Description

Technical Field

[0001] This utility model relates to the field of socket technology, and more particularly to multi-point contact sockets. Background Technology

[0002] A socket is an interface in an electrical system used to connect a power source to electrical equipment. It allows current to flow from the power source to the connected device. Sockets are usually installed on walls, furniture, or other fixed locations and are an indispensable part of daily life in homes, offices, industrial sites, and other places.

[0003] In existing sockets, to maintain the stability of the connection between the plug and the socket's connection hole, elastic metal clips are used to hold the plug's metal prongs in place after the plug is inserted. This provides a certain degree of fixation, and the plug is then connected to the terminal block to conduct electricity. However, with prolonged use, frequent plugging and unplugging causes the metal clips to repeatedly open and close. This gradually fatigues the internal metal structure, much like a spring whose elasticity decreases after repeated stretching and compression. Similarly, frequent plugging and unplugging over a long period will cause the metal clips to slowly lose their elasticity and fail to hold the plug securely. This may result in appliances being unable to obtain the required current stably, leading to unstable operation and performance degradation.

[0004] Therefore, it is necessary to provide new multi-point contact sockets to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-point contact socket.

[0006] The multi-point contact socket provided by this utility model includes a bottom shell, and a top shell is detachably connected to the top of the bottom shell by bolts. The top shell has several connection holes. Several support plates are fixedly connected between the bottom shell and the top shell. A circuit board is fixedly connected to one end of the support plates away from the top shell. The circuit board is fixedly connected to the inner wall of the bottom shell. Metal springs are provided on the support plates. One end of the metal spring is connected to the support plate, and the other end of the metal spring is provided with a contact point.

[0007] Preferably, the metal springs are arranged opposite each other, and the contacts on the two oppositely arranged metal springs are adjacent to each other. The contacts are disposed on the surface of the metal springs and are spherical.

[0008] Preferably, a connecting post is fixedly connected to the inner wall of the through hole opened on one side of the bottom shell and the top shell, and a connecting wire harness is connected to the end of the connecting post away from the bottom shell and the top shell.

[0009] Preferably, an LED bead is fixedly connected to the top of the circuit board, and the end of the LED bead away from the circuit board is disposed on the inner wall of a through hole opened on the top of the top housing.

[0010] Preferably, a switch button is slidably connected to the inner wall of the through hole at the top of the top housing.

[0011] Preferably, the circuit board is provided with a protective device, which includes an input component, a current limiter, and a temperature sensor. The input component is connected to the circuit board, the current limiter is connected to the end of the input component away from the circuit board, and the end of the current limiter away from the input component is connected to a rectifier bridge. The end of the rectifier bridge away from the current limiter is connected to a temperature sensor, and the end of the temperature sensor away from the rectifier bridge is connected to a receiving device.

[0012] Preferably, the metal spring and the contact are integrally formed.

[0013] Compared with related technologies, the multi-point contact socket provided by this utility model has the following advantages:

[0014] This utility model provides a multi-point contact socket. When the socket is needed, the plug to be connected to the socket is first inserted into the connection hole on the top shell. When the plug is inserted, it is secured by metal springs and contacts on the springs, and current is transmitted through these contacts and springs. This device maintains good elasticity of the metal springs and contacts even with frequent plugging and unplugging, ensuring a secure grip on the plug and allowing the appliance to stably receive the required current, preventing instability and performance degradation. Furthermore, each metal spring and contact is independently designed; even if one loses its elasticity or malfunctions, it will not affect the others. The independently designed metal springs and contacts also allow for easy insertion and removal of the plug, preventing difficulties in plugging and unplugging or loss of grip even after long-term use. By incorporating a protective device into the socket's circuitry, the socket automatically stops working and cuts off power when the temperature reaches a set value. This design prevents damage to the socket or appliance, avoids fires, and ensures safe use. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 ,in, Figure 1 This is a schematic diagram of the structure of the multi-point contact socket shown in this utility model; Figure 2 This is a cross-sectional view of the multi-point contact socket shown in this utility model; Figure 3 This is a cross-sectional view of the multi-point contact socket shown in this utility model from another perspective; Figure 4 This is an exploded view of the multi-point contact socket shown in this utility model.

