Locking device and method for use with a multi-fiber push on (MPO) connector module to prevent the MPO connector module from being decoupled from a receptacle
View Patent ↗A locking device is provided that is configured to be attached to the MPO connector module and placed in a locking state that prevents the MPO connector module from being decoupled from the receptacle. The locking device may be a locking clip that is configured to be inserted into a keying slot formed in an MPO connector module. When the locking clip is inserted into the keying slot and placed in a locking state, the locking clip prevents the MPO connector module from being decoupled from the receptacle. If the locking clip is placed in an unlocking state, a tool or fingers can be used to extract the locking clip from the keying slot, thereby making it possible to decouple the MPO connector module from the receptacle.
1. A locking device for use with a multi-fiber push on (MPO) connector module for preventing the MPO connector module from being decoupled from a receptacle, the locking device comprising:
a clip with a tongue portion having a proximal end and a distal end and a curved portion having a proximal end and a distal end, wherein the proximal end of the tongue portion and the distal end of the curved portion are joined together, and wherein the tongue portion is configured to be inserted into a keying slot of the MPO connector module, the clip configured to be inserted into the keying slot of the MPO connector module in such a way that the clip prevents the MPO connector module from being decoupled from the receptacle.
2. The locking device of claim 1 , wherein the clip is a spring clip that is configured to be placed in a locking state and an unlocking state, wherein in the locking state, the spring clip exerts a force on a collar of the MPO connector module that prevents the collar from sliding such that the collar is held in a position that prevents one or more latching elements of the receptacle from disengaging from one or more latching elements of the MPO connector module.
3. The locking device of claim 2 , wherein the curved portion of the spring clip is generally U-shaped, and wherein in the locking state, the proximal end of the generally U-shaped portion abuts a forward surface of an outer housing of the MPO module and the distal end of the generally U-shaped portion abuts an end of the collar, and wherein the abutment of the proximal end of the generally U-shaped portion with the forward surface of the outer housing and the abutment of the distal end of the generally U-shaped portion with the end of the collar creates a spring force that biases the collar in a direction toward the receptacle to thereby hold the collar in said position that prevents one or more latching elements of the receptacle from disengaging from one or more latching elements of the MPO connector module.
4. The locking device of claim 3 , wherein the spring clip comprises sheet metal.
5. The locking device of claim 3 , wherein in the unlocking state, at least the distal end of the spring clip is retained within the keying slot of the MPO connector module until a user removes the spring clip from the MPO connector module.
6. A method for preventing a multi-fiber push on (MPO) connector module from being decoupled from a receptacle, the method comprising:
providing a clip with a tongue portion having a proximal end and a distal end and a curved portion having a proximal end and a distal end, wherein the proximal end of the tongue portion and the distal end of the curved portion are joined together, and wherein the tongue portion is configured to be inserted into a keying slot of the MPO connector module;
attaching the clip to the keying slot of the MPO connector module in such a way that the clip prevents the MPO connector module from being decoupled from the receptacle.
7. The method of claim 6 , wherein the clip is a spring clip that is configured to be placed in a locking state and an unlocking state, wherein in the locking state, the spring clip exerts a force on a collar of the MPO connector module that prevents the collar from sliding such that the collar is held in a position that prevents one or more latching elements of the receptacle from disengaging from one or more latching elements of the MPO connector module.
8. The method of claim 7 , wherein the curved portion of the spring clip is generally U-shaped, and wherein the spring clip is placed in the locking state by placing the proximal end of the generally U-shaped portion in abutment with a forward surface of an outer housing of the MPO module, and wherein the abutment of the proximal end of the generally U-shaped portion with the forward surface of the outer housing causes the distal end of the generally U-shaped portion to bias the collar in a direction toward the receptacle to thereby hold the collar in said position that prevents one or more latching elements of the receptacle from disengaging from one or more latching elements of the MPO connector module.
9. The method of claim 8 , wherein the spring clip comprises sheet metal.
10. The method of claim 8 , wherein in the unlocking state, at least the distal end of the spring clip is retained within the keying slot of the MPO connector module until a user removes the spring clip from the MPO connector module.
