For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] Please refer to Figures 1 to 4 The large current bidirectional butt joint male head structure of an embodiment of the present application includes a plug assembly 10, the plug assembly 10 includes a plug piece 11, a connecting piece 12 installed on the plug piece 11, and a wire end piece 13 installed on the connecting piece 12 away from the plug piece 11 for connecting with a cable; the connecting piece 12 includes an interface part 120 sleeved on the plug piece 11 and threadedly connected with the plug piece 11, and a connecting part 121 installed on the interface part 120 away from the plug piece 11; the connecting part 121 is connected and fixed with the wire end piece 13. In the embodiment, the large current bidirectional butt joint male head structure is used for cooperating with a socket assembly 20.

[0025] The working principle of the large-current bidirectional butt joint male head structure of the utility model is as follows: in the cable connection end, the wire end piece 13 is connected with the cable, which conducts the current in the cable to the connecting piece 12; the reliable connection mode is adopted between the wire end piece 13 and the connecting part 121 of the connecting piece 12, which ensures that the current can be smoothly transmitted from the cable to the connecting piece 12; the interface part 120 of the connecting piece 12 is sleeved on the plug piece 11 and is connected through threads; not only mechanical stability is provided, but also good electrical connection is ensured; the current is conducted from the connecting part 121 of the connecting piece 12 to the interface part 120, and then is transmitted to the plug piece 11 through the close contact between the interface part 120 and the plug piece 11; the connection mode between the interface part 120 and the plug piece 11 is like a conductive bridge, which effectively conducts the current from the connecting piece 12 to the plug piece 11; the plug piece 11 outputs the current conducted from the connecting piece 12 after establishing the electrical connection; the conductive structure design inside the plug piece 11 enables the current to be evenly distributed on the surface (such as a socket) in contact with it, so as to ensure that the large current can be transmitted with lower impedance; for example, the conductive part of the plug piece 11 can adopt a multi-contact design or a large-area conductive metal sheet to increase the contact area, reduce the contact resistance and improve the current transmission efficiency.

[0026] Compared with the prior art, the large-current bidirectional butt joint male head structure of the utility model increases the contact area with the socket through the cooperation of the plug piece 11, the connecting piece 12 and the wire end piece 13, which can effectively reduce the contact resistance; the interface part 120 of the connecting piece 12 is connected with the plug piece 11 through threads, which effectively reduces the contact resistance, so that the impedance of the whole connecting structure is reduced, meeting the requirement of large-current transmission on low impedance; the connecting part 121 of the wire end piece 13 and the connecting piece 12 adopts a reliable connection mode, which ensures the smooth conduction of the current from the cable to the connecting piece 12; then the current is transmitted to the plug piece 11 through the close contact between the interface part 120 of the connecting piece 12 and the plug piece 11; the impedance in the transmission process of the current is reduced, compared with the impedance increase in the traditional connection mode due to factors such as wire quality, length and multiple connector connection points, the structure can effectively reduce the overall impedance.

[0027] Please refer to Figure 2 and Figure 3The wire end piece 13 includes a mounting portion 131 mounted on the connecting portion 121, and a wiring portion 132 mounted on the mounting portion 131 for connecting with the cable. The mounting portion 131 is tightly connected with the connecting portion 121 of the connecting piece 12 to provide a stable mounting basis for the wire end piece 13. For example, the mounting portion 131 can be firmly fixed on the connecting portion 121 by welding or crimping, etc., to avoid loosening due to external factors such as vibration, pulling, etc. during use, and to ensure that the electrical connection between the wire end piece 13 and the connecting piece 12 always remains in good condition and prevents poor contact. The wiring portion 132 is used to connect with the cable, and its diversified connection methods (such as crimping and screwing) have high reliability. It can ensure that the current is continuously and stably conducted from the cable to the wiring portion 132 during large current transmission, avoiding electrical failure due to loose connection. From the cable to the wiring portion 132, and then through the mounting portion 131 to the connecting piece 12, the parts are tightly connected to form an efficient current conduction channel.

