[0009] [Explanation of Embodiments of the Invention] First, an embodiment of the present invention will be explained.

[0010] The connector of the present invention is as follows.

[0011] (1) A connector provided with a terminal, and a counterpart terminal in the shape of a pin that is insertedly connected to the terminal, the connector being provided with: the terminal having a cylindrical base portion and a plurality of elastic pieces extending from one end of the cylindrical base portion; and a terminal housing member having a housing space that houses at least a portion of the terminal, the cylindrical base portion having a slit between the plurality of elastic pieces in the circumferential direction of the cylindrical base portion, the slit having a pair of side surfaces that face each other in the circumferential direction of the cylindrical base portion, the terminal housing member having a rotation-preventing protrusion that protrudes toward the housing space, is inserted into the slit, and is positioned between the pair of side surfaces.

[0012] According to this connector, the rotation-preventing protrusion is inserted into the slit of the cylindrical base portion in a state in which at least a portion of the terminal is housed in the housing space of the terminal housing member. By positioning the rotation-preventing protrusion between the pair of side surfaces, the terminal is restricted from rotating.

[0013] (2) In the connector of (1), it is also possible that, in the direction along the circumferential direction of the cylindrical base portion, the width of the slit is smaller than the width of the gap between the plurality of elastic pieces.

[0014] In this case, the slit and the rotation-preventing protrusion inserted into the slit are less likely to affect the elastic deformation of the plurality of elastic pieces.

[0015] ​​​(3) In the connector of (1) or (2), the cylindrical base can have a front stop face at a position different from the slit and between the plurality of elastic pieces in the circumferential direction of the cylindrical base, the front stop face facing the side where the plurality of elastic pieces each extend, and the terminal receiving member can have a front stop protrusion protruding toward the receiving space side opposite the front stop face.

[0016] In this case, the terminal is restricted from moving toward the tip end side by the front stop protrusion contacting the front stop face.

[0017] (4) In the connector of (3), the front stop protrusion can have a width greater than a width of the rotation stop protrusion in the direction along the circumferential direction of the cylindrical base.

[0018] Thus, the strength of the front stop protrusion that restricts the terminal from moving toward the tip end side can be increased.

[0019] (5) In the connector of (3) or (4), the rotation stop protrusion can be opposed to the inner side face of the slit via a gap on the side opposite the side where the plurality of elastic pieces each extend.

[0020] Thus, the force with which the terminal attempts to move toward the tip end side is received by the front stop protrusion. Therefore, the force applied to the rotation stop protrusion can be reduced, and the rotation stop protrusion can be reduced in size. Since the width of the slit can be made narrow, the strength of the cylindrical base can be increased.

[0021] (6) In the connector of any one of (3) to (5), the front stop protrusion can have a width less than a width of the gap between the plurality of elastic pieces in the direction along the circumferential direction of the cylindrical base.

[0022] Thus, the elastic pieces that elastically deform are less likely to interfere with the front stop protrusion.

[0023] (7) In the connector of any one of (1) to (6), the terminal receiving member can include a head portion that collectively covers the tip end portions of the plurality of elastic pieces, and a portion of the head portion can enter between the plurality of elastic pieces in the direction along the circumferential direction of the cylindrical base.

[0024] In this case, since a portion of the head portion of the terminal receiving member enters between the plurality of elastic pieces in the direction along the circumferential direction of the cylindrical base, the head portion can be made to approach the elastic pieces as much as possible. Thus, the elastic pieces can be easily protected.

[0025] (8) In the connector of (7), the pair of side faces can contact the rotation stop protrusion in a range where contact between any one of the plurality of elastic pieces and the head portion is avoided, and the terminal can be restricted from rotating.

[0026] Thus, deformation of the elastic pieces caused by contact of the elastic pieces and the head portion can be suppressed.

[0027] (9) In the connector of any one of (1) to (8), the end portion of the rotation-preventing protrusion on the side opposite to the direction in which each of the plurality of elastic pieces extends can be a tapered end portion that narrows in width toward the tip end.

[0028] Thus, it is easy to fit the rotation-preventing protrusion into the slit.

[0029] (10) In the connector of any one of (1) to (9), the connector can further include an outer conductor that surrounds the periphery of the terminal receiving member, and the terminal and the outer conductor can be arranged on the same axis.

[0030] Thus, the connector can be appropriately used as a coaxial connector. In this case, the terminal receiving member can be used as a dielectric body. Even in a case where the distance between the terminal receiving member and the inner conductor is reduced in order to increase the arrangement space of the dielectric body, the rotation of the terminal can be restricted, and thus the elastic pieces and the terminal receiving member are less likely to come into contact with each other, and deformation of the elastic pieces can be suppressed.

[0031] [Details of Embodiments of the Present Invention] Examples of the connector of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to these examples, and is shown by the claims, and is intended to include all modifications within the meaning and range equivalent to the claims.

