3. Challenges:
The electrical connectors on electric vehicles come in various types and forms. Injection-molded housings from different batches are not exactly the same. The sealing stability must be ensured to realize continuous test TAKT on the wire and avoid invalid NG.
4. Solutions:
LANGAN® LA151 series electric vehicle test connector perfectly solves the above mentioned challenges. When the test quick connector is mounted in place, simply give the clamping lever a 90 ° rotation which actuates the seal to expand and seal inner wall of electrical connectors. Thanks to the self-adjusting technology, it is applicable to bigger injection tolerance with better sealing stability. Customized test connectors are available on request with 3D drawings.
5. Applications:
For air tightness leak test of high voltage/low voltage signal electrical connectors on the Battery packs, Microprogrammed Control Unit (MCU), inverter, Power Distribution Unit (PDU), On-Board Charger (OBC) etc.
6. How to customize:
Custom electric vehicle leak test connectors are designed to a specific client's demand to perfectly adapt to testing space, various connection ends and surface conditions with unwavering standard.
