摘要:
A high frequency electrical connector (1) comprises a socket (2) and a plug (3). The plug is insertable into the socket in a first direction (1D), the socket and plug each having multiple electrical contacts (25, 26, 35) which are arranged to electrically interconnect the plug and socket. The socket has a base (4) for fixedly mounting a fixed end (42, 45, 46) of the contacts. The contacts have contact areas (55) arranged for electrically interconnecting to corresponding plug contacts, the contact areas being aligned so as to be parallel in a first dimension (1M) with the first direction (1D), and having a resiling portion (66) in-between the contact areas and the fixed ends (46), the socket contacts are formed in several different shapes (IS, 2S, 3S, 4S), wherein each shape has an at least partly arcuate contact area (81 to 88) and wherein a free end (76) of each contact is enclosed by the base (4).

An electrical plug (1) for high frequency data transmission comprises at least a termination block (5) and a wire management element (7) arranged for connection to a cable (10). The cable has a plurality of wires (11) each with a conductor (21), and the wire management element is arranged so that it receives and guides the wires into a series of open ended channels (63) within the termination block. The termination block is arranged to receive a plurality of contacts (6) and is arranged to retain the contacts in a first position in the block and a second position in the block. Each contact is moveable from the first position (see 20F Figure 20A ) to the second position (see 20J in Figure 16 and Figure 20B ), and arranged so that in the first position the wires may be inserted through the channels, and in the second position each contact is held by the termination block in electrical contact with a conductor. The plug further comprises a housing (2) arranged to receive the wire management element and the termination block when the contacts are in the second position.
摘要:
A high frequency cable (1) for the 0.5 MHz to 1000 MHz range including at least one twisted pair (4, 5, 6, or 7) of conductors (8, 9) forming at least a part of a core (3), the core being covered by a sheathing (2), and the sheathing have a cross-sectional external shape (15) in the form of a reuleaux polygon (16), which results in an increased separation between cables (1') in a bundle.
摘要:
An apparatus for installing, by the blown fibre technique, at least one optical fibre or optical fibre unit ( 5 ) into a tube or tubular passageway ( 6 ), comprising a length of optical fibre/optical fibre unit on a reel or cartridge ( 8 ) which is contained within a pressure vessel ( 2 ), the length of optical fibre/optical fibre unit being preterminated at its inside tail by a connector ( 32 ).
摘要:
A multi-tube terminal connector for connecting tubes into which optical fibres are to be installed by the blown fibre technique, comprising a first part (4a) arranged to receive and fit onto a cable (1) of closely packed tubes, and a spreader (5) provided with guideways to splay the tubes received by the first part from their initially closely packed state to a spaced relationship where the 10 spacing is greater than the spacing at the initially closely packed state, the arrangement being such that provision (22) is made so as to connect the connector to at least one further element.

摘要:
A coupling for conduit tubes (16, 16′) for carrying optical fibres or optical fibre units, comprising a body which has two entries (18, 18′) , both entries having associated therewith means (20, 20′) to secure the body to conduit tubes inserted into the entries, the body being further provided with a space or chamber (42) between the entries through which one or more optical fibres or optical fibre units may pass, the body having a third entry (34) arranged to enable insertion of sealing material into the space, and means, such as deformable seals (26, 26′), to maintain the sealing material within the space .
