Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described connector structure, the positions of the first conductor and the second conductor may be displaced due to variations in the dimensions of the first holder or the second holder. In such a case, the contact area between the first conductor and the second conductor becomes small, and as a result, it may be difficult to ensure conduction between the first conductor and the second conductor. If the width of the first conductor or the second conductor is increased, even if the positions of the first conductor and the second conductor are displaced, the contact area between the first conductor and the second conductor can be ensured, and conduction between the first conductor and the second conductor can be ensured. However, when the width of the first conductor or the second conductor is increased, disturbance of the impedance around the first conductor and the second conductor is likely to occur, and as a result, the communication performance may deteriorate.

[0005] An object of the present disclosure is to provide a connector structure and a connector capable of suppressing a decrease in communication performance while ensuring conduction.

Means for Solving the Problem

[0006] The connector structure of the present disclosure includes a first holder including a first tip surface, and a first connector having a first conductor held by the first holder, a second holder including a second tip surface facing the first tip surface, and a second connector having a second conductor held by the second holder. The first conductor has a first tip portion including a first connection surface exposed from the first tip surface, and a first main body portion located on the side opposite to the second connector with respect to the first tip portion. The second conductor includes a second connection surface exposed from the second tip surface and facing the first connection surface. The width of the first connection surface when viewed in the direction intersecting the first tip surface is formed to be larger than the width of the second connection surface when viewed in the direction intersecting the second tip surface. The dielectric constant of the first region surrounding the first tip portion in the first holder is smaller than the dielectric constant of the second region surrounding the second conductor in the second holder.

Embodiments for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, the contents of the embodiments of the present disclosure will be listed and described.

[0010] The connector structure of the present disclosure is "[1] a first connector having a first holder including a first tip surface and a first conductor held by the first holder, and a second connector having a second holder including a second tip surface facing the first tip surface and a second conductor held by the second holder, wherein the first conductor has a first tip portion including a first connection surface exposed from the first tip surface and a first main body portion located on the side opposite to the second connector with respect to the first tip portion, the second conductor includes a second connection surface exposed from the second tip surface and facing the first connection surface, the width of the first connection surface as viewed in the direction intersecting the first tip surface is formed larger than the width of the second connection surface as viewed in the direction intersecting the second tip surface, and the dielectric constant of a first region of the first holder surrounding the first tip portion is smaller than the dielectric constant of a second region of the second holder surrounding the second conductor, a connector structure."

[0011] In the connector structure described in the above [1], the width of the first connection surface is formed larger than the width of the second connection surface. As a result, even if the positions of the first conductor and the second conductor are displaced, the contact area between the first conductor and the second conductor is ensured, and thus the electrical connection between the first conductor and the second conductor is ensured. Further, the dielectric constant of a first region of the first holder surrounding the first tip portion is smaller than the dielectric constant of a second region of the second holder surrounding the second conductor. As a result, the disturbance of the impedance around the first tip portion and the second conductor is suppressed, and thus the deterioration of the communication performance is suppressed. Therefore, according to this connector structure, it is possible to suppress the deterioration of the communication performance while ensuring the electrical connection.

[0012] The connector structure of the present disclosure may be "[2] the width of the first connection surface when viewed from a direction intersecting the first tip surface is formed to be larger than the width of the first main body portion when viewed from a direction intersecting the first tip surface, and the dielectric constant of the first region is smaller than the dielectric constant of the third region surrounding the first main body portion in the first holder, the connector structure according to [1] above." Thereby, the contact area between the first conductor and the second conductor is ensured, and the disturbance of the impedance around the first conductor is suppressed.

[0013] The connector structure of the present disclosure may be "[3] the first region contains air, and each of the second region and the third region contains resin, the connector structure according to [2] above." Thereby, the disturbance of the impedance around the first conductor and the second conductor is preferably suppressed.

[0014] The connector structure of the present disclosure may be "[4] the first tip portion is integrally formed with the first main body portion, the connector structure according to any one of [1] to [3] above." Thereby, the number of parts of the connector structure is reduced.

