[0004] However, the connector part 6 and the connector part 7 of the relay connector device 5 are originally commercially available connectors that can be respectively assembled to the connector 1 and the connector 2. Therefore, using commercially available connectors as components of the relay connector device 5 results in high costs. In addition, commercially available connectors may cause impedance mismatching inside the connector part 6 and the connector part 7. Therefore, Fig.14 The relay connector device 5 shown has a problem in that the transmission characteristics deteriorate during high-speed signal transmission.

[0030] Hereinafter, the specific structure of the present embodiment will be described with reference to the accompanying drawings. The following description shows a preferred embodiment of the present case, and the scope of the present case is not limited to the following embodiment. In the following description, the same reference numerals are given to substantially the same contents. In order to avoid confusion in the drawings, some reference numerals and hatching are omitted.

[0031] (First embodiment)

[0032] A relay connector device according to a first embodiment will be described below. Figure 1 : is a perspective view showing an example of the relaying connector device according to the first embodiment and connectors respectively fitted to one side and the other side of the relaying connector device. Figure 2 is a perspective view showing an example of the relay connector device according to the first embodiment. Figure 3 is a cross-sectional view showing an example of a relay connector device according to the first embodiment, and shows a cross-sectional view along Figure 2 The cross section is taken along line III-III. Figures 1 to 3 As shown, the relay connector device 100 relays the connector 200 and the connector 300 .

[0033] The connector 200 has a conductive shell 210, a plug 220, a wiring harness 230 and a shield 240. The connector 200 may have a screw 250. The conductive shell 210 is, for example, a cylindrical shape with an oblong cross section. The conductive shell 210 is not limited to a cylindrical shape with an oblong cross section, but may be a cylindrical shape with a square cross section, etc., as long as it can be assembled to the relay connector device 100. The conductive shell 210 is, for example, made of metal. The conductive shell 210 is not limited to being made of metal, as long as it has conductivity. The conductive shell 210 is connected to, for example, a ground (GND) potential. The conductive shell 210 protrudes from the end face of the shield 240 connected to the wiring harness 230.

[0034] The wiring harness 230 is in the shape of a rope in which a plurality of electric wires are bundled together. The shield 240 is a portion to which the conductive shell 210 and the plug 220 for assembling the connector 200 to the relay connector device 100 are attached. The plug 220 is disposed inside the cylindrical conductive shell 210 having an oblong cross section. As described above, the connector 200 has a cylindrical conductive shell 210 and the plug 220 disposed inside the conductive shell 210, and the cylindrical conductive shell 210 has an oblong cross section protruding from the end face of the shield 240 connected to the wiring harness 230. It should be noted that the plug 220 is not limited to being disposed inside the cylindrical conductive shell 210 having an oblong cross section, as long as it can be inserted by the contact point 128 of the printed board 120 described later.

[0035] The connector 300 includes a conductive shell 310, a plug 320, a wire harness 330, a shield 340, and a screw 350. The conductive shell 310, the plug 320, the wire harness 330, the shield 340, and the screw 350 have the same functions as the conductive shell 210, the plug 220, the wire harness 230, the shield 240, and the screw 250, respectively.

[0036] The relay connector device 100 includes a housing 110, a printed circuit board 120, and a spring assembly 130 for housing connection. Figure 2 In the figure, only the outline of the printed circuit board 120 is shown to avoid confusion in the drawing. In the relay connector device 100, the connector 200 having the conductive shell 210 is assembled to one side of the housing 110. In addition, in the relay connector device 100, the connector 300 having the conductive shell 310 is assembled to the other side of the housing 110.

[0037] The shell 110 is cylindrical and has a through hole 113 extending from one end face 111 to the other end face 112. The shell 110 may be molded. The shell 110 is, for example, a square cylinder. In this case, the end face 111 and the end face 112 of the shell 110 are square. The corners of the shell 110 may appropriately have slight rounded corners, such as chamfered corners. The shell 110 may also include a triangular prism portion, the end face of which is provided with a screw hole 114. In this case, the end face 111 and the end face 112 have a combination of a rectangular shape and a triangular shape.

[0038] Here, in order to facilitate the explanation of the relay connector device 100, an XYZ orthogonal coordinate axis system is introduced. For example, the direction orthogonal to the end face 111 is defined as the X-axis direction, the direction from the end face 111 to the end face 112 is defined as the positive direction of the X-axis, and the direction opposite to the positive direction of the X-axis is defined as the negative direction of the X-axis. For example, one side is defined as the negative direction side of the X-axis, and the other side is defined as the positive direction side of the X-axis. The two directions perpendicular to the X-axis direction are defined as the Y-axis direction and the Z-axis direction. The positive direction of the Z-axis is called upward, and the negative direction of the Z-axis is called downward. The length in the Z-axis direction is called height or thickness.

