Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a novel plastic base. Background Technology
[0002] Currently, transformers are constructed by drilling holes at the edges of their bases and then inserting the leads into these holes. However, due to the open-hole design, the leads cannot be secured at the edges of the base, nor can they be placed in the center, causing them to come out of the holes and affecting the assembly efficiency of the transformer. Therefore, there is an urgent need for a new type of plastic base to solve these problems. Utility Model Content
[0003] The purpose of this utility model is to provide a new type of plastic base to solve the technical problems of existing new plastic bases, such as the inability to fix the leads, which leads to the leads coming out and affecting the efficiency of transformer assembly.
[0004] This utility model discloses a novel plastic base, comprising a base plate and a side plate. The base plate has multiple lead wire slots on its edge, each lead wire slot including a central lead wire inlet and two side lead wire retaining holes. The lead wire inlet and the lead wire retaining holes are connected. The side plate has multiple contact seats for coil contacts to pass through.
[0005] Preferably, the side plate is perpendicular to the bottom plate and is L-shaped.
[0006] Preferably, the lead wire slot is an umbrella-shaped structure, the lead wire inlet is square, the lead wire locking hole is arc-shaped, and the lead wire locking holes on both sides of the lead wire inlet are mirrored and arranged in a figure-eight shape.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0008] This new type of plastic base includes a vertically arranged base plate and side plates. The edge of the base plate is provided with multiple lead wire slots, which are mainly used for lead wires to pass through and be fixed. The lead wire slots include lead wire inlets and lead wire retaining holes. The lead wires are passed through the lead wire inlets, and the lead wires in the lead wire retaining holes are retained and blocked by the base plates on both sides of the base edge to ensure that the lead wires will not slip out, thereby improving the stability of the transformer pins.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0015] like Figs. 1-3 As shown, this utility model discloses a novel plastic base on which a coil and a magnetic core are mounted. The base includes a base plate 1 and a side plate 2. The base plate 1 has multiple lead wire slots 11 along its edge. Each lead wire slot 11 includes a central lead wire inlet 111 and two lead wire retaining holes 112 on either side. The lead wire inlet 111 communicates with the lead wire retaining holes 112. The side plate 2 has multiple contact seats 21 for the coil contacts 3 to pass through. The side plate 2 is perpendicular to the base plate 1 and is L-shaped. The lead wire slots 11 have an umbrella-like structure, the lead wire inlet 111 is square, the lead wire retaining holes 112 are arc-shaped, and the lead wire retaining holes 112 on either side of the lead wire inlet 111 are mirror-shaped, forming a figure-eight shape.
[0016] This utility model discloses a novel plastic base, which mainly serves to fix the lead wires of the transformer's internal windings (i.e., coils) and support the transformer body. The system includes a vertically arranged base plate 1 and side plates 2. The base plate 1 has multiple lead wire slots 11 on its edge, the number of which corresponds to the number of coils inside the transformer. These slots are mainly used for the lead wires to pass through and be fixed. Each lead wire slot 11 includes a lead wire inlet hole 111 and a lead wire retaining hole 112. The lead wire inlet hole 111 allows the lead wire to pass through, while the lead wire in the retaining hole 112 is held and blocked by the base plates on both sides of the base edge, ensuring that the lead wire does not slip out. During assembly, the lead wire passes through the lead wire inlet hole 111 and is held in place by the lead wire retaining holes 112 on both sides, improving the assembly efficiency of the base and the coil 4. By setting the lead wire slots 11 to an umbrella-shaped structure, the lead wire inlet hole 111 and the lead wire retaining hole 112 are not on the same horizontal line. When the lead wire enters from the lead wire inlet hole 111, it is then bent into the lead wire retaining hole 112, so that the lead wire can be held in place by the lead wire retaining hole 112 and not fall off. The novel plastic base of this application can also ensure the coil pin size, while improving assembly efficiency and enhancing the robustness of the transformer pins.
[0017] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