[0015] The connector structure of the present disclosure may be "[5] the first tip portion is separately formed from the first main body portion, the connector structure according to any one of [1] to [3] above." Thereby, the degree of freedom in the design of each of the first tip portion and the first main body portion is improved.

[0016] The connector structure of the present disclosure may be "[6] the first holder includes a plurality of first insertion holes that open to the first tip surface, the first conductor is each of a plurality of electric wires of a flexible flat cable, and each of the plurality of electric wires is inserted into each of the plurality of first insertion holes, the connector structure according to any one of [1] to [5] above." Thereby, the electrical continuity of each electric wire of the flexible flat cable is ensured, and the deterioration of the communication performance of the flexible flat cable is suppressed.

[0017] The connector structure of the present disclosure may be "[7] The second holding body includes a plurality of second insertion holes that open to the second front end surface, the second conductor is each of the plurality of conductors, and each of the plurality of conductors is inserted into each of the plurality of second insertion holes, the connector structure described in the above [6]." Thereby, the electrical continuity of each electric wire of the flexible flat cable is ensured, and a decrease in the communication performance of the flexible flat cable is suppressed.

[0018] The connector of the present disclosure is "[8] A holding body including a front end surface and a rear end surface opposite to the front end surface, and a conductor held by the holding body, the conductor having a front end portion including a connection surface exposed from the front end surface, and a main body portion located on the rear end surface side with respect to the front end portion, the width of the connection surface when viewed from a direction intersecting the front end surface is formed larger than the width of the main body portion when viewed from a direction intersecting the front end surface, and the dielectric constant of a region of the holding body that surrounds the front end portion is smaller than the dielectric constant of a region of the holding body that surrounds the main body portion, the connector."

[0019] In the connector described in the above [8], the width of the connection surface of the front end portion is formed larger than the width of the main body portion. Thereby, even if the position of the conductor and the position of the conductor of the mating connector are displaced, as a result, the contact area between the conductor and the conductor of the mating connector is ensured, and electrical continuity between the conductor and the conductor of the mating connector is ensured. Further, the dielectric constant of a region of the holding body that surrounds the front end portion is smaller than the dielectric constant of a region of the holding body that surrounds the main body portion. As a result, disturbance of the impedance around the conductor is suppressed, and a decrease in communication performance is suppressed. Therefore, according to this connector, it is possible to suppress a decrease in communication performance while ensuring electrical continuity.

The present disclosure is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In the description of the drawings, the same reference numerals are given to the same elements, and redundant descriptions are omitted.

[0021] FIG. 1 is a cross-sectional view of the connector structure of the present embodiment. As shown in FIG. 1, the connector structure 1 includes a first connector 2 and a second connector 3. The first connector 2 is, for example, a plug connector. The second connector 3 is, for example, a receptacle connector.

[0022] The first connector 2 has a first holder 21 and a plurality of first conductors 22. The first holder 21 has a first housing 211 and a first ferrule 212. The first housing 211 has, for example, a rectangular cylindrical shape. The first ferrule 212 is provided inside the first housing 211. The first ferrule 212 contains a resin material such as, for example, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), or polyetherimide (PEI).

[0023] The first holder 21 includes a front end surface (first front end surface) 21a, a front end surface 21b, a rear end surface 21c, a side surface 21d, and a plurality of insertion holes (first insertion holes) 21e. Each of the front end surface 21a and the front end surface 21b is, for example, a flat surface intersecting in the Z-axis direction. The front end surface 21a and the front end surface 21b face the same direction.

[0024] The front end surface 21a is formed by the first ferrule 212. The front end surface 21a has, for example, a rectangular shape when viewed from the Z-axis direction. The front end surface 21a is recessed more than the front end surface 21b. The front end surface 21a is located on the rear end surface 21c side with respect to the front end surface 21b. The front end surface 21b is formed by the first housing 211. The front end surface 21b has, for example, a rectangular frame shape when viewed from the Z-axis direction. The front end surface 21b surrounds the front end surface 21a when viewed from the Z-axis direction.

