[0009] [Description of the embodiments of the present disclosure] First, the contents of the embodiments of the present disclosure will be listed and described. [1] An electrical connector according to one embodiment includes a plurality of conductors, a plurality of terminals, a carrier portion, and a housing. Each of the plurality of conductors extends along a first direction and is arranged to be aligned in a second direction intersecting the first direction. Each of the plurality of terminals extends along a third direction intersecting the first and second directions and is arranged to be aligned in the second direction, and is configured to be electrically connected to a corresponding conductor among the plurality of conductors. The carrier portion is adjacent to a base end of each of the plurality of terminals and extends in the second direction. The housing accommodates a tip end of each of the plurality of conductors, the plurality of terminals, and the carrier portion. In this electrical connector, a ground terminal used as a ground line among the plurality of terminals is connected to the carrier portion, and a signal terminal used as a signal line among the plurality of terminals is not connected to the carrier portion.

[0010] This electrical connector has a carrier portion adjacent to the base end of each of the multiple terminals, and the ground terminal is connected to the carrier portion. In this case, the ground is stabilized by integrating the ground terminal with the carrier portion, so that the effect of crosstalk can be reduced and the communication performance of signals propagating through the signal terminals, etc. can be improved.

[0011] [2] In the electrical connector of [1] above, the tip of each of the plurality of terminals may be configured to be elastically deformable, which can stabilize the connection to the electrode pads on the board when the electrical connector is mounted on the board.

[0012] [3] The electrical connector of [1] or [2] above may further include a locking structure configured to fix the carrier part to the housing. In this case, even if an external force is applied to the multiple terminals, the external force can be received by the housing via the carrier part connected to the multiple terminals. This can distribute the external force and stabilize the electrical connection of the multiple terminals to the electrode pads, etc.

[0013] [4] In any of the electrical connectors [1] to [3] above, the housing may have a metallic outer shell, and the carrier part may be electrically connected to the outer shell and fixed by the outer shell. By connecting the carrier part to the metallic outer shell, the ground can be further stabilized, and communication performance can be further improved. In addition, by fixing the carrier part to the outer shell, even if an external force is applied to the multiple terminals, the external force can be dispersed, and the electrical connection of the multiple terminals to the electrode pads, etc. can be stabilized.

[0014] [5] Any of the electrical connectors described in [1] to [4] above may further include a relay member that electrically connects the base end of each of the multiple terminals to the tip end of each of the multiple conductors. In this case, the position of the base end of each of the multiple terminals can be adjusted by changing the size and position of the relay member. This makes it possible to adjust the position of the tip end of each of the multiple terminals. As a result, even if the multiple terminals are arranged in a multi-pole arrangement, each terminal can be stably electrically connected to the corresponding electrode pad.

[0015] [6] A method of manufacturing an electrical connector according to one embodiment includes the steps of: preparing a terminal member having a plurality of terminals and a first carrier portion connected to a base end of each of the plurality of terminals; preparing a housing for the electrical connector configured to accommodate the plurality of terminals; attaching the terminal member to the housing such that a tip end of each of the plurality of terminals is in a predetermined position relative to the housing; and cutting between the base end and the first carrier portion of a signal terminal among the plurality of terminals that is used as a signal line.

[0016] In this method of manufacturing an electrical connector, the base end of a signal terminal used as a signal line among the multiple terminals is cut between the first carrier part. In this case, the ground terminal among the multiple terminals remains integrated with the carrier part and the ground is stable, so that an electrical connector can be easily obtained that reduces the influence of crosstalk and improves the communication performance of signals propagating through the signal terminals, etc. Note that the first carrier part here may be a carrier part for sending a product from a reel on a processing machine when manufacturing the terminals, or may be a separate member. When the first carrier part is a carrier part for sending a product from a reel, the manufacturing of the electrical connector becomes easier and the manufacturing cost can be reduced.

