Abstract
The invention discloses a solar photovoltaic connecting box, and belongs to the field of solar photovoltaic power generation devices. In order to effectively reduce the line loss of a solar power generation system and improve the transfer efficiency of a solar cell, the solar photovoltaic connecting box changes the position of a cable outlet hole of the solar photovoltaic connecting box, reduces the length of connecting cables between solar photovoltaic connecting boxes, and achieves the purpose of reducing the internal resistance of the solar photovoltaic connecting box, and meanwhile protruding ribs are added on the inner wall of the cable outlet hole, the cables are enabled not to rotate or move, and the performance of the solar photovoltaic connecting box is more stable.
Description
Technical field
The present invention relates to a kind of photovoltaic terminal box, belong to the solar energy power generating apparatus field.
Background technology
At present the operation principle of general solar energy equipment is that solar panel by solar units carries out opto-electronic conversion with the sunlight that receives, then by controller for solar with electrical power storage in storage battery, each solar units assembly is in a terminal box, existing photovoltaic terminal box adopts outlet in the same way, when being connected between terminal box, cable needs transition arc, increased cable length, the line loss of solar power system increases, and affects the conversion efficiency of solar cell.
Summary of the invention
For the defective that the above-mentioned background technology exists, the technical problem to be solved in the present invention is to provide a kind of photovoltaic terminal box that reduces line loss.
For solving the problems of the technologies described above, the present invention is achieved by the following technical programs:
A kind of photovoltaic terminal box comprises box body and two wire holes that are positioned on described box side wall, and described wire hole lays respectively on the relative sidewall of described box body.
Compared with prior art, because the wire hole of terminal box lays respectively on the relative sidewall of box body, between terminal box when connecting, save the transition arc part of stube cable, reduced cable length, saved material cost, reduce the line loss of system, improved the conversion efficiency of solar cell.
As improvement of the present invention, be provided with the convex tendon of interruption at described box body through-hole wall circumferencial direction, stube cable is compressed in this wire hole, and neither can rotate can not axial endplay, makes photovoltaic terminal box service behaviour more stable.
Description of drawings
Fig. 1 is the front schematic view of photovoltaic terminal box of the present invention;
Fig. 2 is the cutaway view along E-E line in Fig. 1;
Fig. 3 is the enlarged drawing of I part in Fig. 2;
Fig. 4 is the cutaway view along F-F line in Fig. 2.
Embodiment
In order to make technical scheme of the present invention more aobvious and understandable, the present invention is further illustrated below in conjunction with the drawings and specific embodiments.
The stube cable 2 of photovoltaic terminal box one end of the present invention shown in Figure 1 is not shown.
With photovoltaic terminal box series connection of the present invention shown in Figure 1 the time, terminal box wire hole 3 perforate directions are consistent with the closure of stube cable 2, therefore stube cable 2 connects for straight line, the terminal box of prior art same side output terminal is when being connected in series, because of terminal box wire hole perforate direction and cable closure inconsistent, therefore certainly will there be the transition arc part in stube cable.
For the electrical property that makes photovoltaic terminal box of the present invention more stable, as shown in Figure 2 and Figure 3, be provided with the convex tendon 4 of interruption on terminal box wire hole 3 inwalls, after stube cable 2 access photovoltaic terminal box bodies 1, convex tendon 4 is pushed down stube cable 2, and stube cable 2 neither can be rotated can not axial endplay; As shown in Figure 4, described convex tendon 4 is 4 sections on box body wire hole 3 inwall circumferencial directions and does symmetrical uniformly, and it is better to stube cable 2 fixed effects.
In addition to the implementation, the present invention can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
Claims (3)