[0032] [Embodiments] Hereinafter, the connector of the embodiments will be described. In the present embodiment, an example in which the connector is a coaxial connector will be described. In addition, an example in which the connector is a relay connector to be incorporated into an apparatus will be described. That is, in the present embodiment, an example in which the connector is a relay coaxial connector will be described.

[0033] Note that it is not necessary that the connector be a coaxial connector, the connector be incorporated into an apparatus, and the connector be a relay connector. For example, the connector can be a connector in which terminals are received in a housing, and can be a connector in which a plurality of terminals are not arranged on the same axis. In addition, the connector can be a connector to be fitted to the end portion of a cable, and can be a connector to be mounted to a substrate.

[0034] [Overall Structure of the Apparatus] An example of an apparatus 10 provided with a relay coaxial connector 40 will be described. Figure 1 is a perspective view showing the apparatus 10 provided with the relay coaxial connector 40. Figure 2 is a front view of the apparatus 10. Figure 1 is a II-II line sectional view of the apparatus 10.

[0035] The device 10 is, for example, a camera device. The camera device is, for example, a device for a vehicle. The device 10 can also be other than a camera device.

[0036] The device 10 includes a case 12 and an electrical component 20. The electrical component 20 is housed in the case 12. The electrical component 20 is fixed to a relay coaxial connector 40.

[0037] The case 12 includes a first case 13 and a second case 14. The first case 13 and the second case 14 are formed of resin, for example. The first case 13 and the second case 14 are combined to constitute the case 12 in the shape of a rectangular parallelepiped housing the electrical component 20. In the case where the device 10 is a camera device, the first case 13 is assumed to be a lens or a window for image pickup, and the second case 14 is assumed to have an external connection coaxial connector 30.

[0038] The external connection coaxial connector 30 is a coaxial connector for connecting the electrical component 20 and an electrical component outside. The external connection coaxial connector 30 is, for example, a coaxial connector to which a cable connected to an electrical component outside is connected. The cable connected to the external connection coaxial connector 30 is, for example, a coaxial cable.

[0039] More specifically, a holding cylinder portion 16 is provided protruding from a bottom portion 15 of the case 12. The holding cylinder portion 16 is a cylinder protruding outward from a central portion of the bottom portion 15. An inner side of the holding cylinder portion 16 is open in the second case 14, and an outer side of the holding cylinder portion 16 is open outside the second case 14. A holding partition portion 17 is formed in the holding cylinder portion 16 in a direction along a central axis X (axial direction X) thereof. In the present embodiment, the holding partition portion 17 is formed in the holding cylinder portion 16 at a position intermediate in the direction along the central axis X and closer to the inner side opening. The holding partition portion 17 separates a space on the inner side opening side and a space on the outer side opening side in the holding cylinder portion 16. A holding hole 17h is formed in the holding partition portion 17, and the external connection coaxial connector 30 is inserted and held in the holding hole 17h.

[0040] The external connection coaxial connector 30 includes an external connection inner conductor 32, an external connection insulator 34, and an external connection outer conductor 36.

[0041] The external connection inner conductor 32 is formed in an elongated rod shape and is formed of an electrically conductive material such as metal. The external connection inner conductor 32 is an example of a pin-shaped counterpart conductor that is inserted and connected to a movable-side inner conductor 42 described later. The external connection insulator 34 is formed of an insulator such as resin and surrounds the periphery of the external connection inner conductor 32. In the present embodiment, the external connection insulator 34 is a dielectric body. The external connection outer conductor 36 is formed of an electrically conductive material such as metal. The external connection outer conductor 36 is formed in a cylindrical shape that surrounds the periphery of the external connection insulator 34.

[0042] The electrical component 20 is, for example, a mounting substrate on which an electronic component is mounted. In the case where the apparatus 10 is a camera apparatus, the electrical component 20 is assumed to be a circuit substrate 21 and an image pickup element 22 mounted to the circuit substrate 21. The image pickup element 22 opposes a lens or a window for image pickup of the first housing 13, and rotates the lens or the window to perform image pickup of an outside scene. Hereinafter, the side of the first housing 13 toward which the image pickup element 22 faces is referred to as a front side, and the side of the second housing 14 opposite thereto is referred to as a rear side.

