And a second assembly 3 in which a terminal holding body 33 for holding a plurality of second terminals 35 is attached to the frame 31. The first assembly 2 is attached to the first circuit board 7, and the second assembly 3 is attached to the second circuit board 8.

  In the connector 1, the first circuit board 7 and the second circuit board 8 are connected by attaching the first frame 21 and the second frame 31 together, and the first terminal 25 and The dielectric part 4 is sandwiched between the second terminal 35 and the second terminal 35. As a result, the connector 1 functions as a connector that performs signal transmission by capacitive coupling between the first circuit board 7 and the second circuit board 8.

  In the present embodiment, a circuit board is cited as an example of a flat circuit substrate, but the flat circuit substrate is not limited to this, and may be, for example, a flexible wiring substrate (FPC).

  2A to 2D are a perspective view, a front view, a back view, and a cross-sectional view of the first assembly 2. FIG. 3 is a perspective view of a terminal holding body 23 (hereinafter referred to as a terminal holding body 23A) according to the first example. 4A and 4B are a perspective view showing the first assembly 2 attached to the first circuit board 7, and an exploded perspective view thereof. In these descriptions, the second assembly 3 side is the front side, and the side attached to the first circuit board 7 is the back side.

  As shown in FIGS. 2A to 2D, the first frame 21 is formed in a rectangular frame shape, and includes a pair of long side portions 212 surrounding a rectangular through hole 21h penetrating from the front surface 2a to the back surface 2b. A pair of short sides 214 is provided. The first frame 21 has an extension 215 that extends outward from the center of each short side 214, and a retaining portion that is bent from the end to the surface 2a side (second frame 31 side). 216. The retaining portion 216 is for attaching the first frame 21 to the second frame 31, and its distal end portion 216 a is bent slightly outward to form a hook shape. The first frame 21 is formed by punching or bending a metal plate made of stainless steel or the like.

  The first frame 21 is fixed to the first circuit board 7 by bonding the long side part 212 and the extension part 215 to the first circuit board 7. Further, the long side portion 212 and the extending portion 215 may be soldered to a pad provided on the first circuit board 7.

  A terminal holding body 23A shown in FIG. 3 is disposed in the through hole 21h formed in the first frame 21.

The elastic body 273 is configured in a plate shape having a trapezoidal cross section when cut in the short direction, and the lower ends of both edge portions (end portions) 273e in the short direction are the edges of the plate portion 271. It is aligned with the portion 271e.

  Here, in the elastic member 27, since an elastic body 273 such as silicon rubber is laminated on the surface 271a of the plate-like portion 271 which is flexible such as polyimide but hardly elastically deforms in the in-plane direction, Elastic deformation in the direction is suppressed. On the other hand, since the elastic deformation in the thickness direction is caused by the elastic body 273 such as silicon rubber, the elastic member 27 including the plate-like portion 271 and the elastic body 273 exhibits elasticity selectively in the thickness direction. For this reason, the position shift of the 1st opposing conductor part 25a mentioned later and the 2nd opposing conductor part 35a can be suppressed.

  Moreover, the elastic body 273 is not formed in the longitudinal direction both ends of the surface 271a of the plate-shaped part 271, and these parts are the 1st flame | frame 21 as FIG. 2B and FIG. 2C show.

Specifically, the first terminal 25 includes a connection conductor portion 25b formed on the back surface 271b of the plate-like portion 271, a first opposing conductor portion 25a formed on the front surface 273a of the elastic body 273, and a plate-like portion. 271 and edge portions 271e and 273e of the elastic body 273, and a connecting conductor portion 25e for connecting the first opposing conductor portion 25a and the connecting conductor portion 25b.

  Here, since the connecting conductor portion 25e connects the first opposing conductor portion 25a and the connecting conductor portion 25b via the edges 271e and 273e, the first opposing conductor portion 25a and the connecting conductor portion 25b are The relative movement in the thickness direction is enabled according to the elasticity of the elastic body 273. Further, as shown in FIG. 4B, the connection conductor portion 25b is connected to a terminal (circuit side conductor portion) 75 that is electrically connected to a circuit provided on the first circuit board 7 by solder or the like. Moreover, the 1st opposing conductor part 25a is opposingly arranged with respect to the 2nd opposing conductor part 35b of the said 2nd terminal 35 so that it may mention later.

  In such a first terminal 25, the connection conductor portion 25b and the first opposing conductor portion 25a and the connecting conductor portion 25e are formed separately. Specifically, on the back surface 271b of the plate-like portion 271, for example, by selectively removing a metal film covering the entire back surface 271b, the connection conductor portion 25b extending to the edge portion 271e of the plate-like portion 271 is used. A first metal film is formed. This configuration is a so-called flexible printed circuit (FPC) configuration.

