Electrical wiring bushing with strain relief

Claim 2

A bushing to protect and retain an electric wire passing through an aperture in a side of an electrical box comprising: a first body portion adapted to be received in an aperture of an electrical box, said first body portion having an open slot running parallel to its axis, a second body portion having an open slot running parallel to its axis, a connection portion having an open slot running parallel to its axis connecting said first and second body portions to align the axes and said slots of said first and second body portions and said connection portion whereby said aligned open slots are adapted to receive an electric wire after said first body portion is received in an aperture, and retaining means connected to only one of said body portions by fitting across its open slot, said retaining means being adapted to be placed in said one body portion after said first body portion is received in the aperture and being adapted to hold an electric wire in the aligned open slots of the bushing.

Claim 3

The invention if claim 1 wherein; said first body portion has means adapted to engage a portion of an outer periphery of the aperture when said first body portion is physically deformed by reducing its diameter to allow said first body portion to be placed into the aperture and thereafter said first body portion resiliently moves outward to engage the periphery of the aperture.

Claim 4

The invention of claim 2 wherein; said connection portion partially connects said first and second body portions whereby said second body portion can be physically deformed to remove said retaining means from the slot without changing the shape of said first body portion.

Claim 5

The invention of claim 1 wherein, said retaining means comprises: a plug member adapted to be received in an opening in said second body portion whereby said plug member is adapted to hold an electrical wire in said slot of said second body portion, and said connection portion partially connects said first and second body portions whereby said second body portion can be deformed without affecting said first body portion to remove said plug member.

Claim 6

The invention of claim 4 wherein; said second body portion is rigid enough to require a tool to be deformed to remove said plug member.

Claim 7

The invention of claim 1 wherein; said retaining means comprises a gate-like plug member adapted to be guided into a recess in said second body portion crosswise of its axis to hold the wire in said slot, said plug member and said recess having cooperating locking means on their contacting surfaces for holding said plug member in said recess, and said connection portion having a relief slot to provide only partial connection between said first and second body portions whereby said second body portion can be deformed to enlarge said recess to disengage said locking means to remove said plug member without affecting said first body portion and its adapted position in the aperture of the box.

Claim 8

A bushing to protect and retain an electrical wire passing through an aperture in a side of an electrical box wherein the side has an open slot connected to the aperture through which a wire can be passed to the aperture comprising: a first body portion adapted to be connected to an electrical box by being received into the aperture of the box, said first body portion having an open slot running parallel to its axis adapted to align with the slot of the box when said first portion is received by the aperture, a second body portion having an open slot running parallel to its axis, a connection portion having an open slot therein, said connection portion connecting said first and second body portions to align said open slots whereby said slots are adapted to receive an electric wire after said first body portion is received by the aperture, the wire being passed through said aligning open slots in the side of the box and said first, second and connection portions, and retaining means connected to one of said body portions by being received across its open slot after said first body portion is received by the aperture, said retaining means being adapted to hold the electric wire in said aligned open slots of the bushing.

Claim 9

A bushing to protect and retain an electrical wire passing through an aperture in a side of an electrical box wherein the side has an open slot connected to the aperture through which a wire can be passed to the aperture comprising: a first body portion adapted to be connected to an electrical box by being received into the aperture of the box, said first body portion having an open slot running parallel to its axis adapted to align with the slot of the box when said first portion is received by the aperture, a second body portion having an open slot running parallel to its axis, a connection portion having an open slot therein, said connection portion connecting said first and second body portions to align said open slots whereby said slots are adapted to receive an electric wire after said first body portion is received by the aperture, the wire being passed through said aligning open slots in the side of the box and said first, second and connection portions, and retaining means connected to one of said body portions by being received across its open slot after said first body portion is received by the aperture, said retaining means being adapted to hold the electric wire in said aligned open slots of the bushing.

Claim 10

The invention of claim 7 wherein; said retaining means comprises: a plug member cooperating with said one body portion, said plug member having a projection adapted to close the open slot in the side of the box.

Claim 11

The invention of claim 8 wherein; said second body portion has internal grooves on each side of its slot for receiving said plug member, and said outer edges of said plug member and a surface of each of said grooves have cooperating means for locking said plug member in place with sufficient force adapted to hold a wire in said open slots.

Claim 12

The invention of claim 9 wherein; said connection portion has relief slots to allow partial movement of said sides of said second body portion to disengage said means for locking said plug member when removal of said plug member is desired.

Claim 13

The invention of claim 1 wherein; said retaining means has means for locking said bushing to prevent its rotation when the bushing is placed in the aperture of the box.

Claim 14

The invention of claim 1 wherein; said retaining means provides a cover for said open slot of said one body portion to enclose the wire.
