There is provided an electric connector that is interposed between an in-vehicle wire cable 11a and a train information transmission/reception apparatus. The in-vehicle wire cable 11a includes a plurality of signal lines 41 that transmit train information and an electrically-conductive shielded layer 45 surrounding the signal lines 41. One end of a ground line 32 is connected to the shielded layer 45. A casing ground is provided on a casing of the train information transmission/reception apparatus and a plurality of plug pins electrically connected to the signal lines 41 are provided on the casing of the train information transmission/reception apparatus. The other end of the ground line 32 is connected to an electrically-conductive connector case 12a, which is a casing of the electric connector, and the connector case 12a is grounded via the casing of the train information transmission/reception apparatus when the signal lines 41 and the plug pins are electrically connected to each other.

[Problem] The invention provides a shield case with a reduced dimension in a first direction in three-dimensional state and with a larger space in the first direction between adjacent holding plates in planar development state. [solution] A first shell 400 of a shield case S includes a first base 410a and a second base 420a arranged side-by-side, and a center plate 430a, a first inner plate 440a, a second inner plate 450a, a first holding plate 460a, and a second holding plate 470a. The center plate 430a is arranged on the Z-direction side relative to the first base 410a and the second base 420a. The first inner plate extends from a first end 411a of the first base 410a to a first end 431a of the center plate 430a. The second inner plate 450a extends from a first end 421a of the second base 420a to a second end 432a of the center plate 430a. The first holding plate 460a is integral and contiguous with a second end 412a of the first base 410a. The second holding plate 470a is integral and contiguous with a second end 422a of the second base 420a.

With the contact connecting of preferably a number of shielded conductor pairs (4) to a board (2) in particular of a plug (36) for high-speed data connections, the board (2) is formed of multiple layers and comprises a conductor path tier (18) and a ground tier (26). A ground contact zone (28) of the ground tier (26) projects, in a tongue-like manner, towards the connected conductor pairs (4). In the region of the ground contact zone (28), the individual conductor pairs (4) are pressed in contact against the corresponding pair shielding (10) thereof. To this end, in particular a clamping element (32) is provided that is also used to achieve the shield contacting.

An intermediate member that enables enhancement of ease of fabrication of a wire harness and a wire harness including such an intermediate member are provided. A wire harness is divided into an intermediate member placed in an intermediate portion of the wire harness and two terminal members placed at respective terminals of the wire harness and to be connected to equipment. After being separately fabricated, the intermediate member and the two terminal members are connected together, whereupon fabrication of the wire harness is completed. The intermediate member includes one or a plurality of intermediate conducting paths, intermediate routing path retaining means retaining a cable routing path geometry of the intermediate conducting paths; intermediate shield means covering and shielding the intermediate conducting paths; and intermediate protection means covering and protecting the intermediate conducting paths.

In a shield wire (21), a sheet shaped metal foil shield member (23) is provided so as to envelop an inner wire part (22) having a plurality of conductors (25) and insulators (26). In the shield wire (23), the inner wire part (22) is enveloped by the metal foil shield member (23) so that the inner wire part (22) is held and an end part of the metal foil shield member (23) is avoided from collapsing or the end is avoided from bounding.

A pair manager for use in securing a twin-axial cable to a printed circuit board is described. The pair manager comprises a generally block-shaped portion containing a pair of channels. The channels extend from the front face to the rear face of the block-shaped portion. An integral flange and a pair of integral fingers extend perpendicularly from the front face of the block-shaped portion. The flange extends generally from the center of the front face and the fingers extend from opposite edges of the front face. The fingers and flange function as a partial shield cavity around each pair of conductors. This design helps to maintain better impedance matching when connecting twin-axial cables to a printed circuit board.
