[0032] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following combination Figure 1-Figure 5 The utility model describes a towed array circuit connection device.

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides a towed array circuit connection device 1, comprising an end cap 11 and a circuit board connection assembly 12. The end cap 11 is configured to be mounted on one end of the signal amplification compartment 2. The end cap 11 is provided with a socket into which a pin 111 is inserted. The circuit board connection assembly 12 is disposed on one side of the end cap 11. One end of the pin 111 is electrically connected to the circuit board connection assembly 12, and the other end of the pin 111 is configured to be electrically connected to an external circuit. The circuit board connection assembly 12 is configured to be electrically connected to the signal amplification circuit board 21 within the signal amplification compartment 2.

[0035] It is understood that the towed array circuit connection device 1 of this embodiment is intended to be disposed within a signal amplification chamber 2 to connect the signal amplification circuit board 21 within the chamber 2 to an external circuit. Specifically, the end cap 11 of this embodiment is disposed at one end of the chamber 2 and can cooperate with the chamber body 22 of the chamber 2 to form a closed chamber, thereby protecting the electrical components within. The end cap 11 is provided with a socket for receiving a pin 111. The end of the pin 111 facing outside the closed chamber is used for electrical connection to an external circuit, while the end of the pin 111 facing inside the closed chamber is used for electrical connection to a circuit board connection assembly 12 within the closed chamber. The circuit board connection assembly 12 is electrically connected to the signal amplification circuit board 21 within the closed chamber, enabling the signal amplification circuit board 21 to connect to the external circuit via the circuit board connection assembly 12 and the pin 111. The circuit board connection assembly 12 acts as a busbar, eliminating the need for complex connection circuitry. This helps reduce the number of signal amplification chambers 2, shortens the length of wires within the chamber, and reduces signal interference between wires.

[0036] The towed array circuit connection device 1 of the present invention is provided with an end cap 11 that can cooperate with the body 22 of the signal amplification chamber 2 to form a closed chamber. A pin 111 is inserted into the end cap 11, and the two ends of the pin 111 are respectively electrically connected to the external circuit and the circuit board connection assembly 12 to transmit electrical signals. The circuit board connection assembly 12 is used to connect to the signal amplification circuit board 21 to transmit electrical signals between the pin 111 and the signal amplification circuit board 21. The circuit board connection assembly 12 can serve as a busbar and transfer. Each port of the signal amplification circuit board 21 is uniformly connected to the circuit board connection assembly 12, which helps to simplify the connection circuit, thereby shortening the number and length of wires in the signal amplification chamber 2 and reducing signal interference between the wires. At the same time, the reduction in the number and length of wires in the signal amplification chamber 2 helps to reduce the overall size of the signal amplification chamber 2 and improve the pressure resistance of the signal amplification chamber 2.

[0037] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 As shown, the circuit board connection assembly 12 includes an adapter circuit board 121 and female connector pins 122 disposed on the adapter circuit board 121. The female connector pins 122 correspond to the plug pins 111 and are provided with connector ports. The plug pins 111 connect to the corresponding connector ports. The adapter circuit board 121 is used to electrically connect to the signal amplification circuit board 21.

[0038] In this embodiment, the adapter circuit board 121 is used to connect to the signal amplification circuit board 21 to converge electrical signals, thereby enabling transmission of electrical signals between the signal amplification circuit board 21, the pins 111, and the external circuit. Furthermore, female connector pins 122 are provided on the adapter circuit board 121 corresponding to the pins 111. These female connector pins 122 are provided with plug ports for interfacing with the pins 111. This allows users to more conveniently connect the adapter circuit board 121 to the pins 111, eliminating the need to solder wires between the pins 111 and the adapter circuit board 121 to avoid signal interference between the wires. This results in a simple structure and is convenient and practical.

[0039] It is understandable that, according to the requirements of circuit design, a plurality of plug-in holes can be provided on the end cover 11, and accordingly, a plurality of pins 111 and connecting female pins 122 are also provided, and the plurality of pins 111 are inserted into the plug-in holes one by one and connected to the connecting female pins 122 one by one.

[0040] Specifically, in some embodiments, Figure 5 As shown, a mounting hole is provided on the adapter circuit board 121, and the connecting female pin 122 is installed in the mounting hole.

