Modular test plug adapter

Combined eight conductor modular plug and test adapter

A tool for inserting a wire between resilient contact portions of a connector is presented. The tool has a handle portion and a reversible stem portion and the stem portion includes a body portion having a pair of blades extending from opposite sides thereof. The blades are generally in the form of I-beams and, in use, the channels at either side of the beam engage the connector contact portions while the web portion of the beam serves as anvil which supports the wire in the region between the contacts during insertion. The blades each comprise a pair of spatially displaced flanged members interconnected by a web member. Each flange member has width substantially equal to the width of the body portion.

Conductor insertion tool

A 'universal' eight wire modular plug capable of insertion into any 6 or 8 wire modular jack is presented. The modular plug comprises eight conductive contacts, each conductive contact respectively attached to a wire leading therefrom, all of which are encased in an insulating housing. The eight wire modular plug housing has a streamlined configuration which permits entry thereof into any 6 or 8 wire modular jack. A pair of ramps are also provided to the modular plug to insure snap-fitting into certain 6 wire jacks having interior obstructions.

Eight conductor modular plug

An 8 wire modular plug ended test adapter capable of insertion into any 6 or 8 wire modular jack is presented. The modular adapter comprises 8 conductive contacts encased in a plastic housing, and respectively attached to 8 wires preferably leading from a modular plug, the contacts being sufficiently wide to accommodate alligator chips or the like. Pair number of contacts are clearly molded onto the housing to facilitate use. The modular adapter provides access to a 6 or 8 wire jack for telephone butt sets, test equipment, etc.

Eight conductor modular test adapter

A connector block including wire-formed multiple solderless connectors having an improved wire wrap pin assembly is presented. The block has retainer and body sections with slots and bridge elements to house and define rows and columns of the connectors. The block is further provided with improved wire wrap pins which project from one side of the block and which are in mechanical and electrical contact with the wire-formed solderless connectors. In a preferred embodiment, the wire wrap pins have a two-pronged fork mounted on a rod-like base portion.

Multiple electrical connector block with improved wire wrap pins

A modular test plug adapter for insertion directly on a telephone terminal block of the type having a plurality of connectors extending therefrom (i.e., 66 type terminals) is presented. The test plug adapter is comprised of a compact insulative housing having a plurality of apertures therethrough, each aperture leading to a cavity having a bridge clip therein. The bridge clips are preferably quick connect type bridge clips and are connected via wire conductors to a standard modular jack for accessing test phones or other test equipment. The present invention may be configured for any size modular jack including 2, 4, 6 or 8 wire jacks.

A modular connecting block comprising a block of insulating material having a plurality of apertures therein, each aperture having inserted therein a plurality of flat elongated conductive elements, the elements including at least one pair of opposing contact fingers which protrude upwardly from and are integral with a base portion of the elements, the contact fingers extending through said apertures to allow for connection of wires to the elements, the elements including a tang which is integral with and extends from the base of the element. The modular connecting block may be prewired and includes a plurality of conductive circuits which connect the tangs to various contact points which are positioned external to the block. In another embodiment of the invention the block comprises a parallelepiped having a projecting edge along the bottom of one longitudinal side thereof. The projecting edge is interrupted at a predetermined distance from one end thereof by a recess and at the same distance from the other end by a securing protrusion. The width of the recess is at least as great as the width of the securing protrusion so that when such two blocks are placed with their projecting edges in face to face contact, the protrusion of one will mate with the recess of the other.

Modular connecting blocks

A mounting block for solderless connectors has a retainer and a body section which defines slots for housing terminal defining conductive elements. Incorporated on the body section is a novel wire retaining mechanism comprising a plurality of boots or hoods. Each boot or hood has a hook shape, the end of which preferably faces inwardly towards the middle of the terminal block.

Multiple electrical connector and mounting block with boots

Pre-wired modular connecting blocks

There is disclosed an electrical connector which comprises three adjacent fingers extending from a base. When an insulated electrical conductor is inserted between a pair of fingers, the insulation is crushed or cut making the desired contact. There is also disclosed a block of insulating material containing such connectors.

Electrical connectors and terminal connecting blocks

An adaptor which permits mating electrical cable connectors to be easily and reliably secured to one another comprises a bracket and a self-locking strap, the bracket being positioned between the connectors and the strap extending from the bracket and passing completely around the mated connectors.

Electrical connector hold-down adaptor

A modular block, base and bracket assembly is presented for effecting electrical interconnections. The bracket is configured to receive one entire block and part of another block so that brackets can be mounted in series whereby three blocks can be mounted on two brackets.
