Socket for optical fiber plug
A socket for a releasable and reproducible assembly with an optical fiber plug. The socket has a main housing and an access shaft for inserting an optical fiber plug with a plug housing. At the inner end of the access shaft an optical fitting surface is arranged that is inverse to an optical fitting surface of the optical fiber plug. The main housing has a knurled ring, at least one movable engagement pin and a locking ring. The closing path of the engagement pin is formed by a guiding groove in the locking ring with at least two sections. The guiding groove has a first azimuthally extending portion and a second axially extending section with a recess at the end region of a transversal groove. A friction-locked snapping in of the engagement pin into the recess at the end region of the transversal groove occurs.
1. A method for a releasable and reproducible assembly of an optical fiber plug with a socket, comprising the steps of:
a. inserting an optical fiber plug into an access shaft formed within a main housing of a socket, wherein the socket includes a locking mechanism that is moveable relative to the main housing and the access shaft and that is operably connected to at least one movable engagement member that extends into the access shaft and is configured to traverse a groove formed in a housing of the inserted fiber plug, the groove defining a closing path;
b. manipulating the locking mechanism to cause traversal of the engagement member within the groove along a first section of the closing path;
c. manipulating the locking mechanism to cause traversal of the engagement member within the groove along a second section of the closing path to an end position that results in a friction-locked connection of the optical fiber plug within the access shaft.
2. The method of claim 1 , wherein the movement in the first section of the closing path of the engagement member is coupled to a first rotational movement of the locking mechanism and is coupled in the second section of the closing path of the engagement member with a second rotational movement of the locking mechanism.
3. The method of claim 1 , wherein first and second rotational movement are coupled to a total rotational movement of the locking mechanism.
4. The method of claim 1 , wherein first and second rotational movement are separated by a stop at the end of the first rotational movement.
5. The method of claim 1 , wherein a transition to the second rotational movement at the end of the first rotational movement comprises a pulling movement of the locking mechanism in an axial direction.
6. The method of claim 1 , wherein the friction-locked connection between the access shaft and the optical fiber plug is achieved by applying an axial pressing force.
7. The method of claim 1 , wherein the manipulating of the locking mechanism is an axially acting moment of force.
8. The method of claim 1 , wherein moving the engagement member in the second section of the closing path is done in parallel to contacting electrical contact pins of the socket with contact surfaces of the optical fiber plug.
9. The method of claim 1 , wherein during at least a portion of the traversal of the engagement member in the closing path occurs without frictional engagement between the engagement member and the groove.
