There is provided a transmission device (A) arranged in an electronic apparatus () having a circuit board () for input and/or output and a conductive body (). The transmission device (A) comprises a relay cable () having first and second ends (). The first end () of the relay cable () is connected to the circuit board (). A receptacle type connector () attached to a reverse surface () of the body () is provided at the second end () of the relay cable. In order to prevent generation of radiation noises from the relay cable (), a metal shell in the receptacle type connector () is grounded to the body ().

Transmission apparatus

A receptacle type intermediate connector has an insulated body with a forward end opening for reception of a mating connector, and contacts fixed in the body and each having at its end a finger for engaging a foreign contact held in the mating connector. Each contact has at its other end a leg adjoined to one electric wire in a signal transmission cable. A metallic shield composed of covers encloses the body the contact legs and wires' bare ends, and has a collar portion gripping a shielding layer of the cable. The connector has an insulated housing and covering the metallic shield disposed in the housing. The forward region of first metallic cover of the shield is formed as a squarely-cylindrical portion This portion protrudes ahead the end opening so that the connector will meet requirements prescribed in the IEEE standards for high-frequency transmission apparatuses, and the end opening for the mating connector has an improved shielding property.

Receptacle type intermediate connector

An angle type plug connector has an insulated body for insertion into a mating connector, and contacts fixed in the insulated body and each having at its one end a finger for contact with a foreign contact held in the mating connector, each contact having at its other end a leg adjoined to one electric wire in a signal transmission cable The connector also has an angle type shield consisting of a pair of first and second metallic covers, the first cover enclosing outer portions of the insulated body and the second cover enclosing the contacts' legs and the wires' bare end portions, so that the second cover extends at a right angle relative to the first cover. An insulated housing encloses the shield such that the insulated body and the cable protrude from the housing and at a right angle to each other, and the housing is split up into a first and second halves and so that these halves extend along a plane that includes the axis of the insulated body and the central line of the cable, the split halves having faces fitted one on another. Retention grooves formed in these faces secure in them guard lugs of the insulated body, and each half and has three side walls around the shield and three interlocking portions formed in and along the side walls, so that a narrower space will suffice in putting the connector in and out of the mating connector so as to increase freedom of handling the cables and match it to various surroundings, rendering it more resistant to a distorting or withdrawing stress imparted to the cable.
