Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the jack connector and the plug connector described in Patent Document 1 are configured such that the jack-side outer contact and the cylindrical portion are connected in a state where they overlap in the radial direction. Therefore, there is room for improvement from the viewpoint of reducing the size of the connection portion between the jack connector and the plug connector in the radial direction (the direction intersecting the connection axis).

[0005] In view of the above facts, it is an object of the present invention to provide a connector and a connector set capable of reducing the size of the body in the direction intersecting the connection axis.

Means for Solving the Problems

[0006] The connector according to the first aspect includes an inner terminal having a connection portion connected to the inner conductor portion, a terminal-side covering portion that covers the inner terminal in a state where the connection portion protrudes outward, and a terminal-side extending portion that extends from the terminal-side covering portion and extends along the connection portion. The outer terminal includes a terminal-side dielectric provided between the inner terminal and the outer terminal and inside the terminal-side covering portion for supporting the inner terminal.

[0007] The connector according to the first aspect includes an inner terminal, an outer terminal, and a terminal-side dielectric. The outer terminal includes a terminal-side covering portion that covers the inner terminal in a state where the connection portion of the inner terminal protrudes outward, and a terminal-side extending portion that extends from the terminal-side covering portion and extends along the connection portion. In this configuration of the connector, a part of the mating connector connected to the connector and the terminal-side extending portion can cover the connection portion between the inner conductor portion and the connection portion of the inner terminal. In this configuration, in order to cover the connection portion between the inner conductor portion and the connection portion of the inner terminal, it is not necessary to overlap and arrange the outer terminal and a part of the mating connector in a direction intersecting the connection direction of the inner conductor portion and the connection portion of the inner terminal (the direction intersecting the connection axis). Thereby, the size of the connector in the direction intersecting the connection axis can be reduced.

[0008] The connector according to the second aspect is the connector according to the first aspect, wherein the outer terminal includes a first terminal forming plate formed of a metal plate and a second terminal forming plate formed of a metal plate, and the terminal-side covering portion is formed by the first terminal forming plate and the second terminal forming plate.

[0009] In the connector according to the second aspect, the outer terminal having a terminal-side covering portion can be formed at low cost by the first terminal forming plate and the second terminal forming plate.

[0010] The connector according to the third aspect has a plurality of the inner terminals in the connector according to the second aspect, and the outer terminal includes a single first terminal forming plate and a plurality of second terminal forming plates. Between the single first terminal forming plate and the plurality of second terminal forming plates, a plurality of terminal-side covering portions covering the plurality of inner terminals are formed respectively.

The first terminal forming plate includes a first side plate portion extending from the first main board portion toward the second main board portion side, and the second terminal forming plate includes a second side plate portion extending from the second main board portion toward the first main board portion side. The terminal-side covering portion is formed by the first main board portion, the second main board portion, and at least one of the first side plate portion and the second side plate portion.

[0013] In the connector according to the fourth aspect, the terminal-side covering portion is formed by the first main board portion, the second main board portion, and at least one of the first side plate portion and the second side plate portion. In this configuration, for example, a terminal-side covering portion corresponding to an inner terminal having a bent or curved shape can be easily formed.

[0014] The connector according to the fifth aspect includes an inner conductor portion connected to the inner terminal, an outer conductor portion having a conductor portion-side covering portion that covers the inner conductor portion and has a notch formed in an outer peripheral portion on the side where the inner terminal is connected, and a conductor portion-side dielectric provided between the inner conductor portion and the outer conductor portion and inside the conductor portion-side covering portion, supporting the inner conductor portion, and having a part of its outer periphery exposed at the notch.

[0015] The connector according to the fifth aspect includes an inner conductor portion, an outer conductor portion, and a dielectric on the conductor portion side. The outer conductor portion includes a conductor portion side covering portion that covers the inner conductor portion and has a notch formed in the outer peripheral portion on the side to which the inner terminal is connected. Further, a part of the outer periphery of the dielectric on the conductor portion side is exposed at the notch. In the configuration of this connector, a part of the mating connector connected to the connector can be arranged along the notch. Thereby, the connection portion between the inner conductor portion and the inner terminal can be covered by a part of the mating connector and the outer conductor portion. In this configuration, in order to cover the connection portion between the inner conductor portion and the inner terminal, it is not necessary to overlap the outer conductor portion and a part of the mating connector in a direction (connection axis crossing direction) crossing the connection direction between the inner conductor portion and the inner terminal. Thereby, the size reduction of the connector in the connection axis crossing direction can be achieved.

