Description

   Connector, connector group and manufacturing method of connector   

The present invention relates to a connector, a connector group, and a method for manufacturing the connector, and more particularly, to a connector having a center conductor and an outer conductor, a connector group, and a method for manufacturing the connector.

As a conventional invention of a connector, for example, a coaxial connector plug and a coaxial connector socket described in Patent Document 1 are known. FIG. 17 is a cross-sectional structure diagram of the coaxial connector plug 500 and the coaxial connector socket 600 described in Patent Document 1. As shown in FIG. Hereinafter, for convenience, the up-down direction and the left-right direction in FIG. 17 are defined as the up-down direction and the left-right direction.

The coaxial connector plug 500 includes an outer conductor 512, a center conductor 514, and an insulator 516. When viewed from the lower side, the outer conductor 512 has a shape in which a part of a ring is cut out (hereinafter referred to as a C-shape). The center conductor 514 is arranged at the center of the outer conductor 512 when viewed from the lower side. The insulator 516 fixes the relative position of the outer conductor 512 and the center conductor 514.

The coaxial connector socket 600 includes an outer conductor 612 and a center conductor 614. The outer conductor 612 has a ring shape when viewed from the upper side. The center conductor 614 is arranged at the center of the outer conductor 612 when viewed from the upper side. The insulator 616 fixes the relative position of the outer conductor 612 and the center conductor 614.

The coaxial connector plug 500 as described above is connected to the coaxial connector socket 600 from the upper side. At this time, the external conductor 612 is inserted into the external conductor 512. The outer conductor 512 is C-shaped. Therefore, the outer conductor 512 is elastically deformed so that the gap is slightly widened when the outer conductor 612 is inserted. Thereby, the inner peripheral surface of the outer conductor 512 contacts the outer peripheral surface of the outer conductor 612, and the outer conductor 512 holds the outer conductor 612.

However, the inventors of the present invention found that in the coaxial connector plug 500 and the coaxial connector socket 600 described in Patent Document 1, noise may enter the center conductors 514 and 614 or noise may be emitted from the center conductors 514 and 614. In more detail, as shown in FIG. 17, in the coaxial connector socket 600, the lower end portion of the right side of the outer conductor 612 does not reach the lower end of the coaxial connector socket 600. Therefore, when viewed from the upper side, the insulator 616 is wound from the inside surrounded by the outer conductor 612 to the outside surrounded by the outer conductor 612. Therefore, the insulator 616 contacts the outer conductor 612 from the lower side. As a result, when the insulator 616 receives an upward force, the insulator 616 is caught on the outer conductor 612. Therefore, the insulator 616 can be prevented from being easily detached from the outer conductor 612.

However, a gap G where no external conductor 612 exists is formed between the lower end of the right side portion of the external conductor 612 and the lower surface of the coaxial connector socket 600. Such a gap G may be an intrusion path for noise to enter the center conductors 514 and 614 from outside the coaxial connector plug 500 and the coaxial connector socket 600, or to radiate noise from the center conductors 514 and 614 to the coaxial connection. The radiation path of noise outside the connector plug 500 and the coaxial connector socket 600 may be at risk.

Therefore, an object of the present invention is to provide a connector, a connector group, and a method for manufacturing a connector that can suppress the intrusion or radiation of noise.

(Composition of male connector)

First, the male connector will be described with reference to the drawings. FIG. 1 is an external perspective view of the male connector 110 when viewed from the upper side. FIG. 2 is an external perspective view of the male connector 110 when viewed from the lower side. FIG. 3 is a sectional structural view of the male connector 110 along A-A in FIG. 1. FIG. 4 is a sectional structural view of the male connector 110 along B-B in FIG. 1.

Hereinafter, the normal direction of the upper surface Sa of the planar portion 112b of the ground conductor 112 is defined as the vertical direction. In addition, the direction in which the center conductor 114 and the center conductor 115 are aligned when viewed from the upper side is defined as the front-rear direction. A direction orthogonal to the up-down direction and the front-back direction is defined as a left-right direction. The up-down direction, the front-back direction, and the left-right direction are orthogonal to each other. However, the up-down direction, the front-back direction, and the left-right direction are directions defined for the sake of explanation, and may not be consistent with the up-down direction, the front-back direction, and the left-right direction when the male connector 110 is actually used.

The male connector 110 (an example of a first connector and a connector) is mounted on a circuit board such as a flexible printed circuit board, and includes a ground conductor 112, center conductors 114 and 115, and an insulator 116 as shown in FIGS.

The ground conductor 112 (an example of the first ground conductor) is manufactured by subjecting a piece of metal plate (for example, phosphor bronze) having conductivity and elasticity to a stamping process and a bending process. Furthermore, the ground conductor 112 is subjected to nickel plating and silver plating. As shown in FIGS. 1 to 4, the ground conductor 112 includes an outer conductor 112 a, a planar portion 112 b, support portions 112 c, 112 d, 112 f, and 112 g, and lock portions 112 e and 112 h.

The outer conductor 112a (an example of the first outer conductor) has a cylindrical shape having an imaginary central axis Ax1 (an example of the first central axis) extending in the up-down direction (an example of the first direction). When viewed from the upper side, the outer conductor 112a has an elliptical shape with the longitudinal direction as the longitudinal direction. The outer conductor 112a has an elliptical cross-sectional shape at any position in the vertical direction. The cross-sectional shape refers to the shape of a cross section orthogonal to the vertical direction. Accordingly, the outer conductor 112a is not provided with a cutout or a hole that communicates the inside of the outer conductor 112a with the outside, except for the openings on the upper side and the lower side. The central axis Ax1 is a line obtained by connecting the center of gravity of a cross section orthogonal to the vertical direction in the outer conductor 112a. However, the central axis Ax1 cannot be recognized because it is an imaginary axis.

