Description

Technical Field

[0001] This utility model relates to the field of low-light night vision technology, and more specifically, to an image intensifier connection component for a low-light night vision device. Background Technology

[0002] The core component of a low-light night vision device is the image intensifier. It uses the "light-to-electricity-to-light" conversion principle to amplify weak light signals to a level visible to the human eye, thus enabling observation at night or in low-light environments. The image intensifier mainly consists of the following parts: an optical system responsible for focusing weak light onto a photocathode; a photocathode that converts the light signal into photoelectrons; a microchannel plate for electron multiplication; and a fluorescent screen that converts the electronic signal into a visible light image. Image intensifiers are widely used in military, security, and wilderness exploration fields. They provide clear images under extremely low light conditions, helping observers see targets at night or in dim environments.

[0003] The connection of the image intensifier in a night vision device usually depends on the specific device model and design. A common connection method is to connect the image intensifier through a contact seat assembly and an image tube socket. This connection method is highly reliable, but if the conductive spring is damaged, the entire image tube socket needs to be disassembled and replaced, making maintenance and repair difficult.

[0030] The core component of a low-light night vision device is the image intensifier. It uses the "light-to-electricity-to-light" conversion principle to amplify weak light signals to a level visible to the human eye, enabling observation in nighttime or low-light environments. The image intensifier mainly consists of the following parts: an optical system responsible for focusing weak light onto a photocathode; a photocathode that converts the light signal into photoelectrons; a microchannel plate for electron multiplication; and a fluorescent screen that converts the electronic signal into a visible light image. Image intensifiers are widely used in military, security, and wilderness exploration fields. They provide clear images under extremely low light conditions, helping observers see targets at night or in dim environments. Connecting the image intensifier to a night vision device typically depends on the specific device model and design. A common connection method is to connect the image intensifier via a contact socket and an image tube socket. This connection method is highly reliable, but if the conductive spring is damaged, the entire image tube socket needs to be disassembled and replaced, making maintenance and repair difficult. To address the aforementioned issues, this application provides an image intensifier connection assembly for a low-light night vision device. This assembly combines a contact seat group with an image tube seat, and the image tube seat is snapped onto the night vision device. A conductive spring is also snapped onto the image tube seat, facilitating disassembly and maintenance.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this application embodiment provides an image intensifier connection assembly for a low-light night vision device, including an image tube seat 10, an image tube retaining ring 20, and an image intensifier 30. One end of the image tube seat 10 along its axial direction is provided with a first snap-fit ​​structure 11, through which the image tube seat 10 connects to the low-light night vision device. The end of the image tube seat 10 away from the low-light night vision device is provided with a mounting groove 12. The image intensifier 30 is disposed within the mounting groove 12 along the axial direction of the image tube seat 10. At least two symmetrical adjustment structures are provided on the sidewall of the mounting groove 12, used to fix the image intensifier 30 within the mounting groove 12.

Two notches 14 are provided on the side wall of the mounting groove 12. The notches 14 are positioned opposite to the contacts 31 of the enhancer 30. The mounting plate 15 is connected to the notch 14 through a second snap-fit ​​structure. The mounting plate 15 is used to install the conductive spring 16. The conductive spring 16 is elastically attached to the contact 31.

[0032] Specifically, the first snap-fit ​​structure 11 includes a plurality of connecting rods 111 arranged toward the side of the low-light night vision device. The connecting rods 111 extend toward the axis of the vertical image tube seat 10. The low-light night vision device is provided with a plurality of connecting baffles corresponding to the connecting rods 111. The connecting baffles are used to snap-fit ​​between the connecting rods 111 and the image tube seat 10.

The adjustment screw hole 13 is perpendicular to the axis, and a stud 132 with its end face abutting against the image intensifier 30 is provided in the adjustment screw hole 13.

[0034] Specifically, a stepped platform 131 is provided at one end of the adjusting screw hole 13 located on the outside of the image tube base 10 so that the stud head of the stud 132 is lower than the side wall on the outside of the image tube base 10; anti-loosening adhesive is applied to the stud 132.

[0035] Specifically, such as Figure 7 As shown, the second snap-fit ​​structure includes a sliding groove 141 disposed on both sides of the notch 14 along the axis of the image tube seat 10. The mounting plate 15 is provided with sliders 151 on both sides that match the sliding grooves 141. The sliders 151 slide in the sliding grooves 141 to make the mounting plate 15 and the notch 14 slidably connected. In one embodiment of this application, a first magnet is disposed on the bottom wall of the notch 14, and a second magnet is disposed on the side of the mounting plate 15 near the first magnet. When the mounting plate 15 is installed, the mounting plate 15 is slid into the notch 14, and the notch 14 and the mounting plate 15 are fixed by the attraction between the second magnet and the first magnet.

[0036] Specifically, one end of the conductive spring 16 is detachably and fixedly connected to the mounting plate 15, such as... Figure 6 As shown, the conductive spring 16 is fixed to the mounting plate 15 by mounting screws 17, and the other end of the conductive spring 16 away from the mounting plate 15 extends along the axis of the image tube seat 10.

The current sensor is used to transmit current signals to the control center, and the control center is used to transmit alarm signals to the indicator light and the user terminal. The indicator light is located on the outside of the image tube pressure ring 20. When the current sensor detects an abnormal current in the conductive spring 16, it indicates that the conductive spring 16 may be damaged, which can promptly remind the operator to pay attention and troubleshoot the fault.

[0039] In this embodiment, the contact seat assembly is combined with the image tube seat 10, and the image tube seat 10 is snapped onto the low-light night vision device for quick installation. The conductive spring 16 is snapped onto the image tube seat 10 through the mounting plate 15, which facilitates disassembly and maintenance when the conductive spring 16 is damaged.

[0040] The installation process of the image intensifier connection assembly of a low-light night vision device provided in this application embodiment is as follows: During installation, firstly, the conductive spring 16 is installed onto the notch 14 through the mounting plate 15. By rotating the image tube seat 10, the connecting baffle is used to lock between the connecting rod 111 and the image tube seat 10, fixing the image tube seat 10 and the low-light night vision device. Then, the image intensifier 30 is inserted into the mounting groove 12 of the image tube seat 10, and the conductive spring 16 of the image tube seat 10 is aligned with the two contacts 31 of the intensifier 30. The position of the image intensifier 30 is finely adjusted by the stud 132 passing through the adjusting screw hole 13, so that the image intensifier 30 is precisely matched with the eyepiece optical path at the rear end. Finally, the image tube clamping ring 20 is put on the image intensifier 30, and the opening end of the receiving cavity 21 is connected to the low-light night vision device. Finally, the image tube clamping ring 20 is pressed tightly against the image intensifier 30, and the installation is completed.