[0016] The connector set according to the sixth aspect includes a first connector that is a connector according to any one of the first to fourth aspects, and a second connector that is a connector according to the fifth aspect. In a state where the first connector is connected to the second connector, the connection portion of the inner terminal is connected to the inner conductor portion, and the outer terminal is connected to the outer conductor portion in a state where the terminal side extension portion is arranged so as to close the notch, and the connection portion between the connection portion of the inner terminal and the inner conductor portion is covered by the outer conductor portion and the terminal side extension portion.

[0017] In the connector set according to the sixth aspect, in a state where the first connector is connected to the second connector, the connection portion of the inner terminal is connected to the inner conductor portion, and the outer terminal is connected to the outer conductor portion in a state where the terminal side extension portion is arranged so as to close the notch. Further, the connection portion between the connection portion of the inner terminal and the inner conductor portion is covered by the outer conductor portion and the terminal side extension portion. In this configuration, in order to cover the connection portion between the connection portion of the inner terminal and the inner conductor portion, it is not necessary to overlap the outer conductor portion and the outer terminal in a direction (connection axis crossing direction) crossing the connection direction between the inner conductor portion and the inner terminal. Thereby, the size reduction of the connector set in the connection axis crossing direction can be achieved.

[0018] In the connector set according to the seventh aspect, in the connector set according to the sixth aspect, the terminal-side extension portion includes a substrate portion disposed along a portion exposed at the notch in the conductor portion-side dielectric, and a contact portion disposed along the edge of the notch, and the contact portion contacts the edge of the notch in a state of being biased toward the edge side of the notch.

[0019] In the connector set according to the seventh aspect, the portion exposed at the notch in the conductor portion-side dielectric can be covered by the substrate portion of the terminal-side extension portion. Further, by the contact portion of the terminal-side extension portion contacting the edge of the notch in a state of being biased toward the edge side of the notch, a stable conduction state between the outer terminal and the outer conductor portion can be ensured.

Here, as shown in FIGS. 6 and 7, the configurations of the terminal unit 20 and the terminal unit 22 are the same except that the number of inner terminals 26 is different. Therefore, hereinafter, the configuration of the terminal unit 20 will be described, and the description of the configuration of the terminal unit 22 will be omitted. In addition, members and parts corresponding to the terminal unit 20 in the terminal unit 22 will be given the same reference numerals as the members and parts corresponding to the terminal unit 20.

[0030] As shown in FIGS. 6, 8, and 9, the terminal unit 20 includes two inner terminals 26 and an outer terminal 28 that covers the two inner terminals 26. The terminal unit 20 also includes a terminal body 30 and two support members 32.

[0031] One of the inner terminals 26 is formed by bending a member formed in a rod shape using a conductive metal material into a predetermined shape. This inner terminal 26 includes a fitting-side extension portion 26A that constitutes one end of the inner terminal 26, a substrate-side extension portion 26B that constitutes the other end of the inner terminal 26, and an intermediate extension portion 26C that connects the fitting-side extension portion 26A and the substrate-side extension portion 26B.

In other words, the substrate portion 34D of the terminal-side extension portion 34B of the first terminal forming plate 34 extends along the connection portion 26D of the one inner terminal 26 and the connection portion 26D of the other inner terminal 26.

[0041] As shown in FIGS. 8 and 9, the terminal body 30 is formed in a rectangular box shape using a resin material. In this terminal body 30, an inner terminal arrangement recess 30A is formed on the other side in the width direction, which is open, and two inner terminals 26 and two support members 32 are respectively arranged. The bottom part of this inner terminal arrangement recess 30A serves as a support wall part 30B that supports the inner terminal 26.