The planar portion 112b is a plate-like member connected to the lower end of the outer conductor 112a (an example of an end portion on one side in the first direction) and having an upper surface Sa and a lower surface Sb orthogonal to the vertical direction. The upper surface Sa and the lower surface Sb are rectangular. The long sides of the upper surface Sa and the lower surface Sb extend in the front-rear direction. The short sides of the upper surface Sa and the lower surface Sb extend in the left-right direction. When viewed from the upper side, the centers of the upper surface Sa and the lower surface Sb (the intersections of the diagonals) coincide with the central axis Ax1 of the outer conductor 112a. The outer conductor 112a has a structure protruding from the flat portion 112b toward the upper side.

Here, the boundary between the outer conductor 112a and the planar portion 112b will be described with reference to the enlarged view of FIG. 3. The ground conductor 112 is manufactured by subjecting a single metal plate to a pressing process and a bending process. It is difficult to bend the metal plate into a right angle during the bending process. Therefore, the vicinity of the lower end of the outer conductor 112a is gently curved so as to move away from the central axis Ax1 as it goes downward. The bent portion of the ground conductor 112 is a portion of the outer conductor 112a, and is not a portion of the flat portion 112b. The flat portion 112b is a portion of the ground conductor 112 that is not bent and is parallel to the front-rear direction and the left-right direction. Therefore, the height above and below the lower end of the outer conductor 112a coincides with the height above and below the lower surface Sb of the flat portion 112b.

The support portions 112c and 112d are connected to the planar portion 112b and are arranged at intervals in the front-rear direction. The support portion 112c is formed by bending a belt-like member extending from the vicinity of the rear end of the long side on the right side of the flat portion 112b toward the right side. The support portion 112c includes a connection portion 122c and a tip portion 124c. The connecting portion 122c is bent at a right angle with respect to the flat portion 112b, and extends from the flat portion 112b toward the upper side. The end portion 124c is bent from the upper end of the connecting portion 122c to the right side, and extends from the upper end of the connecting portion 122c toward the lower side. Thereby, the support portion 112c is U-shaped turned upside down when viewed from the front-rear direction. The support portion 112c having such a structure can be elastically deformed in such a manner that the interval between the connection portion 122c and the end portion 124c is changed (especially widened).

The support portion 112d is formed by bending a belt-shaped member extending from the vicinity of the front end of the long side on the right side of the flat portion 112b toward the right side. The support portion 112d includes a connection portion 122d and a tip portion 124d. Since the structures of the connection portion 122d and the end portion 124d are the same as the structures of the connection portion 122c and the end portion 124c, description thereof is omitted.

The lock portion 112e is a leaf spring formed by bending a part of the ground conductor 112, and is connected to the support portions 112c and 112d. More specifically, the lock portion 112e is located between the support portion 112c and the support portion 112d in the front-back direction, and includes a connection portion 126e, a middle portion 128e, and a tip portion 130e. The connection portion 126e has a band shape extending in the front-rear direction. The rear end of the connection portion 126e is connected to the end portion 124c of the support portion 112c. The front end of the connection portion 126e is connected to the end portion 124d of the support portion 112d.

Further, the lock portion 112e extends upward from the portions connected to the support portions 112c and 112d, and extends toward the lower side by being bent to the left (that is, the direction approaching the outer conductor 112a). In this embodiment, the intermediate portion 128e is connected to the upper end of the connection portion 126e, and extends from the upper end of the connection portion 126e toward the lower left side. Further, the tip portion 130e is connected to the lower end of the intermediate portion 128e, and extends from the lower end of the intermediate portion 128e toward the lower right side. The lower end of the tip portion 130e is not connected to another structure. The lock portion 112e having such a structure can be elastically deformed such that an angle formed by the middle portion 128e and the tip portion 130e moves to the left and right (especially the right side).

The support portions 112f and 112g are connected to the flat portion 112b and are arranged at intervals in the front-rear direction. Among them, the structures of the support portions 112f and 112g are symmetrical to the structure planes of the support portions 112c and 112d with respect to a plane passing through a diagonal line of the upper surface Sa of the plane portion 112b and perpendicular to the left-right direction. Therefore, detailed descriptions of the support sections 112f and 112g are omitted.

The locking portion 112h is a leaf spring formed by bending a part of the ground conductor 112, and is connected to the support portions 112f and 112g. Among them, the structure of the lock portion 112h is symmetrical to the structure plane of the lock portion 112e with respect to a plane passing through a diagonal line of the upper surface Sa of the flat portion 112b and perpendicular to the left-right direction. Therefore, detailed description of the lock portion 112h is omitted.

The center conductors 114 and 115 (an example of the first center conductor) are produced by subjecting a single metal plate (for example, phosphor bronze) to press working and bending. Furthermore, the center conductors 114 and 115 are plated with nickel and silver. As shown in FIG. 1 to FIG. 4, the center conductor 114 and the center conductor 115 are arranged in order from the rear side to the front side in an area surrounded by the outer conductor 112 a when viewed from the upper side.

The center conductor 114 includes a connection portion 114a and a mounting portion 114b. The connection portion 114a has a cylindrical shape having a central axis extending in the vertical direction. However, the upper end of the connection portion 114a is not opened. The mounting portion 114b is connected to the lower end of the connection portion 114a, and extends from the lower end of the connection portion 114a toward the lower side. As shown in Fig. 2, the lower end of the mounting portion 114b is positioned at the same height as the lower surface Sb in the vertical direction.