[0028] The connecting portion 121 is a first flat connecting sheet, and the mounting portion 131 is a second flat connecting sheet arranged to cooperate with the first flat connecting sheet. The shape of the flat connecting sheet allows the current to be more evenly distributed during conduction. Compared with other shapes of connecting structures, the flat design can avoid the concentration of current in some local areas and reduce the risk of local overheating. For example, when a large current passes through, the current can flow uniformly on the surface of the entire flat connecting sheet, which helps to improve the performance and service life of electrical equipment, especially in the case of long-time transmission of large current, which can better ensure the stable transmission of current. The cooperation mode of the first flat connecting sheet and the second flat connecting sheet can make them tightly fit together, which is less likely to slide or loosen compared with other shapes of connecting structures (such as circular or irregular shapes). When the equipment is subjected to vibration, impact or frequent plugging, etc., the tight fit between the flat connecting sheets can maintain good mechanical connection and ensure the stability of electrical connection. For example, in industrial environments, electrical equipment is often affected by vibrations generated by machine operation, and the design of flat connecting sheets can effectively resist such vibrations and prevent loose connection.

[0029] The first flat connecting piece is provided with a threaded hole 133, and the second flat connecting piece is provided with a through hole 134 matched with the threaded hole 133; the plug assembly 10 further includes a bolt, which is screwed through the through hole 134 and the threaded hole 133. By screwing the first flat connecting piece and the second flat connecting piece together, a mechanically locked structure is formed; this connection method is more stable than simply relying on flat lamination; during equipment operation, whether subjected to vibration, impact, or thermal expansion and contraction due to temperature changes, bolt connection can effectively prevent loosening or displacement between the first flat connecting piece and the second flat connecting piece; for example, in an industrial environment, the equipment may be frequently subjected to vibration generated by machine operation, or jolt during transportation, and bolt connection can ensure that the connection between the wire head piece 13 and the connecting piece 12 remains tight, thereby maintaining good electrical connection; the threaded connection of the bolt can apply appropriate tightening force as needed; when the bolt is tightened, it will generate enough pressure between the first flat connecting piece and the second flat connecting piece, making them tightly fit; even under long-term use or harsh environmental conditions, the connection between the wire head piece 13 and the connecting piece 12 can be ensured not to fail easily; for example, in the outdoor new energy equipment aging test scene, in the face of wind, sun, rain, etc., the wire head piece 13 of the bolt connection can still work stably.

[0030] Please refer to Figure 3 and Figure 4 , the plug piece 11 includes a plug part 110 and a mating part 111 which is threadedly connected with the interface part 120. The mating part 111 of the plug piece 11 and the interface part 120 of the connecting piece 12 are threadedly connected, which provides strong mechanical stability; the threaded connection can tightly combine the plug piece 11 and the connecting piece 12, and effectively prevent loosening or separation between them when subjected to external forces (such as insertion and removal force, vibration or impact); for example, in the application scenario of frequently inserting and removing the plug assembly 10, the threaded connection structure can withstand the friction and tension during insertion and removal, ensuring that the connection between the plug piece 11 and the connecting piece 12 is always firm, thereby maintaining reliable electrical connection; when the equipment vibrates, the threaded connection can firmly fix the plug piece 11 and the connecting piece 12 together, avoiding loosening and poor contact due to vibration; for some new energy equipment aging test scenarios with extremely high connection stability requirements, this anti-vibration and anti-impact capability can ensure the smooth progress of the test process, reducing test errors or equipment damage caused by connection problems.

[0031] The interface part 120 includes a threaded interface 122 threadedly connected with the mating part 111, and a fixing sleeve 123 mounted on the threaded interface 122 away from the connecting part 121. The threaded interface 122 of the interface part 120 is threadedly connected with the mating part 111 of the plug member 11, which can provide stable mechanical connection and ensure the close combination of the plug member 11 and the connecting member 12. The fixing sleeve 123 is mounted on the threaded interface 122 away from the connecting part 121, which can play a reinforcing role. For example, during the operation of the equipment, when subjected to vibration, impact or accidental external force pulling, the fixing sleeve 123 can limit the relative displacement between the threaded interface 122 and the mating part 111, further enhance the firmness of the connection, prevent the loosening of the connection caused by external force, and thus ensure the mechanical stability of the entire plug assembly 10. The fixing sleeve 123 can assist in maintaining good electrical contact to some extent. When the equipment is affected by temperature changes and other factors during operation, the plug member 11 and the connecting member 12 may expand or contract due to heat. The fixing sleeve 123 can limit the small displacement between the threaded interface 122 and the mating part 111, ensure that the contact pressure between them remains within a suitable range, and thus maintain good electrical connection. It can effectively reduce the contact resistance and reduce power loss and heating.

