Description

Technical Field

[0001] The utility model relates to the field of electronic components, in particular to a combined small modular serial port card. Background Art

[0002] A combined small modular serial port card is an external device that integrates multiple serial port modules and adopts a modular design. It is designed to provide serial port communication functions for computers or embedded systems. The combined small modular serial port card has the characteristics of high flexibility, excellent performance, and easy installation and configuration. It is a convenient and effective external expansion device for realizing serial port communication functions. It can make it easy for computers to expand serial or parallel ports, so it is also called a serial and parallel port expansion card.

[0003] However, most of the combined small modular serial port cards currently have the following problems:

[0004] For example, a combined bus serial port card with publication number CN217641908U can limit the connection line by installing a limit plate, but the connection lines are of different sizes and thicknesses, and the installed limit plate cannot limit the connection according to the size of the connection line, affecting the stability of the connection line. At the same time, the equipment can be protected by the cooperation of the base and the upper cover, but the protection is mostly connected and fixed by bolts, etc. When the protected equipment needs to be inspected and maintained, multiple bolts need to be removed, which is troublesome and inconvenient for convenient disassembly and installation of the equipment.

[0005] Therefore, we make improvements to this problem and propose a combined small modular serial port card. Utility Model Content

[0006] The purpose of the utility model is to solve the existing problems that the position cannot be limited according to the size of the connecting line and the equipment is not convenient to be disassembled and installed.

[0017] In the scheme of this application:

[0018] 1. By setting the clamping plate, when limiting the connection line, the upper cover plate and the lower cover plate can be closed, and the placed connection line can be clamped at the same time. If the connection line is thicker, the guide rod can be pushed inward by the clamping plate, and the guide rod can support the clamping plate to move smoothly. The clamping plate can squeeze the first spring when moving. When the connection line is thinner, the clamping plate can be pushed to move by the first spring.

At the same time, the limit plates can drive the first card block to separate from the upper cover and the lower cover and retract them into the installation box. The limit plates can squeeze the second spring. When the installation box is unobstructed, the installation box and the second card block can be separated from the upper cover and the lower cover, and the upper cover and the lower cover can be disassembled and opened for easy inspection and maintenance.
