Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic testing and detection, and in particular to a flexible energized testing component. Background Art

[0002] During the production process of photovoltaic modules, in order to achieve efficiency grading of photovoltaic modules, it is necessary to use a power-on test fixture and a power-on test component assembled on the power-on test fixture to perform power testing on the photovoltaic modules (that is, to test the IV characteristics of the cells in the photovoltaic modules) to detect a series of electrical performance parameters such as the open-circuit voltage, power, and series resistance of the cells in the photovoltaic modules.

[0003] The existing power-on test of photovoltaic modules generally uses the Kelvin test method using four copper sheets. During the test, the two sockets of the photovoltaic module are respectively inserted into the positive / negative plugs on the power-on test module, and then the four copper sheets are closely contacted with the four probes on the power tester to reduce the impact of changes in contact resistance between the probes and the four copper sheets on the power-on test module on the test power of the photovoltaic module.

[0004] However, the copper sheet of the prior art power-on test assembly is connected to the positive / negative plugs through an electrical test cable, which makes the power-on test assembly susceptible to the resistance of the electrical test cable, thereby reducing the accuracy of the power-on test assembly in detecting the power of the photovoltaic assembly. In addition, the current power-on test assembly can usually only be connected to the photovoltaic assembly in one direction, but in actual testing, there may be situations where the installation position is inconvenient to connect or measurement cannot be performed, resulting in the existing power-on test assembly being unable to meet the connection requirements of the photovoltaic assembly installation direction, which can easily affect the accuracy of the photovoltaic assembly test results.

[0005] Based on the above defects and deficiencies, it is necessary to improve the components used for power-on testing of photovoltaic modules in the prior art to solve the above problems. Summary of the Invention

[0006] In response to the above problems, the present invention provides a flexible power-on test component that is easy to operate and can not only reduce the resistance influence from the power-on test cable, but also meet the connection requirements of photovoltaic components in different directions and positions, thereby improving the accuracy of test results.

[0007] The technical solution is as follows: a flexible power-on test component, including a mounting base, a conductor mounted on the mounting base and electrically connected to a probe, and a conductive head connected to a photovoltaic component, characterized in that: the mounting base has a mounting cavity and an auxiliary cavity located around the mounting cavity, the mounting cavity and the auxiliary cavity are both equipped with the conductive head, and the mounting cavity and the auxiliary cavity are interconnected so that the conductive heads in the mounting cavity and the auxiliary cavity are in contact with each other, and the mounting base also has at least one circuit path for forming an interconnection between the conductor and one of the conductive heads.

[0008] It is further characterized by:

[0009] The mounting base is formed into an L-shaped structure by a vertical section and a horizontal section connected as a whole and forming a right angle with each other;

[0010] The installation cavity is formed inside the vertical section, and the auxiliary cavity is formed on the side end of the vertical section; the conductor is assembled on the top of the horizontal section;

[0011] The conductive body and the conductive head are interconnected via a conductive member, which sequentially passes through the conductive body and the mounting seat and then extends along the circuit path until it is connected to one of the conductive heads;

[0012] The conductive head has a positive and negative pole, and is divided into a main conductive head and an auxiliary conductive head. The mounting portion of the main conductive head is assembled in the mounting cavity, and the mounting portion of the auxiliary conductive head is assembled in the auxiliary cavity.

[0013] The mounting portion of the auxiliary conductive head and the inner wall of the auxiliary cavity are provided with corresponding threads, and the mounting portion of the auxiliary conductive head is screwed into the auxiliary cavity until it contacts and connects with the mounting portion of the main conductive head;

[0014] The mounting seat is provided with an elastic clamping member, which comprises a connecting section, a clamping section, and a guide section which are sequentially connected and integrated; the connecting section is located above the mounting cavity and is connected to the inner side wall of the vertical section; a clamping area is formed between the clamping section and the bottom surface of the horizontal section; the guide section is bent away from the horizontal section;

[0015] The end of the horizontal section is an inclined structure; there is a distance between the clamping section and the bottom surface of the horizontal section, and the distance gradually decreases along the extension direction of the horizontal section;

[0016] A groove is provided on the bottom surface of the horizontal section, and an anti-slip strip is installed in the groove. The thickness of the anti-slip strip is greater than the depth of the groove, so that part of the anti-slip strip is exposed on the bottom surface of the horizontal section;

[0017] The material of the anti-off strip is any one of silica gel, latex, and rubber.

[0018] The beneficial effect of the present application is that the electrically conductive body and the electrically conductive head are connected by the circuit path on the mounting seat to form a circuit interconnection, which can effectively reduce the resistance influence from the power-on test cable, and the electrically conductive head in the mounting cavity and the electrically conductive head in the auxiliary cavity are in contact, so that the connection of the photovoltaic module in different directions can be met according to the use condition, thereby improving the accuracy of the power detection of the photovoltaic module by the power-on test assembly, and the installation operation is relatively simple, and has good economic use value.

The flexible power-on test assembly is mounted on a corresponding test tool (not shown in the figure) to realize the power test of the photovoltaic module. The electrically conductive body 2 and the electrically conductive head are connected to establish a signal circuit path of the detection data, and then the probe on the power tester (not shown in the figure) is connected with the electrically conductive body 2 to perform the power test.