[0039] The housing 110 has threaded holes 114 located on the positive Z-axis side of the through hole 113 of the end face 111 and on the positive Z-axis side of the through hole 113 of the end face 112. The screw 250 protruding from the end face on the positive X-axis side of the shield 240 in the connector 200 is fixed to the screw hole 114 in the end face 111, and the screw 350 protruding from the end face on the negative X-axis side of the shield 340 in the connector 300 is fixed to the screw hole 114 in the end face 112. Therefore, the connection between the relay connector device 100, the connector 200, and the connector 300 can be strengthened. The housing 110 includes the printed circuit board 120 located inside the through hole 113.

[0040] The printed circuit board 120 is arranged inside the housing 110. Specifically, the printed circuit board 120 is arranged in the through hole 113. The printed circuit board 120 is, for example, a rectangular plate. The printed circuit board 120 may be a paddle card. The printed circuit board 120 has an end face 121 on the negative direction side of the X-axis, an end face 122 on the positive direction side of the X-axis, a board surface 123 on the positive direction side of the Z-axis, a board surface 124 on the negative direction side of the Z-axis, a side surface 125 on the negative direction side of the Y-axis, and a side surface 126 on the positive direction side of the Y-axis. Components 127 such as ICs and chip resistors are arranged on the board surface 123. The component 127 may include a repeater IC that amplifies a signal reduced due to transmission loss. Therefore, the printed circuit board 120 included in the housing 110 is equipped with the component 127.

[0041] The contact point 128 is arranged at the end of the negative X-axis side and the positive X-axis side of the printed circuit board 120. The contact point 128 may be an edge connector. The contact point 128 is arranged at the end of the negative X-axis side and the positive X-axis side of the board surface 123 of the printed circuit board 120. The contact point 128 may be arranged not only at the end of the board surface 123, but also at the end of the negative X-axis side and the positive X-axis side of the board surface 124, or may be arranged on the end surface 121 and the end surface 122, as long as it is arranged at the end of the negative X-axis side and the positive X-axis side of the printed circuit board 120.

[0042] The contact point 128 may be provided only at the end of the printed circuit board 120 on the negative direction side of the X axis, or only at the end on the positive direction side of the X axis. In this case, the other end may have a connector component of Japanese Unexamined Patent Application Publication No. H02-273476. At least one end of the printed circuit board 120 has the contact point 128. The contact point 128 is a member inserted into the connector 200. When the contact point 128 is provided at both ends of the printed circuit board 120, each contact point 128 is inserted into the connector 200 and the connector 300. Specifically, the contact point 128 provided at the end of the printed circuit board 120 on the negative direction side of the X axis is inserted into the plug 220 of the connector 200. The contact point 128 provided at the end of the printed circuit board 120 on the positive direction side of the X axis is inserted into the plug 320 of the connector 300.

[0043] A spring assembly 130 for shell connection is disposed within the housing 110 . Figure 41 is a perspective view showing an example of the spring assembly 130 for case connection in the relay connector device 100 according to the first embodiment. Figure 5 FIG. 2 is an enlarged view showing an example of a portion of the spring assembly 130 for shell connection in the relay connector device 100 according to the first embodiment. Figure 4 and Figure 5 As shown, the spring assembly 130 for shell connection has a body portion 140 , a spring leaf 150 and a spring leaf 160 .

[0044] The main body 140 includes a plate-like portion 141, a folding portion 142, and a folding portion 143. The plate-like portion 141 is in a plate shape extending in the X-axis direction. The folding portion 142 connects the end of the plate-like portion 141 on the negative X-axis side. The folding portion 143 connects the end of the plate-like portion 141 on the positive X-axis side. The folding portion 142 includes a portion 144 extending from the end of the plate-like portion 141 on the negative X-axis side to the negative Z-axis direction, and a portion 145 extending from the end of the portion 144 on the negative Z-axis side to the positive X-axis direction. The folding portion 143 includes a portion 146 extending from the end of the plate-like portion 141 on the positive X-axis side to the negative Z-axis direction, and a portion 147 extending from the end of the portion 146 on the negative Z-axis side to the negative X-axis direction. The corners of the folding portion 142 and the folding portion 143 may be appropriately slightly rounded, such as chamfered.

