Description

[Technical field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] Conventionally, there is known a connector as disclosed in Patent Document 1. This connector includes a housing base that is fixed to an object to which the connector is attached, a housing movable part that fits with an object to be connected, and an integrated spring body having an oscillating spring part. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-33832 A Summary of the Invention [Problem to be solved by the invention]

[0004] The above connector can also be understood as follows. That is, the connector includes a base (housing base and supporting and fixing portion) fixed to an attachment object, a movable portion (housing movable portion and floating fixed portion) configured to be movable relative to the base, and a relay portion (oscillating spring portion). The base includes a first base-side conductor portion (supporting and fixing portion), the movable portion includes a first movable-part-side conductor portion (floating fixed portion), and the relay portion includes a first relay conductor portion (oscillating spring portion) relaying the first base-side conductor portion and the first movable-part-side conductor portion. The deformation of the oscillating spring portion allows the housing movable portion to move relative to the housing base portion.

[0005] In the above connector, the shape of the deformed first relay conductor (oscillating spring part) varies depending on the direction and amount of movement of the movable part relative to the base. In particular, in recent high-speed transmission environments, the effect of differences in shape on transmission characteristics is significant, and the transmission characteristics may deteriorate depending on the deformed shape. For example, when the movable part is in a predetermined position, the high-speed transmission characteristics are excellent, but when the movable part is moved from the predetermined position, the transmission characteristics may deteriorate.

[0006] An object of the present disclosure is to provide a connector capable of suppressing degradation of transmission characteristics caused by deformation of a first relay conductor portion. [Means for solving the problem]

[0007] A connector according to a first aspect is a connector that is attached to an object to be attached and connected to an object to be connected, the connector comprising a base, a movable part configured to be movable relative to the base, and a relay part, the base comprising a first base-side conductor, the movable part comprising a first movable-part-side conductor, the relay part comprising a first relay conductor that relays the first base-side conductor and the first movable-part-side conductor, the first base-side conductor, the first relay conductor and the first movable-part-side conductor forming a first conductor part electrically connecting the object to be attached and the object to be connected, the first base-side conductor having a first base-side contact surface, the first movable-part-side conductor having a first movable-part-side contact surface, the first relay conductor having at least one first rotating conductor, and the first rotating conductor configured to be rotatable while maintaining contact with both the first base-side contact surface and the first movable-part-side contact surface when the movable part moves relative to the base.

[0008] In this aspect, the connector comprises a base, a movable part configured to be movable relative to the base, and a relay part. The base comprises a first base-side conductor. The movable part comprises a first movable-part-side conductor. The relay part comprises a first relay conductor that relays the first base-side conductor and the first movable-part-side conductor. The first base-side conductor, the first relay conductor, and the first movable-part-side conductor constitute a first conductor that electrically connects the attachment object and the connection object.

[0009] In this aspect, the first base-side conductor has a first base-side contact surface, the first movable-part-side conductor has a first movable-part-side contact surface, the first relay conductor has at least one first rotating conductor, and the first rotating conductor is configured to be rotatable while maintaining contact with both the first base-side contact surface and the first movable-part-side contact surface when the movable part moves relative to the base. Therefore, even when the movable portion moves relative to the base portion, the first relay conductor portion does not deform or only deforms to a small extent, thereby making it possible to suppress deterioration of the transmission characteristics caused by deformation of the first relay conductor portion.

[0010] In the embodiment described later, the position of the rotating conductor relative to the base conductor is fixed, so that even if the movable conductor moves relative to the fixed member, the position of the portion of the first fixed contact surface that contacts the rotating conductor does not move. Therefore, when the rotating conductor rotates, friction occurs between the surface of the rotating conductor and the first fixed contact surface. However, this embodiment is not limited to this. In the embodiment described later, the directions in which the movable part can move (first and second directions described later) are directions perpendicular to the connection direction with the connection object and parallel to the attachment surface of the attachment object. However, the directions in which the movable part can move in this embodiment are not limited to this. For example, the first and second directions do not have to be directions perpendicular to the connection direction and parallel to the attachment surface of the attachment object. In the embodiment described below, the rotating conductor is spherical, but the rotating conductor of this embodiment is not limited thereto and may be, for example, cylindrical or another shape. In the embodiment described later, the first base-side contact surface contacts the first rotating conductor from one side (upper side) in the connection direction, and the first movable-part-side contact surface contacts the first rotating conductor from the other side (lower side) in the connection direction. However, the direction in which the first base-side contact surface and the first movable-part-side contact surface contact the first rotating conductor in this embodiment are not limited to this. In the embodiment described below, the movable part is configured to be able to fit with a connection target, but the movable part of this aspect is not limited thereto.

