  A coaxial cable used for high-frequency signal transmission such as an antenna wire is generally a core wire as a central conductor, an insulator as a dielectric covering the outer periphery of the core wire, and a shield conductor as an outer conductor covering the outer periphery of the dielectric And a sheath (also referred to as an outer skin) covering the outer periphery of the shield conductor in order from the center toward the outside.

  A coaxial connector is attached to the terminal portion of the coaxial cable having such a configuration in order to connect to a counterpart device or a coaxial cable. The coaxial connector is an electrical conductor such as an electromagnetic wave or static electricity by connecting the inner conductor terminal (inner terminal) for connecting the core wire to the center conductor of the counterpart coaxial connector and the shield conductor as the outer conductor to the counterpart coaxial connector. And a shield terminal as an outer conductor terminal adapted to block noise.

  When connecting a coaxial connector to the end portion of a coaxial cable, first, in order from the distal end side, the sheath, shield conductor, and insulator are removed from the cable end portion to expose the core wire, and the sheath and shield. An insulator exposed portion where the conductor is removed to expose the insulator and a shield conductor exposed portion where the sheath is removed to expose the shield conductor are formed.

  Next, the core wire crimping portion of the inner conductor terminal of the coaxial connector is crimped to the core wire exposed portion. Up to this point, the installation of the inner conductor terminal is completed, and then the process proceeds to the installation of the shield terminal.

  By the way, when the shield conductor of the coaxial cable is composed of a braided wire, the braided wire acts as a cushion even if it is strongly crimped to the shield conductor exposed portion so as to overlap the wire barrel, and the lower side of the braided wire The insulator will not be deformed. However, when the shield conductor is made of an aluminum foil, the aluminum foil does not work as a braided wire as a cushion. For this reason, when crimping strongly so that it may overlap, a crimping force will be strongly transmitted to the lower insulator of aluminum foil, and an insulator may change. If the insulator is deformed, the impedance may be lowered, which is not preferable. In addition, if the pressure is weakly bonded to avoid the deformation of the insulator, the connection performance between the shield conductor and the shield terminal may be deteriorated.

  The present invention has been made in view of the above-described circumstances, and the purpose thereof is a shield terminal capable of exhibiting high connection performance even when the shield conductor is connected to a coaxial cable made of aluminum foil, and It is to provide a connection structure for shield terminals.

In order to achieve the above-described object, the shield terminal according to the present invention is characterized by the following (1).
(1) A coaxial connected to a terminal portion of a coaxial cable including a core wire, an insulator covering the outer periphery of the core wire, a shield conductor covering the outer periphery of the insulator, and a sheath covering the outer periphery of the shield conductor A shield terminal for cables,
The shield terminal is divided into a first terminal located on the rear side and a second terminal located on the front side,
The first terminal is provided with a sheath crimping portion that is crimped to the sheath of the end portion of the coaxial cable,
The second terminal is provided with a cylindrical portion that surrounds and shields the inner conductor terminal connected to the core wire,
The sheath of the end portion of the coaxial cable is removed to remove the shield conductor from the front portion of the first terminal and the rear portion of the second terminal, respectively, with the first terminal and the second terminal overlapping each other. A shield crimping part to be crimped to the exposed shield conductor exposed part is provided,
The shield crimping portion of the first terminal and the shield crimping portion of the second terminal have an uneven strip along the circumferential direction of the shield conductor exposed portion that fits together when the shield crimping portions are overlapped. Formed,
about.

