Waterproof box power cord waterproof structure

This creation is a waterproof structure of a waterproof box power cord, especially a waterproof structure of a waterproof box for a circuit breaker.

At present, various waterproof boxes are sold on the circuit breakers for installation on circuit breakers. The general circuit breakers are used to protect electrical appliances. In order to avoid excessive current flow caused by electrical appliances, damage or wire fire may occur. The circuit breaker needs to be installed in an outdoor or humid environment, that is, the circuit breaker may not work properly or even be damaged due to water or humid air. Therefore, in the above environment, a waterproof box is usually installed outside the circuit breaker. In the conventional structure, refer to the structure of the waterproof case 90 for a circuit breaker as shown in Fig. 5, in which one side has a wire hole 91 through which the power supply line 92 passes, and at the outlet hole 91 only the bolt head 93 is used. And the nut 94 or the filling glue to fix the power cord 92, can not achieve the prevention of moisture intrusion; at the same time, the power cord 92 is twisted into a multi-core twisted wire by the copper core body 95, as shown in Fig. 6, the water vapor and the moisture are also It will enter through the exposed contact surface, and it will not be able to achieve the effect of blocking the moisture and moisture from entering the connected circuit breaker via the power line 92.

In view of the problems encountered in waterproofing the waterproof power cord of the waterproof box, the main purpose of the present invention is to provide a waterproof structure of the waterproof box of the waterproof box for providing the circuit breaker.

According to the embodiment of the present invention, the waterproof case comprises a box body, a cover body, a metal wire and a sealant, wherein the side of the case body has an outlet port, and the metal wire is, for example, a plurality of metal wires, and the metal wires are all self-exiting The wire mouth is pierced out of the box body, and the metal wires correspond to the position of the outlet port, and have a deformation portion, and the above-mentioned sealant is sealed at the outlet port and simultaneously sealed in the deformation portion, except In addition to the purpose of fixing, the sealing effect is further provided; in addition, these metal wires have a covering body, and when assembled on the waterproof case, the covering body does not cover the deformation portion, and only covers other parts of the metal wire. The deformation portion in this embodiment is formed by extruding a metal wire, that is, extruding a copper core in the electric wire to deform it to block moisture and moisture.

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a perspective view of an embodiment of the present waterproof case, and FIG. 2 is an exploded view of the foregoing embodiment. As shown in the figure, the waterproof case of the present embodiment includes a case. 10. The cover body 30, the metal wire 40 and the sealant 50, wherein the side of the case body 10 has an outlet port 13; the cover body 30 is closed on the case body 10 to form a closed space to prevent moisture and moisture from entering.

Please refer to FIG. 3 and FIG. 4, FIG. 3 is a schematic view of the metal wire of the present invention, and FIG. 4 is a schematic view of the metal wire after the deformation of the created metal wire, and as shown in the figure, in the embodiment of the present invention, In this embodiment, the metal wire 40 is, for example, a plurality of metal wires 40, that is, a plurality of copper cores, and the metal wires 40 are all threaded out of the wire box 13 out of the casing 10, and the metal wires 40 correspond to the metal wires 40. At the position of the wire opening 13, there is a deformation portion 41, and the above-mentioned sealant 50 is sealed at the outlet port 13 and simultaneously sealed in the deformation portion 41, and further has a seal in addition to the purpose of fixing. The metal wire 40 has a covering body 42. In the embodiment, when the metal wire 40 is assembled on the casing 10, the covering body 42 is not covered by the deformation portion 41, and only covers the metal wire 40. In other parts, further, in the present embodiment, the deformation portion 41 is formed by pressing the metal wire 40, that is, extruding the copper core in the electric wire to deform it to block moisture and moisture from passing through the power line covering body 42. And the core gap enters to achieve the effect of double barrier .

Although the present invention has been disclosed above in the preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art will not depart from the present invention. Within the spirit and scope, some changes and refinements can still be made. Therefore, the scope of protection of this creation is subject to the definition of the patent application scope attached.
