[0031] Example

[0032] See also Figures 1 to 6 This embodiment provides an integrated wiring harness connector, including multiple connecting wires 1 and a shell 2. The multiple connecting wires 1 each include a plug-in portion 11 and a fixed portion 12. The fixed portions 12 of the multiple connecting wires are arranged at intervals. The shell 2 is wrapped around the fixed portions 12 of the multiple connecting wires 1. The plug-in portions 11 of the multiple connecting wires 1 extend to the outside of the shell 2 to form connecting pins.

[0033] In this embodiment, the plurality of connecting wires 1 may be composed of wires of different specifications and colors, and each connecting wire 1 carries a different electrical signal or voltage.

[0034] The outer skin of the end of the connecting wire 1 is removed to expose 20mm±5mm of the wire, wherein the exposed wire is the plug-in part 11, and the fixed part 12 is the partially skinned wire and the partially exposed wire combined with the plug-in part. The connecting wires 1 are arranged according to preset requirements and fixed in the mold to keep the correct position and spacing between the connecting wires 1 to avoid interference or short circuit between the connecting wires 1. Through the injection molding process, the outside of the fixing part 12 of the multiple connecting wires 1 is wrapped with molten shell material. Under high pressure, the shell material is cooled and solidified to form a shell 2 that perfectly matches the arrangement of the multiple connecting wires 1 and the shape of the connector. While ensuring the appearance quality and dimensional accuracy of the connector, it can also effectively fix the multiple connecting wires 1 and internal components, thereby ensuring the durability and reliability of the connector.

[0035] In order to ensure the arrangement efficiency and accuracy of the connecting wires 1, the mold is provided with a plurality of wire grooves arranged at intervals. The connecting wires are placed into the wire grooves one by one for positioning and fixing, so that the correct position and spacing between the connecting wires are maintained, thereby greatly increasing the arrangement efficiency of the connecting wires.

[0036] The shell material is preferably nylon rubber, which is widely used in the manufacture of wiring harness connectors due to its excellent wear resistance, heat resistance, oil resistance and chemical stability. During the molding process of the shell 2, it can fill the gaps between the connecting wires 1, enhance the overall structural strength of the connecting wires 1, and provide good insulation and sealing effects, preventing the intrusion of water vapor, dust and corrosive substances, and effectively extending the service life of the connector.

[0037] The plug-in portion 11 and the fixing portion 12 may be arranged at an angle to adapt to different plug-in environments. For example, the angle between the plug-in portion 11 and the fixing portion 12 is 90 degrees, which facilitates installation of the connector at a position with an upper limit on a circuit board.

[0038] In one embodiment, the plug-in portion 11 of the connecting wire 1 is improved to ensure the structural strength of the plug-in portion 11. Specifically, the plug-in portion 11 is provided with a plating layer.

[0039] In this embodiment, by adding a plating layer to the plug-in portion 11 , the plug-in portion 11 can be reinforced and oxidation of the plug-in portion 11 can be prevented.

[0040] Preferably, the plating layer is a tin layer. By applying a layer of solder on the plug-in part 11, the hardness of the plug-in part 11 can be increased to achieve a reinforcement effect, while preventing the plug-in part 11 from being exposed to the air and oxidized. The solder layer can also facilitate subsequent welding work.

[0041] In one embodiment, the structure of the housing 2 is improved to ensure the accuracy of the docking between the connector and the target component. Specifically, the housing 2 is provided with a positioning structure.

[0042] In this embodiment, the positioning structure provides correct guidance and positioning for the connector during the insertion process, so that the connector can be precisely docked with other components or systems.

[0043] Preferably, the positioning structure is a guide pin 21, and the guide pins 21 are respectively provided at both ends of the housing 2 along the width direction.

[0044] A guide pin 21 is provided at each end of the housing 2 along the width direction, and a guide hole is provided corresponding to the target component or system. When the connector is inserted into the target component or system, the guide pin 21 can be inserted into the guide hole, thereby providing correct guidance and positioning for the connector and ensuring accurate electrical connection.

[0045] In one embodiment, the structure of the housing 2 is improved to ensure the reliability of the connection between the connector and the target component or system. The housing 2 is provided with a fixing structure.

[0046] In this embodiment, the fixing structure enables the connector to be aligned with other components or systems and connected, thereby ensuring a tight fit and reliable electrical connection between the connector and the corresponding interface.

[0047] Optionally, a mechanical snap-on / slot is provided on one side of the housing, and a hook is provided at a corresponding position of the target component or system. After the connector is docked with the corresponding interface of the target component or system, the mechanical snap-on / slot is engaged and connected with the hook, thereby ensuring a tight fit and reliable electrical connection between the connector and the corresponding interface.

[0048] Optionally, the fixing structure is a clamping cap 22 , and the clamping cap 22 is arranged at the end of the guide pin 21 .

[0049] A card cap 22 is provided at the end of the guide pin 21 away from the housing, so that after the guide pin 21 of the connector passes through the guide hole, the card cap 22 can fix the connector on the target component or system, ensuring a tight fit and reliable electrical connection between the connector and the corresponding interface.

[0050] In one embodiment, the material of the housing 2 is improved to ensure the structural stability and reliability of the connector as a whole. Specifically, the housing 2 is made of modified engineering plastic.

[0051] In this embodiment, the modified engineering plastic is PA66 + 33% GF, which exhibits excellent mechanical properties, high-temperature resistance, and impact resistance. Its high strength and toughness allow it to withstand significant impact loads and bending stresses. Furthermore, its excellent high-temperature resistance allows it to withstand long-term use at high temperatures without deformation or damage, effectively ensuring the durability of the connector.

[0052] Similarly, the material of the shell can also be PBT-GF30. PBT-GF30 is a high-quality thermoplastic composite material. The composite material is made by reinforcing polybutylene terephthalate (PBT) resin with 30% glass fiber. It has the advantages of excellent mechanical properties, dimensional stability, low water absorption, excellent electrical properties, chemical resistance and oil resistance, high heat resistance and self-lubrication, which can effectively ensure the durability of the connector.

[0053] From the above description, it can be seen that the beneficial effect of the utility model is that it provides an integrated wiring harness connector with a reasonable structure, which can effectively simplify the installation process of the connector and reduce the installation difficulty and cost. The connector effectively reduces the use of external connectors by tightly combining nylon rubber and the connecting harness, improves the system integration, enhances the sealing, waterproofness and wear resistance of the connector, and effectively improves the reliability and service life of the wiring harness connector.

[0054] It is easy for those skilled in the art to understand that the above embodiments can be freely combined and superimposed without conflict.

[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
