Problems solved by technology
[0002] Some of the existing terminal junction boxes have no shielding structure, which cannot play the role of electromagnetic shielding, and are easy to interfere with other electronic components inside and outside the box
Some terminal junction boxes are non-assembled, the structure is relatively complex, the process requirements are high, and the cost is also high
Some terminal junction boxes use non-metal shells, the structural strength, stability, and reliability of the product are not very high, and the flame retardancy is not very good.

Embodiment Construction
[0040] The present invention will be further explained below in conjunction with the drawings: Examples: figure 1 , figure 2 , A metal junction box with electromagnetic shielding function, divided into two types, positive and negative, positive and negative signs are set on the cover, the internal structure is the same, only the positive and negative signs 101 and 102 of the upper cover are different. The specific structure is as Figure 1 to Figure 19 , A metal junction box with electromagnetic shielding function, including a base 80, a cover 70, and a cable locking device, wherein:
[0041] The base 80 includes a metal lower shell 1, an insulating lower shell 2, a metal terminal 4 and a nut 5. The metal terminal 4 with the nut 5 assembled is assembled in the insulating lower shell 2, and the insulating lower shell 2 is connected to the metal lower shell by a buckle 21 1 is connected and fixed, the metal terminal 4 extends through the insulating lower shell 2 to the outside of ...

The invention discloses a split metal junction box with an electromagnetic shielding function. The split metal junction box at least comprises a base and a cover board, wherein a cable locking deviceis arranged on the side surface of the base; and a cable passes through the cable locking device and is connected with a metal terminal in the base through the cable locking device. A lower metal shell, an upper metal shell and the cable locking device can be provided with seal rings to achieve a waterproof function; and after a product is assembled, the lower metal shell, the upper metal shell, the cable locking device and a shielding layer of the cable can be conducted in an omnibearing manner to form a fully enclosed structure, thereby achieving a good electromagnetic shielding function. Byadopting the scheme of a lining insulator of a split metal housing and the metal terminal, assembly is simple and the process difficulty and cost are reduced.
Description
Technical field [0001] The invention discloses a split metal junction box with electromagnetic shielding function, which belongs to the technical field of connector equipment and is mainly used for the connection and conduction of a new energy electric vehicle battery box body and a cable. Background technique [0002] Some of the existing terminal junction boxes do not have a shielding structure, which cannot play an electromagnetic shielding effect, and easily interferes with other electronic components inside and outside the box. Part of the terminal junction box is non-assembled, the structure is more complicated, the process requirements are higher, and the cost is higher. Some terminal junction boxes use non-metallic shells, and the structural strength, stability, and reliability of the product are not very high, and the flame retardancy is not very good. Summary of the invention [0003] In view of the shortcomings of the prior art, the present invention provides a split m...