Also, as shown in FIG. 9, the terminal body 30 includes three fitting parts 30E which are protruding parts protruding toward one side in the width direction. Then, by fitting the fitting part 30E of the terminal body 30 of one terminal unit 20 adjacent in the width direction with the fitting part 30D of the terminal body 30 of the other terminal unit 20, relative displacement in the connection axis direction and the vertical direction of one terminal unit 20 with respect to the other terminal unit 20 is restricted. Note that an opening through which the three fitting parts 30E are inserted is formed in the first main board part 34A of the first terminal forming plate 34.

The two support members 32 are each arranged in a space surrounded by the second main board portion 36A and the second side board portion 36B in the two second terminal forming plates 36. On one side in the width direction of the two support members 32, a support groove 32A into which the inner terminal 26 is fitted is formed.

[0045] And, as shown in FIG. 6, in a state where the terminal unit 20 is assembled, most of the inner terminal 26 is supported by the support wall portion 30B of the terminal body 30 and the support member 32 in a state of being disposed within the terminal-side covering portion 38 of the outer terminal 28. Here, the support wall portion 30B of the terminal body 30 and the support member 32 constitute a terminal unit-side dielectric 40 as a terminal-side dielectric disposed between the inner terminal 26 and the outer terminal 28.

[0046] As shown in FIG. 12, the connecting member 24 is formed using a metal plate. The connecting member 24 is formed in a rectangular shape extending in the width direction and the vertical direction with the connecting axis direction as the thickness direction. A plurality of locking grooves 24A into which the connecting member locking portion 30H of the terminal body 30 is fitted are formed in the lower portion of the connecting member 24. The plurality of locking grooves 24A are arranged at intervals in the width direction. Also, the number of the locking grooves 24A matches the number of the terminal units 20 and 22.

Further, both end portions in the width direction of the connecting member 24 are housing locking portions 24B that are locked to the locking grooves 18E formed in the separation restricting portion 18D of the terminal unit housing 18.

[0047] As shown in FIGS. 2, 3, 4, 5, 6, 7, 8, 9, and 12, the substrate connector 12 of the present embodiment is assembled in the following procedure.

[0048] First, arrange a plurality of terminal units 20 and 22 side by side in the width direction in a state where adjacent ones are in contact with each other. At this time, fit the fitting portion 30E of the terminal body 30 of the terminal units 20 and 22 into the fitted portion 30D of the terminal body 30 of the other adjacent terminal units 20 and 22. In this embodiment, a spacer 41 is provided on one side in the width direction. The fitting portion 30E of the terminal body 30 of the terminal unit 20 arranged at one end on the width direction side is fitted to the spacer 41.

[0049] Next, assemble the plurality of terminal units 20 and 22 arranged in the width direction into the terminal unit housing 18. That is, by moving the plurality of terminal units 20 and 22 arranged in the width direction to the other side in the connection direction, insert the plurality of terminal units 20 and 22 arranged in the width direction into the terminal unit housing 18. At this time, arrange the upper locking protrusion 30F of the terminal body 30 of each terminal unit 20 and 22 in the upper locking groove 18K formed in the terminal unit housing 18, and arrange the lower locking protrusion 30G of the terminal body 30 of each terminal unit 20 and 22 in the lower locking groove 18N formed in the terminal unit housing 18. Then, the upper locking protrusion 30F of the terminal body 30 of each terminal unit 20 and 22 gets over the upper locking portion 18G of the terminal unit housing 18 and is locked to the upper locking portion 18G. Also, the lower locking protrusion 30G of the terminal body 30 of each terminal unit 20 and 22 gets over the lower locking portion 18L of the terminal unit housing 18 and is locked to the lower locking portion 18L. Thereby, the terminal units 20 and 22 are in a state of being assembled to the terminal unit housing 18.

[0050] Next, lock the housing locking portion 24B of the connecting member 24 to the locking groove 18E formed in the separation restricting portion 18D of the terminal unit housing 18, and lock the connecting member locking portion 30H of the terminal body 30 of each terminal unit 20 and 22 to each locking groove 24A of the connecting member 24.

[0051] Through the above steps, the board connector 12 is assembled.

[0052] (Configuration of the wire connector 16) As shown in FIG. 13, the wire connector 16 includes a conductor unit housing 42 and two types of conductor units 44 and 46 supported by the conductor unit housing 42.

