Summary of the Invention

Problems to be Solved by the Invention

[0005] In the floating connector as described above, since a space for the intermediate elastic portion of the signal terminal to deform is required, the intermediate elastic portion is exposed in the air. Therefore, the impedance of the signal terminal is likely to increase in the intermediate elastic portion. If the impedance is likely to increase in a part of the signal terminal, there is a problem that it becomes difficult to match the impedance of the signal terminal.

[0006] The first object of this disclosure is to suppress the increase in impedance of an intermediate elastic portion when a signal terminal has an intermediate elastic portion. [Means for solving the problem]

[0007] In this disclosure, when describing the structure and shape of an object (connector, its components, etc.), the X, Y, and Z directions are used as directional concepts relative to the object, and are mutually perpendicular to each other.

[0008] <First aspect> A floating connector according to the first embodiment comprises a fixed housing fixed to an object to be attached, a movable housing movable relative to the fixed housing, a signal terminal having a fixed-side retained portion held by the fixed housing, a movable-side retained portion held by the movable housing, and an elastically deformable intermediate elastic portion located between the fixed-side retained portion and the movable-side retained portion, and a shield terminal having an intermediate shield portion that shields the intermediate elastic portion.

[0009] In the above embodiment, the floating connector comprises a fixed housing fixed to an object to be attached, a movable housing movable relative to the fixed housing, and a signal terminal. The signal terminal has a fixed-side retained portion held by the fixed housing, a movable-side retained portion held by the movable housing, and an elastically deformable intermediate elastic portion located between the fixed-side retained portion and the movable-side retained portion.

[0010] Here, the floating connector is equipped with a shielded terminal having an intermediate shield. The intermediate shield shields the intermediate elastic part. Therefore, the increase in impedance of the intermediate elastic part is suppressed.

[0011] A floating connector according to the first-second embodiment, in the first-first embodiment, has a shield terminal comprising a shield fixed-side retained portion held by the fixed housing, a shield movable-side retained portion held by the movable housing, and an intermediate shield portion located between the shield fixed-side retained portion and the shield movable-side retained portion, wherein the shield terminal has an elastically deformable fixed-side connecting portion connecting the intermediate shield portion and the shield fixed-side retained portion, or an elastically deformable movable-side connecting portion connecting the intermediate shield portion and the shield movable-side retained portion.

[0012] In the above embodiment, the shield terminal has a shield fixed-side retaining portion held by a fixed housing, a shield movable-side retaining portion held by a movable housing, and an intermediate shield portion located between the shield fixed-side retaining portion and the shield movable-side retaining portion.

[0013] Here, the shield terminal has an elastically deformable fixed-side connecting portion that connects the intermediate shield portion and the shield fixed-side holding portion, or an elastically deformable movable-side connecting portion that connects the intermediate shield portion and the shield movable-side holding portion. Therefore, the movement of the movable housing relative to the fixed housing is permitted by the deformation of the fixed-side connecting portion or the movable-side connecting portion.

[0014] In the floating connector according to the first to third embodiments, the fixed-side connecting portion or the movable-side connecting portion is narrower than the intermediate shield portion, as in the first to second embodiments.

[0015] In the above embodiment, the fixed-side connecting portion or the movable-side connecting portion is narrower than the intermediate shield portion. Therefore, the relatively narrow fixed-side connecting portion or movable-side connecting portion allows the movable housing to move relative to the fixed housing, while the relatively wide intermediate shield portion shields the intermediate elastic portion over a wide area.

[0016] A floating connector according to the first to fourth embodiments, in the first to fourth embodiment, the shield terminal has a shield fixed-side retained portion held by the fixed housing, a shield movable-side retained portion held by the movable housing, and an intermediate shield portion located between the shield fixed-side retained portion and the shield movable-side retained portion, and the shield terminal has an elastically deformable fixed-side connecting portion connecting the intermediate shield portion and the shield fixed-side retained portion, and an elastically deformable movable-side connecting portion connecting the intermediate shield portion and the shield movable-side retained portion.

[0017] In the above embodiment, the shield terminal has an elastically deformable fixed-side connecting portion that connects the intermediate shield portion and the shield fixed-side holding portion, and an elastically deformable movable-side connecting portion that connects the intermediate shield portion and the shield movable-side holding portion. Therefore, not only is the movement of the movable housing relative to the fixed housing permitted, but the movement of the intermediate shield portion relative to both the fixed housing and the movable housing is also permitted.

[0018] In the floating connector according to the first to fifth embodiments, the fixed-side connecting portion and the movable-side connecting portion are narrower than the intermediate shield portion, as in the first to fourth embodiments.

[0019] In the above embodiment, the fixed-side connecting portion and the movable-side connecting portion are narrower than the intermediate shield portion. As a result, the relatively narrow fixed-side and movable-side connecting parts allow the movable housing to move relative to the fixed housing, as well as the intermediate shielding part to move relative to both the fixed and movable housings, while the relatively wide intermediate shielding part shields the intermediate elastic part of the signal terminal over a wide area.

[0020] In the floating connector according to the 1st to 6th embodiments, in any of the 1st to 1st to 5th embodiments, the intermediate shield portion shields the intermediate elastic portion from two or more directions.

[0021] In the above aspect, the intermediate shielding portion shields the intermediate elastic portion from two or more directions. Therefore, the impedance of the intermediate elastic portion can be significantly reduced as compared with an aspect in which the intermediate shielding portion shields the intermediate elastic portion from only one direction.

[0022] In the floating connector according to the 1st to 7th aspects, in any of the 1st-1 to 1st-6 aspects, the intermediate shielding portion has one intermediate side portion and the other intermediate side portion that shield the intermediate elastic portion from the +Y direction and the -Y direction.

Therefore, the intermediate elastic portion is shielded from the direction that surrounds its signal path. The term "cylindrical section surrounding the signal path" as used here includes not only perfectly cylindrical sections with no gaps in the circumferential direction, but also sections with slight gaps in the circumferential direction.

[0034] In the floating connector according to the 1-13 embodiment, in any of the 1-1 to 1-12 embodiments, the intermediate elastic portion extends along a plane perpendicular to the Y direction, and the thickness direction of the intermediate elastic portion is oriented perpendicular to the Y direction.

[0035] In the above embodiment, the intermediate elastic portion extends along a plane perpendicular to the Y direction, and the thickness direction of the intermediate elastic portion is perpendicular to the Y direction.

[0092] A floating connector according to the 1st to 42nd embodiment, in the 1st to 41st embodiment, the intermediate shield portion is located between the fixed side shield portion and the movable side shield portion, the shield terminal has an elastically deformable fixed side connecting portion that connects the intermediate shield portion and the fixed side shield portion, and an elastically deformable movable side connecting portion that connects the intermediate shield portion and the movable side shield portion, the fixed side connecting portion has one fixed side connecting portion and the other fixed side connecting portion that shields the intermediate elastic portion from the +Y direction and the -Y direction, and the movable side connecting portion has one movable side connecting portion and the other movable side connecting portion that shields the intermediate elastic portion from the +Y direction and the -Y direction.

[0093] In the above embodiment, the fixed-side connecting portion has one fixed-side connecting portion and the other fixed-side connecting portion that shields the intermediate elastic portion from the +Y direction and the -Y direction, and the movable-side connecting portion has one movable-side connecting portion and the other movable-side connecting portion that shields the intermediate elastic portion from the +Y direction and the -Y direction. Therefore, the intermediate elastic portion of the signal terminal is shielded by both the fixed and movable connecting parts, resulting in a more appropriate impedance match for the signal terminal.

[0094] In the floating connector according to the 1st to 43rd embodiment, in the 1st to 41st or 1st to 42nd embodiment, the intermediate shield portion has an intermediate vertical portion that shields the intermediate elastic portion from a direction perpendicular to the Y direction, the fixed-side shield portion has a fixed-side vertical portion that shields the fixed-side retained portion from a direction perpendicular to the Y direction, and the movable-side shield portion has a movable-side vertical portion that shields the movable-side retained portion from a direction perpendicular to the Y direction.

[0095] In the above embodiment, the intermediate elastic portion, the fixed-side retained portion, and the movable-side retained portion are each shielded from a direction perpendicular to the Y direction, so that the impedance of the signal terminals is matched more appropriately.

[0096] In the floating connector according to the 1st to 44th embodiment, the intermediate shield portion has an intermediate vertical portion that shields the intermediate elastic portion from a direction perpendicular to the Y direction, the shield terminal is press-fitted into the movable housing from the -Z direction side, and the intermediate vertical portion is positioned on the -Z direction side of the intermediate elastic portion.

[0097] In the above embodiment, the intermediate vertical portion is positioned on the -Z direction side of the intermediate elastic portion. Therefore, when the shield terminal is press-fitted into the movable housing from the -Z direction, the shield terminal can be press-fitted into the movable housing that is already holding the signal terminal. In the embodiments described later, the movable housing is held to the signal terminals by press-fitting. However, this embodiment is not limited to this, and the movable housing may be held to the signal terminals by insert molding.

[0098] In the first embodiment of the 1-45, the floating connector comprises an additional shielding member, the additional shielding member having a fixed-side vertical portion that shields the fixed-side retained portion from a direction perpendicular to the Y direction.

[0099] In the above embodiment, the floating connector includes an additional shielding member. The additional shielding member has a fixed-side vertical portion that shields the fixed-side retained portion from a direction perpendicular to the Y direction. Therefore, even when the shield terminal does not have a fixed-side vertical portion or when the shielding effect of the fixed-side vertical portion of the shield terminal is insufficient, the fixed-side held portion can be shielded from a direction perpendicular to the Y direction. Furthermore, the absence of a fixed vertical portion in the shield terminal offers advantages such as facilitating the formation of the shield terminal and improving workability in the process of holding the signal terminal and shield terminal in the movable housing.

[0100] In the first embodiment of the 1-46, the floating connector comprises an additional shielding member, the additional shielding member having a portion that shields the intermediate elastic portion from the -X direction side.

[0101] In the above embodiment, the floating connector includes an additional shielding member. The additional shielding member has a portion that shields the intermediate elastic portion from the -X direction side. Therefore, even if the shielding of the intermediate elastic section is insufficient with only the shield terminal, the shielding effect on the intermediate elastic section can be enhanced. Furthermore, due to manufacturing and other reasons related to the shield terminals, it may not always be easy to adequately shield the intermediate elastic section using only the shield terminals.

[0102] In the first embodiment of the 1-47, the floating connector has, in the first embodiment, an intermediate shield portion having one intermediate lateral portion and the other intermediate lateral portion that shield the intermediate elastic portion from the +Y direction and the -Y direction, and an intermediate vertical portion that shields the intermediate elastic portion from a direction perpendicular to the Y direction, the intermediate vertical portion having one intermediate vertical portion connected to the one intermediate lateral portion via a curved portion, the other intermediate vertical portion connected to the other intermediate lateral portion via a curved portion, the end of the one intermediate vertical portion and the end of the other intermediate vertical portion facing each other in the Y direction, and the end of the one intermediate vertical portion and the end of the other intermediate vertical portion having a shape that allows for a partial overlap in the manufacturing process of the shield terminal when viewed from the thickness direction of their plates.

[0103] In the above embodiment, the end of one intermediate vertical section and the end of the other intermediate vertical section face each other in the Y direction. In this case, a smaller gap between the two is preferable from the standpoint of shielding effectiveness. Therefore, in the above embodiment, the end of one intermediate vertical section and the end of the other intermediate vertical section are shaped such that, when viewed from the thickness direction of the plates, a portion of them overlap during the manufacturing process of the shield terminal. Therefore, the gap can be reduced by having the ends of one intermediate vertical section and the other intermediate vertical section overlap in part when viewed from the thickness direction of the shield terminal during the manufacturing process.

