[0003] [Patent Document 1] Japanese Patent Application Publication No. 2-273476 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the connector parts 6 and 7 of the relay connector device 5 are originally ready-made connectors that can be mated with the connectors 1 and 2. Therefore, using ready-made connectors as parts of the relay connector device 5 leads to high costs. Furthermore, ready-made connectors may cause impedance mismatching inside the connector parts 6 and 7. Therefore, the relay connector device 5 shown in FIG. 14 has a problem of degrading transmission characteristics in high-speed signal transmission.
[0006] The object of the present disclosure is to solve such problems and to provide a relay connector device that can suppress the high costs and deterioration of transmission characteristics caused by the connector portion. [Means for solving the problem]

[0017] Hereinafter, a specific configuration of this embodiment will be described with reference to the drawings. The following description shows a preferred embodiment of the present disclosure, and the scope of the present disclosure is not limited to the following embodiment. In the following description, items with the same reference numerals indicate substantially the same contents. Some reference numerals and hatching are omitted to avoid cluttering the drawings.
[0018] (Embodiment 1) A relay connector device according to a first embodiment will be described. FIG. 1 is a perspective view illustrating the relay connector device according to the first embodiment and connectors fitted to one side and the other side of the relay connector device. FIG. 2 is a perspective view illustrating the relay connector device according to the first embodiment. FIG. 3 is a cross-sectional view illustrating the relay connector device according to the first embodiment, taken along line III-III in FIG. 2. As shown in FIGS. 1 to 3, the relay connector device 100 relays a connector 200 and a connector 300.
[0019] The connector 200 includes a conductive shell 210, a plug 220, a harness 230, and a hood 240. The connector 200 may include a screw 250. The conductive shell 210 is, for example, a cylindrical shape with an elliptical cross section. Note that the conductive shell 210 is not limited to a cylindrical shape with an elliptical cross section, and may be a cylindrical shape with a rectangular cross section, etc., as long as it can be fitted into the relay connector device 100. The conductive shell 210 is, for example, made of metal. Note that the conductive shell 210 is not limited to being made of metal, as long as it is conductive. The conductive shell 210 is connected to, for example, a ground (GND) potential. The conductive shell 210 protrudes from an end face of the hood 240 to which the harness 230 is connected.
[0020] The harness 230 is a cord-like bundle of multiple wires. The hood 240 is a portion to which the conductive shell 210 and the plug 220 for fitting the connector 200 to the relay connector device 100 are attached. The plug 220 is disposed inside the cylindrical conductive shell 210 having an oval cross section. In this manner, the connector 200 has the cylindrical conductive shell 210 having an oval cross section protruding from the end face of the hood 240 to which the harness 230 is connected, and the plug 220 disposed inside the conductive shell 210. Note that the plug 220 is not limited to being disposed inside the cylindrical conductive shell 210 having an oval cross section, as long as the plug 220 is configured to receive the contact 128 of the printed circuit board 120 described later.
[0021] The connector 300 includes a conductive shell 310, a plug 320, a harness 330, a hood 340, and a screw 350. The conductive shell 310, the plug 320, the harness 330, the hood 340, and the screw 350 have the same functions as the conductive shell 210, the plug 220, the harness 230, the hood 240, and the screw 350.
[0022] The relay connector device 100 includes a housing 110, a printed board 120, and a shell connecting spring component 130. In Fig. 2, only the outline of the printed board 120 is shown in perspective to avoid complicating the drawing. The relay connector device 100 fits a connector 200 having a conductive shell 210 to one side of the housing 110. The relay connector device 100 also fits a connector 300 having a conductive shell 310 to the other side of the housing 110.
[0023] The housing 110 is cylindrical and has a through hole 113 that penetrates from an end face 111 on one side to an end face 112 on the other side. The housing 110 may be formed by molding. The housing 110 is, for example, a rectangular tube. In that case, the end faces 111 and 112 of the housing 110 are rectangular. The corners of the housing 110 may be slightly rounded, such as by adding a corner R, as appropriate. The housing 110 may further include a triangular prism-shaped portion having an end face provided with a screw hole 114. In that case, the end faces 111 and 112 have a shape obtained by adding a triangle to a rectangle.
