Description

Technical Field

[0001] This invention relates to the field of power operation and maintenance technology, and in particular to a quick direct connection type socket. Background Technology

[0002] In existing power distribution systems, the copper busbars inside the power supply box typically only have threaded holes for bolt connections to connect to external electrical equipment. In practice, a conductive wire (such as an electric cable or braided copper wire) is used, with one end bolted into the threaded hole of the copper busbar and the other end connected to the electrical equipment. This connection method has the following problems:

[0003] Installation and disassembly are inefficient: each time electrical equipment is connected or disconnected, tools are needed to tighten or loosen bolts, which is cumbersome and time-consuming, and cannot meet the needs of scenarios that require frequent switching or temporary power supply (such as test equipment, mobile loads or emergency power access).

[0004] Poor safety: When using tools to tighten or loosen bolts, there is a high risk of electric shock.

[0005] Currently, there is a lack of electrical connection solutions on the market that are compatible with the threaded hole structure of the power supply copper busbar and support quick plug-in / out. Therefore, there is an urgent need to design a quick-connect socket that, while retaining the original threaded holes of the power supply copper busbar, enables an efficient, reliable, and flexible connection between electrical equipment and the power supply copper busbar, thereby improving operational efficiency and reducing operational risks.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] One objective of this invention is to provide a quick-connect socket that enables efficient, reliable, and flexible connection between electrical equipment and the power supply copper busbar while retaining the original threaded holes of the power supply copper busbar, thereby improving operational efficiency and reducing operational risks.

[0008] To achieve the above objectives, the present invention provides a quick direct connection type socket, comprising:

[0009] A magnetic bolt, wherein the circumferential surface of the magnetic bolt is provided with an external thread for threaded connection with the threaded hole of the power supply copper busbar, and the end face of one end of the magnetic bolt is provided with a positioning slot.

[0010] A quick-connect socket, the quick-connect socket including a metal spring for electrical connection with a plug, and a socket power terminal electrically connected to the metal spring;

[0011] The socket power terminal includes an annular contact portion and an insulating positioning post that protrudes toward the magnetic bolt through the hollow portion of the annular contact portion.

[0012] After the insulating positioning post is inserted into the positioning slot, the annular contact part abuts against the end face of the magnetic bolt under magnetic attraction.

[0013] Optionally, the magnetic bolt includes:

[0014] The bolt body includes a threaded sleeve with external threads and a limiting ring located on the side of the threaded sleeve near the quick-connect socket; wherein the diameter of the limiting ring is larger than the diameter of the threaded sleeve to restrict the limiting ring from passing through the threaded hole.

[0015] A rubber-coated magnetic connector is fixed to one end of the threaded sleeve away from the limiting ring and is used for magnetic connection with the quick-connect socket.

[0016] Optionally, the positioning slot extends from the limiting ring toward the threaded sleeve, and the bottom of the positioning slot is provided with an internal hexagonal groove.

[0017] Optionally, the coated magnetic attractor includes a first magnet and a first insulating coating covering the first magnet;

[0018] The insulating positioning post is provided with a second magnet for magnetically connecting with the first magnet.

[0019] Optionally, the quick-connect socket further includes:

[0020] The socket housing encloses an internal space. The side of the socket housing away from the magnetic bolt is provided with several panel holes for inserting the plug. The side of the socket housing near the magnetic bolt is provided with a terminal mounting window for accommodating the power supply terminals of the socket.

[0021] The metal spring is fixed in the internal space of the shell, and each panel socket is equipped with two metal springs arranged opposite to each other.

[0022] Optionally, the socket power terminal includes a second insulating coating that connects the socket housing and the annular contact portion;

[0023] The second insulating coating includes the insulating positioning post located inside the annular contact portion, the outer coating ring located outside the annular contact portion, and the annular connecting piece connecting the insulating positioning post and the outer coating ring.

[0024] Optionally, the annular connecting piece is provided with a plurality of through-holes, and the annular electrical contact part is provided with electrical contact posts passing through the through-holes.

[0025] Optionally, the terminal block is electrically connected to the corresponding metal spring via a wire.

[0026] Optionally, the number of power terminals of the socket is three, which are arranged in order as ground wire power terminal, neutral wire power terminal and live wire power terminal, and the three power terminals of the socket are arranged in order from top to bottom.

[0027] Optionally, the socket housing is made of rigid plastic, the second insulating coating is made of silicone or rubber, and the annular contact part is made of metal.

[0028] The socket housing, the second insulating coating, and the annular contact part are connected by in-mold two-color injection molding, and the circumferential surface of the second insulating coating is provided with an anti-detachment protrusion that extends into the socket housing.

[0029] The beneficial effects of this invention are as follows: It provides a quick-connect socket, which effectively solves the efficiency and safety problems of traditional bolt connection methods through the coordinated design of magnetic screws and quick-connect sockets.

