The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).

The application provides an electric signal butt-joint structure. The electrical signal interfacing structure is used to enable the transfer of electrical signals, such as power or other data. The electric signal docking structure can be applied to, but is not limited to, medical equipment, and can also be applied to other electronic equipment. The following description will mainly use a portable ultrasound device as an example to clearly illustrate the electrical signal docking structure presented in the present application. Of course, the electrical signal docking structure shown in this embodiment may also be applied to other devices besides the portable ultrasound device, such as a desktop ultrasound device, a monitoring device, and other medical devices.

Referring to fig. 1 and 2, in one embodiment, the portable ultrasound device includes a host 1000. The host 1000 has a housing 100, a control unit (not shown in the figure), and an electrical signal docking structure 200. Of course, the host 1000 may further include various structures such as a power circuit, a display device, etc., which are known to those skilled in the art and will not be described further herein.

With continued reference to fig. 1 and 2, in the portable ultrasound device, the electrical signal docking structure 200 includes a magnetic socket 210 and a magnetic plug 220, which are magnetically coupled to each other for docking. As shown in FIGS. 1 and 2, when the magnetically attractive plug 220 approaches the magnetically attractive socket 210 to a certain distance, the two automatically attract together.

Referring to fig. 3, 5 and 6, in one embodiment, the magnetic socket 210 includes a base 211, a first electrical signal connector 212, a first magnetic member 213 and a second magnetic member 214. The seat 211 is a support structure for the entire magnet socket 210 and has a first mating surface 2111 for mating with a corresponding magnet plug 220. The shape of the seat 211 can be designed according to the requirements of the assembly space and other components, and is not limited to the shape shown in the embodiment. The first electrical signal connector 212 is mounted on the base 211 and exposed from the first mating surface 2111. The first electrical signal connector 212 is connected to a control unit of a medical device, such as a portable ultrasound device, for transferring electrical signals. When the first electrical signal connector 212 is connected to the magnetic plug 220, the control unit is connected to the magnetic plug 220, so as to transmit or interact electrical signals between the control unit and the magnetic plug 220.

The first magnetic element 213 and the second magnetic element 214 are mounted on the base 211 and distributed at the side of the first electrical signal connector 212. As shown in fig. 5 and 6, in one embodiment, the first magnetic member 213 and the second magnetic member 214 are symmetrically disposed on both sides of the first electrical signal connector 212. However, the side portions are not necessarily symmetrically disposed, and the first magnetic member 213 and the second magnetic member 214 may be disposed on the same side or multiple sides of the first electrical signal connector 212. The first magnetic member 213 and the second magnetic member 214 have opposite polarities at the end facing the first mating surface 2111, that is, the first magnetic member 213 and the second magnetic member 214 have opposite polarities at the end for attracting the magnetic plug 220, so as to form different polarity distributions, which can be attracted by the magnetic socket 210 only when the magnetic member on the magnetic plug 220 matches with the polarity distributions.

Referring to fig. 4, 5 and 6, in one embodiment, the magnetically attractive plug 220 includes a first mating end 221, a second mating end (not shown), and a cable 222. The first and second mating ends 221 and 222 are connected via a cable for transmitting electrical signals.

The first mating end 221 is used for mating with the socket 210, and the second mating end is used for mating with other components, such as a power strip or other electrical signal transmission or reception device. The structure of the second docking end is not limited in this embodiment, and may be various structures capable of implementing electrical signal docking, and may also be used in various structures requiring electrical signal transmission.

With continued reference to fig. 4, 5, and 6, in one embodiment, the first docking end 221 includes a body 2211, a second electrical signal connector 2212, a third magnetic component 2213, and a fourth magnetic component 2214. The header body 2211 has a second mating surface 2215 for mating with a corresponding receptacle. The second interface surface 2215 and the first interface surface 2111 are substantially flush when the magnet socket 210 is mated with the magnet plug 220. The header body 2211 is a support structure for the first mating end 221, and the second electrical signal connector 2212 is mounted on the header body 2211 and exposed at the second mating surface 2215 for mating with the first electrical signal connector 212. In some embodiments, removable shields can be provided for the exposed portions of the first electrical signal connector 212 and the second electrical signal connector 2212 to prevent other objects from wearing the first electrical signal connector 212 and the second electrical signal connector 2212.

