(di. 339-253) ABSTRACT (1F THE DSCLGSURE An elastically deformable socket for receiving an electrical connector plug, a portion of the socket being laterally deformable between a normally open position in which it offers little resistance to the movement of the plug and a closed position in which it tightly grips the plug, the socket including a control member disposed in the path of movement of the plug and operatively associated with the deformable plug portion for causing this portion to move abruptly into its closed position when the plug comes to bear against the control member, the deformable plug portion abruptly returning to its open position when the plug moves out of contact with the control member.
This is a division of applicants copending application Ser. No. 371,905, filed on June 2, 1964, now Patent No. 3,330,752.
Background of the invention The present invention relates to electrical connectors, and more particularly to electrical plug sockets of the elastically deformable type.
It is a primary object of the present invention to assure, in an electrical circuit, a positive contact between a plug and a socket.
It is another object of the present invention to achieve such a Contact through the action of the pressure applied to insert the plug into the socket.
It is still another object of the present invention to provide mechanically simple receptacles which apply a positive lateral force to their mating plugs, the application of such force being triggered by the insertion of the plug.
Yet another object of the present invention is to provide a more forceful contact than that which is obtainable in the prior art spring contact devices.
Summary of the invention Briefly stated, the present invention involves socket members made of elastically deformable material and arranged to pass abruptly from an open state to a closed state, under the influence of a force exerted Iby a plug on a control member when the plug encounters the control member during insertion.
This arrangement permits the simple act of inserting a plug to automatically produce a tight gripping action by the socket, thus assuring a connection which is eX- tremely solid, both electrically and mechanically. Such an arrangement also permits plugs having various sizes and shapes to be firmly held in a given socket.
These and other objects of the present invention are achieved by the provision of an electrical connector socket having a plug contacting portion, deforrning means operatively associated with the contacting portion, and control means operatively associated with the deforming means. The plug contacting portion is arranged for receiving a plug inserted in a longitudinal direction y 3,368,186 Patented Feb. 6, 1968 therein, the portion being transversely deformable between a normally open position, in which it offers substantially no resistance to plug insertion, and a closed position, in which it tightly grips an inserted plug.. The deforming means are arranged for deforming the plug contacting portion abruptly between its two positions. Finally, the control means is biased into a non-deflected position in which it is disposed in the path along which such plug moves during insertion in the socket, and is deflected out of such position when encountered by the plug being in serted, for causing the deforming means to normally maintain the plug contacting portion in its open position when the control means is in its non-deliected position and to abruptly deform the plug contacting portion into its closed position when the plug detiects the control means out of its non-deiiected position during insertion.
In one specific embodiment of the present invention, the plug contacting portion is composed of at least one elastically deformable blade, or leaf spring, While the deforming means are constituted by a bistable elastic means which maintains the blade in its open position when no plug is present in the socket and which is acted on by the control means, when the control means are deflected by an inserted plug, to urge the blade` into its closed position.

Description of the preferred embodiment In the embodiment shown in FIGURES l and 2, the
plug contacting portion of an abrupt closing female connector is composed of two clamping portions 101, 102, integral with a base portion 103; the portions 101, 102, terminating in respective inwardly arched plug engaging portions 105, 104. By means of suitable cutting and deforrning operations, each of the portions 101 and 102 has formed, integrally therewith, deforrning means constituted by a lateral inwardly arched spring member 106 effectively pivoted, at 107, yto the body of its respective portion and, at 108, to a control means constituted by an elastic restoring and control member 109. The member 109 has a finger member 110 cut in its center and folded so as to extend into the region enclosed by the female connector and into the path along which a plug will move during insertion.
