Abstract

Cross-bar distribution frame, particularly for use in central electrics of motor vehicles. The object of the present invention is to further develop the known cross-bar distribution frame of the generic type for use in central electrics of motor vehicles in such a way that the central electrics can be produced in a flat design, that optionally, and depending on predetermined current paths to be determined in the individual case, a coding of the current path within the matrix formed by the cross-points of the cross-bar distribution frame can be carried out, and that the current route can also be changed with simple means for adjustment to altered circuit diagrams and terminal diagrams. According to the invention it is proposed that a first connection side of in each case identically aligned busbars (I, II) be provided with flat connectors (9), with clamping screws (10) and also with at least one line terminal (11), that located on a second connection side of the in each case identically aligned busbars (I, II) are, with respective formation of at least one relay connection contact spring configuration (A, B, C, D) and at least one fuse connection contact spring configuration (A, E), contact springs (A, B, C, D, E), as well as at least one line terminal (11), all terminals (9, 10; A, B, C, D, E; A, E) being arranged on side walls (2, 3, 4, 5) of the housing (1), and that the individual plug-on contact element (12) has a square basic body (13) with quadratic base area of the lateral length (z), in each case a pair of mutually opposite first clamping tongues (16) or second clamping tongues (17) being formed on the inner wall side in a recess (15) of the base body (13) on the cross-bar side, each clamping tongue (16, 17) having two resilient first clamping lugs (19) or second clamping lugs (20) which are arranged in pairs beside one another, are identical in form and material, and are separated from one another by a slit (18), and the second clamping lugs (20) being shorter than the first clamping lugs (19) by the grid distance (Z). The connection of electric components, which is to a large extent not liable to interference with respect to contacting and vibration strength, to central interfaces of the motor vehicle electrical system is advantageous, as well as the further modularisation thereof with reduction in the number of cable trees and also the low mounting depth and stackability of the cross-bar distribution frame according to the invention. <IMAGE>