The center conductor 115 includes a connection portion 115a and a mounting portion 115b. However, since the structure of the center conductor 115 is the same as the structure of the center conductor 114, the description is omitted.

The insulator 116 (an example of the first insulator) is provided in an area surrounded by the outer conductor 112 a when viewed from above, and fixes the relative positions of the center conductors 114 and 115 and the outer conductor 112 a. However, the insulator 116 may also exist outside the area surrounded by the outer conductor 112a. The insulator 116 includes detachment prevention portions 116 a and 116 c and a main body portion 116 b. The main body portion 116b covers the entire inner peripheral surface of the outer conductor 112a and covers substantially the entire opening on the lower side of the outer conductor 112a. Among them, as shown in FIG. 2, through holes H1 and H2 penetrating the main body portion 116 b in the up-down direction are provided on the left side of each of the center conductors 114 and 115. The through holes H1 and H2 are located in a region surrounded by the outer conductor 112a when viewed from the upper side.

The lower half of the connecting portions 114a and 115a and the mounting portions 114b and 115b are fitted into the main body portion 116b. Thereby, the center conductors 114 and 115 are fixed to the insulator 116. As shown in FIG. 2, the lower ends of the mounting portions 114 b and 115 b (an example of one side in the first direction) are exposed from the main body portion 116 b.

As shown in the enlarged view of FIG. 3, the detachment preventing portion 116 a is a portion of the insulator 116 located directly above the upper end of the outer conductor 112 a. Thereby, the detachment prevention part 116a contacts the upper surface F1 (an example of a 2nd surface) in the outer conductor 112a. The surface F1 is provided at the upper end in the outer conductor 112a.

As shown in the enlarged view of FIG. 3, the detachment preventing portion 116 c is the nearest portion of the insulator 116 located below a portion that is gently curved near the lower end of the outer conductor 112 a. Thereby, the detachment prevention part 116c contacts the lower surface F2 (an example of a 1st surface) in the outer conductor 112a. The surface F2 is provided at the lower end in the outer conductor 112a. As shown in Fig. 2, the detachment prevention portion 116c has an elliptical ring when viewed from the lower side, and surrounds the periphery of the main body portion 116b. Further, the body portion 116b and the detachment prevention portion 116c form a flat surface (the lower surface of the insulator 116). Further, the lower surface and the lower surface Sb of the insulator 116 form a flat surface.

Here, the positional relationship between the ground conductor 112 and the lower ends of the center conductors 114 and 115 (the lower ends of the mounting portions 114b and 115b) will be described. The height in the up-down direction of the lower surface of the insulator 116 coincides with the height in the up-down direction of the lower surface Sb. Therefore, the lower surface of the insulator 116 and the lower surface Sb form a plane. As shown in FIG. 2, lower ends of the center conductors 114 and 115 (ie, lower ends of the mounting portions 114 b and 115 b) are exposed from the lower surface of the insulator 116. Therefore, the plane S20 passing through the lower ends of the center conductors 114 and 115 and orthogonal to the up-down direction coincides with the plane formed by the lower surface and the lower surface Sb of the insulator 116. Thereby, the ground conductor 112 (planar portion 112b) surrounds the lower ends of the center conductors 114 and 115 in the plane S20. That is, the lower ends of the center conductors 114 and 115 do not protrude to the lower side than the ground conductor 112.

(Composition of female connector)

Next, the female connector will be described with reference to the drawings. FIG. 5 is an external perspective view of the female connector 10 when viewed from the lower side. FIG. 6 is an external perspective view of the female connector 10 when viewed from the upper side. FIG. 7 is a sectional structural view along the female connector 10 of C-C in FIG. 5. FIG. 8 is a cross-sectional structure view of the female connector 10 along D-D in FIG. 5.

Hereinafter, the normal direction of the flat portion 12b of the ground conductor 12 is defined as the vertical direction. The direction in which the center conductor 14 and the center conductor 15 are aligned when viewed from the lower side is defined as the front-rear direction. A direction orthogonal to the up-down direction and the front-back direction is defined as a left-right direction. The up-down direction, the front-back direction, and the left-right direction are orthogonal to each other. However, the up-down direction, the front-back direction, and the left-right direction are directions defined for the sake of explanation, and may not be the same as the up-down direction, front-back direction, and left-right direction when the female connector 10 is actually used.

The female connector 10 (an example of the second connector) is mounted on a circuit board such as a flexible printed circuit board, and includes a ground conductor 12, a center conductor 14, 15 and an insulator 16 as shown in FIGS. 5 to 8.

The ground conductor 12 (an example of the second ground conductor) is produced by performing a stamping process and a bending process on a metal plate (for example, phosphor bronze) having conductivity and elasticity. Furthermore, the ground conductor 12 is plated with nickel and silver. As shown in FIGS. 5 to 8, the ground conductor 12 includes an outer conductor 12 a, a planar portion 12 b, support portions 12 c and 12 d, and lock portions 12 e and 12 f.

The outer conductor 12a (an example of a second outer conductor) has a cylindrical shape having an imaginary central axis Ax2 (an example of a second central axis) extending in the vertical direction. When viewed from the lower side, the outer conductor 12a has an elliptical shape with the longitudinal direction as the longitudinal direction. The outer conductor 12a has an elliptical cross-sectional shape at any position in the vertical direction. Thereby, the outer conductor 12a is not provided with a cutout or a hole that communicates the inside with the outside, except for the openings on the upper side and the lower side. As shown in FIG. 7, the upper end of the outer conductor 12a is bent in a direction close to the central axis Ax2.

