[0020] Example: Refer to Figure 1-Figure 12 A plug and socket connector for an automotive wiring harness comprises a first connector 2 and a second connector 3, one end of the second connector 3 is inserted into the first connector 2, and further comprises: a fixing sleeve 1, the first connector 2 and the second connector 3 are arranged in the fixing sleeve 1; a connecting piece is arranged on the side wall of the first connector 2; a flip driving part is arranged on the fixing sleeve 1, when the flip driving part is coupled with the connecting piece, the first connector 2 is fixed to the fixing sleeve 1; when the flip driving part is separated from the connecting piece, the first connector 2 is separated from the fixing sleeve 1; a limiting ring 31 is fixedly mounted on the outer side of the second connector 3, a sealing ring 4 is sleeved on the second connector 3, when the second connector 3 is inserted into the fixing sleeve 1, the sealing ring 4 abuts against the limiting ring 31.

[0021] In this embodiment, the second connector 3 is finally connected to the wiring harness and then fixedly connected to the fixing sleeve 1, and then the first connector 2 is fixedly connected to another set of wiring harnesses, and then the first connector 2 is inserted into the fixing sleeve 1 until the two sets of connectors are docked, wherein the first connector 2 automatically completes docking with the second connector 3 after being inserted into the fixing sleeve 1, and the sealing ring 4 is used to prevent external moisture from entering the fixing sleeve 1 and causing damage to electrical components.

[0022] Reference Figure 1-Figure 9, the connecting member includes a mounting box 24 fixedly installed on the outer wall of the first joint 2. A convex block 25 is fixedly installed on the mounting box 24. A locking groove 26 is provided on the side of the convex block 25 away from the second joint 3. The flipping driving part includes a handle 5, and the handle 5 is in a "C" shape. When the handle 5 is connected to the convex block 25, the handle 5 is clamped in the locking groove 26; a sleeve hole 51 is provided on the handle 5. A connecting shaft 11 is fixedly installed on the side wall of the fixed sleeve 1. A first reinforcing rib 12 is fixedly connected to the connecting shaft 11, and the first reinforcing rib 12 is fixedly connected to the fixed sleeve 1. The connecting shaft 11 is inserted into the sleeve hole 51. A driving groove 52 is formed on the side wall of the handle 5. A driven shaft 22 is fixedly installed on the side wall of the first joint 2. A second reinforcing rib 23 is fixedly installed on the driven shaft 22, and the second reinforcing rib 23 is fixedly connected to the first joint 2. The driven shaft 22 is inserted into the driving groove 52; when the notch at the top of the driving groove 52 is located on the side of the sleeve hole 51, the bottom of the driving groove 52 is located below the sleeve hole 51; an installation groove 18 is provided on the fixed sleeve 1. When the handle 5 is toggled, the handle 5 rotates around the connecting shaft 11. While the driven shaft 22 moves along the groove wall of the driving groove 52, the driven shaft 22 makes a linear motion along the installation groove 18. A third moving groove 27 is provided on the mounting box 24. When the handle 5 is inserted into the locking groove 26 or the handle 5 is disengaged from the locking groove 26, the convex block 25 moves downward.

[0023] As Figure 1 shown, when the connection is completed, the handle 5 is clamped on the locking groove 26 on the convex block 25. The handle 5 and the convex block 25 are in an interference fit, further improving the stability between the handle 5 and the locking groove 26, thereby improving the overall stability of the plug connector.

[0024] As Figure 3 shown, when it is necessary to separate the first joint 2 from the fixed sleeve 1, rotate the handle 5 so that the top plate of the handle 5 is disengaged from the locking groove 26. Then, through the cooperation of the connecting shaft 11, the driven shaft 22 and the sleeve hole 51, the first joint 2 and the fixed sleeve 1 are disengaged from the engaged state, automatically completing the separation of the connection of the two ends of the wire harness and reducing the difficulty of separating the wire harness.

[0025] Referring to Figure 1 、 Figure 5 and Fig.12 , a third chuck 53 is fixedly installed on the inner side of the handle 5. A second limiting groove 111 is formed on the side wall of the fixed sleeve 1. When the handle 5 is engaged with the convex block 25, the third chuck 53 abuts against the second limiting groove 111.

[0026] Among them, the second limiting groove 111 is sleeved with the third chuck 53 for cooperation. When the handle 5 is engaged into the locking groove 26, the third chuck 53 abuts against the second limiting groove 111, making the handle 5 closely adhere to the convex block 25, eliminating the gap between the handle 5 and the convex block 25, improving the stability of the connection between the handle 5 and the convex block 25, and further improving the stability between the first joint 2 and the fixed sleeve 1.

[0027] Reference Figure 1 , Figure 8 , Fig. 9 and Fig.12 A third limiting strip 21 is fixedly mounted on the first joint 2 , and a first limiting groove 17 is provided on the fixing sleeve 1 . When the first joint 2 is inserted into the fixing sleeve 1 , the third limiting strip 21 is inserted into the first limiting groove 17 .