[0053] As shown in FIGS. 14 and 15, the conductor unit housing 42 includes a conductor unit housing body 48 formed in a rectangular block shape and a retaining member 50 locked to the conductor unit housing body 48.

[0054] A plurality of conductor unit accommodating portions 48A for accommodating a plurality of conductor units 44 and 46, which will be described later, are formed in the conductor unit housing body 48. The plurality of conductor unit accommodating portions 48A are formed so as to penetrate the conductor unit housing body 48 in the connection axis direction. In this embodiment, the number of the plurality of conductor unit accommodating portions 48A coincides with the number of the plurality of conductor units 44 and 46, which will be described later. That is, 28 conductor unit accommodating portions 48A are formed in the conductor unit housing body 48. More specifically, 14 conductor unit accommodating portions 48A are formed in the upper part of the conductor unit housing body 48, and 14 conductor unit accommodating portions 48A are formed in the lower part of the conductor unit housing body 48.

[0055] Here, the shape and dimensions inside each conductor unit accommodating portion 48A are such that the conductor units 44 and 46, which will be described later, can be inserted from the other side in the connection axis direction. Also, the shape and dimensions inside each conductor unit accommodating portion 48A are set to be such that the conductor units 44 and 46 inserted into the conductor unit accommodating portion 48A do not come out from one side in the connection axis direction.

[0056] A second holding portion 48B as a connection holding portion is formed at the central portion in the width direction at the upper part of the conductor unit housing body 48.

[0057] The plug stopper member 50 includes a main body plate 50A whose longitudinal direction is the width direction, a plurality of partition plates 50B that project from the main body plate 50A toward one side in the connection axis direction and are arranged at intervals in the width direction, and a pair of locking plates 50C that project from both end portions in the width direction of the main body plate 50A toward one side in the connection axis direction. As shown in FIG. 13, the pair of locking plates 50C of the plug stopper member 50 are locked to both end portions in the width direction of the conductor unit housing main body 48, so that the plug stopper member 50 is attached to the conductor unit housing main body 48. Further, in a state where the plug stopper member 50 is attached to the conductor unit housing main body 48, the respective conductor units 44 and 46 accommodated in each conductor unit accommodating portion 48A are prevented from coming out from the respective conductor unit accommodating portions 48A toward the other side in the connection axis direction.

[0058] As shown in FIGS. 6, 7, and 13, the 16 conductor units 44 are connected to the aforementioned 8 terminal units 20. Further, the 12 conductor units 46 are connected to the aforementioned 6 terminal units 22. Here, the configurations of the conductor unit 44 and the conductor unit 46 are the same except that the number of inner conductor portions 52 is different. Therefore, hereinafter, the configuration of the conductor unit 44 will be described, and the description of the configuration of the conductor unit 46 will be omitted. Note that members and portions corresponding to the conductor unit 44 in the conductor unit 46 will be denoted by the same reference numerals as the members and portions corresponding to the conductor unit 44.

[0059] As shown in FIGS. 16 and 17, the conductor unit 44 includes an inner conductor portion 52, an outer conductor portion 54 that covers the inner conductor portion 52, and a pair of conductor unit side dielectrics 56 that are provided between the inner conductor portion 52 and the outer conductor portion 54 and support the inner conductor portion 52 as a conductor portion side dielectric.

[0060] As shown in FIG. 17, the inner conductor portion 52 is formed by bending a metal plate into a cylindrical shape or the like. The end portion on the other side in the connection axis direction of the inner conductor portion 52 is fixed to the core wire 14A of the electric wire 14.

[0061] The outer conductor portion 54 is formed by bending a metal plate cut into a predetermined shape or the like. The outer conductor portion 54 includes a conductor portion side covering portion 58 and an external conductor fixing portion 60. The external conductor fixing portion 60 is fixed to the external conductor 14B of the electric wire 14.