The flat portion 12b is a plate-shaped member connected to the lower end of the outer conductor 12a and having a lower surface Sc and an upper surface Sd orthogonal to the vertical direction. The lower surface Sc and the upper surface Sd are rectangular. The long sides of the lower surface Sc and the upper surface Sd extend in the front-rear direction. The short sides of the lower surface Sc and the upper surface Sd extend in the left-right direction. When viewed from the lower side, the centers of the lower surface Sc and the upper surface Sd (the intersections of the diagonals) coincide with the central axis Ax2 of the outer conductor 12a. The outer conductor 12a has a structure that protrudes upward from the flat portion 12b.

Here, the boundary between the outer conductor 12a and the flat portion 12b will be described with reference to the enlarged view of FIG. 7. The ground conductor 12 is manufactured by subjecting a single metal plate to a pressing process and a bending process. It is difficult to bend the metal plate into a right angle during the bending process. Therefore, the vicinity of the lower end of the outer conductor 12a is gently curved so as to move away from the central axis Ax2 as it goes downward. The bent portion of the ground conductor 12 is a portion of the outer conductor 12a, and is not a portion of the planar portion 12b. The flat portion 12 b is a portion of the ground conductor 12 that is not bent and is parallel to the front-rear direction and the left-right direction. Therefore, the height above and below the lower end of the outer conductor 12a coincides with the height above and below the lower surface Sc of the planar portion 12b.

The support portions 12c and 12d are connected to the flat portion 12b. The support portion 12c is formed by bending a rectangular-shaped member extending from the right side to the right side of the flat portion 12b. The support portion 12c includes a side surface portion 22c and a mounting portion 24c. The side portion 22c is bent from the flat portion 12b at a right angle, and extends from the flat portion 12b toward the upper side. The mounting portion 24c is bent at a right angle with respect to the side portion 22c, and extends from the upper end of the side portion 22c to the left. Thereby, the support part 12c is L-shaped when seen from the front side.

However, an opening H20 is provided in the side surface portion 22c (see FIG. 7). The opening H20 has a rectangular shape with long sides extending in the front-back direction when viewed from the right side. The opening H20 is provided in a region in the lower half of the side portion 22c. Thereby, the side surface portion 22c is connected to the plane portion 12b only near the front end and the rear end of the long side on the right side of the plane portion 12b.

The support portion 12d is formed by bending a rectangular-shaped member extending from the left side to the left of the flat portion 12b. The support portion 12d includes a side portion 22d and a mounting portion 24d. Among them, the structures of the side surface portion 22d and the mounting portion 24d are symmetrical to the structure surfaces of the side surface portion 22c and the mounting portion 24c with respect to a plane passing through the intersection of diagonal lines of the lower surface Sc of the plane portion 12b and perpendicular to the left and right directions. Therefore, detailed descriptions of the side portions 22d and the mounting portions 24d are omitted.

The lock portion 12e is connected to the flat portion 12b. More specifically, the locking portion 12e is a protrusion slightly protruding from the long side on the right side of the flat portion 12b to the right side. The locking portion 12e has an isosceles ladder shape when viewed from the upper side. The bottom of the locking portion 12e coincides with the long side to the right of the flat portion 12b. The lock portion 12e is provided at a position overlapping the opening H20 in the front-rear direction.

The lock portion 12f is connected to the flat portion 12b. Among them, the structure of the lock portion 12f is symmetrical to the structure of the lock portion 12e with respect to a plane passing through the intersection of diagonal lines of the lower surface Sc of the flat portion 12b and perpendicular to the left-right direction. Therefore, detailed descriptions of the side portions 22d and the mounting portions 24d are omitted.

The center conductors 14 and 15 (an example of the second center conductor) are manufactured by subjecting a single metal plate (for example, phosphor bronze) to press working and bending. Furthermore, the center conductors 14 and 15 are plated with nickel and silver. As shown in FIG. 5 to FIG. 8, the center conductor 14 and the center conductor 15 are arranged in order from the rear side to the front side in an area surrounded by the outer conductor 12 a when viewed from the lower side.

The center conductor 14 includes a connection portion 14a and a mounting portion 14b. The connection portion 14a has a cylindrical shape having a central axis extending in the vertical direction. The lower end of the connection portion 14a is open. Further, three slits S1 to S3 extending in the vertical direction are provided in the connecting portion 14a. Thereby, the connection part 14a can be elastically deformed so that the diameter of the connection part 14a changes (especially widens) when viewed from the lower side.

The mounting portion 14b is connected to the upper end of the connection portion 14a, and extends from the upper end of the connection portion 14a toward the upper side. As shown in FIGS. 6 and 8, the upper end of the mounting portion 14 b is positioned at the same height as the upper end of the outer conductor 12 a in the vertical direction.

The center conductor 15 includes a connection portion 15a and a mounting portion 15b. However, since the structure of the center conductor 15 is the same as the structure of the center conductor 14, the description is omitted.

