With the improvement of consumption levels, both consumers and producers have higher requirements for product quality.The sealing requirements of wires are also constantly increasing. In order to obtain the best performance of wire products, manufacturers often perform sealing testing on wires. However, different types of wires have different requirements for sealing testing. In particular, wires with multi-wire connections are difficult to conduct sealing testing.As a well-known sealing testing and production expert, Hairis Technology has made many achievements in sealing testing of wire rods.

So, this time we will share a number of different models of multi-wire connector wire sealing testing cases for your reference.

one,Wire shape analysis

1. The appearance characteristics of the wire connector of the multi-wire connector: the coating of the long wire is fixed with a metal ring, and the upper connection of the metal ring is divided into two or more wire connectors to connect to the connection holes of different wire connectors; the wires are scattered among themselves, and the wire connector is an irregular rectangular parallelepiped, which is unfavorable for sealing detection;

2. Characteristics of the appearance of two-wire and three-wire wires: the overall shape is an irregular rectangle. Three or two wires are connected to the connectors at both ends. The butt end is fixed with a holder, and the whole is protected with waterproof coating. The irregular shape is difficult to seal during inspection, which is detrimental to inspection.

one,Breakthrough in Difficulties in Wire Sealing Detection of Multi-Wire Connectors

1. For the shape of multi-wire connectors, Hairuis has special grinding tools to hold them. The connectors are placed in the mold and stuck just right. For multi-wire cases, special grooves are also made for packaging. This facilitates the upper and lower closure of the mold during inspection. When inflating the internal body, it can avoid gas leakage and lead to numerical errors.

2. Hairis Technology has also prepared a special mold for the multiple wires that are connected first. The mold has special grooves for two or three wires, and special grooves are also made for the lower connector.This will help the mold to close up and down during inspection, forming a closed inspection environment and avoiding leakage when inflating the inner body during inspection, which is beneficial to inspection.

During detection, the instrument will inflate the mold.If the wire connector is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined whether the wire connector is leaking, and the instrument test result will also show NG, which means the air tightness test failed.If the tested wire connector does not leak, the gas in the tooling mold will be in a constant state after inflation. The pressure value and leakage value displayed on the instrument are also stable. The instrument test result will display OK, indicating that the air tightness test has passed.
