させ、且つ加熱処理に供さしめる。[Function] Lead wires covered with soft polysalt 1-hibinyl material,
After inserting the terminal with the terminal fitting attached into the cavity of the connector housing made of hard polyvinyl chloride, the lead wire receiving part is held between the electrodes of the high-frequency heating machine installed above and below the part. The material is compressed in the soaked state and subjected to heat treatment.

全周に渉って密着する。At this time, the surface of the electrode that holds the lead wire reception part is recessed at a location corresponding to the part where the lead wire is located, and as a result, the lead wire reception part is pushed toward the center in the radial direction. It is compressed and tightly adheres to the lead wire covering and its entire circumference.

しかして当該部分に水密性が確保される。Thus, watertightness is ensured in that part.
［実施例］ 以下、本発明実施の一例を図面に基づいて説明する。[Example] Hereinafter, an example of implementing the present invention will be described based on the drawings.

熱に供さしぬる。First, a lead wire (1) covered (2) with a soft polyvinyl chloride material is attached to a terminal fitting (3), and a connector housing (4) made of a hard polyvinyl chloride material is attached. into the cavity (5). (See Figure 1) Next, the lead wire reception part (6) is connected to a pair of electrodes (7) (7"

(See Fig. 3) [Effect J] As is clear from the above-described embodiments, the present invention eliminates the above-mentioned conventional drawbacks ① to ②, and further improves the relationship between the connector housing and the terminal fittings by reducing the lead wire receiving portion. This can also be guaranteed by the integral relationship between the lead wire and the lead wire sheath.

The connector does not need to be heat resistant like the one used in the engine room of a passenger car, and therefore polyvinyl chloride, which has poor thermal stability, can be used as the material for the lead wire sheath and the connector housing.
