Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a wire harness connector with a limiting structure. Background Technology

[0002] Wire harness connectors are key components used in electrical equipment or systems to connect, fix, and conduct current through multiple wires. They are widely used in automotive, electronics, communications, industrial control, and other fields. They not only conduct electricity but also protect, organize, and facilitate the maintenance of wiring. As modern industry demands increasingly higher reliability for electrical connections, the requirements for wire harness connectors in terms of structural design, installation methods, and operational stability are also rising.

[0003] An existing line connector with a wire harness structure (see utility model patent CN 215600674U) discloses a structure including a line connector body, a fixing component, and bolts. The front end has a first operating handle and a second operating handle, and wires are inserted and connected through a wire insertion hole. The rear end has a fixing component consisting of a suction cup, a fixing plate, and a limiting block. The suction cup adheres to the mounting surface, achieving quick fixing, while a storage frame can hold excess wire. Although this structure improves installation efficiency and achieves initial wire organization and fixing, the following prominent problems still exist in practical applications:

[0004] During prolonged use, suction cup structures are prone to detachment due to aging, dust accumulation, or external pulling, causing the entire connector to lose its fixed support. The wire may fall off along with the connector. Once the suction cup fails, the wire will fall downwards under the action of gravity or external force. This fall will generate tensile stress on the insertion part between the wire and the connector, thereby affecting the stability of the contact and even causing safety hazards such as open circuit or poor contact.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a wire harness connector with a limiting structure to solve this problem. This wire harness connector should significantly improve the stability and tensile strength of the wire connection, while better meeting the needs of complex operating conditions, providing strong support for the safer and more efficient development of electrical connections. Utility Model Content

[0006] The purpose of this invention is to provide a wire harness connector with a limiting structure, which solves the problem that the suction cup structure in the prior art is prone to falling off due to aging, dust accumulation or external pulling during long-term use, causing the entire connector to lose its fixed support and the wire to fall off with the connector.

[0007] To achieve the above objectives, this utility model provides a wire harness connector with a limiting structure, including a wire connector and two mounting bases. The top side of the wire connector has a plurality of terminals, and the other side of the top has a plurality of lead grooves corresponding to the terminals. Each terminal is connected to a wire.

[0008] Two mounting bases are symmetrically arranged on both sides of the bottom of the line connector. Several wire harness plates are arranged between the two mounting bases. Both sides of the two mounting bases are connected by guide structures. Both ends of the wire harness plates are slidably engaged with the adjacent guide structures.

[0009] The cable tray has several cable tray grooves on one side. The top of the mounting base is connected to the bottom of the line connector through a limiting frame. A limiting plate is slidably connected inside the limiting frame. A vertical adjustment structure is provided at one end of the limiting plate.

[0010] The mounting base has several mounting holes on both sides of its top. The top of the limiting frame is fixedly connected to the bottom of the line connector with bolts, and the bottom is fixedly connected to the top of the mounting base with bolts.

[0011] The limiting frame is made of metal, and the bottom of the mounting base has a bottom groove.

[0012] The guide structure includes two guide rods, with each end of the guide rod connected to one of the two mounting bases, and the end of the cable tray slidingly engaged with the guide rods.

[0013] The limiting frame has movable slots that penetrate the limiting frame on both sides, and the limiting plate has movable plates that slide through the movable slots at both ends.

[0014] The limiting frame has side plates fixedly connected to the top of both sides. The vertical adjustment structure includes an adjustment screw. One end of the adjustment screw is threaded through the moving plate and rotatably connected to the bottom of the side plate. The other end is rotatably connected to the handle set in the bottom groove through the mounting base.

[0015] This utility model discloses a wire harness connector with a limiting structure, which eliminates the traditional suction cup fixing method and adopts a solution where the mounting base is directly fixed to the external structure. This effectively solves the problem of suction cups aging and falling off during long-term use, and avoids the risk of connectors and wires falling off due to fixing failure, greatly improving the safety and service life of the product in practical applications. Secondly, through the sliding cooperation between the limiting plate and the limiting frame and the design of the vertical adjustment structure, precise control of the wire clamping force is achieved, ensuring that the wire is in a stable compressed state inside the connector. This effectively prevents electrical faults such as poor contact and open circuits caused by wire sagging due to gravity or external pulling, thereby improving the electrical performance and reliability of the connector. Secondly, the sliding connection between multiple wire harness boards via a guide structure allows for flexible adjustment of spacing and position according to actual wiring needs. This enables the device to adapt to various wire diameters, wire counts, and wiring methods, enhancing the product's versatility and adaptability, and meeting diverse usage requirements under complex working conditions. Furthermore, the corresponding arrangement of lead slots and terminals further optimizes wire routing, improves wiring efficiency, and reduces the possibility of human error. Finally, the overall structure is rationally laid out and easy to operate. While improving the fixing stability and tensile strength of the wire harness connector, it also reduces the frequency of subsequent maintenance and usage costs, providing practical technical support for the safety, stability, and efficiency of wire harness connections in modern industrial electrical systems.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a wire harness connector with a limiting structure in this embodiment includes a wire connector 2 and two mounting bases 1. The two mounting bases 1 are symmetrically arranged on both sides of the bottom of the wire connector 2. A plurality of wire harness plates 7 are arranged between the two mounting bases 1. Both sides of the two mounting bases 1 are connected by a guide structure. Both ends of the wire harness plates 7 are slidably engaged with the adjacent guide structure. A plurality of wire harness grooves 9 are opened on one side of the wire harness plates 7. The top of the mounting base 1 is connected to the bottom of the wire connector 2 through a limiting frame 6. A limiting plate 12 is slidably connected inside the limiting frame 6. A vertical adjustment structure is provided at one end of the limiting plate 12.

