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. |

1. An electrical module assembly, comprising:
(a) a fixed support (7; 8); (b) a plurality of electrical modules (4) mounted in side-by-side relation on said support, each of said modules including:
(1) a rectangular module housing (41) having horizontal bottom and top walls, a pair of vertical opposed side walls, and vertical front and rear end walls, said walls cooperating to define that cooperate to define an internal chamber (42), one of said end walls containing a generally-rectangular access opening (411); and(2) at least one vertical planar printed circuit board (9) mounted in said chamber in spaced parallel relation between said side walls, said printed circuit board having a planar horizontal contact (43) extending orthogonally from one side thereof adjacent said access opening; (c) horizontal linear bus bar means (5) arranged externally of said module housing, said bus bar means extending normal to the longitudinal axis of said module housing; and (d) plug-in connector means (3) electrically connecting said bus bar means with said printed circuit board, including:
(1) a generally-rectangular spring housing (31) mounted in said access opening, said spring housing having horizontal top and bottom walls and vertical parallel spaced opposed side walls, said spring housing walls cooperating to define a longitudinal through passage, said spring housing having a first end extending into said chamber via said module housing access opening, and a second end arranged outside said module housing; and(2) an electrically-conductive resilient leaf spring (1) mounted in said spring housing through passage, said leaf spring having intermediate its ends:
(a) at least two vertically-arranged oppositely-directed upper and lower tulip-shaped bent portions (11, 12) connected by a horizontal central leg portion (13),(b) a horizontal top leg portion (111) connected at one end with said upper bent portion, and(c) a horizontal bottom leg portion (121) connected at one end with said lower bent portion, said upper and lower leg portions extending in spaced vertical relation above and below said central leg portion, whereby said upper and central leg portions cooperate to define an upper receiving space (11; 1001), and said central and lower leg portions cooperate to define a lower receiving space (12; 1002), such that said leaf spring has a generally S-shaped configuration;(3) said leaf spring housing side walls at said first end containing opposed horizontal first slots (313) for receiving said printed circuit board contact during the insertion thereof into one of said receiving space when said plug-in unit is inserted into said module housing access opening;(4) said leaf spring housing side walls at said second end containing at least one second slot for receiving said bus bar means during the insertion thereof into the other of said receiving spaces. |
