[Diagram 2] FIG. 2 is a perspective view showing the connector device according to the embodiment. [Diagram 3] 3 is a cross-sectional view of the connector device taken along line III-III in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] [Embodiment] This embodiment relates to a connector device. In the following description, among the first, second, and third directions that intersect with each other, the first direction is referred to as the "connection direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the connection direction X, the width direction Y, and the height direction Z are mutually perpendicular. The connection direction X corresponds to the connection direction, the fitting direction, and the separation direction of the connector device and the mating connector. The width direction Y and the height direction Z correspond to the intersecting directions that intersect with the connection direction X. In addition, each direction used in the following description represents a direction in a state in which each part is assembled with each other, unless otherwise specified. Note that the orthogonal here includes substantially orthogonal.

[0011] As shown in Figs. 1 and 2, the connector device 1 is a connector device with an inner connector, and is used, for example, as a high-voltage connector for use in electric vehicles. The connector device 1 includes a female inner connector 2 and a male inner connector 3. Fig. 1 shows the connector device 1 in a state in which the female inner connector 2 and the male inner connector 3 are separated, and Fig. 2 shows the connector device 1 in a state in which the female inner connector 2 and the male inner connector 3 are connected. The connector device 1 is used, for example, by connecting it to a mating connector (not shown). The connector device 1 has, for example, a shield shell (not shown), which covers the periphery of the female inner connector 2 and the male inner connector 3.

[0012] The female inner connector 2 has a female housing 21 and a female terminal portion 22. The female housing 21 is a member that holds the female terminal portion 22, and is formed by resin molding, and has, for example, a block shape. In FIG. 1, the female housing 21 has a rectangular parallelepiped or approximately rectangular parallelepiped shape, but may have other shapes depending on the shape of the connector device 1, etc. The female housing 21 is formed by resin molding integrally with the female terminal portion 22. For example, the female housing 21 is formed by insert molding in which the female terminal portion 22 is inserted. Therefore, the female housing 21 and the female terminal portion 22 are integrated, and the formation of a gap between the female housing 21 and the female terminal portion 22 is suppressed. In addition, the female housing 21 and the female terminal portion 22 can be handled and managed as one part by being integrated.

[0013] The female terminal portion 22 is formed of a conductive member, and for example, two female terminal portions 22 are provided and arranged at positions spaced apart in the width direction Y. The female terminal portion 22 is formed in a ring shape and has a connection hole 221. In other words, the female terminal portion 22 is a ring body in which the connection hole 221 is formed in the connection direction X.

[0014] The male inner connector 3 has a male housing 31 and a male terminal portion 32. The male housing 31 is a member that holds the male terminal portion 32, and is formed by resin molding, and is, for example, block-shaped. In FIG. 1, the male housing 31 has a rectangular parallelepiped or approximately rectangular parallelepiped shape, but may have other shapes depending on the shape of the connector device 1. The male housing 31 is formed by resin molding integrally with the male terminal portion 32. For example, the male housing 31 is formed by insert molding in which the male terminal portion 32 is inserted. Therefore, the male housing 31 and the male terminal portion 32 are integrated, and the formation of a gap between the male housing 31 and the male terminal portion 32 is suppressed. Furthermore, the male housing 31 and the male terminal portion 32 can be handled and managed as one part by being integrated.

[0015] The male terminal portion 32 is formed of a conductive material, and for example, two male terminal portions 32 are provided and arranged at positions spaced apart in the width direction Y. The male terminal portion 32 is formed in a pin shape and is inserted into the female terminal portion 22 to connect with the female terminal portion 22. The tip portion 321 of the male terminal portion 32 has a tapered shape and is shaped to be easily inserted into the connection hole 221 of the female terminal portion 22. The male terminal portion 32 is held in the male housing 31 with its axial direction facing the connection direction X, and the tip portion 321 protrudes from the male housing 31. When the male housing 31 is connected to the female housing 21, the male terminal portion 32 is inserted into the connection hole 221 of the female terminal portion 22, and the female inner connector 2 and the male inner connector 3 are connected.

[0016] An electric wire 34 is connected to the male terminal portion 32. The electric wire 34 is, for example, a coated electric wire having an insulating coating portion provided around a conductor portion, and is attached to the rear end portion of the male terminal portion 32 by crimping or the like.

[0017] The connector device 1 includes a bolt 4. The bolt 4 is a fastening member for connecting the female inner connector 2 and the male inner connector 3. The bolt 4, for example, passes through the female housing 21 and is fastened to a nut portion 33 of the male housing 31. The bolt 4 is inserted between the two female terminal portions 22 and between the two male terminal portions 32 to perform fastening.

[0018] The female housing 21 has a recess 211 formed by, for example, recessing a surface intersecting the connection direction X. The recess 211 is recessed along the connection direction X. A ring member 23 is provided inside the recess 211. The ring member 23 is a member for inserting the bolt 4, and is disposed toward the connection direction X and provided so as to penetrate the female housing 21. The ring member 23 may be provided by being fitted into the female housing 21, or may be provided integrally with the female housing 21 when the female housing 21 is insert molded. The nut portion 33 is embedded in the male housing 31. The nut portion 33 may be provided by being fitted into the male housing 31, or may be provided integrally with the male housing 31 when the male housing 31 is insert molded.