[0024] Here, for convenience of explanation of the relay connector device 100, an XYZ orthogonal coordinate system is introduced. For example, the direction perpendicular to the end face 111 is the X-axis direction, the direction from the end face 111 toward the end face 112 is the +X-axis direction, and the opposite direction to the +X-axis direction is the -X-axis direction. For example, one side is the -X-axis side, and the other side is the +X-axis side. The two directions perpendicular to the X-axis direction are the Y-axis direction and the Z-axis direction. Also, the +Z-axis direction is called the upward direction, and the -Z-axis direction is called the downward direction. The length in the Z-axis direction is called the height or thickness.
[0025] The housing 110 has screw holes 114 on the +Z axis direction side of the through hole 113 in the end face 111 and on the +Z axis direction side of the through hole 113 in the end face 112. A screw 250 protruding from an end face on the +X axis direction side of the hood 240 in the connector 200 is fixed to the screw hole 114 in the end face 111, and a screw 350 protruding from an end face on the -X axis direction side of the hood 340 in the connector 300 is fixed to the screw hole 114 in the end face 112. This makes it possible to strengthen the connection between the relay connector device 100 and the connectors 200 and 300. The housing 110 has a printed circuit board 120 built in inside the through hole 113.
[0026] The printed board 120 is disposed inside the housing 110. Specifically, the printed board 120 is disposed inside the through hole 113. The printed board 120 is, for example, a rectangular plate. The printed board 120 may be a paddle card. The printed board 120 has an end face 121 on the -X axis direction side, an end face 122 on the +X axis direction side, a plate surface 123 on the +Z axis direction side, a plate surface 124 on the -Z axis direction side, a side surface 125 on the -Y axis direction side, and a side surface 126 on the +Y axis direction side. Components 127 such as ICs and chip resistors are disposed on the plate surface 123. The components 127 may include a repeater IC that amplifies a signal that has become smaller due to transmission loss. In this manner, the printed board 120 built into the housing 110 is equipped with the components 127.
[0027] Contacts 128 are provided at the end of the printed board 120 on the -X axis direction side and the end of the printed board 120 on the +X axis direction side. The contacts 128 may be edge connectors. The contacts 128 are provided at the end of the printed board 120 on the -X axis direction side and the end of the printed board 120 on the +X axis direction side. Note that the contacts 128 are not limited to being provided at the end of the board surface 123, as long as they are provided at the end of the printed board 120 on the -X axis direction side and the end of the printed board 120 on the +X axis direction side. They may also be provided at the end of the board surface 124 on the -X axis direction side and the +X axis direction side, or on the end surface 121 and the end surface 122.
[0028] The contacts 128 may be provided only at the end of the printed board 120 in the -X-axis direction or only at the end of the printed board 120 in the +X-axis direction. In this case, the other end may have the connector portion of Patent Document 1. At least one end of the printed board 120 has the contacts 128. The contacts 128 are members inserted into the connector 200. When the contacts 128 are provided at both ends of the printed board 120, the contacts 128 are inserted into the connectors 200 and 300. Specifically, the contacts 128 provided at the end of the printed board 120 in the -X-axis direction are inserted into the plug 220 of the connector 200. The contacts 128 provided at the end of the printed board 120 in the +X-axis direction are inserted into the plug 320 of the connector 300.
[0029] The shell connecting spring part 130 is disposed inside the housing 110. Fig. 4 is a perspective view illustrating the shell connecting spring part 130 in the relay connector device 100 according to the first embodiment. Fig. 5 is an enlarged view illustrating a portion of the shell connecting spring part 130 in the relay connector device 100 according to the first embodiment. As shown in Figs. 4 and 5, the shell connecting spring part 130 has a main body portion 140, a spring piece 150, and a spring piece 160.
[0030] The main body 140 includes a plate-shaped portion 141, a folded portion 142, and a folded portion 143. The plate-shaped portion 141 is a plate extending in the X-axis direction. The folded portion 142 is connected to an end portion of the plate-shaped portion 141 on the -X-axis direction side. The folded portion 143 is connected to an end portion of the plate-shaped portion 141 on the +X-axis direction side. The folded portion 142 includes a portion 144 extending in the -Z-axis direction from an end portion of the plate-shaped portion 141 on the -X-axis direction side, and a portion 145 extending in the +X-axis direction from an end portion of the portion 144 on the -Z-axis direction. The folded portion 143 includes a portion 146 extending in the -Z-axis direction from an end portion of the plate-shaped portion 141 on the +X-axis direction side, and a portion 147 extending in the -X-axis direction from an end portion of the portion 146 on the -Z-axis direction side. The corners of the folded portion 142 and the folded portion 143 may be slightly rounded, such as rounded corners.
