A time delay mechanism force fuze wherein the mechanism comprising an encoder ring, having an inner surface with a predetermined mask pattern of lands and grooves, is locked by a spring lock exerting pressure in a radially outward motion, thus enhanced when the fuze is exposed to the influence of dynamic forces from a gun, is shown. The spring lock cooperates with a lock pin such that a radially inward deflection of the lock pin deflects the spring lock so that the encoder ring with a reaction surface is unlocked and can be fully rotated by a setting collar acting through a detent spring on the reaction surface. If the encoder ring is locked, the detent spring is deflected over the reaction surface of the encoder ring when the setting collar is rotated, thereby preventing the encoder ring from being changed. A plurality of actuators, which determines a digital word that represents a length of time for a time delay in a digital timing circuit for the fuze, is actuated by the predetermined mask pattern. The digital word is changed by rotating the setting collar while the encoder ring is unlocked.

A connector is provided for electrically and coaxially coupling a cable to a male plug assembly. The connector includes a coupling collar adapted to receive the cable therein and to selectively receive the male plug assembly in mating engagement with the cable. The connector also includes a housing adapted to movably support the coupling collar such that the coupling collar is freely movable in a substantially orthogonal direction relative to the coaxial direction to facilitate the mating engagement. A spring is provided to urge the connector towards mating engagement. The coupling collar is generally cylindrical and includes a flange which extends outwardly from the periphery of the collar in the substantially orthogonal direction. The flange is slidably supported within a substantially planar centering washer such that the flange is adapted to move in the substantially orthogonal direction within the centering washer. The centering washer is concentrically and slidably disposed within an elongated bore of the stationary housing and is supported within the bore by the spring.

A quick connect and quick disconnect connector assembly for connecting with a mating connector comprises a body and an engagement means. A retaining means is provided for securing the engagement means to the body. The engagement means includes an inner gripping member that is telescopically received in an outer actuation member. The inner gripping member has an outer wall surface that is formed with a first ramp portion and the outer actuation member has an inner wall surface that is formed with a second ramp portion, the first ramp portion being complementary to the second ramp portion. The first ramp portion of the outer wall surface of the inner gripping member is configured to interferingly engage and cooperate with the second ramp portion of the inner wall surface of the outer actuator member. The first ramp portion of the inner gripping member is formed with resilient fingers that are movable between a relaxed state and an inwardly urged state. The resilient fingers of the inner gripping member are moved inwardly from the relaxed state to the inwardly urged state for gripping engagement with the complementary connector when the second ramp portion is urged against the first ramp portion.

A pneumatic planar probe for electrical transmission lines containing single or multiple contacts is provided for planar termination to a receiving structure. The pneumatic planar probe includes a header, a first probe body and a second probe body that are arranged as an extension of a transmission line having a center conductor and an outer conductor, the first probe body and second probe body extending the outer conductor and center conductor, respectively. The first probe body and second probe body are received in the header. The second probe body is supported in a dielectric body, the second probe body and dielectric body being concentrically slidably mounted in the first probe body. A first probe body interface at a free end of the first probe body is configured to contact a ground planar surface of the receiving structure. A second probe body interface at a free end of the second probe body is configured to contact a signal planar surface of the receiving structure. A first annular volume is pressurized to urge the first probe body interface to press against and become in pressurized contact with the ground planar surface of the receiving structure. A second annular volume is pressurized to urge the second probe body interface to press against and become in pressurized contact with the signal planar surface of the receiving structure. When the first probe body interface is in pressurized contact with the ground planar surface and the second probe body is in pressurized contact with the signal planar surface, the planar probe is in planar termination with the receiving structure.

A fastener assembly is shown including a cylindrical support structure with a bore provided partially therein, the bore having a wall surface with a slot, and a bushing, disposed within the bore of the cylindrical support structure, having an end and an outer surface with a slot therein. The bushing further includes a bore with a first portion having a first diameter and a second portion having a second different diameter, the bushing also having a pair of tangs extending from the end. The fastener assembly further includes a nut, partially disposed within the second portion of the bore of the bushing, the nut having an outer surface with a pair of lugs disposed on the outer surface to engage the pair of tangs of the bushing and a pin disposed juxtapositional the slot of the wall surface of the cylindrical support structure and juxtapositional the slot of the bushing. The fastener assembly still further includes a pin disposed juxtapositional the slot of the wall surface of the cylindrical support structure and juxtapositional the slot of the bushing. With such an arrangement, a fastener assembly is provided in which a forward shell section and an aft shell can be interconnected independent of the cylindrical support structure, thus maintaining circularity of airframe components and minimizing circular distortion.

A connector assembly for interconnection with a mating connector includes a body, a locking nut, and a restraining element. The restraining element rotatably secures the locking nut on the body of the connector assembly. The restraining element can have an annular configuration and be elastically deformable. When this configuration is utilized, the body typically includes a ramp with a groove in juxtaposition thereto. The ramp facilitates both deformation and placement of the restraining element in the groove of the body. Alternatively, the restraining element can have a substantially rigid, tubular configuration and include a flange sized and shaped to engage a portion of the locking nut. This later configuration of the restraining element is designed to be interferingly positioned on the body of the assembly. Also disclosed is a tubular tool element configured to be capable of exerting a substantially equal force upon the restraining element during manufacture of the disclosed connector assembly. The tool element is utilized to align and secure the restraining element on the body during the manufacturing process.

A cable connecting system for interconnection with a mating connector includes a connecting element, a first securing element, and a second securing element. The first securing element is rotatably mounted to the connector and the second securing member is rotatably mounted to the first securing element. In operation, the first and second securing elements are first threaded onto a receiving section of the mating connector. Once fully positioned on the receiving section of the mating connector, torque is applied in a conventional direction to the first securing element to secure the connecting element to the mating connector. Then, torque is applied in a counter direction to the second securing element to lock the first and second securing elements. The cable connecting system and the method of interconnection utilizing the cable connecting system is reversible so as to allow repeated connection and disconnection of various assemblies of cable assemblies.
