Abstract

A connection system for communication connectors. A first connector housing forms a front opening having an axis for receiving a second connector having a latch in the direction of the axis. The first connector housing has a retaining surface in the region of the front opening for cooperating with a part of the latch and defining a connected position for the second connector within the first connector housing. At least two resilient fingers project from a rear portion of the first connector housing toward the front opening, symmetrically with respect to the axis of the opening. Free ends of the fingers urge the second connector toward the connected position and restrain the second connector from deviating from the connected position during use. Optimal electrical performance of the mated connectors can then be maintained.

Claims

1. A connection system for communication connectors, comprising:

a first connector housing forming a front opening having an axis, for receiving a second connector including a latch along the direction of said axis;

the first connector housing forms a retaining surface in the region of the front opening, wherein the retaining surface defines a connected position at which the retaining surface cooperates with a part of the latch to restrain displacement of the second connector in a direction out of the first connector housing; and

a terminal housing joined to the first connector housing, the terminal housing having two resilient catches which are formed to project from opposite sides of the terminal housing and to engage corresponding sides of the first connector housing;

wherein said catches project toward the front opening of the first connector housing, and free ends of the catches are configured to cooperate with a nose part of the second connector to urge the second connector toward the connected position and to restrain the second connector from displacement further into the connector housing.

2. A connection system according to claim 1, wherein said catches extend generally in a common plane.

3. A connection system according to claim 2, wherein the common plane is substantially parallel to the axis of the front opening of the first connector housing.

4. A connection system according to claim 1, wherein said catches include hook-shaped free ends having inclined surfaces configured to confront the nose part of the second connector when the second connector is received in the front opening of the first connector housing.

5. A connection system according to claim 4, wherein said catches are dimensioned and arranged to deflect away from one another in response to advancement of the nose part of the second connector through said front opening, and the first connector housing includes a rear wall that defines a limit of travel of the second connector beyond the connected position inside the first connector housing.

6. A connection system according to claim 5, wherein the limit of travel is about 0.033 inches.

7. A connection system according to claim 1, wherein the first connector housing is a jack housing of a modular communication jack.

8. A connection system according to claim 1, wherein the first connector housing includes a resilient, inclined wedge piece or cam on an inside surface of the housing and located to confront a part of the second connector to urge the second connector toward the connected position.

9. A connection system according to claim 8, wherein the first connector housing is a jack housing of a modular communication jack.

10. A connection system according to claim 1, wherein the terminal housing has a front wall, and including a unitary resilient leaf spring disposed on the front wall to confront a part of the second connector to urge the second connector toward the connected position.

11. A connection system according to claim 10, wherein the first connector housing is a jack housing of a modular communication jack.

18. A connection system according to claim 7, wherein the free ends of the fingers are constructed and arranged to deflect toward and to abut one another in response to advancement of the second connector through said front opening, thus defining a limit of travel of the second connector beyond the connected position inside the first connector housing.

19. A connection system according to claim 18, wherein the limit of travel is about 0.033 inches.

12. A connection system for communication connectors, comprising:

a first connector housing forming a front opening having an axis, for receiving a second connector including a latch along the direction of said axis;

the first connector housing forms a retaining surface in the region of the front opening, wherein the retaining surface defines a connected position at which the retaining surface cooperates with a part of the latch to restrain displacement of the second connector in a direction out of the first connector housing; and

at least two resilient fingers fixed to a rear portion of the first connector housing and arranged to project toward the front opening symmetrically with respect to the axis of the front opening, wherein free ends of the fingers are configured to urge the second connector toward the connected position and to restrain the second connector from displacement further into the connector housing;

free ends of said fingers are configured to arc toward one another to confront a part of the second connector when the second connector is received in the front opening of the first connector housing; and

the free ends of the fingers are constructed and arranged to deflect toward and to abut one another in response to advancement of the second connector through said front opening, thus defining a limit of travel of the second connector beyond the connected position inside the first connector housing.

13. A connection system according to claim 12, wherein the limit of travel is about 0.033 inches.

14. A connection system for communication connectors, comprising:

a first connector housing forming a front opening having an axis, for receiving a second connector including a latch along the direction of said axis;

the first connector housing forms a retaining surface in the region of the front opening, wherein the retaining surface defines a connected position at which the retaining surface cooperates with a part of the latch to restrain displacement of the second connector in a direction out of the first connector housing; and

at least two resilient fingers fixed to a rear portion of the first connector housing and arranged to project toward the front opening symmetrically with respect to the axis of the front opening, wherein free ends of the fingers are configured to urge the second connector toward the connected position and to restrain the second connector from displacement further into the connector housing;

wherein the first connector housing is a jack housing of a modular communication jack; and

a number of equi-spaced parallel channels are formed in a portion of the jack housing to support associated contact wires for making electrical connections with corresponding contacts on a mating plug connector.

15. A connection system according to claim 14, wherein said fingers extend in a common plane.

16. A connection system according to claim 15, wherein the common plane is substantially parallel to the axis of the front opening of the first connector housing.

17. A connection system according to claim 14, wherein free ends of said fingers are configured to arc toward one another to confront a part of the second connector when the second connector is received in the front opening of the first connector housing.
