Abstract
The utility model discloses a controller sealing structure, which comprises an end cover (1), a box body casing (2), a screw (3) and a sealing strip (4). The end cover (1) is connected to the box body casing (2) through the screw (3), the end cover (1) is closely connected to the box body casing (2) on one side of the screw (3), a gap is arranged on the other side of the screw (3), and the sealing strip (4) is disposed in the gap. The thickness of the sealing strip (4) is bigger than the width of the gap, a corner is arranged on the sealing strip (4), a notch is arranged at the position of the corner, and gum is arranged on one side of the sealing strip (4) close to the box body casing (2). Due to the adoption of the special structural design of the sealing strip, the controller sealing structure has low production cost, good sealing performance and high electromagnetic interference shielding capability.
Description
Technical field
The utility model relates to a kind of controller hermetically-sealed construction.
Background technology
Because electric loop generally adds sealing gasket and just can satisfy the having relatively high expectations of housing waterproof in the electric motor car environment for use and safeguard that environment is all relevant with water, car.But electric motor car needs power battery pack power supply, and the electric current and voltage of motor regulates by the controller variable frequency control, and the switching frequency of controller internal power module is up to the 10k hertz, and electromagnetic interference is very serious; Simultaneously, the electromagnetic interference of outer bound pair controller is also very serious.Traditional controller can only satisfy higher water resistance mostly, can not satisfy the work requirements of controller for electric vehicle hermetically-sealed construction far away for the screening ability of electromagnetic interference.
The utility model content
The purpose of this utility model is to solve the deficiency of existing controller hermetically-sealed construction, and a kind of novel controller hermetically-sealed construction is provided, and overcomes that conventional seals structure production cost height, sealing are poor, shortcoming such as shield electromagnetic interference ability and complex structure.
The purpose of this utility model is achieved through the following technical solutions: the controller hermetically-sealed construction, it comprises end cap, casing body, screw and sealing strip, end cap is connected with the casing body by screw, end cap closely is connected with the side of casing body at screw, opposite side at screw is provided with the gap, sealing strip is arranged in the gap, and the thickness of sealing strip is greater than the width in gap.
Sealing strip described in the utility model is the plane sealing strip.
Sealing strip described in the utility model is provided with gum in the one side near the casing body.
On the sealing strip described in the utility model corner is arranged, the corner is provided with breach.
The breach angle of sealing strip described in the utility model equals the corner angle of sealing strip.
The beneficial effects of the utility model are:
(1) the casing body closely contacts with end cap, is equivalent to a totally enclosed cavity, and the performance of anti-electromagnetic interference is good, and electromagnetic radiation and leakage are very little;
(2) sealing strip is provided with gum, installs simple;
(3) sealing strip is a plane, good sealing effect, and sealing strip adopts exotic material, adapts to high-temperature work environment;
(4) the breach setting of sealing strip corner has guaranteed excellent sealing performance, and the sealing strip corner do not cut off, and sealing surface is continuous, good reliability, and production cost is low.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure, 1-end cap, 2-casing body, 3-screw, 4-sealing strip.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing: as shown in Figure 1, the controller hermetically-sealed construction, it comprises end cap 1, casing body 2, screw 3 and sealing strip 4, end cap 1 is connected with casing body 2 by screw 3, end cap 1 closely is connected with the side of casing body 2 at screw 3, opposite side at screw 3 is provided with the gap, and described gap comprises lateral clearance and axial clearance.Described sealing strip 4 is the plane sealing strip, is arranged in the gap, and the thickness of sealing strip 4 is greater than the width in gap, and this has guaranteed when trip bolt 3 can crush seal bar 4 and play the effect of sealing; Sealing strip 4 is provided with gum in the one side near casing body 2, sealing strip 4 is sticked on the casing body 2 to get final product when mounted, installs simple; Sealing strip 4 adopts exotic material simultaneously, adapts to high-temperature work environment.
Sealing strip 4 is provided with breach at its corner near casing body 2 places, and the breach angle equals the corner angle of sealing strip 4 and the corner angle between lateral clearance and the axial clearance.Does not cut off the corner, and the corner area of the sealing strip of not cutting off 4 is little, slightly perk when corner is extruded, but can be eliminated perk by self elasticity fully when compacted, can guarantee that like this sealing surface is continuous, smooth, favorable sealing property; If do not cut breach, the perk amplitude was big when corner was extruded, and can not flatten, and sealing effectiveness is poor; If cut off the corner of sealing strip 4 fully, not sealing of corner, sealing strip 4 is just discontinuous, just can not guarantee excellent sealing performance, if the corner sealing, after the adhesive curing, can follow the string in the gluing place, crimping is not tight, and dismoutability is poor.
Claims (5)
