[0029] The specific structure of the present invention is described below with reference to the accompanying drawings. The following description only shows the preferred embodiments of the present invention, and the scope of the present invention is not limited to the embodiments described below. In the following description, the same reference numerals are given to substantially the same elements. For the clarity of the drawings, some reference numerals and hatching are omitted.

[0030] Before describing the coaxial connector device according to the first embodiment, a coaxial connector device of a comparative example will be described for comparison. This will clarify the features of the coaxial connector device according to the first embodiment.

[0031] <Comparative Example>

[0032] Figure 1 1 is a perspective view showing each component included in the coaxial connector device 101 according to the comparative example. Figure 1 As shown, the coaxial connector device 101 according to the comparative example includes an outer housing 110 , a die casting 120 , a shield shell 130 , a GND shell 140 , an inner housing 150 , and contacts 160 .

[0033] In order to facilitate the description of the coaxial connector device 101 and the coaxial connector device 1 described later, an xyz orthogonal coordinate axis system is adopted. For example, the axial direction of the coaxial connector device 101, etc. is called the x-axis direction, and the two directions orthogonal to the x-axis are called the y-axis direction and the z-axis direction. In some cases, the +z-axis direction is called upward, and the surface on the +z-axis direction side is called the upper surface. In addition, the -z-axis direction is called downward, and the surface on the -z-axis direction side is called the lower surface. In some cases, the +y-axis direction and the -y-axis direction are called lateral directions, and the surface on the +y-axis direction side and the surface on the -y-axis direction side are called side surfaces. It should be noted that upward, downward, upper surface, lower surface, lateral direction, and side surfaces are terms used for the convenience of describing the coaxial connector device 101, etc., and do not indicate the setting direction of the coaxial connector device 101, etc. The following describes each structure.

[0034] <Outer shell>

[0035] The outer shell 110 is tubular. For example, the outer shell 110 has a square tube shape. The outer shell 110 includes a main body 111 and an insertion portion 112. The main body 111 includes a portion on the -x-axis side of the outer shell 110. The insertion portion 112 includes a portion on the +x-axis side of the outer shell 110. The width of the main body 111 in the y-axis direction and the width of the z-axis direction are greater than the width of the insertion portion 112 in the y-axis direction and the width of the z-axis direction. The insertion portion 112 is configured to be engaged with a mating portion 122 provided on the -x-axis side of the die casting 120. Specifically, the insertion portion 112 is used to be assembled between a mating plate 122a and a mating plate 122b.

[0036] A protrusion 113 extending toward the +x-axis direction is formed on the end surface of the insertion portion 112 on the +x-axis direction side. A plurality of protrusions 113 may be formed. The protrusion 113 is configured to be inserted into the insertion hole 123 in the die casting 120 when the insertion portion 112 is engaged with the engagement portion 122 of the die casting 120.

[0037] The outer shell 110 has a through hole 114 extending from the end surface of the main body 111 on the -x-axis direction to the end surface of the insertion portion 112 on the +x-axis direction. The through hole 114 is arranged with its central axis along the x-axis direction. The GND shell 140, the inner shell 150, the contact 160 and other components are used to be inserted into the through hole 114.

[0038] The outer shell 110 includes an insulator as a material. For example, the outer shell 110 includes a resin as a material. It should be noted that the outer shell 110 may also include an insulator other than a resin, as long as it contains an insulator.

[0039] <Die castings>

[0040] The die casting 120 includes a main body 121 and a fitting portion 122. The fitting portion 122 is connected to the end face of the main body 121 on the -x-axis direction side. The fitting portion 122 has two plate-shaped fitting plates 122a and 122b facing each other in the y-axis direction. The fitting plate 122a is arranged on the -y-axis direction side of the end face on the -x-axis direction side of the main body 121, and the fitting plate 122b is arranged on the +y-axis direction side of the end face on the -x-axis direction side of the main body 121. The insertion portion 112 of the outer shell 110 is assembled between the fitting plate 122a and the fitting plate 122b. Specifically, the insertion portion 112 of the outer shell 110 is installed between the fitting plate 122a and the fitting plate 122b, and the shielding shell 130 is placed therebetween.

[0041] An insertion hole 123 is formed at the end surface of the main body 121 on the -x axis direction side. The same number of insertion holes 123 as the protrusions 113 may be formed. The insertion holes 123 are used to insert the protrusions 113 of the outer housing 110.