[0032] The plug assembly 10 further includes a fastener 14 mounted outside the interface part 120 for fixing the connecting member 12, and the fixing sleeve 123 is clamped and mounted in the fastener 14. The fastener 14 is mounted outside the interface part 120 for fixing the connecting member 12, which can externally constrain the connecting member 12. When subjected to various external forces (such as vibration, impact, accidental pulling, etc.), it can be more stably maintained in the correct position. For example, in an industrial environment, the equipment is often subjected to continuous vibration generated by machine operation, and the fastener 14 can effectively prevent the connecting member 12 from displacing due to vibration, ensuring the integrity of the internal structure of the plug assembly 10 and the stability of the connection. The fixing sleeve 123 is clamped and mounted in the fastener 14, so that the fixing sleeve 123 and the fastener 14 cooperate to form a more powerful fixing system. The fixing sleeve 123 mainly acts on the threaded interface 122 of the interface part 120, while the fastener 14 focuses on fixing the entire connecting member 12. They work together to further enhance the mechanical stability of the plug assembly 10, making the connection between the components more closely and better resisting the destruction of the connection structure by external factors.

[0033] Please refer to Figure 3The plug assembly 10 further comprises a sealing member 15 mounted on the fastener 14. In many practical application scenarios, the plug assembly 10 can be exposed to complex environments; the presence of the sealing member 15 can effectively prevent moisture and dust from entering the interior of the plug assembly 10; for example, in the outdoor new energy equipment aging test scenario, rainwater, dew or dust can have adverse effects on electrical connections; by preventing these impurities from entering, problems such as short circuits caused by moisture or increased contact resistance caused by dust accumulation can be avoided, ensuring the electrical performance and service life of the plug assembly 10.

[0034] Referring to Figure 4 The plug assembly 10 is multiple, and the plug assembly 10 further comprises a support member 16 mounted on the fastener 14 for connecting and fixing multiple plug assemblies 10. The support member 16 can connect and fix these plug assemblies 10 together, so that they form a compact overall structure; for example, in a large new energy equipment aging test system, multiple lines with different functions need to be connected, and by arranging multiple plug assemblies 10 in an orderly manner through the support member 16, the internal space of the equipment can be effectively saved, space waste caused by scattered arrangement of plug assemblies 10 can be avoided, and a more reasonable space layout can be achieved; when multiple plug assemblies 10 are connected as a whole through the support member 16, only one installation operation is needed for the overall structure during equipment installation, instead of installing plug assemblies 10 one by one; this greatly improves the installation efficiency; at the same time, for wiring planning, maintenance personnel can more conveniently plan the cable path and connect the cables to multiple plug assemblies 10, so that the wiring is more neat and orderly, and safety hazards and management inconvenience caused by disordered cables are reduced.

[0035] The plug assembly 10 further comprises a gripping handle 17 mounted on the support member for assisting force. When connecting or disconnecting a large-current bidirectional butt joint male structure, the gripping handle 17 provides a convenient force application point; because large current transmission is involved, the plug assembly 10 can be relatively heavy, or a large force is required during plugging; the gripping handle 17 enables the operator to hold and apply sufficient plugging force more easily, and successfully completes the connection or separation of the plug assembly 10 and the socket assembly; for example, during the connection process of the new energy equipment aging test equipment, technicians can conveniently plug multiple plug assemblies 10 into corresponding sockets at the same time through the gripping handle 17, improving the operation efficiency; the presence of the handle enables the operator to better control the plugging direction and force of the plug assembly 10; in some scenarios with high connection accuracy requirements, such as compact internal space of the equipment, the plug and the socket need to be accurately aligned, and the gripping handle 17 can be used for more accurate operation, avoiding damage to the conductive part of the plug or the socket due to improper force.

[0036] The above merely expresses the preferred technical solutions of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
