The hot double-metal sheets and the metal sheet are fixed in the socket body. The utility model has the characteristics of convenience, practicability, safety, reliability, good protection performance, easy fabrication, low cost, etc. The utility model can control hazardous factors in the power supply system at the generation link, and does not influence the use of other electrical appliances. Therefore, the utility model is a novel socket which is safe, economic and practical.
Description
Overcurrent protection socket described in the utility model is a kind of novel power supply socket that overcurrent protective device is housed in common socket.
At present, be to utilize fuse power consumption being limited the universal way of being taked as protective device.But fuse needs often to change, just in case replacing is improper, does not just have safety effect.Especially people often occur making fuse with other wire in order to save trouble, and this has just caused great potential hazard.In addition, control in a plurality of users' the electric power system at safeties of use, locate as most of dormitories, hotel, office building, old-fashioned dwelling house etc., it is excessive individual user's electricity consumption often to occur, but total electricity consumption is no more than the use power of fuse and does not fuse, thereby the hidden danger of causing the accident, just in case have an accident, its consequence is hardly imaginable.At existing problem in the prior art, the novel overcurrent protection socket of a kind of practical simplicity of research and design is very necessary thereby overcome the problems referred to above.
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of convenient and practical, safe and reliable, manufacturing is simple, with low cost, protectiveness is good novel overcurrent protection socket of Development and design.The utility model is to make according to the principle of thrermostatic bimetal-plate overcurrent expanded by heating.Moving contact and sheet metal are processed as one, directly constitute current path, and be installed in the common socket, thereby make a kind of economical and practical novel overcurrent protection socket.
Overcurrent protection socket described in the utility model, its structure is made up of socket, overcurrent protector, sheet metal.Overcurrent protector is made of thrermostatic bimetal-plate and moving contact.The elastic metallic folder is equipped with in the upper end of a thrermostatic bimetal-plate, and corresponding with jack, and its lower end is fixed with a moving contact, and contacts with the moving contact that is packed in another thrermostatic bimetal-plate upper end; Thrermostatic bimetal-plate and sheet metal all are installed in the socket.Thrermostatic bimetal-plate in the overcurrent protector described in the utility model is made up of active layers and passive layer two parts, and active layers can be manufactured by copper 62 zinc 38 materials, and passive layer can be manufactured by the invar alloy material.
Overcurrent protection socket provided by the utility model is a kind of novel electrical appliance, and it mainly has following characteristics:
1, the utility model has increased an overcurrent protector than common power socket, but automatic power on-off, and it is reliable to be active in one's movements.Adopt the utility model the hazards in the electric power system can be controlled at the generation link, and do not involve other user, so have characteristics such as convenient and practical, safe and reliable.
2, the utility model is made of common socket and thrermostatic bimetal-plate overcurrent protector, has characteristics such as simple in structure, cheap, good manufacturability, volume be little.
3, because the utility model is specially adapted to centralized control, the economize on electricity safety of the distributed electric power system of user is transformed.So can be widely used in places such as dormitory, hospital, hotel, school, office building, old-fashioned dwelling house, its applicable surface is very extensive, has vast market prospect.
In sum as can be known, of the present utility model being extensive use of will produce positive social benefit and remarkable economic efficiency.
The utility model has two accompanying drawings, and wherein: accompanying drawing 1 is the structural representation of overcurrent protection socket.Accompanying drawing 2 is overcurrent protection socket fundamental diagrams.
Among the figure: 1, socket 2, jack 3, jack 4, thrermostatic bimetal-plate
5, thrermostatic bimetal-plate 6, sheet metal 7, moving contact 8, moving contact
9, plug metal film 10, plug 11, plug metal film
12, elastic metallic folder 13, elastic metallic folder
Specific embodiment of the utility model as shown in drawings, its structure is by socket (1), thrermostatic bimetal-plate (4,5), moving contact (7,8) and sheet metal (6) are formed.Thrermostatic bimetal-plate (4,5) and sheet metal (6) all are packed on the socket (1), and elastic metallic folder (12) same jack (3) of thrermostatic bimetal-plate (4) upper end is corresponding, and elastic metallic folder (13) same jack (2) of sheet metal (6) upper end is corresponding.The lower end of thrermostatic bimetal-plate (4) is fixed with moving contact (8) by riveted way.The upper end of thrermostatic bimetal-plate (5) is fixed with moving contact (7) by riveted way, and thrermostatic bimetal-plate (5) is connected with external power supply respectively with the lower end of sheet metal (6).Moving contact of manufacturing by copper product (7) and moving contact (8) the formation current path that contacts.Two plug metal films (9,11) of the plug of external electrical appliance (10) are connected with power supply by inserting jack (3,2).Operation principle of the present utility model is the operating current when the overcurrent protection electrical appliance that socket patched when exceeding the current value that overcurrent protector sets, and this protector can automatic disconnection and cut off the electricity supply.Critical component of the present utility model is an overcurrent protector, and it is to make according to the principle of thrermostatic bimetal-plate overcurrent expanded by heating.The active layers of thrermostatic bimetal-plate is manufactured by the Cu62Zn38 material, and passive layer is manufactured by the invar alloy material.Moving contact is with the thrermostatic bimetal-plate formation current path that is fixed together.When excessive by electric current, thrermostatic bimetal-plate generates heat after to a certain degree, and flexural deformation and make moving contact action and open circuit voluntarily after thrermostatic bimetal-plate cools off gradually, resets moving contact and resile, automatic recovery of power supply.To use of the present utility model, effectively limited subscriber is to the control of electrical appliance power consumption by the user.
