You can stop, thereby the high-frequency characteristics of the connector in the case of electrically connecting a coaxial cable can be stabilized.

  As described above, the coaxial cable connector according to the present invention is a type for achieving an electrical connection of a coaxial cable (hereinafter simply referred to as “cable”), which is a flexible cable whose outer conductor is formed of a metal braided wire. The coaxial cable connector (hereinafter simply referred to as “connector”).

Hereinafter, the connector according to the present invention will be described in detail in Examples.
FIG. 1 is a conceptual perspective view showing a connector according to an embodiment of the present invention, and particularly shows a state of a connector electrically connected to a cable. 1 to 4 (described later), the same parts as those in FIGS. 5 to 8 are denoted by the same reference numerals.
FIG. 2 is a conceptual perspective view showing a state of the connector of FIG. 1 in an initial state, that is, a state before an operation of electrically connecting the coaxial cable.

  As shown in FIGS. 1 and 2, the connector 1 includes a connection terminal 2 and a metal shell 4.

  Among these, the shell 4 includes a shell main body 4a for supporting the connection terminal 2 via the insulating portion 3, a U-shaped cross-section shell bent portion 4b extending from the shell main body 4a, and a shell bent from the shell main body 4a. An outer conductor support portion 4c having a U-shaped cross section extending in a different direction from the portion 4b is provided.

  Among these, the outer conductor support portion 4c is composed of a pair of tongue pieces 4d having an L-shaped cross section. Further, a slit 16 is formed in the outer conductor support portion 4c between a pair of tongue pieces 4d having an L-shaped cross section. The pair of tongue pieces 4d having an L-shaped cross section are formed with planes 4g (FIG. 4) facing each other in a plane and in parallel (hereinafter, these planes are referred to as “planes”).

  In addition, a pair of gripping tongues 11 and a gripping part 12 composed of a pair of gripping tongues are formed in the shell bent portion 4b.

  The insulating portion 3 interposed between the shell 4 and the connection terminal 2 includes an insulating portion main body 3a that supports one tongue piece 2a and an insulating member disposed on the other contact 2b side with respect to the insulating portion main body 3a. It is comprised from the bending part 3b.

  Next, a method for electrically connecting the central conductor 34 of the cable 31 to the connection terminal 2 to the connector 1 and a method for electrically connecting the outer conductor 33 of the cable 31 to the shell 4 will be described. The structure of will be described in detail.

  In order to electrically connect the center conductor 34 of the cable 31 to the connector 1 to the connection terminal 2, as shown in FIG. 2, each of the outer conductor 33, the insulating portion 35, and the center conductor 34 of the coaxial cable as in the prior art. Part of each is exposed beforehand.

  The cable 31 used here is a flexible cable in which the outer conductor 33 is formed of a metal braided wire as described above.

Next, as shown by an arrow A in FIG. 2, the central conductor 34 of the cable 31 is disposed between the pair of tongues 2a and 2b, and the outer conductor 33 of the coaxial cable 31 is disposed in the outer conductor support portion 4c. To do.
Then, a part of the outer conductor 33 is covered with each L-shaped tongue piece 4d of the outer conductor support portion 4c, and the outer conductor 33 is supported by each L-shaped tongue piece 4d (described later). (See also FIG. 3 since it is also illustrated in FIG. 3)
Next, as shown by an arrow B in FIG. 2, the shell bent portion 4b and the insulating bent portion 3b are bent toward the outer conductor support portion 4c. Then, the connecting terminals 2 are elastically deformed by the bending forces of the shell bent portion 4b and the insulating bent portion 3b, and one tongue piece 2b presses the center conductor 34 against the other tongue piece 2a. For this reason, the center conductor 34 is gripped by the pair of tongue pieces 2a and 2b, whereby the center conductor 34 and the connection terminal 2 are electrically connected.

  FIG. 3 is a conceptual perspective view of the connector according to the embodiment of the present invention. In the middle of performing the electrical connection of the cable, in particular, the electrical connection between the central conductor and the connection terminal in the connector of FIG. It is a figure which shows a mode that this connector was turned over after drawing.

When the connector 1 of FIG. 2 is turned upside down, as shown in FIG. 3, the bent shell 4b between the pair of tongue pieces of the grip portion 12 is externally covered by the tongue pieces 4d each having an L-shaped cross section. A conductor 33 is disposed. The outer conductor 33 is covered with a tongue piece 4d and a shell bent portion 4b each having an L-shaped cross section.
Further, an outer jacket portion 32 of the coaxial cable 31 is disposed in the shell bent portion 4 b between the pair of gripping tongue pieces 11.

  Next, the pair of gripping tongue pieces of the gripping portion 12 are tilted toward the external conductor 33 side, and the external conductors 33 partially covered by the tongue pieces 4c each having an L-shaped cross section by the pair of gripping tongue pieces. The tongue piece 4d including the L-shaped cross section is gripped.

