Taking an ultrasonic detection device as an example, if the grounding effect of each module of the ultrasonic detection device is poor and the electrical signals are unstable, it will seriously interfere with the imaging quality of the pictures.

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] As Figures 1-4 As shown, this embodiment provides a detection device for medical detection. The detection device includes a housing 1, a main board assembly 2, and at least one first conduction member 3. The main board assembly 2 is installed inside the housing 1. The main board assembly 2 includes a main board 21 and an adapter 22. The main board 21 and the adapter 22 are electrically connected, and the main board 21 is grounded. The first conduction member 3 is installed inside the housing 1 and conducts with the housing 1. The main board 21 and the adapter 22 are respectively conducted with the housing 1 through at least one first conduction member 3.

[0037] The detection device provided by the present utility model installs the first conduction member 3 inside the housing 1. The main board 21 and the adapter 22 are respectively conducted with the housing 1 through the first conduction member 3, and then the main board 21 is grounded, so that the main board 21, the adapter 22, and the housing 1 are all grounded, ensuring the stability of the electrical signal during detection, and thus making the detection accuracy higher.

[0038] The detection device in this embodiment is specifically an ultrasonic detection device.

[0039] Further, in order to prevent poor conduction or even virtual connection between the main board 21 and the first conduction member 3, the number of the first conduction members 3 is multiple. The main board 21 is conducted with the housing 1 through multiple first conduction members 3, and adjacent first conduction members 3 are spaced apart.

[0040] Further, the adapter 22 is conducted with the housing 1 through multiple first conduction members 3, and adjacent first conduction members 3 are spaced apart to ensure good conduction between the adapter 22 and the first conduction member 3.

[0041] Of course, it is also possible that only the main board 21 is conducted with the housing 1 through multiple first conduction members 3, or only the adapter 22 is conducted with the housing 1 through multiple first conduction members 3.

[0042] In this embodiment, fifteen first conducting members 3 are provided. The number of the first conducting members 3 in other embodiments may also be set to twenty to ensure good conduction effects between the adapter 22 and the first conducting members 3 and between the main board 21 and the first conducting members 3.

[0043] Furthermore, in some embodiments, a plurality of rib plates 11 are connected to the inner wall of the housing 1 at intervals along its circumferential direction. The plurality of first conducting members 3 are respectively connected to the plurality of rib plates 11, and the plurality of first conducting members 3 are arranged along the length direction of the rib plates 11, so that the installation of the first conducting members 3 is more firm.

[0044] Furthermore, as Figure 5 shown, the detection device further includes a second conducting member 4. The housing 1 includes an upper shell 12 and a lower shell 13 which are detachably installed. The second conducting member 4 is installed on one of the upper shell 12 and the lower shell 13 and abuts against the other one of the upper shell 12 and the lower shell 13 to conduct the upper shell 12 and the lower shell 13, thereby achieving good conduction between the upper shell 12 and the lower shell 13.

[0045] Furthermore, one or at least two rib plates 11 are provided on the inner walls of the upper shell 12 and the lower shell 13, and a plurality of first conducting members 3 are provided on each rib plate 11, so that the upper shell 12 is conducted with the main board 21 and the adapter 22 through the first conducting members 3, and the lower shell 13 is also conducted with the main board 21 and the adapter 22 through the first conducting members 3. Then, the upper shell 12 and the lower shell 13 are conducted through the second conducting member 4, and the main board 21 is grounded, thereby achieving a better grounding effect of the detection device.

[0046] Preferably, both the upper shell 12 and the lower shell 13 are made of magnesium alloy material, and the inner surfaces of the upper shell 12 and the lower shell 13 are subjected to anti-oxidation passivation treatment, so that the upper shell 12 and the lower shell 13 have excellent conduction performance.

[0047] It should be noted that Figure 1 is an exploded view of the detection device, and the main board assembly 2 is not shown assembled in the lower shell 13. Figure 2 、 Figure 4 and Figure 5 are all cross-sectional views of the corresponding Figure 1 parts when the main board assembly 2 is assembled in the lower shell 13.

[0048] Optionally, the rib plates 11 can be directly formed on the housing 1 and integrally processed with the housing 1 to simplify the processing steps.