[0011] The connector of the second aspect is the first aspect, wherein the base comprises a second base-side conductor, the movable part comprises a second movable part-side conductor, the relay part comprises a second relay conductor that relays the second base-side conductor and the second movable part-side conductor, the second base-side conductor, the second relay conductor and the second movable part-side conductor constitute a second conductor that electrically connects the attachment object and the connection object, the second conductor shields at least a portion of the first conductor, the second base-side conductor has a second base-side contact surface, the second movable part-side conductor has a second movable part-side contact surface, the second relay conductor has at least one second rotating conductor, and the second rotating conductor is configured to be rotatable while maintaining contact with both the second base-side contact surface and the second movable part-side contact surface when the movable part moves relative to the base.

[0012] In this aspect, the base includes a second base-side conductor. The movable part includes a second movable-part-side conductor. The relay part includes a second relay conductor that relays the second base-side conductor and the second movable-part-side conductor. The second base-side conductor, the second relay conductor, and the second movable-part-side conductor constitute a second conductor that electrically connects the attachment object and the connection object. Here, the second conductor shields at least a portion of the first conductor. Therefore, the second conductor portion can provide the connector with shielding performance.

[0013] In this embodiment, the second base-side conductor has a second base-side contact surface, the second movable-part-side conductor has a second movable-part-side contact surface, the second relay conductor has at least one second rotating conductor, and the second rotating conductor is configured to be rotatable while maintaining contact with both the second base-side contact surface and the second movable-part-side contact surface when the movable part moves relative to the base. Therefore, even if the movable portion moves relative to the base portion, the path provided by the second conductor portion can be maintained.

[0014] A third aspect of the connector is the same as the second aspect, in which the at least one second rotating conductor comprises three or more second rotating conductors, and the three or more second rotating conductors are arranged to surround the first conductor portion.

[0015] In this embodiment, the at least one second rotary conductor includes three or more second rotary conductors that are arranged to surround the first conductor portion. This allows the structure of the first relay conductor section and the second relay conductor section to approach a coaxial structure.

[0016] In the embodiment described below, the first conductor has only one first rotating conductor, but the first conductor of this embodiment is not limited to this. In the embodiment described later, three or more second rotating conductors are arranged on a plane along the first direction and the second direction. However, In the embodiment described below, three or more second rotating conductors are arranged on a circumference centered on the first relay conductor portion, but the present embodiment is not limited to this.

[0017] The connector of the fourth aspect is the connector of the second or third aspect, wherein the second conductor portion has a base-side shield portion that shields at least a portion of the first base-side conductor portion, and an adjustment member that adjusts the impedance of the first base-side conductor portion, and the distance of the adjustment member to the first base-side conductor portion is smaller than the distance of the base-side shield portion to the first base-side conductor portion.

[0018] In this aspect, the second conductor has a base side shield portion that shields at least a portion of the first base side conductor. This improves the shielding performance of the connector. In this aspect, the second conductor has an adjusting member for adjusting the impedance of the first base-side conductor, the distance of the adjusting member to the first base-side conductor being shorter than the distance of the base-side shield portion to the first base-side conductor. Therefore, the impedance of the first base side conductor can be adjusted by the structure of the adjustment member.

[0019] In the embodiment described below, the base-side shield part is realized by the second base-side conductor part and the second movable-part-side conductor part. However, the base-side shield part of this embodiment is not limited to this. The base-side shield part may be realized by only one of the second base-side conductor part and the second movable-part-side conductor part.

[0020] A connector according to a fifth aspect is any one of the first to fourth aspects, wherein the movable part is configured to be movable relative to the base in a first direction and a second direction that are perpendicular to each other, and the connector is provided with a biasing mechanism that biases the base and the movable part in a direction to bring them closer to each other in a third direction that is perpendicular to both the first direction and the second direction.

