Description

Technical Field

[0001] The utility model relates to the technical field of carriers, in particular to a product carrier for optical module temperature testing. Background Art

[0002] Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The transmitting end of an optical module converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals. When a single optical module is powered on, the chip temperature will rise from room temperature to over 100°C within 5 minutes, and the module case temperature will exceed 100°C, with a maximum temperature of over 200°C. When testing multiple optical modules, the test environment temperature must be below 70°C and the air temperature uniformity at any point in the environment must be within ±3°C. When the modules are powered on to test voltage and current stability (for 12 hours or more), the chip temperature of all modules must be below 85°C, the case temperature of all modules below 75°C, and the case temperature uniformity of all modules must be within ±3°C.

[0003] At present, the existing carrier frames for optical module temperature testing on the market are shown in the Chinese patent application with the announcement number CN114308174A. A number of carrier plates for placing optical modules are installed in the heating chamber. The carrier plates are spaced apart along the vertical direction in the heating chamber, and the carrier plates are in direct contact with the heating chamber. In this way, on the one hand, the heating chamber may generate static electricity during operation, and the static electricity acting on the carrier plates may cause damage to the optical modules. The two sides of the carrier plates abut against the side plates, and the two sides of the carrier plates may be worn during the insertion into the heating chamber, thereby affecting the normal use of the carrier plates and thus affecting the normal test results. On the other hand, the spacing between the carrier plates in the prior art is difficult to flexibly adjust, which affects the layout of the measured parts and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a product carrier for optical module temperature testing, which has the advantages of simple structure, static isolation, reduced wear and tear, and convenient adjustment.

[0005] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: a product carrier for optical module temperature testing, including a carrier base; side positioning plates for abutting the side of the optical module circuit board are symmetrically fixedly connected on both sides of the carrier base along the vertical direction based on the sliding adjustment component, and a number of insulating sliding wheels for supporting the bottom surface of the optical module circuit board are connected to the side positioning plates at even intervals along the installation direction of the optical module circuit board, and anti-wear pads for reducing wear on both sides of the optical module circuit board are fixedly connected to the side positioning plates.

[0006] The utility model is further configured as follows: the carrier frame base includes a group of fixing plates arranged at intervals along the vertical direction and fixing rods fixedly connected between the fixing plates along the vertical direction, and four fixing rods are provided, which are respectively arranged at the four corners of the fixing plates.

[0007] The utility model is further configured as follows: the sliding adjustment component includes an adjustment slot opened on the fixed rod along the vertical direction, an adjustment block with an L-shaped structure is fixedly connected to the side positioning plate, an adjustment hole matching the adjustment slot is opened on the adjustment block, and the adjustment slot and the adjustment hole are locked and fixed based on a locking nut.

[0008] The utility model is further configured as follows: the insulating sliding wheel is made of rubber material.

[0009] The utility model is further configured as follows: the anti-wear pad is made of silica gel material.

[0010] The utility model is further configured as follows: the anti-wear pad is fixedly connected to the side positioning plate in an adhesive manner.

[0011] In summary, the present invention has the following beneficial effects:

[0012] 1. By evenly rotating and connecting several insulating sliding wheels on the side positioning plate and providing anti-wear pads on the side positioning plate, the insulating sliding wheels and anti-wear pads prevent direct contact between the optical module circuit board and the carrier frame base, thus preventing static electricity from damaging the optical module and also preventing wear on the side edges of the optical module circuit board.

[0013] 2. The side positioning plate is fixedly connected to the carrier frame base based on the sliding adjustment component. The sliding adjustment component is connected to the side positioning plate and the fixed rod through an adjustment block by opening an adjustment slot on the fixed rod, and the adjustment hole and the adjustment slot are connected based on a locking screw to achieve the fixed connection of the side positioning plate to the fixed rod. When the position of the optical module positioning plate needs to be adjusted, the locking nut is loosened and the position of the adjustment block is adjusted. After the adjustment is completed, it can be tightened. The adjustment is convenient and the structure is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be described in further detail below with reference to the accompanying drawings.

[0020] Example:

[0021] refer to Figures 1 to 4 A product carrier for optical module temperature testing includes a carrier base 1. Side positioning plates 3 for contacting the sides of an optical module circuit board are symmetrically fixedly connected to the carrier base 1 along the vertical direction based on a sliding adjustment component 2. A number of insulating sliding wheels 4 for supporting the bottom surface of the optical module circuit board are evenly spaced and rotatably connected to the side positioning plates 3 along the installation direction of the optical module circuit board. Anti-wear pads 5 for reducing wear on both sides of the optical module circuit board are fixedly connected to the side positioning plates 3. The insulating sliding wheels 4 and the anti-wear pads 5 prevent direct contact between the optical module circuit board and the carrier base 1, thereby preventing static electricity from damaging the optical module and also preventing wear on the sides of the optical module circuit board. In this embodiment, the insulating sliding wheels 4 are made of rubber to ensure sufficient insulation and support. The anti-wear pads 5 are made of silicone and are fixedly connected to the side positioning plates 3 by adhesion. While reducing wear on the sides of the optical module circuit board, they are also easy to replace, improving replacement convenience.

An adjusting hole 23 that cooperates with the adjusting slot 21 is provided on the adjusting block 22. The adjusting slot 21 and the adjusting hole 23 are locked and fixed based on a locking nut. When the position of the optical module positioning plate needs to be adjusted, the locking nut is loosened and the position of the adjusting block 22 is adjusted. After the adjustment is completed, it can be tightened. The adjustment is convenient and the structure is simple.

[0024] Brief description of the usage process: The insulating sliding wheel 4 and the anti-wear pad 5 prevent the optical module circuit board from directly contacting the carrier frame base 1, avoiding damage to the optical module caused by static electricity.