  Then, as shown in FIG. 4 which is a DD conceptual cross-sectional view of FIG. 1, the external conductor 33 (FIG. 2) and the shell 4 are electrically connected via the tongue pieces 4 d having the L-shaped cross section and the grip portion 12. .

Further, since the connector 1 grips the outer conductor 33 partially covered by the outer conductor support portion 4c as shown in FIG. 4 including the outer conductor support portion 4c, a vertical force ( The force in the direction indicated by the arrow X in FIG. 4 is applied to the cable 31 at the gripped portion via the tongue pieces 4d having L-shaped cross sections of the outer conductor support 4c. Therefore, the possibility that the cable 31 at the gripped position is deformed by the force from the vertical direction due to the grip is prevented as much as possible.
In particular, since the outer conductor support 4c is formed in a U-shaped cross section, when a vertical force (force in the direction indicated by an arrow X in FIG. 4) by gripping the outer conductor 33 is applied to the connector 1, The possibility that the cable 31 in the gripped portion is deformed is prevented as much as possible by the parallel planes 4g (FIG. 4) facing each other in the outer conductor support portion 4c.

  The outer conductor support 4c having a U-shaped cross section is composed of a pair of tongue pieces 4d having an L-shaped cross section. Therefore, as described above, when a vertical force (force in the direction of arrow X in FIG. 4) due to gripping of the outer conductor 33 is applied to the connector 1, there is a risk that the cable 31 in the gripped portion will be deformed. It can also be said that it is prevented as much as possible by the parallel planes 4g (FIG. 4) facing each other of the tongue pieces 4d having an L-shaped cross section.

  In this way, the possibility that the cable 31 of the portion gripped by the gripping portion 12 is deformed is prevented as much as possible. Therefore, in the connector 1, electrical connection is made to each of the central conductor 34 and the external conductor 33 of the cable 31. The high frequency characteristics of the connector 1 can be stabilized.

  In this connector 1, the outer conductor 33 is gripped (crimped) by the pair of gripping portions 12, but even if the gripping force is strong, there is a risk that the cable 31 in the gripped portion will be deformed. The high-frequency characteristics can be stabilized as much as possible by preventing as much as possible.

  In the connector 1, the outer conductor 33 is arranged in the outer conductor support portion 4 c as described above, so that the electrical connection between the center conductor 34 and the connection terminal 2 and the electrical connection between the outer conductor 33 and the shell 4 are performed. Therefore, the portion where the shell 4 directly supports the cable 31 is increased as compared with the conventional connector 41, so that the arrangement position of the cable 31 with respect to the connector 1 can be maintained at a fixed position. Therefore, in this connector 1, as compared with the conventional connector 41, the electrical connection between the center conductor 34 and the connection terminal 2 and the electrical connection between the external conductor 33 and the shell 4 can be ensured.

Moreover, in this connector 1, the holding | grip part 12 of the shell 4 hold | grips the external conductor 33, and, thereby, each bending force at the time of bending the shell bending part 4b and the insulation bending part 3b is hold | maintained. Therefore, the outer conductor 33 of the cable 31 is prevented from being detached from the connector 1, whereby the electrical connection between the center conductor 34 of the cable 31 and the connection terminal 2 can be maintained.
Furthermore, the gripping member 11 of the shell 4 grips the jacket portion 32 of the coaxial cable 31, thereby holding each bending force when the shell bent portion 4 b and the insulating bent portion 3 b are bent. Therefore, it is possible to further prevent the jacket portion 32 of the cable 31 from being detached from the connector 1, thereby further maintaining the electrical connection between the center conductor 34 of the cable 31 and the connection terminal 2.

  Further, in this connector 1, as shown in FIG. 1, two pairs of gripping tongue pieces for gripping the cable 31, that is, the gripping tongue piece of the gripping portion 12 for gripping the external conductor 33 and the jacket portion 32 are gripped. The cable 31 can be reliably supported only by providing the gripping tongue piece 11. Therefore, the number of parts can be reduced as compared with the conventional connector (FIG. 5) provided with three pairs of gripping tongues 53, 52, and 11 for gripping each of the insulating portion 35, the outer conductor 33, and the jacket portion 32. it can.

  Moreover, as shown in FIG. 1, the connector 1 connected to the cable 31 can be fitted to another connector. For example, the other connector is also a coaxial cable connector for electrically connecting a flexible cable made of an outer conductor of a braided wire, and a central conductor of a cable different from the cable described above in the same manner as the connector 1 An electrically connected contact portion and a shell for supporting the contact portion via an insulating portion and electrically connecting to an external conductor of the other cable in the same manner as the connector 1 are provided.

