[0002] Ultrasonic testing is a common auxiliary diagnostic method, primarily performed using an ultrasound system. An ultrasound system typically consists of a main unit and an external device (such as a trolley) that powers the main unit. In related technologies, during installation, the main unit and external device are often connected via a cable to enable signal transmission between them. However, this method requires cable alignment and plugging during installation, which is cumbersome. Furthermore, the cable can easily become loose after installation, leading to connection failure.

[0014] In one embodiment, the first connecting terminal includes a plurality of first contacts, and the second connecting terminal includes a plurality of spring pins corresponding to the plurality of first contacts, wherein the spring pins are capable of elastically abutting against the corresponding first contacts;

[0015] And / or, the first connection terminal includes a plurality of first contacts, and the plurality of first contacts are symmetrically distributed about the center of the first connector.

[0016] In one embodiment, the spring pin includes a short pin whose length is shorter than that of the other spring pins.

[0041] See Figures 1 to 4 An embodiment of the present application provides a docking structure for an ultrasound system, comprising a first connector 100 and a second connector 200. The first connector 100 comprises a first connection terminal 110 and a first annular magnetic member 120, wherein the first annular magnetic member 120 is disposed around the outside of the first connection terminal 110. The second connector 200 comprises a second connection terminal 210 and a second annular adsorption member 220, wherein the second annular adsorption member 220 is disposed around the outside of the second connection terminal 210. The first connection terminal 110 and the second connection terminal 210 are aligned and contacted under the magnetic force of the first annular magnetic member 120 and the second annular adsorption member 220.

[0042] One of the first connector 100 and the second connector 200 is used to connect to the host 300 of the ultrasound system, and the other is used to connect to an external device of the ultrasound system.

[0043] In the docking structure for the ultrasound system, the first annular magnetic part 120 and the second annular adsorption part 220 can interact with each other through magnetic force, so that the first connection terminal 110 and the second connection terminal 210 are aligned and contacted under the magnetic force of the first annular magnetic part 120 and the second annular adsorption part 220, so as to realize the electrical connection between the host 300 and the external device. During the above connection process, it is only necessary to bring the first connector 100 and the second connector 200 close to each other, so that the first connection terminal 110 and the second connection terminal 210 can be automatically aligned and contacted by magnetic force, without the need for the operator to carefully align, which can simplify the operation. In addition, since the two connectors are physically connected through the magnetic force of the first annular magnetic part 120 and the second annular adsorption part 220, under the same installation space requirements, the annular magnet has higher production and assembly efficiency than a single split magnet, and has stronger magnetic force, which can improve the firmness and contact reliability of the two connectors after connection, and is less likely to cause connection failure.

[0044] See Figure 3 In some embodiments, the first annular magnetic member 120 may be a permanent magnet, or an electromagnet.

[0045] See Figure 3 In some embodiments, the second annular adsorption member 220 can be a magnetic member (permanent magnet or electromagnet) that also has magnetic force, or a metal member that does not have magnetic force but can be attracted by a magnetic member. In the following embodiments, the second annular adsorption member 220 is described as a magnetic member.

[0046] See Figures 6 and 7 In some embodiments, the first annular magnetic member 120 has a docking surface for contacting the second annular adsorption member 220 , and the docking surfaces have the same magnetic properties.

[0047] Specifically, the docking surface on the first annular magnetic member 120 is located at one end close to the second annular adsorption member 220 along the docking direction. The docking direction is the arrangement direction of the first annular magnetic member 120 and the second annular adsorption member 220 ( Figure 6 and Figure 7 (direction perpendicular to the paper surface under viewing angle).

[0048] See Figures 6 and 7 In some embodiments, the first annular magnetic member 120 includes an integrated magnetic portion or multiple groups of magnetic portions arranged in an annular manner, wherein the N pole and the S pole are respectively provided at both ends of the first annular magnetic member 120 along the docking direction.

[0049] Specifically, when the first annular magnetic member 120 includes an integrated magnetic portion, if its mating surface is an N pole, then the end facing away from the mating surface along the mating direction is an S pole. Correspondingly, the end of the second annular adsorbent 220 that is closer to the first annular magnetic member 120 along the mating direction is an S pole, and the end facing away from the first annular magnetic member 120 along the mating direction is an N pole.

[0050] When the first annular magnetic part 120 includes multiple groups of magnetic parts arranged in an annular pattern, the N pole and S pole of each group of magnetic parts are located at both ends of the first annular magnetic part 120 along the docking direction, and the magnetism of each group of magnetic parts at the docking surface is the same. Correspondingly, the second annular adsorption part 220 is provided with multiple groups of adsorption parts, and the N pole and S pole of each group of adsorption parts are also located at both ends of the first annular magnetic part 120 along the docking direction, and the N pole of the adsorption part corresponds to the S pole of the magnetic part, and the S pole of the adsorption part corresponds to the N pole of the magnetic part, so as to achieve mutual attraction. By providing multiple groups of magnetic parts and adsorption parts, the magnetic attraction force can be further enhanced, and the firmness and contact reliability of the two connectors after connection can be improved.

