[0001] The invention relates to the technical field of round cables, in particular to a round cable harness with a flat connector reinforcement structure. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings.

[0003] The traditional way to connect round cables is to remove the outer sheath of the cable and the harness connector and connect through the exposed wire core. However, this method requires personnel to carry corresponding tools to peel off the outer sheath, and the peeled length of the outer sheath must be accurately measured. In addition, the exposed wire core is prone to leakage. The overall operation time is long and it is not convenient for personnel to operate, which needs to be improved.

[0007] Preferably, blades are fixed to the bottom ends of the first cable groove and the second cable groove of the lower shell, and the two blades are close to the corresponding connection ends respectively.

[0008] Preferably, a plurality of the first needles are provided, the plurality of first needles are distributed around the center of the corresponding connection end, and the plurality of first needles are located at the outer edge of the corresponding connection end, and the plurality of first needles respectively pierce the outer skin of the corresponding cable and the circular wiring harness head.

[0009] Preferably, the first cable groove and the second cable groove of the lower shell are both provided with sliding grooves at the bottom ends, and a slider is fixed to the bottom end of the connecting end. The slider slides in the corresponding sliding grooves, and the two sliding grooves are respectively distributed along the length directions of the first cable groove and the second cable groove.

[0010] Preferably, an injection port is provided at the top of the upper shell, a cavity is provided inside the upper shell, discharge holes are provided on both sides of the bottom of the upper shell, and the discharge holes and the injection port are both connected to the inside of the cavity.

[0015] Preferably, the length of the cable and the round harness head extending into one end of the connection assembly is longer than two-thirds of the length of the connection assembly.

[0016] Technical effects and advantages of the present invention: 1. In the actual operation of the present invention, the upper shell and the lower shell are rotated to open each other, so that the ends of the cable and the round wiring harness head can be installed in the first cable groove and the second cable groove. Inside, by rotating and closing the upper shell and the lower shell, the upper shell and the lower shell can clamp and limit the cable and the round wiring harness head, thereby fixing the position of the cable and the round wiring harness head, and there is no need for additional work such as stripping and measuring the outer skin, thereby reducing the installation time.

[0017] 2. Place the ends of the cable and the round wiring harness head into the first cable trough and the second cable trough, and push the ends of the cable and the round wiring harness head to fit with the corresponding connecting ends. At this time, multiple first needles will pierce the outer skin of the corresponding cable and the round wiring harness head to connect the cable and the round wiring harness head with the corresponding connecting ends, so as to avoid separation of the cable, the round wiring harness head and the corresponding connecting ends during the installation process.

[0018] 3. When the ends of the cables and round wiring harness heads are pushed into the corresponding first cable trough and second cable trough, the bottom ends of the outer skins of the cables and round wiring harness heads will come into contact with the blades, and the blades will cut the bottom ends of the outer skins, thereby enlarging the gap between the outer skins and the wire cores, making it easier for the ends of the wire cores to detach from the outer skins, exposing the outer skins to the ends of the wire cores.

[0019] 4. After the ends of the cables and round harness heads are fixed, the user can rotate the upper shell to close the upper and lower shells. During the rotation of the upper shell, the conductive puncture needle at the bottom of the second conductive sheet will first pierce the outer skin. As the closure is completed, the conductive puncture needle will completely pierce the wire core of the cables and round harness heads.

[0020] 5. After the conductive puncture needle is inserted into the outer skin, the outer skin and the wire core will rotate as the upper shell rotates. Since the blade cuts the bottom of the outer skin, the outer skin and the wire core will rotate to produce a torsional displacement, so that the end of the wire core is exposed from the outer skin, so that the end of the wire core and the connection end will not be blocked by the outer skin, avoiding interference.

