Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment, referring to Fig. 1～shown in Figure 6:

As shown in Figure 1 and Figure 2, this terminal box includes lid 1 and box body 2, has card base 11 on the lid 1, and box body 2 has draw-in groove 21 at the outer circumferential side of corresponding card base 11, and card base 11 and draw-in groove 21 match and can realize being fastened and connected of lid 1 and box body 2.Also be connected with the joint 22 of the lead of can pegging graft on the box body 2 fore sidewalls, the bottom surface of box body 2 has four and these box body 2 integrated, mutual junction blocks 23 side by side, be equipped with supporting base 3 in each junction block 23, be parallel with bypass diode 4 between the adjacent supporting base 3.Said structure is a prior art, in existing terminal box application is arranged all, does not elaborate at this.

Inventive point of the present utility model is the supporting base structure is improved, and the connected mode of bypass diode has been made adjustment.
