[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-002869 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-181810 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present disclosure is to provide a terminal unit that is excellent in high-speed transmission performance. [Means for solving the problem]

[0005] A terminal unit according to a first aspect is a terminal unit that is attached to a shielded cable having an inner conductor, an outer conductor that shields the inner conductor, and a sheath that covers the outer conductor, and when the direction in which the tip of the shielded cable faces is referred to as one axial side, the terminal unit comprises an inner terminal that is electrically connected to the inner conductor, a dielectric member that houses the inner terminal, an external terminal that has a housing portion that houses the inner terminal and the dielectric member, and a conductive first additional member that is formed separately from the external terminal, and the external terminal comprises a conductive path-forming portion that forms a conductive path between the housing portion and the outer conductor, and the first additional member comprises a conductive path-forming portion that forms a conductive path between the housing portion and the outer conductor, and the conductive path-forming portion of the external terminal and the conductive path-forming portion of the first additional member face each other across the inner conductor.

[0006] In this aspect, the terminal unit is attached to a shielded cable having an inner conductor, an outer conductor that shields the inner conductor, and a sheath that covers the outer conductor. The terminal unit includes an inner terminal electrically connected to the inner conductor, a dielectric member that houses the inner terminal, and an outer terminal having a housing that houses the inner terminal and the dielectric member.

[0007] In this aspect, the external terminal includes a conductive path-forming portion that forms a conductive path between the accommodating portion and the external conductor. The terminal unit also includes a conductive first additional member that is formed separately from the external terminal. The first additional member includes a conductive path-forming portion that forms a conductive path between the accommodating portion and the external conductor. The conductive path-forming portion of the external terminal and the conductive path-forming portion of the first additional member face each other across the internal conductor. Therefore, the conductive path-forming portion of the external terminal and the conductive path-forming portion of the first additional member can form a pair of conductive paths that face each other across the internal conductor, thereby achieving a terminal unit with excellent high-speed transmission performance.

[0008] In the embodiment described below, the conductive path-forming portion of the external terminal forms a conductive path between the housing portion and the first shield portion and also forms a conductive path between the housing portion and the second shield portion. However, this aspect is not limited to this. For example, the conductive path-forming portion of the external terminal may form only the conductive path between the housing portion and the second shield portion. In the embodiment described below, the terminal unit is assembled by placing the dielectric member inside the body of the housing from a direction perpendicular to the front-to-rear direction (opening direction) with the lid of the housing open, and then closing the lid. However, the terminal unit of this embodiment is not limited to this. In the embodiment described below, the terminal unit includes a second additional member, but the present aspect is not limited to this. In the embodiment described below, the dielectric member includes a first component and a second component that are assembled in a direction perpendicular to the axial direction, but the present aspect is not limited to this.

[0009] A terminal unit according to a second aspect is the terminal unit of the first aspect, wherein the terminal unit comprises a conductive second additional member formed separately from the external terminal, the second additional member comprising a conductive path forming portion that forms a conductive path between the accommodating portion and the external conductor, the conductive path forming portion of the first additional member and the conductive path forming portion of the second additional member facing each other across the internal conductor, and the conductive path forming portion of the second additional member being located radially inward of the conductive path forming portion of the external terminal.

[0010] In this aspect, the terminal unit includes a conductive second additional member formed separately from the external terminal. The second additional member includes a conductive path-forming portion. The conductive path-forming portion of the second additional member forms a conductive path between the housing portion and the external conductor. The conductive path-forming portion of the first addition member and the conductive path-forming portion of the second addition member face each other across the internal conductor, and the conductive path-forming portion of the second addition member is located radially inward of the conductive path-forming portion of the external terminal. Therefore, the conductive path-forming portion of the first additional member and the conductive path-forming portion of the second additional member can form a pair of conductive paths that face each other with the internal conductor in between. Compared to an embodiment in which the second additional member is not provided, it is easier to make the pair of conductive paths have the same or similar structures, thereby improving high-speed transmission performance.

[0011] A terminal unit according to a third aspect is the terminal unit of the second aspect, wherein the conductive path-forming portion of the first addition member and the conductive path-forming portion of the second addition member have the same shape.

[0012] In this aspect, the conductive path-forming portion of the first addition member and the conductive path-forming portion of the second addition member have the same shape. Therefore, the conductive paths formed by the conductive path-forming portions of the first additional member and the conductive paths formed by the conductive path-forming portions of the second additional member can have the same structure, thereby improving high-speed transmission performance.

[0013] In the embodiment described below, the first addition member and the second addition member have the same shape, but the present aspect is not limited to this.

[0014] In the terminal unit according to a fourth aspect, in the second aspect, the first addition member and the second addition member have the same shape.

[0015] In this embodiment, the first addition member and the second addition member have the same shape. Therefore, it is possible to use common components for the first addition member and the second addition member.

[0016] The terminal unit according to the fifth aspect is the terminal unit according to the first to fourth aspects, wherein the dielectric member comprises a first component member that is assembled to the internal terminal from one side in an assembly direction that is perpendicular to the axial direction, and a second component member that is assembled to the internal terminal from the other side in the assembly direction.

[0017] In this aspect, the dielectric member comprises a first component member that is assembled to the internal terminal from one side in an assembly direction that is perpendicular to the axial direction, and a second component member that is assembled to the internal terminal from the other side in the assembly direction. Therefore, the internal terminal can be assembled to the dielectric member in a direction perpendicular to the axial direction, making the internal terminal less susceptible to buckling and facilitating the assembly of the terminal unit.

[0018] In the embodiment described below, the first component member is integrated with the first additional member. However, the first component member of this embodiment is not limited to this. In other words, when assembling the terminal unit, the first component member and the first additional member may be handled separately. The same applies to the relationship between the second component member and the second additional member. Furthermore, the terminal unit of this embodiment does not necessarily have to include the second additional member.

