Technical Field

The application relates to medical ultrasonic equipment, in particular to an electrical plug-in structure of the medical ultrasonic equipment.

Background

Medical ultrasonic equipment is a medical instrument developed according to the principle of ultrasonic waves and applied to the field of medical health and used for diagnosing and treating diseases. In the field of medical ultrasound devices, electrical connections are the critical structure for the transfer of power and signals, which are typically achieved by a plug-in fit with a corresponding socket. Where the plug and receptacle are stationary relative to the respective mounting base, for example, in some embodiments the receptacle is provided on the display device and the plug is provided on the host. Due to manufacturing tolerance and other reasons, the plug and socket positions cannot be strictly aligned, so that the plugging process is difficult, and after the plug and socket are installed, once vibration impact and the like exist on any side of the display device or the host, left and right displacement can be generated, so that the left and right displacement is limited, the stress of a matching structure of the plug and the socket is too large, and further the structure is damaged.

The present embodiment provides a medical ultrasonic apparatus, which is a type of medical instrument that can diagnose and treat diseases according to the principle of ultrasonic waves. Specifically, the present embodiment provides an electrical plug structure applied to the medical ultrasound apparatus, so as to realize electrical connection of each component of the medical ultrasound apparatus, so as to transmit but not limited to video, power, electric power, control and other electrical signals.

Referring to fig. 1-4, in one embodiment, the electrical plug structure includes a first member 1 and a second member 2. Wherein, the first component 1 and the second component 2 are two functional components that need to be electrically connected, for example, the first component 1 and the second component 2 may be any one of a display device, an ultrasound host and a control panel, respectively, as in fig. 1 and 2, the first component 1 is a display device, and the second component 2 is a host. Of course, in other embodiments, the first component 1 and the second component 2 may also be other components in the ultrasound apparatus, and are not limited to the display device, the ultrasound host, and the control panel.

Referring to fig. 1-3 and 9-11, the first component 1 has a first base 11 and a first electrical interface 12. The first electrical docking end 12 has a first electrical connection portion 121 for making an electrical connection. The first electrical docking terminal 12 has a first fitting portion 122, and the first fitting portion 122 is coupled to the first base 11. Referring to fig. 1-8, the second member 2 has a second base 21 and a second electrical interface 22. The second electrical connection end 22 has a second electrical connection portion 221, and the first electrical connection portion 121 and the second electrical connection portion 221 are inserted and matched to realize electrical connection. The second electrical docking terminal 22 has a second mounting portion 222, and the second mounting portion 222 is attached to the second base 21.

The first electrical connection portion 121 and the second electrical connection portion 221 may be configured to be electrically connected by plugging, for example, a commonly used male terminal and a female terminal. In one embodiment, the second electrical interface 22 is a socket, the first electrical interface 12 is a plug; alternatively, the second electrical interface 22 is a plug and the first electrical interface 12 is a socket.

Wherein the first base 11 and the second base 21 serve as a mounting base for the first electrical docking terminal 12 and the second electrical docking terminal 22, respectively, for example, in some embodiments, the first base 11 and the second base 21 may be a housing of the first component 1 and the second component 2 or a bracket or a sub-housing fixed with the housing, etc. to provide a support for the first electrical docking terminal 12 and the second electrical docking terminal 22.

Referring to fig. 3-5, in an embodiment, the first electrical connection terminal 12 specifically includes a first circuit board 123, and the first electrical connection portion 121 is fixedly disposed on the first circuit board 123, integrally moves with the first circuit board 123, and is connected to the first base 11. The second electrical interface 22 specifically includes a second circuit board 223, and the second electrical connection portion 221 is fixedly disposed on the second circuit board 223, moves integrally with the second circuit board 223, and is connected to the second base 21. The first mounting portion 122 and the second mounting portion 222 may be, but are not limited to, a part of the boards of the first circuit board 123 and the second circuit board 223, or may be fixed to the first circuit board 123 and the second circuit board 223.

