Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic cell testing, in particular to a photovoltaic component probe row. Background Art
[0002] Photovoltaic modules are usually composed of cells with similar electrical properties. Obtaining the electrical properties of cells through IV testing is the main means of sorting and packaging cells. In addition, IV testing can also evaluate the open circuit voltage, short circuit current, fill factor and conversion efficiency of cells, which are of great significance to the quality of cells.
[0003] Probe rows play a key role in IV testing. They measure the voltage and current of the cell by fixing them on the fixture of the IV test equipment. Traditional probe rows are usually realized by connecting the probes using copper strips or tinned copper tapes on an insulating substrate.

When testing cells with different grid specifications or processes, different probe rows and fixtures need to be replaced, and even customized designs may be required, which will greatly increase production time and production costs.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0035] See also Figure 1 and Figure 2The embodiment of the present application provides a photovoltaic module probe 2 row, including a mounting member 1, a plurality of probes 2, a locking structure 3 and a plurality of limiting structures 4. The locking structure 3 is used to lock the relative position of the probe 2 and the mounting member 1 in the length direction. The limiting structure 4 is used to limit the relative position of the probe 2 and the mounting member 1 in the height direction in a one-to-one manner.
[0036] Specifically, the mounting member 1 includes two detachably mounted mounting plates 11, the two mounting plates 11 enclose a mounting cavity 5, the mounting cavity 5 penetrates the mounting member 1 along the height direction, and the mounting member 1 also includes an operation hole 6, the operation hole 6 penetrates the mounting member 1 along the thickness direction and is connected to the mounting cavity 5. A welding point 7 for welding a wire is provided on the outer side wall of at least one mounting plate 11.
[0037] It should be noted that the height direction is Figure 1 As shown by the arrow a in the middle, the length direction is Figure 1 As shown by arrow b in the middle, the thickness direction is Figure 1 As shown by arrow c.
[0038] In some embodiments, the two mounting plates 11 are fixed by threaded fasteners 9 , and countersunk holes 12 for mounting the threaded fasteners 9 are symmetrically arranged on the two mounting plates 11 .
[0039] A plurality of probes 2 are slidably disposed in the mounting cavity 5 along the height direction, and are configured to be slidable relative to the mounting member 1 in the length direction.
[0040] The locking structure 3 is located above the operating hole 6 , and includes a first locking portion and a second locking portion that match each other. The first locking portion is arranged on the inner side wall of at least one mounting plate 11 , and the second locking portion is arranged on the probe 2 .
[0041] In some embodiments, the first locking portion is a locking groove 31 formed by being recessed inward from the inner side wall of the mounting plate 11, and a plurality of saw teeth are arranged at equal intervals along the length direction in the locking groove 31, and a tooth groove is formed between two adjacent saw teeth. The second locking portion is a locking block 34 inserted into the locking groove 31, and the shape of the locking block 34 is adapted to the shape of the tooth groove, and the diameter of the probe 2 is larger than the groove width of the tooth groove.
[0042] In some embodiments, the first locking portion also includes a clearance groove 35, which is arranged between the operating hole 6 and the locking groove 31. The clearance groove 35 is formed by being recessed inward from the inner wall of the mounting plate 11, and the groove depth of the clearance groove 35 is greater than the thickness of the locking block 34.
[0043] The limiting structure 4 and the probe 2 are arranged in a one-to-one relationship in the operating hole 6 and are configured to at least actuate the probe 2 to move downward in the height direction under the action of an external force so as to unlock the corresponding second locking portion and the first locking portion.
[0044] In some embodiments, the limiting structure 4 includes an upper plate 41 fixed on the probe 2, a lower plate 42 slidably mounted on the probe 2 and located below the upper plate 41, and an elastic reset member 43 connected between the upper plate 41 and the lower plate 42.
[0045] The axis of the probe 2, the center line of the upper plate 41 and the center line of the lower plate 42 are collinear. The lengths of the upper plate 41 and the lower plate 42 are greater than the depth of the operating hole 6. The elastic reset member 43 is always in a compressed state.
[0046] After assembly, under the elastic force of the elastic reset member 43, the upper plate 41 and the lower plate 42 have a tendency to move away from each other. Since the lengths of the upper plate 41 and the lower plate 42 are greater than the depth of the operation hole 6, the upper plate 41 is pressed against the top surface of the operation hole 6, and the lower plate 42 is pressed against the bottom surface of the operation hole 6, so that the limiting structure 4 is clamped in the operation hole 6 to limit the movement of the probe 2 in the height direction relative to the mounting member 1. At this time, the locking block 34 is inserted into the tooth groove at the corresponding position, thereby limiting the movement of the probe 2 in the length direction relative to the mounting member 1.
[0047] When adjusting the position of the probe 2, the upper plate body 41 is moved toward the lower plate body 42 through external force. Since the upper plate body 41 and the probe 2 are fixed, the probe 2 is driven to move downward, and the locking block 34 is driven to move in the height direction relative to the tooth groove, so that the two are unlocked, and the locking structure 3 no longer restricts the movement of the probe 2 in the length direction relative to the mounting member 1. The position of the probe 2 is adjusted along the length direction, and the external force is removed. The upper plate body 41 drives the probe 2 to reset under the elastic force of the elastic reset member 43, and the locking block 34 is inserted into the tooth groove at the corresponding position and locked.
[0048] In some embodiments, the upper plate 41 is threadedly connected to the probe 2, and a thread segment 8 is axially arranged on the probe 2, so that the fixed position of the upper plate 41 and the probe 2 in the height direction is adjustable to be suitable for cells with different surface heights or curved cells.
[0049] In some embodiments, the number of the elastic reset members 43 is two, and in the thickness direction of the mounting member 1 , the two elastic reset members 43 are symmetrically arranged on both sides of the corresponding probe 2 .
[0050] In some embodiments, the elastic reset member 43 includes a telescopic rod and a spring sleeved on the outside of the telescopic rod.
[0051] In other embodiments, the elastic return member 43 is an elastic sheet obliquely disposed between the upper plate 41 and the lower plate 42 .
[0052] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
