Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Please refer to Figure 1 and Figure 2 In the first aspect, an electrical connector 100 is provided in an embodiment of the present application. It can be understood that the electrical connector 100 can be one of a male electrical connector and a female electrical connector. When in use, the male electrical connector is arranged on a power output device or a signal output device, and the female electrical connector is arranged on an electrical device or a signal input device. In this way, after the two are connected, the transmission of power or signals is realized.

[0044] The electrical connector 100 includes a housing 10 , an electrical connection component 20 and a magnetic attraction structure 30 .

[0045] The shell 10 is the main bearing structure for installing the electrical connection component 20 and the magnetic attraction structure 30. Here, the outer structure of the shell 10 is not limited. For example, the shell 10 can be a cylindrical shell, a square shell, etc.

[0046] The electrical connection component 20 is a signal or current transmission component in the electrical connector 100. Specifically, the electrical connection component 20 includes an electrical connection terminal 21, one end of which is disposed in the housing 10 and the other end is passed through the housing 10 to the outside. Here, the electrical connection terminal 21 can be a male electrical connection terminal or a female electrical connection terminal. It can be understood that the male electrical connection terminal can be disposed on a power output device or a signal output device, and the female electrical connection terminal can be disposed on an electrical device or a signal input device.

[0047] The magnetic attraction structure 30 is a permanent magnet with magnetism, for example, the magnetic attraction structure 30 can be a permanent magnet made of iron, cobalt, nickel, etc. Alternatively, the magnetic attraction structure 30 can also be an electromagnet with magnetism, for example, the magnetic attraction structure 30 can be a coil supplied with current, or a ring structure, etc.

[0048] The shape of the magnetic structure 30 is not limited and can be adjusted according to actual usage. For example, the magnetic structure 30 can be a cylindrical magnetic structure, a cubic magnetic structure, a layered magnetic structure, and a sheet magnetic structure.

[0049] The magnetic attraction structure 30 is disposed on the housing 10 and / or the electrical connection terminal 21 .

[0050] It can be understood that, according to actual usage requirements, the magnetic attraction structure 30 can be set on the shell 10; or, the magnetic attraction structure 30 can be set on the electrical connection terminal 21; or, the magnetic attraction structure 30 can be set on both the shell 10 and the electrical connection terminal 21.

[0051] For example, the magnetic attraction structure 30 is a columnar permanent magnet, which can be arranged inside the shell 10 and fixed on the inner wall of the shell 10; or, the columnar permanent magnet can also be arranged outside the shell 10 and fixed on the outer wall of the shell 10; or, columnar permanent magnets are arranged on both the inner and outer walls of the shell 10.

[0052] For example, the magnetic attraction structure 30 is a magnetic attraction film layer, and the magnetic attraction film layer is coated on the outer surface of the electrical connection terminal 21 .

[0053] In summary, when the electrical connector 100 is electrically connected and adapted, the magnetic attraction structures 30 on the shell 10 can be magnetically attracted to each other to improve the connection stability of the electrical connection terminals 21 when they are abutted or plugged together; or, the magnetic attraction structures 30 on the electrical connection terminals 21 can be magnetically attracted to each other to improve the connection stability of the electrical connection terminals 21; or, magnetic attraction structures 30 can be provided on both the shell 10 and the electrical connection terminals 21 to further improve the connection stability of the electrical connection terminals 21 after electrical connection.

[0054] The electrical connector 100 provided by the present invention has a magnetic attraction structure 30 disposed on its housing 10 and / or the electrical connection assembly 20 , and utilizes the magnetic attraction effect of the magnetic attraction structure 30 to improve the stability of the electrical connector 100 during the electrical connection process.

[0055] Please refer to Figures 1 to 3 In some embodiments, the housing 10 has a first end plate 11 , the first end plate 11 is used to allow the electrical connection terminal 21 to pass through to the outside, and the magnetic attraction structure 30 is disposed on the first end plate 11 .

[0056] It can be understood that the first end plate 11 is the part of the shell 10 that will directly dock and contact when the two electrical connectors 100 are electrically connected, that is, when the male electrical connector and the female electrical connector are docked, the first end plates 11 of the two electrical connectors 100 will directly abut and contact so that the electrical connection terminals 21 are electrically connected. This is also the reason why the electrical connection terminals 21 need to pass through the first end plate 11 and extend to the outside.