The insulator 16 (an example of the second insulator) is disposed in an area surrounded by the outer conductor 12 a when viewed from below, and fixes the relative positions of the center conductors 14 and 15 and the outer conductor 12 a. However, the insulator 16 may also be provided outside the area surrounded by the outer conductor 12a. The insulator 16 includes detachment prevention portions 16 a and 16 c and a main body portion 16 b. The main body portion 16b covers the entire inner peripheral surface of the outer conductor 12a, and covers substantially the entire opening on the upper side of the outer conductor 12a. However, as shown in FIG. 6, a through hole H3 is provided on the left side of the center conductors 14 and 15 and penetrates the main body portion 16 b in the vertical direction. The through hole H3 is located in a region surrounded by the outer conductor 12a when viewed from the lower side.

The mounting portions 14b and 15b are fitted into the main body portion 16b. Thereby, the center conductors 14 and 15 are fixed to the insulator 16. As shown in FIG. 8, the upper ends of the mounting portions 14 b and 15 b (an example of the other side in the first direction) are exposed from the main body portion 16 b.

As shown in the enlarged view of FIG. 7, the detachment preventing portion 16 a is a portion of the insulator 16 closest to a portion that is gently curved near the lower end of the outer conductor 12 a. Thereby, the detachment prevention part 16a contacts the lower surface F3 in the outer conductor 12a.

As shown in the enlarged view of FIG. 7, the detachment preventing portion 16 c is a portion of the insulator 16 that is in contact with the bent portion of the outer conductor 12 a from the upper side. More specifically, the upper end of the outer conductor 12a is bent so as to approach the central axis of the outer conductor 12a. Then, the corners of the ends of the bent portions of the outer conductor 12a are chamfered. As a result, a surface F4 facing the oblique upper side is formed at an end of a portion where the outer conductor 12a is bent. The detachment preventing portion 16c is in contact with the surface F4 formed by the chamfering, and is a portion of the insulator 16 located on the upper side than the surface F4.

As shown in FIG. 6, the detachment prevention portion 16 c has an elliptical ring shape when viewed from below, and surrounds the periphery of the main body portion 16 b. Further, the body portion 16b and the detachment prevention portion 16c form a flat surface (ie, the upper surface of the insulator 16). Furthermore, a flat surface is formed on the upper surface of the insulator 16 and the upper end of the outer conductor 12a.

Here, the positional relationship between the ground conductor 12 and the upper ends of the center conductors 14 and 15 (upper ends of the mounting portions 14b and 15b) will be described. The height in the up-down direction of the upper surface of the insulator 16 coincides with the height in the up-down direction of the upper end of the outer conductor 12a. Therefore, the upper surface of the insulator 16 and the upper end of the outer conductor 12a form a plane. As shown in FIG. 6, the upper ends of the center conductors 14 and 15 (that is, the upper ends of the mounting portions 14 b and 15 b) are exposed from the upper surface of the insulator 16. Therefore, the plane S22 passing through the upper ends of the center conductors 14 and 15 and orthogonal to the up-down direction is consistent with the plane formed by the upper surface of the insulator 16 and the upper end of the outer conductor 12a. Therefore, the ground conductor 12 (outer conductor 12a) is located in the plane S22 and surrounds the upper ends of the center conductors 14 and 15. That is, the upper ends of the center conductors 14 and 15 do not protrude to the upper side than the ground conductor 12.

(Connection between male connector and female connector)

Hereinafter, the connection between the male connector 110 and the female connector 10 will be described with reference to the drawings. FIG. 9 is a diagram showing a circuit board 200 to which the male connector 110 is mounted. FIG. 10 is a diagram showing a circuit board 220 on which the female connector 10 is mounted. In FIG. 9 and FIG. 10, the areas for installing the male connector 110 and the female connector 10 are enlarged and shown. FIG. 11 is a cross-sectional structure view of the connector group 1 formed by connecting the male connector 110 and the female connector 10.

The circuit board 200 shown in FIG. 9 includes a substrate body 201 and pad electrodes 202, 204, and 206. The substrate body 201 is a flat plate-shaped member, and has an upper surface and a lower surface. The pad electrode 202 is disposed on the upper surface of the substrate body 201 and has a shape consistent with the lower surface Sb of the planar portion 112b when viewed from the upper side. That is, the pad electrode 202 has a rectangular outer edge. However, in the vicinity of the center of the pad electrode 202, an elliptical region without a conductor is provided. In addition, the pad electrodes 204 and 206 are provided so as to be sequentially arranged from the rear side to the front side in the elliptical region, respectively. That is, the pad electrodes 204 and 206 are provided at positions corresponding to the lower ends of the mounting portions 114b and 115b, respectively.

When the male connector 110 is mounted on the circuit substrate 200, solder paste is applied to the pad electrodes 202, 204, and 206. Then, the lower surface Sb is connected to the pad electrode 202 and the lower ends of the mounting portions 114b and 115b are connected to the pad electrodes 204 and 206. The male connector 110 is provided on the upper surface of the circuit substrate 200. Then, after the solder is melted by the heating step, the solder is solidified by the cooling step. Thereby, the male connector 110 is mounted on the circuit substrate 200.

The circuit board 220 shown in FIG. 10 includes a substrate body 221 and pad electrodes 222, 224, and 226. The substrate body 221 is a flat plate-shaped member, and has an upper surface and a lower surface. The pad electrode 222 is provided on the lower surface of the substrate body 221 and has a shape substantially consistent with the mounting portions 24c and 24d when viewed from the lower side. However, the pad electrodes 222 are not separated into two like the mounting portions 24c and 24d, but have a rectangular shape connected to one. In the vicinity of the center of the pad electrode 222, an elliptical region without a conductor is provided. The pad electrodes 224 and 226 are arranged in order from the rear side to the front side in the elliptical region, respectively. That is, the pad electrodes 224 and 226 are provided at positions corresponding to the upper ends of the mounting portions 14b and 15b, respectively.