[0104] <Second aspect> The connector relating to the aspect of 2-1 is A connector comprising a base having an inner conductor portion, an outer conductor portion surrounding the inner conductor portion, and a dielectric portion disposed between the inner conductor portion and the outer conductor portion, and a tip portion insertable in the -Z direction into a mating hole of a mating connector, wherein the tip portion has a signal contact portion connected to the inner conductor portion and in contact with the mating signal terminal of the mating connector, and a shield contact portion connected to the outer conductor portion and in contact with the mating shield terminal of the mating connector, and the tip portion is smaller than the base portion with respect to the cross-sectional area perpendicular to the -Z direction.

[0105] In the above embodiment, the connector comprises a base portion and a tip portion that can be inserted in the -Z direction into the mating hole of the mating connector. The base portion has an inner conductor portion, an outer conductor portion surrounding the inner conductor portion, and a dielectric portion disposed between the inner conductor portion and the outer conductor portion. Therefore, the impedance of the inner conductor is matched.

[0106] The tip has a signal contact portion that contacts the mating signal terminal of the mating connector, and a shield contact portion that contacts the mating shield terminal of the mating connector. The signal contact portion is connected to the inner conductor portion, and the shield contact portion is connected to the outer conductor portion. Therefore, when the tip is inserted into the mating hole of the mating connector, the outer conductor portion of the base is connected to the mating shield terminal of the mating connector, and the inner conductor portion of the base is connected to the mating signal terminal of the mating connector.

[0107] Here, with respect to the cross-sectional area perpendicular to the -Z direction (the direction in which the tip is inserted into the fitting hole, hereafter sometimes referred to as the insertion direction), the cross-sectional area of ​​the tip is smaller than that of the base. In other words, the cross-sectional area of ​​the tip (the cross-sectional area perpendicular to the insertion direction) is smaller than the cross-sectional area of ​​the base (the cross-sectional area perpendicular to the insertion direction). Therefore, compared to a configuration where the cross-sectional area of ​​the tip is the same as the cross-sectional area of ​​the base, the cross-sectional area of ​​the mating hole in the mating connector (the cross-sectional area perpendicular to the insertion direction) can be smaller. As a result, the portion of the mating connector in which the mating hole is formed (the mating portion) can be miniaturized in the direction perpendicular to the insertion direction without reducing the cross-sectional area of ​​the base.

[0108] In the second embodiment of the connector, the tip portion is shaped to be hidden by the base portion when viewed in the Z direction, as in the second embodiment of the connector.

[0109] In the above embodiment, the tip is shaped to be hidden by the base when viewed in the Z direction. Therefore, the connector can be miniaturized in the direction perpendicular to the insertion direction.

[0110] In the connector according to the second-third embodiment, the tip portion and the base portion are adjacent in the Z direction, as in the second-first or second-second embodiment.

[0111] In the above embodiment, the tip and base are adjacent in the Z direction. Therefore, the connector can be made smaller compared to an embodiment in which another structure exists between the tip and base.

[0112] In the second-to-fourth embodiment, the dielectric portion of the base has an exposed surface that is exposed so as to be able to face the mating connector.

[0113] In the above embodiment, the dielectric portion of the base has an exposed surface that is exposed so as to be able to face the mating connector. Therefore, the connector can be made smaller compared to an embodiment in which another structure is interposed between the dielectric portion of the base and the mating connector.

[0114] In the connector according to embodiment 2-5, in any embodiment 2-1 to 2-4, the signal contact portion and the shield contact portion are formed on the -X direction side of the tip portion, and the shield contact portion has one shield contact portion and the other shield contact portion located on the +Y direction side and the -Y direction side of the signal contact portion.

[0115] In the above embodiment, the signal contact portion and the shield contact portion are formed on the -X direction side of the tip portion. The shield contact portion has one shield contact portion and the other shield contact portion located on the +Y direction side and the -Y direction side of the signal contact portion. Therefore, the signal contact area is shielded from both sides in the Y direction.

[0116] The connector according to the second-sixth embodiment, in the second-fifth embodiment, has a tip portion comprising a tip portion-side dielectric portion and a tip portion-side outer conductor portion covering the outer surface of the tip portion-side dielectric portion, the tip portion-side outer conductor portion comprising one and the other X-direction side portions covering the tip portion-side dielectric portion from the +X and -X directions, and one and the other Y-direction side portions covering the tip portion-side dielectric portion from the +Y and -Y directions, the one shield contact portion and the other shield contact portion being formed on the other X-direction side portion.

[0117] In the above embodiment, the tip portion has a tip-side dielectric portion and a tip-side outer conductor portion that covers the outer surface of the tip-side dielectric portion. The tip-side outer conductor portion has one and the other X-direction side portions that cover the tip-side dielectric portion from the +X and -X directions, and one and the other Y-direction side portions that cover the tip-side dielectric portion from the +Y and -Y directions. The one shield contact portion and the other shield contact portion are formed on the other X-direction side portion. As a result, the outer conductor portion at the tip is positioned to roughly surround the dielectric portion at the tip, which further reduces the impedance.

[0118] The connector according to the second-seventh embodiment, in the second-first embodiment, comprises a signal terminal on which the inner conductor portion and the signal contact portion of the base are formed, a shield terminal on which the outer conductor portion and the shield contact portion of the base are formed, and a housing on which the base-side dielectric portion, which is the dielectric portion of the base, is formed, wherein the housing has a tip-side dielectric portion that constitutes a part of the tip portion, and the shield terminal has one and the other base-side X-direction portions that cover the base-side dielectric portion from the +X direction and the -X direction, and one and the other tip-side dielectric portion that cover the tip-side dielectric portion from the +X direction and the -X direction. Tip side X direction part The shield terminal is formed by bending a plate material, and a carrier cutting portion is formed at the +Z direction end of the X-direction portion of one base side, or at the +Z direction end of the X-direction portion of the other base side, where the connection portion with the carrier in the manufacturing process of the shield terminal is cut off. When the bent portion of the shield terminal is unfolded with reference to the X-direction portion of one base side, the X-direction portion of one base side, the X-direction portion of the other tip side, and the X-direction portion of the other base side are arranged in this order along the Z direction.

[0119] In the above embodiment, the connector comprises a signal terminal, a shield terminal, and a housing. The signal terminal has an inner conductor portion and a signal contact portion formed at the base. The shield terminal has an outer conductor portion and a shield contact portion formed at the base. The housing has a base-side dielectric portion which is the dielectric portion of the base, and a tip-side dielectric portion which constitutes a part of the tip. The shield terminal has one and the other base-side X-direction portions, and one and the other Tip side X direction part It has the following features. The shield terminal is formed by bending a plate material.

[0120] Here, a carrier cutting portion is formed at the +Z direction end of one base-side X-direction portion, or at the +Z direction end of the other base-side X-direction portion, where the connection portion with the carrier during the manufacturing process of the shield terminal is cut off. When the bent portion of the shield terminal is unfolded with reference to one base-side X-direction portion, the one base-side X-direction portion, the one tip-side X-direction portion, the other tip-side X-direction portion, and the other base-side X-direction portion are aligned in this order along the Z direction. Therefore, in the state before bending during the manufacturing process of the shield terminal, one base-side X-direction portion, one tip-side X-direction portion, the other tip-side X-direction portion, and the other base-side X-direction portion are arranged in a direction perpendicular to the carrier feed direction. Consequently, shield terminals can be formed from materials with small dimensions in the carrier feed direction. Thus, shield terminals can be manufactured efficiently with respect to the dimensions of the material in the carrier feed direction.

[0121] The connector according to the second-eighth embodiment, in the second-first embodiment, comprises a signal terminal on which the inner conductor portion and the signal contact portion of the base are formed, a shield terminal on which the outer conductor portion and the shield contact portion of the base are formed, and a housing on which the base-side dielectric portion, which is the dielectric portion of the base, is formed, wherein the housing has a tip-side dielectric portion that constitutes a part of the tip portion, and the shield terminal covers the tip-side dielectric portion from the +X direction and the -X direction, one and the other Tip side X direction part And the aforementioned one Tip side X direction part The end on the -Z direction side and the other side Tip side X direction part It has a tip-side connecting portion that connects to the end on the -Z direction side, and the shield contact portion is the other Tip side X direction part The tip-side connecting portion is formed in such a way that it is curved, with the -Z direction being convex when viewed from the Y direction.

[0122] In the above embodiment, the shield terminal is one Tip side X direction part The end on the -Z direction side and the other Tip side X direction part It has a tip-side connecting portion that connects to the end on the -Z direction side. The tip-side connecting portion is bent into a curved shape that is convex in the -Z direction when viewed from the Y direction. Therefore, when connecting a connector to a mating connector, even if the mating shield terminal of the mating connector comes into contact with the tip-side connecting portion, the other connector where the shield contact portion is formed... Tip side X direction part It allows for smooth guidance of the other shield terminal.

[0123] The connector according to the second-nine embodiment, in the second-first embodiment, comprises a signal terminal on which the inner conductor portion and the signal contact portion of the base are formed, a shield terminal on which the outer conductor portion and the shield contact portion of the base are formed, and a housing on which the base-side dielectric portion, which is the dielectric portion of the base, is formed, wherein the housing has a tip-side dielectric portion that constitutes a part of the tip portion, and the shield terminal has a other base-side X-direction portion that covers the base-side dielectric portion from the -X direction side, and a other portion that covers the tip-side dielectric portion from the -X direction side Tip side X direction part and the other base side X direction portion and the other Tip side X direction part It has an intermediate connecting part that connects the other and the base side X direction part and the other Tip side X direction part These are located at different positions in the X direction, and the shield contact portion is the other Tip side X direction part The intermediate connecting portion is formed such that the end of the X-direction portion on the base side of the other part is on the -Z-direction side, and the other part Tip side X direction part Connect it to the end on the +Z direction side.

[0124] In the above embodiment, the intermediate connecting portion is the -Z direction end of the X direction portion on the other base side and the other Tip side X direction part Connect it to the end on the +Z direction side. Therefore, the other base side X direction part and the other Tip side X direction part These are connected by a short route. Therefore, the current path formed by the shield terminal is easily shortened.

[0125] <Third aspect> The connector according to the third-first embodiment is a connector comprising a tip portion that mates with a mating connector and a base portion connected to the tip portion, wherein the base portion has a base-side inner conductor portion, a cylindrical base-side outer conductor portion surrounding the base-side inner conductor portion, and a base-side dielectric portion disposed between the base-side outer conductor portion and the base-side inner conductor portion, and the tip portion has a signal contact portion connected to the base-side inner conductor portion and a tip-side dielectric portion on which the signal contact portion is disposed, wherein the signal contact portion is configured to contact the signal terminal of the mating connector on one side and to contact the tip-side dielectric portion on the other side.

[0126] In the above embodiment, the connector comprises a tip portion that mates with a mating connector and a base portion that connects to the tip portion. The base portion has a base-side inner conductor portion, a cylindrical base-side outer conductor portion that surrounds the base-side inner conductor portion, and a base-side dielectric portion disposed between the base-side outer conductor portion and the base-side inner conductor portion. Therefore, the impedance of the inner conductor portion on the base side is matched.

