  Regarding the connection structure between the coaxial cable and the coaxial connector, the following structure has been proposed. That is, first, the braid is exposed at the end of the coaxial cable, and the exposed braid is loosened. In the gap between the loosened braid and the inner metal tape conductor (or insulator), the connecting conductor portion of the coaxial connector The work of inserting is performed. Next, an operation of caulking a metal sleeve that is a separate body from the coaxial cable and the coaxial connector at the position of the exposed braid is performed. By caulking the metal sleeve, the coaxial cable and the coaxial connector are electrically and mechanically connected (see, for example, Patent Document 1).

  Before starting the description, in the present specification, a structure in which a coaxial connector or a grounding terminal fitting is electrically connected to a coaxial cable terminal and mechanically fixed is defined as a coaxial cable terminal processing structure. In the present specification, although not particularly limited, a case where a coaxial connector is provided in a terminal will be described.

  In FIG. 1, reference numeral 1 indicates a coaxial cable, and reference numeral 2 indicates a coaxial connector. The coaxial cable 1 has an annular protruding braided portion 3 that is the gist of the present invention. The coaxial connector 2 includes an inner terminal 4 and a shield terminal (coaxial cable shield terminal) 5. The shield terminal 5 has a braided connection fixing portion 6 which is the gist of the present invention. Hereinafter, each configuration will be described with reference to FIGS. 1 to 9.

  The coaxial cable 1 includes a core wire 7 as a central conductor, an insulator 8 as a dielectric, a metal tape conductor (not shown) and a braid 9 as external conductors, and an insulating sheath 10 as an outer sheath.

The core wire 7 to the insulating sheath 10 are known ones, and detailed description thereof is omitted here.

  The annular projecting braid 3 is formed at the end of the coaxial cable 1. Specifically, it is arranged and formed at a predetermined position from the end face of the coaxial cable 1. The annular projecting braided portion 3 is formed by processing the braid 9 and is formed in the shape shown in the figure so as to project annularly to the outside of the insulating sheath 10.

  Here, the formation of the annular protruding braided portion 3 will be described. Assume that the terminal of the coaxial cable 1 is in a state as shown in FIG. First, as shown in FIG. 3, the middle of the insulating sheath 10 is peeled, and one insulating sheath 10a and the other insulating sheath 10b are formed on both sides of the peeled portion. One insulating sheath 10 a is located on the end face side of the coaxial cable 1. The braid 9 is exposed from the peeled portion. Next, as shown in FIG. 4, one insulating sheath 10a is drawn toward the other insulating sheath 10b. At this time, the braid 9 in an exposed state protrudes annularly from between the end portions of the one insulating sheath 10a and the other insulating sheath 10b along with the drawing. The annular protruding braided portion 3 is formed by such a procedure.

  Since the braid 9 is covered with the other insulating sheath 10b in particular, it has a structure in which the annular protruding braid 3 itself does not move. As will be described later, the shield terminal 5 is electrically and mechanically connected to such an annular protruding braided portion 3 via a braided connection fixing portion 6.

It has a fixed terminal processing structure. Therefore, as can be seen from the above description, the present invention can make work related to terminal processing easier than before. That is, according to the present invention, by forming the annular projecting braided portion 3, the conventional braid unraveling work can be eliminated. In addition, the present invention can eliminate the work of inserting a part of the conventional shield terminal inside the braid 9. Therefore, the present invention can facilitate the work related to terminal processing (the shield terminal 5 of the present invention has the same effect).

  In addition, in the present invention, a metal sleeve that has been conventionally required can be eliminated. Therefore, the terminal processing of the coaxial cable 1 can be performed with a smaller number of parts than before. Moreover, in this invention, it can be set as the structure which does not deform | transform the insulator 8 of the coaxial cable 1, and the cross-sectional outline of the said external conductor. Therefore, the high frequency characteristics can be maintained better than before.