[0025] The mounting seat 1 has a mounting cavity 3 and an auxiliary cavity 4 located around the mounting cavity 3. The auxiliary cavity 4 can be arranged at different direction positions of the mounting seat 1 according to the condition, so that the electrically conductive head in the auxiliary cavity 4 can be in contact with the electrically conductive head in the mounting cavity 3. The mounting cavity 3 and the auxiliary cavity 4 are both provided with the electrically conductive head, and the mounting cavity 3 and the auxiliary cavity 4 are mutually penetrated, so that the electrically conductive head in the mounting cavity 3 and the electrically conductive head in the auxiliary cavity 4 are in contact. The mounting seat 1 is further provided with at least one circuit path (not shown in the figure) for forming the interconnection between the electrically conductive body 2 and one of the electrically conductive heads.

[0026] The mounting seat 1 is an L-shaped structure consisting of a vertical section 5 and a horizontal section 6 connected as a whole at right angles to each other; the mounting cavity 3 is formed on the inner side of the vertical section 5, and the auxiliary cavity 4 is formed on the side end of the vertical section 5; the conductor 2 is assembled on the top of the horizontal section 6.

[0027] The conductor 2 and the conductive head are interconnected through a conductive part (not shown in the figure). Screw holes 7 are provided in the conductive part and its corresponding mounting seat 1. The conductive part passes through the screw hole 7, the conductor 2, and the mounting seat 1 in sequence and then extends along the circuit path until it is connected to one of the conductive heads. It should be noted that the conductive part can be a columnar metal part such as a bolt to achieve electrical signal conduction; the conductor 2 is made of copper sheet.

[0028] The conductive head has positive and negative poles, and the male and female forms of the conductive head can be set according to the situation. The conductive head is divided into a main conductive head 8 and an auxiliary conductive head 9. That is, when the conductive head is a positive polarity conductive head, the main conductive head 8 and the auxiliary conductive head 9 are both positive polarity connector structures, and the connection ends of the main conductive head 8 and the auxiliary conductive head 9 are both male heads. When the conductive head is a negative polarity conductive head, the main conductive head 8 and the auxiliary conductive head 9 are both negative polarity connector structures, and the connection ends of the main conductive head 8 and the auxiliary conductive head 9 are both female heads.

[0029] In the embodiment of the present invention, the auxiliary conductive head 9 is a columnar structure. The mounting portion of the main conductive head 8 is directly embedded in the mounting cavity 3, and the mounting portion of the auxiliary conductive head 9 is assembled in the auxiliary cavity 4. Specifically, the mounting portion of the auxiliary conductive head 9 and the inner wall of the auxiliary cavity 4 are provided with corresponding threads. The mounting portion of the auxiliary conductive head 9 is screwed into the auxiliary cavity 4 until it contacts and connects with the mounting portion of the main conductive head 8.

[0030] Furthermore, the auxiliary conductive head 9 can also be a right-angle structure (not shown in the figure). The mounting part of the auxiliary conductive head 9 is directly inserted into the auxiliary cavity 4 and contacted and connected with the mounting part of the main conductive head 8. After the mounting part of the auxiliary conductive head 9 is inserted into the auxiliary cavity 4, it can be freely rotated to change the direction of the connection end of the auxiliary conductive head 9, and can also adapt to the connection and use of photovoltaic components in different directions.

[0031] The mounting seat 1 is provided with an elastic clamping member 10, which can be made of an elastic stainless steel sheet, and the elastic stainless steel sheet includes a connecting section 11, a clamping section 12 and a guide section 13 which are connected in sequence as an integral whole; the connecting section 11 is located above the mounting cavity 3, and is connected to the inner wall of the vertical section 5 by bolts; a clamping area is formed between the clamping section 12 and the bottom surface of the horizontal section 6; the guide section 13 is bent away from the horizontal section 6, and the end of the horizontal section 6 is a sloped structure, which can facilitate guided installation; there is a distance between the clamping section 12 and the bottom surface of the horizontal section 6, and the distance gradually decreases along the extension direction of the horizontal section 6 to facilitate clamping.

[0032] The horizontal section 6 is provided with a groove 14 in the bottom surface, and an anti-dropping strip (not shown in the figure) is arranged in the groove 14, the thickness of the anti-dropping strip is greater than the depth of the groove 14, so that part of the anti-dropping strip is exposed on the bottom surface of the horizontal section 6; the material of the anti-dropping strip is any one of silica gel, latex and rubber material, and the latex material is preferred, which can effectively prevent slipping and falling off.

[0033] In the testing process, the electric conductor 2 and the electric head are connected through the circuit path formed on the mounting seat 1 and the conducting part, and the circuit interconnection is directly carried out, so that the influence of the existing resistance from the power testing cable can be effectively reduced, and the electric conductor 2 is connected with the main electric head 8 or the auxiliary electric head 9, so that the power test can be realized, and the connection and use of the photovoltaic module in different directions and positions can be met according to the installation condition, so that the accuracy of the power detection of the photovoltaic module by the power testing assembly is improved, and the installation operation is relatively simple.

Thus, the present embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the description given above, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
