Description

Technical Field

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

[0002] At present, the outdoor power connectors used in outdoor base stations require high current power input and output, so the product structure of this type of outdoor power connector is complex, the volume is large, and the production process is complex. In addition, when the wiring components of the existing outdoor power connectors are installed, the wiring components are easily deformed during the injection molding process, which in turn causes dimensional changes that affect installation.

[0003] This product belongs to the outdoor power connector, which is a component used in outdoor communication base stations, with high current power input and output. This patented structure is simple, easy to install and replace, and can solve the problem of difficult outdoor operations, while also satisfying customers in terms of functionality. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a two-core outdoor power connector, so as to solve the problems that the existing connector has a complex structure and is prone to deformation during the production process.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A two-core outdoor power connector, comprising a two-core power plug, wherein the two-core power plug comprises a wiring assembly, a plug housing, and a cable sealing ring;

[0007] The wiring assembly is mounted on the front of the plug housing, and the cable sealing ring is mounted on the rear of the plug housing;

[0008] The wiring assembly comprises a cover body and a wiring frame assembly. The wiring frame assembly is installed in the cover body. The cover body comprises an extension portion and an installation portion. The extension portion is provided with reinforcing ribs.

[0009] Providing reinforcing ribs on the protruding portion of the wiring assembly can effectively prevent the plastic from shrinking and deforming during injection molding, which in turn causes dimensional changes and ultimately affects the plug-in problem. Secondly, it can also increase the structural strength of the plastic.

[0010] A further technical solution is that reinforcing ribs are provided on both sides of the extension of the wiring assembly;

[0011] The number of reinforcing ribs is 4.

[0012] A further technical solution is that an elastic buckle is arranged on the upper part of the cover body, and a fixing buckle is arranged at a position corresponding to the elastic buckle on the plug shell.

[0013] The wiring assembly adopts an elastic buckle structure. When the wiring assembly is installed in the plug shell, the buckle cooperates with the corresponding position of the plug shell; it prevents the wiring assembly from falling off and being damaged when not connected, and can also effectively ensure that the wiring assembly and the plug shell are relatively fixed after wiring; the wiring assembly can be removed by pressing the buckle. The structure is simple and easy to operate.

[0014] A further technical solution is that the two-core power plug includes a nut and a plug assembly;

[0015] The nut is installed on the outer side of the rear part of the plug shell, and the plug assembly is detachably installed in the rear part of the plug shell.

[0016] The plug assembly is used to cover and seal the front end of the nut when the wire is not connected.

[0017] A further technical solution is that the plug assembly includes a plug and a plug pull strap;

[0018] The plug is connected to a plug drawstring, and the plug drawstring is installed between the nut and the plug housing.

[0019] A further technical solution is that the two-core outdoor power connector further includes a two-core power socket;

[0020] The two-core power socket comprises a socket terminal, a front sealing ring, a metal shell, a socket base, a rear sealing ring, and a wrench;

[0021] The socket terminal is installed in the socket base, and the socket base and the wrench are installed on the metal shell;

[0022] The socket base is provided with a mounting groove matching the extension portion and the reinforcing rib;

[0023] The front sealing ring is installed at the front part of the metal shell; the rear sealing ring is installed between the metal shell and the socket base.

[0024] A further technical solution is that an external buckle is provided on the socket base;

[0025] The metal shell is provided with a buckle which cooperates with the outer buckle.

[0026] This assembly form can be effectively fixed by matching the external clips on the plastic base of the socket with the metal shell of the socket.

[0027] A further technical solution is that an inner buckle is provided on the socket base;

[0028] The socket terminal is provided with a boss for inner snap fit.

[0029] The boss on the terminal is fixed with a clip inside the plastic base of the socket; after being fixed with the clip, compared with existing similar products, two plastic clamping parts are saved and the cost is reduced.

[0030] At the same time, the snap-on structure of the socket base and the terminal assembly is a detachable structure, and the terminal can be disassembled by pressing the snap-on outward, which facilitates subsequent maintenance and saves later maintenance costs.

[0031] A further technical solution is that the wrench is provided with a mounting hole, and the wrench is mounted on the connecting shaft on the metal shell through the mounting hole, and the wrench can rotate relative to the metal shell;

[0032] The metal shell has a wrench buckling stop structure.

[0033] On the one hand, the mounting hole at the connection between the wrench and the metal is made through a stretching process, so that the inside has rounded corners and the mating surface is smooth; when mating with the connecting shaft of the metal shell, this structure can effectively ensure that the wrench and the metal shell move smoothly and reliably relative to each other, and also avoids the existing product using a sleeve connection method, saving two sleeve parts and reducing costs.

[0034] On the other hand, the metal housing has a wrench-engaging stop structure, which also has an anti-fool effect during assembly, preventing deformation and damage caused by overpressure on the wrench when it is not engaged, and can also make installation more convenient.

[0035] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model can effectively prevent the shrinkage and deformation of plastic during injection molding, which in turn causes the size change and ultimately affects the plug-in problem, by providing reinforcing ribs on the extension of the wiring assembly. At the same time, the wiring assembly adopts an elastic buckle structure, and the wiring assembly will fall off and be damaged when not connected. The structure is simple and easy to operate. The assembly is fixed by the outer buckle on the plastic base of the socket and the metal shell of the socket, and the boss on the terminal is fixed by the inner buckle of the plastic base of the socket. After being fixed by the buckle, compared with existing similar products, two plastic clamping parts are saved and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