When the female connector 10 is mounted on the circuit board 220, solder is applied to the pad electrodes 222, 224, and 226. Then, the female connector 10 is disposed on the lower surface of the circuit board 220 such that the mounting portions 24c and 24d are connected to the pad electrodes 222 and the upper ends of the mounting portions 14b and 15b are connected to the pad electrodes 224 and 226. Then, after the solder is melted by the heating step, the solder is solidified by the cooling step. Thereby, the female connector 10 is mounted on the circuit board 220.

The male connector 110 and the female connector 10 mounted to the circuit substrates 200 and 220 as described above are connected as shown in FIG. 11 in such a manner that the male connector 110 is located at a lower side than the female connector 10. That is, the male connector 110 is connected to the female connector 10 from the lower side. In other words, the female connector 10 is connected such that it is located on the upper side than the male connector 110. That is, the female connector 10 is connected to the male connector 110 from the upper side. At this time, the outer conductor 112a is inserted into the outer conductor 12a from the lower side. However, the inner peripheral surface of the outer conductor 12 a is covered with the insulator 16. Therefore, the outer peripheral surface of the outer conductor 112a contacts the insulator 16 and does not contact the inner peripheral surface of the outer conductor 12a. Thereby, positioning of the male connector 110 and the female connector 10 in the front-back direction and the left-right direction is completed.

When the male connector 110 is connected to the female connector 10, the connection portion 114a is inserted into the connection portion 14a from the lower side. Thereby, the connection portion 14a and the connection portion 114a are electrically connected.

When the outer conductor 112a enters the outer conductor 12a from the lower side, the lock portions 12e and 12f contact the lock portions 112e and 112h (more precisely, the middle portions 128e and 128h) from the upper side, respectively. When the outer conductor 112a rises, the lock portion 12e pushes the lock portion 112e to the right, and the lock portion 12f pushes the lock portion 112h to the left. Thereby, in FIG. 11, the lock portions 112 e and 112 h are elastically deformed, and the interval between the lock portion 112 e and the lock portion 112 h is widened. Furthermore, when the outer conductor 112a rises, the lock portion 12e is folded under the connection portion through the connection portion (ie, the corner of the lock portion 112e) of the middle portion 128e and the end portion 130e, and the lock portion 12f passes through the middle The connecting portion of 128h and the end portion 130h (that is, the corner of the locking portion 112h) is folded into the lower side of the connecting portion. Thereby, the lock parts 112e and 112h want to return to the original state, respectively, and the tip parts 130e and 130h contact the lock parts 12e and 12f. The tip portion 130e has a surface facing the lower left side, and the tip portion 130h has a surface facing the lower right side. Thereby, the tip parts 130e and 130h push the lock parts 12e and 12f downward, respectively. At this time, by the reaction, the lock portions 12e and 12f push the lock portions 112e and 112h upward, respectively. In this way, the locking portions 112e and 112h are elastic bodies that push the female connector 10 downward by elastic deformation. The upper surface Sa of the planar portion 112b is in surface contact with the lower surface Sc of the planar portion 12b. The upper surface Sa surrounds the outer conductor 112a when viewed from the upper side. The lower surface Sc surrounds the outer conductor 12a when viewed from the upper side. Therefore, the upper surface Sa (the flat portion 112b) and the lower surface Sc (the flat portion 12b) are in contact with each other so as to surround the outer conductors 112a and 12a when viewed from the upper side. Thereby, the ground conductor 12 and the ground conductor 112 are electrically connected.

In the connector group 1 as described above, high-frequency signals are applied to the center conductors 14, 15, 114, and 115. The high-frequency signals applied to the center conductors 14, 114 and the high-frequency signals applied to the center conductors 15, 115 are, for example, differential transmission signals. The ground conductors 12 and 112 are held at a ground potential.

(Manufacturing method of male connector and female connector)

Hereinafter, a method of manufacturing the male connector 110 and the female connector 10 will be described. Since the manufacturing method of the male connector 110 is substantially the same as the manufacturing method of the female connector 10, the manufacturing method of the male connector 110 is described, and the manufacturing method of the female connector 10 is omitted.

First, a stamping process and a bending process are performed on a phosphor bronze metal plate to produce a ground conductor 112 shown in FIG. 1. However, as long as the metal plate has conductivity and elasticity, a metal plate other than phosphor bronze may be used.

Next, stamping and bending are performed on the phosphor bronze metal plate to produce the center conductors 114 and 115 and the ground conductor 112 shown in FIG. 1. However, as long as the metal plate has conductivity and elasticity, a metal plate other than phosphor bronze may be used.

Next, the ground conductor 112, the center conductors 114, 115, and the resin-based insulator 116 are integrated by insert molding. More specifically, the ground conductor 112 and the center conductors 114 and 115 are set in a mold, and a molten resin (for example, a liquid crystal polymer) is injected into the mold. Then, the resin is cooled and solidified. Through the above steps, the male connector 110 is completed.

Furthermore, after the ground conductor 112 and the insulator 116 made of resin are integrated by insert molding, the center conductors 114 and 115 may be pressed into the insulator 116. Alternatively, the center conductors 114 and 115 and the insulator 116 made of resin may be integrated by insert molding, and then the ground conductor 112 may be pressed into the insulator 116.

