Description

Technical Field

[0001] The utility model relates to the technical field of waterproofing for distribution interfaces, and particularly to a waterproof plug for a distribution control device. Background Technique

[0002] A waterproof plug is a connecting device often used in the power system, mainly applied to outdoor products, medium and large-sized control machinery, equipment with an outdoor control system not on the main body, such as chemical plants, power plants, power supply bureaus, base stations of telecommunication networks, and factories with a relatively high degree of automation. Waterproof plugs are required in all these cases. However, the existing waterproof plugs have relatively limited waterproof performance, are easily invaded by water, thus limiting their stability and applicability in use. Moreover, the firmness of the connection between the plug and the socket is poor, and the plug is easily detached from the socket. For this reason, we propose a waterproof plug for a distribution control device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waterproof plug for a distribution control device, which solves the problems in the background technique.

[0005] The waterproof fixing mechanism includes a waterproof cover and a pin plate. The waterproof cover is fixedly installed on the outer wall of the plug body. A waterproof groove is opened on the left side of the socket. The waterproof cover is inserted into the waterproof groove. A contraction groove is opened on the inner wall of the waterproof groove. The pin plate is inserted into the contraction groove. A pin slot is opened on the outer wall of the waterproof cover. The pin plate is inserted into the pin slot. A pull handle is fixedly installed on the front surface of the pin plate. A handle groove is opened on the left side of the socket and communicates with the contraction groove. The pull handle movably penetrates through the handle groove. A groove pad is fixedly installed on the inner wall of the contraction groove. The groove pad is in close contact with the outer wall surface of the pin plate.

[0006] Preferably, the waterproof cover is in an umbrella shape and is adapted to the waterproof groove. By setting the waterproof cover in an umbrella shape, it can play a good role in guiding and blocking water droplets.

[0007] Preferably, the pin plate is adapted to the pin slot and the contraction groove, and the pull handle is adapted to the handle groove. By setting the pull handle, it is convenient for personnel to pull the pin plate through the pull handle, thus facilitating operation by personnel.

[0008] Preferably, one end of the plug body is fixedly connected with a wire.

[0009] Preferably, a connecting rod is fixedly installed on the outer wall of the plug body. One end of the connecting rod is fixedly installed with a fixing ring. The fixing ring is movably sleeved outside the wire, and a ring pad is fixedly installed on the inner wall of the fixing ring. The ring pad is in close contact with the outer wall surface of the wire.

[0010] Preferably, the ring pad and the groove pad are both made of wear-resistant rubber. By setting the groove pad, the connection tightness between the pin plate and the shrinkage groove can be increased, thereby improving the stability of the pin plate in the shrinkage groove.

[0011] The utility model provides a waterproof plug for a power distribution control device. The waterproof plug for the power distribution control device has the following beneficial effects:

[0012] (1) For the waterproof plug for the power distribution control device, through the waterproof cover and the waterproof groove in the waterproof fixing mechanism, good waterproof effects can be achieved on the plug body and the socket. The waterproof cover can play a certain guiding role for water droplets, avoiding water droplets flowing to the connection between the plug body and the socket through the waterproof groove. And through the pin plate, the waterproof cover can be limited, thereby improving the firmness of the connection between the plug body and the socket;

[0013] (2) For the waterproof plug for the power distribution control device, by setting the fixing ring and the connecting rod, a certain supporting effect can be achieved on the wire close to one end of the plug body, avoiding the wire close to one end of the plug body from breaking during long-term use. And through the groove pad, hard contact between the wire and the fixing ring can be avoided, reducing wear and improving the service life of the wire, with strong practicability.

One end of the connecting rod 7 is fixedly installed with a fixing ring 5. The fixing ring 5 is movably sleeved outside the wire 3. And a ring pad 6 is fixedly installed on the inner wall of the fixing ring 5. The ring pad 6 is in close contact with the outer wall surface of the wire 3.

[0035] Specifically, in the above technical solution, by providing the fixing ring 5 and the connecting rod 7, a certain supporting effect can be exerted on the wire 3 near one end of the plug body 2, preventing the wire 3 near one end of the plug body 2 from breaking during long-term use. Moreover, through the groove pad 408, hard contact between the wire 3 and the fixing ring 5 can be avoided, wear can be reduced, the service life of the wire 3 can be prolonged, and the practicability is strong.

[0036] Furthermore, the materials of the ring pad 6 and the groove pad 408 are both wear-resistant rubber;

[0037] Among them, by providing the groove pad 408, the connection tightness between the pin plate 404 and the shrinkage groove 403 can be increased, thereby improving the stability of the pin plate 404 in the shrinkage groove 403.
