Abstract

The utility model discloses a terminal protection cover, which comprises a baffle plate and plug posts for inserting into the concave holes of the mounting screws of the terminals, and the plug posts are respectively arranged in pairs on the same side of the baffle plate. side. The terminal protective cover of the utility model can be conveniently installed on the terminal block, and the live exposed part of the terminal block is sealed and isolated, which effectively prevents the personal electric shock accident of the staff and the tripping of the equipment power supply due to negligence; On the other hand, since the exposed metal part of the terminal block is sealed and isolated, the impact of long-term metal oxidation on the conductivity of the terminal block is effectively reduced, and the safety and stability of the power supply of the equipment are improved.

Description

Terminal protection cover

technical field

The utility model relates to a terminal protective cover.

Background technique

At present, the terminal block has been widely used for the connection of AC cables, as shown in Figure 1, due to design reasons, the screws in the concave holes 31 and 32 for installing screws of the terminal block and the groove 4 between the two rows of concave holes The central connecting piece part is all metal material and is exposed outside. In daily work, if the staff is negligent, they may accidentally touch the live exposed part of the terminal block and cause an electric shock, resulting in personal injury and equipment power tripping, which will affect personal safety and equipment operation. On the other hand, long-term exposure of the above-mentioned metal parts will affect the conductivity of the terminal block due to oxidation, and will also affect the safety of the power supply of the equipment.

Utility model content

In view of the above-mentioned defects in the prior art, the problem to be solved by the present invention is to provide a terminal protection device for preventing electric shock and oxidation.

In order to solve the above problems, the utility model provides a terminal protective cover, which includes a baffle plate and inserting posts for inserting into the concave holes of the mounting screws of the terminals, and the inserting posts are respectively arranged in pairs on the on the same side as the baffle described above.

Preferably, the insertion post is cylindrical.

Preferably, the baffle and the plugging posts are made of insulating materials.

Preferably, multiple pairs of the insertion posts are provided on the baffle.

The terminal protection cover of the utility model has the beneficial effects of the following aspects:

The terminal protective cover of the utility model can be conveniently installed on the terminal block, and the live exposed part of the terminal block is sealed and isolated, which effectively prevents the personal electric shock accident of the staff and the tripping of the equipment power supply due to negligence; On the other hand, since the exposed metal part of the terminal block is sealed and isolated, the impact of long-term metal oxidation on the conductivity of the terminal block is effectively reduced, and the safety and stability of the power supply of the equipment are improved.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.

As shown in Figure 1 and Figure 2, the terminal protective cover of the present invention specifically includes the baffle plate 1 and the insertion posts 21 and 22 in the concave holes 31 and 32 for inserting the mounting screws of the terminals, the insertion posts 21 and 22 22 are respectively arranged in pairs on the same side of the baffle plate 1 . Wherein the shape and size of the plug posts 21 and 22 match the shape and size of the screw holes 31 and 32 of the corresponding terminals, and the distance between the paired two plug posts 21 and 22 is the same as that of the corresponding two terminals. The distance between the recessed holes 31 and 32 where the screws are installed matches.

As shown in FIG. 2 , in a preferred embodiment of the present invention, the insertion posts 21 and 22 are cylindrical. The shape of the insertion post is not limited thereto, and it can be in various prism shapes, as long as it matches the shape and size of the concave hole and can protect the terminal block.

In addition, in the accompanying drawing 2, only a pair of plug posts 21 and 22 are provided on the baffle plate 1, but the terminal protection cover of the present utility model is not limited thereto, and multiple pairs of plug posts meeting the requirements can be provided on the baffle plate 1 at the same time. post to provide protection for multiple terminals at the same time.

In order to make the terminal protection cover of the utility model play a better role, the baffle plate and the plug-in post can be made of insulating materials, such as insulating resin, insulating rubber, wood, etc.

When the terminal protective cover of the utility model is in use, the staff wears insulating gloves, and directly inserts the two plug posts 21 and 22 of the terminal protective cover into the screw concave holes 31 and 32 of the terminal row respectively. The size of the part matches the size of the terminal. The baffle plate 1 of the terminal protective cover will completely close the two screw holes 31 and 32 of the terminal block and the intermediate metal connecting piece, and play the role of insulation isolation protection and reduction of the live part of the terminal block. The metal part of the small terminal row is affected by the decline in electrical conductivity caused by long-term oxidation. The terminal protective cover of the utility model has a simple structure and is easy to use, and can be widely used in the protection of the terminal row in various occasions.

Certainly, what is described above is the preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can be made without departing from the principle of the present utility model. And retouching are also regarded as the scope of protection of the present utility model.