The third and fourth

magnetic members

2213 and 2214 are mounted on the head body 2211 and distributed at the sides of the second electrical signal connector 2212. Also, as shown in fig. 5 and 6, in one embodiment, the third magnetic element 2213 and the fourth magnetic element 2214 are symmetrically disposed on both sides of the second electrical signal connector 2212. However, the side portions are not necessarily symmetrically disposed, and the third magnetic member 2213 and the fourth magnetic member 2214 may be disposed on the same side or multiple sides of the second electrical signal connector 2212. The third magnetic member 2213 and the fourth magnetic member 2214 have opposite polarities toward one end of the second docking surface 2215. That is, the third magnetic member 2213 and the fourth magnetic member 2214 are used to attract one end of the magnetic socket 210 with opposite polarities so as to form a differentiated polarity distribution. The first magnetic member 213 of the socket 210 and the third magnetic member 2213 of the plug 220 have opposite polarities, and the second magnetic member 214 of the socket 210 and the fourth magnetic member 2214 of the plug 220 have opposite polarities, so as to attract each other. The magnetic member on the socket 210 can be attracted by the plug 220 only when the magnetic member matches the polarity distribution of the plug 220.

For example, referring to fig. 5, in one embodiment, the end of the first magnetic member 213 abutting against the third magnetic member 2213 is S-pole, and the end of the third magnetic member 2213 abutting against the first magnetic member 213 is N-pole. The end of the second magnetic member 214 that is abutted against the fourth magnetic member 2214 is N-pole, and the end of the fourth magnetic member 2214 that is abutted against the second magnetic member 214 is S-pole.

For another example, referring to fig. 6, in another embodiment, the end of the first magnetic member 213 abutting against the third magnetic member 2213 is an N pole, and the end of the third magnetic member 2213 abutting against the first magnetic member 213 is an S pole. The end of the second magnetic member 214 abutting against the fourth magnetic member 2214 is S-pole, and the end of the fourth magnetic member 2214 abutting against the second magnetic member 214 is N-pole.

In the electrical signal docking structure 200 shown in this embodiment, the magnetism of each magnetic member on the docking surface is different, and the magnetic socket 210 and the magnetic plug 220 can be accurately attracted to the correct position, so as to ensure the accuracy of the docking position, improve the convenience of docking, and enable a user to perform blind operation, i.e., without looking at the docking position for plugging and unplugging. In addition, the polarity distribution characteristics of the magnetic socket 210 and the magnetic plug 220 can also play a fool-proof role, when the magnetic plug 220 is docked with the magnetic socket 210 in a manner of rotating and deviating a certain angle from the normal docking position, if the rotating and deviating angle is not large, the magnetic force of each magnetic piece can be automatically adjusted to the correct position for docking. If the rotation deviation angle is too large, for example, 180 °, the magnetic member on the magnetic plug 220 and the magnetic member on the magnetic socket 210 are not matched in polarity, and the attraction cannot be realized, so that the user can be prevented from butting the magnetic plug 220 with the magnetic socket 210 in a wrong manner, and the potential safety hazard is avoided.

Referring to fig. 5 and 6, in one embodiment, the first magnetic member 213 and the second magnetic member 214 are symmetrically distributed around the first electrical signal connector 212. The third and fourth

magnetic members

2213 and 2214 are symmetrically distributed around the second electrical signal connector 2212. The symmetrically distributed magnetic members enable the attraction points of the magnetic socket 210 and the magnetic plug 220 to be symmetrically distributed around the first telecommunication connector and the second electric signal connector 2212, so that the attraction of the magnetic socket 210 and the magnetic plug 220 is more stable. However, the magnetic member is not necessarily disposed around the corresponding electrical signal connector in a symmetrical manner, but may be disposed on one or more sides of the corresponding electrical signal connector, which may depend on the actual attracting requirement.

With continued reference to fig. 5 and 6, in one embodiment, the first magnetic member 213 and the second magnetic member 214 are both disposed symmetrically on both sides of the first electrical signal connector 212. The third and fourth

magnetic members

2213 and 2214 are each one and symmetrically disposed on both sides of the second electrical signal connector 2212.

