Description

Technical Field

[0001] The utility model belongs to the field of industrial plugs, and particularly relates to an industrial plug with high safety. Background Art

[0002] Industrial plugs are widely used in the industrial field. The safety of industrial plugs directly determines the efficiency of industrial production. Currently, there are many kinds of industrial plugs, with functions such as dustproof and waterproof. However, in actual use, the safety of plugs is the primary factor to be considered in industry. Most of the internal wiring terminals of current industrial plugs are directly connected to the power wires and pre-assembled. When in use, just plug the wiring terminals into the socket.

[0003] According to a Chinese patent with the announcement number "CN218783263U", a highly safe industrial plug is disclosed, including an industrial plug and a matching socket, the industrial plug including a plug shell, the socket including a socket shell, one side surface of the socket shell is provided with two socket grooves, the plug shell is provided with a plug cavity, one side inner wall of the plug cavity is provided with two plugs, the two plugs match the socket grooves, the plug cavity is provided with a protection block, the surface of the protection block is provided with two protection holes, the outer surface of the plug shell is provided with a first fixing ring, and the outer surface of the socket shell is provided with a second fixing ring. The protection block structure provided by the utility model has protection holes on the surface of the protection block to avoid contact between hands and the plug and reduce the risk of electric shock; the inner wall of the first fixing ring is provided with threads, and the outer wall of the second fixing ring is provided with threads to ensure that the plug and the socket are tightly connected to prevent poor contact;

[0004] It can be seen from the above structure that the inner wall of the first fixing ring is provided with a thread, and the outer wall of the second fixing ring is provided with a thread, and the threads of the two match each other, thereby ensuring that the industrial plug is tightly connected to the industrial socket, preventing poor contact, and ensuring safe use. However, the connection through the set thread requires twisting the first fixing ring or the second fixing ring when connecting the plug to the slot to achieve the plug-in effect, which results in a relatively slow connection and cannot achieve a quick connection or disassembly effect. At the same time, the joint structure cannot achieve an effective waterproof effect. Utility Model Content

[0015] First, by setting the anti-dropping component, when the plug shell and the socket shell are plugged into each other during use, the card connector on the surface of the socket shell is first pressed downward to make the card connector enter the inside of the circular groove, and then the slot body and the plug body can be plugged in. After the plug body and the slot body are plugged into the appropriate positions, the positions of the circular groove and the card hole are consistent, and then the card connector is popped out of the circular groove under the action of the card spring, so that the card connector and the card hole are carded with each other. After the card connection is completed, the plug shell and the socket shell can be limited, thereby avoiding the short circuit caused by the loose connection between the plug body and the slot body;

[0016] Second, after the plug shell and the socket shell are plugged into the outside, the second protective shell and the first protective shell are aligned so that the plug shell and the outside of the socket can be wrapped, and then the external thread groove and the internal thread cylinder are threadedly connected, so that the plug body and the slot body can be protected under the action of the first protective shell and the second protective shell, and the plug shell and the socket shell can be prevented from being damaged due to pressure. The first protective shell and the second protective shell can also provide waterproof effect for the plug body and the slot body, which can prevent water from entering the inside of the plug body and the slot body, and under the action of the rubber ring, water can be prevented from entering the inside of the first protective shell and the second protective shell through the connecting wire. The rubber ring fits tightly with the connecting wire to prevent water from flowing. BRIEF DESCRIPTION OF THE DRAWINGS