[0127] Here, the tip portion has a signal contact portion connected to the inner conductor portion on the base side, and a dielectric portion on the tip side on which the signal contact portion is located on the surface. The signal contact portion is configured to contact the signal terminal of the mating connector on one side, and to contact the dielectric portion on the tip side on the other side. Therefore, even if the signal contact portion comes into contact with and is pressed against the signal terminal of the mating connector, the dielectric portion on the tip side located behind it suppresses deformation of the signal contact portion. In addition, since it is not necessary to clamp the signal contact portion to the signal terminal of the mating connector, it is easier to design the signal terminal of the mating connector to be suitable for high-speed transmission.

[0128] In the floating connector according to the third-second embodiment, the tip portion has a shield contact portion connected to the base-side outer conductor portion, and the shield contact portion is configured to contact the shield terminal of the mating connector on one side and to contact the tip-side dielectric portion on the other side.

[0129] In the above embodiment, the tip portion has a shield contact portion connected to the outer conductor portion on the base side. The shield contact portion is configured to contact the shield terminal of the mating connector on one side and to contact the dielectric portion on the tip side on the other side. Therefore, even if the shield contact portion comes into contact with and is pressed against the shield terminal of the mating connector, the dielectric portion on the tip side located behind it suppresses deformation of the shield contact portion.

[0130] <Fourth aspect> A floating connector according to the 4-1 embodiment is a floating connector connectable to a mating connector having an inner conductor portion, a cylindrical outer conductor portion surrounding the inner conductor portion, and a dielectric portion disposed between the inner conductor portion and the outer conductor portion, comprising a fixed housing fixed to an object to be attached, a movable housing movable relative to the fixed housing, a signal terminal connected to the inner conductor portion, and a shield terminal connected to the outer conductor portion, wherein the shield terminal has a shield movable side holding portion held by the movable housing, and an elastic support portion extending from the shield movable side holding portion and elastically supporting a shield contact portion that contacts the outer conductor portion.

[0131] Incidentally, a floating connector, such as the one described in Patent Document 2, is known. This floating connector connects to a mating connector that comprises an inner conductor portion, a cylindrical outer conductor portion surrounding the inner conductor portion, and a dielectric portion disposed between the inner and outer conductor portions. Specifically, a floating spring with contacts is connected to the inner conductor portion, and a pair of elastic contact pieces are connected to the outer conductor portion. However, in such floating connectors, a pair of highly flexible elastic contact pieces serve two functions: to accommodate misalignment and to make contact with the outer conductor. Therefore, as shown in Figure 12(b) of Patent Document 2, when the movable housing moves significantly, one of the elastic contact pieces separates from the outer conductor. As a result, the separated elastic contact piece may act like an antenna and become a source of noise.

[0132] In contrast, in the above embodiment, the shield terminal has a shield movable side holding portion held by a movable housing, and an elastic support portion extending from the shield movable side holding portion and elastically supporting the shield contact portion that contacts the outer conductor portion. Therefore, since a portion of the shield terminal (the part of the shield that is held on the movable side) moves together with the movable housing, even if the movable housing moves significantly, the part of the shield that is held on the movable side, located on the base end side of the elastic support, moves together with the movable housing, thus preventing the shield contact from separating from the outer conductor.

[0133] The bent product according to the fifth embodiment is formed by bending a sheet material and has a pair of ends that face each other in a predetermined opposing direction, and the pair of ends are shaped in such a way that a portion of them overlap when viewed from the thickness direction of the sheet material during the manufacturing process of the bent product.

[0134] The bent product according to the above embodiment is formed by bending a sheet material. The bent product has a pair of ends that face each other in a predetermined opposing direction. Here, the pair of ends have a shape that allows for a partial overlap when viewed from the thickness direction of the end during the manufacturing process of the bent product. Therefore, by having a pair of ends overlap in part when viewed from the thickness direction of the end during the manufacturing process of the bent product, the gap between the pair of ends can be reduced. In the embodiments described later, an example is given where the bent product is a shield terminal, but this embodiment is not limited to this. The bent product may be a signal terminal, another connector component, or not a connector component at all. [Brief explanation of the drawing]

[0136] For the sake of explanation, the ±X direction may be described as the front-to-back direction, the ±Y direction as the width direction, and the ±Z direction as the up-and-down direction.

[0137] [First Embodiment] The first connector 100 and the second connector 200 according to the first embodiment of this disclosure will be described with reference to Figures 1 to 16.

[0138] The first connector 100 is mounted on the first circuit board 91 (see Figure 5), and the second connector 200 is mounted on the second circuit board 92. The first connector 100 and the second connector 200 are configured to be connectable to each other. By connecting the first connector 100 mounted on the first circuit board 91 and the second connector 200 mounted on the second circuit board 92, the first circuit board 91 and the second circuit board 92 are electrically connected (see Figures 6 and 8).

[0139] <First connector 100> The first connector 100 is a floating connector. The first connector 100 comprises a fixed housing 10, a movable housing 50, a signal terminal 30, a shield terminal 40, and fixing members 20, 20.

[0140] (Fixed housing 10) The fixed housing 10 is a housing that is fixed to the first substrate 91. The fixed housing 10 is made of an insulator such as synthetic resin.

[0141] As shown in Figure 1, the fixed housing 10 has a peripheral wall portion 11 and a bottom wall portion 12. The peripheral wall portion 11 has a front wall portion 11a, a rear wall portion 11b, and a pair of width wall portions 11c.

[0142] The fixed housing 10 holds the fixed-side retained portion 32 of the signal terminal 30. Specifically, the front wall portion 11a of the fixed housing 10 holds the fixed-side retained portion 32 of the signal terminal 30. The fixed-side retained portion 32 is held at the center of the width direction of the front wall portion 11a. Specifically, a groove is formed in the center of the width direction of the front wall portion 11a for press-fitting the fixed-side retained portion 32. The fixed-side retained portion 32 of the signal terminal 30 is press-fitted into this groove from the +Z direction side.

[0143] The fixed housing 10 holds the shield-fixing side retained portion 42 of the shield terminal 40. Specifically, the front wall portion 11a of the fixed housing 10 holds the shield fixing side retained portion 42 of the shield terminal 40. The shield fixing side retained portion 42 is held at the center in the width direction of the front wall portion 11a.

[0144] The fixed housing 10 holds the fixing members 20, 20. Specifically, press-fit grooves into which the press-fit portion 23 of the fixing member 20 is press-fitted are formed at positions corresponding to the four corners of the fixing housing 10. The fixing members 20, 20 are press-fitted into the fixing housing 10 from the outside in the width direction.

[0145] In the widthwise central portion of the front wall portion 11a, the upper surface is formed lower than that of the widthwise outer portion of the front wall portion 11a. The upper surfaces of the rear wall portion 11b and the pair of widthwise wall portions 11c are at the same height as the upper surface of the widthwise outer portion of the front wall portion 11a. The fixed-side retaining portion 32 of the signal terminal 30 and the shield fixed-side retaining portion 42 of the shield terminal 40 are held in the widthwise central portion of the front wall portion 11a (the portion with a lower upper surface).

[0146] (Fixing member 20) The fixing members 20, 20 are members for fixing the fixing housing 10 to the substrate 91, and are made of metal, for example.

[0147] As shown in Figure 2, the fixing members 20, 20 consist of a right-side member 20 and a left-side member 20. The right-side member 20 and the left-side member 20 have similar structures. Hereafter, unless otherwise specified, the right-side member 20 and the left-side member 20 will be referred to as the fixing member 20.

[0148] The fixing member 20 has a pair of tail portions 21, a pair of vertical portions 22, a pair of press-fit portions 23, and an upper limiting portion 24. The pair of tail portions 21 are fixed to the first substrate 91 by soldering or the like. The pair of vertical portions 22 extend upward from the pair of tail portions 21. The pair of press-fit portions 23 are each formed to protrude in the Y direction from the pair of vertical portions 22. The pair of press-fit portions 23 are press-fitted into the fixing housing 10. The upper limiting portion 24 connects the upper ends of the pair of vertical portions 22.

[0149] The fixing member 20 is manufactured by punching and bending a plate material. The fixing member 20 is oriented perpendicular to the Y direction in the plate thickness direction.

[0150] The fixed housing 10 and the fixing members 20, 20 constitute the fixed side members 10, 20.

[0151] (Movable housing 50) The movable housing 50 is a housing that can move relative to the fixed housing 10. The movable housing 50 is made of an insulator such as synthetic resin.

[0152] The movable housing 50 has a fitting portion 51 and an engaging portion 52.

[0153] A mating hole 51a is formed in the mating portion 51 into which the tip portion 202 of the second connector 200 is inserted. The mating hole 51a is configured to receive the tip portion 202 of the second connector 200 inserted from the +Z direction side. The mating hole 51a has a rectangular cross-sectional shape with the width direction as the longitudinal direction.

[0154] A recess 51b is formed on the front surface of the mating portion 51, which is recessed in the rearward direction and extends in the vertical direction. As a result, the front wall of the mating portion 51 has a thinner wall thickness in a part of the width direction, allowing the board connection portion 31 of the signal terminal 30 and the board connection portion 41 of the shield terminal 40 to be seen in the Z direction.

[0155] On the inner surface of the fitting hole 51a, on the rear side, there is an arrangement groove 51c where the tip sides 35 and 36 of the signal terminal 30 are positioned, and an arrangement groove 51d where the tip side 47a of the shield terminal 40 is positioned.

[0156] The engaging portion 52 is formed on the lower side of the fitting portion 51 and is configured to engage with the fixed-side members 10 and 20. The engagement of the engaging portion 52 with the fixed-side members 10 and 20 restricts the range of movement of the movable housing 50 relative to the fixed housing 10.

[0157] As shown in Figure 12, the engaging portion 52 has a central portion 53 that protrudes downward from the fitting portion 51, and a pair of protruding portions 54 that protrude outward in the width direction from the lower part of the central portion 53.

[0158] When the movable housing 50 moves upward, the protruding portion 54 comes into contact with the upper limiting portion 24 of the fixing member 20. When the movable housing 50 moves downward, the protruding portion 54 comes into contact with the width wall portion 11c of the fixed housing 10. When the movable housing 50 moves in the width direction, the central portion 53 comes into contact with the upper limiting portion 24 of the fixing member 20. When the movable housing 50 moves in the front-back direction, the protruding portion 54 comes into contact with the vertical portion 22 of the fixing member 20.

[0159] The distance (Y-direction distance) from the tip of one protrusion 54 (+Y direction end) to the tip of the other protrusion 54 (-Y direction end) is the same as the width dimension of the fitting portion 51.

[0160] At the center of the width direction in the front of the central portion 53, a recessed area 52a is formed that is open to the front and downward. A portion of the signal terminals 30 and the shield terminals 40 are arranged in the recessed area 52a.

[0161] (Signal terminal 30) As shown in Figure 9, the signal terminal 30 has a substrate connection portion 31, a fixed-side retained portion 32, an intermediate elastic portion 33, a movable-side retained portion 34, a tip elastic portion 35, and a contact portion 36, in this order from the base end to the tip. The board connection section 31 is connected to the first board 91 by soldering or the like. The fixed-side retained portion 32 is held by the fixed housing 10. The fixed-side retained portion 32 is press-fitted into the fixed housing 10 from above. The intermediate elastic portion 33 is formed to be easily elastically deformable, allowing the movable side holding portion 34 to move relative to the fixed side holding portion 32. The movable side retained portion 34 is held by the movable housing 50. The movable side retained portion 34 is press-fitted into the movable housing 50 from below. The tip elastic portion 35 is formed to be easily elastically deformable, allowing the contact portion 36 to move relative to the movable side held portion 34. The contact portion 36 contacts the signal terminal 80 of the second connector 200, which is the object to be connected.

