Abstract
The utility model provides a kind of electronic device mounting structure of frequency converter, comprising: circuit board, circuit board is provided with the conductive through hole for mounting electronic device; Screw rod, one end is connected with circuit board, and the other end is connected with electronic device; Conductive and heat-conductive copper pipe, is enclosed within the outside of screw rod, and conductive and heat-conductive copper pipe is clamped between circuit board and electronic device.Compared with prior art structure is more simple, cost is lower for the utility model, and to employee without other requirements, owing to installing the wrongly installed damage causing electronic device of lamination copper coin by mistake, can not also improve radiating effect.
Description
Technical field
The utility model relates to frequency converter field, particularly a kind of electronic device mounting structure of frequency converter.
Background technology
Frequency changer controller is made up of two necessary parts usually: one is the electrochemical capacitor of filtering, and two is IGBT module of alternating current direct current being changed into various frequency.Due to the line inductance in device will be reduced, usually adopt positive and negative lamination copper coin structure when electric capacity and the positive and negative end of IGBT module are drawn, lamination copper coin of the prior art is to adopt as shown in Figure 1 direct in lamination copper coin punching press step connected mode with electric capacity or IGBT module joint.As shown in Figure 1, circuit board 1 is formed with punching press step 10, electronic device 2 is arranged on punching press step 10 place by lock-screw 11.Wherein, electronic device 2 is electric capacity or IGBT device.
But this mode can cause the more complicated insulating process of positive and negative electrode and material, dispel the heat bad and insulation costs of lamination copper coin is caused significantly to increase, secondly the screw length of joint should not also be controlled, particularly IGBT module has requirement to screw length, and long meeting causes IGBT module to damage because withstanding chip in IGBT module.Finally be not easy to the installation of the inner detection line of joint frequency converter.
Utility model content
The utility model provides that a kind of structure is simple, cost is low, good heat dissipation effect, can not because installing the electronic device mounting structure of the frequency converter that cause electronic device to damage.
For solving the problem, as an aspect of the present utility model, providing a kind of electronic device mounting structure of frequency converter, comprising: circuit board, circuit board being provided with the conductive through hole for mounting electronic device; Screw rod, one end is connected with circuit board, and the other end is connected with electronic device; Conductive and heat-conductive copper pipe, is enclosed within the outside of screw rod, and conductive and heat-conductive copper pipe is clamped between circuit board and electronic device.
Preferably, electronic device is electric capacity or IGBT device.
Preferably, one end of screw rod is connected with circuit board by clamp nut.
Preferably, the other end of screw rod is threaded with electronic device.
Preferably, the external diameter of conductive and heat-conductive copper pipe is 15mm.
Preferably, the middle part of screw rod is polished rod.
Owing to have employed technique scheme, compared with prior art structure is more simple, cost is lower for the utility model, and to employee without other requirements, owing to installing the wrongly installed damage causing electronic device of lamination copper coin by mistake, can not also improve radiating effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 2, the utility model provides a kind of electronic device mounting structure of frequency converter, comprising: circuit board 1, circuit board 1 is provided with the conductive through hole for mounting electronic device 2; Screw rod 4, one end is connected with circuit board 1, and the other end is connected with electronic device 2; Conductive and heat-conductive copper pipe 5, is enclosed within the outside of screw rod 4, and conductive and heat-conductive copper pipe 5 is clamped between circuit board 1 and electronic device 2.Preferably, electronic device 2 is electric capacity or IGBT device.Preferably, the external diameter of conductive and heat-conductive copper pipe 5 is 15mm, and like this, the external diameter of conductive and heat-conductive copper pipe 5 is less than the external diameter 28mm of punching press step of the prior art, thus increases creepage distance 3.
Circuit board 1 comprises insulating trip 8 and is positioned at the copper sheet 7 of insulating trip 8 both sides, and wherein, insulating trip 8 is electrically connected with electronic device 2, and can dispel the heat to electronic device 2.Conductive and heat-conductive copper pipe 5 pairs of electronic devices 2 dispel the heat, and also play the effect be connected of electronic device 2 and copper sheet 7 being conducted electricity simultaneously.Electronic device 2, circuit board 1 and conductive and heat-conductive copper pipe 5 are connected into an entirety by screw rod 4.
Preferably, one end of screw rod 4 is connected with circuit board 1 by clamp nut 6.
Preferably, the other end of screw rod 4 is threaded with electronic device 2.
Preferably, the middle part of screw rod 4 is polished rod.Like this, can prevent screw rod 4 from screwing in the excessively dark problem of electronic device 2, adopt substep to install, facilitate the installation of the inner detection line 9 of joint frequency converter, prevent vision blind spot.
Owing to have employed technique scheme, the utility model compared with prior art cost is lower, and to employee without other requirements, can not owing to installing the wrongly installed damage causing electronic device of lamination copper coin by mistake.In addition, detect through temperature device, the utility model good heat dissipation effect, its temperature 5 to 7 degree lower than the temperature of prior art.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
