Description

Technical Field

[0001] The utility model relates to the technical field of butt joint equipment, in particular to an extension line butt joint. Background Art

[0002] The extension cord connector is a connector used in photovoltaic power stations. It consists of a plug, a socket, and a cold-pressed terminal. When in use, the cable is crimped onto the cold-pressed terminal and then inserted into the plug and the socket. The plug and socket are plugged and fixed to form a docking connection. This docking method requires the cold-pressed terminal to be crimped on the cable. Special cold-pressing tools or other connection tools are used during installation, which requires more tools and operating steps, and is inconvenient to install. For this reason, we propose an extension cord connector. Utility Model Content

[0005] (II) Technical solution

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The extension cord connector includes a socket and a plug that are plugged into each other. The plug is also provided with a connected plug-in copper tube and a docking frame. A pair of sliding clamps are provided in the docking frame. The sliding clamps slide along the radial direction of the plug-in copper tube and clamp the wire core of the extension cord to form a clamp in the plug-in copper tube. A wedge block is also installed on the socket. When the socket and the plug are plugged in, the wedge block squeezes and pushes the sliding clamp to slide relatively and against the wire core.

[0008] Furthermore, the sliding clamping member includes a slider, a protrusion, and an arc-shaped member. The protrusion is installed on the upper and lower sides of the slider, and the arc-shaped member is located on the side of the slider.

[0009] Furthermore, slide grooves are provided on the upper and lower inner walls of the docking frame, and the protrusions slide along the slide grooves.

[0010] Furthermore, the other side of the sliding block is wedge-shaped and corresponds to the section of the wedge block.

[0011] Furthermore, recessed grooves arranged along the direction of the plug are provided at the edge positions on both sides of the docking frame.

[0012] Furthermore, the plug is also provided with protruding claws, which are inserted into the fixing holes of the socket to form a plug-in fixation.

[0013] (III) Beneficial effects

[0014] The embodiment of the utility model provides an extension wire to a connector. It has the following beneficial effects:

[0015] 1. By setting the wedge block and the slider, the wedge block presses against the slider and slides along the docking frame toward the center of the plug and clamps the wire core. When the socket and the plug are connected, the wire core is fixed and clamped, eliminating the need for crimping with tools and simplifying the installation steps. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See attached Figure 1-7 , the extension cord connector includes a socket 1 and a plug 2 that are plugged into each other, and the plug 2 is also equipped with a protruding claw 21, which is plugged into the fixing hole 11 of the socket 1 to form a plug-in fixation;

[0026] The plug 2 is also provided with a connected plug copper tube 22 and a docking frame 3. The plug copper tube 22 is coaxially arranged with the plug 2, and the plug copper tube 22 and the docking frame 3 are vertically arranged in a T-shaped structure. A pair of sliding clamps are provided in the docking frame 3. The sliding clamps slide along the radial direction of the plug copper tube 22 and clamp the core of the extension line to form a clamp in the plug copper tube 22.

[0027] The socket 1 is also provided with a wedge block 12. When the socket 1 and the plug 2 are plugged in, the wedge blocks 12 are located at the edge positions on both sides of the docking frame 3. The wedge blocks 12 squeeze and push the sliding clamping parts to slide relatively and hold the wire core. It can be understood that the wire core is fixed and clamped when the socket 1 and the plug 2 are connected, eliminating the need for crimping with tools and simplifying the installation steps.

[0028] In this embodiment, the sliding clamping member includes a slider 4, a protrusion 41, and an arc-shaped member 42. The protrusion 41 is installed on the upper and lower sides of the slider 4, and the arc-shaped member 42 is located on the side of the slider 4. The other side of the slider 4 is wedge-shaped and corresponds to the cross-section of the wedge block 12. The upper and lower inner walls of the docking frame 3 are provided with sliding grooves 31. The protrusion 41 slides along the sliding groove 31 to give the slider 4 a guiding direction. The arc-shaped member 42 is used to clamp the wire core.

[0029] In this embodiment, recessed grooves 32 are provided on both side edges of the docking frame 3 along the direction of the plug 2. When the wedge block 12 is inserted into the docking frame 3, a margin for insertion of the wedge block 12 is provided, thereby increasing the sliding travel of the sliding clamp in the docking frame 3.
