fig. 2 is a schematic view of the main housing structure of the present invention.

Detailed Description

As shown in fig. 1-2, a special protection device for a low-voltage surge protector comprises a main housing 1, wherein a left connector 2 and a right connector 3 are respectively arranged on the left side and the right side of the main housing 1, and the special protection device further comprises a shunt housing 4, wherein a handle 5, a tripping mechanism, an electrode plate 6, a coil assembly and an arc extinguishing assembly corresponding to the structure and the position of the main housing 1 are arranged on the shunt housing 4, and a mounting groove 7 for mounting each element is arranged on the shunt housing 4. In terms of layout, the internal structure of the shunt casing 4 contains necessary components, such as mechanical linkage structure, and the wire connecting part 12 can be directly connected with the main casing 1. The shunt casing 4 is fixed with the lock joint between the main casing body 1, handle 5 and tripping device construct the linkage assembly with the main casing body 1 corresponding structure respectively, the outer fringe department of shunt casing 4 is equipped with the arc grooving 8 that supplies the wire to pass, be equipped with the lead wire extension board 9 that passes arc grooving 8 on the main casing body 1, lead wire extension board 9 tip is equipped with and supplies the wire to pass the fluting 10 of being connected with right side joint 3. In the opposite plane of mounting, the peripheral profile of the shunt housing 4 is missing parts compared to the main housing 1. Meanwhile, the arc-shaped cutting groove 8 enables the lead in the main shell 1 to extend out, and the lead is relatively limited through the lead support plate 9, so that the circuit and the structure are stable.

The electrode plate 6 comprises a contact part 11 and a connecting part 12 which are connected, and the contact part 11 is of a disc-shaped structure. The contact surface or the area of the opposite surface is increased, so that the circuit path is effectively stabilized, and the reaction efficiency can be improved.

The electrode plate 6 is covered by a plastic part 13, and the plastic part 13 is provided with a plurality of uniformly arranged open holes 14. The insulating coating can prevent rust and damage and prolong the service life of the electrode plate 6.

Arc extinguishing assembly includes arc-extinguishing chamber and arc striking piece 15, the electric connection between 15 one end of arc striking piece and the arc-extinguishing chamber, and the arc striking piece 15 other end and the 3 electric connections of right side joint. The connection mode is the same as that of a common product, but the difference is that the main shell 1 and the arc extinguishing component are connected with the right connector 3 in common.

The shunt shell 4 and the main shell 1 are in guide butt joint through a socket structure. Avoid using the buckle structure for a long time and appear the deviation, guide through the socket joint structure. The socket structure, i.e., the pipe bore, is not illustrated or limited herein.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
