DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, these directional terms are intended to illustrate and facilitate understanding of this disclosure and are not intended to limit this disclosure. Furthermore, in the accompanying drawings, similar or identical structures are denoted by the same reference numerals.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0057] The embodiment of the utility model solves the problem that the existing charging coupler is easy to loosen when plugged in for charging by providing a charging coupler, a socket and a plug thereof, and an ultrasonic system. By providing a first magnetic reflector and a second magnetic reflector to reflect magnetic lines of force and enhance magnetic attraction, the reliability of the connection between the plug and the socket is improved.

[0058] The embodiment of the present utility model is to solve the problem of looseness of the plug and the socket, and its technical solution is as follows:

[0059] For the socket, a first magnetic reflector is provided behind the first magnetic part of the socket. The first magnetic reflector can reflect the magnetic lines of force of the first magnetic part to the first plug-in end face for plugging, thereby enhancing the magnetic attraction of the first magnetic part. For the plug, a second magnetic reflector is provided behind the second magnetic part of the plug. The second magnetic reflector can reflect the magnetic lines of force of the second magnetic part to the second plug-in end face for plugging, thereby enhancing the magnetic attraction of the second magnetic part. The first magnetic part and the second magnetic part have opposite magnetic properties and are used to magnetically attract each other when the plug and the socket are combined. In this way, based on the principle that the first magnetic reflector and the second magnetic reflector reflect the magnetic lines of force to enhance the magnetic attraction, when the plug and the socket are plugged in, under the action of the enhanced magnetic attraction, the plug and the socket are combined more firmly and firmly, not easy to loosen, and the reliability is improved.

[0060] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0061] Reference Figure 1- Figure 4. An embodiment of the present invention provides a charging coupler socket 100, comprising: a female socket 110, a first electrical connector 120, and a first magnetic member 130. The female socket 110 has a first plugging end surface 111; the first electrical connector 120 is disposed in the female socket 110 and exposed at the first plugging end surface 111; the first magnetic member 130 is disposed in the female socket 110 and adjacent to the first electrical connector 120, the first magnetic member 130 having a first magnetic pole portion 131 and a second magnetic pole portion 132, the first magnetic pole portion 131 and the second magnetic pole portion 132 having opposite polarities, and the first magnetic pole portion 131 and the second magnetic pole portion 132 being arranged in a direction parallel to the first plugging end surface 111; and a first magnetic reflector 140 is disposed on a side of the first magnetic member 130 facing away from the first plugging end surface 111.

[0062] Specifically, the female socket 110 is used to be installed on the housing of the ultrasound device 300, which can be a portable ultrasound device 300. The female socket 110 can be in the shape of a rectangular shell. The size of the rectangular shell is adapted to the installation space on the housing of the ultrasound device 300, and is specifically set according to actual needs. The front side of the rectangular shell is the first plug-in end face 111 of the female socket 110. The front side of the rectangular shell is provided with a circle of limiting enclosure 112. The limiting enclosure 112 is provided around the first plug-in end face 111. The limiting enclosure 112 is used to limit the inserted plug to prevent the plug from loosening, ensure the reliability of the connection, and prevent accidental pulling that causes the female socket 110 and the male connector 210 to separate and cause medical accidents. The back side of the rectangular shell faces the interior of the outer shell. The first electrical connector 120 is a pin, also known as a pin needle. The pin is inserted into the rectangular shell in a direction perpendicular to the first plug-in end face 111. The pin is exposed at the first plug-in end face 111. One end of the pin is used to mate with the plug, and the other end of the pin is inserted into the back side of the rectangular shell. The other end of the pin is used to electrically connect to the circuit board in the outer shell. It should be noted that the pin is exposed at the first plug-in end face 111, which means that the pin is not completely enclosed in the female socket 110. The pin can be higher than the first plug-in end face 111, or lower than or flush with it, as long as it can be exposed on the female socket 110 and connected in place with the second electrical connector 220. The first magnetic member 130 can be a magnet. The first magnetic member 130 is arranged inside the female socket 110, close to the first plug-in end face 111, and the first magnetic member 130 is adjacent to the first electrical connector 120 in the female socket 110, so that the first magnetic member 130 can generate a magnetic field around the first electrical connector 120. Specifically, the first magnetic member 130 has two magnetic pole portions with opposite polarities, namely the first magnetic pole portion 131 and the second magnetic pole portion 132. The first magnetic pole portion 131 is, for example, the N pole, and the second magnetic pole portion 132 is the S pole, or the first magnetic pole portion 131 is the S pole, and the second magnetic pole portion 132 is the N pole. The first magnetic member 130 is parallel to the first plug-in end face 111 as a whole, and the first magnetic pole portion 131 and the second magnetic pole portion 132 are distributed along the direction parallel to the first plug-in end face 111, that is, the first magnetic pole portion 131 and the second magnetic pole portion 132 are arranged horizontally relative to the first plug-in end face 111, rather than vertically. Therefore, two magnetic attraction positions with opposite polarities can be generated on the first plug-in end face 111 through a first magnetic member 130. One magnetic attraction position is an N-pole magnetic attraction position, which can attract magnetic objects with an S pole and repel magnetic objects with an N pole, and the other magnetic attraction position is an S-pole magnetic attraction position, which can attract magnetic objects with an N pole and repel magnetic objects with an S pole. The charging coupler plug 200 is provided with a second magnetic member 230. Only when the charging coupler plug 200 is correctly inserted, the first magnetic pole portion 131 and the second magnetic pole portion 132 will be magnetically attracted to the second magnetic member 230, guiding the second electrical connector 220 on the charging coupler plug 200 to dock with the first electrical connector 120.When the charging coupler plug 200 is inserted upside down, that is, when it is reversed 180° and inserted, the first magnetic pole portion 131 and the second magnetic pole portion 132 magnetically repel the second magnetic part 230, preventing the plug from being inserted, thereby preventing fooling around. Since the female socket 110 is limited by the installation space of the outer shell of the ultrasonic equipment 300, the volume of the female socket 110 is often designed to be smaller, and the internal space of the female socket 110 is also smaller. The volume of the first magnetic part 130 is also correspondingly limited by the internal space of the female socket 110, so its magnetic field strength is often not large, and the magnetic attraction force generated is insufficient. In order to enhance the magnetic attraction force of the first magnetic part 130, this embodiment provides a first magnetic reflector 140 on the side of the first magnetic part 130 that is away from the first plug-in end face 111, that is, on the back side of the first magnetic part 130. Among them, the first magnetic reflector 140 can be fixed to the back side of the first magnetic part 130 by welding, bonding, adsorption or fixing. The magnetic reflection member shields the leakage magnetic flux of the first magnetic member 130 to the back side, prevents the magnetic lines of force from leaking to the back side, and reflects the magnetic lines of force onto the first plug end face 111, thereby enhancing the magnetic attraction of the first magnetic member 130, making the first magnetic member 130 more firmly combined with the second magnetic member 230 of the charging coupler plug 200, thereby improving reliability.