[0051] Preferably, the multiple groups of magnetic parts on the first annular magnetic part 120 are arranged in an annular pattern at intervals, and correspondingly, the multiple groups of adsorption parts on the second annular adsorption part 220 are also arranged in an annular pattern at even intervals, so as to improve the uniformity of the magnetic attraction force in each area after connection, thereby further improving the firmness and contact reliability after connection.

[0052] In the embodiment shown in the accompanying drawings, the first annular magnetic member 120 includes four sets of magnetic portions arranged in a circular pattern, and the second annular adsorbing member 220 includes four sets of adsorbing portions arranged in a circular pattern. Any two adjacent sets of magnetic portions / adsorbing portions are spaced 90 degrees apart. In other embodiments, the number of magnetic portions and adsorbing portions may be three, five, six, or other numbers.

[0053] See Figures 3 to 5 In some embodiments, the first annular magnetic member 120 has a docking surface for contacting the second annular adsorption member 220 , and the magnetic properties of the docking surfaces are different.

[0054] Specifically, the different magnetism of the mating surface refers to different magnetism in different areas of the mating surface. For example, the magnetism of one area is N, and the magnetism of another area is S.

[0055] See Figures 3 to 5 In some embodiments, the first annular magnetic member 120 includes an integrated magnetic portion, wherein the N pole and the S pole of the magnetic portion are respectively provided at both ends along a first direction, and the first direction is perpendicular to the mating direction of the first connector 100 and the second connector 200;

[0056] Alternatively, the first annular magnetic member 120 includes a plurality of groups of magnetic portions arranged in an annular manner, and in each group of magnetic portions, the N pole and the S pole are respectively provided at both ends of the first annular magnetic member 120 along the docking direction or the first direction.

[0057] Specifically, when the first annular magnetic part 120 includes an integrated magnetic portion, if one end thereof along the first direction is an N pole, the other end along the first direction is an S pole. Correspondingly, the magnetism of the contact position of the second annular adsorbent 220 with the first annular magnetic part 120 is opposite to that of the first annular magnetic part 120, so as to achieve mutual attraction. For example, the N pole and S pole of the second annular adsorbent 220 are also arranged at both ends of itself along the first direction, and the N pole of the second annular adsorbent 220 corresponds to the S pole position of the first annular magnetic part 120, and the S pole of the second annular adsorbent 220 corresponds to the N pole position of the first annular magnetic part 120, so as to achieve mutual attraction. When the first connector 100 and the second connector 200 are close to each other, the areas with opposite magnetism on the second annular adsorbent 220 and the first annular magnetic part 120 attract each other, and the areas with the same magnetism repel each other. Therefore, only when the relative positions of the first connector 100 and the second connector 200 are correct can they be smoothly engaged, thereby preventing incorrect reverse connection and playing a fool-proof role to avoid power supply / communication anomalies.

[0058] exist Figure 4 and Figure 5 In the perspective, the first direction is the left-right direction, and the north pole and south pole of the magnetic portion of the first annular magnetic member 120 are arranged left-right. In other embodiments, the first direction can also be other directions, such as the up-down direction, in which case the north pole and south pole of the magnetic portion of the first annular magnetic member 120 are arranged up-down.

[0059] When the first annular magnetic part 120 includes multiple groups of magnetic parts arranged in an annular manner, and in each group of magnetic parts, the N pole and the S pole are respectively provided at both ends of the first annular magnetic part 120 along the docking direction, it is similar to the case in the aforementioned embodiment where the magnetic properties on the docking surface of the first annular magnetic part 120 are the same, and the first annular magnetic part 120 includes multiple groups of magnetic parts arranged in an annular manner. However, in order to ensure that the magnetic properties on the docking surface are different, the magnetic properties of at least two groups of magnetic parts in the first annular magnetic part 120 are different at the docking surface. For example, the magnetic properties of one group of magnetic parts at the docking surface are N, and the magnetic properties away from the docking surface along the docking direction are S; the magnetic properties of the other group of magnetic parts at the docking surface are S, and the magnetic properties away from the docking surface along the docking direction are N. The second annular adsorption part 220 can be the opposite.

