Description

Technical Field

[0001] This utility model relates to the field of photovoltaic testing technology, specifically to a photovoltaic test probe array. Background Technology

[0002] Photovoltaic testing, also known as solar photovoltaic testing, refers to laboratory and outdoor testing conducted by the photovoltaic industry to verify whether the final performance of products, raw materials, processes, and power plants meets industry standards, according to prescribed methods and procedures. For example, crystalline silicon modules use polycrystalline silicon, solar cells, silver paste, backsheets, glass, encapsulation materials, etc., all of which require testing of their raw materials and finished products.

[0003] Currently, in the precision testing process of the photovoltaic industry, the existing base frame for supporting test probes is usually fastened to the equipment bracket with bolts. The bolt connection requires multiple tightening operations with special tools. The disassembly of a single probe array is time-consuming and cumbersome, which greatly affects work efficiency and results in poor performance. Therefore, this application proposes a photovoltaic test probe array to solve the above-mentioned shortcomings. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic test probe array. By setting a connecting seat, a locking block, and a locking slot between the mounting base and the connecting frame, and with the cooperation of structures such as the cavity, movable block, positioning post, and positioning hole, after the locking block and the locking slot are inserted and engaged, the two movable blocks are controlled to move closer to each other by a moving mechanism. This allows the movable block to drive the positioning post to be inserted and engaged in the positioning hole, thereby locking the locking block in the locking slot. This achieves the fastening of the connecting frame on the mounting base. Conversely, the connecting frame can be removed from the mounting base, which facilitates the disassembly, assembly, and maintenance of the test probe. The operation is simple and convenient, and the use effect is good, thus solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic test probe array, comprising: Mounting base, the bottom side of which is detachably connected to a connecting base, the bottom side of which is fixed to a connecting frame, and the bottom side of which is connected to multiple test probes, the top of which is connected to a wire; A locking block is fixed in the middle of the top side of the connecting seat, and a slot is provided in the middle of the bottom side of the mounting seat, and the locking block can be inserted into the slot. The cavity is located inside the mounting base, and movable blocks are symmetrically arranged at both ends of the cavity. Positioning posts are fixed at the bottom of the side walls of the two movable blocks, and one end of the positioning post extends into the slot. Positioning holes matching the positioning posts are opened at both ends of the slot. A moving mechanism, mounted on a mounting base, is used to drive two movable blocks to move toward or away from each other.

[0006] Preferably, the moving mechanism includes a bidirectional screw rotatably connected to the cavity through a bearing, and the two movable blocks are respectively screwed to both ends of the bidirectional screw, with one end of the bidirectional screw extending outside the mounting base and fixed with a rotating handle.

[0007] Preferably, the mounting base has fixing plates at both ends of its top end, and the fixing plates have fixing holes on their side walls.

[0008] Preferably, the connecting frame has a U-shaped structure, and the bottom side of the connecting frame is provided with multiple hollow grooves.

[0009] Preferably, the mounting base has symmetrically arranged screw holes at both ends of its top side, and a stud is connected through the screw hole. A fixing block is fixed to the top of the stud, and the bottom of the stud extends into the cavity and is movably connected to a pressure block through a bearing. The inner side of the pressure block is provided with anti-slip ridges facing the bidirectional screw.

[0010] Preferably, both ends of the pressure block are fixed with limit posts, and the inner wall of the cavity is provided with a limit groove that matches the limit posts.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By setting a connecting seat, a locking block, and a locking slot between the mounting base and the connecting frame, and with the cooperation of structures such as the cavity, movable block, positioning post, and positioning hole, after the locking block and the locking slot are inserted and engaged, the two movable blocks are controlled to move closer to each other by the moving mechanism. This allows the movable block to drive the positioning post to be inserted and engaged in the positioning hole, thereby locking the locking block in the locking slot. This achieves the fastening of the connecting frame on the mounting base. Conversely, the connecting frame can be removed from the mounting base, which facilitates the disassembly, assembly, and maintenance of the test probe. The operation is simple and convenient, and the effect is good. By setting up structures such as fixing blocks, studs, and pressure blocks, the pressure blocks can be lowered and pressed against the outer wall of the bidirectional screw, thereby further locking and fixing the bidirectional screw. This effectively prevents the movable block from moving, thus greatly ensuring the stability of the connection between the connecting frame and the mounting base. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figures 1-5 A photovoltaic test probe array shown includes: Mounting base 1, with a connecting base 5 detachably connected to the bottom side of mounting base 1, a connecting bracket 3 fixed to the bottom side of connecting base 5, and multiple test probes 4 passing through the bottom side of connecting bracket 3, with wires connected to the top of test probes 4. The mounting base 1 has fixing plates 2 at both ends of its top, and fixing holes are provided on the side walls of the fixing plates 2. Based on this, the device can be fixedly installed through the fixing plates 2.

