We conduct two key sealing tests on finished wire harnesses:

1. Sealing performance of rubber sleeve

2. Air tightness of the wiring harness body

This link is a required inspection after the wiring harness is assembled, aiming to ensure the waterproof and electrical safety of the product in subsequent use.The test pressure is generally 40kPa。

Detection Difficulties

1. It is difficult to seal both ends of the wire harness: The two ends of the finished wire harness are connected to plugs or terminals of different specifications, which need to be effectively sealed during testing to avoid damage.

2. Irregular shape of the wire harness: The wire harness has many branches and complex directions, making it difficult to form a stable and uniform sealing cavity, which puts forward higher requirements for fixture design and sealing solutions.

solution

Based on the characteristics of the customer's products and combined with future automated production needs, the high-precision HD-28 Ingenuity series air tightness detector can be recommended. The specific solutions are as follows:

1. Detection method: Using the finished product overall detection method, sealing rings and sealants are used at both ends of the wire harness to achieve reliable sealing.

2. Core configuration: Through customized fixtures and test platforms, the wire harness rubber sleeve and body are uniformly pressure tested to accurately determine whether their air-tightness performance meets the standard.
