Description

waterproof power supply

technical field

The utility model relates to the technical field of communication electronics, in particular to a waterproof power supply.

Background technique

As an electronic product, a power supply is usually required to connect the mains, and the power supply is provided with a working circuit and a protection circuit. In order to ensure the normal operation of the power supply, the usual power supply requires a good heat dissipation effect to dissipate the heat in the power supply in time.

For a power supply that works outdoors, it must not only ensure a good heat dissipation effect, but also need to have a waterproof effect to prevent outdoor rainwater from entering the power supply, causing a short circuit of the power supply, and burning the power supply. Taking the outdoor street lamp power supply as an example, the current structural method is as follows: the circuit board of the power supply is installed in a box, and then silica gel is poured into the box, so that the circuit board and the box form a whole. Although this method can achieve the effects of waterproofing and heat dissipation, it also has the following disadvantages:

1. The cost is high. Due to the high price of silica gel raw materials, pouring silica gel into the power supply can have a good heat dissipation effect, but it also leads to high product costs.

2. Difficult to repair, because the circuit board is encapsulated in the power supply box through silica gel, the box body and the circuit board form a whole that cannot be disassembled. If there is a problem with the circuit in the circuit board, it cannot be repaired at all, and the entire power supply can only be scrapped , which causes huge waste and is not conducive to environmental protection.

3. The production process is complicated. Because the current production method needs to be filled with silica gel, the production process is increased and the production efficiency is reduced.

To sum up, manufacturers urgently need to design a new type of outdoor waterproof power supply that can overcome the shortcomings of the above products.

Utility model content

In order to overcome the above-mentioned disadvantages in the prior art, the purpose of this utility model is to provide a waterproof power supply with novel structure design and convenient use.

The utility model is realized through the following technical solutions: a waterproof power supply, including a power supply box composed of a box body and a box cover, the box body and the box cover are connected by screws, a circuit board is arranged in the power supply box, and a circuit board is arranged at one end of the box body There are positive and negative connectors connected with the circuit board and a power switch key. The contact surface between the box body and the box cover is provided with a waterproof sealing groove, and a waterproof sealing ring is embedded in the waterproof sealing groove.

Compared with the prior art, the utility model has the following advantages and beneficial effects: a waterproof sealing ring is added to the box body and the box cover of the utility model to improve the waterproof function of the circuit board in the box body. After adopting this structure, the product can be disassembled , easy to replace parts and components, and reduce product scrapping due to minor problems.
