いる。A conventional example is shown in FIG. That is, 1 is the core, 2
is the main conductor, 3 is the tulip contact, 4 is the terminal, 5
is an upper metal fitting, 6 is an insulator tube, and the main conductor 2 and the terminal 4 are connected by a tulip contact 3. This tulip contact 3 has a rounded structure as a whole to alleviate the electric field, and one end is fixed to the main conductor 2' to prevent its own position from shifting, and the terminal 4 is attached to the tulip contact 3. Connected by inserting a slide.

意が必要であり、加工精度を高くする必要があるといっ
た欠点があった。However, this tulip contact 3 has a complicated shape and requires a large number of contact points, and furthermore, in order to give it a rounded shape (after assembly), processing precision is required, making it expensive. Also terminal 4
When sliding it into Tulip Contact 3,
Since a reaction force is applied to the main conductor 2 side, it is necessary to firmly fix the terminal 4 and the main conductor 2 together. Furthermore, since the tulip contact 3 has little margin in the lateral (radial) direction, care must be taken in aligning the terminal 4 and the tulip contact 3 during assembly, and processing accuracy must be increased.
したがって、この発明の目的は、加工精度および強度が
さほど必要でなくしかも組立が簡単なブッシングを提供
することである。Therefore, it is an object of the present invention to provide a bushing that requires less processing precision and strength and is easier to assemble.

内に充填されたガス、油等の絶縁物である。An embodiment of this invention is shown in FIG. That is, the lower end of the funnel-shaped shield 8 is attached to the tip of the main conductor 7 in a penetrating state, and the upper end 8a of the shield 8 is brought close to the height position of the lower end 9a of the terminal 9. Further, one end of the main conductor 7 and the lower end of the terminal 9 are connected by a flexible wire 10 such as a braided wire, and the wire is mostly housed within the funnel-shaped shield 8. 1 is a main body of the device, 12 is an insulator tube, and 13 is a lower flange attached to the main body 11 of the device. 14 is an upper flange, 15 is an upper metal fitting attached to the upper flange 14,
The terminal 9 is provided. 16 is the core, 17 is the insulator tube 12
It is an insulator filled with gas, oil, etc.

影響がない。With this configuration, the main conductor 7 supports and fixes the shield 8 and the flexible lead wire 10, so it has a lighter fixed structure than the conventional tulip contact 3, and its strength can be reduced. Further, the shield 8 can be made simple, such as in the shape of a funnel, and the flexible lead wire 10 is also inexpensive, making it very economical. Furthermore, since the flexible lead wire 10 connected to the main conductor 7 can be slackened within the shield 8, the other end of the flexible lead wire 10 can be attached to the lower end 9a of the terminal 9.
It can take enough working space length to connect to. Moreover, after connecting the flexible lead wire 10, the upper metal fitting 15
can be attached to the upper flange 14. Furthermore, since the flexible lead wire 10 is housed within the shield 8, it is not affected by the electric field.

簡単で安価になるという効果がある。As described above, the bushing of the present invention connects the conductor and the terminal with a flexible lead wire, and the conductor is provided with a shield that alleviates the electric field of the flexible lead wire, so it is easier to process than the conventional bushing. It has the advantage that accuracy and strength are not required so much, and the installation work is simple and inexpensive.
