Description

Technical Field

[0001] This utility model relates to the field of plug technology, specifically an anti-loosening wire harness connection plug. Background Technology

[0002] A wire harness connector plug is a type of connecting component, mainly used for connecting wire harness terminals. It can limit the terminals of the wire harness internally, and can connect to the terminals when the pins of another plug are inserted, enabling quick connection and disconnection of the circuit.

[0003] The connector plugs in existing products have slots inside for fixing wire harnesses and terminals. The terminals are installed inside the plug by limiting and positioning them using internal baffles. Since there is no structure to assist in disassembling the terminals, when disassembling the terminals inside the plug, a push pin is needed to push the internal terminals and then pull the external wire harness to disassemble the terminals, which is quite troublesome when replacing them.

[0004] To address these issues, we offer a non-loosening wire harness connector. Utility Model Content

[0005] 1) Technical problems to be solved This utility model proposes an anti-loosening wire harness connector plug, which solves the problem of the lack of auxiliary disassembly structure for the terminals through the cooperation between the spring and the top plate.

[0006] (ii) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening wire harness connector plug, including a connector head one, a connector head two being snapped onto the outside of the connector head one, multiple sets of through holes being opened on the inner wall of the connector head one, and multiple sets of fixing brackets being fixedly installed on the inner wall of the connector head one. The inner wall of the connector is slidably connected to a mounting bracket. The inner wall of the mounting bracket is fixedly installed with a pressure plate and a top plate. The mounting bracket is slidably connected to a positioning rod, and the positioning rod is sleeved with a spring. A wedge plate one is fixedly installed on the upper surface of the mounting bracket, a wedge plate two is slidably connected to the outer surface of the wedge plate one, and an elastic buckle is fixedly installed on the outer surface of the wedge plate two.

[0007] Furthermore, the fixing frame has a U-shaped structure and a baffle at one end, and a sliding groove is provided at the bottom of the fixing frame, with the outer surface of the top plate slidably connected to the inner wall of the sliding groove.

[0008] Furthermore, the pressure plate and the top plate are arranged in opposite directions, and the terminals of the wire harness are installed between the pressure plate and the top plate. The pressure plate presses down on the terminals, and the top plate pushes up on the terminals.

[0009] Furthermore, one end of the positioning rod is fixedly installed to the inner wall of the connector, and multiple sets of positioning rods and springs are symmetrically arranged.

[0010] Furthermore, one end of the spring is fixedly installed to the inner wall of the mounting bracket, and the other end of the spring is fixedly installed to the inner wall of the connector, and the spring pushes the mounting bracket to move upward.

[0011] Furthermore, both the first and second wedge plates are provided with inclined surfaces and are arranged in opposite directions. The top of the first connector is provided with a positioning hole, and the outer surface of the elastic buckle engages with the inside of the positioning hole.

[0012] Furthermore, a lever is fixedly installed on the upper surface of the second wedge plate, and the outer surface of the lever is slidably connected to the interior of the first connector.

[0013] (iii) Beneficial effects: Compared with existing technologies, this anti-loosening wire harness connector has the following advantages: 1. This anti-loosening wire harness connector plug, through the cooperation between the spring and the top plate, uses the pressure plate to press down and fix the terminals. When disassembling the terminals, wedge plate one and wedge plate two are disengaged. At this time, the spring can push the mounting bracket to move, and the top plate inside the mounting bracket can push the terminals inside the fixing bracket to move upward, which can release the limitation on the terminals. At this time, the terminals can be disassembled by directly pulling the wire harness from the outside of the plug without the use of additional tools. This realizes the function of assisting in the disassembly of the internal terminals of the plug, which is conducive to the quick disassembly of the internal terminals.

[0014] 2. This anti-loosening wire harness connector plug, by setting up components such as elastic buckles, ensures that when the pressure plate presses down to fix the terminal, the inclined surfaces of wedge plate one and wedge plate two are in full contact. At this time, the elastic buckle can enter the interior of the positioning hole, and the position of the mounting bracket is fixed, which can quickly fix the terminal. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-loosening wire harness connector plug, including a connector head 1, a connector head 2 that is snapped onto the outside of the connector head 1, a buckle with an elastic structure installed inside the connector head 1, and a fixing hole corresponding to the buckle inside the connector head 2. When the connector head 1 and the connector head 2 are snapped together, the buckle achieves a stable anti-loosening effect.

