A terminal module includes a number of conductive terminals. The conductive terminals include a first signal terminal and a second signal terminal. A contact portion of the first signal terminal includes a first contact arm, a second contact arm and a first clamping space. The first contact arm includes a first contact end portion and a first contact arm body portion connected with the first contact end portion. The first contact arm body portion includes a first end connected to the first contact end portion and a second end opposite to the first end. From the first end to the second end, a width of the first contact arm body portion gradually increases. As a result, it is beneficial to improve the contact impedance when it is mated with a mating backplane connector. The present disclosure also discloses a backplane connector having the terminal module.

A stacked I/O connector for use with a high speed, high density transceiver that generates a large amount of heat. The connector may be formed with a web-like housing into which leadframe assemblies are inserted. The web-like housing may have openings in the front, back, top and/or sides, enabling airflow through the connector with little resistance. Sidewall openings may open into a channel between the housing and a wall of cage, enabling air flowing to cool transceivers inserted into the cage to pass through the connector assembly with low resistance and high cooling efficiency. A cage for the connector may have openings selectively positioned such that air flowing through the cage to cool transceivers mated to the I/O connector may pass through the connector with low resistance, enhancing cooling efficiency. Such a connector may be used with OSFP transceivers to meet signal integrity and thermal requirements at 112GBps and beyond.
