[Problem that the idea aims to solve]

However, in the conventional coaxial multi-cable connector C, the coaxial ribbon cable Each coaxial cable 22 constituting the cable 21 is connected to the coaxial line at the connector part.

There is a problem that

0004 Also, unlike a coaxial line, the center conductor 23 is not covered by the outer conductor 24. Therefore, a phenomenon in which signals are transferred to adjacent lines, a so-called crosstalk phenomenon, occurs. There is a problem in that it causes noise.

【Example】 Hereinafter, an embodiment of this invention will be described based on the drawings. Figure 1 shows the coaxial multi-layer structure of this invention. FIG. 2 is a cross-sectional view showing the cable connector, and FIG. 2 is a perspective view thereof. Shown in these figures As shown, the coaxial multi-cable connector A of this embodiment is a coaxial multi-cable connector. Each coaxial cable 2, 2... constituting the cable (coaxial ribbon cable in this embodiment) 1 It is formed by housing the coaxial connector section 5 connected to each of the case 8 in the case 8. There is. The coaxial connector section 5 has an inner conductor 10 inserted inside a cylindrical outer conductor 9. , which is insulated and held within the outer conductor 9 by a support member 11 made of insulating resin. The end 9a of the outer conductor 9 of this coaxial connector part 5 is connected to the outer part of the coaxial cable 2. The external drain wire 6 is electrically connected to a conductor (not shown) by pressure contact. There is. Furthermore, the end of the inner conductor 10 of the coaxial connector section 5 is covered with an insulator 12. The central conductor 13 is connected. In this way, the end of each coaxial cable 2 The coaxial connector part 5 connected to the end is housed in a case 8, and the coaxial connector part 5 connected to the end is housed in a case 8. The surface has a hole 8a for connecting the coaxial connector 5 to the mating connector B. It is formed.

[0009] On the other hand, the mating connector (for example, Board mounting connector) B is connected to each of the above coaxial connectors 5 inside the case 17. The same number of connector parts 14 as the above-mentioned coaxial connectors 5 are stored. The conductor portion 14 is formed from a cylindrical outer conductor 15 and an inner conductor 16 that is insulated and held inside the cylindrical outer conductor 15. has been done. The outer conductor 15 and the inner conductor 16 are connected to the substrate 19. The second terminal 18 is pulled out.