[0162] The intermediate elastic portion 33 has a first curved portion 33b that folds downward and a second curved portion 33d that folds upward. The intermediate elastic portion 33 also has a first straight portion 33a that extends upward and is located on the base end side of the first curved portion 33b, a second straight portion 33c that extends linearly and is located between the first curved portion 33b and the second curved portion 33d, and a third straight portion 33e that extends upward and is located on the tip side of the second curved portion 33d.

[0163] A slit 33s is formed in the intermediate elastic portion 33, extending in the direction in which the intermediate elastic portion 33 extends. The slit 33s is formed in the center of the intermediate elastic portion 33 in the width direction. The slit 33s is formed in a longer section that includes all sections of the first curved portion 33b, the second straight portion 33c, and the second curved portion 33d.

[0164] The average width dimension of the fixed-side retained portion 32 is greater than the width dimension of the intermediate elastic portion 33. The average width dimension of the movable side retained portion 34 is greater than the width dimension of the intermediate elastic portion 33. The intermediate elastic portion 33 has a constant width dimension along the direction of extension.

[0165] The signal terminals 30 are oriented perpendicular to the Y-direction in the thickness direction of the board, and perpendicular to the Y-direction in the width direction of the board.

[0166] (Shield terminal 40) As shown in Figures 10 and 11, the shield terminal 40 has a connection-side shield portion 41, a fixed-side shield portion 42, an intermediate shield portion 44, a movable-side shield portion 46, and a tip-side shield portion 47. The connection-side shield portion 41 shields the board connection portion 31 of the signal terminal 30. The fixed-side shield portion 42 shields the fixed-side retained portion 32 of the signal terminal 30. The intermediate shield section 44 shields the intermediate elastic section 33 of the signal terminal 30. The movable shield portion 46 shields the movable retained portion 34 of the signal terminal 30. The tip-side shield portion 47 shields the tip-side portions 35 and 36 of the signal terminal 30.

[0167] The connection-side shield portion 41 has a pair of connection-side lateral portions 41a that shield the board connection portion 31 of the signal terminal 30 from the outside in the width direction. The connection-side lateral portions 41a are oriented in the width direction with respect to the thickness direction. The connection-side shield portion 41 also functions as a board connection portion 41 that is connected to the first board 91.

[0168] The fixed-side shield portion 42 has a pair of fixed-side lateral portions 42a that shield the fixed-side retained portion 32 from both sides in the width direction, and fixed-side vertical portions 42b, 42b that shield the fixed-side retained portion 32 from the +X direction side, which is the thickness direction of the plate. The fixed-side lateral portion 42a and the fixed-side vertical portions 42b, 42b have their rolled surfaces facing the fixed-side held portion 32. The fixed-side shield portion 42 also functions as the shield fixed-side held portion 42 that is held by the fixed housing 10.

[0169] The intermediate shield portion 44 has a pair of intermediate lateral portions 44a, 44a that shield the intermediate elastic portion 33 from both sides in the width direction, and intermediate vertical portions 44b, 44b that shield the intermediate elastic portion 33 from the thickness direction. The intermediate lateral portion 44a and the intermediate vertical portions 44b, 44b have their rolled surfaces facing the intermediate elastic portion 33.

[0170] The movable side shield portion 46 has a pair of movable side lateral portions 46a that shield the movable side held portion 34 from both sides in the width direction, and a movable side vertical portion 46b that shields the movable side held portion 34 from the -X direction side, which is the thickness direction of the plate. The movable lateral portion 46a and the movable vertical portion 46b have their rolled surfaces facing the movable held portion 34.

[0171] The tip-side shield portion 47 has a pair of tip-side lateral portions 47a that shield the tip-side portions 35 and 36 from both sides in the width direction, and a tip-side vertical portion 47b that shields the tip-side portions 35 and 36 from the -X direction, which is the thickness direction of the plate. The tip-side lateral portion 47a and the tip-side vertical portion 47b have their rolled surfaces facing the tip-side portions 35 and 36.

[0172] The fixed-side shield portion 42 and the intermediate shield portion 44 are connected by a pair of fixed-side connecting portions 43. One fixed-side connecting portion 43 connects one fixed-side lateral portion 42a to one intermediate lateral portion 44a, and the other fixed-side connecting portion 43 connects the other fixed-side lateral portion 42a to the other intermediate lateral portion 44a. The fixed-side connecting portions 43 are formed to be narrow in width, making them easily elastically deformable.

[0173] The movable shield portion 46 and the intermediate shield portion 44 are connected by a pair of movable connecting portions 45. One movable connecting portion 45 connects one movable lateral portion 46a to one intermediate lateral portion 44a, and the other movable connecting portion 45 connects the other movable lateral portion 46a to the other intermediate lateral portion 44a. The movable connecting portions 45 are formed to be narrow in width, making them easily elastically deformable.

[0174] The distance in the width direction between a pair of fixed-side lateral portions 42a is greater than the distance in the width direction between a pair of intermediate lateral portions 44a, 44a. Therefore, each of the pair of fixed-side connecting portions 43 has a displacement portion 43h that is displaceable in the width direction. The displacement portion 43h of the fixed-side connecting portion 43 is formed at a position adjacent to the fixed-side lateral portion 42a on the fixed-side connecting portion 43. The distance in the width direction between a pair of movable side portions 46a is greater than the distance in the width direction between a pair of intermediate side portions 44a, 44a. Therefore, each of the pair of movable side connecting portions 45 has a displacement portion 45h that is displaceable in the width direction. The displacement portion 45h of the movable side connecting portion 45 is formed at a position adjacent to the movable side portion 46a on the movable side connecting portion 45.

[0175] The distance in the width direction between the pair of movable side portions 46a is greater than the distance in the width direction between the pair of fixed side portions 42a.

[0176] The fixed-side vertical sections 42b, 42b consist of one fixed-side vertical section 42b connected to one fixed-side lateral section 42a via a curved section, and the other fixed-side vertical section 42b connected to the other fixed-side lateral section 42a via a curved section.

[0177] An additional intermediate vertical section 44c, extending upward, is formed above one of the fixed vertical sections 42b. The additional intermediate vertical section 44c is located above the fixed lateral section 42a. Furthermore, the additional intermediate vertical section 44c is located above the curved section between one of the fixed vertical sections 42b and the other fixed lateral section 42a. An additional intermediate vertical section 44c, extending upward, is formed above the other fixed vertical section 42b. The additional intermediate vertical section 44c is located above the fixed lateral section 42a. Furthermore, the additional intermediate vertical section 44c is located above the curved section between the other fixed vertical section 42b and the other fixed lateral section 42a.

[0178] Each intermediate vertical section 44b consists of one intermediate vertical section 44b connected to one intermediate lateral section 44a via a curved section, and the other intermediate vertical section 44b connected to the other intermediate lateral section 44a via a curved section. The length of the intermediate lateral portion 44a (length along the direction of extension of the signal terminal 30) and the length of the intermediate vertical portion 44b are the same.

[0179] The movable vertical portion 46b is formed integrally. The movable vertical portion 46b is connected to one movable lateral portion 46a via a curved portion, and to the other movable lateral portion 46a via a curved portion.

[0180] A pair of tip-side lateral portions 47a extend upward from a pair of movable-side lateral portions 46a, and a tip-side vertical portion 47b extends upward from a movable-side vertical portion 46b. The tip-side portion 47a is formed to be narrow in width, making it easily elastically deformable. The tip of the tip-side portion 47a is a shield contact portion 47a1 that contacts the shield terminal 60 of the second connector 200.

[0181] The tip-side vertical portion 47b has a main body portion 47b1 and a base portion 47b2. The main body portion 47b1 of the tip-side vertical portion 47b is located on the -X side of the movable-side vertical portion 46b. The base portion 47b2 connects the movable-side vertical portion 46b and the main body portion 47b1 of the tip-side vertical portion 47b.

[0182] <Second connector 200> Next, we will explain the second connector 200.

[0183] As shown in Figures 13 to 16, the second connector 200 comprises a signal terminal 80, a housing 70, and a shield terminal 60. The second connector 200 is formed when the signal terminal 80 and the shield terminal 60 are held in the housing 70.

[0184] The second connector 200 comprises a base portion 201 and a tip portion 202 having a smaller cross-sectional area (cross-sectional area perpendicular to the Z direction) than the base portion 201. The base portion 201 constitutes the upper part of the second connector 200, and the tip portion 202 constitutes the lower part of the second connector 200. The tip portion 202 of the second connector 200 is inserted into the mating hole 51a of the first connector 100.

[0185] (Signal terminal 80) The signal terminal 80 consists of a first portion 82 extending linearly in the Z direction, a second portion 81 extending perpendicular to the Z direction, and a curved portion 83 connecting the first portion 82 and the second portion 81. The lower part 82b of the first portion 82 functions as a signal contact portion that contacts the signal terminal 30 of the first connector 100, and the second portion 81 functions as a board connection portion that connects to the second board 92.

[0186] The signal terminal 80 is manufactured by punching and bending a metal sheet. The signal terminal 80 is formed by bending only in the thickness direction of the sheet. The thickness direction of the signal terminal 80 is perpendicular to the Y direction.

[0187] (Housing 70) The housing 70 is a housing fixed to the second substrate 92 and is made of an insulator such as synthetic resin.

[0188] The housing 70 has a housing base 71 and a housing tip 72. The housing base 71 has a placement hole 74a in which the upper part 82a of the first part 82 of the signal terminal 80 is positioned. The housing tip 72 has a placement groove 74b in which the lower part 82b of the first part 82 of the signal terminal 80 is positioned.

[0189] The lateral surface 71c of the housing base 71 and the lateral surface 72c of the housing tip 72 form the same plane. The front-to-back dimension of the housing tip 72 is smaller than the front-to-back dimension of the housing base 71. The housing tip 72 is formed in a plate shape with the front-to-back direction as the thickness direction. The front surface 72a of the housing tip 72 is located behind the front surface 71a of the housing base 71, and the rear surface 72b of the housing tip 72 is located in front of the rear surface 71b of the housing base 71.

[0190] A pair of isolation walls 73 extending in the vertical direction are formed protruding from the rear surface 72b of the housing tip 72. The portion between the pair of isolation walls 73 is an arrangement groove 74b in which the lower part 82b of the first portion 82 of the signal terminal 80 is positioned.

[0191] The housing 70 has a press-fit portion 75 into which the press-fit portion 61a1 of the shield terminal 40 is press-fitted. The press-fit portion 75 is formed on the housing base 71. The press-fit portion 75 is formed to bulge out from the general surfaces 71a, 71b, and 71c of the housing base 71. Two grooves are formed in the press-fit portion 75 so that the two press-fit portions 61a1, 61a1 of the shield terminal 60 are press-fitted. The press-fit portion 75 is formed on the front surface 71a side of the housing base 71.

[0192] (Shield terminal) As shown in Figure 13, the shield terminal 60 is made by punching and bending a metal sheet. The shield terminal 60 has a shield base 61 and a shield tip 62. The shield base 61 covers the housing base 71, and the shield tip 62 covers the housing tip 72.

[0193] The shield base 61 has a pair of lateral portions 61c that cover a pair of lateral surfaces 71c of the housing base 71, front portions 61a, 61a that cover the front surface 71a of the housing base 71, and a rear portion 61b that covers the rear surface 71b of the housing base 71.

