Description

Technical Field

[0002] The launch cabin is a key component of the sonar. The core components of the launch cabin are the cabin and the launch circuit unit arranged in the cabin. The launch circuit unit is composed of a series of circuit boards and transformers. The connection between the two circuit boards and between the circuit board and the transformer is achieved through the flying wire technology. Taking the connection relationship between the circuit board and the transformer as an example, one end of a wire is soldered to the circuit board through solder paste, and the other end is soldered to the transformer through solder paste, so as to achieve the conductive connection between the circuit board and the transformer. There are many defects in the way of connecting the two circuit boards and connecting the circuit board and the transformer through the flying wire technology. For example, both opposite ends of the wire need to be soldered, resulting in low assembly efficiency, and the consistency of the solder joints is poor, which easily leads to the overall performance of the launch cabin. For example, in the process of installing the launch circuit unit in the cavity of the cabin, due to the narrow process of the cavity, the wire needs to be bent to be inserted into the cavity of the cavity. In the process of bending the wire and inserting the wire into the cavity of the cavity, the welding position of the wire and the circuit board and the wire and the transformer will be stressed and easily desoldering.

[0048] Continue to refer to the attached Figures 3 to 5 , a group of the transmitting circuit boards 31 further includes a third side circuit board 316, the bottom of the third side circuit board 316 is inserted into and directly conductively connected to the bottom circuit board 311, and the side of the third side circuit board 316 is inserted into and directly conductively connected to the first side circuit board 313, so that the third side circuit board 316 can ensure the reliability of the insertion relationship between the first side circuit board 313 and the bottom circuit board 311, thereby further enhancing the structural stability of the transmitting circuit unit 30.

[0049] Specifically, the bottom circuit board 311 has a second bottom board insertion hole 3113, the first side circuit board 313 has a side board insertion hole 3133, and the third side circuit board 316 has a second bottom board insertion section 3161 and a side board insertion section 3162.

[0050] After the bottom of the first side circuit board 313 is inserted into and directly conductively connected to the bottom circuit board 311, the top of the first side circuit board 313 is inserted into and directly conductively connected to the top circuit board 312, the bottom of the second side circuit board 314 is inserted into and directly conductively connected to the bottom circuit board 311, and the top of the second side circuit board 314 is inserted into and directly conductively connected to the top circuit board 312, a group of the transmitting circuit boards 31 form a accommodating cavity 317 between the bottom circuit board 311, the top circuit board 312, the first side circuit board 313 and the second side circuit board 314.

For example, screws can be used to lock the top of the transformer module 32 to the top circuit board 312. In this way, on the one hand, the transformer module 32 is surrounded by a group of the transmitting circuit boards 31 and the transformer module 32 is reliably accommodated in the accommodating cavity 317 formed by a group of the transmitting circuit boards 31. On the other hand, the plug-in relationship between the transformer module 32 and the bottom circuit board 311, the top circuit board 312 and the second side circuit board 314 and the locking relationship between the transformer module 32 and the top circuit board 312 are conducive to further enhancing the structural stability of the transmitting circuit unit 30.

[0051] Reference Figures 6 to 9The transformer module 32 includes a plurality of transformers 321, a module circuit board 322 and a shell 323, wherein at least one transformer 321 is respectively arranged on opposite sides of the module circuit board 322, and the transformer 321 is connected to the module circuit board 322, for example, the transformer 321 can be directly welded to the module circuit board 322, wherein the shell 323 includes a left shell 3231 and a right shell 3232, the left shell 3231 is arranged on the left side of the module circuit board 322 and covers the transformer 321 located on the left side of the module circuit board 322, the right shell 3232 is arranged on the right side of the module circuit board 322 and covers the transformer 321 located on the right side of the module circuit board 322, and the pin 320 of the module circuit board 322 extends to the outside of the shell 323 through the gap between the left shell 3231 and the right shell 3232.

[0052] Since the transformer 321 is disposed on both opposite sides of the module circuit board 322, the transformer module 32 can have reduced length and width to reduce the space requirement of the accommodating cavity 317, thereby reducing the size requirement of a group of the transmitting circuit boards 31, so that the overall size of the transmitting circuit unit 30 can be smaller, thereby reducing the space requirement of the cabin 11 of the cabin body 10. At the same time, since the left shell 3231 covers the transformer 321 located on the left side of the module circuit board 322 and the right shell 3232 covers the transformer 321 located on the right side of the module circuit board 322, the transformer 321 and the module circuit board 322 can be hidden, so that in the process of assembling the transmitting cabin, the transformer 321 and the module circuit board 322 can be prevented from being collided or scratched, so as to ensure the reliability of the transformer module 32. In addition, after passing through the screw hole of the top circuit board 312, the screw extends to the threaded hole of the left housing 3231 or the right housing 3232, so as to achieve reliable installation of the top circuit board 312 and the transformer module 32, and thus, the left housing 3231 and the right housing 3232 provide screw traction points. In addition, after passing through the screw hole of the first side circuit board 313, the screw extends to the threaded hole of the left housing 3231 or the right housing 3232, so as to achieve reliable installation of the first side circuit board 313 and the transformer module 32, and after passing through the screw hole of the second side circuit board 314, the screw extends to the threaded hole of the left housing 3231 or the right housing 3232, so as to achieve reliable installation of the second side circuit board 314 and the transformer module 32, and thus, the left housing 3231 and the right housing 3232 provide screw traction points.

[0053] Preferably, the transformer 321 has a pair of notches 3211, and the soldering points for soldering the transformer 321 and the module circuit board 322 are located in the notches 3211 of the transformer 321.
