An enclosure for an extension cord connector having a first container member forming a first receptacle and a second container member forming a second receptacle. The adjoining edges of the first and second receptacle form a continuous edge with reciprocal tongue and groove coupling, the first container member forming a mirror image of the second container member. In operation, a connector of a power cord and extension cord are placed in the first receptacle formed by said first container member and the extension cord placed in the second receptacle secured together by coupling the tongue shape continuous edge of the second container member to the groove shape continuous edge of the first container member.

An explosion-proof fitting for antennas suitable for connecting an antenna in hazardous areas is provided. The explosion-proof fitting has a housing defining a cavity between a first end and a second end, an antenna attachment at the first end and a radio attachment at said second end, and a central assembly accommodated in the cavity. The central assembly has a capacitive blocking circuit connected to the antenna attachment and the radio attachment, and a shielding casing running about the capacitive blocking circuit and remaining at least partially spaced apart for capacitive blocking circuit and from the housing. A sealing compound is arranged between the shielding casing and the housing. A central assembly for an explosion-proof fitting, and an explosion-proof box including the explosion-proof fitting are also provided.

The invention relates to a plug connector designed to transmit electric power via at least two contact parts which are mounted in a contact support and to cool same while transmitting electric power, each contact part comprising a connection element which is connected to an electric line. A supply line for supplying a cooling fluid is provided in a common cooling chamber delimited by a cooling housing, and a respective tube is arranged about each line in order to convey the cooling fluid away from the cooling chamber, wherein each connection element is at least partly arranged in the cooling housing and additionally comprises a tube receiving area for receiving the respective tube, in which the corresponding electric line is received such that a line cooling region is formed for the electric line, and the connection element comprises at least one opening for fluidically coupling at least the cooling chamber. The cooling housing has at least one inlet for the cooling fluid, said inlet being connected to the supply line for the cooling fluid, and the cooling housing comprises a flow direction control means which is shaped and/or designed such that a cooling fluid entering through the inlet flows around the respective connection element in a rotating manner at least in some sections at least in the cooling chamber.
