Detailed Description

The embodiments of the utility model will be further described with reference to the accompanying drawings in which:

as shown in fig. 1-2, a junction box comprises a box body 3 and nut assemblies 4, wherein mounting grooves 31 are correspondingly formed on the side walls of the left side and the right side of the box body 3, and two sets of nut assemblies 4 are arranged and are respectively inserted into the two mounting grooves 31.

Nut component 4 includes connecting block 1, nut 2, the lateral wall of connecting block 1 is provided with spacing ka tai 14, inserts the mounting groove 31 back when nut component 4, connecting block 1's spacing ka tai 14 forms spacing cooperation with box body 3, avoids connecting block 1 to deviate from mounting groove 31. Wherein, spacing ka tai 14 can be microscler arc boss, forms the cambered surface direction, and the operation of easy to assemble.

Of course, the position that also can correspond the mounting groove both sides at the lateral wall of box body corresponds sets up the elasticity buckle, and it is spacing to form the connecting block through the elasticity buckle, avoids the connecting block to deviate from the mounting groove.

As shown in fig. 3 to 5, the nut assembly 4 includes a connecting block 1 and a nut 2, a nut groove 11 having an open front end is integrally formed on the connecting block 1, and an elongated connecting hole 12 which is arranged in a front-rear direction and vertically penetrates the nut groove 11 is further formed on the connecting block 1.

The nut 2 is slidably arranged in the nut groove 11 in a front-back direction, and the threaded hole of the nut 2 corresponds to the elongated connecting hole 12.

By adopting the scheme, the nut 2 can be directly installed into the nut groove 11 through the front end opening of the nut groove 11, the nut 2 can slide back and forth along the nut groove 11 to realize position adjustment, the left and right directions of the nut 2 are reliably limited, the alignment of the threaded hole of the nut 2 and the long connecting hole 12 is ensured, meanwhile, when the screw is screwed in, the nut cannot deviate, and the operation is more convenient.

Compared with the prior art, need not additionally to set up limit stop's structure, not only reduced the part, optimized the structure, reduced the cost moreover.

Furthermore, the nut groove 11 is opened at the front and rear ends, that is, the front and rear ends of the nut groove 11 are opened, so that the adjustment of the front and rear positions of the nut 2 in the nut groove 11 and the dismounting operation of the nut 2 are more convenient.
