Description

The present disclosure relates to electrical connectors and connector arrangements.

2. Description of the Related Art There is known a connector device that electrically connects a signal transmission member and an electric circuit of a substrate by fitting a plug connector connected to the signal transmission member and a receptacle connector mounted on the substrate (for example, See Patent Document 1). The receptacle connector of Patent Document 1 includes an outer conductor that engages with a cylindrical conductor of a plug connector, an inner conductor that contacts the conductor of the plug connector inside the outer conductor, and an insulator.

Patent 5024449

Here, in the receptacle connector described in Patent Document 1, the inner conductor has a lead portion that is led out to the outside (in the direction of the outer conductor) so that it can come into contact with the terminal of the substrate. The lead-out portion is led out beyond the outer conductor. In such a configuration, when the plug connector and the receptacle connector are fitted together, the conductor (outer conductor) of the plug connector and the lead-out portion of the receptacle connector are close to each other. As a result, electromagnetic coupling is likely to occur between the outer conductor of the plug connector and the lead-out portion of the receptacle connector, electromagnetic field leakage occurs, and insertion loss between the plug connector and the receptacle connector increases.

The present disclosure has been made in view of the above circumstances, and an object thereof is to provide an electrical connector and a connector device capable of suppressing insertion loss.

An electrical connector according to one aspect of the present disclosure is an electrical connector mounted on a board, and is electrically connected to a cylindrical first contact that is fitted to a ground contact of a mating connector and a signal contact of the mating connector. and a first insulating housing that holds the first contact and the second contact in an insulated state. The second contact includes a center conductor that contacts the signal contact of the mating connector, a substrate connecting portion extending to be pulled out from the first contact and connected to the terminal portion of the substrate, the substrate connecting portion being housed in a region surrounded by the first contacts and having at least a portion thereof exposed to the outside; Exposed.

In the electrical connector according to one aspect of the present disclosure, the substrate connecting portion extending so as to be pulled out from the central conductor and connected to the terminal portion of the substrate is connected to the cylindrical first contact that is fitted to the ground contact of the mating connector. Contained within an enclosed area. As a result, when the electrical connector of the present disclosure is mated with the mating connector, the board connection portion connected to the center conductor is arranged at a position spaced apart from the ground contact of the mating connector. As a result, the ground contact of the mating connector and the board connection portion are unlikely to be electromagnetically coupled, and the insertion loss between the electrical connector and the mating connector can be suppressed. Furthermore, in the electrical connector according to one aspect of the present disclosure, at least a portion of the board connecting portion is exposed to the outside. As a result, even when adopting a configuration in which the substrate connecting portion is accommodated in the area surrounded by the first contacts (that is, the length of the drawer is small) as in the electrical connector according to one aspect of the present disclosure, It is possible to easily confirm the position of the board connecting portion.

At least a portion of the board connecting portion may be arranged so as to be visible when viewed in a first direction, which is a fitting direction with the mating connector and a direction from the mating connector toward the board. This makes it possible to easily and reliably confirm the position of the board connection portion when mounting the electrical connector on the board and when fitting the mating connector to the electrical connector.

The first insulating housing may be formed with a notch that exposes at least a portion of the board connecting portion to the outside. By adopting such a configuration, only a portion of the first insulating housing necessary for exposing the board connecting portion is cut out while ensuring insulation between the first contact and the second contact by the first insulating housing. Therefore, it is possible to reliably expose a part of the board connecting portion.

The notch portion may be formed so as to expose the contact area with the terminal portion in the substrate connection portion to the outside. As a result, the contact portion between the substrate connection portion and the terminal portion can be reliably visually recognized.

The first insulating housing may be provided only in a region closer to the central conductor than the tip of the board connecting portion in the extending direction of the board connecting portion. This makes it possible to simplify the configuration of the first insulating housing for exposing a portion of the substrate connecting portion, as compared with the case of forming a notch in the first insulating housing, for example. Manufacturability can be improved.

