Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric reactor, specifically relates to a front-stretching type combined electric reactor terminal structure. BACKGROUND

[0002] In the existing household electric appliance electric reactor field, the product winding wire and terminal welding generally adopt electric soldering iron welding or immersion tin pool welding. Immersion tin pool welding requires that the electric reactor terminal welding position is located at the front end of the product, and is suitable for plug-in sheet claw type electric reactors. However, with the diversification of customer end connecting piece demand, the electric reactor more adopts the combined terminal of terminal table plus terminal sheet. Such as the terminal table electric reactor positioning structure disclosed by Chinese patent CN220290608U, including insulating base and conductive parts, but there are still the following problems: the traditional combined terminal is fixed by the mode of inserting the terminal sheet, bending the fixed sheet and pressure connecting the wire, and soldering iron welding, which is limited by the plug-in direction and processing technology, and the terminal welding position is often located at the lower edge of the terminal table, and immersion tin pool welding cannot be used. At the same time, the terminal claw space is limited, and the wire grabbing claw form is single, which leads to low efficiency. SUMMARY

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a front-stretching type combined electric reactor terminal structure.

[0004] The technical scheme adopted by the utility model is as follows:

[0007] The terminal sheet is arranged in a Z shape and is sequentially divided into an upper edge part, an import part and a claw part from top to bottom. The cross section of the upper edge part matches the sunken groove and is limited in the sunken groove. The import part enters and clamps in the clamping groove through the import gap, and the two sides of the import part extend the limiting pieces abutting against the bottom edge of the sunken groove.

[0008] The technical scheme improves the structure of the terminal table and the terminal sheet, makes the welding position of the electric reactor protrude forward, and through batch immersion in a tin pool for welding, greatly reduces the labor cost of manual welding. Specifically, the sinking fitting groove provides additional support area, enhances the structural strength of the terminal table; the sinking fitting groove can also effectively prevent the lateral movement of the terminal sheet during insertion, ensuring the stability of the structure; the front insertion type assembly structure of the terminal table allows the terminal sheet to be inserted into the terminal table at a certain direction and depth, ensuring that the terminal sheet can be firmly fixed on the terminal table, reducing the risk of loosening caused by vibration or temperature change; the close cooperation of the limiting sheet and the clamping groove not only prevents the terminal sheet from falling off, but also provides additional fixing force; since the terminal sheet is front insertion type, complex welding operations on the electric reactor are not required, thereby reducing labor costs; at the same time, since the welding position protrudes forward, batch welding is also easier to achieve, improving production efficiency; the process of bending the terminal limiting sheet on both sides after assembling the traditional terminal sheet is reduced to only once, which not only simplifies the manufacturing process, but also reduces the manufacturing cost.

[0009] In addition, according to the front-protruding combined electric reactor terminal structure provided in the utility model, the following additional technical features are also provided.

[0014] According to an embodiment of the utility model, the limiting sheet is initially inserted into the guide opening in a horizontal state, and after the limiting sheet is inserted into the guide opening, it is bent by 90°, so that the top edge of the limiting sheet is tightly attached to the bottom edge of the sunken groove, thereby ensuring that the terminal sheet is firmly fixed on the terminal table.

[0015] The technical scheme of the utility model bends the limiting sheet by 90° after it is inserted into the guide opening, thereby ensuring that the terminal sheet is firmly fixed on the terminal table and improving the stability of the structure.