  On the other hand, as a first opposing conductor portion 25a and a connecting conductor portion 25e extending from the surface 273a of the elastic body 273 through the edge portion 271e of the plate-like portion 271 to the edge portion 273e of the elastic body 273 by sputtering or vapor deposition, for example. The second metal film is formed. The first metal film and the second metal film are connected at the edge portion 271e of the plate-like portion 271. According to this, since it is only necessary to perform sputtering or vapor deposition only on the surface 273a side of the elastic body 273, manufacture is easy.

  Moreover, after forming the first metal film and the second metal film, these are plated. This plating reinforces the continuity between the first metal film and the second metal film. That is, the continuity of the first opposing conductor portion 25a, the connecting conductor portion 25e, and the connecting conductor portion 25b is further enhanced.

  In addition, the 1st terminal 25 is not restricted to the said form, The connection conductor part 25e may be penetrated and formed in the plate-shaped part 271 and the elastic body 273. FIG. In this case, in order to enable the first opposing conductor portion 25a and the connection conductor portion 25b to move relative to each other in the thickness direction, it is preferable to form the connecting conductor portion 25e while avoiding the position immediately below them.

Specifically, the second terminal 35 includes a connecting conductor portion 35b formed on the back surface 37b of the insulating plate member 37, a second opposing conductor portion 35a formed on the front surface 37a of the insulating plate member 37, and It has a connecting conductor part 35e that is formed on the edge part 37e of the insulating plate member 37 and connects the connecting conductor part 35b and the second opposing conductor part 35a.

  Here, as shown in FIG. 8B, the connection conductor portion 35b is connected to a terminal (circuit side conductor portion) 85 that is electrically connected to a circuit provided on the second circuit board 8 by solder or the like. Further, the second opposing conductor portion 35a is disposed to face the first opposing conductor portion 25b of the first terminal 25, as will be described later. The connecting conductor portion 35e may be formed through the insulating plate member 37.

  The dielectric portion 4 is formed on the second opposing conductor portion 35 a of the second terminal 35. The dielectric portion 4 is made of, for example, a high dielectric ceramic such as barium titanate, and a thin film is formed on the second opposing conductor portion 35a by sputtering. Here, since the second terminal 35 is formed on the insulating plate-like member 37 made of a ceramic material or the like, the dielectric part 4 is provided on the second opposing conductor part 35a without the heat during sputtering being an obstacle. Can be formed into a thin film. However, the present invention is not limited to this, and the plate-like dielectric portion 4 may be bonded to the second opposing conductor portion 35a.

  In addition, reinforcing metal pads 39 are formed on both sides of the back surface 37b of the insulating plate member 37 in the longitudinal direction. As shown in FIG. 8B, these pads 39 correspond to the pads 89 formed on the surface of the second circuit board 8, and abut against them to disperse the force from the elastic body 273.

  The second frame 31 shown in FIGS. 6A to 6C is formed by subjecting a metal plate made of stainless steel or the like to punching or bending. On the back side of the inner end portion of the second frame 31 in the longitudinal direction (same as the longitudinal direction in FIGS. 5A and 5B), a recess 316 for attaching the terminal holding body 33 is formed. The terminal holding body 33 is bonded to the recess 316 via an adhesive paper 38 as shown in FIG. 7B.

  Further, an opening 31 h is formed in the second frame 31 at a position on the outer side in the longitudinal direction from the recess 316. A retaining portion 216 formed in the first frame 21 is inserted into the opening 31h. Further, a portion on the concave portion 316 side of the inner peripheral edge 311h of the opening 31h serves as an opposing wall when the retaining portion 216 is pressed by a distal end portion 314d of an elastic beam 314 described later. Further, the opening 31h is extended outward in the longitudinal direction with respect to the tip portions 314d, thereby ensuring a movable range of the tip portions 314d. Further, the inner peripheral edge 311h of the opening 31h has a tapered surface 311h that widens toward the front side.

  Further, the second frame 31 is provided with attachment portions 312 bent in a step shape toward the back side on both sides in the lateral direction across the recess 316 and the opening 31h. As shown in FIG. 8B, these attachment portions 312 correspond to the pads 89 formed on the surface of the second circuit board 8 and abut against them to disperse the force from the elastic body 273.

  In addition, the second frame 31 has portions extending outwardly in the lateral direction of the metal plate constituting the second frame 31 on the back side at positions outside the opening 31h in the longitudinal direction. A folded portion 313 formed by folding is formed. A portion on the back side of the folded portion 313 is an elastic beam (elastic beam) 314 for pressing the retaining portion 216 formed on the first frame 21. These elastic beams 314 extend from the outer edge side in the short direction toward the center, the outer edge side where the metal plate is folded back is the fixed end, and the tip side extending toward the center is the free end, It can be elastically deformed in the in-plane direction (that is, the longitudinal direction) intersecting the extending direction.