[0017] [7] In the method for manufacturing an electrical connector according to [6] above, the terminal member may have a second carrier portion connected to the tip end of each of the multiple terminals. The method for manufacturing an electrical connector may further include a step of separating the second carrier portion from the multiple terminals. In this case, the terminal member can be subjected to various manufacturing steps in a state in which both ends of the multiple terminals are fixed by the first carrier portion and the second carrier portion, so that even if there are a large number of terminals, the electrical connector can be easily manufactured. The second carrier portion here may be a carrier portion for sending a product from a reel on a processing machine when manufacturing the terminals, or may be a separate member. When the first carrier and the second carrier portion are carrier portions at both ends for sending a product from a reel, the electrical connector can be manufactured even easier and the manufacturing cost can be further reduced.

[0018] [8] The method for manufacturing an electrical connector according to [7] above may further include a step of bending the multiple terminals while the first carrier portion and the second carrier portion are connected to the multiple terminals. In this case, the multiple terminals can be easily bent, and uniformity of the bending can be ensured. Thus, an electrical connector having stable communication performance can be easily obtained.

[0019] [Details of the embodiment of the present disclosure] Specific examples of electrical connectors according to embodiments of the present disclosure will be described below with reference to the drawings. In the following description, the same elements or elements having the same functions will be designated by the same reference numerals, and duplicated descriptions will be omitted. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0020] FIG. 1 is a perspective view showing an electric connector according to an embodiment. FIG. 2 is a cross-sectional perspective view of the electric connector shown in FIG. 1. FIG. 3 is a cross-sectional view of the electric connector shown in FIG. 1. As shown in FIGS. 1 to 3, the electric connector 1 includes an electric cable 10, a plurality of terminals 20, a carrier portion 30, a relay member 40, and a housing 50. In this embodiment, for example, four electric cables 10 are provided, but one or more electric cables 10 may be provided. The electric cables 10 are arranged in order in the Z direction. The plurality of terminals 20, the carrier portion 30, and the relay member 40 are provided corresponding to each electric cable 10. The electric connector 1 is mounted on, for example, a substrate 60, and each of the plurality of terminals 20 is electrically connected to an electrode pad 65 (see FIG. 4) provided on the substrate 60.

[0021] The electric cable 10 has a plurality of electric wires 11 and a covering portion 12 covering the plurality of electric wires 11. Each of the plurality of electric wires 11 is formed of a metal such as copper, and is used as a signal line or a ground line. The plurality of electric wires 11 extend along the X direction (first direction). The plurality of electric wires 11 provided in the same electric cable 10 are arranged so as to be lined up in the Y direction (second direction). One electric cable 10 may include, for example, 2 to 200 electric wires 11. The covering portion 12 is a member that covers the portions of the plurality of electric wires 11 except for the tip portions 11a. The length of the tip portions 11a in the X direction is, for example, about 1 mm, but can be adjusted in consideration of the mounting strength and transmission characteristic specifications of each component. The material of the covering portion 12 is, for example, a resin such as polyester. The electric cable 10 is formed by integrating the plurality of electric wires 11 lined up in the Y direction with the covering portion 12. The electrical cable 10 is, for example, a flexible flat cable (FFC).

[0022] Each of the multiple terminals 20 is formed of a metal such as copper, and is used as a signal line or a ground line. Each of the multiple terminals 20 extends along the Z direction (third direction). The multiple terminals 20 corresponding to each electric cable 10 (the multiple electric wires 11 included therein) are arranged to be lined up in the Y direction. The multiple terminals 20 corresponding to one electric cable 10 may include, for example, 2 to 200 terminals 20.

[0023] The base end 21 of each of the multiple terminals 20 in the Z direction is held by the relay member 40. For example, each base end 21 is solder-mounted to the relay member 40. The base end 21 is electrically connected to a corresponding electric wire 11 (tip end 11a) of the multiple electric wires 11 in the pattern wiring on the relay member 40. Although details will be described later, a ground terminal 20G used as a ground line among the multiple terminals 20 is connected to the carrier part 30 (see FIG. 5). On the other hand, a signal terminal 20S used as a signal line among the multiple terminals 20 is not connected to the carrier part 30. In other words, the signal terminal 20S is disconnected from the carrier part 30.

