Abstract: An electrical connector (16) is arranged to releasably receive a pair of conductors (22, 24) and electrically interconnecting the conductors to the terminals (30) of an acoustical speaker (14). The connector includes an insulating housing (36) and a single button (38) in sliding engagement with the housing (36). The button is slidable between a first position (42) where the conductors are held within the connector and electrically interconnected to the speaker terminals (30) and a second position (46) where the conductors (22, 24) can be inserted into the connector or removed therefrom. A pair of contact members (52, 54) are disposed in a cavity (48, 50) within the housing (36). Each contact member includes a tail (28) extending therefrom through an opening (176) in the housing and is electrically interconnected to one of the terminals via a lead (32).

Abstract: A clamp for an electrical cable which is particularly useful for fixing an electrical cable to a railway car truck. The clamp has an arched segment of a rigid sheet material which has a concave face, a convex face, opposed side flanks and open forward and rearward ends. The concave face and side flanks define an elongated concavity therebetween. An arcuate transition segment extends from each flank of the arched segment and connect to one of a pair of opposed flat wing segments. Each arcuate transition segment has at least one opening therethrough. Several detents project from the concave face into the concavity. A cincture such as a steel band extends through at least one opening in each arcuate transition segment and the opposite ends of the cincture are attached together.

Abstract: An air pressure actuated stop assembly (50) is disposed in at least one of first and second rotatably engaging housings of a coupling assembly (10), the housings (14) being affixed to ends of respective associated hoses 70) to complete an air passageway (24) therebetween when coupled. Each housing (14) has a portion with an exterior surface adjacent an interior surface of a complementary portion of the other housing (14) and rotatably slidable therealong during coupling and uncoupling of the assembly (10). The stop assembly (50) includes a spring biased pin (52) that moves when actuated by air pressure in the air brake hose (70) to a position to obstruct the path traveled by the portion of the opposite housing (14) in a direction uncoupling the two housings (14) thereby preventing rotational uncoupling of the housings (14) when the air brake system is pressurized. The pin (52) is automatically retracted when the air pressure is released thus permitting the housings (14) to be uncoupled.

Abstract: An electrical connector (20) includes a dielectric housing (22) having a mating face (24) and a pair of contacts (44,54) disposed therein. Each contact (44,54) has a contact section (46,56) exposed at the mating face (24). The first contact section (46) is associated with a forwardly extending shroud (26) spaced from and circumscribing the first contact section (46). The second contact section (56) is associated with a forwardly extending silo (28) closely surrounding the second contact section (56). The second contact section (56) is complementary to the first contact section (46) and the silo (28) is complementary to the shroud (26), whereby the connector mating face (24) is hermaphroditic.

Abstract: A pivotable connector assembly includes first and second matable connectors (20, 20) adapted to be brought into mated engagement by rotating the connectors in a first angular direction about a center of pivoting, and adapted to be disengaged by rotating the connectors in an opposite second angular direction about the center of pivoting. Each connector (20) includes a housing (22) having at least one contact having an arcuate section mounted therein. One of the contacts (96) is rigidly mounted within its respective connector housing and the other of the contacts (60) is resiliently mounted within its respective connector housing such that upon mating of the first and second connectors (20, 20) the arcuate section of the resiliently mounted contact (60) is engaged by the arcuate section of the rigidly mounted contact (96) along an elongate mating path and laterally deflected therefrom under bias.

Abstract: A right angle electrical connector (20) includes a housing (22) having a mating face (24), an assembly face (26) opposed from the mating face (24) and adapted to receive at least one electrical contact (50) therein, and a third face (28); at least one contact-receiving passageway (30) extending from the assembly face (26) to the mating face (24), and a contact receiving slot (32) open to the third face (28) and to the assembly face (26). Each electrical contact (50) includes a first connecting portion (52) for electrical engagement with a complementary connector, a second connecting portion (54) extending from the third face (28) and outwardly from the housing (22) for electrical connection to an electrical article and a retention section (56) associated with a cooperable housing channel (36).
