DETAILED DESCRIPTION

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example 1

[0042] Reference Figures 1-13 As shown, a female connector of the present invention is used to connect to a male connector to be plugged in, comprising:

[0043] A first insulating base 1 is provided with a plurality of first accommodating cavities 18 , and the plurality of first accommodating cavities 18 all penetrate the first insulating base 1 ;

[0044] The socket assembly is provided in at least two spaced-apart groups and includes: a first sleeve 12 accommodated in the first accommodating cavity 18; a current-passing terminal 13 coaxially disposed within the first sleeve 12; the current-passing terminal 13 includes: a coaxially disposed first ring 131 and a second ring 132; and a plurality of arms 134 connected at both ends to the first ring 131 and the second ring 132, respectively. The plurality of arms are parallel to each other and arranged axially inclined relative to the current-passing terminal 13, and the arms 134 gradually radially approach the sleeve axis in a direction extending away from the first ring 131 and the second ring 132.

[0045] The cover body 11 is covered on the first sleeve body 12 , and the first ring 131 is pressed between the first sleeve body 12 and the cover body 11 .

[0046] The present invention relates to a female connector. When the male connector to be plugged in is connected to the female connector, the signal component is used to transmit the current signal. The power terminal 10 of the male connector is plugged into the current-carrying terminal 13 of the socket component. Due to the conductivity of the first sleeve 12, the current is conducted to the current-carrying terminal 13 and the first sleeve 12 through the first sleeve 12. The arm 134 is radially inclined so that the contact point between the arm 134 and the male terminal is squeezed by the male terminal and expanded radially outward. The arm 134 on both sides of the contact point can fit into the male terminal, so that the contact point is expanded to form a conductive contact surface, and the initial contact The elastic abutment force of the contacts is large, and they can maintain a tight connection during vibration to form a stable passage. The arm body 134 is tilted axially along the current-carrying terminal 13, so that the length of the arm body 134 between the first ring 131 and the second ring 132 is increased, and the elastic expansion and contraction space of the arm body 134 is increased in the small-sized current-carrying terminal 13. Through the set cover body 11, the current-carrying terminal 13 is fixedly crimped in the sleeve body. At the same time, the sleeve body guides the male terminal insertion and prevents the current-carrying terminal 13 from being axially squeezed. It has the advantages of shock resistance, wear resistance, and anti-micro-wear, which not only improves the service life, but also can transmit a large current of 500A for a long time.

[0047] By designing the connector's through-current terminal 13 structure, laying out a double-row through-current structure, and coordinating it with the mating port, a technology that achieves fast charging with a maximum power current of 9650W and provides stable power supply during operation is achieved, thus ensuring the power supply of the plant protection drone.

[0048] The female connector also features a signal assembly, comprising multiple female terminals 4 positioned between adjacent socket assemblies. When current is transmitted through the through-current terminals 13, the female terminals 4 positioned between adjacent socket assemblies come into contact with corresponding signal contacts on the male connector. This contact between the female terminals 4 and the signal contacts enables signal transmission, enabling the female connector to simultaneously transmit current and signals.

[0049] The first insulating substrate 1 is used to isolate the various socket components and signal components, and provide a housing and support base to prevent interference between current and signals. The insulating performance of the first insulating substrate 1 can effectively avoid leakage and short circuit.

[0050] Reference Figure 8 As shown, the first sleeve 12 has a second accommodating cavity 19, and the second accommodating cavity 19 is used to plug in the male end connector. The first end of the first accommodating cavity 18 is provided with a socket, and the socket is connected to the second accommodating cavity 19. The cover body 11 is provided at the socket, and the sleeve is accommodated in the first accommodating cavity 18, and the second accommodating cavity 19 is formed inside it. The cover body 11 is provided at the top of the second accommodating cavity 19.

[0051] Continue to refer to Figure 8 As shown, the cover body 11 includes a first connecting portion 111 and a second connecting portion 112, the first ring 131 is crimped between the first connecting portion 111 and the first sleeve 12, the second connecting portion 112 is arranged at the first end of the first sleeve 12, the inner circle of the second connecting portion 112 is provided with a first inclined portion 114, and an arc surface is provided between the first inclined portion 114 and the first connecting portion 111, the cover body 11 is arranged at the socket to cover and protect the socket, the first connecting portion 111 and the sleeve are coaxially arranged, and the inner circle thereof can fit the outer peripheral side of the male terminal, the outer circle is crimped to the inner side of the first ring 131, the second connecting portion 112 is connected to the upper end of the first connecting portion 111, the top of the first sleeve 12 is slightly lower than the socket, the second connecting portion 112 is horizontally arranged on the top of the first sleeve 12 and the first ring 131, so that the cover body 11 is completely accommodated in the first accommodating cavity 18, and the second connection is respectively abutted against the male end connection and the top of the first sleeve 12 on the upper and lower sides.

