[0001] This utility model relates to the field of contactor processing technology, specifically to an integrated DC high-voltage contactor assembly and processing auxiliary device. Background Technology

[0002] In fields such as new energy vehicles, energy storage systems, and rail transit, integrated DC high-voltage contactors serve as core power control components, undertaking the crucial function of connecting or disconnecting high-voltage DC circuits. Their performance stability and assembly precision directly determine the safe operation and energy efficiency level of the entire power system.

[0003] The assembly and processing of integrated DC high-voltage contactors involves the assembly of multiple precision components such as contact assemblies, coil windings, insulating shells, and terminals. However, existing assembly and processing methods are still mainly manual, supplemented by simple tooling fixtures, which have low adaptability. When assembling and processing at different workstations, different types of tooling fixtures are required to hold one or more contactor shells for assembly and processing, which requires repeated disassembly and assembly, which is time-consuming and labor-intensive, and can easily damage the contactor during the assembly process, thus affecting the overall assembly and processing efficiency. To address these issues, we propose an integrated DC high-voltage contactor assembly and processing auxiliary device. Utility Model Content

[0023] Example: Figure 1-5As shown, this utility model provides an integrated DC high-voltage contactor assembly and processing auxiliary device, including a positioning component 1. The positioning component 1 has multiple components arranged in a rectangular array. The positioning component 1 includes a first half-frame 2 and a second half-frame 3. A first inner fixing block 4 is movably engaged on the inner wall of the first half-frame 2 away from the second half-frame 3. A second inner fixing block 5 is movably engaged on the inner wall of the second half-frame 3 away from the first half-frame 2. A receiving groove 302 is opened in the middle of the side of the second half-frame 3 away from the first half-frame 2. An inner screw cylinder 6 is fixedly engaged at the inner end of each receiving groove 302. A fastening screw 61 is threadedly installed in the middle of the inner screw cylinder 6. An inner groove 501 corresponding to the fastening screw 61 is opened on the side of the second inner fixing block 5 away from the first inner fixing block 4. The fastening screw 61... The end of the positioning component 1 extends into the second half-frame 3 and is movably engaged in the inner groove 501. The four corners of the positioning component 1 are fixedly fitted with inner threaded sleeves 7. The middle of the inner threaded sleeves 7 is threaded with a support screw 71. By setting the support screw 71, the first half-frame 2 and the second half-frame 3 are supported, thereby supporting the positioning contactor outer frame and preventing the bottom of the contactor outer frame from contacting the workbench. The height of the first half-frame 2 and the second half-frame 3 can be flexibly adjusted according to the height of the contactor outer frame to support the contactor outer frame. The outer side of the positioning component 1 is provided with two sets of L-shaped brackets 8. The two sets of L-shaped brackets 8 are respectively fixedly installed on the adjacent side ends of the outer wall of the positioning component 1. The side of the outer wall of the positioning component 1 away from the L-shaped brackets 8 is provided with an L-shaped slot 801.

[0024] Two adjacent positioning parts 1 are movably engaged in the corresponding L-shaped slots 801 through L-shaped brackets 8. By setting L-shaped brackets 8 and opening L-shaped slots 801, it is convenient to engage and install two adjacent positioning parts 1, so as to facilitate the positioning and assembly of a suitable number of positioning parts 1 according to the needs of different workstations, and to assist in the positioning of a corresponding number of contactor frames, so as to assemble and process multiple contactors and improve the assembly efficiency of contactors.

[0025] A first protective pad 41 is fixedly provided on the side of the first inner fixing block 4 near the second inner fixing block 5, and a second protective pad 51 is fixedly provided on the side of the second inner fixing block 5 near the first inner fixing block 4. By setting the first protective pad 41 and the second protective pad 51, the outer shell of the contactor is prevented from being scratched when it is assisted in positioning.

[0026] Both ends of the first inner fixing block 4 are integrally formed with a first locking protrusion 42. The inner wall of the first half frame 2 is provided with a first locking groove 201 corresponding to the first locking protrusion 42. The first locking protrusion 42 is movably engaged in the first locking groove 201 to perform the locking of the first inner fixing block 4, thereby facilitating the selection and installation of the corresponding first inner fixing block 4 according to the shape of the contactor outer frame.

[0027] The two ends of the second inner fixing block 5 are integrally formed with a second locking protrusion 52. The inner wall of the second half frame 3 is provided with a second locking groove 301 corresponding to the second locking protrusion 52. The second locking protrusion 52 is movably engaged in the second locking groove 301 to perform the locking of the second inner fixing block 5, thereby facilitating the selection and installation of the corresponding second inner fixing block 5 according to the shape of the contactor outer frame.

[0028] The first half-frame 2 has a connecting protrusion 21 integrally formed at one end near the second half-frame 3. The connecting protrusion 21 is movably engaged with the end of the second half-frame 3 near the first half-frame 2. A connecting bolt 23 is threadedly installed at the end of the second half-frame 3 near the first half-frame 2. The end of the connecting bolt 23 is threadedly installed on the connecting protrusion 21. The connecting protrusion 21 has a positioning protrusion 22 integrally formed at the end away from the first half-frame 2. The positioning protrusion 22 is movably engaged in the corresponding second slot 301 to fix the first half-frame 2 and the second half-frame 3.

[0029] Working principle: When it is necessary to assemble and process the components in the contactor separately, firstly, according to the shape of the contactor outer frame, select and install the corresponding first inner fixing block 4 on the inner wall of the first half frame 2, and select and install the corresponding second inner fixing block 5 on the inner wall of the second half frame 3, and use connecting bolts 23 to fix the first half frame 2 and the second half frame 3. Then, according to the height of the contactor outer frame, install the adjusting support screw 71 to adjust the height of the first half frame 2 and the second half frame 3.

[0030] Subsequently, the contactor outer frame is placed between the first inner fixing block 4 and the second inner fixing block 5. The fastening screw 61 is rotated so that the end of the fastening screw 61 extends into the second half frame 3 and is movably engaged in the inner groove 501, abutting against the second inner fixing block 5. The first inner fixing block 4 and the second inner fixing block 5 assist in positioning the contactor outer frame so that the components in the contactor can be assembled and processed individually and stably.

[0031] When the contactors need to be encapsulated together in the future, it is not necessary to disassemble each contactor frame separately and install it on an appropriate multi-point positioning plate for subsequent encapsulation. Instead, two adjacent positioning pieces 1 are simply engaged in the corresponding L-shaped slots 801 via L-shaped brackets 8. This allows for the easy positioning and assembly of a suitable number of positioning pieces 1 according to requirements, which can then be used to assist in the positioning of the corresponding number of contactor frames. This facilitates the subsequent encapsulation of multiple contactors and improves the assembly efficiency of the contactors.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
