Referring to fig. 1 to 3, the present invention provides a power supply 1, which includes a housing 11, a battery cell 12, a cover plate 13, a glue sealing groove 14, and a waterproof rubber ring 15.

The housing 11 and the cover plate 13 are connected to form a receiving space, and the battery cell 12 or a circuit board (not shown) inside the power supply 1 is disposed in the receiving space. For example, the battery cell 12 is disposed on a circuit board having a management module of the power supply 1, and both the battery cell 12 and the circuit board are located in the accommodating space.

The battery cell 12 may be connected to the housing 11 by a clamping structure or a screw connection.

The glue sealing groove 14 is formed in the position where the shell 11 and the cover plate 13 are combined, so that after the shell 11 and the cover plate 13 are connected together, waterproof glue is filled in the glue sealing groove 14 to seal a combination gap between the shell 11 and the cover plate 13, and the accommodating space enclosed by the shell 11 and the cover plate 13 is a closed space, so that the purpose of preventing water outside the power supply 1 from entering the power supply 1 from the combination gap between the shell 11 and the cover plate 13 is achieved, and the battery cell 12 is protected.

As shown in fig. 1 and 2 in combination, the edge portion of the cover 13 has a recess 14a, so that when the cover 13 is assembled to the housing 11, the recess 14a and the inner wall of the housing 11 define a sealant groove 14. Since the recessed portion 14a is located at the edge of the cover plate 13, when the waterproof adhesive is injected into the adhesive sealing groove 14, the waterproof adhesive can cover the gap between the cover plate 13 and the inner wall of the housing 11 from the edge of the cover plate 13, and a good sealing effect can be achieved.

With reference to fig. 5 to 7, the waterproof rubber ring 15 is configured to be disposed at the electrical connection port of the power source 1, so that when the electrical connection port of the power source 1 is matched with the connection terminal of the electrical equipment 2, the waterproof rubber ring 15 realizes waterproofing between the electrical connection port of the power source 1 and the connection terminal of the electrical equipment 2.

For the convenience of understanding, the waterproof rubber ring 15 is further described below only by taking the electric device 2 shown in fig. 5 to 7 as an example to achieve waterproofing between the electric connection port of the power source 1 and the connection terminal of the electric device 2.

The electric equipment 2 includes a housing 21 and an electronic circuit board 22. The housing 21 is provided with sockets, and the number of the sockets may be 1, or 2 or more than 2. Specifically, the number and the positions of the arrangement of the jacks correspond to the connection terminals of the electronic circuit board 22. For example, referring to fig. 7, the electronic circuit board 22 is provided with 2 connection terminals, which may be an ac terminal 221 and a dc terminal 222, respectively. Accordingly, the housing 21 is provided with a first socket 211 and a second socket 212 for exposing the ac terminal 221 and the dc terminal 222, respectively, so that the electrical connection port of the power source 1 and the connection terminal of the electric device 2 can be electrically connected to each other.

The matching between the power source 1 and the electrical equipment 2 will be further explained by taking an example that the power source 1 is provided with 2 electrical connection ports which are respectively butted with 2 connection terminals of the electrical equipment 2. For convenience of description, the 2 electrical connection ports of the power supply 1 are referred to as a "first electrical connection port 121" and a "second electrical connection port 122", respectively, as shown in fig. 5.