In addition to the magnetic members symmetrically disposed on the upper and lower sides of the corresponding electrical signal connector as shown in fig. 5 and 6, the magnetic members may also be disposed on the left and right sides of the corresponding electrical signal connector.

Of course, there is not only one first magnetic member 213, second magnetic member 214, third magnetic member 2213, and fourth magnetic member 2214, but also two or more of them may be partially or entirely provided.

In one embodiment, the number of the first magnetic members 213 is at least two, and the polarities of the ends of all the first magnetic members 213 facing the first docking surface 2111 are the same and are adjacently disposed. For example, in the structure shown in fig. 5 and 6, the number of the first magnetic members 213 is increased to two or more, and the increased first magnetic members 213 are adjacently disposed. Or in an embodiment, there are at least two second magnetic members 214, and all ends of the second magnetic members 214 facing the first butting face 2111 have the same polarity and are adjacently disposed. For example, in the structure shown in fig. 5 and 6, the number of the second magnetic members 214 is increased to two or more, and these increased second magnetic members 214 are also adjacently disposed.

Similarly, in one embodiment, there are at least two third magnetic members 2213, and all the third magnetic members 2213 have the same polarity at the end facing the second abutting surface 2215 and are disposed adjacently. Alternatively, in an embodiment, there are at least two fourth magnetic members 2214, and all the fourth magnetic members 2214 have the same polarity at the end facing the second docking surface 2215 and are adjacently disposed.

Further, the first electrical signal connector 212 and the second electrical signal connector 2212 are both PIN PINs in the embodiment, however, the first electrical signal connector 212 and the second electrical signal connector 2212 are not limited to PIN PINs, and may be made of various materials and structures capable of achieving electrical connection and electrical signal transmission.

The first electrical signal connector 212 and the second electrical signal connector 2212 may also be one of contact points and the other PIN. For example, the first electrical signal connector 212 is a contact point and the second electrical signal connector 2212 is a PIN. Alternatively, the first electrical signal connector may be a PIN and the second electrical signal connector may be a contact. Or the first electrical signal and the second electrical signal may be both PIN PINs. The first electrical signal connector and the second electrical signal connector are connected in a matched mode.

In one embodiment, the first electrical signal connector and/or the second electrical signal connector are PIN PINs, wherein the PIN PINs include a power PIN and a ground PIN, the power PIN is used for supplying power to the ultrasonic imaging device by a power supply device, and the ground PIN is used for grounding during connection between the power supply device and the ultrasonic imaging device, so as to protect the ultrasonic imaging device.

In one embodiment, on the basis of the above embodiment, the PIN may further include a signal PIN, where the signal PIN may include a communication PIN, and/or a detection PIN, where the communication PIN is used for data transmission between the power supply device and the ultrasonic imaging apparatus, and the detection PIN is used for detecting whether contact is made between the power supply device and the ultrasonic imaging apparatus.

In one embodiment, on the basis of the above embodiment, the grounding PIN is arranged on the periphery of the power supply PIN, and the height of the grounding PIN is higher than that of the power supply PIN. The periphery of the power supply PIN needle is the position surrounding the power supply PIN needle, the grounding PIN needle is arranged surrounding the power supply PIN needle, and the number of the grounding PIN needles can be one, two or more. The periphery of power PIN needle is located to ground connection PIN needle and the height that highly is higher than power PIN needle of ground connection PIN needle for power supply unit's line side interface and ultrasonic imaging equipment's host computer interface can keep ground connection PIN needle to contact earlier at the in-process of butt joint, can guarantee to ground earlier at the butt joint in-process, thereby play the effect of protection ultrasonic imaging equipment.

Referring to fig. 3, 5 and 6, in one embodiment, the first mating surface 2111 has a first protrusion 2112, and the first electrical signal connector 212 is disposed on the first protrusion 2112. Correspondingly, the second docking surface 2215 has a second recess 2216, and the second electrical signal connector 2212 is disposed on the second recess 2216. The first protrusion 2112 and the second recess 2216 are in concave-convex engagement, such that the first electrical signal connector 212 and the second electrical signal connector 2212 are mated.

Similarly, in one embodiment, the first mating surface has a third recess, and the first electrical signal connector is disposed on the third recess. Correspondingly, the second pair of interfaces has a fourth protruding portion, and the second electrical signal connector is disposed on the fourth protruding portion. The third concave part and the fourth convex part are connected in a matched mode, and the first electric signal connecting piece and the second electric signal connecting piece are in butt joint.

