Chassis assembling with Press-in technology

Technics

Assembly and functional description

Traditional flange and bulkhead mounting is increasingly being replaced by the new Press-in technology. Here the connector is pressed into the panel without screwing, providing a form-fit connection. IMS Connector Systems offers this technology for all connector families.

Conditions
The Press-in connectors feature a cylindrical part with special knurling.
The fitting drill holes of the panel are defined depending on the application and type of connector.

Benefits over flange and bulkhead versions
The Press-in technology has several benefits over traditional procedures:

Quick fitting
Economic, material-saving connector housings
No screws or nuts
Perfect self-centering
Good electrical performance

Test adapters
Several applications require a termination test before mounting the connector.
For this purpose, special test adapters are available.
