Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is referred to, in the embodiment of the present invention, a kind of photovoltaic component terminal box, including mounting seat 1, mounting seat 1 sets
Put in terminal block housings 2, the side of mounting seat 1 is provided with connection jaws 3, the middle part of mounting seat 1 is provided with conducting block 6, and conducting block 6 sets
There are four and be uniformly distributed, the front end of conducting block 6 is provided with card interface 4, card interface 4 abuts against the side of connection jaws 3, set on conducting block 6