[0026] During the installation of wire 5, one end of wire 5 is first inserted through the limiting frame 6 on one side of the line connector 2, and then sequentially passed through the cable trays 9 on multiple cable trays 7. The wires are then aligned along a set path through a sliding fit, effectively organizing and positioning wires of different specifications and quantities. The wires then continue to extend through the limiting frame 6 on the other side, and are guided by the lead-in groove 3, finally completing an electrical connection with the conductive components inside the terminal 4. During this process, the vertical adjustment structure drives the limiting plate 12 to slide up and down within the limiting frame 6, allowing the limiting plate to control the inserted wires. Apply uniform pressure to stably press and fix it inside the limiting frame, preventing the wire from loosening or shifting due to external force or gravity. At the same time, two mounting bases 1 are respectively set on both sides of the bottom of the line connector 2, and form a sliding connection with several wire harness plates 7 through a guide structure. This not only enhances the stability of the overall structure, but also allows for flexible adjustment of the position of the wire harness plates to adapt to the needs of wire harness arrangement with different widths. In addition, the mounting base 1 can also be firmly connected to the external mounting surface by bolts or other mechanical fixing methods, replacing the traditional suction cup structure, fundamentally improving the overall installation stability and long-term reliability of the connector.

[0027] Example 2

[0028] Please see Figure 1-5 As shown in the figure, in this embodiment, a wire harness connector with a limiting structure has several mounting holes 16 on both sides of the top of the mounting base 1. The top of the limiting frame 6 is bolted to the bottom of the wire connector 2, and the bottom is bolted to the top of the mounting base 1. Specifically, by setting the mounting holes 16, multiple mounting holes 16 are opened on both sides of the top of the mounting base 1, so that the top of the limiting frame 6 and the bottom of the wire connector 2, and the bottom of the limiting frame 6 and the top of the mounting base 1 can be bolted together. This design not only simplifies the installation process, but also improves the stability and reliability of the overall structure, ensuring that it will not loosen due to vibration or external force during long-term use.

[0029] The guiding structure includes two guide rods 8, with each end of the guide rod 8 connected to one of the two mounting bases 1. The end of the cable tray 7 is slidably engaged with the guide rods 8. Specifically, by setting the guide rods 8, the guiding structure is designed to include two guide rods 8, each end of which is connected to one of the two mounting bases 1, and the end of the cable tray 7 is slidably engaged with the guide rods 8. This ensures that the cable tray 7 can move smoothly along the guide rods 8, allowing for flexible position adjustment to adapt to the needs of cable trays with different width distributions, thereby improving the versatility and adaptability of the device.

[0030] Example 3

[0031] Please see Figure 1-5 As shown, in this embodiment, a wire harness connector with a limiting structure is provided. The limiting frame 6 is made of metal, and the bottom of the mounting base 1 is provided with a bottom groove 10. Specifically, by using the limiting frame 6 made of metal and the bottom groove 10, the high strength of the metal material enhances the limiting frame 6's resistance to pressure and deformation. At the same time, the design of the bottom groove 10 provides space for the adjusting screw 13, making it easy to operate the handle, thereby facilitating the adjustment of the vertical adjustment structure and improving the ease of operation and maintenance efficiency of the equipment.

[0032] Both sides of the limiting frame 6 are provided with moving grooves 14 that penetrate the limiting frame 6. Both ends of the limiting plate 12 are connected to moving plates 11 that slide through the moving grooves 14. Specifically, by setting the moving grooves 14 and moving plates 11, moving grooves 14 that penetrate the limiting frame 6 are opened on both sides of the limiting frame 6, and the moving plates 11 that slide through the moving grooves 14 are connected to both ends of the limiting plate 12. This design allows the limiting plate 12 to move up and down as needed, ensuring that it can apply uniform pressure to the inserted wire and stably press and fix it inside the limiting frame, preventing the wire from loosening or shifting due to external force or gravity, and improving the stability of the wire fixation.