[0025] The rear end surface 21c is formed by the first housing 211 and the first ferrule 212. The rear end surface 21c is, for example, a flat surface intersecting the Z-axis direction. The rear end surface 21c faces the side opposite to the front end surface 21a and the front end surface 21b. The side surface 21d is formed by the first housing 211. The side surface 21d has, for example, a cylindrical shape extending along the Z-axis direction. The side surface 21d is located on the side opposite to the rear end surface 21c with respect to the front end surface 21a. The side surface 21d surrounds the front end surface 21a when viewed from the Z-axis direction. The side surface 21d faces the inside of the first housing 211 when viewed from the Z-axis direction.

[0026] The plurality of insertion holes 21e are formed in the first ferrule 212. Each insertion hole 21e extends, for example, along the Z-axis direction. Each insertion hole 21e has, for example, a cylindrical shape. In the present embodiment, each insertion hole 21e penetrates the first ferrule 212. That is, each insertion hole 21e opens at each of the front end surface 21a and the rear end surface 21c.

[0027] FIG. 2 is a front view of the first connector 2. As shown in FIGS. 1 and 2, in the present embodiment, the first holder 21 includes two rows of insertion holes 21e. The first row of insertion holes 21e and the second row of insertion holes 21e are adjacent to each other in the Y-axis direction. The insertion holes 21e in each row are arranged along the X-axis direction.

[0028] Each first conductor 22 has, for example, a circular shape in a cross-section along the XY plane. The first conductor 22 is, for example, each of a plurality of electric wires of a flexible flat cable (FFC). Each first conductor 22 is inserted into each insertion hole 21e. Thereby, the plurality of first conductors 22 are held by the first holder 21. The material of the first conductor 22 is, for example, soft copper or the like.

[0029] As shown in FIG. 1, the second connector 3 has a second holder 31 and a plurality of second conductors 32. The second holder 31 has a second housing 311 and a second ferrule 312. The second housing 311 has, for example, a rectangular tubular shape. The second ferrule 312 is provided inside the second housing 311. The second ferrule 312 contains a resin material such as, for example, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), or polyetherimide (PEI).

[0030] The second holder 31 includes a front end face (second front end face) 31a, a front end face 31b, a rear end face 31c, a side face 31d, and a plurality of insertion holes (second insertion holes) 31e. Each of the front end face 31a and the front end face 31b is, for example, a flat face intersecting the Z-axis direction. The front end face 31a and the front end face 31b face the same direction.

[0031] The front end face 31a is formed by the second ferrule 312. The front end face 31a has, for example, a rectangular shape when viewed from the Z-axis direction. The front end face 31a protrudes more than the front end face 31b. The front end face 31a is located on the side opposite to the rear end face 21c with respect to the front end face 31b. The front end face 31b is formed by the second housing 311. The front end face 31b has, for example, a rectangular frame shape when viewed from the Z-axis direction. The front end face 31b surrounds the front end face 31a when viewed from the Z-axis direction. The side face 31d faces the outside of the second housing 311 when viewed from the Z-axis direction.

[0032] The rear end face 31c is formed by the second housing 311 and the second ferrule 312. The rear end face 31c is, for example, a flat face intersecting the Z-axis direction. The rear end face 31c faces the side opposite to the front end face 31a and the front end face 31b. The side face 31d is formed by the second ferrule 312. The side face 31d has, for example, a tubular shape extending along the Z-axis direction. The side face 31d is located on the side opposite to the rear end face 31c with respect to the front end face 31b. The side face 31d surrounds the front end face 31a when viewed from the Z-axis direction.

[0033] The plurality of insertion holes 31e are formed in the second ferrule 312. Each insertion hole 31e extends, for example, along the Z-axis direction. Each insertion hole 31e has, for example, a cylindrical shape. In the present embodiment, each insertion hole 31e penetrates the second ferrule 312. That is, each insertion hole 31e opens at each of the front end surface 31a and the rear end surface 31c.