A connector device according to an aspect of the present disclosure includes a first connector mounted on a substrate and a second connector connected to a signal transmission member and mated with the first connector, The first connector has a first contact that is a cylindrical ground contact, a second contact that is a signal contact, and a first insulating housing that holds the first contact and the second contact in an insulated state. The second connector includes a cylindrical third contact that is fitted to the first contact, a fourth contact that is electrically connected to the second contact, and a second contact that holds the third contact and the fourth contact in an insulated state. an insulating housing, wherein the second contact has a center conductor that contacts the fourth contact, and a substrate connection portion that extends so as to be pulled out from the center conductor and is connected to a terminal portion of the substrate; The board connecting portion is accommodated in a region surrounded by the third contacts when the first connector and the second connector are mated, and when the first connector and the second connector are not mated. , at least a portion of which is exposed to the outside.

The inner peripheral surface of the fitting portion 11a is in contact with the outer peripheral surface of the insulating housing 13 except for the area corresponding to the notch portion 13x of the insulating housing 13 (see FIG. 3A). A recessed portion 11x that is recessed radially inward (toward the center of the fitting portion 11a) is formed over the entire circumference of the outer peripheral surface of the fitting portion 11a (see FIG. 3D). The fitting portion 11a is fitted to the ground contact 101 of the plug connector 100 by engaging the concave portion 11x with the convex portion 101x (see FIG. 8B) formed on the outer periphery of the ground contact 101 of the plug connector 100. (details will be described later). The fitting portion 11a is provided so as to stand from the base portions 11b, 11b. The base portions 11b, 11b are arranged so as to place the fitting portion 11a thereon, and extend in the X direction facing each other in the Y direction. The bases 11b, 11b are arranged on the substrate 200 so as to be connected to the ground terminal portion 202 of the substrate 200, as shown in FIG.

(signal contact)
The signal contact 12 is electrically connected to the signal contact 102 of the plug connector 100 (see FIG. 8(b)). A signal contact 12 is mounted in an insulating housing 13 . The signal contact 12 is a conductor for signal transmission formed of, for example, a thin metal member. The signal contact 12 has a central conductor 12a and a substrate connecting portion 12b, as shown in FIGS. 5(a) to 5(c).

The center conductor 12a is a conductor that contacts the signal contact 102 of the plug connector 100 (see FIG. 8(b)). The central conductor 12a is formed in a cylindrical shape (cylindrical shape) having an axial direction in the Z direction, and contacts the signal contact 102 on its outer peripheral surface (see FIG. 8B). The central conductor 12a is attached to the support portion 13y of the insulating housing 13 (see FIG. 3(c)). The substrate connection portion 12b extends so as to be pulled out from the central conductor 12a and is connected to the signal terminal portion 201 (see FIG. 2) of the substrate 200. As shown in FIG. That is, the board connection portion 12b is continuous with the lower end of the central conductor 12a and forward in the X direction (the direction approaching the fitting portion 11a and the direction away from the inner conductor SC1 of the coaxial cable SC (see FIG. 8B). )) and contacts the signal terminal portion 201 (see FIG. 2) of the substrate 200. As shown in FIG. Although the shape of the board connection portion 12b is not limited, for example, as shown in FIGS. It has a substantially rectangular shape smaller than the height.

As shown in FIG. 3A, the board connecting portion 12b is housed in a region surrounded by the fitting portion 11a of the ground contact 11, and the exposing portion 12x, which is the tip (front end) portion thereof, is exposed to the outside. exposed to Being exposed to the outside means, for example, being visible from the outside. More specifically, the exposed portion 12x, which is a part of the board connecting portion 12b, is arranged so as to be visible when viewed in the Z direction, which is the direction from the plug connector 100 toward the board 200 (first direction). there is Such exposure of the exposed portion 12x is achieved by forming a notch portion 13x in the insulating housing 13 (details will be described later). The exposed portion 12x is a contact area with the signal terminal portion 201 (see FIG. 2) in the board connection portion 12b.

(insulating housing)
The insulating housing 13 holds the ground contact 11 and the signal contact 12 in an insulated state. That is, the insulating housing 13 is an insulator for insulating between the ground contact 11 and the signal contact 12 . The insulating housing 13 has a body portion 13a, first extension portions 13b, 13b, and a second extension portion 13c, as shown in FIGS. 6(a) to 6(c).

