Description

Technical Field

[0001] This utility model relates to the field of slip ring technology, specifically a slip ring including a support frame. Background Technology

[0002] Slip rings, also known as conductor rings, are used in electromechanical systems to allow continuous power or signal transmission between rotating and stationary components. They are widely used in various rotating equipment, such as electric motors, generators, and power tools. Through sliding contact with brushes, they transmit current or signals, allowing rotating components to rotate freely without tangling cables or wires. Slip rings must be designed to have good conductivity, electrical breakdown resistance, abrasion resistance, mechanical strength, and corrosion resistance to ensure stable and reliable current transmission and a long lifespan. Especially for slip rings in automotive alternators, reliability is paramount; otherwise, the entire vehicle's power supply system may fail, leading to serious safety issues. Generally, the metal inserts in slip rings that are exposed for non-functional purposes are encased in plastic with sufficient thickness to prevent electrical breakdown. Because automotive alternators are highly integrated, slip ring designs are becoming smaller, and the increasing number of electrical components in vehicles requires higher voltages. Therefore, ensuring the thickness of the plastic coating on the insert inside the slip ring is a necessary means to ensure the slip ring's resistance to electrical breakdown. At the same time, fixing the position of the insert inside the slip ring also helps to improve the quality of the slip ring.

[0003] Most slip rings on the market currently consist of two strip inserts (one long and one short), two copper rings, and plastic. Generally, the two copper rings are welded to the two copper strip inserts (one long and one short) and then placed into an injection mold. As customers demand higher integration levels from generators and design space becomes increasingly limited, slip rings are becoming smaller, and the plastic thickness around the inserts is decreasing. The longer strip inserts, due to their greater length, are at higher risk of deformation and displacement. Simultaneously, with the increasing number of electrical components in vehicles and the higher voltage requirements, especially in specialized vehicles such as engineering vehicles and outdoor recreational vehicles, the traditional design of directly injection molding the welded copper ring insert assembly has become increasingly unproductive in mass production. A significant proportion of slip ring products fail after injection molding because the strip inserts twist and deform within the plastic, failing to maintain a safe thickness with the plastic, leading to electrical breakdown during electrical testing. This not only wastes production costs but also poses potential risks to vehicles. Summary of the Invention

[0004] The purpose of this utility model is to provide a current collector ring including a support frame, which can prevent the deformation of long strip inserts during the injection molding process without changing the product appearance, ensure the plastic thickness outside the insert, thereby eliminating the risk of electrical breakdown of the product, realizing the mass production capability of automated production of product injection molding, electrical testing and appearance inspection, and improving product production efficiency and product yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A current collector ring including a support frame includes a copper ring, an elongated insert, and a short strip insert, wherein the copper ring and the elongated insert are welded together to form an elongated insert welding assembly;

[0007] The copper ring is welded to the short strip insert to form the short strip insert;

[0008] A support frame is provided between the long strip-shaped insert welding assembly and the short strip-shaped insert, and the three are press-fitted into an integral assembly. The integral assembly and the plastic form a current collector ring.

[0009] Furthermore, the support frame is equipped with a tongue and a buckle.

[0010] Furthermore, the tongue, buckle, and elongated insert are fixed together.

[0011] Furthermore, the support frame is provided with insert protrusions.

[0012] Furthermore, the long strip-shaped insert welding assembly and the short strip-shaped insert are formed into an integral assembly by pressing with interlocking ribs.

[0013] Furthermore, the support frame is made of plastic.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By adding a support frame inside the collector ring, the deformation of the long strip insert during the injection molding process is avoided without changing the appearance of the product, the plastic thickness outside the insert is guaranteed, and the risk of electrical breakdown of the product is eliminated.

[0016] (2) By adding a support frame inside the slip ring, the long strip insert, short strip insert, and copper ring are combined into a movable whole in the previous process. In the injection molding process, a robot can pick up the assembled whole, thereby automating the injection molding process. At the same time, the subsequent electrical testing and appearance inspection are also automatically completed on a single integrated device. This achieves automation of injection molding, electrical testing, and appearance inspection, improving product production efficiency and product quality, and reducing costs.

[0017] (3) The added plastic support frame and the slip ring plastic are made of the same material, and the slip ring plastic will completely wrap the plastic support frame. After injection molding, they will be firmly integrated into a whole and there will be no risk of peeling or falling off. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] A current collector ring including a support frame includes a copper ring 1, an elongated insert 2, and a short insert 4. The copper ring 1 and the elongated insert 2 are welded to form an elongated insert welding assembly 3.

[0025] The copper ring 1 is welded to the short strip insert 4 to form the short strip insert welding assembly 5. The support frame 6 is installed between the long strip insert welding assembly 3 and the short strip insert welding assembly 5, and the three are pressed together to form an integral assembly 7. The integral assembly 7 and the plastic 9 form a current collector ring 8.

[0026] To achieve fixation, the support frame 6 is provided with a tongue 11 and a buckle 12 to fix the tongue 11, buckle 12 and elongated insert 2.

[0027] The support frame 6 is provided with a socket protrusion 10, which allows the long strip insert welding assembly 3 and the short strip insert welding assembly 5 to be press-fitted into an integral assembly 7 through the socket protrusion 10.

[0028] Working principle:

[0029] The collector ring 8 is mainly composed of a copper ring 1, a long strip insert 2, a short strip insert 4, a support frame 6, and plastic 9. In order to solve the deformation and movement of the two long strip inserts during the injection molding process of the collector ring, a support frame 6 was added. The material of the support frame 6 is the same as that of the plastic 9.

[0030] The support frame 6 is provided with a tongue 11 and a buckle 12. The long strip insert 2 is fixed by the tongue 11 and the buckle 12 to ensure that the long strip insert 2 does not deform during the subsequent injection molding process, thereby ensuring the thickness of the plastic wrapping on the outside of the long strip insert 2.

[0031] The rotating mechanism in the generator cuts magnetic induction lines to generate electromotive force. The electromotive force is guided to copper ring 1 through carbon brushes. The two copper rings 1 can be regarded as positive and negative poles. They are connected to the long strip insert 2 and the short strip insert 4 of the copper ring respectively to guide the electrical energy to the rectifier bridge regulator, which converts the alternating current into direct current for use by the vehicle's electrical appliances.
