Claim 3

The terminal according to claim 1, wherein the terminal is for use with wires of a specified thickness, the blade parts (362, 363) defining heights at least equal to or greater than the thickness of the wires.

Claim 4

A terminal according to claim 1, wherein the slits have different respective lengths.

Claim 5

The terminal according to claim 3, wherein the lateral side is of stepped configuration for achieving said different heights.

Claim 6

A cramping connector for a plurality of branch wires (390) and a plurality of main wires (400), comprising: a plurality of terminals 360), each said terminal (360) having an elongate connecting strip (361) and each end of said strip being bent to define first and second parallel blade parts (362, 363), said first and second blade parts (362, 363) each having a pair of spaced apart blade portions (362a, 363a) defining a wire receiving slit (362a1, 363a1) therebetween, each said wire receiving slit (362a1, 363a1) defining a wire inserting direction and at least one wire engaging position along said wire inserting direction, said connecting strip having a longitudinal axis (361) being obliquely aligned relative to the blade parts (362, 363) such that said wire engaging positions of the respective blade parts (362, 363) are offset from one another in directions transverse to said wire inserting direction, and a housing (370, 380) for retaining the terminals (360) and for positioning the plurality of branch and main wires (390, 400) adjacent one another, the housing including means for pressing the branch wires (390) into the wire receiving slit (362a1) of the first blade part (362) and means for pressing the main wires (400) into the wire receiving slit (363a1) of the second blade Part (363), the housing (370, 380) further including means for permitting each of said main wires (400) to pass entirely therethrough and means (371c) for retaining ends of said branch wire (390) within said housing (370, 380).

Claim 7

A cramping connector for a plurality of branch wires (390) and a plurality of main wires (400), comprising: a plurality of terminals 360), each said terminal (360) having an elongate connecting strip (361) and each end of said strip being bent to define first and second parallel blade parts (362, 363), said first and second blade parts (362, 363) each having a pair of spaced apart blade portions (362a, 363a) defining a wire receiving slit (362a1, 363a1) therebetween, each said wire receiving slit (362a1, 363a1) defining a wire inserting direction and at least one wire engaging position along said wire inserting direction, said connecting strip having a longitudinal axis (361) being obliquely aligned relative to the blade parts (362, 363) such that said wire engaging positions of the respective blade parts (362, 363) are offset from one another in directions transverse to said wire inserting direction, and a housing (370, 380) for retaining the terminals (360) and for positioning the plurality of branch and main wires (390, 400) adjacent one another, the housing including means for pressing the branch wires (390) into the wire receiving slit (362a1) of the first blade part (362) and means for pressing the main wires (400) into the wire receiving slit (363a1) of the second blade Part (363), the housing (370, 380) further including means for permitting each of said main wires (400) to pass entirely therethrough and means (371c) for retaining ends of said branch wire (390) within said housing (370, 380).

Claim 8

The cramping connector according to claim 5, wherein the housing is configured for positioning the plurality of wires one over the other.

Claim 9

The cramping connector according to claim 5, wherein the housing comprises first and second casings (370, 380), the first casing (370) comprising means (371a) for retaining and positioning the terminals (360) therein, and the second casing (380) defining the means for pressing the wires.

Claim 10

A cramping connector according to claim 7, wherein the blade portions (212a, 213a; 215a, 216a; 218a, 219a; 362a, 363a) are obliquely arranged in the housing (220, 240; 370, 380).

Claim 11
