Abstract

Abstract The invention relates to a protective device for the wiring field disposed on a backplane (8) of a subassembly carrier (2). According to the invention, a U-shaped lateral section (16) is provided, at the one leg (18) of which a strip-shaped fastening extension provided with cutouts (22) and to the other leg (26) of which a receptacle (28) provided with a longitudinal channel (30) are attached. The lateral parts (6) of the subassembly carrier (2) are detachably connected in the vicinity of the rear transverse bars (4) to a U-shaped lateral section (16) in such a manner that the U-shaped lateral sections (16) enclose the wiring field of the backplane (8). A wiring shield plate (32) folded longitudinally is connected detachably to the lateral sections (16) by fastening elements (34) via the receptacle (28) in such a manner that the wiring field of the backplane (8) is enclosed. Thereby, a protective device for a wiring field of a backplane (8 ) of a subassembly carrier (2) is obtained, in which the wiring shield plate (32) can be removed from the back side without disassembling the subassembly carrier (2).

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 137 words
In a subassembly carrier which includes a transverse bar, two opposed lateral parts, a backplane and a wiring field of parallel pins disposed on and extending away from the backplane, a protective device comprising: at least one U-shaped lateral section, the U-shaped lateral section having a lateral portion and two legs extending transversely from opposite ends of the lateral section, a first one of the two legs being connected to one of the two opposed lateral parts, a second one of the two legs including a longitudinal receptacle having a longitudinal channel formed therein; a shield plate cooperating the the U-shaped lateral section to enclose and protect the wiring field, the shield plate being releasibly secured to the second one of the two legs; and a fastening means for detachably fastening the shield plate to the receptacle.
Claim 2
Dependent Claim 137 words
In a subassembly carrier which includes a transverse bar, two opposed lateral parts, a backplane and a wiring field of parallel pins disposed on and extending away from the backplane, a protective device comprising: at least one U-shaped lateral section, the U-shaped lateral section having a lateral portion and two legs extending transversely from opposite ends of the lateral section, a first one of the two legs being connected to one of the two opposed lateral parts, a second one of the two legs including a longitudinal receptacle having a longitudinal channel formed therein; a shield plate cooperating the the U-shaped lateral section to enclose and protect the wiring field, the shield plate being releasibly secured to the second one of the two legs; and a fastening means for detachably fastening the shield plate to the receptacle.
Claim 3
Dependent Claim 22 words
The protective device according to claim 1, wherein one said lateral part and said U-shaped lateral section are made in one piece.
Claim 4
Dependent Claim 31 words
The protective device of claim 1 wherein said first leg has a strip-shaped fastening extension with a plurality of cutouts (22) for fastening said lateral section to one said lateral part.
Claim 5
Dependent Claim 32 words
The protective device of claim 1, wherein the longitudinal channel has a plurality of parallel screw receiving grooves formed therein, the parallel grooves extending along the entire length of the longitudinal channel.
Claim 6
Dependent Claim 27 words
The protective device of claim 4, wherein the fastening means comprises at least one screw releasibly received in the screw receiving grooves formed in the longitudinal channel.
Claim 7
Dependent Claim 20 words
The protective device of claim 1, wherein the fastening means comprises screw means releasibly secured to the U-shaped lateral section.
Claim 8
Dependent Claim 24 words
The protective device of claim 1, wherein the shield plate is bent along a predetermined line so as to define two substantially transverse portions.
Claim 9
Dependent Claim 14 words
The protective device of claim 7, wherein the substantially transverse portions are substantially planar.
Claim 10
Dependent Claim 44 words
The protective device of claim 7 wherein both the substantially transverse portions are also substantially transverse with respect to the lateral portion of the U-shaped lateral section such that the transverse portions and lateral portion cooperate to protect the wiring field in three directions.
