Description
Field of the Invention
This invention relates to a variable entry connector and more particularly to a variable entry connector having a connector portion and a cord portion.
Background
Many machines are connected to an electric source via a detachable power supply cord-connector. Detachable power supply cord-connectors typically have a female connector portion at one end. The female connector portion couples with a machine such as a computer or monitor.
Detachable power supply cord-connectors offer many benefits over permanently affixed supply cords. For instance, detachable supply cord-connectors offer easy replacement. The machine does not have to be disassembled to replace a worn cord, the cord is simply detached and replaced.
A problem with supply cord-connectors, however, is the manner in which the cord portion of the supply cord is coupled to the connector portion of the supply cord. A power supply cord, for instance, having its cord portion entering the rear of its connector portion, requires the user to position the machine to utilize a rear entry supply cord. The position, however, may not be the optimal location for the machine.
To allow optimal placement of machines, manufacturers provide three types of supply cords: a supply cord with a rear entry cord portion; a supply cord with a left entry cord portion; and a supply cord with a right entry cord portion. It is, however, costly for manufacturers, distributors and users to maintain three types of cords. In addition, the user may have to replace the cord each time it relocates the machine.
My unique and novel invention provides a supply cord-connector that allows a user to vary the position of the cord portion to create a rear entry cord, a right entry cord or a left entry cord. My invention thus allows manufacturers, suppliers and users to stock only a single cord. In addition, users do not need to replace cords every time they relocate the machine.
A previous device connected a plug to a cord portion to allow a user to adjust the cord portion relative to the plug. The cord portion of this plug is rectangular. The rear of the plug has a channel positioned transversely with respect to the plug portion's contacts. The channel has lips. A user can by twisting the cord, manipulate the cord portion into the channel. The cord thus enters the plug from the side.
This type of plug design focuses on allowing a user to manipulate the position of the cord at the point of connection to a power outlet. The intent being to hide unsightly cords. The design is not directed towards allowing a user to vary the cord portion relative to a connector portion at the point of coupling to a machine. Thus, this type of plug does not provide a means which allows for optimal placement of the machine and would not be relied on by one skilled in the art of applicant's invention. In addition, the mechanics of how a user adjusts this plug has drawbacks.
One problem with the plug is that the gap between the plug's lips must be kept relatively wide, otherwise, the cord cannot be manipulated into the channel. Maintaining wide gaps, however, cuts down on the ability of the plug portion to sufficiently retain the cord portion. The mechanisms of my variable entry connector are superior.
My connector portion, at its rear surface, has a slot located at the base of a groove. The groove has a depth which decreases and outer edges which narrow as the groove extends towards the sides of the connector portion. In addition, parts of the rear surface of my connector portion are slanted towards the face of the connector. The user passes the cord portion through the uniquely contoured groove and slot and into a transverse channel causing the cord to extend from the side.
Having the slot at the base of a groove, and having the uniquely contoured groove, facilitate the positioning of the cord in the transverse channel. My unique connector portion allows for a very narrow slot and enhanced retention of the cord portion in the transverse channel.
The shape of my cord portion further facilitates the positioning of the cord in the transverse cord channel. My cord portion has a circumferential cross section. The circular cord portion moves through the slot easier than a rectangular cord.
Another known device discloses an electrical connector that employs a pair of identical body portions which are mated together to grasp an electrical conductor and to provide strain relief to the exiting electrical conductor. Each body portion contains an integrally molded axial half channel and an integrally molded transverse half channel. The body portions when mated form generally cylindrical channels for the passage of a cable sheath. Redirecting the cable requires disassembly and reassembly of the body parts. The device does not encompass a power supply cord but rather is narrowly directed towards a cord which transmits electrical signals. My invention is superior.
It allows the user to vary the position of the cord portion without disassembly and reassembly. My invention allows for the use of a connector portion comprising a single molded piece rather than cumbersome multiple parts.
Another known device is directed towards a fiber optic connector comprising a housing and an optical fiber cable. The optical fiber cable is connected to the housing via a fixture. The fixture interlocking with the housing angularly points the cable relative to the housing. The fixture may be attached to the housing in any of four positions. Each position points the cable relative to the housing in a different angular direction. Again, my invention is superior to this connector.
My invention does not require connection and reconnection of the cable portion to the connector portion to cause a redirection. My supply cord connector does not require the numerous subparts, i.e., a fixture and a housing. My invention does not require disassembly and reassembly to change direction.

The bottom electronic coupling surface has a central region (41) which is perpendicular to the first and second side surfaces. The bottom electronic coupling surface has two rounded portions (43). One of the two rounded portions is integral with the first side surface and the other of the two with the second side surface. Both are integral with the bottom central region.
The connector portion in part defines a hollow axial cord channel (45) which has an exterior opening. The exterior opening opens through the central area of the rear surface of the connector portion. The axial cord channel extends axially in a direction towards the face surface and is substantially parallel to the top and bottom surface and the first and second side surfaces. The axial cord channel is sized to snugly fit the cord portion. The cord portion, when in its first entry position (47), extends into the axial cord channel through the exterior opening and terminates into the contacts as seen in FIG. 3.
The connector portion also defines a hollow transverse cord channel (49). The transverse cord channel is sized to snugly fit around the cord portion when the cord portion is in its second entry position (51) and third entry position (53). The transverse channel includes a first exterior opening (55) and an opposite second exterior opening; the first and second openings being opposite each other. The first exterior opening (55) opens through the rear portion of the first side surface and the opposite second exterior opening (56) opens through the rear portion of the second side surface. The cord, when in its second entry position, extends into the transverse cord channel via the first exterior opening on the first side. The cord, when in its third entry position extends into the transverse cord channel via the opposite second exterior opening on the second side.
The transverse cord channel is substantially perpendicular to the axial cord channel and intersects the axial cord channel. The transverse channel is parallel to the face and has a transverse length which extends across the width of the connector portion.
A segment of the cord portion (57) passes through the intersection of the axial and transverse cord channels. The segment of the cord portion passing through this intersection is fully jacketed. The individual conductors not being visible and not having begun their termination into the contacts.
The exterior surface of the connector portion also defines a transverse groove (60). The groove extends in a direction along the rear surface and the width of the connector portion. The groove extends in a direction along the transverse length of the transverse cord channel. The exterior opening of the axial cord channel intersects the groove. The groove extends from the intersection towards both the first and second sides and the first and second exterior openings opposite each other.
The groove comprises a plurality of pairs of outer edges (62). Each pair of outer edges converge towards each other. Each pair of edges converge towards the first and second exterior openings opposite each other and the first and second sides. Each pair of outer edges diverge away from each other towards the area of the intersection of the groove with the axial chord channel.
The depth of the groove decreases towards the first and second exterior openings opposite each other and the first and second sides. The depth of the groove increases towards the area of intersection with the axial cord channel.
The groove comprises flat groove surfaces (65). The flat groove surfaces extend from each pair of the groove's outer edges towards the face surface and the grooves depth.
A slot (67) is defined by the connector portion. A first portion of the slot (69) has an exterior slot opening which opens through the exterior of the rear surface and opens into the transverse cord channel. The axial cord channel intersects the first slot portion. This first slot portion extends from its intersection with the axial cord channel towards the first and second exterior openings opposite each other and the first and second sides.
The first slot portion opens into the axial cord channel from the first and second sides. The first slot portion extends in a direction along the rear surface and the width of the connector. This first slot portion extends in a direction along the transverse length of the transverse cord channel.
