[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figures 1 to 5As shown, the cable extension line with waterproof photovoltaic connector assembly of the utility model includes a first connection assembly 1 and a second connection assembly 2, and the first connection assembly 1 and the second connection assembly 2 are connected by a threaded structure. The connection member 23 in the first connection assembly 1 is provided with an external thread, and the connection member 23 in the second connection assembly 2 is provided with an internal thread 22, and the connection between the first connection assembly 1 and the second connection assembly 2 is achieved by the cooperation of the internal thread 22 and the external thread. The structures of the first connection assembly 1 and the second connection assembly 2 are the same, except that the internal thread 22 and the external thread part 21 are used for connection. The two wire bodies 3 can be connected.

[0024] When the wires 3 are connected, a connection terminal is provided between the first connection component 1 and the second connection component 2 for mutual plugging, so that the two wires 3 can be connected. Then the rear end part of the wire 3 is waterproofed.

[0025] The first connecting component 1 is provided with a connecting member 23, a pushing member 4 and a waterproof member 5. The connecting member 23 is provided with a mounting portion 6 for accommodating the waterproof member 5. A waterproof chamber 7 is provided in the middle of the mounting portion 6. A first wire hole 8 for accommodating a cable is provided in the middle of the waterproof member 5. The pushing member 4 is provided with a pushing body 9, which pushes the waterproof member 5 toward the connecting member 23.

[0026] The waterproof member 5 is a conical disk, and is made of metal material. The waterproof member 5 has a certain plasticity and can be deformed by external force.

[0027] A sealing member 10 is sleeved on the outer wall of the waterproof member 5. The sealing member 10 is made of rubber material and has a mounting groove 11 in the middle thereof. The sealing member 10 is composed of a fixing portion 24 and a ball head 12. A protrusion 13 is provided on the inner wall of the waterproof chamber 7, and the protrusion 13 cooperates with the ball head 12.

[0028] The waterproof member 5 is provided with a thickened portion 14, which faces the connecting member 23. The thickened portion 14 is used to contact with the inner wall b surface of the waterproof chamber 7 to prevent the waterproof member 5 from excessive deformation.

[0029] The waterproof member 5 is provided with a matching body 15, which is composed of a first connecting portion 16 and an arc-shaped portion 17, and an arc-shaped opening 18 is formed in the middle of the arc-shaped portion 17. The pusher 9 is composed of a second connecting portion 19 and a pusher end 20, and the pusher end 20 has a circular cross section, and the pusher end 20 is placed in the arc-shaped opening 18. The pusher end 20 has a circular cross section and can rotate in the arc-shaped opening 18, so when the pusher end 20 pushes the arc-shaped portion 17, the pusher end 20 can be kept rotating in the arc-shaped opening 18, so that the middle of the waterproof member 5 moves toward the b surface.

[0030] A threaded portion 21 is provided on the mounting portion 6 , and an internal thread 22 matched with the threaded portion 21 is provided on the pushing member 4 .

[0031] like Figure 4 As shown, the inner wall surface of the first wire hole 8 in the waterproof member 5 is a parallel surface. When the waterproof member 5 is deformed, the parallel surface will be inclined, so that the edge a is inserted into the skin of the cable to form a seal. The outer wall and the inner wall of the waterproof member 5 are sealed to prevent external water vapor or dust from entering the connection of the wire body 3, thereby improving the conductivity of the cable connection part.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
