Description

[Technical Field]

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

[0002] Patent Document 1 discloses a connector equipped with two types of terminal units with different functions. This connector includes a plurality of terminal units made up of the two types of terminal units and a base housing. The base housing has a plurality of housing portions in which the plurality of terminal units are housed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-28570 Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure aims to provide a connector and a group of connector components that can easily be made more versatile. [Means for solving the problem]

[0005] The connector of the first aspect is a connector comprising a plurality of terminal units and a base housing having a plurality of accommodating portions in which the plurality of terminal units are accommodated, wherein the plurality of terminal units include a first terminal unit and a second terminal unit having different functions from each other, and the plurality of accommodating portions include a shared accommodating portion that can accommodate either the first terminal unit or the second terminal unit.

[0006] In this aspect, the connector includes a plurality of terminal units and a base housing having a plurality of accommodating portions for accommodating the plurality of terminal units. The plurality of terminal units include a first terminal unit and a second terminal unit having mutually different functions. This makes it possible to realize a connector that includes a first terminal unit and a second terminal unit that have different functions.

[0007] Incidentally, it is conceivable that the housing portion for housing a first terminal unit among the plurality of housing portions is a housing portion dedicated to the first terminal unit, and the housing portion for housing a second terminal unit among the plurality of housing portions is a housing portion dedicated to the second terminal unit (see Patent Document 1). However, in such a configuration, in order to manufacture a connector with a different arrangement of the first terminal unit and the second terminal unit, it is necessary to prepare a new base housing with a different structure. This hinders increasing the variety of connectors. Therefore, in this aspect, the plurality of accommodating portions include an accommodating portion (shared accommodating portion) that can accommodate both the first terminal unit and the second terminal unit. Therefore, connectors with different terminal unit arrangements can be manufactured using base housings of the same structure, making it easy to increase the variety of connectors.

[0008] In the embodiment described below, the first terminal unit is a coaxial terminal unit, and the second terminal unit is a differential transmission terminal unit. However, this embodiment is not limited to this. Specific examples of the first terminal unit or the second terminal unit include, in addition to the above, a signal terminal unit (low-speed terminal unit), an optical terminal unit, a power terminal unit, etc. In the embodiment described below, the plurality of terminal units does not include terminal units other than the first terminal unit and the second terminal unit, but the plurality of terminal units in this embodiment is not limited to this and may include a third terminal unit, a fourth terminal unit, etc. In the embodiment described below, the multiple terminal units are composed of multiple types (two types) of terminal units with different functions, and the multiple accommodating sections include a shared accommodating section that can accommodate any of the multiple types (two types) of terminal units. In other words, the shared accommodating section is a accommodating section that can accommodate any of all types of terminal units provided in the connector. However, the shared accommodating section in this embodiment is not limited to this. For example, the shared accommodating section may be unable to accommodate one or more types of terminal units out of three or more types of terminal units provided in the connector. In the embodiment described below, each of the plurality of storage sections is a shared storage section. However, this aspect is not limited to this. The plurality of storage sections may include a storage section that is not a shared storage section. In the embodiment described below, the connector includes a restricting member, but the connector of this aspect is not limited to this. In the embodiment described below, the connector is a right-angle connector, but the present embodiment is not limited to this. In the embodiment described below, one terminal unit is configured to be connectable to two mating terminal units, but the terminal unit of this embodiment is not limited to this. In the embodiment described below, the base housing includes at least one partition wall disposed between two adjacent storage sections among the plurality of storage sections. However, this embodiment is not limited to this, and there does not need to be a partition wall between two adjacent storage sections among the plurality of storage sections.

[0009] The connector according to a second aspect is the connector of the first aspect, wherein each of the plurality of accommodating portions is a shared accommodating portion capable of accommodating either the first terminal unit or the second terminal unit.

[0010] In this aspect, each of the plurality of accommodating portions is a common accommodating portion that can accommodate either the first terminal unit or the second terminal unit. This makes it easier to further increase the variety of connectors.

[0011] A third aspect of the connector is a right-angle type connector that is attached to a mounting surface of a circuit board in the first or second aspect, and when the normal direction to the mounting surface is defined as the upward direction, the direction parallel to the mounting surface in which a mating connector is arranged relative to the connector is defined as the forward direction, and the direction perpendicular to both the upward and forward directions is defined as the width direction, the base housing comprises a pair of side walls spaced apart in the width direction, between which the multiple accommodating sections are formed, a top wall connecting the upper ends of the pair of side walls, and a bottom wall connecting the lower ends of the pair of side walls, and each of the multiple accommodating sections is open downward.

