Definitions

  • Patent Document 1 As a coaxial cable connection structure, a structure in which a slit is provided on the upper surface of a printed circuit board and a connection pattern with an external conductor is formed on both sides of the slit is known (see Patent Document 1). According to the technique disclosed in Patent Document 1, an outer conductor of a coaxial cable can be placed in a slit provided in a printed circuit board, and the outer conductor can be connected to connection patterns on both sides of the slit. Only the coaxial cable mounting height can be lowered.
  • the cable connection structure includes: a cable having a core wire exposed on a front end surface; and a substrate on which an electrode for connecting the cable is formed on a predetermined connection side surface, and the front end of the cable The surface and the connection side surface of the substrate are connected by a conductive material.
  • FIG. 1 is a partial cross-sectional view illustrating the cable connection structure of the first embodiment.
  • FIG. 2 is a perspective view illustrating the configuration of the substrate according to the first embodiment.
  • FIG. 3 is a partial cross-sectional view illustrating the cable connection structure of the second embodiment.
  • FIG. 4 is a partial cross-sectional view illustrating the cable connection structure of the third embodiment.
  • FIG. 5 is a partial cross-sectional view illustrating the cable connection structure of the fourth embodiment.
  • 6 is a cross-sectional view taken along line AA in FIG.
  • FIG. 7 is a diagram illustrating the front end surfaces of a plurality of coaxial cables connected to the substrate by the cable connection structure of the fourth embodiment.
  • FIG. 8 is a plan view showing a connection side surface of a substrate to which a plurality of coaxial cables are connected.
  • the front end surface 11 of the coaxial cable 1 and the connection side surface 31 of the substrate 3 are electrically and physically connected by an anisotropic conductive material (not shown) such as ACF or ACP. That is, when connecting them, first, the tip end face 11 and the connection side face 31 are disposed opposite to each other with an anisotropic conductive material sandwiched therebetween, and the conductive film 21 and the center conductor connection electrode 311 are opposed to each other. The conductive film 23 and the external conductor connection electrode 313 are opposed to each other.
  • an anisotropic conductive material is thermocompression bonded to connect the conductive film 21c and the central conductor connection electrode 311c, and connect the conductive film 23c and the external conductor connection electrode 313c to connect the tip surface 11c and the connection side surface 31b. Join.
  • the coaxial cable 1 d has the same configuration as that of the first embodiment, and the outer conductor 14 that is a shield wire is formed on the outer periphery of the center conductor 12 that is a core wire via an inner insulator 13.
  • the outer conductor 15 is provided on the outer periphery of the outer conductor 14.
  • seven coaxial cables 1d are arranged in parallel and connected to the substrate 3d.
  • the conductive film 21 is provided on the exposed portion of the center conductor 12 on the tip surface 11 of each coaxial cable 1d, and the exposed portion (tip) of the center conductor 12 is flattened.

  • each outer conductor connection electrode 313 d is formed such that the length of one side thereof is smaller than the radial width between the outer periphery of the center conductor 12 and the outer periphery of the outer conductor 14. As a result, the external conductor connection electrode 313d does not come into contact with the center conductor 12 to cause a short circuit of the wiring.
  • an insulating layer 4 that covers the wiring patterns 351d and 353d is provided on the connection side surface 31d of the substrate 3d at a portion above the position where the central conductor connection electrode 311d and the external conductor connection electrode 313d are formed. As shown in FIG. 5, the insulating layer 4 is interposed between the wiring patterns 351d and 353d and the end face 11 of the coaxial cable 1d when the plurality of coaxial cables 1d are connected to the substrate 3d. Therefore, it is possible to prevent the wiring patterns 351d and 353d from coming into contact with the outer conductor 14 of each coaxial cable 1d and the like to cause a short circuit.
  • each coaxial cable 1d and the connection side surface 31d of the substrate 3d are electrically and physically connected by an anisotropic conductive material (not shown) such as ACF, as in the first embodiment. That is, when connecting them, first, the tip end surface 11 and the connection side surface 31d are arranged to face each other with an anisotropic conductive material sandwiched therebetween.
