Protective cage assembly, receptacle connector and connector assembly with improved light guide pipe

A receptacle connector, comprising:

• a protective cage assembly comprising:
• a cage comprising an end face and an accommodating space;
• and
• a light guide pipe comprising an input surface, an output surface and a main body portion extending between the input surface and the output surface, the main body portion comprising a first portion, a second portion and a third portion connected between the first portion and the second portion, the first portion being located inside the cage, the second portion being located outside the cage, and the third portion passing through a side wall of the cage;
• and
• wherein the first portion is located adjacent to an inner surface of the side wall, and extends along the inner surface of the side wall at least to the end face of the cage;
• and
• a connector located in the accommodating space and away from the end face of the cage;
• wherein the second portion is located adjacent to an outer surface of the side wall, and the second portion extends along the outer surface of the side wall;
• the first portion extends along a first direction;
• the second portion comprises a horizontal section, a vertical section and a curved section connected between the horizontal section and the vertical section;
• the horizontal section extends along the first direction;
• the vertical section extends along a second direction;
• and the second direction is perpendicular to the first direction.

A connector assembly, comprising:

• a receptacle connector comprising a protective cage assembly and a connector, the protective cage assembly comprising:
• a cage;
• and
• a light guide pipe comprising an input surface, an output surface and a main body portion extending between the input surface and the output surface, the main body portion comprising a first portion and a second portion, the first portion being located inside the cage, the second portion being located outside the cage;
• wherein the first portion is located adjacent to an inner wall of the cage, and extends along the inner wall of the cage at least to a front face of the cage;
• the connector is located in a rear of the cage of the protective cage assembly and away from the front face of the cage;
• and
• a plug connector at least partially inserted into the cage of the protective cage assembly of the receptacle connector so as to be electrically connected with the connector;
• wherein the second portion comprises a first section, a second section and a curved section;
• the first section extends along a first direction;
• the second section extends along a second direction;
• the curved section extends between the first section and the second section;
• and the second direction is perpendicular to the first direction.