[0033] Side plates 15 are fixedly connected to the top of both sides of the limiting frame 6. The vertical adjustment structure includes an adjusting screw 13. One end of the adjusting screw 13 is threaded through the moving plate 11 and rotatably connected to the bottom of the side plate 15. The other end is rotatably connected to the handle set in the bottom groove 10 through the mounting base 1. Specifically, by setting the side plates 15 and adjusting screw 13, the side plates 15 are fixedly connected to the top of both sides of the limiting frame 6. The vertical adjustment structure is designed to include the adjusting screw 13. One end of the adjusting screw 13 is threaded through the moving plate 11 and rotatably connected to the bottom of the side plate 15. The other end is rotatably connected to the handle set in the bottom groove 10 through the mounting base 1. In this way, the lifting and lowering of the adjusting screw 13 can be precisely controlled by rotating the handle, thereby driving the limiting plate 12 to move up and down. This achieves fine adjustment of the height of the limiting plate 12, ensuring effective clamping of wire harnesses of different thicknesses and improving the flexibility and practicality of the entire device.

[0034] This solution includes the following workflow:

[0035] During the installation of wire 5, the entire device is first securely fixed to the external mounting surface through multiple mounting holes 16 on both sides of the top of the mounting base 1. Then, the operator inserts one end of wire 5 through the limiting frame 6 on one side of the line connector 2. The limiting frame 6 is made of metal and has good pressure and deformation resistance, ensuring structural stability during long-term use. The wire then passes sequentially through the cable trays 9 on several cable tray plates 7. Because the two ends of the cable tray plates 7 slide against the guide rods 8 in the guide structure, they can move along the guide rods 8 according to actual wiring requirements to adapt to cable bundle arrangements of different widths, achieving flexible layout and uniform force distribution. The wire continues to extend and passes through the limiting frame 6 on the other side, then, guided by the lead-in groove 3, finally connects with the connector. The conductive components inside the wire end 4 complete the electrical connection. During this process, the limiting plate 12 passes through the moving plates 11 connected at both ends of the limiting frame 6 through the moving slots 14 opened on both sides, and cooperates with the vertical adjustment structure. By rotating the handle in the bottom slot 10, the adjusting screw 13 is driven to rotate. One end of the adjusting screw 13 is threaded through the moving plate 11, and the other end is rotatably connected to the bottom of the side plate 15 fixed at the top of the limiting frame 6, thereby driving the limiting plate 12 to slide up and down, applying uniform pressure to the wire that has been inserted, and pressing it firmly and fixing it inside the limiting frame 6 to prevent loosening or displacement caused by external force or gravity. At the same time, the line connector 2 is bolted to the mounting base 1 and the line connector body through the top and bottom of the limiting frame 6, respectively, further enhancing the stability of the overall structure.

[0036] Compared to existing technologies, this structure offers the following significant advantages: First, it eliminates the traditional suction cup fixing method, adopting a solution where the mounting base 1 is directly fixed to the external structure. This effectively solves the problem of suction cups aging and falling off during prolonged use, avoiding the risk of connectors and cables falling due to fixing failure, and greatly improving the safety and lifespan of the product in practical applications. Second, through the sliding cooperation between the limiting plate 12 and the limiting frame 6, as well as the design of the vertical adjustment structure, precise control of the clamping force on the cable 5 is achieved, ensuring that the cable is stably compressed inside the connector. The design effectively prevents electrical faults such as poor contact and open circuits caused by wire sagging due to gravity or external pulling, thereby improving the electrical performance and reliability of the connector. Furthermore, the multiple cable trays 7 are slidably connected by guide rods 8 in the guide structure, allowing for flexible adjustment of spacing and position according to actual wiring needs. This enables the device to adapt to various wire diameters, wire counts, and wiring methods, enhancing the product's versatility and adaptability, and meeting diverse usage requirements under complex working conditions. In addition, the corresponding arrangement of the lead groove 3 and the terminal block 4 further optimizes the wire routing, improves wiring efficiency, and reduces... To minimize the possibility of human error, the limiting frame 6 is made of metal, and its bottom groove 10 provides operating space for the adjusting screw 13, which not only improves the overall structural strength but also facilitates handle operation, enhancing the ease of operation and maintenance efficiency of the equipment. Furthermore, the top of the limiting frame 6 is bolted to the bottom of the line connector 2, and the bottom of the limiting frame 6 is bolted to the top of the mounting base 1. The mounting base 1 also has multiple mounting holes 16 on its top, making the overall structure more robust and reliable, with strong anti-vibration and anti-fatigue performance. Finally, the limiting plate 12 is connected to the limiting frame via the moving plate 11. The movable slot 14 on the 6 form a sliding fit and is driven by the vertical adjustment structure composed of the adjusting screw 13 and the side plate 15, realizing the fine adjustment function in the height direction. This ensures effective clamping of wire harnesses of different thicknesses and further improves the flexibility, practicality and applicability of the entire device. In summary, this wire harness connector has a reasonable structure and is easy to operate. While improving the fixing stability and tensile strength of the wire harness connector, it also reduces the frequency of later maintenance and the cost of use, providing practical technical support for the safety, stability and efficiency of wire harness connections in modern industrial electrical systems.