[0024] As shown in Fig. 3 and Fig. 4, the tip portion 22 of each of the multiple terminals 20 is configured to be elastically deformable in the Z direction, and is, for example, J-shaped. The tip portion 22 is configured to contact a corresponding electrode pad 65 among the multiple electrode pads 65 on the substrate 60 in an elastically deformed state. The tip portion 22 faces the main surface 61 of the substrate 60 at the bottom surface 51 of the housing 50. Before contacting the electrode pad 65, the tip portion 22 protrudes from the bottom surface of the housing 50 (see the shape indicated by the dotted line in Fig. 4). For example, the length by which the tip portion 22 protrudes from the bottom surface 51 may be 10 µm or more and 1000 µm or less, for example, 200 µm.

[0025] Referring again to FIG. 3, the relay member 40 is a member for relaying electrical connection between the plurality of electric wires 11 and the plurality of terminals 20. In the present embodiment, as an example, four electric cables 10 are provided, so that the electric connector 1 is provided with four relay members 40, but this is not limited thereto. The relay member 40 has, for example, a plate shape, and is, for example, a paddle card. The plurality of relay members 40 extend along the X direction and the Y direction. The plurality of relay members 40 are lined up along the Z direction. Each relay member 40 holds each base end 21 of the plurality of terminals 20 lined up in the Z direction. The pattern wiring of the relay member 40 is electrically connected to each tip end 11a of the plurality of electric wires 11 lined up in the Y direction and each base end 21 of the plurality of terminals 20 lined up in the Y direction.

[0026] The housing 50 is a substantially rectangular parallelepiped member that holds the tip portions 11a of the electric wires 11, the terminals 20, the carrier portion 30, and the relay member 40. A metal outer shell 57 may be provided on the outside of a housing body 56 of the housing 50. The housing body 56 of the housing 50 is formed of a resin such as polyphenylene sulfide (PPS). The housing 50 further has a plurality of holding holes 52, a plurality of recesses 53 (see FIG. 4), and a plurality of holes 54 (see FIG. 4). The plurality of holding holes 52 extend along the X direction and the Y direction, respectively. The plurality of holding holes 52 are aligned in the Z direction. Each holding hole 52 opens at a rear end surface 55 and extends from the rear end surface 55 to the inside of the housing 50. Each of the plurality of holding holes 52 holds an electric cable 10 and a relay member 40. For example, the relay member 40 is fixed to the inner wall of the holding hole 52 of the housing 50 by press-fitting, adhesive, or the like. Thus, the housing 50 holds the tip ends 11 a of the multiple electric wires 11 , the multiple terminals 20 , and the relay member 40 .

[0027] The multiple recesses 53 (see FIG. 4) are open at the bottom surface 51. The multiple recesses 53 each extend along the Y direction. The multiple recesses 53 are lined up in the X direction. The multiple holes 54 each extend along the Z direction. Each recess 53 communicates with a corresponding one of the multiple holding holes 52 via a corresponding one of the multiple holes 54.

[0028] Each of the multiple terminals 20 extends from the bottom of the holding hole 52 to the inside of the recess 53 via the hole 54. Therefore, by adjusting the position of the relay member 40 in the X direction, the position of the tip portion 22 of each terminal 20 held by the relay member 40 in the Z direction can be adjusted. This makes it possible to adjust the length by which the tip portion 22 of each terminal 20 protrudes from the bottom surface 51 of the housing 50, and therefore makes it possible to adjust the amount of spring displacement of the tip portion 22 of each terminal 20 when the electrical connector 1 is attached to the board 60.

