Description

Mounting seat for printed circuit board

Technical Field

The invention relates to the technical field of printed circuit boards, in particular to a mounting seat for a printed circuit board.

Background

In the fields of industrial control systems, industrial automation and the like, electronic modules of circuit boards such as relay couplers, photoelectric couplers, active and passive isolators, transmitters, switching power supplies, input and output interface devices, switches, isolator switches, fuse combined electrical appliances, control and protection switching electrical appliances and the like are increasingly used, and how the electronic modules are arranged, whether the installation is firm and reliable, whether the operation is convenient and fast, and the quality, the progress and the cost of electrical engineering are directly influenced. In view of this, chinese patent publication No. CN203596997U discloses a circuit board support based on modular design, which adopts a support main body and a cover body to cooperate, and a guide groove is arranged in the main body to clamp a circuit board, thereby avoiding the drawback of screw fixation, reducing the accident rate, and improving the reliability of the product. Although the product solves the problem that whether the electronic modules are convenient to mount and fix, the openings are formed on the two sides of the main body, and when a plurality of supports are mounted on the cabinet, effective partitions are not formed between the electronic modules in the supports, so that the creepage phenomenon is easy to generate, and the performance of the electronic modules is adversely affected. If form totally enclosed four sides clad structure with major structure, though can increase creepage distance like this, avoid creepage phenomenon, improve the security performance, nevertheless because including electronic module is totally enclosed, be unfavorable for the heat dissipation, can influence electric property equally. In addition, because there is the opening in main part both sides for the effort that major structure can bear is little, and support overall structure is firm enough, takes place to warp because of the atress easily, can not play effectual guard action to electronic module better, for this reason, we provide a mount pad for printed circuit board.
