Abstract
The invention discloses a power converter. A sliding slot (16) is arranged between a middle shell body (1) and a lower shell body (4). A plug bush support (6) is mounted in the slide slot through a sliding block (15). An integral-type plug bush (7) is mounted in the plug bush support. A pressure-regulating sliding slot (12) is arranged in the plug bush support. A pressure-regulating elastic sheet (11) and pressure-regulating sliding blocks (10) are mounted in the pressure-regulating sliding slot, wherein the pressure-regulating sliding blocks are connected through pressure regulating screws (9). Compared with the prior art, the power converter achieves the effect that a plug sheet and a plug bush of a plug are in surface contact, can increase the current carrying capacity of a current carrying body substantially, avoids the accidents such as a fire and an electric shock caused by heating, ignition and other phenomena which happen due to the fact that the plug is in poor contact with a socket, and reduces the occurrences of potential safety hazards; meanwhile, the effect that the plug bush can be repaired through the adjustment of the pressure of the elastic sheet when the plug bush is seriously worn or the elasticity of the plug bush is lowered after the plug bush is used for a long term, therefore, the service life of the power converter is prolonged, the use cost is lowered, and resources are saved.

Current, various power supply changeover device (i.e. supply socket) is that people live indispensable little electrical materials and appliances, although object is very little and be worth not high, direct relation the person of people and the safety problem of property.According to the statistics made by the departments concerned, in China's nearly 10 years accumulative fire incidents occurred, the electric shock caused due to the reason such as supply socket, switch short and fire occupy first of all kinds of fire incident reason, and in urban and rural residents' home fire, nearly 80% is relevant with supply socket fault or line broken circuit.Visible, the security protection quality of power supply changeover device is directly connected to the home safety of people.
Various power supply changeover device in use, be short-circuited, sparking, the reason of heating and electric shock accidents has material poor, use inferior materials and turn out substandard goods, the using method etc. of Structure Designing Problem and mistake, key issue is live wire, zero line, the not science of the gap between the terminal of ground wire and wiring and creepage distance design, unreasonable the causing of sleeve design, the power supply changeover device produced by national standard commercially available at present, even if material and size conforms quality requirement, but due to the congenital flaw of sleeve design, when the latch of plug inserts in power supply sleeve, major part contacts or the form of partial line contact for partial points, heating or spark phenomenon will inevitably be there is when insufficient load current, especially at power supply changeover device through Long-Time Service, sleeve metal covering is oxidized, wearing and tearing, bad consequence is more easily come in contact after distortion, thus various power supply changeover device in the prior art also exists serious potential safety hazard.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of power supply changeover device, the effect that the inserted sheet realizing plug contacts with sleeve face, effectively can make the inserted sheet close contact of sleeve and plug, increase substantially the contact-making surface of current carrying object, avoid all kinds of accidents produced because of the loose contact of power supply changeover device, reduce the generation of potential safety hazard, the adjustable reparation of sleeve can be realized simultaneously, thus extend the useful life of power supply changeover device, reduce use cost, save resource.
To achieve these goals, this power supply changeover device comprises middle shell, and coordinates with it upper shell and the lower house of installation, and middle shell has been threaded connection base plate, binding post is by middle shell and base plate enclosed package in lower house, and binding post is reliably connected with intermediate terminal;
Chute is provided with between middle shell and lower house, coordinated by slide block in chute and sleeve support is installed, integral type sleeve is installed in sleeve support, the inner side of sleeve support is provided with pressure regulation chute, pressure regulation shell fragment is installed in pressure regulation chute, and by the pressure regulation slide block that voltage regulation screw connects, pressure regulation slide block pushes down pressure regulation shell fragment by voltage regulation screw.
Binding post is built-in clamping plate type binding post, and whole electrified body is all hidden and is arranged in the shell of binding post.
Compared with prior art, this power supply change-over device passes through Slidable sleeve support and the integral type sleeve of setting, and utilize the mode of slide block and chute cooperating, the effect that the inserted sheet achieving plug contacts with sleeve face, significantly can improve the ampacity of carrying object, avoid the loose contact because of plug and socket and the phenomenon such as heating, sparking that produces and the fire, the electric shock accidents that cause, reduce the generation of potential safety hazard; Pressure regulation chute, pressure regulation shell fragment simultaneously by arranging in sleeve support, and the mode of pressure regulation slide block is connected by voltage regulation screw, when achieving serious wear or elasticity reduction when Long-Time Service sleeve, can be repaired by regulating shell fragment pressure, thus extend the useful life of power supply changeover device, reduce use cost, save resource.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figures 1 to 4, this power supply changeover device comprises middle shell 1, and coordinate with it upper shell 2 and the lower house 4 of installation, middle shell 1 has been threaded connection base plate 5, binding post 14 is by middle shell 1 and base plate 5 enclosed package in lower house 4, and binding post 14 is reliably connected with intermediate terminal 13; As shown in Figure 1, the position that upper shell 2 is corresponding with sleeve is provided with jack 3.
Chute 16 is provided with between middle shell 1 and lower house 4, coordinated by slide block 15 in chute 16 and sleeve support 6 is installed, sleeve support 6 passes through the effect of slide block 15 and chute 16, can do appropriate slippage with attaching plug tab central apart from the change of error along the vertical line direction of sleeve contact-making surface; Be provided with integral type sleeve 7 in sleeve support 6, the facade of sleeve support 6, as protective surface, can prevent the distortion of integral type sleeve 7 and between sleeve, play insulation blocking effect; The inner side of sleeve support 6 is provided with pressure regulation chute 12, is provided with pressure regulation shell fragment 11 in pressure regulation chute 12, and by the pressure regulation slide block 10 that voltage regulation screw 9 connects, pressure regulation slide block 10 pushes down pressure regulation shell fragment 11 by voltage regulation screw 9.