[0019] A terminal unit according to a sixth aspect is the terminal unit of the fifth aspect, wherein the first component member and the second component member have the same shape.

[0020] In this embodiment, the first component and the second component have the same shape. Therefore, it is possible to use common parts between the first and second constituent members.

[0021] A terminal unit according to a seventh aspect is the terminal unit of the fifth or sixth aspect, wherein the first addition member is integrated with the first component member.

[0022] In this embodiment, the first addition member is integrated with the first component member. Therefore, the first addition member and the first component member can be handled as a single unit, which makes it easier to assemble the terminal unit.

[0023] In the embodiment described below, the first addition member is integrated with the first component member by being integrally molded (insert molded) with the first component member. However, this aspect is not limited to this. The first addition member may be integrated with the first component member by being press-fitted into the first component member, or may be integrated with the first component member by being adhered to the first component member with an adhesive.

[0024] The terminal unit according to the eighth aspect is the terminal unit of the second aspect, wherein the dielectric member comprises a first component member that is assembled to the internal terminal from one side in an assembly direction that is perpendicular to the axial direction, and a second component member that is assembled to the internal terminal from the other side in the assembly direction, and the first additional member is integrated with the first component member, and the second additional member is integrated with the second component member.

[0025] In this embodiment, the first addition member is integral with the first component member, and the second addition member is integral with the second component member. Therefore, the first addition member and the first component member can be handled as a single unit, and the second addition member and the second component member can be handled as a single unit, which makes it easier to assemble the terminal unit.

[0026] In the embodiment described below, the second additional member is integrated with the second component member by being integrally molded (insert molded) with the second component member. However, this aspect is not limited to this. The second additional member may be integrated with the second component member by being press-fitted into the second component member, or may be integrated with the second component member by being adhered to the second component member with an adhesive. The same applies to the relationship between the first component member and the first additional member.

[0027] A terminal unit according to a ninth aspect is the terminal unit of the eighth aspect, wherein the first additional member and the second additional member have the same shape, and the first component member and the second component member have the same shape.

[0028] In this aspect, the first addition member and the second addition member have the same shape, and the first component member and the second component member have the same shape. Therefore, it is possible to standardize parts not only between the first addition member and the second addition member, but also between the first component member and the second component member.

[0030] Hereinafter, preferred embodiments of a terminal unit and a connector including the same according to the present disclosure will be described.

[0031] (Connector 10) FIG. 1 is a perspective view of the connector 10, and FIG. 2 is an exploded perspective view of the connector 10. As shown in FIG.

[0032] In each figure, arrow X indicates the front direction of the connector, arrow Y indicates one side (left side) in the width direction of the connector, and arrow Z indicates the upper direction of the connector.

[0033] As shown in FIGS. 1 and 2, the connector 10 includes a housing 12 and a plurality of terminal units 14A, 14B housed in the housing 12.

[0034] The terminal units 14A, 14B are made up of a plurality of first terminal units 14A (coaxial terminal units) and a plurality of second terminal units 14B (differential terminal units). Hereinafter, when no particular distinction is made, they will be simply referred to as terminal units 14.

[0035] As shown in FIG. 2, the housing 12 has unit accommodating sections 12a that accommodate the terminal units 14. The unit accommodating sections 12a are configured so that the terminal units 14 can be inserted from the rear of the connector. A plurality of unit accommodating sections 12a are provided in two rows, one above the other. Some of the unit accommodating sections 12a accommodate first terminal units 14A, and others accommodate second terminal units 14B, and these sections have different structures. The types of terminal units 14 accommodated in the region on one side of the housing 12 in the connector width direction are different from those accommodated in the region on the other side of the connector width direction.

[0036] The housing 12 has a locking operation portion 12b. The locking operation portion 12b is a portion for maintaining the connection between the connector 10 and the mating connector (connection object, not shown). The connection between the connector 10 and the mating connector can be released by pressing down the locking operation portion 12b and displacing the claw portion. The locking operation portion 12b is formed on the upper part of the housing 12.

[0037] The connector 10 has a locking portion fixing member 16 . When the locking portion fixing member 16 is attached to the housing 12, the locking operation portion 12b is prevented from bending, thereby preventing the connector 10 from being released from the connected state with the mating connector.

[0038] The connector 10 includes a retaining member 18 . With the retaining member 18 attached, the terminal unit 14 is prevented from slipping out of the unit accommodating portion 12a toward the rear of the connector. The retaining member 18 is inserted into the housing 12 from the outside in the connector width direction.

[0039] (First terminal unit 14A) Next, the first terminal unit 14A will be described.

[0040] In each figure, arrow X indicates the front direction of the unit (one axial direction), arrow Y indicates the upward direction of the unit, and arrow Z indicates one widthwise direction. That is, the first terminal unit 14A is disposed with its widthwise direction facing the vertical direction of the connector. Hereinafter, when the terms "front-rear direction," "up-down direction," and "widthwise direction" are used simply, they refer to the front-rear direction, up-down direction, and widthwise direction of the terminal unit 14.

[0041] As shown in FIG. 3, the first terminal unit 14A is attached to a first shielded cable 90A having one inner conductor 91a.

[0042] FIG. 9 is a cross-sectional view of the first shielded cable 90A.

[0043] The first shielded cable 90A includes an insulated wire 91, an outer conductor 92, and a sheath 93 in this order from the center.

[0044] The insulated wire 91 has, in order from the center, an inner conductor 91a and an insulator 91b. The inner conductor 91a is, for example, a twisted wire made up of a plurality of single wires.

[0045] The outer conductor 92 has, in order from the center, a first shielding portion 92a and a second shielding portion 92b. The first shielding portion 92a is a conductive film, such as an aluminum tape. The second shielding portion 92b is a braided wire.

[0046] The first terminal unit 14A includes an internal terminal 20A, a dielectric member 30 that houses the internal terminal 20A, an external terminal 40 that is electrically connected to the external conductor 92, a conductive first additional member 50A, and a conductive second additional member 50B.