[0042] The die-cast part 120 has a through-hole 124 that penetrates from the end face on the -x-axis direction side of the main body part 121 to the end face on the +x-axis direction side of the main body part 121. The through-hole 124 is arranged with its central axis along the x-axis direction. The insertion hole 123 and the through-hole 124 are formed between the fitting plates 122a and 122b that are connected to each other on the end face on the -x-axis direction side of the main body part 121. Components such as the GND housing 140, the inner housing 150, and the contact part 160 are inserted into the through-hole.

[0043] The die-cast part 120 contains a conductor as the material. For example, the die-cast part 120 may include metals such as aluminum and zinc as the material. The die-cast part 120 can be manufactured by die-casting. The die-cast part 120 is electrically connected to the ground potential (GND) together with the shielding case 130. A connection structure for connecting to a specific substrate can be formed on the -z-axis direction side of the die-cast part 120.

[0044] <shielding case>

[0045] The shielding case 130 includes a plate-shaped part 131 and a spring-shaped spring part 132. The plate-shaped part 131 has a plate surface on the +x-axis direction side and a plate surface on the -x-axis direction side. The plate-shaped part 131 has a through-hole 134 that penetrates the plate surface. The through-hole 134 is arranged with its central axis along the x-axis direction. The spring part 132 is connected to the end on the +z-axis direction side of the plate-shaped part 131. The spring part 132 is plate-shaped, for example. The spring part 132 is arranged such that its plate surface is inclined with respect to the XY plane. The spring part 132 has spring elasticity. The spring part 132 can be bent along the z-axis direction.

[0046] The plate-shaped part 131 is arranged on the end face on the -x-axis direction side of the main body part 121 of the die-cast part 120. Therefore, the plate-shaped part 131 is arranged between the fitting plate 122a and the fitting plate 122b. The through-hole 134 of the plate-shaped part 131 is arranged to surround the through-hole 124. The insertion part 112 of the outer housing 110 is arranged on the -x-axis direction side of the plate-shaped part 131. The spring part 132 is arranged on the upper surface of the main body part 121 of the die-cast part 120.

[0047] The shielding case 130 contains a conductor as the material. For example, the shielding case 130 contains a metal as the material. The shielding case 130 is electrically connected to the ground potential (GND) together with the die-cast part 120.

[0048] <GND housing>

[0049] The GND shell 140 has, for example, a tubular shape and has a through hole 144 that penetrates along the x-axis direction. The through hole 144 is arranged in a manner such that its central axis is along the x-axis direction. The GND shell 140 has, for example, a cylindrical shape. The GND shell 140 is disposed in the through hole 114, the through hole 134, and the through hole 124 that are connected by the outer shell 110, the plate-like portion 131, and the die-casting 120 that are nested in the x-axis direction. The inner shell 150 that is press-fitted with the contact 160 is inserted into the GND shell 140.

[0050] The GND shell member 140 includes a conductor as a material. For example, the GND shell member 140 includes a metal as a material. The GND shell member 140 is electrically connected to the ground potential (GND) together with the die casting 120 and the shield shell 130 .

[0051] <Inner Shell>

[0052] The inner housing 150 includes a tubular portion 151 and a support portion 152. The tubular portion 151 has, for example, a cylindrical shape. It should be noted that the tubular portion 151 is not limited to a cylindrical shape, as long as it is tubular. The tubular portion 151 is arranged in a manner such that its central axis is along the x-axis direction. The tubular portion 151 has a through hole 154 that passes from the end portion on the +x-axis direction side to the end portion on the -x-axis direction side. Therefore, the through hole 154 is arranged in a manner such that its central axis is along the x-axis direction.

[0053] The support portion 152 is connected to the +x-axis side of the tubular portion 151. The support portion 152 is in the shape of a plate extending in the z-axis direction, and has a plate surface facing the +x-axis side and a plate surface facing the -x-axis side. The tubular portion 151 is connected to the end portion on the +z-axis side of the plate surface on the -x-axis side of the support portion 152. Therefore, when viewed from the y-axis direction, the inner housing 150 is L-shaped. The support portion 152 has a through hole 154 at the end portion on the +z-axis side, which passes from the plate surface on the +x-axis side to the plate surface on the -x-axis side. The through hole 154 of the support portion 152 is connected to the through hole 154 of the tubular portion 151. The contact 160 is press-fitted into the connected through hole 154. In addition, a groove for the contact 160 to fit can also be formed on the plate surface on the +x-axis side of the support portion 152. The groove extends from the through hole 154 to the −z axis direction side on the plate surface of the support portion 152 on the +x axis direction side.

[0054] The inner case 150 includes an insulator as a material. For example, the inner case 150 includes a resin as a material. In addition, the inner case 150 may also include an insulator other than a resin as long as it includes an insulator.