[0062] The conductor portion side covering portion 58 includes a rectangular first conductor plate 58A that extends in the connection axis direction and the up and down directions with the width direction as the thickness direction. The conductor portion side covering portion 58 also includes a pair of second conductor plates 58B that bend and extend from the upper and lower ends of the first conductor plate 58A toward one side in the width direction. The pair of second conductor plates 58B are formed in a rectangular shape that extends in the connection axis direction and the width direction with the up and down direction as the thickness direction and extend parallel to each other. Further, the conductor portion side covering portion 58 includes a pair of third conductor plates 58C that extend upward and downward from the ends on one side in the width direction of the pair of second conductor plates 58B, respectively. The pair of third conductor plates 58C are formed in a rectangular shape that extends in the connection axis direction and the up and down directions with the width direction as the thickness direction and extend parallel to the first conductor plate 58A. Also, the ends of the pair of third conductor plates 58C on the side opposite to the pair of second conductor plates 58B are in contact with or close to each other. Thereby, a cylindrical space is formed between the first conductor plate 58A, the pair of second conductor plates 58B, and the pair of third conductor plates 58C, in which most of the inner conductor portion 52 and the pair of dielectric bodies 56 on the conductor unit side are arranged inside. Here, in the present embodiment, the pair of third conductor plates 58C are configured to extend from a range from the central portion in the connection axis direction of the pair of second conductor plates 58B to the end on the other side in the connection axis direction. Thereby, a notch portion 58D in which a part of the conductor portion side covering portion 58 is cut out is formed on one side in the connection axis direction of the conductor portion side covering portion 58.

[0063] A pair of conductor unit side dielectrics 56 are formed in a block shape. On one conductor unit side dielectric 56, on the side of the other conductor unit side dielectric 56, a support groove 56A into which the inner conductor portion 52 fits is formed. Also, on the other conductor unit side dielectric 56, on the side of one conductor unit side dielectric 56, a support groove 56A into which the inner conductor portion 52 fits is formed. Then, as shown in FIGS. 16 and 17, the pair of conductor unit side dielectrics 56 are fitted in the width direction, and the inner conductor portion 52 is arranged between the pair of conductor unit side dielectrics 56, so that the inner conductor portion 52 is supported by the pair of conductor unit side dielectrics 56. Further, the pair of conductor unit side dielectrics 56 are arranged within the conductor portion side covering portion 58 of the outer conductor portion 54. In a state where the pair of conductor unit side dielectrics 56 are arranged within the conductor portion side covering portion 58 of the outer conductor portion 54, a part 56B of the pair of conductor unit side dielectrics 56 is exposed at the notch portion 58D.

[0064] As shown in FIGS. 13 to 15, the wire connector 16 of the present embodiment is assembled in the following procedure.

[0065] First, a plurality of conductor units 44, 46 are respectively inserted into a plurality of conductor unit accommodating portions 48A of the conductor unit housing main body 48. Next, by locking a pair of locking plates 50C of the retaining member 50 to both ends in the width direction of the conductor unit housing main body 48, the retaining member 50 is attached to the conductor unit housing main body 48. Through these steps, the wire connector 16 of the present embodiment in which a plurality of conductor units 44, 46 are arranged in 14 rows in the width direction and 2 rows in the vertical direction is assembled.

[0066] (Operation and Effect of the Present Embodiment) Next, the operation and effect of the present embodiment will be described.

[0067] As shown in FIGS. 1, 2, and 13, the board connector 12 and the wire connector 16 of the present embodiment are connected by inserting a portion on the connection axis direction side in the conductor unit housing main body 48 of the wire connector 16 into the terminal unit housing 18 of the board connector 12.

[0068] Further, in a state where the board connector 12 and the wire connector 16 are connected, the first holding portion 18F of the terminal unit housing 18 and the second holding portion 48B of the conductor unit housing main body 48 are engaged with each other. Thereby, the connection state between the board connector 12 and the wire connector 16 can be easily maintained. Further, in the present embodiment, the connection holding member 62 is engaged with the second holding portion 48B. Thereby, the disengagement of the engagement between the first holding portion 18F and the second holding portion 48B is restricted by the connection holding member 62. Note that the connection between the board connector 12 and the wire connector 16 can be released by removing the connection holding member 62 from the second holding portion 48B and releasing the engagement between the first holding portion 18F and the second holding portion 48B.

