The utility model provides a shielding structure of a high-voltage part.
Referring to fig. 1 to 4, in the embodiment of the present invention, the high voltage part shielding structure includes a high voltage part housing 10, a high voltage insert 20, and a crimping piece 30. The high-voltage part shell 10 is provided with a through hole 11, specifically, the high-voltage part can be a high-voltage part such as an electric drive system, a charger, a power converter, an electric heater, an air conditioner compressor or a high-voltage battery in a vehicle, the high-voltage part is provided with a shell, and the high-voltage part shell 10 is made of metal materials so that electromagnetic noise can be grounded through the high-voltage part shell 10. Through-holes 11 are opened therein to allow the high-voltage inserts 20 to pass therethrough.
The high-voltage plug-in 20 is plugged with a high-voltage cable 21, the outer peripheral wall of the high-voltage cable 21 is provided with a shielding layer 22, and the high-voltage plug-in 20 is inserted into the high-voltage shell 10 through the through hole 11. The shielding layer 22 is a metal braid or an aluminum foil loop conductor for preventing the line from radiating electromagnetic energy to the outside, and has the function of reducing the influence of an external electromagnetic field on the power supply or the communication line, specifically, the function of isolating the electromagnetic field noise source from the sensitive equipment and cutting off the propagation path of the noise source. The shielding layer 22 needs to be grounded, and its own interference energy and external interference signals can be guided to the ground by the shielding layer 22, so as to avoid the interference signals entering the inner conductor to interfere and avoid the noise generated by the high voltage element itself from affecting other devices. The high-voltage part housing 10 is provided with a through hole 11, and the through hole 11 is sized to receive the high-voltage insert 20 therethrough, so that the high-voltage insert 20 is inserted into the high-voltage part housing 10. In one embodiment, the size of the through hole 11 is adapted to the outer circumference of the high voltage insert 20, that is, the through hole 11 is just penetrated by the high voltage insert 20, and the inner wall of the through hole 11 contacts the outer circumference wall of the high voltage insert 20, that is, the high voltage part housing 10 contacts the shielding layer 22 at the outer circumference wall of the high voltage insert 20, so that part of the contacts on the shielding layer 22 contacts the high voltage part housing 10 through the inner wall of the through hole 11, and thus part of the electromagnetic waves on the shielding layer 22 cause the grounding through the high voltage part housing 10. Here, the size and shape of the through hole 11 are not limited as long as it can pass the high pressure insert 20 to be inserted into the high pressure housing 10.
The crimping piece 30 is fixed to the inside of the high-voltage element case 10, and is provided with a shaped hole 31 for accommodating the high-voltage cable 21, and the inner wall of the shaped hole 31 is in conductive contact with the shield layer 22 in the circumferential direction of the high-voltage cable 21. Specifically, the crimping pieces 30 are located inside the high-voltage part housing 10, and after the high-voltage insert 20 is inserted into the high-voltage part housing 10 through the through hole 11, the crimping pieces 30 are crimped to the high-voltage insert 20, and the crimping pieces 30 abut against the inner wall of the high-voltage part housing 10. The crimping piece 30 is provided with a shaped hole 31, and the size and shape of the shaped hole 31 are matched with those of the high-voltage insert 20, so that after the crimping piece 30 is crimped on the high-voltage insert 20, the inner peripheral wall of the shaped hole 31 is completely contacted with the outer peripheral wall of the high-voltage insert 20, even if the inner wall of the shaped hole 31 is completely contacted with the shield contact in the circumferential direction of the high-voltage insert 20. The pressing piece 30 is made of metal, such as iron or copper, so that the electromagnetic noise can be grounded through the pressing piece 30. The electromagnetic noise is transmitted from the shield contact to the crimping piece 30 through the irregularly shaped hole 31, and then grounded through the high-voltage element case 10 abutting against the crimping piece 30. In one embodiment, the high-voltage housing 10 contacts the shielding layer 22 of the high-voltage insert 20 through the through hole 11, and the press-contact piece 30 contacts the shielding layer 22 of the high-voltage insert 20 through the shaped hole 31. At this time, the electromagnetic noise may be transmitted from the shield contact to the high-voltage element case 10 through the through hole 11 to be grounded, and may be transmitted from the shield contact to the crimping piece 30 through the special-shaped hole 31 to be grounded through the high-voltage element case 10 abutting against the crimping piece 30.
In one embodiment, when the high voltage shielding structure is used, the high voltage insert 20 is inserted into the high voltage housing 10 from the outside of the high voltage housing 10 through the through hole 11, and the inner wall of the through hole 11 is contacted with a part of the shielding layer contact of the high voltage cable 21; sleeving the crimping piece 30 on the high-voltage plug-in 20 from the inner side of the high-voltage piece shell 10, and enabling the special-shaped hole 31 of the crimping piece 30 to be in complete contact with the shielding layer contact of the high-voltage cable 21; the press contact piece 30 is fixed on the high-voltage part housing 10 in an abutting manner, so that a high-voltage part shielding structure in which the press contact piece 30, the high-voltage insert 20 and the high-voltage part housing 10 are connected is realized. Thus, the electromagnetic noise can be grounded through the high-voltage housing 10 connected to the shield contact, and also through the crimping piece 30 connected to the shield contact, and further through the high-voltage housing 10 abutting against the crimping piece 30. The electromagnetic noise can be directly grounded through the high-voltage part shell 10 without affecting the original grounding effect of the grounding contact of the shielding layer 22, and meanwhile, the electromagnetic noise can be grounded through the compression joint sheet 30 and the high-voltage part shell 10, so that the shielding effect of the high-voltage plug-in 20 is improved.