[0043] A substrate-side coaxial connector 60 is fixedly mounted to the circuit substrate 21. The substrate-side coaxial connector 60 is located on a side of the circuit substrate 21 opposite the image pickup element 22. The substrate-side coaxial connector 60 protrudes from the circuit substrate 21 toward the above-mentioned external connection coaxial connector 30. The substrate-side coaxial connector 60 has, for example, a substrate-side inner conductor 62, a substrate-side insulator 70, and a substrate-side outer conductor 80. The substrate-side inner conductor 62 and the substrate-side outer conductor 80 are connected to a circuit of the circuit substrate 21, for example, by soldering or the like. The substrate-side inner conductor 62 is connected to a movable-side inner conductor 42 described later. The substrate-side insulator 70 surrounds the periphery of the substrate-side inner conductor 62. The substrate-side outer conductor 80 surrounds the periphery of the substrate-side insulator 70. That is, the substrate-side inner conductor 62, the substrate-side insulator 70, and the substrate-side outer conductor 80 are arranged in a concentric circular shape from the center toward the periphery in this order.

[0044] The substrate-side coaxial connector 60 and the external connection coaxial connector 30 are connected via a relay coaxial connector 40. The relay coaxial connector 40 has, for example, a movable-side inner conductor 42, a movable-side insulator 50, and a movable-side outer conductor 56. The movable-side insulator 50 surrounds the periphery of the movable-side inner conductor 42. The movable-side insulator 50 can also be a dielectric body, which is one kind of insulator. The movable-side outer conductor 56 surrounds the periphery of the movable-side insulator 50.

[0045] The movable-side inner conductor 42 is an example of a terminal having a cylindrical base portion 43 and a plurality of elastic pieces 44 extending from one end of the cylindrical base portion 43, and is also an example of an inner conductor. The movable-side insulator 50 is an example of a terminal housing member having a housing space S, and houses at least a part of the movable-side inner conductor 42 as a terminal in the housing space S. The movable-side outer conductor 56 is an example of an outer conductor that surrounds the periphery of the movable-side insulator 50 as a terminal housing member. The movable-side inner conductor 42 and the movable-side outer conductor 56 are arranged coaxially.

[0046] In a state where the substrate-side inner conductor 62 is insertedly connected to the movable-side inner conductor 42 and the substrate-side outer conductor 80 is externally fittedly connected to the movable-side outer conductor 56, the relay coaxial connector 40 is connected to the substrate-side coaxial connector 60. In this state, the relay coaxial connector 40 further protrudes from the substrate-side coaxial connector 60 toward the external connection coaxial connector 30. By the external connection inner conductor 32 being insertedly connected to the movable-side inner conductor 42 and the movable-side outer conductor 56 being insertedly connected to the external connection outer conductor 36, the relay coaxial connector 40 is connected to the external connection coaxial connector 30. Thus, the relay coaxial connector 40 relays the connection of the substrate-side coaxial connector 60 and the external connection coaxial connector 30.

[0047] Thus, by the cable from the outside being connected to the external connection coaxial connector 30, the electrical component of the outside, which is the connection partner of the cable, and the electrical component 20 in the case 12 are electrically connected.

[0048] At the time of assembly work of the present apparatus 10 or in the completed state, the substrate-side coaxial connector 60 and the external connection coaxial connector 30 can be deviated from the positions opposed on the coaxial axis. In this case, the movable-side inner conductor 42 can be connected in a tilted state with respect to the substrate-side inner conductor 62 and the external connection inner conductor 32. Also, the movable-side outer conductor 56 can be insertedly connected in a tilted state with respect to the substrate-side outer conductor 80 and the external connection outer conductor 36. That is, the relay coaxial connector 40 can be connected in a tilted state with respect to the substrate-side coaxial connector 60 and the external connection coaxial connector. Thus, at the time of assembly work of the present apparatus 10 or in the completed state, even if the substrate-side coaxial connector 60 and the external connection coaxial connector 30 are deviated from the positions opposed on the coaxial axis, by the relay coaxial connector 40 being tilted with respect to the substrate-side coaxial connector 60 and the external connection coaxial connector, the misalignment is absorbed.

[0049] <About the Relay Coaxial Connector> The relay coaxial connector 40 will be described more specifically. Figure 3 is a sectional view of the relay coaxial connector 40 on the same section as Figure 2 Figure 4 is a sectional view of the relay coaxial connector 40 viewed from the side opposite to the sectional view of Figure 2 Figure 5 is a V-V line sectional view of Figure 3 Figure 6 is an exploded perspective view showing the relay coaxial connector 40. Figure 7 and Figure 8 are partial exploded perspective views of the relay coaxial connector 40. In Figure 7 , the movable-side insulator 50 is in the same shape as Figure 3 ​​​The movable-side insulator 50 is cut in the same plane as Figure 8 The movable-side insulator 50 is cut in the same plane as Figure 4 The movable-side insulator 50 is cut in the same plane as Figure 9 is a cross-sectional view taken along the IX-IX line of Figure 5 is a cross-sectional view taken along the X-X line of Figure 10 is a cross-sectional view taken along the X-X line of Figure 3 is a cross-sectional view taken along the X-X line of

[0050] As shown in FIG. 1, the coaxial connector 40 for relaying includes a movable-side inner conductor 42, a movable-side insulator 50, and a movable-side outer conductor 56. Figures 2 to 10 The movable-side inner conductor 42 is an elongated electrically conductive member. In the present embodiment, the movable-side inner conductor 42 is formed by press working a metal plate. More specifically, the movable-side inner conductor 42 includes a cylindrical base portion 43, a plurality of elastic pieces 44, and an opposite-side connecting portion 48.

