Plug connector for transceiver module, receptacle assembly for transceiver module, and transceiver module assembly

Abstract

In a transceiver module, when one end portion of a module board ( 18 ) is inserted and connected to a concave portion ( 16 R) of a plug connector ( 16 ), a projection portion ( 16 PP) formed on the periphery of the concave portion ( 16 R) of the plug connector ( 16 ) is fitted into a notch portion ( 18 PH) as one end surface of the module board ( 18 ) comes into contact with an inner peripheral surface that forms the concave portion ( 16 R).

1 . A receptacle assembly for transceiver module comprising:
 a connector connected to a transceiver module; and   a receptacle cage including   a module accommodating portion including a module slot provided at one end and configured to allow passage of the transceiver module, the module accommodating portion being configured to attachably and detachably accommodate the transceiver module,   a connector accommodating portion communicating with the module accommodating portion and being configured to accommodate the connector, and   a stopper piece provided at the module accommodating portion and configured to guide the transceiver module in a first attitude being inserted into the module accommodating portion, and when the transceiver module in a second attitude inverted from the first attitude is inserted into the module accommodating portion, to restrict an insertion operation of the transceiver module.   
     
     
         2 . A receptacle assembly for transceiver module comprising:
 a connector connected to a transceiver module; and   a receptacle cage including   a module accommodating portion having a module slot provided at one end and configured to allow passage of the transceiver module, the module accommodating portion being configured to attachably and detachably accommodate the transceiver module, and   a connector accommodating portion communicating with the module accommodating portion and being configured to accommodate the connector.   
     
     
         3 . The receptacle assembly for transceiver module according to  claim 2 , wherein the receptacle cage has a pair of projection portions located at positions adjacent to a lock piece to be selectively engaged with a fixing piece of a release lever of the transceiver module, and configured to come into contact with a neighborhood of the fixing piece of the release lever of the inserted transceiver module. 
     
     
         4 . The receptacle assembly for transceiver module according to  claim 2 , wherein
 a connection end of the transceiver module has a plurality of grooves to which a plurality of contact terminals are provided, respectively, and   at least adjacent two of the grooves communicate with each other through a notch portion.   
     
     
         5 . The receptacle assembly for transceiver module according to  claim 2 , wherein
 a slit penetrating a connection end of the transceiver module along a thickness direction of the connection end is formed in each groove, and   a concave portion is formed in a contact terminal at a position corresponding to the slit.
