Description
Technical field
The utility model relates to a kind of micro coaxial cable connector assembly, particularly relates to a kind of attaching plug with high temperature automatic protection functions.
Background technology
Attaching plug is the critical component that electric equipment is connected with power supply, and having many uses of it is general, and big and small industry all may need attaching plug, can say and where need electricity, where just has attaching plug.Attaching plug roughly can be divided into conversion electric power plug, injection moulding attaching plug and assembling attaching plug.Conversion electric power plug is exactly the attaching plug plug of a national standard being converted to another national standard; Injection plug be exactly plug and line by high temperature, high pressure forces together, once shaping, just cannot install and remove, such attaching plug feature clearly, firmly, safety.On market, the general attaching plug more than 80% circulated is all this attaching plug; Assembling plug is exactly that power line and plug are fixed together by screw etc., but in use can install and remove, and this ensure that the flexibility of attaching plug.Attaching plug connects domestic power supply usually, and household voltage is 220 volts, and the heat of generation is high, and high heat toasts the plastic shell of attaching plug outside for a long time, damages shell, likely causes electric leakage, also shortens the useful life of attaching plug.
So, be necessary to improve above-mentioned technical problem.
Utility model content
The purpose of this utility model there are provided a kind ofly has the attaching plug improving useful life.
For realizing aforementioned object, the utility model adopts following technical scheme: a kind of attaching plug, in order to transmit three-phase alternating-current supply, it comprises insulating body, be located at some conducting terminals on insulating body and a cable, described attaching plug also comprises a thermistor, described cable comprises a zero line, a live wire, a ground wire and a pair holding wire, and described zero line, live wire and ground wire link together one by one with conducting terminal respectively, and this links together to holding wire and thermistor.
As further improvement of the utility model, described conducting terminal is three and arrangement triangular in shape, and each conducting terminal comprises the contact site protruding out forward insulating body and the weld part extending back insulating body, and described thermistor is near weld part.
As further improvement of the utility model, described thermistor and insulating body and conducting terminal spaced apart.
As further improvement of the utility model, described attaching plug also comprises and is overmolded onto insulating body, the weld part of conducting terminal and the insulation crust of thermistor outside.
The utility model attaching plug also comprises a thermistor, described cable comprises a zero line, one live wire, one ground wire and a pair holding wire, described zero line, live wire and ground wire link together one by one with conducting terminal respectively, this links together to holding wire and thermistor, attaching plug is in transmission power supply process, the heat that conducting terminal and cable produce, the variations in temperature of attaching plug can be caused, thermistor can sense variations in temperature, if temperature is too high, then can short circuit or open circuit, thus control system to hint interrupts power delivery, prevent from damaging attaching plug, extend the useful life of attaching plug.
Accompanying drawing explanation
Fig. 1 is the three-dimensional combination figure of the utility model attaching plug.
Fig. 2 is the inner side schematic diagram of the utility model attaching plug.
Embodiment
Refer to shown in Fig. 1 to Fig. 2, the utility model attaching plug 100 is in order to transmit three-phase alternating-current supply, and it comprises insulating body 10, some conducting terminals 20, thermistor 30, insulation crust 40 and a cable 50.
Conducting terminal 20 is three and arrangement triangular in shape, and conducting terminal 20 is fixed on insulating body 10, and each conducting terminal 20 comprises the contact site 21 protruding out forward insulating body 10 and the weld part 22 extending back insulating body 10.
Thermistor 30 near the weld part 22 of conducting terminal 20, with insulating body 10 and conducting terminal 20 spaced apart.
Cable 50 comprises zero line 51, live wire 52, ground wire 53 and a pair holding wire 54, and zero line 51, live wire 52 and ground wire 53 weld together with the weld part 22 of corresponding conducting terminal 20 respectively.This links together to holding wire 54 and thermistor 30.
It is outside that insulation crust 40 is overmolded onto insulating body 10, the weld part 22 of conducting terminal 20 and thermistor 30, and conducting terminal 20 and thermistor 30 are reliably combined with cable 50.
The utility model attaching plug 100 is in transmission power supply process, the heat that conducting terminal 20 and cable 50 produce, the variations in temperature of attaching plug 100 can be caused, thermistor 30 can sense variations in temperature, if temperature is too high, then can short circuit or open circuit, thus control system to hint interrupts power delivery, prevent from damaging attaching plug 100, extend the useful life of attaching plug 100.
Although be example object, disclose preferred implementation of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
