When the outer conductor 12 and the outer conductor 22 come into contact with each other, they can conduct each other.

<Detailed Description of Receptacle 10 and Plug 20>
The inner conductor 11 is arranged so as to protrude from the vicinity of the central portion of the insulator 13. The extending direction of the inner conductor 11 is a direction orthogonal to the surface of the insulator 13 (surface opposite to the installation surface on the substrate surface 5a).

  The outer conductor 12 is a belt-like body erected on the peripheral edge portion of the insulator 13, and has a wall portion 12a that is a central portion and both end portions 12d that are tip portions from the wall portion 12a. Both end portions 12 d include both ends 12 b that are both ends of the outer conductor 12. In the outer conductor 12, an opening 12c through which the plug 20 can pass is formed between both end portions 12d of the belt-like body. The outer conductor 12 is separated from the inner conductor 11 and surrounds the side surface of the inner conductor 11. In other words, the outer conductor 12 extends from one end 12 b to the other end 12 b and stands on the peripheral edge of the insulator 13. The wall portion 12 a is arranged along the edge of the surface of the insulator 13. Both guide portions 12d are arranged outward so that the distance from each other extends toward the end 12b (the end on the side far from the wall portion 12a).

  The outer conductor 22 on the plug 20 side includes a wall portion (inner terminal outer conductor) 22a which is a side wall, and a plate-like lid portion 22e disposed on the wall portion 22a. The wall portion 22a has a shape in which a part of a cylindrical shape is opened. That is, the wall 22a is a belt-like body that surrounds the side surface of the inner conductor 21, and an opening 22c through which the inner conductor 11 of the receptacle 10 can pass between both ends (both ends) 22b that are both ends of the belt-like body. Is formed. The outer conductor 22 is separated from the inner conductor 21 and surrounds the side surface of the inner conductor 21. In other words, the outer conductor 22 extends from one end 22b to the other end 22b and stands on the peripheral edge of the lid portion 22e.

  The outer wall surface of the wall portion 22a and the inner wall surface of the outer conductor 12 of the receptacle 10 are fitted.

  As shown in FIG. 3, the inner conductor 11 of the receptacle 10 is exposed from the insulator 13 except for the vicinity of the lower end portion of the inner conductor 11, and the vicinity of the lower end portion is embedded in the vicinity of the insulator 13. The lower end portion of the inner conductor 11 is connected to the conductor 14 disposed inside the insulator 13 inside the insulator 13. One end of the conductor 14 is connected to the inner conductor 11 and is exposed from the insulator 13 on the way to the other end, and the other end is connected to a terminal, wiring, or the like provided on the substrate 5. The conductor 14 may be integrally formed of the same material as the inner conductor 11.

  On the plug 20 side, the tip end portion of the coaxial cable 30 is inserted into the plug 20 and fixed along the lid portion 22e. The front end portion of the coaxial cable 30 includes, in order from the front end, an inner conductor 31 disposed at the center, a dielectric 32 disposed outside the inner conductor 31, an outer conductor 33 disposed outside the dielectric 32, The outer skin 34 disposed outside the outer conductor 33 is exposed.

  The plug 20 includes a grip portion 24 and a support portion 25 that are arranged in order on the back surface of the lid portion 22e in the plug 20, and a dielectric 23. The dielectric 23 covers the inner conductor 31, the dielectric 32, and the outer skin 34 (part in the plug 20), which is the tip of the coaxial cable 30, including the grip portion 24 and the support portion 25. A portion of the dielectric 23 where the inner conductor 11 of the receptacle 10 is inserted is provided with a step. The inner conductor 21 of the plug 20 is disposed on the side wall of the step of the dielectric 23. The grip portion 24 grips the outer conductor 33, and the support portion 25 supports the outer skin 34. Thus, the coaxial cable 30 is attached along the back surface of the lid 22b. As shown in FIG. 1B, for example, the shape of the step of the dielectric 23 gradually increases from the portion where the inner conductor 21 is disposed to both ends 22b of the outer conductor 22. Shape.

  As shown in FIGS. 2 and 3, the inner conductor 21 of the plug 20 is disposed on the dielectric 23 so as to be separated from the outer conductor 22 and orthogonal to the outer conductor 22. The inner conductor 21 and the inner conductor 31 of the coaxial cable 30 are cross-connected so as to be orthogonal to each other.