[0021] 6. Furthermore, after the conductive puncture needle completely penetrates into the wire core, the cable and the circular wiring harness head can be connected through the second conductive sheet, thereby enhancing the connection strength between the cable and the circular wiring harness head. The penetration of the conductive puncture needle can also improve the fixing strength of the cable and the circular wiring harness head, thereby avoiding deflection of the cable, the circular wiring harness head and the connection assembly during use.

[0022] 7. When the cable and the round wiring harness head are connected and the upper shell and the lower shell are closed, insulating resin can be injected into the cavity through the injection port to wrap the cable and the outside of the round wiring harness head and fill the internal gap to reduce air residue. As the injection is carried out, a part of the insulating resin will be input into the space between the spring and the blocking block along the pressure relief port to fill the area between the two. At the same time, the pressure generated when the insulating resin is injected can be reduced to prevent the pressure from separating the wire core and the connection end.

DETAILED DESCRIPTION

[0031] The present invention provides Figure 1 to Figure 7 A round cable harness with a flat connector reinforcement structure is shown, comprising a cable 1 and a round harness head 3; Flat connector: a connecting component 2, wherein the connecting component 2 is used to connect the cable 1 and the round wiring harness head 3; Before connecting, include the following preparatory steps: S1. Clean the outer sides of the cable 1 and the circular wiring harness head 3 to prevent the impurities adhering to the outer sides of the cable 1 and the circular wiring harness head 3 from affecting the connection and conductive effect during connection.

[0032] S2. Cut the ends of the connecting lines of the cable 1 end and the circular wiring harness head 3 flatly, and make the cuts smooth and complete, so as to prevent the outer skins of the cable 1 end and the circular wiring harness head 3 from wrapping around the ends of the wire cores, so as to facilitate the subsequent connection between the cable 1 end and the wire cores of the circular wiring harness head 3.

[0033] S3, fixing the cable 1 and the circular wiring harness head 3 after being cut flatly through the connecting component 2, so that the cable 1 and the circular wiring harness head 3 are electrically connected; S4. Insulating resin is injected into the connecting component 2, and the insulating resin is covered on the connection between the cable 1 and the circular wiring harness head 3. The insulating resin is used to wrap the connection between the cable 1 and the circular wiring harness head 3 to avoid leakage. At the same time, it can enhance the stability and structural strength of the overall structure and reduce looseness between the cable 1, the circular wiring harness head 3 and the connecting component 2.

[0034] It is important to prevent the insulating resin from entering between the cable 1 and the round harness head 3 .

[0035] Among them, the connecting component 2 includes an upper shell 4 and a lower shell 5, one side of the upper shell 4 and the lower shell 5 are hinged to each other, and the first cable groove 9 and the second cable groove 10 are opened on the opposite sides of the upper shell 4 and the lower shell 5. The first ends of the cable 1 and the circular wiring harness head 3 are respectively clamped in the first cable groove 9 and the second cable groove 10, and the length of the cable 1 and the circular wiring harness head 3 extending into one end of the connecting component 2 is longer than two-thirds of the length of the connecting component 2.

[0036] Avoid the cable 1 and the round harness head 3 extending into the connection component 2 for a short length, which may cause the connection failure or the connection end 13 to fail to contact the wire core inside the cable 1 and the round harness head 3.

[0037] In the actual operation of the present invention, the upper shell 4 and the lower shell 5 are rotated to open each other, so that the ends of the cable 1 and the circular wiring harness head 3 can be installed in the first cable groove 9 and the second cable groove 10. Inside, by rotating and closing the upper shell 4 and the lower shell 5, the upper shell 4 and the lower shell 5 can clamp and limit the cable 1 and the circular wiring harness head 3, thereby fixing the position of the cable 1 and the circular wiring harness head 3.

[0038] A connecting block 7 is fixed to the other side of the upper shell 4 and the lower shell 5 . The two connecting blocks 7 correspond to each other up and down, and a fixing screw 8 is provided between the two connecting blocks 7 .

