Leakage of electromagnetic noise from a wiring substrate is suppressed. A wiring substrate (1) includes a multilayered wiring layer, a structure (8) of a conductor, and an electromagnetic wave absorber (5). An electronic component (2) which is an example of an electromagnetic noise generation source is mounted on the wiring substrate (1). The electronic component (2) has a high-frequency circuit. The structure (8) is formed using the multilayered wiring layer, and is arranged so as to enclose the electronic component (2) in plan view with an opening (4) in the enclosure. The electromagnetic wave absorber (5) is arranged so as to cover the opening (4).

In order to drive connectors relatively to mating connectors in a housing for connection and disconnection of the connectors with the mating connectors, the connectors have projections thereon which projects outside of the housing when received in the housing, and a slider is slidably mounted on the housing and having a groove with a cam portion for receiving the projection. When the slider is pulled or pushed, the projection is driven by the cam portion of the groove to drive the connectors. Partitions are mounted in the housing to partition an inner space of the housing into a plurality of rooms for accommodating the connectors so as to separate between adjacent connectors by the partition. Each of the partition has engaging projections engaged with engaging holes formed in the housing wall. One of the engaging holes is registry with the groove of the slider so that the corresponding one of the engaging projection is also received in the groove at the projecting end through the engaging hole. The slider is also provided with a slot for receiving the other engaging projection projecting through the other corresponding engaging hole. Thus, the slider, if it is made with small size, has a desired mechanical strength and can be smoothly moved.

There is provided an insertion and withdrawal connector apparatus in which a plurality of connectors can move only in a range of capable of engaging and separating with and from a plurality of mating connectors within a connector receiving body. A connector receiving body (1) has a pair of parallel frames (3), a pair of frame blocks (4) positioned at both end portions, and a plurality of partition members (5). One connector (10) and one mating connector are received in each of a plurality of space portions, that is, receiving chambers partitioned by a pair of frames, a pair of frame blocks, and a plurality of partition members. Each of the partition members has a pair of lances (5f, 5g) having a spring characteristic and each of the connectors has a pair of interlocking groove portions (10g) on both side surfaces. The lance (5f) interlocks with the interlocking groove portion on one of the side surfaces in the connector, and the lance (5g) interlocks with the interlocking groove portion on the other of the side surfaces in the connector. Each of the connectors has a convex portion (10d) at an upper end portion on one of the side surfaces and at a lower end portion on the other of the side surfaces, and each of the convex portions interlocks with each of the partition members.

A multi connector device comprising a plurality of connector pairs of first connectors and second connectors mating therewith, and a multi-connector support housing for accommodating the connector pairs. The multi-connector support housing comprises a support housing defining a plurality of connector accommodating chambers therein which are arranged in order and accommodate the connector pairs therein, respectively. A plurality of pairs of guide engaging portions are formed on the support housing at the connector accommodating chambers and engaging the connector pairs accommodated in the chambers and guiding the connector pairs to move in connecting and disconnecting directions in the chambers, respectively. A slider as a connector driving member is removably assembled onto the support housing to drive the connector pairs in a selected one of the connecting and disconnecting directions. In a specific structure, the support housing comprises two housing members which are removably jointed together to form the support housing and accommodate the first connectors and the second connectors, respectively.
摘要:
A polyimide multilayer wiring board is constructed by using a plurality of laminated blocks each of which has a plurality of wiring layers and interlaminar insulating layers of polyimide. On a base block having a substrate, the other blocks are laid on top of another, bonded to each other with a polyimide used in each block or another adhesive and electrically connected to each other by using, for example, metal bumps formed on each block. Each of the blocks except the base block is formed on a temporary substrate, and the temporary substrate is removed after bonding each block to the base block or precedingly bonded blocks. This multilayer wiring board can be produced in a shortened time with increased yield.
