[0002] Medical devices refer to instruments, equipment, appliances, materials or other items used on the human body alone or in combination, including the required software. Medical devices are the most basic elements of medical treatment, scientific research, teaching, institutions, and clinical disciplines, including both professional medical equipment and home medical equipment. When medical devices are used, in order to ensure the transmission of electrical signals, digital signals, etc., the equipment needs to be connected through electrical connectors.

[0003] The electrical connectors of existing medical equipment usually adopt the contact form of plug-in terminals combined with clamp terminals. The common clamp terminals are usually copper round tubes. After the clamp terminals and the plug-in terminals are frequently plugged in and out, the clamp terminals are easily deformed. The waterproof sealing ring of this connection method is relatively traditional. Since the medical plug connector needs to be disinfected, cleaned and maintained frequently, the possibility of loosening and damage of the waterproof sealing ring may increase during this process, which makes the connector unstable during use and the waterproof performance degraded. For this reason, we propose a waterproof and corrosion-resistant medical plug connector to solve the above problems. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-4The utility model embodiment is a waterproof and corrosion-resistant medical plug connector, which includes: a connector 1 and a connector 2, which are used for medical plugs and medical equipment. The outer surface of the connector 1 is fixedly connected with a connecting clip 101 for fixing a spring sheet 103. The side of the connecting clip 101 is fixedly connected with the spring sheet 103. The spring sheet 103 is U-shaped, which is convenient for the spring sheet 103 to be fixed through a card slot 201. One end of the connector 1 is fixedly connected with a plug shell 102 for protecting the connecting end of the plug. The inside of the connector 1 is fixedly connected with a sealing tube 104. The inside of the sealing tube 104 is provided with a sealing groove 105 for fitting with the sealing ring 202 to form a closed component. The inside of the plug shell 102 is fixedly connected with a cable. The outer surface of the cable is fixedly connected through the connector 1, which is convenient for protecting the cable inside the plug shell 102. The inside of the connecting clip 101 is provided with a limiting groove 106. The inside of the limiting groove 106 is provided with a pressing block, and the side of the pressing block is fixedly connected with one end of the spring sheet 103. Used to fix connector 1 and connector 2, the outer diameter of the spring sheet 103 is consistent with the inner diameter of the slot 201, and one end of the spring sheet 103 connected to the pressing block is not connected to the side of the connecting clip 101, so that the upper part of the spring sheet 103 is clamped and fixed in the slot 201, and the inner bottom surface of the connector 2 2 and the inner surface of the isolation ring 203 are provided with a docking groove 204, and the surface of the docking groove 204 is provided with anti-rust paint, which is convenient for connection with the sealing tube 104.

[0025] A card slot 201 is provided inside the connector 2 for connection with the spring sheet 103. An isolation ring 203 is fixedly connected inside the connector 2 for fixing the sealing ring 202. The outer surface of the isolation ring 203 is fixedly connected with the sealing ring 202. The sealing ring 202 is wavy and is used to enhance the waterproofness of the connector. The sealing ring 202 and the inner surface of the connector 2 form a connecting groove 205 for sealing the box to fix the sealing tube 104. A gasket is fixedly connected to the end of the sealing tube 104 away from the plug housing 102. When the sealing tube 104 is connected to the connector 2, it is connected to the inside of the connecting groove 205 through the gasket to protect the inner wall of the connecting groove 205 and achieve a secondary sealing effect. Two connecting clips 101 and the card slot 201 are symmetrically arranged respectively to enhance the stability of the connector 1 and the connector 2 after connection.

[0026] Working principle: When using the waterproof and corrosion-resistant medical plug connector, first connect the connector 2 to the medical device through screws, and then connect the connector 1 to the slot 201 through the connecting clip 101, press the pressing block connected to the upper surface of the spring sheet 103, and push the spring sheet 103. After the spring sheet 103 enters the slot 201, the end of the spring sheet 103 that is not connected to the connecting clip 101 pops up and conflicts with the inner top wall of the slot 201, assisting the sealing effect of the sealing tube 104 and the sealing ring 202. At the same time, the sealing tube 104 is inserted into the connecting groove 205 and fits with the sealing ring 202, and the isolation ring 203 is inserted into the sealing groove 105 and fits with it. One end of the sealing tube 104 connected to the gasket fits with the docking groove 204. After the connection is completed, the pressing block in the limiting groove 106 protrudes higher than the surface of the connecting clip 101, which is convenient for pressing the spring sheet 103 by the pressing block.
