Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of multilayer circuit boards, in particular to a combined multilayer circuit board. Background Art
[0002] Circuit boards are classified into three categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards. The manufacturing method of multi-layer circuit boards generally involves first making the inner layer graphics, then using the printing and etching method to make single-sided or double-sided substrates, and incorporating them into the designated interlayers, and then heating, pressurizing, and welding them. Existing multi-layer circuit boards need to be heated, pressurized, and bonded. When the multi-layer circuit board is accidentally dropped and the internal circuit is damaged, the pressurization and bonding process makes it difficult to separate the circuit board for repair. If one layer of the circuit board is damaged, the entire multi-layer circuit board cannot be used directly. In addition, the multi-layer circuit board is positioned and assembled by welding, which requires a high level of proficiency for the operator. Because the assembly operation is relatively troublesome, the operator's work efficiency is low. For this reason, a combined multi-layer circuit board is proposed. Utility Model Content

[0011] Technical effects and advantages of the utility model:
[0012] 1. The slider can only slide in the slide groove and is fixedly connected to the splint to limit the screw sleeve to ensure that the screw sleeve moves in the direction of the slide groove. The hexagonal head can be rotated by a hexagonal wrench. The rotation of the hexagonal head drives the two-way screw to rotate. The rotation of the two-way screw drives the screw sleeve to move toward or in the opposite direction. The movement of the screw sleeve drives the splint to move. The splint moves toward each other to clamp and fix the main body of the multi-layer circuit board, reduce the contact between the main body of the multi-layer circuit board and the fixed frame, and ensure the heat dissipation performance of the main body of the multi-layer circuit board.

At the same time, the installation and disassembly operations are simple and convenient, which increases the assembly efficiency of the operator.
[0013] 2. The hinge can be toggled, and the hinge rotates and pulls the sliding rod. The movement of the sliding rod drives the movable block and the arc plate to move. The movement of the arc plate drives the second tooth to move, so that the second tooth is no longer meshed with the first tooth, that is, the closing plate can be rotated. When the sliding rod moves and drives the movable block to move, the movable block moves and compresses the reset spring, so that the reset spring is in a compressed state. When the hinge rotates, the movable block is pressed by the elastic force of the reset spring, and the movement of the movable block drives the sliding rod to move. The movement of the sliding rod drives the arc plate to move, so that the arc plate is reset, and the second tooth on the arc plate is meshed with the first tooth again, so as to realize the limit locking of the closing plate. The opening slot is opened and closed by rotating the closing plate, so that the multi-layer circuit board body is inserted into the fixed frame through the opening slot. The multi-layer circuit board body is wrapped by the fixed frame and the closing plate, which plays a certain protective role. BRIEF DESCRIPTION OF THE DRAWINGS
