  • Publication number: 20040266230
    Abstract: There is provided a transmission device (A) arranged in an electronic apparatus (1) having a circuit board (3) for input and/or output and a conductive body (9). The transmission device (A) comprises a relay cable (7) having first and second ends (7a, 7b). The first end (7a) of the relay cable (7) is connected to the circuit board (3). A receptacle type connector (11) attached to a reverse surface (9a) of the body (9) is provided at the second end (7b) of the relay cable. In order to prevent generation of radiation noises from the relay cable (7), a metal shell in the receptacle type connector (11) is grounded to the body (9).

  • Patent number: 6599151
    Abstract: A receptacle type intermediate connector 1 has an insulated body 2 with a forward end opening 3 for reception of a mating connector, and contacts 4 fixed in the body and each having at its end a finger 5 for engaging a foreign contact held in the mating connector. Each contact has at its other end a leg 6 adjoined to one electric wire in a signal transmission cable. A metallic shield composed of covers 7-9 encloses the body 2, the contact legs 6 and wires' bare ends, and has a collar portion 23 gripping a shielding layer of the cable. The connector has an insulated housing 10 and 11 covering the metallic shield disposed in the housing. The forward region of first metallic cover 7 of the shield is formed as a squarely-cylindrical portion 15. This portion protrudes ahead the end opening 3, 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.

  • Patent number: 6506075
    Abstract: An angle type plug connector 1 has an insulated body 2 for insertion into a mating connector, and contacts 3 fixed in the insulated body and each having at its one end a finger 9 for contact with a foreign contact held in the mating connector, each contact having at its other end a leg 10 adjoined to one electric wire 36 in a signal transmission cable 35. The connector also has an angle type shield 32 consisting of a pair of first and second metallic covers, the first cover 4 enclosing outer portions of the insulated body 2, and the second cover 5 enclosing the contacts' legs 10 and the wires' bare end portions, so that the second cover extends at a right angle relative to the first cover.
