Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, and more particularly to a multi-section power plug structure. Background Art

[0002] As the trend of intelligent and networked electrical equipment becomes increasingly obvious, the requirements for power plugs are no longer limited to simple power connections. Many modern electrical equipment need to transmit signals with the control system. Traditional plugs with only positive and negative poles can no longer meet the needs of current intelligent devices.

[0003] For signal transmission, flat metal point-contact connectors are currently the primary method. These connectors feature multiple inner and outer metal rings. When connected to a socket, the rings contact the metal points on the socket, simultaneously achieving multiple functions such as power connection and signal transmission. However, if the socket's surface is not machined with sufficient precision, flashing may occur on the surface, easily damaging the metal plate and causing poor contact, thus affecting signal transmission quality. Therefore, a new power connector structure is needed to address these issues. Utility Model Content

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] A multi-stage power plug structure, such as Figures 1 to 4 As shown, it includes a socket 1 and a plug 3. The socket 1 is provided with a plug-in slot 2, and the plug 3 is provided with a plug-in column 4. The plug 3 and the socket 1 are plugged into the plug-in slot 2 through the plug-in column 4. A number of metal ring sheets 5 are provided in the plug-in slot 2. The metal ring sheets 5 are arranged in a circle around the inner wall of the plug-in slot 2, and the metal ring sheets 5 are arranged along the depth direction of the plug-in slot 2. A number of metal spring sheets 6 protrude from the side wall of the plug-in column 4. The metal spring sheets 6 are arranged along the length direction of the plug-in column 4. The number of metal spring sheets 6 is the same as that of the metal ring sheets 5. When the plug-in column 4 is inserted into the plug-in slot 2, the metal spring sheets 6 respectively abut against the metal ring sheets 5 one by one.

[0026] The socket 1 is provided with a first pin 7 connected to the metal ring 5, and the plug 3 is provided with a second pin 8 connected to the metal spring 6. The socket 1 is connected to the first device through the first pin 7, and the plug 3 is connected to the second device through the second pin 8. Multiple functions are realized by contacting the metal ring 5 with multiple metal springs 6. In this embodiment, there are three metal springs 6 and three metal rings 5 ​​respectively, including positive and negative poles of the power supply and signal transmission. In other embodiments, the number can be increased according to functional requirements.

[0027] The plug-in column 4 includes several sections of cylindrical and coaxially arranged sub-columns 401. The closer the sub-columns 401 are to the bottom of the plug-in slot 2, the smaller the diameter is. The inner wall of the plug-in slot 2 is provided with several steps 9 that cooperate with the sub-columns 401. When the plug-in column 4 is inserted into the plug-in slot 2, the connection points of the sub-columns 401 are respectively fitted with the tops of the steps 9.

[0028] In this embodiment, the plug-in column 4 specifically includes three sub-columns 401, and the three metal springs 6 are respectively arranged on the peripheral side walls of the sub-columns 401. The metal ring pieces 5 are respectively arranged on the inner wall of the plug-in slot 2 and the inner wall of the step 9. The closer the metal ring piece 5 is to the bottom of the plug-in slot 2, the smaller the diameter of the metal ring piece 5 is. The metal ring piece 5 near the opening of the plug-in slot 2 is arranged on the inner wall of the plug-in slot 2, and the two metal ring pieces 5 below are arranged on the inner wall of the step 9.

[0029] The bottom of the metal ring piece 5 fits with the top of the step 9, and the bottom of the lowest metal ring piece 5 fits with the bottom of the plug-in slot 2. A connecting piece 10 protrudes from the bottom of the metal ring piece 5. The connecting piece 10 passes through the outside of the socket 1 toward the bottom of the plug-in slot 2 to form a first pin 7. Specifically, through holes are respectively opened at the top of the step 9 and the bottom of the slot, and the through holes pass through the socket 1 downward. The connecting pieces 10 pass through the socket 1 through the through holes respectively, and the three connecting pieces 10 form three first pins 7.

[0030] like Figure 1 and Figure 5 As shown, the top of the metal spring 6 extends upward and penetrates to the outside of the plug 3 to form a second pin 8. Specifically, through holes are respectively opened in the sub-column 401, and the through holes penetrate the plug 3 upward. The tops of the metal springs 6 pass through the plug 3 through the through holes respectively. Three metal springs 6 form three second pins 8. The bottom of the through hole penetrates the peripheral side wall of the sub-column 401, so that the bottom of the metal spring 6 passes through the peripheral side wall of the sub-column 401 and contacts the metal ring sheet 5. When the plug-in column 4 is inserted into the plug-in slot 2, the metal spring 6 is compressed into the through hole. The elastic force of the metal spring 6 makes the connection between the plug-in column 4 and the plug-in slot 2 more stable.

[0031] A limit plate 11 is provided on the plug 3 and at the top of the plug-in column 4. The limit plate 11 is circular and coaxially arranged with the plug-in column 4. The diameter of the limit plate 11 is larger than the diameter of the opening of the plug-in slot 2. When the plug-in column 4 is inserted until the limit plate 11 is in contact with the opening of the plug-in slot 2, the plug-in column 4 cannot continue to extend. At this time, there is still a distance between the bottom end of the plug-in column 4 and the bottom of the plug-in slot 2.

[0032] The included angle between adjacent metal domes 6 is at least 90°. In this embodiment, the included angle between the top metal dome 6 and the middle metal dome 6 is 90°, while the included angle between the middle metal dome 6 and the bottom metal dome 6 is 180°.

[0033] A contact portion 12 protrudes from the surface of the metal spring 6, and the edge of the contact portion 12 is an arc-shaped transition. The contact portion 12 and the metal spring 6 are integrally formed. The metal spring 6 abuts against the metal ring 5 through the contact portion 12. Since the edge of the contact portion 12 is an arc-shaped transition, the plug 3 is not easy to get stuck when rotating, and will not damage the metal ring 5.

[0034] The working process of this utility model is as follows:.

[0035] The user inserts the plug post 4 into the plug slot 2 by using external force, and the connection is achieved through the friction between the side walls of the plug post 4 and the metal spring 6 and the metal ring 5. The metal spring 6 contacts the metal ring 5 respectively to achieve power supply and signal transmission. Since the metal ring 5 is ring-shaped, the plug 3 can be inserted at any angle and can be rotated at will. When it needs to be unplugged, just use external force to pull the plug post 4 outward.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
