Description

Technical Field

[0002] Recent in-vehicle coaxial connector devices need to transmit high-frequency signals. Therefore, in the design of coaxial connector devices that transmit high-frequency signals, it is necessary to more effectively adjust impedance matching.

[0003] like Fig.17 As shown, Japanese unexamined patent application publication No. 2022-189573 discloses a connector in which the contact is, for example, press-fitted into a housing. In order to optimize manufacturing performance, this type of vehicle-mounted coaxial connector is generally designed as a structure in which the contact is press-fitted into the housing. However, in the structure in which the contact is press-fitted into the housing, in order to prevent the contact from coming out of the housing, it is necessary to provide tiny bumps on the surface of the contact. As a result, the high-frequency signal transmitted through the contact will be affected by these bumps. This makes it difficult for the vehicle-mounted coaxial connector to improve the matching with the designed impedance. Summary of the invention

[0038] 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. In addition, 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.

[0039] <Outer shell>

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] <Die castings>

[0045] 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 located therebetween.

[0046] 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.

[0047] The die casting 120 has a through hole 124 extending from the end face of the main body 121 on the -x-axis direction to the end face of the main body 121 on the +x-axis direction. 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 portions where the interlocking plate 122a and the interlocking plate 122b are connected to each other in the end face on the -x-axis direction of the main body 121. The GND shell 140, the inner shell 150, the contact 160 and other components are used to be inserted into the through hole 124.

[0048] The die casting 120 includes a conductor as a material. For example, the die casting 120 may include metals such as aluminum and zinc as the material. The die casting 120 may be manufactured by die casting. It should be noted that the die casting 120 is not limited to being manufactured by die casting, and it may include a component manufactured by other processes such as casting or a 3D printer, or may include a shell component equivalent to the die casting. The die casting 120 is electrically connected to a ground potential (GND) together with the shielding shell 130. A connection structure for connecting to a specific substrate may be formed on the -z-axis side of the die casting 120.

[0049] <Shielding case>

[0050] The shielding case 130 includes a plate-shaped portion 131 and a spring-shaped portion 132. The plate-shaped portion 131 has a plate surface on the +x-axis direction side and a plate surface on the -x-axis direction side. The plate-shaped portion 131 has a through hole 134 penetrating the plate surface. The through hole 134 is provided with its central axis along the x-axis direction. The spring-shaped portion 132 is connected to the end portion on the +z-axis direction side of the plate-shaped portion 131. The spring-shaped portion 132 is, for example, plate-shaped. The spring-shaped portion 132 is arranged in such a manner that its plate surface is inclined with respect to the XY plane. The spring-shaped portion 132 has spring elasticity. The spring-shaped portion 132 can be bent along the z-axis direction.

[0051] The plate-shaped portion 131 is provided on the end surface on the -x-axis direction side of the main body portion 121 of the die-cast part 120. Therefore, the plate-shaped portion 131 is provided between the fitting plate 122a and the fitting plate 122b. The through hole 134 of the plate-shaped portion 131 is provided to surround the through hole 124. The insertion portion 112 of the outer housing 110 is provided on the -x-axis direction side of the plate-shaped portion 131. The spring-shaped portion 132 is provided on the upper surface of the main body portion 121 of the die-cast part 120.

[0052] The shielding case 130 contains a conductor as a material. For example, the shielding case 130 contains metal as a material. The shielding case 130 is electrically connected to the ground potential (GND) together with the die-cast part 120.

[0053] <GND case>

[0054] The GND case 140 has, for example, a tubular shape and has a through hole 144 penetrating along the x-axis direction. The through hole 144 is provided with its central axis along the x-axis direction. The GND case 140 has, for example, a cylindrical shape. The GND case 140 is provided in the through holes 114, 134, and 124 that are coaxially sleeved and communicated along the x-axis direction of the outer housing 110, the plate-shaped portion 131, and the die-cast part 120. The inner housing 150 press-fitted with the contact member 160 is inserted into the GND case 140.