The main body portion 13a is a member that is formed in a substantially disk shape except for a formation region of a notch portion 13x, which will be described later, and is accommodated inside the fitting portion 11a. The outer peripheral surface of the main body portion 13a is in contact with the inner peripheral surface of the fitting portion 11a except for the area where the notch portion 13x is formed (see FIG. 3A). The body portion 13a is formed with a notch portion 13x for exposing the exposed portion 12x of the substrate connection portion 12b to the outside. That is, the notch portion 13x is formed so as to expose the exposed portion 12x, which is the contact area with the signal terminal portion 201 in the substrate connection portion 12b, to the outside. The length (width) of the notch 13x in the Y direction is such that the exposed portion 12x and the contact area with the exposed portion 12x in the signal terminal portion 201 contacting the exposed portion 12x are exposed (visible). It is formed longer than the Y-direction length (width) of the exposed portion 12x and the signal terminal portion 201 (see FIG. 3A). The notch portion 13x may be formed only in a region of the body portion 13a where the exposed portion 12x is exposed. Therefore, as shown in FIG. 3(a), even if the position in the X direction is the same as or in front of the exposed portion 12x, the insulating housing 13 is in the Y direction of the exposed portion 12x. A portion of the region outside in the Y direction from both ends in the direction is not cut out.

As shown in FIGS. 6(a) to 6(c), the body portion 13a has a support portion 13y at its central portion for mounting the center conductor 12a. The support portion 13y is provided in the central portion of the main body portion 13a and is a cylindrical member extending in the Z direction. The first extending portions 13b, 13b are continuous with the front end in the X direction of the main body portion 13a, and extend forward in the X direction facing each other in the Y direction. The first extending portions 13b, 13b respectively extend forward in the X direction along the inner edges of the base portions 11b, 11b of the ground contact 101 (see FIG. 3(c)). The second extending portion 13c continues to the rear end of the body portion 13a in the X direction and extends rearward in the X direction along the base portions 11b and 11b so as to be sandwiched between the base portions 11b and 11b (see FIG. 3 ( a) see).

(Manufacturing process of receptacle connector)
Next, the manufacturing process (molding process) of the receptacle connector 10 will be described with reference to FIGS. 7(a) to 7(f).

In the manufacturing process of the receptacle connector 10, first, as shown in FIG. 7A, the ground contact 11 and the signal contact member 112, which are parts to be mounted on a mold (not shown), are prepared. The signal contact member 112 is a member that becomes the signal contact 12 through a process described later, and has an extension portion 112b that is a longer version of the board connection portion 12b. Then, as shown in FIG. 7B, resin (housing material) is injected into the mold (not shown) with the ground contact 11 and the signal contact member 112 attached to the mold (not shown). be done. FIG. 7(c) shows the state in which the resin is injected into the mold and the insert molding is completed, that is, the state in which the insulating housing 13 is formed. As shown in FIG. 7(d), the signal contact member 112 is formed with a cut line 112x. As shown in FIG. 7(e), the signal contact 12 having the substrate connection portion 12b is broken off at the cut line 112x at the area ahead of the cut line 112x, as shown in FIG. 7(f). is formed. The receptacle connector 10 is manufactured by the above steps. The manufacturing process described is merely an example, and the receptacle connector 10 may be manufactured by other manufacturing processes.

[Connector Device (Mating State of Receptacle Connector and Plug Connector)]
Next, the connector device 1 in which the receptacle connector 10 and the plug connector 100 are fitted together will be described in detail with reference to FIGS. 8(a) and 8(b).

8B, the plug connector 100 has a ground contact 101 (third contact), a signal contact 102 (fourth contact), and an insulating housing 103 (second insulating housing). is doing. The ground contact 101 is a cylindrical contact member that fits into the ground contact 11 . A ground contact 101 is connected to the outer conductor of the coaxial cable SC. A convex portion 101x is formed on the lower end side of the ground contact 101 and protrudes radially inward (toward the center of the cylindrical shape of the ground contact 101) over the entire circumference. Signal contact 102 is electrically connected to signal contact 12 . The signal contact 102 is mounted inside an insulating housing 103 and is connected to the inner conductor SC1 of the coaxial cable SC and to the central conductor 12a of the signal contact 12 of the receptacle connector 10. FIG. The insulating housing 103 has a cylindrical shape and holds the ground contact 101 and the signal contact 102 in an insulated state. The outer peripheral surface of the insulating housing 103 is in contact with the inner peripheral surface of the ground contact 101 .