The first electric signal and the second electric signal are mutually contacted through the structural design of mutual matching of the convex and the concave, the positioning and guiding effects on the first electric signal and the second electric signal in the butt joint process can be achieved, and the use of an operator is facilitated.

magnetic members

2213 and 2214 are disposed at the sides of the second recess 2216.

Further, referring to fig. 2, in one embodiment, the housing 100 has a socket mounting opening 110, and the first electrical signal connector 212 is located in the socket mounting opening 110. The outermost end of the first electrical signal connector 212 is located inside the edge of the receptacle mounting opening 110 or is flush with the edge of the receptacle mounting opening 110, i.e., the outermost end of the first electrical signal connector 212 is lower than or flush with the edge of the receptacle mounting opening 110 in an outward direction. When the magnet plug 220 is placed at a peripheral position of the socket mounting opening 110, the magnet plug can slide freely along a peripheral region of the socket mounting opening 110 into the socket mounting opening 110 under the attraction of the magnetic member. The outermost end of the first electrical signal connector 212 is located inside the edge of the socket opening 110 or flush with the edge of the socket opening 110, so that the problem that the sidewall of the magnetic socket 210 is abutted against the first electrical signal connector 212 and cannot move into the socket opening 110 due to the fact that the first electrical signal connector 212 protrudes out of the outer wall of the socket opening 110 can be solved. Preferably, the outermost end of the first electrical signal connector 212 is lower than the edge of the socket opening 110, so that a larger space is reserved for the magnetically attractive plug 220 to move more easily into the socket opening 110.

Similarly, referring to fig. 4, in one embodiment, the first mating end 221 of the magnetically attractive plug further includes a plug mounting opening 2217, the second electrical signal connector 2212 is located in the plug mounting opening 2217, and an outermost end of the second electrical signal connector 2212 is located inside of an edge of the plug mounting opening 2217 or is flush with the edge of the plug mounting opening 2217, i.e., the outermost end of the second electrical signal connector 2212 is lower than or flush with the edge of the plug mounting opening 2217 in an outward direction. When the magnetically attractive plug 220 is placed at the peripheral position of the socket mounting opening 110, the magnetically attractive plug can slide freely along the peripheral area of the socket mounting opening 110 into the socket mounting opening 110 under the attraction of the magnetic members, and the outermost end of the second electrical signal connector 2212 is positioned at the same level as the edge of the inner fire-rain plug mounting opening 2217 at the edge of the plug mounting opening 2212, so that a larger space can be reserved for the magnetically attractive plug 220 to move more easily into the socket mounting opening 110.

During the process of docking the magnetic plug and the magnetic socket, the outermost end of the first electrical signal connector 212 of the magnetic socket may be located inside the edge of the socket mounting opening 110 or flush with the edge of the socket mounting opening 110; or the outermost end of the second electrical signal connector of the magnetic plug may be located inside the edge of the plug mounting opening 2217 or flush with the edge of the plug mounting opening 2217; alternatively, the outermost end of the first electrical signal connector 212 of the socket is positioned inside the edge of the socket mounting opening 110 or flush with the edge of the socket mounting opening 110, and the outermost end of the second electrical signal connector of the plug is positioned inside the edge of the plug mounting opening 2217 or flush with the edge of the plug mounting opening 2217.

Further, in the present embodiment, the first magnetic member 213, the second magnetic member 214, the third magnetic member 2213, and the fourth magnetic member 2214 are all magnets. In fact, the first magnetic member 213, the second magnetic member 214, the third magnetic member 2213 and the fourth magnetic member 2214 may also adopt other structures capable of generating magnetism, such as electromagnets. Although the more common magnetic member is a magnet, based on factors such as a use scene, a functional requirement, an assembly space and the like, other structures can be flexibly selected as the corresponding magnetic member according to actual requirements.

Although the present embodiment is specifically described with reference to a portable ultrasound device as an example, the electrical signal docking structure 200 and the mounting structure between the electrical signal docking structure and other components, such as the socket mounting opening 110 of the housing 100, may also be applied to other medical devices and non-medical devices.

The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
