Description

Technical Field

[0001] The invention relates to a connector, in particular to an I-shaped double redundant complementary contact piece, a connector and a processing method thereof. Background Art

[0002] Connectors play a vital role in aerospace and other fields. They are not only the transmission medium of power, but also the important transmission medium of control signals and measurement signals. In order to improve the reliability of system electrical connections and ensure the accurate delivery of power, control signals and measurement signals, most aerospace systems adopt redundant designs to transmit power and signals through two independent lines.

[0003] The power or signal source is usually connected to the receiver through a connector. If the upstream line of one connector in the redundant design is disconnected at the same time as the downstream line of another connector, the power or signal of the system cannot be delivered. Through the reliability block diagram model analysis, it can be seen that some independent units on a single line for power or signal transmission can be equivalently combined to form a virtual unit, which greatly reduces the reliability of the redundant system. If the two redundant lines have multiple connection points, the reliability of the redundant system will be further reduced.

[0133] Step 1.6, by laser welding, install the other two short-circuit connectors 6 on the second wire ends of the two pins 201 respectively;

[0134] Step 1.7, according to actual needs, install the short-circuit 7 between each set of corresponding short-circuit butt joint grooves 6 by laser welding, or do not perform this operation;

[0135] Step 1.8, using an electroplating process, a metal protective layer is plated on the surfaces of the selective jack assembly 3 and the selective pin assembly 4 to complete the processing of the I-shaped double redundant complementary contact pieces;

[0136] Step 2, repeat step 1 twice to obtain two sets of I-shaped double redundant complementary contacts;

[0137] Step 3: Processing I-shaped dual redundant complementary connectors

[0138] Step 3.1, arrange the two selective jack assemblies 3 in a preset order, and then fix them in the third cylinder of the female connector 9 by potting glue;

[0139] Step 3.2, arrange the two selective pin assemblies 4 in a preset order, and then fix them in the first cylinder of the male head 8 by potting glue to obtain an I-shaped double redundant complementary connector, and complete the processing.

[0140] In the two embodiments, the first convex ring and the second convex ring both serve to facilitate fixation with the potting glue, and the third convex ring serves to facilitate taking and placing of the short-circuit component 7 .

[0141] The difference between the above-mentioned embodiment 1 and embodiment 2 is that the structures of the short-circuit piece 5 and the short-circuit connecting groove 6 and the short-circuit 7 are different. If the short-circuit piece 5 is used, the two pins 201 or the socket 101 are welded as one piece during processing, and the structure cannot be changed later. If the short-circuit connecting groove 6 and the short-circuit 7 are used, if the later demand is uncertain during processing, the short-circuit 7 can be not welded first. If there is a short-circuit demand later, the short-circuit 7 can be welded, which greatly improves the flexibility and reduces the processing difficulty.