  In addition, the extending portion 314b extending from the outer edge side in the short direction toward the center of the elastic beam 314 has a narrower width toward the distal end side, so that the pressing force against the retaining portion 216 is appropriately set. It has become such a thing. In addition, a pressing direction portion 314 c extending in the pressing direction of the retaining portion 216 is formed on the distal end side of the elastic beam 314. The pressing direction portion 314c extends to the front of the inner peripheral edge 311h of the opening 31h serving as the opposing wall. Accordingly, the retaining portion 216 can be sandwiched with appropriate rigidity together with the inner peripheral edge 311h serving as the opposing wall.

  As shown in FIG. 6C, the end portion 314d of the pressing direction portion 314c is bent into a step shape on the front side and inserted into the opening 31h, and is disposed opposite to the inner peripheral edge 311h of the opening 31h. The retaining portion 216 formed on the first frame 21 is pressed by the end portion 314d. Further, the end 314d is formed in a taper shape in the pressing direction of the retaining portion 216. Among these, the taper surface 314e on the front side widens toward the front side together with the taper surface 311e formed on the inner peripheral edge 311h of the opening 31h, and the retaining portion 216 is guided therebetween.

As shown in FIG. 8B, the attachment portion 312 abuts on a pad 89 formed on the surface of the second circuit board 8. In addition, a gap is formed between the attachment portion 312 and the elastic beam 314, thereby ensuring a movable range of the elastic beam 314.

  The second frame 31 is fixed to the second circuit board 8 by soldering the mounting portion 312 to the pad 89 provided on the second circuit board 8. Further, the attachment portion 312 may be bonded to the second circuit board 8.

  As shown in FIG. 9B, the first frame 21 and the second frame 31 have a retaining portion 216 formed in the first frame 21 in an opening 31 h formed in the second frame 31. They are attached together by being inserted between the peripheral edge 311h and the end 314d of the elastic beam 314. Here, when the retaining portion 216 is inserted between the inner peripheral edge 311h of the opening 31h and the end portion 314d of the elastic beam 314, the retaining portion 216 is guided by the tapered surfaces 311e and 314e provided thereon, and is elastic. The end 314d of the beam 314 is retracted. The elastic beam 314 generates a force (elastic force) for pressing the retaining portion 216 when the end portion 314d is retracted. As a result, the distal end 216a of the retaining portion 216 engages with the end 314d of the elastic beam 314, and the lower portion of the distal end 216a is pressed by the end 314d of the elastic beam 314 against the inner peripheral edge 311h of the opening 31h. The stop 216 is fixed.

Specifically, the second plate-like portions 274 are arranged at predetermined intervals on both sides in the short direction with respect to the first plate-like portion 274, and each first terminal 25 is It extends from the first plate-like portion 274 to each second plate-like portion 275 along the short direction. The first terminals 25 are formed on the terminal forming surfaces 274a and 275b of the first plate-like portion 274 and the second plate-like portion 275. Further, the first plate-like portion 274 has a backing layer 274f that is lined with each first terminal 25 and extends to the second plate-like portion 275 side. In addition, each second plate-like portion 275 has pads 29 on both sides in the longitudinal direction.

  For example, the terminal forming body 26 selectively etches the resin layer with respect to the resin sheet with the metal film in which the metal film is formed on one whole surface of the resin sheet, and selectively etches the metal film. It can form by performing the process to do. That is, the first plate portion 274 and the two second plate portions 275 are formed by selectively etching the resin layer, and the first terminal 25 and the second plate portion 275 are formed by selectively etching the metal film. A pad 29 is formed. That is, such a terminal forming body 26 is formed as a so-called flexible printed circuit board (FPC).

  The terminal forming body 26 thus formed is attached so as to be wound around the elastic body 273 as shown in FIG. Specifically, the first plate-like portion 274 is bonded to the central portion in the short direction of the surface 273a of the elastic body 273, and extends from the first plate-like portion 274 to each second plate-like portion 274. The plurality of first terminals 25 are folded back at the edge portion 273e of the elastic body 273, and each second plate-shaped portion 274 is bonded to the back surface 273b of the elastic body 273. As described above, since the plurality of first terminals 25 can be arranged by attaching the terminal forming body 26 to the elastic body 273, the terminal holding body 23B can be easily formed.

