Description

  The present invention provides a coaxial cable connector that can easily hold the coaxial cable and the components constituting the connector in order to facilitate solder joining between the coaxial cable and the components constituting the connector when the connector is attached to the coaxial cable. The present invention relates to a soldering jig and a soldering method using the coaxial cable connector soldering jig.

  2. Description of the Related Art Conventionally, for high-frequency communication, an operation for attaching a connector to the end of a coaxial cable has been performed in order to connect the coaxial cable to a power feeding portion provided on a distribution board of an antenna and a power control room. 3 and 4 are diagrams showing an example of the configuration of this type of coaxial cable and a connector attached to the terminal.

  The coaxial cable shown in FIG. 3 includes a center conductor 13, an insulating coating 12 formed outside the central conductor, an outer conductor 14 formed outside the insulating coating, and an external formed outside the outer conductor. It is composed of a coating 15. Further, the connector shown in FIG. 4 is inserted with a coaxial cable that is removed stepwise so that the outer conductor is removed and the outer conductor and the insulating coating are left to have a predetermined length, leaving the central conductor. A center pin 16 to be joined to the center conductor by solder, a guide component 19 to be inserted and fitted to the end face of the coaxial cable from which the outer covering has been removed, and an insulator 18 to be inserted into the center pin 16 A cap nut 17 is provided for holding and fixing the center pin 16 and the insulator 18 together with the guide component 19.

  In order to further stabilize the impedance of the coaxial cable, the coaxial cable has the outer conductor 15 removed, and the central conductor 13 remains, so that the outer sheath 15, the outer conductor 14 and the insulating sheath 12 have the same cutting position. A method of excision is adopted. The center conductor of the coaxial cable thus obtained is inserted into the center conductor insertion groove 21 of the center pin and joined while melting solder from the solder hole 20 of the center pin. Install in the specified position.

  Thereafter, the end face of the insulating coating of the coaxial cable and the end face of the guide part of the connector are inserted at specified positions, for example, the end faces of both are flat, and the center pin 16 is fixed with a fixing tool such as a vise. It fixes (for example, refer patent document 1). Finally, from the opposite side of the end face of the coaxial cable, the solder is poured into the gap between the guide part 19 and the outer conductor 14, and the guide part and the outer conductor are joined together. Install so that the end face is in place.

  Then, the insulator 18 which is a component part of the connector is inserted into the center pin 16 described above. Further, it is inserted into the cap nut 17, the threaded portion of the guide part and the threaded portion of the cap nut are rotated, and tightened with a torque spanner to complete the coaxial cable.

  However, as described above, the center pin is pinched by using a fixing tool such as a vise when the coaxial cable and the guide part are attached, so that the center pin is damaged.

  Also, solder with a fixed tool such as a vise so that the end face of the coaxial cable and the end face of the guide part are flat, but it is unstable and the mounting position is likely to vary, so check that it is flat. However, it takes time to solder.

  As a method of soldering the center conductor and the center pin of the coaxial cable without using a fixing tool such as a vise, the center connector (corresponding to the center pin) of the coaxial connector to be soldered is the core wire (corresponding to the center conductor) A coaxial cable connector mounting jig having a fixing groove for storing and fixing the tip end portion of the coaxial cable covered with the cable, and a soldering method using the coaxial cable connector mounting jig. (Patent Document 2). As another method, a connector assembly jig having a clamp body for fixing a coaxial cable, an inner conductor of the coaxial cable, and a holder into which a supporter for soldering a contact (corresponding to a center pin) is inserted, and A soldering method used in the connector assembly jig is disclosed (Patent Document 3).

When the coaxial cable and the antenna were connected using the connector to which the coaxial cable thus obtained was attached, both impedance matching and stability were evaluated. As a result, the impedance matching between the coaxial cable and the antenna showed almost the same characteristics as those obtained in the first embodiment, but the impedance stability was found to be slightly inferior. However, it was confirmed that the impedance matching and stability were superior compared to the case where only the center pin of the connector and the center conductor of the coaxial cable were soldered.

  As described above, according to the present invention, the position of the end face of the insulation coating of the coaxial cable and the position of the outer surface of the guide part can be freely set with high accuracy by the shape of the hole formed in the second inner wall portion. Therefore, the electrical characteristics when the coaxial cable and the antenna are connected can be stabilized as compared with the case where a conventional soldering jig is used.