[0021] In this aspect, the movable portion is configured to be movable relative to the base portion in a first direction and a second direction that are perpendicular to each other. The connector includes a biasing mechanism that biases the base portion and the movable portion toward each other in a third direction that is perpendicular to both the first direction and the second direction. This makes it possible to reliably maintain the first rotating conductor in contact with both the first base side contact surface and the first movable part side contact surface.

[0022] A sixth aspect of the connector is, in any one of the second to fourth aspects, such that the movable part is configured to be movable relative to the base in a first direction and a second direction which are directions perpendicular to each other, the connector is provided with a biasing mechanism which biases the base and the movable part in a direction to bring them closer to each other in a third direction which is a direction perpendicular to both the first direction and the second direction, the second base side conductor is provided with a base side shell which shields at least a portion of the first conductor, the second movable part side conductor is provided with a movable part side shell which shields at least a portion of the first conductor, the base side shell has a base side engaging part, the movable part side shell has a movable part side engaging part, and the biasing mechanism is configured by the base side engaging part and the movable part side engaging part engaging with each other.

[0023] In this aspect, the second base side conductor includes a base side shell that shields at least a portion of the first conductor, and the second movable part side conductor includes a movable part side shell that shields at least a portion of the first conductor. This improves the shielding performance of the connector. In this aspect, the base shell has a base engagement portion, and the movable shell has a movable engagement portion. The biasing mechanism is formed by the base engagement portion and the movable engagement portion engaging with each other. Therefore, the number of parts can be reduced compared to when the biasing mechanism is realized by members other than the base-side shell and the movable-part-side shell. Also, the path between the second base-side conductor and the second movable-part-side conductor can be secured by the engagement of the base-side engaging portion and the movable-part-side engaging portion in addition to the second relay conductor.

[0024] In the embodiment described later, the base shell is connected to the attachment object by soldering or the like. This can prevent a stub from being formed in the second conductor. However, the base shell of this embodiment is not limited to this.

[0025] A connector according to a seventh aspect is any one of the first to sixth aspects, wherein the connector is provided with a return mechanism, and when the movable part is displaced relative to the base in a direction within a plane along a first direction and a second direction, the return mechanism applies a force to the movable part in a direction opposite to the direction of displacement.

[0026] In this aspect, the connector includes a return mechanism that applies a force to the movable part in a direction opposite to the direction of displacement when the movable part is displaced relative to the base part in a direction within a plane along the first direction and the second direction. This allows the movable part to be returned to a predetermined position.

[0027] The connector of the eighth aspect is any of the second to fourth aspects, wherein the connector is provided with a return mechanism, and when the movable part is displaced relative to the base in a direction within a plane along a first direction and a second direction, the return mechanism applies a force to the movable part in a direction opposite to the direction of displacement, the second base side conductor comprises a base side shell that shields at least a portion of the first conductor, the second movable part side conductor comprises a movable part side shell that shields at least a portion of the first conductor, the base side shell has a base side engaging portion, and the movable part side shell has a movable part side engaging portion, and the return mechanism is configured by the base side engaging portion and the movable part side engaging portion engaging with each other.

[0028] In this aspect, the second base side conductor includes a base side shell that shields at least a portion of the first conductor, and the second movable part side conductor includes a movable part side shell that shields at least a portion of the first conductor. This improves the shielding performance of the connector. In this aspect, the base shell has a base engagement portion, and the movable shell has a movable engagement portion. The return mechanism is formed by the base engagement portion and the movable engagement portion engaging with each other. Therefore, the number of parts can be reduced compared to when the return mechanism is realized by members other than the base-side shell and the movable-part-side shell. Also, the path between the second base-side conductor and the second movable-part-side conductor can be secured by the engagement of the base-side engaging portion and the movable-part-side engaging portion in addition to the second relay conductor.

[0029] A ninth aspect of the connector is a connector in any one of the first to eighth aspects, the connector comprising a retaining member that holds the at least one first rotating conductor, the retaining member having a first accommodating space in which the first rotating conductor is accommodated.