[0055] <Contact>

[0056] The contact member 160 is L-shaped, and has a portion extending in the x-axis direction and a portion extending in the z-axis direction. The portion extending in the x-axis direction is called the first rod-shaped portion 161, and the portion extending in the z-axis direction is called the second rod-shaped portion 162. The end of the first rod-shaped portion 161 on the +x-axis direction side is connected to the end of the second rod-shaped portion 162 on the +z-axis direction side.

[0057] The first rod-shaped portion 161 has, for example, a distal portion, a middle portion, and a root portion in order from the -x axis direction side. The distal portion is in the shape of a round rod. The distal end of the distal portion is in a hemispherical shape. The middle portion and the root portion are in the shape of a square rod. The width between the sides of the square rod-shaped middle portion and the root portion opposite to each other is greater than the outer diameter of the round rod-shaped distal portion. The sides of the middle portion and the root portion are both provided with protrusions.

[0058] The first rod-shaped portion 161 of the contact 160 is press-fitted into the through hole 154 of the inner housing 150. In such a press-fitting process of the contact, a protrusion for maintaining the press-fit is required.

[0059] The second rod-shaped portion 162, for example, has a distal portion, a middle portion, and a root portion in order from the -z axis direction side. The distal portion is in the shape of a round rod. The distal end of the distal portion is in a hemispherical shape. The distal portion is connected to a specific substrate disposed on the -z axis direction side. The middle portion and the root portion are in the shape of a square rod. The width between the sides of the square rod-shaped middle portion and the root portion opposite to each other is greater than the outer diameter of the round rod-shaped distal portion.

[0060] The contact member 160 includes a conductor as a material. For example, the contact member 160 includes a metal as a material. The contact member 160 is used as a transmission path of a high-frequency signal.

[0061] <Assembly Method>

[0062] Figure 2 1 is a cross-sectional view showing an assembled state of a coaxial connector device 101 according to a comparative example. It should be noted that Figure 2 The outer shell 110 is omitted. Figure 2 As shown, the first rod-shaped portion 161 of the contact 160 is press-fitted into the through hole 154 of the inner housing 150 along the -x axis direction. The inner housing 150 press-fitted with the contact 160 is referred to as a contact unit 170. Therefore, the contact unit 170 includes the contact 160 and the inner housing 150.

[0063] The contact unit 170 is press-fitted into the through hole 144 of the GND case 140. The GND case 140 is inserted into the through hole 124 of the die casting 120 and the through hole 134 of the shield case 130 along the -x axis direction.

[0064] Figures 3 to 5 1 is a side view showing the connection operation of the outer housing 110 and the die casting 120 in the coaxial connector device 101 according to the comparative example. Figure 3 and Figure 4 As shown, the inserting portion 112 of the outer shell 110 is assembled between the inserting plate 122a and the inserting plate 122b of the die casting 120, and the shielding shell 130 is placed therebetween. Figure 5 As shown, the protrusion 113 of the outer housing 110 is press-fitted into the insertion hole 123 of the die casting 120. The GND housing 140 including the inner housing 150 and the contact 160 is inserted into the through hole 114 of the outer housing 110.

[0065] <Problems in Comparative Example>

[0066] In the coaxial connector device 101 according to the comparative example, the outer shell 110 is connected to the die-casting 120 by press-fitting the protrusion 113 of the outer shell 110 into the insertion hole 123 of the die-casting 120. In such a retaining structure formed by press-fitting of the outer shell 110, it is difficult to improve the retention in the x-axis direction. For example, when a cable is connected to the -x-axis direction side of the outer shell 110, the direction in which the cable extends and the press-fit direction are opposite directions. Therefore, when the cable is pulled, the outer shell 110 can be disassembled. Therefore, it is difficult to improve the connection reliability according to the coaxial connector device 101 of the comparative example, and a connection structure capable of improving the retention force between the outer shell 110 and the die-casting 120 is desired.

[0067] <First Embodiment>

[0068] A coaxial connector device according to a first embodiment will be described below. Figure 6 1 is a perspective view showing each component included in the coaxial connector device 1 according to the first embodiment. Figure 6 As shown, the coaxial connector device 1 according to the present embodiment includes an outer housing 10 , a die casting 20 , a shield shell 30 , and a contact unit 70 .

