Problems solved by technology

[0006] However, this leads to a gap fit between the board and the guide rail, so that when the vehicle vibrates, it is very easy to form a fixed-amplitude vibration of the board, which in turn can easily cause damage to the chip of the board, open soldering of the solder joints, and damage to the overall equipment. Various defects such as increased noise
[0007] Especially for the long-span boards in the vehicle equipment, the above defects are more obvious

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] In order to effectively prevent boards, especially large-span boards in vehicle equipment from vibrating in the guide rails of the board slots, embodiments of the present invention provide a vibration damping device that can be installed in the extension path of several guide rails.

[0031] Please see first figure 1 , and combine Figure 2 to Figure 4 , the vibration damping device 1 provided by the embodiment of the present invention includes a bracket 10, wherein:

[0032] The bracket 10 has a bottom 11, the bottom 11 extends parallel to the bottom surface of the guide rail, and the inner surface of the bottom 11 is flush with the bottom surface of the guide rail;

[0033] The bracket 10 is also respectively formed with wall portions 12 on b...

Abstract

The invention provides a vibration damper for card-plugging boxes and a card-plugging box. The vibration damper provided by the invention is provided with spring pieces on both sidewalls of a support; contact parts of both spring pieces are located on the inner sides of the walls, so a card can be plugged into the gap between the contact parts of the two spring pieces; and supporting parts of the two spring pieces can resiliently support the contact parts with fixed parts as bearing points, so the supporting parts of the two spring pieces can resiliently damp vibratory shock applied on the card. Consequently, the vibration damper can effectively prevent the card, particularly a long-span card in a vehicle-mounted device, from vibrating in the track of the card-plugging box, and therefore various problems caused by vibration, such as the damage to card chips, the breaking of soldered dots and the increase of overall device noise, can be effectively reduced.

Description

technical field [0001] The invention relates to board card vibration reduction technology, in particular to a board card insertion box vibration damping device and a board card insertion box. Background technique [0002] With the perfect development of vehicles and transportation infrastructure, there are more and more types of on-board equipment. At present, common vehicle-mounted equipment mainly adopts single-board fastening type and multi-board plug-in type. Among them, the single-board fastening type has the characteristics of simple installation, strong overall rigidity, high natural frequency, but poor scalability; while the multi-board plug-in type has the characteristics of high scalability and flexible configuration. Therefore, according to the development trend of vehicle equipment, the multi-board plug-in type is more and more popular. [0003] The vehicle-mounted equipment adopting the multi-board plug-in type includes a board card slot box, and the board car...