[0012] In this aspect, the connector is a right-angle connector that is attached to the mounting surface of a circuit board. The base housing includes a pair of side walls spaced apart in the width direction, a top wall connecting the upper ends of the pair of side walls, and a bottom wall connecting the lower ends of the pair of side walls. The multiple storage compartments are formed between the pair of side walls.

[0013] In this aspect, each of the plurality of storage sections is open downward. Therefore, the open portion can be used to connect the terminal unit to the circuit board.

[0014] A fourth aspect of the connector is the third aspect, wherein the base housing has at least one partition wall arranged between two adjacent accommodating sections among the plurality of accommodating sections, and the partition wall connects the top wall and the bottom wall.

[0015] However, if the distance between the pair of side walls is large, the base housing may be warped and deformed. Therefore, in this aspect, the base housing includes at least one partition wall that is disposed between two adjacent storage sections among the plurality of storage sections and connects the top wall and the bottom wall. Therefore, at least one partition wall can suppress warping of the base housing.

[0016] In the embodiment described below, the rear surface of the partition wall and the rear surface of the top wall are flush with each other, but the present embodiment is not limited to this. In the embodiment described below, the lower surface of the partition wall and the lower surface of the bottom wall are flush with each other, but the present embodiment is not limited to this.

[0017] The connector of the fifth aspect is any one of the first to fourth aspects, wherein the first terminal unit comprises an inner terminal portion consisting of at least one inner terminal, an outer terminal portion surrounding the inner terminal portion, and a dielectric portion holding the inner terminal portion and the outer terminal portion.

[0018] In this aspect, the first terminal unit includes an inner terminal portion formed of at least one inner terminal, an outer terminal portion surrounding the inner terminal portion, and a dielectric portion holding the inner terminal portion and the outer terminal portion. Therefore, compared to a configuration in which the first terminal unit does not have outer terminal portions, the connector can be made more suitable for high-speed transmission.

[0019] In the embodiment described below, the second terminal unit also includes an inner terminal portion, an outer terminal portion, and a dielectric portion, but the second terminal unit of this aspect is not limited to this.

[0020] The connector of the sixth aspect is the connector of the fifth aspect, wherein the dielectric portion is molded by insert molding using the inner terminal portion as an insert component, and the dielectric portion has an intervening portion interposed between the inner terminal portion and the outer terminal portion.

[0021] In this aspect, the dielectric portion is molded by insert molding using the inner terminal portion as an insert component, and has an interposition portion interposed between the inner terminal portion and the outer terminal portion. Therefore, the dielectric portion having the interposed portion can be integrally formed.

[0022] The connector of the seventh aspect is any of the first to fourth aspects, wherein the first terminal unit comprises a first inner terminal portion consisting of at least one first inner terminal, a second inner terminal portion consisting of at least one second inner terminal, an outer terminal portion separately surrounding the first inner terminal portion and the second inner terminal portion, and a dielectric portion holding the first inner terminal portion, the second inner terminal portion, and the outer terminal portion.

[0023] In this aspect, the first terminal unit includes a first inner terminal portion, a second inner terminal portion, an outer terminal portion that separately surrounds the first inner terminal portion and the second inner terminal portion, and a dielectric portion that holds the first inner terminal portion, the second inner terminal portion, and the outer terminal portion. Therefore, the number of terminal units can be reduced compared to an embodiment in which the first terminal unit does not include the second inner terminal portion.

[0024] In the embodiment described below, the second terminal unit also includes a first inner terminal portion, a second inner terminal portion, an outer terminal portion, and a dielectric portion, but the second terminal unit of this aspect is not limited to this.

[0025] The connector of the eighth aspect is the connector of the seventh aspect, wherein the dielectric portion is molded by insert molding using the first inner terminal portion and the second inner terminal portion as insert components, and the dielectric portion has a first intervening portion interposed between the first inner terminal portion and the outer terminal portion, and a second intervening portion interposed between the second inner terminal portion and the outer terminal portion.

[0026] In this aspect, the dielectric portion is molded by insert molding using the first inner terminal portion and the second inner terminal portion as insert components. The dielectric portion has a first intermediate portion interposed between the first inner terminal portion and the outer terminal portion, and a second intermediate portion interposed between the second inner terminal portion and the outer terminal portion. Therefore, the dielectric portion having the first intermediate portion and the second intermediate portion can be integrally formed.