[0069] <Outer shell>

[0070] The outer shell 10 is tubular. For example, the outer shell 10 has a square tube shape. The outer shell 10 includes a main body 11, an L-shaped portion 12, and an L-shaped portion 13. The L-shaped portion 12 and the L-shaped portion 13 connect the end surface of the main body 11 on the +x-axis direction side. The L-shaped portion 12 and the L-shaped portion 13 are used as an interlocking part that is interlocked with the die casting 20.

[0071] The main body 11 has a through hole 14 extending from the end face on the -x-axis side to the end face on the +x-axis side. Therefore, the outer shell 10 has a through hole 14 extending along the x-axis direction. The cylindrical portion 25 of the die casting 20 and the contact unit 70 and other components are used to be inserted into the through hole 14. The L-shaped portion 12 and the L-shaped portion 13 are arranged parallel to the y-axis direction on the end face on the +x-axis side of the main body 11. The L-shaped portion 12 and the L-shaped portion 13 are arranged at both ends of the through hole 14 on the end face on the +x-axis side of the main body 11 in the y-axis direction.

[0072] The L-shaped portion 12 includes a first extension portion 12a and a second extension portion 12b. The first extension portion 12a extends from the end surface of the main body portion 11 on the +x-axis direction in the +x-axis direction. The second extension portion 12b extends from the end of the first extension portion 12a on the +x-axis direction in the +z-axis direction. A recess 12c is formed at the end of the first extension portion 12a on the -z-axis direction in the L-shaped portion 12.

[0073] The L-shaped portion 13 includes a first extension portion 13a and a second extension portion 13b. The first extension portion 13a extends from the end surface of the main body portion 11 on the +x-axis direction to the +x-axis direction. The second extension portion 13b extends from the end of the first extension portion 13a on the +x-axis direction to the +z-axis direction. A recess 13c is formed at the end of the first extension portion 13a on the -z-axis direction in the L-shaped portion 13. The L-shaped portion 12 and the L-shaped portion 13 are L-shaped when viewed from the y-axis direction.

[0074] The L-shaped portion 12 is inserted into an L-shaped groove 22 formed on the side surface of the die casting 20 on the -y-axis direction side. The recessed portion 12c is used to be assembled with the fitting portion 32a of the shielding shell 30. The L-shaped portion 13 is inserted into an L-shaped groove 23 formed on the side surface of the die casting 20 on the +y-axis direction side. The recessed portion 13c is used to be assembled with the fitting portion 33a of the shielding shell 30.

[0075] It should be noted that the "L" shape of the L-shaped portion 12 and the L-shaped portion 13 can also be reversed in the z-axis direction. Specifically, the second extension portion 12b can extend from the end of the first extension portion 12a on the +x-axis direction side to the -z-axis direction. In addition, the second extension portion 13b can also extend from the end of the first extension portion 13a on the +x-axis direction side to the -z-axis direction. At this time, the structure of the L-shaped groove 22 and the L-shaped groove 23 of the die casting 20 can also be reversed in the z-axis direction according to the "L" shape of the L-shaped portion 12 and the L-shaped portion 13. However, when the above-mentioned specific substrate is connected to the -z-axis direction side, the second extension portion 12b and the second extension portion 13b preferably extend to the +z-axis direction side opposite to the direction of connection to the specific substrate. Since the second extension portion 12b and the second extension portion 13b extend to the +z-axis direction side, they can cope with the force in the -z-axis direction of the specific substrate.

[0076] In addition, the L-shaped portion 12 and the L-shaped portion 13 do not need to be formed at the same time, and only one of them may be formed. Specifically, the L-shaped portion 12 and the like may be provided on at least one of the -y-axis side and the +y-axis side of the end surface on the +x-axis side of the main body portion 11 of the outer shell 10. In addition, according to the orientation of the L-shaped groove 22 and the L-shaped groove 23 of the die casting 20, the direction in which the second extension portion 12b and the second extension portion 13b extend is not limited to the z-axis direction, and they may extend along the y-axis direction, or extend in a direction inclined in the y-axis direction and the z-axis direction.

[0077] The outer shell 10 includes an insulator as a material. For example, the outer shell 10 includes a resin as a material. In addition, the outer shell 10 may include an insulator other than a resin as long as it includes an insulator.

[0078] <Die castings>

[0079] The die casting 20 includes a main body 21 and a cylindrical part 25. The cylindrical part 25 is connected to the end face of the main body 21 on the -x-axis direction side. The cylindrical part 25 has a cylindrical shape. The main body 21 has a through hole 24 that penetrates from the end face on the +x-axis direction side to the end face on the -x-axis direction side. The through hole 24 is connected to the cylindrical part 25. Therefore, the die casting 20 has a through hole 24 that penetrates from the end face on the +x-axis direction side of the main body 21 to the end face on the -x-axis direction side of the cylindrical part 25. The through hole 24 is arranged in a manner such that its central axis is along the x-axis direction. The through hole 24 can be connected to the through hole 14 of the outer shell 10. A component such as a contact unit 70 can be inserted into the through hole 24.

