Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a connector used for a communication port. Background Art
[0002] At present, the State Grid requires that the service life of smart meters and related power equipment must be more than 16 years, and all power equipment must be interconnected. In order to meet or ensure the service life of the product, the key components must be upgraded. Nowadays, new energy photovoltaic power generation is increasingly valued by various countries. The direct current generated by photovoltaic solar panels must be converted into alternating current by inverters, and then the alternating current is transmitted to the terminal equipment. In the whole process, the connection between photovoltaics and inverters, and the communication connection between inverters and terminal power equipment and control equipment become particularly important. These connection environments are completed outdoors, especially photovoltaic solar panels, which are placed on roofs or mountaintops with sufficient sunshine. They are often exposed to high temperature and high humidity. The connection lines of general structures are very likely to fail in a short time. In order to make these devices operate normally for a long time, the ability of the connection lines to resist high temperature and high humidity must be guaranteed first. In order to connect the inverter to the grid and realize remote control, each inverter must be controlled by communication. Under the existing resources, the best way is to communicate and connect between the existing smart meter network and the inverter. For this reason, the communication ports between various power equipment and the connection between the connection lines and ports become very critical. Utility Model Content
[0003] In view of the above technical problems in the related art, the utility model provides a connector for a communication port, which can solve the above problems.
[0004] In order to achieve the above technical purpose, the technical solution of the utility model is implemented as follows:
[0005] A connector for a communication port, comprising a rubber core, a terminal, and an outer film, wherein the rubber core is provided with a rubber core PIN hole, the outer side surface of the rubber core is processed with an external thread, the rubber core is provided with a sealing ring slot, an anti-fool block, a button and a buckle, a sealing ring is provided in the sealing ring slot, the terminals include long terminals and short terminals, the terminals are provided with terminal clamping points and terminal welding cups, the terminals are inserted into the rubber core PIN hole, the terminal clamping points and the rubber core PIN hole are interference fit, the terminal welding cups are welded to the wires, the outer film is provided with a wire sheath, the surface of the outer film is processed with anti-slip ribs, and the outer film wraps the rubber core and the wires inside.
[0006] Furthermore, the terminal is processed with a terminal cutting edge, and an anti-rotation groove is provided in the rubber core PIN hole, and the terminal is prevented from rotating in the rubber core PIN hole through the cooperation between the terminal cutting edge and the anti-rotation groove.
[0007] Furthermore, the outer film is manufactured by injection molding.
[0008] Furthermore, the surface of the sealing ring is designed with a plurality of convex ribs, and the plurality of convex ribs make the sealing ring fit tightly around the corresponding socket without any gap. Through the anti-foolproof block, in cooperation with the anti-foolproof groove on the corresponding socket, the connector can have a blind insertion function. Through the buckle and the button, in cooperation with the slot on the corresponding socket, the connector and the socket are engaged and not easy to fall off. When the connector needs to be unplugged, the button is pressed to separate the buckle from the slot.
[0009] Furthermore, the long terminal mainly transmits power and grounding. When the connector is plugged into a corresponding socket, the long terminal first contacts the socket, and after grounding, the short terminal contacts the corresponding socket.
[0010] The beneficial effects of the utility model: the connector of the present application wraps the entire welded wire rubber core and the wire in all directions through the outer film, and has the ability of being waterproof, dustproof and airproof after wrapping. The external thread designed on the rubber core increases the bonding force between the outer film and the rubber core under the action of the concave and convex structure of the external thread, so that the outer film will not fall off easily. At the same time, in order to improve the anti-swaying strength of the wire, the wire sheath on the outer film will absorb most of the external force when the wire swings 360 degrees, so that the wire is not easy to break. Through the design of long and short terminals, the connector is grounded first when inserted to protect the transmission signal from interference. Through the sealing ring, the entire plug-in area becomes a sealed area. Through the cooperation of the buckle and the slot, the stability of the connector during insertion is improved. Through the design of anti-fool blocks and anti-fool slots, the connector has the function of blind insertion. BRIEF DESCRIPTION OF THE DRAWINGS