[0027] A connector component group according to a ninth aspect is a connector component group for manufacturing a connector, and comprises a plurality of types of terminal units including a first terminal unit and a second terminal unit having different functions, and a base housing having at least one accommodating section for accommodating the terminal units, wherein the at least one accommodating section includes a shared accommodating section capable of accommodating either the first terminal unit or the second terminal unit.

[0028] In this aspect, the connector component group includes a plurality of terminal units and a base housing having at least one receiving portion for receiving the terminal units. The plurality of terminal units include a first terminal unit and a second terminal unit having different functions from each other.

[0029] Furthermore, in this aspect, at least one of the accommodating portions includes an accommodating portion (shared accommodating portion) that can accommodate both the first terminal unit and the second terminal unit. Therefore, connectors with different terminal unit arrangements can be manufactured using base housings of the same structure, making it easy to increase the variety of connectors.

[0030] In the embodiment described below, the base housing has a plurality of accommodating portions, but the base housing of this embodiment is not limited to this and may have only one accommodating portion. In the embodiment described below, the connector has a plurality of terminal units, and the plurality of terminal units includes a first terminal unit and a second terminal unit. However, the connector manufactured from the connector component group of this aspect is not limited to this. For example, the plurality of terminal units of the connector may all be first terminal units. [Brief explanation of the drawings]

[0032] A board connector 10 according to an embodiment of the connector of the present disclosure will be described below.

[0033] In the following description, the arrow X direction shown in each drawing indicates one side of the connector width direction, the arrow Y direction indicates the connector forward direction, and the arrow Z direction indicates the connector upward direction. However, these terms do not limit the connector's position when in use. Hereinafter, when simply referring to the width direction, forward direction, or upward direction, it means the connector width direction, connector forward direction, or connector upward direction.

[0034] 9 and 10, the board connector 10 is attached to a mounting surface 92 of a circuit board 90, which serves as an "attachment object." The board connector 10 is configured to be connectable to a cable connector 200 (see FIG. 2), which serves as a "mating connector." The connection direction in which the board connector 10 and the cable connector 200 are connected is the front-to-rear direction.

[0035] As shown in FIG. 3, the board connector 10 includes a base housing 20, a plurality of terminal units 30A, 30B housed in the base housing 20, a restricting member 40, and two reinforcing members 50.

[0036] (Base housing 20) The base housing 20 includes a pair of side walls 21, a top wall 22, a bottom wall 23 (see FIG. 1), and a plurality of (five) partition walls 24.

[0037] The pair of side walls 21 are walls whose thickness direction is oriented in the width direction and are provided with a gap in the width direction. The top wall 22 connects the upper ends of the pair of side walls 21 in the width direction. The bottom wall 23 connects the lower ends of the pair of side walls 21 in the width direction.

[0038] A plurality of accommodating sections 25 (see FIG. 3) for accommodating a plurality of terminal units 30A, 30B are formed in a portion of the space between the pair of side walls 21 that corresponds to the connector rear section 10R (see FIGS. 9 and 10). Each of the plurality of partition walls 24 is provided between two adjacent accommodating sections 25 of the plurality of accommodating sections 25. The structures (e.g., width dimensions) of the accommodating sections 25 are identical to one another.

[0039] 9 and 10, the rear end of the bottom wall 23 is located forward of the rear ends of the side walls 21 and the top wall 22. Therefore, the bottom wall 23 does not exist in most of the connector rear portion 10R. Therefore, the accommodating portion 25 is open downward. This open portion is used to electrically connect the inner terminals 61 and outer terminals 71, 72 of the terminal units 30A, 30B to the circuit board 90.

[0040] 9 and 10 , the portion of the space between the pair of side walls 21 corresponding to the connector front portion 10F serves as an insertion space 26 into which a portion of the mating connector 200 is inserted. Front portions of the inner terminals 61 and outer terminals 71, 72 included in the terminal units 30A, 30B are disposed within the insertion space 26.

