ている（特公昭５３−７０３１号公報、実公昭５３−７
４３７号公報参照）。It is necessary to penetrate an electric conductor into the containment vessel of the reactor for the purpose of measurement, control and power supply of the reactor, etc. Airtightness is required to penetrate this partition to prevent leakage. Generally, an electric conductor penetrating device of this kind consists of a cylindrical housing with a metal flange to be welded by penetrating into a penetrating sleeve that is hermetically penetrated through a partition wall by welding or the like. It is mounted so as to penetrate in a gas-tight manner by sealing means provided at an interval so as to form an air-tight chamber in the middle of the housing. An epoxy resin is used as one of the conventional sealing means (Japanese Patent Laid-Open No. 50-1004).
No. 89), another prior art sealing means is such that a ceramic or glass sealing material provided between a tubular housing and an electrical conductor penetrating the tubular housing and this sealing material are embedded. It is made of rubber and a compound such as epoxy resin filled in a cylindrical housing (Japanese Patent Publication No. 53-7031 and Japanese Utility Model Publication No. 53-7).
437).

きないため多心化することができない欠点があった。However, there is a risk that the sealing means made of a sealing material made of epoxy resin may deteriorate in airtightness due to deterioration over time due to the difference between the thermal expansion coefficient of the electric conductor and the thermal expansion coefficient of the epoxy resin. Further, the sealing means composed of a ceramic or glass sealing material and a compound burying the sealing material,
Since the conductors must be connected on both sides of the sealant, it is necessary to connect the through conductors in the airtight chamber, the airtight chamber becomes longer, and the number of through conductors cannot be further increased, so that the number of cores is increased. There was a drawback that I could not.

信頼性の高い電気導体貫通装置を提供することにある。The object of the present invention is to avoid the above-mentioned drawbacks, to prevent deterioration over time, to have a small number of connection points, and to have a reliable electrical connection that can penetrate a conductor in an airtight manner without lengthening the airtight chamber. It is to provide a conductor penetrating device.

Two housings are joined and connected by an intermediate joint in an airtight chamber formed between the hermetically sealed parts,
This intermediate joint consists of a fixed sleeve that is attached to two housings via insulating spacers and slidably engages the conductor. The tubular housing extends parallel to the conductor from the airtight chamber and opens to the outside to form an airtight chamber. An electric conductor penetrating device having an airtightness detecting hole for detecting

Sliding and inserting into the fixed sleeve for connection does not lengthen the airtight chamber, and since each hermetic seal is formed separately in each of the two tubular housings, these tubular housings are hermetically sealed to each other. The airtight chamber can be easily formed between the two by simply joining them together. The thermal expansion and contraction of the conductor is absorbed by the intermediate joint.

May be attached to the glass hermetically sealed portions 18, 18 '. In this case, as shown in FIG. 4, the external lead wires 4 are formed such that the conductors 20 'adjacent to each other have different protruding lengths.
It is preferable to shift the connection portion 42 with 0. The connection with the external lead wire 40 is performed by bending the conductor 20 'outward and returning it to the original state. However, this work is easy and the connecting portions are displaced from each other, so that the outer diameter is prevented from increasing.

This is advantageous as the conductors 20 and 20 'have a smaller diameter. Further, when a large number of conductors 20 and 20 'are penetrated, the conductor interval is narrowed and the insulation is deteriorated. In that case, it is also effective to partially remove the outer cladding layer. Further, in each of the above-described embodiments, ceramic can be used in place of glass as the hermetic seal portion.

ることができる実益がある。According to the present invention, as described above, the conductor to be penetrated has the connecting portion of the intermediate joint in the hermetic chamber, but this intermediate joint has two parts.
Since it is formed in an airtight chamber that is divided and joined to each other, it can be easily formed, and since the conductor is slid and inserted into the fixed sleeve to connect it, the airtight chamber is not lengthened, and the intermediate joint Consists of a fixed sleeve that is slidable with respect to the conductor, so it can be formed without lengthening the airtight chamber and can absorb the thermal expansion and contraction of the conductor.
Further, since each hermetic seal portion is formed separately in each of the two tubular housings, the airtight chamber can be easily formed only by joining the tubular housings to each other in an airtight manner. Further, since the airtightness detecting hole, which is the airtightness detecting means, extends in parallel with the conductor inside the housing, there is a merit that the diameter of the hanging does not increase and the overall size can be made compact.