As shown in FIG. 8B, the receptacle connector 10 and the plug connector 100 are mated with each other by the concave portion 11x of the fitting portion 11a of the receptacle connector 10. As shown in FIG. In the mated state, the signal contact 102 of the plug connector 100 is in contact with the center conductor 12a of the receptacle connector 10. As shown in FIG. Thus, the signal contact 102 connected to the inner conductor SC1 of the coaxial cable SC and the central conductor 12a connected to the signal terminal portion 201 (see FIG. 2) of the substrate 200 via the substrate connection portion 12b are connected. A signal transmission circuit of the connector device 1 is configured by the contact. Also, in the mated state, the ground contact 101 of the plug connector 100 is in contact with the mating portion 11a of the receptacle connector 10 . In this way, the ground contact 101 connected to the outer conductor of the coaxial cable SC and the fitting portion 11a connected to the ground terminal portion 202 (see FIG. 2) of the substrate 200 via the base portions 11b, 11b are A ground circuit of the connector device 1 is formed by the contact.

In the connector device 1, in the mated state, as shown in FIG. 8(b), the board connecting portion 12b is accommodated in the area surrounded by the ground contacts 101 of the plug connector 100, and In the unfitted state, as shown in FIG. 3A, the exposed portion 12x of the board connecting portion 12b is exposed to the outside (that is, arranged so as to be visible).

[Effect]
Next, the effects of the receptacle connector 10 and connector device 1 described above will be described.

First, a connector device 501 according to a comparative example will be described with reference to FIGS. 9(a) and 9(b). The connector device 501 is, like the connector device 1 of the present embodiment, a connector device that electrically connects a signal transmission member and an electric circuit of a substrate. A receptacle connector 510 of the connector device 501 has a ground contact 511, a signal contact 512, and an insulating housing 513, as shown in FIG. 9(a). The signal contact 512 has a central conductor 512a and a board connecting portion 512b drawn out from the central conductor 512a. Here, in the connector device 501 according to the comparative example, when mounting the receptacle connector 510 on the substrate, etc., the visibility (easiness of confirmation) of the substrate connection portion 512b connected to the signal terminal portion of the substrate is improved. , the substrate connecting portion 512b is pulled out beyond the ground contact 511. As shown in FIG. That is, since the area between the ground contact 511 and the signal contact 512 is filled with the insulating housing 513, the board connecting part 512b is positioned outside the ground contact 511 in order to improve the visibility of the board connecting part 512b. (see FIG. 9(a)). In such a connector device 501, as shown in FIG. 9(b), when the receptacle connector 510 and the plug connector 600 are mated, the board connection portion 512b is surrounded by the ground contacts 601 of the plug connector 600. It is conceivable that the structure extends further outward beyond the region. In this case, the adjacent area between the ground contact 601 of the plug connector 600 and the substrate connection portion 512b of the receptacle connector 510 becomes large, and electromagnetic coupling is likely to occur between the ground contact 601 and the substrate connection portion 512b. This increases the insertion loss between plug connector 600 and receptacle connector 510 .

In order to solve the problem of the connector device 501 according to the comparative example, the receptacle connector 10 of the connector device 1 of this embodiment has the following configuration. That is, the receptacle connector 10 is an electrical connector mounted on a substrate 200, as shown in FIG. 3(a). a signal contact 12 electrically connected to the signal contact 102 of the plug connector 100; and an insulating housing 13 holding the ground contact 11 and the signal contact 12 in an insulated state. has a central conductor 12a that contacts the signal contact 102 of the plug connector 100, and a substrate connecting portion 12b that extends so as to be pulled out from the central conductor 12a and is connected to the signal terminal portion 201 of the substrate 200, and the substrate The connecting portion 12b is accommodated in a region surrounded by the fitting portion 11a, and at least a portion (specifically, the exposed portion 12x) is exposed to the outside.