[0080] The main body 21 is formed with an L-shaped groove 22 and an L-shaped groove 23. Therefore, the die casting 20 includes the main body 21, the L-shaped groove 22 and the L-shaped groove 23. The L-shaped groove 22 and the L-shaped groove 23 are used as fitting parts to fit with the outer housing 10.

[0081] The L-shaped groove 22 is formed on the side of the main body 21 in the -y-axis direction. The L-shaped groove 22 includes a first groove portion 22a and a second groove portion 22b. The first groove portion 22a extends from the end surface of the main body 21 in the -x-axis direction to the +x-axis direction. The second groove portion 22b extends from the end of the first groove portion 22a in the +x-axis direction to the +z-axis direction. Therefore, the L-shaped groove 22 is L-shaped when viewed from the y-axis direction. A portion of the main body 21 remains on the -x-axis side of the second groove portion 22b.

[0082] The L-shaped groove 23 is formed on the side of the main body 21 on the +y-axis direction. The L-shaped groove 23 includes a first groove portion 23a and a second groove portion 23b. The first groove portion 23a extends from the end surface on the -x-axis direction side of the main body 21 to the +x-axis direction. The second groove portion 23b extends from the end of the first groove portion 23a on the +x-axis direction side to the +z-axis direction. Therefore, the L-shaped groove 23 is L-shaped when viewed from the y-axis direction. A portion of the main body 21 remains on the -x-axis direction side of the second groove portion 23b.

[0083] It should be noted that, as described above, when the "L" shapes of the L-shaped portions 12 and 13 are reversed in the z-axis direction, the structures of the L-shaped grooves 22 and 23 may be reversed in the z-axis direction according to the "L" shapes of the L-shaped portions 12 and 13. Specifically, the second groove portion 22b may extend from the end portion on the +x-axis side of the first groove portion 22a in the -z-axis direction. Furthermore, the second groove portion 23b may also extend from the end portion on the +x-axis side of the first groove portion 23a in the -z-axis direction.

[0084] In addition, the L-shaped groove 22 and the L-shaped groove 23 do not need to be formed at the same time, and only one of them may be formed. Specifically, the L-shaped groove 22 or the like may be formed on at least one of the -y-axis direction side and the +y-axis direction side of the main body 21 of the die casting 20. In addition, according to the orientation of the L-shaped portion 12 and the L-shaped portion 13 of the outer shell 10, the direction in which the second groove portion 22b and the second groove portion 23b extend is not limited to the z-axis direction, and they may extend along the y-axis direction, or extend in a direction inclined in the y-axis direction and the z-axis direction.

[0085] Figures 7 to 9 1 is a side view showing the connection operation of the outer housing 10 and the die casting 20 in the coaxial connector device 1 according to the first embodiment. Figures 7 to 9 In the embodiment, components other than the outer shell 10 and the die casting 20 are omitted. Figure 7 As shown, in the coaxial connector device 1, the outer shell 10 and the die casting 20 are in contact and connected in the x-axis direction parallel to the axial direction. First, the second extension portion 12b of the L-shaped portion 12 of the outer shell 10 is inserted into the first groove portion 22a of the L-shaped groove 22 along the +x-axis direction. And, the second extension portion 13b of the L-shaped portion 13 of the outer shell 10 is inserted into the first groove portion 23a of the L-shaped groove 23 along the +x-axis direction.

[0086] Then, if Figure 8 As shown, the second extension portion 12b is inserted into the first groove portion 22a along the +x-axis direction, and the second extension portion 12b is inserted into the second groove portion 22b of the L-shaped groove 22 along the +z-axis direction. Similarly, the second extension portion 13b of the L-shaped portion 13 of the outer shell 10 is inserted into the first groove portion 23a of the L-shaped groove 23 along the +x-axis direction, and then inserted into the second groove portion 23b of the L-shaped groove 23 along the +z-axis direction.

[0087] As such, the L-shaped portion 12 of the outer housing 10 is formed to be inserted into the L-shaped groove 22 of the die casting 20. In addition, the L-shaped portion 13 of the outer housing 10 is formed to be inserted into the L-shaped groove 23 of the die casting 20.

