Electrical connector with spring for missile launch rail

摘要

An electrical connector for testing of missile launch rail is provided. The electrical contacts of the connector move from a rear disengaged position to forward engaged positions via the energy of a compressed spring. The connector base has rail mounts for securing to a missile launch rail. A housing attaches to the base and houses a plunger, an insulator, electrical contacts, and a tube, which move forward and aft as a unit. A knob on a rear tube end enables user to limit the initial impact of the electrical contacts on contact pins or striker points of missile launch rail. The connector can provide electrical connection with launch rail pins as rail pins recede into the missile launch rail. Electrical contact position is governed, in part, by locating pins which ride in a track cut into an outer surface of the tube and move with rotation of an indexing ring.

主权项

1. A method of electrically coupling a spring loaded electrical connector to a missile launch rail, the method comprising:
visually verifying a position of electrical contacts and a plunger in a rear locked position; if not verified, then pulling a tube knob rear ward to an interim locking position and then letting go allowing the connector to reach the rear locked position and then visually verifying the position of the electrical contacts and the plunger in the rear locked position; if verified in the rear locked position, securing a connector rail mount of a base plate into the missile launch rail; aligning the electrical contacts and the plunger of the connector with a receptacle and contact pins of the missile launch rail; grasping the tube knob and pulling backward, allowing an index cylinder to rotate 45 degrees to an unlocking position; maintaining a grasp on the tube knob, permitting forward translation of the tube, the plunger and the electrical contacts to move forward under spring energy to mate with contact pins of the missile launch rail.
