Description

Technical Field

[0001] The present invention relates to the technical field of BIPV component cables and metal roof panel edge locking joints, and more specifically to a bridging fixture used for photovoltaic component cables to cross the edge locking. Background Art

[0002] After the B IPV photovoltaic modules are installed on the metal roof panels, the module cables often go over the metal roof panels during the series connection process. Since the lock edge is higher than the module plane, the cables at the lock edge extend beyond the module plane to form an obstruction, resulting in hot spots on the photovoltaic modules and inability to fix them firmly. In addition, the cleaning robot is prone to dragging the module cables when cleaning the dust on the modules, which poses the risk of cable breaking and MC4 connector disengagement, causing leakage, power outages, etc., which may lead to safety accidents.

[0003] Therefore, providing a bridging fixture for photovoltaic module cables to cross the locking edge is an issue that needs to be urgently solved by those skilled in the art.

[0004] invention

[0005] In view of this, the present invention provides a jumper fixture for photovoltaic module cables to cross the locking edge, so as to firmly fix the cables of the locking edge components across the metal roof panel, solve the risks of hot spots caused by cable shielding components, solve the risks of cable breaking and MC4 connector disengagement caused by robot cleaning, and avoid the occurrence of safety accidents.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A bridging fixture for photovoltaic module cables to cross the locking edge, comprising two interlocking mounting seats to form a front-to-back through-going cavity for the locking edge to pass through; each of the mounting seats has a cavity for the cable to be embedded inside, and the two cavities are connected; each of the cavities has outlet holes on both sides for the cable to pass through.

[0008] By adopting the above technical solution, the beneficial effects of the present invention are:

[0009] The module cables crossing the locking edge of the roof panel can be firmly fixed to avoid the module cables being dragged and broken and blocking the modules to cause module hot spots. At the same time, the structure is simple and can greatly save installation costs.

[0010] Furthermore, each of the mounting seats includes an outer positive buckle section, an outer negative buckle section, an inner negative buckle section and an inner positive buckle section which are connected as one body to form the cavity, wherein the outer positive buckle section and the outer negative buckle section are symmetrically distributed on the left and right, the inner negative buckle section and the inner positive buckle section are symmetrically distributed on the left and right, the outer positive buckle section is located directly above the inner positive buckle section, and the outer negative buckle section is located directly above the inner negative buckle section; the outer positive buckle section includes a first buckle section which is recessed into the outer surface of the outer positive buckle section body. A circular arc-shaped buckling edge, wherein the first circular arc-shaped buckling edge is provided with a first buckle protrusion; the inner positive buckling section includes a second circular arc-shaped buckling edge recessed into the outer surface of the inner positive buckling section body, and the second circular arc-shaped buckling edge is provided with a second buckle protrusion; the outer negative buckling section includes a third circular arc-shaped buckling edge flush with the outer surface of the outer negative buckling section body, and the third circular arc-shaped buckling edge has a first buckle groove; the inner negative buckling section includes a fourth circular arc-shaped buckling edge flush with the outer surface of the inner negative buckling section body, and the fourth circular arc-shaped buckling edge has a second buckle groove.

[0011] Furthermore, the number of the first snap-fit ​​protrusion, the second snap-fit ​​protrusion, the first snap-fit ​​slot and the second snap-fit ​​slot are all two.

[0012] It can be seen that the present invention provides a jumper fixing for photovoltaic module cables to cross the locking edge. Compared with the prior art, the present invention can directly wrap and fix the module cables that cross the locking edge of the roof panel, preventing the cables from being damaged by external forces and increasing the risk of safety accidents. At the same time, it has a simple structure and is easy to install without causing damage to the original module equipment. BRIEF DESCRIPTION OF THE DRAWINGS