[0088] Fig.10 is a perspective view showing the outer housing 10 of the coaxial connector device 1 according to the first embodiment. Fig.11 2 is a perspective view showing the die casting 20 in the coaxial connector device 1 according to the first embodiment. Fig. 9 Region IX, Fig.10 , Fig.11 As shown, when the L-shaped portion 12 of the outer shell 10 is inserted into the L-shaped groove 22 of the die casting 20, the surface 19 of the second extension portion 12b of the L-shaped portion 12 on the -x-axis direction side contacts the surface 29 of the second groove portion 22b of the L-shaped groove 22 facing the +x-axis direction. When the L-shaped portion 13 of the outer shell 10 is inserted into the L-shaped groove 23 of the die casting 20, the surface 19 of the second extension portion 13b of the L-shaped portion 13 on the -x-axis direction side contacts the surface 29 of the second groove portion 23b of the L-shaped groove 23 facing the +x-axis direction. That is, the surface 29 on the +x-axis direction side of a portion of the main body 21 located on the -x-axis direction side of the second groove portion 22b and the second groove portion 23b contacts the surface 19 on the -x-axis direction side of the second extension portion 12b and the second extension portion 13b.

[0089] The die casting 20 includes a conductor as a material. For example, the die casting 20 may include a metal such as aluminum and zinc as a material. The die casting 20 may be manufactured by die casting. It should be noted that the die casting 20 is not limited to being manufactured by die casting, and may also be manufactured by other processes such as casting or a 3D printer. The die casting 20 is electrically connected to a ground potential (GND) together with the shielding shell 30.

[0090] <Shielding case>

[0091] Fig.12 is a side view showing the coaxial connector device 1 according to the first embodiment. Fig.13 is a cross-sectional view showing a coaxial connector device 1 according to a first embodiment, showing a Fig.12 Section along line XIII-XIII in FIG. Fig.14 is a cross-sectional view showing the fitting portion 33a in the coaxial connector device 1 according to the first embodiment, showing Fig.13 Magnified view of section XIV.

[0092] like Figure 6 and Figure 12 to Figure 14 As shown, the shielding shell 30 includes a main body 31, a covering part 32, a covering part 33, an assembly part 32a, an assembly part 33a and a spring member 35. The main body 31 has a plate surface on the +z-axis direction side and a plate surface on the -z-axis direction side. The main body 31 is arranged on the upper surface on the +z-axis direction side of the die casting 20. The spring member 35 is connected to the end of the main body 31 on the -x-axis direction side. The spring member 35 has, for example, a plate-like shape. The spring member 35 is arranged in a manner that its plate surface is inclined relative to the main body 31. The spring member 35 has spring elasticity. As a result, the spring member 35 can be bent along the z-axis direction.

[0093] The covering portion 32 and the covering portion 33 are respectively plate-shaped and have a plate surface on the +y-axis direction side and a plate surface on the -y-axis direction side. The ends of the covering portion 32 and the covering portion 33 on the +z-axis direction side are respectively connected to the two ends of the main body 31 in the y-axis direction. The covering portion 32 extends along the y-axis direction from the end of the main body 31 on the -y-axis direction side along the -z-axis direction. The covering portion 32 covers the L-shaped portion 12 in the y-axis direction. The assembly portion 32a is located at the end of the -z-axis direction side of the covering portion 32. The assembly portion 32a is embedded in the recess 12c of the L-shaped portion 12. For example, the assembly portion 32a is bent toward the +y-axis direction side to be embedded in the recess 12c. The assembly portion 32a thus fixes the L-shaped portion 12 of the outer shell 10.

[0094] The covering portion 33 extends from the end portion on the +y-axis side of the main body portion 31 along the y-axis direction along the -z-axis direction. The covering portion 33 covers the L-shaped portion 13 in the y-axis direction. The fitting portion 33a is located at the end portion on the -z-axis side of the covering portion 33. The fitting portion 33a is embedded in the recess 13c of the L-shaped portion 13. For example, the fitting portion 33a is bent toward the -y-axis direction side to be embedded in the recess 13c. The fitting portion 33a thus fixes the L-shaped portion 13 of the outer shell 10.

[0095] It should be noted that the covering portion 32 and the covering portion 33 do not need to be formed at the same time, and only one of them may be formed. Specifically, the covering portion 32 may extend from at least one of the ends on the -y axis side and the +y axis side of the main body 31 along the -z axis direction.

[0096] The shield shell 30 includes a conductor as a material. For example, the shield shell 30 includes a metal as a material. The shield shell 30 is electrically connected to a ground potential (GND) together with the die casting 20 .

