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.

Terminal block assembly with a plurality of terminal blocks held side by side by a pair of end connecting units

A connector block arrangement includes a first connector block housing having a row of first contacts, a second connector block housing having a row of second contacts in engagement with the first contacts when the connector block housings are in a connected condition, a conductive jumper device having a base portion and a plurality of resilient fingers normally connecting together a group of the second contacts, and an electrically-insulated code device carried by one of the housings for selectively disengaging from the jumper device at least one of the contacts of the second contact group. The code device has a planar generally comb-like configuration including a base portion arranged in an opening contained in either one of the connector block housings, and at least one code bar portion operable to separate a resilient finger of the jumper device from the corresponding contact to be disengaged.

Connector apparatus with code means

A connector junction block of flat thin design is adapted for connection with one or more insulated electrical conductors, and includes base and cover members that cooperate to define a chamber, and an operating member that is mounted in the chamber for movement between first and second positions relative to at least one of the base and cover members. One end of the insulated conductor is inserted into the chamber via a first conductor opening contained in the cover member, and extends into a second conductor opening contained in the operating member. The operating member carries an insulation piercing arrangement that is operable when the operating member is displaced toward its second position to pierce the insulation and electrically engage the conductor. In one embodiment, the cover and base member are connected to define a rigid housing within which the operating member is displaced by an external operating tool. In a second embodiment, the operating member is supported in fixed relation by the base member, and the cover member, together with the conductors supported thereby, are displaced relative to the base member and the operating member, thereby to effect.
