Description

A male electrical connector, a female electrical connector and their assembly, an electrical appliance, a power supply device, and a spring component. Technical Field

[0001] This application relates to the field of power supply connection technology, and in particular to a male and female connector and their combination, electrical equipment, power supply equipment, and spring component. Background Technology

[0002] In related technologies, electrical connector male and / or electrical connector female are susceptible to high-frequency vibration under harsh operating conditions, which can cause relative misalignment between the components that form electrical conduction. This can lead to changes in the contact points of electrical conduction, making it easy to form edge contacts or point contacts. The contact area and the number of contact points decrease, resulting in a decrease in current conduction performance. The components that form electrical conduction may overheat or wear, thus affecting the service life of the electrical connector.

[0003] Summary of the Invention

[0004] To address the short lifespan of existing electrical connectors in the prior art, embodiments of this application provide a male connector, a female connector and their combination, an electrical device, a power supply device, and a spring component.

[0005] In a first aspect, embodiments of this application disclose an electrical connection female socket, which is used to mate with an electrical connection male socket, the electrical connection female socket comprising:

[0006] The female seat body has a receiving cavity; and

[0007] A spring member is partially disposed within the receiving cavity, and the spring member is used to engage with the conductive part of the electrical connection male socket to conduct current.

[0008] Wherein, at least a portion of the cross-section of the inner surface of the spring member in a direction substantially perpendicular to the depth direction of the receiving cavity is arc-shaped and bulges outward toward the center of the receiving cavity, such that when the conductive member is inserted into the receiving cavity along the depth direction of the receiving cavity, the outward bulge of the inner surface of the spring member can contact the conductive member to form electrical conduction.

[0009] Secondly, embodiments of this application disclose an electrical connector male, which is used to mate with the aforementioned electrical connector female, the electrical connector male comprising:

[0010] The main body of the public seat; and

[0011] A conductive element is disposed on the male seat body and extends outward from the male seat body, the conductive element being used to insert and cooperate with the spring member to conduct current.

[0012] Thirdly, embodiments of this application disclose an electrical connector assembly, including the aforementioned electrical female connector and the aforementioned electrical male connector.

[0013] Fourthly, embodiments of this application disclose an electrical device, including the aforementioned electrical connection female socket, the aforementioned electrical connection male socket, or the aforementioned electrical connector combination.

[0014] Fifthly, embodiments of this application disclose a power supply device for electrical connection with electrical equipment, the power supply device comprising:

[0015] Circuit boards; and

[0016] An electrical connection terminal, which is detachably mounted on the circuit board and electrically connected to the circuit board;

[0017] The electrical connection terminal includes one of the aforementioned electrical connection female and electrical connection male, and the electrical equipment includes the other of the aforementioned electrical connection female and electrical connection male.

[0018] Sixthly, embodiments of this application disclose a spring member applied to an electrical connection female seat, the spring member comprising:

[0019] Multiple spring assemblies are arranged to form a hollow cavity for receiving a conductive element of an electrical connector that mates with the electrical connector female. The inner surface of each spring assembly has an arc-shaped cross-section in a direction substantially perpendicular to the depth direction of the hollow cavity and protrudes outward toward the center of the hollow cavity, so that when the conductive element is inserted into the hollow cavity along the depth direction, the outward protrusion of the inner surface of the spring assembly can contact the conductive element to form electrical conductivity.

[0020] In this embodiment, at least a portion of the cross-section of the inner surface of the spring member of the electrical connector in a direction substantially perpendicular to the depth direction of the receiving cavity is arc-shaped and bulges outward toward the center of the receiving cavity. This allows the outward bulge of the inner surface of the spring member to contact the conductive member to form electrical conductivity when the conductive member is inserted into the receiving cavity along the depth direction of the receiving cavity. Even if the outward bulge forming electrical conductivity is relatively offset from the conductive member due to high-frequency vibration, the outward bulge and the conductive member can still maintain surface contact, avoiding the adverse effects caused by edge contact or point contact, and thus improving the service life of the electrical connector.

[0036] The electrical connection female and male connectors in this application embodiment are suitable for electrical connections in various scenarios, serving to connect or disconnect circuits. This is particularly relevant in the field of aircraft, where power is needed to supply power to the functional components. Due to the harsh operating conditions, higher requirements are placed on the electrical connection female and male connectors. It should be noted that the aircraft in this application embodiment includes both unmanned and manned aircraft. Taking unmanned aerial vehicles (UAVs) as an example, they are used in various fields such as agriculture, inspection, transportation, and aerial photography.

[0037] In related technologies, under harsh operating conditions (for example, unmanned aerial vehicles are easily affected by the vibration of their own power system or by the interference of the external environment during operation, resulting in high-frequency vibration), the electrical connection female and male components may become relatively misaligned. This causes changes in the contact points of the electrical connection, making it easy to form edge contacts or point contacts. The contact area and the number of contact points decrease sharply, resulting in a decrease in conductivity, overheating and wear of the electrical connection components, and thus affecting the service life of the electrical connection female and male.

[0038] In response, the embodiments of this application provide the following solutions.

[0039] This application provides an electrical connector 100, which can be used to mate with other electrical connectors. The electrical connector 100 includes: a connector body 1, which may have a receiving cavity 11; and a spring member 2, which is partially disposed in the receiving cavity 11. The spring member 2 is used to insert and mate with the conductive element 6 of the electrical connector 200 to conduct current. The inner surface of the spring member 2 has at least a portion of its cross-section in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, being arc-shaped and bulging outward toward the center of the receiving cavity 11, so that when the conductive element 6 is inserted into the receiving cavity 11 along the depth direction S1 of the receiving cavity 11, the outward bulge 22 of the inner surface of the spring member 2 can contact the conductive element 6 to form electrical conduction.

[0040] In this embodiment, at least a portion of the cross-section of the inner surface of the spring member 2 of the electrical connector 100 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is arc-shaped and protrudes outward toward the center of the receiving cavity 11. This is so that when the conductive member 6 is inserted into the receiving cavity 11 along the depth direction S1, the outward protrusion 22 of the inner surface of the spring member 2 can contact the conductive member 6 to form electrical conduction. The outward protrusion 22 and the conductive member 6 form arc surface contact. Even if the outward protrusion 22 forming electrical conduction is relatively offset from the conductive member 6 due to the influence of high frequency vibration, the outward protrusion 22 and the conductive member 6 can still maintain surface contact, avoiding the adverse effects caused by edge contact or point contact, which is beneficial to improving the service life of the electrical connector.