[0052] The conductor material terminals required for fast charging are made of copper alloy with higher conductivity. Copper conductors + high-conductivity copper arms 134 are used to pass higher currents in fixed conductors, thereby improving the product's current-carrying capacity and extending its seismic service life. The contact structure and contact shape of the current-carrying terminal 13 are redesigned and optimized. By setting the shape of the inclined arm 134, the contact area is increased, and the contact fit between the two ends and the main body is optimized, the current-carrying area of the entire current-carrying circuit is maximized to meet the 500A current-carrying capacity. The arm 134 is made of a secondary-quaternary first ring 131 and a second ring 132 reverse differential rotation process.

[0053] The outer peripheral side of the cover body 11 is also provided with an annular groove 113. The top of the cover body 11 can be slightly higher than the height of the peripheral side of the socket, and the height of the first ring 131 is slightly higher than the height of the sleeve, so that when the male connector is docked, the arm body 134 is pressed down close to the male terminal to obtain more contact conductive surface.

[0054] Reference Figure 8As shown, the first sleeve 12 is provided with a first abutting portion 121 and a second abutting portion 122 in sequence toward its second end, and the second ring 132 abuts against the end face of the first abutting portion 121. The inner diameter of the first abutting portion 121 is larger than the second abutting portion 122. When assembling the female connector, the through-current terminal 13 is placed into the first sleeve 12, and the second ring 132 of the through-current terminal 13 will contact the end face of the second abutting portion 122 and abut against the step surface there. Since the inner diameter of the first abutting portion 121 is larger than the second abutting portion 122, when the through-current terminal 13 is placed, the second ring 132 can pass through the position of the first abutting portion 121 more smoothly until it abuts against the end face of the second abutting portion 122, and the male terminal of the male connector abuts against the bottom surface of the second connecting portion 112.

[0055] Reference Figure 6 As shown, the number of the arm bodies 134 is not less than two, and the axial inclination angle of the arm body 134 is 0°-90°. The projection angle is the angle between the arm body projected onto the circumferential surface where the first ring and the second ring are located, and the axis of the circumferential surface. In this embodiment, the inclination angle of the arm body 134 is variable. The part of the arm body 134 close to the first ring 131 and the second ring 132 is a third inclined portion 1341, and its inclination angle is 20°-30°. Between the two third inclined portions 1341 is a fourth inclined portion 1342, and its inclination angle is 35°-45°. The inclination angle of the third inclined portion 1341 is smaller and is arc-shaped, and the inclination angle of the fourth inclined portion 1342 is larger. The inclination angle is the angle between each inclined portion and the vertical direction. The third inclined portion 1341 is more The arm bodies 134 are arranged flat and smooth, with rounded corners 133 provided between adjacent arms 134. The rounded corners 133 are provided between the first ring 131 and the second ring 132. The number of arms 134 is no less than two, which increases the number of contact points with the male terminal and improves the stability and reliability of current transmission. In some embodiments, the number of arms 134 can be three, four, five, six, ten, twenty, thirty, thirty-five, or more. In this embodiment, thirty-five are preferred. They are evenly distributed between the first ring 131 and the second ring 132. The rounded corners 133 can alleviate stress concentration between adjacent arms 134, allowing the stress on the arms 134 to be more evenly distributed when subjected to external forces, thereby improving the overall structural strength and reliability of the current-carrying terminal 13. In addition, the rounded corners 133 can also make the deformation of the arms 134 smoother and more uniform when the male connector is plugged in, further improving contact stability and conduction, and removing burrs during processing to slow wear.

[0056] Reference Figure 1-Figure 4 As shown, the four power terminals 10 of the socket assembly are arranged in a matrix, and the male terminal 8 and the female terminal 4 of the signal terminal are arranged between the power terminals 10 and are arranged at a distance and accommodated in the corresponding stretching body 102.

