Description

Technical Field

[0001] This utility model belongs to the field of contact plate technology, and in particular relates to a high-low misaligned contact plate for switch sockets. Background Technology

[0002] In low-voltage electrical components such as switches and sockets, contact pieces and their contacts are the core components for realizing circuit switching and current conduction: as a connection carrier, the contact piece is responsible for stable connection with wires and sockets to build a current path; the contact piece accurately completes circuit switching through contact and separation actions, and the two work together to ensure the basic operation of electrical appliances.

[0003] In existing technologies, contact pieces are mostly designed to be relatively short. While this approach can adapt to miniaturized equipment and control production costs, it has significant room for optimization. Limited by the contact piece length, it's difficult to provide sufficient installation layout space for the contacts corresponding to multiple sets of switches and different types of sockets (such as two-hole and three-hole). This limitation compresses the contact spacing, making it difficult to achieve a compact and independent arrangement of switches and sockets. It may also lead to mutual interference between contacts during switch operation, affecting the accuracy of independent control of multiple sets of switches. Simultaneously, it results in excessively narrow socket spacing, hindering the simultaneous connection of multiple devices and reducing ease of use. Utility Model Content

[0004] The purpose of this utility model is to provide a high-low misaligned contact piece for switches and sockets, which aims to solve the technical problems in the prior art where the contact piece is designed to be too short, resulting in insufficient contact spacing and limited layout, which in turn causes the contacts to easily interfere with each other when the switch button is operated, and the socket hole spacing is too narrow, affecting the simultaneous use of multiple devices.

[0005] To achieve the above objectives, this utility model provides a staggered contact piece for a switch and socket, comprising a contact element, a contact mounting element, and a connector; the contact mounting elements are a first contact mounting element and a second contact mounting element; the first contact mounting element and the second contact mounting element are respectively provided with contacts; the first contact mounting element and the second contact mounting element are respectively disposed at both ends of the connector, and the contact element is disposed at the end of the first contact mounting element away from the connector; the first contact mounting element and the second contact mounting element are arranged in a staggered manner on a plane.

[0006] Furthermore, the contact element, contact mounting element, and connector are integrally molded structures.

[0007] Furthermore, the contact element includes a connecting plate and structural plates disposed on both sides of the connecting plate.

[0008] Furthermore, the connecting plate connects to the first contact mounting component; the structural plate is arranged in a "V" shape.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0022] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] In the field of low-voltage electrical appliances, the core function of switches and sockets relies on the synergistic effect of contact plates and contacts: as the current conduction carrier, the contact plate needs to stably connect the wires and the socket; the contacts realize the circuit opening and closing through mechanical contact and separation. The rationality of the structure of the two affects the conductivity stability and operational reliability of the product.

[0026] In the first embodiment of this utility model, as Figure 1 As shown, a staggered contact piece for a switch and socket includes a contact element 1, a contact mounting element, and a connector 3, all of which are integrally formed copper sheet structures. Formed through a single stamping process, it eliminates connection gaps and assembly deviations associated with spliced ​​or welded structures. During current conduction, compared to spliced ​​or welded structures, the integral copper sheet structure exhibits lower resistance, lower heat generation, and better elasticity, not only improving conductivity and safety but also preventing contact resistance fluctuations caused by loose assembly, thus reducing current transmission losses. In long-term mechanical operations (such as repeated pressing of switch buttons and insertion / removal of socket plugs), the integral structure effectively resists mechanical stress generated by insertion / removal forces and vibrations, reducing the risk of structural damage due to component connection failures and increasing service life.

[0027] Specifically, the contact mounting component includes a first contact mounting component 21; the contact 1 includes a connecting plate 11 and structural plates 12 disposed on both sides of the connecting plate 11; each structural plate 12 is arranged in a "V" shape on both sides of the connecting plate 11. The connecting plate 11 serves as a connecting bridge between the contact 1 and the first contact mounting component 21, ensuring a stable connection between the contact 1 and the first contact mounting component 21. Addressing the issue that the rectangular flat structure of the contact 1 results in a small contact area with the wires and sockets, this embodiment uses a "V"-shaped design on both sides of the connecting plate 11 to increase the contact area between the contact 1 and the plug, thereby improving conductivity stability.

[0028] Preferably, such as Figure 2 As shown, the first included angle A between the connecting plate 11 and the first contact mounting member 21 is 80°-100°, preferably 92°-94°. When the first included angle A between the contact member 1 and the first contact mounting member 21 is 92°-94°, it can provide stable support. When the plug is inserted, the plug is in full contact with the structural plate 12, and the contact member 1 will smoothly transmit the external insertion force to the contact member 1, the contact mounting member, and the connecting member 3, avoiding local stress concentration and preventing deformation of the contact piece.

