Definitions

  • the present invention relates generally to connectors for connecting electrical cables and flexible conduits to electrical panels, and more particularly to an improved connector that allows easier insertion of a cable into the trailing end of a connector and of the connector into a panel.
  • junction boxes or panels have knock out holes or apertures where electrical cables are connected.
  • panel is used interchangeably to mean a junction box or a panel.
  • aperture is used since it generically applies to holes created in any of various manners. For example, a hole created when a pre-made knock out piece is removed from a wall of a panel is a true knock out hole or an aperture. But similarly, a hole made when a smaller hole is drilled and a knock out die- and-screw set is used to punch out a larger hole is also a knock out hole or aperture. And a hole made when drilled to the desired size is an aperture.
  • Armored and metallic electrical cables are supplied in different nominal sizes in accordance with typical applications. For example, in the United States the National
  • Armored cables (AC) and metal-clad cables (MC) have historically been connected to electrical junction boxes or panels with a tubular connector.
  • Such traditional connectors have a leading end with a threaded nose for insertion into an aperture in the panel, and then tightening of a locknut thereon to secure the connector to the panel.
  • Such connectors further have a trailing end with either a screw passing laterally through the connector wall or a strap and either one or two screws. By inserting a cable and then tightening the screw or screws, the cable is secured and retained in the connector.
  • a typical construction project can require hundreds to thousands of connectors and their connection.
  • One consideration for a contractor contemplating such a project is the cost of the connectors, which is usually based on the materials used, the energy, steps count, parts count, etc. needed to manufacture the connectors.
  • Another consideration for the contractor usually also is the cost of the labor to make the connections, both of the connector to the panel and of the cable into the connector.
  • snap engagement connectors have recently been introduced as a means to reduce the time and effort required for installation. Although these snap engagement connectors generally may partially or even fully eliminate the need to use tools for installation, they still typically require a lot of effort to snap into the apertures in panels. Alternately, if there is a need for a retrofit or disconnection of the connector, workers may then have to use tools to remove each snap engagement connector involved, which in turn will involve a lot of time and effort.
  • an improved connector for securing an electrical cable to an electrical junction box or panel.
  • Such an improved connector should preferably not require the use of any tools for installing or removing the connector, at either the leading or trailing end. Nonetheless, such an improved connector should preferably allow its leading end to connect quickly and securely to the panel as well as for its trailing end to quickly and securely accept connection of a cable.
  • Such a connector will vastly reduce the time and effort involved for installing or removing electrical cables in structure wiring.
  • the desired connectors must be additionally designed to work with standard electrical junction boxes panels, housings, etc., while allowing quick and easy connection with standard size knock out holes or apertures.

  • the two insertion tabs 22 can be the same in general shape. Each extends, as shown, from opposite sides of the base 20 at an angle of 90 degrees or less.
  • the insertion tabs 22 have a press section 34 that forms a fit/release button, described presently.
  • the press sections 34 can each have two side flanks 36 to close side openings in the connector 10.
  • the insertion tabs 22 are further each extended away from the base 20 and turned up at an angle of greater than 90 degrees, in this case at 155 degrees, to form a respective hook latch 38.
  • the hook latches 38 have two angled corners 40, as shown. As also shown, the corners 40 can optionally have a triangular or curved cutout between adjacent pairs to permit better grip on the inner wall of a panel 1.
  • the corners 40 can also operate to penetrate through a paint or oxidation layer on the inner wall, to reach an underling metal wall material of the panel 1 and thus provide better electrical conductivity and grounding.
  • the two clamping tabs 24, 26 can also have the same shape, but preferably there are minor differences to facilitate better engagement with the spiral or helix shaped sides of a cable 3.
  • Each clamping tab 24, 26 extends from an opposite side of the base 20 at an angle of about 90 degrees. In FIG. 3 the clamping tab 26 is clearly presented, whereas the clamping tab 24 is almost entirely hidden behind other structure.
  • Each clamping tab 24, 26 has a set of two inward bent prongs, e.g., prongs 42, 44 of clamping tab 26 (clamping tab 24 has a corresponding pair of prongs that are mostly hidden behind other structure in FIG. 3).
  • the respective prongs in each of these sets can also be the same in size and degree of inward bend, but preferably are slightly different, again to facilitate better engagement with the spiral or helix shaped sides of a cable 3, and thus better securing the cable 3 inside the connector 10 and providing better electrical conductivity for grounding.
  • the second major component of the connector 10 is the shell 14. It is rigid, typically also electrically conducting, and, as shown, it has a nominally octagonal cross section.