  Further, the terminal forming body 26 is wound around the elastic body 273 so that the terminal forming surfaces 274 a and 275 b of the first plate-like portion 274 and the second plate-like portion 275 are directed outward with respect to the elastic body 273. . That is, in the first plate-like portion 274 and the second plate-like portion 275, the surfaces 274b and 275a opposite to the terminal forming surfaces 274a and 275b are bonded to the elastic body 273. Thereby, the terminal forming surface 274a of the first plate-like portion 274 is used as the surface of the terminal holding body 23B, and the terminal forming surface 275b of the second plate-like portion 275 is used as the back surface of the terminal holding body 23B.

  Further, in each first terminal 25 folded back at each edge portion 273e of the elastic body 273, a portion located on the surface 273a of the elastic body 273 is defined as the first opposing conductor portion 25a, and the edge portion 273e of the elastic body 273 is formed on the edge portion 273e. The part located is the connection conductor part 25e, and the part located on the back surface 273b of the elastic body 273 is the connection conductor part 25b. Here, since the connecting conductor portion 25e connects the first opposing conductor portion 25a and the connecting conductor portion 25b via the edge portion 273e of the elastic body 273, similarly to the terminal holding body 23A, The one opposing conductor portion 25a and the connecting conductor portion 25b are relatively movable in the thickness direction according to the elasticity of the elastic body 273. Further, unlike the above embodiment, in the present modification, the first terminal 25 can be integrally formed by forming the terminal forming body 26 as an FPC.

  Further, in the terminal holding body 23B formed in this way, the elastic body 273 is not formed at both ends in the longitudinal direction of the surface 275a of each second plate-like portion 275, and these portions are shown in FIG. As shown, it is adhered to the back side of each short side 214 of the first frame 21. As shown in FIGS. 14 and 15, the terminal holding body 23B attached to the first frame 21 has the terminal holding body 23A when the first frame 21 and the second frame 31 are attached together. Similarly, the first opposing conductor portion 25a and the second opposing conductor portion 35a can be pressed against the dielectric portion 4 by exerting an elastic force.

  Next, a terminal holder 23 (hereinafter referred to as a terminal holder 23C) according to a third example will be described. 16A to 16C are a perspective view, a front view, and a cross-sectional view of the first assembly 2 in which the terminal holding body 23C is disposed. 17A and 17B are cross-sectional views of the connector 1 including the terminal holding body 23C. In addition, about the structure which overlaps with the said terminal holding body 23A and the terminal holding body 23B, detailed description is abbreviate | omitted by attaching | subjecting the same number in a figure.

  As shown in FIGS. 16A to 16C, in the terminal holding body 23C, the pair of first opposing conductor portions 25x out of the plurality of first opposing conductor portions 25a protrudes to the front side (second opposing conductor portion 35a side). The protruding portion 251x is formed. On the other hand, as shown in FIGS. 17A and 17B, among the plurality of second opposing conductor portions 35a, the dielectric material 4 is formed in the second opposing conductor portion 35x corresponding to the first opposing conductor portion 25x. Absent. For this reason, the 1st opposing conductor part 25x and the 2nd opposing conductor part 35x are directly connected without the dielectric material 4 interposed. In addition, since the first opposing conductor portion 25x is provided with the protruding portion 251x, when the first frame 21 and the second frame 31 are attached to each other, the elastic member 27 is caused by the first opposing conductor portion 25x. The amount to be compressed is larger than in the case of the other first opposing conductor portion 25a. For this reason, the elastic force which the elastic member 27 pushes back the 1st opposing conductor part 25x becomes large compared with the case of the other 1st opposing conductor part 25a. For this reason, the crimping | compression-bonding force of the 1st opposing conductor part 25x and the 2nd opposing conductor part 35x is raised. Thereby, these 1st opposing conductor parts 25x and the 2nd opposing conductor part 35x can be used for the use different from high frequency uses, such as power supply, for example.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art.

  For example, as shown in FIG. 18, the terminal holding body 33 is omitted from the above configuration, and the terminal holding body 23 </ b> A is formed so as to be thick, and the first opposing conductor portion 25 a of the first terminal 25 and the second circuit are formed. The terminals 85 formed on the surface of the substrate 8 may be opposed to each other so as to sandwich the plate-like dielectric portion 4 therebetween. In this case, the terminal 85 corresponds to a “second opposing conductor portion”.

  For example, as shown in FIG. 19, without using the first frame 21 and the second frame 31, the terminal holding body 23 </ b> A and the second circuit board 8 are provided between the first circuit board 7 and the second circuit board 8. The first circuit board 7 and the second circuit board 8 may be fixed by fastening means 6 such as screws so as to interpose the plate-like dielectric portion 4 and press the terminal holding body 23A. . That is, the first opposing conductor portion 25a of the first terminal 25 and the terminal 85 formed on the surface of the second circuit board 8 are opposed to each other so that they sandwich the plate-like dielectric portion 4. . Also in this case, the terminal 85 corresponds to a “second opposing conductor portion”.