In order to make the first electrical docking end 12 and the second electrical docking end 22 move on the first base 11 and the second base 21 respectively, in an embodiment, at least when the first electrical connection portion 121 and the second electrical connection portion 221 are plugged and mated, a moving space is left between the second assembling portion 222 and the second base 21 and between the first assembling portion 122 and the first base 11, and the second assembling portion 222 and the first assembling portion 122 can move in the moving space, which is a short-distance floating change, so as not to affect the electrical connection effect. This movement may be accomplished by, but is not limited to, material deformation, positional movement, etc., so that the first electrical docking end 12 and the second electrical docking end 22 can be ganged. Before the first electrical docking end 12 and the second electrical docking end 22 are plugged, a movable space may or may not be left between the second assembly portion 222 and the second base 21 and between the first assembly portion 122 and the first base 11, and only when the first electrical connection portion 121 and the second electrical connection portion 221 are plugged, the movable spaces are left between the second assembly portion 222 and the second base 21 and between the first assembly portion 122 and the first base 11.

For the scheme that first electric butt joint end 12 and second electric butt joint end 22 all lock up to and one of them activity setting, the dead unilateral scheme of floating of another lock in the two, vibration impact can be cleared up to this kind of grafting structure that can link, avoids leading to the damage and the connection effect of spare part to be destroyed because of vibration impact, prevents to appear the problem that electrical connection became invalid.

In view of the greater impact of vibration between the first electrical docking terminal 12 and the second electrical docking terminal 22 in a direction perpendicular to the plugging direction, in one embodiment, the movement of the first electrical docking terminal 12 and the second electrical docking terminal 22 includes at least movement in a plugging direction (up and down direction shown in fig. 6 and 7) perpendicular to the first electrical docking terminal 12 and the second electrical docking terminal 22, so that a certain floating displacement can be generated in the direction perpendicular to the plugging direction. This design also reduces manufacturing and assembly requirements for the first electrical docking end 12 and the second electrical docking end 22 in a direction perpendicular to the plugging direction (including the left-right direction shown in fig. 6-8 and the direction perpendicular to the plane of the drawing), for example, the second electrical docking end 22 or the first electrical docking end 12 may be slightly wider or narrower, and the docking may be accomplished by changing the position of the second electrical docking end 22 and/or the first electrical docking end 12.

Further, in one embodiment, the second fitting portion 222 is movably mounted on the second base 21 in the plugging direction. The movement track of the second assembling portion 222 has an inserting section and a section to be inserted, and when the second assembling portion 222 is located at the section to be inserted (i.e., the movement track of the second assembling portion 222 before inserting and matching, such as the one shown in fig. 6 and 7), the second assembling portion 222 is fixed in the direction perpendicular to the inserting direction, and at this time, there is no moving space between the second assembling portion 222 and the second base 21, so that it can be ensured that the second electrical connection portion 221 is located at an accurate position, and it is more convenient for the second electrical connection portion 221 to align with the first electrical connection portion 121. When the second assembling portion 222 is located at the inserting section (as shown in fig. 8), the second electrical connecting portion 221 is inserted into the first electrical connecting portion 121, and a movable space is formed between the second assembling portion 222 and the second base 21.

In order to better facilitate the alignment of the first electrical connection portion 121 and the second electrical connection portion 221, in an embodiment, before the first electrical connection portion 121 is inserted into the second electrical connection portion 221, the second assembling portion 222 is kept at the section to be inserted, that is, the second assembling portion 222 does not shift in a direction perpendicular to the inserting direction, the positions are kept consistent, stable position information of the second electrical connection portion 221 is shown to a user, and the user can insert the first electrical connection portion 121 accurately.

The plugging section of the second assembling portion 222 starts from the first electrical connection portion 121 applying a plugging force along the plugging direction to the second electrical connection portion 221, and under the plugging force, the second electrical connection portion 221 is driven to drive the second assembling portion 222 to move along the plugging direction (for example, the up-down direction in the embodiment shown in fig. 6-8) until the first electrical connection portion 121 and the second electrical connection portion 221 complete the plugging and mating. The position of the second mounting portion 222 changes such that a movable space is formed between the second mounting portion 222 and the second base 21, and the movable space can allow the second mounting portion 222 to have a certain floating change space relative to the second base 21 to accommodate the floating change of the first electrical docking terminal 12.