[0051] The cylindrical base portion 43 is formed in a cylindrical shape, more specifically, a circular cylindrical shape. One end of the cylindrical base portion 43 faces the outer-connection inner conductor 32 side, and the other end of the cylindrical base portion 43 faces the substrate-side inner conductor 62 side.

[0052] A locking protrusion 43a can be provided protruding from the cylindrical base portion 43. The locking protrusion 43a partially protrudes from the outer peripheral portion of the cylindrical base portion 43. The locking protrusion 43a is formed in a shape in which the protruding dimension gradually increases from one end of the cylindrical base portion 43 toward the other end. In a state in which the cylindrical base portion 43 is inserted into the movable-side insulator 50, the locking protrusion 43a is hooked to the inner peripheral portion of the movable-side insulator 50, and the movable-side inner conductor 42 is held in a state in which it is prevented from coming off the movable-side insulator 50.

[0053] The cylindrical base portion 43 has a slit 43g between the plurality of elastic pieces 44 in the circumferential direction of the cylindrical base portion 43. The slit 43g is open at the one end side, the inner peripheral side, and the outer peripheral side of the cylindrical base portion 43. The slit 43g has a pair of side surfaces 43gl facing each other in the circumferential direction of the cylindrical base portion 43. The surface in the slit 43g that is on the other end side of the cylindrical base portion 43 and faces the one end of the cylindrical base portion 43 is a back surface 43g2.

[0054] In the present embodiment, a plurality of gaps exist between the plurality of elastic pieces 44, and the slit 43g exists in correspondence with a part of the plurality of gaps. More specifically, two gaps exist between two elastic pieces 44, and the slit 43g is provided in correspondence with one of the gaps. As will be described later, a rotation-preventing protrusion 53 formed in the inner peripheral portion of the movable-side insulator 50 can be fitted into this slit 43g. Thus, rotation of the movable-side inner conductor 42 relative to the movable-side insulator 50 is prevented. In addition, movement of the movable-side inner conductor 42 relative to the movable-side insulator 50 toward the tip end side is restricted.

[0055] ​

[0056] A plurality of elastic pieces 44 extend from one end of the cylindrical base 43. Preferably, the plurality of elastic pieces 44 are located at equal intervals around the central axis X of the cylindrical base 43. In the present embodiment, two elastic pieces 44 are opposed around the central axis X of the cylindrical base 43.

[0057] Each of the plurality of elastic pieces 44 has an elastic piece body 45 and an elastic contact piece 46.

[0058] The base end of the elastic piece body 45 is connected to one end of the cylindrical base 43. The elastic piece body 45 extends from one end of the cylindrical base 43 to one side in the axial direction X of the cylindrical base 43. The elastic contact piece 46 is an elastic contact piece that is folded back inward from the tip end of the elastic piece body 45 toward the base end of the elastic piece body 45.

[0059] The external connection inner conductor 32 is inserted from the tip end side of the two elastic pieces 44 toward between the two elastic pieces 44. By the external connection inner conductor 32 becoming sandwiched by the two elastic pieces 44, the movable side inner conductor 42 is connected to the external connection inner conductor 32.

[0060] Further, the elastic piece does not necessarily have the above-mentioned folded-back elastic contact piece, and the inward portion of the portion extending from the cylindrical base to one side in the axial direction X can also come into contact with the external connection inner conductor 32.

[0061] In the circumferential direction of the cylindrical base 43, there are gaps between the elastic piece bodies 45. At one end of the cylindrical base 43, there are two gaps between the two elastic pieces 44.

[0062] A slit 43g is formed in the portion of one end of the cylindrical base 43 corresponding to one of the gaps. A front stop face 43frs is formed in the portion of one end of the cylindrical base 43 corresponding to the other gap. The front stop face 43frs is located between the plurality of elastic pieces 44 in the circumferential direction of the cylindrical base 43 of the cylindrical base 43 and is different from the slit 43g. The front stop face 43frs is a face that extends toward the side of the elastic pieces 44. The front stop face 43frs is preferably orthogonal to the axial direction X.

[0063] By the front stop protrusion 54 of the movable side insulator 50 described later coming into contact with the front stop face 43frs, movement of the movable side insulator 50 to the side of the elastic pieces 44 is restricted.

