Description

Technical Field

[0001] This utility model relates to the field of serial connectors, and more particularly to a unidirectional data transmission serial connector. Background Technology

[0002] A data transmission serial connector is a commonly used communication interface between electronic devices. A unidirectional communication serial connector is a communication method in which data can only be transmitted in one direction. This means that one party can only send data and cannot receive data, while the other party can only receive data and cannot send data. This can be used in some special fields to ensure data security.

[0003] Traditional unidirectional data transmission connectors use only a simple connection method, which makes them prone to detachment when accidentally pulled, leading to data transmission failures. Furthermore, traditional unidirectional data transmission connectors do not have dustproof features and are easily covered in dust when not in use, which can affect the use of the connector. Therefore, a new solution is needed to address this problem.

[0004] Therefore, those skilled in the art have provided a unidirectional data transmission header to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a unidirectional data transmission serial connector. Compared to traditional unidirectional data transmission serial connectors, this connector features a limiting mechanism. When the male and female serial ports are plugged in, the male serial port continuously presses against the clamping component during insertion. The limiting spring retracts, causing the clamping component to move and hold the male serial port in place, preventing it from falling off. A dustproof mechanism is also included. A dustproof plate protects the connector from dust when not in use. When the male and female connectors are plugged in, the dustproof plate is flipped via a hinge, and then moved by a slider and a slide rail to ensure it does not obstruct the plug insertion, thus achieving dust protection for the connector.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A unidirectional data transmission connector includes a male plug and a female plug. The male plug includes a housing and a bushing. A return spring is fixedly connected to the upper and lower ends of the inner wall of one side of the housing. The female plug includes a second housing. A fixing plate is fixedly connected to the lower end of the inner wall of one side of the second housing. A limit mechanism is fixedly connected to the front and rear ends of the upper surface of the fixing plate. The limit mechanism includes multiple limit posts. A clamping member is rotatably connected to the upper and lower ends of each limit post. A clamping member is fixedly connected to the upper and lower ends of the inner walls of the front and rear ends of the second housing. Limit spring;

[0008] The lower surfaces of both the male and female plugs are fixedly connected to a dustproof mechanism, which includes multiple dustproof plates. The outer rear wall of each dustproof plate is fixedly connected to a hinge. The lower surfaces of both the bushing and the outer shell are fixedly connected to a slide rail, and the outer wall of the slide rail is slidably connected to a slider.

[0009] Through the above technical solution, the unidirectional data transmission connector is equipped with a dustproof mechanism for dust prevention, and a limit mechanism is set to limit the insertion of the male and female connectors, thereby improving the stability of the insertion.

[0010] Furthermore, a male serial port is fixedly connected to the middle of one side inner wall of the outer casing;

[0011] The above technical solution establishes a public serial port for connecting with other devices, enabling the transmission and control of electrical signals.

[0012] Furthermore, the end of the limiting spring away from the inner wall of the outer casing is fixedly connected to the clamping member;

[0013] The above technical solution uses a limit spring to drive the clamping component, which helps the clamping component to better clamp the male serial port.

[0014] Furthermore, a sealing washer is fixedly connected to the end of the bushing away from the return spring;

[0015] The above technical solution compresses the sealing gasket during the connection of the male and female plugs, preventing collisions between them and increasing the friction between the plugs to improve their stability.

[0016] Furthermore, a slide rail is fixedly connected to the lower end of the public serial port, and a slide groove is provided in the middle of the upper surface of the fixed plate;

[0017] The above technical solution, by setting up slide rail and slide groove, can guide the male and female plugs to be inserted, thereby improving the reliability and stability of the connection.

[0018] Furthermore, a female serial port is fixedly connected to the upper end of the inner wall of one side of the second outer casing;

[0019] The above technical solution involves setting up a female serial port to connect to the serial connector, thereby completing the transmission of electrical signals.

[0020] Furthermore, the end of the return spring away from the outer casing is fixedly connected to the bushing;

[0021] The above technical solution provides protection for the male serial port by setting a bushing. At the same time, when the male and female serial connectors are plugged in, the bushing retracts through a return spring to avoid obstructing the plug insertion.

[0022] Furthermore, a hinge is fixedly connected to the lower surface of the slider;

[0023] By fixing the hinge and the slider, the dustproof plate can be moved more easily.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a unidirectional data transmission connector. Compared with existing unidirectional data transmission connectors, this unidirectional data transmission connector uses a limiting mechanism and a sealing gasket on one side of the outer wall of the bushing. When the male and female serial ports are plugged in, the male serial port continuously squeezes the clamping component during the plugging process. The limiting spring retracts and drives the clamping component to move, clamping the male serial port and preventing it from falling off. At the same time, the male and female serial ports squeeze the sealing gasket, increasing the friction between the plugs and improving the stability of the plug.

[0026] 2. The present invention proposes a unidirectional data transmission serial connector. Compared with most existing unidirectional data transmission serial connectors, this unidirectional data transmission serial connector has a dustproof mechanism. A dustproof plate is set up to prevent dust when the serial port is not in use. When the male and female plugs are plugged in, the dustproof plate is flipped by a hinge, and then the dustproof plate is moved by a slider and a slide rail to ensure that it does not obstruct the plug insertion, thereby completing the dustproof function of the serial connector.

[0039] The unidirectional data transmission connector is equipped with a dustproof mechanism 3 for dust prevention, and a limit mechanism 4 is also provided to limit the insertion of the male and female connectors, thereby improving the stability of the insertion.

[0040] A male serial port 104 is fixedly connected to the middle of the inner wall of one side of the outer casing 101. The male serial port 104 is used as an interface for connecting with other devices for transmitting and controlling electrical signals. A limit spring 403, at its end away from the inner wall of the outer casing 201, is fixedly connected to a clamping member 402. The limit spring 403 drives the clamping member 402, facilitating better clamping of the male serial port 104. A sealing washer 106 is fixedly connected to the end of the bushing 102 away from the return spring 103. When the male and female plugs are connected, the sealing washer 106 is compressed to prevent collisions between the plugs and to enhance the friction between them, improving the stability of the plugs. A slide rail 105 and a fixing plate 203 are fixedly connected to the lower end of the male serial port 104. A groove 204 is provided in the middle of the upper surface. By setting the slide rail 105 and the groove 204, the male and female plugs can be guided to be inserted, improving the reliability and stability of the connection.