[0055] The GND case 140 contains a conductor as a material. For example, the GND case 140 contains metal as a material. The GND case 140 is electrically connected to the ground potential (GND) together with the die-cast part 120 and the shielding case 130.

[0056] <Inner housing>

[0057] The inner shell 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 a cylindrical shape. 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 penetrates 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.

[0058] 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 of the plate surface on the -x-axis side of the support portion 152 on the +z-axis side. 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 be fitted may 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.

[0059] The inner case 150 includes an insulator as a material. For example, the inner case 150 includes a resin as a material. It should be noted that the inner case 150 may also include an insulator other than a resin, as long as it includes an insulator.

[0060] <Contact>

[0061] Figure 2 1 is a side view showing a contact 160 in a coaxial connector device 101 according to a comparative example. Figure 3 1 is a partially enlarged view showing a contact 160 in a coaxial connector device 101 according to a comparative example. Figure 4 is a partial perspective view showing a contact 160 in a coaxial connector device 101 according to a comparative example.

[0062] like Figures 2 to 4As shown, 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. Although the first rod-shaped portion 161 and the second rod-shaped portion 162 of the contact member 160 are orthogonal to each other, they are not limited to this, and they can also intersect at an angle other than 90°. It should be noted that orthogonality is not limited to a strict 90° intersection, but also includes an intersection at 90° within a range that includes inevitable errors such as measurement errors.

[0063] The first rod-shaped portion 161, for example, includes a distal portion 161a, a middle portion 161b, and a root portion 161c. The distal portion 161a has a round rod shape. The distal end of the distal portion 161a is semi-spherical. The middle portion 161b is in a square rod shape. The width between the opposite sides of the square rod-shaped middle portion 161b is greater than the outer diameter of the round rod-shaped distal portion 161a. The middle portion 161b has a protrusion 163 on the -x axis side of each side on the +z axis side and the -z axis side. The middle portion 161b has a protrusion 164 on each side on the +y axis side and the -y axis side.

[0064] The root 161c is in a square rod shape. The width between the opposite sides of the square rod-shaped root 161c is larger than the outer diameter of the round rod-shaped distal end 161a. The root 161c has a protrusion 165 on each side of the +z axis direction side and the -z axis direction side. The protrusion 165 is inclined in a manner that the width along the z axis direction increases toward the +x axis direction side. The root 161c has a protrusion 166 on the side of the +y axis direction side and the -y axis direction side.

[0065] The first rod-shaped portion 161 in the contact 160 is press-fitted into the through hole 154 of the inner housing 150. The press-fitting process of this contact requires protrusions 163 to 166 for maintaining the press-fit. The protrusions 164 and 166 on the side surfaces of the +y-axis direction side and the -y-axis direction side are also referred to as dowel parts. The contact 160 can be formed by punching a metal plate into an L-shape. Therefore, the y-axis direction of the contact 160 is also referred to as the thickness direction. Therefore, the contact 160 requires a dowel part in the thickness direction so that it can be maintained in the inner housing 150 after the press-fit.

[0066] The second rod-shaped portion 162, for example, includes a distal portion 162a, an intermediate portion 162b, and a root portion 162c. The distal portion 162a has a round rod shape. The distal end of the distal portion 162a is semi-spherical. The distal portion 162a is connected to a specific substrate located on the -z axis direction side. The intermediate portion 162b is in a square rod shape. The width between the opposite sides of the square rod-shaped intermediate portion 162b is greater than the outer diameter of the round rod-shaped distal portion 162a. The root portion 162c is in a square rod shape. The root portion 162c has a push portion 167 on the side of the +x axis direction side, and the push portion 167 is used to push the contact member 160 when the contact member 160 is press-fitted into the inner housing 150.