[0064] The opposite side connecting portion 48 is connected to the cylindrical base 43 on the side opposite the plurality of elastic pieces 44. The opposite side connecting portion 48 is the portion to which the board side inner conductor 62 is connected. In the present embodiment, the opposite side connecting portion 48 is a cylindrical portion, more specifically, a cylindrical portion that is thicker than the cylindrical base 43. For example, the board side inner conductor 62 is inserted and connected to this opposite side connecting portion 48.

[0065] The movable-side insulator 50 is formed of resin or the like. The movable-side insulator 50 can be regarded as a dielectric body, and the dielectric body can be regarded as an insulator. The movable-side insulator 50 is, for example, a molded resin member.

[0066] The movable-side insulator 50 is formed in a cylindrical shape that can accommodate at least a portion of the movable-side inner conductor 42. In the present embodiment, the movable-side insulator 50 is formed in a circular cylindrical shape, and an accommodation space S is formed inside thereof. The cylindrical base portion 43 and the plurality of elastic pieces 44 of the movable-side inner conductor 42 are accommodated in the accommodation space S. The opposite-side connecting portion 48 protrudes to the outside of the movable-side insulator 50.

[0067] The movable-side insulator 50 has a cylindrical portion 51 and a head portion 52.

[0068] The cylindrical portion 51 is formed in a circular cylindrical shape. The cylindrical base portion 43 of the movable-side inner conductor 42 and portions of the plurality of elastic pieces 44 other than the tips are accommodated in the cylindrical portion 51. A rotation-preventing protrusion 53 protruding to the accommodation space S side is provided in the cylindrical portion 51. The rotation-preventing protrusion 53 is capable of being fitted into the slit 43g and positioned between the pair of side surfaces 43gl. Thus, rotation of the movable-side inner conductor 42 is prevented in the movable-side insulator 50.

[0069] In addition, the cylindrical portion 51 has a front stop protrusion 54 protruding to the accommodation space S side. The front stop protrusion 54 is disposed in opposition to the front stop surface 43frs. Thus, in the cylindrical portion 51, the movable-side inner conductor 42 is restricted from moving to the side in which the elastic pieces 44 are not extended.

[0070] The head portion 52 is an end portion of the movable-side insulator 50 located on the external-connection coaxial connector 30 side with respect to the cylindrical portion 51, and collectively covers the tip portions of the plurality of elastic pieces 44. A hole 52h communicating with the accommodation space S from the outside is formed in the head portion 52. The hole 52h is formed as a hole that is finer than the accommodation space S and into which the external-connection inner conductor 32 can be inserted. That is, the accommodation space S is reduced by the head portion 52. The hole 52h is in opposition to the tips of the plurality of elastic pieces 44, and blocks the periphery of the tip side of the plurality of elastic pieces 44. The position of the external-connection inner conductor 32 is restricted by the hole 52h, and thus the external-connection inner conductor 32 is easily disposed between the plurality of elastic pieces 44.

[0071] The portion of the inner side portion of the head 52 that is around the hole 52h and between the plurality of elastic pieces 44 protrudes more inward than other portions. The portion of the inner side portion of the head 52 that covers the tip end portions of the plurality of elastic pieces 44 is recessed in a manner that allows elastic deformation of the elastic pieces 44 in the inner-outer direction. The portion 52p of the inner side portion of the head 52 that is around the hole 52h and between the plurality of elastic pieces 44 enters between the plurality of elastic pieces 44 in a direction along the circumference of the cylindrical base 43. Thus, the space around the elastic pieces 44 can be used to house the dielectric body as much as possible.

[0072] Since the portion 52p of the head 52 enters between the tip end portions of the elastic pieces 44, when the movable-side inner conductor 42 is freely rotated, the tip end portions of the elastic pieces 44 can interfere with the portion 52p. The structure for stopping the rotation of the movable-side inner conductor 42 will be described later in detail.

[0073] The movable-side outer conductor 56 is disposed on the outer circumferential side of the movable-side insulator 50. The movable-side outer conductor 56 is formed of a conductive material such as metal and surrounds the periphery of the movable-side insulator 50. The movable-side outer conductor 56 is formed, for example, by press working a metal plate or the like.

[0074] The movable-side outer conductor 56 has an outer cylindrical base 57 and an outer elastic piece 58. In the present embodiment, the movable-side outer conductor 56 also has an outer opposite connecting portion 59.

[0075] The outer cylindrical base 57 is formed in a cylindrical shape that can house the movable-side insulator 50 on the inner side. A locking protrusion 57a can be provided protruding from the outer cylindrical base 57. The locking protrusion 57a partially protrudes from the inner circumferential portion of the outer cylindrical base 57. The locking protrusion 57a is formed in a shape in which the protruding dimension gradually decreases from one end toward the other end of the outer cylindrical base 57. In a state in which the movable-side insulator 50 is inserted into the outer cylindrical base 57, the locking protrusion 57a hooks the outer circumferential portion of the movable-side insulator 50, and the movable-side insulator 50 is held in a state in which it is prevented from coming off the outer cylindrical base 57.