[0029] Here, with reference to FIG. 5, the carrier part 30 connected to some of the terminals 20 will be described. FIG. 5 is a perspective view showing the terminals 20 and the carrier part 30 in the electrical connector 1, and is a view of a part of the electrical connector 1 seen from the bottom surface 51. FIG. 5 shows one set of the terminals 20 and the carrier part 30. The terminals 20 of other sets of the terminals 20 and the carrier part 30 have different lengths in the Z direction, but the other configurations are similar. As shown in FIG. 5, the carrier part 30 is a metal plate-like member extending in the Y direction, and is configured as being integrated with the terminals 20 (see FIG. 6 described later for details). However, the carrier part 30 and the terminals 20 do not have to be integrated. The carrier part 30 is connected to the ground terminal 20G used as a ground line among the terminals 20. On the other hand, the carrier part 30 is not connected (disconnected) to the signal terminal 20S used as a signal line among the terminals 20.

[0030] Next, a method for manufacturing the electrical connector 1 using the terminal member S shown in FIG. 6 will be described. The terminal member S is a member including the above-mentioned multiple terminals 20 and the carrier portion 30. In this manufacturing method, first, the electric cable 10 is prepared. Also, as shown in FIG. 6, a terminal member S for forming the terminals 20 is prepared. The terminal member S has multiple terminals 20, a carrier portion 30 (first carrier portion) connected to the base end portion 21 of each of the multiple terminals 20, and a carrier portion 35 (second carrier portion) connected to the tip end portion 22 of each of the multiple terminals 20. As the carrier portions 30 and 35 connected to both ends of the terminals 20, a member (carrier portion) for feeding the terminal reel that is fed in sequence when manufacturing the terminals 20 may be used as it is. This makes it possible to facilitate the following manufacturing process. However, the carrier portions 30 and 35 may be provided separately. Furthermore, a housing 50 for the electrical connector configured to accommodate the tip portion 11a of the electric cable 10 (multiple electric wires 11), the multiple terminals 20, etc. is prepared. The relay member 40 is attached to the housing 50 .

[0031] Next, the terminal members S are attached to the inside of the housing 50 so that the tip portions 22 of the terminals 20 are at predetermined positions relative to the housing 50 (bottom surface 51). This causes each tip portion 22 to slightly protrude from the bottom surface 51 of the housing 50 (see FIG. 5). At this stage, the carrier portion 30 is connected to the base ends 21 of the terminals 20, and the carrier portion 35 is connected to each tip portion 22 of the terminals 20.

[0032] Subsequently, if necessary, a bending process may be performed on the terminals 20 while the carrier portion 30 and the carrier portion 35 are connected to the terminals 20. By such a bending process, the shape of the terminals 20 along the longitudinal direction can be changed into a desired shape.

[0033] Next, when the attachment of the terminal members S to the housing 50 is completed, the carrier portion 35 is separated from the plurality of terminals 20. In this separation, all of the plurality of terminals 20 are separated by cutting between the carrier portion 35 and each of the terminals 20.

[0034] Next, when the separation of the carrier portion 35 is completed, the signal terminals 20S, which are used as signal lines among the multiple terminals 20, are cut between the carrier portion 30. However, the ground terminals 20G, which are used as ground lines among the multiple terminals 20, are not cut between the carrier portion 30 and the ground terminals 20. As a result, the ground terminals 20G and the carrier portion 30 remain connected, and the ground structure is integrated.

[0035] Thereafter, the electrical connector 1 is produced by carrying out the same process for the required number of electrical cables 10. If the carrier parts 30 and 35 are used for feeding products from a terminal reel, the electrical connector can be easily manufactured and the manufacturing cost can be reduced. In addition, the manufacturing efficiency can be further improved by using the feeding holes in the carrier parts 30 and 35.

[0036] As described above, the electrical connector 1 according to this embodiment has the carrier portion 30 adjacent to the base end portion 21 of each of the multiple terminals 20, and the ground terminal 20G is connected to the carrier portion 30. The ground terminal 20G is integrated with the carrier portion 30, which stabilizes the ground in the electrical connector 1. This electrical connector 1 can reduce the effects of crosstalk and improve the communication performance of signals propagating through the signal terminals 20S, etc.

[0037] In the electrical connector 1, the tip portion 22 of each of the multiple terminals 20 is configured to be elastically deformable. This allows the connection to the electrode pads 65 on the substrate 60 to be stabilized when the electrical connector 1 is mounted on the substrate 60.

