[0002] The image intensifier in the night vision device needs to be connected to the sub-board in the battery compartment of the lens barrel to realize the connection of the image intensifier circuit. The sub-board has lead pins that are connected to the contacts of the image intensifier to realize the connection of the image intensifier circuit. However, in the prior art, the sub-board in the battery compartment of the night vision device barrel generally has only two pins. If the night vision device needs to achieve a gain effect, it cannot be achieved. It is necessary to increase the connection between the sub-board and other circuits of the image intensifier to achieve it. However, the components in the prior art cannot meet the versatility of the sub-board. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] As shown in the figure, a universal image tube power supply system includes a sub-board 1, a manual gain control extension line 2 and a gain adjustment PCB connector 3. Two power supply contact pin jacks are arranged on both sides of the front end of the sub-board 1 corresponding to the contacts of the image intensifier 4, namely, the jack P1 11 and the jack P4 15, and the jack P1 11 and the jack P4 15 correspond to the plug-in power supply contact pin P1 111 and the power supply contact pin P4 151, respectively, and the two power supply contact pins can directly contact the contacts of the existing image intensifier 4. Three power supply pin sockets are provided on the sub-board 1 between the socket P1 11 and the socket P4 15, and the sockets P2 12, P5 13 and P3 14 are provided from the socket P1 11 side to the socket P4 15 side, respectively. The sockets P2 12, P5 13 and P3 14 are respectively used to plug and unplug the power supply pins P2 121, P5 131 and P3 141. The power supply pins P2 121, P5 131 and P3 141 are used to increase the gain effect of the image intensifier 4, and the power supply pins P2 121, P5 131 and P3 141 are respectively used in conjunction with the manual gain control extension line 2.

[0025] The manual gain control extension line 2 includes one end connected to the image intensifier 4 and one end attached between two contacts of the image intensifier 4. The end connected to the image intensifier 4 is configured as two concave hole structures or two convex pin structures (the concave hole structure is shown in the figure). This is because some of the existing plug-in interfaces of the image intensifier 4 are convex pin structures and some are concave hole structures. The two contacts of the manual gain control extension line 2 are located exactly between the two contacts of the image intensifier 4 and match the power supply contact pin P2121 and the power supply contact pin P3141 on the sub-board 1.

[0026] Sometimes, when the manual gain control extension cable 2 is not enough, the gain adjustment PCB connector 3 is selected. One end of the gain adjustment PCB connector 3 is used to connect with the image intensifier 4, and the other end of the gain adjustment PCB connector 3 is provided with a connecting plate. The lower end surface of the connecting plate is provided with four pins corresponding to the gain adjustment jack 16 on the sub-board 1. The end of the gain adjustment PCB connector 3 connected to the image intensifier 4 is configured as two concave hole structures or two convex pin structures (the convex pin structure is shown in the figure).

[0027] Specific embodiments:

[0028] When the night vision device does not need the manual gain adjustment function, the power supply contact pin P1 111 and the power supply contact pin P4151 can be directly contacted with the contacts of the image intensifier 4. The compatible image intensifier 4 models include NNVT SMALL ANVIS, L3HARRISMX10160, PHOTONIS SMALL ANVIS, KATOD SMALL ANVIS and ELBIT MX10160.

[0029] There are several situations when the night vision device requires manual gain adjustment function.

[0030] Embodiment 1: When the image intensifier 4 is an image intensifier 4 with three contacts, the three contacts of the image intensifier 4 can directly contact the power supply contact pin P1 111, the power supply contact pin P5 131 and the power supply contact pin P4 151. Applicable image intensifier 4 models include NNVT 18 mm, PHOTONIS 18 mm and KATOD 18 mm image intensifier 4, etc.

[0031] Embodiment 2: When the power supply pins P1 111, P4 151, P3 141 and P2 121 are needed, a manual gain control extension line 2 is used for connection. This method is applicable to image intensifiers 4 of 18 mm MX11769 and the like.

[0032] Embodiment 3: When there is no extra power supply contact pin jack on the sub-board 1, but a gain adjustment jack 16 is reserved, a gain adjustment PCB connector 3 is used, one end of the gain adjustment PCB connector 3 is plugged into the image intensifier 4, and the other end is directly plugged into the gain adjustment jack 16 reserved on the sub-board 1, so as to realize manual gain adjustment. This method is applicable to image intensifier 4 models such as MX11769.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