[0041] As shown in Figure 1, the electrical connection female socket 100 may include a female socket body 1 and a spring member 2. The female socket body 1 has a receiving cavity 11, and the spring member 2 is partially disposed in the receiving cavity 11. The spring member 2 serves as a first plug-in member for plugging and engaging with the second plug-in member, namely the conductive member 6, of the electrical connection male socket 200. The plugging and engaging of the spring member 2 and the conductive member 6 can conduct current.

[0042] In this embodiment, the female connector body 1 can be the main structure of the electrical connection female connector 100. The female connector body 1 has a receiving cavity 11, which is a cavity with one end open. The cavity can be in a regular shape, for example, a cylindrical shape, or the cavity can be close to a cylindrical shape. The receiving cavity 11 can be used to receive the spring member 2 and the conductive member 6 of the electrical connection male connector 200.

[0043] In this embodiment, the spring member 2 has elastic deformation capability, which can accommodate the dimensional tolerances of the conductive component 6 during processing, as well as the tolerances caused by thermal expansion and contraction. The spring member 2 has a conductive function. The spring member 2 is disposed within the receiving cavity 11.

[0044] In this embodiment, the spring member 2 has an inner surface and an outer surface. The outer surface is arranged close to the inner wall of the receiving cavity 11, and the outer surface can be far away from the inner wall of the receiving cavity 11.

[0045] The electrical connector female 100 and the electrical connector male 200 mate together to form an electrical connector. In practical applications, the electrical connector assembly may experience twisting relative to the conductive element 6, or vice versa, during insertion, removal, or vibration. In this application, at least a portion of the cross-section of the inner surface of the spring member 2 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is arc-shaped and bulges outward toward the center of the receiving cavity 11. That is, a portion of the inner surface protrudes away from the inner wall of the receiving cavity 11 to form an outward protrusion 22. In this way, even if the spring member 2 and the conductive element 6 twist relative to the initial insertion position, the outward protrusion 22 of the inner surface of the spring member 2 can still make good contact with the conductive element 6 to form good electrical conductivity, thereby improving the overall service life of the electrical connector.

[0046] In some embodiments, the protrusion 22 protrudes radially along the receiving cavity 11, i.e., in the direction of the arrow in FIG3. When the spring member 2 and the conductive member 6 are inserted, the conductive member 6 can press the protrusion 22 radially along the receiving cavity 11 so that the spring member 2 and the conductive member 6 can make close contact and achieve good electrical conduction.

[0047] In some embodiments, as shown in FIG2, the spring member 2 can be enclosed to form a cage-like structure, which is used to accommodate the conductive member 6.

[0048] In the embodiments of this application, the cross-section of the cage structure can be a ring structure or a near-ring structure, etc., which can be set according to actual needs. The embodiments of this application do not make specific limitations in this regard.

[0049] Optionally, the cage structure has elastic deformation capability or plastic deformation capability, so that the cage structure can undergo appropriate deformation, and the spring component 2 can still be tightly matched with the conductive component 6 even during high-frequency vibration.

[0050] Optionally, when the cage structure is not inserted into the conductive member 6, the cage structure is an hourglass shape with large diameters at both ends and a small diameter in the middle. When the cage structure is inserted into the conductive member 6, the middle part of the cage structure expands away from the center of the receiving cavity 11 under the abutment action of the conductive member 6. That is, when the conductive member 6 is inserted into the cage structure, the middle part of the cage structure is compressed and deformed. At the same time, the elastic deformation of the middle part of the cage structure will apply an elastic restoring force to the conductive member 6, thereby ensuring close contact between the spring member 2 and the conductive member 6.

[0051] Optionally, the spring member 2 is detachably disposed within the receiving cavity 11, facilitating individual replacement or maintenance of both, and reducing the cost of the electrical connection female 100.

[0052] Optionally, the spring member 2 is detachably disposed within the receiving cavity 11 in a form-fit manner to minimize unnecessary gaps. Optionally, the spring member 2 is detachably disposed within the receiving cavity 11 in a force-fit manner to minimize stress caused by assembly. In practical applications, the spring member 2 and the receiving cavity 11 may only be form-fitted, or the spring member 2 and the receiving cavity 11 may only be force-fitted, or the spring member 2 and the receiving cavity 11 may be both form-fitted and force-fitted.

[0053] In some embodiments, multiple spring members 2 can be arranged along the depth direction S1 of the receiving cavity 11, and the multiple spring members 2 can be connected together by bridging to form a conductive path.

[0054] In some embodiments, the spring member 2 can be a torsion spring, and the multiple spring assemblies 21 in the spring member 2 spirally surround the conductive element 6 to form multiple independent current paths, which improves the contact reliability. Moreover, the spiral surrounding method can increase the contact area between the inner surface of the spring assembly 21 and the conductive element 6, which can improve the current carrying capacity between the spring member 2 and the conductive element 6.

[0055] In some embodiments, the spring member 2 may include a plurality of spring assemblies 21, which may be enclosed to form the spring member 2. The plurality of spring assemblies 21 are arranged separately, so that the elastic deformation capability of the spring assembly 21 is better, which facilitates increasing the contact area between the spring member 2 and the conductive element 6 and improving the current carrying capacity.

[0056] Optionally, multiple spring assemblies 21 are arranged circumferentially along the receiving cavity 11 to facilitate the formation of a hollow structure for the spring members 2 to be inserted into the conductive element 6.

[0057] Optionally, multiple spring assemblies 21 are arranged at equal intervals along the circumference of the receiving cavity 11. This improves the structural stability of the spring member 2 and enhances the uniformity of force distribution between the spring member 2 and the conductive element 6, ensuring good contact at all contact points between the spring member 2 and the conductive element 6. The spacing density between the multiple spring assemblies 21...

[0058] In practical applications, multiple spring assemblies 21 can also be arranged at non-equal intervals along the circumference of the receiving cavity 11, and this application embodiment does not specifically limit this.

[0059] Optionally, the inner surface of the spring assembly 21 has an arc-shaped cross section in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, and protrudes outward toward the center of the receiving cavity 11, so that when the conductive member 6 is inserted into the receiving cavity 11 along the depth direction S1 of the receiving cavity 11, the outward protrusion 22 of the inner surface of the spring assembly 21 can contact the conductive member 6 to form electrical conduction.

[0060] In this embodiment, since the inner surface of the spring assembly 21 has an arc-shaped cross section in the direction S2 that is substantially perpendicular to the depth direction S1 of the receiving cavity 11, the spring assembly 21 can make surface contact with the conductive element 6. Even if high-frequency vibration causes a positional shift between the spring assembly 21 and the conductive element 6, the spring assembly 21 and the conductive element 6 can always maintain surface contact, which can improve the contact quality between the spring assembly 21 and the conductive element 6, thereby improving the current carrying capacity between the spring assembly 21 and the conductive element 6.