[0041] As shown in FIG. 8, the top wall 22 has an upper engagement groove 22a. An upper engagement groove 22a is provided for each accommodation portion 25. The multiple upper engagement grooves 22a have the same structure. The upper engagement grooves 22a are grooves formed on the underside of the top wall 22 and extend in the front-rear direction. The upper engagement grooves 22a accommodate portions of the terminal units 30A, 30B (upper engagement portions 81, see FIGS. 4 and 6). As a result, the upper engagement grooves 22a have the function of positioning the terminal units 30A, 30B in the width direction relative to the base housing 20. The upper engagement grooves 22a are provided in a portion of the top wall 22 corresponding to the connector rear portion 10R.

[0042] As shown in FIG. 8, the bottom wall 23 has a lower engagement groove 23a. A lower engagement groove 23a is provided for each accommodation portion 25. The multiple lower engagement grooves 23a have the same structure. The lower engagement grooves 23a are grooves formed on the upper surface of the bottom wall 23 and extend in the front-rear direction. The lower engagement grooves 23a accommodate portions of the terminal units 30A, 30B (lower engagement portions 82, see FIGS. 4 and 6). As a result, the lower engagement grooves 23a have the function of positioning the terminal units 30A, 30B in the width direction relative to the base housing 20. The lower engagement grooves 23a are provided in a portion of the bottom wall 23 corresponding to the connector rear portion 10R.

[0043] As shown in Figures 2 and 3, the base housing 20 has restriction member holding portions 27, 27 that hold the restriction member 40. The restriction member holding portions 27, 27 are composed of a pair of protrusions 27. Each of the pair of protrusions 27 protrudes rearward from each of the pair of side walls 21. The upper ends of the protrusions 27 are located below the upper surface of the top wall 22. A press-fit groove is formed on the inner surface of each protrusion 27 in the width direction, into which a portion (lower part) of the restriction member 40 is press-fitted.

[0044] As shown in Figures 2 and 3, the base housing 20 has two reinforcing member holding portions 28 that hold two reinforcing members 50. The reinforcing member holding portions 28 protrude outward in the width direction from the side walls 21. The reinforcing members 50 are press-fitted into the reinforcing member holding portions 28 from above. The upper ends of the protruding portions 27 are located below the upper surface of the top wall 22 and also below the upper ends of the protruding portions 27. The reinforcing members 50 are held in positions corresponding to the connector front portion 10F.

[0045] (Terminal units 30A, 30B) 3, the multiple terminal units 30A, 30B are configured from multiple first terminal units 30A and multiple second terminal units 30B. The multiple first terminal units 30A are provided on one widthwise side, and the multiple second terminal units 30B are provided on the other widthwise side. The first terminal units 30A are coaxial terminal units, and the second terminal units 30B are differential transmission terminal units.

[0046] 2, the cable connector 200 includes a mating base housing 220 and a plurality of mating terminal units 230A, 230B housed in the mating base housing 220. The cable connector 200 is attached to a plurality of cables 290. Specifically, each of the plurality of mating terminal units 230A, 230B is attached to the cable 290. One first terminal unit 30A can be connected to two mating first terminal units 230A, and one second terminal unit 30B can be connected to two mating second terminal units 230B.

[0047] The first terminal unit 30A and the second terminal unit 30B have much in common, and therefore the same reference numerals will be used to designate corresponding members and portions of the first terminal unit 30A and the second terminal unit 30B.

[0048] Hereinafter, when describing the configuration common to the first terminal unit 30A and the second terminal unit 30B, they will simply be referred to as terminal unit 30.

[0049] 4 to 7, the terminal unit 30 includes two inner terminal portions 60K, 60L, outer terminal portions 71, 72K, 72L, and a dielectric portion 80. The two inner terminal portions 60K, 60L are each composed of a first inner terminal portion 60K and a second inner terminal portion 60L.

[0050] Hereinafter, when describing the configuration common to the first inner terminal portion 60K and the second inner terminal portion 60L, they will be simply referred to as the inner terminal portion 60.

[0051] As shown in FIGS. 4 and 5, the inner terminal portion 60 of the first terminal unit 30A is composed of a first inner terminal 61A. As shown in FIGS. 6 and 7, the inner terminal portion 60 of the second terminal unit 30B is composed of a second inner terminal 61B and a third inner terminal 61C.

[0052] Hereinafter, when describing the configuration common to the first inner terminal 61A, the second inner terminal 61B, and the third inner terminal 61C, they will be simply referred to as the inner terminal 61.

[0053] 9 and 10, each of the inner terminals 61 included in one terminal unit 30 extends within the same cross section (cross section perpendicular to the width direction). Each inner terminal 61 includes a contact portion 61a that contacts a terminal of the cable connector 200, a connection portion 61b that is connected to the circuit board 90, and a connection portion 61c that connects the contact portion 61a and the connection portion 61b together.

