Description

Technical Field

[0001] This utility model relates to the field of connector terminal technology, and in particular to an automatic crimping and positioning device for wire connector terminals. Background Technology

[0002] To connect electronic devices to circuits, methods such as soldering and connector terminal connection are usually used. Compared with soldering, connector terminal connection only requires a standardized operation of crimping the terminal and then inserting it into the connector housing, which greatly reduces the manual skill requirements. At the same time, terminal connectors can fix multiple wires together and avoid wires from being messy and tangled.

[0003] When using connector terminals, ensure that the terminal surface is clean to prevent dust from affecting the terminal's performance. Then, determine the terminal insertion direction according to the markings on the terminal housing. Gently push the crimped terminal into the housing guide groove, aligning the positioning structure of the plug and socket, and gently push it in until it is fully fitted. To prevent the terminal from becoming loose after installation and causing poor contact, the terminal will be firmly locked after crimping and insertion.

[0004] In order to prevent the terminals from becoming loose and causing poor contact after installation, the terminals are firmly locked after crimping. However, in scenarios that require frequent disassembly, emergency repairs, or limited space, the terminals and wires are crimped once. When disassembling, the wires need to be cut, and when reusing, the wires need to be stripped and new terminals crimped again. The old terminals are discarded directly, which increases costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic crimping and positioning device for wire connector terminals, which aims to improve the problem of difficulty in disassembling terminals after they are firmly crimped.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic crimping and positioning device for wire connector terminals includes a first connector, a first fixing block fixedly connected inside the first connector, a surrounding block fixedly connected to the outer wall of the first fixing block, a toothed clamp fixedly connected to one end of the surrounding block, a first sliding rod slidably connected to one end of the toothed clamp, a first pull rod installed at one end of the first sliding rod, a first limiting plate fixedly connected to the outer wall of the first sliding rod, a first spring installed on the outer wall of the first sliding rod, and a crimping assembly provided at one end of the first connector.

[0007] The above technical solution involves fixing the first fixing block to the first joint, thereby fixing the surrounding block. The toothed clip, which is fixed to the surrounding block, extends out of the surrounding block, allowing the protruding part of the toothed clip to rebound due to its resilience. Pulling the first pull rod drives the first sliding rod to slide inside the first joint and the first fixing block. The elasticity of the first spring allows the first sliding rod to slide back and forth inside the first joint and the first fixing block. The first limiting plate is fixed to one end of the first sliding rod and slides inside the first fixing block to limit the movement of the first sliding rod.

[0008] Preferably, the crimping assembly includes a second connector, which is installed at one end of the first connector. A second fixing block is fixedly connected inside the second connector, and a second slide rod is slidably connected inside the second fixing block. A second pull rod is fixedly connected to one end of the second slide rod, a second spring is installed on the outer wall of the second slide rod, a second limiting plate is fixedly connected to one end of the second slide rod, and a sealing strip is provided at one end of the second connector.

[0009] Preferably, the first slide rod is slidably connected to one end of the first fixed block.

[0010] Preferably, the first limiting plate is slidably connected to the inner wall of the first connector, and the first spring is installed at the top of the first connector.

[0011] Preferably, one end of the first connector is provided with a positioning groove, the first slide rod is slidably connected in the positioning groove, and the first spring is installed at one end of the positioning groove.

[0012] Preferably, the second pull rod is installed at one end of the second fixed block, the second spring is disposed at one end of the second fixed block, and the second limiting plate is slidably connected to the inner wall of the second fixed block.

[0014] Preferably, one end of the second connector is provided with a through groove, the second slide rod is slidably connected in the through groove, and the second spring is installed at one end of the through groove.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the tooth clip is fixed by the surrounding block, so that the protruding part of the tooth clip can rebound due to its toughness. By pulling the first pull rod, the first slide rod is driven to slide inside the first joint and the first fixing block. The elasticity of the first spring is used to make the first slide rod slide back and forth inside the first joint and the first fixing block to achieve a quick disassembly effect.

[0016] 2. In this utility model, by pulling the second pull rod, the second slide rod can slide inside the second joint and the second fixed block, and the second spring is used to make the second slide rod slide back and forth. The second limiting plate prevents the second slide rod from disengaging from the first joint, thereby achieving the crimping effect. Attached Figure Description