(Effect)

According to the male connector 110, the female connector 10, and the connector group 1 configured as described above, intrusion or radiation of noise can be suppressed. More specifically, in the male connector 110, the ground conductor 112 (the flat portion 112 b) surrounds the lower ends of the center conductors 114 and 115 in the plane S20. The plane S20 is a plane passing through the lower ends of the center conductors 114 and 115 and orthogonal to the vertical direction. Accordingly, the lower ends of the center conductors 114 and 115 do not protrude to the lower side than the ground conductor 112. Therefore, when the male connector 110 is mounted on the circuit board 200, the lower ends of the center conductors 114 and 115 are covered by the outer conductor 112a when viewed from the front-rear direction and the left-right direction. As a result, it is possible to suppress noise from entering the vicinity of the lower ends of the center conductors 114 and 115 or radiating noise from the vicinity of the lower ends of the center conductors 114 and 115. In the female connector 10, the ground conductor 12 (the flat portion 12b) surrounds the upper ends of the center conductors 14, 15 in the plane S22. The plane S22 is a plane passing through the upper ends of the center conductors 14 and 15 and orthogonal to the vertical direction. Therefore, according to the female connector 10, for the same reason as the male connector 110, the intrusion or radiation of noise can be suppressed.

In addition, the male connector 110, the female connector 10, and the connector group 1 can suppress the intrusion or radiation of noise for the following reasons. More specifically, the outer conductors 112a and 12a are cylindrical, and the outer conductor 112a is inserted into the outer conductor 12a. In this case, the space Sp (refer to FIG. 11) between the inner peripheral surface of the outer conductor 12a and the outer peripheral surface of the outer conductor 112a and the space where the center conductors 114, 115, 14, and 15 are provided ( Space) is not interrupted by the conductor and communicates. Therefore, if there are multiple paths of noise that connect the space Sp with the space outside the outer conductor 12a, the noise enters the center conductors 114, 115, 14, 15 from outside the outer conductor 12a through the above path and space Sp. Fear. Similarly, noise may radiate from the center conductors 114, 115, 14, and 15 to the outside of the outer conductor 12a via the space Sp and the above-mentioned path. Therefore, when the male connector 110, the female connector 10, and the connector group 1 are connected to the female connector 10, the flat portion 112b and the flat portion 12b surround the outside when viewed from the upper side. The conductors 112a and 12a are in contact with each other. Thereby, the number of paths of noise that connect the space Sp with the space outside the outer conductor 12a can be reduced. As a result, according to the male connector 110, the female connector 10, and the connector group 1, intrusion or radiation of noise can be suppressed.

According to the male connector 110, the female connector 10, and the connector group 1, the male connector 110 and the female connector 10 are fixed. More specifically, the external conductor 512 described in Patent Document 1 holds the external conductor 612 by being elastically deformed. On the other hand, the outer conductor 12a is not elastically deformed, so the outer conductor 112a is not held. The outer conductors 12a and 112a only position the male connector 110 and the female connector 10 in the front-rear direction and the left-right direction by inserting the outer conductor 112a into the outer conductor 12a. Therefore, the male connector 110 includes locking portions 112e and 112h. When the male connector 110 and the female connector 10 are connected, the locking portions 12e and 12f of the female connector 10 are pushed downward. . Thereby, the female connector 10 is pressed against the male connector 110, the positioning of the male connector 110 and the female connector 10 in the up-down direction is completed, and the male connector 110 and the female connector 10 are fixed.

As described above, according to the male connector 110, the female connector 10, and the connector group 1, in order to suppress the intrusion and radiation of noise, the outer conductors 12a and 112a are not elastically deformed. That is, the outer conductors 12a and 112a are not provided with a lock function. On the other hand, the male connector 110 includes locking portions 112e and 112h that press the locking portions 12e and 12f of the female connector 10 downward. That is, the male connector 110 and the female connector 10 have a locking function in a portion different from the outer conductors 12a and 112a. Therefore, according to the male connector 110, the female connector 10, and the connector group 1, it is possible to take into account the difficulty of the intrusion or radiation suppression of the previously difficult noise and the fixing of the male connector 110 and the female connector 10.

In addition, the male connector 110, the female connector 10, and the connector group 1 can more effectively suppress the intrusion and radiation of noise for the following reasons. More specifically, the planar portion 112b has an upper surface Sa. The planar portion 12b has a lower surface Sc. When the male connector 110 and the female connector 10 are connected, the upper surface Sa is in surface contact with the lower surface Sc. Thereby, the path of noise formation between the upper surface Sa and the lower surface Sc can be more effectively suppressed, and the intrusion and radiation of the noise can be more effectively suppressed.

In addition, the male connector 110, the female connector 10, and the connector group 1 can easily connect the male connector 110 and the female connector 10. More specifically, the lock portion 112e extends upward from a portion connected to the support portions 112c and 112d, and extends toward the lower side by being bent toward a direction (left side) approaching the outer conductor 112a. The lock portion 112h extends upward from the portions connected to the support portions 112f and 112g, and extends toward the lower side by being bent in a direction (right side) approaching the outer conductor 112a. Thereby, the distal ends of the lock portions 112e and 112h face downward. Therefore, when the male connector 110 is connected from the lower side of the female connector 10, the ends of the locking portions 112 e and 112 h can be prevented from being caught on the female connector 10. As a result, according to the male connector 110, the female connector 10, and the connector group 1, the connection between the male connector 110 and the female connector 10 can be easily performed. In addition, the strength of the fixing of the male connector 110 and the female connector 10 can be adjusted by adjusting the angle formed by the connecting portion 126e and the intermediate portion 128e and the angle formed by the connecting portion 126h and the intermediate portion 128h.