[0041] In some embodiments, as Figure 3 、 Figure 4 and Figure 5As shown, one of the end cover 11 and the circuit board connection assembly 12 is provided with a positioning column 112, and the other is provided with a positioning hole 124 corresponding to the positioning column 112. The positioning column 112 is inserted into the corresponding positioning hole 124 to align the pin 111 with the corresponding plug port.

[0042] In this embodiment, by providing a positioning column 112 and a positioning hole 124 on the end cover 11 and the circuit board connection assembly 12 respectively, the positioning column 112 and the positioning hole 124 are plugged into each other to position the end cover 11 and the circuit board connection assembly 12, so that the pin 111 and the corresponding plug-in port are aligned with each other, so that the installer can plug the pin 111 and the plug-in port into each other, which makes installation more convenient and less likely to damage the pin 111.

[0043] It is understood that the positions of the positioning posts 112 and the positioning holes 124 can be interchanged. For example, the positioning posts 112 can be mounted on the end cap 11, and the positioning holes 124 can be provided in the circuit board connection assembly 12. Alternatively, the positioning posts 112 can be mounted on the circuit board connection assembly 12, and the positioning holes 124 can be provided in the end cap 11.

[0044] In some embodiments, as Figure 1 and Figure 4 As shown, the circuit board connecting assembly 12 is provided with a first clamping portion 123 , and the first clamping portion 123 is used to clamp with the second clamping portion 211 on the signal amplifying circuit board 21 .

[0045] In this embodiment, by providing a first clamping portion 123 on the circuit board connection assembly 12, the first clamping portion 123 can be clamped and fixed with the second clamping portion 211, so as to clamp and fix the circuit board connection assembly 12 and the signal amplifying circuit board 21 to each other, so that the circuit board connection assembly 12 and the signal amplifying circuit board 21 will not shake relative to each other, thereby making the electrical connection between the two more stable and reliable, and at the same time helping to shorten the length of the connecting wire between the two and reduce signal interference of the wire.

[0046] Specifically, one of the first clamping portion 123 and the second clamping portion 211 is a clamping slot, and the other is a clamping protrusion matched with the clamping slot.

[0047] In some embodiments, as Figure 4 As shown, there are two first clamping portions 123 , and the two first clamping portions 123 are disposed on the outer wall of the circuit board connecting assembly 12 and located on opposite sides of the outer wall of the circuit board connecting assembly 12 .

[0048] In this embodiment, by providing two first clamping portions 123, and the two first clamping portions 123 are respectively located on opposite sides of the outer wall of the circuit board connection assembly 12, the two first clamping portions 123 can respectively engage with the two second clamping portions 211 on both sides of the board body of the signal amplifying circuit board 21, making the clamping structure between the signal amplifying circuit board 21 and the circuit board connection assembly 12 more stable and reliable.

[0049] Preferably, the length of the positioning post 112 is greater than the length of the portion of the pin 111 located on the side of the plug port. When inserting the pin 111 into the plug port, the installer can first align the positioning post 112 with the positioning hole 124, insert the positioning post 112 into the positioning hole 124, and then, with the positioning hole 124 and the positioning post 112 aligned, the pin 111 and the plug port can be plugged together.

[0050] In some embodiments, as Figure 3 As shown, a sealing member 113 is provided between the plug hole and the plug pin 111 to close the gap between the plug hole and the plug pin 111 .

[0051] In this embodiment, a seal 113 is provided between the plug hole and the plug pin 111, and the seal 113 can fill and seal the gap between the plug hole and the plug pin 111, so that when the end cover 11 is installed at one end of the signal amplifying cabin 2, the airtightness and watertightness of the end cover 11 can be ensured, thereby enhancing the sealing of the cabin inside the signal amplifying cabin 2 to protect the electrical components in the cabin.

[0052] Specifically, in some embodiments, the seal 113 is an insulating seal. In this embodiment, the insulating seal can provide insulation between the end cap 11 and the pin 111, preventing electrical conduction between the end cap 11 and the pin 111, which could cause a short circuit in the electrical components within the signal amplifying chamber 2. Specifically, the seal 113 can be made of glass.