[0061] Figure 4 illustrates the contact diagrams between the spring assembly 21 and the conductive element 6 under various states. Figure 4(a) shows the contact state when there is no positional offset between the spring assembly 21 and the conductive element 6. Figures 4(b) and 4(c) show two different contact states when there is a positional offset between the spring assembly 21 and the conductive element 6.

[0062] Optionally, as shown in Figures 2 and 3, the cross-section of the inner surface of the spring assembly 21 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is substantially arc-shaped, so that the contact area between the spring assembly 21 and the conductive element 6 can remain unchanged, which can further improve the contact quality and current carrying capacity between the spring assembly 21 and the conductive element 6.

[0063] Optionally, the cross-section of the spring assembly 21 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is arc-shaped, so that the spring assembly 21 as a whole is an arc-shaped structure, such as a cylindrical grid bar. The regular shape of the spring assembly 21 as a whole is beneficial to its preparation and forming.

[0064] Optionally, the cross-section of the inner surface of the spring assembly 21 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is substantially elliptical. This ensures that the spring assembly 21 and the conductive element 6 maintain surface contact at all times, thereby improving the contact quality and current carrying capacity between the spring assembly 21 and the conductive element 6.

[0065] In the embodiments of this application, the cross-section of the inner surface of the spring assembly 21 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, can be an arc shape, or it can be close to an ellipse, or other irregular arc segments, etc.

[0066] Optionally, the central angle corresponding to the arc shape can be 45 to 180 degrees, which can meet the surface contact requirements between the spring assembly 21 and the conductive element 6 during high-frequency vibration.

[0067] In practical applications, the central angle corresponding to the arc can be 45 degrees, 50 degrees, 110 degrees, 150 degrees, 175 degrees, or 180 degrees, etc.

[0068] Optionally, the spring assembly 21 has opposing head and tail ends along its length, and the virtual straight line connecting the head and tail ends intersects the axis of the receiving cavity 11 in a non-plane manner, so that the spring assembly 21 can be in a torsional shape. The axis of the receiving cavity 11 is located in the depth direction S1 of the receiving cavity 11, so that the cavity of the receiving cavity 11 can be a cylindrical structure.

[0069] Optionally, as shown in Figure 2, the specific angle θ formed between the virtual straight line connecting the endpoints of the first end and the end of the last end and the axis of the receiving cavity 11 is an acute angle, so that the torsion angle of the spring assembly 21 can be an acute angle.

[0070] Optionally, the spring assembly 21 is twisted into a spiral shape relative to the axis of the receiving cavity 11 to optimize the contact area between the spring assembly 21 and the conductive element 6.

[0071] Furthermore, the specific included angle θ can be less than or equal to 45 degrees, and the current carrying capacity between the spring assembly 21 and the conductive element 6 can be improved by optimizing the torsion angle of the spring assembly 21.

[0072] Optionally, the specific included angle θ corresponding to each of the multiple spring assemblies 21 can be basically the same, which helps to ensure that the force between the multiple spring assemblies 21 and the conductive element 6 is basically uniform, so that the spring component 2 and the conductive element 6 have good contact and can improve the current carrying capacity between the spring component 2 and the conductive element 6.

[0073] Optionally, the spring assembly 21 can be made of an elastic conductive material, so that the spring assembly 21 can satisfy both the ability to generate elastic deformation and the ability to conduct current in contact with the conductive part 6.

[0074] In the embodiments of this application, the elastic conductive material can be copper or copper-based materials, etc.

[0075] Optionally, the lengths of the multiple spring assemblies 21 are basically the same, which helps to ensure the structural regularity and structural stability of the spring component 2.

[0076] In this embodiment, the current-carrying capacity of the electrical connector assembly is improved by optimizing the design of the spring component 2. The inner surface of the spring component 21 is preferentially designed as an arc surface; that is, the cross-section of the spring component 21 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is arc-shaped. This allows the spring component 21 to make arc-shaped contact with the conductive element 6, reducing wear between them and improving the overall lifespan of the electrical connector assembly. Furthermore, the spring component 21 can be twisted at any angle within 90 degrees, enabling it to achieve a torsion spring structure, which further enhances the current-carrying capacity of the electrical connector assembly.

[0077] In practical applications, contact area is negatively correlated with impedance, temperature rise, and pressure, while conductivity is positively correlated with contact area. In this application, the spring member 2 is in surface contact with the conductive element 6, resulting in a larger contact area. Therefore, the corresponding impedance and temperature rise are smaller, making it less likely for the conductive element 6 to suffer overheating damage; the corresponding pressure is also smaller, resulting in less pressure on the conductive element 6, thus making the conductive element 6 more wear-resistant; and the improved conductivity of the conductive element 6 results in better current carrying capacity of the electrical connector.

[0078] In this embodiment, the overall contact area between the spring component 2 and the conductive element 6 is increased by the overall torsional shape of the spring component 2; combined with the surface contact between the individual spring assembly 21 and the conductive element 6, the individual contact area between the spring assembly 21 and the conductive element 6 is increased; the combined use of these two measures can alleviate the poor contact caused by the relative offset between the spring component 2 and the conductive element 6, thereby enhancing the conductivity and wear resistance between the spring component 2 and the conductive element 6, avoiding overheating damage, and improving the service life and environmental adaptability of the electrical connection female socket 100 and the electrical connection male socket 200.

[0079] In some embodiments of this application, the cavity 11 has a limiting structure 3 inside to limit the insertion of the conductive element 6. This allows the electrical connector assembly formed by the mating of the female connector 100 and the male connector 200 to achieve zero gap in the direction S2, which is substantially perpendicular to the depth direction S1 of the cavity 11. Due to the zero-gap design, the mated electrical connector assembly can achieve a stable following and mating state in all directions of the horizontal plane, i.e., in the direction S2, which is substantially perpendicular to the depth direction S1 of the cavity 11, under high-frequency vibration. Therefore, stable force is achieved between the spring member 2 and the conductive element 6 under high-frequency vibration in the horizontal direction, avoiding short-term abnormal impacts on the spring member 2 and the conductive element 6, and effectively improving the overall service life of the electrical connector assembly.

[0080] Optionally, a limiting structure 3 may be provided at the upper end of the cavity 11; a limiting structure 3 may be provided at the lower end of the cavity 11; or a limiting structure 3 may be provided at both the upper and lower ends of the cavity 11 to achieve double-end limiting.

[0081] Optionally, the limiting structure 3 can be a limiting design of the receiving cavity 11 itself; the limiting structure 3 can also be an additional limiting structure set on the receiving cavity 11.

[0082] Optionally, the limiting structure 3 abuts against the inserted conductive element 6 to limit its movement, which can improve the reliability and stability of limiting the conductive element 6.

