Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, specifically a wire harness connector for automotive wire harness connection. Background Technology

[0002] Wiring harness connectors are the "neuron nodes" of a vehicle's electrical system. Through mechanical locking structures and plated terminals, they enable precise circuit connection between the wiring harness and devices such as ECUs, sensors, and actuators. In automobiles, wiring harness connectors are mainly used in systems such as BMS, air conditioning, and headlights in fuel vehicles, and can also be used in high-voltage body electronic units such as battery packs and motors in new energy vehicles.

[0003] In practical applications of automotive wiring harness connectors, ensuring that the connectors do not come loose is crucial. Therefore, wiring harness connectors are typically equipped with limiting structures. Among these, snap-fit ​​structures are the most common type due to their convenience, effectively preventing accidental loosening through the interlocking of two connectors. However, most widely used snap-fit ​​structures are single-sided snap-fit ​​structures; when these structures loosen due to external force or vibration, it can lead to connection failure between the connectors, and in severe cases, may even cause automotive circuit malfunctions, affecting the normal operation and driving safety of the vehicle. Therefore, this type of snap-fit ​​structure has limitations in its use. In light of this, we propose a wiring harness connector for automotive wiring harness connections. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] This embodiment provides a technical solution:

[0028] Please see Figures 1-6As shown, a wiring harness connector for automotive wiring harness connection includes a first connecting part 1; a slot 11 is provided on the front end face of the first connecting part 1, and a plurality of conductors 12 are fixed in the slot 11; a box 14 is fixed on the top of the first connecting part 1, a cavity 140 is provided inside the box 14, and a connecting groove 141 is provided on the front end of the box 14; a rotating body 15 is rotatably installed on both the left and right sides of the cavity 140, and a clamp 150 is fixed on the rear end of the rotating body 15; an extension block 16 is fixed on the front end of the rotating body 15, and a connecting shaft 160 is fixed on the top front end of the extension block 16; a fixed shaft 18 is provided on one side of the extension block 16 and is fixedly connected to the cavity 140; the upper and lower ends of the fixed shaft 18 are fixedly connected to the top of the cavity 140 and the top of the first connecting part 1 by bolts; a hook spring 17 is provided between the fixed shaft 18 and the connecting shaft 160, and the hooks at both ends of the hook spring 17 are respectively engaged with the fixed shaft 18 and the connecting shaft 160.

[0029] Please see Figure 6 As shown, a second connecting part 2 is provided on the front side of the first connecting part 1; a plug block 21 that is inserted into the slot 11 is fixed at the rear end of the second connecting part 2, and a plug hole 210 for the conductor 12 to be inserted is provided on the plug block 21; a connecting seat 23 is fixed at the top of the second connecting part 2, and a limiting plate 24 is fixed at the rear end of the connecting seat 23. The limiting plate 24 passes through the connecting groove 141 and is inserted into the cavity 140. The left and right side walls of the limiting plate 24 are fixed with locking teeth 240, and the locking head 150 engages with the locking teeth 240.

[0030] In this embodiment, the connection between the rotating body 15 and the extension block 16 is located at the top where a drive shaft is fixed. The top end of the drive shaft passes through the top of the housing 14, and a lever 19 is fixed to the top end of the drive shaft. The rotating body 15 is connected to the lever 19 at the top via the drive shaft. This design allows the operator to easily control the rotating body 15 through the lever 19, enabling the separation of the clamp head 150 from the clamp teeth 240, thus simplifying the disassembly and installation process of the wire harness connector.

[0031] In this embodiment, the rotating body 15, the clamping head 150, and the extension block 16 are integrally formed structures, and the cross-sectional shape of the rotating body 15 is whistle-shaped. The integral forming process reduces the connection points between the rotating body 15, the clamping head 150, and the extension block 16, enhancing the overall structural stability, while the whistle-shaped design facilitates the engagement and cooperation between the clamping head 150 and the clamping teeth 240.

[0032] In this embodiment, the rear end of the first connecting part 1 is provided with a plurality of first wiring holes 10, and the front end of the second connecting part 2 is provided with a plurality of second wiring holes 20. The arrangement of the first wiring holes 10 and the second wiring holes 20 facilitates the installation of automotive wiring harnesses.

[0033] In this embodiment, positioning blocks are fixed on both the upper and lower walls of the slot 11, and two positioning slots 211 are formed on both the upper and lower walls of the plug 21. The positioning blocks are inserted into the corresponding positioning slots 211. When the plug 21 is inserted into the slot 11, the positioning blocks and positioning slots 211 quickly match, which not only ensures that the conductor 12 and the socket 210 are accurately connected, but also avoids the plug 21 from shifting during insertion.

[0034] In this embodiment, the connecting seat 23 and the limiting plate 24 are integrally formed, and the connecting seat 23 is fixedly connected to the second connecting part 2 by bolts. The integral forming enhances the structural strength between the connecting seat 23 and the limiting plate 24, while the bolt fixing facilitates the installation and disassembly of the connecting seat 23 and the second connecting part 2, reducing the later maintenance cost.

[0035] In this embodiment, a first fixing block 13 is fixed at the bottom edge of the first connecting part 1, and a positioning hole 130 is fixed at the front end of the first fixing block 13. A second fixing block 22 is fixed at the bottom edge of the second connecting part 2, and a positioning rod 220 is provided at the second fixing block 22 for insertion into the positioning hole 130. This design further improves the reliability and stability of the connection between the first connecting part 1 and the second connecting part 2.

[0036] It should be added that, in this embodiment, a limiting block is coaxially fixed at the top end of the connecting shaft 160, and the diameter of the limiting block is larger than the diameter of the connecting shaft 160; the limiting block plays a limiting role on the hook spring 17, thereby preventing the hook spring 17 from detaching from the connecting shaft 160.

[0037] In practical use, the user first inserts the plug 21 into the slot 11, inserts the positioning block into the positioning groove 211, inserts the conductor 12 into the socket 210, and at the same time, the limiting plate 24 passes through the connecting groove 141 and is inserted into the cavity 140. When the locking tooth 240 passes the locking head 150, under the action of the squeezing force, the locking tooth 240 pushes the locking head 150 to one side. At this time, the hook spring 17 is stretched. After the locking tooth 240 passes the locking head 150, under the elastic action of the hook spring 17, the rotating body 15 is reset and drives the locking head 150 to reset. At this time, the locking head 150 moves to the front side of the locking tooth 240 and engages with the locking tooth 240. At this time, the first connecting part 1 and the second connecting part 2 are connected and fixed.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
