Field of the Invention The present invention relates to an electric / electronic component assembly comprising a connector and a covered electric wire, and more particularly, to a liquid such as water or oil from outside which is prevented from entering a circuit system. The present invention relates to a so-called waterproof connector and an assembly composed of electric wires.

However, since they can be repeatedly attached and detached easily and the circuit reliability is high, etc. An assembly in which a connector is attached to one end or both ends of an electric wire is widely used. In such an assembly, in order to maintain the function of the electric circuit for a long period of time, it is necessary to shut off the circuit system from the outside and prevent the intrusion of a liquid such as water or oil.

着忘れが起きる危険もある。For this purpose, it is first necessary that the electric wire is covered with a sufficiently reliable material. Soft vinyl chloride resin is widely used as a coating agent. The other component, the connector, also uses a highly reliable insulating material. Specifically, polyamide, PET, PBT, modified PP
E, a material obtained by adding a stabilizer, a reinforcing agent, a flame retardant, and the like to a liquid crystal resin or the like is used. However, when the wire and the connector are connected, even if the hole diameter of the connector and the outer diameter of the wire coating are finished with high precision, fluid such as water does not enter through the gap between the connection portions (locking portions). Inevitable. For this reason,
The portion is filled with a flexible material such as rubber, elastomer, or soft plastic as a sealing material to prevent liquid from entering. As the sealing material, highly durable synthetic rubber such as nitrile rubber, silicon rubber, chloroprene rubber, and various elastomers such as polyurethane, polyester, and polyamide are used. However, according to this method, it is necessary to attach a seal each time the electric wire is locked to the connector, and the number of parts increases. For this reason, not only is it disadvantageous in terms of cost, but also a great burden is imposed on the assembling work, and in the worst case, there is a danger that the user may forget to attach it.

った。For this reason, as shown in FIG. 1, a connector has been devised in which a film-like gel-like material (3) is arranged on the wire mounting side of the wire locking portion (2) of the connector (1). When an electric wire is inserted into this connector, the gel film (3) is broken and the electric wire can be mounted. A terminal is attached to the end of the electric wire in advance. Needless to say, the gel film (3) is adjusted in advance to an appropriate film strength, plasticity, and viscosity so that the terminal can be attached. When a large-diameter electric wire is attached, a pilot hole or cut may be made in the gel film to guide the terminal. When the end of the electric wire is attached, the gel film adheres to the outer periphery of the electric wire coating (4) due to the elasticity of the gel film (3) as shown in FIG. The sealing property is developed. By using such a gel film as a sealing material, the work of connecting and assembling the connector and the electric wire can be remarkably streamlined.

Variations in terminal shape and dimensions can be absorbed. Specifically, it is a silicon resin swollen with a liquid silicon compound. As the silicone resin, a crosslinked polymer of polyorganosiloxane is used.

Attempts were made to obtain satisfactory sealing properties. However, when the wire of the assembly that had been left at 90 ° C. for 2 weeks was bent 1000 times, cracks were observed on the coating surface. The occurrence of cracks means that the properties of the vinyl chloride resin-coated material have changed, and such a connector wire assembly cannot withstand long-term use. It is conceivable that the properties of the gel film may change depending on the type of the electric wire, and the sealing property may decrease.

た。Means for Solving the Problems The present inventor has made intensive studies to solve the above-mentioned problems. First, the reason why the above-mentioned vinyl chloride resin coating material deteriorates in a high-temperature atmosphere was investigated. As a result, it has been clarified that a plasticizer such as dioctyl phthalate, which is generally blended as a plasticizer in the soft vinyl chloride resin coating material, has an effect.
That is, the plasticizer such as dioctyl phthalate and the liquid polysiloxane in the silicone gel of the sealing material are compatible with each other,
In particular, this phenomenon is promoted in a high-temperature atmosphere, and eventually the strength of the coating material is deteriorated. Further, based on this discovery, further studies were conducted, and it was found that the SP value of the plasticizer in the vinyl chloride resin coating material was important. In short, the content of the plasticizer having an SP value of less than 9 could be suppressed. They have found that they are effective and have completed the present invention.

When used as an assembly with a connector for a long time, the change in physical properties becomes remarkable. As a result, when an external force such as vibration or deformation is applied to the electric wire system, the coating is broken. This is considered to be due to the mutual movement of the plasticizer contained in the coating material and the liquid silicon in the gel.Therefore, it is presumed that the properties also change on the gel side and the sealing ability decreases.

Some types of device-side connectors have terminals mounted directly on the board. In this case, since the connection is made directly without passing through an electric wire, there is no problem to be solved by the present invention. On the other hand, in a connector of the type in which the inside of the device is wired by electric wires, it is necessary to seal between the connector and the internal wiring wires.
The assembly of the present invention can be applied to the connector engaged with the electric wire inside the device without any problem.
