Conductive wire cores (3) in the cable body (B) are extended into the overheating protection module (A). The overheating protection module (A) comprises an injection body (1) and overheating protection units. The number of the overheating protection units is the same as the number of the conductive wire cores. Each overheating protection unit comprises an insulating wire core (2), a conductive wire core (3), an overtemperature control protector (4) and wire connection terminals (5). The overtemperature control protector (4) is serially connected with the conductive wire core (3) through the wire connection terminals (5) arranged on two ends of the overtemperature control protector (4). The radial outer portion of each conductive wire core (3) is coated with the insulating wire core (2). According to the utility model, the circuit aging and short-circuit problems caused by overheating in the wire cable and caused potential risk problems can be solved, and security assurance is provided for production and life.
Description
Technical field
The utility model relates to a kind of intelligentized electric wire, this cable can be in the time that serviceability temperature exceedes permissible value automatic shutoff circuit, belong to the innovative technology in electric wire.
Background technology
While occurring in cable line that short circuit or overload etc. are abnormal; various defencive functions in electric power system are more complete; but the connector junction especially in cable junction; overheatedly in system, not yet there is a perfect protection due to what loose contact caused; and overheated be also to cause that cable line is aging, the main cause of short circuit, when serious, may burn even initiation fire of circuit.
For this reason, ubiquity is for the demand that can solve due to the electric wire of the problems such as the cable junction overheated cable line causing that especially loose contact of connector junction causes is aging, short circuit.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, electric wire with overheat protective function that can cut off voluntarily circuit in the time that cable is overheated.
For achieving the above object, the utility model provides a kind of electric wire with overheat protective function, this cable is made up of overtemperature protection module (A) and cable body (B), and the conductor wire core (3) in cable body (B) stretches into overtemperature protection module (A); Overtemperature protection module (A) comprises injection molding body (1) and overtemperature protection unit, and the number of overtemperature protection unit is identical with the number of conductor wire core; Overtemperature protection unit comprises insulated wire cores (2), a described conductor wire core (3), overtemperture control protector (4) and binding post (5), and overtemperture control protector (4) is in series and is connected with conductor wire core (3) by the binding post (5) that is arranged on its two ends; Insulated wire cores (2) is wrapped in the radially outer of described conductor wire core (3).
Described overtemperature protection unit is provided with more than two, overtemperture control protector (4) in the radial direction with a described cable body (B) in conductor wire core (3) close contact, and axial distance >=5mm between adjacent overtemperture control protector (4).
Injection molding body (1) is injection molding type or modular protection housing.
Overtemperature protection module (A) is no more than 300mm with the distance that uses terminal or shunting point.
The volume of overtemperature protection module (A) is less than or equal to 500cm
3.
The utility model is simple in structure, is convenient to manufacture and use.The utlity model has overheated defencive function of autotomying; in the time that cable causes cable temperature to exceed design temperature due to the unusual condition such as loose contact, overcurrent; overtemperture control protector can open circuit; protection circuit uses safety, avoids excess Temperature to cause the reasons such as cable line is aging, short circuit to cause circuit to damage and fire incident.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the C-C of Fig. 1 is to view.
Embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of electric wire with overheat protective function, and this cable is made up of overtemperature protection modules A and cable body B, and the conductor wire core 3 in cable body B stretches into overtemperature protection modules A.Overtemperature protection modules A comprises injection molding body 1 and overtemperature protection unit, and the number of overtemperature protection unit is identical with the number of conductor wire core.
Overtemperature protection unit comprises insulated wire cores 2, described conductor wire core 3, overtemperture control protector 4 and a binding post 5, and overtemperture control protector 4 is in series and is connected with conductor wire core 3 by the binding post 5 that is arranged on its two ends; Insulated wire cores 2 is wrapped in the radially outer of described conductor wire core 3.Each parts are conventional prior art, and therefore each parts concrete structure separately no longer describes in detail.
Described overtemperature protection unit is provided with more than two, is preferably provided with as shown in the figure 3.Overtemperture control protector 4 in the radial direction with a described cable body B in conductor wire core 3 close contacts, with the temperature of accurate perception conductor wire core 3, and axial distance >=5mm between adjacent overtemperture control protector 4, in order to avoid mutually interfere and affect.
Injection molding body 1 is injection molding type or modular protection housing.It is insulated wire cores 2, conductor wire core 3, and overtemperature protection modules A is made in overtemperture control protector 4 and binding post 5 sealings.
Wherein, overtemperature protection modules A is no more than 300mm with the distance that uses terminal or shunting point.For easy to use, the volume of overtemperature protection modules A is less than or equal to 500cm
3.The design temperature of overtemperture control protector 4 is more than or equal to 40 DEG C and be less than or equal to 120 DEG C.In work, when the temperature of cable exceedes design temperature, overtemperture control protector 4 is got involved protection, open circuit.
In use, overtemperature protection modules A is connected in and uses terminal or shunting point, and overtemperature protection modules A is no more than 300mm with the distance that uses terminal or shunting point.When electric wire is due to the external factor such as loose contact, overcurrent
causewhen cable temperature exceedes the design temperature of 40 DEG C-120 DEG C; overtemperture control protector 4 in overtemperature protection module can disconnect connected conductor wire core because of excess Temperature; thereby realize the disconnection of circuit; and then cable temperature is reduced, the generation of the accidents such as the cable of having avoided causing because cable temperature is too high burns out, fire.
This electric wire with overheat protective function has solved in electric wire circuit due to the overheated aging circuit causing, short circuit and the security hidden trouble that caused by it, for producing, life provides safety guarantee.