[0067] The contact 160 includes a conductor as a material. For example, the contact 160 includes a metal as a material. The contact 160 serves as a transmission path for high-frequency signals. The distal end 161a of the first rod-shaped portion 161 in the contact 160 serves as a connection portion with another connector, and the distal end 162a of the second rod-shaped portion 162 is connected to a substrate connection portion.

[0068] <Assembly Method>

[0069] Figure 5 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 5 The outer shell 110 is omitted. Figure 5 As shown, the first rod-shaped portion 161 of the contact piece 160 is press-fitted into the through hole 154 of the inner housing 150 along the -x-axis direction. In this process, the side surfaces of the middle portion 162b and the root portion 162c of the second rod-shaped portion 162 of the contact piece 160 on the -x-axis direction side are engaged with the groove of the support portion 152 of the inner housing 150. The inner housing 150 press-fitted with the contact piece 160 is referred to as a contact unit 170. Therefore, the contact unit 170 includes the contact piece 160 and the inner housing 150.

[0070] 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.

[0071] The insertion portion 112 of the outer shell 110 is assembled between the fitting plate 122a and the fitting plate 122b of the die casting 120, with the shield shell 130 interposed therebetween. In this process, the protrusion 113 of the outer shell 110 is inserted into the insertion hole 123 of the die casting 120. The GND shell 140 including the inner shell 150 and the contact 160 is inserted into the through hole 114 of the outer shell 110.

[0072] <Problems in Comparative Example>

[0073] It is very important to improve the transmission characteristics of high-frequency signals in the coaxial connector device 101. As shown in the coaxial connector device 101 according to the comparative example, in the process of press-fitting the contact 160 into the through hole 154 of the inner housing 150, the contact 160 is required to have protrusions 163 to 166 and a pressing portion 167. However, the protrusions 163 to 166 and the pressing portion 167 deteriorate the transmission characteristics of high-frequency signals. Therefore, it is difficult for the coaxial connector device 101 to improve impedance matching. In order to improve impedance matching, a method of keeping the contact 160 in the inner housing 150 without the protrusions 163 to 166 and the pressing portion 167 is required.

[0074] Figure 6 is a cross-sectional view showing a coaxial connector device 101 according to a comparative example, which shows Figure 5 Section along line VI-VI. Figure 7 is a partial enlarged view showing a coaxial connector device 101 according to a comparative example, showing Figure 6 Part VII of Figure 6 and Figure 7 As shown, there is an insulator of the inner housing 150 and a space around the contact 160. Therefore, the contact 160 includes a portion in contact with the insulator and a portion in contact with the metal. Since the dielectric constants of the portions in contact with the contact 160 are different from each other, it is necessary to adjust the sizes of the portion in contact with the insulator and the portion in contact with the metal so that the impedance of the contact 160 matches the designed impedance.

[0075] For example, in the contact member 160, the impedance of the portion in contact with the insulator is reduced. Therefore, when the impedance of the contact member 160 is low, the width of the contact member 160 in the z-axis direction is narrowed to make the portion in contact with the insulator smaller. Thus, the impedance of the contact member 160 is increased. On the other hand, the impedance of the portion in contact with the space will increase. Therefore, when the impedance of the contact member 160 is high, the width of the contact member 160 in the z-axis direction is increased to increase the portion in contact with the insulator. Thus, the impedance of the contact member 160 is reduced.

[0076] In this way, due to manufacturing deviation, the components in contact with the contact 160 may vary, and the impedance may also vary. Even in this case, it is desirable to easily adjust the impedance matching of the contact 160.

[0077] <First Embodiment>

[0078] A coaxial connector device according to a first embodiment will be described below. Figure 8 1 is a perspective view showing each component included in the coaxial connector device 1 according to the first embodiment. Figure 8 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 .

[0079] <Outer shell>

[0080] 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 serve as an interlocking component interlocked with the die casting 20.

[0081] 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, 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.