[0047] The dielectric member 30 is composed of a first component member 31A that is assembled to the internal terminal 20A from above, and a second component member 31B that is assembled to the internal terminal 20A from below. The first component member 31A is integrally molded with the first additional member 50A, and the second component member 31B is integrally molded with the second additional member 50B.

[0048] The first terminal unit 14A is assembled as follows. (1) The crimping portion 24 of the inner terminal 20A is crimped onto the inner conductor 91a of the first shielded cable 90A that has been subjected to terminal processing (see FIG. 3). (2) The first component member 31A integrated with the first additional member 50A is assembled to the first shielded cable 90A and the internal terminal 20A from above, and the second component member 31B integrated with the second additional member 50B is assembled from below (see FIG. 4). (3) The internal terminal 20A, the dielectric member 30, etc. are arranged from above the external terminal 40 in the open state. (4) The accommodating portion 41, the first fastening portion 43 and the second fastening portion 45 of the external terminal 40 are deformed to be in a closed state (see FIG. 5).

[0049] The first shielded cable 90A to which the termination has been applied has the following configuration. As shown in Fig. 6, the tip end portion of the second shield part 92b is folded back so as to cover a cylindrical reinforcing member 95. Hereinafter, this folded back portion will be referred to as a folded back portion 92b1. The reinforcing member 95 is disposed radially outward from the unfolded portion of the second shield part 92b and radially inward from the folded back portion 92b1 of the second shield part 92b. The front end of the sheath 93 faces the rear end of the reinforcing member 95 in the front-rear direction. The reinforcing member 95 is made of, for example, metal. The first shield part 92a is not folded back, and a portion of the first shield part 92a near the tip is exposed from the sheath 93 and the second shield part 92b. Hereinafter, this exposed portion will be referred to as an exposed part 92a1. The front end of the first shield part 92a and the front end of the insulator 91b are positioned in the same position in the front-to-rear direction.

[0050] (Internal terminal 20A) FIG. 7 shows an enlarged view of the internal terminal 20A.

[0051] The internal terminal 20A is a member that is connected to the internal conductor 91a of the first shielded cable 90A. The internal terminal 20A is manufactured by bending a metal plate into a cylindrical shape, for example. The internal terminal 20A has a structure that is approximately symmetrical in the width direction (Z direction).

[0052] In the following description of the internal terminal 20A, the radial direction refers to a direction perpendicular to an imaginary central axis AX that passes through the center of the internal terminal 20A and is parallel to the front-to-rear direction of the unit, and the radially outward direction refers to a radial direction away from the central axis AX.

[0053] The internal terminal 20A includes a contact portion 21, a cylindrical portion 22, a connecting portion 23, a crimping portion 24, and an impedance adjusting portion 25, in this order from the front side to the rear side.

[0054] The contact portion 21 is a portion that comes into contact with a signal terminal (not shown) of a mating connector. The contact portion 21 has a pair of contact pieces 21a. The pair of contact pieces 21a come into contact with the signal terminal of the mating connector so as to sandwich the connection object (the signal terminal of the mating connector) from the width direction.

[0055] The cylindrical portion 22 is a portion formed by bending a plate material into a cylindrical shape. The cross section of the cylindrical portion 22 perpendicular to the front-rear direction is circular. The ends of the plate material are butted together at a position above the unit (+Y direction side) of the cylindrical portion 22. Locking holes 22a are formed in the cylindrical portion 22. Locking protrusions 34 (see FIG. 6) of the dielectric member 30 are inserted into the locking holes 22a, thereby restricting relative movement of the internal terminals 20A in the front-rear direction relative to the dielectric member 30. The locking holes 22a are formed in two locations, one on the top surface side (+Y direction side) and one on the bottom surface side (-Y direction side, see FIG. 6) of the cylindrical portion 22.

[0056] The connecting portion 23 is a portion that connects the tubular portion 22 and the crimping portion 24. Specifically, the connecting portion 23 connects the lower portion of the tubular portion 22 and the lower portion of the crimping portion 24 in the front-to-rear direction. The cross-sectional shape of the connecting portion 23 (cross-sectional shape perpendicular to the front-to-rear direction) is a substantially arc shape.

[0057] The crimping portion 24 is a portion that is crimped to the inner conductor 91a of the first shielded cable 90A.

[0058] The crimping portion 24 has a bottom plate portion 24a and a pair of crimping pieces 24b. The crimping portion 24 is crimped to the internal conductor 91a, thereby electrically connecting the internal conductor 91a and the internal terminal 20A. The crimping portion 24 has a substantially uniform cross-sectional structure along the front-rear direction. The width dimension of the crimping portion 24 is greater than the width dimension of the tubular portion 22.

[0059] The impedance adjusting portion 25 protrudes rearward from the bottom plate portion 24a of the crimping portion 24. The impedance adjusting portion 25 is composed only of an axially extending portion 25a. The axially extending portion 25a is located at the same position in the up-down direction as the bottom plate portion 41a of the crimping portion 24. The axially extending portion 25a is a carrier cutting portion. The carrier cutting portion is the portion that is cut last and separated from the carrier when manufacturing an internal terminal by progressive processing.

[0060] (Dielectric member 30, first additional member 50A, second additional member 50B) A space for accommodating the internal terminal 20A is formed inside the dielectric member 30, which is composed of the first component member 31A and the second component member 31B.

[0061] The first component 31A and the second component 31B share common components. In other words, the first component 31A and the second component 31B are made of the same material (dielectric) and have the same structure. The only difference between the first component 31A and the second component 31B is their position and orientation. Hereinafter, when no particular distinction is made, they will simply be referred to as component 31.

[0062] The first additional member 50A and the second additional member 50B share common components. In other words, the first additional member 50A and the second additional member 50B are made of the same material (conductive material) and have the same structure. The first additional member 50A and the second additional member 50B are the same as the first component member 31A and the second component member 31B except for their arranged positions and orientations. Hereinafter, when no particular distinction is made, they will simply be referred to as additional members 50.

