体１２上に設けたものが提案されている。 As shown in Figures 1 and 2, a conductive electrode ball 24 (iron, copper, aluminum, etc.) is placed inside a rubber or plastic insulator 22 (crosslinked polyethylene, EP rubber, etc.). ) is provided on the protruding cable insulator 12.
なお、１０はケーブル導体、１４はケーブルし
やへい層を示す。 Note that 10 indicates a cable conductor, and 14 indicates a cable shear layer.

などの優れた性質を持つている。 The connection section configured as described above has the following features: 1 Electrostatic capacitance is distributed in the reinforcing insulator 20 in the radial direction and axial direction by the electrode balls 24, and the capacitance is distributed between the cable conductor 10 and the cable. The voltage between the thin layers 14 is shared. 2. Appropriate capacitance can be designed using the electrode bulbs 24, so the connecting part can be made smaller. 3. Since the electrode bulbs 24 are used, the connection part can be made smaller. However, it has excellent properties such as being unable to form electrically steep electric fields.

特徴とする。 In this invention, the insulator 22 of the reinforcing insulator 20 is
It is characterized by being made of a shrunk heat shrink tube.
この熱収縮チユーブは、たとえば次のようにし
て作られる。 This heat shrink tube is made, for example, as follows.
１ 公知のラム式押出し機の中に電極球２４を入

熱して収縮させる。収縮させた後の状態は、「第
１図」および「第２図」と同じである。 These heat-shrinkable tubes containing the electrode balls 24 are
It is placed over the terminal and intermediate cable insulators 12 and heated and shrunk using hot air, an electric heater, or the like. The state after deflation is the same as in "Fig. 1" and "Fig. 2".
考案の効果
電極球入りの熱収縮チユーブを収縮させたと
き、電極球２４の位置が変化する。しかし、その
とき、電極球自体が変形するのではない。Effects of the invention When the heat-shrinkable tube containing the electrode bulb is shrunk, the position of the electrode bulb 24 changes. However, at that time, the electrode sphere itself does not deform.
本願考案の場合、コンデンサコーンの性能は、

終端部を得ることができる。 In the case of the present invention, the performance of the condenser cone is
This depends on the capacitance formed between the electrode balls and between them and the cable conductor, so by calculating the amount of shrinkage in advance, even if you try to improve workability by using a heat shrink tube, the characteristics will be sufficiently excellent. It is possible to obtain a terminal end with a
これに反して、電極が箔の場合は、収縮したと

中にあらかじめ入れておくようなことはできな
い。 On the other hand, if the electrode is made of foil, it will wrinkle when it shrinks, so it cannot be placed in a heat shrink tube beforehand.
すなわち、電極球であるからこそ、熱収縮チユ
ーブの中に入れておくことができるのである。 In other words, because it is an electrode ball, it can be placed inside a heat shrink tube.
