Description

PCB fixing support

[ technical field ] A method for producing a semiconductor device

The utility model relates to a circuit board field especially relates to a PCB board fixed bolster.

[ background of the invention ]

The circuit boards are classified into three major categories, i.e., single-sided boards, double-sided boards, and multilayer circuit boards, in which the components are concentrated on one side and the wires are concentrated on the other side of the most basic circuit board. Such a circuit board is called a single-sided circuit board because the conductors are present on only one side thereof. The single-panel is generally simple to manufacture and low in cost, but has the disadvantage that the single-panel cannot be applied to a complex product, the double-panel is an extension of the single-panel, and when single-layer wiring cannot meet the requirements of an electronic product, the double-panel is used. The multilayer board is a printed board which is formed by laminating more than three conductive pattern layers and insulating materials between the conductive pattern layers at intervals, and the conductive patterns are interconnected according to requirements.

Present circuit board is a plate that is used for integrated circuit to bear, however, need detect the circuit board after the circuit board production, detect the circuit board after fixing the circuit board through fixed tool, like patent application number: CN202120215973.2 discloses a PCB fixing device convenient for PCB detection, which fixes a PCB to be detected in a placing groove, but such fixing device can only satisfy the fixing requirement of the PCB with the size corresponding to the placing groove, and cannot satisfy the fixing requirements of the PCBs with different sizes.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming above-mentioned prior art's shortcoming, providing a PCB board fixed bolster.

The utility model discloses can realize through following technical scheme:

the utility model discloses a PCB board fixed bolster contains the bottom plate, the bottom plate upper end is fixed with the backup pad, all be fixed with the locating plate on the bottom plate of backup pad both sides, one side that the backup pad was kept away from to the locating plate all is provided with the connecting rod, still be fixed with many locating levers on the connecting rod, the locating lever pass the locating plate that corresponds the position and with locating plate sliding connection, the locating lever end all is fixed with the locating piece, two still be fixed with the connecting plate on the bottom plate between the locating plate, all be fixed with the bracing piece on the connecting rod, bracing piece and connecting plate sliding connection, the bracing piece end all is fixed with the screwed pipe, still be provided with the screw rod of being connected with the connecting plate rotation on the connecting plate, the screw rod pass two screwed pipes and with screwed pipe threaded connection. When the circuit board is fixed, place the circuit board in the backup pad, rotate the screw rod, because the screw rod pass two screwed pipes and with screwed pipe threaded connection, when the screw rod rotates, two screwed pipes are close to each other, two spinal branch vaulting poles are close to each other, the bracing piece drives the connecting rod and is close to each other, the locating lever is close to each other, fix the circuit board between the locating piece of both sides after locating piece and circuit board contact, detect the circuit board after the circuit board is fixed, it is fixed with the circuit board after contacting with the circuit board after driving the locating piece to remove through the screw rod, can satisfy not unidimensional circuit board fixed demand.

Preferably, the positioning plates are respectively fixed with a positioning tube at the position corresponding to the positioning rod, and the positioning rod passes through the positioning tube at the corresponding position and is in sliding connection with the positioning tube. The positioning rod can be stably moved through the positioning tube.

Preferably, a slide rail is fixed on the connecting plate, and a slide block connected with the slide rail in a sliding manner is fixed on the supporting rod.

Compared with the prior art, the utility model has the advantages that:

the positioning block is driven by the screw to move and then is in contact with the circuit board, and then the circuit board is fixed, so that the fixing requirements of the circuit boards with different sizes can be met.