[0063] The first component member 31A and the second component member 31B face each other in the vertical direction across the center of the first terminal unit 14A, and the first addition member 50A and the second addition member 50B face each other in the vertical direction across the center of the first terminal unit 14A.

[0064] Hereinafter, the vertical direction may be referred to as the facing direction. Furthermore, the vertical direction toward the center of the first terminal unit 14A may be referred to as the inner facing direction, and the vertical direction away from the center of the first terminal unit 14A may be referred to as the outer facing direction.

[0065] The component 31 is resin-molded by insert molding using the additional member 50 as an insert component. As a result, the component 31 is integrated with the additional member 50. Therefore, when assembling the first terminal unit 14A, the component 31 and the additional member 50 can be handled as a single unit.

[0066] The component 31 has a recess 32 and a protrusion 33. The recess 32 and the protrusion 33 fit together, thereby fixing the first component 31A and the second component 31B together.

[0067] The component 31 has locking projections 34. The locking projections 34 protrude inward in the opposing direction and are inserted into upper and lower locking holes 22a (see FIG. 6) of the internal terminal 20A.

[0068] As shown in FIG. 8, the additional member 50 includes a first connecting portion 51, a second connecting portion 52, and a linking portion 53.

[0069] As shown in FIG. 6, the first connection portion 51 is connected to the receiving portion 41 of the external terminal 40 . Specifically, the outer surfaces of the first connecting portions 51 of the first addition member 50A in the opposing direction come into contact with the pair of lid portions 41c1 of the storage portion 41. The outer surfaces of the first connecting portions 51 of the second addition member 50B in the opposing direction come into contact with the bottom plate portion 41a of the storage portion 41.

[0070] The first connecting portion 51 has a flat plate shape with its thickness oriented in the opposing direction. The radially outer surface of the first connecting portion 51 is exposed and not covered by the resin of the component 31, while the other surface of the first connecting portion 51 is covered by the resin of the component 31.

[0071] The first connecting portion 51 has a pair of through holes 51a. The through holes 51a are holes through which the locked portions 47 of the lid portion 41c1, which will be described later, pass.

[0072] The second connection portion 52 is connected to the outer conductor 92 . Specifically, the second connection portion 52 comes into contact with an exposed portion 92a1, which is an exposed portion of the first shield portion 92a of the outer conductor 92, from the outside in the opposing direction.

[0073] The second connecting portion 52 has a cross-sectional shape of an arc that is convex outward in the opposing direction. The second connecting portion 52 has a front portion 52a that is narrower and a rear portion 52b that is wider.

[0074] The connecting portion 53 connects the rear end of the first connecting portion 51 and the front end of the second connecting portion 52. The rear end of the first connecting portion 51 is located outward of the front end of the second connecting portion 52 in the opposing direction.

[0075] The connecting portion 53 has a vertical portion 53a extending generally parallel to the opposing direction, thereby reducing the distance in the front-rear direction between the rear end of the first connecting portion 51 and the front end of the second connecting portion 52. In the front-rear direction, the position of the connecting portion 53 generally coincides with the position of the rear end of the crimping portion 24 of the internal terminal 20A.

[0076] As a result, the first connecting portion 51, the second connecting portion 52, and the linking portion 53 of the additional member 50 form a conductive path between the accommodating portion 41 and the first shield portion 92a of the outer conductor 92. Hereinafter, the first connecting portion 51, the second connecting portion 52, and the linking portion 53 may be referred to as conductive path forming portions 51, 52, 53.

[0077] The first addition member 50A has a pair of widthwise lateral extension portions 54. The pair of lateral extension portions 54 have the same structure.

[0078] The lateral extension portion 54 extends outward in the width direction from the rear end portion of the first connection portion 51 .

[0079] The lateral extension portion 54 has a first extension portion 54a and a second extension portion 54b. The first extending portion 54a extends outward in the width direction from the first connecting portion 51 and then extends inward in the opposing direction. The second extending portion 54b extends rearward from the first extending portion 54a and then extends inward in the width direction.

[0080] The outer side surface in the width direction of the first extending portion 54a is exposed and not covered with the resin of the component 31, but the other surface of the first extending portion 54a is covered with the resin of the component 31.

[0081] Most of both surfaces of the second extending portion 54b in the plate thickness direction are covered with the resin of the component 31. As a result, the second extending portion 54b functions to increase the holding force of the component 31 to the additional member 50. The second extending portion 54b also functions to narrow the opening on the rear side of the accommodating portion 41.

[0082] The additional member 50 also includes a carrier disconnecting portion 59 that protrudes rearward from the rear end of the second connecting portion 52 .

[0083] (External terminal 40) The external terminals 40 are manufactured by bending a metal plate material or the like.

[0084] The external terminal 40 includes a housing portion 41 , a first connecting portion 42 , a first fastening portion 43 , a second connecting portion 44 , and a second fastening portion 45 .

[0085] The storage section 41 has main body sections 41a and 41b each having a shape that opens upward (opening direction). Specifically, the main body portions 41a and 41b have a generally U-shaped cross section that opens upward (opening direction). The main body portions 41a and 41b are composed of a bottom plate portion 41a whose thickness direction is oriented in the vertical direction and a pair of side plate portions 41b whose thickness direction is oriented in the width direction.

[0086] The container 41 also has a pair of lids 41c1. The pair of lid portions 41c1 extend from the upper ends of the pair of side plate portions 41b. The pair of lid portions 41c1 form a top plate portion 41c whose thickness direction is oriented in the up-down direction. The top plate portion 41c closes the space between the upper ends of the pair of side plate portions 41b. The front end of the top plate portion 41c is located rearward of the front ends of the main body portions 41a and 41b.