[0063] Through this embodiment, a first magnetic member 130 is provided in the female seat 110, and the magnetic attraction force generated when the first magnetic pole portion 131 and the second magnetic pole portion 132 of the first magnetic member 130 are correctly aligned with the second magnetic member 230 of the plug is used to guide the insertion, thereby achieving convenient and accurate plug-in and pull-out operations, and the connection is effective and reliable, which can prevent the socket and the plug from being separated by accidental pulling and causing medical accidents; at the same time, the magnetic repulsion force generated when the first magnetic pole portion 131 and the second magnetic pole portion 132 of the first magnetic member 130 are incorrectly aligned with the second magnetic member 230 of the plug is used to hinder the insertion, thereby achieving magnetic attraction prevention, preventing reverse insertion, avoiding pin damage, improving reliability, and extending service life. Moreover, the magnetic attraction force of the first magnetic member 130 is enhanced by the first magnetic reflector 140, making the connection between the plug and the socket more secure and stable, thereby improving reliability.

[0064] In one embodiment, the first magnetic pole portion 131 and the second magnetic pole portion 132 are symmetrically distributed on both sides of the first electrical connector 120. Specifically, the first magnetic pole portion 131 and the second magnetic pole portion 132 of the first magnetic member 130 are symmetrically distributed relative to the first electrical connector 120. The first magnetic pole portion 131 and the second magnetic pole portion 132 can be symmetrically distributed on the left and right sides of the first electrical connector 120, or can be symmetrically distributed on the upper and lower sides of the first electrical connector 120. The first magnetic member 130 can be various symmetric structures. For example, the first magnetic member 130 can be a C-shaped or U-shaped symmetric structure. For example, the first magnetic member 130 is in an inverted "C" shape, divided by a horizontal center line. Among them, the upper half of the inverted "C" shape is "┍", and the lower half is "└". "┍" can be the first magnetic pole portion 131, and "└" can be the second magnetic pole portion 132. The first electrical connector 120 is surrounded in the center of the inverted "C" shape. Thus, the first magnetic pole portion 131 and the second magnetic pole portion 132 can be symmetrically distributed on the upper and lower sides of the first electrical connector 120. Another example, the first magnetic member 130 is in a "コ" shape, and its structural principle is the same as the previous example and will not be elaborated here. Another example, the first magnetic member 130 is in a "凵" shape, divided by a vertical center line. Among them, the left half of the "凵" shape is "┕", and the right half is "┘". "┕" can be the first magnetic pole portion 131, and "┘" can be the second magnetic pole portion 132. The first electrical connector 120 is surrounded in the center of the "凵" - shaped first magnetic member 130. Thus, the first magnetic pole portion 131 and the second magnetic pole portion 132 can be symmetrically distributed on the left and right sides of the first electrical connector 120. Another example, the first magnetic member 130 is in a "冂" shape, and its structural principle is the same as the previous example and will not be elaborated here. Then, the first magnetic pole portion 131 and the second magnetic pole portion 132 can generate magnetic suction force on the left and right sides or the upper and lower sides of the first electrical connector 120. Since the magnetic suction force is generated on the left and right sides or the upper and lower sides of the first electrical connector 120, it can guide and attract the charging coupler plug 200 to be inserted while guiding and correcting its second electrical connector 220, so that the second electrical connector 220 of the charging coupler plug 200 can be accurately aligned with the first electrical connector 120, achieving accurate plugging and unplugging and improving reliability.

