Problems solved by technology

[0002] At present, the mica sheet framework sold in the market, the fuse and the fuse are directly welded together, and then wound on the framework, the requirements for welding workers are relatively high, and the welding of the fuse and the fuse is relatively difficult. The workmanship is poor, and it is easy to cause damage to the fuse. If the welding quality is not good, the connection is not firm, and abnormal fusing is prone to occur.

Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

[0033] see figure 1 , figure 2 and image 3 , The best embodiment of the present invention, a mica sheet skeleton, including a skeleton body 1, a connector 2 and two contact plates 3. The axial cross-section of the skeleton body 1 is in the shape of a cross, and the skeleton body 1 is formed by connecting four mica sheets 11, and the left and right ends of each mica sheet 11 are respectively provided with tentacles engaging holes 12, and each mica sheet 11 is provided with Fuse card slot 13 and fuse card slot 14. The two contact plates 3 are arranged on the two axial ends of the skeleton body 1 in one-to-one correspondence, and the connecting piece 2 is arranged between two adjacent mica sheets 11 of the skeleton body 1 .

Abstract

The invention discloses a mica sheet skeleton. The mica sheet skeleton comprises a skeleton body, a connecting piece and two contact plates; the axial section of the skeleton body is crossed; the skeleton body is formed by connecting four mica sheets; contact clamping holes are formed in the left and right ends of each mica sheet; each mica sheet is provided with a fuse piece clamping groove and a fuse wire clamping groove; the two contact plates are correspondingly arranged at two axial ends of the skeleton body one to one; the connecting piece is arranged between two adjacent mica sheets of the skeleton body; each contact plate comprises a circular plate, a trapezoidal plate and three contacts; and a crossed hole is formed in the middle part of each circular plate. The mica sheet skeleton is simple in structure and low in cost; and fuse wires and fuse pieces are connected through the connecting piece, so that the connecting quality is reliable, and the abnormal melting phenomenon is prevented.

Description

technical field [0001] The invention relates to a mica sheet skeleton. Background technique [0002] At present, the mica sheet framework sold in the market, the fuse and the fuse are directly welded together, and then wound on the framework, the requirements for welding workers are relatively high, and the welding of the fuse and the fuse is relatively difficult. The workmanship is poor, and it is easy to cause damage to the fuse. If the welding quality is not good, the connection is not firm, and abnormal fusing is prone to occur. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a mica sheet skeleton with simple structure and low cost. The fuse and the fuse are connected through connecting parts, the connection quality is reliable, and abnormal fusing phenomenon is avoided. [0004] The technical solution to achieve the above object is: a mica sheet skeleton, including a skeleton body, a conn...