[0030] In this aspect, the connector includes a holding member for holding at least one first rotating conductor, The holding member has a first receiving space for receiving the first rotating conductor. Therefore, the movement of the first rotating conductor can be limited to a predetermined range.

[0031] A connector according to a tenth aspect is any of the second to fourth aspects, wherein the connector comprises a retaining member that holds at least one first rotating conductor, the retaining member having a first accommodating space in which the first rotating conductor is accommodated, a second accommodating space in which the second rotating conductor is accommodated, and an adjustment space for adjusting the impedance of the first conductor portion.

[0032] In this aspect, the connector includes a holding member for holding at least one first rotating conductor, the holding member having a first housing space for housing the first rotating conductor and a second housing space for housing the second rotating conductor. Therefore, the movement of the first rotating conductor and the second rotating conductor can be limited within a predetermined range, and the first rotating conductor and the second rotating conductor can be insulated from each other. In this embodiment, the holding member has an adjustment space for adjusting the impedance of the first conductor portion. Therefore, the impedance of the first conductor can be adjusted by changing the structure of the holding member.

[0033] The connector according to an eleventh aspect is any one of the first to tenth aspects, wherein the movable portion is configured to be rotatable with respect to the base portion.

[0034] In this aspect, the movable portion is configured to be rotatable relative to the base portion. This allows the object to be connected to rotate relative to the object to which it is attached.

[0035] In the embodiment described below, the main components of the connector have a rotationally symmetric structure. Therefore, even if the movable part rotates with respect to the base part, the effect on the transmission characteristics is small. However, the connector of this aspect is not limited to this.

[0036] A connector according to a twelfth aspect is any one of the second to fourth aspects, wherein the first rotating conductor and the second rotating conductor have the same shape.

[0037] In this embodiment, the first rotary conductor and the second rotary conductor have the same shape. Therefore, there is less need to distinguish between the first rotating conductor and the second rotating conductor during manufacturing, making manufacturing easier.

[0038] The connector of the thirteenth aspect is any one of the second to fourth aspects, in which the distance between the first base side contact surface and the first movable part side contact surface is smaller than the distance between the second base side contact surface and the second movable part side contact surface.

[0039] In this aspect, the distance between the first base side contact surface and the first movable part side contact surface is smaller than the distance between the second base side contact surface and the second movable part side contact surface. This makes it easier to improve the transmission characteristics of the connector.

[0040] The connector of the 14th aspect is any one of the second to fourth aspects, wherein the second movable part side conductor has a movable part side shell that shields at least a portion of the first conductor, and the movable part side shell has a movable part side shield part that shields at least a portion of the first movable part side conductor, and a relay part side shield part that shields at least a portion of the first relay conductor.

[0041] In this aspect, the second movable part side conductor has a movable part side shell that shields at least a part of the first conductor.

Therefore, the first movable part side conductor portion can be shielded by the structure of the movable part side shell. In this embodiment, the movable part side shell has the relay part side shield part that shields at least a part of the first relay conductor part. Therefore, even if the second base side conductor does not have a base side shell or the base side shell does not shield the first relay conductor, the first relay conductor can be appropriately shielded.

[0042] In the embodiment described below, the second base side conductor has a base side shell, but the second base side conductor of this aspect is not limited thereto. In the embodiment described below, the movable part shell has a base side shield part that shields at least a part of the first base side conductor part, but the movable part shell of this embodiment is not limited to this.

[0043] The connector of the 15th aspect is the 14th aspect, wherein the movable part side shell has a connecting portion that connects the movable part side shield portion and the relay part side shield portion, and the connecting portion has the second movable part side contact surface.

A plurality of second accommodating spaces 92 are formed. The first housing space 91 is a space that passes through the holding member 90 in the Z direction, and is a cylindrical space. The second housing space 92 is a space that passes through the holding member 90 in the Z direction, and is a cylindrical space. The second accommodation space 92 has the same shape as the first accommodation space 91 . Hereinafter, when there is no need to distinguish between the first accommodation space 91 and the second accommodation space 92, they will simply be referred to as accommodation spaces 91, 92.

