Abstract

A terminal assembly for a cable having a multiplicity of conductors, particularly having a relatively high number of small gauge conductors, and providing an individual terminal for each conductor. The terminal assembly comprises a terminal block having a plurality of terminal cavities at one face of the block to receive respective terminal elements and a plurality of conductor apertures in the opposite end of the terminal block. The respective conductors with or without a terminal element connected thereto pass through each conductor aperture to be connected to a terminal element in, or to be located in, a respective terminal cavity. Locking means are provided of the terminal block adapted to anchor each conductor to the terminal block to thereby limit the transmission of cable or conductor movement externally of the terminal block to the terminal elements. The locking means includes an element selectively movable between a first position permitting passage of the conductors with or without a terminal element connected thereto through the conductor apertures into the terminal block and a second position locking each of the conductors relative to the terminal block.

Dependent claims

A multi-conductor terminal assembly comprising a terminal block having at least two terminal cavities at one face of the block to receive respective terminal elements;

at least two conductor apertures in a second face of the terminal block arranged to permit respective conductors passing therethrough to be connected to a terminal element in, or to be located in, a respective terminal cavity;
an anchor mechanism operable to anchor each conductor to the terminal block, said anchor mechanism including a locking element selectively movable between a receiver position permitting passage of the conductors through the conductor apertures, and a retention position locking each of said conductors relative to the terminal block, the respective conductors being substantially in alignment with said respective terminal cavities when said locking element is in said retention position, a substantial surface area of said locking element remaining in slidable contact during the locking operation with a substantial portion of said second face in which the conductor apertures are located, said locking element comprising a lock member having at least two lock apertures therein corresponding in number and formation to the conductor apertures in the terminal block, said lock member being in the form of a plate supported relative to the terminal block to move in a direction at right angles to the direction of the conductor apertures wherein the lock member and terminal block are provided with respective elements which automatically engage when the lock member is moved to the retention position thereby preventing undesirable movement of the lock member in the reverse direction and maintaining a grip on the respective conductors.

A multi-conductor terminal assembly comprising a terminal block having at least two terminal cavities at one face of the block to receive respective terminal elements;

at least two conductor apertures in a second face of the terminal block arranged to permit respective conductors passing therethrough to be connected to a terminal element in, or to be located in, a respective terminal cavity;
an anchor mechanism operable to anchor each conductor to the terminal block, said anchor mechanism including a locking element selectively movable between a receiver position permitting passage of the conductors through the conductor apertures, and a retention position locking each of said conductors relative to the terminal block, the respective conductors being substantially in alignment with said respective terminal cavities when said locking elements is in said retention position, a substantial surface area of said locking element remaining in slidable contact during the locking operation with a substantial portion of said second face in which the conductor apertures are located, said locking element comprising a lock member having at least two lock apertures therein corresponding in number and formation to the conductor apertures in the terminal block wherein retention means are provided to retain the locking element in said retention position.

A multi-conductor terminal assembly comprising a terminal block having at least two terminal cavities at one face of the block to receive respective terminal elements;

at least two conductor apertures in a second face of the terminal block arranged to permit respective conductors passing therethrough to be connected to a terminal element in, or to be located in, a respective terminal cavity;
an anchor mechanism operable to anchor each conductor to the terminal block, said anchor mechanism including a locking element selectively movable between a receiver position permitting passage of the conductors through the conductor apertures, and a retention position locking each of said conductors relative to the terminal block, the respective conductors being substantially in alignment with said respective terminal cavities when said locking element is in said second position, said locking element remaining in slidable contact during the locking operation with a substantial portion of said second face in which the conductor apertures are located, said locking element comprising a lock member having at least two lock apertures therein corresponding in a number and formation to the conductor apertures in the terminal block;
and
an end plate mountable to define a cavity between an internal surface of said end plate and said second face of said terminal block in which said locking element is located to move in slidable contact with said second face.