[0065] In one embodiment, the first magnetic member 130 is annular, and the first magnetic member 130 is arranged around the outer periphery of the first electrical connector 120. Specifically, the shape of the first magnetic member 130 is annular as a whole, for example, it can be a circular ring, an elliptical ring, a rectangular ring or other polygonal ring, etc., which is not limited here. The first magnetic member 130 is arranged around the first electrical connector 120 to surround the first electrical connector 120. By setting the annular first magnetic member 130 around the first electrical connector 120, there is a magnetic field all around the first electrical connector 120, the area of ​​the magnetic field is larger, the magnetic field intensity is greater, and the magnetic attraction force generated is relatively greater, which can make the connection between the plug and the socket more secure, and can avoid medical accidents caused by accidental pulling that causes the plug and the socket to separate.

[0066] In this embodiment, the first magnetic member 130 is a rectangular ring magnet, and the first magnetic pole portion 131 and the second magnetic pole portion 132 are symmetrically distributed relative to the horizontal center line / vertical center line / diagonal line of the rectangular ring magnet. Specifically, the first magnetic member 130 of this embodiment is a rectangular ring magnet structure, and the first electrical connector 120 is provided in the inner circle of the rectangular ring magnet. The first magnetic pole portion 131 and the second magnetic pole portion 132 can be distributed on the rectangular ring magnet in the following three ways: one is symmetrically distributed along the horizontal center line of the rectangular ring magnet, such as Figure 4a As shown in the figure, the dotted line is the horizontal center line of the rectangular ring magnet. The rectangular ring magnet is divided into two parts by the horizontal center line. The upper half is the first magnetic pole part 131, and the lower half is the second magnetic pole part 132. The upper half is the N pole and the lower half is the S pole. Of course, it can be understood that the upper half can also be the S pole and the lower half can be the N pole. Another method is to symmetrically distribute along the vertical center line of the rectangular ring magnet, such as Figure 4b As shown in the figure, the dotted line is the vertical center line of the rectangular ring magnet. The rectangular ring magnet is divided into two parts by the vertical center line. The left half is the first magnetic pole part 131, and the right half is the second magnetic pole part 132. The left half is the N pole and the right half is the S pole. Of course, it can be understood that the left half can also be the S pole and the right half can be the N pole. Another method is to distribute along the diagonal line of the rectangular ring magnet, such as Figure 4cAs shown, the dotted line in the figure represents the diagonal of the rectangular ring magnet. The rectangular ring magnet is divided into two oblique parts by the diagonal line. The diagonal line can extend from the lower left corner to the upper right corner of the rectangular ring magnet, with the upper left half being the north pole and the lower right half being the south pole. Of course, it is understood that the upper left half can also be the south pole and the lower right half the north pole. Furthermore, the diagonal line can also extend from the lower right corner to the upper left corner of the rectangular ring magnet, with the lower left half being the north pole and the upper right half being the south pole. Of course, it is understood that the lower left half can also be the south pole and the upper right half the north pole. It should be noted that the two symmetrically distributed parts of the rectangular ring magnet are magnetized separately, for example, using a magnetizer to magnetize the two parts separately to enhance the magnetism of the two parts. In other embodiments, magnets can also be placed at the four corners. By using the above-mentioned symmetrically distributed rectangular ring magnets, a uniform magnetic field distribution of two different polarities is formed around the first electrical connector 120, resulting in a simple structure and low processing difficulty.

[0067] In this embodiment, the first magnetic reflector 140 is a sheet-like body, and the first magnetic reflector 140 is adsorbed on the side of the first magnetic part 130 facing away from the first plug-in end face 111. Specifically, the first magnetic reflector 140 is a sheet-like structure, which has a certain magnetism and can be magnetically attracted to the first magnetic part 130. The sheet-like structure of this embodiment can be a metal sheet-like body, for example, it can be an iron sheet, which is not limited here. The shape of the first magnetic reflector 140 matches the shape of the first magnetic part 130. For example, if the first magnetic part 130 is in the shape of a rectangular ring, then the first magnetic reflector 140 is also in the shape of a rectangular ring. Since the first magnetic reflector 140 is made of metal, the first magnetic reflector 140 can be magnetically adsorbed on the back side of the first magnetic part 130. In actual processing, the first magnetic reflector 140 can be adsorbed on the back side of the first magnetic part 130 and the two can be injection molded into one piece for easy processing.

