Description

Technical Field

[0001] The utility model belongs to the technical field of image intensifiers, and in particular relates to an image intensifier power supply protection shell with a glue injection hole. Background Art

[0002] The anode ring of the image intensifier tube is close to the power supply shell, and it is difficult for silicone rubber to enter the gap between the anode ring and the power supply, and it cannot provide insulation for the power supply. In addition, during the glue filling and sealing process, due to the low fluidity of silicone rubber, silicone rubber cannot flow into the gap between the power supply shell and the anode ring of the image intensifier. It is necessary to open a hole at the bottom of the image intensifier to inject glue, use pressure to inject glue and make the entire tube full of glue.

[0003] The existing power supply shell is close to the anode ring, and there is a risk of high-voltage discharge and breakdown of the power supply IC. When injecting glue from the bottom of the power supply shell, the pressure causes the image intensifier tube to shift inside the protective shell, resulting in the potting of the entire image intensifier tube failing to meet the use requirements, and there is no guarantee that the silicone rubber will be filled inside the protective shell. If there is a gap between the high-voltage components and the power supply, it cannot provide sufficiently reliable insulation for the power supply. Moreover, when injecting silicone rubber from the bottom, it is only possible to observe whether the glue is filled through the gap between the power supply and the anode surface of the image intensifier, which can easily cause the glue to remain on the anode surface and cause contamination. In addition, the two glue injection processes at the bottom need to use a plug to seal the injection hole, which will cause a small amount of glue to flow out, making the overall glue amount impossible to quantify. When the glue injection cannot be quantified using a machine and pressure is used from bottom to top, the process will become more complicated and a large amount of glue will be lost.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present embodiment provides an image intensifier power supply protective shell with a glue injection hole, comprising a shell 1, a channel 10 for installing an image intensifier tube passes through the middle of the shell 1, a glue injection hole 13 is provided on the side of the shell 1, and a plurality of wiring holes 12 and support ribs 11 are provided on the bottom of the shell 1. Each support rib 11 is arranged around the edge of the port of the channel 10, and a notch is formed between two adjacent support ribs 11. The channel 10 is used to cooperate with the installation of the image intensifier tube, and the notch can allow the wire to pass through.

[0026] As an implementation mode of this embodiment, the side wall of the housing 1 is provided with heat dissipation holes and arc-shaped grooves to improve the heat dissipation effect of the power supply.

[0027] Working process of this utility model:

[0028] During operation of the image intensifier power supply protection shell, the high-voltage power supply is installed in the cavity of the shell 1, one end of the image intensifier tube is inserted into the channel 10, the supporting ribs 11 of the shell 1 are against the anode ring of the image intensifier tube, and silicone rubber is injected from top to bottom into the image intensifier tube through the glue injection hole 13 to complete the glue filling and packaging.
