Detailed Description

Referring to fig. 1 to 4, a waterproof structure of a wire includes a first wire 1 and a second wire 2, the first wire 1 and the second wire 2 being electrically connected through a PCB 4; the electricity junction cover is equipped with waterproof housing 5 of tube-shape, waterproof housing 5's one end is provided with encapsulating hole 6, and the other end is provided with first line hole 7, second wire rod 2 is installed in encapsulating hole 6, first wire rod 1 inlays the dress and is in first line hole 7, pass through in the waterproof housing 5 encapsulating hole 6 is filled with the waterproof glue, install closing cap 8 on the encapsulating hole 6, welding process seals the clearance between the stranded copper line of wire, and encapsulating process has sealed the wire and has draped over one's shoulders the clearance on layer outward, makes simply, the effectual waterproof effect that plays.

The wire comprises a lead 3 and an outer coating layer 9 covering the lead 3, the lead 3 comprises an insulating layer 301 and a conductor, the conductor is composed of a plurality of copper wires, a welding part 302 is arranged at the end part of the conductor, and the welding part 302 is connected with the PCB 4 through tin soldering.

The welding requires that the soldering tin completely covers the welding part, and air or water is prevented from entering the electric appliance through the gap of the copper wire to the maximum extent to cause damage.

And a strip-shaped through hole is formed in the middle of the PCB 4.

In this embodiment, there are two wires in the wire rod, PCB 4 corresponds to the quantity of wire is provided with corresponding electricity board that connects, during the soldering, the bar through-hole prevents effectively that same one side electrode from taking place the electricity because of the reason that soldering tin flows, guarantees one the wire only welds one connect on the electric board, avoid causing the condition of short circuit.

The inboard of closing cap 8 is provided with ring channel 10, increases closing cap 8 with the area of contact of waterproof glue prevents closing cap 8 drops, prevents that waterproof glue flows before solidifying waterproof shell 5 plays pleasing to the eye effect.

A second wiring hole 11 is arranged in the sealing cover 8.

In this embodiment, the first wire 1 is first inserted into the waterproof housing 5 through the first wire feeding hole 7, the soldering portion 302 on the first wire 1 is soldered to one side of the electrical board on the PCB 4 by means of soldering, the second wire 2 is then soldered to the other side of the electrical board on the PCB 4 by means of soldering after passing through the second wire feeding hole 11 of the sealing cover, and finally the connecting portion is completely stored in the waterproof housing 5, and the waterproof adhesive is filled through the filling hole 6 of the waterproof housing 5, the sealing cover is fixedly mounted on the filling hole 6, and the sealing cover is placed still until the waterproof adhesive is solidified.

The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