[0194] The front portions 61a, 61a of the shield base 61 have press-fit portions 61a1, 61a1 which are press-fitted into the press-fit portion 75 of the housing base 71. Specifically, the front portions 61a, 61a consist of one front portion 61a and the other front portion 61a. Press-fit portions 61a1 are formed in each of the front portions 61a and the other front portion 61a.

[0195] The shield terminal 40 has a plurality (four) of board connection portions 63. Two of the four board connection portions 63 extend from each of the pair of press-fit portions 61a1, and the other two board connection portions 63 extend from the rear portion 61b of the shield base portion 61.

[0196] The shield tip portion 62 has a front portion 62a that covers the front surface 72a of the housing tip portion 72, a rear portion 62b that covers the rear surface 72b of the housing tip portion 72, and a pair of lateral portions 62c that cover the lateral surfaces 72c of the housing tip portion 72.

[0197] As shown in Figures 15 and 16, the rear portions 62b, 62b of the shield tip 62 are separated in the width direction and consist of one rear portion 62b and the other rear portion 62b. A pair of isolation walls 73, 73 of the housing tip 72 are positioned between the one rear portion 62b and the other rear portion 62b. Each of the rear portions 62b, 62b of the shield tip 62 functions as a shield contact portion that contacts the shield terminal 40 of the first connector 100.

[0198] The housing tip 72 is covered by the shield tip 62, except for the gap between one rear portion 62b and the other rear portion 62b.

[0199] One side portion 61c of the shield base 61 is connected to one side portion 62c of the shield tip portion 62, and the other side portion 61c of the shield base 61 is connected to the other side portion 62c of the shield tip portion 62.

[0200] <Effects and Effects> Next, the effects and advantages of this embodiment will be described.

[0201] In this embodiment, the floating connector 100 comprises a fixed housing 10 fixed to the object to be attached 91, a movable housing 50 movable relative to the fixed housing 10, and a signal terminal 30. The signal terminal 30 has a fixed-side retained portion 32 held by the fixed housing 10, a movable-side retained portion 34 held by the movable housing 50, and an elastically deformable intermediate elastic portion 33 located between the fixed-side retained portion 32 and the movable-side retained portion 34. Here, the floating connector 100 includes a shield terminal 40 having an intermediate shield portion 44. The intermediate shield portion 44 shields the intermediate elastic portion 33. Therefore, the intermediate shield section 44 suppresses the increase in impedance of the intermediate elastic section 33.

[0202] Furthermore, in this embodiment, the shield terminal 40 has a shield fixed-side holding portion 42 held by the fixed housing 10, a shield movable-side holding portion 46 held by the movable housing 50, and an intermediate shield portion 44 located between the shield fixed-side holding portion 42 and the shield movable-side holding portion 46. Here, as shown in Figure 10, the shield terminal 40 has elastically deformable fixed-side connecting parts 43, 43 that connect the intermediate shield part 44 and the shield fixed-side holding part 42, and elastically deformable movable-side connecting parts 45, 45 that connect the intermediate shield part 44 and the shield movable-side holding part 46. Therefore, not only is the movement of the movable housing 50 relative to the fixed housing 10 permitted, but the movement of the intermediate shield portion 44 relative to both the fixed housing 10 and the movable housing 50 is also permitted.

[0203] Furthermore, in this embodiment, the fixed-side connecting portions 43, 43 and the movable-side connecting portions 45, 45 are narrower than the intermediate shield portion 44. As a result, the relatively narrow fixed-side connecting portions 43, 43 and movable-side connecting portions 45, 45 allow the movable housing 50 to move relative to the fixed housing 10, and the intermediate shield portion 44 to move relative to the fixed housing 10 and the movable housing 50, while the relatively wide intermediate shield portion 44 shields the intermediate elastic portion 33 of the signal terminal 30 over a wide area.

[0204] Furthermore, in this embodiment, the intermediate shield portion 44 shields the intermediate elastic portion 33 from two or more directions. Therefore, compared to an embodiment in which the intermediate shield portion 44 shields the intermediate elastic portion 33 from only one direction, the impedance of the intermediate elastic portion 33 can be significantly reduced.

[0205] Furthermore, in this embodiment, the intermediate shield portion 44 has one intermediate lateral portion 44a and the other intermediate lateral portion 44a that shield the intermediate elastic portion 33 from the +Y direction and the -Y direction. As a result, the intermediate elastic portion 33 is shielded from two opposing directions (both sides in the Y direction).

[0206] Furthermore, in this embodiment, the thickness direction of one intermediate lateral portion 44a and the other intermediate lateral portion 44a are oriented in the Y direction. As a result, the rolled surface of the intermediate lateral portion 44a faces the intermediate elastic portion 33, so that the intermediate lateral portion 44a is shielded over a wide area.

[0207] In the above embodiment, the intermediate shield portion 44 has an intermediate vertical portion 44b that shields the intermediate elastic portion 33 from a direction perpendicular to the Y direction. Therefore, the intermediate elastic portion 33 is shielded from a direction perpendicular to the Y direction. Although not shown in the figures, the intermediate shield portion 44 may have a pair of intermediate vertical portions that shield the intermediate elastic portion 33 from a direction perpendicular to the Y direction and sandwiching the intermediate elastic portion 33. In this case, the intermediate elastic portion 33 is shielded by the pair of intermediate vertical portions from a direction perpendicular to the Y direction and sandwiching the intermediate elastic portion 33. Although not shown in the diagram, the intermediate shield portion 44 may also include a cylindrical portion that surrounds the signal path formed by the intermediate elastic portion 33. In this case, the cylindrical portion shields the intermediate elastic portion from the direction surrounding the signal path. These modifications are feasible based on common technical knowledge.

[0208] Furthermore, in this embodiment, the thickness direction of the intermediate vertical portion 44b is perpendicular to the Y direction and faces the direction of the intermediate elastic portion. Therefore, the rolled surface of the intermediate vertical portion 44b faces the intermediate elastic portion 33, so the intermediate elastic portion 33 is shielded over a wide area. In this embodiment, the intermediate vertical sections 44b, 44b are composed of one intermediate vertical section 44b and the other intermediate vertical section 44b, and a small gap is formed between the one intermediate vertical section 44b and the other intermediate vertical section 44b. However, instead of this configuration in this embodiment, the one intermediate vertical section 44b and the other intermediate vertical section 44b may be crimped together. By crimping the one intermediate vertical section 44b and the other intermediate vertical section 44b together, the above-mentioned gap can be eliminated. Furthermore, the above-mentioned gap may become a large gap when the shield terminal 40 undergoes elastic deformation, but this problem can be solved by eliminating the gap by crimping as described above.

[0209] Furthermore, in this embodiment, since the intermediate elastic portion 33 is oriented in the Y direction in the plate width direction, one intermediate lateral portion 44a and the other intermediate lateral portion 44a shield one plate thickness surface and the other plate thickness surface of the intermediate elastic portion 33. In addition, the intermediate vertical portion 44b shields the rolled surface of the intermediate elastic portion 33.

[0210] Furthermore, in this embodiment, the shield terminal 40 has a fixed-side shield portion 42 that shields the fixed-side retained portion 32. Therefore, the increase in impedance of the fixed-side retained portion 32 is suppressed.

[0211] Furthermore, in this embodiment, the fixed-side shield portion 42 has one fixed-side lateral portion 42a and the other fixed-side lateral portion 42a that shield the fixed-side held portion 32 from the +Y direction and the -Y direction. As a result, the fixed-side held portion 32 is shielded from two opposing directions (both sides in the Y direction).

[0212] Furthermore, in this embodiment, the fixed-side shield portion 42 has a fixed-side vertical portion 42b that shields the fixed-side held portion 32 from a direction perpendicular to the Y direction. Therefore, the fixed-side held portion 32 is shielded from a direction perpendicular to the Y direction. In this embodiment, the fixed vertical portions 42b, 42b are composed of one fixed vertical portion 42b and the other fixed vertical portion 42b, and a gap is formed between the one fixed vertical portion 42b and the other fixed vertical portion 42b. However, instead of this configuration in this embodiment, the one fixed vertical portion 42b and the other fixed vertical portion 42b may be crimped together. By crimping the one fixed vertical portion 42b and the other fixed vertical portion 42b together, the above-mentioned gap can be eliminated.

[0213] Furthermore, in this embodiment, the intermediate shield portion 44 has an additional intermediate vertical portion 44c that shields the portion of the intermediate elastic portion 33 adjacent to the fixed-side retained portion 32 from a direction perpendicular to the Y direction. The additional intermediate vertical portion 44c extends from the fixed-side vertical portion 42b. Therefore, the portion of the intermediate elastic section adjacent to the fixed-side retained portion is shielded from a direction perpendicular to the Y direction.

[0214] Furthermore, in this embodiment, one fixed-side portion 42a is located on the +Y side than one intermediate-side portion 44a, and the other fixed-side portion 42a is located on the -Y side than the other intermediate-side portion 44a. Therefore, by shielding the fixed-side retained portion 32 and the intermediate elastic portion 33 from both sides in the Y direction, the impedance of the wide fixed-side retained portion 32 can be reduced while effectively reducing the impedance of the intermediate elastic portion 33.

[0215] Furthermore, in this embodiment, the shield terminal 40 has a movable side shield portion 46 that shields the movable side retained portion 34. Therefore, the impedance of the movable side retained portion 34 can be reduced.

[0216] Furthermore, in this embodiment, the movable side shield portion 46 has one movable side portion 46a and the other movable side portion 46a that shield the movable side held portion 34 from the +Y direction and the -Y direction. As a result, the movable side held portion 34 is shielded from both sides in the Y direction. Furthermore, in this embodiment, the movable side shield portion 46 has a movable side vertical portion 46b that shields the movable side held portion 34 from a direction perpendicular to the Y direction. Therefore, the movable side held portion 34 is shielded from a direction perpendicular to the Y direction. In particular, in this embodiment, the movable side retained portion 34 is shielded from both sides in the Y direction, as well as from a direction perpendicular to the Y direction.

[0217] Furthermore, in this embodiment, the shield terminal 40 has a tip-side shield portion 47 that shields the tip-side portions 35 and 36 of the signal terminal 30. This makes it possible to reduce the impedance of the tip-side portions 35 and 36.

[0218] Furthermore, in this embodiment, the tip portions 35 and 36 of the signal terminal 30 have a contact portion 36 and a tip elastic portion 35 that elastically supports the contact portion 36. This ensures that the contact pressure of the signal terminal 30 can be secured.

[0219] Furthermore, in this embodiment, the tip-side shield portion 47 has one tip-side lateral portion 47a and the other tip-side lateral portion 47a that shield the tip-side portions 35 and 36 from the +Y direction and the -Y direction. As a result, the tip-side portions 35 and 36 are shielded from both sides in the Y direction. Furthermore, in this embodiment, the tip-side shield portion 47 has a tip-side vertical portion 47b that shields the tip-side portions 35 and 36 from a direction perpendicular to the Y direction. Therefore, the tip-side portions 35 and 36 are shielded from a direction perpendicular to the Y direction. In particular, in this embodiment, the tip sides 35 and 36 are shielded from both sides in the Y direction and from a direction perpendicular to the Y direction.

[0220] Furthermore, in this embodiment, one side portion 47a on the tip side is formed with one shield contact portion 47a1 that contacts the object to be connected 200, and the other side portion 47a on the tip side is formed with the other shield contact portion 47a1 that contacts the object to be connected 200. Therefore, it is not necessary to form a shield contact portion 47a1 separately from the tip side shield portion 47.

