Abstract

A junction box for electrical wiring includes one or more wiring connectors non-removably pre-mounted to side panels thereof. A variety of different connector types for supporting a variety of different types of electrical cables and wiring conduits may be provided in a single junction box. Removable plugs are provided to block the connector passageways, but are easily removed from those connectors that are to be used for wiring in a particular installation. Since built-in connectors of various types are provided, end-user installation time is reduced.

Claims (60)

1. A junction box for electrical wiring, comprising:

a. a first side panel and an opposing second side panel extending from a back panel to surround a junction box interior, the first and second side panels each having at least one wiring aperture formed therein;

b. a third side panel and a fourth side panel, the third and fourth side panels affixed to the back panel and to the first and second side panels on opposing sides of the junction box; and

c. a connector:

i. in one of the side panels,

ii. the connector defining a passageway for wiring into the junction box interior,

iii. wherein:

1) the connector extends outwardly from one of the side panels,

2) no portion of the connector extends into the junction box interior; and

3) the connector is a crimp-type flexible cable connector including:

a) a connector body portion defining the passageway opening into the junction box interior;

b. a bendable prong extending from the connector body portion, the bendable prong being configured to bend into the passageway of the crimp-type flexible cable connector to secure electrical wiring within the passageway; and

c. a transverse groove formed in the bendable prong, the transverse groove configured to facilitate bending of the bendable prong into the passageway.

2. The junction box of claim 1 wherein:

a. one of the side panels includes a collar extending outwardly therefrom,

b. the connector body portion of the crimp-type flexible cable connector is complementarily fit against the collar, and

c. the crimp-type flexible cable connector is non-removably mounted to the collar extending from one of the side panels by interlocking dimples formed between the connector body portion and the collar.

3. The junction box of claim 1 further including a second connector, the second connector being configured differently from the crimp-type flexible cable connector.

4. The junction box of claim 3 wherein the second connector is of a connector type selected from the group consisting of:

a. a double-bite flexible cable connector type; and

b. a conduit connector type.

5. The junction box of claim 4 wherein:

a. each of the connectors includes a cylindrical connector body portion defining the passageway, and

b. at least one of the connectors further includes a cylindrical throat insert situated within the passageway, the throat insert reducing a diameter of the connector body portion.

6. The junction box of claim 4 wherein the double-bite flexible cable connector includes:

a. a connector body portion having two slots on opposing sides of a fastener hole, the two slots and fastener hole extending between outer and inner surfaces of the connector body portion of the double-bite connector; and

b. a clip having two legs with curved ends, the legs being complementarily receivable through the two slots in the connector body portion of the double-bite connector.

7. The junction box of claim 6 wherein:

a. the fastener hole is threaded, and

b. the clip is securable to the connector by:

i. inserting the two legs through the two slots formed in the connector body portion of the double-bite connector and into the passageway, and

ii. engaging a threaded connector structure to the threaded fastener hole as the threaded connector structure enters the passageway.

8. The junction box of claim 3 wherein the second connector has:

a. a second connector body portion defining a second passageway into the junction box interior;

b. a threaded aperture formed in the second connector body portion; and

c. a threaded connector structure extending through the threaded aperture and into the second passageway.

9. The junction box of claim 1 wherein:

a. the connector body portion includes an axial slot formed therein, the axial slot extending between outer and inner surfaces of the connector body portion, and

b. the bendable prong is bendable into the passageway through the axial slot formed in the connector body portion.

10. The junction box of claim 9 wherein the bendable prong includes a first end and an opposing second end,

a. the first end being flexibly attached to one end of the axial slot,

b. the second end being bendable into the passageway with respect to the first end.

11. A junction box for electrical wiring including:

a. first, second, third, and fourth side panels extending from a back panel to define a junction box interior, and

b. at least one crimp-type flexible cable connector extending from one of the side panels, the crimp-type flexible cable connector including:

i. a connector body portion defining a passageway opening into the junction box interior,

1) the connector body portion including at least one axial slot formed therein,

2) the axial slot extending between outer and inner surfaces of the connector body portion;

ii. at least one bendable prong flexibly affixed to the connector body portion at one end of the axial slot, the bendable prong being bendable through the axial slot and into the passageway defined by the connector body portion; and

iii. a transverse groove formed in the bendable prong, the transverse groove configured to facilitate bending of the bendable prong into the passageway.

12. The junction box of claim 11 wherein:

a. one of the side panels includes a cylindrical collar extending out from one of the side panels away from the junction box interior,

b. the connector body portion is complementarily fit about the collar, and

c. the connector body portion and collar include interlocking dimples formed therebetween, the interlocking dimples non-removably mounting the connector body portion to one of the side panels.

13. The junction box of claim 12 further including a double-bite flexible cable connector having:

a. a connector body portion having two slots formed therein, the two slots extending between outer and inner surfaces of the connector body portion of the double-bite connector; and

b. a u-shaped clip having two legs with curved ends,

i. the legs being complementarily receivable through the two slots in the connector body portion of the double-bite connector and into the passageway,

ii. the curved ends being complementary to a cable extending into the junction box interior via the passageway formed by the connector body portion of the double-bite connector.

14. The junction box of claim 13 wherein no portion of the double-bite flexible cable connector extends into the junction box interior.
