1953 c. A. WOODWARD HOUSING FOR ELECTRIC SWITCHES AND THE LIKE Filed May 26, 1949 \NVENTOR: CLEMENT A.WOODWARD, BY ATTORNEY.
Patented Feb. 3, 1953 HOUSING FDR ELECTRIC SWITCHES AND THE LIKE Clement A. Woodward, Wellesley, Mass., assignor to United-Carr Fastener Corporation, Cambridge, Mass., a corporation of Massachusetts Application May 26, 1949, Serial No. 95,450
Claims. 1
This invention relates to housing assemblies for electric switches and the like which are adapted to snap into engagement with a supporting wall through an opening therein.
The object of the invention is to provide a switch housing assembly comprising a body member and a cap member in which the cap member has means thereon for snapping engagement with the body member, and also means for engagement with a supportin wall when the assembly is inserted into an openin therein.
A further object of the invention is to provide a switch housing assembly comprising a cap memher and a body member in which the body memher is provided with an outwardly extending flange having inclined camming surfaces thereon to cooperate with engaging legs disposed on the cap member to allow assembly of the members.
A still further object of the invention is to provide a cap member for assembly with a housing body having an outwardly extending flang disposed thereabout, in which the cap is provided with attaching legs, some of which are adapted to engage the outwardly extending portion of the body member, and others are adapted to engage a supporting wall when the housing assembly is inserted into an opening therein.
Other objects of the invention will, in part, be obvious, and will, in part, appear hereinafter.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description, taken in conjunction with the accompanyin drawing, in which: 1
Fig. 1 is a perspective view of the component parts of the housing prior to assembly;
Fig. 2 is a view in elevation, partly in section, of the housing assembly in which the cap member is partially assembled onto the body member;
Fig. 3 is a view in elevation, partly in section, in which the cap has been completely assembled on the body member, and the assembly has been mounted in an opening in a supporting panel;
Fig. 4 is an end view of the. housing assembly of Fig. 3.
Referring to the drawing, ther is illustrated a housing assembly It, which is adapted to be snapped into engagement with a supporting wall l2 through an opening l4 therein. The assembly I0 comprises a body l6, which is preferably formed of insulating material such as synthetic organic plastic, and a sheet metal attaching cap l8 which is shaped and arranged to snap into engagement with one end of the body 16.
In the preferred embodiment, the body It is substantially cylindrical, and has an internal bavity 20 for receiving a switch or other device (not shown) to be contained within the housing.
Cir
An opening 22 may be provided in one end of the body for receiving electrical lead wires to be connected to the switch. To provide means for enabling the cap to engage the body, an outwardly extending flange portion 2- 3 is provided, which extends about the periphery of the body adjacent the end to which the cap is to be attached. The flange portion 24 is provided with a pair of inclined camming portions 26 on the sid of the flange nearest the end of the body, which are preferably disposed directly opposite one another. A stop member 28 is provided behind the flange portion approximately midway between the inclined portions for a purpose which will be hereinafter described.
The cap l8 comprises a base 33, which may have open ng 32 for receiving a switch operating plunger, and a series of attaching legs 34 which are arranged about the base to receive the end of the body i6 and the flange portion 24 centrally thereof. A pair of opposite legs 35 and 38 are each provided with a camming surface 40 and an inwardly extending shoulder portion 42. It has been found most convenient to accomplish this by curling the end of the leg under and back on itself, so that the end of the leg serves as the inwardly extendin shoulder portion 42, and the resulting rounded portion serves as the camming surface 40. The other legs are each provided with outwardly extending shoulder portions 44, which are spaced on the legs a predetermined distance away from the base to receive a section of the supporting wall therebetween for engagement by the shoulders 44.
' To assemble the cap and the body, the cap is aligned with the body so that the curled legs 36 and 38 are opposite the inclined portions 26 on the body, with the end of the body centrally disposed within the series of legs 34. The relative dimensions of the parts are such that the legs 34 are able to pass over the end of the body and the flange 24. However the curled legs and 38 engage the inclined portions on the flange, and when the parts are forced together, the camming surface 40 0f the legs rides over the inclined portion 26 on the flange and snap into engagement therebehind. After such engagement, the cap may be easily removed as long as the curled legs are aligned with the inclined portions 26 on the flange. As illustrated in Fig. 3, the cap is then looked into engagement with the base by rotating the cap on the base until a curled leg comes against the stop 28, which is shaped and arranged to pass under the legs 34 during such rotation, but is sufficiently high to engage the curled leg 36 and thereby limit the rotation to a predetermined amount.
After such assembly, the housing may be inserted into the opening 14 in the supporting wall, whereby the outwardly extending shoulders 44 pletely over the end of the body for engagement with the flange.
Since certain other obvious changes may be made in the device without departing from the scope of the invention, it is intended that all mat er contained herein be interpreted in an illustrative, and not in a limiting sense.