In one embodiment, when the second assembling portion 222 is located at the inserting section, the first electrical docking end 12 is located at the upper side of the second electrical docking end 22, and the second assembling portion 222 is maintained at the inserting section (as shown in fig. 8) by the gravity of the first component 1 (such as a display device), so that the second assembling portion 222 is maintained at the floatable state.

In other embodiments, at least one of the first electrical docking terminal 12 and the second electrical docking terminal 22 has a detachable connection. When the second assembling portion 222 is located at the plugging section, the first electrical docking terminal 12 and the second electrical docking terminal 22 are detachably fixed by the detachable connection portion, so that the second assembling portion 222 is maintained at the plugging section, and the second assembling portion 222 is maintained in a floatable state.

In one embodiment, the releasable attachment may be at least one of, but not limited to, a snap fit, a releasable adhesive, a magnetic attraction connection, a threaded connection, and an interference fit connection.

The detachable connection structure can be unlocked manually by a user, for example, by a physical structure such as a button, a lever, a dial, a pull cord, or a touch unit such as a touch key or a touch screen, so as to detach the plug-in connection between the first electrical docking end 12 and the second electrical docking end 22. The detachable connection structure may also be unlocked automatically by the device, for example, when the device determines that the first electrical docking end 12 and the second electrical docking end 22 need to be undone, the detachable connection structure is controlled to unlock.

Referring to fig. 5-8, in a more specific embodiment, to enable the second mounting portion 222 to move between the non-plug section and the plug section, the second base 21 has a second mating portion 211. The second fitting portion 211 has a wide portion 2111 provided in the plugging direction and a narrow portion 2112 having an outer diameter narrower than the wide portion 2111. The second fitting portion 222 has a cavity through which the second fitting portion 211 passes. The second fitting portion 222 and the second mating portion 211 are relatively movable in the plugging direction. As shown in fig. 6 and 7, when the second assembling portion 222 is located at the segment to be plugged, the inner wall of the cavity of the second assembling portion 222 abuts against the wide portion 2111, so as to limit the movement of the second assembling portion 222 along the direction perpendicular to the plugging direction, and at this time, the second electrical docking end 22 is fixed in position in the direction perpendicular to the plugging direction, so as to facilitate the alignment of the first electrical docking end 12. When the first electrical connection portion 121 applies a plugging force to the second electrical connection portion 221 and the second mounting portion 222 is located at the plugging section after the first electrical docking end 12 is plugged in, as shown in fig. 8, the second mounting portion 222 begins to separate from the wide portion 2111 and moves downward as shown, forming a moving space with the narrow portion 2112. The inner diameter of the cavity at least at the portion corresponding to the narrow portion 2112 (the inner diameter of the entire cavity may be) is larger than the outer diameter of the narrow portion 2112, so that the above-mentioned movable space can be formed.

Further, in one embodiment, the wide portion 2111 has a tapered outer wall 2113 (conical or pyramidal) with the thinner end of the tapered outer wall 2113 connected to the narrow portion 2112, forming a tapered configuration with a larger top and a smaller bottom as shown in FIGS. 5-8. The cavity of the second fitting portion 222 has a tapered inner cavity wall 2221 matching the tapered outer wall 2113, and the tapered inner cavity wall 2221 is also large in top and small in bottom. When the second assembling portion 222 is located at the segment to be plugged, the tapered inner cavity wall 2221 abuts against the tapered outer wall 2113, and the second assembling portion 222 is limited from moving in a direction perpendicular to the plugging direction. When the second fitting portion 222 is located at the plug section, the tapered inner cavity wall 2221 is separated from the tapered outer wall 2113, and forms at least a part of the movable space with the narrow portion 2112. The tapered inner chamber wall 2221 may also abut against a mating chamber 2222 at an end (shown below) proximate the narrow portion 2112. the mating chamber 2222 may be, but is not limited to, a cylindrical chamber. Of course, the mating cavity 2222 may be omitted.

In other embodiments, the tapered outer wall 2113 and the tapered inner cavity wall 2221 may be replaced with other shapes, such as spherical outer wall and spherical inner cavity wall, stepped outer wall and stepped inner cavity wall, etc. When the second assembling portion 222 is reset to the segment to be plugged, the tapered outer wall 2113 and the spherical outer wall can play a good guiding role, so that the second assembling portion 222 is quickly reset to a correct position.

