[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] The wire harness wiring system of this utility model, such as Figures 1 to 4 As shown, the system includes multiple wire compartments 2, each with a compartment opening 201 and a corresponding door 21. Each compartment opening 201 has a door 21 for opening or closing. Each door 21 is equipped with a door opening / closing actuator, which opens or closes the door. For example, the door opening / closing actuator can be a cylinder, motor, or electromagnet combined with a spring. The wiring harness system of this invention also includes a connector carrier 3, which has multiple positioning grooves 301 for accommodating connectors 99. The shape of the positioning grooves 301 matches the shape of the connector 99, allowing the connector 99 to be easily inserted into the positioning grooves 301 from top to bottom. The positioning grooves 301 prevent the connector 99 from rotating or shifting horizontally. Figure 3 As shown, the connector carrier 3 is equipped with hole position indicator lights 31 for the wiring holes 991 corresponding to the connector 99. The hole position indicator lights 31 can be light-emitting diodes (red light). The hole position indicator lights 31 are arranged in an array, that is, each positioning groove 301 corresponds to one array of hole position indicator lights 31. The relative arrangement of each wiring hole 991 on the connector 99 that is adapted to the positioning groove 301 is consistent with the hole position indicator lights 31 in the corresponding array. The hole position indicator lights 31 are respectively located on one side of the positioning groove 301. For example, the above-mentioned array of hole position indicator lights 31 can be located on the rear side or the right rear side of the corresponding positioning groove 301. The wiring harness wiring system of this utility model also includes a control system, which controls the opening and closing driver of the connection compartment door and the hole position indicator lights 31.

[0024] The following is a brief explanation of the working principle of the wire harness wiring system of this utility model: Each wire compartment 2 contains a corresponding wire 98. The specifications and color of the wire 98 can be marked on the compartment door 21. Connectors 99 are then placed into their corresponding positioning grooves 301. The control system opens the door 21 of the first wire compartment 2 according to the program settings. Specifically, the control system controls the aforementioned door opening / closing driver to open the door 21 (keeping the other wire compartments 2 closed). The control system also controls the indicator light 31 corresponding to the first positioning groove 301 to illuminate (keeping all other indicator lights 31 off). The operator then pulls out one end of the wire 98 from the opened wire compartment 2, such as... Figure 3 As shown, the operator inserts one end of the wire 98 into the wiring hole 991 corresponding to the illuminated hole position indicator light 31. For example, the connector 99 has three rows and six columns of wiring holes 991. Correspondingly, the array of hole position indicator lights 31 includes three rows and six columns of hole position indicator lights 31. When a hole position indicator light 31 is lit, the arrangement of the illuminated hole position indicator light 31 in the array indicates to the operator that the corresponding wiring hole 991 on the connector 99 has been located. Afterwards, the control system controls the hole position indicator light 31 corresponding to the first positioning groove 301 to turn off. Next, the control system controls the indicator light 31 corresponding to the second positioning groove 301 to light up. The operator inserts the other end of the wire 98 into the connector 99 in the second positioning groove 301. The control system then controls the indicator light 31 corresponding to the second positioning groove 301 to turn off. At the same time, the control system controls the first wire compartment 2 to close. After that, the control system controls the second wire compartment 2 to open according to the program settings. At the same time, the control system controls the next indicator light 31 corresponding to the first positioning groove 301 to light up, and so on. As can be seen from the above, the control system only opens the correct wire compartment 2, preventing the operator from picking up the wrong wire 98. Furthermore, the control system uses the hole position indicator light 31 to guide the operator to insert the end of the wire 98 into the correct wiring hole 991, preventing the operator from inserting it into the wrong hole. This also allows the operator to quickly locate the correct connector 99 based on the illumination of the hole position indicator light 31, thus significantly reducing the time the operator spends searching for the wire 98, connector 99, and wiring hole 991. This promotes orderly wiring of the wire harness, significantly improves production efficiency, and greatly reduces the error rate, thereby improving the product quality of the wire harness. Since the wires 99 are stored in their respective wire compartments 2, and the compartment doors 21 are opened for a short time, it prevents significant dust accumulation on the wires 99 and avoids chaotic material management.

