CLAW. wlLsw slvyo JD: 775: 6 By k MM United States Patent 3,530,426 CONNECTOR HOUSING Clair Wilson Snyder, Jr., Hellam, Pa., assignor to AMP Incorporated, Harrisburg, Pa. Filed Apr. 25, 1968, Ser. No. 724,147 Int. Cl. H01r 9/16, 9/22 US. Cl. 339-128 7 Claims ABSTRACT OF THE DISCLOSURE This invention relates to the art of electrical connectors and is concerned primarily with the provision of an inexpensive housing for insertion in an aperture in a panel or the like.

Many housings are known in the prior art for positioning electrical contacts within a panel aperture. It is customary for these housings to be molded pieces having apertures for receiving contacts and having some means for retaining the housing in position within the panel aperture. These molded housings frequently represent a large portion of the cost of the connector unit due primarily to the extremely high cost of molding equipment. In addition, the wide range of uses to which the connectors are put requires a great number of housing sizes to accommodate various numbers of contacts. Each housing size would, of course, require its own mold.

The above-mentioned high costs and number of housing sizes are reduced by applicants invention by providing a housing of uniform cross-section and of an insulating material easily adapted to an extruding process. Applicants housing has a central portion with legs on either side integral therewith and being pivotable so as to allow for insertion into a panel or chassis. Each leg has shoulders thereon forming a groove for mating and locking with a panel. The central portion has abutments thereon for limiting the pivotable movement of the legs and thereby preventing overstressing of the legs. Contacts are adapted to be receptively mounted in apertures provided in the central portion.

It is an object of this invention to provide a connector housing of uniform cross-section thereby permitting the housing to be formed by an extruding process.

A further object is to provide a connector housing of indefinite length which could be selectively severed to any desired length to accommodate a desired number of contacts.

A further object is to provide a connector housing which is of simple design and which is relatively inexpensive to produce.

The attainments of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings in which there is shown and described an illustrative embodiment of the invention; it is to be understood, however, that this embodiment is not intended to be exhaustive nor limiting of the invention but is given for purpose of illustration in order that others skilled in the art may fully understand the invention and the principles thereof and the manner of applying it in practical use so that they may modify it in various forms, each as may be best suited to the conditions of a particular use.

BRIEF DESCRIPTION OF THE DRAWING In the drawings in which like reference numerals refer to like parts:

FIG. 1 is a perspective view of a connector made in accordance with the teachings of the present invention;

FIG. 2 is a erspective view showing the housing employed in the connector of FIG. 1;

FIG. 3 is a cross-sectional view of the connector of FIG. 1 prior to insertion in a panel aperture;

FIG. 4 is a cross-sectional view similar to FIG. 3 showing the connector during insertion in the panel aperture;

FIG. 5 is a cross-sectional view showing the connector of FIG. 1 positioned within the panel aperture;

FIG. 6 is a fragmentary top plan view of the panel aperture configuration for receiving the connector; and

FIG. 7 is a fragmentary top plan view showing the relative positioning of a connector within a panel aperture.

DESCRIPTION OF THE PREFERRED EMBODIMENT The connector of the present invention is indicated generally at 10 and includes a housing 12 and a plurality of electrical contacts 14. The housing 12 is of substantially constant cross-sectional configuration and comprises a central portion 16 and a pair of legs 18 disposed on opposite lateral sides of the central portion. The constant cross-sectional configuration of the housing permits it to be extruded in indefinite length as indicated in FIG. 2. A plurality of apertures 20 are preferably punched in the central portion 16 of the housing for receiving the electrical contacts. The spacing between apertures 20 may be varied as desired depending on the contact spacing employed for each particular use.

Housing 12 is preferably formed of an electrically insulating material such as nylon to prevent shorting between the electrical contacts and the panel within which the connector is inserted. The material must be sufficiently resilient to permit the legs 18 of the housing to have a springing action in a manner to be described.

The legs 18 are joined to the central portion 16 by a hinge section 22. The hinge section is sufficiently narrow to permit the legs to move in a pivotal manner relative to the central portion. A pair of large arcuate cutouts 24 are formed adjacent the hinge sections 22 and serve both to provide clearance between the legs and the central portion and also to yield a longer elfective leg length.

Each leg 18 has a pair of oppositely disposed shoulders 26 and 28 adapted to be positioned on opposite sides of a panel or chassis 30 within which the connector is to be mounted. The lateral dimension between the legs 18 is of appropriate size for insertion Within an aperture 32 in the panel 30.

When it is desired to produce a connector the housing 20 is severed to appropriate length to accomodate the necessary number of contacts 14. The contacts 14 are inserted into the apertures 20 in the housing either before or after severing the housing to length and are held therein by frictional forces and by the abutment 34 (if desired) formed on the contacts. The panel aperture 32 is then formed of an appropriate size to receive the connector and the aperture preferably is provided with radiused end portions 36 for positioning the connector. The length of the connector 12 should be just larger than the straight line portion of aperture 32 whereby the radiused ends 36 will serve to maintain the connector centrally located within the aperture.

The connector is inserted into the panel aperture as seen in FIG. 4 with the rounded external surface of the hinge sections 22 providing appropriate lead in. The

legs 18 of the housing pivot inwardly as the housing passes through the aperture 32. In the event the aperture 32 is slightly smaller than it should be, the legs 18 could be forced to pivot inwardly to a point in excess of their elastic limit whereby the legs would be permanently deformed. To prevent against such occurrence the central portion 16 of the housing is provided with laterally extending abutment means 38 which would contact the legs 18 and prevent the legs from being bent beyond their elastic limit.

When the connector is fully inserted within the panel aperture the shoulders 26 and 28 will lie on opposite faces of the panel 30 and will retain the connector in position. The legs 18 will, of course, return to their normal position as shown in FIG. 5. It is preferable that the connector be inserted into the panel in the direction which is opposite to the direction in which the aperture 32 was punched. Punching of the aperture causes a slight radius 40 to be formed along one surface of the aperture and this small radius could have a detrimental effect on the holding characteristics of the shoulders 26 and 28 if the housing were to be inserted in the same direction as the punching direction.

It can 'be seen that a connector has been provided by this invention which is inexpensive to produce and which is extremely versatile in that a continuous housing length may be selectively severed to produce a connector of any desired size.

Changes in construction will occur to those skilled in the art and'various apparently different modifications and embodiments may be made without departing from the scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only.
