Abstract
The utility model relates to a protecting connecting line against the over current, comprising two conductors; terminals of external wirings are connected with the ends of the conductors; at least a conductor is in series connected with the over current protector; a rib is sheathed on the terminals with external wirings; the over current protector is enwrapped in the rib. With the utility model, the over current protector is in series connected with the common conductors, the protection is realized by the resistance or the fuse, thereby the conductors are protected, the safety to use the conductors is improved. The utility model has the advantages of simple structure, low cost, and better safety performance, which is suitable for popularization and application.
Description
Technical field:
The utility model relates to the connecting line technical field, the anti-overcurrent protection connecting line that particularly a kind of fail safe is higher.
Background technology:
Cable is being brought into play great function in national economy, all need to use a large amount of cables in industry, the life, and the security incident that is caused because of the quality of cable own also happens occasionally, so the fail safe of various electric wires also more and more is subjected to people's attention.Electric wire must bear long energising, but also must have certain pull resistance.General connecting line, as the connecting line of products such as fan, refrigerator, itself has certain thickness insulating barrier and line footpath bigger, can bear by certain electric current and by relevant safety test, and the use of electrical appliance is not influenced fail safe; And the output connecting line of household electronic products such as picture mobile phone or other battery charger, because cost problem and little current work, the insulating barrier of cable is thin and the line footpath is less, under the situation that long-time energising is used, it is aging to be easy to distortion, and if connect short circuit between the charging end line of battery, can produce very big feedback electric current, this connecting line is easy to hot even on fire, thereby causes immeasurable loss.
The utility model content:
The purpose of this utility model is to provide a kind of fail safe higher anti-overcurrent protection connecting line at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme: it includes two leads, and wire end is connected with the external cabling terminal, and at least one lead is in series with overcurrent protector.
Described overcurrent protector is a resistance.
Described overcurrent protector is a fuse.
Described external cabling terminal is enclosed with rib, and overcurrent protector is wrapped in the rib.
The utility model is in series with overcurrent protector on plain conductor, can adopt resistance or fuse to realize, thus guardwire; improve the fail safe that lead uses; the utlity model has advantages such as simple in structure, that cost is low, and security performance is preferable, be fit to apply.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a use schematic diagram one of the present utility model;
Fig. 2 is a use schematic diagram two of the present utility model.
Embodiment:
See accompanying drawing 1,2, the utility model includes two leads 10, connects the positive and negative electrode of power supply respectively, the lead 10 terminal external cabling terminals 30 that connect, and wherein a lead is in series with overcurrent protector 20.
Described overcurrent protector 20 can adopt resistance, and the resistance value ratio of this resistance is less.According to Ohm's law V=IR, I is the current value that flows through, and R is the protective resistance value, and V is the voltage drop that produces; Voltage drop is very little when normal the use, do not influence use.But when product under improper situation, when being short-circuited between the lead 10, can producing a very big feedback electric current and flow through lead 10 and protector 20, according to electrical principles P=I
2R, I are the current values that flows through, and R is the protective resistance value, and P is the power that consumes on protective resistance; When protective resistance flows through very big electric current, consume the nominal operation power that is far longer than it at ohmically power, but moment fusing resistor, and then guardwire 10.
Described overcurrent protector 20 can also adopt fuse; When the electric current of the lead 10 of flowing through was excessive, fuse fused automatically, with guardwire 10.
Described external cabling terminal 30 is enclosed with rib 40, and overcurrent protector 20 is wrapped in the rib 40.The main effect of rib 40 is the pull resistances that improve the lead 10 of series connection overcurrent protector 20 positions, plays the effect of indirect protection overcurrent protector 20.In addition, overcurrent protector 20 is connected on the end of lead 10, can protects whole lead 10 rather than local lead.External cabling terminal 30 and overcurrent protector 20 are injection-moulded in together, have both improved pull resistance and also made product miniaturization and more attractive in appearance.
The utlity model has advantages such as simple in structure, that cost is low, and security performance is preferable, be fit to apply.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