[0053] It is understood that the end cap 11 can be made of metal to provide sufficient strength to improve the pressure resistance of the entire device. Specifically, the end cap 11 can be made of a titanium alloy and is manufactured by combining the titanium alloy and glass using a glass sintering process. To meet the process requirements of the glass sintering process, grooves can be designed on both sides of the end cap 11 to reduce the cross-sectional thickness of the end cap 11.

[0054] In some embodiments, as Figure 1 and Figure 3 As shown, the towed array circuit connection device 1 further includes a sealing ring 13. An annular groove 114 is circumferentially formed on the outer peripheral wall of the end cap 11, and the sealing ring 13 is sleeved within the annular groove 114. The outer side of the sealing ring 13 protrudes outside the annular groove 114 and is used to abut against the wall of the signal amplification cabin 2.

[0055] In this embodiment, an annular groove 114 is provided on the outer peripheral wall of the end cover 11, and the annular groove 114 is used to fix the sealing ring 13. The thickness of the sealing ring 13 is greater than the depth of the annular groove 114, so that the outer ring of the sealing ring 13 can protrude out of the annular groove 114. When the end cover 11 is installed in the signal amplifying cabin 2, the outer peripheral wall of the sealing ring 13 abuts against the wall of the signal amplifying cabin 2 to fill and close the gap between the outer wall of the end cover 11 and the wall of the signal amplifying cabin 2, thereby enhancing the sealing of the cabin inside the signal amplifying cabin 2 to protect the electrical components in the cabin.

[0056] On the other hand, Figure 1 and Figure 2 As shown, the present invention further provides a signal amplification chamber 2, comprising a chamber body 22, a signal amplification circuit board 21, and a towed array circuit connection device 1 according to any of the aforementioned embodiments. The chamber body 22 defines a mounting cavity with openings at both ends. The signal amplification circuit board 21 is disposed within the mounting cavity. The circuit board connection assemblies 12 of the two towed array circuit connection devices 1 are respectively connected to the ends of the signal amplification circuit board 21, and the end caps 11 of the two towed array circuit connection devices 1 are respectively mounted to the two openings of the mounting cavity.

[0057] In this embodiment, an installation cavity is provided in the cabin 22 for accommodating and installing the signal amplifying circuit board 21 and the towed array circuit connecting device 1. Openings are provided at both ends of the installation cavity to facilitate placing the signal amplifying circuit board 21 and the towed array circuit connecting device 1 into the installation cavity. The signal amplifying circuit board 21 can be used to amplify acoustic signals, and the circuit board connecting components 12 of the two towed array circuit connecting devices 1 are respectively connected to the two ends of the signal amplifying circuit board 21, so that the signal amplifying circuit board 21 can be electrically connected to the external circuit through the circuit board connecting components 12 at both ends and the pins 111 on the end cover 11 to transmit electrical signals. The end covers 11 of the two towed array circuit connecting devices 1 can respectively close the two openings of the installation cavity to protect the electrical components in the installation cavity.

[0058] It is understandable that the signal amplifying cabin 2 of this embodiment also has the advantages of the towed array circuit connection device 1 described above by adopting the towed array circuit connection device 1 described above, which will not be described in detail here.

[0059] Specifically, in some embodiments, the signal amplifying cabin 2 also includes a fixing member 23, and a plurality of first fixing holes are circumferentially spaced apart at positions of the cabin body 22 corresponding to the two end covers 11, and second fixing holes are provided on the end covers 11 corresponding one to one to the first fixing holes. The fixing member 23 is passed through the first fixing hole and the second fixing hole to fix the end cover 11 and the cabin body 22.

[0060] In this embodiment, the cabin body 22 and the end cover 11 are respectively provided with first fixing holes and second fixing holes along the circumferential direction, and the fixing members 23 are passed through the first fixing holes and the second fixing holes to fix the end cover 11 and the cabin body 22 to each other, so as to prevent the end cover 11 from rotating or sliding in the cabin body 22. After the position of the end cover 11 is fixed, the circuit board connection assembly 12 and the signal amplification circuit board 21 between the two end covers 11 can also be limited, thereby making the electrical components in the entire signal amplification cabin 2 more stable and reliable.

[0061] Specifically, the fixing member 23 may be a fastening bolt, and the first fixing hole and the second fixing hole are both screw holes adapted to the fastening bolt.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