[0076] The outer cylindrical base 57 can also have a positioning protrusion 57p (see FIG. 6) that partially protrudes inward in the circumferential direction. Figure 6 By the positioning protrusion 57p being fitted into a positioning recess formed in the outer circumference of the movable-side insulator 50, the rotation of the outer cylindrical base 57 relative to the movable-side insulator 50 can be stopped. By the positioning protrusion 57p being fitted into the positioning recess, the movement of the outer cylindrical base 57 relative to the movable-side insulator 50 toward the other end side can be restricted. By the outer cylindrical base 57 being fitted into the movable-side insulator 50, the outer cylindrical base 57 is disposed coaxially relative to the cylindrical base 43.

[0077] A plurality of outer side elastic pieces 58 extend from an end side opening edge of the outer side tubular base 57. The plurality of outer side elastic pieces 58 are arranged in a manner of surrounding the periphery of the one end portion of the movable side insulator 50.

[0078] More specifically, the outer side elastic piece 58 has an inclined portion 58a, a bulging portion 58b, and a tip end guide portion 58c. The inclined portion 58a, the bulging portion 58b, and the tip end guide portion 58c are connected in this order from the one end side opening of the outer side tubular base 57 toward the one side of the central axis X of the outer side tubular base 57.

[0079] The inclined portion 58a is inclined toward the outer peripheral side as it goes from the one end side opening of the outer side tubular base 57 toward the tip end of the outer side elastic piece 58. The inclined portion 58a is mainly elastically deformable in the inner-outer direction of the outer side tubular base 57 with the portion connected to the outer side tubular base 57 as a fulcrum.

[0080] The bulging portion 58b forms a curved surface that protrudes outward from the tip end of the inclined portion 58a and toward the one side of the central axis X. The portion that protrudes most outward in the bulging portion 58b is a portion that is directed outward in the radial direction of the outer side tubular base 57 and contacts the outer connection outer conductor 36.

[0081] The tip end guide portion 58c is inclined toward the inner peripheral side from the tip end of the bulging portion 58b toward the one side of the central axis X.

[0082] When the movable side outer conductor 56 is inserted into the outer connection outer conductor 36, the outer side elastic piece 58 is guided toward the inner peripheral side of the outer connection outer conductor 36 by the tip end guide portion 58c contacting the opening edge of the outer connection outer conductor 36. In the state where the movable side outer conductor 56 is inserted into the outer connection outer conductor 36, the inclined portion 58a is elastically deformed toward the inner peripheral side. The bulging portion 58b is elastically pressed to the inner peripheral surface of the outer connection outer conductor 36 by the elastic force of the inclined portion 58a that wants to return to the original shape. As a result, the plurality of outer side elastic pieces 58 contact the outer connection outer conductor 36 from the inner peripheral side, and the movable side outer conductor 56 and the outer connection outer conductor 36 are connected. The outer side opposite connection portion 59 is inserted and connected to the substrate side outer conductor 80.

[0083] <Position restricting structure of movable side inner conductor in movable side insulator> As described above, the movable side inner conductor 42 is formed with the slit 43g, and the movable side insulator 50 is formed with the rotation stop protrusion 53.

[0084] As described above, in the state where the tubular base 43 is inserted into the movable side insulator 50, the locking protrusion 43a is hooked to the inner peripheral portion of the movable side insulator 50, and the movable side inner conductor 42 is held in the movable side insulator 50 in a state where it is prevented from coming off. In this state, the rotation stop protrusion 53 is inserted into the slit 43g, and the rotation of the movable side inner conductor 42 is restricted.

[0085] The width of the pair of side surfaces 43gl of the slit 43g is set to be the same as or greater than the width of the rotation-stopping protrusion 53.

[0086] The width of the pair of side surfaces 43gl of the slit 43g is set to be the same as or greater than the width of the rotation-stopping protrusion 53. Even if the width of the pair of side surfaces 43gl of the slit 43g is greater than the width of the rotation-stopping protrusion 53, the movable-side inner conductor 42 can be rotationally stopped within a range where the rotation-stopping protrusion 53 is in contact with the pair of side surfaces 43gl.

[0087] Even if the width of the pair of side surfaces 43gl of the slit 43g is greater than the width of the rotation-stopping protrusion 53, it is preferable that the width is such that the inner peripheral portion of the movable-side outer conductor 56 and the elastic pieces 44 do not interfere with each other. For example, it is preferable that the pair of side surfaces 43gl are in contact with the rotation-stopping protrusion 53 within a range where any one of the plurality of elastic pieces 44 does not come into contact with the aforementioned portion 52p of the head portion 52, and the rotation of the movable-side inner conductor 42 can be restricted.