When a part of the shell of the other cable connector is fitted to the fitting portion 17 of the connector 1, the contact portion (male contact portion) of the other cable connector and the engaging portion of the connection terminal 2 of the connector 1 (Female contact portion) 2c is fitted, whereby the central conductor 34 of the cable 31 and the central conductor of the other cable connector can be electrically connected. Further, by fitting the part of the other cable connector with the fitting portion 17 of the connector 1, the outer conductor 33 of the cable 31 and the outer conductor of the other cable are connected to the shell of the other connector and Electrical connection can be made through the shell 4 of the connector 1.
The detailed structure of the connection terminal 2 is disclosed in Japanese Patent Laid-Open No. 2002-324636.

By the way, in this connector 1, when the pair of L-shaped tongue pieces 4 d of the outer conductor support portion 4 c is gripped by the grip portion 12 as described above, the grip force is mainly in the vertical direction (the arrow in FIG. 4). X direction) to the pair of L-shaped tongue pieces 4d.
As shown in FIG. 3, in this connector 1, a hole 4f is formed in the root portion of the shell 4 close to the center conductor 34 held by the connection terminal 2, that is, in the root portion of the outer conductor support portion 4c near the shell body 4a. Is formed. Therefore, the gripping part 12 grips the L-shaped tongue piece 4d at a position away from the shell body 4a from the vertical direction, and the gripping part 12 does not grip the root part from the vertical direction. Therefore, the operation of the shell 4 that occurs when a part of the shell of the other cable connector is fitted to the fitting portion 17 of the shell main body 4a of the connector 1, that is, the fitting portion 17 of the shell main body 4a has its diameter. An operation that attempts to widen is allowed. In other words, according to this connector 1, the spring fitting property in the above fitting can be ensured.

  In the conventional connector 41 (FIG. 5), when the insulating portion 35 is firmly gripped by the gripping tongue 53 in order to prevent the electrically connected cable 31 from being detached from the connector 1, the gripping tongue 53 is not insulated. 35, the root portion 20 (FIG. 7) is also gripped, so that the root portion 20 is also firmly gripped. Therefore, the operation performed when a part of the shell of the other cable connector is fitted to the fitting portion 17 of the shell main body 4a of the connector 1, that is, the fitting portion 17 of the shell main body 4a increases its diameter. There is a possibility that the operation of the shell 4 to be restricted is limited by the gripping of the root portion 20 by the gripping tongue 53 (the spring fitting property is impaired). However, according to the connector 1 of the present invention, the problem can be solved.

  Furthermore, in this connector 1, the slit 16 is formed along the longitudinal direction of the cable 31 in the outer conductor support 4c extending from the shell body 4a. When a part is fitted in the fitting groove 17 of the shell main body 4a of the connector 1, the operation of the shell 4 to allow the fitting portion 17 of the shell main body 4a to expand its diameter is allowed by this slit 16 as well. Accordingly, it is possible to further secure the fitting spring property in the fitting between the part and the fitting groove 17 of the shell body 4a.

  In the connector 1 described above, the shell bent portion 4b in contact with the outer conductor 33, the outer conductor support portion 4c in contact with the outer conductor 33, or the shell bent portion 4b in the portion indirectly holding the outer conductor 33 ( The grip portion 12 is not processed at all, but the shell bent portion 4b in contact with the external conductor 33, the external conductor support portion 4c in contact with the external conductor 33, or the external conductor 33 indirectly The shell bent portion 4b (including the grip portion 12) of the grip portion may be subjected to knurling (formation processing of a large number of grooves for supporting the outer conductor). The possibility that the conductor 33 is detached can be prevented as much as possible, and thereby the above-described electrical connection between the center conductor 34 and the outer conductor 33 of the cable 31 can be assured as possible. It can be.

  In the connector 1 described above, the shell bent portion 4b (including each gripping tongue piece 11) at a position in contact with the jacket portion 32 is not processed at all, but the shell bent portion at a position in contact with the jacket portion 32 is not provided. 4b (including each gripping tongue piece 11) may be knurled (processing for forming a large number of grooves for supporting the outer cover), and in this way, the outer cover 32 of the cable 31 from the connector 1 is formed. The possibility of disconnection can be prevented as much as possible, whereby the above-described electrical connection of the center conductor 34 and the outer conductor 33 of the cable 31 can be assured as much as possible.

  As described above, the connector for a coaxial cable according to the present invention prevents the deformation of the coaxial cable as much as possible when the outer conductor of the coaxial cable is gripped to make an electrical connection with the outer conductor. As a coaxial cable connector that stabilizes the high-frequency characteristics of the connector when the coaxial cable is electrically connected, it is useful for information devices such as mobile phones, personal computers and PDAs, and small electronic devices such as home appliances.
