Abstract
The present invention relates to a waterproofing device for a wire cable.
The present invention is characterized in that when a waterproofing means is inserted into an electric wire cable to which a connector for connecting an electronic device and an electronic device is coupled so as to prevent moisture from penetrating into the electric wire, And the wire cable are melted by inserting the wire and the plurality of core wires are fused so as to be watertightly sealed together with the plurality of core wires so as to be reinforced between the core wire of the wire cable and the plurality of core wires, It is possible to prevent an occurrence of disconnection between the outer shells of the cable.
Description
BACKGROUND OF THE
Generally, when connecting various electronic devices or electronic devices, the cable is connected to one side and the other side by a wire cable having a connector. Here, the wire cable is coated with a plurality of core wires each covered with an insulator on the inside thereof, , The connector is detached from the outer surface of the wire cable and is coupled to the ends of a plurality of stripped core wires.
The plurality of core wires of the wire cable to which the connector is coupled are left in a state in which the portion not connected to the connector is long exposed, so that there is a large difference in strength between the connector and the wire cable not exposed. The wire is wrapped around the exposed plurality of cores with a separate tape or the tube is inserted to reinforce the strength to protect it from external force.
However, when the cable is used to connect to an electronic device or an electronic device installed in a room, it is not necessary to use it. However, it is connected to a security camera or signal lamp installed outside the vehicle, , Water caused by snow, rain, or moisture due to climate change flows along a plurality of exposed core wires to cause a short circuit into the interior of the cable or connector due to exposure to the external environment .
In order to solve the above problems, according to the Korean Patent Registration No. 10-1526179 (name, a waterproofing device for wires using a wire holder) (prior art), a plurality of electric wires Inserting a wire holder made of a thermoplastic hot-melt adhesive and inserted into a heat-shrinkable tube which is thermally welded to the outside of the wire holder and the plurality of wires outside the wire holder to melt the wire holder and the heat-shrinkable tube, The holder allows the enclosure to permeate between the plurality of electric wires from which the enclosure has been molten so that no space is formed between the plurality of electric wires, thereby preventing water from penetrating and preventing a shot due to moisture.
However, when the wire holder and the heat-shrinkable tube that enclose the plurality of wires are thermally welded to each other, the wire holder is inserted into only a part of a plurality of wires from which the sheath is detached, The molten wire holder is only partially solidified by being penetrated by the heat-shrinkable tube to only a part of the plurality of electric wires and the exterior part.
Thus, in the prior art, only a part of the wires is solidified between the wires and the jacket, so that a plurality of electric wires in which the jacket is peeled are maintained in a large number of non-solidified wires and the jacket, The molten wire holder is rubbed by pressing the heat-shrinkable tube so that the molten wire holder is uniformly spread between the plurality of wires and the outer portion, so that the molten wire holder is uniformly spread over a plurality of wires It has been flattened to float and solidify the whole, and has been waterproofed.
However, even though the above-mentioned conventional technique works to spread evenly while rubbing the wire holder to be melted, the melted wire holder does not penetrate to the end portion where the outer portion of the plurality of wires is not melted, The unsealed end portion has a strength that is weaker than other portions where the wire holder seeps into the solidified portion, so that even if a small external force acts, disconnection occurs relatively easily.
In order to solve the above-described problems, it is an object of the present invention to provide a waterproofing device, in which waterproofing means is inserted into a plurality of core wires from which a sheath has been stripped, Thereby preventing water from being cut between the plurality of core wires from which the sheath is removed and the outer surface of the end portion of the cable cable.
According to a preferred embodiment of the present invention, a plurality of core wires are covered with an outer sheath, a plurality of core wires formed in a cylindrical shape and having a plurality of core wires from which outer sheaths of the wire cables are stripped, A plurality of core wires, a plurality of core wires, a plurality of core wires, a plurality of core wires, and a plurality of core wires, Wherein the waterproofing means comprises a recessed surface in which the outer surface of the wire cable is recessed with a plurality of core wires from which the outer skin is detached to the inner peripheral wall of the insertion groove, A plurality of through holes penetrating through the other side of the core wire are formed in the outer surface of the outer casing, And a plurality of core wires inserted into the center of the cable cable end portion protruding from the center of the bottom surface in a direction opposite to the penetration direction of the through- And a contact protrusion for adhering the outer skin to each other.

The effect of the present invention according to the above-described solution is that when a waterproof means is inserted into an end of a wire cable to which a connector for connecting an electronic device and an electronic device is coupled so that moisture does not penetrate outside, The plurality of core wires and the wire cables are fused so as to be waterproof together by inserting and melting a plurality of core wires of the coupled wire cable and the inner and outer wires of the wire cable, Since the thickness between the outer shells is reinforced, it is possible to prevent the occurrence of disconnection between the plurality of core wires and the outer surface of the end portion of the cable cable.
