Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the field of lightning nectar, electrical nectar suitable for being submerged in liquid and used in an IC state.

According to the prior art, moisture-resistant electrical connectors are widely used in the prior art.
Fumikawa has been used, and is generally a hard Plus Book body.
The combination of 414A and 414A is used to form a 41 seal to prevent contaminants from causing corrosion of electrical connections.

For example, in No. 3, 594, 696,
An electrical terminal connector assembly is described having a hollow housing and two electrical terminals connected to insulated wires held within openings formed in the housing. The entirely hollow housing contains a molded bullet with a terminal embedded inside. This mass of material extends beyond the open end of the housing and forms a voluptuous sealing lip to which the connector also connects to the septacle. The resilient material is also limited to the portion of the terminus and wire that extends beyond and through the end of the housing.1. : Forms a moisture seal. - Contour molded. This prior art 21 nectar has a function that helps prevent air-borne moisture and contaminants from leaking into the terminal; When using the submerged condition C, the electric wire is formed around the electric wire, and it is close to a lump. be.

", 937, 54.5 ;': The waterproof electrical connector described in ``Lightning F6! rx+r; It is pushed into the associated first 731 seal connector housing until the terminal is pushed out to a depth that secures the terminal lug in place.
The issue is neck IT! Since the diameter of I'-'E is smaller than the inside diameter of the connector housing, it will be compressed when inserted into the housing, and the distance between the inner surface of the nectar housing and the outer surface of the annular stopper will be reduced. Inner surface of hole and wire insulation H
A watertight seal is formed between the outer surfaces of the Removal C
A round plug is used to lock the catch in place relative to the terminal, preventing the terminal from being removed axially from the connector. This electrical connector is effectively sealed so that the 13: plug is submerged in water.
b Is it 1J11t to prevent moisture from entering the plug?
Assembling technology increases nectar = 1 stroke J, U4
It involves the need for a few tasks.

1.Practice of the Invention The present invention utilizes a relatively inexpensive manufacturing method to obtain a waterproof electrical nectar that is properly sealed against moisture contamination and that cannot be submerged in water. The purpose is

According to the present invention, a perforated annular stopper R made of J lastomer such as silicone is placed on the insulated wire near the electrical terminal pull, and this assembly is placed inside the molded product to obtain a waterproof electrical connector. . The hole in this retaining ring has a diameter smaller than the diameter of the normal type I, so that a seal is formed that conforms to the weather conditions placed on the insulation of the wire. The molded body is in contact with the end face of the retaining ring, and the longitudinal movement of 1 is Fll +1. ,L,

Electricity of the present invention = -1 nectar [Jεi! As shown in Figure 1, this is applied to both the Type 1 electrical connectors 10 and 11 and the Type 11 electrical connectors/10.

The t111 type connector 10 has a conductor U (hard τT seal 12 injection molded around the type terminal 18).
, and the terminals are permanently crimped or welded to the corresponding Wye X 114, as well as to the insulation sheath 16. The electrical terminal 18 is made by Tsutomu, a molded plate, and a closed-shaped 411-type 1 second contact portion 20 extending from the housing 12 to the end portion 22. Than)? ) Splint 14
- It is formed by forming one part with a diameter for closing the monthly charge. A retaining ring 15 made of silicone 41 bullet 11 elastomer 7 is placed on the electrical terminal 18'fJ, and an insulator 1G of wire A714 passes through the shell and marks the extension hole 13. The hole 13 of the retaining ring 15 has a maximum diameter smaller than the diameter of the insulator 16, and the hole 13 of the retaining ring 114 receives the insertion of the wire insulator 16. We must stretch and expand it. Further, a circumferential rib 17 is formed on the outer peripheral surface of the retaining ring 15 to increase the length of the outer surface and provide additional fixation and sealing.