[0068] In one embodiment, a protrusion 151 is provided in the female socket 110, and the protrusion 151 is higher than the first plug-in end face 111, and the first electrical connector 120 is inserted into the protrusion 151. Specifically, the protrusion 151 is used to fix the first electrical connector 120, and the protrusion 151 protrudes from the first plug-in end face 111. A plurality of channels are provided in the protrusion 151 in a direction perpendicular to the first plug-in end face 111, and a plurality of first electrical connectors 120, that is, a plurality of pins, are inserted into each channel one by one. When the female socket 110 is combined with the male connector 210, the protrusion 151 on the female socket 110 cooperates with the recessed portion 251 on the male connector 210 to assist in alignment and plugging, and improve the reliability of the connection.

[0069] Reference Figure 8In this embodiment, the charging coupler socket 100 further includes a first pin holder 150, which is disposed within the female socket 110. The protrusion 151 is a portion of the first pin holder 150. Specifically, the first pin holder 150 includes a protrusion 151 and a recessed portion. The protrusion 151 protrudes from the first plugging end surface 111 of the female socket 110, while the recessed portion is recessed within the female socket 110. One end of the pin is inserted through the protrusion 151, while the other end of the pin passes through the recessed portion and the female socket 110 and is electrically connected to the circuit board within the housing of the ultrasound device 300. The first magnetic member 130 and the first magnetic reflector 140 are arranged in the female socket 110 around the first pin holder 150. By providing the first pin holder 150 to secure the first electrical connector 120, the first electrical connector 120 remains stable, improving connection reliability. Furthermore, the first pin holder 150 separates the first electrical connector 120 from the first magnetic member 130, preventing magnetic interference. It should be noted that the first pin holder 150 and the female connector 110 can be integrally formed or formed as two separate components.

[0070] Reference Figure 8 In one embodiment, the first electrical connector 120 includes a first power supply pin and a first signal pin, and the first power supply pin is higher than the first signal pin. Specifically, the first electrical connector 120 may include a plurality of pins, which may include a first power supply pin for connecting a power source and a first signal pin for transmitting a signal. The first power supply pin and the first signal pin are both arranged in the channel of the first pin fixing seat 150 (protrusion 151), and the setting depth of the first power supply pin and the first signal pin is different. The first signal pin is sunk deeper than the first power supply pin, and therefore, the first power supply pin is higher than the first signal pin. In this way, when contacting the pin of the male connector, the first power supply pin contacts first and the first signal pin contacts later, thereby avoiding damage to the internal chip caused by connecting the first signal pin first, thereby improving reliability.

[0071] In this embodiment, the two opposite edges of the first pin fixing seat 150 (protrusion 151) are asymmetric. In order to further achieve foolproofing, the first pin fixing seat 150 is set to a structure with asymmetric edges on both sides, for example, the upper and lower edges are asymmetric, or the left and right edges are asymmetric. For example, the first pin fixing seat 150 is a trapezoidal structure, and its left and right sides are asymmetric. Then, when the plug is inserted upside down, the plug cannot be inserted due to the asymmetric structure of the first pin fixing seat 150. For another example, the first pin fixing seat 150 is a structure with asymmetric protrusions on the upper and lower sides, and its upper and lower sides are asymmetric. Then, when the plug is inserted upside down, the plug cannot be inserted due to the asymmetric structure of the first pin fixing seat 150. The double foolproofing structure formed by the asymmetric first pin fixing seat 150 and the first magnetic member 130 further improves the reliability of anti-reverse insertion.

[0072] In the actual manufacturing of the charging coupler socket 100 of this embodiment, the rectangular ring magnet and the first magnetic reflector 140 are embedded in the female socket 110 through insert injection molding. During injection molding, the rectangular ring magnet is positioned by the inner ring of the rear mold and fixed by adsorption between the rectangular ring magnet and the core of the rear mold. The first magnetic reflector 140 is attracted to the rectangular ring magnet, and the first pin fixing seat 150 is placed on the sink of the front mold. After injection molding, the female socket 110 is formed, so that the female socket 110, the first pin fixing seat 150, the rectangular ring magnet, and the first magnetic reflector 140 are injection molded as a whole. Of course, it is understood that the charging coupler socket 100 can also be processed and installed in other ways.

