Connector device.

[0011] In the connector device, a second terminal of the connector is connected to a first terminal provided on the device. One of the first terminal and the second terminal is a female terminal, and the other is a male terminal. This allows an operator to easily connect the second terminal to the first terminal from outside the housing. Furthermore, the protrusion of the housing is inserted into the first through hole of the first connector housing and the second through hole of the electrical junction box, so that the relative positions of the first connector housing, the electrical junction box, and the housing can be determined.

[0012] [2] The first connector housing and the electrical junction box are fixed to the housing using bolts. The connector device described in [1].

[0013] In a configuration in which the first connector housing and the electrical junction box are fixed to the housing with bolts, the following problem is anticipated: When attempting to bolt the first connector housing and the electrical junction box to the housing in that order, the component bolted first may interfere with the component to be bolted later, causing the bolt fastening position of the component to be bolted later to deviate from the bolt fastening position of the housing. However, in the above connector device, as described above, the relative positions of the first connector housing, the electrical junction box, and the housing are determined by the protrusion of the housing, so the worker can resolve the above problem by determining the relative positions of these components and then fastening the first connector housing and the electrical junction box to the housing with bolts.

[0014] [3] The first terminal is fixed to the electrical junction box directly or via a separate member. A connector device according to [1] or [2].

[0015] As described above, the protrusion of the housing determines the relative positions of the first connector housing, the electrical junction box, and the housing. Furthermore, the first terminal is fixed to the electrical junction box directly or via a separate member. In other words, the connector device can also determine the relative positions of the first terminal, the first connector housing, and the housing.

[0016] [4] The second connector housing is fixed to the housing using bolts. The connector device described in [3].

[0017] As described above, the connector device can also determine the relative positional relationship between the first terminals and the housing, which makes it easier to prevent misalignment of the bolt fastening positions of the second connector housing and the bolt fastening positions of the housing after connecting the second terminals to the first terminals.

[0018] [Details of the embodiments of the present disclosure] 1. First embodiment 1-1. Connector device configuration The connector device 1 shown in Figures 1 and 2 includes a device 10 and a connector 70. The device 10 is, for example, a battery pack mounted on a vehicle. The connector 70 is connected to the device 10. Hereinafter, the direction in which the connector 70 is connected to the device 10 will be referred to as the connection direction.

[0019] The device 10 includes a first terminal 20, a first connector housing 30, an electric junction box 40, a fixing member 50, and a housing 60.

[0020] The first terminal 20 is a female terminal. The first terminal 20 is conductive. The first terminal 20 is made of, for example, metal. The first terminal 20 is housed in a housing 60. The first terminal 20 is arranged facing the outside of the housing 60 through a connection hole 61 formed in the housing 60.

[0021] The first connector housing 30 accommodates the first terminals 20. The first connector housing 30 has insulating properties. The first connector housing 30 is made of, for example, resin. The first connector housing 30 has a first housing main body 31 that accommodates the first terminals 20, a first flange 32 provided on the outer periphery of the first housing main body 31, and a first through hole 33 that penetrates the first flange 32. The first through hole 33 penetrates the first flange 32 in the connection direction.

[0022] The electrical junction box 40 has insulating properties. The electrical junction box 40 is made of, for example, resin. The electrical junction box 40 has a mounting hole portion 41. The first connector housing 30 is attached to the mounting hole portion 41. The electrical junction box 40 has a mounting wall portion 42 in which the mounting hole portion 41 is provided. The electrical junction box 40 has a second through hole 43. The second through hole 43 is formed in the mounting wall portion 42. The second through hole 43 penetrates in the connection direction. The second through hole 43 is positioned at a position overlapping with the first through hole 33 in the penetration direction.

[0023] The fixing member 50 fixes the first terminal 20 to the electrical junction box 40. The fixing member 50 has a bus bar 51 and an electrical component 52. The electrical component 52 is, for example, a relay or a fuse. The fixing member 50 is fixed to the bottom wall portion 44 of the electrical junction box 40. The bottom wall portion 44 is provided on the opposite side of the electrical junction box 40 from the mounting wall portion 42.

[0024] The housing 60 has insulating properties. The housing 60 is made of, for example, resin. The housing 60 houses the first connector housing 30 and the electrical junction box 40. The housing 60 has a connection hole 61. The connection hole 61 is formed in a housing-side mounting wall portion 62 of the housing 60. The housing-side mounting wall portion 62 is arranged opposite the mounting wall portion 42 of the electrical junction box 40. The housing 60 has a protrusion 63. The protrusion 63 is provided on the housing-side mounting wall portion 62. The protrusion 63 is configured to protrude toward the inside of the housing 60. The protrusion 63 is inserted into the first through hole 33 and the second through hole 43.