[0083] Optionally, the limiting structure 3 is used to limit the conductive element 6 axially and / or radially, which can effectively reduce the phenomenon of the conductive element 6 moving relative to the receiving cavity 11 and improve the good contact between the spring member 2 and the conductive element 6.

[0084] In the embodiments of this application, the limiting structure 3 may limit the conductive element 6 axially only, or it may limit the conductive element 6 radially only, or it may limit the conductive element 6 both axially and radially at the same time.

[0085] Optionally, the limiting structure 3 includes a limiting groove, which can be used to hold the conductive element 6 in place to prevent the conductive element 6 from moving relative to the receiving cavity 11. The limiting groove can be located at the opening of the receiving cavity 11 or at one end of the receiving cavity 11 away from the opening.

[0086] Optionally, the diameter of the limiting groove is smaller than the diameter of the receiving cavity 11, so that the limiting groove is recessed within the inner wall of the receiving cavity 11, which facilitates the limiting groove to limit the conductive component 6.

[0087] Optionally, the limiting groove may include any of the following: annular groove, stepped groove or inclined groove, which can improve the structural diversity of the limiting groove, and thus improve the diversity of the limiting structure 3 to limit the conductive element 6.

[0088] The electrical connection female socket 100 described in this application embodiment has at least the following advantages:

[0089] In this embodiment, at least a portion of the cross-section of the inner surface of the spring member 2 of the electrical connector 100 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, is arc-shaped and protrudes outward toward the center of the receiving cavity 11. This allows the outward protrusion 22 of the inner surface of the spring member 2 to contact the conductive member 6 to form electrical conductivity when the conductive member 6 is inserted into the receiving cavity 11 along the depth direction S1. The outward protrusion 22 and the conductive member 6 form an arc-shaped contact. Even if the outward protrusion 22 and the conductive member 6 are relatively offset due to high-frequency vibration, the outward protrusion 22 and the conductive member 6 can still maintain surface contact, avoiding the adverse effects caused by edge contact or point contact, and thus improving the service life of the electrical connector.

[0090] Secondly, this application also discloses an electrical connection male socket 200, which can be used to cooperate with the electrical connection female socket 100 in the aforementioned embodiments. The electrical connection male socket 200 includes: a male socket body 2; and a conductive member 6, which is disposed on the male socket body 2 and extends outward from the male socket body 2. The conductive member 6 is used to insert and cooperate with the spring member 2 to conduct current.

[0091] In this embodiment, the electrical connector male socket 200 includes a male socket body 2 and a conductive element 6. The male socket body 2 is the main structure of the electrical connector male socket 200. The conductive element 6 can be disposed on the male socket body 2. The conductive element 6 can extend outward from the male socket body 2, that is, the conductive element 6 protrudes from the male socket body 2. The conductive element 6 can have conductivity so that the conductive element 6 can be inserted and cooperate with the spring member 2 in the aforementioned electrical connector female socket 100 to conduct current.

[0092] In this embodiment, the conductive element 6 extends outward from the male body 2. The extension direction of the conductive element 6 can be consistent with the depth direction S1 of the receiving cavity 11, so that the conductive element 6 can be inserted into the receiving cavity 11 along the depth direction S1 of the receiving cavity 11 and engage with the spring member 2 inside the receiving cavity 11. Furthermore, the conductive element 6 and the spring member 2 are in surface contact, and current can be conducted between them. The extension length of the conductive element 6 can be less than or equal to the depth of the receiving cavity 11.

[0093] In this embodiment, the shape of the conductive element 6 can be adapted to the shape of the spring member 2 to facilitate the insertion of the conductive element 6 and the spring member 2. For example, the spring member 2 is a cage-like structure, and the conductive element 6 can be a columnar structure. Compared with the "blade"-shaped conductive element in related technologies, the columnar structure has a larger current-carrying area and can carry a larger current.

[0094] Optionally, the conductive element 6 is basically cylindrical, which facilitates the insertion and good contact between the conductive element 6 and the spring component 2.

[0095] Optionally, the electrical connector 200 further includes a limiting member 7, which limits the displacement of the conductive member 6 relative to the receiving cavity 11 when the conductive member 6 is inserted into the receiving cavity 11 along the depth direction S1 of the receiving cavity 11.

[0096] In this embodiment, the limiting member 7 can limit the displacement of the conductive member 6 relative to the receiving cavity 11, thereby limiting the offset between the conductive member 6 and the spring member 2. This can prevent poor contact between the conductive member 6 and the spring member 2 and ensure the current flow capacity between the conductive member 6 and the spring member 2.

[0097] In this embodiment, the limiting member 7 can be fixedly connected to the conductive member 6, and the limiting member 7 can be limited and cooperated with the inner wall of the receiving cavity 11. By limiting the relative movement between the limiting member 7 and the receiving cavity 11, the relative movement between the conductive member 6 and the receiving cavity 11 is limited.

[0098] Optionally, the limiting member 7 restricts the displacement of the conductive member 6 relative to the receiving cavity 11 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, by eliminating gaps, so as to effectively prevent the conductive member 6 from shifting relative to the spring member 2 and ensure the current flow capacity between the conductive member 6 and the spring member 2.

[0099] In this embodiment, when the conductive member 6 is inserted into the receiving cavity 11, the limiting member 7 can be tightly fitted with the inner wall of the receiving cavity 11, that is, the limiting member 7 and the receiving cavity 11 are fitted with zero clearance, so that the limiting member 7 cannot be displaced relative to the receiving cavity 11 in the direction S2 which is substantially perpendicular to the depth direction S1 of the receiving cavity 11, thereby limiting the displacement of the conductive member 6 relative to the receiving cavity 11 in the direction S2 which is substantially perpendicular to the depth direction S1 of the receiving cavity 11.

[0100] Optionally, the limiting member 7 protrudes from the outer peripheral surface of the conductive member 6, which can limit the outer periphery of the conductive member 6 to eliminate radial clearance during assembly and improve the reliability of limiting the displacement of the conductive member 6 relative to the receiving cavity 11 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11.

[0101] Furthermore, the limiting member 7 can cover the outer periphery of the conductive member 6, so that the limiting member 7 can be a ring structure, which can improve the reliability of limiting the conductive member 6 to move relative to the receiving cavity 11 in the direction S2, which is substantially perpendicular to the depth direction S1 of the receiving cavity 11.

[0102] In other cases, the limiting member 7 may also include multiple protrusions, which may be spaced apart along the outer peripheral surface of the conductive member 6. Furthermore, the multiple protrusions may also be evenly spaced along the outer peripheral surface of the conductive member 6.

[0103] Optionally, the limiting member 7 is made of wear-resistant material. In this way, after the conductive member 6 is repeatedly inserted into the spring member 2 in the receiving cavity 11, the wear of the limiting member 7 can be reduced and the service life of the limiting member 7 can be improved.