[0054] As shown in Figures 9 and 10, the contact portion 61a is exposed from the dielectric portion 80 and extends in the front-to-rear direction. The connection portion 61b is exposed from the dielectric portion 80 and extends in the up-down direction. The linking portion 61c is held in a buried state in the dielectric portion 80. The linking portion 61c has an inclined portion 61d that extends in a direction inclined downward toward the rear.

[0055] Next, the second inner terminal 61B and the third inner terminal 61C that constitute the inner terminal portion 60 of the second terminal unit 30B will be described with reference to FIG.

[0056] 10, the contact portion 61a of the second inner terminal 61B and the contact portion 61a of the third inner terminal 61C extend parallel to each other. Furthermore, the connection portion 61b of the second inner terminal 61B and the connection portion 61b of the third inner terminal 61C extend parallel to each other. Furthermore, the inclined portion 61d of the second inner terminal 61B and the inclined portion 61d of the third inner terminal 61C extend parallel to each other.

[0057] 10, the distance between the inclined portion 61d of the second inner terminal 61B and the inclined portion 61d of the third inner terminal 61C is narrower than the distance between the contact portion 61a of the second inner terminal 61B and the contact portion 61a of the third inner terminal 61C, and is narrower than the distance between the connection portion 61b of the second inner terminal 61B and the connection portion 61b of the third inner terminal 61C. This makes the electrical length of the third inner terminal 61C closer to the electrical length of the second inner terminal 61B.

[0058] As shown in FIGS. 4 to 7, the outer terminal portions 71, 72K, 72L are configured to surround the first inner terminal portion 60K and the second inner terminal portion 60L, respectively.

[0059] Specifically, the outer terminal portions 71, 72K, 72L are composed of a first outer terminal 71 and two second outer terminals 72K, 72L. The first outer terminal 71 and the two second outer terminals 72K, 72L are both formed from metal plates. The two second outer terminals 72K, 72L are arranged on the other widthwise side of the first outer terminal 71. One inner terminal portion 60K of the two inner terminal portions 60K, 60L is surrounded by the first outer terminal 71 and one second outer terminal 72K. The other inner terminal portion 60L of the two inner terminal portions 60K, 60L is surrounded by the first outer terminal 71 and the other second outer terminal 72L.

[0060] Hereinafter, when describing the configuration common to one second outer terminal 72K and the other second outer terminal 72L, they will simply be referred to as the second outer terminal 72.

[0061] As shown in Figures 5 and 7, the first outer terminal 71 has a first main plate portion 71a whose thickness direction is oriented in the width direction, and a plurality of connection piece portions 71c that protrude from the first main plate portion 71a and are connected to the circuit board 90.

[0062] As shown in Figures 5 and 7, the second outer terminal 72 includes a second main plate portion 72a whose thickness direction is oriented in the width direction, a pair of side plate portions 72b extending from the end of the second main plate portion 72a toward the first main plate portion 71a of the first outer terminal 71, and a plurality of connecting piece portions 72c protruding from the second main plate portion 72a and connected to the circuit board 90.

[0063] The dielectric portion 80 is made of a resin material. Specifically, the dielectric portion 80 is molded by insert molding, in which the inner terminals 61 constituting the two inner terminal portions 60K, 60L are inserted. The first outer terminal 71 and the two second outer terminals 72K, 72L constituting the outer terminal portions 71, 72K, 72L are later assembled to the insert-molded products 60, 80.

[0064] As shown in Figures 4 and 6, the dielectric part 80 has an upper engagement part 81. The upper engagement part 81 is a part that engages with the upper engagement groove 22a of the base housing 20. The upper engagement part 81 is a convex part that protrudes upward from the top surface 80a of the dielectric part 80 and extends in the front-to-rear direction. The upper engagement part 81 has a front part 81f with a small width dimension and a rear part 82r with a small width dimension.

[0065] As shown in Figures 4 and 6, the dielectric part 80 has a lower engagement part 82. The lower engagement part 82 is a part that engages with the lower engagement groove 23a of the base housing 20. The lower engagement part 82 is a convex part that protrudes downward. The lower engagement part 82 is provided at the front end part of the dielectric part 80.