[0029] Specifically, such as Figure 1-2As shown, the contact mounting component also includes a second contact mounting component 22, and contacts 4 are respectively provided on the first contact mounting component 21 and the second contact mounting component 22. The first contact mounting component 21 and the second contact mounting component 22 are respectively disposed at both ends of the connector 3, and the contact element 1 is disposed at the end of the first contact mounting component 21 away from the connector 3. Specifically, one end of the connector 3 is bent along the first contact mounting component 21, and the second included angle B between the connector 3 and the first contact mounting component 21 is 100°-150°, and the third included angle C between the connector 3 and the first contact mounting component 21 is 90°-110°; the second contact mounting component 22 is bent along the other end of the connector 3, and the fourth included angle D between the second contact mounting component 22 and the connector 3 is 90°-110°.

[0030] Specifically, such as Figure 1-3 As shown, the first contact mounting component 21 and the second contact mounting component 22 are arranged at different heights in the plane. The first contact mounting component 21 and the second contact mounting component 22 have a height difference in the horizontal plane and are arranged at different heights in the vertical plane via the connector 3. The core function of the connector 3 is to realize the spatial extension and staggered arrangement of the first contact mounting component 21 and the second contact mounting component 22, providing a reasonable layout for their contacts 4. The spatial extension is reflected in the height difference between the first contact mounting component 21 and the second contact mounting component 22 in the horizontal plane, providing independent space for their contacts 4 (e.g., ...). Figure 2 (As shown); misaligned arrangement refers to the fact that the contacts 4 of the first contact mounting component 21 and the second contact mounting component 22 do not overlap in the vertical plane (e.g. Figure 1 , 3 As shown), the distance between the contact 4 of the first contact mounting 21 and the contact 4 of the second contact mounting 22 is increased, making it less likely for the two contacts 4 to interfere with each other.

[0031] When in use, pressing the switch button causes the first contact mounting member 21 to deform downwards under the force of the external switch press. This causes the contact 4 of the first contact mounting member 21 to contact the conductive mechanism at one end. The downward deformation of the first contact mounting member 21 also causes the second contact mounting member 22 to displace downwards, causing its contact 4 to contact the conductive mechanism at the other end, thus conducting current. When the switch button is closed, the first contact mounting member 21 returns to its original deformation, and the contact 4 of the second contact mounting member 22 disconnects from the conductive mechanism at the other end, thus discontinuing current flow.

[0032] When the switch button is pressed or closed, the contacts 4 of the two switches can complete the contact and separation action within their respective spatial layers, avoiding mechanical interference caused by excessively narrow spacing in the plane. This also provides a structural basis for the compact arrangement of multiple sets of switches and different types of sockets. The connector 3 optimizes the layout of the two sets of contacts 4 while maintaining the overall rigidity and stability of the contact pieces.

[0033] Specifically, contact 4 is circular with a thickness greater than 0.1 mm. Preferably, the contact material is a silver-nickel alloy, which has excellent and stable resistance to welding and arc erosion, and a long service life.

[0034] Specifically, such as Figure 3 As shown, the first contact mounting member 21 is L-shaped, including a first planar segment 211 and a second planar segment 212. From the perspective of spatial layout and compatibility with the contact 4 of the first contact mounting member 21, the two planar segments of the L-shaped structure perform different functions: one end of the first planar segment 211 is connected to the contact member 1, forming a spatial layout suitable for the switch socket, and the other end of the first planar segment 211 near the second planar segment 212 has a constriction portion, which can disperse the stress generated by the contact 4 of the first contact mounting member 21 when it contacts and separates from the external wire, avoiding excessive stress concentration; the second planar segment 212 is connected to the second contact mounting member 22 through the connector 3, realizing the mechanical connection of the two contact mounting members; and serves as the mounting surface of the contact 4 of the first contact mounting member 21, used to fix the contact 4. The L-shaped structure can enhance the mechanical strength of the first contact mounting member 21, effectively resisting the reaction force generated by the contact 4 of the first contact mounting member 21 when it contacts and separates during the operation of the contact 4, and avoiding deformation of the contact piece.

[0035] Specifically, the contacts 4 of the first contact mounting member 21 are located on the upper surface of the first contact mounting member 21, and the contacts 4 of the second contact mounting member 22 are located on the lower surface of the second contact mounting member 22. The operating trajectories of the two sets of contacts 4 are independent and have no overlapping areas, reducing the risk of crowding and collision. Preferably, the surfaces of the contact member 1, the contact mounting member, and the connector 3 are provided with a metal wear-resistant layer. This reduces the mechanical wear of the contact member 1 and the connector 3, extends the overall lifespan of the contact piece, and is suitable for humid and dusty environments (such as bathrooms and kitchens), improving environmental adaptability.

[0036] In another embodiment of this utility model, the contacts 4 of the first contact mounting member 21 are disposed on the upper surface of the first contact mounting member 21, and the contacts 4 of the second contact mounting member 22 are disposed on the upper surface of the second contact mounting member 22. This embodiment is suitable for scenarios where multiple contacts 4 need to be switched on and off simultaneously. When the external mechanism moves downward, it can allow two sets of contacts 4 to contact the corresponding conductive mechanism at the same time.

[0037] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
