Female Electrical Receptacle

Abstract

The present invention is a housing comprising of a female power receptacle. The housing may have one or more electrical contacts inside. The housing may have a raised flat, circular surface. Said raised surface may have one or more openings on it corresponding to the location of the electrical contacts inside. The raised circular surface may have a rotatable ring around it with wedge shaped features on its interior surface which, when rotated, apply pressure to elongated pins on the interior of the housing, which then apply pressure to the electrical contacts inside. In another embodiment the housing may have an outer sleeve which when moved along the housings longitudinal surface may apply pressure to the interior pins which may then apply pressure to the electrical contacts inside.

Claims

1. A device for making an electrical connection that stays securely in place and simultaneously maintains tight electrical contact between the male and female contacts that is also readily disconnect-able, said device comprising: a female electrical receptacle having internal electrical contacts, may have a rotatable outer ring and internal pins positioned at a right angle to the internal electrical contacts that may apply pressure to the internal electrical contacts there by securing them in place and maintaining a tight electrical contact.

2. A device as defined in claim 1, said device comprising: a female electrical receptacle, said female receptacle having one or more internal electrical contacts, said female receptacle having a raised flat side, said raised flat side having openings corresponding to the electrical contacts inside, further, said raised flat side being circular in shape and having an exterior rotatable ring that may have one or more wedge shaped surfaces on it interior side formed to be a female receptacle.

3. The device as claimed in claim 2 further including one or more internal tubular space's located at a right angle to the internal electrical contacts and extending between the internal electrical contacts and the outer rotatable ring.

4. The device as defined in claim 3 further including elongated pins located inside said tubular space's, that extend the length of the tubular space so that when the rotatable ring is rotated the wedges on the internal side of the rotatable ring come into contact with the elongated pins housed within the internal tubular spaces and compress said pins against the internal electrical contacts.

5. Said device as defined in claim 1 further including directional arrows upon exterior side the rotatable ring.

6. Said device as defined in claim 1 further may include an outer sleeve that interacts with the internal pins.

7. Said device as defined in claim 1 may also use a lever attached to the body with pivot point positioned over the internal pins that apply pressure to the pins when rotated 180 degrees.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] FIG. 1 is one embodiment of the present invention that shows a frontal cut away view of a single female receptacle with an exterior rotatable ring 4 having raised ridges 8 on its exterior surface and wedges 5 on its interior surface, and internal pins 7 inside tubular spaces 6 located at a right angle to the electrical contacts 2; the body 1 further shows a round raised surface 3 having openings 9 exposing electrical contacts 2; the wedges 5 on the interior surface of the outer ring 4 as illustrated will come into contact with the internal pins 7, when rotated as someone skilled in the art would understand, compressing them against the internal electrical contacts 2.

[0021] FIG. 2 is a side cross sectional view of FIG. 1 showing single female receptacle on the body 1 with a rotatable ring 4 with directional arrows 10 on its outer surface and pins 7 at a second right angle to the metal contacts 2;

[0022] FIG. 3 is another embodiment of the present invention that shows an outer sleeve 11 that when manually moved along the longitudinal axis of the round raised part of the body 3 compresses the pins 7 against the electrical contacts 2 inside;

[0023] FIG. 4 is another embodiment of the present invention that shows levers with elongated base 12 positioned over the internal pins and attached with hinge points 13 on the outer surface of the round raised part of the body 3, that when pivoted 180 degrees apply pressure to the internal pins 7.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The present invention provides a unique female electrical receptacle for securely connecting a male electrical connector and maintaining a tight electrical connection.

[0026] Referring to FIG. 1, a device body 1 for securing a male electrical contact in a secure manor and maintaining a tight electrical connection is shown in front view. The device has an electrical contact 2 accessed by the opening 9 in the flat raised circular surface of the body 3. A rotatable ring 4 with wedges 5 on its interior surface, and ridges 8 and directional arrows 10 on its exterior surface, when rotated, interact with the elongated pins 7 which are positioned inside the tubular spaces 6. When the rotatable ring 4 is rotated the wedge 5 on its interior surface compress against the elongated pins 7 that are housed in the tubular space 6 which in turn compress the pins 7 against the internal electrical contact 2. This compression provides resistance against the male electrical contact after it is inserted into the female receptacle and locked while simultaneously providing a secure insertion of the male electrical contact as well as maintaining a tight electrical connection between the male and female electrical contacts. The raised ridges 8 on the exterior of the rotatable ring 4 may allow ease of operation. The body 1 and outer ring 4 of the receptacle may be molded from plastic and formed using metal, for ease of manufacturer, both known conventionally. The elongated pins may be made of a non- conductive material or conductive material and encapsulated in a non-conductive material as would be needed as shown and understood by one skilled in the art.

[0027] The present invention is pictured in a NEMA 5-15R configuration however, there are numerous configurations of male-female temporary electrical connectors available for different applications. All of them being compatible with the present invention design features set forth here however, since many modifications, variations, and changes in detail can be made to the described embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents and not limited by the illustrated embodiments.
