Abstract
The utility model relates to a temperature control protection element for a power supply socket and a plug. The utility model is characterized in that the inner parts of the power supply socket and the plug are respectively provided with a temperature control protection element, and the outer side of a metal sheet (4) which is arranged in each temperature control protection element is provided with a fully enclosed plastic outer coating layer (3). A plastic layer which is arranged on each plastic outer coating layer (3) and is corresponding to a platinum contact point of one side of a bimetal platinum contact (6) is provided with an open window. In the utility model, no matter what working conditions the temperature control protection elements lie in, the metal sheets can not be affected by outsides, and can not directly generate direct short accidents with metal housings.
Description
The utility model relates to the supply socket that electrical equipment uses, the temperature control protection component of plug.
At present, after the supply socket that electrical equipment is used, plug used certain the time, reed etc. can distortion, directly influenced current lead-through, and in using, extrinsic current increases suddenly sometimes, and these all can cause the temperature of plug, socket to raise, and have influenced the fail safe of electricity consumption.
The purpose of this utility model provides a kind of supply socket, plug temperature control protection component; no matter which kind of operating state plug, socket are in, as long as its temperature is elevated to certain value, circuit will disconnect; and factor one solution that causes temperature to raise, circuit recovers conducting automatically.
Technical solution of the present utility model is; one temperature control protection component is arranged on existing electrical socket, plug; one totally enclosed plastics surrounding layer is arranged outside the sheet metal of the utility model in the temperature control protection component, and the plastic layer at place, the sheet metal platinum contact of corresponding bimetal leaf platinum contact one side has unlimited window on the plastics surrounding layer.
The above temperature control protection component has a metal shell; bimetal leaf ratio-frequency welding contact is arranged on the metal shell inwall; be fixed with bimetal leaf on the pad; the other end of bimetal leaf is fixed with bimetal leaf platinum contact; corresponding fixed-site at bimetal leaf has sheet metal in the metal shell, and there is sheet metal platinum contact at place, corresponding bimetal leaf platinum contact on sheet metal.
Operation principle of the present utility model is the work that does not influence other circuit when normal operating conditions; electric current in circuit increases or supply socket; plug loose contact and cause the metal shell leading-out wire; metal shell; bimetal leaf ratio-frequency welding contact; bimetal leaf; bimetal leaf platinum solder joint; sheet metal platinum solder joint; the temperature elevation process of sheet metal; or the temperature that can cause this element equally raises because temperature on every side raises; when if temperature is elevated to the temperature T of a certain setting; bimetal leaf will be owing to the relation of different coefficient of thermal expansion and contraction; bimetal leaf has been lifted up and has been separated with sheet metal, and circuit disconnects and plays a protective role.And got rid of cause overheated reason after, bimetal leaf reduces the state of resuming work because of its temperature, bimetal leaf platinum contact and sheet metal platinum contact join, circuit turn-on.Sheet metal of the present utility model is because of fully closed one deck plastics surrounding layer that is surrounded by, therefore in user mode, because of have on the sheet metal plastics surrounding layer not can with the metal shell accident that is short-circuited.In addition, the corresponding plastic layer of locating in the metal platinum contact of bimetal leaf platinum contact one side has unlimited window on the plastics surrounding layer, therefore can not influence the operate as normal of bimetal leaf and sheet metal.
The plastics of sheet metal plastics surrounding layer of the present utility model are the flame-resistant high-temperature-resistant plastics preferably.
The utility model has the advantages that no matter which kind of operating state the temperature control protection component is in, and sheet metal all can not be subjected to ectocine, can be because of do not contact the short circuit accident that takes place with metal shell yet.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 is a temperature control protection component aufbauprinciple schematic diagram of the present utility model;
Fig. 2 is the utility model temperature control protection component profile construction schematic diagram;
Fig. 3 is a temperature control protection component lead-out wire schematic diagram of the present utility model.
According to Fig. 1,2, shown in 3, the utility model has a metal shell 1, bimetal leaf ratio-frequency welding contact 5 is arranged on metal shell 1 inwall, be fixed with bimetal leaf 2 on the pad 5, the other end of bimetal leaf 2 is fixed with bimetal leaf platinum contact 6, corresponding fixed-site at bimetal leaf 2 has sheet metal 4 in the metal shell 1, outer surface at sheet metal 4 has totally enclosed plastics surrounding layer 3, the plastics of plastics surrounding layer 3 are the flame-resistant high-temperature-resistant plastics, on the position of corresponding bimetal leaf platinum contact 6 one sides on the plastics surrounding layer 3, a unlimited window is arranged, be fixed with sheet metal platinum contact 7 on the sheet metal 4 at window place.Metal shell 1 has lead-out wire 8, and sheet metal has lead-out wire 9, mutual insulating between lead-out wire 8 and the lead-out wire 9.
Claims (2)
1, a kind of supply socket, plug temperature control protection component; it is characterized in that a temperature control protection component is arranged in supply socket, plug; sheet metal (4) in the temperature control protection component has a totally enclosed plastics surrounding layer (3) outward, and the plastic layer of locating in the sheet metal platinum contact (7) of the last corresponding bimetal leaf platinum contact of plastics surrounding layer (3) (6) one sides has unlimited window.
2, a kind of supply socket according to claim 1, plug temperature control protection component; it is characterized in that the temperature control protection component has a metal shell (1); on metal shell (1) inwall, bimetal leaf ratio-frequency welding contact (5) is arranged; be fixed with bimetal leaf (2) on the pad (5); the other end of bimetal leaf (2) is fixed with bimetal leaf platinum contact (6); corresponding fixed-site at bimetal leaf (2) has sheet metal (4) in the metal shell (1), goes up the platinum contact (7) that sheet metal is located in corresponding bimetal leaf platinum contact (6) at sheet metal (4).