One technical scheme of the utility model is that the crimping piece 30 is arranged in the high-voltage part shielding structure, so that the special-shaped hole 31 of the crimping piece 30 is in contact with the shielding layer contact of the high-voltage cable 21 on the high-voltage insert 20. When the high-voltage part shielding structure is used, the high-voltage plug-in 20 is inserted into the high-voltage part housing 10 through the through hole 11 on the high-voltage part housing 10, and then the press-connection piece 30 is sleeved on the high-voltage plug-in 20 from the inner side of the high-voltage part housing 10, so that the inner wall of the special-shaped hole 31 on the press-connection piece 30 is in contact with all the shielding layer contacts of the high-voltage cable 21, and the press-connection piece 30 is in butt joint with and fixed on the inner side of the high-voltage part housing 10. In this way, the electromagnetic noise of the high-voltage cable 21 can be transmitted from the shielding layer 22 to the high-voltage part housing 10 through the through hole 11 to be grounded, and can be transmitted from the shielding layer 22 to the crimping piece 30 through the special-shaped hole 31 to be grounded through the high-voltage part housing 10 in contact with the crimping piece 30. Compared with the scheme that the electromagnetic noise is grounded only through the high-voltage part shell 10 without the arrangement of the contact sheet 30, the grounding device provided by the utility model can be used for grounding the electromagnetic noise through the compression joint sheet 30 and the high-voltage part shell 10 while not influencing the grounding effect of the grounding contact of the original shielding layer 22, so that the shielding effect of the high-voltage plug-in unit 20 is improved.
Further, the high-voltage cable 21 includes the anodal high-voltage line 211 and the negative pole high-voltage line 212 that set up side by side, and the periphery wall of anodal high-voltage line 211 and negative pole high-voltage line 212 all is equipped with shielding layer 22, is equipped with two dysmorphism holes 31 on the crimping piece 30 to make the inner wall in a dysmorphism hole 31 and the shielding layer 22 of anodal high-voltage line 211 laminate completely, the inner wall in a dysmorphism hole 31 and the shielding layer 22 of negative pole high-voltage line 212 laminate completely. Specifically, the high-voltage cable 21 includes a positive high-voltage wire 211 and a negative high-voltage wire 212, and correspondingly, two special-shaped holes 31 are provided in the pressing piece 30, so that the positive high-voltage wire 211 and the negative high-voltage wire 212 respectively pass through one special-shaped hole 31, and all the shielding layer contacts on the positive high-voltage wire 211 are in contact with the inner wall of one special-shaped hole 31, and all the shielding layer contacts on the negative high-voltage wire 212 are in contact with the inner wall of the other special-shaped hole 31. In the scheme shown in the figures of the present invention, the special-shaped hole 31 is zigzag to be completely attached to the outer wall of the positive high-voltage wire 211 and the outer wall of the negative high-voltage wire 212, and the shape and size of the special-shaped hole 31 are not limited herein as long as it can be completely attached to the circumferential direction of the positive high-voltage wire 211 and the circumferential direction of the negative high-voltage wire 212. Compared to the prior art in which the crimping piece 30 is not provided and the electromagnetic noise is grounded only through the high voltage housing 10, in the prior art, only one side of the high voltage cable 21 facing the through hole 11 may contact the inner wall of the through hole 11 to ground the electromagnetic noise through the high voltage housing 10. However, the side of the positive high-voltage wire 211 close to the negative high-voltage wire 212 and the side of the negative high-voltage wire 212 close to the positive high-voltage wire 211 cannot be in contact with the inner wall of the through hole 11 of the high-voltage housing 10, that is, in the prior art, the shield contacts on the opposite sides of the positive high-voltage wire 211 and the negative high-voltage wire 212 cannot be in contact with the high-voltage housing 10, and thus, the electromagnetic noise of the parts cannot be effectively grounded. According to the utility model, the special-shaped holes 31 which are completely attached to the shielding layer 22 of the anode high-voltage wire 211 and the shielding layer 22 of the cathode high-voltage wire 212 are arranged on the crimping pieces 30, so that the contacts on the shielding layer 22 of the high-voltage cable 21 are completely grounded, and the shielding effect of the high-voltage plug-in 20 is improved. Meanwhile, the grounding effect of the original grounding contact of the shielding layer 22 is not influenced, and the grounding device is simple in structure and convenient to use.
Further, the high voltage insert 20 is inserted with the interlocking wire 23, and the crimping piece 30 is further provided with a receiving hole 32 for receiving the interlocking wire 23 through the crimping piece 30. Specifically, interlocking line 23 leads to 12V level, if the pencil that high-voltage plug-in components 20 connects is pulled out by the manual work, then the 12V level can not be detected to the controller, judges that the electrified position of high voltage system is naked hourglass, has the risk of electrocuteeing, and the controller control high-voltage power off this moment, so, the position of being pulled out by the manual work does not take high-voltage electricity, guarantees safety. The interlocking wire 23 on the high-voltage plug-in 20 ensures the normal use of the high-voltage element and the use safety of the high-voltage element. Correspondingly, the crimp piece 30 is provided with a receiving hole 32 for receiving the interlock wire 23, so that the crimp piece 30 can pass through the high-voltage cable 21 and the interlock wire 23 when the high-voltage insert 20 is sleeved on the crimp piece 30. Further, the accommodation hole 32 communicates with the two shaped holes 31. Thus, the press-contact piece 30 can be easily formed. It is worth noting that the accommodation holes 32 communicate with the two profiled holes 31 on the premise that all the contacts of the shielding layer 22 of the high voltage cable 21 are ensured to be in contact with the profiled holes 31, thereby ensuring that all the contacts of the shielding layer 22 are grounded.