[0073] Reference Figure 5 - Figure 7. An embodiment of the present invention further provides a charging coupler plug 200, comprising: a male connector 210, a second electrical connector 220, and a second magnetic component 230; the male connector 210 having a second plugging end surface 211; the second electrical connector 220 disposed in the male connector 210 and exposed on the second plugging end surface 211; the second magnetic component 230 disposed in the male connector 210 and adjacent to the second electrical connector 220, the second magnetic component 230 having a third magnetic pole portion 231 and a fourth magnetic pole portion 232, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 having opposite polarities, and the third magnetic pole portion 231 and the fourth magnetic pole portion 232 being distributed in a direction parallel to the second plugging end surface 211; and a second magnetic reflector 240 disposed on a side of the second magnetic component 230 facing away from the second plugging end surface 211.

[0074] Specifically, the male connector 210 is used to connect to a power adapter via a cable 270 to access the mains power supply. The male connector 210 is in the shape of a rectangular shell as a whole. The front side of the rectangular shell is the second plug-in end face 211 of the male connector 210, and the adjacent side adjacent to the front side of the rectangular shell is connected to the cable 270. The second electrical connector 220 is a pin, that is, a pin needle. The pin is inserted into the rectangular shell in a direction perpendicular to the second plug-in end face 211. The first end of the pin is exposed on the second plug-in end face 211 and is used to mate with the socket. The other end of the pin is electrically connected to the cable 270. It should be noted that the pin is exposed on the second plug-in end face 211, which means that the pin is not completely enclosed in the male connector 210. The pin can be lower than the second plug-in end face 211, or it can be higher or flush, as long as it can be exposed on the male connector 210 and connected in place with the first electrical connector 120. The second magnetic part 230 can be a magnet. The arrangement of the second magnetic member 230 in the male connector 210 can be similar to the arrangement of the first magnetic member 130 in the female connector 110. The second magnetic member 230 is disposed inside the male connector 210, closely adjacent to the second plug end face 211. Furthermore, the second magnetic member 230 is adjacent to the second electrical connector 220 in the male connector 210, so that the second magnetic member 230 can generate a magnetic field around the second electrical connector 220. Specifically, the second magnetic member 230 has two magnetic pole portions with opposite polarities, namely a third magnetic pole portion 231 and a fourth magnetic pole portion 232. For example, the third magnetic pole portion 231 is an N pole, and the fourth magnetic pole portion 232 is an S pole. Alternatively, the third magnetic pole portion 231 is an S pole, and the fourth magnetic pole portion 232 is an N pole. The second magnetic member 230 is generally parallel to the second plugging end face 211, and the third magnetic pole portion 231 and the fourth magnetic pole portion 232 are arranged in a direction parallel to the second plugging end face 211. That is, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 are arranged horizontally, rather than vertically, relative to the second plugging end face 211. Therefore, a single second magnetic member 230 can generate two magnetic positions with opposite polarities on the second plugging end face 211: one magnetic position is the N-pole magnetic position, which attracts magnetic objects with the S-pole and repels magnetic objects with the N-pole; the other magnetic position is the S-pole magnetic position, which attracts magnetic objects with the N-pole and repels magnetic objects with the S-pole. Therefore, when inserted into the charging coupler receptacle 100, assume that the third magnetic pole portion 231 of the second magnetic member 230 is the N-pole and the fourth magnetic pole portion 232 is the S-pole; and the first magnetic pole portion 131 of the first magnetic member 130 is the S-pole and the second magnetic pole portion 132 is the N-pole.Only when the third magnetic pole portion 231 aligns with the first magnetic pole portion 131 and the fourth magnetic pole portion 232 aligns with the second magnetic pole portion 132, like poles attract, allowing insertion into the charging coupler receptacle 100. However, when the third magnetic pole portion 231 aligns with the second magnetic pole portion 132 and the fourth magnetic pole portion 232 aligns with the first magnetic pole portion 131, opposite poles repel, preventing insertion into the charging coupler receptacle 100. This indicates that the charging coupler plug 200 has been inserted incorrectly, thus preventing incorrect insertion and providing a magnetic error prevention function. Due to size and weight constraints, the male connector 210 is often designed to be relatively small, resulting in a smaller internal space within the male connector 210. Consequently, the volume of the second magnetic member 230 is also limited by this internal space. Consequently, its magnetic field strength is often weak, resulting in insufficient magnetic attraction. In order to enhance the magnetic attraction of the second magnetic member 230, in this embodiment, a second magnetic reflector 240 is provided on the side of the second magnetic member 230 facing away from the second plug-in end face 211, that is, on the back side of the second magnetic member 230. The second magnetic reflector 240 can be fixed to the back side of the second magnetic member 230 by welding, bonding, adsorption, or installation with a fixing member. The magnetic reflector shields the magnetic flux leakage from the second magnetic member 230 to the back side, prevents the magnetic flux from leaking to the back side, and reflects the magnetic flux to the second plug-in end face 211, thereby enhancing the magnetic attraction of the second magnetic member 230, making the second magnetic member 230 more firmly bonded to the first magnetic member 130 of the charging coupler socket 100, thereby improving reliability.

