Description

Power supply box

Technical Field

The utility model relates to an electrical equipment technical field, concretely relates to power pack.

Background

The power box is usually connected between the electric equipment and the commercial power to convert the commercial power voltage into a voltage meeting the requirement of the electric equipment. However, the conventional power supply box output socket does not seal the contact pin therein, and after long-time use, external dust and the like easily enter the socket and fall on the contact pin, so that the contact stability is influenced.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide a power pack with a good dustproof effect.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a power pack, its characterized in that: the novel contact pin mounting structure comprises a housin, be provided with contact pin in the casing, the casing is provided with the socket in the position department relative with contact pin, the socket below is provided with the guiding hole, the guiding hole upper end sets up the brush, be provided with the mounting panel between contact pin and the guiding hole, be provided with the opening that corresponds with the guiding hole position on the mounting panel, be provided with the mounting groove with the opening intercommunication on the mounting panel, be provided with the baffle in the mounting groove, the baffle is provided with the spring towards keeping away from between the tank bottom of open-ended one side and mounting groove, the baffle is provided with the direction inclined plane towards the guiding hole towards open-ended one side.

Further, an elastic layer is arranged at the end part of one side, facing the opening, of the baffle.

Furthermore, the shell comprises a bottom plate and an upper shell detachably connected with the bottom plate.

Further, the elastic layer is made of a rubber material.

Compared with the prior art, the utility model has the advantages of it is following: by arranging the baffles, when the external plug is not inserted into the socket, the two baffles are abutted to seal the lower end of the guide hole to prevent external dust and the like from entering the socket and falling on the contact pin, and when the pin of the external plug is inserted into the socket, the pin of the external plug applies force towards two sides to the baffles to separate the two baffles, so that the pin of the external plug can be inserted, and when the external plug is pulled out, the two baffles are restored to be abutted to prevent the external dust from entering; the brush is arranged, so that the contact pin of the external plug can be cleaned to a certain degree, and the contact stability is prevented from being influenced by the contact pin; noise when the plug inserts can be reduced through setting up the elastic layer, increases the operation comfort.

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.

In the description of the present invention, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the terms of orientation and positional relationship indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.

Fig. 1 to 2 show that this kind of power pack is shown as a structural schematic diagram of the preferred embodiment of this application, and as shown in the figure, this kind of power pack includes casing 1, be provided with contact pin 2 in the casing 1, casing 1 is provided with socket 31 in the position department relative with contact pin 2, socket 31 below is provided with guiding hole 32, guiding hole 32 upper end sets up brush 33, be provided with mounting panel 34 between contact pin 2 and the guiding hole 32, be provided with opening 341 corresponding with guiding hole 32 position on the mounting panel 34, be provided with mounting groove 342 with opening 341 intercommunication on the mounting panel 34, be provided with baffle 35 in the mounting groove 342, be provided with spring 36 between one side of baffle 35 towards keeping away from opening 341 and the tank bottom of mounting groove 342, one side of baffle 35 towards opening 341 is provided with the direction inclined plane towards guiding hole 32. When external plug (not shown in the figure) does not insert socket 31, under the effect of spring 36, two baffles 35 offset, can seal guiding hole 32 lower extreme and prevent that outside dust etc. from falling on contact pin 2 in getting into socket 31, and when the contact pin of external plug inserted socket 31, the contact pin of external plug applys the power towards both sides to baffle 35 and makes two baffles 35 separately, thereby make the contact pin of external plug insert, when extracting the external plug, two baffles 35 resume the state of offsetting and prevent that outside dust from getting into, and through setting up brush 33, can carry out the cleanness of certain degree to the contact pin of external plug, thereby make this power pack have fine dustproof effect.

In order to prevent the occurrence of a harsh noise between the shutter 35 and the external plug when the external plug is inserted, an elastic layer 37 is provided on an end portion of the shutter 35 facing the opening, and specifically, the elastic layer 37 is made of a rubber material.

In this embodiment, the housing 1 includes a bottom plate 11 and an upper shell 12 detachably connected to the bottom plate 11, and the bottom plate 11 and the upper shell 12 are connected by screws or fasteners.

Of course, it should be noted that the power supply box may further include other structures, such as a mounting seat for mounting the contact pins, and the like, which are not described in detail herein since they are not within the scope of the present application.

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.
