Abstract

The utility model discloses an improved plug structure, which is composed of an outer casing, a pin and electrical wires, wherein a fuse is connected between the pin and a circuit. Therefore, when electric current overloads, the fuse can fuse in advance to form the off state. Therefore, the conditions that the electric wires accidentally fire, electric facilities are damaged, etc. can be prevented, therefore the substantial benefits on use of the plug are increased.

Description

Improved plug construction

Technical field

The utility model relates to a kind of improved plug construction, be connected fuse between pin and the electric wire, by setting up of this fuse, when carrying the overload electric current in plug, this fuse promptly can fuse in advance, reach situations such as the protection electric wire cocks off, thereby promote the real benefit of this plug on using.

Background technology

General plug construction is made up of shell body, one group of pin and electric wire, after it makes pin and electric wire is connected, by shell body pin and electric wire is coated and is one; Yet this general plug there is no the built-in protecting member, and therefore when overloading because of electric current, the electric equipment that another termination of electric wire is established damages, and what is more, can cock off by trigger wire, and causes fire, the loss that causes the user to expect.

So the design people is in view of above-mentioned situation, after going through thinking in many ways and constantly testing, develop a kind of plug structure safe in utilization that improves.

Summary of the invention

The purpose of this utility model provides a kind of improved plug construction, and it is made up of shell body, pin and electric wire; In being connected between pin and the circuit fuse is arranged, when electric current overloads, this fuse formation off state that promptly can in advance fuse, thus the protection electric wire cocks off, or situation such as electric equipment damage, promote the real benefit of this plug on using.

For achieving the above object, the utility model proposes a kind of improved plug construction, formed by shell body, pin and electric wire; This shell body is coated on the joining place of pin and electric wire; It is characterized in that: be provided with fuse in being connected between pin and the electric wire, the line end of this fuse one end and electric wire connects to be established, and this fuse other end connects pin.

Preferably, this fuse one termination is established pin, holds in addition in fuse to connect conductive clip again, and this conductive clip can supply to plug with general its pin of plug.

Therefore, the improved plug construction that the utility model proposes, when it overloaded in electric current, this fuse promptly can fuse in advance, formed off state, thus the protection electric wire cocks off or the situations such as damage of electric equipment.

Embodiment

At first, see also shown in Fig. 1,2, be improved plug construction of the present utility model, this plug is made up of shell body 1, one group of pin 2 and electric wire 3; Wherein:

Be connected in 3 in this pin 2 and electric wire and installed fuse 4, these fuse 4 one ends are to fix with electric wire 3 line ends, and the other end then connects with pin 2 and establishes, and by shell body 1 pin 2, electric wire 3 is coated with fuse 4 joining places again.

Therefore; by setting up of above-mentioned fuse 4, in case the electric current of overload when flowing through fuse 4 via a pin 2, will make fuse 4 produce high temperature and fuse; form off state, thereby the connected electric equipment of electric wire that protection fuse 4 another terminations are established avoids cocking off impaired.

Please consult shown in Fig. 3-5 again, be another embodiment of the present utility model, make these fuse 4 one terminations establish pin 2, the other end then connects conductive clip 3 ', and this conductive clip 3 ' can supply to plug with general its pin of plug; Thus, electric current can be flowed through earlier behind pin 2 of the present utility model, the fuse 4, again through the pin of conductive clip 3 ' galvanization to the connect general plug of establishing, the electric equipment that this plug connects is given in power supply again, so when electric current overloads, promptly block, also reach the electric current that prevents to overload and damage the electric equipment effect in fuse 4 places.

By said structure and embodiment as can be known, the utlity model has following advantage:

1. the utility model is to be connected fuse between pin and the electric wire, by setting up of fuse, can protect the overload electric current electric wire of flowing through and connect the electric equipment of establishing, and make electric equipment avoid producing disappearances such as fault, short circuit, more can prevent the cock off generation of personal property danger due to institute's initiation fire of electric wire.

2. the utility model is to establish inserted sheet in fuse one termination, again in fuse in addition end connect conductive clip, make the usefulness of switching with the electric equipment that is made for general plug, therefore, also can reach and protect the electric equipment benefits such as electric current damage that do not overloaded.

Claims

1. an improved plug construction is made up of shell body, pin and electric wire; This shell body is coated on the joining place of pin and electric wire; It is characterized in that: be provided with fuse in being connected between pin and the electric wire, the line end of this fuse one end and electric wire connects to be established, and this fuse other end connects pin.

2. improved according to claim 1 plug construction is characterized in that, this fuse one termination is established pin, holds in addition in fuse to connect conductive clip again, and this conductive clip can supply to plug with general its pin of plug.