[0034] FIG. 3 is a front view of the second connector 3. As shown in FIGS. 1 and 3, in the present embodiment, the second holder 31 includes two rows of insertion holes 31e. The first row of insertion holes 31e and the second row of insertion holes 31e are adjacent to each other in the Y-axis direction. The insertion holes 31e in each row are arranged along the X-axis direction.

[0035] Each second conductor 32 has, for example, a circular shape in a cross-section along the XY plane. Each second conductor 32 is inserted into each insertion hole 31e. Thereby, the plurality of second conductors 32 are held by the second holder 31. The material of the second conductor 32 is, for example, a copper alloy or the like.

[0036] The first connector 2 is connected to the second connector 3. Specifically, the first connector 2 is fitted to the second connector 3 such that the front end surface 21a of the first holder 21 faces the front end surface 31a of the second holder 31, the front end surface 21b of the first holder 21 faces the front end surface 31b of the second holder 31, and the side surface 21d of the first holder 21 surrounds the side surface 31d of the second holder 31. The side surface 21d and the side surface 31d are in contact with each other. When the first connector 2 is connected to the second connector 3, the first conductor 22 and the second conductor 32 come into contact with each other. Thereby, electrical continuity between the first conductor 22 and the second conductor 32 is achieved.

[0037] FIG. 4 is a partially enlarged view of FIG. 1. As shown in FIG. 4, the first conductor 22 has a first tip portion 221 and a first main body portion 222. In the present embodiment, the first tip portion 221 is a region of the first conductor 22 that is located on the side opposite to the rear end surface 21c with respect to the front end surface 21a. The first tip portion 221 protrudes from the front end surface 21a. The first tip portion 221 is located between the front end surface 21a and the front end surface 31a. The first tip portion 221 has, for example, a disk shape. The first tip portion 221 is formed, for example, by plastic deformation of the tip of the first conductor 22.

[0038] The first tip portion 221 includes a first connection surface 22a that is exposed from the front end surface 21a. The first connection surface 22a is located on the side opposite to the rear end surface 21c with respect to the front end surface 21a. The first connection surface 22a is, for example, a flat surface that intersects the Z-axis direction. The first connection surface 22a has, for example, a circular shape when viewed from the Z-axis direction.

[0039] In the present embodiment, the first main body portion 222 is a region of the first conductor 22 that is located on the side opposite to the first tip portion 221 with respect to the front end surface 21a. The first main body portion 222 is located on the side opposite to the second connector 3 with respect to the first tip portion 221. The first main body portion 222 is disposed inside the insertion hole 21e. The first main body portion 222 has, for example, a circular shape in a cross section along the XY plane. The first tip portion 221 and the first main body portion 222 are integrally formed of the same material. Each of the first tip portion 221 and the first main body portion 222 is a predetermined region of the first conductor 22 that is a single component.

[0040] The width of the first connection surface 22a (the diameter of the first connection surface 22a in the present embodiment) when viewed from the Z-axis direction (the direction intersecting the front end surface 21a) is larger than the width of the first main body portion 222 (the diameter of the first main body portion 222 in the present embodiment) when viewed from the direction intersecting the Z-axis direction. The width of the first connection surface 22a is, for example, about 0.5 mm to 1.0 mm. The width of the first main body portion 222 is, for example, about 0.2 mm to 0.5 mm. The length of the first tip portion 221 in the Z-axis direction is, for example, about 0.1 mm to 0.3 mm.

