3 Selection and requirements of line beam connection positions

The position of the line beam connection generally does not have special regulations in the online beam 2D drawings. The relatively strict drawings only specify the area where the contact is located. However, according to practical experience, design contacts should be avoided in the online beam large song area, motion part, branch point, inside the rubber parts, small branches, flowing water area, and no bandaging protection areas. In general, the design position of the contact is relatively loose. As a manufacturer of wire beam, how to choose the position of the connection is very important. It not only affects the cost of the wiring beam, but also the quality of the beam product. Unreasonable designs will be thickened, wasting the raw materials of wire beam wires, and increasing the quality of the wiring beam; at the same time, it is not conducive to the wiring of the wiring beam, causing subsequent hidden dangers such as difficulty and interference. So how can the contact location be selected to achieve the best results?

According to practical experience, the simplest and practical method for finding the contact position is the branch of the branch. The so -called branch interchange method refers to the starting point of a set of wires that must be hinged based on the branch of each line number (that is, the branch of each line number). Nearby (because the contacts cannot be at the intersection point) are the most ideal contact position. The closer to the intersection point, the more capable of saving the wire. As shown in Figure 5, the branch number 1 is located 1, the branch number 1A is located 2, the branch number 1b branch 3, and the 4 or 4 branch of the line number 1c to meet the most electricity line. However, the branch point cannot be designed, so the contact should be selected appropriately near the branch point. You can choose a hinge method and contact location according to the size of the line diameter of each line and subsequent assembly.

In special circumstances, there may be two or more at the intersection of the branch. There are two interchange points of the branch shown in Figure 6. At this time, the intersection point 1 and the intersection point 2 should be analyzed.

The number of branches on the right of two on the right of the junction point should be selected near the right side of the intersection point 1, and otherwise, it should be selected near the left side of the intersection point 2. If the number of branches on both sides of the two intersection points is equal, the contact should be selected between the two associations. If the distance between the two intersection points is relatively long, you can consider the double -point hinge, that is, select 1 contact near the right side of the intersection point, and select the second contact near the left side of the intersection point to minimize the wires as much as possible to minimize the wires of the wires. length. The double -contact hinge method is shown in Figure 7.

The 1C line number is the public line, and the 1B line number hinges on the 1C line. Compared with a connection with this design, the wire length of the 1B line number contact 1 and the connection 2 can be saved. However, when designing dual contact, pay attention to the current load capacity of the 1C number of the public load line.

Under normal circumstances, it is not recommended to have multiple hinges, because the more contact, the relatively worse the safety performance of the circuit. Therefore, when the single -connection point is large or can save more wires, the double -point hinge can be considered to avoid excessive contact and save wires. According to experience, the number of entire lines of the entire car lines is about 70 groups. If you can correctly select the contact location, you can reduce the cost of the raw material of the wire by about 2%. It can be said that the connection location is correctly selected, and it has a great role in slowing the thickening of the wire beam, optimizing assembly, and reducing costs.
