[0015] [Description of embodiments of this disclosure]

[0016] First, embodiments of this disclosure are listed and described.

[0017] [1] A connector device comprising: The device includes a first terminal, a first connector housing housing the first terminal, an electrical junction box on which the first connector housing is mounted, and a housing housing the first connector housing and the electrical junction box; and A connector having a second terminal connected to the first terminal via a connection hole formed in the housing, and a second connector housing for receiving the second terminal; One of the first terminal and the second terminal is the female terminal. The other of the first terminal and the second terminal is a male terminal. The first connector housing has a first housing body for receiving the first terminal, a first flange disposed on the outer periphery of the first housing body, and a first through hole passing through the first flange. The electrical junction box has a second through hole. The outer casing has a protrusion that inserts into the first through hole and the second through hole.

[0018] In the connector assembly described above, the second terminal of the connector is connected to the first terminal of the assembly. One of these first and second terminals is a female terminal, and the other is a male terminal. Therefore, the operator can easily connect the second terminal to the first terminal from outside the housing.

[0019] Furthermore, the protrusion of the outer casing inserts into the first through hole of the first connector housing and the second through hole of the electrical junction box. Therefore, the relative positional relationship between the first connector housing, the electrical junction box, and the outer casing can be determined.

[0020] [2] The connector device as described in [1], wherein, The first connector housing and the electrical junction box are fixed to the outer casing with bolts.

[0021] In a structure where the first connector housing and the electrical junction box are bolted to the outer casing, the following problems can be considered. When attempting to bolt the first connector housing and the electrical junction box relative to the outer casing in sequence, the component bolted first may interfere with the component to be bolted later, and the bolting position of the component to be bolted later may be offset from the bolting position of the outer casing.

[0022] However, in the aforementioned connector assembly, as described above, the relative positions of the first connector housing, the electrical junction box, and the outer casing are determined by the protrusion of the outer casing. Therefore, after determining these relative positions, the operator can bolt the first connector housing and the electrical junction box to the outer casing, thereby solving the aforementioned problem.

[0023] [3] The connector device as described in [1] or [2], wherein, The first terminal is fixed to the electrical junction box directly or via other components.

[0024] As described above, the relative positions of the first connector housing, the electrical junction box, and the outer casing are determined by the protrusion of the outer casing. Furthermore, the first terminal is fixed to the electrical junction box directly or via other components. In other words, according to the connector assembly described above, the relative positions of the first terminal with respect to the first connector housing and the outer casing can also be determined.

[0025] [4] The connector device as described in [3], wherein, The second connector housing is fixed to the outer shell using bolts.

[0026] As described above, the relative positional relationship between the first terminal and the housing can also be positioned according to the connector device described above. Therefore, according to the connector device described above, it is easy to avoid the bolt tightening position of the second connector housing shifting from the bolt tightening position of the housing after the second terminal is connected to the first terminal.

[0027] [Details of the embodiments disclosed herein]

[0028] 1. First Implementation Method

[0029] 1-1. Structure of the connector assembly

[0030] Figure 1 and Figure 2 The connector device 1 shown includes a device 10 and a connector 70. The device 10 is, for example, a battery pack mounted in 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 is referred to as the connection direction.

[0031] The device 10 has a first terminal 20, a first connector housing 30, an electrical junction box 40, a fixing component 50, and a housing 60.

[0032] The first terminal 20 is a female terminal. The first terminal 20 is conductive. The first terminal 20 is, for example, made of metal. The first terminal 20 is housed within the housing 60. The first terminal 20 is disposed toward the outside of the housing 60 via a connection hole 61 formed in the housing 60.

[0033] The first connector housing 30 houses the first terminal 20. The first connector housing 30 is insulating. The first connector housing 30 is, for example, made of resin. The first connector housing 30 has a first housing body 31 for housing the first terminal 20, a first flange 32 disposed on the outer periphery of the first housing body 31, and a first through hole 33 passing through the first flange 32. The first through hole 33 passes through the first flange 32 in the connection direction.

[0034] The electrical junction box 40 is insulated. The electrical junction box 40 is made of, for example, resin. The electrical junction box 40 has a mounting hole 41. A first connector housing 30 is mounted to the mounting hole 41. The electrical junction box 40 has a mounting wall 42 with the mounting hole 41. The electrical junction box 40 has a second through hole 43. The second through hole 43 is formed in the mounting wall 42. The second through hole 43 extends in the connection direction. The second through hole 43 is positioned to overlap with the first through hole 33 in the through direction.