[0082] 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 toward the +x-axis direction. The second extension portion 12b extends from the end of the first extension portion 12a on the +x-axis direction toward the +z-axis direction. A recess 12c is formed at the end of the first extension portion 12a on the -z-axis direction of the L-shaped portion 12.

[0083] 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 of 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.

[0084] 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.

[0085] The "L" shape of the L-shaped portion 12 and the L-shaped portion 13 may also be reversed in the z-axis direction. Specifically, the second extension portion 12b may 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 may 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 may 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.

[0086] 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 direction side and the +y-axis direction side of the end surface on the -x-axis direction side of the main body portion 21 of the die casting 20. In addition, according to the directions 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.

[0087] The outer shell 10 includes an insulator as a material. For example, the outer shell 10 includes a resin as a material. It should be noted that the outer shell 10 may also include an insulator other than a resin as long as it includes an insulator.

[0088] <Die castings>

[0089] 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 is used to be inserted into the through hole 24.

[0090] 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 serve as fitting parts for fitting with the outer shell 10.

[0091] 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.

[0092] 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.

[0093] 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 groove 22 and the L-shaped groove 2 may also 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 of the first groove portion 22a on the +x-axis direction side to the -z-axis direction. Furthermore, the second groove portion 23b may also extend from the end portion of the first groove portion 23a on the +x-axis direction side to the -z-axis direction.

[0094] 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 and 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.

[0095] 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.

[0096] Then, after the second extension portion 12b is inserted into the first groove portion 22a along the +x-axis direction, 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, after 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, the second extension portion 23b of the L-shaped groove 23 is inserted into the +z-axis direction.

[0097] As such, the L-shaped portion 12 of the outer shell 10 is formed so that the L-shaped portion 12 is inserted into the L-shaped groove 22 of the die casting 20. Further, the L-shaped portion 13 of the outer shell 10 is formed so that the L-shaped portion 13 is inserted into the L-shaped groove 23 of the die casting 20.

[0098] When the L-shaped portion 12 of the outer housing 10 is inserted into the L-shaped groove 22 of the die casting 20, the surface 19 on the -x-axis direction side of the second extension portion 12b of the L-shaped portion 12 contacts the surface 29 of the second groove portion 22b in the L-shaped groove 22 that faces the +x-axis direction. When the L-shaped portion 13 of the outer housing 10 is inserted into the L-shaped groove 23 of the die casting 20, the surface 19 on the -x-axis direction side of the second extension portion 13b of the L-shaped portion 13 contacts the surface 29 of the second groove portion 23b of the L-shaped groove 23 that faces 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.

[0099] 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 include a component manufactured by other processes such as casting, 3D printer, etc., or may include a shell component equivalent to the die casting. The die casting 20 is electrically connected to the ground potential (GND) together with the shielding shell 30.

[0100] <Shielding case>

[0101] 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 in which 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.

[0102] 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 along the y-axis direction. The covering portion 32 extends from the end of the main body 31 on the -y-axis direction in the y-axis direction in 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 covering portion 32 on the -z-axis direction side. 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.

[0103] The covering portion 33 extends from the end portion on the +y-axis side in the y-axis direction of the main body portion 31 in 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.

[0104] 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.

[0105] 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 .

[0106] <Contact element>

[0107] Fig. 9 : is a side view showing the contact unit 70 in the coaxial connector device 1 according to the first embodiment. Fig.10 is a cross-sectional view showing a contact unit 70 in the coaxial connector device 1 according to the first embodiment, showing a cross-sectional view along Fig. 9 The section of line XX in . Fig.11 is a cross-sectional view showing a contact unit 70 in the coaxial connector device 1 according to the first embodiment, showing a cross-sectional view along Fig. 9 Section along line XI-XI in FIG. Fig.12 : is a side view showing the contact 60 in the coaxial connector device 1 according to the first embodiment. Fig.13: is a perspective view showing the contact 60 in the coaxial connector device 1 according to the first embodiment.

