Embodiment

Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.

For the ceramic insulator of medicine equipment, there is body 6, body 6 adopts the aluminium oxide ceramics of 90%-95% to make, and the end face A of body 6 is laid with sector 2 and is shaped with bar-shaped trough 3 between adjacent sector 2 adjacent side, and the degree of depth and the width of bar-shaped trough 3 are 1-1.5mm.The arc surface of the little head end of sector 2 surround deep-slotted chip breaker 5 and deep-slotted chip breaker 5 and bar-shaped trough 3 through, the external diameter of described deep-slotted chip breaker 5 is 5-7mm, the degree of depth is consistent with the degree of depth of bar-shaped trough, bar-shaped trough 3 and deep-slotted chip breaker 5 are for isolating 5 uniform sectors 2, prevent the metal layer 7 on sector 2 from conducting electricity under equipment working state, cause equipment short circuit.Described sector 2 is provided with the stepped hole 1 axially running through body 6, and specifically, stepped hole 1 is positioned at sector 2 center, and is 2-2.5mm near the aperture of end face A, and the aperture away from end face A is 4-5mm.Metal layer 7 is shaped with in the middle part of the external peripheral surface of described body 6, body 6 external peripheral surface near end face A is shaped with glaze layer 8 and leaves gap between glaze layer 8 and metal layer 7, described sector 2 is also provided with metal layer 7, described metal layer 7 is molybdenum manganese metal layer and nickel dam two parts composition, first at body 6 surface sintering molybdenum manganese layer, then plate nickel dam, the width of body 6 external peripheral surface metal layer 7 is 6-10mm; Body 6 and end face I junction are shaped with the conical surface 4, and the conical surface 4 is also shaped with glaze layer 8, and the glaze on glaze layer 8 is the high-temperature glaze of more than 1400 DEG C.

Body 6 surface is through processing process, and surface roughness reaches less than 1.6 microns, then completes the processing of metal layer 7 in body 6 middle part, and body 6 external peripheral surface and the conical surface 4 of close end face A complete the processing that glazing, glaze firing and hydrogen burn; End face A and the glaze layer 8 of ceramic insulator are exposed in atmospheric environment, glaze layer 8 can effectively avoid water, gas and other pollutant to the erosion of body 6, metal lead wire on Medical Devices penetrates the end face B arriving body 6 from the small bore end of shoulder hole 1, metal lead wire welds with the metal layer 7 on sector 2, the metal layer 7 of body 6 external peripheral surface makes end face B place under vacuum conditions after welding with other parts on Medical Devices, electric current is introduced vacuum environment from atmospheric environment by metal lead wire, thus Medical Devices are worked normally.