[0057] Reference Figure 1-Figure 3 As shown, the first insulating base 1 is provided with a plurality of fourth accommodating cavities 5 extending therethrough, and the female terminals 4 are embedded in the fourth accommodating cavities 5. The female terminals 4 are used to connect to the signal terminals of the male connector. The first insulating base 1 is also provided with a third accommodating cavity 15, which is provided on both sides of the socket assembly. A second sleeve 17 is embedded in the third accommodating cavity 15. When the male connector and the female connector are plugged in, the signal terminals of the male connector contact the female terminals 4, thereby achieving signal transmission. The plurality of fourth accommodating cavities 5 of the first insulating base 1 provide fixed positions for the female terminals 4, enabling the female terminals 4 to connect to the signal terminals of the male connector. A second curved surface 21 is provided at the opening of the second sleeve 17.

[0058] In this solution, the second housing 17 is made of any one of stainless steel, copper alloy, titanium alloy and Teflon. In this embodiment, Teflon, i.e. polytetrafluoroethylene, is preferred because it is wear-resistant and prevents friction damage.

[0059] Reference Figure 1-Figure 2 As shown, the first insulating base 1 includes: a platform body 101 and multiple stretching bodies 102. The openings of the first sleeve 12 and the second sleeve 17 of the platform body 101 are both set on the side of the platform body 101 facing the male connector. The stretching bodies 102 extend to the other side of the platform body 101 respectively. The stretching bodies 102 are used to accommodate the first sleeve 12 and the second sleeve 17. When the male connector is plugged into the female connector, the terminals of the male connector are plugged into the corresponding components of the female connector through the openings on the platform body 101. The platform body 101 provides a unified contact surface for the openings of the first sleeve 12 and the second sleeve 17, so that the male connector can be more accurately docked with the female connector. The stretching body 102 provides a stable accommodation space for the first sleeve 12 and the second sleeve 17, so that they will not be displaced or loosened during use, and can effectively integrate and isolate the various components to prevent interference between different components, while ensuring the normal operation of the connector and the stability of signal transmission. Example 2

[0060] Reference Figures 1-11 As shown, this embodiment discloses a male end connector, which includes: a second insulating base 6, a power terminal 10, and a male terminal 8;

[0062] The male terminal 8 is used to electrically contact the female terminal 4 to transmit signals.

[0063] This embodiment discloses a male connector with a second insulating base 6 serving as the supporting and insulating portion of the entire male connector. One end of a power terminal 10 is disposed within the second insulating base 6, and the other end of the power terminal 10 is inserted into the current-carrying terminal 13 of the female connector, thereby connecting with the female connector and achieving the purpose of current transmission. The male terminal 8 is used to electrically contact the female terminal 4 of the female connector to achieve signal transmission. When the male and female connectors are plugged together, the male terminal 8 and female terminal 4 contact each other, allowing signal transmission between the two.

[0064] Reference Figures 9-11 As shown, the second insulating base 6 includes: a base portion and a raised portion 20, the raised portion 20 extends on one side of the base portion and forms a step surface with the base portion, and the base portion is provided with a drainage groove (not shown in the figure), which is used to increase the drainage capacity. The drainage groove is provided on both sides of the communication male terminal 8 and also on the inner or outer side of the power terminal. When docking, the accumulated water can be discharged smoothly to the outside to prevent the contact area water from causing short circuit, rust, poor contact and other problems in the connector. The power terminal 10 is provided on the raised portion 20, and guide posts 22 for plugging into the second sleeve 17 are also provided on both sides of the power terminal 10. The end of the guide post 22 is a tapered portion, and the male connector is guided and positioned by the guide post 22 to achieve quick plug-in guide performance to ensure that the mating is not offset. After more than 5,000 plug-in and unplug cycles, the guide post spacing size achieves a tolerance specification within 0.06 mm to ensure stable contact of the mating port and avoid offset during flight vibration, which causes current power attenuation.

[0065] The female terminal 4 and the male terminal 8 are a matrix-shaped metal terminal structure. By integrating sensors and communication modules, they can realize functions such as current monitoring, battery status monitoring and remote control, thereby improving the safety and intelligence level of the drone.

[0066] Continue to refer to Figures 9-11 As shown, the guide column 22 and the power terminal 10 are hollow structures. The power supply metal parts are designed to be lightweight, and the vacuum hollow structure process technology with metal heating and sealing is adopted. While reducing their own weight, the load-bearing weight and battery life can be increased without increasing the male socket voltage. The power terminal 10 can also be a solid structure to increase the current carrying capacity, and the guide column 22 can also be a solid structure to increase the structural strength.

