Abstract

An example electrical connector includes a non-electrically-conductive housing carrying at least a pair of opposed flexible, electrically-conductive push-in type contacts. The contacts each having a first end configured to receive and grip an electrical conductor, and a second end having a contact portion to releasable electrically couple with a corresponding conductive strip housed on opposite sides of an upper rail of a corresponding low voltage direct current grid member. In one example, a strain relief mechanism is coupled to the housing and is adapted to mechanically couple to the inserted electrical conductor and to assist in retaining the inserted electrical conductor in the push-in type contact. The housing may also define at least a pair of first interior spaces enclosing the first end of each of the contacts and for receiving and gripping the electrical conductor.

Claims

1. An electrical connector for use with a low voltage, direct current grid member having a first side carrying a first conductive strip and a second side opposed to the first side carrying a second conductive strip, the electrical connector comprising:

a non-electrically-conductive housing having a first contact compartment, a second contact compartment, a first wire receiving compartment positioned adjacent to the first contact compartment, and a second wire receiving compartment positioned adjacent to the second contact compartment;

a first flexible, electrically-conductive push-in type contact disposed in the first contact compartment; and

a second flexible, electrically-conductive push-in type contact disposed in the second contact compartment;

wherein the first push-in type contact has a first end and a second end, wherein the first end of the first push-in type contact has a first contact portion which extends from the first contact compartment into the first wire receiving compartment and which is arranged to be cooperable with a first wall of the first wire receiving compartment to grip therebetween a first electrical conductor when inserted into the first wire receiving compartment, and wherein the second end of the first push-in type contact has a second contact portion which is positioned relative to the housing to electrically couple with the first conductive strip when the housing is releasably positioned upon the low voltage direct current grid member; and

wherein the second push-in type contact has a first end and a second end, wherein the first end of the second push-in type contact has a first contact portion which extends from the second contact compartment into the second wire receiving compartment and which is arranged to be cooperable with a first wall of the second wire receiving compartment to grip therebetween a second electrical conductor when inserted into the second wire receiving compartment, and wherein the second end of the second push-in type contact has a second contact portion which is positioned relative to the housing to electrically couple with the second conductive strip when the housing is releasably installed upon the low voltage direct current grid member.

2. An electrical connector as defined in claim 1, wherein the housing has first and second opposed side walls and wherein the first and second side walls of the housing cooperate with the low voltage direct current grid member to enclose the second end of each of the first and second push-in type contacts when the housing is releasably installed upon the low voltage direct current grid member.

3. An electrical connector as defined in claim 1, wherein the housing has a first aperture for directing the first conductor into the first wire receiving compartment and a second aperture for directing the second conductor into the second wire receiving compartment and wherein the housing further comprises a first conductor strain relief mechanism positioned adjacent to the first aperture and a second conductor strain relief mechanism positioned adjacent to the second aperture.

4. An electrical connector as defined in claim 3, wherein the housing, the first conductor strain relief mechanism, and the second conductor strain relief mechanism are integrally formed.

5. An electrical connector as defined in claim 3, wherein the first conductor strain relief mechanism and the second conductor strain relief mechanism each comprises an arcuate portion having ratchet teeth disposed thereon and a stationary ratchet configured to contact the ratchet teeth and retain the arcuate portion when the arcuate portion is moved towards the stationary ratchet.

6. An electrical connector as defined in claim 1, further comprising a cap for enclosing the first contact compartment, the second contact compartment, the first wire receiving compartment, and the second wire receiving compartment and for retaining the first and second push-in type contacts within the housing.

7. An electrical connector as defined in claim 6, wherein the cap has a first aperture for directing the first conductor into the first wire receiving compartment and a second aperture for directing the second conductor into the second wire receiving compartment and wherein the cap further comprises a first conductor strain relief mechanism positioned adjacent to the first aperture and a second conductor strain relief mechanism positioned adjacent to the second aperture.

8. An electrical connector as defined in claim 7, wherein the cap, the first conductor strain relief mechanism, and the second conductor strain relief mechanism are integrally formed.

9. An electrical connector as defined in claim 7, wherein the first conductor strain relief mechanism and the second conductor strain relief mechanism each comprises an arcuate portion having ratchet teeth disposed thereon and a stationary ratchet configured to contact the ratchet teeth and retain the arcuate portion when the arcuate portion is moved towards the stationary ratchet.

10. An electrical connector as defined in claim 1, wherein the housing further comprises a pair of flexible wings extending from the housing, wherein the wings are arranged to be disposed on the opposite sides of the low voltage direct current grid member below the conductive strips when the housing is releasably installed upon the low voltage direct current grid member.

11. An electrical connector as defined in claim 10, further comprising a protrusion on at least one the wings, the protrusions adapted to engage and pass through a keying slot provided to the low voltage direct current grid member.

12. An electrical connector as recited in claim 1, wherein the first wire receiving compartment is positioned adjacent to the second wire receiving compartment.

13. An electrical connector as recited in claim 12, further comprising a clamp element cooperable with the housing to maintain the housing installed upon the low voltage direct current grid member.

14. An electrical connector as recited in claim 10, wherein at least one of the wings is separately attachable to the housing.
