Abstract

<P>PROBLEM TO BE SOLVED: To perform a fastening operation with a plier in a coaxial cable caulking ring for making a coaxial connector integrally stick on the tip of a coaxial cable, and to simply perform an operation for removing the coaxial connector from the coaxial cable. <P>SOLUTION: A pair of tool locking projections 22, 24 are arranged on an outer peripheral surface of a caulking ring 30 in order to perform the fastening operation with a plier without using an exclusive tool when sticking the caulking ring on the coaxial cable with a plier by arranging the caulking ring 30 in the vicinity of the tip of the coaxial cable wherein the coaxial connector is inserted and connected. Therefore, a groove section 26 (or a hole or a notch) for assisting cutting of the caulking ring 30 is formed on an outer peripheral surface or an inner peripheral surface of the caulking ring 30 since it is difficult to remove the caulking ring 30 from the coaxial cable for reuse of the coaxial connector when the tool locking projections 22, 24 are simply arranged. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a coaxial cable caulking ring that is disposed around the distal end of a coaxial cable to which a coaxial connector is fitted and connected, and is deformed by an external tightening operation to integrally fix the coaxial connector to the distal end of the coaxial cable.

  Conventionally, a coaxial connector 10 fixed to the tip of a coaxial cable includes, for example, an insulating member 6 around the core wire 4 of the coaxial cable 2 and a braided conductor 8 around the insulating member 6 as shown in FIG. A cylindrical insertion portion 12 that can be inserted between the insertion portion 12, a flange 14 that is provided at one end of the insertion portion 12 for positioning the coaxial cable, and the insertion portion 12 is turned to the opposite side of the coaxial cable side. The nut portion 16 is provided so as to be freely movable and can be screwed into an external conductor such as a plug to be connected.

  When this type of coaxial connector 10 is fixed to the coaxial cable 2, as shown in FIG. 7B, after inserting the insertion portion 12 inside the braided conductor 8 of the coaxial cable 2, A coaxial cable caulking ring 20 (hereinafter, simply referred to as caulking ring 20) is disposed and tightened to secure the coaxial cable 2 and the insertion portion 12 of the coaxial connector 10 together from the outside of the coaxial cable 2. Generally, it is made to do (refer FIG.7 (c)).

Further, if the caulking ring 20 is simply formed in a ring shape, a special tool is required for tightening. Therefore, the caulking ring 20 has an outer peripheral surface as shown in FIGS. 7 (d) and 7 (e). Further, by providing a pair of tool locking protrusions 22 and 24 that are parallel to each other across a surface passing through the central axis of the caulking ring 20, the caulking ring 20 can be tightened with a general pliers or the like.