[0031] An elongated hole 148 extending in the X-axis direction is formed at the end of the plate-shaped portion 141 on the -X-axis direction side. An elongated hole 149 extending in the X-axis direction is formed at the end of the plate-shaped portion 141 on the +X-axis direction side. A spring piece 150 is disposed inside the hole 148, and a spring piece 160 is disposed inside the hole 149.
[0032] The spring piece 150 has a seesaw shape including a portion extending in a direction that diagonally intersects with the plate surface 123 of the printed circuit board 120. The spring piece 150 has a spring portion 151 and a U-shaped portion 152. The spring portion 151 includes a portion extending in a direction that diagonally intersects with the plate surface 123. In the spring piece 150, the end portion on the -X axis direction side of the spring portion 151 is located on the +Z axis direction side of the plate-shaped portion 141. The end portion on the +X axis direction side of the spring portion 151 may be located on the -Z axis direction side of the plate-shaped portion 141, or may be at the same height as the plate-shaped portion 141.
[0033] In the spring piece 150, the U-shaped portion 152 is connected to an end portion on the -X-axis direction side of the spring portion 151. The U-shaped portion 152 includes a portion 153 extending in the -Z-axis direction from the end portion on the -X-axis direction side of the spring portion 151, and a portion 154 extending in the +X-axis direction from the end portion on the -Z-axis direction of the portion 153.
[0034] One end of the spring piece 150, i.e., an end 155 on the +X-axis direction side of the spring portion 151, includes a spring contact point P1. The other end of the spring piece 150, i.e., a portion 153 which is an end on the -X-axis direction side of the U-shaped portion 152, includes a force point P2 which is pressed by the connector 200 in a mating direction (A in the figure) parallel to the plate surface 123 of the printed board 120. The mating direction in the connector 200 is the +X-axis direction. A portion between one end and the other end of the spring piece 150 includes a fulcrum P3 which is rotatably fixed to the plate-shaped portion 141 of the main body 140. Thus, as the connector 200 is mated, the connector 200 presses the portion 153 which is the force point P2 in the mating direction, and the end 155 which is the spring contact point P1 moves in a direction approaching the printed board 120 (B in the figure).
[0035] Specifically, before the connector 200 is mated, the U-shaped portion 152 protrudes from the end surface 111 of the housing 110. When the connector 200 is mated, the end surface of the hood 240 of the connector 200 on the +X-axis direction side presses the U-shaped portion 152 in the +X-axis direction. As a result, the spring portion 151 rotates around the fulcrum P3, and the end portion 155 of the spring portion 151 moves in the -Z-axis direction approaching the printed board 120. Therefore, the end portion 155, which is the spring contact point P1, contacts the conductive shell 210 of the connector 200. Here, the portion 153 including the force point P2 in the spring piece 150 is bent in the Z-axis direction perpendicular to the X-axis direction, which is the mating direction. Therefore, when the connector 200 presses the force point P2, it is possible to reduce friction with the force point P2, and thus it is possible to suppress the generation of wear powder.
[0036] The configuration of the spring piece 160 is the same as that of the spring piece 150, except that the orientation of each component of the spring piece 150 is opposite in the X-axis direction. Therefore, the shell-connecting spring part 130 has a spring contact P1 of the spring piece 150 that is pushed by the connector 200 and moves in a direction approaching the printed board 120 as the connector 200 is engaged. The shell-connecting spring part 130 also has a spring contact P1 of the spring piece 160 that is pushed by the connector 300 and moves in a direction approaching the printed board 120 as the connector 300 is engaged. When the connector 200 is engaged with the -X-axis direction side of the housing 110, the spring contact P1 of the spring piece 150 comes into contact with the conductive shell 210. When the connector 300 is engaged with the +X-axis direction side of the housing 110, the spring contact P1 of the spring piece 160 comes into contact with the conductive shell 310. This allows electrical continuity between the conductive shell 210 and the conductive shell 310.