[0030] First, the magnetic bolt is pre-screwed into the threaded hole of the power supply copper busbar, maintaining the original structural compatibility. The quick-connect socket uses an insulated positioning post that precisely aligns with the positioning slot of the magnetic bolt. Combined with the magnetic attraction, the annular contact part tightly fits against the bolt end face, forming a stable conductive path. This design transforms the traditional tool-operated bolt connection into a plug-and-play operation that can be completed by hand, significantly improving operational efficiency and flexibility, and is particularly suitable for scenarios requiring frequent connection switching.

[0031] Secondly, in terms of safety, the operator does not need to directly contact the live copper busbar; the plugging and unplugging process is completed through an insulator, reducing the risk of electric shock. The quick-connect socket provided by this invention, while retaining the original structure of the power supply box, achieves faster and safer power supply for electrical equipment, providing a more convenient and reliable solution for power operation and maintenance.

[0032] Therefore, the quick-connect socket provided by the present invention can achieve an efficient, reliable and flexible connection between power equipment and power supply copper busbar while retaining the original threaded holes of the power supply copper busbar, so as to improve work efficiency and reduce work risks.

[0048] See Figure 1 and Figure 2 The present invention provides a quick direct connection type socket, comprising:

[0049] A magnetic bolt 1, wherein the circumferential surface of the magnetic bolt 1 is provided with an external thread for threaded connection with the threaded hole of the power supply copper busbar, and the end face of one end of the magnetic bolt 1 is provided with a positioning slot 103.

[0050] The quick-connect socket 2 includes a metal spring 201 for electrical connection with a plug, and a socket power terminal electrically connected to the metal spring 201.

[0051] The socket power terminal includes an annular power receiving part 2021 and an insulating positioning post 2022a protruding toward the magnetic bolt 1 through the hollow position of the annular power receiving part 2021.

[0052] After the insulating positioning post 2022a is inserted into the positioning slot 103, the annular contact part 2021 abuts against the end face of the magnetic bolt 1 under magnetic attraction.

[0053] The quick-connect socket provided in this embodiment is used as follows:

[0054] I. Off-peak equipment upgrade phase

[0055] Before supplying power to electrical equipment, the existing power supply copper busbars should be upgraded during off-peak hours. The specific upgrade steps are as follows: Install the magnetic bolt 1 and quick-connect socket 2 onto the power supply copper busbars.

[0056] S10: Magnetic bolt installation stage

[0057] Threaded fixing: Screw the magnetic bolt 1 (with external thread) into the original threaded hole of the power supply copper busbar, ensuring that its end face (including the positioning slot 103) faces outward.

[0058] S20: Quick-connect socket 2-stage mating phase

[0059] Insertion of insulating positioning pin 2022a: Align the insulating positioning pin 2022a of quick-connect socket 2 with the positioning slot 103 of magnetic bolt 1 and insert it to achieve mechanical positioning.

[0060] Magnetic conduction: Under the action of magnetic force, the annular contact part 2021 of the quick-connect socket 2 is attracted to the end face of the magnetic bolt 1, forming a tight metal contact surface (such as copper-copper bonding) to ensure low resistance conduction.

[0061] It should be noted that the distance between the power supply copper busbar and the box door of some power supply boxes is small. After installing the quick-connect socket 2, the box door may not be able to be closed. In this case, the quick-connect socket 2 can be placed in an unused space inside the power supply box. When the electrical equipment needs to draw power later, the box door can be opened and the quick-connect socket 2 can be plugged in on site.

[0062] II. Power Transmission Stage

[0063] S30: When the electrical equipment needs power, after opening the power supply box door, directly insert the plug of the electrical equipment into the quick-connect socket 2, and then connect it to the power supply copper busbar through the metal spring 201, the ring-shaped contact part 2021, and the magnetic bolt 1 in sequence.

[0064] S40: When the power equipment is finished and needs to be disconnected, simply unplug the power equipment or unplug the quick-connect socket 2 to cut off the power supply to the power equipment. The magnetic bolt 1 remains fixed to the copper busbar, and there is no need to repeatedly tighten the bolt.

[0065] The quick-connect socket provided by this invention effectively solves the efficiency and safety problems of traditional bolt connection methods through the coordinated design of magnetic bolt 1 and quick-connect socket 2.

[0066] First, the magnetic bolt 1 is pre-screwed into the threaded hole of the power supply copper busbar, maintaining the original structural compatibility. The quick-connect socket 2 uses an insulated positioning post 2022a to precisely align with the positioning slot 103 of the magnetic bolt 1. Combined with the magnetic attraction, the annular contact part 2021 tightly fits against the bolt end face, forming a stable conductive path. This design transforms the traditional tool-operated bolt connection into a plug-and-play operation that can be completed by hand, significantly improving operational efficiency and flexibility, and is particularly suitable for scenarios requiring frequent connection switching.

[0067] Secondly, in terms of safety, the operator does not need to directly contact the live copper busbar; the plugging and unplugging process is completed through an insulator, reducing the risk of electric shock. The quick-connect socket provided by this invention, while retaining the original structure of the power supply box, achieves faster and safer power supply for electrical equipment, providing a more convenient and reliable solution for power operation and maintenance.

[0068] Therefore, the quick-connect socket provided by the present invention can achieve an efficient, reliable and flexible connection between power equipment and power supply copper busbar while retaining the original threaded holes of the power supply copper busbar, so as to improve work efficiency and reduce work risks.