[0045] A long hole 148 extending in the X-axis direction is formed at the end of the plate-shaped portion 141 on the negative X-axis direction side. A long hole 149 extending in the X-axis direction is formed at the end of the plate-shaped portion 141 on the positive X-axis direction side. The spring piece 150 is disposed in the hole 148, and the spring piece 160 is disposed in the hole 149.

[0046] The spring piece 150 has a seesaw shape and includes a portion extending in a direction obliquely intersecting the board surface 123 of the printed circuit board 120. The spring piece 150 includes a spring portion 151 and a U-shaped portion 152. The spring portion 151 includes a portion extending in a direction obliquely intersecting the board surface 123. In the spring piece 150, the end of the spring portion 151 on the negative direction side of the X axis is located on the positive direction side of the Z axis relative to the plate-shaped portion 141. The end of the spring portion 151 on the positive direction side of the X axis may be located on the negative direction side of the Z axis relative to the plate-shaped portion 141, or may be located at the same height as the plate-shaped portion 141.

[0047] In the spring piece 150, the U-shaped portion 152 connects the end of the spring portion 151 on the negative direction side of the X axis. The U-shaped portion 152 includes a portion 153 extending from the end of the spring portion 151 on the negative direction side of the X axis to the negative direction of the Z axis, and a portion 154 extending from the negative direction side of the end 153 to the positive direction of the X axis.

[0048] One end of the spring piece 150, i.e., the end 155 of the spring portion 151 on the positive direction side of the X axis, includes a spring contact point P1. The other end of the spring piece 150, i.e., the portion 153 of the end of the U-shaped portion 152 on the negative direction side of the X axis, includes a force point P2 pushed by the connector 200 along the assembly direction (indicated as direction A in the figure) parallel to the board surface 123 of the printed circuit board 120. The assembly direction of the connector 200 is the positive direction of the X axis. The portion between the one end and the other end of the spring piece 150 includes a pivot point P3, which is rotatably fixed to the plate-shaped portion 141 of the body portion 140. Therefore, during the assembly operation of the connector 200, the connector 200 pushes the portion 153 as the force point P2 along the assembly direction, so that the end 155 as the spring contact point P1 moves in a direction (indicated as direction B in the figure) toward the printed circuit board 120.

[0049] Specifically, before the connector 200 is assembled, the U-shaped portion 152 protrudes from the end surface 111 of the housing 110. When the connector 200 is assembled, the end surface of the shield 240 of the connector 200 located on the positive direction side of the X-axis pushes the U-shaped portion 152 in the positive direction of the X-axis. As a result, the spring portion 151 rotates around the pivot point P3, so that the end 155 of the spring portion 151 moves toward the printed circuit board 120 in the negative direction of the Z-axis. Therefore, the end 155 as the spring contact point P1 contacts the conductive shell 210 of the connector 200. Here, the portion 153 of the spring sheet 150 including the force point P2 is bent in the Z-axis direction orthogonal to the X-axis direction as the assembly direction. Therefore, when the connector 200 presses the force point P2, the friction with the force point P2 can be reduced, thereby suppressing the generation of wear debris.

[0050] The structure of the spring piece 160 is similar to that of the spring piece 150, except that each portion of the spring piece 150 is oppositely oriented in the X-axis direction. Therefore, the spring assembly 130 for shell connection has the spring contact point P1 of the spring piece 150, and during the assembly operation of the connector 200, the spring piece 150 is pushed by the connector 200 and moves in the direction toward the printed circuit board 120. The spring assembly 130 for shell connection has the spring contact point P1 of the spring piece 160, and during the assembly operation of the connector 300, the spring piece 160 is pushed by the connector 300 and moves in the direction toward the printed circuit board 120. When the connector 200 is assembled to the negative side of the X-axis direction of the housing 110, the spring contact point P1 of the spring piece 150 contacts the conductive housing 210. When the connector 300 is assembled to the positive side of the X-axis direction of the housing 110, the spring contact point P1 of the spring piece 160 contacts the conductive housing 310. As a result, the conductive shell 210 and the conductive shell 310 become conductive.

[0051] The spring assembly 130 for shell connection can be composed of a single component, which is punched out from a metal plate using a punching machine and then integrally formed by bending. For example, a metal plate is punched into a rectangular shape extending along the X-axis direction using a punching machine. Then, the spring piece 150 and the spring piece 160 are punched out by a punching machine near the ends of the negative direction side of the X-axis and the positive direction side of the X-axis of the punched metal plate. In this way, the body portion 140, the spring piece 150 and the spring piece 160 are formed. A rotatable pivot point P3 is formed between the body portion 140 and the spring piece 150 and the spring piece 160.

