Abstract:
A frame is provided for highly-concentrated photovoltaic cells. The frame uses vertical and horizontal rods. Connectors are fixed at where the vertical and horizontal rods connect. The frame is constructed with the rods and connectors coordinated with fixing components. Thus, solar cell receivers can be directly set at any place on the frame; and the frame can be easily constructed and safely moved. Furthermore, location space is effectively used and weather resistance is achieved.

Description:
TECHNICAL FIELD OF THE INVENTION 
       [0001]    The present invention relates to a frame for solar cells; more particularly, relates to using horizontal rods and vertical rods to form a frame coordinated with connectors having fixing components prevented from being exposed, where solar cell receivers can be directly set at anywhere of the frame and the present invention can be assembled rapidly and moved easily and effectively use location space while is weather-resisting. 
       DESCRIPTION OF THE RELATED ARTS 
       [0002]    For assembling a solar cell module, a frame  3  uses prisms  31  coordinated with screws  32 . Yet, the assembling procedure is complex and the screws  32  get rust easily owing to their exposure. Besides, the exposed head part of the screw  32  may hurt human finger owing to its sharp edge. The rusted screws  32  may even make maintenance or de-assembly of the frame difficult. 
         [0003]    In the other hand, an ‘L’-shape connector is usually used for connecting rods of the frame on assembling the frame. However, the ‘L’-shape connector is directly fixed on the rod and makes use of location shape not effective enough for holding solar cells. Hence, the prior arts do not fulfill all users&#39; requests on actual use. 
       SUMMARY OF THE INVENTION 
       [0004]    The main purpose of the present invention is to use horizontal rods and vertical rods to form a frame coordinated with connectors having fixing components prevented from being exposed, where solar cell receivers can be directly set at anywhere of the frame and the present invention can be assembled rapidly and moved easily and effectively use location space while is weather-resisting. 
         [0005]    To achieve the above purpose, the present invention is a frame using interior connectors for holding highly-concentrated solar cells, comprising a frame body and a plurality of connectors, where the frame body comprises a plurality of horizontal rods and a plurality of vertical rods; the vertical rods are perpendicular to the horizontal rods; each horizontal rod has two vertical rods separately at two ends of the horizontal rod; each horizontal rod has a first flute on an inner surface of the horizontal rod; each vertical rod has a second flute on an inner surface of the vertical rod; each first flute is adhered to two second flutes; and each connector is fixed in a first flute and a neighboring second flute. Accordingly, a novel frame using interior connectors for holding highly-concentrated solar cells is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0011]    The following description of the preferred embodiment is provided to understand the features and the structures of the present invention. 
         [0012]    Please refer to  FIG. 1  to  FIG. 3 , which are an explosive view and a perspective view showing a preferred embodiment according to the present invention and a view showing area a of  FIG. 2 . As shown in the figures, the present invention is a frame using interior connectors for holding highly-concentrated solar cells, comprising a frame body  1  and a plurality of connectors  2 . 
         [0013]    The frame body  1  comprises a plurality of horizontal rods  11  and a plurality of vertical rods  12 . Every horizontal rod  11  has two vertical rods  12  separately set at two ends of the horizontal rod  11 . The horizontal rod  11  and the vertical rod  12  have a first flute  111  and a second flute  121  on inner surfaces of the horizontal rod  11  and the vertical rod  12 , respectively. Every first flute  111  is adhered to two second flute  121 . The horizontal rods  11  and the vertical rods  12  are made of metal materials or non-metal materials. The horizontal rod  11  and the vertical rod  12  have limit slots  112 , 122  on the first flute  111  and the second flute  121 , separately. Each limit slot  112 , 122  on the first flute  111  and the second flute  121  has a width wider than the first flute  111  and the second flute  121 , respectively. 
         [0014]    Every connector  2  is fixed in the first flute  111  of the horizontal rod  11  and the adhering second flute  121  of the vertical rod  12 . Every connector  2  is made of a metal material or a non-metal material. Every connector  2  comprises a first scarfing part  21 , a second scarfing part  22  and two fixing parts  211 , 221 , where the first scarfing part  21  is set in the first flute  111  of the horizontal rod  11 ; the second scarfing part  22  is connected with the first scarfing part  21  and is set in the second flute  121  of the vertical rod  12 ; and the fixing parts  211 , 221  are set at an end of the first scarfing part  21  and an end of the second scarfing part  22 , separately, and are contained in the limit slots  112 , 122 . Each fixing part  211 , 221  is wider than the first or the second scarfing part  21 , 22  where the fixing part  211 , 221  is located in. Each fixing part  211 , 221  is corresponding to a limit slot  112 , 122  and has a circular shape or a polygonal shape. The first scarfing part  21  and the second scarfing part  22  of the connector are perpendicular to each other to form an ‘L’-shape of the connector  2 . Every fixing part  211 , 221  has a screw hole  212 , 222  for being fixed to the limit slot  112 , 122  of the first or the second flute  111 , 121  with coordination of a fixing component  23 , where the fixing component  23  is a bolt or a fixing screw. When the fixing component  23  is a bolt, no tool is needed for assembling the present invention. Thus, a novel frame using interior connectors for holding highly-concentrated solar cells is obtained. 
         [0015]    On assembling the present invention, two ends of every neighboring horizontal rod  11  and vertical rod  12  are connected with each other to form the frame body  1  with the horizontal rods  11  and the vertical rods  12 . The first flute  111  and the second flute  121  of the horizontal rod  11  and the vertical rod  12  are adhered and perpendicular to each other, respectively. The first scarfing part  21  and the second scarfing part  22  of the connector  2  are respectively embedded in the neighboring first flute  111  and second flute  121  of the horizontal rod  11  and the vertical rod  12 . The fixing parts  211 , 221  at an end of the first scarfing part and an end of the second scarfing part  22  are contained in the limit slots  112 , 122 , separately. At last, through the screw holes  212 , 222  of the fixing parts  211 , 221 , the fixing components  23  are used to fix and combine the horizontal rods  11  and the vertical rods  12  to form a frame rapidly. The horizontal rods  11  and the vertical rods  12  use the first flute  111  and the second flute  121  coordinated with the connectors  2  to form the frame body  1  while the fixing components  23  is prevented from being exposed. Thus, solar cell receivers can be directly set at anywhere of the frame; human fingers would not be cut by the out-exposing fixing components  23 ; and the fixing components  23  will not easily get rust. Hence, the present invention can be moved easily and effectively use location space while is weather-resisting. 
         [0016]    To sum up, the present invention is a frame using interior connectors for holding highly-concentrated solar cells, where horizontal rods and vertical rods are used to form a frame coordinated with connectors while fixing components is prevented from being exposed; solar cell receivers can be directly set at anywhere of the frame; and the present invention can be assembled rapidly and moved easily and effectively use location space while is weather-resisting.