[0087] FIG. 4 shows the pair of lid portions 41c1 in an open state. When the pair of lid portions 41c1 are in an open state, no curved portion is formed between the lid portion 41c1 and the side plate portion 41b. When the lid portion 41c1 is in an open state, the dielectric member 30 is allowed to be placed inside the main body portions 41a, 41b from above (the opening direction). A notch 46 extending in the front-rear direction is formed on the inner surface in the width direction of the portion between the lid portion 41c1 and the side plate portion 41b.

[0088] The first connecting portion 42 connects the lower portion of the storage portion 41 and the lower portion of the first tightening portion 43. The first connecting portion 42 has a generally U-shaped or C-shaped cross section that is open upward from its front end to its rear end. The width dimension of the lower portion of the first tightening portion 43 is smaller than the width dimension of the lower portion of the storage portion 41. In addition, the lower end of the first tightening portion 43 is located above the lower end of the storage portion 41.

[0089] The first tightening portion 43 tightens the exposed portion 92a1 of the first shield portion 92a, the second connecting portion 52 of the first addition member 50A, and the second connecting portion 52 of the second addition member 50B. The first tightening portion 43 has a substantially circular cross-sectional shape in the closed state.

[0090] The second connecting portion 44 connects the lower portion of the first tightening portion 43 and the lower portion of the second tightening portion 45 together. The second connecting portion 44 has a generally C-shaped cross section that is open upward from its front end to its rear end. The width dimension of the lower portion of the second tightening portion 45 is greater than the width dimension of the lower portion of the first tightening portion 43. The lower end of the second tightening portion 45 is located lower than the lower end of the first tightening portion 43.

[0091] The second tightening portion 45 tightens the portion of the first shielded cable 90A where the cylindrical reinforcing member 95 is provided. Specifically, the second tightening portion 45 tightens the cylindrical reinforcing member 95 and a folded portion 92b1 of the second shield portion 92b that is folded back to cover the reinforcing member 95. In the closed state, the second tightening portion 45 has a substantially circular cross-sectional shape that is larger than the first tightening portion 43.

[0092] Each of the pair of cover portions 41c1 has a locking portion 47. The locked portion 47 is a portion that is locked to the dielectric member 30 housed in the housing portion 41. Specifically, the locked portion 47 is pressed into the locking recess 35 of the dielectric member 30, thereby being locked to the dielectric member 30. The locking recess 35 is opened upward by the through-hole 51a of the first connecting portion 51 of the first addition member 50A.

[0093] The pair of side plate portions 41b of the accommodation portion 41 are provided with guide protrusions 41b1 that protrude inward in the width direction. The guide protrusions 41b1 fit into the guide recesses 36 of the dielectric member 30. This positions the dielectric member 30 relative to the accommodation portion 41.

[0094] The guide protrusions 41b1 and the locked portions 47 are positioned in the same front-rear direction, so that the locked portions 47 pass through the guide recesses 36 of the dielectric member 30 when the dielectric member 30 is disposed inside the main body portions 41a and 41b.

[0095] The top plate portion 41c of the accommodation portion 41 is configured to come into contact with the first connecting portion 51 of the first addition member 50A. Specifically, the inner ends in the width direction of the pair of lid portions 41c1 are configured to come into contact with the first connecting portion 51 of the first addition member 50A. The curved portion 41d between the side plate portion 41b and the lid portion 41c1 is bent at an angle of 90 degrees or more.

[0096] The bottom plate portion 41a of the accommodation portion 41 comes into contact with the first connecting portion 51 of the second addition member 50B. Specifically, the bottom plate portion 41a has a pair of protruding portions 41a1 that come into contact with the first addition member 50A. Note that one of the pair of protruding portions 41a1 is hidden in FIG. 4. The pair of protruding portions 41a1 are aligned in the width direction and each extend in the front-rear direction.

[0097] The first connecting portion 42 and the first tightening portion 43 of the external terminal 40 form a conductive path between the accommodating portion 41 and the first shield portion 92a of the external conductor 92. Furthermore, the first connecting portion 42, the first tightening portion 43, the second connecting portion 44, and the second tightening portion 45 of the external terminal 40 form a conductive path between the accommodating portion 41 and the second shield portion 92b of the external conductor 92. The first connecting portion 42 and the first tightening portion 43 are sometimes referred to as conductive path-forming portions 42, 43, and the first connecting portion 42, the first tightening portion 43, the second connecting portion 44, and the second tightening portion 45 are sometimes referred to as conductive path-forming portions 42, 43, 44, 45.

[0098] (Second terminal unit 14B) Next, the second terminal unit 14B will be described with reference to FIGS. The same components as those of the first terminal unit 14A are denoted by the same reference numerals and the description thereof will be omitted as appropriate, and only the parts that differ from the first terminal unit 14A will be described.

[0099] Similar to the first terminal unit 14A, the second terminal unit 14B is disposed with its width direction oriented in the vertical direction of the connector.

[0100] The second terminal unit 14B is attached to a second shielded cable 90B (see FIG. 10) having two inner conductors 91a.

[0101] FIG. 15 is a cross-sectional view of the second shielded cable 90B.

[0102] The second shielded cable 90B has two insulated wires 91. The two insulated wires 91 are twisted together. The outer conductor 92 is provided to shield the two insulated wires 91.

[0103] The second terminal unit 14B includes two internal terminals 20B, a dielectric member 30 that houses the two internal terminals 20B, an external terminal 40 that is electrically connected to the external conductor 92, a conductive first additional member 50A, and a conductive second additional member 50B.

[0104] The dielectric member 30 is composed of a first component member 31A that is assembled to the internal terminal 20B from above, and a second component member 31B that is assembled to the internal terminal 20B from below. The first component member 31A is integrally molded with the first additional member 50A, and the second component member 31B is integrally molded with the second additional member 50B.