[0052] The folded portion 142, the folded portion 143 and the U-shaped portion 152 are formed by bending. In this way, the spring assembly 130 for shell connection can be integrally formed by a single component. As a result, there is no need to join a plurality of components, so that machining can be easily performed. The spring assembly 130 for shell connection can be formed by connecting a plurality of components.

[0053] Next, the operation of the relay connector device 100 will be described. Figures 6 to 9 1 is a schematic diagram showing an operation example of the relay connector device 100 according to the first embodiment. Figure 6As shown, the printed circuit board 120 is first contained in the housing 110. Specifically, the printed circuit board 120 with the component 127 installed is inserted into the through hole 113 of the housing 110. At this time, the end 155 of the spring contact point P1 of the spring sheet 150 and the end 165 of the spring contact point P1 of the spring sheet 160 do not move in the negative direction of the Z axis. Therefore, as Figure 7 As shown, the printed circuit board 120 may be press-fitted into the housing 110 without causing the spring contact point P1 and the like of the spring assembly 130 for shell connection to interfere with the assembly 127 .

[0054] Next, if Figure 8 As shown, the connector 200 is assembled to the relay connector device 100. Specifically, the conductive shell 210 of the connector 200 is assembled to the through hole 113 of the relay connector device 100, and the contact point 128 is inserted into the plug 220. The end surface of the shield 240 of the connector 200 along the positive direction of the X-axis pushes the portion 153, which is the force point P2 of the spring piece 150, along the positive direction of the X-axis (i.e., the assembly direction).

[0055] Then, if Fig. 9 As shown, the spring sheet 150 rotates around the pivot point P3. Therefore, the end 155 as the spring contact point P1 moves in the negative direction of the Z axis (i.e., in the direction toward the printed circuit board 120). Therefore, the spring contact point P1 contacts the conductive shell 210. The contact point 128 of the printed circuit board 120 contacts the plug 220 disposed in the conductive shell 210. In this way, the connector 200 can be assembled to the relay connector device 100. The process of assembling the connector 300 to the relay connector device 100 is the same as the process of assembling the connector 200 to the relay connector device 100, except that the connector 300 is opposite in the X-axis direction.

[0056] Next, the effect of this embodiment is described. The relay connector device 100 according to this embodiment includes a contact point 128 at least at one end of the printed circuit board 120, which is directly inserted into the connector 200. Therefore, at least one connector component described in Japanese Unexamined Patent Application Publication No. H02-273476 as a component of the relay connector device 100 can be eliminated. This suppresses the cost increase and transmission characteristic degradation caused by the connector component.

[0057] Furthermore, the contact points 128 directly inserted into the connector 200 and the connector 300 may be provided at both ends of the printed circuit board 120. Furthermore, the spring contact points P1 moving toward the printed circuit board 120 may be provided on both sides of the spring assembly 130 for case connection. As described above, if both sides of the printed circuit board 120 have the contact points 128 such as edge connectors, it becomes possible to further suppress cost increase and deterioration of transmission characteristics.

[0058] During the assembly operation of the connector 200, the portion 153 serving as the force point P2 in contact with the connector 200 is bent in a direction substantially orthogonal to the assembly direction. Therefore, by frictionlessly pressing the portion serving as the force point P2, the spring portion 151 of the spring sheet 150 can rotate about the pivot point P3. This helps suppress the generation of wear debris.

[0059] During the assembly operation of the connector 200, the end 155 of the spring piece 150 is pushed by the connector 200 and moves in the direction toward the printed circuit board 120. Therefore, before the assembly operation of the connector 200, the end 155 of the spring piece 150 does not move in the negative direction of the Z axis. Therefore, during the manufacturing process of placing the printed circuit board 120 in the housing 110, interference between the component 127 mounted on the printed circuit board 120 and the spring piece 150 can be suppressed.

[0060] Similar to the connector 1 and the connector 2 in Japanese Unexamined Patent Application Publication No. H02-273476, the connector 1 and the connector 2 having the protruding fitting portion 14 and the fitting portion 25 cannot be connected to each other. Therefore, for example, a relay connector device 5 having the recessed connector part 6 and the connector part 7 at both ends is required. When the connector part 6 and the connector part 7 are not used in order to reduce costs, the conduction between the signals of the connector 1 and the connector 2 can be achieved by directly fitting the connector 1 and the connector 2 to the printed circuit board 8. However, it is necessary to ground the fitting portion 14 and the fitting portion 25 of the connector 1 and the connector 2, but as described above, when the connector part 6 and the connector part 7 are not used in order to reduce costs, it is necessary to provide a separate GND connection structure. When an IC or chip component is mounted on the printed circuit board 8, as in the case of the relay connector device 5 described in Japanese Unexamined Patent Application Publication No. H02-273476, the length of the relay connector device 5 in the thickness direction is increased. Therefore, when the GND connection structure is set separately, the set GND connection structure contacts the IC and chip components mounted on the printed circuit board 8 before contacting the assembly parts 14 and the assembly parts 25 of the connector 1 and the connector 2, so there is a risk of damage.

