Abstract
The utility model discloses a plug, comprising a plug body and contact pins. The contact pins and a power line are electrically connected through a temperature control device. The temperature control device disconnects when temperature of the plug is higher than safe temperature. The plug can protect electrical equipment, and personal and property safety, and power utilization is made safe and reliable.
Description
Technical field
The utility model relates to a kind of plug.
Background technology
At present; plug does not have the function of overtemperature protection, and is insecure if the plug end contact pin is connected with the power line copper wire, is to produce high temperature using high-power electric appliance; if untimely cutting off the electricity supply causes easily security incident even cause fire, there is very large potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model just provides a kind of plug that can carry out overtemperature protection simple in structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme, and a kind of plug comprises plug body and the contact pin of being located on the plug body, be electrically connected by attemperating unit between described contact pin and the power line, described attemperating unit is higher than in the safe temperature situation in the plug temperature and disconnects.
Attemperating unit can disconnect when the plug temperature is higher than safe temperature, i.e. connection between contact pin and the power line disconnects, and plays the effect of overtemperature protection.
As a kind of preferred scheme, described contact pin top arranges jack, and described attemperating unit is the manual thermostat that comprises reset button, and described plug body is provided with through hole, and described reset button is passed described through hole.
As the preferred scheme of another kind, described attemperating unit is can automatically reset automatic thermostat.
Preferably, described plug body is provided with socket, and described socket is provided with jack, and described jack is electrically connected with described contact pin by described attemperating unit.
Described attemperating unit can carry out overtemperature protection synchronously to the plug that is inserted in the described jack.
Preferably, to be that two hole circles are inserted or two holes are flat insert or insert in five holes described jack.
Preferably, described plug body bottom margin is offered louvre.
The plug that the utility model provides can disconnect when the plug temperature is higher than safe temperature by in inside attemperating unit being set, and can protect electric equipment, and the person and property safety make electricity consumption more safe and reliable.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model plug interior structure schematic diagram;
Fig. 2 is the external structure schematic diagram of the utility model plug;
Fig. 3 is the three-dimensional exploded view of the utility model plug.
Embodiment
As shown in Figure 1 to Figure 3, be a kind of plug of the utility model, comprise plug body and be located at contact pin 2 on the plug body, be electrically connected by attemperating unit 1 between described contact pin 2 and the power line 3 that described attemperating unit 1 is higher than in the safe temperature situation in the plug temperature and disconnects.
The end that described power line 3 stretches into described plug body is located between wire bushing 31 and the tension disc 32, and described tension disc 32 two ends are provided with through hole, and screw 33 passes described through hole and is screwed onto on the interior joint pin of described plug body, fixing described power line 3.
The contact pin 2 of described plug and power line 3 are electrically connected by described attemperating unit 1, and described attemperating unit 1 disconnects in the safe temperature situation when the plug temperature is higher than, and is corresponding, and the contact pin 2 that links to each other by attemperating unit 1 disconnects with power line 3, reaches the purpose of overtemperature protection.
In the present embodiment, described attemperating unit 1 selects figure to jump the formula thermostat, and particularly, described attemperating unit 1 is the manual thermostat that comprises reset button 11, and described plug body is provided with through hole 5, and described reset button 11 is passed described through hole 5.Thermostat is pressed reset button 11 after disconnecting, and thermostat is connected.
Be understandable that described attemperating unit 1 can also be selected can automatically reset automatic thermostat.After thermostat disconnects, and described plug drop in temperature, the connection that automatically resets of described thermostat.
Described plug body is provided with socket 4, and described socket 4 is provided with jack 41, and described jack 41 is electrically connected with described contact pin 2 by described attemperating unit 1.Particularly, the conducting strip 42 of described jack 41 links to each other with the connecting portion of described contact pin 2 and described attemperating unit 1.Thus, described attemperating unit can be protected the electrical equipment that is connected to described jack 41.Be understandable that the conducting strip 42 of described jack 41 can only connect described contact pin 2 and not connect described attemperating unit 1, that is, described plug is used as adapter.
Described socket 4 is positioned on the described plug body by buckle structure 43, and described buckle framework 43 is grab and draw-in groove, and one of them is arranged on described grab and draw-in groove on the described plug body, and another is arranged on the described socket 4.Further, by hold-down screw 45 that described plug body and socket 44 is fixing.
To be that two hole circles are inserted or two holes are flat insert or insert in five holes described jack 41, adapts to different electrical appliance user demands.
Described plug body bottom margin is offered louvre 6.
In the present embodiment, described plug body bottom margin is offered two arc louvres 6.