  • the chamfers 58 are formed on the outward side of each tong 56, and serve to guide the connector 10 inside the aperture 2 of a panel 1 as well as to create support for receiving the block 16.
  • the ramps 60 are formed on the inward side of each tong 56, extending in depth inside the shell 14 and ending at a sharp angle to permit a snap-lock engagement with the block 16.
  • the third major component of the connector 10 is the block 16. It has two guiding bodies 62 that match the contour of the shell 14 between its tongs 56.
  • the block 16 further has a middle joining wall 64 with a cylinder 66 that includes a through passage 68.
  • the block 16 is completed by a plurality of snapping legs 70 (four here, three visible in FIG. 3).
  • the spring ring 12 is inserted in a first operation into the through opening 52 of the shell 14 and then the block 16 is inserted in a second operation into the through opening 52 of the shell 14.
  • the first insertion operation includes inwardly displacing the press sections 34 of the insertion tabs 22 sufficient to permit passage of the insertion tabs 22 between the trailing bridges 48 of the shell 14. Once the spring ring 12 is brought to its final position in the shell 14, the inward displacement is stopped and outward spring action of the press sections 34 occurs, thus trapping the spring ring 12 in the shell 14. In this manner the press sections 34 are used as fit buttons during assembly (and can be used as release buttons for disassembly).
  • the second insertion operation includes snapping the block 16 into the sub-assembly of the shell 14 and spring ring 12.
  • the block 16 is passed into the through opening 52, with the snapping legs 70 of the block 16 each aligning with a corresponding tong 56 of the shell 14.
  • the snapping legs 70 slidingly engage with the ramps 60 of the tongs 56, until the block 16 is brought to its final position. Once the snapping legs 70 extend past the ramps 60 they snap outward within the shell 14, thus locking the block 16 within the sub-assembly of the shell 14 and spring ring 12.
  • the press sections 34 of the insertion tabs 22 are pressed, thus inwardly moving the hook latches 38 enough to pass the leading end 32 of the connector 10 into an aperture 2.
  • the insertion tabs 22 bounce back, outward, to grip into the inner wall of the panel 1.
  • the cable 3 is pushed through the hole 28 at the trailing end 30 of the connector 10, until the cable 3 abuts against the block 16, where it is then locked into place by the grip of the prongs (e.g., by the two prongs of clamping tab 24 and the prongs 42, 44 of clamping tab 26).

Finally, as shown, adjacent to the free tips 124 are side sections 126 (4 total, two clearly visible here) that are left unbent to act as stoppers and limit the protrusion of the connector 100 too far into an aperture 2.
  • connectors 10, 100 having major and minor variations have now been disclosed. These connectors 10, 100 save a lot of time and effort over traditional connectors and have other advantages over these and other snapping type connectors, such as eliminating the need for manual use of tools to connect or disconnect the subject connectors 10, 100.
  • the present invention offers a quick connect connector for an electrical junction box or panel that requires no tools for connection or removal of the connector. Moreover, it needs much less effort and force for installation or removal compared to the existing snapping connectors. Due to its unique design, there are large contact areas between the electrical junction box or panel, the connector, and the jacket of the electrical cable that in turn results in a very good electrical continuity and grounding.