[0037] The shell connecting spring component 130 may be formed as one component by punching a metal plate with a press and then bending the metal plate to form a single component. For example, a metal plate is punched with a press into a rectangular shape extending in the X-axis direction. Then, the spring pieces 150 and 160 are punched with a press near the end of the punched metal plate in the -X-axis direction and near the end of the punched metal plate in the +X-axis direction, respectively. This forms the main body 140, the spring pieces 150, and the spring pieces 160. Then, a rotatable fulcrum P3 is formed between the main body 140 and the spring pieces 150 and 160.
[0038] Also, the folded portion 142, the folded portion 143, the U-shaped portion 152, and the like are formed by bending. In this manner, the shell connecting spring part 130 can be integrally molded from a single part. This makes it possible to facilitate processing since there is no need to join multiple members. Note that the shell connecting spring part 130 may be formed by joining multiple members.
[0039] Next, the operation of the relay connector device 100 will be described. FIGS. 6 to 9 are schematic diagrams illustrating the operation of the relay connector device 100 according to the first embodiment. As shown in FIG. 6, first, the printed board 120 is built into the housing 110. Specifically, the printed board 120 on which the component 127 is mounted is inserted into the through hole 113 of the housing 110. At this time, the end 155 which is the spring contact P1 of the spring piece 150 and the end 165 which is the spring contact P1 of the spring piece 160 do not move in the -Z axis direction. Therefore, as shown in FIG. 7, the printed board 120 can be press-fitted into the housing 110 without the component 127 interfering with the spring contact P1 of the shell connection spring component 130, etc.
[0040] 8, the connector 200 is fitted into the relay connector device 100. Specifically, the conductive shell 210 of the connector 200 is fitted into the through hole 113 of the relay connector device 100, and the contact 128 is inserted into the plug 220. The end face on the +X-axis direction side of the hood 240 of the connector 200 presses the portion 153, which is the force point P2 of the spring piece 150, in the +X-axis direction, which is the fitting direction.
[0041] 9, the spring piece 150 rotates about the fulcrum P2. As a result, the end 155, which is the spring contact P1, moves in the -Z-axis direction toward the printed board 120. Therefore, the spring contact P1 comes into contact with the conductive shell 210. Also, the contact 128 of the printed board 120 comes into contact with the plug 220 arranged inside the conductive shell 210. In this manner, the connector 200 can be fitted into the relay connector device 100. Fitting the connector 300 into the relay connector device 100 is similar to fitting the connector 200, except that the X-axis direction is reversed.
[0042] Next, the effects of this embodiment will be described. The relay connector device 100 of this embodiment has contacts 128 that are directly inserted into the connector 200 at least on one end of the printed circuit board 120. Therefore, at least one connector unit as in Patent Document 1 can be eliminated as a component of the relay connector device 100. This makes it possible to suppress the increase in cost and the deterioration of transmission characteristics caused by the connector unit.
[0043] Also, contacts 128 that are directly inserted into connectors 200 and 300 may be provided at both ends of printed circuit board 120. Furthermore, spring contacts P1 that move in a direction approaching printed circuit board 120 may also be provided on both sides of shell connection spring component 130. In this way, if both sides of printed circuit board 120 are provided with contacts 128 such as edge connectors, it is possible to further suppress high costs and deterioration of transmission characteristics.
[0044] As the connector 200 is mated, the part 153 that becomes the force point P2 that comes into contact with the connector 200 is bent in a direction that is approximately perpendicular to the mating direction. Therefore, by pressing the part that becomes the force point P2 without rubbing it, the spring part 151 of the spring piece 150 can be rotated around the fulcrum P3. This makes it possible to suppress the generation of wear powder.
[0045] As the connector 200 is mated, the end 155 of the spring piece 150 is pushed by the connector 200 and moves in a direction approaching the printed board 120. Therefore, before the connector 200 is mated, the end 155 of the spring piece 150 has not moved in the -Z axis direction. Therefore, during manufacturing, when the printed board 120 is disposed in the housing 110, interference between the spring piece 150 and the component 127 mounted on the printed board 120 can be suppressed.
