The present invention relates generally to electrical connectors, and more particularly to insulation displacement connectors used to connect conventional zipcord-type electrical wire to plug and play cabling.
Insulation displacement connectors (IDC) are commonly utilized for creating connections between insulated electrical wiring and various electrical components. While there are many varieties of IDCs, there are few which are specifically designed for plug and play connections and none which provide a compact, simple, repeatable and reliable IDC which allows trunk and branch wiring with varying connector intervals.
It is thus the object of the present invention to overcome the limitations and deficiencies of existing IDCs utilized for plug and play cabling and like applications, by providing a unique IDC in the form of a camlock electrical connector.
This and other objects are accomplished by the present invention, a camlock electrical connector for providing a secure watertight connection between electrical wiring and plug and play cabling. The electrical connector has a first connector member with a bottom platform having an opening and a wall upstanding from the platform. Pointed pin elements extend outwardly from the wall and a cable connector extends outwardly from and externally of the wall. A second connector member has a connector body with a fulcrum peg extending downwardly from the body. The peg is configured to be inserted into the opening in the platform, the second connector member with its peg being rotatable in relation to the first connector member. When the peg is inserted into the opening and electrical wiring is positioned between the wall of the first connector and the body of the second connector member, rotation of the second connection member and its peg in relation to the first connection member causes the pin elements to pierce the electrical wiring, thereby securing the wiring to the electrical connector.
The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.
Electrical connector 1 of the present invention comprises first connector member 2 and second connector member 30. Connector members 2 and 30 are configured to be joined in order to provide a secure watertight connection between zipcord electrical wiring and plug and play cabling.
First connector member 2 comprises platform 4 having opening 6 extending through the platform. Wall 8 is upstanding from platform 4 and has modified internal concave surface 10. Cantilevered wall 12 with inset notch 13 overhangs wall 8 and serves to lock connector member 2 with second connector 30, as is further described below. Sharply pointed gold-plated pin elements 14 and 16 extend outwardly from wall 8, in the direction of platform 4. Pin elements 14 and 16 are multi-pronged and angled to allow for increased surface area of the elements' conductors, allowing for a greater margin of error during the installation process. That is, if the installer fails to properly position the electrical wiring between first connector member 2 and second connector member 30, as described in further detail below, the unique orientation of pin elements 14 and 16 assists in assuring that an electrical connection will be made. Threaded cable connector 18 extends outwardly from and externally of wall 8. Through hole 39 with an Allen-key socket is provided for a mounting screw to affix electrical connector 1 to a desired surface. Hole 39 also allows for a means of stacking connectors 1a, via peg 34a, as illustrated in
Guide member 20 is located adjacent to wall 8. It has modified convex outer surface 22 which corresponds with concave surface 10 of wall 8. Channels 24 and 26 within guide member 20 have modified concave surfaces, configured to except electrical wiring within the guide member and, hence within first connector member 2. Slits 27 and 29 extending through channels 24 and 26 are provided for the placement of pin elements 14 and 16 through guide member 20. Guide member 20 acts as a grommet seal which enables electrical connector 1 to achieve an IP68 rating (submersible beyond one meter for thirty minutes).
Second connector member 30 comprises connector body 32, body interior surface 33, and fulcrum peg 34 which extends downwardly from the body. Cantilevered wall 36 with locking tab 38 overhangs connector body 32. Peg 34 of connector member 30 is configured to be inserted into opening 6 of connector member 2, which allows connector member 30 to be rotatable about connector member 2.
In use, connector member 30 is rotated about connector member 2 to a first, open position, creating open space 40 between the connector members, as seen best in
The present invention, as disclosed, is shown for plug and play output. However, it could also be designed to utilize a conventional zipcord input/output, or integrated into an electrical device, e.g. a light fixture; speaker, etc.
Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