[0075] In this embodiment, a second magnetic member 230 is provided in the male connector 210. The magnetic attraction force generated when the third magnetic pole portion 231 and the fourth magnetic pole portion 232 of the second magnetic member 230 are correctly aligned with the first magnetic member 130 is used to guide insertion, thereby achieving convenient and accurate plugging and unplugging operations. The connection is effective and reliable, and can prevent medical accidents caused by accidental pulling that may cause the socket and plug to separate. At the same time, the magnetic repulsion force generated when the third magnetic pole portion 231 and the fourth magnetic pole portion 232 of the second magnetic member 230 are incorrectly aligned with the first magnetic member 130 is used to hinder insertion, thereby achieving magnetic attraction prevention, preventing reverse insertion, avoiding pin damage, improving reliability, and extending service life. Moreover, the magnetic attraction force of the second magnetic member 230 is enhanced by the second magnetic reflector 240, making the connection between the plug and the socket more secure and stable, thereby improving reliability.

[0076] In one embodiment, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 are symmetrically distributed on both sides of the second electrical connector 220. Specifically, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 of the second magnetic member 230 are symmetrically distributed relative to the second electrical connector 220. The third magnetic pole portion 231 and the fourth magnetic pole portion 232 can be symmetrically distributed on the left and right sides of the second electrical connector 220, or can be symmetrically distributed on the upper and lower sides of the second electrical connector 220. The second magnetic member 230 can be various symmetrical structures. For example, the second magnetic member 230 can be a C-shaped or U-shaped symmetrical structure. For example, the second magnetic member 230 is in the shape of "匚". Divided by the horizontal center line, where the upper half of the "匚" shape is "┍", and the lower half is "└". "┍" can be the third magnetic pole portion 231, and "└" can be the fourth magnetic pole portion 232. The second electrical connector 220 is surrounded in the center of the "匚" shape. In this way, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 can be symmetrically distributed on the upper and lower sides of the second electrical connector 220. Another example, the second magnetic member 230 is in the shape of "コ", and its structural principle is the same as the previous example, which will not be elaborated here. Another example, the second magnetic member 230 is in the shape of "凵". Divided by the vertical center line, where the left half of the "凵" shape is "┕", and the right half is "┘". "┕" can be the third magnetic pole portion 231, and "┘" can be the fourth magnetic pole portion 232. The second electrical connector 220 is surrounded in the center of the second magnetic member 230 in the shape of "凵". In this way, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 can be symmetrically distributed on the left and right sides of the second electrical connector 220. Another example, the second magnetic member 230 is in the shape of "冂", and its structural principle is the same as the previous example, which will not be elaborated here. Then, the third magnetic pole portion 231 and the fourth magnetic pole portion 232 can generate magnetic suction forces on the left and right sides or the upper and lower sides of the second electrical connector 220. Since the magnetic suction forces are generated on the left and right sides or the upper and lower sides of the second electrical connector 220, the second electrical connector 220 can be aligned during the magnetic suction process with the second magnetic member 230, so that the second electrical connector 220 can be accurately aligned with the first electrical connector 120, achieving accurate plugging and unplugging and improving reliability.

[0077] In one embodiment, the second magnetic member 230 is annular, and the second magnetic member 230 is arranged around the outer periphery of the second electrical connector 220. Specifically, the shape of the second magnetic member 230 is annular as a whole, for example, it can be a circular ring, an elliptical ring, a rectangular ring or other polygonal ring, etc., which is not limited here. The second magnetic member 230 is arranged around the second electrical connector 220 to surround the second electrical connector 220. By setting the annular second magnetic member 230 around the second electrical connector 220, there is a magnetic field all around the second electrical connector 220, the area of ​​the magnetic field is larger, the magnetic field intensity is greater, and the magnetic attraction force generated is relatively greater, which can make the connection between the plug and the socket more secure, and can avoid accidental pulling that causes the plug and the socket to separate and cause medical accidents.