[0105] The second terminal unit 14B is assembled as follows. (1) The crimping portions 24 of the two inner terminals 20B are crimped onto the two inner conductors 91a of the second shielded cable 90B that has been subjected to terminal processing. (2) The first component member 31A integrated with the first additional member 50A is assembled from above to the second shielded cable 90B and the two internal terminals 20B, and the second component member 31B integrated with the second additional member 50B is assembled from below. (3) The internal terminal 20B, the dielectric member 30, etc. are arranged from above the external terminal 40 (not shown) in the open state. (4) The accommodating portion 41, the first clamping portion 43 and the second clamping portion 45 of the external terminal 40 are deformed to be in a closed state.

[0106] In the second shielded cable 90B that has been subjected to terminal processing, the front end of the first shield portion 92a is located rearward of the front ends of the insulators 91b of the two insulated wires 91.

[0107] (internal terminal 20B) FIG. 13 shows an enlarged view of the internal terminal 20B of the second terminal unit 14B.

[0108] In the internal terminal 20B, the impedance adjusting portion 25 has a radially extending portion 25b extending radially outward and an axially extending portion 25a extending axially. In this embodiment, the radially extending portion 25b extends radially outward in a direction inclined toward the other axial side. The axially extending portion 25a is a carrier disconnection portion.

[0109] (Dielectric member 30, first additional member 50A, second additional member 50B) In the second terminal unit 14B, the first component member 31A and the second component member 31B share common parts, and the first additional member 50A and the second additional member 50B share common parts. Hereinafter, when no particular distinction is made, they will simply be referred to as component member 31 and additional member 50.

[0110] In the second terminal unit 14B as well, the component member 31 is resin-molded by insert molding using the additional member 50 as an insert component.

[0111] FIG. 14 shows the additional member 50 of the second terminal unit 14B.

[0112] As shown in FIG. 14, the additional member 50 includes a first connecting portion 51, a second connecting portion 52, and a linking portion 53.

[0113] 14, the first connecting portion 51 has a flat plate shape with its thickness direction facing the opposing direction. The radially outer surface of the first connecting portion 51 is exposed and not covered by the resin of the component 31, and the other surfaces of the first connecting portion 51 are covered by the resin of the component 31.

[0114] A pair of side portions 55 are provided on both sides in the width direction of the first connecting portion 51. The first connecting portion 51 and the pair of side portions 55 constitute front portions 51, 55 of the additional member 50. The front portions 51, 55 have a substantially U-shaped cross section that is open inward in the opposing direction.

[0115] The second connecting portion 52 has a cross-sectional shape of an arc that is convex outward in the opposing direction. The second connecting portion 52 has the same width dimension from the front end to the rear end.

[0116] The connecting portion 53 connects the rear ends of the front portions 51, 55 to the front end of the second connecting portion 52. The cross section of the front end of the connecting portion 53 is substantially U-shaped, and the cross section of the rear end of the front portion 53b is arc-shaped.

[0117] The connecting portion 53 has a front portion 53b, a middle portion 53c, and a rear portion 53d. The cross-sectional shape of the front end of the front portion 53b is approximately U-shaped, and the cross-sectional shape of the rear end of the front portion 53b is arc-shaped. The middle portion 53c and the rear portion 53d have arc-shaped cross-sectional shapes. The cross-sectional size of the middle portion 53c does not change from front to back.

[0118] The connecting portion 53 has a generally U-shaped or arc-shaped (generally C-shaped) cross section that opens inward in the facing direction from the front end to the rear end. This improves high-speed transmission performance. In particular, with the second shielded cable 90B, the distance in the front-to-rear direction from the front end of the first shield portion 92a to the front end of the insulator 91b tends to be large due to the relationship with the two twisted insulated electric wires 91. For this reason, the above-described structure of the connecting portion 53 is effective.

[0119] 12 and 14, the coupling portion 53 does not have a vertical portion (see vertical portion 53a in FIG. 6) that extends substantially parallel to the opposing direction. In the second terminal unit 14B, the distance in the front-to-rear direction between the rear end of the first connecting portion 51 and the front end of the second connecting portion 52 is greater than that of the first terminal unit 14A. In the front-rear direction, the position of the front portion 53b of the connecting portion 53 substantially coincides with the position of the rear end of the crimping portion 24 of the internal terminal 20B.

[0120] <Action and effect> Next, the effects of this embodiment will be described.

[0121] Hereinafter, when describing the effects common to the first terminal unit 14A and the second terminal unit 14B, they will be described as the effects of the terminal unit 14. Furthermore, when there is no need to distinguish between the internal terminals 20A and 20B, they will simply be referred to as the internal terminals 20.

[0122] 2, the terminal unit 14 is attached to a shielded cable 90 (see FIGS. 9 and 15) having an inner conductor 91a, an outer conductor 92 that shields the inner conductor 91a, and a sheath 93 that covers the outer conductor 92. As shown in FIGS. 3 and 10, the terminal unit 14 includes an inner terminal 20 that is electrically connected to the inner conductor 91a, a dielectric member 30 that houses the inner terminal 20, and an outer terminal 40 that has a housing portion 41 that houses the inner terminal 20 and the dielectric member 30.

[0123] 3 and 10, the terminal unit 14 includes a conductive first addition member 50A formed separately from the external terminal 40. As shown in FIGS. 6 and 12, the first addition member 50A has a first connection portion 51 that connects to the accommodating portion 41 and a second connection portion 52 that connects to the external conductor 92. Therefore, the accommodating portion 41 of the external terminal 40 and the external conductor 92 can be electrically connected by the first addition member 50A.

[0124] In this embodiment, the second connection portion 52 of the first addition member 50A comes into contact with an exposed portion 92a1 of the outer conductor 92 that is exposed from the sheath 93, as shown in FIGS. Therefore, the first additional member 50A is not inserted between the sheath 93 and the outer conductor 92 (see the sleeve in Patent Document 1), and therefore assembly efficiency is good.

