Description

Technical Field

[0001] The present invention relates to the field of chassis assembly in the communication field, and more specifically, to a windshield tray installed in a chassis. Background Art

[0002] At present, a certain size of wind shield needs to be installed on the tray of some orthogonal communication chassis to form an effective air duct in the chassis, so that the wind entering the chassis only dissipates heat for the working circuit boards, and the empty slots need to be blocked. When the equipment is working, some square holes of the keel on the chassis need to be blocked. Fig.12 , Fig.15 As shown, there are 48 square holes 8-1 on the chassis keel 8: the front of the chassis is a horizontal horizontal card 10, each horizontal card corresponds to 6 square holes 8-1 on the keel; the rear of the chassis is a vertical cross card 11, each cross card corresponds to 8 square holes 8-1 on the keel. When the chassis equipment is fully equipped, the 8 horizontal cards 10 and the 6 vertical cards 11 are vertically orthogonally inserted in front and behind the keel 8, and the connectors of the front and rear cards pass through the corresponding square holes 8-1 on the keel. However, in actual work, the chassis equipment often does not work fully equipped. In this way, there will be empty square holes 8-1 on the keel. If it is not blocked, the wind entering the chassis will pass through the square hole 8-1, and the wind blowing to the two circuit boards will be reduced. In order to prevent this from happening, it is necessary to adopt a reasonable mechanical fixing method to block the square hole 8-1. Considering the situation of processing errors, it is necessary to design the baffle into a freely sliding structure to increase the reliability of assembly, facilitate production and assembly, and increase its practicality. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a windshield tray installed in a chassis, and the baffle is designed to be a freely slidable structure, which increases the reliability of assembly, facilitates production and assembly, and increases its practicability.

[0004] The technical scheme of the utility model is: a windshield tray for use in a chassis, comprising: a tray, a windshield plate and a positioning column; the tray comprises a tray, an air inlet plate arranged at the front end of the tray and assembly side plates arranged on the left and right sides of the tray, the tray is a rectangular plate, the two assembly side plates and the air inlet plate are vertically arranged on the three sides of the tray, and the rear end of the tray is open; six rows of positioning holes are arranged at the rear end of the tray, each row of positioning holes has two identical positioning circular holes, the position of each row of positioning holes is aligned with the square holes corresponding to the horizontal plug-in cards on the keel, and the center distance between the two positioning circular holes in each row of positioning holes is smaller than the center distance between the oblong holes on the horizontal fixing surface of the windshield plate; a track groove is arranged at the front end of the assembly side plate; the windshield plate comprises a horizontal fixing surface and a vertical windshield surface, the horizontal fixing surface and the vertical windshield surface are perpendicular to each other, an oblong hole is arranged on the horizontal fixing surface, the windshield plate is arranged at the rear end of the tray through the oblong hole and the positioning column, and the vertical windshield surface is close to the rear end of the tray; the height of the positioning column is greater than the thickness of the horizontal fixing surface of the windshield plate.

[0005] In the above technical solution, the number of wind shields at the front end of each tray is the number of columns of square holes of the keel minus the number of horizontal plug-in cards.

[0023] like Figures 1 to 15 As shown, a windshield tray for use in a chassis includes a tray 1, a baffle 2 and a positioning column 3;

[0024] The windshield 2 is made of insulating transparent plastic. The windshield 2 includes a horizontal fixing surface 2-1 and a vertical windshield surface 2-2. The horizontal fixing surface 2-1 and the vertical windshield surface 2-2 form an L shape. An oblong hole 2-3 is opened on the horizontal fixing surface 2-1. The area of ​​the vertical windshield surface 2-2 is slightly larger than the area of ​​the square hole 8-1 on the keel.

[0025] The total length of the oblong hole 2-3 is 15.5 mm, the length of the middle rectangle is 11 mm, and the distance between the center of the rear end of the oblong hole 2-3 and the vertical windshield surface 2-2 is 12 mm;

[0026] The tray 1 is made of a stainless steel plate, which is processed into a rectangular slot tray 1 through sheet metal. The rear end of the tray 1 is open, and several air inlets 1-6 are milled on the air inlet plate 1-2 at the front end of the tray 1. Track grooves 1-4 are milled at the front ends of the assembly side panels 1-3 on the left and right sides of the tray 1. Six rows of positioning holes are milled at the front end of the support plate 1-1 of the tray 1, and each group has two front-to-back aligned positioning circular holes 1-5.

[0027] The distance between the centers of the two positioning circular holes 1-5 is 8 mm, and the distance between the center of the rearmost positioning circular hole 1-5 and the rear end edge of the support plate 1-1 is 6.8 mm;

[0028] Each windshield 2 is arranged at the front end of the pallet 1-1 through the oblong hole 2-3 and the positioning column 3 in the following manner: first, fix the positioning column 3 to the positioning circular hole 1-5 of the pallet 1-1 with two countersunk screws 7, then put the oblong hole 2-3 on the horizontal fixing surface 2-1 of the windshield 2 on the two positioning columns 3, and then fix it with a gasket 4, a spring washer 5 and a nut 6. The height of the positioning column 3 is slightly higher than the thickness of the pallet 1-1 to ensure that the windshield 2 can slide smoothly on the pallet 1-1 through the oblong hole 2-3; the vertical windshield surface 2-2 of each windshield 2 on the assembled pallet 1 is aligned with the square hole 8-1 on the keel 8; at this time, the outer edge of the positioning column 3 is 1.65mm away from the outer edge of the arc of the oblong hole 2-3, the center of the positioning column 3 is 6.8mm away from the rear end edge of the pallet 1-1, and the vertical windshield surface 2-2 of the baffle 2 exceeds the rear end edge of the pallet 1-1 by 6.7mm;

[0029] The number of baffles 2 on the tray 1 is determined according to the number of horizontal plug-in cards 10 in the chassis, and the number of layers of the tray 1 is determined according to the number of vertical plug-in cards 11 in the chassis;

[0030] like Fig.11 , Fig.12 , Fig.13 As shown, the number of the horizontal plug-in cards 10 and the number of the vertical plug-in cards 11 are two each, so each tray 1 has four windshield plates 2, and six layers of trays 1 are inserted in the entire chassis;

[0031] After the windshield 2 is installed on the tray 1, the two form an assembly submodule, and then the assembly module is installed on the chassis along the track groove 1-4 at the front end of the assembly side plate 1-3, and fixed by the hand screws 12 on both sides of the tray 1; at this time, the distance between the rear edge of the tray 1-1 and the keel 8 is 6.54mm;

[0032] When the chassis is working, cold air is sucked in from the front end of the chassis through the air inlet 1-6, and becomes hot air after passing through the components in the chassis. The hot air is blown out from the rear end of the chassis by the fan in the chassis. The vertical windshield surface 2-2 of the baffle 2 is sucked by the fan 9 in the chassis, and the horizontal fixed surface 2-1 slides along the oblong hole 2-3. Since the vertical windshield surface 2-2 of the baffle 2 exceeds the rear end edge of the support plate 1-1 by 6.7mm, the distance between the rear end edge of the support plate 1-1 and the keel 8 is 6.54mm, and the length of the center distance between the middle of the oblong hole 2-3 is 3mm larger than the center distance between the two positioning columns 3, and the height of the positioning column 3 is higher than the thickness of the horizontal fixed surface 2-1 of the baffle 2, the vertical windshield surface 2-2 of the baffle 2 can easily slide onto the keel 8, thereby achieving the purpose of blocking the keel square hole 8-1.