[0019] 3, the female inner connector 2 is provided with a spring member 24. The spring member 24 is made of a conductive member, and is interposed between the female terminal portion 22 and the male terminal portion 32 when the female inner connector 2 and the male inner connector 3 are connected, and serves to electrically connect the female terminal portion 22 and the male terminal portion 32. In the connector device 1, there are cases where the female terminal portion 22 and the male terminal portion 32 are in direct contact with each other without providing the spring member 24, but by providing the spring member 24, the contact state or electrical connection between the female terminal portion 22 and the male terminal portion 32 can be stabilized.

[0020] The spring member 24 has a ring shape, is housed in the connection hole 221 of the female terminal portion 22, and is disposed along the inner circumference of the connection hole 221. For example, the spring member 24 is disposed in an annular groove 221A having an enlarged inner diameter in the connection hole 221. By disposing the spring member 24 in the annular groove 221A, it is possible to prevent the spring member 24 from moving in the connection direction X when the male terminal portion 32 is inserted into the female terminal portion 22.

[0021] The spring member 24 has, for example, two annular portions 241 spaced apart in the connection direction X, and a plurality of contact portions 242 that are spanned between the two annular portions 241 and spaced apart in the circumferential direction. The annular portions 241 contact the inner periphery of the connection hole 221 and contact the female terminal portion 22. The contact portion 242 is a leaf spring that is provided in the connection direction X, has a protruding portion 242A that protrudes toward the center of the connection hole 221, and the protruding portion 242A is brought into contact with the outer periphery of the male terminal portion 32. Note that the spring member may have a structure or shape other than that of the above-described spring member 24, as long as it can stabilize the contact state or electrical connection between the female terminal portion 22 and the male terminal portion 32.

[0022] Next, the assembly of the connector device 1 according to this embodiment will be described.

[0023] As shown in FIG. 1, the connector device 1 is assembled by connecting the male inner connector 3 and the female inner connector 2. The female inner connector 2 is a single component in which the female housing 21 and the female terminal portion 22 are integrated. Therefore, it is not necessary to assemble the female terminal portion 22 to the female housing 21, and the assembly process can be reduced. In addition, the number of components in the female inner connector 2 is reduced, making it easier to manage the components. In addition, since the female housing 21 and the female terminal portion 22 are integrated in the female inner connector 2, there is no gap between the female housing 21 and the female terminal portion 22. Therefore, the female inner connector 2 can be made smaller, and the female inner connector 2 can be easily handled when assembled.

[0024] In the male inner connector 3, the male housing 31 and the male terminal portion 32 are integrated into one component. Therefore, there is no need to assemble the male terminal portion 32 to the male housing 31, and the assembly process can be reduced. In addition, the number of components in the male inner connector 3 is reduced, making it easier to manage the components. In addition, since the male housing 31 and the male terminal portion 32 are integrated into the male inner connector 3, there is no gap between the male housing 31 and the male terminal portion 32. Therefore, the male inner connector 3 can be made smaller, and handling during assembly of the male inner connector 3 is easier.

[0025] In FIG. 1, the male inner connector 3 is disposed so as to face the female inner connector 2 with the male terminal portion 32 facing the female terminal portion 22. Then, the male inner connector 3 is brought close to the female inner connector 2, and the male terminal portion 32 is inserted into the female terminal portion 22. As shown in FIG. 3, the spring member 24 is accommodated in the female terminal portion 22, and the male terminal portion 32 is inserted into the spring member 24 and connected to the female terminal portion 22 via the spring member 24. This makes it possible to stabilize the electrical contact or connection state between the male terminal portion 32 and the female terminal portion 22. For example, if the male terminal portion 32 and the female terminal portion 22 are directly contacted without providing the spring member 24, there is a concern that the contact state between the male terminal portion 32 and the female terminal portion 22 will be unstable due to component tolerances, etc. In contrast, in the connector device 1 according to this embodiment, the spring member 24 elastically deforms to contact the male terminal portion 32, and therefore the contact state can be stabilized by absorbing component tolerances, etc.

[0026] As shown in FIG. 2, when the male terminal portion 32 is fully inserted into the female terminal portion 22, the bolt 4 penetrates the female housing 21 and is fastened to the nut portion 33 of the male housing 31. This connects the male inner connector 3 and the female inner connector 2 and firmly assembles them. In this way, the connector device 1 is made compact in size when the male inner connector 3 and the female inner connector 2 are connected. That is, as described above, the male inner connector 3 and the female inner connector 2 are each configured compactly because the clearance (gap) between the parts is reduced by the insert molding of the male housing 31 and the female housing 21. Therefore, the connector device 1 configured by connecting the male inner connector 3 and the female inner connector 2 is also made compact.

[0027] As described above, the connector device 1 according to this embodiment can be made compact by molding the female housing 21 integrally with the female terminal portion 22 and the male housing 31 integrally with the male terminal portion 32, thereby reducing the gap between the parts. Furthermore, the connector device 1 according to this embodiment can reduce the number of parts, making it easier to manage the parts.

[0028] In addition, the connector device 1 of this embodiment accommodates the spring member 24 in the female terminal portion 22 and brings the female terminal portion 22 and the male terminal portion 32 into contact with each other via the spring member 24, thereby stabilizing the connection between the female terminal portion 22 and the male terminal portion 32.

[0029] The connector device according to the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. The connector device 1 according to this embodiment may be configured by appropriately combining the components of the above-described embodiments and modified examples.

[0030] For example, the connector device 1 according to the above-described embodiment has been described as being used in an electric vehicle, but it may also be used in vehicles other than electric vehicles or in other devices. [Explanation of symbols]