[0025] The first connector housing 30 and the electrical junction box 40 are fixed to the housing 60 using bolts 80. Specifically, a housing-side mounting wall 62 of the housing 60 is provided with a plurality of bolt fastening portions 64. A bolt insertion hole 81 is formed in the first flange 32 of the first connector housing 30 and the mounting wall 42 of the electrical junction box 40 at a position corresponding to at least one of the bolt fastening portions 64. In the example shown in FIGS. 1 and 2 , the bolt insertion hole 81 of the first connector housing 30 is arranged at a position overlapping with the bolt insertion hole 81 of the electrical junction box 40 in the penetration direction. However, the bolt insertion hole 81 of the first connector housing 30 may be arranged at a position not overlapping with the bolt insertion hole 81 of the electrical junction box 40 in the penetration direction. The first connector housing 30 and the electrical junction box 40 are fixed to the housing 60 by inserting the bolts 80 into the bolt insertion holes 81 and fastening them to the bolt fastening portions 64.

[0026] The connector 70 has a second terminal 71 and a second connector housing 72. The second terminal 71 is a male terminal. The second terminal 71 is connected to the first terminal 20 through a connection hole 61 formed in the housing 60. The second terminal 71 is conductive. The second terminal 71 is made of, for example, metal. The second connector housing 72 accommodates the second terminal 71. The second connector housing 72 is insulating. The second connector housing 72 is made of, for example, resin. The second connector housing 72 has a second housing main body 73 that accommodates the second terminal 71, and a second flange 74 provided on the outer periphery of the second housing main body 73.

[0027] The second connector housing 72 is fixed to the housing 60 using bolts 80. Specifically, a plurality of bolt fastening portions 65 are provided on the housing-side mounting wall portion 62 of the housing 60. Bolt insertion holes 82 are formed in the second flange 74 of the second connector housing 72 at positions corresponding to the bolt fastening portions 65. The second connector housing 72 is fixed to the housing 60 by inserting the bolts 80 into the bolt insertion holes 82 and fastening them to the bolt fastening portions 65.

[0028] 1-2.Effects In the connector device 1, a second terminal 71 of the connector 70 is connected to a first terminal 20 provided in the device 10. The first terminal 20 is a female terminal, and the second terminal 71 is a male terminal. Therefore, an operator can easily connect the second terminal 71 to the first terminal 20 from outside the housing 60.

[0029] Moreover, the protrusion 63 of the housing 60 is inserted into the first through-hole 33 of the first connector housing 30 and the second through-hole 43 of the electric junction box 40. Therefore, the relative positional relationship between the first connector housing 30, the electric junction box 40, and the housing 60 can be determined.

[0030] In a configuration in which the first connector housing 30 and the electrical junction box 40 are fixed to the housing 60 using bolts 80, the following problem is anticipated: When attempting to bolt the first connector housing 30 and the electrical junction box 40 to the housing 60 in that order, the component fastened with the bolts first may interfere with the component to be bolted later, and the bolt fastening position of the component to be bolted later (specifically, bolt insertion hole 81) may be misaligned from the bolt fastening position of the housing 60 (specifically, bolt fastening portion 64).

[0031] However, in the connector device 1, as described above, the relative positional relationship between the first connector housing 30, the electric junction box 40, and the housing 60 is determined by the protrusion 63 of the housing 60. Therefore, the worker can solve the above problem by determining the relative positional relationship between these elements and then fastening the first connector housing 30 and the electric junction box 40 to the housing 60 with bolts.

[0032] As described above, the protrusion 63 of the housing 60 determines the relative positional relationship between the first connector housing 30, the electric junction box 40, and the housing 60. Furthermore, the first terminal 20 is fixed to the electric junction box 40 via the fixing member 50. In other words, according to the connector device 1, the relative positional relationship between the first terminal 20, the first connector housing 30, and the housing 60 can also be determined.

[0033] As described above, according to the connector device 1, it is possible to determine the relative positional relationship between the first terminals 20 and the housing 60. Therefore, according to the connector device 1, after the second terminals 71 are connected to the first terminals 20, it is easy to prevent the bolt fastening positions of the second connector housing 72 (specifically, the bolt insertion holes 82) from being misaligned with the bolt fastening positions of the housing 60 (specifically, the bolt fastening portions 65).