[0104] Furthermore, the limiting component 7 can be made of metal or plastic, giving the limiting component 7 more material options.

[0105] Optionally, the limiting member 7 can be located at the bottom of the conductive member 6 near the male seat body 2, or the limiting member 7 can be located at the top of the conductive member 6 away from the male seat body 2, which makes the setting position of the limiting member 7 more selective and can improve the convenience of arranging the limiting member 7.

[0106] In practical applications, the limiting component 7 can be set in a suitable position according to process requirements.

[0107] In some alternative embodiments, there can be multiple conductive elements 6, and the multiple conductive elements 6 can be distributed in an array.

[0108] In this embodiment, multiple conductive elements 6 are arranged in an array, which can improve the uniformity of force on the male seat body 2.

[0109] In the embodiments of this application, the number of conductive elements 6 corresponds one-to-one with the number of receiving cavities 11. In some cases, the number of conductive elements 6 corresponds one-to-one with the number of spring members 2, and one conductive element 6 can be plugged into one spring member 2; in other cases, the number of conductive elements 6 is greater than the number of spring members 2, for example, two spring members 2 are installed in one receiving cavity 11, and one conductive element 6 can correspond to two spring members 2.

[0110] Optionally, the multiple conductive elements 6 are symmetrically distributed with respect to the length and / or width of the male seat body 2, which can further improve the uniformity of force distribution on the male seat body 2.

[0111] Furthermore, the number of conductive elements 6 can be even, which facilitates the reasonable arrangement of the positions of multiple conductive elements 6, so as to achieve a symmetrical distribution of multiple conductive elements 6 relative to the length and / or width direction of the male body 2.

[0112] As shown in Figures 5 and 7, the number of conductive parts 6 can be four, which can realize the four conductive parts 6 and four spring members 2 to conduct current, effectively ensuring the current carrying capacity between the electrical connection male socket 200 and the electrical connection female socket 100.

[0113] In some alternative embodiments, as shown in Figure 6, the interior of the conductive element 6 can be a hollow cavity 61, which helps reduce the weight of the conductive element 6 and thus the overall weight of the electrical connector 200, making it easier to apply the electrical connector 200 in scenarios with strict weight requirements. Especially in the application scenario of unmanned aerial vehicles, the overall load restricts the flight maneuverability and endurance. The method of making the interior of the conductive element 6 a hollow cavity 61 can reduce the pressure on the overall load of the vehicle.

[0114] Optionally, the end of the conductive element 6 away from the male body 2 is a sealed structure, which can improve the convenience and safety of inserting the conductive element 6 into the receiving cavity 11, and can avoid problems such as the introduction of foreign objects and dirt by the open structure.

[0115] In practical applications, a hollow cavity 61 can be set inside the conductive component 6 through processes such as cold heading or stamping, so that the conductive component 6 achieves a hollow effect. Then, through spinning or hot working, a secondary sealing is achieved, so that the end of the conductive component 6 away from the male seat body 2 is a sealed structure, making the conductive component 6 a design structure with a seamless exterior and a hollow interior.

[0116] Optionally, the hollow cavity 61 can be a regular shape, which can improve the convenience and reliability of processing the hollow cavity 61.

[0117] Furthermore, the hollow cavity 61 can be a cylinder, which facilitates the processing of the hollow cavity 61.

[0118] Optionally, the hollow cavity 61 can be of an irregular shape, which facilitates increasing the structural diversity of the hollow cavity 61.

[0119] Optionally, the radial dimension of the hollow cavity 61 at the end closer to the male seat body 2 is smaller than the radial dimension at the end farther from the male seat body 2, so that the closer the conductive element 6 is to the male seat body 2, the higher the structural strength, which can ensure the connection strength between the conductive element 6 and the male seat body 2.

[0120] Optionally, the cross-sectional shape of the hollow cavity 61 in the depth direction S1 of the accommodating cavity 11 is basically an inverted trapezoid.

[0121] In this embodiment, the radial dimension of the hollow cavity 61 gradually decreases from the end of the conductive element 6 away from the male seat body 2 to the end closer to the male seat body 2, and the structural strength of the conductive element 6 gradually increases, so as to ensure the connection strength between the conductive element 6 and the male seat body 2.

[0122] In this application, the conductive element 6 can be a metal component to ensure good current conduction capacity. Metal components are typically heavy. By incorporating a hollow cavity 61 inside the conductive element 6, its weight can be reduced, preventing it from significantly impacting the overall product weight. This facilitates the application of electrical connectors in products with weight constraints, such as drones. Furthermore, incorporating a hollow cavity 61 allows for a hollow design of the conductive element 6, achieving weight reduction without altering its external dimensions. This balances the lifespan and weight of the electrical connector assembly, resulting in a product that achieves good weight reduction with minimal changes in current conduction capacity. In this application, the dimensions of the hollow cavity 61 and the thickness of the conductive element 6 can be adjusted to achieve different weight reduction effects and maintain a balance between the current conduction capacity and weight of the conductive element 6.

[0123] In some embodiments of this application, the conductive element 6 may include a multilayer material, which may include a first layer and a second layer, with the first layer covering the outer layer of the second layer, and the materials of the first layer and the second layer being different.

[0124] Optionally, the first layer covers the outer layer of the second layer, so that the first layer can protect the second layer, avoiding wear and reduced conductivity caused by repeated insertion and removal or vibration conditions, thereby extending the overall service life of the conductive component 6.

[0125] Optionally, the first layer has a higher hardness than the second layer, making the first layer more wear-resistant than the second layer. Even under repeated insertion and removal or vibration conditions, the harder first layer is not easily worn. Even if the first layer is worn away after a period of time, it will not affect the normal operation of the second layer, which is the main conductive component, thus effectively extending the overall service life of the conductive component 6.

[0126] Optionally, the first layer has a current-conducting function. Since the first layer is on the outer layer, it is in contact with the spring member 2, which enables the conductive member 6 to conduct electricity with the spring member 2.

[0127] Optionally, the material of the second layer may include at least one of the following: nickel, chromium or palladium, so that the second layer can also have a current-carrying function, effectively ensuring the current-carrying capacity between the electrical connection male socket 200 and the electrical connection female socket 100.

[0128] In some alternative embodiments of this application, the electrical connection male connector 200 may further include a guide 8, the guide 8 and the conductive element 6 are disposed on the same side of the male connector body 2, and the guide 8 and the conductive element 6 are spaced apart.

[0129] In this embodiment, the guide 8 and the conductive element 6 are located on the same side of the male body 2. The guide 8 serves as a guide to help the conductive element 6 be smoothly inserted into the receiving cavity 11. The guide 8 and the conductive element 6 are spaced apart to avoid interference between them.

