Description

Technical Field

[0001] This utility model belongs to the field of cable crimping technology, and in particular relates to a multi-core cable clamping device and a cable crimping machine. Background Technology

[0002] Riveted terminals or connectors are placed at the ends of the core wires of the cable to facilitate subsequent connection or assembly of the cable.

[0003] Wire crimping terminals are completed using a terminal crimping machine. Specifically, the terminal crimping machine is equipped with an upper crimping die, a lower crimping die, and a terminal strip pushing mechanism. The terminal strip pushing mechanism pushes the terminal strip onto the lower crimping die, places the core wire on the lower crimping die, and then the upper and lower crimping dies cooperate to complete the terminal crimping, while simultaneously cutting the terminal off the strip.

[0004] For example, Chinese patent document CN119542868A discloses a four-core wire crimping device. This device addresses the technical problem of low yield rates in four-core wire crimping where the core wires protrude from their ends at short distances. Specifically, it addresses the issue of short core wires and their connection to terminals. After folding the upper core wire, it causes a springback at a certain angle, affecting subsequent stripping and crimping operations. The stripping mechanism includes a cutter assembly for cutting the outer insulation and a stripping drive connected to the cutter assembly to move the cut outer insulation away from the wire harness. For stripping the outer insulation of the core wire, the cutter assembly first partially or completely cuts the outer insulation, and then the stripping drive moves the cutter assembly to detach the cut outer insulation from the core wire, thus achieving the stripping operation. The crimping mechanism is arranged side-by-side with the stripping mechanism and includes a crimping seat for crimping terminals. The crimping mechanism is existing technology; it moves the terminal strip and, through pressing... The crimping of the connector towards the crimping seat enables the sequential crimping of the terminals of the core wires after the outer insulation has been stripped. The bending mechanism is arranged opposite to the stripping mechanism or the crimping mechanism, including a clamping assembly for holding the core wire and a bending assembly for holding the wire harness body and bending the wire harness body relative to the core wire. The clamping assembly is used to hold the core wire so that the core wire is always in a horizontal state, while the bending assembly is used to hold the wire harness body and then bend the wire harness body relative to the core wire. This structural arrangement, in which the core wire remains stationary while the wire harness body is bent relative to it, is beneficial for the subsequent processing of the core wires and ensures the continuity of processing.

[0005] In the aforementioned patent literature, to avoid interference from other core wires to the core wires of the crimp terminal, a bending mechanism is used to clamp the wire harness body and then bend the wire harness body relative to the core wires. This structural design, where the core wires remain stationary while the wire harness body bends relative to them, facilitates subsequent core wire processing and ensures processing continuity. The bending assembly includes a swing table for clamping the cable, a wire clamping seat mounted on the swing table, and a bending drive component rotatably connected to the swing table. The end of the swing table near the stop bar is rotatably connected, and the bending drive component is connected to the end of the swing table away from the stop bar. By rotatably connecting the end of the swing table near the stop bar, the wire harness body follows the angle change of the swing table as the swing table rotates. Because the core wires are pressed by the clamping arm, the core wires can remain horizontal. However, this clamping and bending method not only presents technical problems such as complex structure and operation. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-core cable clamping device, which solves the technical problem in the prior art that when one or two core wires of a multi-core cable are crimped to a terminal, the bending of the core wire by the clamping part is required to participate in the crimping, which is complicated in terms of structure and operation.

[0007] To achieve the above objectives, this utility model provides a multi-core cable clamping device, including a parallel clamp, clamping claws, and a support block. The parallel clamp includes two sliders, and the two clamping claws are respectively disposed on the two sliders of the parallel clamp. Each of the two clamping claws has a clamping groove on its opposite side. One end of each clamping claw extends into a clamping portion. The support block is disposed on the parallel clamp, and one end of the support block extends upward into a protrusion. The protrusion has a clearance hole, and the top side of the protrusion has a support portion located between the two clamping portions.

[0008] Furthermore, the support portion has guide surfaces on both sides near the end of the vent hole, and the two guide surfaces intersect to form a guide portion.