Referring to fig. 5-8, in an embodiment, the second matching portion 211 is a supporting pillar fixed on a portion of the second base 21. The second assembling portion 222 is a sleeve, and the sleeve is sleeved on the supporting column. Of course, other plug-in structures can be selected for the second mating portion 211 and the second mounting portion 222, besides the illustrated structures.

For example, in an embodiment (not shown in the figures), the second base 21 has a second mating portion 211, which second mating portion 211, in turn, has a cavity arranged in the plugging direction. The cavity has a second cavity portion and a first cavity portion having a narrower inner diameter than the second cavity portion. The second fitting portion 222 has a wide portion shaped to match the inner cavity wall of the second cavity portion and a narrow portion having an outer diameter smaller than the wide portion. The wide portion is disposed within the second cavity portion and the narrow portion passes through the second cavity portion and the first cavity portion. The second fitting portion 222 and the second fitting portion 211 are relatively movable in the plugging direction. When the second assembling portion 222 is located at the section to be plugged, the outer wall of the wide portion is attached to the inner wall of the second cavity portion, so that the second assembling portion 222 is limited to move in the direction perpendicular to the plugging direction. When the second fitting portion 222 is located at the plug section, the wide portion is separated from the narrow portion, and at least a part of the movable space is formed between the narrow portion and the second cavity portion and the first cavity portion. The structure is similar to the reverse arrangement of the second matching part 211 and the second assembling part 222 shown in fig. 5-8, i.e. the second matching part 211 is a cavity structure and the second assembling part 222 is a column structure.

Likewise, for a more accurate and rapid return of the second fitting portion 222, the wide portion may have a tapered outer wall or a spherical outer wall in one embodiment. The thinner end of the conical outer wall or the spherical outer wall is connected with the narrow part. The second chamber part is provided with a conical inner chamber wall matched with the conical outer wall or a spherical inner chamber wall matched with the spherical outer wall. When the second assembling portion 222 is located at the section to be plugged, the tapered inner cavity wall or the spherical inner cavity wall is attached to the corresponding tapered outer wall or spherical outer wall, so that the second assembling portion 222 is limited to move in the direction perpendicular to the plugging direction. When the second assembling portion 222 is located at the inserting section, the tapered inner cavity wall or the spherical inner cavity wall is separated from the corresponding tapered outer wall or spherical outer wall, and the narrow portion forms at least a part of the moving space with the second cavity portion and the first cavity portion. In other embodiments, the tapered outer wall or the spherical outer wall may be replaced by other shapes, such as a stepped outer wall and a stepped inner cavity wall.

On the other hand, after the first electrical docking terminal 12 and the second electrical docking terminal 22 are disconnected, the second electrical docking terminal 22 can be reset to the original non-plugging section for the convenience of the next plugging. For the purpose of resetting, a resetting structure can be designed, and the resetting can be realized manually by a user or automatically by the resetting structure. In the manual reset, the second electrical contact 22 can be manually driven to reset by a user using a shifting block, a pull rope, a shifting lever, or the like. The automatic reset can be realized by resetting elastic elements or electromagnets and other components.

In an embodiment, referring to fig. 6 to 8, the assembly portion further includes a reset elastic element 224 for driving the second assembly portion 222 to reset to the segment to be plugged, and the reset elastic element 224 directly or indirectly acts on the second assembly portion 222 to drive the second assembly portion 222 to reset to the segment to be plugged. The resilient member 224 automatically returns the second mounting portion 222 to the segment to be plugged when the first electrical docking end 12 and the second electrical docking end 22 are disconnected.