[0027] like Figures 1 to 9As shown, a top outer shell 2 is detachably connected to the top of the bottom outer shell 1 via bolts. The top outer shell 2 has several connection holes 3. Several support plates 4 are fixedly connected between the bottom outer shell 1 and the top outer shell 2. A circuit board 5 is fixedly connected to one end of each support plate 4 away from the top outer shell 2. The circuit board 5 is fixedly connected to the inner wall of the bottom outer shell 1. Metal springs 6 are provided on the support plates 4. One end of the metal spring 6 is connected to the support plate 4, and the other end of the metal spring 6 has a contact 7. When the plug is inserted into the connection hole 3, the plug is fixed by the metal spring 6 and the contact 7 on the metal spring 6, and current is transmitted through the contact 7 and the metal spring 6. This device can maintain good elasticity of the metal spring 6 and the contact 7 even with frequent plugging and unplugging over a long period, effectively clamping the plug and ensuring that the electrical appliance can stably obtain the required current, preventing problems such as unstable operation and performance degradation.

[0028] The metal springs 6 are arranged opposite each other, usually in pairs. The contacts 7 on the two opposite metal springs 6 are adjacent, but the metal springs 6 do not touch, ensuring that they do not interfere with each other during operation. The contacts 7 are located at one end of the metal spring 6, specifically on the surface of that end. The contacts 7 are spherical, specifically a semi-circular protrusion at the center. The metal springs 6 and contacts 7 are integrally formed. Each metal spring and contact is independently configured; even if one loses its elasticity or malfunctions, it will not affect the other metal springs and contacts. Furthermore, the independently configured metal springs and contacts allow for easy insertion and removal of the plug, and will not lead to difficulty in insertion or removal or failure to clamp the plug after long-term use.

[0029] Connecting posts 8 are fixedly connected to the inner walls of the through holes on one side of the bottom housing 1 and the top housing 2. A connecting wire harness 9 is connected to the end of the connecting post 8 away from the bottom housing 1 and the top housing 2. An LED bead 10 is fixedly connected to the top of the circuit board 5. The end of the LED bead 10 away from the circuit board 5 is located inside the inner wall of the through hole at the top of the top housing 2. A switch button 11 is slidably connected to the inner wall of the through hole at the top of the top housing 2. During use, the power supply status of the socket can be determined by observing the LED bead 10. The switch button 11 controls the working status of the socket, allowing for convenient operation without disconnecting the power supply at the other end.

[0030] It should be noted that when using the socket, the socket can carry a large current through the interaction between the metal spring 6 and the contacts 7 on the metal spring 6. When appliances with high current are used in the socket, the socket will not overheat or explode, and it can effectively dissipate the heat generated by the high current, preventing overheating damage to the socket or its components.

[0031] The circuit board 5 is equipped with a protective device, which includes an input component, a current limiter, and a temperature sensor. The input component is connected to the circuit board 5. The current limiter is connected to the end of the input component away from the circuit board 5, and the end of the current limiter away from the input component is connected to a rectifier bridge. The end of the rectifier bridge away from the current limiter is connected to a temperature sensor, and the end of the temperature sensor away from the rectifier bridge is connected to a receiving device. The input component, current limiter, temperature sensor, rectifier bridge, temperature sensor, and receiving device are all electrically connected.

[0032] By installing a protective device on the socket's circuitry, the socket will automatically stop working and cut off the power when the temperature reaches a set value. This design can prevent damage to the socket or electrical appliances, and also prevent fires, ensuring safe use.

[0033] When using the socket, first insert the plug that needs to be connected to the socket into the connection hole 3 opened on the top housing 2. When the plug is inserted into the connection hole 3, the plug will be fixed by the metal spring 6 and the contact 7 set on the metal spring 6, and the current will be transmitted through the contact 7 and the metal spring 6.

[0034] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
