable A 101 and cable B 102, the visual recognition mechanism obtains the cut cross-section image of cable A 101 and cable B 102 through the detection groove 3121.

[0125] like Figure 2 and Figure 8 As shown, the position limiting member 312 of this embodiment is provided with a current measuring mechanism 5, and the current measuring mechanism 5 is electrically connected to the main control system. The current measuring mechanism 5 is a current measuring instrument.

[0126] The current measuring mechanism 5 is provided with a first detection end 51 and a second detection end 52. The first detection end 51 is respectively connected to the conductive core 103 and the metal shielding layer 104 of the A cable 101 or the B cable 102, and the second detection end 52 is connected to the cutter of the barker.

[0127] Specifically, the first detection end 51 is a detection disk, on which are provided contact points connected to the conductive core 103 and the metal shielding layer 104 of the A cable 101 or the B cable 102, and the second detection end 52 is a detection clip, which is connected to the cutter of the peeling machine through the detection clip.

[0128] Method for stripping the A cable 101 and the B cable 102 using a stripper:

[0129] C1. When the stripper strips the A cable 101 and the B cable 102 at a distance D1 to form the first connection groove 106, the current measuring mechanism 5 monitors whether there is current between the conductive core 103 of the A cable 101 or the B cable 102 and the cutter of the stripper.

[0130] C2. When there is current between the conductive core 103 of cable A 101 or cable B 102 and the cutter of the stripper, the stripper stops feeding the cutter, thereby controlling the depth of the first connecting groove 106 to avoid surface damage to the conductive core 103 of cable A 101 or cable B 102.

[0131] C3. When the stripper strips the A cable 101 and the B cable 102 at a distance D2 to form the second connection groove 107, the current measuring mechanism 5 monitors whether there is current between the metal shielding layer 104 of the A cable 101 or the B cable 102 and the cutter of the stripper.

[0132] C4. When there is current between the metal shielding layer 104 of cable A 101 or cable B 102 and the cutter of the stripper, the stripper stops feeding the cutter, thereby controlling the depth of the second connecting groove 107 and avoiding surface damage to the metal shielding layer 104 of cable A 101 or cable B 102.

[0133] like Figure 6 As shown, the conveying mechanism 4 of this embodiment includes a fixed conveying wheel group, a sliding conveying wheel group, a conveying wheel driver and a sliding driver.

[0134] The fixed conveying wheel set is rotatably arranged on the workbench 2, the sliding conveying wheel set is slidably arranged with the workbench 2, the sliding driver drives the sliding conveying wheel set to slide close to or away from the fixed conveying wheel set, and the conveying wheel driver drives the sliding conveying wheel set to rotate.

[0135] When in use, the sliding conveying wheel group is driven by the sliding driver to slide close to the fixed conveying wheel group, so that the A cable 101 or the B cable 102 is clamped in the conveying mechanism 4, and the conveying wheel driver drives the sliding conveying wheel group to rotate, and the A cable 101 or the B cable 102 is frictionally connected with the sliding conveying wheel group and the fixed conveying wheel group, so that the conveying mechanism 4 conveys the A cable 101 or the B cable 102.

[0136] A cable is also provided, comprising an A cable 101, a B cable 102 and a connecting device, wherein the A cable 101 and the B cable 102 are connected by the connecting device, and the connecting device is the above-mentioned cable quick splicing device.
