Abstract

A housing for chip card reader constructed such that is can be assembled without the assistance of tools. The housing is composed of a base, a cover that can be slipped onto said base, and a cap that joins said base to said cover. These parts of the housing are merely plugged together and are secured to one another in the assembled condition of the parts without external fasteners.

Claims

1. A housing for a chip card reader comprising:

a base;

a cover for said base;

a cap for holding said base and said cover together engaged with said cap; and

means integrally formed on each of said base, cover and cap and for retaining said base, cover and cap in interconnected relation, said means being the sole means for interconnecting said base, cover and cap, said means for interconnecting including a plurality of respective recesses in said cover and in said base disposed in registry to form in combination a wall having a plurality of openings when said cover and base are engaged, a plurality of hooks on said cap received in said openings and simultaneously engaging said cover and said base, a deformable noise carried on at least one of said hooks, a receptacle disposed at said wall adjacent one of said openings to receive said noise, and a projection on said receptacle disposed to abut said noise in said receptacle to prevent said noise from exiting said receptacle.

2. A housing as claimed in claim 1, wherein said means for interconnecting further includes:

respective complementary surfaces on said cover and said base permitting said cover to slide on said base to a position substantially closing said base;

a base having a plurality of receptacles therein; and

a plurality of hooks integrally formed on said cover disposed to be respectively received in said receptacles when said cover is in said position substantially closing said base.

3. A housing for a chip card reader comprising:

a cover having a first pair of stepped sliding surfaces,

a plurality of projections, and a wall having a plurality of recesses therein;

a base having a second pair of stepped sliding surfaces complementary to said first pair of sliding surfaces, a plurality of receptacles, and a wall having a plurality of recesses therein, said cover and said base being engageable along said first and second pairs of sliding surfaces to slide said cover over said base to a final position, said receptacles of said base in said final receiving said projections of said cover in said final position, and said walls of said cover and said base being in registry in said final position; and

a cap having a plurality of hooks thereon, said hooks being received in said recesses of said base and said cover in said final position with said cap abutting said walls of said base and cover.

4. A housing as claimed in claim 3 further comprising:

a deformable nose carried on at least one of said hooks;

a receptacle on said wall of said base adjacent one of said recesses disposed to receive said nose when said one of said hooks is received in said one of said receptacles; and

a projection on said receptacle abutting said nose received in said receptacle to prevent said nose from exioting said receptacle.

5. A housing for a chip card reader comprising:

a cover having an end wall;

a base having an end wall;

means integrally formed on said cover and said base for slidably engaging said base and said cover in a sliding direction perpendicular to said end walls to bring said end walls into registry in a final position of said cover, said means for slidably engaging including means for preventing movement of said cover in a direction perpendicular to said end walls and said sliding direction;

means integrally formed on said cover and said base engaging said cover with said base for preventing movement of said cover in said final position in a direction parallel to said end walls;

a cap abutting both said end walls when said cover is in said final position; and

means integrally formed on said cap, said cover and said base for holding said cap against said end walls and for preventing movement of said cover in a direction opposite to said sliding direction when said cover is in said final position.

6. A housing as claimed in claim 5, wherein said means for holding said cap against said end walls is a means for slidably engaging said cap with said end walls in a further sliding direction perpendicular to said sliding direction to bring said cap to a final position, and wherein said housing further comprises:

means for preventing movement of said cap in said final position in a direction opposite to said further sliding direction.