  FIG. 4 is a perspective view showing the inner conductor 11 of the receptacle 10 and the inner conductor 21 of the plug 20. As shown in FIG. 4, each side surface of the inner conductor 11 and the inner conductor 21 has a shape that fits along each extending direction. As an example, the inner conductor 21 has a cylindrical shape. The inner conductor 11 has a concave shape such that the side surface of the inner conductor 21 is fitted. Thereby, while being able to make the inner conductors 11 and 21 contact reliably, a large contact area can be ensured. The inner conductor 11 may have a cylindrical shape, and the inner conductor 21 may have a concave shape such that the side surface of the inner conductor 11 is fitted.

  Thus, according to the coaxial connector 1, the outer conductor 12 of the receptacle 10 is a band-like body surrounding the side surface of the inner conductor 11, and the opening 12c through which the plug 20 can pass between both end portions 12d of the band-like body. Is formed. The wall portion 22a of the outer conductor 22 of the plug 20 is a band-like body surrounding the side surface of the inner conductor 21, and an opening 22c through which the inner conductor 11 of the receptacle 10 can pass is provided between both ends 22b of the band-like body. Is formed.

  When the plug 20 is inserted into the receptacle 10, the wall portion 22 a and the inner conductor 21 on the plug 20 side pass through the opening 12 c of the outer conductor 12 of the receptacle 10, and the inner conductor 11 of the receptacle 10 is connected to the outer conductor 22 of the plug 20. Through the opening 22c. Thereby, the plug 20 and the receptacle 10 can be fitted.

  For this reason, the plug 20 is moved in parallel with respect to the substrate surface 5a on which the receptacle 10 is installed, so that the outer conductor 22 and the inner conductor 21 on the plug 20 side are connected to the outer conductor through the openings 12c between both ends 12b of the outer conductor 12. 12, and the inner conductor 11 on the receptacle 10 side can be inserted into the outer conductor 22 through the opening 22 c between both ends 22 b of the outer conductor 22.

  In the state where the plug 20 and the receptacle 10 are fitted, the inner wall surface of the outer conductor 12 of the receptacle 10 and the outer wall surface of the wall portion 22a of the plug 20 are in contact with each other, and the inner conductor 11 of the receptacle 10 and the plug 20 are contacted. The inner conductor 21 is in contact with the inner conductor 21.

  As described above, the inner conductor 11 and the inner conductor 21 can be brought into contact with each other from the side surface through the opening portion 12c of the outer conductor 12 of the receptacle 10 and the opening portion 22c of the plug 20.

  6A is a cross-sectional view parallel to the substrate surface of the coaxial connector after contact, and FIG. 6B is a cross-sectional view orthogonal to the substrate surface of the coaxial connector after contact. 6A shows a cross section taken along line D-D 'in FIG. 6B, and FIG. 6B shows a cross section taken along line C-C' in FIG.

  By inserting the plug 20 into the receptacle 10, the plug 20 is fitted with the receptacle 10. Then, the side surface of the inner conductor 11 of the receptacle 10 and the side surface of the inner conductor 21 of the plug 20 can be brought into contact with each other, and the outer conductor 12 of the receptacle 10 and the outer conductor 22 of the plug 20 are brought into contact with each other. Can be conducted.

  For this reason, compared with the case where the inner conductor 11 and the inner conductor 21 are moved in the extending direction and brought into contact with each other, the inner conductor 11 and the inner conductor 21 are prevented from being damaged due to interference between the tips of the inner conductor 11 and the inner conductor 21. Can be easily and reliably brought into contact with each other. In this way, the coaxial connector 1 in which the receptacle 10 and the plug 20 are fitted can be obtained.

  FIG. 7 is a diagram illustrating a state in which the plug 20 is inserted into the receptacle 10 from the position where it is displaced.

  Further, in the coaxial connector 1, the outer conductor 12 of the receptacle 10 has both ends 12d of the belt-like body extending from the position of the opening 12c formed between the both ends 12d to the end 12d of the belt-like body. The distance between both ends is gradually increased. In other words, both guide portions 12d of the outer conductor 12 of the receptacle 10 are arranged outward so that the distance from each other extends toward both ends 12b. Specifically, each of the guide portions 12d is curved in a direction gradually separating from the wall portion 12a side to the both ends 12b side in a cross section parallel to the substrate surface 5a.

  For this reason, even when the plug 20 is moved parallel to the substrate surface 5a and inserted into the outer conductor 12 of the receptacle 10, the outer conductor 12 can be moved even if the plug 20 is moved to the opening 12c from a shifted position. One of the two guide portions 12d can receive the plug 20 that has been moved from a shifted position. As shown by the arrow in FIG. 7, the plug 20 can be guided into the opening 12c along the shape of the guide portion 12d with which the plug 20 is in contact. As a result, the plug 20 can be inserted into the receptacle 10 from the opening 12c.