[0028] When inserting the first connector 2 into the fixing sleeve 1 , align the third limiting strip 21 with the first limiting groove 17 , and then insert the third limiting strip 21 into the first limiting groove 17 to prevent the connected first connector 2 from shaking in the fixing sleeve 1 .

[0029] Reference Figure 2 , Figure 8 and Fig.12 A limiting plate 19 is fixedly installed on the fixing sleeve 1, a second card slot 110 is provided at the bottom of the limiting plate 19, and a second clamping head 28 is fixedly installed on the first connector 2. When the first connector 2 is plugged into the fixing sleeve 1, the second clamping head 28 engages with the second card slot 110.

[0030] When the first connector 2 is inserted into the fixing sleeve 1 and the handle 5 is inserted into the locking groove 26, the second clamping head 28 is inserted into the second clamping groove 110, further preventing the first connector 2 from being separated from the fixing sleeve 1 during use, and preventing the handle 5 from being disengaged from the locking groove 26 due to the vibration generated by the operation of the vehicle.

[0031] Reference Figure 1-Figure 3 and Figure 7 , Figure 8 , Figure 10-12 A first clamping head 14 is fixedly installed on the inner side of the fixed sleeve 1, a first movable groove 15 is provided on the fixed sleeve 1, and the first movable groove 15 is arranged below the first clamping head 14. A fourth clamping head 32 is arranged on the outer side of the second joint 3. When the second joint 3 is inserted into the fixed sleeve 1, the first clamping head 14 is engaged with the fourth clamping head 32, and the left and right sides of the inner wall of the fixed sleeve 1 are fixedly installed with second limiting strips 16, and the left and right sides of the second joint 3 are provided with third limiting slots 33; the upper and lower sides of the inner wall of the fixed sleeve 1 are fixedly installed with first limiting strips 13, and the upper and lower sides of the second joint 3 are provided with fourth limiting slots 34; when the second joint 3 is inserted into the fixed sleeve 1, the second limiting strip 16 is inserted into the third limiting slot 33, and the first limiting strip 13 is inserted into the fourth limiting slot 34.

[0032] When in use, insert the second connector 3 into the fixing sleeve 1. After insertion, the first limiting strip 13 abuts against the fourth limiting groove 34, and the second limiting strip 16 abuts against the third limiting groove 33. At the same time, the first chuck 14 is inserted into the fourth card slot 32 to fix the second connector 3 and the fixing sleeve 1. Meanwhile, the cooperation between the first limiting strip 13 and the fourth limiting groove 34, and between the second limiting strip 16 and the third limiting groove 33 prevents the second connector 3 from continuing to be inserted into the fixing sleeve 1. The cooperation between the first chuck 14 and the fourth card slot 32 can prevent the second connector 3 from detaching from the fixing sleeve 1, thereby locking the fixing sleeve 1 and the second connector 3 together.

[0033] In summary, through the coupling and detachment of the flipping drive part (handle 5) and the connecting part (protrusion 25 and locking groove 26), the user can quickly fix or separate the first connector 2 and the fixing sleeve 1, thus conveniently connecting or disconnecting two groups of wire harnesses, reducing the difficulty of connecting and separating the wire harnesses, and improving the efficiency of replacement and repair. When the handle 5 is clamped in the locking groove 26 of the protrusion 25, an interference connection is formed between them, further enhancing the connection stability. In addition, the cooperation between the third chuck 53 and the second limiting groove 111, and the engagement between the second chuck 28 and the second card slot 110 further improve the overall stability of the connector, preventing shaking or falling off during use. The setting of the sealing ring 4 effectively prevents external moisture from entering the fixing sleeve 1, protects the internal electrical components from damage, and improves the durability and safety of the connector. Through the cooperation of the first limiting strip 13, the fourth limiting groove 34, the second limiting strip 16 and the third limiting groove 33, and the insertion of the third limiting strip 21 into the first limiting groove 17, the connector is effectively limited and guided during the insertion process, ensuring the correct docking and fixing of the connectors. The "C"-shaped design of the handle 5 and the setting of the driving groove 52 enable the user to complete the connection or separation operation by simply拨动 the handle 5, without the need to use additional tools or complex steps. The overall design of the connector is compact, and the cooperation between components is tight, which not only ensures the reliability of the connection but also saves space, making it convenient to use in limited spaces such as in automobiles.

[0034] A connection method for a plug and socket connector for an automotive wire harness includes the following steps: Step 1: Connect the first connector 2 and the second connector 3 to two groups of wire harnesses respectively and fill them in the wiring holes. Step 2:套接 the sealing ring 4 on the second connector 3. Step 3:插接 the second connector 3 on the fixing sleeve 1 and make the first chuck 14 snap into the fourth limiting groove 34 to fix the second connector 3 on the fixing sleeve 1. Step 4: Insert the first connector 2 into the fixing sleeve 1 , and then rotate the handle 5 to make the handle 5 snap into the locking groove 26 .

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
