Abstract
The utility model discloses a junction box sharing welding spots, which comprises a diode component, wherein the diode component consists of a diode, two conducting plates and two bus bars, the two conducting plates are respectively welded with two pins of the diode, the two conducting plates are respectively welded with one bus bar, and each conducting plate is welded with the pin of the diode and the bus bar at the same welding spot. The utility model combines two originally separated welding spots into one welding spot, thus reducing the number of the welding spots and the usage amount of the welding flux; the short edge of the side edge of the main body is connected with the main body and has certain deflection, and in an initial state, the short edge is in a warping state, so that the diode pin can be conveniently placed in the U-shaped bent groove, and then the short edge is flattened to press the diode pin, so that the diode is prevented from deflecting.
Description
Technical Field
The utility model belongs to the technical field of solar cells, and particularly relates to a junction box for a solar cell, in particular to a junction box sharing welding spots.
Background
The junction box is an essential component in a solar cell module, and is used for collecting and transmitting current generated by a silicon wafer. There are several different types and configurations of terminal blocks available to meet the needs of different battery packs. The core part of the junction box is a diode component which comprises a diode, two conducting strips which are respectively and electrically connected with pins at two ends of the diode, and a bus bar which is welded on the conducting strips. It can be seen that there are four solder joints on each diode assembly, i.e., two conductive pads are soldered to the diode pins and the bus bar, respectively.
Disclosure of Invention
The utility model aims to provide a junction box sharing welding points so as to reduce the number of the welding points in the junction box.
Therefore, the technical scheme adopted by the utility model is as follows: the utility model provides a terminal box of sharing solder joint, includes diode subassembly, and diode subassembly comprises diode, two conducting strips, two bus bars, and two conducting strips weld with two pins of diode respectively, and two conducting strips weld a bus bar, its characterized in that respectively: and each conducting sheet is welded with a diode pin and a bus bar at the same welding point.
Furthermore, the main body of the conducting strip is provided with a U-shaped bend, and the diode pin is placed in a groove formed by the U-shaped bend; and a long hole for the bus bar to pass through is formed in one side edge of the U-shaped bend, and the bus bar passes through the long hole and then covers the diode pin and is welded into a whole.
Furthermore, the conducting strip is arranged outside the U-shaped bent main body and is provided with a short side which is formed by punching and connected with the main body.
The utility model combines two originally separated welding spots into one welding spot, thus reducing the number of the welding spots and the usage amount of the welding flux; the short edge of the side edge of the main body is connected with the main body and has certain deflection, and in an initial state, the short edge is in a warping state, so that the diode pins can be conveniently placed in the U-shaped bending grooves, and then the short edge is flattened to press the diode pins and prevent the diodes from deflecting.

Detailed Description
See the drawings. This embodiment includes box body 1, has the diode subassembly in the box body. The diode component comprises a negative conductive sheet 2, a diode 3, a solder 4, a positive conductive sheet 5 and a bus bar 6, wherein the negative conductive sheet 2 and the positive conductive sheet 5 are symmetrical, and only the negative conductive sheet 2 is taken as an example. The main body part of the bus bar is provided with a U-shaped bend 21, and one side edge of the U-shaped bend is provided with a long hole 22 for the bus bar to pass through; there are also two punched short sides 23 outside the U-bend, the short sides 23 being warped in the initial state. And respectively putting the positive pin and the negative pin of the diode 3 into the U-shaped bending of the positive conducting plate and the negative conducting plate, flattening the short side to fix the diode, and then applying the solder 4 to weld, namely, the junction box is completed in stages. After the junction box is assembled on the solar cell, the bus bar 6 penetrates out of the long hole, is guided to the pin of the diode, and the bus bar can be welded on the same welding point by melting the welding flux again.