[0130] In practical applications, the female body 1 of the electrical connection female socket 100 may also be provided with a first receiving groove 12, which can cooperate with the guide member 8 to accommodate the guide member 8.

[0131] Optionally, there may be multiple guide members 8, which are arranged in an array to facilitate uniform force distribution on the male seat body 2.

[0132] Optionally, the multiple guide members 8 are symmetrically distributed with respect to the length and / or width of the male seat body 2, which can further improve the uniformity of force distribution on the male seat body 2.

[0133] Furthermore, the number of guide members 8 can be two, which facilitates the symmetrical distribution of the guide members 8.

[0134] Optionally, the guide 8 is located on the side of the conductive element 6 away from the center of the male seat body 2, which facilitates the reasonable layout of the positions of the guide 8 and the conductive element 6.

[0135] Optionally, both the guide 8 and the conductive element 6 extend outward along the male body 2, with the extension length of the guide 8 being greater than that of the conductive element 6. In this way, when the electrical connection male 200 and the electrical connection female 100 are engaged, the guide 8 contacts the electrical connection female 100 first, playing a guiding role, which facilitates the convenience and reliability of inserting the conductive element 6 into the receiving cavity 11.

[0136] Optionally, the guide 8 further has a flow guiding function, which can improve the flow capacity between the electrical connection male socket 200 and the electrical connection female socket 100.

[0137] Optionally, the outer surface of the guide member 8 has a guide groove or guide teeth, which can guide and cooperate with the electrical connection female 100 to improve the reliability of assembling the electrical connection male 200 and the electrical connection female 100. And / or, the end of the guide member 8 away from the male body 2 is conical, which can improve the guiding effect of the guide member 8 and improve the reliability of assembling the electrical connection male 200 and the electrical connection female 100.

[0138] Optionally, the electrical connection male connector 200 also includes a signal transmission element 91, which and the conductive element 6 are located on the same side of the male connector body 2 and are spaced apart.

[0139] In this embodiment, the signal transmission element 91 can contact and engage with the electrical connection female socket 100, enabling signal transmission between the electrical connection male socket 200 and the electrical connection female socket 100. The signal transmission element 91 and the conductive element 6 are located on the same side of the male socket body 2, facilitating simultaneous electrical conduction between the conductive element 6 and the spring member 2 within the receiving cavity 11, and electrical connection between the signal transmission element 91 and the electrical connection female socket 100. The signal transmission element 91 and the conductive element 6 are spaced apart to avoid interference between them.

[0140] In practical applications, the female body 1 of the electrical connection female socket 100 may also be provided with a second receiving groove 13, and the signal transmission component 91 can be inserted into the second receiving groove 13 to achieve electrical conduction.

[0141] Optionally, both the signal transmission element 91 and the conductive element 6 extend outward along the male body 2, with the extension length of the signal transmission element 91 being less than the extension length of the conductive element 6.

[0142] In this embodiment, during the assembly of the male electrical connector 200 and the female electrical connector 100, i.e., when assembling the electrical connector, the conductive element 6 first contacts the female electrical connector 100, and then the signal transmission element 91 contacts the female electrical connector 100. During the separation of the male electrical connector 200 and the female electrical connector 100, i.e., when disassembling the electrical connector, the signal transmission element 91 first separates from the female electrical connector 100, and then the conductive element 6 separates from the female electrical connector 100. The different performance and requirements of the electrical connector during assembly and disassembly can be achieved by adjusting the height difference between the signal transmission element 91 and the conductive element 6.

[0143] Optionally, both the signal transmission element 91 and the guide element 8 extend outward along the male seat body 2, and the extension length of the signal transmission element 91 is less than the extension length of the guide element 8.

[0144] In this embodiment of the application, when assembling the electrical connector, the guide 8 first contacts the electrical connection female 100, and then the signal transmission component 91 contacts the electrical connection female 100. This allows the guide 8 to first play a limiting role, which can improve the convenience and reliability of assembling the signal transmission component 91 with the electrical connection female 100.

[0145] Optionally, the number of signal transmission components 91 can be multiple.

[0146] Furthermore, the number of signal transmission components 91 can be three, allowing for a reasonable arrangement of the number of signal transmission components 91 to meet the performance requirements of the electrical connector.

[0147] Optionally, the signal transmission element 91 is located on the side of the conductive element 6 near the center of the male body 2, which facilitates the reasonable arrangement of the positions of the signal transmission element 91 and the conductive element 6.

[0148] Furthermore, the signal transmission component 91 can be located at the center of the main body 2.

[0149] Optionally, the signal transmission component 91 can also be located on the side of the guide 8 near the center of the male seat body 2, so that the relative positions of the signal transmission component 91 and the guide 8 can be flexibly adjusted.

[0150] Optionally, the electrical connection male connector 200 may also include an in-place detection element 92, which and the conductive element 6 are located on the same side of the male connector body 2 and are spaced apart.

[0151] In this embodiment, after the in-position detection element 92 makes contact with the electrical connection female socket 100 and conducts electricity, the system can determine that the electrical conduction of the conductive element 6 and the spring member 2 has entered a stable state, and power supply and other execution actions can be performed. The in-position detection element 92 and the conductive element 6 are spaced apart to avoid interference between them.

[0152] In practical applications, the female body 1 of the electrical connection female socket 100 can also be provided with a third receiving groove 14, and the in-position detection element 92 can be inserted into the third receiving groove 14 to achieve electrical conduction.

[0153] Optionally, both the in-situ detection element 92 and the conductive element 6 extend outward along the male seat body 2, and the extension length of the in-situ detection element 92 is less than the extension length of the conductive element 6.

[0154] In this embodiment, during the assembly of the electrical connector, the conductive element 6 first contacts the electrical connector female 100, and then the in-place detection element 92 contacts the electrical connector female 100; during the disassembly of the electrical connector, the in-place detection element 92 first separates from the electrical connector female 100, and then the conductive element 6 separates from the electrical connector female 100. The different performance and requirements of the electrical connector during assembly and disassembly can be achieved by adjusting the height difference between the in-place detection element 92 and the conductive element 6.

[0155] Optionally, both the in-situ detection element 92 and the guide element 8 extend outward along the male seat body 2, and the extension length of the in-situ detection element 92 is less than the extension length of the guide element 8.

[0156] In this embodiment, when assembling the electrical connector, the guide 8 first contacts the electrical connector 100, and then the in-place detection element 92 contacts the electrical connector 100. This allows the guide 8 to first play a limiting role, which can improve the convenience and reliability of assembling the in-place detection element 92 with the electrical connector 100.

[0157] Optionally, both the in-situ detection element 92 and the signal transmission element 91 extend outward along the male seat body 2, with the extension length of the in-situ detection element 92 being less than the extension length of the signal transmission element 91.

