Miniature adapter for mpo plug

An adapter for MPO plug formed by an adapter main body, the adapter main body comprising:

• a plug insertion and removal opening portion provided for interconnecting a plug main body and communicating back and forth;
• and
• the plug main body comprising as primary members:
• a spring push which is provided in a rear end portion of the plug main body;
• a coupling which is mounted to the plug main body so as to be slidable back and forth in a forward side of the spring push;
• and
• a spring which elastically biases the coupling to a forward side of the plug main body,
• wherein the adapter main body is formed into a tubular shape by upper and lower wall portions which are approximately flush with the upper and lower wall portions of the coupling, and right and left wall portions which are approximately flush with the right and left wall portions of the coupling, and is provided in both front and rear ends of the right and left wall portions of the adapter main body with elastic locking portions which are provided so as to face to the plug insertion and removal opening portion side, and
• wherein the locking of the adapter main body in relation to the elastic locking portion is retained by a forward movement of the coupling in dependence on an elastic biasing force of the spring to the forward side of the plug main body, and the locking of the adapter main body in relation to the elastic locking portion is disengaged by a rearward movement of the spring against the elastic biasing force to the forward side of the plug main body, thereby capable of getting out.