In the receptacle connector 10 as described above, the substrate connection portion 12b extending so as to be pulled out from the central conductor 12a and connected to the signal terminal portion 201 of the substrate 200 has a cylindrical shape that is fitted to the ground contact 101 of the plug connector 100. It is housed within a region surrounded by the fitting portion 11a (inside the fitting portion 11a). As shown in FIG. 8(b), the ground contact 101 of the plug connector 100 is arranged outside the fitting portion 11a. Therefore, when the receptacle connector 10 is mated with the plug connector 100, the board connecting portion 12b accommodated inside the mating portion 11a is arranged at a position spaced apart from the ground contacts 101 of the plug connector 100. It will happen. As a result, the ground contact 101 of the plug connector 100 and the board connection portion 12b are unlikely to be electromagnetically coupled, and the insertion loss between the receptacle connector 10 and the plug connector 100 can be suppressed. Here, as described above, in the connector device 501 according to the comparative example, the board connection portion 512b is drawn outward from the ground contact 511 in order to ensure the visibility (easiness of checking) of the board connection portion 512b. (see FIG. 9(a)). In the configuration in which the board connecting portion 12b is accommodated inside the fitting portion 11a as in the present embodiment, the insulating housing 13 is provided inside the fitting portion 11a, so that the board connecting portion 12b can be visually recognized. Gender can be an issue. In this regard, the receptacle connector 10 according to the present embodiment has a configuration in which the board connecting portion 12b is not only accommodated inside the fitting portion 11a, but also a portion of the board connecting portion 12b is exposed to the outside as the exposed portion 12x. It is As a result, even if the board connecting portion 12b is accommodated in the area surrounded by the fitting portion 11a (that is, the board connecting portion 12b is pulled out in a short length), the position of the board connecting portion 12b can be changed. can be easily verified.

In the receptacle connector 10, at least a portion of the board connection portion 12b is arranged so as to be visible when viewed in the first direction, which is the fitting direction with the plug connector 100 and the direction from the plug connector 100 toward the board 200. As a result, when mounting the receptacle connector 10 on the board 200 and when fitting the plug connector 100 to the receptacle connector 10, the position of the board connection portion 12b can be easily and reliably confirmed. can be done.

In the receptacle connector 10, the insulating housing 13 is formed with a notch portion 13x for exposing at least a portion (specifically, the exposed portion 12x) of the board connection portion 12b to the outside. By adopting such a configuration, while the insulating housing 13 reliably insulates between the ground contact 11 and the signal contact 12, the portion necessary for exposing the board connection portion 12b in the main body portion 13a of the insulating housing 13 is maintained. The exposed portion 12x can be reliably exposed by notching the only portion.

In the receptacle connector 10, the notch portion 13x is formed so as to expose the contact area with the signal terminal portion 201 in the board connection portion 12b to the outside. As a result, the contact portion between the substrate connection portion 12b and the signal terminal portion 201 can be visually recognized with certainty.

As mentioned above, although this embodiment was described, this invention is not limited to the said embodiment. For example, an example in which a notch is formed in the insulating housing of the receptacle connector as a configuration for exposing the board connecting portion has been described, but the configuration for exposing the board connecting portion is not limited to this. The receptacle connector 210 shown in FIGS. 10( a ) and 10 ( b ) has an insulating housing 213 . The insulating housing 213 is provided only in a region closer to the central conductor 12a than the tip (front end) of the board connecting portion 12b (that is, rearward in the X direction) in the extending direction of the board connecting portion 12b, that is, in the X direction. Even when such a configuration is adopted, it is possible to appropriately expose a portion of the board connection portion 12b, as in the case of forming the notch. In addition, in such a configuration, the configuration of the insulating housing 213 for exposing a part of the board connecting portion 12b can be simplified compared to the case of forming a notch in the insulating housing, for example. The manufacturability of H.213 can be improved.

Also, although it has been described that the board connecting portion is housed in the area surrounded by the ground contacts of the receptacle connector, the present invention is not limited to this. The receptacle connector 310 shown in FIGS. 11(a) and 11(b) has a substrate connecting portion 312b of a signal contact. The substrate connecting portion 312b is not entirely accommodated in the area surrounded by the ground contact 11, and part of it extends to the outside of the ground contact 11. As shown in FIG. Even if such a configuration is adopted, the area where the board connection portion 312b is surrounded by the ground contacts 101 of the plug connector 100 in the mated state like the connector device 301 shown in FIG. Since the ground contact 101 is housed inside (does not extend to the outside of the ground contact 101), an increase in the adjacent area between the ground contact 101 and the substrate connection portion 312b of the receptacle connector 310 is suppressed, and the receptacle connector 310 and the insertion loss of the plug connector 100 can be suppressed.