[0097] <Contact element>

[0098] Fig.15 1 is a side view showing the contact unit 70 in the coaxial connector device 1 according to the first embodiment. Fig.15 As shown, the contact unit 70 includes a housing 50 and a contact member 60. The contact unit 70 is formed by insert molding. Specifically, the contact member 60 and the housing 50 are integrated with the contact unit 70 by insert molding. It should be noted that the contact unit 70 can also be formed by press-fitting the contact member 60 into the housing 50 along the -x axis direction.

[0099] The contact member 60 is L-shaped and has a portion extending in the x-axis direction and a portion extending in the z-axis direction. The portion extending in the x-axis direction is referred to as a first rod-shaped portion 61, and the portion extending in the z-axis direction is referred to as a second rod-shaped portion 62. The end of the first rod-shaped portion 61 on the +x-axis direction side is connected to the end of the second rod-shaped portion 62 on the +z-axis direction side.

[0100] The first rod-shaped portion 61, for example, has a distal portion 61a, a middle portion 61b, and a root portion 61c. The distal portion 61a has a round rod shape. The distal end of the distal portion 61a is hemispherical. The middle portion 61b and the root portion 61c are in the shape of a square rod. Therefore, the first rod-shaped portion 61 includes a square rod-shaped portion. In some cases, the middle portion 61b and the root portion 61c are also collectively referred to as a middle root component. The middle root component is connected to the distal portion 61a. The width between the opposite sides of the square rod-shaped middle portion 61b and the root portion 61c is greater than the outer diameter of the round rod-shaped distal portion 61a. Unlike the contact member 160 in the comparative example, no protrusions are formed on the sides of the middle portion 61b and the root portion 61c. In addition, the middle portion 61b and the root portion 61c may also be in the shape of a round rod. Specifically, the first rod-shaped portion 61 may include a round rod-shaped portion.

[0101] A portion of the first rod-shaped portion 61 of the contact 60 is assembled into the housing 50 by insert molding. Specifically, for example, a middle root portion of the first rod-shaped portion 61 is assembled into the housing 50. On the other hand, the distal end portion 61a of the first rod-shaped portion 61 protrudes from an end surface of the tubular portion 51 in the housing 50 on the -x-axis direction side.

[0102] The second rod-shaped portion 62 has, for example, a distal portion 62a, an intermediate portion 62b, and a root portion 62c. The distal portion 62a has a round rod shape. The distal end of the distal portion 62a is semi-spherical. The intermediate portion 62b and the root portion 62c are square rod-shaped. Therefore, the second rod-shaped portion 62 includes a square rod-shaped portion. In some cases, the intermediate portion 62b and the root portion 62c are also collectively referred to as a middle root component. The middle root component is connected to the distal portion 62a. The width between the opposite sides of the square rod-shaped intermediate portion 62b and the root portion 62c is greater than the outer diameter of the round rod-shaped distal portion 62a. A protrusion may be formed on the side of the intermediate portion 62b on the +x-axis direction side.

[0103] Thus, the contact member 60 includes a distal end portion 61a protruding from the housing 50 and a middle root member connected to the distal end portion 61a. In addition, the contact member 60 includes a distal end portion 62a protruding from the housing 50 and a middle root member connected to the distal end portion 62a. At least a portion of the middle root member is incorporated into the housing 50.

[0104] The contact member 60 includes a conductor as a material. For example, the contact member 60 includes a metal as a material. The contact member 60 is used as a transmission path of a high-frequency signal.

[0105] The housing 50 includes a tubular portion 51 and a supporting portion 52. The tubular portion 51 has, for example, a cylindrical shape. In addition, the tubular portion 51 is not limited to a cylindrical shape, as long as it is cylindrical. The tubular portion 51 is arranged in a manner such that its central axis is along the x-axis direction. The tubular portion 51 of the housing 50 encapsulates a portion of the contact 60. Thus, a portion of the contact 60 is provided in the housing 50. Specifically, the middle portion 61b and the root portion 61c of the first rod-shaped portion 61 of the contact 60 are provided in the tubular portion 51.

[0106] The tubular portion 51 has a hole 53 on its side. In addition, the support portion 52 may also have a hole 53. A portion of the contact member 60 is exposed through the hole 53. A portion of the contact member 60 may be in contact with air through the hole 53. In this way, the housing 50 has at least one hole 53, and a portion of the contact member 60 is exposed through the hole 53. For example, the housing 50 has at least one hole 53, and a portion of the middle root member is exposed through the hole 53. The hole 53 is formed, for example, in the lateral direction of the tubular portion 51 along the y-axis direction.