The resilient member 224 ensures that the position of the second electrical docking end 22 is unchanged every time the first electrical docking end 12 is inserted, so as to reduce the tolerance between the first electrical docking end 12 and the second electrical docking end 22 caused by the position change of the second electrical docking end 22 in the horizontal direction (left and right directions shown in fig. 5-8), and reduce the design requirement for the floating amount of the first electrical docking end 12 in the situation of tight space, thereby reducing the design difficulty and increasing the reliability of guiding. Moreover, when the second electrical docking end 22 appears on the outer surface of the product, the second electrical docking end 22 can be kept at the outermost position under the action of the elastic restoring member 224, and has an accurate and unique initial position, so that looseness and uneven gaps are avoided, and the neatness of the product is improved. In addition, the design of the elastic reset piece 224 is also beneficial to improving the stability when the first electrical docking end 12 and the second electrical docking end 22 are connected, especially under the condition of vibration impact, the second electrical docking end 22 can keep tight docking with the first electrical docking end 12 under the action of the elastic reset piece 224, the first electrical docking end 12 and the second electrical docking end 22 are prevented from being loosened and connected electrically due to the vibration impact, and the connection reliability is continuously kept in the plugging direction.

Referring to fig. 5-8, in a more specific embodiment, the elastic restoring member 224 is disposed on the second matching portion 211, and one end thereof is connected to the bottom of the second assembling portion 222, and the connection manner may be abutting connection or fixed connection to the bottom of the second assembling portion 222. The other end of the elastic restoring member 224 is connected to the supporting member 212, as shown in fig. 5-8, such connection may be that the elastic restoring member 224 is mounted on the supporting column (i.e. the second matching portion 211) through the supporting member 212 and the screw 213, and besides, the elastic restoring member 224 may also be mounted through welding, bonding, interference fit, or other methods. The supporting member 224 is located at an end of the narrow portion 2112 of the second matching portion 211 away from the wide portion 2111, and the supporting member 224 can be fixedly connected with the second matching portion 211 or can be detachably connected with the second matching portion.

The restoring elastic member 224 may be disposed at other positions, for example, an outer side of the second fitting portion 211, etc., by pushing the restoring of the second fitting portion 222 through the above-described connection manner.

The return elastic member 224 is a compression spring, and in other embodiments, an extension spring, a spring plate, a torsion spring, or other elastic members may be used instead. The elastic restoring member may be a tension spring, and in the case that the elastic restoring member is a tension spring, the second engaging portion 211 and the second assembling portion 222 need to be adaptively adjusted.

The elastic resetting piece can also be a tension spring, and under the condition that the elastic resetting piece is the tension spring, the second matching part and the second assembling part need to be adjusted adaptively.

Alternatively, the first electrical interface terminal 12 may have the same or similar structure as the second electrical interface terminal 22 described above. Of course, the first electrical docking end 12 may have different configurations to achieve the linkage with the second electrical docking end 22.

In one embodiment, the first base 11 has a first mating portion, the first assembling portion 122 is in plug-in mating with the first mating portion, and a gap is left between the first assembling portion 122 and the first mating portion in the plug-in direction and the direction perpendicular to the plug-in direction to form a moving space.

For example, referring to fig. 9 to 11, in an embodiment, the first assembling portion 122 has an assembling hole 1221, the first matching portion has a fixing base 112 and a screw 111, the screw 111 passes through the assembling hole 1221 and is installed on the fixing base 112, a gap is left between an outer circumferential wall of the screw 111 and the assembling hole 1221, and a gap is left between a head of the screw 111 and the fixing base 112, so that the first assembling portion 122 and the entire first electrical docking end 12 can move in the plugging direction and the direction perpendicular to the plugging direction.

More specifically, in one embodiment, referring to fig. 9-11, the screw member 111 has a screw connection portion, a step portion with an outer diameter larger than the screw connection portion, and a head portion with an outer diameter larger than the step portion. The screw-connection part is fixed on the fixing base 112 in a screw-connection manner, and the step part is arranged at the outer end of the fixing base 112. A stitching space 113 is defined between the fixing seat 112 and the head, and the first assembling portion 122 is sleeved on the step portion and can move towards the side where the head is located and the side where the fixing seat 112 is located in the stitching space 113. That is, the height of the stitching space 113 is greater than the thickness of the first mounting portion 122 (e.g., the thickness of the board card), so that the first mounting portion 122 can move (move up and down as shown) within the stitching space 113. The design of this step part forms the assembly spacing for screw member 111 is simpler when installing, and the assembler need not consider the screw-in degree of depth of screw member 111 too much.