[0041] The second conductor 32 includes a second connection surface 32a that is exposed from the tip surface 31a. The second connection surface 32a is, for example, a flat surface that intersects in the Z-axis direction. In the present embodiment, the second connection surface 32a is flush with the tip surface 31a. The second connection surface 32a has, for example, a circular shape when viewed from the Z-axis direction (the direction intersecting the tip surface 31a). The second connection surface 32a faces the first connection surface 22a. When viewed from the Z-axis direction, the width of the first connection surface 22a is larger than the width of the second connection surface 32a (the diameter of the second connection surface 32a in the present embodiment). In the present embodiment, the width of the second connection surface 32a is the same as the width of the first main body portion 222. In the present embodiment, the width (the diameter of the second conductor 32 in the present embodiment) of the second conductor 32 is the same as the width of the first main body portion 222. The width of the second connection surface 32a (the width of the second conductor 32) is, for example, about 0.2 mm to 0.5 mm.

[0042] The first tip portion 221 is surrounded by the first region R1 of the first holder 21. The first region R1 is a region of the first holder 21 that surrounds the first tip portion 221 when viewed from the Z-axis direction and overlaps the first tip portion 221 when viewed from the direction along the XY plane. In the present embodiment, the first region R1 is a region between the tip surface 21a and the first connection surface 22a of the first tip portion 221. In the present embodiment, the first region R1 contains air. In the present embodiment, the first region R1 is filled with air.

[0043] The second conductor 32 is surrounded by the second region R2 of the second holder 31. The second region R2 is a region of the second holder 31 that surrounds the second conductor 32 when viewed from the Z-axis direction and overlaps the second conductor 32 when viewed from the direction along the XY plane. In the present embodiment, the second region R2 is a region between the tip surface 31a and the rear end surface 31c. In the present embodiment, the second region R2 is formed by the second ferrule 312.

[0044] The first main body portion 222 is surrounded by the third region R3 of the first holder 21. The third region R3 is a region that surrounds the first main body portion 222 when viewed from the Z-axis direction and overlaps the first main body portion 222 when viewed from the direction along the XY plane in the first holder 21. In the present embodiment, the third region R3 is a region between the front end face 21a and the rear end face 21c. In the present embodiment, the third region R3 is formed by the first ferrule 212.

[0045] The dielectric constant of the first region R1 is smaller than the dielectric constants of the second region R2 and the third region R3, respectively. In the present embodiment, the dielectric constant of the second region R2 is the same as the dielectric constant of the third region R3. The dielectric constant of the first region R1 is, for example, about 1.0 to 2.0. In the present embodiment, the dielectric constant of the first region R1 is about 1.0. The dielectric constant of the second region R2 is, for example, about 1.5 to 5.0. The dielectric constant of the third region R3 is, for example, about 1.5 to 5.0. In the present embodiment, the dielectric constant refers to the relative dielectric constant.

[0046] As described above, in the connector structure 1, the width of the first connection surface 22a is formed larger than the width of the second connection surface 32a. As a result, even if the positions of the first conductor 22 and the second conductor 32 are displaced (for example, even if the center lines of the first conductor 22 and the second conductor 32 are displaced from each other), the contact area between the first conductor 22 and the second conductor 32 is ensured, and thus conduction between the first conductor 22 and the second conductor 32 is ensured. Further, the dielectric constant of the first region R1 that surrounds the first tip portion 221 in the first holder 21 is smaller than the dielectric constant of the second region R2 that surrounds the second conductor 32 in the second holder 31. As a result, the disturbance of the impedance around the first tip portion 221 and the second conductor 32 is suppressed, and thus the deterioration of the communication performance is suppressed. Therefore, according to the connector structure 1, it is possible to suppress the deterioration of the communication performance while ensuring conduction.

[0047] When viewed from the Z-axis direction, the width of the first connection surface 22a is formed to be larger than the width of the first main body portion 222 when viewed from the Z-axis direction. The dielectric constant of the first region R1 is smaller than the dielectric constant of the third region R3 that surrounds the first main body portion 222 in the first holder 21. Thereby, the contact area between the first conductor 22 and the second conductor 32 is ensured, and the disturbance of the impedance around the first conductor 22 is suppressed.

[0048] The first region R1 contains air. Each of the second region R2 and the third region R3 contains resin. Thereby, the disturbance of the impedance around the first conductor 22 and the second conductor 32 is preferably suppressed.