[0069] Here, when the board connector 12 and the wire connector 16 are connected, the plurality of terminal units 20, 22 and the plurality of conductor units 44, 46 are simultaneously connected respectively. Thereby, the configuration of the present embodiment can improve workability as compared with a configuration in which the plurality of terminal units 20, 22 and the plurality of conductor units 44, 46 are individually connected. Hereinafter, the connection between one terminal unit 20 and a pair of conductor units 44 will be described.

[0070] Figures 18 to 20 show the terminal unit 20 and the pair of conductor units 44 before connection, and Figures 21 to 23 show the terminal unit 20 and the pair of conductor units 44 after the connection is completed. As shown in these figures, in a state where the terminal unit 20 and the pair of conductor units 44 are connected, the connection portion 26D of one inner terminal 26 of the terminal unit 20 is connected to the inner conductor portion 52 (see Figure 16) of one conductor unit 44, and the connection portion 26D of the other inner terminal 26 of the terminal unit 20 is connected to the inner conductor portion 52 (see Figure 16) of the other conductor unit 44.

[0071] Also, in a state where the terminal unit 20 and the pair of conductor units 44 are connected, the substrate portion 34D of the terminal-side extension portion 34B of the outer terminal 28 of the terminal unit 20 is arranged to close the notch portion 58D of the conductor-side covering portion 58 of the outer conductor portion 54 of one conductor unit 44 and is arranged to close the notch portion 58D of the conductor-side covering portion 58 of the outer conductor portion 54 of the other conductor unit 44.

[0072] Also, in a state where the terminal unit 20 and the pair of conductor units 44 are connected, the pair of contact portions 34E of the terminal-side extension portion 34B of the outer terminal 28 of the terminal unit 20 contact the edge (the ends of the pair of second conductor plates 58B) of the notch portion 58D of the conductor-side covering portion 58 of the outer conductor portion 54 of one conductor unit 44. Further, the other pair of contact portions 34E of the terminal-side extension portion 34B of the outer terminal 28 of the terminal unit 20 contact the edge (the ends of the pair of second conductor plates 58B) of the notch portion 58D of the conductor-side covering portion 58 of the outer conductor portion 54 of the other conductor unit 44. Thereby, the outer terminal 28 of the terminal unit 20 and the outer conductor portions 54 of the pair of conductor units 44 are connected. Here, in the present embodiment, when the outer terminal 28 of the terminal unit 20 and the outer conductor portions 54 of the pair of conductor units 44 are connected, the contact portion 34E bends to the side opposite to the edge of the notch portion 58D. Thereby, the contact portion 34E is in contact with the edge of the notch portion 58D in a state of being biased toward the edge side of the notch portion 58D.

[0073] Here, the board connector 12 of the present embodiment includes a plurality of terminal units 20, 22 having inner terminals 26, outer terminals 28, and a terminal unit side dielectric 40. The plurality of terminal units 20, 22 are arranged side by side in the width direction in a state where adjacent ones are in contact with each other. Thus, in the configuration of the board connector 12 of the present embodiment, by appropriately setting the number of the plurality of terminal units 20, 22, it is possible to easily expand the variations of the board connector 12 corresponding to the variations of the wire connector 16.

[0074] Also, as shown in FIGS. 2, 3, 8, and 9, in the board connector 12 of the present embodiment, the fitting portion 30E of one terminal unit 20, 22 is fitted into the fitted portion 30D of another terminal unit 20, 22 adjacent to the one terminal unit 20, 22. Thereby, the relative displacement of one terminal unit 20, 22 with respect to the other terminal units 20, 22 is restricted. As a result, when arranging the plurality of terminal units 20, 22 in one direction, it is possible to easily position one terminal unit 20, 22 with respect to the other terminal units 20, 22.

[0075] Furthermore, in the board connector 12 of the present embodiment, the direction in which the fitting portion 30E and the fitted portion 30D are fitted is a direction intersecting (orthogonal) to the connection axis direction. Thereby, when connecting the board connector 12 and the wire connector 16, it is possible to suppress the fitting portion 30E of one terminal unit 20, 22 from coming off the fitted portion 30D of the other terminal units 20, 22.

