Description

Technical Field

[0001] This utility model relates to the field of contact technology, and in particular to a stepped composite silver contact. Background Technology

[0002] Stepped composite silver contacts are a key component in switching electrical appliances. Their structural design aims to improve the contact's positioning accuracy, conductivity, and stability. In practical applications, the contacts are typically fixed to the contact bridge by riveting. However, traditional riveting methods have certain limitations, such as the tendency for positional shifts to occur during installation, thus affecting the arc-extinguishing effect of the electrical appliance.

[0003] A typical stepped composite silver contact consists of stepped silver contacts, a connecting mechanism, etc. Therefore, when in use, the stepped silver contact effectively improves contact stability and resistance to arc erosion due to its multi-layer stepped design and excellent conductivity. The connecting mechanism connects the contacts to external circuit components through reliable electrical connection, preventing current leakage and short circuit.

[0004] However, some existing devices cannot provide good guiding and positioning functions during installation and use. Traditional contact devices often lack precise positioning structures, causing the contacts to easily shift position when connected to the contact bridge. This positional shift not only affects the contact stability between the contact and the contact bridge but also leads to poor contact problems. To address these issues, a stepped composite silver contact is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stepped composite silver contact, which aims to improve the problem that some devices in the prior art cannot provide good guiding and positioning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stepped composite silver contact includes a contact body, a protective mechanism is provided on the outside of the contact body, a plurality of contact pins are fixedly connected to the bottom of the contact body, and a positioning mechanism is provided at the bottom of the contact body;

Multiple connecting columns are fixedly connected to the bottom of the two support plates, and curved rings are fixedly connected to the bottom of the multiple connecting columns. A conductive component is fixedly connected to the outside of the contact body.

[0010] The conductive component includes a conductive layer, the outside of which is fixedly connected to the outside of the contact body, and a protective layer is fixedly connected to the outside of the conductive layer, i.e., the side away from the contact body.

[0011] As a further description of the above technical solution:

[0012] The protective mechanism includes two support rods, which are externally fixedly connected to the outer sides of the contact body, and the two support rods are provided with slots inside;

[0013] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The external of the lever is fixedly connected to a protective box, and the external of the contact body is located inside the protective box;

[0017] As a further description of the above technical solution:

[0018] The curved ring is designed in an arc shape, and in a vertical state, the length of the contact pin is equal to the length of the connecting post and the curved ring.

[0019] As a further description of the above technical solution:

[0020] The slot is designed in a triangular shape, and the outside of the lever can fit into the inside of the slot.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the alignment accuracy of the contact point is significantly improved by the initial positioning of the curved ring and the cooperation of the contact pins. The support plate and connecting column provide stable support for the contact body, ensuring that the contact body will not shake or shift during operation.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 5 to 7 An embodiment of this utility model is provided: a stepped composite silver contact, including a contact body 1, a protective mechanism 2 is provided on the outside of the contact body 1, a plurality of contact pins 3 are fixedly connected to the bottom of the contact body 1, and a positioning mechanism 4 is provided at the bottom of the contact body 1.

[0035] The positioning mechanism 4 includes two support plates 41, designed to provide good support. The two support plates 41 are externally fixedly connected to the bottom sides of the contact body 1, and the external surfaces of multiple contact pins 3 are located on adjacent sides of the two support plates 41. Multiple connecting posts 42 are fixedly connected to the bottom of the two support plates 41, designed to provide good connection. Curved rings 43 are fixedly connected to the bottom of the multiple connecting posts 42, designed to provide good sliding ability, allowing the contact body 1 to slide via the support plates 41 connected to the connecting posts 42. With proper alignment, a conductive component is fixedly connected to the outside of the contact body 1. The conductive component includes a conductive layer 45, the main function of which is to improve the conductivity of the contact body. The conductive layer 45 is fixedly connected to the outside of the contact body 1. A protective layer 44 is fixedly connected to the outside of the conductive layer 45, i.e., the side away from the contact body 1, to protect the conductive layer 45 and prevent it from being affected by external environmental factors. The curved ring 43 is designed in an arc shape, and in the vertical state, the length of the contact pin 3 is connected to the bottom post 42 and the length of the curved ring 43.

[0036] Reference Figures 1 to 4 The protective mechanism 2 includes two support rods 23, which are designed to provide good support. The two support rods 23 are fixedly connected to the outside of the contact body 1 on both sides. The two support rods 23 have slots 24 inside, which are designed to provide good placement space and alignment. The slots 24 are slidably connected to the inside of the slots 24, which are designed to provide good alignment, so as to prevent the inside of the slots 24 from being blocked. The outside of the slots 22 is located on the top of the support plate 41. The outside of the slots 22 is fixedly connected to the protective box 21, which is designed to provide good protection and reduce contact with air. The outside of the contact body 1 is located inside the protective box 21. The slots 24 are triangular in shape, and the outside of the slots 22 can fit into the inside of the slots 24.

[0037] Working principle: First, the contact pin 3 connects to the contact bridge, and the current enters the contact body 1 through the contact pin 3. The contact body 1 acts as the current transmitter, and the conductive layer 45 further enhances its conductivity, ensuring efficient and stable current transmission. The protective layer 44 protects the conductive layer 45 from external environmental factors, thus ensuring the stability of the conductive layer 45's performance and extending its service life. At the bottom of the contact body 1, the positioning mechanism 4 plays a crucial role. Two support plates 41 provide stable support for the contact body 1, ensuring its positional stability and accuracy during operation. When the contact position needs adjustment, the support plates 41 connected by the connecting column 42 drive the contact body 1 to slide. The curved ring 43, with its arc-shaped design, achieves excellent sliding capability, allowing the contact body 1 to be smoothly aligned. It first achieves good positioning through the curved ring 43, and then through the contact pin 3, thus ensuring the contact stability and reliability between the contact and the contact bridge.

[0038] During use, the protective mechanism 2 plays a crucial role in protecting itself from external environmental influences, preventing damage from oxidation, corrosion, and other environmental factors. The cooperation between the locking rod 22 and the locking slot 24 is key to achieving stable fixation and precise alignment of the protective mechanism 2. The triangular design inside the locking slot 24 provides a stable placement space and excellent alignment capability for the locking rod 22, allowing it to accurately embed and tightly fit against the inner wall of the slot 24. This tight fit not only ensures a secure connection between the protective box 21 and the support rod 23 but also allows the protective box 21 to be precisely positioned on the support rod 23, thus guaranteeing the stability of the entire protective mechanism 2 during operation. The support rod 23 provides necessary support for the protective mechanism 2, enabling it to be stably fixed to both sides of the contact body 1, thus providing all-around protection for the contact body 1. Through this design, the protective mechanism 2 effectively protects the contact body 1 during operation, ensuring its good performance and stability under various environmental conditions.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
