A testing arrangement is provided for testing the electrical circuits of an assembly of terminal blocks arranged in side-to-side relation, each of the terminal blocks including two mutually-insulated collinearly-arranged horizontal bus bar sections that are normally electrically connected by first and second pairs of leaf spring contacts arranged above and below the bus bar sections, respectively. During the testing operation, the testing device may be arranged either above or below the assembly, and an insulating test plug on the testing device is inserted either vertically downwardly from above, or upwardly from below, the terminal block, thereby to disengage one pair of contacts. A dummy plug is vertically inserted in the opposite direction to disengage the other pair of contacts. The remote ends of the bus bar sections are provided with clamping devices for connection with the bare ends of insulated conductors, respectively.

Test and connection apparatus arrangement, and connection apparatus

A testing arrangement for testing the electrical circuits of a terminal block assembly, comprising a generally rectangular testing unit housing formed of insulating material and containing a chamber, at least one connection device mounted in chamber and having an elongated connector body formed of insulating material and including center and end portions. An integral measuring tab portion extends downwardly from the body center portion for insertion into a testing opening contained in the terminal block assembly, and a pair of coplanar measurement portions extend upwardly from the connector body ends and terminating at different elevations, thereby to afford a compact testing arrangement. Two electrical circuit connecting portions are mounted on the connector body, each including an input conductive contact plate mounted on one side of said measuring tab portion, and an output contact mounted within one of said measurement portions for connection with one end of a testing component.

Test and connection apparatus arrangement, and test apparatus

A terminal block arrangement includes a plurality of generally rectangular terminal blocks having vertical parallel side walls, vertical end walls, and horizontal top and bottom walls, a connecting arrangement connecting said terminal blocks in contiguous side-by-side stacked relation, thereby to define a terminal block assembly in which at least portions of the terminal block top and bottom walls are exposed, and a fastening arrangement for fastening the bottom portion of the terminal block assembly to a fixed support. In a first embodiment, the fastening arrangement includes vertically displaceable end support members arranged at each end of the terminal block assembly, each support member having pairs of support feet arranged for connection with the fixed support. In a second embodiment, an adapter plate is secured to the fixed support, and the terminal block assembly is fastened to the adapter plate.

A connector arrangement includes a flat conductor component having a flat engagement portion, a conductive bus bar component having a flat engagement portion, and a conductive contact screw connecting the conductor and bus bar flat engagement portions in contiguous surface-to-surface electrical engagement. The contact screw has a pointed tip and is axially displaceable from a retracted position normal to and spaced from the flat conductor and bus bar engagement portions toward a connected position in which a pointed end of the screw penetrates or extends through openings in the bus bar and flat conductor engagement portions, and into a bore contained in a housing support surface. The housing support surface supports the flat engagement portions in either a horizontal orientation or a slightly inclined orientation relative to the horizontal upper surface of electrical panel component to which the flat conductor is connected and upon which the housing is mounted.

Connector arrangement for flat conductors

An electrical connector arrangement includes a resilient contact adapted for direct engagement with the bare wire of an insulated conductor without the use of any assembly tool, characterized in that the resilient contact includes a first leg having a first end containing a window opening, a second leg having a first end extending at an acute angle through the window opening for clamping engagement with a conductor bare wire that is also inserted in the same direction therein, and a connecting portion connecting the other ends of the first and second legs to define a closed loop. A clamping edge at the extremity of the first end of the second resilient contact leg engages the bare wire and cooperates with a first edge of the window opening to prevent the withdrawal of the bare wire from the window opening. A conductive bus bar may be provided that includes a projecting portion that extends into the window opening between the bare wire and the window first edge, whereby the bare wire is clamped between the clamping edge of the second leg of the resilient contact and the bus bar projecting portion.

Connector apparatus adapted for the direct plug-in connection of conductors

A locking device serves to lock an electronic module to a bank of terminal blocks, characterized by a body member having at least one pair of integral parallel spaced legs that extend downwardly within a corresponding T-shaped vertical groove contained in one end of a first one of the terminal blocks. The legs are resiliently biased apart and are provided at their free ends with hook or catch portions that extend laterally outwardly from opposite sides of the legs into corresponding locking recesses contained in opposite side walls of the groove, respectively, thereby to lock the body member with the bank of terminal blocks. The adjacent end of the body member contains a longitudinal chamber that slidably receives a locking member that is displaceable between retracted unlocked and extended locking positions relative to the body member. Accordingly, when the locking member is in the retracted position and a vertical locking tongue of T-shaped cross-sectional configuration integral with a side wall of the housing of the electronic module is inserted within the T-shaped groove of a second terminal block of the bank, the locking member may be displaced to its extended position above the locking tongue, thereby to fasten the module with the terminal block bank.
