Abstract

Method and apparatus for packaging electronic equipment comprise a housing and a "midplane" that is removably secured to suitable flanges centrally located within the housing. Individual sub-modules (CPU, disk drive, I/O unit, power supply, etc.) have suitable electrical connectors which mate with corresponding connectors on the midplane. The sub-modules are inserted into the midplane from different sides of the housing. The exposed, outer surfaces of the sub-modules may either be finished in final form, or suitable bezels may be placed over the sides of the housing so that the sub-modules can be appropriately accessed for necessary replacement or repair.

Claims

1. A method of assembling an electronic module, said method comprising the following steps:

(a) providing a box-like housing member having two substantially open opposing sides;

(b) providing at least two electronic sub-modules, each of said electronic sub-modules performing a sub-function of said electronic mdoule and each comprising a first connector means;

(c) securing a circuit board within said housing member substantially coplanar with said sides, said circuit board comprising

(i) a plurality of electrical conductors,

(ii) second connector means coupled to said plurality of conductors and located on a first side of said circuit board, and

(iii) third connector means coupled to said plurality of conductors and located on a second side of said circuit board;

(d) inserting a first one of said electronic submodules through one side of said housing member until its first connector means couples to said second connector means; and

(e) inserting a second one of said electronic submodules through another side of said housing member until its first connector means couples to said third connector means;

whereby said electronic module can be assembled without utilizing wiring harnesses.

2. The method of assembling an electronic module recited in claim 1, wherein said circuit board comprises a plurality of electronic components coupled to said electrical conductors.

3. An electronic module, said module comprising:

(a) a box-like housing member having two substantially open opposing sides;

(b) at least two electronic sub-modules, each of said electronic sub-modules performing a subfunction of said electronic module and each comprising a first connector means;

(c) a circuit board within said housing member, said circuit board being secured within said housing member substantially coplanar with said sides, said circuit board comprising

(i) a plurality of electrical conductors,

(ii) second connector means coupled to said plurality of conductors and located on a first side of said circuit board, and

(iii) third connector means coupled to said plurality of conductors and located on a second side of said circuit board;

whereby a first one of said electronic sub-modules may be inserted through one side of said housing member until its first connector means couples to said second connector means, and a second one of said electronic sub-modules may be inserted through another side of said housing member until its first connector means couples to said third connector means, and said electronic module is thereby assembled without utilizing wiring harnesses.

4. The electronic module recited in claim 3, wherein said circuit board comprises a plurality of electronic components coupled to said electrical conductors.
