Description

Technical Field

[0001] This utility model relates to the field of piercing terminal machine technology, and in particular to a high-efficiency and precision piercing terminal machine. Background Technology

[0002] The piercing terminal crimping machine is mainly used to connect wires and terminals. Its working principle is that the pressure device drives the punch to move downward. The punch presses the terminal, so that the piercing needle on the terminal can pierce the insulation of the wire, so that the internal metal wire can make close contact with the terminal. At the same time, the structural design of the terminal itself and the pressure applied by the machine will make the terminal firmly wrap the wire part, thereby realizing the electrical connection between the wire and the terminal. Moreover, the connection has good mechanical stability and conductivity.

[0003] Patent CN213782449U discloses a ribbon cable piercing terminal crimping machine, relating to the field of computer component technology. Its technical solution mainly includes a frame with a horizontally arranged guide rail. A sliding seat that slides along the length of the guide rail is also provided on the frame. The upper surface of the sliding seat has a placement groove for mounting piercing terminals. A crimping block located above the placement groove is also slidably mounted on the frame for crimping the piercing terminals. A drive device is also installed on the frame to drive the crimping block to move up and down. This application has the effect of improving the crimping efficiency of ribbon cable piercing terminals.

[0004] However, the aforementioned cable piercing terminal crimping machine still has the following shortcomings:

[0005] The above-mentioned device requires frequent disassembly and assembly of several bolts to adjust the spacing between a set of first stops and a set of second stops in order to limit the piercing terminals of various lengths and the ribbon cables of various widths. The process is cumbersome and reduces the adjustment efficiency. In view of this, we propose a high-efficiency and precision piercing terminal insertion machine. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] A high-efficiency and precision terminal piercing and breaking machine, see Figures 1 to 3 It includes a base 1, a bracket 2 fixed on the surface of the base 1, a limit switch body 3 on the surface of the bracket 2, a drive cylinder 4 on the top of the bracket 2, a punch 5 connected to the movable end of the drive cylinder 4, a slide rail assembly 6 in front of the bracket 2, and a limit component 7 attached to the outside of the slide rail assembly 6.

[0025] The limiting component 7 includes a sliding seat 701, which is movably engaged with the outside of the slide rail component 6. A set of limiting grooves 702 are symmetrically formed on the inner top of the sliding seat 701, and a set of sliding grooves 703 are symmetrically formed at the bottom of the limiting grooves 702. A positive and negative screw 704 passes through the sliding groove 703. A handle 705 is fixedly connected to the front end of the positive and negative screw 704. A set of threaded blocks 706 are symmetrically fitted on the surface of the positive and negative screw 704, and a set of limiting rods 707 are symmetrically fixed to the top of the threaded blocks 706. The limiting grooves 702 and the sliding grooves... The 703 are connected to each other. The top of the limiting rod 707 is flush with the top of the limiting groove 702. The threaded block 706 is matched and engaged inside the sliding groove 703. A guide groove 708 is opened on the inner side of the end of the limiting rod 707 away from the threaded block 706. A cable body 709 is sandwiched between a set of limiting rods 707. A piercing terminal body 710 is attached to the surface of the cable body 709. Furthermore, the piercing terminal body 710 is engaged between a set of guide grooves 708 on the same side. The top of the piercing terminal body 710 is higher than the top of the guide groove 708. This invention effectively drives the positive and negative screws 704 to rotate by rotating the handle 705, thereby causing a set of threaded blocks 706 fitted on the surface of the positive and negative screws 704 to move away from or closer to each other, thus adjusting the spacing between a set of limiting rods 707. This facilitates quick adaptation and limiting of ribbon cable bodies 709 of different widths. After the ribbon cable body 709 is engaged, the piercing terminal body 710 can be effectively and securely attached to the top end of the ribbon cable body 709 through the guide groove 708, improving the accuracy of subsequent connections. This limiting component 7 can simultaneously limit a set of ribbon cable bodies 709 and piercing terminal bodies 710, improving the efficiency of subsequent crimping.

[0026] It is worth noting that the slide rail assembly 6 includes a slide rail body 601, which is fixed to the surface of the base 1. A slot 602 is provided on the inner side of the front end of the slide rail body 601. A locking plate 603 is matched and locked inside the slot 602. A limiting plate 604 is fixedly connected to the front end of the locking plate 603. The limiting plate 604 forms a locking structure with the slide rail body 601 through the locking plate 603, the slot 602, and the sliding seat 701. The sliding seat 701 is matched and locked to the outside of the slide rail body 601. A set of bolts 605 are inserted into the inner side of the top of the slide rail body 601. Furthermore, the slide rail body 601 forms a detachable structure with the locking plate 603 through the bolts 605. The top of the bolts 605 is flush with the top of the slide rail body 601. In this utility model, the slide rail body 601 is used to horizontally guide the sliding seat 701, so that the sliding seat 701 can be moved backward and accurately fit into the limit switch body 3 to realize the opening of the drive cylinder 4. The setting of the limit plate 604 prevents the sliding seat 701 from slipping off the slide rail body 601, improving the safety of use. When the limit component 7 is damaged, the clamping plate 603 and the limit plate 604 can be removed from the slide rail body 601 by removing the bolt 605, so that the limit component 7 can be removed for repair and replacement.

[0027] Working principle: Rotating the handle 705 drives the positive and negative screws 704 to rotate, causing a set of threaded blocks 706 on the surface of the positive and negative screws 704 to move away from or closer to each other. This adjusts the spacing between a set of limit rods 707, allowing for quick adaptation to limit the width of the ribbon cable body 709. After the ribbon cable body 709 is engaged, the piercing terminal body 710 is securely attached to one end of the top of the ribbon cable body 709 via the guide groove 708. Then, the sliding seat 701 is moved backward to precisely align with the limit switch body 3, opening the drive cylinder 4. The drive cylinder 4 then moves the punch 5 downward, piercing the terminal body 710. The downward pressure causes the piercing needles on the piercing terminal body 710 to pierce the insulation of the ribbon cable body 709, making the metal wire inside the ribbon cable body 709 come into close contact with the piercing terminal body 710. Then, the sliding seat 701 is moved forward, and the crimped ribbon cable body 709 and the piercing terminal body 710 can be removed. The limiting component 7 can simultaneously limit a set of ribbon cable bodies 709 and piercing terminal bodies 710, improving crimping efficiency. If the limiting component 7 is damaged in the future, the clamping plate 603 and the limiting plate 604 can be removed from the slide rail body 601 by disassembling the bolt 605, making it convenient to remove the limiting component 7 for repair and replacement.
