Abstract

Abstract The invention relates to an electrical connector, or wire connecting block, of the type for electrically interconnecting a set of first conductors to an associated set of second conductors. The connector comprises a dielectric housing defined by a pair of side walls and containing a plurality of through cavities therebetween. The cavities for slidably receiving a like plurality of slotted beam contacts are characterized by a first uniform width over a portion of its length, a second portion having a uniform width greater than the first uniform width, and an angled wall transition portion between the uniform portions. Externally, the housing is provided with a like plurality of thin walled sections along one of the side walls, where each said thin walled section is aligned with a corresponding angled wall transition portion within a given cavity. Into the cavity a slotted beam planar contact is received, where the contact comprises a mid body portion and a pair of opposing end portions each containing an insulation displacing slot for receiving a conductor. The mid body portion includes a lance struck therefrom and angled to abut the angled wall transition portion, whereby to secure the contact against movement in a first direction. Finally, after loading the contact into the cavity, the thin walled section is partially severed, such as by a sharp tool, to allow hinging movement of the section into its respective cavity adjacent said lances, whereby to secure the contact against movement in a second direction.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 210 words
An electrical connector of the type for electrically interconnecting a set of first conductors to an associated et of second conductors, the connector comprising a dielectric housing defined by a pair of side walls and containing a plurality of through cavities therebetween where the length of said cavities are characterized by a first uniform width over a portion of its length, a second portion having a uniform width greater than said first uniform width, and an angled wall transition portion between said uniform portions; and, a like plurality of thin walled sections along one of said side walls, where each said thin walled section is aligned with a corresponding angled wall transition portion within a given cavity, a slotted beam planar contact received in each said cavity, where said contact comprises a mid portion and a pair of opposing end portions each containing an insulation displacing slot for receiving a conductor, said mid portion having a lance struck therefrom and angled to abut said angled wall transition portion, whereby to secure said contact against movement in a first direction, and said thin walled sections being partially severed to allow hinging movement thereof into the respective cavities adjacent said lances, whereby to secure said contact against movement in a second direction.
Claim 2
Dependent Claim 210 words
An electrical connector of the type for electrically interconnecting a set of first conductors to an associated et of second conductors, the connector comprising a dielectric housing defined by a pair of side walls and containing a plurality of through cavities therebetween where the length of said cavities are characterized by a first uniform width over a portion of its length, a second portion having a uniform width greater than said first uniform width, and an angled wall transition portion between said uniform portions; and, a like plurality of thin walled sections along one of said side walls, where each said thin walled section is aligned with a corresponding angled wall transition portion within a given cavity, a slotted beam planar contact received in each said cavity, where said contact comprises a mid portion and a pair of opposing end portions each containing an insulation displacing slot for receiving a conductor, said mid portion having a lance struck therefrom and angled to abut said angled wall transition portion, whereby to secure said contact against movement in a first direction, and said thin walled sections being partially severed to allow hinging movement thereof into the respective cavities adjacent said lances, whereby to secure said contact against movement in a second direction.
Claim 3
Dependent Claim 52 words
The electrical connector according to claim 1, wherein the end portions of said slotted beam planar contact includes said insulation displacing slot at the end and an opening between said slot and said mid body portion, where the slot adjacent said opening is work hardened to control the width of said slot.
Claim 4
Dependent Claim 22 words
The electrical connector according to claim 1, wherein said first uniform width is dimensioned to slidably receive said slotted beam planar contact.
Claim 5
Dependent Claim 32 words
The electrical connector according to claim 1, wherein said thin walled section is the base of a recess configured to receive a complementary shaped tool to partially sever said thin walled section.
Claim 6
Dependent Claim 26 words
The electrical connector according to claim 4, wherein said tool includes an angled cutting tip which hingedly pushes said thin walled section against its respective lance.