[0158] In this embodiment, after the in-place detection element 92 makes contact with the electrical connection female socket 100 and conducts electricity, the system can determine that the electrical conduction between the signal transmission element 91 and the electrical connection female socket 100 has entered a stable state, and can perform power supply and other execution actions.

[0159] Optionally, the in-situ detection element 92 is located at the center of the male seat body 2. In other cases, the in-situ detection element 92 can also be located at a non-center location of the male seat body 2. The arrangement position of the in-situ detection element 92 can be flexibly adjusted.

[0160] Optionally, the signal transmission element 91 and the in-situ detection element 92 are arranged in an array, which can improve the uniformity of force on the male seat body 2.

[0161] In this application, the guide 8, conductive element 6, signal transmission element 91, and in-situ detection element 92 are all disposed on the same side of the male connector body 2. The extension length of the guide 8 is successively greater than the extension length of the conductive element 6, greater than the extension length of the signal transmission element 91, and greater than the extension length of the in-situ detection element 92. There is a height difference between the guide 8, conductive element 6, signal transmission element 91, and in-situ detection element 92. When assembling the electrical connector assembly, the first-level contact is the contact between the guide 8 and the electrical connector female 100, ensuring the insertion direction of the electrical connector female 100 and the electrical connector male 200, which can play a role in... The first level of contact serves as a guide and limiter; the second level of contact is between the conductive element 6 and the electrical connector 100, ensuring the stability and performance of the conductive element 6 after being limited; the third level of contact is between the signal transmission element 91 and the electrical connector 100, ensuring the effective performance of the signal transmission element 91 after contact; the fourth level of contact is between the in-position detection element 92 and the electrical connector 100, which can be used as the final level of contact. After the in-position detection element 92 is activated, the system can determine that each level of contact of the device carried by the electrical connector assembly has entered a stable state, and power supply and other execution actions can be performed. Conversely, when disassembling the electrical connector assembly, the in-position detection element 92 disengages first, then the signal transmission element 91 disengages, then the conductive element 6 disengages, and finally the guide element 8 disengages. This sequence supports the system to make safe and reliable judgments and actions, maintaining the safety and normal operation sequence of the equipment. Through the multi-level contact design, the electrical connector can achieve various different states and judgment processes of the matching system during assembly or disassembly, which can improve the design safety of the electrical connector assembly and the safety of the system, while also enhancing the functional expandability of the system.

[0162] The male electrical connector in this application, when used in conjunction with the aforementioned female electrical connector, can achieve the same beneficial effects as the aforementioned female electrical connector, which will not be elaborated further here.

[0163] Thirdly, embodiments of this application also disclose an electrical connector assembly, which may include the electrical connection female in the aforementioned first aspect embodiment and the electrical connection male in the aforementioned second aspect embodiment.

[0164] Optionally, the aforementioned electrical connection female and electrical connection male can cooperate with each other to achieve electrical conduction.

[0165] The electrical connector assembly described in this application embodiment has the same beneficial effects as the aforementioned electrical female connector and electrical male connector, and will not be described again in this application embodiment.

[0166] Fourthly, embodiments of this application also disclose an electrical device, which may specifically include the aforementioned electrical connection female socket, or the aforementioned electrical connection male socket, or the aforementioned electrical connector combination.

[0167] Optionally, the electrical equipment may include an aircraft. The aircraft may include, but is not limited to, manned or unmanned aircraft. It may include any one of the following: logistics aircraft, aerial photography aircraft, performance aircraft, industrial operation aircraft, competitive aircraft, and agricultural plant protection aircraft. This application embodiment does not specifically limit the type of aircraft. During flight, the aircraft can perform obstacle detection to find and plan a reasonable flight path in an obstacle-ridden flight environment.

[0168] The electrical equipment described in this application embodiment has the same beneficial effects as the above-mentioned electrical connection female and electrical connection male, and will not be described again in this application embodiment.

[0169] Fifthly, embodiments of this application also disclose a power supply device for electrically connecting to an electrical device. The power supply device includes a circuit board; and an electrical connection terminal, which is detachably mounted on the circuit board and electrically connected to the circuit board. The electrical connection terminal includes one of the aforementioned electrical connection female and electrical connection male, and the electrical device includes the other of the aforementioned electrical connection female and electrical connection male.

[0170] In this embodiment, the power supply device can be used to implement the power supply function and may include a circuit board and electrical connection terminals. The electrical connection terminals are detachably mounted on the circuit board, so that both the circuit board and the electrical connection terminals can be repaired or replaced separately, which helps to reduce the cost of the power supply device.

[0171] In this application, the electrical connection terminals and the circuit board are detachable. When the electrical connection terminals reach the end of their service life, they can be directly replaced, saving time and effort without damaging the circuit board. Therefore, the detachable circuit board and electrical connection terminals enable stable, controllable, and low-cost rapid maintenance of power supply equipment, while greatly reducing the maintenance difficulty, time, and cost of power supply equipment.

[0172] The power supply equipment described in this application embodiment has the same beneficial effects as the above-mentioned electrical connection female and electrical connection male, and will not be described again in this application embodiment.

[0173] Sixthly, embodiments of this application also disclose a spring member that can be applied to an electrical connection female. The spring member may include: multiple spring assemblies that can be enclosed to form a hollow cavity for receiving a conductive element of an electrical connection male that mates with the electrical connection female. The inner surface of the spring assembly has an arc-shaped cross-section in a direction substantially perpendicular to the depth direction of the hollow cavity and protrudes outward toward the center of the hollow cavity, so that when the conductive element is inserted into the hollow cavity along the depth direction of the hollow cavity, the outward protrusion of the inner surface of the spring assembly can contact the conductive element to form electrical conductivity.

[0174] In this embodiment, the inner surface of the spring member has an arc-shaped cross-section in a direction substantially perpendicular to the depth direction of the hollow cavity, and protrudes outward toward the center of the hollow cavity. This allows the protruding portion of the inner surface of the spring assembly to contact the conductive member to form electrical conductivity when the conductive member is inserted into the hollow cavity along the depth direction of the hollow cavity. Furthermore, the protruding portion forms an arc-shaped contact with the conductive member. Even if the protruding portion forming electrical conductivity is relatively offset from the conductive member due to the influence of high-frequency vibration, the protruding portion and the conductive member can still maintain surface contact, avoiding the adverse effects caused by edge contact or point contact, and thus improving the service life of the electrical connector.

