Description

power regulator cover

【Technical field】

The utility model relates to a protective cover for a power regulator.

【Background technique】

In order to avoid excessive load under long-term operation, a power regulator is installed inside the instrument or inside the machine. The power regulator is mainly equipped with a silicon-controlled rectifier and connected to a temperature controller (thermometer), which can be controlled by temperature. When the operating temperature reaches the set value, the silicon controlled rectifier inside the power regulator can be used to adjust the operating current of the instrument or machine with a specific control circuit to avoid Or the temperature of the machine is too high.

As shown in Figure 5, it is a kind of conventional power conditioner, and its structure includes a base (60), establishes two opposite side plates (70) on the base (60), on the base (60) and A plurality of electrical components and a circuit board are arranged between two opposite side plates (70), and then with a loam cake (80), lock the loam cake (80) downwards with a plurality of screws (81) respectively, and put the loam cake (80) is screw-locked on the side plate (70), but, the shortcoming of above-mentioned conventional power conditioner in actual use is:

Insufficient safety, prone to electric shock hazard: because the upper cover (80) is at best only sealed on the two opposite side plates (70), at the front and rear upper positions of the power regulator, that is, the side plates (70) The front and rear positions between the side plate (70) and the upper cover (80) are respectively hollowed out. During use, it is very easy for people to mistakenly touch the internal parts of the power regulator through the front and rear positions between the side plate (70) and the upper cover (80). The electrical parts installed in the system lead to the risk of electric shock, and its safety is in danger, so it is necessary to improve it.

【Content of utility model】

The purpose of the utility model is to provide a protective cover for a power regulator, which can protect people from the danger of electric shock.

In order to achieve the above purpose, the utility model provides a protective cover for a power regulator, which is provided with a base on the power regulator, and a fan is arranged at one end of the base; two opposite side plates are arranged on the base , the outer side of the upper part of the side plate is respectively provided with a concave slide rail, and an upper cover is arranged on the side plate; it is characterized in that:

A plastic protective cover is respectively set at the front and rear positions above the power regulator. The protective cover is L-shaped. The protective cover includes a top and a longitudinal part. The protective cover is respectively covered on the front and rear of the power regulator. Position, on the opposite side inside the protective cover respectively protrudes a protruding strip inwardly, and each protruding strip is respectively positioned correspondingly to each slide rail embedded in the side plate.

The protective cover of the power regulator is characterized in that: a hole is respectively set on both sides of the longitudinal part of the protective cover.

The protective cover of the electric power regulator is characterized in that: a bump is respectively provided on the lower edge of the top of each protective cover, and through holes are respectively provided at the front and rear positions of the top of the upper cover, and the bumps are respectively snapped into the Positioning at the through hole.

The protective cover of the power regulator is characterized in that a removable sheet is provided at the lower part of the hole.

To sum up, the protective cover of the power regulator of the present invention can protect the upper, upper front and upper rear positions of the power regulator, and can prevent people from getting an electric shock. Each protective cover of the utility model forms a T-shaped hole on both sides of the longitudinal part respectively, and a removable sheet is arranged at the bottom of the hole.

【Detailed ways】

The utility model is a protective cover for a power regulator, please refer to Figs. 1, 2 and 3, and the power regulator is provided with:

A base (10) capable of dissipating heat is provided with a fan (11) having a cooling effect at one end of the base (10);

Two opposite side plates (20) are arranged on the base (10), and a concave slide rail (21) is formed on the upper outer side of each side plate (20), respectively, and two opposite side plates (20) are provided with A loam cake (30) that can be covered on the power regulator, forms a through hole (31) respectively at the front and rear positions of the top of the loam cake (30);

There is a protective cover (40) made of plastic, slightly L-shaped from the side view, which includes a top (401) and a longitudinal part (402), and the protective cover (40) can be used to cover the top of the power regulator At the front and rear positions, a protruding strip (41) is protruded inwardly on the opposite side of the protective cover (40), and each protruding strip (41) can be respectively provided for corresponding to each slide rail (21) and fitting positioning; A T-shaped hole (42) is respectively formed on both sides of the longitudinal part (402) of the protective cover (40), and a removable sheet (421) is arranged at the bottom of the hole (42). Each hole (42) The function is to be used for wiring and fixing of wires;

A protruding particle (43) (as shown in Figure 4) is formed at the lower edge of the top (401) of the protective cover (40) relative to the through hole (31), and each protruding particle (43) can be positioned on each relative through hole (31).
