Circuit board fixing device

Abstract

The invention discloses a circuit board fixing device, and the device comprises a device bottom plate. The outer wall of the top of the device bottom plate is provided with four fixing device bodies,and the four fixing device bodies are respectively located at four corners of the device bottom plate. Each fixing device body comprises an adjustment stud, and the outer wall of the top of the devicebottom plate is provided with a sliding groove. Moreover, the profile structure of the sliding groove is concave, and the inner wall of the bottom of the sliding groove is provided with a row of adjustment grooves which are arranged at equal intervals. The adjustment studs are plugged in the adjustment grooves, and the outer walls of the studs are sleeved by a sliding plate which is located in the sliding groove. The outer wall of the top of the sliding plate is welded with a transmission column. The device is compact in structure, is practical and novel, can achieve the stable fixing effectfor the application, conveying and maintenance of a circuit board, brings convenience to a worker for operation and use, is suitable for the fixing of many types of circuit boards, and improves the convenience and practicality.

Description

technical field [0001] The invention relates to the technical field of fixing devices, in particular to a circuit board fixing device. Background technique [0002] Circuit boards, also known as circuit boards, make circuits miniaturized and intuitive, and play an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. According to the number of layers, circuit boards are divided into three major categories: single-panel, double-panel, and multi-layer circuit boards. The circuit board is mainly composed of pads, via holes, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. There are through holes at the four corners of the circuit board to fix the circuit board. At present, Most of the fixing devices for circuit boards are simple in structure, and are only suitable for the use of circuit boards, not for circuit board maintenance, and have relatively large limitations. Therefore, there is an urg...

Problems solved by technology

The circuit board is mainly composed of pads, via holes, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. There are through holes at the four corners of the circuit board to fix the circuit board. At present, Most of the fixing devices for circuit boards are simple in structure, and are only suitable for the use of circuit boards, not for circuit board maintenance, and have relatively large limitations. Therefore, there is an urgent need for a circuit board fixing device suitable for various occasions. device to make up for this deficiency
