Wiring connector

Claim 2

The connector defined in claim 1 wherein said distance-pieces are disposed across the ends of said side walls of said clamping member and comprise end portions bent at right angles to provide a slideway-forming gaP between the inner faces of said bent portions and the outer faces of said side walls.

Claim 3

The connector defined in claim 2 wherein said strap has lateral wings and said clamping member with the distance-pieces assembled thereto is adapted to be fitted by sliding on the wings of said strap for clamping the wires therebetween.

Claim 4

The connector defined in claim 3 wherein the side walls of said clamping member comprise each at least one window for assembling said strap with said clamping member by setting a portion of the strap into the windows of the clamping member juxtaposed therewith.

Claim 5

The connector defined in claim 4 wherein said strap has its wings normally projecting somewhat above the top edges of said clamping member to permit the pulling of said wings while pressing said clamping member against the wires disposed therebetween, and subsequently cutting off the excess portions of said strap wings by using said top edges as counter-blades.

Claim 6

The connector defined in claim 5, wherein said windows have bevelled edges, with the horizontal edges in counter-taper relationship for preventing any undesired disassembling of said strap and clamping member.

Claim 7

An electric wiring connector comprising a U-shaped strap and a U-shaped clamping member disposed in parallel relationship, said clamping member being shallower than, and fitted into, said strap, and adapted to be used for pressing the wires to be connected in the bottom of said strap, said bottom comprising reinforcing ribs and a central hole for receiving a branch wire extending at right angles to the wires clamped longitudinally in the main portion of the device, said strap having a concave bottom and said clamping member a convex bottom to accomodate the wires therein, wherein the vertical edges of the vertical side walls of said clamping member are bent at right angles and the corresponding edges of said strap are formed with serrations adapted in the assembled condition of said strap and clamping member to engage said vertical edges of said clamping member and to be retained therein by simply setting said vertical edges against said serrations.

Claim 8

An electric wiring connector comprising a U-shaped strap and a U-shaped clamping member disposed in parallel relationship, said clamping member being shallower than, and fitted into, said strap, and adapted to be used for pressing the wires to be connected in the bottom of said strap, said bottom comprising reinforcing ribs and a central hole for receiving a branch wire extending at right angles to the wires clamped longitudinally in the main portion of the device, said strap having a concave bottom and said clamping member a convex bottom to accomodate the wires therein, wherein the vertical edges of the vertical side walls of said clamping member are bent at right angles and the corresponding edges of said strap are formed with serrations adapted in the assembled condition of said strap and clamping member to engage said vertical edges of said clamping member and to be retained therein by simply setting said vertical edges against said serrations.

Claim 9

Connector as set forth in claim 7, wherein the strap and clamping member assembly is reinforced by performing a cold welding, such as molecular compression welding, therebetween at suitable locations.

Claim 10

An electric wiring connector comprising a U-shaped strap and a U-shaped clamping member disposed in parallel relationship, said clamping member being shallower than, and fitted into, said strap, and adapted to be used for pressing the wires to be connected into the bottom of said strap, said bottom comprising reinforcing ribs and a central hole for receiving a branch wire extending at right angles to the wires clamped longitudinally in the main portion of the device, said strap having a concave bottom and said clamping member a convex bottom to accomodate the wires therein, wherein the vertical edges of the vertical side walls of said clamping member are bent twice at right angles in order to constitute slideways for receiving the corresponding edges of said strap formed with notches adapted in the assembled condition of said strap and clamping member to engage said vertical slideways of said clamping member and to be retained therein by simply setting said bent vertical edges of said clamping member against the vertical edges of said strap.

Claim 11

An electric wiring connector comprising a U-shaped strap and a U-shaped clamping member disposed in parallel relationship, said clamping member being shallower than, and fitted into, said strap, and adapted to be used for pressing the wires to be connected into the bottom of said strap, said bottom comprising reinforcing ribs and a central hole for receiving a branch wire extending at right angles to the wires clamped longitudinally in the main portion of the device, said strap having a concave bottom and said clamping member a convex bottom to accomodate the wires therein, wherein the vertical edges of the vertical side walls of said clamping member are bent twice at right angles in order to constitute slideways for receiving the corresponding edges of said strap formed with notches adapted in the assembled condition of said strap and clamping member to engage said vertical slideways of said clamping member and to be retained therein by simply setting said bent vertical edges of said clamping member against the vertical edges of said strap.

Claim 12

Method of assembling the elements of an electric connector comprising a U-shaped strap and a U-shaped clamping member disposed in parallel relationship, said clamping member being shallower than, and fitted into, said strap, with the wires to be connected disposed therebetween, which comprises the steps of pulling the upper edges of the side wings of said strap which project above the top edges of the side walls of said clamping member while exerting a suitable pressure against said clamping member, and cutting off the excess metal of said strap by using said top edges as counter-blades.

Claim 13

Method of assembling the elements of an electric connector comprising a U-shaped strap and a U-shaped clamping member disposed in parallel relationship, said clamping member being shallower than, and fitted into, said strap, with the wires to be connected disposed therebetween, which comprises the steps of pulling the upper edges of the side wings of said strap which project above the top edges of the side walls of said clamping member while exerting a suitable pressure against said clamping member, and cutting off the excess metal of said strap by using said top edges as counter-blades.
