Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of prior U.S.
provisional application 61/383,812, which is entitled "CONNECTION
OR JUNCTION BOX" and filed on Sep. 17, 2010. The entire disclosures
of the above-captioned application are incorporated herein by
reference.
FIELD OF THE INVENTION
[0002] The present invention relates to a junction box, and more
particularly to a junction box for solar module and a conductor
strip connection device thereof.
BACKGROUND OF THE INVENTION
[0003] There are several advantages of photovoltaic solar power
that make it one of the most promising renewable energy sources in
the world. The photovoltaic solar power is free, needs no fuel and
produces no waste or pollution, and the solar power generator
requires little maintenance and no supervision and has a life of
20-30 years with low running costs. Solar power generators are
simply distributed to homes, schools, or businesses, where their
assemblies require no extra development or land area and their
functions are safe and quiet. Remote areas can easily produce their
own supply of electricity by constructing as small or as large of a
system as needed.
[0004] Generally, the solar or photovoltaic module for generating
electric energy from sunlight comprises a plurality of solar or
photovoltaic cells. The solar cells in a solar module are usually
connected to each other by thin conductor strips (i.e. conductor
ribbons). These thin conductor strips are routed out of the solar
module on the side facing away from the sun. The thin conductor
strips are mostly made of copper foils and protruded from the rear
side of the solar module (i.e. solar panel). These flexible and
thin conductor strips are very sensitive and difficult to contact.
Therefore, one or more junction boxes are employed for the solar
module and thin conductor strips are manually contacted with
electrical terminal receptacles of the junction box. In addition,
the junction box is an integral part of a solar or photovoltaic
system and it provides electrical connections between the solar
cells of the individual solar module (i.e. solar panel) and between
the solar modules and other components of the system (i.e. DC/AC
inverter). Generally, the junction box is disposed on a rear
surface of the solar panel and has electrical connection mechanism
in the interior for contacting the thin conductor strips of the
solar modules and conducting the electrical current generated by
the solar modules to the outside. Without a junction box, the solar
modules could not work properly.
[0005] Generally, plural solar modules are operated in series
connection, wherein a so called bypass diode is anti-parallel
connected to each solar module. The bypass diode is disposed inside
the junction box and fastened and connected to the electrical
connection mechanism of the junction box. In a case of a solar
module is shaded or does not produce electricity because of defect,
this solar module would lower the power of the solar modules in
series connection or even suffers damage without bypass diode. This
is because that if a solar cell within a solar cell group of the
solar module is partially shaded, this shaded solar cell acts as a
blocking diode or resistor within the circuit of the solar cell
group, which may result in a damage of the shaded solar cell and
result in the entire solar cell group of the solar module no longer
being able to supply electric energy. The above-mentioned
situations can be avoided by using the bypass diode of the junction
box, because the current flows through the diode and is sustained.
In other words, the bypass diodes are electrically connected in an
anti-parallel manner with respect to the solar cell groups and have
the effect that the current flow through the solar module is led
past solar cell groups that only supply low power, i.e. the
terminals of this solar cell group of a solar module are
short-circuited by the bypass diode and the corresponding cell
group is bypassed thereby. Thus, such a solar cell group does no
longer contribute to the overall performance of the solar module,
but the overall current flow through the solar panel is
substantially unobstructed and a damage of individual solar cell is
avoided.
[0006] It is obviously that due to the mechanical conditions
particularly the form of the thin conductor strips and the bypass
diodes, a number of difficulties occur when constructing the
junction box. In addition, due to the manual connecting, the
assembly and installation of the thin conductor strips and the
bypass diodes with the electrical connection mechanism inside the
junction box is cost and laborious. Up to now, the conventional
junction box is complex in construction and installing the junction
box is laborious. In addition, the conventional junction box
doesn't provide reliable electrical connections and the durability
of the junction box is low. It is therefore desirable to provide a
junction box that is simple in structure, cost-effective, durable
enough to withstand a wide range of environment conditions and
easily be installed and maintained, while maintaining a
high-quality, reliable electrical connections between the
components of a solar or photovoltaic system.
SUMMARY OF THE INVENTION

solar module to the junction box easily.

deformation of the contact member 121.
[0030] FIGS. 4A and 4B are schematic views showing the operation of
the conductor strip connection device of FIGS. 3A and 3B. As shown
in FIGS. 3A, 3B, 3C, 4A and 4B, when the user wants to assemble and
connect the conductor strips 2 with the junction box 1, the user
can push the handle 1222 of the lever 122 for allowing the lever
122 to be rotated and switched toward the first position (as shown
in FIG. 4A). When the lever 122 is rotated and switched toward the
first position, the suppressing portion 1221 of the lever 122 is
apart from the contact segment 1211 of the contact member 121 and
the resilient member 124 contacts the bottom plate 1233 of the
carrying member 123 so that a gap g is formed between the
suppressing portion 1221 of the lever 122 and the contact segment
1211 of the contact member 121. Therefore, one conductor strip 2
can be inserted into the gap g between the suppressing portion 1221
of the lever 122 and the contact segment 1211 of the contact member
121 easily.
[0031] When one conductor strip 2 has been inserted into the gap g
between the suppressing portion 1221 of the lever 122 and the
contact segment 1211 of the contact member 121, the user can push
the handle 1222 of the lever 122 for allowing the lever 122 to be
rotated and switched toward second position (as shown in FIG. 4B).
During the process of switching the level 122 toward the second
position, due to the conductor strip 2 has been inserted into the
gap g, the suppressing portion 1221 continuously suppresses the
conductor strip 2 and the carrying member 123 is slightly moved
upwardly with respect to the contact member 121 or deformed when
the suppressing portion 1221 is moved and disposed into the gap g.
At this moment, the resilient member 124 is deformed and urges
against the bottom plate 1233 of the carrying member 123 so as to
limit the movement or deformation of the carrying member 123 and
provide a suppressing force to assist the suppressing portion 1221
of the level 122 to clamp or secure the conductor strip 2.
Therefore, the conductor strip 2 can be connected and secured with
the conductor strip connection device 12 by the clamping method
without using any auxiliary tool or screwdriver.

mounted on one surface of the carrier 132 by rails, embedding,
engaging, locking or adhesive, and it is not limited thereto. The
carrier 132 can be mounted on the bottom surface in the receptacle
103 of the base 101 of the housing 10 by screwing, locking or
engaging, and it is not limited thereto. By using the current-path
arrangement module 13, the bypass diodes 131a, 131b, 131c can be
replaced and maintained easily by replacing the current-path
arrangement module 13 with another one when one or more bypass
