A lighting arrangement for illuminating a passage, such as a wind tower or tunnel, includes at least one lighting unit having a generally rectangular base with bottom, side and end walls cooperating to define an open-topped chamber, a pair of light energy sources arranged partially in the housing chamber for directing light beams toward opposite ends of the housing, respectively, and a cover member formed of light-transmitting material, which cover member is connected with the base to extend over the light energy sources and to close the housing chamber. The cover member includes a concave dome portion containing a cavity within which the light sources are mounted. Opposite areas of the cover dome portion define collimating devices for concentrating the light beams in opposite directions longitudinally of the passage that is to be illuminated. A plurality of lighting units are longitudinally-arranged in the passage, and are electrically connected in series.

A connector assembly for transmitting electrical energy through a wall opening, including a horizontal generally-rectangular first connector housing arranged on one side of the wall with a collar portion of the first housing extending through the wall opening. The collar portion contains a plurality of horizontal parallel coplanar first through bores in which are mounted a plurality of electrically conductive spring contacts, respectively. A second connector housing arranged on the other side of the wall opening contains a recess receiving the collar portion, and a plurality of second bores extending collinearly opposite the first bores, respectively. An electrically conductive comb member includes a plurality of integral pin portions that extend from a common spine portion through the second bores and into the first bores for electrical engagement with the spring contacts, respectively, thereby to connect conductors arranged on opposite sides of the wall.

An electrical module arrangement for supplying electrical power to a printed circuit board mounted within the housing of an electrical module, including a plug-in electrical connector mounted in an opening contained in an end wall of the module housing. The connector is of the conductive leaf spring S-shaped type, including two reversely-bent portions defining oppositely directed recesses for receiving a bus bar voltage source and a planar contact of the printed circuit board, respectively. In a modification, the leaf spring is W-shaped including three bends, thereby permitting connection of the PCB contact with two separate parallel spaced bus bar arrangements. A plurality of the modules are supported in side-by-side relation either by mounting the module housings on a common mounting rail, or by connecting the plug-in connectors to a common bus bar mounted on a fixed support.

Printing apparatus is provided for printing information on a vertical stack of horizontal vertically-spaced planar objects arranged in a housing, including a separating arrangement for removing the lowermost object from the stack, and a printing device for printing information on the removed object. The stack is supported by a plurality of support arrangements each including a support member mounted for reciprocatory horizontal displacement by an electromagnetic drive device between positions that are adjacent and remote from the stack, respectively. Each support member is guided during this displacement by a guide arrangement including at least one guide lever having a first end pivotally connected with the housing, and a second end connected with a guide follower roller that is in engagement with a guide cam surface carried by the support member. The generation of noise is avoided as a consequence of the accurate guidance of the components.

A marking arrangement serves to identify the various conductors connected with the contacts of an electrical connector, including a plurality of indicia-bearing marking members that are respectively connected with the actuating elements that selectively unlock the resilient retaining devices that fasten the conductors to the connector body. The marking members include shaft portions that extend longitudinally into openings contained in one end of the longitudinally-displaceable actuating members, respectively. The other ends of the actuating members are in engagement with the retaining springs that normally bias the conductors into electrical engagement with conductor seats on contacts contained within the connector through ducts, respectively.

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.
摘要:
A connector arrangement for connecting the bare ends of a plurality of insulated conductors to a horizontal row of first contacts arranged on an electrical device, respectively, including a main housing having a side portion containing a chamber in which the electrical device is mounted, a connector housing pivotally connected with the main housing for pivotal movement about a vertical pivot axis between engaged and disengaged positions, the connector housing supporting a horizontal row of conductor contacts arranged to engage the first contacts when the contact housing is in the engaged position, and a manually-operable locking arrangement for locking the connector housing in the engaged position. The locking arrangement includes a locking projection fixed to the main housing, a catch member movably connected with the connector housing, and an actuating member for displacing the catch member between locked and unlocked positions relative to the locking projection.