[0221] Furthermore, in this embodiment, one tip-side portion 47a has one shield contact portion 47a1 and one shield tip elastic portion 47a that elastically supports the one shield contact portion 47a1, and the other tip-side portion 47a has the other shield contact portion 47a1 and the other shield tip elastic portion 47a that elastically supports the other shield contact portion 47a1. Therefore, contact pressure at the shield terminal 40 can be ensured.

[0222] Furthermore, in this embodiment, the Y-direction dimension of the tip-side vertical portion 47b is larger than the Y-direction dimension of the tip-side portions 35 and 36. As a result, the tip-side portions 35 and 36 are shielded over a wide area.

[0223] Furthermore, in this embodiment, the tip-side vertical portion 47b extends from the movable-side vertical portion 46b. Here, the tip-side vertical portion 47b has a main body portion 47b1 located at a position away from the movable-side vertical portion 46b in the X direction, and a base portion 47b2 that connects the main body portion 47b1 and the movable-side vertical portion 46b. Therefore, the movable vertical portion 46b can be brought closer to the movable held portion 34, and the distance between the tip portions 35, 36 of the signal terminal 30 and the tip vertical portion 47b can be secured.

[0224] Furthermore, in this embodiment, one movable side portion 46a is located on the +Y side than one intermediate side portion 44a, and the other movable side portion 46a is located on the -Y side than the other intermediate side portion 44a. Therefore, by shielding the movable side retained portion 34 and the intermediate elastic portion 33 from both sides in the Y direction, the impedance of the wide movable side retained portion 34 can be reduced while effectively reducing the impedance of the intermediate elastic portion 33.

[0225] Furthermore, in this embodiment, the distance in the Y direction between one movable side portion 46a and the other movable side portion 46a is greater than the distance in the Y direction between one intermediate side portion 44a and the other intermediate side portion 44a. Therefore, by shielding the movable side retained portion 34 and the intermediate elastic portion 33 from both sides in the Y direction, the impedance of the wide movable side retained portion 34 can be reduced while effectively reducing the impedance of the intermediate elastic portion 33.

[0226] Furthermore, in this embodiment, the shield terminal 40 has an intermediate shield portion 44, a fixed side shield portion 42, and a movable side shield portion 46. The intermediate shield portion 44 has one intermediate side portion 44a and the other intermediate side portion 44a, the fixed side shield portion 42 has one fixed side portion 42a and the other fixed side portion 42a, and the movable side shield portion 46 has one movable side portion 46a and the other movable side portion 46a. Therefore, the intermediate elastic portion 33, the fixed-side retained portion 32, and the movable-side retained portion 34 of the signal terminal 30 are shielded over a wide area, so that the impedance of the signal terminal 30 is properly matched.

[0227] Furthermore, in this embodiment, as shown in Figure 11, the pair of fixed-side connecting portions 43, 43 are located on both sides in the Y direction of the first straight portion 33a and the first curved portion 33b of the intermediate elastic portion 33, and the pair of movable-side connecting portions 45, 45 are located on both sides in the Y direction of the second curved portion 33d and the third straight portion 33e of the intermediate elastic portion. In other words, the fixed-side connecting portions 43, 43 have one fixed-side connecting portion 43 and the other fixed-side connecting portion 43 that shield the intermediate elastic portion 33 from the +Y direction and the -Y direction, and the movable-side connecting portions 45, 45 have one movable-side connecting portion 45 and the other movable-side connecting portion 45 that shield the intermediate elastic portion 33 from the +Y direction and the -Y direction. Therefore, the intermediate elastic portion 33 of the signal terminal 30 is also shielded by the fixed-side connecting portions 43, 43 and the movable-side connecting portions 45, 45, so that the impedance of the signal terminal 30 is matched more appropriately. Furthermore, in this embodiment, the intermediate elastic portion 33, the fixed-side held portion 32, and the movable-side held portion 34 are each shielded from a direction perpendicular to the Y direction by the intermediate vertical portions 44b, 44b, the fixed-side vertical portions 42b, 42b, and the movable-side vertical portion 46b, so that the impedance of the signal terminal 30 is matched more appropriately.

[0228] Next, the operational effects of this embodiment will be described from another perspective.

[0229] In this embodiment, the connector 200 includes a base portion 201 and a tip portion 202 that can be inserted into the fitting hole 51a of the mating connector 100 in the -Z direction. As shown in FIG. 13, the base portion 201 has an inner conductor portion 82a, an outer conductor portion 61 that surrounds the inner conductor portion 82a, and a dielectric portion 71 disposed between the inner conductor portion 82a and the outer conductor portion 61. Therefore, the impedance of the inner conductor portion 82a is matched.

[0230] As shown in FIG. 16, the tip portion 202 has a signal contact portion 82b that contacts the mating signal terminal 30 of the mating connector 100 and shield contact portions 62b, 62b that contact the mating shield terminal 40 of the mating connector 100. The signal contact portion 82b is connected to the inner conductor portion 82a, and the shield contact portions 62b, 62b are connected to the outer conductor portion 61. Therefore, when the tip portion 202 is inserted into the fitting hole 51a of the mating connector 100, the outer conductor portion 61 of the base portion 201 and the mating shield terminal 40 of the mating connector 100 are connected, and the inner conductor portion 82a of the base portion 201 and the mating signal terminal 30 of the mating connector 100 are connected.

[0231] Here, with respect to the cross-sectional area orthogonal to the -Z direction (the direction in which the tip portion 202 is inserted into the fitting hole 51a, hereinafter sometimes referred to as the insertion direction), the tip portion 202 is smaller than the base portion 201. In other words, the cross-sectional area of the tip portion 202 (the cross-sectional area orthogonal to the insertion direction) is smaller than the cross-sectional area of the base portion 201 (the cross-sectional area orthogonal to the insertion direction). Therefore, compared with an aspect in which the cross-sectional area of the tip portion 202 is the same as the cross-sectional area of the base portion 201, the cross-sectional area of the fitting hole 51a of the mating connector 100 (the cross-sectional area orthogonal to the insertion direction) can be made smaller. As a result, without reducing the cross-sectional area of the base portion 201, the portion (fitting portion 51) of the mating connector 100 in which the fitting hole 51a is formed can be miniaturized in a direction perpendicular to the insertion direction.

[0232] Furthermore, in this embodiment, the tip portion 202 is shaped to be hidden by the base portion 201 when viewed in the Z direction. Therefore, the connector 200 can be miniaturized in a direction perpendicular to the insertion direction.

[0233] Furthermore, in this embodiment, the tip portion 202 and the base portion 201 are adjacent in the Z direction. Therefore, the connector 200 can be made smaller compared to embodiments in which other structures exist between the tip portion 202 and the base portion 201.

[0234] Furthermore, in this embodiment, as shown in Figure 16, the dielectric portion 71 of the base 201 has an exposed surface 71d that is exposed so as to be able to face the mating connector 100. Therefore, the connector 200 can be made smaller compared to an embodiment in which another structure is interposed between the dielectric portion 71 of the base 201 and the mating connector 100.

[0235] Furthermore, in this embodiment, the signal contact portion 82b and the shield contact portions 62b, 62b are formed on the -X direction side of the tip portion 202. The shield contact portions 62b, 62b have one shield contact portion 62b and the other shield contact portion 62b located on the +Y direction side and the -Y direction side of the signal contact portion 82b. Therefore, the signal contact portion 82b is shielded from both sides in the Y direction.

[0236] Furthermore, in this embodiment, the tip portion 202 has a tip-side dielectric portion 72 and a tip-side outer conductor portion 62 that covers the outer surface of the tip-side dielectric portion 72. The tip-side outer conductor portion 62 has one and the other X-direction side portions 62a, 62b that cover the tip-side dielectric portion 72 from the +X direction and the -X direction, and one and the other Y-direction side portions 62c, 62c that cover the tip-side dielectric portion 72 from the +Y direction and the -Y direction. The shield contact portion 62b and the other shield contact portion 62b are formed on the other X-direction side portions 62a, 62b. As a result, the outer conductor portion 62 on the tip side is positioned to roughly surround the dielectric portion 72 on the tip side, which further reduces the impedance.

[0237] Next, the effects and advantages of this embodiment will be explained from yet another perspective.

[0238] In this embodiment, the connector 200 comprises a tip portion 202 that mates with the mating connector 100, and a base portion 201 that connects to the tip portion 202. The base portion 201 has a base-side inner conductor portion 82a, a cylindrical base-side outer conductor portion 61 that surrounds the base-side inner conductor portion 82a, and a base-side dielectric portion 71 disposed between the base-side outer conductor portion 61 and the base-side inner conductor portion 82a. Therefore, the impedance of the inner conductor portion 82a on the base side is matched.

[0239] Here, the tip portion 202 has a signal contact portion 82b connected to the base-side inner conductor portion 82a, and a tip-side dielectric portion 72 on which the signal contact portion 82b is positioned. The signal contact portion 82b is configured to contact the signal terminal 30 of the mating connector 100 on one side (the -X direction side) and to contact the tip-side dielectric portion 72 on the other side (the +X direction side). Therefore, even if the signal contact portion 82b comes into contact with and is pressed against the signal terminal 30 of the mating connector 100, the dielectric portion 72 on the tip side located behind it suppresses deformation of the signal contact portion 82b. In addition, since it is not necessary to clamp the signal contact portion 82b to the signal terminal 30 of the mating connector 100, it is easier to design the signal terminal 30 of the mating connector 100 to have a structure suitable for high-speed transmission.

[0240] Furthermore, in this embodiment, the tip portion 202 has shield contact portions 62b, 62b connected to the base-side outer conductor portion 61. The shield contact portions 62b, 62b are configured to contact the shield terminal 40 of the mating connector 100 on one side and to contact the tip-side dielectric portion 72 on the other side. Therefore, even if the shield contact portions 62b, 62b come into contact with and are pressed against the shield terminals 40 of the mating connector 100, the dielectric portion 72 on the tip side, located behind them, suppresses deformation of the shield contact portions 62b, 62b.

[0241] Next, the effects and advantages of this embodiment will be explained from yet another perspective.

[0242] Incidentally, a floating connector, such as the one described in Patent Document 2, is known. This floating connector connects to a mating connector that comprises an inner conductor portion, a cylindrical outer conductor portion surrounding the inner conductor portion, and a dielectric portion disposed between the inner and outer conductor portions. Specifically, a floating spring with contacts is connected to the inner conductor portion, and a pair of elastic contact pieces are connected to the outer conductor portion. However, in such floating connectors, a pair of highly flexible elastic contact pieces serve two functions: to accommodate misalignment and to make contact with the outer conductor. Therefore, as shown in Figure 12(b) of Patent Document 2, when the movable housing moves significantly, one of the elastic contact pieces separates from the outer conductor. As a result, the separated elastic contact piece may act like an antenna and become a source of noise.

[0243] In contrast, in this embodiment, the shield terminal 40 of the floating connector 100 has a shield movable side held portion 46 that is held by the movable housing 50, and an elastic support portion 47a that extends from the shield movable side held portion 46 and elastically supports the shield contact portions 62b, 62b that contact the outer conductor portion 60. Therefore, since a part of the shield terminal 40 (the shield movable side holding portion 46) moves together with the movable housing 50, even if the movable housing 50 moves significantly, the shield movable side holding portion 46 located on the base end side of the elastic support portion 47a moves together with the movable housing 50, thus preventing the shield contact portions 62b, 62b from separating from the outer conductor portion 60.