[0020] The inner wall of connector 1 has multiple sets of through holes 3, and multiple sets of fixing brackets 4 are fixedly installed on the inner wall of connector 1. The fixing bracket 4 has a U-shaped structure and a baffle 13 is provided at one end. The wire harness and terminal are inserted into the interior of connector 1 through the through holes 3. At this time, the terminal of the wire harness enters the interior of the fixing bracket 4. The fixing bracket 4 and the baffle 13 form a limiting area inside the fixing bracket 4. At this time, the terminal cannot be easily pulled out inside the fixing bracket 4.

[0021] The inner wall of connector 1 is slidably connected to a mounting bracket 5. The inner wall of the mounting bracket 5 is fixedly installed with a pressure plate 6 and a top plate 7. The bottom of the mounting bracket 4 is provided with a sliding groove 14. The outer surface of the top plate 7 is slidably connected to the inner wall of the sliding groove 14. The pressure plate 6 and the top plate 7 are arranged in opposite directions. The terminals of the wire harness are installed between the pressure plate 6 and the top plate 7. The pressure plate 6 presses down on the terminals, and the top plate 7 pushes up on the terminals. Each set of pressure plates 6 and top plates 7 are arranged vertically inside the mounting bracket 4. When the pressure plate 6 is pressed down, it can position the terminals. When the top plate 7 is pushed up, it can push the internal terminals of the mounting bracket 4 to move, allowing the terminals to be released from the limiting area of ​​the baffle 13. At this time, the terminals can be pulled out directly.

[0022] The mounting bracket 5 has a sliding connection of a positioning rod 8 inside. One end of the positioning rod 8 is fixedly installed to the inner wall of the connector 1. Multiple sets of positioning rods 8 and springs 9 are symmetrically arranged. By using the limiting of multiple sets of positioning rods 8, the mounting bracket 5 can only move up and down inside the connector 1, which improves the stability of the mounting bracket 5 when it moves. The positioning rod 8 is covered with a spring 9. One end of the spring 9 is fixedly installed to the inner wall of the mounting bracket 5, and the other end of the spring 9 is fixedly installed to the inner wall of the connector 1. The spring 9 pushes the mounting bracket 5 to move upward. When the mounting bracket 5 is not limited, the spring 9 can push the mounting bracket 5 to move upward. At this time, multiple sets of top plates 7 inside the mounting bracket 5 can push the terminals to move, and multiple sets of terminals can be disassembled at the same time.

[0023] A wedge plate 10 is fixedly mounted on the upper surface of the mounting bracket 5. A wedge plate 21 is slidably connected to the outer surface of the wedge plate 10. Both the wedge plate 10 and the wedge plate 211 have inclined surfaces arranged in opposite directions. A lever plate 16 is fixedly mounted on the upper surface of the wedge plate 211. The outer surface of the lever plate 16 is slidably connected to the inside of the connector 1. The lever plate 16 is set as a T-shaped structure and can slide in the limiting groove at the top of the connector 1. The lever plate 16 can limit the wedge plate 21. When the wedge plate 10 and the wedge plate 211 come into contact, the wedge plate 21 can exert downward pressure on the wedge plate 10. At this time, the wedge plate 10 and the mounting bracket 5 will move downward inside the connector 1, which can further drive the pressure plate 6 to press down and fix the terminal.

[0024] An elastic buckle 12 is fixedly installed on the outer surface of the second wedge plate 11. A positioning hole 15 is opened on the top of the connector 1. The outer surface of the elastic buckle 12 engages with the inside of the positioning hole 15. When the terminal is fixed, the second wedge plate 11 moves to the maximum position. At this time, the elastic buckle 12 enters the inside of the positioning hole 15. At this time, the reset of the second wedge plate 11 is limited. The positions of the first wedge plate 10 and the second wedge plate 11 are stable and fixed. When making contact, it is only necessary to press down one end of the elastic buckle 12.

[0025] Working principle: When fixing the wire harness terminal, the terminal and wire harness are directly inserted into the inside of connector 1. Then, control the wedge plate 11 to move to the maximum position so that the elastic buckle 12 enters the inside of the positioning hole 15. At this time, the wedge plate 11 will press down the wedge plate 10, and the pressure plate 6 inside the mounting bracket 5 will press down the terminal to fix the terminal. When disassembling the terminal, press down the elastic buckle 12. At this time, the spring 9 can push the mounting bracket 5 to move upward. The top plate 7 inside the mounting bracket 5 will push the terminal inside the fixing bracket 4 to move upward and get away from the limit of the baffle 13. At this time, the terminal inside the connector 1 can be pulled out directly.