[0046] As in the connectors 1 and 2 in Patent Document 1, the connectors 1 and 2 having the convex mating parts 14 and 25 cannot be connected to each other. For this reason, for example, a relay connector device 5 having connector parts 6 and 7 with concave shapes at both ends is required. If the connector parts 6 and 7 are not used to reduce costs, it may be possible to obtain signal conduction between the connectors 1 and 2 by directly mating the connectors 1 and 2 with the printed board 8. However, it is necessary to connect the mating parts 14 and 25 of the connectors 1 and 2 to each other as GND, but as described above, if the connector parts 6 and 7 are not used to reduce costs, it is necessary to provide a separate GND connection structure. If ICs or chip parts are mounted on the printed board 8 as in the relay connector device 5 in Patent Document 1 described above, the thickness direction is thick. For this reason, if a separate GND connection structure is provided, the provided GND connection structure may come into contact with the ICs or chip parts mounted on the printed board 8 before coming into contact with the mating parts 14 and 25 of the connectors 1 and 2, and may be damaged.
[0047] In the relay connector device 100 of this embodiment, when the printed circuit board 120 is press-fitted, the end portion 155 serving as the spring contact P1 of the shell connection spring part 130 is kept away from the part 127 mounted on the printed circuit board 120. This makes it possible to suppress interference between the part 127 and the spring contact P1. Then, when the connector 200 is fitted, the spring contact P1 moves in a direction approaching the printed circuit board 120 and contacts the conductive shell 210. In this way, in the relay connector device 100 of this embodiment, the GND contact structure becomes effective only when the connector 200 is fitted. Therefore, it is possible to obtain a GND connection structure while preventing damage to the part 127 such as an IC or a chip part.
[0048] (Embodiment 2) Next, a relay connector device according to a second embodiment will be described. In the relay connector device of this embodiment, the spring piece has a cantilever structure. Figs. 10 to 13 are schematic diagrams illustrating the configuration and operation of a relay connector device 400 according to the second embodiment. As shown in Figs. 10 to 13, the relay connector device 400 of this embodiment includes a shell connecting spring part 430. The shell connecting spring part 430 includes a main body portion 440, a spring piece 450, and a spring piece 460.
[0049] 10, the spring piece 450 has a cantilever shape including a portion extending in a direction that diagonally intersects with the board surface 123 of the printed circuit board 120. One end of the spring piece 450, i.e., an end 455 on the -X axis direction side of the spring piece 450, includes a spring contact point P1. The other end of the spring piece 450, i.e., an end 456 on the +X axis direction side of the spring piece 450, includes a fulcrum P3 fixed to the main body part 440. Thus, the end 456 is at the same height as the main body part 440.
[0050] An end 455 of the spring piece 450 is located on the -Z-axis direction side of the main body 440. By positioning the end 455 on the +Z-axis direction side of the component 127 mounted on the printed board 120, as shown in Fig. 11, it is possible to arrange the printed board 120 inside the housing 110 while suppressing interference between the shell connecting spring component 430 such as the end 455 and the component 127.
[0051] As shown in FIG. 12, a portion between an end 455, which is one end of the spring piece 450, and an end 456, which is the other end, includes a force point P2 that is pressed by the connector 200 in a mating direction parallel to the board surface 123 of the printed board 120. The connector 200 includes an insertion portion 260 that protrudes from an end face on the +X axis direction side of the hood 240. The insertion portion 260 is a portion that is inserted into the housing 110. The force point P2 is pressed by the insertion portion 260 of the connector 200. Therefore, as shown in FIG. 13, when the connector 200 is mated, the connector 200 presses the force point P2 in the mating direction, so that the end 455, which is the spring contact P1, moves in a direction approaching the printed board 120. This allows the end 455, which is the spring contact P1, to come into contact with the conductive shell 210.
[0052] The structure and operation of the spring piece 460 is similar to that of the spring piece 450, except that the orientation of each component of the spring piece 450 is in the opposite direction in the X-axis direction.
[0053] According to this embodiment, the relay connector device 400 has spring pieces 450 and 460 with a cantilever structure. When the connector 200 is mated, the insertion part 260 inserted into the housing 110 presses the force point P2 between the end 455 and the end 456, so that the end 455, which is the spring contact P1, moves in a direction approaching the printed board 120. As a result, the spring contact P1 comes into contact with the conductive shell 210. Note that since the insertion part 260 of the connector 200 presses the force point P2 obliquely, there is a concern that wear powder may be generated, but the connector part can be made unnecessary. Therefore, it is possible to suppress the high cost and the deterioration of the transmission characteristics caused by the connector part.
[0054] Although the embodiments of the present invention have been described above, the present disclosure includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited to the above-mentioned embodiments. In addition, the configurations in the first and second embodiments may be appropriately combined. [Explanation of symbols]
