MIL-C-5015 Firewall Connectors MS-K firewall connectors have met and are qualified to the fireproof test of MIL-C-5015. This test requires that a connector mounted to a firewall will continure to operate for 5 minutes in case of fire and MS-K prevent the passage of flame for 20 minutes. These connectors are not environmentally sealed but operate continuously at temperature up to +177˚C (+350˚F). MS-K connectors have crimp type con- tacts; thermocouple contacts must be orderd separately and are solder type unless otherwise requested on order. Cavities that will contain the thermocouple contacts and contact material must be specified when ordering.

Remove Formica retaining ring (or the ceramic retaining ring) from contact (Figure 1). 2. Crimp contact to wire. 3. Slip endbell (or junction shell), retaining ring, and washer over wire bundle. 4. Push contact thru rear insulator. (Contact should extend sufficiently to accomplish Step 5.) 5. Attach Formica retaining ring onto the contact (see Figure 1). 6. Seat each contact securely in rear insulator. 7. Assemble front insulator on engaging end of contact. 8. Slide insulator assembly into hardware. 9. Slide washer and insulator retaining ring into place, making sure that insulator retaining is fully seated in groove. 10. Slide endbell or junction shell down wire bundle and attach to shell (or barrel).

However, the formica ring must be removed if using the crimp tools listed below. When using the MS3191-1 (or CCT-1612) crimp tool with property locator, both the ceramic or formica retaining ring for sizes 16 and 12 contacts must be removed. For sizes 8, 4, and 0 contacts, the ceramic or formica retaining rings must be removed before crimping.
