Abstract

An electrical connector for supplying power to a circuit board or the like. The electrical connector has a housing with contact receiving cavities extending from a wire-receiving face to a mating face. Alignment cavities are positioned adjacent the contact receiving cavities and extend from the mating face toward the wire-receiving face. Contacts are positioned in the contact receiving cavities. Each contact has a wire-receiving portion and a contact section. The wire-receiving portion has power wires terminated thereto, and the contact section is positioned in the contact receiving cavities proximate the mating face. A connector latch arm extends from the housing and has a latch projection provided proximate the mating face of the housing. The latch projection is movable relative to the housing.

Claims

1. An electrical connector comprising:

a housing having contact receiving cavities extending from a wire-receiving face to a mating face, alignment cavities positioned adjacent the contact receiving cavities, the alignment cavities extending from the mating face toward the wire-receiving face;

contacts positioned in the contact receiving cavities, the contacts having wire-receiving portions and contact sections, the contact sections being positioned in the contact receiving cavities proximate the mating face;

a connector latch arm extending from the housing, the connector latch arm having a latch projection proximate the mating face, the latch projection being movable relative to the housing; and

the contact receiving cavities having latch arm projections and retention shoulders which extend into securing sections of the contact receiving cavities, the latch arm projections and the retention shoulders cooperating with mounting shoulders of the contacts to retain the contacts in the contact receiving cavities, the latch arm projections being provided on contact latch arms which can be resiliently displaced to move the latch arm projections out of the contact receiving cavities, thereby allowing the contacts to be removed from the contact receiving cavities.

2. The electrical connector as recited in claim 1 wherein at least one contact receiving cavity has walls which define a mating contact receiving area, the walls having slots extending therethrough.

3. The electrical connector as recited in claim 2 wherein at least one contact is positioned in the at least one contact receiving cavity, the at least one contact

having resilient contact arms which align with the slots of the walls and which move into the slots of the walls when a mating connector is mated with the at least one contact.

4. The electrical connector as recited in claim 1 wherein a first at least one contact is a blade contact and a second at least one contact is a receptacle contact.

5. The electrical connector as recited in claim 1 wherein the wire-receiving portions have power wires terminated thereto.

6. An electrical connector comprising:

a housing having at least one receptacle contact receiving cavity and at least one blade receiving contact cavity extending from a wire-receiving face to a mating face, alignment cavities positioned adjacent the at least one receptacle contact receiving cavity and the at least one blade contact receiving cavity, the alignment cavities extending from the mating face toward the wire-receiving face, the at least one receptacle contact receiving cavity having walls which define a mating contact receiving area, the walls having slots extending therethrough;

a receptacle contact positioned in the at least one receptacle contact receiving cavity, the receptacle contact having a receptacle wire-receiving portion and receptacle contact section, the receptacle contact section being positioned in the at least one receptacle contact receiving cavity proximate the mating face;

a blade contact positioned in the at least one blade contact receiving cavity, the blade contact having a blade wire-receiving portion and a blade contact section, the blade contact section being positioned in the at least one blade contact receiving cavity proximate the mating face; and

a connector latch arm extending from the housing, the connector latch arm having a latch projection proximate the mating face, the latch projection being movable relative to the housing.

7. The electrical connector as recited in claim 6 wherein the at least one receptacle contact receiving cavity has a first latch arm projection and a first retention shoulder which extend into the at least one receptacle contact receiving cavity, the first latch arm projection and the first retention shoulder cooperate with a receptacle mounting shoulder of the receptacle contact to retain the receptacle contact in the at least one receptacle contact receiving cavity.

8. The electrical connector as recited in claim 7 wherein the first latch arm projection is provided on a first contact latch arm which can be resiliently displaced to move the first latch arm projection out of the at least one receptacle contact receiving cavity, thereby allowing the receptacle contact to be removed from the at least one receptacle contact receiving cavity.

9. The electrical connector as recited in claim 6 wherein the at least one blade contact receiving cavity has a second latch arm projection and a second retention shoulder which extend into the at least one blade contact receiving cavity, the second latch arm projection and the second retention shoulder cooperate with a blade mounting shoulder of the blade contact to retain the blade contact in the at least one blade contact receiving cavity.

10. The electrical connector as recited in claim 9 wherein the second latch arm projection is provided on a second contact latch arm which can be resiliently displaced to move the second latch arm projection out of the at least one blade contact receiving cavity, thereby allowing the blade contact to be removed from the at least one blade contact receiving cavity.

11. The electrical connector as recited in claim 10 wherein the receptacle contact has resilient contact arms which align with the slots of the walls and which move into the slots of the walls when a mating connector is mated with the receptacle contact.

12. The electrical connector as recited in claim 6 wherein the receptacle wire-receiving portion and the blade wire-receiving portion have power wires terminated thereto.

13. An electrical connector comprising:

a housing having at least one receptacle contact receiving cavity extending from a wire-receiving face to a mating face, at least one alignment cavity positioned adjacent the at least one receptacle contact receiving cavity, the at least one alignment cavity extending from the mating face toward the wire-receiving face, the at least one receptacle contact receiving cavity having walls which define a mating contact receiving area, the walls having slots extending therethrough; and

a receptacle contact positioned in the at least one receptacle contact receiving cavity, the receptacle contact having a receptacle wire-receiving portion and receptacle contact section, the receptacle contact section being positioned in the at least one receptacle contact receiving cavity proximate the mating face;

the receptacle contact has resilient contact arms which align with the slots of the walls and which move into the slots of the walls when a mating connector is mated with the receptacle contact.

14. The electrical connector as recited in claim 13 wherein the at least one receptacle contact receiving cavity has a first latch arm projection and a first retention shoulder which extend into the at least one receptacle contact receiving cavity, the first latch arm projection and the first retention shoulder cooperate with a receptacle mounting shoulder of the receptacle contact to retain the receptacle contact in the at least one receptacle contact receiving cavity.

15. The electrical connector as recited in claim 14 wherein the first latch arm projection is provided on a first contact latch arm which can be resiliently displaced to move the first latch arm projection out of the at least one receptacle contact receiving cavity, thereby allowing the receptacle contact to be removed from the at least one receptacle contact receiving cavity.

16. The electrical connector as recited in claim 13 wherein a connector latch arm extends from the housing, the connector latch arm having a latch projection proximate the mating face, the latch projection being movable relative to the housing.

17. The electrical connector as recited in claim 13 wherein the receptacle wire-receiving portion has a power wire terminated thereto.
