Abstract

An electrical connector includes a housing having a mating end, a rear end opposite the first end, and an exterior wall extending from the mating end to the rear end. The exterior wall includes a cavity extending between the mating and rear ends. A pull tab is received within the cavity. The pull tab is linearly movable within the cavity between the mating and rear ends of the housing. A latch is held on the housing and covers at least a portion of the pull tab, such that the pull tab slides between the latch and the housing. A first element on the pull tab and a second element on the latch interact to move the latch between open and closed positions in response to movement of the pull tab relative to the housing.

Claims

1. An electrical connector comprising:

a housing having a mating end, a rear end opposite the mating end, and an exterior wall extending from the mating end to the rear end, the exterior wall including a cavity extending between the mating and rear ends;

a pull tab received within the cavity, the pull tab being linearly movable within the cavity between the mating and rear ends of the housing;

a latch held on the housing and covering at least a portion of the pull tab, such that the pull tab slides between the latch and the housing;

a first element on the pull tab and a second element on the latch that interact to move the latch between open and closed positions in response to movement of the pull tab relative to the housing; and

a biasing mechanism being a helical spring attached to at least a portion of the pull tab and held between the housing and the at least a portion of the pull tab, the biasing mechanism biasing the pull tab to a position relative to the latch wherein the latch is in the closed position;

wherein the first element comprises an extension extending outwardly from the pull tab and the second element comprises an indentation within the latch for receiving the extension therein.

2. The connector of claim 1 further comprising travel limits provided on the pull tab and within the housing cavity, the travel limits cooperating with one another to define a range of motion over which the pull tab moves within the housing cavity.

3. The connector of claim 1 further comprising an extension extending outwardly from the pull tab and a slot provided within the housing and communicating with the housing cavity, the extension being received within the slot and being movable within the slot to define a range of motion over which the pull tab moves within the housing cavity.

4. The connector of claim 1, wherein the connector is a first connector and wherein the latch comprises a body extending from a first end to an opposite second end, the latch body first end comprising an extension configured to be received within an opening within a second connector to lock the first and second connectors together.

5. The connector of claim 1, wherein the rear end of the housing comprises an opening configured to receive an electrical cable.

6. The connector of claim 1, wherein the latch is received within a portion of the housing cavity.

7. The connector of claim 1, wherein the connector is an external serial attached small computer system interface (SCSI) connector.

8. An electrical connector assembly including a pair of connectors configured to be electrically connected to one another, the electrical connector assembly comprising:

first and second connector housings each having a mating end, the first and second connectors configured to be electrically connected to one another adjacent the respective first and second connector housing mating ends, the first connector housing having a rear end opposite the mating end and an exterior wall extending from the mating end to the rear end, the exterior wall including a cavity extending between the mating and rear ends of the first connector housing;

a pull tab received within the cavity, the pull tab being linearly movable within the cavity between the mating and rear ends of the first connector housing;

a latch held on the first connector housing, at least a portion of the pull tab between the latch and the first connector housing;

a first element on the pull tab and a second element on the latch that interact to cause the latch to move between an open and a closed position upon movement of the pull tab within the cavity; and

a biasing mechanism being a helical spring attached to at least a portion of the pull tab and held between the first connector housing and the at least a portion of the pull tab, the biasing mechanism biasing the pull tab to a position relative to the latch wherein the latch is in the closed position;

wherein the first element comprises an extension extending outwardly from the pull tab and the second element comprises an indentation within the latch for receiving the extension therein.

9. The assembly of claim 8 further comprising travel limits provided on the pull tab and within the first connector housing cavity, the travel limits cooperating with one another to define a range of motion over which the pull tab moves within the first connector housing cavity.

10. The assembly of claim 8 further comprising an extension extending outwardly from the pull tab and a slot provided within the first connector housing and communicating with the first connector housing cavity, the extension being received within the slot and being movable within the slot to define a range of motion over which the pull tab moves within the first connector housing cavity.

11. The assembly of claim 8, wherein the latch comprises a body extending from a first end to a second end, the latch body first end being adjacent the mating end of the first connector housing, the latch body first end comprising an extension configured to be received within an opening within the second connector to lock the first and second connectors together.

12. The assembly of claim 8, wherein the mating end of the first connector housing comprises an opening configured to receive an electrical cable.

13. The assembly of claim 8, wherein the latch is received within a portion of the first connector housing cavity.

14. The assembly of claim 8, wherein the first connector is an external serial attached small computer system interface (SCSI) connector.