[0125] In this embodiment, as shown in FIGS. 3 and 10, the second connecting portion 52 of the first addition member 50A is disposed so as to cover the exposed portion 92a1 from the radially outer side perpendicular to the axial direction. Therefore, the arrangement of the first addition member 50A is easy.

[0126] In this embodiment, as shown in FIGS. 4 and 11, the terminal unit 14 includes a first fastening portion 43 that fastens the second connecting portion 52 and the exposed portion 92a1 of the first addition member 50A. Therefore, the first tightening portion 43 can ensure contact between the second connection portion 52 of the first addition member 50A and the exposed portion 92a1 of the outer conductor 92.

[0127] In this embodiment, the first tightening portion 43 is provided as a part of the external terminal 40, as shown in FIGS. Therefore, compared to a configuration in which the first tightening portion 43 is provided as a separate member from the external terminal 40, the number of parts can be reduced.

[0128] In this embodiment, as shown in FIGS. 8 and 14, the second connecting portion 52 of the first addition member 50A has an arcuate cross-sectional shape. Therefore, the cross-sectional shape of the shielded cable 90 can be prevented from being distorted by the fastening force of the first fastening portion 43.

[0129] 9 and 15, the outer conductor 92 includes a first shield portion 92a and a second shield portion 92b provided radially outward of the first shield portion 92a. As shown in FIGS. 3 and 10, the exposed portion 92a1 is a portion of the first shield portion 92a that is exposed from the sheath 93 and the second shield portion 92b. 6 and 12, the external terminal 40 includes a second tightening portion 45. The second tightening portion 45 tightens the reinforcing member 95 and a folded portion 92b1 of the second shield portion 92b that is folded back to cover the reinforcing member 95. For this reason, the tip side of the second shield portion 92b is folded back so as to cover the reinforcing member 95, and this folded back portion (folded back portion 92b1) and the reinforcing member 95 are fastened by the second tightening portion 45. The reinforcing member 95 functions to prevent the cross-sectional shape of the shielded cable 90 from being deformed when the folded back portion 92b1 is fastened by the second tightening portion 45. Furthermore, when the folded back portion 92b1 of the second shield portion 92b is firmly sandwiched between the reinforcing member 95 and the second tightening portion 45, the external terminal 40 and the shielded cable 90 will not separate even if the shielded cable 90 is pulled. As a result, it is possible to prevent a decrease in high-speed transmission performance due to a change in the cross-sectional shape of the shielded cable 90, and to achieve a strong fixation between the external terminal 40 and the shielded cable 90.

[0130] 3 and 10, in this embodiment, the terminal unit 14 includes a conductive second additional member 50B formed separately from the external terminal 40. As shown in FIGS. 6 and 12, the second additional member 50B has a first connecting portion 51 that connects to the accommodating portion 41, and a second connecting portion 52 that connects to the external conductor. Therefore, the accommodating portion 41 of the external terminal 40 and the external conductor 92 can be electrically connected by the second additional member 50B.

[0131] In this embodiment, the second connection portion 52 of the second addition member 50B comes into contact with an exposed portion 92a1 of the outer conductor 92 that is exposed from the sheath 93. Therefore, the second additional member 50B is not inserted between the sheath 93 and the outer conductor 92 (see the sleeve in Patent Document 1), and therefore assembly efficiency is good.

[0132] 4 and 10, the housing 41 includes main body portions 41a and 41b and a pair of lid portions 41c1. The main body portions 41a and 41b have a shape that opens in an opening direction that is perpendicular to the axial direction. In the open state, the lid portion 41c1 allows the dielectric member 30 to be placed inside the main body portions 41a and 41b from the opening direction, and in the closed state, the lid portion 41c1 covers the dielectric member 30 placed inside the main body portions 41a and 41b from the opening direction. Therefore, first, with lid portion 41c1 in an open state, dielectric member 30 is placed inside main body portions 41a and 41b from a direction perpendicular to the axial direction (opening direction), and then lid portion 41c1 is closed, so that lid portion 41c1 can cover dielectric member 30 placed inside main body portions 41a and 41b from the opening direction. Therefore, for example, since there is no need to insert dielectric member 30 into accommodating portion 41 from one axial side or the other axial side, assembling dielectric member 30 into accommodating portion 41 becomes easy.

[0133] 4 and 11, the cover portion 41c1 includes a locked portion 47. The locked portion 47 is locked to the held members 30, 50 held in the holding portion 41 when the cover portion 41c1 is closed. Therefore, when springback occurs, the locked portion 47 can prevent the held members 30, 50 and the lid portion 41c1 from separating from each other.

[0134] In the present embodiment, the terminal unit 14 includes a conductive first addition member 50A that is formed separately from the external terminals 40. The first addition member 50A has a first connection portion 51 that connects to the accommodation portion 41. The first connection portion 51 of the first addition member 50A is accommodated in the accommodation portion 41. Therefore, the impedance can be adjusted by the first connecting portion 51 of the first addition member 50A. Furthermore, with the lid portion 41c1 in an open state, the first connecting portion 51 of the first addition member 50A can be arranged inside the main body portions 41a, 41b from a direction perpendicular to the axial direction (opening direction), and then the lid portion 41c1 can be closed, thereby allowing the first connecting portion 51 of the first addition member 50A to be accommodated in the accommodation portion 41. Therefore, for example, since there is no need to insert the first addition member 50A into the accommodation portion 41 from the other axial side, the arrangement of the first addition member 50A in the accommodation portion 41 becomes easier.

[0135] Furthermore, in this embodiment, the first connecting portion 51 of the first addition member 50A comes into contact with the pair of lid portions 41c1 in the closed state. Therefore, the pair of lid portions 41c1 can be used to electrically connect the accommodation portion 41 and the first addition member 50A.

