Description

Technical Field

[0001] The present invention relates to the technical field of wiring harness and plug installation, in particular to an electrical wiring harness and plug installation device and process. Background Art

[0002] A wiring harness is a collection of wires and cables. These wires are typically encased in insulation. A plug is an electrical connector used to connect the wiring harness to the device interface. During installation, the insulation on one end of the wiring harness is removed.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 7 , an electrical wiring harness and plug installation device shown in the figure includes a mounting base 1, a notch is opened on the top of the mounting base 1, a cavity is provided in the mounting base 1, and a guide plate 2 is fixed in the notch, a baffle 3 is fixed on the top of the guide plate 2, mounting openings 4 are opened on both sides of the notch, a transmission part 5 for the wires to abut against each other is installed in the mounting opening 4, a through opening 6 connected to the cavity is opened in the notch, a guide part 7 is slidably inserted in the through opening 6; and a driving member 8 installed at the bottom of the mounting base 1, the driving member 8 is used to drive the transmission part 5 to rotate; and a lower pressing plate 9, a pressure block is fixed to the bottom of the lower pressing plate 9, and an adjusting rod 10 for driving the guide part 7 to move upward is fixed at both ends of the lower pressing plate 9, and an adjusting opening 11 for moving the adjusting rod 10 is opened on the mounting base 1;

[0033] In this solution, the guide portion 7 is designed to move the wire upward and against the baffle 3, and the transmission portion 5 drives the wire inward. With the help of the shape of the guide plate 2, the wire is separated outward and respectively plugged into the two terminal pins on the plug. Finally, the pressure block on the lower pressure plate 9 is moved downward to press the terminals, thereby completing the installation between the wire and the plug. During the whole process, the direction of the wire is controlled by the guide portion 7 and the transmission portion 5, so that the wire can be accurately inserted into the plug to avoid docking errors.

[0034] It should be noted that: a person holds the wiring harness and aligns the two wires inside it with the guide plate 2 and inserts them. The front end width of the guide plate 2 is small, so it is easy to separate the two wires. Subsequently, with the help of the guide part 7 and the transmission part 5, the wires can be automatically transmitted.

[0035] For further information, see Figure 4 - Figure 6 and Figure 9 The guide portion 7 includes a guide pad 12, a slide rod 13 fixed to the inner wall of the cavity is slidably inserted in the guide pad 12, and a tension spring 14 fixed to the guide pad 12 and the inner wall of the cavity is sleeved on the outer side of the slide rod 13. A seesaw 15 is rotatably installed in the cavity, one end of the seesaw 15 is in contact with the bottom of the guide pad 12, and the other end is adapted to the adjusting rod 10;

[0036] For further information, see Figure 5 - Figure 8 The conveying portion 5 includes a conveying wheel 16, a rotating rod 17 is fixed in the conveying wheel 16, a moving opening 18 is opened in the mounting opening 4, the rotating rod 17 is slidably inserted in the moving opening 18, and an elastic component 19 is installed in the moving opening 18, which drives the rotating rod 17 to be pushed outward by the elastic component 19;

[0037] Among them, the elastic component 19 includes a push block 20 that is slidably inserted into the movable opening 18 and a sleeve column 21 that is rotatably sleeved on the outside of the rotating rod 17. A push-off spring 22 is fixed between the push block 20 and the sleeve column 21. Through the action of the push-off spring 22, an elastic force is generated between the push block 20 and the sleeve column 21. When the wire just enters between the transmission wheel 16 and the guide plate 2, the transmission wheel 16 can move in the movable opening 18, thereby allowing the wire to enter smoothly. The action of the elastic force makes the transmission wheel 16 more tightly against the outside of the wire, thereby improving the transmission effect.

[0038] Also, see Figure 4 and Figure 9 The driving member 8 includes two driving motors 23 fixed to the bottom of the mounting base 1 through a motor frame, and two driving rods 24 are rotatably installed in the cavity. The output ends of the two driving motors 23 are respectively fixed to the two driving rods 24, and driving wheels 25 are fixed to the outside of the two driving rods 24. Two transmission wheels 27 are rotatably installed in the cavity, and the two transmission wheels 27 are respectively engaged with the outsides of the two driving wheels 25 and are sleeved with synchronous belts 28. A driving wheel 29 engaged with the transmission wheel 27 is fixed to the bottom of the rotating rod 17.

