Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic and electrical technology, specifically to a power supply connection device and a power socket. Background Technology
[0002] To date, the common power supply method or device is various power junction boxes or power strips. The user holds the power plug and inserts it vertically into the corresponding hole in the power socket to supply power to the appliance. During this process, the plug's prongs open the narrow space formed by the conductive contacts of the power socket's power supply terminals (which we call terminals), thus making contact with electricity. Current terminals are typically made by stamping a single piece of conductive material (usually a copper alloy). Their cross-section is often U-shaped with a narrow opening. This structure is simple to manufacture and relatively inexpensive, but it has several drawbacks: 1. The elasticity of the spring comes from its own bending deformation. Since the conductive material itself lacks elasticity, its elasticity decreases with repeated use, leading to poor contact, plug arcing, and intermittent power supply. 2. The contact area between the terminal spring and the plug prongs is relatively small, making it difficult to effectively increase the power supply, sometimes manifesting as socket overheating. 3. To achieve a longer lifespan, the spring force of the terminal spring is usually preset to be relatively large, making it more difficult for users to plug and unplug the plug, and also resulting in greater wear on both the terminal spring and the plug prongs.

Detailed Implementation
[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0030] This embodiment relates to a power supply connection device, see reference Figures 1-4The system includes: a mounting base 100, a first conductive element 200, a second conductive element 300, a first elastic reset element 500, and a second elastic reset element 600. The mounting base 100 has an insertion hole 110 on one side; the first conductive element 200 is movably mounted within the mounting base 100; the second conductive element 300 is movably mounted within the mounting base 100; the first conductive element 200 and the second conductive element 300 are arranged opposite to each other; and an insertion space 400 communicating with the insertion hole 110 is provided between the first conductive element 200 and the second conductive element 300; one end of the first elastic reset element 500 abuts against the first conductive element 200, and the other end abuts against the inner wall of the mounting base 100; one end of the second elastic reset element 600 abuts against the second conductive element 300, and the other end abuts against the inner wall of the mounting base 100. Specifically, a first elastic reset member 500 and a second elastic reset member 600 are respectively provided between the first conductive member 200 and the inner wall of the mounting base 100, and between the second conductive member 300 and the inner wall of the mounting base 100. When the external conductive member pushes the first conductive member 200 and the second conductive member 300 apart through the insertion hole 110 (at this time, the first elastic reset member 500 and the second elastic reset member 600 are in a compressed state) and inserts into the placement space 400, the first conductive member 200 and the second conductive member 300 clamp the external conductive member under the reaction force of the elastic force of the first elastic reset member 500 and the second elastic reset member 600, so as to realize the circuit conduction. This power supply connection method has a large conductive power and makes the conductive members less prone to deformation and wear. Furthermore, during the insertion of the external conductive component into the insertion space 400, the first conductive component 200 and the second conductive component 300 are constantly pressed against the external conductive component by the reaction force of the elastic force of the first elastic reset component 500 and the second elastic reset component 600, respectively. This ensures the reliability and stability of the electrical connection between the first conductive component 200, the second conductive component 300, and the external conductive component, preventing poor contact. In addition, the first elastic reset component 500 and the second elastic reset component 600 can effectively buffer the impact force on the first conductive component 200 and the second conductive component 300 when the external conductive component is inserted, preventing damage to the first conductive component 200, the second conductive component 300, or the mounting base 100 due to hard collisions, further improving the durability and reliability of this power supply connection device.
[0031] In this embodiment, the external conductive component can be a metal contact such as the pins of a plug. The first elastic reset member 500 and the second elastic reset member 600 are configured as springs. In some embodiments, the first elastic reset member 500 and the second elastic reset member 600 can also be spring sheets.
[0032] Furthermore, one or more of the first elastic reset member 500 and the second elastic reset member 600 are provided. In this embodiment, three of each of the first elastic reset member 500 and the second elastic reset member 600 are provided, corresponding to the upper end, middle part and lower end of the first conductive member 200 and the second conductive member 300, respectively, to provide a stable and balanced force.
[0033] Furthermore, both the first conductive element 200 and the second conductive element 300 are made of metal sheets in order to increase the contact area with external conductive elements, reduce contact resistance, and improve conductivity.