[0136] In this embodiment, the terminal unit 14 also includes a conductive second addition member 50B that is formed separately from the external terminals 40. The second addition member 50B has a first connection portion 51 that connects to the accommodation portion 41. The first connection portion 51 of the second addition member 50B is accommodated in the accommodation portion 41. Therefore, the impedance can be adjusted by the first connecting portion 51 of the second addition member 50B. Furthermore, with the lid portion 41c1 in an open state, the first connecting portion 51 of the second addition member 50B can be placed inside the main body portions 41a, 41b from a direction perpendicular to the axial direction (opening direction), and then the lid portion 41c1 can be closed, thereby allowing the first connecting portion 51 of the second addition member 50B to be housed in the housing portion 41. Therefore, for example, there is no need to insert the second addition member 50B into the housing portion 41 from the other axial side, making it easier to place the second addition member 50B in the housing portion 41.

[0137] Furthermore, in this embodiment, the first connecting portion 51 of the second addition member 50B comes into contact with the bottom plate portion 41a of the main body portions 41a, 41b. Therefore, the bottom plate portion 41a of the main body portions 41a, 41b can be used to electrically connect the accommodation portion 41 and the second addition member 50B.

[0138] 6 and 12, in this embodiment, the external terminal 40 includes conductive path-forming portions 42, 43, 44, and 45 that form a conductive path between the accommodating portion 41 and the external conductor 92. The terminal unit 14 also includes a conductive first addition member 50A that is formed separately from the external terminal 40. The first addition member 50A includes conductive path-forming portions 51, 52, and 53 that form a conductive path between the accommodating portion 41 and the external conductor 92. The conductive path-forming portions 42, 43, 44, and 45 of the external terminal 40 and the conductive path-forming portions 51, 52, and 53 of the first addition member 50A face each other across the internal conductor 91a. Therefore, a pair of conductive paths facing each other across the internal conductor 91a can be formed by the conductive path-forming portions 42, 43, 44, and 45 of the external terminal 40 and the conductive path-forming portions 51, 52, and 53 of the first additional member 50A, resulting in a terminal unit 14 with excellent high-speed transmission performance.

[0139] 6 and 12, the terminal unit 14 includes a conductive second additional member 50B formed separately from the external terminal 40. The second additional member 50B includes conductive path forming portions 51, 52, and 53 that form a conductive path between the accommodating portion 41 and the external conductor 92. The conductive path-forming portions 51, 52, and 53 of the first addition member 50A and the conductive path-forming portions 51, 52, and 53 of the second addition member 50B face each other across the internal conductor 91a. The conductive path-forming portions 51, 52, and 53 of the second addition member 50B are located radially inward of the conductive path-forming portions 42, 43, 44, and 45 of the external terminal 40. Therefore, a pair of conductive paths facing each other across the internal conductor 91a can be formed by the conductive path-forming portions 51, 52, and 53 of the first additional member 50A and the conductive path-forming portions 51, 52, and 53 of the second additional member 50B. Compared to an embodiment in which the second additional member 50B is not provided, it is easier to make the pair of conductive paths have the same or similar structures, thereby improving high-speed transmission performance.

[0140] In this embodiment, as shown in FIGS. 8 and 14, the conductive path-forming portions 51, 52, and 53 of the first addition member 50A and the conductive path-forming portions 51, 52, and 53 of the second addition member 50B have the same shape. For this reason, the conductive paths formed by the conductive path-forming portions 51, 52, and 53 of the first addition member 50A and the conductive paths formed by the conductive path-forming portions 51, 52, and 53 of the second addition member 50B can have the same structure, thereby improving high-speed transmission performance.

[0141] In this embodiment, as shown in FIGS. 8 and 14, the first addition member 50A and the second addition member 50B have the same shape. Therefore, it is possible to use common parts for the first addition member 50A and the second addition member 50B.

[0142] In addition, in this embodiment, as shown in Figures 3 and 10, the dielectric member 30 comprises a first component member 31A that is assembled to the internal terminal 20 from one side in the opposing direction, which is a direction perpendicular to the axial direction, and a second component member 31B that is assembled to the internal terminal 20 from the other side in the opposing direction. Therefore, the internal terminals 20 can be assembled to the dielectric member 30 in a direction perpendicular to the axial direction (facing direction), making the internal terminals 20 less likely to buckle and facilitating the assembly of the terminal unit 14.

[0143] In this embodiment, the first addition member 50A is integrated with the first component member 31A. Therefore, the first addition member 50A and the first component member 31A can be handled as a single unit, which makes it easier to assemble the terminal unit.

[0144] In this embodiment, the second addition member 50B is integrated with the second component member 31B. Therefore, the second addition member 50B and the second component member 31B can be handled as a single unit, which makes it easier to assemble the terminal unit.

[0145] In this embodiment, the first addition member 50A and the second addition member 50B have the same shape, and the first component member 31A and the second component member 31B have the same shape. Therefore, it is possible to standardize parts not only between the first addition member 50A and the second addition member 50B, but also between the first component member 31A and the second component member 31B.

[0146] [Supplementary explanation of the above embodiment] While the preferred embodiments of the connector of the present disclosure have been described above, the present disclosure is not limited thereto. The following description is provided as a supplementary explanation.

[0147] In the above embodiment, the impedance adjusting portion 25 of the internal terminal 20 of the first terminal unit 14A (coaxial terminal unit) does not have the radially extending portion 25b, and the impedance adjusting portion 25 of the internal terminal 20 of the second terminal unit 14B (differential terminal unit) has the radially extending portion 25b. However, the present disclosure is not limited to this.

[0148] In the above embodiment, the internal terminal 20 includes the impedance adjusting portion 25 connected to the crimping portion 24. This increases the capacitance of the crimping portion 24 and reduces the impedance of the crimping portion 24. However, the internal terminal of the present disclosure is not limited to this.

[0149] In the above embodiment, the storage unit 41 includes main body portions 41a and 41b and a pair of lid portions 41c1. The pair of lid portions 41c1 form the top plate portion 41c. However, the top plate portion may be formed by a single lid portion instead of the pair of lid portions 41c1. [Explanation of symbols]