[0049] The first tip portion 221 is formed integrally with the first main body portion 222. Thereby, the number of parts of the connector structure 1 is reduced.

[0050] The first holder 21 includes a plurality of insertion holes 21e that open to the tip surface 21a. The first conductor 22 is each of a plurality of electric wires of a flexible flat cable. Each first conductor 22 is inserted into each insertion hole 21e. Thereby, the electrical continuity of each electric wire of the flexible flat cable is ensured, and the deterioration of the communication performance of the flexible flat cable is suppressed.

[0051] The second holder 31 includes a plurality of insertion holes 31e that open to the tip surface 31a. Each second conductor 32 is inserted into each insertion hole 31e. Thereby, the electrical continuity of each electric wire of the flexible flat cable is ensured, and the deterioration of the communication performance of the flexible flat cable is suppressed.

[0052] [Modified Example] FIG. 5 is a cross-sectional view of the connector structure according to the first modification. As shown in FIG. 5, the first tip portion 221 of the first conductor 22 may be formed separately from the first main body portion 222 of the first conductor 22. Specifically, a part of the first main body portion 222 protrudes from the front end surface 21a. The first tip portion 221 may be a lid member provided at the tip of the first main body portion 222. The first tip portion 221 has, for example, a cylindrical shape. One end of the first tip portion 221 is open, and the other end of the first tip portion 221 is closed. The first connection surface 22a is formed by the outer surface of the closing wall of the first tip portion 221. The first tip portion 221 may be, for example, a solder material or the like formed at the tip of the first main body portion 222. The material of the first tip portion 221 may be different from the material of the first main body portion 222. According to such a configuration, the degree of freedom in the design of each of the first tip portion 221 and the first main body portion 222 is improved.

[0053] FIG. 6 is a cross-sectional view of the connector structure according to the second modification. As shown in FIG. 6, the width of the first main body portion 222 of the first conductor 22 may be the same as the width of the first tip portion 221 of the first conductor 22. In this case, the first connection surface 22a may be flush with the front end surface 21a. In this case, the dielectric constant of the third region R3 may be the same as the dielectric constant of the first region R1. The dielectric constant of each of the first region R1 and the third region R3 may be smaller than the dielectric constant of the second region R2. The first region R1 may be formed by the first ferrule 212 in the same manner as the third region R3. The first region R1 may be integrally formed of the same material as the third region R3.

[0054] In the embodiment, the first connector 2 is a plug connector and the second connector 3 is a receptacle connector, but the first connector 2 may be a receptacle connector and the second connector 3 may be a plug connector. In this case, the second conductor 32 may be each of a plurality of electric wires of a flexible flat cable.

[0055] In the embodiment, although the first region R1 was filled with air, the first region R1 may contain, for example, a dielectric constant adjuster or the like. The first region R1 may be filled with a dielectric constant adjuster or the like. The dielectric constant adjuster contains, for example, a material such as rubber. It is sufficient that the dielectric constant of the first region R1 is smaller than the dielectric constant of the second region R2.

[0056] In the embodiment, each insertion hole 21e had a cylindrical shape, and the first conductor 22 had a circular shape in a cross section along the XY plane. However, the insertion hole 21e may have, for example, a rectangular cylindrical shape, and the first conductor 22 may have, for example, a rectangular shape in a cross section along the XY plane. In the embodiment, each insertion hole 31e had a cylindrical shape, and the second conductor 32 had a circular shape in a cross section along the XY plane. However, the insertion hole 31e may have, for example, a rectangular cylindrical shape, and the second conductor 32 may have, for example, a rectangular shape in a cross section along the XY plane.

[0057] In the embodiment, the first holder 21 included two rows of insertion holes 21e. However, the first holder 21 may include, for example, one row or three or more rows of insertion holes 21e. In the embodiment, the second holder 31 included two rows of insertion holes 31e. However, the second holder 31 may include, for example, one row or three or more rows of insertion holes 31e.