[0066] As shown in FIGS. 4 and 6, the dielectric portion 80 has a rear engagement portion 83. The rear engagement portion 83 protrudes rearward from the rear surface of the dielectric portion 80. As shown in FIG. 2, the rear engagement portion 83 is a portion that is press-fitted into the recess 42 (see FIG. 3) of the restricting member 40. The rear engagement portion 83 is provided at the lower end of the dielectric portion 80.

[0067] The first terminal unit 30A and the second terminal unit 30B have the same arrangement and structure of the upper engaging portion 81, the lower engaging portion 82, and the rear engaging portion 83. This makes the first terminal unit 30A and the second terminal unit 30B compatible with each other in terms of accommodation in the accommodation portion 25.

[0068] (Regulating member 40) 2 and 3, the restricting member 40 is press-fitted between a pair of protruding portions 27 of the restricting member holding portions 27, 27 of the base housing 20. The restricting member 40 has a pair of outer protrusions 41. This allows the restricting member 40 to be held by the base housing 20.

[0069] The restricting member 40 has recesses 42. The recesses 42 are provided corresponding to the terminal units 30A, 30B. The rear engagement portions 83 of the terminal units 30A, 30B are press-fitted into the recesses 42. The recesses 42 are provided in the lower part of the restricting member 40 and open downward.

[0070] Explaining this differently, as shown in FIG. 3, the regulating member 40 includes a main body 40a and a plurality of extending portions 40b extending downward from the main body 40a. Each extending portion 40b has a protrusion on both sides in the width direction. The recess formed between two adjacent extending portions 40b among the plurality of extending portions 40b is the recess 42 described above. Furthermore, one of a pair of protrusions provided on the extending portion 40b that is outermost in the width direction among the plurality of extending portions 40b is the outer protrusion 41 described above. The regulating member 40 is formed, for example, from a metal plate. The regulating member 40 does not have any bent portions in the plate material.

[0071] (reinforcing member 50) The reinforcing member 50 is held by the reinforcing member holding portion 28 of the base housing 20 and is fixed to the circuit board 90 by soldering. As a result, the reinforcing member 50 has the function of reinforcing the attachment strength of the connector 10 to the circuit board 90.

[0072] The board connector 10 of this embodiment is assembled in the following procedure.

[0073] First, the plurality of terminal units 30A, 30B are assembled to the base housing 20. That is, the plurality of terminal units 30A, 30B are inserted into the plurality of accommodating portions 25 of the base housing 20 from the rear side of the base housing 20.

[0074] Next, the restricting member 40 is held by the restricting member holding portions 27, 27 of the base housing 20, and the rear engaging portions 83 of the dielectric portions 80 of the terminal units 30A, 30B are press-fitted into the recesses 42 of the restricting member 40.

[0075] Through the above steps, the board connector 10 is assembled.

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

[0077] 3, the connector 10 includes a plurality of terminal units 30A, 30B and a base housing 20 having a plurality of accommodating portions 25 for accommodating the plurality of terminal units 30A, 30B. The plurality of terminal units 30A, 30B include a first terminal unit 30A (see FIGS. 5 and 6) and a second terminal unit 30B (see FIGS. 7 and 8) that have different functions. Therefore, it is possible to realize a connector 10 including a first terminal unit 30A and a second terminal unit 30B that have different functions.

[0078] Incidentally, it is conceivable that the accommodating portion 25 for accommodating the first terminal unit 30A among the plurality of accommodating portions 25 is a dedicated accommodating portion for the first terminal unit 30A, and the accommodating portion 25 for accommodating the second terminal unit 30B among the plurality of accommodating portions 25 is a dedicated accommodating portion for the second terminal unit 30B (see Patent Document 1). However, in such an embodiment, in order to manufacture a connector with a different arrangement of the first terminal unit 30A and the second terminal unit 30B, it is necessary to prepare a new base housing with a different structure. This hinders increasing the variety of connectors. Therefore, in this embodiment, as shown in Figures 3 and 9, the multiple accommodating sections 25 include an accommodating section 25 (shared accommodating section 25) that can accommodate either the first terminal unit 30A or the second terminal unit 30B. Therefore, it is possible to manufacture connectors 10 having different arrangements of the terminal units 30A, 30B using the same structure of the base housing 20. This makes it easy to increase the variety of connectors 10.

[0079] In this embodiment, each of the plurality of accommodating portions 25 is a shared accommodating portion 25 that can accommodate either the first terminal unit 30A or the second terminal unit 30B. This makes it easier to further increase the variety of connectors 10.

