DETACHABLE ELECTRICAL CONNECTOR Filed June 14, 1937 Y. MW m 3 m m A w Patented Aug. 22, 19 39 UNITED STATES I PATENT OFFICE Application June 14,
4' Claims.
The invention relates to detachable electrical connectors of the type commonly used for connecting various extension conductors of an electrical circuit and for connecting and disconnecting various electrical appliances with so-called wall receptacles or convenient outlets.
An object of the invention is to provide a detachable electrical connector of the character described which will provide for a fast and clean make and break of the electrical circuit and insure a positive high quality contact between the electrical contact members and thereby eliminate a source of loss and wear caused by poor, arcing, contact members.
Another object of the invention is to provide a detachable electrical connectorof the character described which while affording a firm, forceful connection of the electrical contact members will be at the same time readily de-.
20 tachable under a relatively slight opening or separating force.
A further object of the invention is to provide a detachable electrical connector of the character above which, notwithstanding the inclusion of 25 the features mentioned, maybe constructed in a compact standard size unit as heretofore in use.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by'the said drawing and description may be adopted within the scope of the invention as set forth in the claims.
Referring to said drawing:
Figure 1 is a cross-sectional View of a detachable electrical connector constructed in accordance with the present invention.
Figure 2 is an end view of one of the connector members.
Figure 3 is an end view of the other connector member.
Figure 4 is a transverse cross-sectional view of the connector member illustrated in Figure 3 and is taken substantially on the plane of line 44 of Figure 1.
Figure 5 is a cross-sectional view of a detachable electrical connector similar to Figure 1, but showing a modified form of the invention.
drawing consists of detachable connector sections 5 or members 6 and l which are provided with en- 1937, Serial No. 148,017
vgageable electric contact members 8 and 8, and H and I2 respectively which are engaged in the attached position of the members 8 and I to complete an electric circuit through the connector. -As here shown, the member I is substantially in the form of'a more or less common type of wall receptacle and comprises a body or casing made up of half sections I3 and H and which is secured to a mounting plate or strap l6 for securement in a standard type receptacle box" not shown. The contact members H and I2 are here shown reciprocally mounted in bearing portions [1 and I8 provided in the body portion of the member! and are positioned with the engageable sides 18 and 2| thereof at the base of openings 22' and 23 leading to the outer face 24 of the member for the receipt and guidance of the contact members 8 and 8 of the connector member 6. -On attachment of the members the contacts 8 and 8 are extended through openings 22 and 23 and into engagement with the faces 19 and 2| ofthe contacts H and I2. and on movement of the members to a fully attached position the contacts 8 and 8 displace the contacts II and 12. Small helical springs 26 are secured to the contacts II and I2 to resiliently resist their displacement and to insure a firm positive contact of the contact members 8 and 8 with the'contact members. I l and I2.
As a principal feature of the present connector I provide a magnetic means for holding the connector members 6 and l in attached position and for moving such members rapidly into an attached position and similarly causing a quick release of the members. In the form of the invention illustrated in Figures 1 to 4, a horse shoe magnet 21 is mounted in the connector member 1 and is positioned with the free magnetic ends- 28 and 29 thereof exposed at the front face It of the member I and at opposite sides of the contact openings 22 and 23. The magnet may be mounted as here shown in opposed recesses formed in the half sections l3 and H of the member I. Forcooperation with the free ends 28 and 28 of the magnet 21, the other connector member 6 is provided with a magnetic keeper 33 which as here shown is in the form of an annular ring embedded in the forward face 34 of the member 8 opposite to the face ii of the member 1, the ring 33 being so positioned around the contacts 8 and 8 as to engage squarely across the ends 28 and 28 of the magnet. In this manner, upon advancement of the member 8 towards an attached position, the bringing of the keeper into the field of the magnet 2'| will cause a snapping of he member 8 into place and as a result a f st clean make of the electric circuit at the contacts 8, 9, II and I2 is effected. Also on engagement of the keeper 33 with the magnet the sections are firmly held in place and can be only forcibly separated. On detaching the sections, the magnet will hold the keeper up to a certain applied-force and will then abruptly release so as to cause a rapid separation of the member 8 from the member 1 and a clean rapid disconnection of the electrical contact members as a result thereof. It will further be noted that the force of the springs 28 is opposed to the force of the magnet and keeper and in accordance with the present invention, the spring tension is such as to provide a relatively. high contact pressure to insure a good quality contact between the contact members 8 and 9, and I9 and 2|, and the magnetic strength is selected so as to slightly overcome the spring force. In this way the majority of the magnetic strength may be offset by the spring tension and only a slight opening force need be manually applied to break themagnetic grip. Thus while the elec: trical contact members are engaged with a relatively great pressure in the attached position of the coupling, they may be separated by the application of a relatively slight opening pressure to the coupling members.
In the form of the invention illustrated in Figure 5 the magnet 21 is incorporated in the plug member 6' and the keeper 33' is mounted on the wall receptacle I. Preferably, in both of the embodiments one or the other or both of the magnet ends and keeper extend slightly from the opposed abutting sides of the sections 8 and I so as to insure a positive engagement of the magnet and keeper.
While in the present embodiment of the invention a horse shoe type magnet has been used and such type is preferred, substantially any other type of magnet, either of a permanent type or electrically actuated, may be used and of the permanent magnet type I may use a straight magnet bar or a flat crescent type with anappropriate form of keeper of magnetic material on the opposite coupling sections. It will be further understood that while the presentinvention has been particularly illustrated in connection with a detachable plug and wall socket type of electrical connectors, the invention may be applied to substantially all types of detachable electrical connectors.