[0078] In this embodiment, the second magnetic member 230 is a rectangular ring magnet, and the third magnetic pole portion 231 and the fourth magnetic pole portion 232 are symmetrically distributed relative to the horizontal center line / vertical center line / diagonal line of the rectangular ring magnet. Specifically, the second magnetic member 230 of this embodiment is a rectangular ring magnet structure, and the second electrical connector 220 is provided in the inner circle of the rectangular ring magnet. The third magnetic pole portion 231 and the fourth magnetic pole portion 232 can be distributed on the rectangular ring magnet in the following three ways. One is to be symmetrically distributed along the horizontal center line of the rectangular ring magnet, such as Figure 7a As shown in the figure, the dotted line is the horizontal center line of the rectangular ring magnet. The rectangular ring magnet is divided into two parts by the horizontal center line. The upper half is the third magnetic pole portion 231, and the lower half is the fourth magnetic pole portion 232. The upper half is the N pole and the lower half is the S pole. Of course, it can be understood that the upper half can also be the S pole and the lower half can be the N pole. Another method is to symmetrically distribute along the vertical center line of the rectangular ring magnet, such as Figure 7b As shown in the figure, the dotted line is the vertical center line of the rectangular ring magnet. The rectangular ring magnet is divided into two parts by the vertical center line. The left half is the third magnetic pole part 231, and the right half is the fourth magnetic pole part 232. The left half is the N pole and the right half is the S pole. Of course, it can be understood that the left half can also be the S pole and the right half can be the N pole. Another method is to distribute along the diagonal line of the rectangular ring magnet, such as Figure 7cAs shown, the dotted line in the figure represents the diagonal of the rectangular ring magnet. The rectangular ring magnet is divided into two oblique parts by the diagonal line. The diagonal line can extend from the lower left corner to the upper right corner of the rectangular ring magnet, with the upper left half being the north pole and the lower right half being the south pole. Of course, it is understood that the upper left half can also be the south pole and the lower right half the north pole. Furthermore, the diagonal line can also extend from the lower right corner to the upper left corner of the rectangular ring magnet, with the lower left half being the north pole and the upper right half being the south pole. Of course, it is understood that the lower left half can also be the south pole and the upper right half the north pole. It should be noted that the two symmetrically distributed parts of the rectangular ring magnet are magnetized separately, for example, using a magnetizer to magnetize the two parts separately to enhance the magnetism of the two parts. In other embodiments, magnets can also be placed at the four corners. By using the above-described symmetrically distributed rectangular ring magnets, a uniform magnetic field distribution of two different polarities is formed around the second electrical connector 220, resulting in a simple structure and low processing difficulty.

[0079] In this embodiment, the second magnetic reflector 240 is a sheet-like body, and the second magnetic reflector 240 is adsorbed on the side of the second magnetic part 230 facing away from the second plug-in end face 211. Specifically, the second magnetic reflector 240 is a sheet-like structure, which has a certain magnetism and can be magnetically attracted to the first magnetic part 130. The sheet-like structure of this embodiment can be a metal sheet-like body, for example, it can be an iron sheet, which is not limited here. The shape of the second magnetic reflector 240 matches the shape of the second magnetic part 230. For example, if the second magnetic part 230 is in the shape of a rectangular ring, then the second magnetic reflector 240 is also in the shape of a rectangular ring. Since the second magnetic reflector 240 is made of metal, the second magnetic reflector 240 can be magnetically adsorbed on the back side of the second magnetic part 230. In actual processing, the second magnetic reflector 240 can be adsorbed on the back side of the second magnetic part 230 and the two can be injection molded into one piece for easy processing.

[0080] In one embodiment, a recessed portion 251 is provided in the male connector 210, and the recessed portion 251 is lower than the second plug-in end face 211, and the second electrical connector 220 is inserted into the recessed portion 251. Specifically, the recessed portion 251 is used to fix and install the second electrical connector 220, and the recessed portion 251 is recessed relative to the second plug-in end face 211. A plurality of channels are provided in the recessed portion 251 in a direction perpendicular to the second plug-in end face 211, and a plurality of second electrical connectors 220, that is, a plurality of pins, are inserted into each channel one by one. When the male connector 210 is combined with the female connector 110, the recessed portion 251 on the male connector 210 cooperates with the protruding portion 151 on the female connector 110 to assist in alignment and plugging, and improve the reliability of the connection.

[0081] In this embodiment, the charging coupler plug also includes a second pin holder 250, which is disposed in the male connector 210. The recess 251 is a portion of the second pin holder 250. Specifically, the second pin holder 250 is entirely sunken into the interior of the male connector relative to the second plugging end face 211, with a portion of the recess 251 being recessed relative to the second plugging end face 211. The second plugging end face 211 is formed with a notch, through which the pin is aligned with the female connector 110 of the charging coupler socket 100 for insertion. One end of the pin is exposed in the notch of the second plugging end face 211, and the other end of the pin passes through the second pin holder 250 to connect with the cable 270. The second magnetic member 230 and the second magnetic reflector 240 are arranged in the male connector 210 around the second pin holder 250. The second pin holder 250 secures the second electrical connector 220, maintaining its stability and improving connection reliability. Furthermore, the second pin holder 250 separates the second electrical connector 220 from the second magnetic member 230, preventing magnetic interference. It should be noted that the second pin holder 250 and the male connector 210 can be integrally formed or formed as two separate components.

