Description

Technical Field

[0001] The utility model relates to the technical field of outdoor power connectors, and more specifically, to a three-core outdoor power connector. Background Art

[0002] At present, the three-core outdoor power connector used in outdoor base stations needs to meet the requirements of safety protection and the input and output requirements of high current power supply. Therefore, the product structure of this type of outdoor power connector is complex and the volume is large. Moreover, its complex structure leads to complex production process, especially between the socket base and the socket shell. In the prior art, two plastic positioning parts are required, and it is easy to cause interference during the assembly process, resulting in scratches and damage. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a three-core outdoor power connector, so as to solve the problems of the prior art having a relatively complex structure and being difficult to install.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A three-core outdoor power connector, comprising a three-core AC socket, wherein the three-core AC socket comprises a socket back cover, a socket terminal, a socket base, a socket shell, and a socket wrench;

[0006] A limiting ring is arranged in the middle of the socket base, the socket rear cover is sleeved on the front half of the socket base, and matching buckles are arranged on the socket rear cover and the front half of the socket base, and are fixed by the buckle limit;

[0007] A limiting ring is arranged in the middle of the socket shell, and the socket shell is sleeved on the rear half of the socket base. Matching buckles are arranged on the socket shell and the rear half of the socket base, and the buckles are used to limit and fix.

[0008] The socket wrench can be rotatably mounted on the socket housing;

[0009] There are three socket terminals, which are fixedly arranged between the socket rear cover and the socket base.

[0010] Since a limiting ring is arranged in the middle of the socket base, during installation, it is only necessary to install the socket back cover, the socket shell and the socket base, and the mutually cooperating buckles can complete the connection and fixation between the socket back cover, the socket shell and the socket base. When connected and fixed, the socket back cover and the socket base jointly support and fix the socket terminal, and the installation is completed.

[0011] A further technical solution is that the three-core AC socket further includes a sealing ring A, and the sealing ring A is arranged between the socket base and the socket shell.

[0012] A further technical solution is that the three-core AC socket further includes a sealing ring B, and the sealing ring B is arranged inside the socket shell.

[0013] The sealing ring prevents water from entering and protects the connection safety.

[0014] A further technical solution is that a protrusion is provided at the rear of the socket base, and a matching slot is provided at a corresponding position of the socket shell;

[0015] The rear part of the socket base is provided with a protrusion which adopts a reduced glue design.

[0016] The reduced-glue design means that the diameter of the socket base at the protrusion is smaller than that at other positions. The reason for adopting this design is to prevent the protrusion between the socket shell and the socket base from being squeezed during the installation process, which ultimately leads to failure of the protrusion or deformation of the socket shell.

[0017] A further technical solution is that reinforcing ribs are arranged on the outside of the socket shell.

[0018] Adding reinforcing ribs can further improve the strength and deformation resistance of the socket shell, and can reduce the deformation of the socket shell in high and low temperature environments, thereby avoiding the failure of the product's waterproof function.

[0019] A further technical solution is that the socket terminal includes a socket L terminal, a socket N terminal, and a socket PE terminal;

[0020] The socket L terminal, the socket N terminal and the socket PE terminal are fixed between the socket rear cover and the socket base.

[0021] A further technical solution is that the socket back cover and the socket base are made of plastic.

[0022] The socket back cover and the socket base are made of plastic material, which can make the socket back cover and the socket base have a certain degree of elasticity and facilitate installation.

[0023] A further technical solution is that the three-core outdoor power connector also includes a three-core AC plug;

[0024] The three-core AC plug includes a wiring assembly, a plug housing, a cable sealing ring, a plastic nut, and a plug assembly;

[0025] The wiring assembly is installed at the front section inside the plug shell, the plastic nut is fixed at the rear section outside the plug shell, the cable sealing ring is installed between the plug shell and the plastic nut, and the plug assembly is installed at the rear of the plug shell.

[0026] A further technical solution is that the plug assembly includes a plug and a pull strap;

[0027] The drawstring is connected to the plug and is sleeved on the plug housing.

[0028] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model sets a limiting ring in the middle of the socket base. When installing, it is only necessary to install the socket back cover, the socket shell and the socket base, and the mutually matched buckles can complete the connection and fixation between the socket back cover, the socket shell and the socket base, reducing two plastic clamping parts while reducing the installation difficulty and cost. At the same time, the applicability of the power connector is improved by reducing the glue design and adding reinforcing ribs. BRIEF DESCRIPTION OF THE DRAWINGS
