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.

The wiring harness provided herein affords adjustability of the relative orientation between the connecting cable and its interface connector in real time, during field applications. The harness rotates to accommodate varying access angles to the desired test point connector. A cable conduit of the harness can be adjusted vertically relative to the axis of its interface connector, as well. Cable wire integrity is maintained during manipulations of the cable conduit relative to the harness electrical connector and stress on the wires is minimized. The harness can be sealed from moisture and environmental factors. The harness can provide shielding from electromagnetic interference for the cabling housed therein. The present harness is well suited for service in high heat environments in, for example, testing of aircraft systems. A cylinder receives the cabling conduit and swivels within a slotted backshell. Slot configuration can limit the translation of the cable conduit.

Rotatable wiring harness for cable and method

Repeated inserting, tightening, loosening, and removing of external threads to internal threads can increase the likelihood of cross threading and thread damage. A spring loaded gear bolt assembly, which promotes alignment of mating threads before applying torque, is described. A spring is disposed on the back end of a bolt shaft to promote alignment of lead mating threads before twisting to engage external to internal threads. A gear chain translates a single hand rotation to thread two bolts into respective affixed internal threaded holes, simultaneously. A spring loaded gear bolt assembly and method described herein promote increased thread life and ease of use ease for test plate securing. Efficient single handed manipulation of multiple bolts simultaneously can be achieved using a test plate assembly, which included spring loaded gear bolt assemblies, as described herein. Applications of a spring loaded gear bolt include infrared adapter test plate assemblies.

An anchoredmale electrical connector is provided. A stationary housingis combined with a coupling ringto form an outer housing. An internal plungeris housed in and spans the length of the outer housing. The stationary housingmounts onto an anchoring surface via an anchor mount, while the coupling ringis free to rotate about the internal plunger. The coupling ring is rotated via a hand grasp. The coupling ring rotationtranslates into forward and aft movement of the pin assembly. The connector provides forward-and backward stops-for limiting pin insertion and extraction moves to desired distances. Rotation via triple start threadsreadily overcomes insertion and extraction resistance of a bulky multi-pin assemblyand provides a smooth and controlled electrical connection. The connector may be sized to meet multi-pin connector needs or military standards.

The connector provides forward and backward stops for limiting pin insertion and extraction moves to desired distances. Rotation via triple-start threads readily overcomes insertion and extraction resistance of a bulky multi-pin assembly and provides a smooth and controlled electrical connection. The size of the connector approaches that of a small conventional military standard 38999 series III connector.

A connector for a weapons test set circuit has a case with an open end and electrical conductors extending from the open end into and through the case. The connector is designed to connect to a rail and has coupling legs for this purpose. Each coupling leg has a base portion located in the case and an extension portion that extends out of the case and diverges from the other extension portion. The base portions can move toward each other or apart from each other along guides and are biased in the apart position. Buttons extend from the base portions out of the case; an operator depresses the buttons to converge the legs to allow insertion or removal of the connector from the rail. Releasing the buttons causes the legs to move to the apart position.

The invention is directed to apparatus for making an accessible connection between a cable and a coupler, wherein electrical wires extend between the cable and the coupler. A removable stop is provided which is adapted to engage the cable and the coupler to hold the cable and the coupler apart to form a gap therebetween wherein the electrical wires extend between the cable and the coupler by way of the gap. A sleeve is provided which is movable between a closed position wherein the sleeve engages the cable and the coupler and surrounds the wires and the stop, and an open position wherein the gap is exposed and the wires are accessible. Also provided is a fastening mechanism for removably fastening the sleeve in the closed position and for allowing the sleeve to be moved from the closed position to the open position.

The reed employs two spaced apart cylinders with slots in their outer surfaces. The slots extend around the axis of each cylinder a given distance. The slots of each cylinder flare out from each other from one edge to an opposite edge. Dents are supported for movement between the two cylinders and have guides located in the slots of each cylinder. The two cylinders can be rotated together in one direction or in an opposite direction for causing the slots to move the guides and hence the dents apart or together to obtain changes in the width of the fabric along the warp direction. This change in width will cause the warp density to vary along the length of the fabric while maintaining continuous warp yarn. This feature also allows warp strands of different cross-section to be woven.

The fire extinguisher includes a container filled with a fire extinguishing liquid and having a normally closed main outlet and support structure extending through an opening of the container wall. A compressed gas cartridge located in the container is supported by the support structure. The support structure has an opening formed therethrough which leads to the end of the compressed gas cartridge. A plunger, an explosive charge, and a heat sensitive fuse, the latter of which has a portion is exposed to the exterior of the container, are located in the opening of the support structure. In the presence of high temperature, the fuse causes the explosive charge to explode and force the plunger to rupture the cartridge which release the gas into the liquid in the container by way of a normally closed gas outlet formed through the wall of the support structure. This causes the liquid to be forced out of the container by way of the normally closed main outlet. In another embodiment, the fire extinguishing material in the container may be a powder.