[0049] The following is a detailed introduction to the specific structures of the first conducting member 3 and the second conducting member 4:

[0050] As Figure 3 and Figure 6As shown, the first conducting member 3 includes a first clamping portion 31 and a first abutting portion 32. One end of the first abutting portion 32 is connected to the first clamping portion 31. The first clamping portion 31 is clamped on the rib plate 11. The other end of the first abutting portion 32 extends towards the motherboard assembly 2, so that the motherboard 21 or the adapter 22 abuts against the first abutting portion 32. The cross-sectional shape of the first clamping portion 31 in a direction perpendicular to its extending direction is similar to an inverted U-shaped structure. By buckling and clamping the first clamping portion 31 on the rib plate 11, the setting method of the first conducting member 3 is not only more convenient for installation and disassembly, but also makes the installation of the first conducting member 3 more firm and stable. When the motherboard assembly 2 and the adapter 22 are placed in the housing 1, the motherboard 21 abuts against the first abutting portion 32 of the first conducting member 3, thereby realizing the conduction between the motherboard 21 and the housing 1. The adapter 22 abuts against the first abutting portion 32 of another first conducting member 3, thereby realizing the conduction between the adapter 22 and the housing 1. Through the first conducting member 3 with such a structure, the conduction effect between the motherboard 21 and the adapter 22 and the first conducting member 3 is better.

[0051] Further, the position where the motherboard 21 abuts against the first abutting portion 32 is a bare copper area, and the bare copper area is a copper sheet welded on the surface of the motherboard 21 to achieve good conduction between the motherboard 21 and the first abutting portion 32.

[0052] Specifically, when the motherboard assembly 2 and the adapter 22 are placed in the housing 1, both the motherboard assembly 2 and the adapter 22 can press the first abutting portion 32 towards the first clamping portion 31, that is, the first abutting portion 32 undergoes elastic deformation, so that both the motherboard 21 and the adapter 22 can be in full contact with the first abutting portion 32, thereby making the conduction effect better.

[0053] Further, the first clamping portion 31 includes a first top plate 311 and two first side plates 312. The first top plate 311 is connected to one end of the first abutting portion 32. The two first side plates 312 are respectively connected to opposite sides of the first top plate 311, and the two first side plates 312 can be clamped on the rib plate 11. Just clamping the two first side plates 312 on the rib plate 11 can complete the installation of the first clamping portion 31, and the installation operation is more convenient and efficient.

[0054] Further, at least one of the first side plates 312 includes a first concave portion 3121, and the concave direction of the first concave portion 3121 is towards the space between the two first side plates 312, so that the two first side plates 312 are in interference fit with the rib plate 11, thereby making the installation of the first clamping portion 31 more firm.

[0055] In this embodiment, one of the first side plates 312 is recessed towards the assembly gap between the two first side plates 312, so that the two first side plates 312 can clamp the rib plate 11 more firmly, realizing the reliable installation of the first conducting member 3.

[0056] Of course, in other embodiments, both of the two first side plates 312 may have the above-mentioned recesses to further enhance the reliability of the installation of the first conducting member 3 on the rib plate 11.

[0057] In some embodiments, it may also be arranged that the distance between the two first side plates 312 gradually decreases in the direction away from the first top plate 311, so that the two first side plates 312 can be clamped on the rib plate 11.

[0058] Furthermore, the first abutting portion 32 includes an inclined section 321 and an abutting section 322. One end of the inclined section 321 is connected to the first clamping portion 31, the other end of the inclined section 321 is connected to the abutting section 322, and the inclined section 321 gradually moves away from the first clamping portion 31 from one end to the other end. The abutting section 322 is used to abut against the main board 21 or the adapter 22, which can prevent the main board assembly 2 from being in virtual contact with the first abutting portion 32 and make the grounding conduction effect of the main board assembly 2 better.

[0059] Preferably, the abutting section 322 extends in the horizontal direction, that is, the extending direction of the abutting section 322 is parallel to the lower surface of the main board 21 or the adapter 22, so that both the main board 21 and the adapter 22 can be in full contact with the abutting section 322.

[0060] Furthermore, the adapter 22 includes an external socket 221 and an electrical connecting member 222. The external socket 221 is electrically connected to the main board 21 through the electrical connecting member 222. The main board 21 is specifically a circuit board. The external socket 221 is used to connect an external detection terminal, so as to realize the electrical signal transmission between the main board 21 and the detection terminal. The metal shell of the external socket 221 abuts against the first abutting portion 32 of the first conducting member 3 to realize the grounding conduction of the external socket 221.

[0061] Specifically, the electrical connecting member 222 includes a wire and a plug connected to one end of the wire. The other end of the wire is electrically connected to the external socket 221. A socket is arranged on the main board 21, and the plug is inserted into the socket on the main board 21.

[0062] Furthermore, as Figure 7 shown, the second conducting member 4 includes a second clamping portion 41 and a second abutting portion 42. One end of the second abutting portion 42 is connected to the second clamping portion 41. The second clamping portion 41 is clamped on one of the side plates of the upper shell 12 and the lower shell 13, and the other end of the second abutting portion 42 extends towards the other side plate of the upper shell 12 and the lower shell 13. When the upper shell 12 and the lower shell 13 are installed, both the upper shell 12 and the lower shell 13 are in good contact with the second conducting member 4, so that the conduction effect between the upper shell 12 and the lower shell 13 is better.