  As described above, according to the coaxial connector 1, even when the size is reduced, it is possible to prevent the positional deviation when the receptacle 10 and the plug 20 are connected, and to connect the receptacle 10 and the plug 20. That is, the receptacle 10 and the plug 20 can be easily aligned.

  Further, the plug 20 is moved in parallel with the substrate surface 5 a and inserted into the receptacle 10. And the opening part 12c of the outer conductor 12 which is an inlet in which the plug 20 is inserted is opened in the direction parallel to the substrate surface 5a.

  In other words, the extending direction of the outer conductor 12 is a direction parallel to the substrate surface 5a, and the opening 12c is constituted by both guide portions 12d of the outer conductor 12.

  For this reason, it is possible to provide both guide portions 12d that are configured to guide the plug 20 into the receptacle 10 without increasing the height of the coaxial connector 1 (distance in a direction orthogonal to the substrate surface 5a).

  That is, according to the coaxial connector 1, it is possible to prevent an increase in height and to prevent a positional deviation between the plug 20 and the receptacle 10.

  For this reason, the coaxial connector 1 is a component of the coaxial connector 1 such as a substrate used in a small electronic device, a portable communication device such as a mobile phone terminal using the substrate, and a small electronic device such as a PDA or a small PC. It can be suitably used for parts and devices that are restricted in height.

  Here, since the plug 20 is moved in parallel with the substrate surface 5 a and inserted into the receptacle 10, it is necessary to first align the height of the plug 20 with the receptacle 10.

  Therefore, in the coaxial connector 1, a groove (fitting portion) 12f is formed on the inner wall surface of the outer conductor 12 of the receptacle 10. Further, a protruding portion (fitting portion) 22 f is formed on the outer wall surface of the wall portion 22 a of the outer conductor 22 of the plug 20. The groove portion 12f and the protruding portion 22f are shaped to fit with each other, and are formed in a groove shape that extends along the moving direction (direction parallel to the substrate surface 5a) when the plug 20 is fitted into the receptacle 10. The groove portion 12f is a substantially central portion of the inner surface of the outer conductor 12, and is formed along the direction in which the outer conductor 12 extends. As an example, the groove 12 f has a concave shape that is recessed from the inner surface of the outer conductor 12. The protrusion 22f is a substantially central portion of the outer surface of the outer conductor 12, and is formed along the direction in which the outer conductor 22 extends. As an example, the protrusion 22 f has a convex shape that protrudes from the outer surface of the outer conductor 22. The groove portion 12f and the protruding portion 22f are arranged substantially parallel to the substrate surface 5a.

  Thus, when the plug 20 is inserted into the receptacle 10, the groove portion 12f and the protruding portion 22f are fitted, and the plug 20 can be relatively moved along the groove portion 12f in parallel with the substrate surface 5a. For this reason, it is possible to prevent the displacement in the direction in which the outer conductors 12 and 22 extend, that is, the direction orthogonal to the substrate surface 5a, and to insert the plug 20 into the receptacle 10.

  Further, since the groove portion 12g and the protruding portion 22f are fitted even after the plug 20 and the receptacle 10 are fitted, it is possible to prevent the plug 20 from coming off from the receptacle 10 in the height direction. it can.

  Further, the groove 12f has a groove width (length in a direction perpendicular to the extending direction) gradually narrowed from the end 12b of the strip of the outer conductor 12.

  Accordingly, when the plug 20 is inserted into the receptacle 10, the protruding portion 22f is easily fitted into the groove portion 12f, and the plug 20 can be more reliably and easily prevented from being displaced in the direction perpendicular to the substrate surface 5a. Can be inserted into the receptacle 10.

  In addition, the groove part 12f and the protrusion part 22f should just be a shape which mutually fits, and an uneven | corrugated shape may be reverse. Further, the groove 12 f may be formed not only in the substantially central portion of the outer conductor 12 but also on the entire surface of the outer conductor 12 along the extending direction of the outer conductor 12. Similarly, the protruding portion 22 f may be formed not only in the substantially central portion of the outer conductor 22 but also in the direction in which the outer conductor 22 extends over the entire outer conductor 22.

[Embodiment 2]
FIG. 5 is a perspective view showing the inner conductor of the receptacle of the coaxial connector according to the second embodiment. The inner conductor 11 described in the first embodiment may have the shape of the inner conductor 41 illustrated in FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. The same applies to other embodiments thereafter.

  The inner conductor (outer terminal inner conductor) 41 is provided with a wall portion 41a formed with a recess for receiving the inner conductor 21, and a guide portion 41b for guiding the inner conductor 21 into the recess at the end of the opening of the recess. ing.