[0039] The principle of using the transmission part 5 and the guide part 7 to transmit the wires in a designated manner: first, the personnel moves the wiring harness to one side of the mounting seat 1, and distributes the two wires inside it at both ends of the guide plate 2 and inserts them. After insertion, the driving motor 23 in the driving member 8 rotates, causing the driving rod 24 to rotate. Under the action of the driving wheel 25, the two driving rods 24 rotate synchronously, and under the action of the synchronous belt 28, the two transmission wheels 27 rotate synchronously. At this time, the transmission wheel 16 and the rotating rod 17 under the action of the elastic component 19 are in an outward pushing state, so that the driving wheel 29 fixed at the bottom of the rotating rod 17 is engaged with the transmission wheel 27, so that the rotation of the transmission wheel 27 can drive the rotation of the driving wheel 29.

[0040] It should be noted that in order to improve the transmission effect of the wire, a guide wheel 33 is rotatably installed in the guide plate 2, and the guide wheel 33 is fixed to the drive rod 24. Through the mutual cooperation between the guide wheel 33 and the transmission wheel 27, the two sides of the wire are synchronously transmitted, thereby improving the transmission effect.

[0041] For further information, see 5 and Figure 6 In order to limit the up and down movement range of the guide pad 12, a limit plate 36 is fixed at the bottom of the guide pad 12, a limit opening 34 is opened on the through opening 6, and a limit block 35 adapted to the limit opening 34 is fixed on the top of the guide pad 12, so that the guide pad 12 can only move within a certain range.

[0042] In this solution, a process for installing an electrical wiring harness and plug includes the following steps:

[0043] S1. Cut the wire harness to equal lengths and remove the insulation layer at the outer end of the wire harness;

[0044] S2, using a conveying device to convey the plug connector to the outside of the mounting seat 1;

[0045] S3. The staff places the wire harness outside the mounting base 1 and conveys the wires to the pin terminals of the plug connector through the guide portion 7 and the conveying portion 5.

[0046] S4. Use the lower pressing plate 9 to press down, driving the pressing block to perform cold pressing on the pin terminals of the plug connector.

[0047] Example 2: Please refer to Figure 6 - Figure 8 This embodiment further explains the first embodiment. The difference lies in that a mounting groove 30 and related components are added to increase the pushing force of the elastic component 19 on the rotating rod 17.

[0048] Specifically, a mounting groove 30 that is interconnected is provided between the movable port 18 and the adjustment port 11, a U-shaped frame 31 is slidably inserted into the mounting groove 30, and a magnetic plate 32 is fixed in the mounting groove 30. The magnetic plate 32 and one end of the U-shaped frame 31 are magnetically attracted to each other, driving the U-shaped frame 31 to move toward the adjustment port 11, and chamfers are provided at both ends of the U-shaped frame 31 that are adapted to the bottom of the adjustment rod 10 and the pushing block 20.

[0049] In this solution, when the adjusting rod 10 moves downward, the U-shaped frame 31 will be driven to move into the moving opening 18, and one end of the U-shaped frame 31 will abut against the pushing block 20, so that the pushing block 20 moves toward the sleeve 21, thereby squeezing and pushing the spring 22, so that the rotating rod 17 and the transmission wheel 16 can move stably outward. After the subsequent adjusting rod 10 moves upward, the suction force generated by the magnetic plate 32 causes the U-shaped frame 31 to move toward the adjusting opening 11, so that it no longer contacts the pushing block 20, thereby facilitating the insertion of the wire.

[0050] Example 3: Please refer to Figure 1 - Figure 4 This embodiment further explains other embodiments, and the difference lies in the development of one specific embodiment of the adjustment rod 10.

[0051] Specifically, the adjusting rod 10 includes an inner rod 37 and an outer rod 38, and the inner rod 37 and the outer rod 38 are plugged into each other. An extrusion spring 26 is fixed between the inner rod 37 and the outer rod 38, and the inner rod 37 and the adjusting port 11 are plugged into each other. The bottom of the inner rod 37 is chamfered. The adjusting rod 10 designed in this scheme has a certain elasticity. After it is pressed down, it can enter the adjusting port 11 through the inner rod 37 and lift the rocker 15, so that the guide pad 12 moves up, and the pressure block does not squeeze the pin end in the plug. After the wire guidance is completed, it continues to move downward through the lower pressure plate 9, driving the pressure block to cold press the end.