[0244] [Second Embodiment] Next, the first connector 100A and the second connector 200 according to the second embodiment will be described with reference to Figures 17 to 19. However, since the only difference between the second embodiment and the first embodiment is the structure of the intermediate shield portion of the first connector, the description of other parts will be omitted as appropriate.

[0245] As shown in FIG. 17, the first connector 100A according to the second embodiment includes a fixed housing 10, a movable housing 50, signal terminals 30, shield terminals 40A, and fixing members 20, 20.

[0246] As shown in FIGS. 18 and 19, the shield terminal 40A has an intermediate shield portion 44A. The intermediate shield portion 44A shields the intermediate elastic portion 33 of the signal terminal 30.

[0247] The intermediate shield portion 44A has a pair of intermediate side portions 44a, 44a that shield the intermediate elastic portion 33 from both sides in the width direction, and does not have an intermediate vertical portion 44b that shields the intermediate elastic portion 33 from the thickness direction. The pair of intermediate side portions 44a have their rolling surfaces facing the intermediate elastic portion 33.

[0248] [Third Embodiment] Next, with reference to FIGS. 20 to 35, the first connector 100B and the second connector 200B according to the third embodiment of the present disclosure will be described. However, the same or similar configurations as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate, and the points different from the first embodiment will be mainly described.

[0249] [First Connector 100B] As shown in FIG. 20, the first connector 100B is a floating connector. The first connector 100B includes a fixed housing 10, a movable housing 50, signal terminals 30, shield terminals 40, and a fixing member 20.

[0250] [Fixed Housing 10] The fixed housing 10 has a peripheral wall portion 11 and a bottom wall portion 12. The peripheral wall portion 11 has a front wall portion 11a, a rear wall portion 11b, and a pair of width wall portions 11c.

[0251] The fixed housing 10 holds the fixed-side holding portion 32 of the signal terminal 30. The fixed housing 10 holds the shield-fixing side retained portion 42 of the shield terminal 40. The fixed housing 10 holds the fixing members 20, 20.

[0252] As shown in Figures 21 and 22, the fixed housing 10 has a front-rear limiting portion 11d that restricts the range of movement of the movable housing 50 in the front-rear direction. The front-rear limiting portion 11d protrudes upward from the width wall portion 11c. The front-rear limiting portion 11d is formed at positions corresponding to the front and rear ends of each of the pair of width wall portions 11c. The front-rear limiting portion 11d is configured such that when the movable housing 50 moves in the front-rear direction, a part of the movable housing 50 (engaging portion 52) comes into contact with the front-rear limiting portion 11d.

[0253] (Fixing member 20) The fixing member 20 has a significantly different structure from that of the first embodiment.

[0254] As shown in Figure 21, the fixing member 20 (additional shield member) consists of a front member 20 and a rear member 20. The front member 20 and the rear member 20 have similar structures. Hereafter, unless otherwise specified, the front member 20 and the rear member 20 will be referred to as the fixing member 20.

[0255] As shown in Figure 21, the fixing member 20 has a pair of tail portions 21, a pair of side plate portions 23, 24, 25, and a connecting plate portion 27.

[0256] The pair of tail sections 21 are fixed to the first circuit board 91 by soldering or the like.

[0257] Each of the pair of side plate portions 23, 24, and 25 has a press-fit portion 23 that is press-fitted into the fixed housing 10. The press-fit portion 23 protrudes inward in the front-rear direction from the base portion 25 of the side plate portions 23, 24, and 25. Each of the pair of side plate portions 23, 24, and 25 has an upper limiting portion 24. The upper limiting portion 24 restricts the upward movement range of the movable housing 50. The upper limiting portion 24 protrudes inward in the front-rear direction from the base portion 25 of the side plate portions 23, 24, and 25. The upper limiting portion 24 is located above the press-fit portion 23.

[0258] The connecting plate section 27 connects the outer ends of the pair of side plate sections 23, 24, and 25 in the front-rear direction. The upper part of the connecting plate section 27 is connected to the upper part of the base section 25 of the side plate sections 23, 24, and 25 via a curved section.

[0259] The connecting plate portion 27 of the front member 20 shields the signal terminal 30 from the +X direction. In particular, in this embodiment, as will be described later, the shield terminal 40 does not have a fixed-side vertical portion (see fixed-side vertical portions 42b, 42b in Figure 10) that shields the fixed-side retained portion 32 from the +X direction (see Figure 24). For this reason, the connecting plate portion 27 of the front member 20 plays an important role. When viewed from the +X direction, the connecting plate portion 27 of the front member 20 is shaped to completely conceal the fixed-side holding portion 32 and the intermediate elastic portion 33 of the signal terminal 30.

[0260] The connecting plate portion 27 of the rear member 20 shields the signal terminal 30 from the -X side. In particular, in this embodiment, the intermediate vertical portions 44b, 44b of the intermediate shield portion 44 of the shield terminal 40 are positioned on the +X side relative to the intermediate elastic portion 33. Therefore, the shielding effect of the shield terminal 40 on the intermediate elastic portion 33 from the -X side is lower than in the first embodiment. For this reason, the connecting plate portion 27 of the rear member 20 plays an important role. -When viewed from the X-direction side, the connecting plate portion 27 of the rear member 20 is shaped to completely conceal the intermediate elastic portion 33 of the signal terminal 30.

[0261] (Movable housing 50) The movable housing 50 has a fitting portion 51 and an engaging portion 52.

[0262] (Signal terminal 30) The signal terminal 30 has a structure substantially similar to that of the signal terminal 30 of the connector 100 in the first embodiment. However, unlike the first embodiment, the slit 33s formed in the intermediate elastic portion 33 is separated into two slits in its extending direction. Specifically, as shown in Figure 28, it is separated at an intermediate position in the second linear portion 33c of the intermediate elastic portion 33. This improves the dimensional accuracy of the signal terminal 30.

[0263] (Shield terminal 40) As shown in Figure 24, the shield terminal 40 has a connection-side shield portion 41, a fixed-side shield portion 42, an intermediate shield portion 44, a movable-side shield portion 46, and a tip-side shield portion 47.

[0264] The connection-side shield portion 41 has a pair of connection-side lateral portions 41a that shield the board connection portion 31 of the signal terminal 30 from the outside in the width direction. The connection-side lateral portions 41a are oriented in the width direction with respect to the thickness direction. The connection-side shield portion 41 also functions as a board connection portion 41 that is connected to the first board 91.

[0265] The fixed-side shield portion 42 has a pair of fixed-side lateral portions 42a that shield the fixed-side retained portion 32 from both sides in the width direction. Unlike the first embodiment, the fixed-side shield portion 42 does not have a fixed-side vertical portion (see fixed-side vertical portions 42b, 42b in Figure 10) that shields the fixed-side held portion 32 from a direction perpendicular to the Y direction. This prevents interference with the board connection portion 31 of the signal terminal 30 when the shield terminal 40 is press-fitted into the movable housing 50. The fixed-side shield portion 42 also functions as the shield fixed-side held portion 42 that is held by the fixed housing 10.

[0266] The intermediate shield portion 44 has a pair of intermediate lateral portions 44a, 44a that shield the intermediate elastic portion 33 from both sides in the width direction, and intermediate vertical portions 44b, 44b that shield the intermediate elastic portion 33 from the plate thickness direction. Unlike the intermediate vertical sections 44b, 44b of the first embodiment (see Figure 10), the intermediate vertical sections 44b, 44b are positioned below the intermediate elastic section 33. This allows the press-fitting order of the signal terminals 30 and shield terminals 40 into the movable housing 50 to be such that the signal terminals 30 are pressed in first.

[0267] The width dimension of the movable side retained portion 34 (see Figure 23) of the signal terminal 30 is greater than the distance in the width direction between the intermediate lateral portions 44a, 44a-side of the pair of movable side connecting portions 45, which are greater than the displacement portion 45h. By increasing the width dimension of the movable side retained portion 34 of the signal terminal 30, the width dimension of the tip elastic portion 35 that follows the movable side retained portion 34 can also be increased, thereby increasing its elastic force. Furthermore, the distance in the width direction between the pair of intermediate lateral portions 44a, 44a is the same as the distance in the width direction between the portions of the pair of movable connecting portions 45 that are closer to the intermediate lateral portions 44a, 44a than to the displacement portion 45h.

[0268] Furthermore, a portion of the pair of movable side connecting portions 45, specifically the movable side lateral portions 46a, 46a side, is positioned in the same location in the front-to-back direction as the movable side retained portion 34 of the signal terminal 30 (see Figure 28). For this reason, the order in which the signal terminal 30 and the shield terminal 40 are pressed into the movable housing 50 is such that the signal terminal 30 comes first. If the order is reversed and the shield terminal 40 is pressed in first, the aforementioned portion of the pair of movable side connecting portions 45 will get in the way, making it impossible to press in the signal terminal 30. Also, if the order is reversed and the shield terminal 40 is pressed in first, the pair of movable side connecting portions 45 will get in the way, making it difficult to press in the movable side retained portion 34 of the signal terminal 30 from below.

[0269] Furthermore, the third linear portion 33e of the intermediate elastic portion 33 of the signal terminal 30 is positioned in the same location as the movable side holding portion 34 in the front-rear direction. Therefore, a portion of the pair of movable side connecting portions 45 is positioned in the same location as the third linear portion 33e of the intermediate elastic portion 33 of the signal terminal 30 in the front-rear direction. This allows the intermediate elastic portion 33 of the signal terminal 30 to be properly shielded by the pair of movable side connecting portions 45 of the shield terminal 40. In this embodiment, as shown in Figure 28, the second straight section 33c, the second curved section 33d, and the third straight section 33e of the intermediate elastic section 33 are completely hidden by the shield terminal 40 when viewed from the side.

[0270] The portion of the fixed-side connecting portion 43 adjacent to the fixed-side lateral portion 42a (the portion where the displacement portion 43h is formed in this embodiment) is positioned on the -X side of the fixed-side retained portion 32 of the signal terminal 30 (see Figure 28). This ensures that the fixed-side connecting portion 43 does not interfere with the press-fitting process when the fixed-side retained portion 32 is pressed into the fixed housing 10 from the +Z side.

[0271] The portion of the intermediate elastic portion 33 of the signal terminal 30 adjacent to the fixed-side retained portion 32 (for example, the first curved portion 33b) is not hidden by the fixed-side connecting portion 43 in a side view. However, in this embodiment, the side plate portions 23, 24, and 25 of the fixing member 20 hide the portion of the intermediate elastic portion 33 of the signal terminal 30 adjacent to the fixed-side retained portion 32 in a side view. As a result, the portion of the intermediate elastic portion 33 of the signal terminal 30 adjacent to the fixed-side retained portion 32 is sufficiently shielded from the +Y direction and the -Y direction.

[0272] As shown in Figure 30, the end of one intermediate vertical section 44b and the end of the other intermediate vertical section 44b are facing each other in the Y direction, and a certain gap is formed between them. This is because even if one were to form the shield terminal 40 to eliminate this gap, springback would cause a gap to form. However, a smaller gap is preferable from the viewpoint of shielding effectiveness. Therefore, in this embodiment, inclined end faces 44b1 are formed at the end of one intermediate vertical section 44b and the end of the other intermediate vertical section 44b that are opposite each other. The inclined end face 44b1 is an end face that is inclined with respect to the thickness direction of the intermediate vertical section 44b. The inclined end face 44b1 and the other inclined end face 44b1 are inclined in directions that are substantially parallel to each other. As a result, even if springback occurs, the gap between the end of one intermediate vertical section 44b and the end of the other intermediate vertical section 44b can be reduced. (The gap referred to here is the gap when viewed from the thickness direction of the pair of intermediate vertical sections 44b.) This is because, by forming the inclined end faces 44b1 as described above, in the bending process when forming the shield terminal 40 ("bent product"), the intermediate vertical section 44b and the other intermediate vertical section 44b can be bent until they partially overlap when viewed from the above direction. During the bending process, the parts can be bent until they partially overlap, which allows the gap between them to be reduced or eliminated after springback occurs. In this embodiment, in the manufacturing process of the shield terminal 40, the last part to bend is the pair of curved sections between the movable vertical section 46b and the pair of movable lateral sections 46a, 46a. Figure 29 shows the state immediately before the final bending process. However, the effects of the inclined end surface 44b1 described above are not limited to this case.