[0108] like Figures 9 to 13 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.

[0109] 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 the first rod-shaped portion 61, and the portion extending in the z-axis direction is referred to as the 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. Although the first rod-shaped portion 61 and the second rod-shaped portion 62 of the contact member 60 are orthogonal to each other, this is not limited to this, and they can also intersect at an angle other than 90°. It should be noted that orthogonality is not limited to a strict 90° intersection, but also includes an intersection at 90° within a range that includes unavoidable errors such as measurement errors.

[0110] 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 semi-spherical. 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. Sometimes the middle portion 61b and the root portion 61c are 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 round rod-shaped. Specifically, the first rod-shaped portion 61 may include a round rod-shaped portion.

[0111] 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 the end surface of the tubular portion 51 in the housing 50 on the -x-axis direction side.

[0112] The second rod-shaped portion 62, for example, has a distal portion 62a, a middle 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 middle 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 middle portion 62b and the root portion 62c are 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 middle 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 +x-axis direction side of the middle portion 62b.

[0113] Thus, the contact member 60 includes a distal end portion 61a protruding from the housing 50 and a central 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 central root member connected to the distal end portion 62a. At least a portion of the central root member is incorporated into the housing 50.

[0114] The contact 60 includes a conductor as a material. For example, the contact 60 includes a metal as a material. The contact 60 serves as a transmission path for high-frequency signals. The distal end 61a of the first rod-shaped portion 61 of the contact 60 serves as a connection portion with another connector, and the distal end 62a of the second rod-shaped portion 62 is connected to a substrate connection portion.

[0115] The housing 50 includes a tubular portion 51 and a supporting portion 52. The tubular portion 51 has, for example, a cylindrical shape. It should be noted that the tubular portion 51 is not limited to a cylindrical shape, as long as it is a cylindrical shape. The tubular portion 51 is arranged in such a manner that its central axis faces the x-axis direction. The tubular portion 51 in 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 tubular portion 51 is assembled with the middle portion 61b and the root portion 61c of the first rod-shaped portion 61 of the contact 60.

[0116] The tubular portion 51 has a hole 53 on its side. It should be noted that 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 through which a portion of the contact member 60 is exposed. For example, the housing 50 has at least one hole 53 through which a portion of the middle root member is exposed. The hole 53 is formed, for example, in the lateral direction of the tubular portion 51 along the y-axis direction.

[0117] The housing 50 may have a plurality of holes 53. The plurality of holes 53 may be formed so that the contact 60 is placed therebetween. For example, the plurality of holes 53 may also be opposite to each other and have the central axis of the contact 60 placed therebetween. Thus, the coaxial connector device 1 can make the impedance of the components between which the contact 60 is inserted uniform. This can also make the impedance of components that are opposite to each other across the central axis of the contact 60 uniform. For example, when the middle root part of the first rod-shaped portion 61 includes a square rod-shaped portion, a portion of the opposite flat side surfaces is exposed through the plurality of holes 53. When the middle root part 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.

[0118] 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 formed discretely around the central axis. The plurality of holes 53 are formed by using a retaining member 54 that supports the contact 60 during insert molding described later.

[0119] 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.

[0120] The housing 50 includes an insulator as a material. For example, the housing 50 includes a resin as a material. It should be noted that the housing 50 may also include an insulator other than a resin as long as it includes an insulator.

[0121] <Manufacturing method>

[0122] Next, a method for manufacturing the coaxial connector device 1 including a method for manufacturing the contact unit 70 is described. According to the method for manufacturing the coaxial connector device of this embodiment, the contact unit 70 including the contact 60 and the housing 50 encapsulating a portion of the contact 60 is formed by insert molding. Fig.14 FIG. 2 is a flowchart showing a method for manufacturing the contact unit 70 in the method for manufacturing the coaxial connector device 1 according to the first embodiment. Fig.14 As shown, the manufacturing method of the coaxial connector device 1 includes: step S11 of preparing the contact 60; step S12 of encapsulating a part of the contact 60 with an encapsulation material; and step S13 of curing the encapsulation material by insert molding to form the contact unit 70.