[0039] Specifically, in actual use, the upper shell 4 and the lower shell 5 can be closed by aligning the connecting blocks 7 on one side of the upper shell 4 and the lower shell 5 and tightening the fixing screws 8 to complete the fixing function, which is convenient for installation and also convenient for later disassembly.

[0040] The first cable groove 9 and the second cable groove 10 of the lower shell 5 are fixed with a blocking block 11 at one end away from each other, and the first conductive sheet is fixed to the opposite end of the two blocking blocks 11. A spring 12 is fixed to the opposite side of the two first conductive sheets, and a connecting end 13 is fixed to the opposite end of the two springs 12. The two first conductive sheets are connected by a conductive block, and a first needle 15 is arranged on the opposite side of the two connecting ends 13. The first needle 15 can pierce the corresponding end of the cable 1 and the round wiring harness head 3.

[0041] A second conductive sheet 18 is arranged between the first cable groove 9 and the second cable groove 10 of the upper shell 4. A conductive puncture needle 19 is arranged at the bottom end of the second conductive sheet 18 at the first cable groove 9 and the second cable groove 10. The conductive puncture needle 19 pierces the corresponding cable 1 and the circular wiring harness head 3 respectively.

[0042] There are multiple first needles 15, which are distributed around the center of the corresponding connecting end 13 and located at the outer edge of the corresponding connecting end 13. The multiple first needles 15 respectively penetrate into the outer skin of the corresponding cable 1 and the round wiring harness head 3, and grooves 22 are provided on opposite sides of the two connecting ends 13.

[0043] When the cable 1 and the conductor inside the round harness head 3 can be inserted into the groove 22 , the insulating resin is prevented from entering the contact area between the conductor and the connection end 13 .

[0044] In the actual operation of the present invention, the ends of the cable 1 and the circular wiring harness head 3 are placed inside the first cable groove 9 and the second cable groove 10, and the ends of the cable 1 and the circular wiring harness head 3 are pushed to fit with the corresponding connecting ends 13. At this time, multiple first needles 15 will penetrate into the outer skin of the corresponding cable 1 and the circular wiring harness head 3, so that the cable 1 and the circular wiring harness head 3 are connected to the corresponding connecting ends 13, thereby avoiding separation of the cable 1, the circular wiring harness head 3 and the corresponding connecting ends 13 during the installation process.

[0045] When the cable 1, the wire core in the circular harness head 3 and the connecting end 13 are fitted and connected, through the connection of the conductive block, when power is turned on, the current can pass through the cable 1, the conductive block and the circular harness head 3 in sequence to complete the current transmission task.

[0046] Furthermore, the elastic force of the spring 12 can make the connecting end 13 always fit the end of the wire core to avoid a gap between the two.

[0047] Blades 14 are fixed to the bottom ends of the first cable groove 9 and the second cable groove 10 of the lower shell 5, and the two blades 14 are respectively close to the corresponding connection ends 13. In the actual operation of the present invention, when the ends of the cable 1 and the circular wiring harness head 3 are pushed into the corresponding first cable groove 9 and the second cable groove 10, the bottom ends of the outer skins of the cable 1 and the circular wiring harness head 3 will contact the blades 14, and the blades 14 will cut the bottom ends of the outer skins, thereby enlarging the gap between the outer skins and the wire cores, making it easier for the ends of the wire cores to detach from the outer skins, exposing the outer skins to the ends of the wire cores.

[0048] Furthermore, after the ends of the cable 1 and the circular wiring harness head 3 are fixed, the user can rotate the upper shell 4 to close the upper shell 4 and the lower shell 5. During the rotation of the upper shell 4, the conductive puncture needle 19 at the bottom of the second conductive sheet 18 will first penetrate into the outer skin. As the closure is completed, the conductive puncture needle 19 will completely penetrate into the wire core of the cable 1 and the circular wiring harness head 3.