[0061] In the relay connector device 100 according to the present embodiment, when the printed circuit board 120 is pressed, the end 155 of the spring contact point P1 of the spring component 130 used for shell connection is kept away from the component 127 mounted on the printed circuit board 120. Therefore, it is possible to suppress interference between the component 127 and the spring contact point P1. When the connector 200 is assembled, the spring contact point P1 moves in the direction toward the printed circuit board 120 and contacts the conductive shell 210. As described above, in the relay connector device 100 according to the present embodiment, when the connector 200 is assembled, the contact structure of GND is first effective. Therefore, the connection structure of GND can be obtained while preventing the breakage of the component 127 such as IC and chip components.

[0062] (Second embodiment)

[0063] Next, a relay connector device according to a second embodiment will be described. In the relay connector device according to the present embodiment, the spring piece has a cantilever beam structure. Figures 10 to 13 1 is a schematic diagram showing an example of the configuration and operation of the relay connector device 400 according to the second embodiment. Figures 10 to 13As shown, the relay connector device 400 according to this embodiment includes a spring assembly 430 for shell connection. The spring assembly 430 for shell connection includes a body portion 440, a spring piece 450 and a spring piece 460.

[0064] like Fig.10 As shown, the spring piece 450 has a cantilever beam shape, including a portion extending in a direction obliquely intersecting the board surface 123 of the printed circuit board 120. One end of the spring piece 450 (i.e., the end 455 of the spring piece 450 on the negative side of the X-axis) includes a spring contact point P1. The other end of the spring piece 450 (i.e., the end 456 of the spring piece 450 on the positive side of the X-axis) includes a pivot point P3 fixed to the body part 440. Therefore, the end 456 has the same height as the body part 440.

[0065] The end 455 of the spring sheet 450 is located in the negative direction of the Z axis relative to the main body 440. By positioning the end 455 in the positive direction of the Z axis relative to the component 127 mounted on the printed circuit board 120 (eg Fig.11 As shown), the printed circuit board 120 can be disposed inside the housing 110 while suppressing interference between the spring assembly 430 (eg, the end 455 ) for shell connection and the assembly 127 .

[0066] like Fig.12 As shown, a portion between the end 455 as one end of the spring sheet 450 and the end 456 as the other end of the spring sheet 450 includes a force point P2, and the force point P2 is pushed by the connector 200 along the assembly direction parallel to the board surface 123 of the printed circuit board 120. The connector 200 includes an insertion portion 260 protruding from the end surface of the shield 240 on the positive direction side of the X-axis. The insertion portion 260 is a portion inserted into the housing 110. The force point P2 is pushed by the insertion portion 260 of the connector 200. Therefore, as Fig.13 As shown, during the assembly operation of the connector 200, the connector 200 pushes the force point P2 in the assembly direction, so that the end 455 as the spring contact point P1 moves in the direction toward the printed circuit board 120. As a result, the end 455 as the spring contact point P1 can contact the conductive shell 210.

[0067] The structure and operation of the spring piece 460 are similar to those of the spring piece 450 , except that the orientation of each portion of the spring piece 450 is opposite in the X-axis direction.

[0068] According to the present embodiment, the relay connector device 400 has the spring piece 450 and the spring piece 460 of the cantilever beam structure. During the assembly operation of the connector 200, the insertion portion 260 inserted into the housing 110 pushes the force point P2 between the end portion 455 and the end portion 456, so that the end portion 455 as the spring contact point P1 moves in the direction toward the printed circuit board 120. As a result, the spring contact point P1 contacts the conductive shell 210. Since the insertion portion 260 of the connector 200 pushes the force point P2 obliquely, the connector component can be eliminated, although there is a problem that wear debris may be generated. This suppresses the cost increase and transmission characteristic degradation caused by the connector component.

[0069] Although the embodiments of the present invention have been described above, the present invention includes appropriate modifications without departing from the objects and advantages thereof, and the present invention is not limited to the above-described embodiments.

[0071] From the disclosure of this description, it is obvious that the embodiments of the present invention can be changed in many ways. Such changes should not be regarded as departing from the spirit and scope of the present invention, and all such modifications obvious to those skilled in the art are intended to be included in the scope of the appended claims.
