ILC55 Type Firewall Connectors FRF/FVF Fire wall connectors are designed to meet the requirements of ILC55 and prevent the passage of +9 C (+2 F) flames for 2 minutes. They incorporate the latest sophisticated design imporvements nessary to meet the exacting demands of supersonic flight applications. ome of these features are temerature capabilities to + C (+92 F) for more than hours, lighter weight, small than other ILC55 firewall connectors, and crimp front release contacts. Firewall connectors fulfill the very important application of providing a means to penetrate the engine firewall of military and commercial aircraft with electrical circuits, and still maintain the integrity of the flame barrier requiements of the aircraft firewall. These connectors provide protection against high temperatures, emergency fireretardant conditions, moisture, atmospheric changes, and are resistant to fuels, cleaning agents, coolants, and hydraulic fluids. aterials of connector arrangements are designed to meet the requiremetns of ILC55 Class K connectors. The maximum operating temperature noted for these connectors is the maximum internal hot spot resulting from any combination of electrical load and ambient conditions.

Numerical FR/FRF modifiers are assigned consecutively as needed and there is no significance to numerical order.. The basic FR and FRF connectors were designed for use without ferrules. Ferrules are suggested when undersized wire is used so that the grommet seals will not spread apart (i.e. opened) when the wires are flexed as the wire maybe too stiff for its bend to be completely damped out by the endbell cable clamp. www.ittcannon.com 2

ILC55 Type Firewall Connectors Wire tripping Using proper assembly tools (see page ), strip insulation from end of wire to be crimped. (ee table for proper stripping dimensions.)

Wire insulation must butt against rear of contact. Wire must be visible thru inspection hole. Using 2252/ crimp tool with proper locator, insert wire and contact into locator jaws. queeze tool handle together until ratchet releases. When using CBT 6B crimp tool, follow instructions supplied with tool. Inspect crimped contact to be sure proper crimp has been made. Insertion. lide conduit adapter or clamp bars over wire bundle in proper order for reassembly. 2. lide wired contact into proper insertion tool so that tip of tool butts against contact shoulder.. Inset wired contacts into cavities from rear of insulator until contact "clicks" into retaining clip. slight pull on wire will assure that contact is securely seated. Extraction. fter all contacts are inserted, assemble conduit adapter or clamp bars.. Remove conduit adapter or clamp bars from connector assembly. 2. Using proper extraction tool, insert tool around contact from front of insulator until tool tip butts against contact shoulder. Push plunger to release contact.. Pull wired contact out from rear of insulator.. fter replacing contact, reassemble conduit adapter or cable clamp. www.ittcannon.com 25
