Total Claims: 9
Claim 1
Independent Claim
200 words
An insulation-piercing connector including a connector body made of an insulating material, a plurality of contacts made of a resilient conductive metal, each consisting of a contact element to be connected to a contact of a mating connector, a fixing element carried by said connector body and a U-shaped piercing terminal element extending from a surface of said connector body and embracing a wire between legs of the U-shaped element, said contacts being arranged staggered in at least two rows, and a cover made of an insulating material and formed with terminal element receiving grooves for receiving the U-shaped elements of said contacts, and when said cover is covered onto said connector body, said cover forcing wires into the U-shaped elements and embracing the wires between the cover and said connector body, wherein surfaces of said connector body for embracing the wires in conjunction with said cover are raising inclination surfaces from a side of the U-shaped piercing elements in one row toward above the U-shaped piercing elements in the other row to form alternately reversely inclined surfaces, and surfaces of said cover for embracing the wires are inclination surfaces auxiliary with said alternately inclined surfaces of the connector body.
Claim 2
Dependent Claim
200 words
An insulation-piercing connector including a connector body made of an insulating material, a plurality of contacts made of a resilient conductive metal, each consisting of a contact element to be connected to a contact of a mating connector, a fixing element carried by said connector body and a U-shaped piercing terminal element extending from a surface of said connector body and embracing a wire between legs of the U-shaped element, said contacts being arranged staggered in at least two rows, and a cover made of an insulating material and formed with terminal element receiving grooves for receiving the U-shaped elements of said contacts, and when said cover is covered onto said connector body, said cover forcing wires into the U-shaped elements and embracing the wires between the cover and said connector body, wherein surfaces of said connector body for embracing the wires in conjunction with said cover are raising inclination surfaces from a side of the U-shaped piercing elements in one row toward above the U-shaped piercing elements in the other row to form alternately reversely inclined surfaces, and surfaces of said cover for embracing the wires are inclination surfaces auxiliary with said alternately inclined surfaces of the connector body.
Claim 3
Dependent Claim
48 words
A connector as set forth in claim 1, wherein said connector body comprises a lower main part having said contacts of which U-shaped piercing elements extend from a surface of the lower main part and an upper part having said alternately inclined surfaces and piercing element passing apertures.
Claim 4
Dependent Claim
39 words
A connector as set forth in claim 1, wherein said inclined surfaces of at least one of said connector body and said cover are formed in the proximities of uppermost portions of the inclined surfaces with wire positioning recesses.
Claim 5
Dependent Claim
34 words
A connector as set forth in claim 1, wherein said inclined surfaces of at least one of said connector body and said cover are formed therealong with elongated supporting grooves for positioning the wires.
Claim 6
Dependent Claim
40 words
A connector as set forth in claim 1, wherein said inclined surfaces of said connector body and said cover are provided at their highest portions with piercing assisting projections, thereby elongating torn lengths of coating when used a flat cable.
Claim 7
Dependent Claim
15 words
A connector as set forth in claim 5, wherein said piercing assisting projections are triangular.
Claim 8
Dependent Claim
15 words
A connector as set forth in claim 5, wherein said piercing assisting projections are semicircular.
Claim 9
Dependent Claim
76 words
A connector as set forth in claim 1, wherein said contacts are arrange in four rows, in each group of two rows, the contacts are arranged staggered so that within a width of one piercing element are included two inclined surfaces inclined in the same direction and one inclined surface therebetween, and one piercing element of one group is shifted by a width of the inclined surface relative to one piercing element of the other group.