[0038] The electrical connector 1 further includes a relay member 40 that electrically connects the base end 21 of each of the multiple terminals 20 to the tip end 11a of each of the multiple electric wires 11. By changing the size and position of such relay member 40, the position of the base end 21 of each of the multiple terminals 20 can be adjusted. This makes it possible to adjust the position of the tip end 22 of each of the multiple terminals 20. As a result, when the multiple terminals 20 are arranged in a multi-pole arrangement, each terminal 20 can be electrically connected more stably to each electrode pad 65 corresponding to that terminal.

[0039] The manufacturing method of the electrical connector according to this embodiment includes the steps of preparing a terminal member S having a plurality of terminals 20 and a carrier portion 30 connected to the base end 21 of each of the plurality of terminals 20, preparing a housing 50 for the electrical connector configured to accommodate the plurality of terminals 20, attaching the terminal member S to the housing 50 so that the tip end 22 of each of the plurality of terminals 20 is in a predetermined position relative to the housing 50 (so that it protrudes slightly from the bottom surface 51), and cutting between the base end 21 and the carrier portion 30 of a signal terminal 20S used as a signal line among the plurality of terminals 20.

[0040] In this manufacturing method for an electrical connector, the base end 21 of the signal terminal 20S, which is used as a signal line among the multiple terminals 20, is cut between the carrier portion 30 and the base end 21. As a result, the ground terminal 20G among the multiple terminals 20 is integrated with the carrier portion 30, stabilizing the ground. This makes it possible to easily obtain an electrical connector that reduces the effects of crosstalk and improves the communication performance of signals propagating through the signal terminals 20S, etc.

[0041] In the manufacturing method of the electrical connector 1, the terminal member S further has a carrier portion 35 connected to the tip portion 22 of each of the multiple terminals 20. This manufacturing method of the electrical connector further includes a step of separating the carrier portion 35 from the multiple terminals 20. This allows the terminal member S to undergo various processes (e.g., a collective bending process, etc.) in a state in which the multiple terminals 20 are arranged by the carrier portion 30 and the carrier portion 35. Therefore, even if the electrical connector 1 has a large number of terminals, it is possible to easily manufacture the electrical connector.

[0042] The manufacturing method of the electrical connector may further include a step of bending the terminals while the carrier portion 30 and the carrier portion 35 are connected to the terminals 20. In this case, the bending process can be easily performed on the multiple terminals 20, and uniformity of the bending process can be ensured. Therefore, an electrical connector having stable communication performance can be easily obtained.

[0043] Although the embodiments of the present disclosure have been described in detail above, the present disclosure is not limited to the above-described embodiments and can be applied to various embodiments.

[0044] For example, as shown in FIG. 7, the electrical connector 1 may be provided with a locking structure T configured to fix the carrier part 30 to the housing 50. The locking structure T may be configured to provide a hole or a recess penetrating the carrier part 30 and a protrusion at a corresponding location on the housing 50. The protrusion fits into the hole or the recess, thereby locking the carrier part 30 to the housing 50. Conversely, the locking structure T may be configured to provide a protrusion protruding toward the housing 50 on the carrier part 30 and a through hole or a recess that fits into the protrusion at a corresponding location on the housing 50. With this configuration, even if an external force is applied to the multiple terminals 20, the external force can be received by the housing 50 via the carrier part 30 connected to the multiple terminals 20. Therefore, the external force can be dispersed to stabilize the electrical connection of the multiple terminals 20 to the electrode pads 65, etc.

[0045] 8, in the electrical connector 1, in the housing 50 having a metallic outer shell 57, the carrier portion 30 (end portion 31) may be electrically connected to the outer shell 57 and fixed by the outer shell 57. By connecting the carrier portion 30 to the metallic outer shell 57, the ground is further stabilized, and the communication performance can be further improved. Furthermore, by fixing the carrier portion 30 to the outer shell 57, even if an external force is applied to the multiple terminals 20, the external force can be dispersed, and the electrical connection of the multiple terminals 20 to the electrode pads 65, etc. can be stabilized.
