Abstract
Description
Technical Field
[0001] This utility model belongs to the field of communications, and specifically relates to an improved adhesive fixing structure for plug-and-play detector core filter sheets, which features strong and reliable adhesion, good venting effect, high yield rate, no need for black pressure blocks, low operating cost, and superior performance. Background Technology
[0002] Inserting and removing detector chips requires attaching filters. Currently, a circular mounting surface is typically created on the top of the chip, which is a smooth plane. Before attaching the filter, adhesive needs to be applied to this surface. However, during our use, we found that this circular, smooth surface resulted in insufficient adhesive residue, weak adhesion, and unreliable filter attachment. To address this issue, we applied for an improved mounting structure last year, changing the circle to a square with a frosted surface. This improved the mounting strength to some extent. However, in actual use, a black pressure block is still needed on the filter for greater stability. While this structure with the black pressure block meets certain requirements, it also has significant drawbacks: cumbersome operation, low efficiency, high cost, and the black pressure block can negatively impact filter performance, resulting in poor adhesion and failing to effectively meet the requirements.
[0003] The technical problem to be solved by this utility model is to provide an improved adhesive fixing structure for plug-in detector core filter sheets that is simple and convenient to operate, highly efficient, low in cost, has a larger amount of adhesive residue, stronger adhesion, more secure and reliable mounting, better venting effect, better product performance, high yield, and effectively meets the requirements of use. Utility Model Content
[0004] To address the problems of insufficient adhesive residue, weak adhesion, unreliable filter mounting, poor venting, impact on product performance, low yield, cumbersome and inefficient operation requiring a black pressure block, high cost, and inability to effectively meet usage requirements in existing technologies, this utility model adopts the following technical solution:
[0005] This utility model provides an improved structure for adhesive fixing of a pluggable detector core filter, including a base shell, a diode mounting slot, and a core. The diode mounting slot is fixed on the base shell, and the core is disposed in the diode mounting slot and includes a light-transmitting hole in the center and a filter mounting boss on the outer side. The filter mounting boss is square and has overlapping ears at the middle position of both the left and right sides. The overlapping ears are U-shaped. Venting slots are opened at the middle position of both the upper and lower sides of the filter mounting boss. One end of the venting slot is connected to the light-transmitting hole, and the other end extends to the inner wall of the diode mounting slot. The upper surface of the filter mounting boss is sandblasted roughened.
[0006] The beneficial effects of this utility model are as follows: an additional pair of U-shaped ears are added to the side of the square mounting boss, resulting in a larger amount of adhesive residue and a stronger and more reliable adhesive bond. There is no need to place a black pressure block, making the operation convenient, simple, and efficient. The vent hole is extended to the inner wall of the slot, resulting in better venting effect, higher yield, and effective satisfaction of usage requirements. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of the structure of one embodiment of the present utility model.
[0008] Figure 2 This is a schematic diagram of the traditional structure. Detailed Implementation
[0009] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0010] Please see Figure 1 An improved structure for adhesive fixing of a pluggable detector core filter includes a base shell 1, a diode mounting slot 2, and a core 3. The diode mounting slot 2 is fixed on the base shell 1. The core 3 is disposed in the diode mounting slot 2 and includes a light-transmitting hole 31 in the center and a filter mounting boss 32 on the outer side. The filter mounting boss 32 is square and has overlapping ears 33 at the middle position of both the left and right edges. The overlapping ears 33 are U-shaped, so that more adhesive is retained during dispensing, and the mounting is more firm and reliable. There is no need to place a black pressure block, and the operation is convenient and simple. The filter mounting boss 32 has venting slots 34 at the middle position of both the upper and lower sides. One end of the venting slot 34 is connected to the light-transmitting hole 31, and the other end extends to the inner wall of the diode mounting slot 2, thus increasing the venting length and improving the venting effect. The upper surface of the filter mounting boss is sandblasted rough.
[0011] The beneficial effects of this utility model are as follows: an additional pair of U-shaped ears are added to the side of the square mounting boss, resulting in a larger amount of adhesive residue and a stronger and more reliable adhesive bond. There is no need to place a black pressure block, making the operation convenient, simple, and efficient. The vent hole is extended to the inner wall of the slot, resulting in better venting effect, higher yield, and effective satisfaction of usage requirements.
[0012] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