[0009] Furthermore, the clearance hole extends to the top side of the protrusion, and the clearance hole has an inclined guide surface near the support.

[0010] Furthermore, the guiding surface is also a bifurcated guiding part.

[0011] Furthermore, one of the grippers has a clearance slit on its bottom side, and the other gripper has a base plate on its bottom side, the base plate extending to the clearance slit; the base plate is used to support the clamped cable.

[0012] Furthermore, the parallel clamp also includes a body and a cylinder; the top side of the body is provided with a sliding groove, and the two sliders are slidably disposed in the sliding groove. The upper ends of the sliders are provided with limiting steps on both sides, and the top side of the body is also provided with two limiting blocks, which extend to the top side of the limiting steps; the opposite ends of the two sliders are also provided with extension plates, and the extension plates are provided with actuating grooves; the bottom side of the sliding groove is also provided with a through hole, and the cylinder is disposed on the bottom side of the parallel clamp. The piston rod of the cylinder passes through the through hole and extends into the sliding groove. The upper end of the piston rod is provided with a pin, which extends into the actuating groove.

[0013] Furthermore, the limiting block is also provided with an installation groove, which is perpendicular to the sliding groove, and the support block is disposed in the installation groove.

[0014] Furthermore, the mounting groove is provided with limiting grooves on both sides, and the support block is provided with limiting parts on both sides, with the limiting parts being limited within the limiting grooves.

[0015] Furthermore, the support block has an abutment extending downward from one end away from the support portion, and the abutment is located on one side of the parallel clamp; the abutment is connected to an inductive switch; the parallel clamp is provided with a limiting member, which is used to limit the abutment, and a compression spring is provided between the abutment and the parallel clamp or the limiting member.

[0016] The multi-core wire clamping device provided in this embodiment of the utility model has at least the following technical effects: This multi-core cable clamping device, when clamping cables requiring crimping terminals, places the main body of the cable between two clamping jaws. The core wire requiring crimping, along with its adjacent core wire at the same horizontal level, is positioned on both sides of the support portion. The remaining core wires extend into the clearance holes and are confined to the bottom side of the protrusion. This separates the core wires not involved in crimping from those requiring crimping, preventing interference. The parallel clamp then drives the two clamping jaws to move relative to each other, causing the main body of the two jaws to clamp the main body of the cable, while the two clamping portions respectively clamp the core wires located on both sides of the support portion. This multi-core cable clamping device utilizes the support block structure to achieve core wire separation, and its structure and operation are simple. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of the cable crimping machine of this utility model, please refer to... Figure 1 The cable crimping machine of this embodiment is used for crimping terminals onto cables with multiple core wires. Specifically, the cable crimping machine includes a multi-core cable clamping device 10, a crimping machine 20, and an upper crimping die 30 and a lower crimping die 40 disposed on the crimping machine 20. The multi-core cable clamping device 20 clamps the cable to be crimped, and the end of the core wire extends between the upper crimping die 30 and the lower crimping die 40. The crimping machine 20 drives the upper crimping die 30 to descend and cooperate with the lower crimping die 40, thereby crimping the terminal onto the end of the core wire.

[0029] Specifically, refer to Figures 2 to 4 The multi-core cable clamping device 10 includes a parallel clamp 100, clamping claws 200, and a support block 300. The parallel clamp 100 includes two sliders 110, and two clamping claws 200 are respectively disposed on the two sliders 110. Each clamping claw 200 has a clamping groove 201 on its opposite side, which clamps the cable when it is clamped. One end of each clamping claw 200 extends into a clamping portion 210. The support block 300 is disposed on the parallel clamp 100, and one end of the support block 300 extends upward into a protrusion 310. The protrusion 310 has a clearance hole 311, and a support portion 320 is located between the two clamping portions 210 on its top side.

