Background
Electronic components in many devices and instruments generate a large amount of heat during operation, and the heat needs to be dissipated from the instruments as soon as possible, otherwise the instruments are overheated, damaged and even burnt. In the field of computers, automobile instruments, central control systems, and the like, in order to increase the heat dissipation speed, a heat dissipation fan is generally installed on a circuit board, and the heat is taken away by using the flowing air blown by the fan, so that the heat dissipation speed is increased. The existing cooling fan is generally locked on a circuit board through screws and then connected with a power supply through electric wires, but the installation of the screws requires that the circuit board has higher hardness on one hand and generates larger noise when the fan works on the other hand; moreover, the arrangement of the wires requires a certain wiring space to avoid affecting the work of the fan or other parts, and the installation of the screws and the connection of the wires are complicated, and the workload is large.
Disclosure of Invention
An object of the utility model is to provide a can convenient and fast ground install radiator fan on the circuit board to can reduce radiator fan's noise at work's mounting structure, improve radiator fan's the convenience of installing and removing in the time of the noise reduction.
The utility model discloses a radiator fan mounting structure on circuit board, including setting up in the installing support of circuit board one side, be equipped with the mounting groove that supplies radiator fan to put into on the installing support, radiator fan's side and the relative department in the mounting groove are provided with a plurality of mounting hole and locating hole sunken inwards respectively, radiator fan's mounting hole department installs the buffering cushion, the buffering cushion is protruding in radiator fan's side, the bulge diameter of buffering cushion is greater than the locating hole of installing support and partly stretches into in the locating hole; one side of the cooling fan adjacent to the circuit board is provided with an electric connection sheet, and an elastic connection elastic sheet is arranged on the circuit board opposite to the electric connection sheet.
The utility model discloses a radiator fan mounting structure on circuit board, install the buffering cushion in radiator fan's mounting hole, then insert the mounting groove of installing support together again, until the buffering cushion is relative with the locating hole in the mounting groove and partly stretch into the locating hole, at this moment, separated by the buffering cushion between radiator fan and the installing support, can form the buffering to the vibrations that the radiator fan produced in the work, also avoid radiator fan's vibrations to influence the work security of circuit board; in addition, after the cooling fan is inserted into the mounting groove of the mounting bracket, the electric connecting sheet on the cooling fan is in contact with the connecting elastic sheet on the circuit board to form electric connection, so that the cooling fan can replace the traditional electric wire and avoid the complicated operation caused by the installation of the electric wire; moreover, no matter the fixing of the cooling fan or the connection of the cooling fan and the circuit board, the cooling fan can be automatically inserted into the mounting groove, and the operation complexity is greatly reduced. Therefore, through the use of the cooling fan mounting structure, the mounting and dismounting convenience of the cooling fan can be effectively improved, and the working noise of the cooling fan is reduced, so that the comfort of the environment is improved.

Detailed Description
A cooling fan mounting structure on a circuit board comprises a mounting support 2 arranged on one side of the circuit board 1, wherein a mounting groove for placing a cooling fan 3 is formed in the mounting support, a plurality of mounting holes and positioning holes which are sunken inwards are formed in the side surface of the cooling fan and the corresponding position in the mounting groove respectively, a buffering rubber pad 7 is arranged at the mounting hole of the cooling fan, the buffering rubber pad protrudes out of the side surface of the cooling fan, the diameter of the protruding part of the buffering rubber pad is larger than that of the positioning hole of the mounting support, and the protruding part of the buffering rubber pad partially extends into the positioning hole; an electric connecting sheet 8 is arranged on one side of the heat radiation fan adjacent to the circuit board, and an elastic connecting elastic sheet 9 is arranged on the circuit board opposite to the electric connecting sheet.
The radiator fan mounting structure on the circuit board, the relative department with the mounting groove on installing support 2 is provided with the buckle that is used for fixed radiator fan 3, the end of buckle is provided with the location hook of card in the radiator fan side, when radiator fan inserted the mounting groove, the buckle was extruded by radiator fan and is produced deformation, until radiator fan inserts the back that targets in place, the buckle drives the location hook promptly and blocks in the radiator fan side to lock radiator fan. The structure is simple, but the installation strength of the cooling fan can be effectively improved.
The side of the heat radiation fan 3 is provided with a plurality of electric connection sheets 8 in parallel along the linear direction, and the circuit board 1 is correspondingly provided with a plurality of connection elastic sheets 9 with the same quantity. Through the connection of a plurality of electric connection pieces and the connection elastic sheet, the stability of electric connection can be ensured.
The part of buffering cushion 7 protrusion in radiator fan mounting hole is umbelliform structure, and the diameter at umbelliform edge is greater than the locating hole of installing support, and radiator fan and installing support can effectively be separated on the one hand to the part of this umbelliform, and on the other hand, the size at umbelliform top is less, can cooperate with the locating hole of installing support very conveniently, and it can stretch into in the locating hole through elastic deformation to realize location and fixed fast, accurately.