[0123] The step S11 of preparing the contact 60 may be performed by bending a rod-shaped member including a conductor to form the contact 60. Alternatively, the step S11 of preparing the contact 60 may be performed by cutting the contact 60 from a plate-shaped member including a conductor to form the contact 60.

[0124] The step S12 of encapsulating a portion of the contact 60 with an encapsulating material exposes the distal end portion 61a of the contact 60 from the encapsulating material. In addition, this step uses the encapsulating material to encapsulate the middle root member connected to the distal end portion 61a and at least one holding member 54 that contacts a portion of the middle root member and supports the contact 60.

[0125] Then, the retainer 54 is removed in step S13 of curing the encapsulation material by insert molding to form the contact unit 70. Therefore, the contact 60 includes a distal end portion 61a protruding from the housing 50, and a middle root member connected to the distal end portion 61a. Further, the housing 50 has at least one hole 53, and a portion of the middle root member is exposed in the hole 53.

[0126] <Assembly Method>

[0127] 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.

[0128] The beneficial effects of this embodiment are described below. According to the coaxial connector device 1 of this embodiment, the contact 60 and the housing 50 are integrated with the contact unit 70 by insert molding. Therefore, the coaxial connector device 1 does not have the press-fit structure used by the coaxial connector device 101 of the comparative example. Therefore, the coaxial connector device 1 does not require the protrusions 163 to 166 of the contact 160, thereby improving the transmission characteristics of high-frequency signals. Specifically, by adopting insert molding, the tiny bumps and recesses of the contact 60 are not required, thereby facilitating the adjustment of impedance. This can improve impedance matching.

[0129] In addition, by providing at least one retaining member 54 of the contact member 60 in insert molding, the hole 53 (formed by the retaining member 54) is provided at a position where the internal impedance of the insulator is reduced, which is also beneficial to the adjustment of impedance.

[0130] Fig.15 : is a graph showing the impedance of the contact 160 in the coaxial connector device 101 according to the comparative example, wherein the horizontal axis represents the position of the contact 160 and the vertical axis represents the impedance. Fig.16 : is a graph showing the impedance of the contact 60 in the coaxial connector device 1 according to the first embodiment, wherein the horizontal axis represents the position of the contact 60 and the vertical axis represents the impedance. Fig.15 and Fig.16 In FIG. 1 , a rising region where the impedance rises when the contact member 160 and the contact member 60 are in contact with the space is indicated by a dotted line, and a falling region where the impedance falls when the contact member 160 and the contact member 60 are in contact with the insulator is indicated by a solid line.

[0131] like Fig.15 As shown, in the coaxial connector device 101 according to the comparative example, the tubular portion 151 does not have the hole 53 that exposes the contact 160. In this case, the distal end portion 161a and the distal end portion 162a are in contact with the space, and the other parts are in contact with the insulator. Therefore, the contact 160 has three regions in sequence in the transmission path from the distal end portion 161a to the distal end portion 162a: a rising region, a falling region, and a rising region. In this case, there is a large difference in impedance between these regions. The signal integrity (SI) characteristic is therefore reduced.

[0132] On the other hand, Fig.16 As shown, in the coaxial connector device 1 according to the first embodiment, the tubular portion 51 has the hole 53, and the contact 60 is exposed through the hole 53. At this time, the distal end portion 61a, the root portion 61c and the distal end portion 62a are in contact with the space, and the other portions are in contact with the insulator. Therefore, the contact 60 has five regions of the rising region, the falling region, the rising region, the falling region and the rising region in the transmission path from the distal end portion 61a to the distal end portion 62a. In this case, the impedance difference between these regions is small. The signal integrity characteristics are thereby improved.

[0133] 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.

[0134] 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.