[0175] Below, we will take a specific application scenario as an example to introduce the key design points of the electrical connector in this application:

[0176] (1) By adding a limiting design structure to the bottom or top of the cylindrical conductive part 6, a limiting measure is achieved, so that the male and female connectors can achieve zero gap after mating. Due to the use of zero gap design, the connectors in the mating state can achieve a stable following and mating state in all directions of the horizontal plane under the high-frequency vibration of the aircraft. Therefore, the internal flow spring assembly 21 is stably stressed under high-frequency vibration in the horizontal direction, avoiding short-term abnormal impacts in all directions, and effectively improving the overall life of the connectors designed with spring assembly 21. At the same time, this design can also avoid other interference problems in the mating stroke of the male and female connectors. The limiting design is only carried out at the bottom or top position to avoid excessive interference to the mating force. The overall stability of the connectors after mating is achieved by using plastic or metal to achieve near-zero gap mating at the bottom and top of the conductive part 6, thereby effectively improving the life of the connectors.

[0177] This design, by adding plastic or metal limiting elements at the top or bottom of the connector's flow post, achieves stable limiting on the horizontal plane when the male and female connectors are mated, reducing the stress on the internal springs. As a result, the lifespan of the connector is significantly increased, leading to a greater overall improvement in the connector's lifespan.

[0178] (2) The current-carrying performance of the connector is improved by further designing and optimizing the spring assembly 21 of the electrical connection female. This design mainly involves making the spring assembly 21 into a circle and then twisting it at any angle within 90 degrees. The spring assembly 2 is in the form of a torsion spring. More importantly, based on the torsion spring, the inner circular side of each spring assembly 21 is rounded. The angle corresponding to the arc segment is matched according to the torsion angle of the torsion spring. The minimum can be 0 degrees, i.e., a planar contact surface, and the maximum can be 360 ​​degrees, i.e., a single cylindrical spring assembly 21. From the optimal design range, the recommended design range here is 45 to 180 degrees, which can achieve a relatively good design scheme corresponding to the arc segment. This design is not limited to the arc design and can be any other type of arc segment. The design incorporates near-circular elliptical arcs or other curved segments; the single-spring curved design scheme is the optimal design derived through multiple verifications and data tests. It solves the common problem in the design of torsion springs and other spring assemblies 21 where the single spring assembly 21 may rotate or twist during insertion and removal. Because the single spring assembly 21 twists or rotates, its edges and other parts will come into contact with the current-carrying cylinder, which not only reduces the number of contact points and the contact area, but also wears down the surface of the cylindrical conductive part 6, thereby damaging the surface plating and metal layer of the conductive part 6, and further affecting the overall lifespan of the connector. By optimizing the curved design of the single spring of the spring assembly 21, the torsion and wear during use are avoided, effectively improving the product's lifespan.

[0179] This design incorporates an arc-shaped inner edge on the inner side of each spring in spring-type connectors (especially those with torsion angles, such as those with twist angles). This avoids the contact phenomenon between the sharp edges of the spring and the current-passing column after the spring rotates during insertion, removal, and vibration. This ensures that the spring inside the connector can maintain a stable arc-shaped contact effect under various conditions, significantly extending the overall service life of the connector.

[0180] (3) Regarding the design of the cylindrical conductive component 6, since a cylindrical metal component is used at the cylindrical end, this metal component increases the weight of products with high weight requirements, such as aircraft. In order to achieve a balance between the lifespan and weight of the connector and the amount of materials used, the cylindrical metal component is hollowed out, achieving a weight reduction effect without changing the external dimensions and size. The hollow cylindrical metal component achieved by this design invention can achieve the hollow effect through processes such as cold heading or stamping. Through spinning or hot working secondary sealing, a seamless external and internally hollow design structure is achieved, avoiding various problems associated with open structures, such as foreign objects and dirt. The focus of this design invention is to achieve the hollow structure of the metal cylindrical component through a certain process and to couple this hollow structure into the application of high current-carrying connectors. This achieves the matching of different hollow structures without changing the external structure. The hollow structure here can be adjusted to different internal hollow dimensions according to requirements to achieve different weight reduction effects.

[0181] This design, with its hollow cylindrical metal component in the high-current connector, avoids the significant impact of the current-carrying column's weight on the product's weight. By adjusting the thickness of different columns, a balance can be achieved between the current-carrying capacity and weight of the cylindrical current-carrying column, resulting in good weight gains for the product while maintaining a relatively stable current-carrying capacity.

[0182] (4) In related technologies, battery connectors are connected to the battery core board such as the BMS board of the battery through SMT soldering. When the service life of the connector expires, it needs to be replaced. Due to the complex connection between the connector and the battery core board, the replacement operation is difficult and some repair shops cannot perform the operation, resulting in high maintenance difficulty and cost. The embodiments of this application realize quick disassembly and quick repair of the connector and the battery core board by disassembling the connector and the battery core board. This design invention mainly uses the quick-disassembly connection of the connector carrier board and the battery core board to realize the quick-disassembly connection of the signal link and the power link respectively.

[0183] This design, through its quick-release mechanism, significantly reduces the time required to replace the battery connector after its lifespan expires compared to the past when repairing the connector from the core board. It also prevents damage to components such as the battery core board. Therefore, by separating the connector and other critical battery core board components and implementing a separate signal and power link design, stable, controllable, and low-cost rapid repair is achieved, while greatly reducing the difficulty of repair.

[0184] (5) Regarding the multi-level contact sequence of high-current connectors, this application achieves this through a four-layer length difference between the limiting member 7, the conductive member 6, the signal transmission member 91, and the presence detection member 92. The design maintains the following dimensional length relationship: the height of the limiting member 7 > the height of the conductive member 6 > the height of the signal transmission member 91 > the height of the presence detection member 92. By using up to four layers of height differences, the different performance and requirements of the connector during insertion and removal are achieved. During connector insertion, the first layer of contact is the limiting member 7, which ensures the directional restriction of the connector and plays a guiding and multi-level limiting role. The second layer of contact is the conductive member 6, which ensures the stable performance and contact stability of the conductive member 6 after limiting. The third layer of contact is the signal transmission member 91, which ensures the effective performance of the communication PIN after contact. The fourth layer is the presence detection member 92, which serves as the last level of contact PIN. When the presence detection is activated, the system can determine that the various levels of contact of the device carried by the connector have entered a stable state, and power supply and other execution actions can be performed. Conversely, during removal, the in-position detection element 92 disengages first, followed by the signal transmission element 91, then the conductive element 6, and finally the limiting element 7. This sequence allows the system to make safe and reliable judgments and actions, maintaining the safety and normal operation of the equipment. Through this multi-level sequence design, the electrical connector can achieve various states and judgment processes of the matching system under different insertion and removal states, improving the design safety of the connector and the safety of the system.

[0185] This design, through a structural sequence of up to four levels, enables various functions and safety features in different states, ensuring the safety and lifespan of the connector in different usage scenarios, while also enhancing the functional expandability of the device system.