[0107] The housing 50 may have a plurality of holes 53. The plurality of holes 53 may be opposite to each other, with the central axis of the contact 60 disposed therebetween. Thus, the coaxial connector device 1 can make the impedance of the components opposite to each other across the central axis of the contact 60 uniform. For example, when the middle root component of the first rod-shaped portion 61 includes a square rod-shaped portion, a portion of the opposite flat side surfaces may be exposed through the plurality of holes 53. When the middle root component of the first rod-shaped portion 61 includes a round rod-shaped portion, a portion of the opposite curved side surfaces may be exposed through the plurality of holes 53.

[0108] The plurality of holes 53 may be a pair of holes facing each other across the central axis of the contact 60, or may be a plurality of pairs of holes facing each other across the central axis of the contact 60. The plurality of holes 53 may be discretely formed around the central axis. The plurality of holes 53 may be formed by using a holding member that supports the contact 60 during insert molding.

[0109] The support portion 52 is connected to the +x-axis side of the tubular portion 51. The support portion 52 is in the shape of a plate extending in the z-axis direction, and has plate surfaces on the +x-axis side and the -x-axis side. The tubular portion 51 is connected to the +z-axis side of the plate surface on the -x-axis side of the support portion 52. Therefore, when viewed from the y-axis direction, the housing 50 is L-shaped.

[0110] The housing 50 includes an insulator as a material. For example, the housing 50 includes a resin as a material. In addition, the housing 50 may include an insulator other than a resin, as long as it includes an insulator.

[0111] <Assembly Method>

[0112] The contact unit 70 is inserted into the through hole 24 of the die casting 20 along the -x-axis direction. The tubular portion 51 extending along the x-axis direction in the housing 50 is arranged between the first rod-shaped portion 61 extending along the x-axis direction in the contact member 60 and the die casting 20. The L-shaped portion 12 and the L-shaped portion 13 of the outer shell 10 are engaged with the L-shaped groove 22 and the L-shaped groove 23 of the die casting 20. The covering portion 32 and the covering portion 33 cover the L-shaped portion 12 and the L-shaped portion 13 from the side, respectively. The recess 12c and the recess 13c are respectively assembled to the assembly portion 32a and the assembly portion 33a. A component such as the contact unit 70 is inserted into the through hole 14 of the outer shell 10 and the through hole 24 of the die casting 20.

[0113] The beneficial effects of this embodiment are described below. In the coaxial connector device 1 according to this embodiment, the outer shell 10 includes the L-shaped portion 12, etc., and the die-casting 20 includes the L-shaped groove 22, etc. In the coaxial connector device 1, the L-shaped portion 12, etc. and the L-shaped groove 22, etc. are interlocked with each other, whereby the surface 19 of the -x-axis direction side of the second extension portion 12b contacts the surface 29 of the second groove portion 22b facing the +x-axis direction. In this way, the surface 19 of the outer shell 10 and the surface 29 of the die-casting 20 face a direction perpendicular to the specific substrate, thereby bearing a force from the x-axis direction (for example, the horizontal direction).

[0114] As described above, because the coaxial connector device 1 has a structure that "locks" the L-shaped portion 12 and the like with the L-shaped groove 22 and the like, the holding force of the outer shell 10 and the die casting 20 in the x-axis direction is improved. Therefore, the connection reliability of the coaxial connector device 1 is improved. Specifically, this helps to hold in the x-axis direction until the surface 19 of the outer shell 10 and the surface 29 of the die casting 20 are damaged.

[0115] In addition, in the coaxial connector device 1 according to the present embodiment, the covering portion 32 etc. covers the L-shaped portion 12 etc., and the fitting portion 32a etc. fits into the recessed portion 12c etc. of the L-shaped portion 12 etc. In this structure, the shield shell 30 of the coaxial connector device 1 covers the L-shaped portion 12 etc. of the outer shell 10, and reduces the displacement of the L-shaped portion 12 etc. in the z-axis direction. Therefore, the connection reliability can be further improved.

[0116] Although the embodiments of the present invention have been described above, the present invention includes appropriate modifications that do not deviate from the object and advantages thereof, and the present invention is not limited to the above-described embodiments. In addition, the structures of the comparative example and the first embodiment may be appropriately combined.

[0117] According to the disclosure of this specification, it is obvious that the embodiment of the present case can be changed in many ways. Such changes should not be regarded as departing from the spirit and scope of the present case, and all such modifications obvious to those skilled in the art are intended to be included in the scope of the appended claims.