[0035] The fixing member 50 secures the first terminal 20 to the electrical junction box 40. The fixing member 50 has a busbar 51 and an electrical component 52. The electrical component 52 is, for example, a relay, a fuse, etc. The fixing member 50 is fixed to the bottom wall portion 44 of the electrical junction box 40. The bottom wall portion 44 is located on the side of the electrical junction box 40 opposite to the mounting wall portion 42.

[0036] The housing 60 is insulating. The housing 60 is, for example, made of 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 the housing-side mounting wall 62 of the housing 60. The housing-side mounting wall 62 is disposed opposite to the mounting wall 42 of the electrical junction box 40. The housing 60 has a protrusion 63. The protrusion 63 is provided in the housing-side mounting wall 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.

[0037] The first connector housing 30 and the electrical junction box 40 are secured to the outer casing 60 using bolts 80. Specifically, a plurality of bolt fastening portions 64 are provided on the outer casing side mounting wall 62 of the outer casing 60. Bolt insertion holes 81 are formed on the first flange 32 of the first connector housing 30 and the mounting wall 42 of the electrical junction box 40 at positions corresponding to at least one bolt fastening portion 64. Figure 1 and Figure 2 In the example shown, the bolt insertion hole 81 of the first connector housing 30 is positioned to overlap with the bolt insertion hole 81 of the electrical junction box 40 in the through direction. However, the bolt insertion hole 81 of the first connector housing 30 may also be positioned to not overlap with the bolt insertion hole 81 of the electrical junction box 40 in the through direction. The first connector housing 30 and the electrical junction box 40 are fixed to the outer casing 60 by inserting bolts 80 into the bolt insertion holes 81 and fastening them to the bolt fastening portion 64.

[0038] 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 metal, for example. The second connector housing 72 houses the second terminal 71. The second connector housing 72 is insulating. The second connector housing 72 is made of resin, for example. The second connector housing 72 has a second housing body 73 that houses the second terminal 71, and a second flange 74 disposed on the outer periphery of the second housing body 73.

[0039] The second connector housing 72 is secured to the outer casing 60 using bolts 80. Specifically, a plurality of bolt fastening portions 65 are provided on the outer casing side mounting wall 62 of the outer casing 60. Bolt insertion holes 82 are formed on 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 secured to the outer casing 60 by inserting bolts 80 into the bolt insertion holes 82 and tightening them to the bolt fastening portions 65.

[0040] 1-2. Effects

[0041] In connector device 1, the second terminal 71 of connector 70 is connected to the first terminal 20 provided in device 10. The first terminal 20 is a female terminal, and the second terminal 71 is a male terminal. Therefore, the operator can easily connect the second terminal 71 to the first terminal 20 from outside the housing 60.

[0042] Furthermore, the protrusion 63 of the outer casing 60 is inserted into the first through hole 33 of the first connector housing 30 and the second through hole 43 of the electrical junction box 40. Therefore, the relative positional relationship between the first connector housing 30, the electrical junction box 40, and the outer casing 60 can be determined.

[0043] In a structure where the first connector housing 30 and the electrical junction box 40 are fixed to the outer casing 60 using bolts 80, the following problem can be considered. When attempting to sequentially bolt the first connector housing 30 and the electrical junction box 40 relative to the outer casing 60, the component bolted first may interfere with the component to be bolted later, and the bolting position of the component to be bolted later (specifically, the bolt insertion hole 81) may shift from the bolting position of the outer casing 60 (specifically, the bolt fastening part 64).

[0044] However, in the connector assembly 1, as described above, the relative positions of the first connector housing 30, the electrical junction box 40, and the housing 60 are determined by the protrusion 63 of the housing 60. Therefore, after determining these relative positions, the operator can bolt the first connector housing 30 and the electrical junction box 40 to the housing 60, thereby solving the aforementioned problem.

[0045] As described above, the relative positions of the first connector housing 30, the electrical junction box 40, and the outer casing 60 are positioned by the protrusion 63 of the outer casing 60. Furthermore, the first terminal 20 is fixed to the electrical junction box 40 via the fixing member 50. In other words, according to the connector device 1, the relative positions of the first terminal 20 with the first connector housing 30 and the outer casing 60 can also be positioned.

[0046] As described above, according to the connector device 1, the relative positional relationship between the first terminal 20 and the housing 60 can also be positioned. Therefore, according to the connector device 1, it is easy to prevent the bolt fastening position (specifically, the bolt insertion hole 82) of the second connector housing 72 from shifting from the bolt fastening position (specifically, the bolt fastening part 65) of the housing 60 after the second terminal 71 is connected to the first terminal 20.
