Abstract

A housing of a fiber optic connector such as an MT-RJ connector has a greater surface area and ridges for improved handling and grasping. A door is provided on a fiber optic connector socket to block light leakage from the socket. The door is compact and does not interfere with neighboring devices while closed. The connector has a housing that centers the ferrule and keeps it in a position for precise alignment with the opposing ferrule. A pin retainer is designed to allow insertion and removal of alignment pins in the field without the need for removing the connector from the fiber optic, so that male connectors can be connected to female connectors and vice-versa.

Claims

1. A socket for receiving a fiber optic connector housing, said socket having forward and rearward directions, upward and downward directions transverse to the forward and rearward directions and lateral directions transverse to the other said directions, said socket defining a bore extending in said forward and rearward directions, said bore having a main portion and a keyway extending along the top of the main portion, said keyway having lateral dimensions less than the lateral dimensions of the main portion, said socket having an exterior profile including a principal portion having a first width and a top portion having a second width less than said first width, said top portion and said principal portion cooperatively defining a pair of ledges extending axially on opposite sides of said top portion, said main portion of said bore being disposed in said principal portion of said exterior shape, said keyway extending in said top portion wherein said bore is adapted to receive an MT-RJ connector hosing.

2. A socket as claimed in claim 1, wherein said socket has an opening at the rearward end of the socket for insertion of a fiber optic connector housing into said bore and wherein said socket has a panel engaging portion at the forward end of the socket and a pair of mounting lugs projecting upwardly and downwardly from the panel engaging portion.

3. A socket as claimed in claim 1, wherein said first width is approximately 9.3 mm and said exterior profile including said principal portion and said top portion has a height of 10 mm.

4. A socket as claimed in claim 1 has a top wall overlying said keyway and a latch pocket extending downwardly through the top wall.

5. A socket as claimed in claim 4, wherein said latch pocket has a forwardly-facing catch surface intersecting the keyway portion of the bore and wherein said top wall defines a top interior surface including a ramp surface sloping downwardly in the forward direction and extending from the rear end of the socket to the vicinity of the latch pocket and catch surface.