[0017] The connecting frame 3 has a U-shaped structure, and multiple hollow slots are provided on the bottom side of the connecting frame 3. Based on this, the weight of the component can be greatly reduced through the hollow slots.

[0018] A locking block 6 is fixed in the middle of the top side of the connecting seat 5, and a slot 7 is provided in the middle of the bottom side of the mounting seat 1, and the locking block 6 can be inserted into the slot 7. The cavity 8 is located inside the mounting base 1, and movable blocks 9 are symmetrically arranged at both ends of the cavity 8. Positioning posts 10 are fixed at the bottom of the side walls of the two movable blocks 9, and one end of the positioning post 10 extends into the slot 7. Positioning holes 11 matching the positioning posts 10 are opened at both ends of the slot 6. The moving mechanism, located on the mounting base 1, is used to drive the two movable blocks 9 to move towards or away from each other.

[0019] In use, the card block 6 can be inserted into the slot 7 to initially connect the connecting seat 5 and the mounting seat 1. Then, the moving mechanism can be operated to control the two movable blocks 9 to move closer to each other. After that, the movable block 9 can drive the positioning pin 10 to extend out of the cavity 8 and enter the slot 7. Then, the positioning pin 10 can be inserted into the positioning hole 11 on the card block 6, thereby locking the card block 6 in the slot 7, thus achieving the fastening of the connecting frame 3 on the mounting seat 1. Conversely, the connecting frame 3 can be removed from the mounting seat 1, which facilitates the disassembly, assembly, maintenance, and testing of the probe 4. The operation is simple and convenient, and the effect is good.

[0020] The moving mechanism includes a bidirectional screw 12 rotatably connected to the cavity 8 via bearings. Two movable blocks 9 are screwed to both ends of the bidirectional screw 12. One end of the bidirectional screw 12 extends outside the mounting base 1 and is fixed with a handle 13. By turning the handle 13, the handle 13 can drive the bidirectional screw 12 to rotate. Then, under the action of the threads, the bidirectional screw 12 can drive the two movable blocks 9 to slide towards or away from each other in the cavity 8, so that the movable blocks 9 can drive the two positioning pins 10 to move closer or further away from each other.

[0021] The mounting base 1 has symmetrical screw holes 14 at both ends of its top side. A stud 15 is connected through the screw hole 14. A fixing block 16 is fixed to the top of the stud 15, and the bottom of the stud 15 extends into the cavity 8 and is movably connected to a pressure block 17 through a bearing. The inner side of the pressure block 17 is provided with anti-slip ridges facing the bidirectional screw 12.

[0022] By turning the fixing block 16, the fixing block 16 can drive the stud 15 to move in the screw hole 14. Then the stud 15 can drive the pressure block 17 to move, so that the pressure block 17 descends and presses against the outer wall of the bidirectional screw 12. Under the action of the two sets of pressure blocks 17, the bidirectional screw 12 can be further locked and fixed, thereby effectively preventing the movable block 9 from moving, and thus greatly ensuring the stability of the connection between the connecting frame 3 and the mounting base 1.

[0023] Both ends of the pressure block 17 are fixed with limit posts 18, and the inner wall of the cavity 8 is provided with a limit groove 19 that matches the limit posts 18. Based on this, by setting the limit posts 18 and the limit groove 19, the pressure block 17 can drive the limit posts 18 to slide along the limit groove 19, thereby making the pressure block 17 rise and fall stably in a straight line.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