The male connector 110 and the female connector 10 and the connector group 1 firmly fix the male connector 110 and the female connector 10. More specifically, the lock portion 112e is pushed to the lower left side by the lock portion 12e, and is pushed to the upper right side by the reaction. When the lock portion 112e is displaced to the right by this reaction, the force with which the lock portion 112e presses the lock portion 12e becomes small. Therefore, the lock portion 112e is located between the support portion 112c and the support portion 112d, and is connected to the support portion 112c and the support portion 112d. Thereby, the lock part 112e is supported from the front and back sides. As a result, the lock portion 112e is suppressed from being displaced to the right due to the reaction. Therefore, the locking portion 112e presses the locking portion 12e with a sufficient force to firmly fix the male connector 110 and the female connector 10. The lock portion 112h may be the same as the lock portion 112e.

In addition, the male connector 110, the female connector 10, and the connector group 1 prevent the insulator 116 from detaching from the ground conductor 112 to the upper side. More specifically, as shown in the enlarged view of FIG. 3, the insulator 116 is in contact with the lower surface F2 of the outer conductor 112 a. Thereby, even if the insulator 116 receives an upward force, it will be stuck on the surface F2. As a result, the insulator 116 can be prevented from detaching from the ground conductor 112 to the upper side.

In addition, the male connector 110, the female connector 10, and the connector group 1 prevent the insulator 116 from coming off from the ground conductor 112 to the lower side. More specifically, as shown in the enlarged view of FIG. 3, the insulator 116 is in contact with the upper surface F1 of the outer conductor 112 a. As a result, the insulator 116 is caught on the surface F1 even if it is subjected to a downward force. As a result, detachment of the insulator 116 from the ground conductor 112 to the lower side can be suppressed.

In addition, the male connector 110, the female connector 10, and the connector group 1 prevent the insulator 16 from detaching from the ground conductor 12 to the upper side. More specifically, as shown in an enlarged view of FIG. 7, the insulator 16 is in contact with the lower surface F3 of the outer conductor 12 a. Thereby, even if the insulator 16 receives an upward force, it will be stuck on the surface F3. As a result, the insulator 116 can be prevented from detaching from the ground conductor 112 to the upper side.

In addition, the male connector 110, the female connector 10, and the connector group 1 prevent the insulator 16 from detaching from the ground conductor 12 to the lower side. More specifically, as shown in the enlarged view of FIG. 7, the insulator 16 is in contact with the upper surface F4 of the outer conductor 12 a. Thereby, even if the insulator 16 receives a downward force, it will be stuck on the surface F4. As a result, detachment of the insulator 16 from the ground conductor 12 to the lower side can be suppressed.

On the left side of each of the center conductors 114 and 115, through-holes H1 and H2 penetrating the main body portion 116b in the vertical direction are provided. Therefore, the center conductors 114 and 115 are soldered to the pad electrodes 204 and 206 through the through holes H1 and H2. In addition, by providing the through holes H1 and H2, it is possible to suppress the flux from spreading upward.

A through hole H3 is provided on the left side of each of the center conductors 14 and 15 and penetrates the main body portion 16b in the vertical direction. Therefore, the center conductors 14 and 15 are soldered to the pad electrodes 224 and 226 through the through-hole H3. Moreover, by providing the through-hole H3, it is also possible to suppress the spread of the flux.

In addition, according to the male connector 110, the female connector 10, and the connector group 1, it is possible to accurately position the male connector 110 and the female connector 10 in the front-back direction and the left-right direction. Hereinafter, a connector group in which the outer peripheral surface of the outer conductor 712 corresponding to the outer conductor 112a and the inner peripheral surface of the outer conductor 612 corresponding to the outer conductor 12a are in direct contact will be described as a connector group of a reference example. The connector group of the reference example is an example of the connector group of the present invention.

The outer conductors 612 and 712 are manufactured by bending a metal plate or the like. Since the processing accuracy of such outer conductors 612 and 712 is relatively low, it is difficult to closely contact the outer peripheral surface of the outer conductor 712 and the inner peripheral surface of the outer conductor 612.

On the other hand, in the female connector 10, the insulator 16 covers the inner peripheral surface of the outer conductor 12a. The outer conductor 112a is inserted into the outer conductor 12a. Therefore, the insulator 16 contacts the outer peripheral surface of the outer conductor 112a. The insulator 16 is produced by, for example, injection molding in which a resin is injected into a mold. The processing accuracy of the insulator 16 is higher than that of the outer conductor 612 obtained by bending the metal plate. Therefore, the insulator 16 is easily brought into close contact with the outer peripheral surface of the outer conductor 12a. As a result, according to the male connector 110, the female connector 10, and the connector group 1, positioning of the male connector 110 and the female connector 10 in the front-back direction and the left-right direction can be performed with high accuracy. However, the outer peripheral surface of the outer conductor 112a and the outer peripheral surface of the outer conductor 12a may be in direct contact.

In addition, the male connector 110, the female connector 10, and the connector group 1 can suppress the intrusion or radiation of noise for the following reasons. More specifically, the lower ends of the center conductors 114 and 115 are surrounded by the outer conductor 112 a when viewed from the lower side, and do not exist outside the outer conductor 112 a. Thereby, in the male connector 110, the intrusion of noise into the center conductors 114, 115 and the noise from the center conductor 114, 115 to the outside of the outer conductor 112a are suppressed. For the same reason, in the female connector 10, noise is prevented from entering the center conductors 14, 15 and noise is radiated from the center conductors 14, 15 to the outside of the outer conductor 12a.