According to the shield terminal having the above configuration (1), the shield crimping portion to be crimped to the shield conductor exposed portion of the coaxial cable has a double structure of the shield crimping portion of the first terminal and the shield crimping portion of the second terminal. It is possible to prevent the shield crimping part from opening due to secular change, and to maintain the connection stability between the shield conductor and the shield terminal. In addition, since the concave and convex strips of the respective shield crimping portions are fitted to each other at the portion where the shield crimping portion of the first terminal and the shield crimping portion of the second terminal are overlapped, the connection strength between the first terminal and the second terminal is increased. be able to. Therefore, the connection performance between the shield terminal and the coaxial cable can be improved.
In addition, since the shield crimping portion has a double structure, the necessary contact pressure can be secured without pressing the shield crimping portion too strongly against the shield conductor exposed portion. For this reason, even when the shield conductor is made of an aluminum foil, it is possible to prevent the insulator from being deformed, and to suppress a decrease in impedance. That is, when the shield conductor is composed of a braided wire, even if the shield crimping part is strongly crimped to the shield conductor exposed part, the braided wire plays a role of a cushion, but the insulator is rarely deformed. When the shield conductor is made of an aluminum foil, the aluminum foil hardly plays the role of a cushion, so that the insulator on the lower side of the shield conductor may be deformed, leading to a decrease in impedance. However, according to the shield terminal of the present invention, even when the shield conductor is made of an aluminum foil, it is possible to prevent the insulator from being deformed and suppress the impedance drop.
Moreover, according to this shield terminal, since the operation | work connected to the terminal part of a coaxial cable can be completed by a crimping | compression-bonding process, easy assembly | attachment to a coaxial cable is possible.

In order to achieve the above-described object, the shield terminal connection structure according to the present invention is characterized by the following (2) and (3).
(2) The shield terminal according to (1) is a connection structure of a shield terminal connected to a terminal portion of the coaxial cable in which an aluminum foil is used as the shield conductor,
The shield crimping portion of the first terminal is crimped to the shield conductor exposed portion of the end portion of the coaxial cable, and the sheath crimping portion of the first terminal is crimped to the sheath of the end portion of the coaxial cable;
The shield conductor exposed portion of the second terminal is exposed from above the shield crimp portion of the first terminal in a state in which the uneven crimp portion of the second terminal is fitted to the uneven strip of the shield crimp portion of the first terminal. Is crimped to
about.
(3) A shield terminal connection structure configured as described in (2) above,
A pair of wire barrels are respectively formed on the shield crimping portion of the first terminal and the shield crimping portion of the second terminal,
Each pair of wire barrels is bent so as to surround the shield conductor exposed portion until the tips thereof are opposed to each other, whereby the shield crimping portion of the first terminal and the shield crimping portion of the second terminal are formed in a cylindrical shape as a whole. It is crimped to the shield conductor exposed portion in the form.

According to the shield terminal connection structure configured as described in (2) above, the shield crimping portion that is crimped to the shield conductor exposed portion of the coaxial cable is the two of the shield crimping portion of the first terminal and the shield crimping portion of the second terminal. Since it has a heavy structure, it is possible to prevent the shield crimping portion from opening due to secular change, and to maintain the connection stability between the shield conductor and the shield terminal. In addition, in the portion where the shield crimping portion of the first terminal and the shield crimping portion of the second terminal are overlapped, the concave and convex stripes of each shield crimping portion are fitted to each other, so the connection strength between the first terminal and the second terminal Can be increased. Therefore, the connection performance between the shield terminal and the coaxial cable can be improved.
Moreover, since the shield crimping part has a double structure, the necessary contact pressure can be secured without strongly crimping the shield crimping part against the shield conductor exposed part. Therefore, even when the shield conductor is made of an aluminum foil, it is possible to prevent the insulator from being deformed and to suppress a decrease in impedance. Further, according to this shield terminal connection structure, all the operations for connecting to the end portion of the coaxial cable can be completed by the crimping process, and therefore the shield terminal can be easily assembled to the coaxial cable.
According to the shield terminal connection structure configured as described in (3) above, the pair of wire barrels are crimped onto one wire barrel without overlapping the tip of the other wire barrel, so excessive crimping force Does not hit the aluminum foil. In addition, since the pair of wire barrels are crimped to the shield conductor exposed portion in a cylindrical shape, high contact continuity can be ensured between the shield crimped portion and the shield conductor exposed portion.

  According to the shield terminal and the shield terminal connection structure of the present invention, high connection performance can be exhibited even when the shield conductor is connected to a coaxial cable made of aluminum foil.

