Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in fig. 1 to 4, the waterproof PDU includes a housing 100, and a PDU common substrate 6 installed in the housing 100.

The casing 1 is preferably rectangular, and the whole outer surface of the casing 1 is provided with an antirust layer 7. The panels constituting the housing 1 include a mounting panel 1 for mounting a plurality of rotatable rotary jack sockets 2. For convenience of description, the direction of the inside of the housing 1 toward the outside of the housing through the mounting panel is defined as front, and the direction of the outside of the housing toward the inside of the housing through the mounting panel is defined as rear. On the outer surface of the installation panel, the peripheral part of each rotary jack seat 2 is provided with a circular ring-shaped sealing embedded groove 3.

For the rotary jack socket which is not connected with the external plug temporarily on the installation panel 1, as shown in three rotary jack sockets on the right side in fig. 2, the peripheral sealing embedding groove 3 is matched and connected with the external sealing cap 10. When sealing, be equipped with on the sealed cap 10 and inlay the first ring shape opening 10a that the groove 3 matches with sealed, this first ring shape opening is closely connected with the sealed groove 3 of inlaying of ring shape, realizes this rotatory jack socket to the isolation of external environment.

For the installation panel 1, a rotary jack for connecting an external plug is required, as shown in the left two rotary jacks in fig. 2, and a sealing embedding groove 3 at the periphery is matched and connected with the external plug. Similarly, the external plug is also provided with a second annular opening (not shown in the figure) matched with the sealing embedding groove 3 at the periphery of the plug, and the second annular opening is tightly matched and connected with the annular sealing embedding groove 3, so that the plug and the rotary jack socket are isolated from the external environment.

The PDU common substrate 6 is mounted inside the housing 100 in any known manner, including components such as a printed circuit board with power supply lines. The PDU generic substrate belongs to the prior art and is not described in detail herein.

The bus 5 connected to the PDU universal board 6 is extended from any panel (e.g., a side panel) of the housing 100 to be connected to an external bus plug.

Inside the housing 100, the rear part of the rotary jack 2 is connected to the PDU common substrate by a number of wires 8.

In this embodiment, each rotary jack 2 further includes a two-phase jack and a three-phase jack, so 5 wires are connected between each rotary jack 2 and the PDU universal substrate. The wires 8 at the rear of each rotary jack seat 2 are restrained by the collecting coil 12, and the wires 8 are prevented from being dispersed too much.

The rotary jack 2 is rotatably mounted on the front panel of the housing 1 in any known manner. A preferred mounting is provided. The mounting panel 1 of the housing 100 is provided with a circular through hole 1a, on the inner side wall of which is provided an annular groove 9 radially outward, and the rotary jack 2 is substantially cylindrical and provided on the side surface thereof with an annular column 11 radially outward projecting. When connected, the annular column 11 is clamped in the annular groove 1 a. Thereby achieving free rotation of the rotary socket 2 within the annular through hole 1 of the housing 100. Of course, to facilitate the installation of the annular post 11 in the annular groove 9, the annular groove 9 is of a split mountable construction.

Preferably, the front portion of the cylindrical side wall of the annular groove 9 is provided with a first stopper 13 (not shown in fig. 3, shown in fig. 4) projecting radially inwards, and the front wall of the annular column 11 is provided with a second stopper 14 (not shown in fig. 3, shown in fig. 4). The first stopper 13 positionally restrains the annular column 11 (i.e., the rotary jack 2) from the front-rear direction. Further, the distance from the first stopper 13 to the axis of the circular through hole 1a is the same as the distance from the second stopper 14 to the axis of the circular through hole 1a, and the positions of both stoppers in the front-rear direction are the same. When the rotary jack seat 2 rotates relative to the front panel of the shell 1, if the rotation angle is too large, the first limit block 13 and the second limit block 14 are abutted, so that further rotation is prevented. Therefore, the rotary socket 2 can rotate only about ± 180 ° relative to the housing 100 in the position shown in fig. 4, so as to avoid the lead 8 connected to the rear portion from being structurally detached due to over-screwing.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
