Description
Technical field
The utility model relates to the local structure in a kind of solar panel junction box, specifically a kind of solar panel busbar fixed mechanism.
Background technology
Solar junction box is a kind of vitals in the field of solar thermal power generation, the main effect of terminal box couples together busbar and external circuitry exactly, has very high electricity requirement, require the stronger power of holding and the pressure force of adding, excellent conducting performance and arc protection performance, safe and reliable to guarantee that busbar connects.
Busbar fixed mechanism in the existing terminal box generally is by jump ring busbar to be fixed up, because it is fixing to rely on the elastic force of jump ring to realize fully, fixed effect is poor, and for guaranteeing the active force of jump ring, general very little with the gap design of clamping part position, fitting operation is very inconvenient.
As " a kind of solar junction box binding post " announced among the Chinese patent publication No. CN101847796, comprise binding post body and metal spring sheet, metal terminal is provided with the chevron inserting groove, during use, by screwdriver spring is pushed aside, the sheet that will conflux then inserts wherein, and extracting screwdriver out can be fixed up it.There is fixing illusive problem in the fixed form of this spring clamping connection, and because insufficient pressure is enough big, under the situation of sheet distortion of confluxing, the feasible problems such as sheet and the little and easy heating of binding post ontological existence contact resistance of confluxing, these have all had a strong impact on the security performance of the terminal box in the use.
The utility model content
At the drawback of the busbar fixed form of the good clamp connected of existing spring, the utility model provides a kind of solar panel busbar fixed mechanism, and is simple and reliable for structure, can realize the connection that busbar is safe and reliable; And operation is very easy, reduces the installing space of terminal box inside simultaneously.
The technical scheme in the invention for solving the technical problem is: this kind solar panel busbar fixed mechanism is characterized in that described busbar fixed mechanism is by the mode that fastens the busbar pressing and fixing to be got up.
Further, described busbar fixed mechanism comprises location division and pressing portion;
Described location division comprises substrate and the bus-bar that is installed on the substrate, and described bus-bar is the box-like body that tips upside down on the substrate, is sheet metal component; The bus-bar front portion is the cable installation portion, the middle part is the diode installation portion, there is a rectangular aperture at the rear portion, be used to locate busbar, two edges, front and back of described rectangular aperture are to doing down the circular arc in-flanges, described rectangular aperture the right and left extends upward trapezoidal picking up the ears along the place, and is provided with the technology breach at the circular arc in-flanges with between picking up the ears;
Described pressing portion comprises the pedestal of an insulation, described pedestal inboard is provided with a trapezoidal protrusion, the outside is for pressing closing operation portion, the metal jump ring of one " C " shape middle part by screw on the trapezoidal protrusion of pedestal, the circular arc flanging is outwards done at described metal jump ring two ends, and this flanging has identical curvature with circular arc in-flanges on the bus-bar.
Further, described base extension into strips, the other end has jointed shaft, can be hinged on the sidewall of substrate middle part.
Described base extension into strips, the other end has jointed shaft, can be hinged on the inwall of terminal box.
The beneficial effects of the utility model are:
1. fixed, because what adopt is the fixed form of buckle-type, more firm than traditional spring squash type, when fastening, busbar is extruded distortion, has changed to be subjected to force direction simultaneously.
2. easy to operate, during use, installation personnel need not hand and takes screwdriver, firmly gets final product by bottom base after only busbar need being put well the position, and is easy to operate.
3. improved electric property, conflux sheet and bus-bar contact area are bigger, and pressure is bigger, reduces the resistance value of contact position.

Fig. 2 is a upward view of the present utility model;
Fig. 3 is an A-A view profile among Fig. 1;
Fig. 4 is the pressing shape body schematic diagram of Fig. 3;
Fig. 5 is the B place partial enlarged drawing among Fig. 4.
Among the figure: 1 substrate, 2 bus-bars, 21 cable installation portions, 3 rectangular apertures, 31 in-flanges, 32 trapezoidal picking up the ears, 4 busbars, 5 pedestals, 51 trapezoidal protrusion, 52 stitching operation portions, 53 jointed shafts, 6 metal jump rings, 61 screws, 62 flange.
Embodiment
As Fig. 1～shown in Figure 5, this kind solar panel busbar fixed mechanism, described busbar fixed mechanism are by the mode that fastens the busbar pressing and fixing to be got up, and busbar fastens the position and bends in the process that fastens, and forms the knot shape, is difficult to come off.
Comprise location division and pressing portion.
The location division comprises substrate 1 and the bus-bar 2 that is installed on the substrate, totally four of the cylinder manifolds among the figure.Substrate 1 is an insulation board, as the mounting platform of miscellaneous part.Bus-bar 2 is sheet metal component for tipping upside down on the box-like body on the substrate 1, and bus-bar 2 front portions are cable installation portion 21, are used for being connected with the cable of electrical network; Middle part diode installation portion will couple together between the different bus-bars by diode; The rear upper end face has a rectangular aperture 3, is used to locate busbar 4, and two edges, front and back of rectangular aperture 3 are done circular arc in-flanges 31 downwards, makes busbar natural torsion in the process of pressing; Rectangular aperture 3 the right and lefts extend upward one and trapezoidally pick up the ears 32 along the place, be used for limiting the position of busbar, can improve installation effectiveness, because bus-bar is a sheet metal component, are integrated, so at circular arc in-flanges 31 with pick up the ears to be provided with between 32 the technology breach.
Pressing portion comprises the pedestal 5 of an insulation, and this pedestal is a moulding, is strip, is provided with a trapezoidal protrusion 51 in the inboard of pedestal one end, and the outside is a stitching operation portion 52, is that finger strength is made use; Be provided with jointed shaft 53 in pedestal 5 one end both sides, be hinged on the sidewall at substrate 1 middle part, at this moment, trapezoidal protrusion 51 is stuck in the rectangular aperture 3 just.Metal jump ring 6 middle parts of one " C " shape are fixed on the top of the trapezoidal protrusion 51 of pedestal by screw 61, reserve the certain elastic deformation space between metal jump ring and the trapezoidal protrusion two sides, metal jump ring 6 two ends are to circular arc flanging 62, and this flanging 62 has identical curvature with circular arc in-flanges on the bus-bar.During pressing, the rectangular aperture 3 on metal jump ring 6 and the bus-bar is jointly with busbar 4 compressive strains and pressing and fixing.
Described pedestal can be hinged on the inwall of terminal box, equally also can realize above-mentioned purpose.
Using method is: busbar is taken be placed on the rectangular aperture top, because there is trapezoidal position-limiting action of picking up the ears the both sides of rectangular indentation, takes and put easily.Stir pedestal with finger, and firmly press in the stitching operation portion of pedestal, the side busbar will be crushed out of shape, and this distortion just in time launches along the just face of metal jump ring, is dragging under the situation of busbar, and busbar also is difficult to come off from the pressing position, and is fool proof reliable; Simultaneously, because the pressure force at pressing position is far longer than traditional spring clamping force, so the fitting area that confluxes between sheet and the bus-bar also is very big.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; this area person skilled all should expand as in the determined protection range of the utility model claims various distortion of the present utility model and improvement.