[0088] Further, it is preferable that the width Wa of the slit 43g is smaller than the width Wb of the gap between the elastic pieces 44 in a direction along the circumferential direction of the cylindrical base portion 43 (refer to FIG. 6). Figure 9 By making the width Wa of the slit 43g smaller than the width Wb of the gap between the elastic pieces 44, the strength of the cylindrical base portion 43 can be easily ensured. Further, the elastic pieces 44 can be easily stably elastically deformed at their base ends. Furthermore, the cylindrical base portion 43 can be made close to a uniform cylindrical shape, and thus the characteristic impedance required as a coaxial connector can be easily made good.

[0089] The end portion of the rotation-stopping protrusion 53 on the side opposite to the extending direction of the plurality of elastic pieces 44 can also be formed as a guide end portion 53g (refer to FIG. 6) whose width becomes smaller toward the tip end. Figure 4 Figure 8 When the rotation-stopping protrusion 53 is inserted into the slit 43g, the guide end portion 53g comes into contact with the opening of the slit 43g and guides toward the inside of the slit 43g. Thus, the rotation-stopping protrusion 53 is smoothly inserted into the slit 43g.

[0090] The opening portion of the slit 43g can also be formed so as to gradually expand toward the outside. The guide end portion 53g can be more easily formed by mold forming of resin than by press working of a metal plate.

[0091] ​Further, as described above, the movable-side inner conductor 42 is formed with a front stop face 43frs. The front stop face 43frs is located on the opposite side of the slit 43g around the center axis X. Further, the movable-side insulator 50 is formed with a front stop protrusion 54. The front stop protrusion 54 is located on the opposite side of the rotation stop protrusion 53 around the center axis X.

[0092] As described above, in a state where the cylindrical base 43 is inserted into the movable-side insulator 50, the engagement protrusion 43a is hooked to the inner peripheral portion of the movable-side insulator 50, and the movable-side inner conductor 42 is held in the movable-side insulator 50 in a state of being prevented from being removed. In this state, the front stop protrusion 54 is opposed to the front stop face 43frs. Preferably, the front stop protrusion 54 is in contact with the front stop face 43frs. By the front stop protrusion 54, the movable-side inner conductor 42 is restricted from moving to the side of the elastic pieces 44 relative to the movable-side insulator 50.

[0093] Preferably, in a direction along the circumferential direction of the cylindrical base 43, the width Wc of the front stop protrusion 54 is smaller than the width Wd of the gap between the elastic pieces 44. Thereby, when the elastic pieces 44 are elastically deformed in the inner-outer direction and in a state of having been elastically deformed, the elastic pieces 44 are less likely to interfere with the front stop protrusion 54. Therefore, when the outer-connection inner conductor 32 is inserted between the plurality of elastic pieces 44, the operation of the elastic pieces 44 is less likely to be hindered, and the insertion work can be easily performed. Further, even in the state of the insertion of the outer-connection inner conductor 32, the elastic pieces 44 are less likely to be hooked to the front stop protrusion 54, and can be securely in contact with the outer-connection inner conductor 32.

[0094] The relationship between the rotation stop protrusion 53 and the front stop protrusion 54 will be described.

[0095] Preferably, in a direction along the circumferential direction of the cylindrical base 43, the width Wc of the front stop protrusion 54 is larger than the width We of the rotation stop protrusion 53. Thereby, the strength of the front stop protrusion 54 that restricts the movable-side inner conductor 42 from moving to the tip end side can be increased. For example, in the assembly of the relay coaxial connector 40 and the plugging work of the connector and the like, it is possible that a rotational force and a force that moves the movable-side inner conductor 42 to the tip end side are applied to the movable-side inner conductor 42. In the process of fitting the movable-side inner conductor 42 into the movable-side insulator 50 and the process of pulling out the connector and the like, it is possible that a force that moves the movable-side inner conductor 42 to the tip end side is applied to the movable-side inner conductor 42. By increasing the width Wc of the front stop protrusion 54, the movable-side inner conductor 42 can be securely restricted from moving to the tip end side.

[0096] Further, since the gap is originally formed between the plurality of elastic pieces 44, even if the width of the rotation stop protrusion 53 disposed in the gap is increased within a range that does not interfere with the elastic pieces 44, the strength of the movable-side inner conductor 42 is less likely to be affected. Further, the characteristic impedance of the coaxial connector is less likely to be affected.

[0097] In the state where the front stop protrusion 54 is in contact with the front stop face 43frs, the rotation stop protrusion 53 can or can not be in contact with the inner side face 43g2 of the slit 43g. Figure 5 In the example shown, in the state where the front stop protrusion 54 is in contact with the front stop face 43frs, the rotation stop protrusion 53 is in contact with the inner side face 43g2 of the slit 43g.