[0034] In this embodiment, refer to Figures 1-4 The first conductive member 200 has first bent portions 710 on both sides, with their free ends bent toward the second conductive member 300; the second conductive member 300 has second bent portions 720 on both sides, with their free ends bent toward the first conductive member 200 and abutting against the first bent portions 710. Specifically, there are two first bent portions 710 and two bent portions 720. When an external conductive member is inserted between the first conductive member 200 and the second conductive member 300 without the insertion hole 110, the first bent portions 710 and the second bent portions 720 abut against each other to form an insertion space 400 between the first conductive member 200 and the second conductive member 300, so that the external conductive member can be inserted. It also facilitates the user to remove the external conductive member. In this embodiment, the cross-sections of the first bent portions 710 and the second bent portions 720 are arc-shaped.
[0035] In some embodiments, the first conductive member 200 has a first extension shaft 210 extending towards both sides of the first conductive member 200 at one end near the insertion hole 110; the mounting base 100 has a first groove 121 for inserting the first extension shaft 210. The first extension shaft 210 and the first groove 121 cooperate to allow the first conductive member 200 to be movably assembled in the mounting base 100, and also facilitates installation and disassembly. In addition, the second conductive member 300 has a second extension shaft 310 extending towards both sides of the second conductive member 300 at one end near the insertion hole 110; the mounting base 100 has a second groove 131 for inserting the second extension shaft 310. The arrangement of the first extension shaft 210, the second extension shaft 310, the first groove 121 and the second groove 131 is such that when an external conductive member is inserted, it can open up the first conductive member 200 and the second conductive member 300, and also serves to limit the positioning of the first conductive member 200 and the second conductive member 300.
[0036] Furthermore, the cross-section of the first extension shaft 210 is U-shaped to facilitate smoother and more fluid movement of the first conductive element 200. In some embodiments, the cross-section of the second extension shaft 310 is also U-shaped to facilitate smoother and more fluid movement of the second conductive element 300.
[0037] In some embodiments, refer to Figure 4 The mounting base 100 has a first mounting groove 122 for inserting one end of the first elastic reset member 500. The power supply connection device also includes a first limiting post 123, one end of which is disposed within the first mounting groove 122 and the other end extends towards the first conductive member 200. The first limiting post 123 is fitted onto one end of the first elastic reset member 500. Specifically, the first mounting groove 122 limits one end of the first elastic reset member 500 to prevent displacement, and the first limiting post 123 prevents radial displacement of the first elastic reset member 500. Additionally, the mounting base 100 also has a second mounting groove 132 for inserting one end of the second elastic reset member 600. The power supply connection device also includes a second limiting post 133, one end of which is disposed within the second mounting groove 132 and the other end extends towards the second conductive member 300. The second limiting post 133 is fitted onto one end of the second elastic reset member 600. The second limiting post 133 prevents radial displacement of the second elastic reset member 600.
[0038] In some embodiments, refer to Figure 4 The first conductive element 200 and the second conductive element 300 are respectively provided with a first guide arc surface 220 and a second guide arc surface 320 at the end near the insertion hole 110, so as to reduce the direct impact on the first conductive element 200 and the second conductive element 300 when the external conductive element is inserted, and also reduce the wear of the contact surface between the first conductive element 200, the second conductive element 300 and the external conductive element, and also reduce the resistance when the external conductive element is inserted.
[0039] In this embodiment, the mounting base 100 includes a first housing 120 and a second housing 130 detachably assembled with the first housing 120, facilitating the installation of components such as the first elastic reset member 500, the second elastic reset member 600, the first conductive member 200, and the second conductive member 300. Specifically, the first housing 120 has a first snap-fit groove 124 on one side and a first snap-fit post 125 extending toward the second housing 130 on the other side; the second housing 130 has a second snap-fit post 135 extending toward the first housing 120 and engaging with the first snap-fit groove 124 on one side, and a second snap-fit groove 134 engaging with the first snap-fit post 125 on the other side. The snap-fit engagement between the first housing 120 and the second housing 130 facilitates maintenance and quick assembly / disassembly.
[0040] This embodiment also relates to a power socket, see reference Figures 5-6The power socket includes: a base plate 810; multiple power supply connection devices as described above disposed on the base plate 810; and a cover 820 disposed on the base plate 810 and having multiple through holes 821 corresponding to the sockets 110. For example, when three power supply connection devices are disposed in a wiring groove on the base plate 810, the cover 820 is provided with three corresponding through holes 821, and the power socket is a three-hole socket. This power socket has the advantages of convenient plug-and-unplugging for users, reliable electrical connection, and durability.
