[0043] Refer to the attached drawings of the specification of this utility model Figures 1 to 11 A sonar according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the sonar includes an electronic cabin 10, a wiring head 20, at least one circuit board 30 and a transducer 40.

[0044] Reference Fig.10 and Fig.11The electronic cabin 10 has a cabin cavity 11 and a hatch 12 connected to the cabin cavity 11, and the wiring head 20 is watertightly installed in the electronic cabin 10. Specifically, the electronic cabin 10 includes a bottom wall 13 and an annular wall 14, the annular wall 14 integrally extends upward from the periphery of the bottom wall 13 to form the cabin cavity 11 of the electronic cabin 10 between the bottom wall 13 and the annular wall 14, and the annular wall 14 surrounds the hatch 12 of the electronic cabin 10, wherein the bottom wall 13 has a bottom wall through hole 131, and the bottom wall through hole 131 is connected to the cabin cavity 11 of the electronic cabin 10.

[0045] Reference Figure 4 The terminal head 20 has a terminal head outer end 21 and a terminal head inner end 22, the terminal head outer end 21 and the terminal head inner end 22 are coaxial, and the radius of the terminal head outer end 21 is greater than the radius of the bottom wall through hole 131 of the bottom wall 13, and the radius of the terminal head inner end 22 is smaller than the radius of the bottom wall through hole 131 of the bottom wall 13, wherein the terminal head inner end 22 of the terminal head 20 extends into the bottom wall through hole 131 of the bottom wall 13 into the electronic cabin 10 After the cabin cavity 11, the outer end 21 of the terminal head can be attached to the bottom wall 13, wherein the sonar further includes a nut 50, and the nut 50 is screwed on the inner end 22 of the terminal head 20 in the cabin cavity 11 of the electronic cabin 10, so that the outer end 21 of the terminal head and the nut 50 can clamp the bottom wall 13 on opposite sides of the bottom wall 13, and the outer end 21 of the terminal head is tightly attached to the bottom wall 13, so that the terminal head 20 is watertightly installed in the electronic cabin 10.

[0046] It can be understood that in order to further increase the watertightness of the electronic cabin 10 and the terminal head 20, the sonar can set a deformable gasket 60 between the bottom wall 13 of the electronic cabin 10 and the terminal head outer end 21 of the terminal head 20, which can be made of silicone or rubber. After the nut 50 is screwed onto the terminal head inner end 22 of the terminal head 20, the terminal head outer end 21 of the terminal head 20 and the bottom wall 13 can squeeze and deform the gasket 60, so that the gasket 60 prevents water from entering the cabin cavity 11 of the electronic cabin 10 through the combination position of the terminal head 20 and the bottom wall 13 of the electronic cabin 10.

[0047] Reference Figures 4 to 11, the circuit board 30 is fixedly mounted on the electronic cabin 10 in the manner of being located in the cabin cavity 11 of the electronic cabin 10, so that the length of a first conductive member 100 used to connect the circuit board 30 and the terminal head 20 can be shortened, avoiding the problem that the first conductive member 100 is touched by the electronic cabin 10 and the detection signal of the sonar is disturbed, which is crucial to ensure the reliability of the sonar. In some embodiments of the sonar of the present invention, the first conductive member 100 can be a connecting wire, which can connect the circuit board 30 and the terminal head 20 by, but not limited to, flying wire technology.

[0048] The transducer 40 is installed in the electronic cabin 10 in a manner of closing the hatch 12 of the electronic cabin 10, and the transducer 40 and the circuit board 30 are connected through a second conductive member 200, so that the electronic cabin 10 and the transducer 40 can provide a watertight space for isolating the circuit board 30 from the external environment. In some embodiments of the sonar of the present invention, the second conductive member 200 can be a flexible printed circuit (FPC).

[0049] In the attached Figures 1 to 11 In the specific example of the sonar of the present invention shown, the wiring head 20 is installed watertightly on the electronic cabin 10, the circuit board 30 is fixedly installed on the electronic cabin 10 in the manner of being located in the cabin cavity 11 of the electronic cabin 10, and the circuit board 30 and the wiring head 20 are connected through the first conductive member 100, the transducer 40 is installed on the electronic cabin 10 in the manner of closing the hatch 12 of the electronic cabin 10, and the transducer 40 and the circuit board 30 are connected through the second conductive member 200. Different from the solution of the prior art that the circuit board is installed on the transducer and the transducer suspends the circuit board on the electronic cabin, the circuit board 30 of the sonar of the present invention is installed on the electronic cabin 10, so that the length dimension of the first conductive member 100 between the wiring head 20 and the circuit board 30 can be greatly shortened, avoiding the problem that the detection signal of the sonar is interfered by the first conductive member 100 touching the electronic cabin 10.

[0050] Preferably, the circuit board 30 stands in the cabin cavity 11 of the electronic cabin 10, which makes the height direction of the circuit board 30 consistent with the height direction of the electronic cabin 10, so that the top of the circuit board 30 is adjacent to the hatch 12 of the electronic cabin 10. Since the transducer 40 is installed in the electronic cabin 10 in a manner of closing the hatch 12 of the electronic cabin 10, the length dimension of the second conductive member 200 between the circuit board 30 and the transducer 40 can be greatly shortened, thereby avoiding the problem that the detection signal of the sonar is interfered with due to the second conductive member 200 touching the electronic cabin 10.

