A kind of two safety socket of openingTechnical field:
The utility model belongs to the tool cross line safe socket in safety socket field, and what be specifically related to is a kind of two safety socket of opening.
Background technology:
Along with the development of human civilization, use the equipment of electric power also more and more, the fail safe of power receptacle more and more comes into one's own, the inside contact of existing power receptacle is all charged, when use, directly plug is inserted in socket, the sheet metal of plug is just contacted with the sheet metal in socket can connection circuit, carries out power taking.In order to improve the directly charged defect of contact in socket, someone has made improvement: a switch is set in socket, in plug is inserted into socket time, can touch switch, make conductive contact blade charged, although can avoiding child to wait, this improvement has a mind to insert and the problem of electric shock, but cannot avoid adopting metal object to be inserted in plug, particularly the object of similar plug shape inserts and makes contact charged, then make the charged defect of metal object of inserting, so, there is again following improvement: the switch arranging is as the actuating switch of another one electrode in socket, but adopt the socket of this kind of construction of switch to make loaded down with trivial details, need to connect many wires, the safety of entirety is lower, part is more, cause failure rate also higher.
Summary of the invention
The defect existing for prior art, the purpose of this utility model is to provide a kind of two safety sockets of opening that can overcome above-mentioned defect.
The technical scheme in the invention for solving the technical problem is: a kind of two safety sockets of opening, key is that described safety socket comprises shell, two can be inserted and jack that left and right struts support bar by plug, two cross seats and two electric contacts, described each jack support bar contains symmetrically arranged first and struts sheet and second and strut sheet, the first outer end that struts sheet is the insulation contact that is provided with collets, the second outer end that struts sheet is provided with moving contact, cross seat is arranged on jack support bar below, cross seat is provided with two contacts, be the first intersection contact and the second intersection contact, the corresponding setting of moving contact that bar is supportted with one of them jack in the first intersection contact, the second intersection contact is arranged between the insulation contact and an electric contact of another one jack support bar, two cross seats are arranged in a crossed manner each other.
Described first struts sheet and second struts between sheet and is provided with and leads an intermediate plate, leads an intermediate plate and is two and lead bit slice to folder, leads bit slice and first and struts sheet and second and strut the sheet angle that meets at right angles.
First of described jack support bar struts sheet and second and struts sheet and be provided with a horizontal connecting portion in upper end, described first struts that sheet and second struts sheet and horizontal connecting portion is integrated making structure, and described first struts sheet and second struts sheet upper end and be provided with arc-shaped transition district.
Described cross seat has fixed piece on earpiece.
Two contact structure of opening safety socket employing binary channel of the present utility model, and adopt the contact of integral type, must use the plug of suitable shape just can make inner transposition circuit connect, and be in another one connector assembly, to have the insertion of plug slice just can make whole circuit connect, have advantages of safe and manufacture craft is simple, rational in infrastructure.

Embodiment:
As shown in Figures 1 to 4, a kind of two safety socket of opening, safety socket comprises shell 1, two can be inserted and jack that left and right struts support bar 2 by plug, two cross seats 3 and two electric contacts 4, described each jack support bar 2 contains symmetrically arranged first and struts sheet 21 and second and strut sheet 22, the first outer end that struts sheet is the insulation contact that is provided with collets 23, the second outer end that struts sheet is provided with moving contact, cross seat 3 is arranged on jack support bar below, cross seat is provided with two contacts, be the first intersection contact 31 and the second intersection contact 32, the corresponding setting of moving contact that bar is supportted with one of them jack in the first intersection contact 31, the second intersection contact 32 is arranged between the insulation contact and an electric contact of another one jack support bar, two cross seats are arranged in a crossed manner each other.Described safety socket is provided with a shell, in shell, be provided with two jack support bar, two cross seats and two electric contacts, in an inserted sheet of plug is inserted into corresponding jack support bar time, the sheet that struts that inserted sheet supports jack in bar struts to the left and right, two strut sheet and outwards move, promote respectively the first contact and connect moving contact, make this jack support bar and cross seat conducting; And strut insulation contact and go to promote the second intersection contact and contact with electric contact, connect external circuit, two electric contacts and two energising totally 4 contacts, contact 51, two pairs of contacts coordinate, and realize the connecting and disconnecting to external circuit.
Described first struts sheet and second struts between sheet and is provided with and leads an intermediate plate 24, leads an intermediate plate and is two and lead bit slice to folder, leads bit slice and first and struts sheet and second and strut the sheet angle that meets at right angles.Lead the inserted sheet that an intermediate plate can make plug and keep correct position in inserting, ensure strutting effectively strutting of sheet, can also play one and block, prevent children misplug into.
First of described jack support bar struts sheet and second and struts sheet and be provided with a horizontal connecting portion 20 in upper end, described first struts that sheet and second struts sheet and horizontal connecting portion is integrated making structure, and described first struts sheet and second struts sheet upper end and be provided with arc-shaped transition district 25.Arc-shaped transition district 25 can make plug in inserting, reduce the resistance inserting.
As shown in Figure 5, the utility model can also be useful on the socket of tripod.
