The abbreviation (CA) refers to Cable Attachment and (CC) refers to Captive Connector, which requires a PCB mounted connector. There is no back/side support for the connector, only a front retainer, so there has to be 88mm between the front of the connector flange and the back of the PCB to stop it sliding back, and it needs to be 35mm wide to locate it laterally.