[0025] Furthermore, such as Figure 4As shown, the wire compartment 2 includes a rectangular tube compartment 20, meaning the rectangular tube compartment 20 is a rectangular tubular structure. Therefore, the wire 98 can be placed roughly straight within the rectangular tube compartment 20. The rectangular tube compartment 20 can be made of aluminum rectangular tubing, making the material readily available and the cost low. Figure 1 and Figure 2 As shown, the rectangular tube compartment 20 extends in the front-to-back direction, with the compartment opening 201 formed at the front end. The rear end of the rectangular tube compartment 20 can be closed with a cover plate. The wire grid compartments 2 are arranged in the vertical and horizontal directions, so that when viewed from front to back, the compartment openings 201 are distributed in a rectangular array, making it convenient for the operator to quickly see the open compartment door 21 and easily pull the wire 98 forward from the rectangular tube compartment 20. The wire harness wiring system also includes a bracket 1, which is made of aluminum profile splicing. The wire grid compartments 2 are set on the bracket 1. Adjacent rectangular tube compartments 20 on the same layer can be connected in the horizontal direction to facilitate the arrangement of more rectangular tube compartments 20 in a certain space. The rectangular tube compartments 20 on adjacent layers are separated by aluminum profiles.

[0026] Furthermore, such as Figure 1 As shown, the connector platform 3 is located on the lower front side of the bottom wire grid compartment 2, thus preventing the connector platform 3 from obstructing the wire grid compartment 2. The rear end of the connector platform 3 is fitted with the connecting bracket 1 by corresponding screws.

[0027] Furthermore, such as Figure 1 and Figure 4 As shown, the opening 201 is inclined at the front and upward at the back, meaning that the lower edge of the opening 201 is located in front of the upper edge of the opening 201. When cutting the aluminum rectangular tube to form the opening 201, the saw blade is at approximately a 45-degree angle to the aluminum rectangular tube. Therefore, when the opening 201 is opened, the operator can look at the opening 201 from the rear and downward, making the front end of the rectangular tube compartment 20 more visible. This makes it easier for the operator to see the wire 98 inside the rectangular tube compartment 20, and also makes it easier for the operator to reach their fingers into the front end of the rectangular tube compartment 20 from the rear and downward.

[0028] Furthermore, such as Figure 1 As shown, the openings 201 are set back layer by layer from bottom to top. That is to say, the upper opening 201 is located behind the adjacent lower opening 201. This can prevent the upper rectangular tube body 20 from blocking the opening 201 of the lower rectangular tube body 20. Combined with the inclined setting of the openings 201 with the front lower and the back higher, it is more convenient for the operator to observe and operate to retrieve the wire 98.

[0029] Furthermore, the door 21 is a transparent door, which can be made of acrylic. So when the door 21 is closed, the operator can also observe the inside of the rectangular tube chamber 20 through the door 21. If the inside of the rectangular tube chamber 20 is found to be empty, the wire 98 can be added in time.

[0030] Furthermore, the upper end of the door 21 is hinged to the upper end of the opening 201, thus allowing the door 21 to swing up and down. When the door 21 swings upward to open, since the wire 98 is stacked inside the lower end of the rectangular tube body 20, when the operator pulls the wire 98 forward, the wire 98 will not touch the door 21, thus preventing the door 21 from obstructing or scratching the wire 98.

[0031] Furthermore, such as Figure 4 As shown, the door opening and closing actuator is a cylinder 22, which is located on the upper side of the rectangular tube compartment 20. The cylinder 22 drives the door 21. Compared with using a stepper motor to drive the door 21 to swing, the cylinder 22 has the advantages of lower cost and easier control and maintenance. Specifically, as shown... Figure 4 As shown, the rear end of the first connecting rod 23 is hinged to the piston rod of the cylinder 22, the front end of the first connecting rod 23 is hinged to the rear end of the second connecting rod 24, and the front end of the second connecting rod 24 is hinged to the door 21. Thus, when the piston rod of the cylinder 22 extends forward, the door 21 is lowered, and when the piston rod of the cylinder 22 retracts backward, the piston rod of the cylinder 22 pulls up the door 21 through the first connecting rod 23 and the second connecting rod 24.

