Description

Technical Field

[0001] The utility model relates to the technical field of contactors, in particular to an auxiliary moving spring assembly structure. Background Art

[0002] In addition to the main contacts, existing high-voltage DC contactors usually also have auxiliary contacts, which are used as auxiliary logic switches for the circuit control system to judge the working state of the contactor and monitor the adhesion failure of the main circuit contacts.

[0003] The auxiliary moving spring pieces of existing high-voltage DC contactors are in sheet form. During frequent contact with the terminals, if not properly fixed, the auxiliary moving spring pieces are likely to fall off, losing the monitoring function for the main circuit contacts.

[0004] For example, a Chinese invention patent with the publication number CN118299230A discloses a ceramic high-voltage DC contactor with an auxiliary contact circuit structure, which includes an insulating housing, an operating component, an auxiliary contact piece component, a metal shell, and a ceramic cover arranged inside the insulating housing. By setting the auxiliary moving spring piece structure to be similar to a "semicircular" arc surface, the auxiliary moving spring piece and the auxiliary static spring piece have stable stress points and reliable contacts; the first auxiliary terminal is fixedly connected to the auxiliary moving spring piece; the second auxiliary terminal is fixedly connected to the auxiliary static spring piece; so that during operation, there is a stable connection between the second auxiliary terminal and the first auxiliary terminal, which is fixed by brazing to form an auxiliary contact circuit. The auxiliary moving spring piece and the auxiliary static spring piece are installed on the upper part of the moving contact piece, which can isolate the ablation and coverage of the auxiliary circuit by the arc, metal droplets, etc. generated by the high-power main circuit, and ensure the insulation of the auxiliary circuit. By setting the upper armature and the lower armature to be separated, a suspended anti-repulsion magnetic circuit is formed, which can conveniently adjust the gap between them.

[0005] In the above solution, the auxiliary moving spring piece is fixedly connected to the auxiliary terminal by brazing. The terminal needs to be inserted and then welded, which is inconvenient for assembly. Moreover, the welding area between the two is small, and most of the auxiliary moving spring piece is suspended inside the contactor, so there is a risk of the auxiliary moving spring piece falling off during frequent contact with the terminal.

[0038] As Figures 1 to 9An auxiliary dynamic spring assembly structure shown in the figure includes an auxiliary dynamic spring assembly, a mounting plate 1 and a limit assembly, wherein the auxiliary dynamic spring assembly includes an auxiliary dynamic spring seat 2 and an auxiliary dynamic spring sheet 3 mounted on the auxiliary dynamic spring seat 2; the auxiliary dynamic spring seat 2 includes a bottom block 4 and a mounting block 5 formed on the upper end of the bottom block 4, the mounting block 5 includes an intermediate block 6 and protective blocks 7 formed on both sides of the intermediate block 6, a protective groove 8 is constructed on the protective block 7, and an inserting hole 9 is constructed laterally on the inner side of the intermediate block 6, and the inserting hole 9 extends to the protective blocks 7 on both sides and communicates with the protective groove 8;

[0039] The auxiliary spring 3 is inserted into the insert hole 9, and includes a connecting portion positioned in the insert hole 9 and a contact portion formed on both sides of the connecting portion and extending in the protective groove 8. The connecting portion is provided with a connecting hole 10, and the intermediate block 6 is provided with a positioning hole 11 corresponding to the connecting hole 10 and communicating with the insert hole 9;

[0040] A slide groove 12 is constructed at the lower end of the bottom block 4, and a card slot 13 is formed on both sides of the slide groove 12. The mounting plate 1 includes a main body 14 and a fixing portion 15 formed on both sides of the main body 14. The main body 14 can be slidably mounted on the slide groove 12 along the card slot 13. The fixing portion 15 extends out of both sides of the bottom block 4. The limiting component at least includes a bracket 16. The upper parts of both sides of the bracket 16 are attached to both sides of the bottom block 4.

In addition, the exposed contact part of the auxiliary moving spring piece is also in the protective groove of the auxiliary moving spring seat, which plays a better protective role.

[0043] Furthermore, the bottom of the protection groove 8 is provided with a notch 17 to match the deformation of the contact portion of the auxiliary movable spring 3.

In this technical solution, the arrangement of the pressing block not only improves the structural strength of the bottom block, but also enables further pressing fit after the bottom block and the mounting block are clamped.

[0047] Further, the outer sides of the upper and lower inner walls of the clamping groove 13 are constructed as a first guiding inclined surface 23, and both sides of the lower end surface of the pressing block 22 are constructed as a second guiding inclined surface 24.

[0049] Further, a raised section 25 is formed on the contact portion. In this technical solution, the raised section can improve the structural strength of the auxiliary moving reed, and make the deformation of the contact portion start from the raised section, reducing the pressure on the connecting portion, and making the assembly of the connecting portion and the auxiliary moving spring seat tend to be stable during the deformation process of the auxiliary moving reed.

[0050] In this specific embodiment, aiming at the risks of inconvenient assembly and easy detachment existing in the fixing method of the auxiliary moving reed in the existing contactor, the above solution fixes the middle part of the auxiliary moving reed on the auxiliary moving reed seat after large-area insertion. The assembly of the auxiliary moving reed is convenient, and the assembly area between the auxiliary moving reed and the auxiliary moving reed seat is large.

The auxiliary moving reed assembly composed of the auxiliary moving reed and the auxiliary moving reed seat is slidably clamped with the mounting plate, which is convenient for assembly and plays a role in limiting the up and down positions of the auxiliary moving reed assembly. The fixing parts on both sides of the mounting plate are press-fitted and riveted with the bracket of the limiting assembly, and the structure is stable and reliable, making it extremely difficult for the auxiliary moving reed assembly to disengage from the left and right.
