Abstract

A connector guide mounted in front of a receptacle connector is provided with a latch that engages a connector mounted on a circuit board when a mating connector is inserted into the connector on the circuit board. The guide is separate from the plug connector and serves to align contact surfaces and provide strain relief to the receptacle connector.

Claims

1. A connector assembly, comprising:

a connector housing having first and second sides, a top surface, a bottom surface, a front side and a back side, said connector housing including a plurality of electrical contacts that are accessible at the front side by extending an opposing mating connector through a first geometric plane that lies in front of the connector housing front side, the first geometric plane being orthogonal to the first and second sides but not extending beyond said first and second sides, top and bottom;

a connector guide including first and second sides, each side having top and bottom edges and front and back edges, each of said sides having a first height between its top and bottom edges and a first width between its front and back edges, said first and second sides being separated from each other by a first separation distance;

a top having first and second side edges and front and rear edges, the top first side edge being joined to said top edge of said first side, said top second side edge being joined to said top edge of said second side; and

,

a press arm formed as part of the guide, the press arm extending away from said guide top rear edge for engaging the mating connector within said connector guide, said connector guide not contacting said connector housing and being located forward of the first geometric plane, wherein said press arm includes a catch portion, said press arm extending at an angle such that said catch portion is positioned rearwardly of and below said top rear edge, above a top of said mating connector, said press arm biasing said catch portion into engagement with a corresponding recess formed in said mating connector, when said mating connector is inserted within said guide.

2. The connector assembly of claim 1, wherein said catch portion is located proximate to a distal end of said press arm.

5. The connector assembly of claim 1, wherein at least one of the first and second planar sides has at least one attachment post extending orthogonally away from the bottom edge of the at least one first and second planar sides.

6. The connector assembly of claim 1, wherein the first and second planar sides are orthogonal to the top, forming a U-shaped channel that can envelop a plug connector on three sides when a connector plug is within the guide and engaging said connector receptacle.

7. The connector assembly of claim 1, wherein said guide is formed, from sheet metal.

8. The connector assembly of claim 1, wherein said guide has an inverted U-shaped configuration when viewed from an end thereof.

3. The connector assembly of 1, further including a side locking latch, formed in the first planar side and extending toward the second planar side, the side locking latch engaging a corresponding plug connector side detent when a plug connector when a connector plug is within the guide and engaging said connector receptacle.

4. The connector assembly of 1, wherein said first side includes a connector engagement tab formed by stamping first planar side and cantilevered inwardly from said first side toward said second side, the connector engagement tab engaging a corresponding detent in a mating plug connector inserted into said guide thereby holding said mating plug connector within said guide when a mating plug connector is inserted within said guide.

9. A guide that is mountable to a printed circuit board for guiding a plug connector into engagement with an opposing mating connector that is separately mounted to the circuit board and spaced away from the guide on said circuit board, said guide comprising:

first and second sides, each side having top and bottom edges and front and back edges, each of said sides having a first height between the top and bottom edges thereof and a first width between the front and back edges thereof, said first and second sides being separated from each other by a first distance;

a top having first and second side edges and front and rear edges, the top first side edge being joined to said top edge of said first side, said top second side edge being joined to said top edge of said second side, such that when said guide is mounted to said circuit board, it has an inverted U-shape without any bottom interconnecting said first and second sides together when viewed from an end thereof and it defines a hollow channel between said top and said circuit board which receives the plug connector therein, when said plug connector is mated to the opposing mating connector; and

,

a press arm formed as part of the guide, the press arm being disposed along said guide top rear edge and extending in a cantilevered fashion away from said guide top rear edge at an angle such that an end of said press arm is positioned rearwardly of and below said guide top rear edge and above a top of said mating connector, whereby, when said plug connector is inserted within said guide, said press arm contacts an opposing surface of said plug connector.

10. The guide of claim 9, wherein said guide is formed form sheet metal.

11. The guide of claim 10, wherein at least one of said first and second sides of said guide includes a latch member that extends inward into said channel.

12. The guide of claim 10, wherein said first and second sides include posts extending therefrom for mounting said guide to said circuit board.