  Thus, when the inner conductor 21 and the inner conductor 41 are brought into contact with each other, even if the inner conductor 21 is moved to the inner conductor 41 from a position shifted, it can be received by one of the guide portions 41b. And the inner conductor 21 is inserted in the concave shape which the wall part 41a comprises along the shape of the guide part 41b by the guide part 41b which the inner conductor 21 contacted. As a result, the inner conductor 41 and the inner conductor 21 are connected. Thus, both the guide portions 41b can be guided so that the inner conductors 21 and 41 are fitted. For this reason, inner conductor 21 * 41 can be made to contact reliably. The inner conductor 11 may have a cylindrical shape, and the inner conductor 21 may have the shape of the inner conductor 41.

[Embodiment 3]
The third embodiment of the present invention will be described below with reference to FIG. FIG. 8 is a cross-sectional view parallel to the substrate surface of the coaxial connector according to the third embodiment.

  The coaxial connector 2 includes a receptacle (inner terminal) 50 and a plug (outer terminal) 60. The coaxial connector 2 is different from the coaxial connector 1 in that the receptacle 50 is configured to be fitted into the plug 60. As with the plug 20, the tip end portion of the coaxial cable 30 is inserted into the plug 60 and fixed.

  The receptacle 50 includes an inner conductor (inner terminal inner conductor) 51 and an outer conductor (inner terminal outer conductor) 52 instead of the inner conductor 11 and the outer conductor 12 of the receptacle 10. Other configurations of the receptacle 50 are the same as those of the receptacle 10. The plug 60 includes an inner conductor (outer terminal inner conductor) 61 and an outer conductor (outer terminal outer conductor) 62 instead of the inner conductor 21 and the outer conductor 22 of the plug 20. Other configurations of the plug 60 are the same as those of the plug 20. The outer conductor 52 and the outer conductor 62 have a fitting shape. The inner conductor 51 and the inner conductor 61 have a fitting shape.

  The outer conductor 52 has a shape in which a part of a cylindrical shape is opened. The outer conductor 52 has an opening 52c between both ends 52b. The outer conductor 52 is separated from the inner conductor 51 and surrounds the side surface of the inner conductor 51. In other words, the outer conductor 52 is disposed so as to extend from the one end 52 b to the other end 52 b of the both ends 52 b, be separated from the inner conductor 51, and surround the inner conductor 51.

  An opening 62c is formed between both ends 62b of the outer conductor 62. The outer conductor 62 has a wall portion 62a that is a central portion, and both guide portions 62d that are disposed at the tip of the wall portion 62a and that are both ends of the outer conductor 62 including both ends 62b.

  The outer conductor 62 is separated from the inner conductor 61 and surrounds the side surface of the inner conductor 61. In other words, the outer conductor 62 has a direction extending from the end 62b of one of the guide portions 62d to the end 62b of the other guide portion 62d of the both guide portions 62d, and is separated from the inner conductor 61. It is arranged to surround. The wall portion 62a is disposed along the edge of the surface of the insulator 13.

  The outer conductor 62 is such that both ends 62d of the band-shaped body are located between the positions of the openings 62c formed between the both ends 62 and the tip 62b of the band-shaped body. It has a shape that gradually increases. In other words, each of the two guide portions 62d is gradually curved away from each other from the wall 62a side to the both ends 62b side.

  Therefore, when the plug 60 is moved in parallel with respect to the substrate surface (not shown) on which the receptacle 50 is installed and the receptacle 50 is inserted into the plug 60, the relative position between the opening 62c of the plug 60 and the receptacle 50 is Even if they deviate, the receptacle 50 whose relative position is deviated in one of the two guide portions 62d of the outer conductor 62 can be received. Then, the receptacle 50 can be guided into the opening 62c along the shape of the guide portion 62d with which the receptacle 50 is in contact. As a result, the receptacle 50 can be inserted into the plug 60 from the opening 62c. For this reason, according to the coaxial connector 2, the receptacle 50 and the plug 60 can be easily aligned even if the size is reduced.

  The side surfaces of the inner conductor 51 and the inner conductor 61 are shaped to fit each other along their respective extending directions (directions orthogonal to the substrate surface on which the receptacle 50 is installed).

  As an example, the inner conductor 51 has a cylindrical shape. The inner conductor 61 has a concave shape such that the side surface of the inner conductor 61 is fitted. Thereby, while being able to make the inner conductors 51 and 61 contact reliably, a large contact area can be ensured.

  The grooves 12f and the protrusions 22f may be provided on the outer surface of the outer conductor 52 and the inner surface of the outer conductor 62.