[0057] Thus, by disposing the magnetic attraction structure 30 on the first end plate 11 , the magnetic attraction distance can be further shortened, thereby increasing the magnetic attraction force between the two electrical connectors 100 , that is, the connection stability between the two can be further improved.

[0058] Of course, the shell 10 also has other end plates. The first end plate 11 and the other end plates are combined to form a hollow structure with an accommodating cavity to meet the accommodation and installation requirements of the electrical connection component 20 and other components.

[0059] Please refer to Figures 3 to 5 In some embodiments, the first end plate 11 has an outer surface 11a and an inner surface 11b disposed opposite to the outer surface 11a, and the magnetic attraction structure 30 is disposed on the outer surface 11a and / or the inner surface 11b.

[0060] It can be understood that the outer surface 11 a is the outward surface of the first end plate 11 , ie, the surface in contact when the two electrical connectors 100 are connected, and the inner surface 11 b is the surface opposite to the outer surface 11 a and located inside the housing 10 .

[0061] According to actual usage requirements, the magnetic structure 30 can be set on the outer surface 11a of the first end plate 11; or, it can also be set on the inner surface 11b of the first end plate 11; or, the magnetic structure 30 can also be set on both the outer surface 11a and the inner surface 11b of the first end plate 11.

[0062] It should be noted that the connection method between the magnetic attraction structure 30 and the outer surface 11a and / or the inner surface 11b includes but is not limited to plug-in connection, clip-on connection, adhesive connection, and threaded connection.

[0063] For example, a retaining structure may be formed by protruding on the inner surface 11b of the first end plate 11, and the magnetic attraction structure 30 may be disposed in the retaining structure, or a mounting groove may be opened on the inner surface 11b of the first end plate 11 to dispose the magnetic attraction structure 30 in the mounting groove. Similarly, a retaining structure or a mounting groove may be provided on the outer surface of the first end plate 11 to fix the magnetic attraction structure 30.

[0064] In this way, the magnetic connection strength of the magnetic structure 30 can be further improved, so as to improve the connection stability of the electrical connector 100 during connection.

[0065] Please refer to Figure 5 In some embodiments, a through hole 11c penetrating the outer surface 11a and the inner surface 11b is formed on the first end plate 11, and the magnetic attraction structure 30 is disposed in the through hole 11c.

[0066] It can be understood that the through hole 11c is a hole structure that penetrates the first end plate 11 so that the inside and outside of the housing 10 are connected. The hole structure of the through hole 11c includes but is not limited to a straight hole, a stepped hole, an inclined hole, etc., and the hole shape of the through hole 11c includes but is not limited to a circular through hole 11c, a square through hole 11c, an elliptical through hole 11c, etc.

[0067] In this way, the magnetic attraction structure 30 can be fixed through the through hole 11c, and at the same time, the magnetic attraction distance can be further shortened to enhance the mutual magnetic attraction force.

[0068] Optionally, the magnetic attraction structure 30 is placed in the through hole 11c, and the magnetic end face of the magnetic attraction structure 30 is flush with the outer surface 11a. In this way, when the two electrical connectors 100 are abutted and connected, the corresponding magnetic attraction structures 30 can directly contact and magnetically attract each other to improve the stability of the two electrical connectors 100 when they are connected.

[0069] Please refer to Figure 1 and Fig. 9 In some embodiments, the outer contour of the first end plate 11 is circular, elliptical, gourd-shaped or racetrack-shaped.

[0070] It can be understood that the outer contour of the first end plate 11 refers to the outer contour formed by the projection of the first end plate 11 in the projection direction perpendicular to the outer surface 11 a.

[0071] Thus, setting the outer contour of the first end plate 11 to be circular, elliptical, gourd-shaped or racetrack-shaped can effectively reduce the contact area of ​​the housing 10 of the electrical connector 100 during electrical connection, and is also conducive to the design of the housing 10 towards miniaturization.

[0072] Alternatively, if Fig. 9As shown, the shell 10 is a cylindrical structure, and the outer contour of the first end plate 11 is circular, so the outer diameter of the shell 10 is consistent, which makes the overall volume of the shell 10 smaller.