[0072] The accommodation spaces 91, 92 permit rotation of the rotating conductors 81A, 82A, while restricting the movement of the rotating conductors 81A, 82A. Specifically, the diameter of the accommodating spaces 91, 92 is the same as or slightly larger than the diameter of the rotating conductors 81A, 82A. By making the diameter of the accommodating spaces 91, 92 slightly larger than the diameter of the rotating conductors 81A, 82A, it is possible to prevent a situation in which the rotating conductors 81A, 82A cannot be accommodated in the accommodating spaces 91, 92 due to the influence of manufacturing tolerances. In addition, it is possible to suppress the generation of abnormal noise caused by the rotating conductors 81A, 82A moving within the accommodating spaces 91, 92.

[0073] However, the diameter of the accommodation spaces 91, 92 may be 1.1 times or more (or even 1.2 times or more) the diameter of the rotating conductors 81A, 82A. This allows the contact positions of the base-side contact surfaces 31a and 43a with the rotating conductors 81A and 82A to be moved, thereby preventing the first base-side contact surface 31a or the second base-side contact surface 43a from being scraped or otherwise damaged by friction.

[0074] The holding member has a plurality of adjustment spaces 93. The adjustment spaces 93 are provided to adjust the impedance of the first conductor parts 21, 81, and 51. The number of the plurality of adjustment spaces 93 is the same as the number of the second accommodating spaces 92. The adjustment space 93 is a space that passes through the holding member 90 in the Z direction, and is a cylindrical space. The adjustment space 93 is smaller than the first accommodating space 91 . The circumferential positions at which the plurality of adjustment spaces 93 are provided are different from the circumferential positions at which the plurality of second accommodating spaces 92 are provided. Specifically, the adjustment spaces 93 and the second accommodating spaces 92 are provided alternately along the circumferential direction. The distance of the multiple adjustment spaces 93 from the first accommodating space 91 is smaller than the distance of the multiple second accommodating spaces 92 from the first accommodating space 91. In other words, the multiple adjustment spaces 93 are located radially inward of the multiple second accommodating spaces 92.

[0075] The holding member 90 has a plurality of protrusions 94. The plurality of protrusions 94 are composed of a plurality of protrusions 94 protruding upward and a plurality of protrusions 94 protruding downward. This gives the holding member 90 a top-to-bottom symmetrical shape. Therefore, even if the holding member 90 is placed upside down, the connector 100 can be assembled without any problems. The multiple protrusions 94 protruding downward are inserted into the multiple second through holes 43c of the contact conductor 43. In this way, the holding member 90 constitutes a part of the base 11, and the holding member 90 is configured not to move relative to the attachment object 100. The multiple protruding portions 94 protruding upward face the connecting portion 74 of the movable part shell 70 in the up-down direction. Although it cannot be seen in the figure, the multiple protruding portions 94 protruding upward form a small gap with the underside of the connecting portion 74 of the movable part shell 70. The circumferential positions at which the multiple protrusions 94 are provided are the same as the circumferential positions at which the multiple adjustment spaces 93 are provided.

[0076] <Action and effect> Next, the effects of this embodiment will be described.

[0077] In this embodiment, as shown in Figures 4 and 5, the connector 10 includes a base 11, a movable part 12 configured to be movable relative to the base 11, and a relay part 13. The base 11 includes a first base-side conductor 21. The movable part 12 includes a first movable-part-side conductor 51. The relay part 13 includes a first relay conductor 81 that relays the first base-side conductor 21 and the first movable-part-side conductor 51. The first base-side conductor 21, the first relay conductor 81, and the first movable-part-side conductor 51 configure first conductors 21, 81, 51 that electrically connect the attachment object 100 and the connection object (not shown).

[0078] 4, in this embodiment, the first base-side conductor 21 has a first base-side contact surface 31a, and the first movable-part-side conductor 51 has a first movable-part-side contact surface 61a. The first relay conductor 81 has at least one first rotating conductor 81A. The first rotating conductor 81A is configured to be rotatable while maintaining contact with both the first base-side contact surface 31a and the first movable-part-side contact surface 61a when the movable part 12 moves relative to the base 11. For this reason, even when the movable part 12 moves relative to the base part 11, the first relay conductor part 81 does not deform or only deforms to a small extent. Therefore, deterioration of the transmission characteristics caused by the deformation of the first relay conductor part 81 can be suppressed.