[0080] 10 and 11, the connector 10 in this embodiment is a right-angle type connector that is attached to a mounting surface 92 of a circuit board 90. As shown in Fig. 3, the base housing 20 includes a pair of side walls 21 spaced apart in the width direction, a top wall 22 connecting the upper ends of the pair of side walls 21, and a bottom wall 23 connecting the lower ends of the pair of side walls 21 (see Figs. 9, 10, and 11). A plurality of accommodating portions 25 are formed between the pair of side walls 21. Here, each of the plurality of storage sections 25 is open downward. Therefore, as shown in FIGS. 10 and 11, the terminal units 30A and 30B can be connected to the circuit board 90 by utilizing the open portions.

[0081] However, if the distance between the pair of side walls 21 is large, the base housing 20 may be warped and deformed. Therefore, in this embodiment, the base housing 20 includes at least one partition wall 24. As shown in Fig. 9, the partition wall 24 is disposed between two adjacent storage sections 25 among the plurality of storage sections 25, and connects the top wall 22 and the bottom wall 23. Therefore, at least one partition wall 24 can suppress warping of the base housing 20.

[0082] Also, in this embodiment, as shown in Figures 6 and 7, the first terminal unit 30A includes an inner terminal portion 60 consisting of at least one inner terminal 61, outer terminal portions 71, 72K, 72L surrounding the inner terminal portion 60, and a dielectric portion 80 holding the inner terminal portion 60 and the outer terminal portions 71, 72K, 72L. Therefore, compared to an embodiment in which the first terminal unit 30A does not include the outer terminal portions 71, 72K, 72L, the connector 10 can be made more suitable for high-speed transmission.

[0083] In this embodiment, as shown in Fig. 6, the dielectric portion 80 is formed by insert molding using the inner terminal portion 60 as an insert component. As shown in Fig. 10, the dielectric portion 80 has an intervening portion 86K interposed between the inner terminal portion 60 and the outer terminal portions 71, 72K, 72L. Therefore, the dielectric portion 80 having the interposition portion 86K can be integrally formed.

[0084] Also, in this embodiment, as shown in Figures 6 and 7, the first terminal unit 30A includes a first inner terminal portion 60K, a second inner terminal portion 60L, outer terminal portions 71, 72K, 72L that surround the first inner terminal portion 60K and the second inner terminal portion 60L separately, and a dielectric portion 80 that holds the first inner terminal portion 60K, the second inner terminal portion 60L, and the outer terminal portions 71, 72K, 72L. Therefore, compared to an embodiment in which the first terminal unit 30A does not include the second inner terminal portion 60L, the number of terminal units 30A, 30B can be reduced.

[0085] In this embodiment, the dielectric portion 80 is formed by insert molding using the first inner terminal portion 60K and the second inner terminal portion 60L as insert parts, as shown in Fig. 6. As shown in Fig. 10, the dielectric portion 80 has a first intermediate portion 86K interposed between the first inner terminal portion 60K and the outer terminal portions 71, 72K, 72L, and a second intermediate portion 86L interposed between the second inner terminal portion 60L and the outer terminal portions 71, 72K, 72L. Therefore, the dielectric portion 80 having the first intermediate portion 86K and the second intermediate portion 86L can be integrally formed.

[0086] Incidentally, FIG. 3 can also be understood as showing a group of connector components 10 for manufacturing the connector 10. As shown in FIG. That is, the connector component group 10 includes multiple types (two types) of terminal units 30A, 30B including a first terminal unit 30A and a second terminal unit 30B having different functions, and a base housing 20 having at least one accommodating portion 25 for accommodating the terminal units 30A, 30B. The at least one accommodating portion 25 includes an accommodating portion 25 (shared accommodating portion 25) that can accommodate either the first terminal unit 30A or the second terminal unit 30B. Therefore, it is possible to manufacture connectors 10 having different arrangements of the terminal units 30A, 30B using the same structure of the base housing 20. This makes it easy to increase the variety of connectors 10. For example, the first terminal unit 30A may be accommodated in all of the multiple (six) shared accommodating portions 25 provided in the base housing 20. Alternatively, for example, the first terminal unit 30A may be accommodated in five of the six shared accommodating portions 25 provided in the base housing 20, and the second terminal unit 30B may be accommodated in the remaining shared accommodating portion 25.
