According to a first aspect of an embodiment of the present utility model, there is provided a housing, the structure of which will be described in detail below with reference to fig. 1 to 6.

In an embodiment, the housing includes a main body 10, a plurality of first engaging portions 20, and a plurality of second engaging portions 30. Wherein the main body 10 includes a cavity 11, and a plurality of first engaging portions 20 are disposed in the cavity 11, each first engaging portion 20 is configured to be detachably connected to a corresponding electrical component, and each first engaging portion 20 includes a first mounting surface 21 engaged with the corresponding electrical component. A plurality of second engaging portions 30 are provided on the outside of the main body 10, each second engaging portion 30 being for detachably connecting with a corresponding connector, each second engaging portion 30 including a second mounting surface 31 engaged with the corresponding connector.

According to the housing provided in the first aspect of the embodiment of the present utility model, the first engaging portion 20 is provided, the first engaging portion 20 having the first mounting surface 21 is used to detachably connect with the electrical component, and the second engaging portion 30 is provided, and the second engaging portion 30 having the second mounting surface 31 is used to detachably connect with the connector, whereby the housing provided in the first aspect of the embodiment of the present utility model can realize stable pre-assembly of the electrical component and the connector to the housing, thereby making the assembly of the integrated power distribution module using the housing simple, improving the assembly efficiency, and enabling convenient and quick assembly.

In addition, according to the housing provided in the first aspect of the embodiment of the present utility model, since the electrical component and the connector are detachably connected, during the pre-assembly process, the type and the relative position of the electrical component are convenient to be adjusted, so as to ensure that the electrical component and the connector have a better post-assembly state.

As such, according to the housing provided in the first aspect of the embodiment of the present utility model, since each first joint 20 protrudes from the inner wall of the cavity 11 into the cavity 11, the first joint 20 occupies the space in the cavity 11, thereby converting the arrangement space required for the first joint 20, which may be borne by the main body 10 of the housing, into the cavity 11, allowing the inner wall of the cavity 11 to be made thinner, thereby contributing to the reduction of the overall weight of the housing. In addition, the first joint part 20 protruding into the cavity 11 has a certain structural strength, which is beneficial to realizing the stability of supporting the electronic component.

Similarly, the advantages of the arrangement of the second engaging portion 30 are the same as those of the arrangement of the first engaging portion 20, and also allow the inner wall of the cavity 11 of the housing provided according to the first aspect of the embodiment of the present utility model, that is, the main body 10, to have a thinner thickness. At the same time, the protruding second engagement portion 30 can also provide a certain structural strength, which is advantageous for achieving stable support of the docking station.

In the embodiment, as an example, the first engaging portions 20 may protrude from the bottom of the housing into the cavity 11, which is advantageous in setting and unifying the relative positional relationship of the plurality of first engaging portions 20. As an example, in an embodiment, some of the first engaging portions 20 may be further connected with the inner side wall of the cavity 11 of the housing, thereby further improving the strength of the first engaging portions 20 and thus the stability of the support of the electrical component.

In an embodiment, according to the housing provided in the first aspect of the embodiment of the present utility model, each first engaging portion 20 may further include a first positioning portion 211 disposed on the first mounting surface 21, the first positioning portion 211 may be recessed with respect to the first mounting surface 21, and the first positioning portion 211 may be used to position a corresponding electrical component.

As such, the housing provided according to the first aspect of the embodiment of the utility model utilizes the first positioning portion 211 that can be recessed with respect to the first mounting surface 21 to position the electrical component, i.e., after the first mounting surface 21 abuts against the corresponding position of the electrical component to preliminarily position the electrical component, the positioning of the electrical component is completed by the first positioning portion 211, thereby ensuring that the electrical component is stably connected to the first joint portion 20, that is, to the housing.

As an example, the second mounting surface 31 may be formed with the insertion portion 311 and the second positioning portion 32 recessed with respect to the second mounting surface 31. Wherein the plugging portion 311 may be used to mate with a portion of the connector corresponding to the second engaging portion 30, in other words, a portion of the connector is inserted into the plugging portion 311, during which the connector is further positioned by the plugging portion 311, and then, on the basis of this, the connector is directly connected to the connector by the second positioning portion 32, and the connector is positioned again.

In an embodiment, the second positioning portion 32 may be a hole portion. Specifically, the hole portion may be, for example, but not limited to, a threaded hole, that is, the second engaging portion 30 may be detachably connected to the connector by means of a threaded connection, and during the connection, the connector is connected to the second engaging portion 30 by means of a screw after a through hole formed in the connector in advance corresponds to the threaded hole of the second engaging portion 30. As mentioned in the above description, this detachable form of threaded connection is reliable in connection, low in cost and easy to detach.

In addition, in other examples, similarly, the second positioning portion 32 may be a hole portion, the connector may be provided with a corresponding through hole, and the member for connecting the second engaging portion 30 and the connector may be a bolt-like fastener having elasticity, and the connector may be positioned in an "interference" manner by being inserted into the through holes of the second positioning portion 32 and the connector.

Furthermore, in the embodiment, a part of the second joint parts 30 of the plurality of second joint parts 30 may be used for the installation of the high-voltage connector, and another part of the second joint parts 30 may be used for the installation of the low-voltage connector, and for convenience of distinction, the second joint parts 30 having the high-voltage plug parts 312 and the second joint parts 30 having the low-voltage plug parts 313 are further marked in fig. 1.
