Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail, but they are not to further restriction of the present invention.
As shown in Figures 1 to 6, metal contact element provided by the invention, it comprise make contact to the first metal contact element 1 used and the second metal contact element 2, first metal contact element 1 and the second metal contact element 2 are provided with functional contact section and both contact time produce the electric arc recurring structure of electric arc.
Arcing generating region, region when the electric arc recurring structure 11 of the first metal contact element contacts with the electric arc recurring structure 21 of the second metal contact element; When the functional contact section 12 of described first metal contact element contacts with the functional contact section 22 of the second metal contact element, region forms functional contact district.
The end of the second metal contact element 2 is provided with the second insulator 23 for making the first metal contact element end be in upward state; The upper surface of described first metal contact element 1 is provided with the shell fragment 3 controlling its end return, one group of stage clip 32 of shell fragment 3 is provided with the first insulator 31 for isolating electric arc generating region and functional contact district.
Be provided with the control at the process electric arc inserted and extract of the high-voltage electric connector of this metal contact element, first metal contact element 1 and the second metal contact element 2 are when plugging, shell fragment 2 and the second insulator 23 is utilized to control rising and the return of the first metal contact element 1, and utilize the second metal contact element 2 upper groove 24 simultaneously, the electric arc produced in electric arc generating region when the first insulator 31 moved to during plug in groove 24 contacts with the electric arc recurring structure 21 of the second metal contact element the electric arc recurring structure 11 of the first metal contact element is isolated and eliminates, eliminate electric arc easily with satisfied plug simultaneously.
In implementation process, the cambered surface that the functional contact section 11 of the first metal contact element can be an arc surface or be made up of some parallel curved metal bar lower surfaces.
In implementation process, the electric arc recurring structure 11 of the first metal contact element and the electric arc recurring structure 22 of the second metal contact element can be an arc convex or a fin.
In implementation process, the first insulator 31 adopts the mode of plastic packaging to be arranged on the stage clip 32 of shell fragment 3.
In implementation process, the second insulator 23 adopts the mode of plastic packaging to be arranged on the end of the second metal contact element 2.
As shown in Figures 1 to 5, will to contact in insertion the first metal contact element 1 and the second metal contact element 2 below and be described with extracting to contact:
Insert contact process: when the second metal contact element 2 moves to the first metal contact element 1 head left, the head of the first metal contact element 1 is raised by the second insulator 23 on the second metal contact element 2, at this time the first metal contact element 1 and the second metal contact element 2 do not produce electric arc or electric arc very little on contacting, when the second insulator 23 moves to first insulator 31 time, first metal contact element 1 is still in the state of lifting, functional contact section on first metal contact element 1 and the second metal contact element 2 does not all come in contact, electric arc is not at this time almost had to produce, when the electric arc recurring structure 11 of electric arc recurring structure 21 and the first metal contact element that the second metal contact element 2 moves to the second metal contact element carries out contacting time, at this time electric arc can be produced and the functional contact section 12 of the first metal contact element has sunk down into functional contact district contacts with the contact-segment 22 of the second metal contact element, the electric arc at this time produced is isolated by the first insulator 31 being positioned at groove 24, thus realize protecting the functional contact district of the first metal contact element 1 and the second metal contact element 2.
Extract contact process: time the second metal contact element 2 moves right the electric arc recurring structure 11 of the first metal contact element, when the electric arc recurring structure 11 of the first metal contact element lifted by the second insulator 23 on the second metal contact element 2 time, at this moment the first metal contact element 1 is separated with the functional contact district of the second metal contact element 2, the contact-making surface be separated does not produce electric arc or electric arc very little, when the second insulator 23 moves to first insulator 31 time, first metal contact element 1 is still in the state of lifting, the electric arc recurring structure 11 of the first metal contact element and the electric arc recurring structure 21 of the second metal contact element still can not come in contact, electric arc is not at this time almost had to produce, when the second metal contact element 2 move to do not contact with the first metal contact element 1 time, at this time the first metal contact element 1 resets under the pressure effect of shell fragment 3, complete the first metal contact element 1 to affranchise state, ensure when extracting, do not have electric arc between first metal contact element 1 and the second metal contact element 2 to produce, or electric arc can cool rear extinguishing fast.
As shown in Figure 2, first metal contact element 1 and the second metal contact element 2 are when being in half plug state, at this time the first metal contact element 1 is in ascent stage under the effect of shell fragment 3, just there is time and the height of uphill process in this, this height joins with the plastic packaging height correlation of the first insulator 31 on the plastic packaging height of the second insulator 23 on the second metal contact element 2 and shell fragment 3, and the speed of plug associated with the rise time of the first metal contact element 1.
As shown in Figure 3, first metal contact element 1 and the second metal contact element 2 are when being in the state of extracting, at this time the first metal contact element 1 is in decline and reseting stage under the effect of shell fragment 3, just there is time and the height of reseting procedure in this, the plastic packaging height correlation of the first insulator 31 on the plastic packaging height of individual height and the second insulator 23 on the second metal contact element 2 and shell fragment 3 joins, and the speed extracted associated with the resetting time of the first metal contact element 1.