[0060] When the first annular magnetic component 120 includes multiple groups of magnetic parts arranged in a ring, and in each group of magnetic parts, the N pole and the S pole are respectively arranged at both ends of the first annular magnetic component 120 along the first direction, the first direction can be the radial direction of the first annular magnetic component 120, that is, in each group of magnetic parts, the N pole and the S pole are respectively arranged at the outer ring and the inner ring of the first annular magnetic component 120.

[0061] See Figure 3 、 Figure 6 and Figure 7 Furthermore, in some embodiments, the first connection terminal 110 includes a plurality of first contacts 112 , and the plurality of first contacts 112 are symmetrically distributed about the center of the first connector 100 .

[0062] Furthermore, in some embodiments, the first annular magnetic member 120 includes multiple groups of magnetic parts arranged in a ring, each group of magnetic parts has the same magnetism at the mating surface, and the first connecting terminal 110 includes multiple first contacts 112, and the multiple first contacts 112 are symmetrically distributed about the center of the first connector 100.

[0063] Specifically, the end of the first annular magnetic part 120 where the mating surface is located is an S pole, and the end away from the mating surface is an N pole; the end of the second annular adsorption part 220 close to the first annular magnetic part 120 is an N pole, and the end away from the first annular magnetic part 120 is an S pole. In the embodiment of the accompanying drawings, the first connecting terminal 110 includes two upper and lower rows of first contacts 112. These two rows of first contacts 112 include various types, for example, at least including contacts for signal conduction and contacts for transmitting current. It is necessary to contact the corresponding positions of each type of first contact 112 with the second connecting terminal 210 to achieve conduction. Since the magnetic properties of each group of magnetic parts are the same at the mating surface, incorrect reverse connection may occur. However, the central symmetrical distribution of multiple first contacts 112 can avoid the above problem and ensure that the two connectors can still be normally connected and conductive after rotating 180 degrees without reverse connection. In this way, it can be ensured that the two connectors can be normally connected regardless of whether they are rotated 180 degrees, further simplifying the operation process.

[0064] See Figures 1 to 3 In some embodiments, the first connection terminal 110 includes a plurality of first contacts 112 ; the second connection terminal 210 includes a plurality of spring pins 211 corresponding one-to-one to the plurality of first contacts 112 , and the spring pins 211 can elastically abut against the corresponding first contacts 112 .

[0065] Specifically, the first connection terminal 110 includes a connection plate 111, with a plurality of first contacts 112 disposed on the connection plate 111. Multiple spring pins 211 are capable of elastically expanding and contracting along the mating direction. When the two connectors approach each other, the spring pins 211 are squeezed by the connection plate 111, elastically retracting to a certain extent and ultimately elastically abutting against corresponding first contacts 112 on the connection plate 111. Because no plug-in or pull-out mechanism is provided during the mating process, contact is achieved directly through the spring pins 211 abutting against corresponding areas on the connection plate 111, thus avoiding structural damage and connection failure caused by improper plug-in or pull-out directions.

[0066] See Figure 5 and Figure 7 Preferably, in some embodiments, among the first contacts 112 on the first connection terminal 110, the first contact 112 for transmitting high-power current generates higher heat, and therefore, it is arranged in the outer area to dissipate heat to the external environment to improve heat dissipation efficiency.

[0067] See Figure 3 and Figure 8 In some embodiments, among the multiple elastic pins 211, some of the elastic pins 211 are short pins with a length shorter than that of other elastic pins 211. When the short pins are connected to the corresponding first contacts 112, the docking structure is turned on; when the short pins are separated from the corresponding first contacts 112, the docking structure is disconnected.

[0068] Specifically, at least one of the multiple spring pins 211 is a short pin. The docking structure includes an electrically connected detection circuit 410 and a power control circuit 420, both of which are electrically connected to the second connection terminal 210. The detection circuit 410 can detect the on / off state between the short pin and the corresponding first contact 112; the power control circuit 420 can control the on / off state of the second connection terminal 210 based on the on / off state, thereby achieving the connection and disconnection of the docking structure.

[0069] Furthermore, the detection circuit 410 and the power control circuit 420 are arranged on the external device side. The external device side is also provided with an electrically connected power circuit 430 and a power adapter 440, and the power adapter 440 can supply power to the power circuit 430; the power control circuit 420 is electrically connected to the power circuit 430, and the power control circuit 420 can control the on and off of the power circuit 430. The power control circuit 420 can control the on and off of the power circuit 430 based on the on-off state between the short pin and the corresponding first contact 112 measured by the detection circuit 410, thereby controlling the on and off of the second connection terminal 210, and realizing the conduction and disconnection of the docking structure. For example, if the power control circuit 420 controls the power circuit 430 to be powered on, the second connection terminal 210 is in the powered state and the docking structure is connected; if the power control circuit 420 controls the power circuit 430 to be powered off, the second connection terminal 210 is in the powered state and the docking structure is disconnected.