  As shown in FIG. 2, the coaxial cable W to which the shield terminal of the embodiment is connected includes a core wire Wa, an insulator Wb covering the outer periphery of the core wire Wa, and an aluminum foil (shield conductor) covering the outer periphery of the insulator Wb. Wc and a sheath Wd covering the outer periphery of the aluminum foil Wc are provided.

  When a coaxial connector is attached to the terminal portion of the coaxial cable W, first, the core wire exposure is performed by removing the sheath Wd, the aluminum foil Wc, and the insulator Wb in this order from the distal end side to expose the core wire Wa. A portion WA, an insulator exposed portion WB that exposes the insulator Wb by removing the sheath Wd and the aluminum foil Wc, and a shield conductor exposed portion WC that exposes the aluminum foil Wc by removing the sheath Wd. Form.

  Then, as shown in FIG. 3, the core wire crimping portion 3 of the inner conductor terminal (inner terminal) 1 of the coaxial connector is crimped to the core wire exposed portion WA. On the front side of the core wire crimping portion 3, a cylindrical body 2 into which the inner conductor terminal of the counterpart coaxial connector is inserted is provided. Up to this point, the attachment of the inner conductor terminal 1 is completed, and then the process proceeds to the attachment of the shield terminal 8 of the embodiment shown in FIGS. 1 (a) and 1 (b).

  As shown in FIGS. 1 (a) and 1 (b), a shield terminal 8 as an outer conductor terminal has a cylindrical portion that surrounds and shields the inner conductor terminal 1 connected to the core wire exposed portion WA at the front. 21 is formed, and shield crimping parts 12 and 22 are formed in the middle part and are crimped to the shield conductor exposed part WC of the terminal part of the coaxial cable W, and are crimped to the sheath Wd of the terminal part of the coaxial cable W in the rear part. A sheath crimping portion 13 is formed. The shield terminal 8 includes a rear first terminal 10 (see FIGS. 5A and 5B) having a sheath crimping portion 13 and a front second terminal 20 having a cylindrical portion 21 (FIG. 6A). ) And FIG. 6 (b)).

  As shown in FIG. 1A, FIG. 1B, FIG. 5A, FIG. 5B, FIG. 6A, and FIG. Shield crimping portions 12 and 22 are provided on the rear portion of the terminal 20 so as to be crimped to the shield conductor exposed portion WC while being overlapped with each other. The shield crimping portions 12 and 22 of the first terminal 10 and the second terminal 20 are along the circumferential direction of the shield conductor exposed portion WC that fits to each other when the shield crimping portions 12 and 22 are overlapped. Concave and convex strips 12c and 22c are formed.

  Each of the shield crimping portions 12 and 22 before crimping has a U-shaped cross section having a pair of wire barrels 12a and 22a extending upward from both sides in the width direction of the bottom plate on which the shield conductor exposed portion WC is placed. It is formed in a shape. Similarly, the sheath crimping portion 13 of the first terminal 10 has a U-shaped cross section having two pairs of front and rear insulation barrels 13a extending upward from both sides in the width direction of the bottom plate on which the portion with the sheath Wd is placed. Is formed. FIG. 5A to FIG. 6B depict a state in which the shield crimping portions 12 and 22 and the sheath crimping portion 13 are crimped and bent.

  When connecting the shield terminal 8 of the embodiment to the terminal portion of the coaxial cable, first, the shield crimping portion 12 of the first terminal 10 is connected to the coaxial cable W as shown in FIGS. Crimp to the shield conductor exposed part WC of the terminal part. At that time, the pair of wire barrels 12a are bent inward so as to surround the shield conductor exposed portion WC until the tips of the wire barrels 12a face each other so that the tips of the wire barrels 12a face each other. In this way, the shield conductor is exposed to the exposed portion WC.

  Further, the sheath crimping portion 13 is crimped to a portion of the end portion of the coaxial cable W where the sheath Wd is present. Also with respect to the sheath crimping portion 13, the two pairs of insulation barrels 13a are bent inward so as to surround the portion where the sheath Wd is located so that the tips of the insulation barrels 13a face each other until the tips face each other. Then, the sheath crimping portion 13 is crimped to a portion where the sheath Wd is present, while the sheath crimping portion 13 is in a cylindrical shape.