[0063] Further, the second clamping portion 41 includes a second top plate 411 and two second side plates 412. The two second side plates 412 are respectively connected to opposite sides of the second top plate 411. The two second side plates 412 can be clamped on the side plates of the upper shell 12 or the lower shell 13. One end of the second abutting portion 42 is connected to one of the second side plates 412. Just clamping the two second side plates 412 on the side plates of the upper shell 12 or the lower shell 13 can complete the installation of the second conducting member 4, and the installation operation is more convenient and efficient.

[0064] Specifically, the second clamping portion 41 of the second conducting member 4 in this embodiment is clamped on the side plate of the lower shell 13, and the second abutting portion 42 extends toward the side plate of the upper shell 12. When the upper shell 12 and the lower shell 13 are installed, the side plate of the upper shell 12 is located outside the side plate of the lower shell 13, and the side plate of the upper shell 12 presses the second abutting portion 42 against the side plate of the lower shell 13, that is, the second abutting portion 42 undergoes elastic deformation, and the side plate of the upper shell 12 is in full contact with the second abutting portion 42, thereby making the conduction effect better.

[0065] Of course, in other embodiments, the second clamping portion 41 of the second conducting member 4 can also be clamped on the side plate of the upper shell 12, and the second abutting portion 42 extends toward the side plate of the lower shell 13. When the upper shell 12 and the lower shell 13 are installed, the lower shell 13 presses the second abutting portion 42 against the side plate of the upper shell 12.

[0066] Further, in order to make the installation of the second clamping portion 41 more firm, at least one of the second side plates 412 includes a second concave portion 4121, and the concave direction of the second concave portion 4121 is toward the space between the two second side plates 412. In this embodiment, one of the second side plates 412 is recessed toward the assembly gap between the two second side plates 412 to more firmly clamp the side plate of the upper shell 12 or the lower shell 13, realizing the reliable installation of the second conducting member 4.

[0067] Of course, in other embodiments, both of the two second side plates 412 can have the above-mentioned recesses to further enhance the reliability of the installation of the second conducting member 4 on the side plate of the upper shell 12 or the lower shell 13.

[0068] In some embodiments, it can also be set that the distance between the two second side plates 412 gradually decreases in the direction away from the second top plate 411, so that the two second side plates 412 can be clamped on the side plate of the upper shell 12 or the lower shell 13.

[0069] Preferably, a plurality of second conducting members 4 are provided, and the plurality of second conducting members 4 are arranged along the length direction of the side plate of the lower shell 13 and are clamped on the side plate of the lower shell 13.

[0070] Preferably, the first conducting member 3 and the second conducting member 4 are both made of beryllium bronze, and the surfaces of the first conducting member 3 and the second conducting member 4 are both nickel-plated to improve wear resistance. Beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance, and also has good corrosion resistance, thermal conductivity and electrical conductivity, and does not generate sparks when impacted.

[0071] Further, the second abutting portion 42 includes an extending section 421 and a contacting section 422. One end of the extending section 421 is connected to the second clamping portion 41, and the other end of the extending section 421 is connected to the contacting section 422. The extending section 421 gradually moves away from the second clamping portion 41 from one end to the other end. The contacting section 422 is used for abutting against the side plate of the upper shell 12, and the contacting section 422 has a good abutting effect with the upper shell 12 to prevent a virtual connection between the side plate of the upper shell 12 and the second abutting portion 42.

[0072] Preferably, the contacting section 422 extends in the vertical direction, that is, the extending direction of the contacting section 422 is parallel to the side plate of the upper shell 12, so that the side plates of the upper shell 12 can be fully attached to and contacted with the contacting section 422.

[0073] The assembly process of the detection device in this embodiment is described below:

[0074] First, a plurality of first conducting members 3 are clamped on the rib plates 11 of the upper shell 12 and the lower shell 13, and the second conducting member 4 is clamped on the side plate of the lower shell 13;

[0075] The main board assembly 2 is arranged in the lower shell 13. The main board 21 and the adapter 22 are both fixed to the lower shell 13 by screws. At this time, the main board 21 and the adapter 22 press the first abutting portions 32 of their respective corresponding first conducting members 3;

[0076] The upper shell 12 is installed on the lower shell 13. At this time, the side plates of the upper shell 12 are located outside the side plates of the lower shell 13, and the side plates of the upper shell 12 press the second abutting portions 42 of the second conducting members 4.