[0070] Understandably, the short pin is shorter than the other spring pins 211. Therefore, during the docking process, the short pin is inevitably the last to make contact with the corresponding first contact 112, and during the separation process, the short pin is inevitably the first to disconnect from the corresponding first contact 112. During the docking process, when the short pin and the corresponding first contact 112 are in a conductive state, the power circuit 430 is controlled to be powered on. This ensures that power is turned on only after the docking is complete, thereby improving the safety of the docking process and the stability of the electrical connection. During the separation process, when the short pin and the corresponding first contact 112 are disconnected, the power circuit 430 is controlled to be powered off, thereby achieving timely power off and improving the safety of the separation process.

[0071] See Figure 3 and Figure 8 In some embodiments, the docking structure includes a detection portion and an indicator portion electrically connected to the detection portion. The detection portion is capable of detecting the on / off state of the docking structure; and the indicator portion is used to display the on / off state.

[0072] Specifically, the detection unit can be an interactive detection circuit 460 provided on the host 300, or an external detection circuit 410, or both the interactive detection circuit 460 and the detection circuit 410. The indication unit can be an interactive terminal 470 provided on the host 300, or an interactive interface 450 provided on an external device, or both the interactive terminal 470 and the interactive interface 450.

[0073] See Figure 3 and Figure 8 In some embodiments, the docking structure includes an interaction detection circuit 460 electrically connected to the first connection terminal 110, and an interaction terminal 470 electrically connected to the interaction detection circuit 460. The interaction detection circuit 460 can detect the on / off state between the short pin and the corresponding first contact 112; the interaction terminal 470 is used to display the on / off state.

[0074] Specifically, the interactive detection circuit 460 and the interactive terminal 470 are both provided on the host 300 side. Similar to the detection circuit 410, the interactive detection circuit 460 can also detect the on / off state between the short pin and the corresponding first contact 112. The detection result of the interactive detection circuit 460 can be displayed on the interactive terminal 470 to remind the operator whether the host 300 is currently powered.

[0075] Similarly, an interactive interface 450 may also be provided on the external device side. The interactive interface 450 is electrically connected to the detection circuit 410 and can display on the external device side whether the power circuit 430 is currently supplying power.

[0076] See Figure 1 and Figure 8 In some embodiments, the second connector 200 is provided with a status indicator 230 that is communicatively connected to the detection circuit 410 , and the status indicator 230 is used to indicate the on / off status between the short pin and the corresponding first contact 112 .

[0077] Specifically, the status indicator 230 may be an indicator light or an alarm, etc., which can play a similar role as the interactive interface 450 , and display on the external device side whether the current power circuit 430 is supplying power.

[0078] In the aforementioned embodiments, the first connector 100 is used to connect to the host 300, and the second connector 200 is used to connect to the external device. In other embodiments, they can be interchanged, that is, the second connector 200 is used to connect to the host 300, and the first connector 100 is used to connect to the external device.

[0079] See Figures 1 to 3 An ultrasound system provided in one embodiment of the present application includes the docking structure for the ultrasound system in any one of the above embodiments, and also includes a host 300 and an external device, one of the first connector 100 and the second connector 200 is provided on the host 300, and the other is provided on the external device.

[0080] Specifically, in the embodiment shown in the drawings, the first connector 100 is used to connect to the host 300, and the second connector 200 is used to connect to an external device. The external device can be a trolley supported below the host 300. By docking the first connector 100 with the second connector 200, the trolley can provide power to the host 300 and enable signal transmission between the two. Alternatively, the external device can be other devices.

[0081] See Figures 1 to 3 In some embodiments, the first connector 100 includes a connecting pin 140 , one end of the connecting pin 140 is connected to the first connecting terminal 110 , and the other end is connected to the circuit board 130 of the ultrasound system.

[0082] Specifically, the circuit board 130 has a mounting location for a heat sink. One end of the connecting pin 140 is soldered to the first connecting terminal 110, and the other end is soldered to the circuit board 130. As can be understood, when the second connecting terminal 210 and the first connecting terminal 110 are in contact and conductive, heat is generated. The provision of the connecting pin 140 allows this heat to be transferred to the circuit board 130, where it can then be dissipated by the heat sink installed in the mounting location. Installing a heat sink on a circuit board 130 with a more regular shape makes installation much easier.

[0083] There are multiple connecting pins 140 mentioned above, one end of each connecting pin 140 is welded to the corresponding spring pin 211, and the other end is welded to the circuit board 130, so as to conduct the heat from the spring pin 211 to the circuit board 130, and then dissipate the heat through the heat sink installed in the mounting position.