  Next, as shown in FIG. 1A and FIG. 1B, while inserting the inner conductor terminal 1 into the through hole 6 of the dielectric 5 disposed inside the cylindrical portion 21 of the second terminal 20, The shield crimping portion 22 of the two terminals 20 is shielded from above the shield crimping portion 12 of the first terminal 10 in a state in which its own concave and convex strips 22 c are fitted to the concave and convex strips 12 c of the shield crimping portion 12 of the first terminal 10. Crimp to conductor exposed part WC. Also in this case, the shield conductor exposed portion WC is surrounded by the pair of wire barrels 22a from above the shield crimping portion 12 of the first terminal 10 until the tips of the wire barrels 22a are opposed to each other. The shield crimping portion 22 is crimped to the shield conductor exposed portion WC while bending the shield crimping portion 22 into a cylindrical shape. As described above, a coaxial connector connection structure (including a shield terminal connection structure) is completed.

  As described above, according to the shield terminal 8 and the connection structure thereof according to the embodiment, the shield crimping portion to be crimped to the shield conductor exposed portion WC of the coaxial cable W is the same as the shield crimping portion 12 on the first terminal 10 side and the second. Since it becomes a double structure with the shield crimping portion 22 on the terminal 20 side, it is possible to prevent the shield crimping portions 12 and 22 from opening due to aging, and the shield conductor (aluminum foil Wc) and the shield terminal 8 Connection stability can be maintained. Moreover, in the portion where the shield crimping portion 12 of the first terminal 10 and the shield crimping portion 22 of the second terminal 20 overlap, the concave and convex strips 12c and 22c of the shield crimping portions 12 and 22 are fitted to each other. The connection strength between the second terminal 20 and the second terminal 20 can be increased. Therefore, the connection performance between the shield terminal 8 and the coaxial cable W can be improved.

  In addition, the shield crimping portions 12 and 22 have a double structure, and the contact area with respect to the shield conductor exposed portion WC is suppressed by the concave and convex strips 12c and 22c of the shield crimping portions 12 and 22, so that the shield conductor exposed portion WC is protected. The required contact pressure can be secured while suppressing the contact pressure of the shield crimping portions 12 and 22. For this reason, even when the shield conductor is made of the aluminum foil Wc, it is possible to prevent the insulator Wb from being deformed, and to suppress a reduction in impedance. That is, when the shield conductor is composed of a braided wire, even if the shield crimping part is strongly crimped to the shield conductor exposed part, the braided wire plays a role of a cushion, but the insulator is rarely deformed. When the shield conductor is made of the aluminum foil Wc, the aluminum foil Wc hardly plays the role of a cushion, so that the insulator Wb below the aluminum foil Wc is deformed, which may cause a decrease in impedance. . However, according to the shield terminal 8 of the present invention, even when the shield conductor is made of the aluminum foil Wc, it is possible to prevent the insulator Wb from being deformed and suppress the impedance drop.

  Moreover, according to this shield terminal 8 and its connection structure, since the operation | work connected to the terminal part of the coaxial cable W can be completed by a crimping | compression-bonding process, the easy assembly | attachment to the coaxial cable W is possible.

  Further, according to the connection structure of the shield terminal 8, the pair of wire barrels 12a and 22a are pressure-bonded onto the one wire barrel 12a and 22a without overlapping the tips of the other wire barrels 12a and 22a. . For this reason, excessive crimping force is not applied to the aluminum foil Wc. Further, since the pair of wire barrels 12a and 22a are crimped to the shield conductor exposed portion WC in a cylindrical shape, high contact continuity is ensured between the shield crimp portions 12 and 22 and the shield conductor exposed portion WC. be able to.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, in the above embodiment, the case where the shield terminal is connected to the terminal portion of the coaxial cable W having the aluminum foil Wc as the shield conductor is shown. However, the shield terminal of the embodiment has the braided wire as the shield conductor. You may connect to the terminal part of a coaxial cable.