[0079] 4, in this embodiment, the base 11 includes a second base-side conductor 22. The movable part 12 includes a second movable part-side conductor 52. The relay part 13 includes a second relay conductor 82 that relays the second base-side conductor 22 and the second movable part-side conductor 52. The second base-side conductor 22, the second relay conductor 82, and the second movable part-side conductor 52 configure second conductors 22, 82, 52 that electrically connect the attachment object 100 and the connection object (not shown). Here, the second conductors 22, 82, and 52 shield at least a part of the first conductors 21, 81, and 51. Therefore, the second conductors 22, 82, and 52 can provide the connector 10 with shielding performance.

[0080] 4, in this embodiment, the second base-side conductor 22 has a second base-side contact surface 43a, and the second movable-part-side conductor 52 has a second movable-part-side contact surface 74a. The second relay conductor 82 has at least one second rotating conductor 82A. The second rotating conductor 82A is configured to be rotatable while maintaining contact with both the second base-side contact surface 43a and the second movable-part-side contact surface 74a when the movable part 12 moves relative to the base 11. Therefore, even when the movable part 12 moves relative to the base part 11, the path through the second conductor parts 22, 82, and 52 can be maintained.

[0081] 5, at least one second rotating conductor 82A includes three or more second rotating conductors 82A. The three or more second rotating conductors 82A are arranged so as to surround the first conductors 21, 81, and 51. Therefore, the structure of the first relay conductor part 81 and the second relay conductor part 82 can be made closer to a coaxial structure.

[0082] In the present embodiment, the second conductors 22, 82, 52 have base side shield parts 41, 73 that shield at least a part of the first base side conductor 21, as shown in FIG. This makes it possible to improve the shielding performance of the connector 10. 5 , the second conductors 22, 82, 52 have an adjusting member 42 that adjusts the impedance of the first base-side conductor 21. The distance of the adjusting member 42 to the first base-side conductor 21 is smaller than the distance of the base-side shield parts 41, 73 to the first base-side conductor 21. Therefore, the impedance of the first base side conductor 21 can be adjusted by the structure of the adjusting member 42.

[0083] In this embodiment, the movable portion 12 is configured to be movable with respect to the base portion 11 in a first direction (±X directions) and a second direction (±Y directions) that are perpendicular to each other. 2 and 3, the connector 10 includes biasing mechanisms 41b and 73b. The biasing mechanisms 41b and 73b bias the base 11 and the movable part 12 in a direction to move them closer to each other in a third direction (±Z direction) perpendicular to both the first direction (±X direction) and the second direction (±Y direction). Therefore, the first rotating conductor 81A can be reliably maintained in a state in which it is in contact with both the first base portion side contact surface 31a and the first movable portion side contact surface 61a.

[0084] 2 and 3 , in this embodiment, the second base-side conductor 22 includes a base-side shell 41 that shields at least a portion of the first conductors 21, 81, 51. The second movable-part-side conductor 52 includes a movable-part-side shell 70 that shields at least a portion of the first conductors 21, 81, 51. This makes it possible to improve the shielding performance of the connector 10. In this embodiment, the base shell 41 has a base engaging portion 41b, and the movable shell 70 has a movable engaging portion 73b. The biasing mechanisms 41b and 73b are configured by the base engaging portion 41b and the movable engaging portion 73b engaging with each other. For this reason, the number of parts can be reduced compared to a case in which the biasing mechanisms 41b, 73b are realized by members other than the base-side shell 41 and the movable-part-side shell 70. Also, the path between the second base-side conductor 22 and the second movable-part-side conductor 52 can be secured not only by the second relay conductor 82, but also by the engagement of the base-side engaging portion 41b and the movable-part-side engaging portion 73b.

[0085] In this embodiment, the base shell 41 is connected to the attachment object 100 by soldering or the like. This makes it possible to prevent stubs from being formed in the second conductors 22, 82, and 52.

