Description

Wall-mounted big electric current socket

Technical field

The present invention relates to a kind of low voltage equipment, particularly a kind of wall-mounted big electric current socket.

Background technology

Socket is as the power supply access point of domestic electric appliance; Mainly be traditional mechanical structure formula socket, the type socket adopts copper bar to connect fully, can satisfy the needs of various current specification; But it is charged always that shortcoming is a socket itself; The electrical equipment that is attached thereto can be in holding state always, both dangerously can not satisfy energy-conservation needs, more can't satisfy the needs of the intelligent control of modern house.

Along with development of electronic technology, electronic type control socket progresses into market, but for satisfying the requirement that mutual alternative is installed, the type socket has and the identical outline overall and installing dimensions of traditional mechanical structural formula socket.We can say; The design of electronic type control socket has remedied that traditional mechanical structural formula socket can't cut off the power supply automatically, the shortcoming of automatic power, but therefore receives the restriction of socket inner space; It can't be as mechanical structural formula socket; Realize copper bar cabling completely, thus can only be used for the power consumption equipment of some less current classes, thereby big limitations the range of application of the type socket.

Electronic type control socket form in the market mostly adopts following two kinds of realizations: (1) socket power is after the binding post that welds on the control circuit board inserts; Electric current covers copper layer cabling through circuit board and flows to relay on control circuit board; After relay flows out; With flexible conductor this electric current is connected with the sleeve spot welding of socket front end, thus the transmission and the transition of realization electric current.(2) similar with mode (1), difference only is that no longer adopting is flexible coupling and is welded to connect, but socket and bush directly is welded on the control circuit board through the project organization pin, realizes the transmission and the transition of electric current.Like application for a patent for invention number is a kind of remote control socket on wall that 200810161331.8 patent is described.

More than the mode of two kinds of prior aries; Which kind of no matter adopts, all can't avoid electric current to understand some flowing on control circuit board, this is for using in several amperes of rated current and following power consumption equipment; Because heating is little, can satisfy instructions for use basically.But for (power like cabinet air-conditioner 3P can reach 3KW, calculates with household voltage 220V, and electric current is about 14A than large power-consuming equipment; Starting electric current constantly can reach nearly 42A especially), because of electric current is bigger, caloric value is directly proportional with current squaring; Heating is serious, covering copper layer cabling mode and can't satisfy instructions for use basically on the control circuit board, if for a long time on control circuit board through big electric current; Can have that Copper Foil is aging to peel off, cause damage, even cause big potential safety hazard such as fire.

Summary of the invention

The objective of the invention is provides a kind of wall-mounted big electric current socket to the defective that exists in the prior art.

Housing 82 of the present invention is the front and back isolation structure, and the L utmost point, the N utmost point, three sleeves 81 of the E utmost point are assemblied in three sleeve inner chambers 823 in housing 82 fronts, and wherein the N utmost point 81a of sleeve, E utmost point 81b directly are connected with the power supply N utmost point, E utmost point inlet wire; Sleeve L utmost point 81c is connected with the outlet side copper bar pin 83b1 of relay 83b through clamp structure 81c2; The inlet wire side copper bar pin 83b2 of relay 83b is connected with the clamp structure 841 of connecting plate 84; Connecting plate 84 directly is connected with power supply L utmost point inlet wire; Form link circuit by the relay 83b on L utmost point sleeve 81c, the control circuit board 83, connecting plate 84, power supply L utmost point inlet wire; Housing 82 is provided with leaded light post installation cavity 821, release link via hole 822, and installation cavity 821 is the groove of rectangle, and release link via hole 822 is a cylindrical hole; Release link 6, leaded light post 7 are installed in the release link via hole 822, leaded light post installation cavity 821 in the front of housing 82, housing 82 rear side installation and control circuit boards 83.

Advantage of the present invention is to connect at the complete copper bar of the inner realization of socket through Optimal Structure Designing; Make main circuit current be carried on the copper bar fully; The scope of application is in full accord with traditional mechanical structure formula socket; The needs of all size electric current power consumption equipment have been satisfied, in family expenses, the big electric current power consumption equipment in office space; The control of integrated electronic formula, and only carry control circuit electric current (milliampere level) on the control circuit board, realized the characteristics of intelligent control.And socket provided by the present invention, on its overall dimension and the mounting means fully can with the above traditional mechanical structural formula socket of mentioning, conditional electronic control type socket mutual alternative.Through architecture advances,, can satisfy intelligent control and the energy-conservation needs of power consumption equipment, compact conformation, reliable operation, practical with sleeve and control circuit board effective integration to conventional socket.