[0051] Continue to refer to the attached Figures 4 to 11 The electronic cabin 10 has at least one pair of slots 15, and the pair of slots 15 are arranged on opposite sides of the electronic cabin 10 on the inner wall of the electronic cabin 10, and the extension direction of the pair of slots 15 is consistent with the height direction of the electronic cabin 10, wherein the opposite ends of the circuit board 30 are respectively inserted into the pair of slots 15 of the electronic cabin 10 from top to bottom, so as to stand and install the circuit board 30 in the cabin cavity 11 of the electronic cabin 10. In this way, on the one hand, since the circuit board 30 is installed in the cabin cavity 11 of the electronic cabin 10, the main body of the circuit board 30 may not contact with other objects, and when the circuit board 30 is assembled in the electronic cabin 10, the main body of the circuit board 30 may be avoided. On the other hand, the bottom of the circuit board 30 is adjacent to the terminal head 20, which is beneficial to significantly shortening the length of the first conductive member 100 used to connect the circuit board 30 and the terminal head 20, thereby avoiding the problem that the first conductive member 100 touches the electronic cabin 10 and causes the detection signal of the sonar to be interfered with. At the same time, the top of the circuit board 30 is adjacent to the transducer 40, which is beneficial to shortening the length of the second conductive member 200 used to connect the circuit board 30 and the transducer 40, thereby avoiding the problem that the second conductive member 200 is touched by the electronic cabin 10 and causes the detection signal of the sonar to be interfered with.

[0052] In the attached Figures 1 to 11In this specific example of the sonar of the present invention, the electronic compartment 10 has a plurality of pairs of slots 15, and the slots 15 on the same side of the electronic compartment 10 are spaced apart from each other, wherein the number of the circuit boards 30 is multiple, and the opposite ends of each circuit board 30 are respectively inserted into each pair of slots 15 of the electronic compartment 10 from top to bottom, so that there can be gaps between adjacent circuit boards 30 to avoid the problem of heat concentration. That is to say, the plurality of circuit boards 30 fixedly mounted on the electronic compartment 10 are independent of each other in the compartment cavity 11 of the electronic compartment 10, and there are gaps between adjacent circuit boards 30 as heat dissipation spaces, which are conducive to achieving rapid heat dissipation of these circuit boards 30 and avoiding the problem of heat concentration.

[0053] Further, please refer to the attached Figures 4 to 11 The electronic cabin 10 is provided with at least one pair of clamping columns 16 on opposite sides of the inner wall. The extension direction of the clamping columns 16 is consistent with the height direction of the electronic cabin 10. The clamping slot 15 extends downward from the top of the clamping column 16. After the end of the circuit board 30 is clamped into the clamping slot 15 of the electronic cabin 10 from top to bottom, the clamping column 16 clamps the opposite sides of the circuit board 30 at the end of the circuit board 30, so that the circuit board 30 is installed upright in the cabin cavity 11 of the electronic cabin 10. That is to say, the clamping column 16 can limit the end of the circuit board 30 to prevent the circuit board 30 from shaking in the cabin cavity 11 of the electronic cabin 10. At the same time, the provision of the clamping column 16 can strengthen the strength of the annular wall 14 of the electronic cabin 10 to prevent the annular wall 14 from deforming.

[0054] Furthermore, the top of the circuit board 30 is flush with the top of the mounting column 16 of the electronic compartment 10, and the top of the mounting column 16 has a screw hole 161, wherein the sonar further includes a locking assembly 70, the locking assembly 70 includes at least one pair of first screws 71, the first screws 71 are screwed into the screw holes 161 of the mounting column 16 of the electronic compartment 10, and the nuts 711 of the first screws 71 press the top of the circuit board 30 to prevent the circuit board 30 from moving upward relative to the electronic compartment 10, thereby reliably standing and installing the circuit board 30 in the compartment 11 of the electronic compartment 10. In other words, the first screws 71 are used to lock the circuit board 30 on the mounting column 16 of the electronic compartment 10, limit the top of the circuit board 30, prevent the circuit board 30 from shaking relative to the electronic compartment 10, and ensure that the circuit board 30 is reliably set in the compartment 11 of the electronic compartment 10.

