Embodiment
With reference to Fig. 1, Fig. 1 is the structure chart of AC motor control 1.AC motor control 1 comprises pedestal 11 and cover 12, and cover 12 covers above pedestal 11, and five waterproof jackets 2 and an Insurance Block 13 are installed on cover 12.With reference to Fig. 2, Fig. 2 is the exploded view of AC motor control 1, pedestal 11 is formed with cavity 111 with caving inward, in cavity 111, control unit is installed, control unit comprises power cell, power amplifier board, is arranged on three binding posts 31 on power cell and is arranged on two binding posts 32 on power amplifier board, power cell is arranged on the base plate of pedestal 11, and power amplifier board is arranged on the top of power cell.Power cell comprises a substrate, and substrate is provided with power module assembly, and power module assembly comprises anodal DC power supply terminal, negative pole DC power supply terminal, power model and three binding posts 31, and power model is comprised of electronic devices such as a plurality of thyristors.Power amplifier board comprises substrate, and two binding posts 32, controllable switch components 112, power amplifier board assembly 113 and driver module are installed on the substrate of power amplifier board, and driver module comprises that 14, three Hall elements 14 of three Hall elements are enclosed within respectively outside three binding posts 31.Cover 12 offers five through holes 123 on the position of corresponding binding post 31 and binding post 32, and the periphery along through hole 123 on cover 12 is formed with bulge loop 121, at the inwall of through hole 123, is inwardly formed with inner shoulder table 122.
With reference to Fig. 3 and Fig. 4, waterproof jacket 2 is made by rubber-like or TPO elastomeric material, waterproof jacket 2 is formed with through hole 21 vertically, on through hole 21 one end toward the outer side, there is end face 211, waterproof jacket 2 has closure gasket groove 23 in through hole 21 arranged outside, and the opening of closure gasket groove 23 arranges towards inner side.Between through hole 21 and closure gasket groove 23, be formed with bulge loop 22, have end face 221 at bulge loop 22 on one end of inner side, at the dorsal part of closure gasket groove 23, have end face 231, closure gasket groove 23 is surrounded by bulge loop 22 and ring wall 24.Between end face 211 and end face 231, be provided with joint face 25, joint face 25 along peripheral, oblique arrange, in end face 231 outermost end along being circumferentially provided with inclined plane 26.
With reference to Fig. 5 and Fig. 6, Fig. 5 is the vertical view of AC motor control, Fig. 6 be Fig. 5 at the cutaway view of A-A position, be positioned at the cutaway view at binding post 31 places.Cover over there 12 install before, first waterproof jacket 2 is arranged on through hole 123, be about to bulge loop 22 and be installed in through hole 123, annular groove 23 is sleeved on bulge loop 121, now bulge loop 22 not with through hole 123 interference fit.Subsequently the cover 12 of the good waterproof jacket 2 of pre-installation is installed to the upper of pedestal 11, binding post 31 reaches outside cover 12 through inner shoulder table 122, through hole 21 successively, and binding post 31 is formed with screens platform 31 vertically, and screens platform 31 coordinates with inner shoulder table 122.Because waterproof jacket 2 is to be made by elastomeric material, and the through hole 21 of waterproof jacket 2 non-be subject to external force in the situation that its radius be the radius that is less than binding post 31, binding post 31 is through after through hole 21, under the effect of binding post 31, waterproof jacket 2 and binding post 31 interference fit, the bulge loop 22 of waterproof jacket 2, to surrounding expansion, makes the end face interference fit of bulge loop 22 and through hole 123 inwalls, inner shoulder table 122 simultaneously.Preferably, the radius of inner shoulder table 122 is arranged to be less than to the radius of binding post 31, is conducive to improve the tolerance between assembly parts, more easy while making to assemble.
As seen from Figure 6, end face 211 is greater than end face 231 apart from the height L2 of cover 12 apart from the height L1 of cover 12, is greater than the setting of L2 by L1, and water droplet can top-downly be departed from, and avoids the formation of ponding.The height L4 of bulge loop 22 is greater than the height L3 of ring wall 24, by having the bulge loop 22 and through hole 123 interference fit of high height, can improve sealing property.
Certainly, what above-described embodiment was told about is that waterproof jacket 2 is sleeved on principle and the process on binding post 31, because binding post 31 and binding post 32 have same structure feature, and the through hole 123 that cover 12 arranges is all identical, so waterproof jacket 2 uses same principle and method can be sleeved on binding post 32.
Therefore, by inner shoulder table 122 and through hole 21, be sleeved on binding post 31 or binding post 32, because waterproof jacket is made by elastomeric material, so after waterproof jacket and binding post interference fit, along with waterproof jacket expands outwardly, waterproof jacket with through hole 123 inwalls, inner shoulder table 122 interference fit, and be enclosed within outside bulge loop 121 by closure gasket groove 23, make this waterproof jacket can effectively prevent that outside steam from entering in AC motor control, by thering is flexible waterproof jacket, can simplify the sealing process of binding post simultaneously, improve production and processing efficiency.
