To make two sets of transmitting and amplifying units to be interchangeable and, in addition, to be plugged in an enclosure structure for electronic equipment equipped with a natural air-cooling function.

In the enclosure structure for electronic equipment, two units 10 and 11 respectively having radiators 19 are plugged in the enclosure 1 of the equipment so that the radiators 19 may come on the outside. In the structure, fixed connector units constituted by attaching required connectors to the units 10 and 11 are provided and sliding connector units to which connecters inserted into the connectors attached to the units 10 and 11 are provided obliquely movably with respect to the plugging-in direction, so that the sliding connector units may be engaged with the fixed connector units at prescribed positions during the course of plugging-in operation and the connectors may be inserted into the connectors during the course of the remaining plugging-in operation.