[0086] 2 and 3, the connector 10 includes return mechanisms 41b and 73b. When the movable part 12 is displaced relative to the base 11 in a direction within a plane (XY plane) along the first direction (±X directions) and the second direction (±Y directions), the return mechanisms 41b and 73b apply a force to the movable part 12 in a direction opposite to the direction of displacement. Therefore, the movable part 12 can be returned to a predetermined position.

[0087] As shown in Figs. 2 and 3, the return mechanisms 41b and 73b are configured by the base-side engaging portion 41b and the movable-side engaging portion 73b engaging with each other. For this reason, the number of parts can be reduced compared to a case in which the return mechanisms 41b, 73b are realized by members other than the base-side shell 41 and the movable-part-side shell 70. Also, the path between the second base-side conductor 22 and the second movable-part-side conductor 52 can be secured not only by the second relay conductor 82, but also by the engagement of the base-side engaging portion 41b and the movable-part-side engaging portion 73b.

[0088] 2 and 3, the connector 10 includes a holding member 90 that holds at least one first rotating conductor 81A and at least one second rotating conductor 82A. The holding member 90 has a first accommodating space 91 in which the first rotating conductor 81A is accommodated, and a second accommodating space 92 in which the second rotating conductor 82A is accommodated. Therefore, the movement of the first rotating conductor 81A and the second rotating conductor 82A can be limited to a predetermined range, and the first rotating conductor 81A and the second rotating conductor 82A can be insulated from each other. In this embodiment, the holding member 90 has an adjustment space 93 for adjusting the impedance of the first conductors 21, 81, and 51, as shown in FIG. Therefore, the impedance of the first conductors 21, 81, and 51 can be adjusted by changing the structure of the holding member 90.

[0089] In this embodiment, the movable portion 12 is configured to be rotatable with respect to the base portion 11 . Therefore, rotation of the connection object (not shown) relative to the attachment object 100 can be permitted. In particular, in this embodiment, the main components of the connector 10 have a rotationally symmetrical structure as shown in Fig. 5. Therefore, even if the movable part 12 rotates with respect to the base part 11, the effect on the transmission characteristics is small.

[0090] In this embodiment, as shown in FIG. 5, the first rotating conductor 81A and the second rotating conductor 82A have the same shape. Therefore, there is less need to distinguish between the first rotating conductor 81A and the second rotating conductor 82A during manufacturing, which makes manufacturing easier.

[0091] In this embodiment, the distance between the first base side contact surface 31a and the first movable part side contact surface 61a is the same as the distance between the second base side contact surface 43a and the second movable part side contact surface 74a. However, the distance between the first base side contact surface 31a and the first movable part side contact surface 61a may be smaller than the distance between the second base side contact surface 43a and the second movable part side contact surface 74a. In this case, the transmission characteristics of the connector can be easily improved.

[0092] 3, the second movable part side conductor 52 has a movable part side shell 70 that shields at least a part of the first conductors 21, 81, 51. The movable part side shell 70 has a movable part side shield part 71 that shields at least a part of the first movable part side conductor 51. Therefore, the first movable part side conductor 51 can be shielded by the structure of the movable part side shell 70. In this embodiment, the movable part side shell 70 has the relay part side shield part 72 that shields at least a part of the first relay conductor part 81 . Therefore, even if the second base side conductor portion 22 does not have a base side shell 41 or the base side shell 41 does not shield the first relay conductor portion 81, the first relay conductor portion 81 can be properly shielded.

[0093] In this embodiment, as shown in FIGS. 3 and 4, the movable part side shell 70 has a connecting portion 74 that connects the movable part side shield part 71 and the relay part side shield part 72 together. As shown in FIG. 4, the connecting portion 74 has a second movable portion side contact surface 74a. For this reason, the second movable part side contact surface 74a can be provided by utilizing the structure of the movable part side shell 70. As a result, an increase in the number of parts can be suppressed.

Then, a part or the whole of the second extending portion 32b is surface-mounted on a surface of a substrate as an attachment target 100. However, the first base-side terminal 30 of the present disclosure is not limited thereto, and may be mounted in a through-hole formed in a substrate. In this case, the extension 32 of the first base-side terminal 30 may have only the first extension 32a, and may not have the second extension 32b. In this case, the adjustment member 42 may be cylindrical.