The spring member 106 is permanently deformed in such a Way Ithat it can assume either one of two stable states, in one of which it flexes inwardly of the region defined by the connector, as shown in FGURE 1, and in broken lines in FlGURE 2, and in the other 0f which it is flexed outwardly thereof, as shown in solid lines in FIGURE 2. The flipping from one stable state to the other is caused by the lateral deflection of control member v109, this deflection Abeing urged by a pressure applied against finger 110. When no pressure is being applied on this Ifinge-r, the elastic forces existing between member 110 and its respective clamping portions tend to urge the spring 106 towards its inwardly deected state. It thus results that, in the normally open state of the connector the 3 springs 106 have their concave faces toward the exterior, causing the plug engaging members 104 and 105 to be in an open state.
When a plug is inserted into the female connector thus formed, it moves thereinto until its leading edge encounters the fingers 110, at which time it exerts an outward pressure `thereon which causes the members 109 to bend outwardly. This movement induces an abrupt iiexure of springs 106 from their inwardly curved state to an outwardly curved condition, the new spring positions abruptly moving plug engaging portions 104 and 105 firmly against the side walls of the inserted'plug. Upon plug withdrawal, the plug need only move against the strong gripping pressure of members 104 and 105 for a short distance until clearing fingers 110 because once these fingers no longer bear against the plug, the elastic forces on member 109 and the pressure of the plug against portions 104 and 105 combine to cause the spring 106 to return to its original stable state, thus inducing an abrupt opening of the plug engaging contacts 164 and 105.
In the embodiment shown in FIGURE 3, a bistable spring element 111 constitutes the rear portion of a strip produced by a series of cuts 112 taken in the body of the female connector contacting portion. The front portion 113 of this strip is folded towards the interior of the region enclosed by the connector unit to form a control means having an abutting surface for a plug to be inserted. The element 111 `thus has one end integrally and elastically joined to the -body of the connector along linear region 114. The front edge of this element comprises a salient finger 115 extending across from a similar finger 116 formed in the front edge of the opening created in the wall of the connector by cuts 112. An arched spring member 113, having appropriate slots therein, is held in place in the opening in the connector wall by the fingers 115 and 116, inserted into respective ones of these slots. The spring 118 constitutes, together with fingers 115 and 116, the deforming means of this embodiment and serves to return the contacting portion to, and maintain it in, its `open position. This closing of the connector is here produced by the outward deflection of spring elements 111 under the pressure of plug (not shown) against abutting surfaces 113, which deflection is translated into a closing of the forward portions of the female connector arms through the intermediary of rotation induced in the spring member 118.
The embodiment shown in FIGURE 4 is similar to that shown in FIGURE 1 in that the same cutting and forming steps can be followed to produce the elastic restoring element 123 and the bistable arched spring 122 in each of arms 120 and 121 as were employed to produce the corresponding elements 109 and 106 of FIGURE 1. The manner of operation and the way in which a plug gripping action is achieved in the FIGURE 4 device are exactly the same as those described in connection with the embodiment of FIGURES 1 and 2. On the other hand, the cont-rol means is constituted in FIGURE 4 by a spring clip 124 permanently bent into the form of a U having two upright elements 125, of which the forward ends are each arranged on the outside of the connector and are attached to a respective spring element 122 by appropriate means. The rear portions of upright elements 125 are integrally associated with a base portion 127 of spring 124 which passes through the openings 128 in the lower ends of the connector arms 120 and 121 and traverses the bottom of the female connector unit.
When a male plug (not shown) is inserted, it traverses the female connector arms 120 `and 121 until its leading edge abuts on base 127. Continued insertion of the plug causes a rearward movement of base 127, which is translated into a spreading of uprights 125 which induces a sudden outward deflection of spring elements 122, resulting in the abrupt closing of the forward ends of connector arms 120 and 121.
FIGURE 5 shows a preferred manner of producing the deiiecting springs described above, in which a series of lateral slots are cut in order to achieve the desired flexibility.
It will be understood that the above description of the present invention is susceptible to various modifications, changes and adaptations and the same are intended to be comprehended within the meaning and range of equivalents of the appended claims.