[0082] In this embodiment, the opposite edges of the second pin holder 250 (recess 251) are asymmetric. Specifically, the shape of the second pin holder 250 matches the shape of the first pin holder 150. To further achieve foolproofing, the second pin holder 250 is configured to have asymmetric edges on both sides, for example, the upper and lower edges are asymmetric, or the left and right edges are asymmetric. For example, the second pin holder 250 is a trapezoidal structure with asymmetric left and right sides. Then, when the plug is inserted upside down, the plug cannot be inserted due to the asymmetric structure of the second pin holder 250. For another example, the second pin holder 250 is a structure with asymmetric protrusions on the upper and lower sides. The upper and lower sides are asymmetric. Then, when the plug is inserted upside down, the plug cannot be inserted due to the asymmetric structure of the second pin holder 250. The asymmetric second pin holder 250 and the second magnetic member 230 form a double foolproofing structure, further improving the reliability of anti-reverse insertion.

[0083] In this embodiment, the second electrical connector 220 includes a second power supply pin 221 and a second signal pin 222, with the second power supply pin 221 being higher than the second signal pin 222. Specifically, the second electrical connector 220 may include multiple types of pins, including a second power supply pin 221 and a second signal pin 222. The second power supply pin 221 and the second signal pin 222 are both disposed in the channel of the second pin fixing seat 250 (the recessed portion 251). The second power supply pin 221 and the second signal pin 222 are sunk into the recessed portion 251 to different depths. The second signal pin 222 is sunk deeper than the second power supply pin 221, and therefore the second power supply pin 221 is higher than the second signal pin 222. Thus, when the device is plugged into the charging coupler socket 100, the second power pin 221 makes contact first, followed by the second signal pin 222. This prevents damage to the internal chip caused by the signal pins making contact first. In addition, establishing a power connection before the second signal pin 222 makes contact allows time for the device to initialize or activate its protection circuit. Furthermore, ensuring a stable power supply before data transmission begins can prevent data packet loss or corruption. If data transmission begins before the power supply is stable, data errors may result.

[0084] In one embodiment, the charging coupler plug 200 further includes a housing 260, which covers the outer periphery of the male connector 210 and is provided with an anti-slip portion 261. Specifically, the housing 260 of this embodiment is generally U-shaped, with an opening facing the side. The housing 260 covers the outer periphery of the male connector 210, with the upper and lower sides of the male connector 210 covered by the housing 260, leaving the male connector 210 exposed on the outer periphery of the housing 260. Anti-slip portions 261 are provided on the upper or lower side, or on both sides of the male connector 210. These anti-slip portions 261 are recessed into the male connector 210, creating a gripping area for the user's hand, facilitating insertion and removal.

[0085] In the actual processing of the charging coupler plug 200 of this embodiment, the second pin holder 250 is first injection molded, and then the second electrical connector 220 is assembled to the second pin holder 250. The second magnetic member 230 is then fixed to the second pin holder 250. The second magnetic reflector 240 is attracted to the second magnetic member 230. The second electrical connector 220 is then welded to the copper wire in the cable 270 and then placed together in a mold to injection mold the male connector 210. The U-shaped housing 260 is designed with a plug-in anti-slip portion 261 and is joined to the injection molded male connector 210 by ultrasonic welding. Of course, it is understood that the charging coupler plug 200 of this embodiment can also be processed and assembled in other ways, which are not limited here.

[0086] The present invention also provides a charging coupler, comprising the charging coupler socket 100 and the charging coupler plug 200 of the aforementioned embodiment. The first magnetic pole portion 131 and the third magnetic pole portion 231 have opposite polarities, thereby magnetically attracting each other. The second magnetic pole portion 132 and the fourth magnetic pole portion 232 have opposite polarities, thereby magnetically attracting each other. Specifically, the charging coupler socket 100 and the charging coupler plug 200 have been described in detail in the aforementioned embodiment and will not be further described here for the sake of brevity.

[0087] Through this embodiment, the first magnetic pole portion 131 and the second magnetic pole portion 132 of the first magnetic member 130 are attracted to each other with the same polarity or repelled from each other with the third magnetic pole portion 231 and the fourth magnetic pole portion 232 of the second magnetic member 230 respectively to achieve the aligned plugging and misaligned repulsion of the charging coupler socket 100 and the charging coupler plug 200. This can not only prevent magnetic errors but also facilitate and quickly perform charging and discharging plugging and unplugging operations, thereby ensuring plugging and unplugging reliability and extending service life.

[0088] Reference Figure 10 The present invention also provides an ultrasound system comprising the charging coupler of the aforementioned embodiment and an ultrasound device 300. The charging coupler socket 100 is mounted on the ultrasound device 300, and the charging coupler plug 200 is configured to couple with and plug into the charging coupler socket 100. Specifically, the ultrasound device 300 is a portable ultrasound device, and the charging coupler has been described in detail in the aforementioned embodiment. For the sake of brevity, further details will not be given here.

[0089] Through this embodiment, the above-mentioned charging coupler with magnetic anti-foolproofing function is adopted, which improves the reliability of the ultrasonic equipment 300 during charging and discharging plugging and unplugging operations, effectively prevents reverse plugging, avoids damage to the pins, and realizes plugging and unplugging conveniently and quickly with stable contact.

[0090] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