In order to achieve a more stable insertion, referring to fig. 4 to 8, the first assembling portion 122 and the second assembling portion 222 are two or more and are distributed on two sides of the corresponding first electrical connection portion 121 and the second electrical connection portion 221.

Further, in consideration of the insertion environment of the first electrical docking end 12 and the second electrical docking end 22, the docking condition of the first electrical docking end 12 and the second electrical docking end 22 cannot be directly observed in many cases, and therefore, in some embodiments, the first electrical docking end 12 and the second electrical docking end 22 are provided with a guiding structure.

In one embodiment, the first electrical docking end 12 has a first position-limiting guide portion 124, the second electrical docking end 22 has a second position-limiting guide portion 225, and the second position-limiting guide portion 225 and the first position-limiting guide portion 124 are oppositely disposed to guide the second electrical connection portion 221 and the first electrical connection portion 121 to be docked in the correct position.

Referring to fig. 6 and 7, in one embodiment, one of the first limit guide part 124 and the second limit guide part 225 is a guide hole, and the other is a guide post, the guide hole has a guide opening with a large outside and a small inside and/or the guide post has a guide end 1241 with a narrow front and a wide back.

Further, the number of the second limiting guiding parts 225 is at least two, and the second limiting guiding parts are distributed on two sides of the second electrical connection part 221; the number of the first limiting guide portions 124 is at least two, and the first limiting guide portions are distributed on two sides of the first electrical connection portion 121. By such a design, the first limit guide part 124 and the second limit guide part 225 can guide the first electrical connection part 121 and the second electrical connection part 221 which are positioned in the middle to be correctly plugged.

Referring to fig. 6-8, in one embodiment, the plugging process of the first electrical interface terminal 12 and the second electrical interface terminal 22 can be briefly described as follows:

due to the influence of manufacturing tolerances, mounting tolerances, and the like, the central axis of the first limit guide 124 and the central axis of the second limit guide 225 often do not coincide on the insertion end surfaces of the first electrical connection portion 121 and the second electrical connection portion 221. In order to ensure that the first limit guide part 124 and the second limit guide part 225 can be coaxial with each other in the central axis direction after installation, a rear guide end 1241 is provided at the head of the first limit guide part 124. During installation, as shown in fig. 6 and 7, as the first electrical docking end 12 moves downward, the guide end 1241 enters the second limit guide 225, and under the action of the guide end 1241, the central axis of the first limit guide 124 can move left and right, so as to gradually coincide with the central axis of the second limit guide 225, as shown in fig. 7.

As the installation process continues, after the central axis of the first limit guide 124 and the central axis of the second limit guide 225 tend to coincide, the first electrical docking terminal 12 and the second electrical docking terminal 22 start to mate, and the plugging action is completed. At this time, under the pushing of the second electrical docking end 22, the first electrical docking end 12 pushes the return elastic member 224 to move downward, so that the tapered outer wall 2113 is disengaged from the tapered inner cavity wall, as shown in fig. 8, to form a movable space. When the first electrical docking end 12 floats in the left-right direction, the second electrical docking end 22 can move left and right along with the first electrical docking end, so that the following movement is realized.

After the plugging and mating, since the elastic restoring member 224 is compressed by a certain amount, a continuous upward force is applied to the second electrical contact 22, and after the vibration impact in the vertical direction occurs, the elastic force changes accordingly and provides continuous support, and continuous compression is provided, thereby increasing the reliability of the connection.

When the first electrical docking terminal 12 is removed, the first electrical docking terminal 12 moves upward and away from the second electrical docking terminal 22 to come into contact with the second electrical docking terminal 22. The second electrical contact terminal 22 moves upward under the pushing force of the resilient member 224, and the tapered outer wall 2113 engages with the tapered inner cavity wall, so that the position of the second electrical contact terminal 22 after being reset can accurately return to the initial position.

On the other hand, the present embodiment further provides an ultrasound apparatus, which includes a display device, an ultrasound host, and a control panel, wherein at least two components of the display device, the ultrasound host, and the control panel are provided with an electrical plug structure as in any of the above embodiments.