[0098] As in the modification example shown, in the state where the front stop protrusion 54 is in contact with the front stop face 43frs, the rotation stop protrusion 153 corresponding to the rotation stop protrusion 53 can also be opposed to the inner side face 43g2 of the slit 43g with the gap Ga therebetween. Figure 11

[0099] In this case, when the movable-side inner conductor 42 is pressed toward the movable-side insulator 50, if the front stop protrusion 54 comes into contact with the front stop face 43frs, the pressing force does not easily act on the rotation stop protrusion 53. In the case where the rotation stop protrusion 53 is thinner than the front stop protrusion 54, the pressing force can be borne by the comparatively thick front stop protrusion 54, and the force applied to the thin rotation stop protrusion 53 can be reduced.

[0100] <Effects, etc.> According to the relay coaxial connector 40 thus configured, in the state where at least a part of the movable-side inner conductor 42 is housed in the housing space S of the movable-side insulator 50, the rotation stop protrusion 53 is inserted into the slit 43g of the cylindrical base 43. By the rotation stop protrusion 53 being positioned between the pair of side faces 43g1 of the slit 43g, the movable-side inner conductor 42 is restricted from rotating. By the movable-side inner conductor 42 being restricted from rotating, the position of the elastic piece 44 in the movable-side insulator 50 is stabilized, and the interference of the elastic piece 44 with the rotation stop protrusion and the deformation of the elastic piece 44 and the like that are not intended can be suppressed.

[0101] Further, since the width Wa of the slit 43g is smaller than the width Wb of the gap between the elastic pieces 44, the slit 43g and the rotation stop protrusion 53 inserted into the slit do not easily affect the elastic deformation of the plurality of elastic pieces 44. Further, in the relay coaxial connector 40, the portion without electrical conductivity can be reduced and the coaxial shape portion can be increased, and the characteristic impedance is not easily affected.

[0102] Further, the front stop protrusion 54, which is distinct from the rotation stop protrusion 53 described above, is opposed to the front stop face 43frs. By the front stop protrusion 54 coming into contact with the front stop face 43frs, the movable-side inner conductor 42 is restricted from moving toward the tip end side.

[0103] In particular, by making the width Wc of the front stop protrusion 54 larger than the width We of the rotation stop protrusion 53, the movable-side inner conductor 42 can be more reliably restricted from moving toward the tip end side by the front stop protrusion 54, which is thick in width. ​

[0104] For example, as in the modification of the stopper protrusion 153, the stopper protrusion 153 can be opposed to the inner side surface 43g2 of the slit 43g with a space therebetween. In this case, the force with which the movable side inner conductor 42 attempts to move toward the tip end side is received by the front stopper protrusion 54. Therefore, the force applied to the stopper protrusion 53 can be reduced, and the stopper protrusion 53 can be reduced in size. Since the width of the slit 43g can be made narrow, the characteristic impedance performance is less likely to be affected.

[0105] Further, by making the width of the front stopper protrusion 54 smaller than the width of the elastic piece 44, the elastic piece 44 that is elastically deformed is less likely to interfere with the front stopper protrusion 54. Thus, the deformation of the elastic piece 44 other than the intended deformation of the elastic piece 44 can be suppressed.

[0106] Further, the movable side insulator 50 includes a head portion 52 that covers the tip end portions of the plurality of elastic pieces 44, and the head portion 52 includes a portion 52p that enters between the plurality of elastic pieces 44. In this case, the head portion 52 can be made to approach the elastic pieces 44 as much as possible, and the elastic pieces 44 can be easily protected. Further, the disposition site of the dielectric body can be increased around the elastic pieces 44, and the characteristic impedance can be easily made good.

[0107] Further, the pair of side surfaces 43gl contacts the stopper protrusion 53 in a range in which the elastic piece 44 and the above-mentioned portion 52p of the head portion 52 are prevented from contacting each other, and the rotation of the movable side inner conductor 42 is restricted. Thus, the deformation of the elastic piece 44 caused by the contact between the elastic piece 44 and the head portion 52 can be suppressed.

[0108] Further, since the stopper protrusion 53 has the guide end portion 53g, the stopper protrusion 53 can be easily fitted into the slit 43g.

[0109] The above-mentioned structures are incorporated into the relay coaxial connector 40 as the coaxial connector, and thus the movable side insulator 50 as the terminal housing member is used as the dielectric body. In order to increase the disposition site of the dielectric body, even in the case where the distance between the movable side insulator 50 and the movable side inner conductor 42 is reduced, the rotation of the movable side inner conductor 42 can be restricted, and thus the elastic piece 44 and the movable side insulator 50 are less likely to contact each other, and the deformation of the elastic piece 44 can be suppressed.

[0110] Further, the structures described in the above-mentioned embodiments and modifications can be appropriately combined as long as they do not contradict each other. Explanation of Reference Numerals