[0055] Reference Figure 4The transducer 40 includes an assembly frame 41, a receiving part 42, a transmitting part 43 and a vulcanizing part 44, wherein the assembly frame 41 includes a frame body 411, a combining body 412 integrally extending upward from the frame body 411, and an inserting body 413 integrally extending downward from the bottom of the frame body 411, wherein the vulcanizing part 44 is integrally combined with the combining body 412 in a manner of wrapping at least a portion of the receiving part 42 and the transmitting part 43, so that the assembly frame 41, the receiving part 42, the transmitting part 43 and the vulcanizing part 44 form a whole. After the receiving part 42 and the transmitting part 43 are respectively connected to the circuit board 30 through the second conductive piece 200, the insert body 413 of the assembly frame 41 is inserted into the cabin cavity 11 through the hatch 12 of the electronic cabin 10, and the frame body 411 of the assembly frame 41 closes the hatch 12 of the electronic cabin 10, so that the transducer 40 is installed in the electronic cabin 10, and the hatch 12 of the electronic cabin 10 is closed by the transducer 40. Since the circuit board 30 is installed in the cabin cavity 11 of the electronic cabin 10 from top to bottom, the top of the circuit board 30 is adjacent to the hatch 12 of the electronic cabin 10. At the same time, since the frame 411 of the assembly frame 41 of the transducer 40 closes the hatch 12 of the electronic cabin 10, the length dimension of the second conductive member 200 used to connect the receiving part 42 and the circuit board 30 and the length dimension of the second conductive member 200 used to connect the transmitting part 43 and the circuit board 30 can be greatly shortened, thereby avoiding the problem that the second conductive member 200 is touched by the electronic cabin 10 and the detection signal of the sonar is interfered with.

[0056] In the attached Figures 1 to 11 In this specific example of the sonar of the present invention shown, the size of the frame 411 of the assembly frame 41 is larger than the size of the hatch 12 of the electronic cabin 10, so that after the plug-in body 413 of the assembly frame 41 is inserted into the cabin cavity 11 through the hatch 12 of the electronic cabin 10, the edge of the frame 411 of the assembly frame 41 can be placed against the position of the electronic cabin 10 for enclosing the hatch 12. In this way, the assembly frame 41 and the annular wall 14 of the electronic cabin 10 cooperate with each other to control the insertion depth of the plug-in body 413 into the cabin cavity 11 of the electronic cabin 10, avoid the plug-in body 413 colliding with the circuit board 30 and avoid the second conductive member 200 from being desoldered or falling off from the circuit board 30, the receiving part 42 and / or the transmitting part 43, so as to ensure the reliability of the sonar.

[0057] Continue to refer to the attached Figures 1 to 11The sonar of the present invention further includes a lock ring 80 for locking the electronic cabin 10 and the transducer 40. Specifically, the electronic cabin 10 is provided with an annular first lock groove 17 on the inner wall and a threading hole 18 connected to the first lock groove 17 on the outer wall, and the insert body 413 of the assembly frame 41 of the transducer 40 has an annular second lock groove 4131. After the insert body 413 of the assembly frame 41 is inserted into the cabin cavity 11 through the hatch 12 of the electronic cabin 10, the second lock groove 4131 of the insert body 413 is located on the inner side of the first lock groove 17 of the electronic cabin 10, wherein the locking ring 80 is formed after the wire 300 passes through the threading hole 18 of the electronic cabin 10 and the first lock groove 17 of the electronic cabin 10 and the second lock groove 4131 of the insert body 413.

[0058] It can be understood that since the assembly frame 41 and the annular wall 14 of the electronic cabin 10 cooperate with each other to control the depth of the insertion body 413 into the cabin cavity 11 of the electronic cabin 10, after the assembly frame 41 is leaned against the position of the electronic cabin 10 with the frame body 411 to enclose the hatch 12, the height position of the first locking groove 17 of the electronic cabin 10 and the height position of the second locking groove 4131 of the insertion body 413 can be consistent, and the first locking groove 17 of the electronic cabin 10 is located on the outside of the second locking groove 4131 of the insertion body 413, so that the wire 300 can pass through the threading hole 18 of the electronic cabin 10 into the first locking groove 17 of the electronic cabin 10 and the second locking groove 4131 of the insertion body 413 to form the locking ring 80.

[0059] That is, the locking ring 80 is hidden between the electronic cabin 10 and the transducer 40, and the outer side of the locking ring 80 is held in the first locking groove 17 of the electronic cabin 10, and the inner side of the locking ring 80 is held in the second locking groove 4131 of the insert 413, so that the locking ring 80 can lock the electronic cabin 10 and the transducer 40 to prevent the transducer 40 from moving in the height direction relative to the electronic cabin 10. Preferably, the wire 300 can be made of nylon, so that the locking ring 80 formed by the wire 300 has good shear resistance, ensuring that the transducer 40 is reliably installed in the electronic cabin 10.

[0060] Preferably, at least one end of the locking ring 80 is exposed to the threading hole 18 of the electronic cabin 10, so that the locking ring 80 can be pulled out from the first locking groove 17 of the electronic cabin 10 and the second locking groove 4131 of the insert 413 through the threading hole 18 of the electronic cabin 10 to disassemble the electronic cabin 10 and the transducer 40 for the maintenance of the sonar. It can be understood that after the sonar is repaired, first, the transducer 40 is installed in the electronic cabin 10, and the hatch 12 of the electronic cabin 10 is closed by the transducer 40, and then another wire 300 is inserted into the first locking groove 17 of the electronic cabin 10 and the second locking groove 4131 of the insert 413 through the threading hole 18 of the electronic cabin 10 to form the locking ring 80.