[0049] After the conductive puncture needle 19 first penetrates the outer skin, as the upper shell 4 rotates, it will drive the outer skin and the wire core to rotate. Since the blade 14 cuts the bottom end of the outer skin, the outer skin is relatively loose at this time. Through the rotation between the outer skin and the wire core, a torsional displacement can be generated between the outer skin and the wire core, so that the end of the wire core is exposed from the outer skin, so that the end of the wire core and the connection end 13 will not be blocked by the outer skin, avoiding interference.

[0050] Furthermore, after the conductive puncture needle 19 is completely inserted into the wire core, the cable 1 and the circular wiring harness head 3 can be connected through the second conductive sheet 18, thereby enhancing the connection strength between the cable 1 and the circular wiring harness head 3. The insertion of the conductive puncture needle 19 can also improve the fixing strength of the cable 1 and the circular wiring harness head 3, thereby avoiding deflection of the cable 1, the circular wiring harness head 3 and the connecting component 2 during use.

[0051] The second conductive sheet 18 is configured to be M-shaped, and insulating pads 21 are fixed on both sides of the inner bending part of the M-shaped structure. The side cross-section of the insulating pad 21 is configured to be triangular, and the tip of the insulating pad 21 is configured to face downward. The insulating pads 21 are distributed along the length direction of the second conductive sheet 18 .

[0052] In the actual operation of the present invention, when the upper shell 4 and the lower shell 5 are closed, the insulating pad 21 at the bottom bend of the second conductive sheet 18 will be limited on both sides of the corresponding cable 1 and the circular wiring harness head 3, and inserted into the gap between the cable 1, the circular wiring harness head 3 and the corresponding first cable groove 9 and the second cable groove 10 to prevent the gap from causing the cable 1 and the circular wiring harness head 3 to rotate.

[0053] A slide groove 17 is provided at the bottom end of the first cable groove 9 and the second cable groove 10 of the lower shell 5, and a slider is fixed to the bottom end of the connecting end 13. The slider slides in the corresponding slide groove 17, and the two slide grooves 17 are respectively distributed along the length direction of the first cable groove 9 and the second cable groove 10.

[0054] An injection port 6 is provided at the top of the upper shell 4 , a cavity is provided inside the upper shell 4 , discharge holes 20 are provided on both sides of the bottom of the upper shell 4 , and the discharge holes 20 and the injection port 6 are both connected to the inside of the cavity.

[0055] In the actual operation of the present invention, when the cable 1 and the circular wiring harness head 3 are connected and the upper shell 4 and the lower shell 5 are closed, insulating resin can be injected into the cavity through the injection port 6. The insulating resin will pass through the cavity and be injected into the first cable groove 9 and the second cable groove 10, wrapping the outside of the cable 1 and the circular wiring harness head 3 and filling the internal gap to reduce air residue and improve the insulation and anti-corrosion and moisture-proof effects.

[0056] And as the insulating resin is filled, the cut of the outer skin after being cut by the blade 14 can be filled to prevent the outer skin from being too loose, and the blade 14 can be covered to prevent the blade 14 from rubbing against the outer skin and the inside of the wire core again during use, causing damage.

[0057] It should be noted that both the upper shell 4 and the lower shell 5 are made of insulating materials to avoid leakage. At the same time, after the insulating resin fills the inside of the cavity, the weight of the upper shell 4 can be increased, thereby improving the structural strength.

[0058] A pressure relief port 16 is provided on one side of the two connecting ends 13. The two pressure relief ports 16 penetrate the other side of the corresponding connecting end 13 at the same time. The pressure relief port 16 is tilted downward toward one side of the corresponding spring 12. The pressure relief port 16 is lower than the first needle 15 at the highest point.

[0059] During the injection process of the insulating resin, a portion of the insulating resin will be input into the space between the spring 12 and the blocking block 11 along the pressure relief port 16 to fill the area between the two. At the same time, the pressure generated during the injection of the insulating resin can be reduced to prevent the pressure from causing the wire core and the connecting end 13 to separate.