[0076] Also, as shown in FIGS. 6 to 11, in the board connector 12 of the present embodiment, the outer terminals 28 of the terminal units 20, 22 are constituted by a first terminal forming plate 34 and a second terminal forming plate 36. Thereby, the outer terminal 28 having a terminal side covering portion 38 can be formed at low cost. Furthermore, in the board connector 12 of the present embodiment, by combining a single first terminal forming plate 34 and two second terminal forming plates 36, two terminal side covering portions 38 can be formed along the single first terminal forming plate 34.

[0077] Furthermore, in the board connector 12 of the present embodiment, the terminal-side covering portion 38 is formed by at least one of the first main board portion 34A, the second main board portion 36A, the first side board portion 34F, and the second side board portion 36B. With this configuration, the terminal-side covering portion 38 corresponding to the inner terminal 26 having a bent shape as in the present embodiment can be easily formed. In addition, with this configuration, the terminal-side covering portion 38 corresponding to the inner terminal having a curved shape can also be easily formed.

[0078] Also, as shown in FIG. 3, in the board connector 12 of the present embodiment, the plurality of terminal units 20 and 22 are arranged between the pair of separation restricting portions 18D of the terminal unit housing 18, so that the separation of the plurality of terminal units 20 and 22 in the width direction can be restricted by the pair of separation restricting portions 18D.

[0079] Furthermore, in the present embodiment, the connection member locking portions 30H of the terminal bodies 30 of the respective terminal units 20 and 22 are locked to the respective locking grooves 24A of the connection member 24. Thereby, the connection state with the plurality of terminal units 20 and 22 can be easily maintained. In addition to this, the housing locking portion 24B of the connection member 24 is locked to the locking groove 18E formed in the separation restricting portion 18D of the terminal unit housing 18. Thereby, the plurality of terminal units 20 and 22 and the terminal unit housing 18 can be firmly integrated.

[0080] Also, as shown in FIGS. 13 to 16, the wire connector 16 of the present embodiment includes a conductor unit housing 42 having a plurality of conductor unit accommodating portions 48A. Thereby, by accommodating the plurality of conductor units 44 and 46 in the plurality of conductor unit accommodating portions 48A respectively, the plurality of conductor units 44 and 46 can be easily supported at predetermined positions of the conductor unit housing 42.

[0081] Furthermore, as shown in FIGS. 18 to 23, in the present embodiment, with the substrate connector 12 connected to the wire connector 16, the connection portion 26D of the inner terminal 26 is connected to the inner conductor portion 52, and the outer terminal 28 is connected to the outer conductor portion 54 in a state where the terminal-side extension portion 34B is arranged so as to close the notch portion 58D. Further, the connection portion between the connection portion 26D of the inner terminal 26 and the inner conductor portion 52 is covered by the outer conductor portion 54 and the terminal-side extension portion 34B. In this configuration, in order to cover the connection portion between the connection portion 26D of the inner terminal 26 and the inner conductor portion 52, it is not necessary to arrange the outer conductor portion 54 and the outer terminal 28 overlappingly in a direction (connection axis crossing direction) crossing the connection axis direction. Thereby, the size reduction of the connector set 10 in the connection axis crossing direction can be achieved.

[0082] In the present embodiment, the contact portion 34E of the terminal-side extension portion 34B of the outer terminal 28 is in contact with the edge of the notch portion 58D in a state of being biased toward the edge of the notch portion 58D of the outer conductor portion 54 (conductor portion side covering portion 58). Thereby, a stable conduction state between the outer terminal 28 and the outer conductor portion 54 can be ensured.

[0083] In the present embodiment, the inner terminal 26 is covered by the terminal-side covering portion 38 of the outer terminal 28, and the inner conductor portion 52 is covered by the conductor portion side covering portion 58 of the outer conductor portion 54. Thereby, electromagnetic noise resistance performance can be ensured. In the present embodiment, in addition to the terminal unit side dielectric 40 that supports the inner terminal 26 being provided inside the terminal-side covering portion 38 of the outer terminal 28, the conductor unit side dielectric 56 that supports the inner conductor portion 52 is provided inside the conductor portion side covering portion 58 of the outer conductor portion 54. In this configuration, impedance matching can be facilitated by adjusting the volumes of the terminal unit side dielectric 40 and the conductor unit side dielectric 56.

[0084] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above, and it goes without saying that various modifications other than the above can be made without departing from the gist of the present invention.
