Abstract

An electrical connector includes a housing and a conductive contact member disposed in the housing. A first contact portion of the conductive contact member receives a blade contact of an electrical device and a second contact portion electrically engages an inserted electrical wire. A spring member is disposed in the housing and is connected to the contact member. A rotatable member is movable between first and second positions. When the rotatable member is in the second position the spring member secures an inserted wire in electrical engagement with the conductive contact member and prevents removal of the inserted wire. When the rotatable member is in the first position the spring member allows for removal of an inserted wire and allows for insertion of a wire in the housing.

Claims

1. An electrical connector, comprising:

a housing;

a conductive contact member disposed in said housing;

a biasing member disposed in said housing and connected to said contact member; and

a rotatable release member movable between first and second positions, when said release member is in said second position said biasing member secures a substantially fully inserted wire in electrical engagement with the conductive contact member and prevents removal of the inserted wire, and when said release member is in said first position said biasing member allows insertion of the wire in said housing and removal of the substantially fully inserted wire from said housing, wherein movement of said release member between said first and second positions moves said biasing member.

2. The electrical connector according to claim 1, wherein said release member is manually movable externally of said housing.

3. The electrical connector according to claim 1, wherein said housing has first and second openings for insertion of wires in a direction substantially parallel to one another.

4. The electrical connector according to claim 1, wherein said housing has first and second stop members to limit rotation of said rotatable member.

5. An electrical connector, comprising:

a housing;

a conductive contact assembly disposed in said housing and having a first contact portion for receiving a blade contact of an electrical device and a second contact portion for electrically engaging an inserted electrical wire;

a locking member movably disposed between first and second positions with respect to said second contact portion;

a biasing member disposed in said housing and disposed between said second contact portion and said locking member for biasing said locking member between said first and second positions; and

a release member rotatable between first and second positions,

when said release member is in said first position said locking member moves to said first position, compresses said biasing member and allows for substantial full insertion and removal of the substantially fully inserted electrical wire, and when said release member is in said second position said release member is spaced from said locking member and said biasing member moves said locking member to said second position, secures the inserted electrical wire between said locking member and said second contact portion and substantially prevents removal thereof.

6. The electrical connector according to claim 5, wherein said release member is manually rotatable externally of said housing.

7. The electrical connector according to claim 5, wherein said locking member moves in a direction substantially perpendicular to said second contact portion.

8. The electrical connector according to claim 5, wherein a stop member in said housing limits rotation of said release member.

9. The electrical connector according to claim 5, wherein the electrical wire is inserted through an opening in the housing.

10. The electrical connector according to claim 5, wherein said release member is spaced from the inserted wire.

11. The electrical connector according to claim 5, wherein notches in said second contact portion guide movement of said locking member between said first and second position.

12. The electrical connector according to claim 5, wherein said second contact portion passes through an opening in said locking member.

13. The electrical connector according to claim 12, wherein said locking member opening has a coined edge to facilitate engaging the inserted electrical wire.