[0273] Unlike the first embodiment, the tip-side vertical portion 47b does not have a main body portion 47b1 (see Figure 10) located on the -X side of the movable-side vertical portion 46b. The entire tip-side vertical portion 47b is located in the same position as the movable-side vertical portion 46b in the X direction. However, the tip-side vertical portion 47b may be configured in the same manner as in the first embodiment.

[0274] <Second connector 200B> As shown in Figures 31 to 34, the second connector 200B includes a signal terminal 80, a housing 70, and a shield terminal 60.

[0275] (Signal terminal 80) The width dimension of the upper part 82a of the first part 82 of the signal terminal 80 is smaller than the width dimension of the lower part 82b. The width dimension of the upper part 82a referred to here means the width dimension of the part in which the press-fit protrusion 82a1, described later, is not formed. The upper part 82a is a part that is surrounded on all sides by the housing 70 and is therefore prone to impedance reduction. By reducing the width dimension of the upper part 82a as described above, excessive impedance reduction can be prevented.

[0276] The second section 81 and the curved section 83 have the same width dimension. The width dimension of the second section 81 and the curved section 83 is smaller than the lower part 82b of the first section 82 and larger than the upper part 82a.

[0277] Press-fit protrusions 82a1 are formed on the upper part 82a of the first portion 82 of the signal terminal 80. The press-fit protrusions 82a1 are formed at multiple different locations (three locations in the figure) in the direction in which the first portion 82 extends (up and down direction). The uppermost press-fit protrusion 82a1 is a part that does not bite into the housing 70 and functions as a press-fit shoulder for pushing the signal terminal 80 into the housing 70 when press-fitting the signal terminal 80 into the housing 70. The other press-fit protrusions 82a1 (the two lower locations) are the parts that bite into the housing 70.

[0278] The lowest press-fit projection 82a1 is located at the lower end of the upper part 82a. Therefore, the width dimension of the first part 82 changes at the lowest press-fit projection 82a1. The uppermost press-fit projection 82a1 is located at the upper end of the upper part 82a. As a result, the width dimension of the signal terminal 80 changes at the uppermost press-fit projection.

[0279] (Housing 70) The housing 70 has a protruding wall 76 that projects outward in the width direction from the lateral surface 71c of the housing base 71. This protruding wall 76 holds the shield terminal 60.

[0280] (Shield terminal 60) The shield terminal 60 has a shield base 61 and a shield tip 62. The shield base 61 covers the housing base 71, and the shield tip 62 covers the housing tip 72.

[0281] The shield base 61 has a pair of lateral portions 61c that cover a pair of lateral surfaces 71c of the housing base 71, a front portion 61a that covers the front surface 71a of the housing base 71, and a rear portion 61b that covers the rear surface 71b of the housing base 71.

[0282] The lateral portion 61c of the shield base 61 is held by the housing 70. Specifically, a notch 61c1 is formed in the lateral portion 61c, extending downward from its upper end. A protruding wall 76, which protrudes outward in the width direction from the lateral surface 71c of the housing base 71, is press-fitted into the notch 61c1.

[0283] The shield terminal 60 has a plurality (eight) of board connection portions 63. Two board connection portions 63 are formed on each of the pair of side portions 61c, front portion 61a, and rear portion 61b of the shield base portion 61. Unlike the first embodiment, the board connection portions 63 are connected to the board 92 with their end faces facing the board 92.

[0284] The shield tip portion 62 has a front portion 62a that covers the front surface 72a of the housing tip portion 72, and rear portions 62b, 62b that cover the rear surface 72b of the housing tip portion 72, but does not have a pair of lateral portions (see lateral portion 62c in Figure 14) that cover the lateral surface 72c of the housing tip portion 72.

[0285] As shown in Figure 33, the rear portions 62b, 62b of the shield tip 62 are separated in the width direction and consist of one rear portion 62b and the other rear portion 62b. A pair of isolation walls 73, 73 of the housing tip 72 are positioned between the one rear portion 62b and the other rear portion 62b. Each of the rear portions 62b, 62b of the shield tip 62 functions as a shield contact portion that contacts the shield terminal 40 of the first connector 100B.

[0286] The shield tip 62 has tip-side connecting portions 62d, 62d that connect the lower end of the front portion 62a and the lower end of the rear portion 62b. The tip-side connecting portions 62d, 62d cover the housing tip 72 from the -Z direction. The tip-side connecting portions 62d, 62d are formed by bending a plate material that will be used as the material for the shield terminal 40, and have a curved shape that is convex in the -Z direction. That is, the tip-side connecting portions 62d, 62d connect from the lower end of the front portion 62a to the lower end of the rear portion 62b in a curved shape. This allows the shield contact portion 47a1 that comes into contact with the tip-side connecting portions 62d, 62d to be smoothly displaced during connection. The tip-side connecting portions 62d, 62d are separated in the width direction, similar to the rear portions 62b, 62b.

[0287] As shown in Figure 34, the shield base 61 has an intermediate front connecting portion 61d that connects the front portion 61a of the shield base 61 to the front portion 62a of the shield tip 62, and an intermediate rear connecting portion 61e that connects the rear portion 61b of the shield base 61 to the rear portion 62b of the shield tip 62. Therefore, in this embodiment, unlike the first embodiment, the exposed surface (see exposed surface 71d in Figure 16) is covered by the shield terminal 60.

[0288] The shield terminal 60 has a cap recess 61c2. The cap recess 61c2 is a recess for attaching a cap to protect the connector 200 during transport, etc. Two cap recesses 61c2 are formed on each of the pair of lateral portions 61c of the shield base 61.

[0289] <Effects and Effects> Next, the effects and advantages of this embodiment will be described. However, the effects and benefits similar to those of the first embodiment, as well as the effects and benefits already described, will be omitted.

[0290] In this embodiment, as shown in Figures 23 to 25, the intermediate vertical portion 44b of the shield terminal 40 is positioned on the -Z direction side of the intermediate elastic portion 33. Therefore, when the shield terminal 40 is press-fitted into the movable housing 50 from the -Z direction side, the shield terminal 40 can be press-fitted into the movable housing 50 which is already holding the signal terminal 30.

[0291] Furthermore, in this embodiment, as shown in Figure 21, the floating connector 100B includes an additional shielding member 20. As shown in Figure 28, the additional shielding member 20 has a fixed-side vertical portion 27 that shields the fixed-side retained portion 32 from a direction perpendicular to the Y direction. Therefore, even if the shield terminal 40 does not have a fixed-side vertical portion or if the shielding effect of the fixed-side vertical portion of the shield terminal 40 is insufficient, the fixed-side held portion 32 can be shielded from a direction perpendicular to the Y direction.

[0292] Furthermore, in this embodiment, as shown in Figure 28, the additional shield member 20 (rear member 20) has a portion 27 (fixed vertical portion, connecting plate portion 27) that shields the intermediate elastic portion 33 from the -X direction side. Therefore, even if the shielding of the intermediate elastic portion 33 is insufficient with only the shield terminal 40, the shielding effect on the intermediate elastic portion 33 can be enhanced.

[0293] Furthermore, in this embodiment, as shown in Figure 30, the end 44b1 of one intermediate vertical section 44b and the end 44b1 of the other intermediate vertical section 44b are opposite each other in the Y direction. In this case, a smaller gap between the two is preferable from the standpoint of shielding effectiveness. Therefore, in this embodiment, the end portion 44b1 of one intermediate vertical portion 44b and the end portion 44b1 of the other intermediate vertical portion 44b are shaped such that, when viewed from the thickness direction of their plates, a portion of them overlap during the manufacturing process of the shield terminal 40. Therefore, the gap can be reduced by having the end portion 44b1 of one intermediate vertical portion 44b and the end portion 44b1 of the other intermediate vertical portion 44b overlap in part during the manufacturing process of the shield terminal 40, when viewed from the thickness direction of their plates.

[0294] Furthermore, in this embodiment, as shown in Figure 31 and the like, the connector 200B includes a signal terminal 80, a shield terminal 60, and a housing 70. The signal terminal 80 has an inner conductor portion 82a and a signal contact portion 82b formed on the base portion 201. The shield terminal 60 has an outer conductor portion 61 and a shield contact portion 62b formed on the base portion 201. The housing 70 has a base-side dielectric portion 71 which is the dielectric portion 71 of the base portion 201, and a tip-side dielectric portion 72 which constitutes a part of the tip portion 202. The shield terminal 60 has one and the other base-side X-direction portions 61a, 61b, and one and the other Tip side X direction part It has 62a and 62b. The shield terminal 60 is formed by bending a plate material.

[0295] Here, as shown in Figure 32, a carrier cutting portion 64 is formed at the +Z direction end of one base-side X-direction portion 61a, which is the portion connected to the carrier C during the manufacturing process of the shield terminal 60 (see Figure 35). When the bent portion of the shield terminal 60 is unfolded with reference to one base-side X-direction portion 61a (see Figure 35), one base-side X-direction portion 61a, one tip-side X-direction portion 62a, the other tip-side X-direction portion 62b, and the other base-side X-direction portion 61b are aligned in this order along the Z direction. Therefore, as shown in Figure 35, in the state before bending during the manufacturing process of the shield terminal 60, one base-side X-direction portion 61a, one tip-side X-direction portion 62a, the other tip-side X-direction portion 62b, and the other base-side X-direction portion 61b are arranged along a direction perpendicular to the feed direction of the carrier C. Thus, the shield terminal 60 can be formed from material with a small dimension in the feed direction of the carrier C. Therefore, the shield terminal 60 can be manufactured efficiently with respect to the dimensions of the material in the carrier feed direction.

[0296] Furthermore, in this embodiment, as shown in Figure 33, the shield terminal 60 is one of the Tip side X direction part The -Z-direction end of 62a and the other end Tip side X direction partIt has a tip-side connecting portion 62d that connects to the end of 62b on the -Z direction side. The tip-side connecting portion 62d is bent into a curved shape that is convex in the -Z direction when viewed from the Y direction. Therefore, when connecting connector 200B to mating connector 100B, even if the mating shield terminal 40 of mating connector 100B comes into contact with the tip-side connecting portion 62d, the other side where the shield contact portion 62b is formed... Tip side X direction part The mating shield terminal 40 can be smoothly guided to 62b.

[0297] Furthermore, in this embodiment, as shown in Figure 34, the shield terminal 60 has an intermediate connecting portion 61e. The intermediate connecting portion 61e is connected to the -Z direction end of the other base side X direction portion 61b and the other Tip side X direction part Connect to the +Z end of 62b. Therefore, the other base side X direction portion 61b and the other Tip side X direction part 62b is connected via a short route. Therefore, the current path formed by the shield terminal 60 is easily shortened. In particular, in this embodiment, the transmission path length of the shield terminal 60 and that of the signal terminal 80 are approximately the same, which can suppress the phase difference between the ground and the signal.
