Abstract
Abstract An electrical connector which includes a built-in indicator light arrangement is arranged such that the light source is positioned away from the front face of the connector through which the light is to be viewed, the light being directed from the light source to the front face by a light guide, which can either be formed by making the connector itself of a transparent material and including light reflecting or refracting surfaces as needed to direct the light to the front face of the connector, or by including a discrete waveguide placed in a passage which extends from the indicator light-containing cavity to the front face of the connector, and which includes appropriate light reflecting or refracting surfaces.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
In a connector, comprising: a housing; at least one electrical connector contact positioned in the housing; and at least one indicator light, the improvement wherein: the indicator light is positioned at a rear portion of the housing which is remote from a face of the housing through which the light is to be viewed, and wherein the connector further comprises discrete light guide means for guiding light from the indicator light to said face, wherein the housing is made of a transparent material and the indicator light is positioned such that light from the indicator light travels through said rear portion to reach said face, and wherein the indicator light is positioned in a cavity extending parallel to said face and said light guide means comprises an end portion engaged with a top surface of said cavity, said end portion being at an angle relative to the indicator light to cause light emitted by the indicator light to be diffracted towards said face of the housing.
Claim 2
Dependent Claim
166 words
In a connector, comprising: a housing; at least one electrical connector contact positioned in the housing; and at least one indicator light, the improvement wherein: the indicator light is positioned at a rear portion of the housing which is remote from a face of the housing through which the light is to be viewed, and wherein the connector further comprises discrete light guide means for guiding light from the indicator light to said face, wherein the housing is made of a transparent material and the indicator light is positioned such that light from the indicator light travels through said rear portion to reach said face, and wherein the indicator light is positioned in a cavity extending parallel to said face and said light guide means comprises an end portion engaged with a top surface of said cavity, said end portion being at an angle relative to the indicator light to cause light emitted by the indicator light to be diffracted towards said face of the housing.
Claim 3
Dependent Claim
27 words
A connector as claimed in claim 1, wherein said cavity is exposed at sides of the connector to facilitate insertion of the indicator light into the connector.
Claim 4
Dependent Claim
27 words
A connector as claimed in claim 1, wherein said cavity has extending transversely therefrom passages for accommodating leads of the indicator light without bending of the leads.
Claim 5
Dependent Claim
29 words
A connector as claimed in claim 1, wherein said cavity is exposed at a top surface of the housing to facilitate insertion of the indicator light into the housing.
Claim 6
Dependent Claim
26 words
A connector as claimed in claim 1, wherein said cavity has extending therefrom passages for accommodating leads of the indicator light without bending of the leads.
Claim 7
Dependent Claim
177 words
In a connector, comprising: a housing; at least one electrical connector contact positioned in the housing; and at least one indicator light, the improvement wherein: the indicator light is positioned at a rear portion of the housing which is remote from a face of the housing through which the light is to be viewed, and wherein the connector further comprises discrete light guide means for guiding light from a rear portion of said housing to said face, wherein the housing is made of a transparent material and the indicator light is positioned such that light from the indicator light travels through said rear portion to reach said face, and the discrete light guide means has an angled surface at one end for causing said light to be directed towards said face and a second end of the discrete light guide means has planar surfaces molded at different angles into said face so as to cause light exiting said face after travelling through said transparent material from said rear portion of the connector to disperse and facilitate visibility.
Claim 8
Dependent Claim
177 words
In a connector, comprising: a housing; at least one electrical connector contact positioned in the housing; and at least one indicator light, the improvement wherein: the indicator light is positioned at a rear portion of the housing which is remote from a face of the housing through which the light is to be viewed, and wherein the connector further comprises discrete light guide means for guiding light from a rear portion of said housing to said face, wherein the housing is made of a transparent material and the indicator light is positioned such that light from the indicator light travels through said rear portion to reach said face, and the discrete light guide means has an angled surface at one end for causing said light to be directed towards said face and a second end of the discrete light guide means has planar surfaces molded at different angles into said face so as to cause light exiting said face after travelling through said transparent material from said rear portion of the connector to disperse and facilitate visibility.
Claim 9
Dependent Claim
141 words
In a connector, comprising: a housing; at least one electrical connector contact positioned in the housing; and at least one indicator light, the improvement wherein: the indicator light is positioned at a rear portion of the housing which is remote from a face of the housing through which the light is to be viewed, wherein the connector further comprises discrete light guide means for guiding light from the indicator light to said face, wherein said discrete light guide means is a discrete waveguide positioned in a passage extending between said face and the indicator light is positioned in a cavity which communicates with said passage to allow light from the indicator light to enter the waveguide, and wherein said waveguide includes a portion having an angled surface for causing light emitted by the indicator light to be reflected towards said face.
Claim 10
Dependent Claim
141 words
In a connector, comprising: a housing; at least one electrical connector contact positioned in the housing; and at least one indicator light, the improvement wherein: the indicator light is positioned at a rear portion of the housing which is remote from a face of the housing through which the light is to be viewed, wherein the connector further comprises discrete light guide means for guiding light from the indicator light to said face, wherein said discrete light guide means is a discrete waveguide positioned in a passage extending between said face and the indicator light is positioned in a cavity which communicates with said passage to allow light from the indicator light to enter the waveguide, and wherein said waveguide includes a portion having an angled surface for causing light emitted by the indicator light to be reflected towards said face.