[0030] In this embodiment, the multi-core cable clamping device 10 clamps a cable requiring crimping terminals. The main body of the cable is located between the two clamping jaws 200. The core wire requiring crimping terminals, along with adjacent core wires at the same horizontal level, are respectively positioned on both sides of the support portion 320. The remaining core wires extend into the clearance holes 311 and are confined to the bottom side of the protrusions 310. This separates the core wires not involved in crimping terminals from those requiring crimping terminals, preventing interference. The parallel clamp 100 then drives the two clamping jaws 200 to move relative to each other, causing the clamping grooves 201 of the two clamping jaws 200 to clamp the main body of the cable, while the two clamping portions 210 respectively clamp the core wires located on both sides of the support portion 320. The separation of core wires is achieved using the structure of the support block 300, resulting in a simple structure and operation method.

[0031] Furthermore, refer to Figure 4The support portion 320 has guide surfaces 321 on both sides near the end of the clearance hole 311, and the two guide surfaces 321 intersect to form a guide portion 322. When the cable is extended to the clamping position formed by the support portion 320 and the clamping portion 210, the guide cores are separated by the guide portion 322 and distributed on both sides of the support portion 320.

[0032] Furthermore, refer to Figure 4 The clearance hole 311 extends to the top side of the protrusion 310, and the clearance hole 311 is provided with an inclined guide surface 312 near the support. The core wire that does not participate in the crimping of the terminal is guided into the clearance hole 311 by the guide surface 312.

[0033] Furthermore, refer to Figure 4 The guide surface 312 is also the bifurcated guide part 313. The guide surface 312 is used to separate the core wires that extend into the clearance hole 311, which facilitates subsequent processing.

[0034] Furthermore, refer to Figure 2 and Figure 3 One gripper 200 has a clearance slit 202 on its bottom side, and the other gripper 200 has a base plate 203 on its bottom side, which extends to the clearance slit 202; the base plate 203 is used to support the clamped cable. This facilitates the gripper 200 clamping the cable.

[0035] Furthermore, refer to Figure 5 and Figure 6 The parallel clamp 100 also includes a body 120 and a cylinder 130; the top side of the body 120 is provided with a slide groove 121, and two sliders 110 are slidably disposed in the slide groove 121. The upper ends of the sliders 110 are provided with limiting steps 111 on both sides. The top side of the body 120 is also provided with two limiting blocks 140, which extend to the top side of the limiting steps 111; the opposite ends of the two sliders 110 are also provided with extension plates 112, which are provided with actuating grooves 113; the bottom side of the slide groove 121 is also provided with a through hole, and the cylinder 130 is disposed on the bottom side of the body 120. The piston rod of the cylinder 130 passes through the through hole and extends into the slide groove 121. The upper end of the piston rod is provided with a pin 131, which extends into the actuating groove 113. In this embodiment, the cylinder 130 drives the pin 131 to rise and fall, and the pin 131 slides within the actuation groove 113, enabling the two sliders 110 to slide within the sliding groove 121. This allows the gripper 200 to clamp and release the cable.

[0036] Furthermore, refer to Figure 5 and Figure 6 The limiting block 140 is also provided with an installation groove 141, which is perpendicular to the slide groove 121, and the support block 300 is located in the installation groove 141.

[0037] Furthermore, refer to Figure 4 middle Figure 6The mounting groove 141 is provided with limiting grooves on both sides, and the support block 300 is provided with limiting parts 301 on both sides, which are limited within the limiting grooves. This ensures that the support block 300 is limited within the mounting groove 141.

[0038] Furthermore, refer to Figure 3 The support block 300 has a downwardly extending abutment portion 330 at one end away from the support portion 320, located on one side of the parallel clamp 100. A sensor switch 340 is connected to the abutment portion 330. A limiting member 150 is provided on the parallel clamp 100 to limit the abutment portion 330. A compression spring (not shown in the figures) is provided between the abutment portion 330 and the parallel clamp 100 or the limiting member 150. In this embodiment, the support block 300 can slide, and the sensor switch 340 can detect whether the support block 300 has moved. Specifically, when the cable is moved by an external force, it will pull the support block 300 to move, thereby detecting the displacement, preventing cable misalignment, and ensuring the quality of the core wire and terminal crimping.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