[0073] Alternatively, if Figure 1 As shown, the shell 10 is a columnar structure, and the outer contour of the first end plate 11 is a racetrack shape. Similarly, the outer diameter of the shell 10 is consistent, which makes the overall volume of the shell 10 smaller.

[0074] Of course, in other embodiments, the shell 10 may also be a columnar structure, but the outer diameter of the shell 10 may be adjusted. For example, in the plug-in assembly direction away from the electrical connector 100, the outer diameter of the shell 10 gradually increases starting from the first end plate 11. In this way, the shell 10 as a whole presents a "big at one end and small at the other end" structure.

[0075] Please refer to the figure. In some embodiments, a positioning structure 11 d is formed on the outer surface 11 a . The positioning structure 11 d surrounds the electrical connection terminal 21 .

[0076] It can be understood that the positioning structure 11 d is a structure formed on the outer surface 11 a and is used to perform a corresponding positioning function for the electrical connection terminal 21 when docking.

[0077] The positioning structure 11d includes, but is not limited to, a groove, a protrusion, and a combination of a groove and a protrusion formed on the outer surface 11a.

[0078] The positioning structure 11d should surround the outer circumference of the electrical connection terminal 21 to play a corresponding positioning role for the electrical connection terminal 21 to be connected, and can also limit the short circuit caused by the electrical connection terminal 21 being misaligned.

[0079] For example, Fig. 9 As shown, the positioning structure 11d formed on the outer surface 11a is an annular convex rib surrounding the outer circumference of the electrical connection terminal 21, and forms a docking and fitting relationship with the corresponding groove of the housing of the electrical connector.

[0080] Please refer to Figures 6 to 8 In some embodiments, the magnetic attraction structure 30 is disposed on the electrical connection terminal 21; and / or

[0081] The magnetic attraction structure 30 is disposed in the electrical connection terminal 21 .

[0082] It is understandable that when two electrical connectors 100 are docked, or when the current electrical connector 100 is docked with another connector, it is the electrical connection terminals 21 thereof that are docked to achieve power or signal transmission.

[0083] Here, the electrical connection terminal 21 may be a male electrical connection terminal or a female electrical connection terminal.

[0084] At the same time, the magnetic attraction structure 30 is arranged on the electrical connection end as follows: the magnetic attraction structure 30 can be arranged on the outer surface 11a of the electrical connection terminal 21; or, the magnetic attraction structure 30 can also be arranged inside the electrical connection terminal 21; or, the magnetic attraction structure 30 can also be arranged inside the electrical connection terminal 21, and part of it extends to the outer surface 11a of the electrical connection terminal 21, or extends to the outside of the electrical connection terminal 21.

[0085] For example, the magnetic attraction structure 30 is a magnetic coating applied to the outer surface 11a of the electrical connection terminal 21, and, according to actual use requirements, the magnetic coating can coat the entire outer surface 11a or a portion of the outer surface 11a of the electrical connection terminal 21. At the same time, the magnetic coating is also conductive, and also meets the requirement that the corresponding electrical connection terminal 21 needs to be conductive when plugged in.

[0086] For example, the magnetic attraction structure 30 is a permanent magnet block, which is disposed in the electrical connection terminal 21 so as to provide a corresponding magnetic attraction force when the electrical terminals are connected.

[0087] Specifically, please refer to Figures 6 to 8 , the magnetic attraction structure 30 includes a magnetic layer 31 coated on the outside of the electrical connection terminal 21; or,

[0088] The magnetic attraction structure 30 includes a magnetic body 32 disposed in the electrical connection terminal 21 .

[0089] It can be understood that the magnetic layer 31 is a relatively thin magnetic attraction structure 30. For example, the magnetic layer 31 can be a coating or a sputtered layer having a magnetic material, or the magnetic layer 31 can also be a relatively thin magnetic sheet.

[0090] Furthermore, the magnetic body 32 is a block-shaped permanent magnet with a certain volume.

[0091] For example, the magnetic layer 31 can be formed on the entire outer wall or a part of the outer wall of the electrical connection terminal 21 by spraying, sputtering, electroplating, etc.

[0092] For another example, the magnetic body 32 can be manufactured simultaneously with the electrical connection terminal 21 through an integral molding method, or after the electrical connection terminal 21 is manufactured, the magnetic body 32 can be fixed in the electrical connection terminal 21 by forming a mounting hole and other structures through milling or other methods.

