Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0019] like figure 1 As shown, the junction box of the present invention includes a box body 1 and a box cover 2 . The box body 1 includes a front wall 11 , a rear wall 12 opposite to the front wall 11 , and a left side wall 13 and a right side wall 14 connecting the front wall 11 and the rear wall 12 . The four walls are surrounded by an accommodating cavity 15, and a plurality of terminals 3 arranged side by side are arranged in the accommodating cavity 15, and diodes 4 are arranged between adjacent terminals 3, and each diode 4 is provided with two pins, one of which is It is connected to one terminal 3, and th...

Abstract

The invention provides a junction box which comprises a box body and a box cover. The box body comprises a front wall, a rear wall opposite to the front wall, a left side wall and a right side wall, the left side wall and the right side wall are used for connecting the front wall and the rear wall, an accommodating cavity is defined by the four walls, a plurality of terminals arranged in parallel are arranged in the accommodating cavity, a diode is connected between adjacent terminals, and wire outlet holes are arranged on the front wall, the left side wall and the right side wall. The junction box can achieve 180-degree wiring, can also achieve 90-degree wiring, and prevents a cable from being cracked because of overbending.

Description

technical field [0001] The invention relates to a junction box, in particular to a photovoltaic junction box. Background technique [0002] In existing photovoltaic products, junction boxes are used more and more, and have become an important component for electrically connecting different components. The junction box needs to be electrically connected to external cables, and in some usage environments, the location of the cables and the location of the outlet holes on the junction box are not ideal. For example: the outlet hole is arranged on the side wall of the junction box, and the cable is at a position close to the front wall. In this case, the cable can only be connected to the outlet hole on the side wall after being bent. After a period of use, the part with a large bend on the cable is prone to cracking due to excessive tension. [0003] Therefore, it is necessary to provide a new junction box to overcome the above problems. Contents of the invention [0004] ...
