Description

Technical Field

[0001] The utility model relates to the field of power switch boxes, and particularly relates to a waterproof device for a power switch box. Background Art

[0002] The power switch box is mainly used to control the connection of the power supply. The existing power switch box generally includes a housing, a power module, a switch and a socket accommodated inside the housing. With the enrichment of application scenarios, the performance requirements of the power switch box have also been improved. For example, when used in a humid environment, it needs strong waterproof performance. However, the existing power switch boxes often do not have any waterproof function. Long-term use in a humid environment will cause water vapor to invade and damage the power module arranged inside the housing. Moreover, it will also be eroded by dust or other impurities, bringing serious safety hazards to the use of the power switch box and shortening the service life of the power switch box. To solve the above problems, a waterproof device for a power switch box is specifically proposed. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a waterproof device for a power switch box with a simple structure, convenient use and reliable waterproof performance.

The switch box body is provided with a button hole. A switch assembly corresponding to the button hole is further arranged inside the switch box body. An isolation member with elastic deformation ability is arranged between the switch box body and the switch assembly. The isolation member is used to seal the button hole.

[0005] Preferably, the isolation member includes a pressing part corresponding to the switch assembly and a sealing edge. The pressing part and the sealing edge are integrally formed. The advantage is that the integrity of the isolation member can be ensured through the integrally formed pressing part and sealing edge, and thus the reliability of the seal can be ensured.

[0006] Furthermore, the switch box body is provided with a pressing part, and the pressing part is in sealing fit with the isolation member. The advantage is that the isolation member can be better pressed through the arranged pressing part, and thus the sealing effect of the isolation member on the button hole can be ensured.

[0007] Furthermore, a sealing sleeve is arranged on the peripheral side of the sealing edge, and the sealing sleeve is sleeved outside the pressing part. The benefit is that the sealing performance of the isolation member can be further improved through the cooperation of the arranged sealing sleeve and the pressing part, and water stains can be prevented from penetrating into the switch box body.

[0008] Furthermore, the switch assembly includes a switch body and a mounting plate. The switch body is disposed on the mounting plate. The mounting plate is detachably engaged with the switch box body, and the mounting plate presses the separator; the advantage is that the detachable mounting plate can more reliably press the separator and is convenient for replacement and maintenance.

[0009] Furthermore, the switch assembly further includes a cover plate. The cover plate is located between the separator and the mounting plate, and the cover plate is fitted with the sealing edge. The switch body passes through the cover plate and extends into the pressing portion; the advantage is that the cover plate provided can isolate the connecting wires of the switch body. At the same time, the fitting of the cover plate and the sealing edge can better ensure the flatness of the sealing edge, reduce the damage caused by deformation, that is, avoid the pulling deformation and breakage between the pressing portion and the sealing edge, thereby improving the service life of the separator.

[0010] Furthermore, a plurality of fixing posts are provided on the periphery of the separator inside the switch body. The fixing posts are detachably provided with fixing bolts, and the fixing bolts are used to press the mounting plate and the cover plate; the advantage is that the cooperation of the fixing posts and the fixing bolts provided can reliably ensure the fixing of the mounting plate and the cover plate to the separator, thereby improving the sealing performance and assembly convenience.

[0011] Furthermore, corrugated grooves are provided on the periphery of the pressing portion; the advantage is that the corrugated grooves provided can ensure that the pressing portion deforms along a fixed direction when being squeezed, thereby ensuring its elasticity and use reliability and extending the service life.

[0012] Furthermore, a key cap is movably disposed inside the switch box body in the button hole, and the pressing portion is embedded in the key cap; the advantage is that the key cap provided facilitates the user to press the switch assembly to control the power supply, and at the same time, it can prevent foreign objects from entering the button hole, thereby reducing the damage of foreign objects to the separator.

[0013] Furthermore, a plurality of guiding ribs are provided on the side wall of the button hole. The key cap is provided with a fixing edge, and a limiting groove matching with the guiding ribs is provided on the fixing edge. The switch box body is further provided with an anti-detachment edge corresponding to the fixing edge; the advantage is that the cooperation of the guiding ribs and the limiting groove provided can ensure the smooth pressing of the key cap, and at the same time, the anti-detachment edge provided can prevent the key cap from coming out of the button hole and ensure the use reliability.
