Safe operation and control play an important role.Usually there is high temperature, humidity, persistent erection, γ irradiation etc. in the working environment of ionisation chamber
Unfavorable factor, is the small-signal of transmitting ionisation chamber, and generally use rigid inorganic cable carries out ionisation chamber prime signal and draws
Go out.
The dielectric of rigid inorganic cable is usually the materials such as magnesium oxide powder of high temperature resistant, radiation resistance, high resistivity,
Such dielectric exposure is easy absorption aqueous vapor and makes moist in air, and making moist can cause insulation performance to degenerate, and then influence signal
Transmission, therefore rigid cable terminal is typically fabricated as the structure of insulated enclosure, prevents that cable from making moist and insulation resistance declines.At present
Market technical solution generally first carries out rigid cable-glass glaze sealing or rigid cable-ceramic insulator welded seal, then
Cable is connected with ionisation chamber press seal.The mode poor reliability of press seal connection, it is limited to the protecting effect of cable.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of rigid cable connector, this skill
Art scheme can avoid dielectric absorption steam from making moist, and ensure that cable is safe to use.
The technical solution of the utility model is as follows：
A kind of rigid cable connector, including cable, lantern ring, sheath, ceramics insulator and kovar cap；
The dielectric and be arranged in the insulation that the cable includes center conductor, is arranged outside the center conductor
The cable jacket of medium outer layer；
The lantern ring is sleeved on the cable jacket and is welded with the cut cable face ring and sealed；
The sheath is sleeved on the lantern ring and is fixedly connected with the lantern ring；
Described ceramics insulator one end is stretched into the sheath, and the other end is connect with the kovar cap；
The center conductor of the cable passes through the ceramics insulator and is welded with the kovar cap.
Further, above-mentioned rigid cable connector further includes being set between the ceramics insulator and the sheath
Cut down ring.
Further, above-mentioned rigid cable connector, in the gap between the ceramics insulator and the center conductor
Filled with magnesium oxide powder.
Further, above-mentioned rigid cable connector, described lantern ring one end are concordant with the cable jacket end face of the cable
And the two boxing seals, the lantern ring other end is provided with to the convex edge extended far from cable axis, and the sheath is welded in institute
It states on convex edge.
The beneficial effects of the utility model are as follows：
The utility model is used for the connection of rigid cable and ionisation chamber flange, and simple in structure, air-tightness is good, insulation performance
It is good, it is easy to implement, it can effectively solve the problems, such as that rigid cable dielectric is easy to make moist, while lantern ring has carried out stress release,
Rigid cable stress is avoided to bend, effective protection rigid cable improves reliability and the service life of ionisation chamber and rigid cable.