[0067] The power terminal 10 is arranged on the raised portion 20, and a first curved surface 16 is provided at the end of the power terminal 10. When the male connector is connected to the female connector, a gap is formed between the platform body 101 of the female connector and the male connector, providing a space 7 for the connector to be disengaged and removed, such as when a hand or a manipulator reaches into the gap. In addition, a support portion 2 is provided on the peripheral side of the stretching body 102 to facilitate abutment by a hand or a manipulator, so that the support portion 2 provides an abutment and disengagement position at the female connector, and the male connector provides a removal and disengagement position at the gap. The first insulating base 1 and the second insulating base 6 are also respectively provided with a locking portion 3, and a threaded sleeve or a screw is embedded in the locking portion 3, which is used to connect to the battery pack or the drone, respectively.

The positioning through hole has a first ring 92, a transition portion 93, a second ring 94 and a vertical portion 95 that are coaxial and fixed around the power terminal 10. The outer diameter of the second ring 94 gradually decreases on the side away from the first ring 92, and the outer diameter of the second ring 94 is not larger than that of the first ring 92. The two ends of the transition portion 93 are respectively connected to the first ring 92 and the second ring 94. The end surface of the vertical portion 95 is inclined inwardly and increased to form a guide surface 96. The bottom of the first ring 92 is also provided with a second inclined portion 91. The first inclined portion 114 and the first ring 92 are respectively interference fit to be accommodated in the second ring 92. In the inner cavity enclosed by the second inclined portion 91 and the first connecting portion 111, the first ring 92, the transition portion 93, the second ring 94 and the vertical portion 95 constitute the plug-in positioning assembly 9, and the second inclined portion 91, the first ring 92, the transition portion 93, the second ring 94 and the vertical portion 95 extend from the male connector to the female connector in sequence, and the outer diameters of the second inclined portion 91, the first ring 92, the transition portion 93, the second ring 94 and the vertical portion 95 gradually decrease, wherein the second inclined portion 91 is conical, the first ring 92 is a straight sleeve and the outer diameter is the same as the uppermost part of the first inclined portion 114, the transition portion 93 narrows in an arc shape upward, the second ring 94 narrows in a taper upward, the vertical portion 95 is a straight sleeve and the outer diameter is the same as the uppermost part of the second ring 94.

[0069] The plug-in positioning component 9 and the second insulating base 6 have a coaxial inner cavity, and the second insulating base 6 is provided with a card slot 14, which is used to be connected with the power terminal 10. The above-mentioned male and female interference fit design reduces the wear of the connector contact area caused by high vibration micro-wear of the drone, and solves the risk of overheating and burning of the current terminal 13 caused by oxides accumulated in the contact area due to wear.

[0070] The conductive parts of the first insulating base and / or the second insulating base are placed by embedded injection molding. The conductive parts are any one or more of the cover body, power terminal, male terminal, female terminal, first sleeve body, and second sleeve body. Embedded injection molding is also called insert molding. The conductive parts are pre-fixed at the corresponding position in the injection mold of the first insulating base and / or the second insulating base, and then injected into the plastic for molding. After the mold is opened, the conductive parts are tightly wrapped by the cooled and solidified plastic and buried in the plastic; in addition, the sleeve locking parts on the first insulating base and the second insulating base are also placed therein by embedded injection molding. The sleeve locking parts are plug-in locking parts with holes or internal thread locking parts. Example 3

[0071] Reference Figure 1-Figure 2 As shown, this embodiment also discloses a shock-resistant, wear-resistant, high-current connector assembly, including the male connector described in Example 1 and the female connector described in Example 2.

[0072] In this embodiment, the connector assembly comprises an arm having a spiral structure, and the middle portion of the arm is positioned close to the central axis of the current-carrying terminal, forming a plug-in space similar to a hyperbolic structure. This increases the elastic floating ability of the arm relative to the power terminal, thereby enhancing the resistance to fretting wear in a vibration environment. The male connector is plugged into the female connector, and the power terminal 10 of the male connector is inserted into the current-carrying terminal 13 of the female connector, forming a stable connection structure, improving the product's current-carrying capacity, and extending the product's service life in a vibration-resistant environment.

[0073] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this utility model.
