Abstract
Abstract An enclosure for electrical components is provided having an Lshaped base and integral sidewall and a preferably transparent cover; connecting pins are moulded through the base in a conventional manner and the cover has lips so that it can be slid onto the base in a direction at right angles to the axis of the pins; thus the cover cannot become detached during engagement or extraction of the pins in their socket components, such as relays may be mounted on the integral sidewall; a snap action lock remote from the base indicates closure positively.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
A plug-in type component comprising: an insulating base having a plurality of rigid electrical conductors fixedly mounted therein and extending therethrough; a wall integral with and projecting away from said base; and a separate cover cooperating with the base and the wall and enclosing a volume therewith, the cover having means gripping the base upon the upper and lower surfaces thereof upon assembly with the base by movement relative thereto in a direction substantially at right angles to the direction of force for engagement for disengagement of the rigid electrical conductors from a plurality of connectors in a socket.
Claim 2
Dependent Claim
99 words
A plug-in type component comprising: an insulating base having a plurality of rigid electrical conductors fixedly mounted therein and extending therethrough; a wall integral with and projecting away from said base; and a separate cover cooperating with the base and the wall and enclosing a volume therewith, the cover having means gripping the base upon the upper and lower surfaces thereof upon assembly with the base by movement relative thereto in a direction substantially at right angles to the direction of force for engagement for disengagement of the rigid electrical conductors from a plurality of connectors in a socket.
Claim 3
Dependent Claim
33 words
A plug-in type component as defined in claim 1 wherein the cover means gripping the base comprises a pair of inwardly projecting lugs spaced apart so as to accommodate the base thickness therebetween.
Claim 4
Dependent Claim
18 words
A plug-in type component as defined by claim 2 in which the base has two free parallel sides.
Claim 5
Dependent Claim
32 words
A plug-in type component as claimed in claim 3 in which the base is generally rectangular and the inwardly projecting lugs extend the length of the three free sides of the rectangle.
Claim 6
Dependent Claim
36 words
A plug-in type component as claimed in claim 2 wherein the base is provided with a recessed register to accommodate the lug of the cover so as to present a substantially planar surface to the socket.
Claim 7
Dependent Claim
38 words
A plug-in type component as claimed in claim 1 wherein the wall has two ribs with outward facing registers adjacent the sides of the wall, the cover engaging the rib registers to provide a face to face seal.
Claim 8
Dependent Claim
52 words
A plug-in type component as claimed in claim 6 in which the ribs each have an undercut extension to provide a small projection at the end distant from the base, and the cover has recesses cooperating with said projections to provide a snap-action assembly at the cover with the base and sidewall.
Claim 9
Dependent Claim
31 words
A plug-in type component as claimed in claim 1, in which the base and sidewall are light colored and the cover is transparent to facilitate inspection of the component without removal.
Claim 10
Dependent Claim
137 words
A plug-in type electric relay comprising: a rectangular generally flat insulating base having a plurality of rigid electrical conductors fixedly mounted therein and extending therethrough; a rectangular generally flat wall integral with said base at one side thereof and at right angles to the plane of said base, said wall having two ribs providing two external locating registers and two internal locating registers, adjacent the sides of the wall; a cover cooperating with said base and wall and enclosing a volume therewith, the cover having means gripping the base at the upper and lower surfaces thereof so as to prevEnt relative movement at right angles to the plane of the base while allowing relative movement in the plane thereof for assembly; and a flat magnet yoke supported by said wall and located by said internal locating register.
Claim 11
Dependent Claim
137 words
A plug-in type electric relay comprising: a rectangular generally flat insulating base having a plurality of rigid electrical conductors fixedly mounted therein and extending therethrough; a rectangular generally flat wall integral with said base at one side thereof and at right angles to the plane of said base, said wall having two ribs providing two external locating registers and two internal locating registers, adjacent the sides of the wall; a cover cooperating with said base and wall and enclosing a volume therewith, the cover having means gripping the base at the upper and lower surfaces thereof so as to prevEnt relative movement at right angles to the plane of the base while allowing relative movement in the plane thereof for assembly; and a flat magnet yoke supported by said wall and located by said internal locating register.
Claim 12
Dependent Claim
34 words
A relay as claimed in claim 9 in which the base and sidewall are light colored and the cover is transparent to facilitate on side examination of the contacts and inspection of relay action.
Claim 13
Dependent Claim
44 words
A relay as claimed in claim 9, having a tapped hole in the core laminations through and perpendicular to the plane of the yoke and a clearance hole in the flat sidewall, so as to permit the assembly to be mounted by the sidewall.
Claim 14
Dependent Claim
53 words
A plug-in type electric relay as claimed in claim 9 in which the base adjacent the wall has a recess, the width of the magnet yoke material thickness and a portion of flat magnet yoke continues into the recess so that the recess will grip the yoke portion and tend to prevent distortion.
Claim 15
Dependent Claim
35 words
A plug-in type relay as claimed in claim 12 in which the magnet yoke has a portion at right angles to the flat plane and adjacent the base, said portion being fixed to said base.
