The holding portion 82 is provided with a holding hole 82a into which the locking protrusion 31b is inserted. Therefore, when the inner lid 8 is attached to the inner body 3 and the accommodation space 31a is closed by the inner lid 8, the locking protrusion 31b is inserted and engaged into the holding portion 82a so that the state in which the inner lid 8 is attached to the inner body 3 is maintained.

A sealing member 9 is disposed between the inner body 3 and the inner lid 8 to prevent moisture from penetrating into the receiving space 31 a.

A plurality of fuse members 7 for preventing transmission of overcurrent and a plurality of terminals 4, 5 and 6 for distributing power supplied to the power connector to a plurality of devices are received in the inner body 3.

The plurality of fuse members 7 are each formed as a cylindrical fuse member shaped in a substantially cylindrical shape.

The plurality of terminals 4, 5, and 6 are made of an elastically deformable conductive material. The terminals 4, 5, and 6 may be formed by bending a metal plate.

As shown in fig. 5 and 6, one end of the first cable W1 connected to the power supply is connected to the terminals 4, 5 and 6, and the terminals 4, 5 and 6 include a first terminal 4, an intermediate terminal 5 and a plurality of second terminals 6, the first terminal 4 including a plurality of terminal portions 42 for supplying power, the intermediate terminal 5 being connected to one end of the second cable W2 (the second cable W2 being connected to the power supply) and including a plurality of first clips 52 respectively connected to first end portions of a plurality of fuse members 7, each of the plurality of second terminals 6 including a second clip 61 and a second terminal portion 62, the second clip 61 connecting a second end portion of a corresponding one of the plurality of fuse members 7, the second terminal portion 62 being for supplying power.

The first terminal 4 includes a first connecting portion 41 connected to the first cable W1 and two first terminal portions 42 extending from opposite sides of the first connecting portion 41.

The intermediate terminal 5 includes a second connection portion 51 connecting one end of the second cable W2 and two first clips 52 mounted on opposite sides of the second connection portion 51.

Two second terminals 6 are provided, and each includes one second clip 61 and one second terminal portion 62. That is, the power connector may include two second terminal portions 62.

Each of the first clips 52 includes a pair of grip portions 52a, and each of the second clips 61 includes a pair of grip portions 61a, the grip portions 52a and the grip portions 61a being formed in an arc shape corresponding to the cylindrical fuse member 7, and the guide portions 52b extend outward from one ends of the pair of mutually spaced grip portions 52a, and the guide portions 61b extend outward from one ends of the pair of mutually spaced grip portions 61 a.

The pair of grip portions 52a and 61a are spaced apart from each other such that inner peripheral surfaces thereof face each other, and each fuse member 7 is accommodated between the pair of grip portions 52a and 61 a. The guide portions 52b and 61b guide the fuse member 7 to easily enter between the pair of clamping portions 52a and 61 a.

Since the terminals 4, 5, and 6 are made of an elastically deformable material, the pair of grip portions 52a and 61a are temporarily elastically deformed outward in the process that the fuse member 7 is guided by the guide portions 52b and 61b and enters between the pair of grip portions 52a and 61 a. After the fuse member 7 enters between the pair of clamping portions 52a and 61a, the pair of clamping portions 52a and 61a elastically recover to support the fuse member 7 and thus connect to the fuse member 7.

Referring to fig. 4 to 7, the first cable W1 and the second cable W2 include annular wire harnesses Wa1 and Wa2, respectively, provided at one ends thereof. The wire harnesses Wa1 and Wa2 are formed such that one ends of the first cable W1 and the second cable W2 are fixed to the first connecting portion 41 and the second connecting portion 51 by a bolt S and a nut N, respectively. Here, the nut N is a square nut, and the inner body 3 includes a square groove in which the square nut N can be disposed.

Referring to fig. 3 and 8, the inner lid 8 includes support ribs 83, and the support ribs 83 support the first and second clips 52 and 61 by protruding into the receiving space 31a in a state where the inner lid 8 is mounted in the inner body 3.

Support ribs 83 protrude from the inner surface of the inner lid 8, and the support ribs 83 are configured to prevent the clamping portions 52a and 61a from being deformed outward by supporting opposite sides of the first clip 52 and opposite sides of the second clip 61.

In an exemplary embodiment of the present invention, since the power connector includes two first clips 52 and two second clips 61, the support rib 83 includes two pairs to support the outer sides of the two first clips 52 and the two second clips 61.

The inner lid 8 includes a pressing rib 84 provided between two support ribs 83 formed as a pair. The pressing rib 84 is configured to more reliably prevent the clamping portions 52a and 61a from being deformed by pressing the upper end of the guide portion 52b of the first clip 52 and the upper end of the guide portion 61b of the second clip 61.

Two pressing ribs 84 are provided between the pair of support ribs 83 to support the guide portion 52b of the first clip 52 and the guide portion 61b of the second clip 61. In the exemplary embodiment of the present invention, since the support ribs 83 include two pairs, the inner lid 8 includes four pressing ribs 84 in total.

Although the crush rib 84 is referred to as being disposed between the pair of support ribs 83, the present invention is not limited thereto. As shown in fig. 9, the pressing rib 85 may be provided to support the outer surfaces of the clamping portions 52a and 61a by protruding from the mutually facing surfaces of the pair of support ribs 83.

As described above, since the two grip portions 52a and 61a are provided for each of the two first clips 52 and the two second clips 61, the inner cover 8 supporting the grip portions 52a and 61a includes eight pressing ribs 85 in total.

Although the first clip 52 and the second clip 61 are each referred to as being two in number, the present invention is not limited thereto.

For example, as shown in fig. 10, three first clips 52 and three second clips 61 may be provided so that electric power is distributed to three devices, or as shown in fig. 11, four first clips 52 and four second clips 61 may be provided so that electric power is distributed to four devices.

As is apparent from the above, the power connector according to aspects of the present invention may include a plurality of connector parts so that power can be distributed to a plurality of power-using devices.

Further, according to the power supply connector of the various aspects of the present invention, the support ribs of the inner cover support the opposite sides of the clamping portion in a state where the inner cover closes the accommodation space, so that a state where the fuse member is arranged on the clamping portion can be stably maintained.