[0069] Generally, there are three power supply copper busbars, which are arranged in order as ground copper busbar 100a, neutral copper busbar 100b, and live copper busbar 100c, from top to bottom. Correspondingly, there are three socket power terminals, which are arranged in order as ground power terminal 202a, neutral power terminal 202b, and live power terminal 202c, from top to bottom. Therefore, the insertion and removal operations between the three magnetic screws 1 and the three socket power terminals can be completed in one go.

[0070] In this embodiment, the magnetic bolt 1 includes:

[0071] The bolt body 101 includes a threaded sleeve 1011 with external threads and a limiting ring 1012 located on the side of the threaded sleeve 1011 near the quick-connect socket 2; wherein the diameter of the limiting ring 1012 is larger than the diameter of the threaded sleeve 1011 to restrict the limiting ring 1012 from passing through the threaded hole.

[0072] A rubber-coated magnetic component 102 is fixed to one end of the threaded sleeve 1011 away from the limiting ring 1012, and is used for magnetic connection with the quick-connect socket 2.

[0073] Because the limiting ring 1012 has a circular structure, the magnetic bolt 1 can smoothly connect with the annular contact part 2021 of the quick-connect socket 2 regardless of the angle at which it is turned on the power supply copper busbar. However, designing the limiting ring 1012 as a circular structure creates a problem where tools such as box wrenches or adjustable wrenches cannot be used to turn the magnetic bolt 1. To solve the problem of turning the magnetic bolt 1, in this embodiment, the positioning slot 103 extends from the limiting ring 1012 toward the threaded sleeve 1011, and the bottom of the positioning slot 103 is provided with an internal hexagonal groove 104. Before inserting the quick-connect socket 2, an insulated hexagonal wrench can be used to reach into the internal hexagonal groove 104 to turn the magnetic bolt 1.

[0074] Optionally, the coated magnetic component 102 includes a first magnet 1021 and a first insulating coating 1022 covering the first magnet 1021; the insulating positioning post 2022a is provided with a second magnet 204 for magnetically connecting with the first magnet 1021.

[0075] In this embodiment, the quick-connect socket 2 further includes:

[0076] The socket housing 203 encloses and forms an internal space. The socket housing 203 has a plurality of panel socket holes 2031 for inserting the plug on the side away from the magnetic bolt 1, and a terminal mounting window for accommodating the power supply terminal of the socket on the side near the magnetic bolt 1.

[0077] The metal spring 201 is fixed in the internal space of the shell, and each panel socket 2031 is provided with two metal springs 201 arranged opposite to each other.

[0078] It should be noted that the socket housing 203, panel socket 2031, metal spring 201, and other structures are the same as existing socket structures, and will not be described in detail here. The focus of this invention is to add a power supply terminal to the socket based on the existing socket structure.

[0079] The socket power terminal includes a second insulating coating 2022 that connects the socket housing 203 and the annular power receiving part 2021;

[0080] The second insulating coating 2022 includes the insulating positioning post 2022a located inside the annular contact portion 2021, the outer coating ring 2022b located outside the annular contact portion 2021, and the annular connecting piece 2022c connecting the insulating positioning post 2022a and the outer coating ring 2022b.

[0081] Optionally, the annular connecting piece 2022c is provided with a plurality of through holes, and the annular electrical contact part 2021 is provided with an electrical contact post 2021a passing through the through holes. The electrical contact post 2021a is electrically connected to the corresponding metal spring piece 201 through a wire.

[0082] In this embodiment, the socket housing 203 is made of rigid plastic, the second insulating coating 2022 is made of silicone or rubber, and the annular contact portion 2021 is made of metal.

[0083] The socket housing 203, the second insulating coating 2022, and the annular contact part 2021 are connected by in-mold two-color injection molding. The circumferential surface of the second insulating coating 2022 is provided with an anti-detachment boss 2022d that protrudes into the socket housing 203, thereby improving the connection reliability between the second insulating coating 2022 and the socket housing 203.

[0084] Both the first insulating coating 1022 and the second insulating coating 2022 are high-temperature resistant materials to prevent the adhesive from melting due to heat at the electrical connection points.

[0085] In this embodiment, the electrical connection between the magnetic bolt 1 and the socket power terminal is mainly achieved by the contact between the annular end faces of the limiting ring 1012 and the annular power receiving part 2021. As long as the surface roughness of the annular end faces of the two meet the requirements, good electrical connection performance can be guaranteed, and there is no poor contact.

[0086] If the insulating positioning pin 2022a were also made a conductive component, it would increase the contact area between the magnetic bolt 1 and the socket's power terminal, thereby improving the rated current parameter. However, if the insulating positioning pin 2022a fits too tightly against the wall of the positioning slot 103, smooth insertion and removal would be difficult; if the fit is insufficient, poor contact could easily occur. Frequent poor contact could easily cause electric arcs or even fires, especially under high current conditions, posing a significant safety hazard. Therefore, in this invention, the insulating positioning pin 2022a is made an insulating component, used only for positioning and not for conduction.

[0087] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
