Abstract
The utility model discloses a resistor self-heat dissipation connecting device comprising a PCB and a resistor disposed on the PCB. The resistor is electrically connected with the PCB through an external heat dissipation device, which is covered on the resistor. The heat dissipation device can be used to facilitate the heat dissipation of the resistor on the PCB, and the installation of the resistor can be facilitated.
Description
Technical field
The utility model relates to power source products heat radiation field, relates in particular to a kind of resistance from dispelling the heat jockey.
Background technology
At present, to the thermal stress requirement increasingly stringent of power supply, power supply need be accomplished effective heat radiation, and particularly some power resistors can't be accomplished good heat radiation.
General design is to be installed on the pcb board resistance is unsettled, or with resistance be close to pcb board on, the former dispels the heat by flow air, the latter accomplishes heat radiation by pcb board.
As shown in Figure 2, during actual production, earlier by resistance 2 is directly inserted and pcb board 1 on, mainly be the height of adjusting resistance 2, and weld resistance 2 again after keeping certain height.When atmosphere draught-free, resistance is difficult to effectively heat radiation, can't accomplish the effect of dispelling the heat.When welding, because of the bad control of the height of power resistor, so be welded with certain degree of difficulty, installation effectiveness is produced in influence.
If adopt resistance 2 is close to this mounting means on the pcb board 1, easily pcb board is damaged and also radiating effect poor.
The utility model content
The purpose of this utility model is the defective that exists at above-mentioned prior art, proposes a kind of resistance from dispelling the heat jockey.
The technical solution adopted in the utility model is, designs a kind of resistance from dispelling the heat jockey, comprising: pcb board and be installed in resistance on the pcb board, described resistance is electrically connected with described pcb board by covering in its outside radiator.
In one embodiment, described radiator is made up of the upper and lower, and forms the cavity structure that is sticked in described resistance, described top comprises a web and is connected in the clip at web two ends, two clip lateral symmetry arrange, and clip one end is connected with web, and the other end is provided with opening; Described bottom is frame shape and is plugged on the described pcb board, and the pin of described resistance one end is welded in pcb board, the pin of the other end and the welding hole welding of being located at described web.
Also be provided with a pair of louvre on the described web.
Described radiator adopts aluminium or ferrous metal material to make.
Compared with prior art, the radiator cover that the utility model adopts is on the resistance on the pcb board, the easy conductive heat conductive metal material that radiator adopts, when resistance is worked, the absorption resistance heat, the heat radiation of help resistance, solve the problem of traditional design method weak heat-dissipating, and pin and the radiator of resistance one end welded, made things convenient for the installation of resistance, whole is simple in structure, simple installation.
Description of drawings
Fig. 1 is scheme of installation of the present utility model;
Fig. 2 is the scheme of installation of prior art.
Embodiment
Below in conjunction with drawings and Examples utility model is described in detail.
As shown in Figure 1, the resistance that the utility model proposes comprises from dispelling the heat jockey: pcb board 1, resistance 2 and radiator 3, wherein, radiator 3 adopts aluminium or ferrous metal material to make, it covers in the outside of resistance 2, and radiator 3 is made up of the upper and lower, and it is inner to form a cavity structure that is sticked in described resistance 2, top comprises the clip 7 that a web 6 is connected with the web two ends, the 7 lateral symmetry settings of two clips, clip 7 one ends are connected with web, and the other end is provided with opening; Belly 6 is provided with welding hole and a pair of louvre 8.The bottom of radiator 3 is frame shape, the plug that many installation usefulness are stretched out in the framework bottom is plugged on the pcb board 1, has realized being electrically connected of pcb board and radiator 3.
Produce when installing, elder generation packs resistance 2 in the radiator 3, and being welded on the welding hole 5 on the radiator 3 the pin of resistance 2 upper ends, pin with resistance 2 lower ends is welded on the pcb board 1 then, at last radiator is inserted on the pcb board, make because radiator 3 adopts conductive metallic materials, namely realized being electrically connected of resistance 2 and pcb board after the installation.This kind connected mode has solved the problem that the resistance of conventional art is inconvenient to install, treat resistance work adstante febre, radiator 3 carries out mutual heat exchange with resistance 2, effectively reduces resistance 2 temperature, and be not subjected to the influence of the mobile speed of air, and also can not cause the hidden danger of damage to pcb board.
Above-described embodiment only is used for explanation embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and variation, these distortion and variation all should belong to protection range of the present utility model.
Claims (4)
1. a resistance is from dispelling the heat jockey, comprises pcb board (1) and is installed in resistance (2) on the pcb board, it is characterized in that described resistance (2) is electrically connected with described pcb board (1) by covering in its outside radiator (3).
