US5586905A — Insulation displacement electrical connector with…

Claim 1

Independent Claim 171 words

In an electrical connector assembly for terminating an insulated electrical wire having an inner conductor surrounded by insulation, the connector assembly including: housing means having a wire-receiving opening therein for receiving the insulated electrical wire; a terminal mounted in the housing means and having an insulation displacement slot adapted to displace the insulation of the wire and electrically engage the inner conductor to create an electrical connection therebetween; wherein the improvement comprises: integrally molded strain relief means located adjacent the connection within the wire-receiving opening of the housing means for surrounding and gripping the insulated wire substantially entirely thereabout, wherein the wire-receiving opening extends entirely through the housing means and said integrally molded strain relief means are positioned on both sides of the terminal within the opening adjacent the electrical connection to provide support to the electrical insulated wire in two locations longitudinally spaced along the wire on opposite sides of the terminal, whereby the strain relief means provide support to the insulated electrical wire and strain relieves the inner conductor.

Claim 2

Dependent Claim 171 words

In an electrical connector assembly for terminating an insulated electrical wire having an inner conductor surrounded by insulation, the connector assembly including: housing means having a wire-receiving opening therein for receiving the insulated electrical wire; a terminal mounted in the housing means and having an insulation displacement slot adapted to displace the insulation of the wire and electrically engage the inner conductor to create an electrical connection therebetween; wherein the improvement comprises: integrally molded strain relief means located adjacent the connection within the wire-receiving opening of the housing means for surrounding and gripping the insulated wire substantially entirely thereabout, wherein the wire-receiving opening extends entirely through the housing means and said integrally molded strain relief means are positioned on both sides of the terminal within the opening adjacent the electrical connection to provide support to the electrical insulated wire in two locations longitudinally spaced along the wire on opposite sides of the terminal, whereby the strain relief means provide support to the insulated electrical wire and strain relieves the inner conductor.

Claim 3

Dependent Claim 81 words

In an electrical connector assembly as set forth in claim 1, wherein said housing means is defined by a pair of dielectric housing halves which are relatively movable between an open condition, for insertion of the insulated wire thereinto, and a closed position, wherein the housing halves are positively latched together, and wherein the integrally molded strain relief means are operatively associated between the housing halves and support the insulated electrical wire when the housing halves are in their closed position.

Claim 4

Dependent Claim 36 words

In an electrical connector assembly as set forth in claim 2, wherein said housing halves are molded of plastic material, and including integrally molded hinge means between the housing halves to facilitate said relative movement therebetween.

Claim 5

Dependent Claim 42 words

In an electrical connector assembly as set forth in claim 2, wherein said strain relief means comprise two complementary flexible portions located on each of the housing halves to yield a total of four areas of support around the insulated electrical wire.

Claim 6

Dependent Claim 59 words

In an electrical connector assembly as set forth in claim 4, wherein said two complementary flexible portions are defined by a relatively thin membrane in the shape of a semi-circle having a vertical slot extending therethrough, whereby the flexibility of the flexible portions allows accommodation of and effective strain relief to a wide range of insulated electrical wire diameters.

Claim 7

Dependent Claim 152 words

In an electrical connector assembly for terminating an insulated electrical wire having an inner conductor surrounded by insulation, said connector assembly including: a housing having an opening into which the insulated electrical wire is insertable, a terminal mounted in the housing and having an insulation displacement slot within said opening adapted to displace the insulation of the wire to electrically engage the inner conductor of the wire, wherein the improvement comprises: flexible strain relief portions of the housing adapted to substantially entirely surround and grip the insulated wire at a location longitudinally spaced along the insulated wire from said insulation displacement slot of the terminal, wherein the opening extends entirely through the housing and the flexible strain relief portions are positioned within the opening on both sides of the terminal to provide support to the electrical insulated wire in two locations longitudinally spaced along the wire on opposite sides of the terminal.

Claim 8

Dependent Claim 152 words

In an electrical connector assembly for terminating an insulated electrical wire having an inner conductor surrounded by insulation, said connector assembly including: a housing having an opening into which the insulated electrical wire is insertable, a terminal mounted in the housing and having an insulation displacement slot within said opening adapted to displace the insulation of the wire to electrically engage the inner conductor of the wire, wherein the improvement comprises: flexible strain relief portions of the housing adapted to substantially entirely surround and grip the insulated wire at a location longitudinally spaced along the insulated wire from said insulation displacement slot of the terminal, wherein the opening extends entirely through the housing and the flexible strain relief portions are positioned within the opening on both sides of the terminal to provide support to the electrical insulated wire in two locations longitudinally spaced along the wire on opposite sides of the terminal.

Claim 9

Dependent Claim 30 words

In an electrical connector assembly as set forth in claim 6, wherein said housing is molded of plastic material amid said flexible strain relief portions comprises integrally molded portions thereof.

Claim 10

Dependent Claim 40 words

In an electrical connector assembly as set forth in claim 7, wherein said housing includes two parts connected by way of an integrally molded hinge, with said integrally molded flexible strain relief portions being on each of the two parts.

Claim 11

Dependent Claim 58 words

In an electrical connector assembly as set forth in claim 8, wherein two said flexible strain relief portions are provided on each part of the housing to define four gripping areas about the circumference of the insulated electrical wire, and wherein the flexible strain relief portions can effectively provide support to a range of insulated electrical wire diameters.