[0032] Furthermore, the positioning grooves 301 are distributed in the left-right direction, such as... Figure 1 and Figure 2 As shown, the positioning grooves 301 can be distributed along the front and back directions, which helps to reduce the width of the connector platform 3 in the front and back directions. The operator can stand in front of the bracket 1 to operate the wiring. Since the connector platform 3 is smaller in the front and back directions, the operator's hand can easily reach the position of the opening 201.

[0033] Furthermore, such as Figure 5As shown, the connector carrier 3 is slidably connected to a slide block 30. The slide block 30 can be made of nylon. Specifically, the connector carrier 3 has a sliding hole, and the slide block 30 is fitted into the sliding hole. A positioning groove 301 is formed in the corresponding slide block 30. That is to say, each slide block 30 has only one positioning groove 301. Thus, the connector 99 is actually placed into the slide block 30. The slide block 30 is provided with a stop to prevent the connector 99 from moving upward relative to the slide block 30. The stop only takes effect after the connector 99 is placed into the positioning groove 301. For example, the stop can be a spring-loaded assembly 36. The spring-loaded assembly 36 includes a sliding buckle and an extension spring. The sliding direction of the sliding buckle is perpendicular to the direction in which the connector 99 is inserted into the positioning groove 301. One end of the extension spring contacts the sliding buckle. The operator presses the connector 99 into the positioning groove 301. At time 01, the lower end of connector 99 pushes the guide chamfer of the sliding buckle, thereby pushing the sliding buckle outward (relative to the positioning groove 301). When connector 99 is inserted into the positioning groove 301, the sliding buckle extends inward by the elastic restoring force of the aforementioned extension spring, thereby fastening the sliding buckle to the upper side of the upper edge of connector 99. The slide 30 is correspondingly provided with a micro switch 32 that can be triggered by the downward movement of the slide 30. Specifically, the micro switch 32 is located on the corresponding lower side of the bottom of the slide 30. The slide 30 is connected to a return spring 33 for pulling the slide 30 downward to reset. For example, the return spring 33 is a compression spring. A pull rod 35 is installed at the bottom of the slide 30, and the pull rod passes through the base plate 34. The return spring 33 is located between the lower side of the base plate 34 and the head of the lower end of the pull rod 35. The control system is electrically connected to the micro switch 32. Figure 5 As shown, the elastic restoring force of the return spring 33 pulls the slide 30 downward, causing the flange at the upper end of the slide 30 to abut against the step of the orifice of the aforementioned sliding hole. At this time, the bottom of the slide 30 triggers the micro switch 32. After the operator inserts the end of the wire 98 into the wiring hole 991 of the connector 99, the operator pulls the wire 98 upward. If the wire 98 is well connected to the terminal in the wiring hole 991, the wire 98 will pull the connector 99 and the slide 30 together, causing the slide 30 to disengage from the micro switch 32. This disconnects the micro switch 32, and the control system waits for the micro switch to open. Upon receiving the disconnect signal from switch 32, the control system determines that the connection between wire 98 and connector 99 is sufficiently secure. The operator then releases wire 98, and return spring 33 pulls slide 30 and connector 99 downwards to reset. The bottom of slide 30 returns to its original position, triggering microswitch 32. The control system then executes subsequent steps based on the activation signal from microswitch 32. In other words, the operator must perform the above-mentioned pull-down action each time they insert the end of wire 98 into the corresponding wiring hole 991, thereby improving the yield rate of the wire harness and enhancing the product quality. After the wire harness wiring assembly is complete, the connector 99 is removed from the positioning groove 301 by using a finger to open the sliding latch.
