A self contained circuit board and housing therefore adapted to be positioned within a telephone network interface housing in which provision is made for variance in the dimensions of a pair of retaining slots in the interface housing of different manufacture. The circuit board housing includes a pair of oppositely disposed side walls, each having a laterally extending flange include a resilient component which flexed to accommodate for differences in clearances between the retaining slots.

Maintenance termination unit circuit structure

An improved surge protection unit suitable for use with Western Electric Type 66 blocks, having provision for grounding of the individual subscriber circuit at the block location is disclosed.

Grounded surge protection unit for telephone subscriber circuits

A moulded resilient sealing device adapted to close the exposed opening in a telephone subscriber jack to prevent entry of moisture, vermin and the like. The device includes a cap-like body having a continuous peripheral edge which contacts a planar surface surrounding the plug opening, and a smaller opening at an opposite end thereof which resiliently clamps a flattened cable leading to subscriber equipment, such as a telephone handset at one end and a corresponding plug engaging jack at an opposite end. The opening is shiftable along the cable to increase the resilient force applied to the peripheral edge. The edge is also reinforced along one rectilinear side to prevent distortion by contact with the release lever of the plug, and accomodate for commerical manufacturing tolerances encountered in jacks of different manufacture.

Resilient sealing device for telephone subscriber terminals

A multi-circuit test shoe adapted to be fitted over a telephone circuit connector block having individual subscriber circuit protector modules thereon, the shoe having means for selectively lifting said modules on an individual basis from fully engaged to detent positions on said blocks.

Test shoe for telephone connector blocks having module retraction means

A subscriber network interface device for multiple subscriber pairs at a common location housed internally in a compact connector block easily mounted upon a wall by screws or a known mounting bracket to eliminate the need for installation of separate one or two line network interface devices. Incoming line connection is made using quick clip elements. Outgoing line connection is made via a female connector which is used to communicate with other quick clips. The circuits are latched in actuated state by the application of a 130 volt direct current applied to the tip or ring side of the line.

Subscriber network interface device

A flexible resilient protective boot for shielding an engaged telephone subscriber plug and jack interconnection against moisture, vermin, insects and the like. The boot is suitable for installation by the subscriber without the use of tools and employing only ordinary skill. In each of the embodiments, the boot comprises a pair of separable members which are spreadable to enclose part of the plug structure, and resilient means engaging said separable members to maintain them in abutted relation.

Protective boot for telephone subscriber jacks

An improved telephone modular wall jack particlarly suitable for subscriber installation within the home or other subscriber premises. The jack includes a fixed mounting element slidably engageable with a housing element containing means for stripping insulation from conductors and interconnecting them without the use of tools or special skills. The interconnection of conductors can be accomplished while the housing is in detached condition from the mounting element, following which the housing is attached to the mounting element for installation upon a wall.

Telephone modular wall jack

An improvement for retaining wire type contacts of a rotary switch in position upon a stator to facilitate assembly during manufacture. In lieu of previously employed glued or heat sealed construction, the improvement is provided with a resiliently expandable periphery which engages an annular shoulder on the stator element without resort to the use of tools or adhesives.

Wire contact retention means for rotary switches

An improved terminal pin and mounting construction therefor, for use in multicontact switches using flexible wire type contacts mounted upon a stator element, the contacts being bridged by corresponding contacts on a coaxially mounted rotor element. The mounting utilizes improved flexibility of the contact portion of each of the pins to lessen the stress placed upon the fixed mounting portion thereof.
