Abstract
The utility model discloses a junction box, which is mainly composed of a junction box body and a wire pressing block. The utility model is characterized in that grooves with different width and depth are arranged on the junction box body and the wire pressing block in a same axial direction, leading-out cables pass through the grooves, and then the junction box can realize that the cables with different outer diameters can be fixed and sealed. The junction box has the advantages of reasonable structure, easy production and convenient use.
Description
Technical field
The utility model relates to a kind of terminal box, particularly relates in the solar module, is used for the terminal box of electrical cable wiring.
Background technology
The solar module terminal box is used to realize the generator unit of component internal and being electrically connected of external circuit, and realizes the sealing that assembly output connects, for mechanical fasteners and the sealing that realizes external cable.Prior art has adopted the means of bonding or welding at the cable inlet place, as among Fig. 1 cable being put into groove, utilize closely cooperating of 2 of terminal box body 1 and welding press strips, cover connector cover, realize mechanical connection and sealing by the strain of output cable 3.Because the size between each part of crimping cooperates requirement, limited the cross section and the model specification of cable, when needs adopt new cable model or conductor cross-section, the mould that must more renew.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of terminal box, and it can adapt to different size model cable, the mould that need not more renew.
For solving the problems of the technologies described above, terminal box of the present utility model, mainly form by box body, lid, line ball piece and cable, comprise binding post and circuit in the box body, on box body and line ball piece or be provided with the different in width of two or more same axial distribution and the groove of the degree of depth on one of them, outgoing cable is by passing in the groove.
The utility model has been realized the tight crimping of cable of various outer diameter owing to taked above technical measures, and rational in infrastructure, is easy to make, and is easy to use.

Fig. 2 is the utility model terminal box schematic diagram
Fig. 2-the 2nd, the utility model terminal box line ball piece schematic diagram
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 2, terminal box body 1 is provided with major diameter pressuring line groove 2 and minor diameter pressuring line groove 3, is provided with similar groove with major diameter pressuring line groove 2, minor diameter pressuring line groove 3 corresponding sections on the line ball piece 4.Micro-structural on the groove is used for fixing cable 5,6.Major diameter pressuring line groove 2 and minor diameter pressuring line groove 3 directly match with the line of two kinds of insulated conductors that may use respectively.Line ball piece 4 and terminal box body 1 mutually after the welding, can be realized the installation of two kinds of not collinear footpath cables.
The utility model has adopted coaxial distribution at the line ball place, has had several sections grooves of different curvature radius, to adapt to the tight crimping of cable with various outer diameter.