[0093] Please refer to Figure 8 In some embodiments, the electrical connection terminal 21 has a plug-in end surface 21 a , and the plug-in end surface 21 a is coated with a magnetic layer 31 ; and / or

[0094] The magnetic body 32 is disposed inside the electrical connection terminal 21 and close to the plug-in end surface 21 a .

[0095] It can be understood that the plug-in end surface 21a is the end surface that the electrical connection terminal 21 directly contacts when connected. The plug-in end can be a flat surface, an arc surface, or a corrugated surface, etc., or the plug-in end surface 21a can also be composed of multiple sub-surfaces.

[0096] In this way, the magnetic layer 31 is formed on the plug-in end surface 21 a, which is more conducive to providing connection stability when the two electrical connection terminals 21 are connected.

[0097] Alternatively, the magnetic body 32 may be disposed close to the plug-in end surface 21 a to provide a corresponding magnetic force.

[0098] In some embodiments, the housing 10 has a second end plate (not shown) disposed opposite to the first end plate 11 , and an indicator light (not shown) is disposed on the second end plate, and the indicator light is electrically connected to the electrical connection terminal 21 .

[0099] It can be understood that the second end plate is a plate structure opposite to the first end plate 11 , that is, the second end plate should be a plate structure facing outward or toward the user after the electrical connector 100 is connected.

[0100] In this way, an indicator light is set on the second end plate to provide a prompt indication after the electrical connection terminal 21 is docked. At the same time, the indicator light is installed on the current electrical connector 100, which can effectively reduce the volume of the electrical connector that is docked with the current electrical connector 100, and reduce the difficulty of installing the indicator light in the space of the docked electrical connector.

[0101] Please refer to Figure 2 In some embodiments, the electrical connection component 20 also includes a control board group 22 disposed in the shell 10, the control board group 22 includes a substrate 221 and a support plate 222 arranged at intervals along the height direction of the shell 10, the substrate 221 is electrically connected to the support plate 222, and one end of the electrical connection terminal 21 is disposed on the support plate 222 and is electrically connected to the support plate 222.

[0102] It can be understood that the direction indicated by the arrow in the figure is the height direction of the housing 10. The substrate 221 is a main control board for processing corresponding electrical signals, and the support plate 222 is used to carry and fix the electrical connection terminal 21. The substrate 221 and the support plate 222 can form a spaced position relationship through support columns such as columns, or can form a spaced position relationship by being adapted and connected to the inner wall of the housing 10.

[0103] Optionally, in the height direction of the shell 10, the projection of the support plate 222 falls within the projection of the substrate 221, that is, the size of the support plate 222 is less than or equal to the size of the substrate 221. In this way, the cross-sectional area of ​​the shell 10 in the direction perpendicular to the height can be smaller, and then the ratio of the square of the height of the shell 10 to the cross-sectional area is larger, and the overall structure of the shell 10 presents a "long and thin" structural feature.

[0104] In this way, compared with the electrical connector 100 using a single control board, stacking the substrate 221 and the support plate 222 can further reduce the cross-sectional area of ​​the shell 10, which is more conducive to the shell 10 presenting a "long and thin" structural feature, thereby enabling this type of electrical connector 100 to adapt to some usage scenarios with a smaller docking contact area.

[0105] For example, Figure 2 As shown, in the height direction of the shell 10, the projections of the base plate 221 and the support plate 222 are both runway-shaped, and the cross-sectional shape of the shell 10 is adapted to the base plate 221 and the support plate 222, and is also runway-shaped. In this way, the overall shape of the shell 10 presents a tall and thin structural feature.

[0106] For example, in the height direction of the shell 10, the projections of the substrate 221 and the support plate 222 are both circular, and the cross-sectional shape of the shell 10 is adapted to the substrate 221 and the support plate 222 and is also circular. In this way, the overall shape of the shell 10 presents a long and slender structural feature.

[0107] Please refer to Fig.10 In a second aspect, an embodiment of the present application further provides a charging device, comprising the above-mentioned electrical connector 100.

[0108] It is understandable that the charging device should also have a charging connector 200 etc. for connecting to a power source or an adapter.

[0109] The charging device provided by the utility model, based on the electrical connector 100, has a higher safety factor during use.

[0110] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
