Description

Technical Field

[0001] The present invention relates to the field of wire harness connectors, and specifically to a wire harness connector, production equipment and its process. Background Art

[0002] In some wire harness connectors, in order to ensure the connection stability between the conductive pins and the injection molded housing of the connector, conductive pins with a stepped design are generally used, and the stepped part is encapsulated inside the injection molded housing of the connector. However, this design brings certain challenges during the processing. To ensure that the conductive pins can be accurately and stably inserted into the mold, it is usually necessary to rely on a special vibrating bowl combined with a manipulator, or manually insert each conductive pin one by one. When the wire harness connector needs to be equipped with multiple conductive pins, this processing method becomes particularly cumbersome and inefficient. Because whether using a vibrating bowl combined with a manipulator or manual operation, each conductive pin needs to be processed one by one, which undoubtedly greatly increases the processing time and cost and reduces the production efficiency.

Detailed implementation manners

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] Please refer to Figures 1 to 3 A wire harness connector mainly includes a cylindrical outer shell 1 and a conductive pin 2. The cylindrical outer shell 1 serves as the main structure of the connector, providing not only mechanical support but also protection. Inside the cylindrical outer shell 1, a connecting part 3 is integrally provided, and the conductive pin 2 is encapsulated inside the connecting part 3 through an injection molding process. This design ensures the stable transmission of current or signals, while improving the reliability and stability of electrical connections.

[0040] The overall shape of the conductive pin 2 is cylindrical, and both ends thereof extend outside the connecting part 3. To optimize the transmission efficiency of current or signals, a plurality of conductive pins 2 are provided, and they are equally angularly distributed relative to the connecting part 3. In the middle of the conductive pin 2, connecting holes 4 are also provided. These connecting holes 4 are located inside the connecting part 3, and the injection molding material can fill them, further enhancing the connection stability between the connecting part 3 and the conductive pin 2.

[0041] At one end of the conductive pin 2, we designed a chamfered corner 5, which not only optimizes the appearance of the pin but also improves its safety during use. At the other end, a through hole 6 along the radial direction and a mounting groove 7 along the axial direction are provided, and the through hole 6 and the mounting groove 7 communicate with each other. Such a design facilitates subsequent connection and fixation with other components.

[0042] On the outer sidewall of the cylindrical housing 1, we added a mounting plate 8, and the mounting plate 8 is provided with mounting holes 9, which enables the wire harness connector to be conveniently connected and fixed to other components through the mounting holes 9.

[0043] In addition, one end of the cylindrical housing 1 is designed as a stepped shape 10, and the length of the conductive pin 2 is less than the length of the cylindrical housing 1. Chamfers 11 are also provided at both ends of the cylindrical housing 1. Such a design not only optimizes the structure of the housing but also facilitates the installation and assembly process.

[0044] Please refer to Figures 1 to 8 To efficiently produce such a wire harness connector, we also provide a special wire harness connector production device. The device includes key components such as a bottom plate 12, a moving mold 13, a fixed mold 14, a vertical plate 15, and an opening and closing mold cylinder 16. The fixed mold 14 and the vertical plate 15 are fixed on the top of the bottom plate 12, and the vertical plate 15 and the fixed mold 14 are connected by four guide rods 17. The moving mold 13 is slidably mounted on the guide rods 17, and an opening and closing mold cylinder 16 is fixed on one side of the vertical plate 15, and the output shaft of the opening and closing mold cylinder 16 is fixedly connected to the moving mold 13. On the fixed mold 14, insertion holes 18 for mounting the conductive pins 2 are provided, and these insertion holes 18 extend into the mold cavity of the fixed mold 14.

[0045] To automatically insert the conductive pins 2 into the insertion holes 18, a feeding device 19 is installed on the bottom plate 12. The feeding device 19 mainly consists of a first mounting seat 20 and a second mounting seat 21, and a rotating shaft 22 is rotatably connected between them through a bearing. At both ends of the rotating shaft 22, convex parts 23 are provided to prevent the conductive pins 2 from slipping. On the sidewall of the rotating shaft 22, accommodation grooves 24 for accommodating the conductive pins 2 are equiangularly arranged between the two convex parts 23, and both ends of these accommodation grooves 24 extend to the ends of the rotating shaft 22.

[0046] Between the first mounting seat 20 and the second mounting seat 21, a hopper 25 for holding the conductive pins 2 is also fixed. The hopper 25 is provided with a discharge port 26, and only one conductive pin 2 can be discharged each time from the discharge port 26. To ensure that the conductive pins 2 can be accurately fed into the insertion holes 18, a pushing device 27 and a driving device 28 are also installed on the bottom plate 12.

[0047] The pushing device 27 is mainly composed of a third mounting seat 29, a pushing cylinder 30, a rotating rod 31 and a push rod 32. The third mounting seat 29 is fixed on the top of the bottom plate 12, and the pushing cylinder 30 is fixed thereon. The output shaft of the pushing cylinder 30 is rotatably connected with the rotating rod 31, and a push rod 32 is fixed at one end of the rotating rod 31 away from the pushing cylinder 30. The push rod 32 is slidably connected in the receiving groove 24, and its diameter is equal to that of the conductive pin 2 to ensure that the conductive pin 2 can be smoothly pushed into the insertion hole 18.

[0048] The driving device 28 is mainly composed of a column 33 and a guide rod 34. The column 33 is fixed on the top of the bottom plate 12, and the guide rod 34 is fixed thereon. A spiral groove 35 and a straight groove 36 are provided on the side wall of the rotating rod 31, and the straight groove 36 communicates with one end of the spiral groove 35. The end of the guide rod 34 is matched with the spiral groove 35 and the straight groove 36 to ensure that the rotating rod 31 can rotate and move along a predetermined track during the pushing process.

[0049] The design of the hopper 25 is also very ingenious. It includes a V-shaped part 37 and an arc-shaped part 38 sleeved on the outer side wall of the rotating shaft 22. The arc-shaped part 38 is in close contact with the side wall of the rotating shaft 22, which plays a role in blocking the receiving groove 24 to ensure that each receiving groove 24 can only accommodate one conductive pin 2.

[0050] In the processing technology of using this wire harness connector production equipment, we adopt the following steps:

[0051] S1: Conveyance of conductive pins. The conductive pins 2 are placed in the hopper 25 in the same direction, and the pushing cylinder 30 is used to push the rotating rod 31 and the push rod 32 to move together. Due to the cooperation of the end of the guide rod 34 with the spiral groove 35 and the straight groove 36, the rotating rod 31 will rotate during the process of moving relative to the bottom plate 12, and then drive the rotating shaft 22 to rotate. Under the action of gravity, each receiving groove 24 will be filled with one conductive pin 2. When the guide rod 34 moves into the straight groove 36, the rotating rod 31 and the rotating shaft 22 stop rotating. As the push rod 32 continues to move forward, the conductive pin 2 in the receiving groove 24 is accurately conveyed into the insertion hole 18.

[0052] S2: Integral injection molding of the cylindrical shell 1, the connecting part 3 and the mounting plate 8. Injection molding operation is carried out by closing the moving mold 13 and the fixed mold 14, so that the cylindrical shell 1, the connecting part 3, the mounting plate 8 and the conductive pin 2 are tightly injection molded together to form a complete wire harness connector.

[0053] S3: Open the mold and take out the wire harness connector. After the injection molding is completed, the mold is opened to take out the finished wire harness connector.

[0054] S4: The pushing cylinder 30 retracts in the reverse direction. Prepare for the next processing.

[0055] S5: Repeat the steps of S1 - S4 for continuous production operations.

[0056] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
