Technical field

A multi-layer PCB circuit board fixing fixture

The utility model relates to the technical field of a fixing jig for a PCB circuit board, in particular to a fixing jig for a multilayer pcb circuit board.

Background technique

The PCB circuit board, also known as the printed circuit board, is a provider of electrical connections for electronic components. The main advantage of using it is that it greatly reduces wiring and assembly errors, and improves the automation level and production labor rate. In the actual production of circuit boards, often need a Clamp and fix the PCB circuit board to check the connection and conductivity of each electrical circuit. The existing pcb circuit board itself has positioning holes for connection and fixing. When fixing the circuit board, the PCB circuit board itself can be relied on Perform fixed clamping.

However, when the existing devices fix circuit boards, most of them can only be fixed by a single circuit board. When fixing and clamping multi-layer circuit boards, the clamping is not stable enough, and the superimposed circuit boards are not neat up and down. In view of this, we have a multi-layer pcb circuit board fixing fixture provided to solve the above problems.

Technical solutions

In order to achieve the above object, the utility model provides the following technical solution: a multi-layer pcb circuit board fixing fixture, including a base, the center of both ends of the base is fixedly connected with a baffle, and the center of one side of the baffle is movable A rotating rod is connected, a chute is opened on the upper surface of the base, and a slider is movably connected inside the chute, a groove is opened on one side of the upper surface of the slider, and a support column is fixedly connected to the top of the slider. The outer wall of the support column is movably sleeved with clamping blocks, both ends of the clamping block are fixedly connected with a pressure plate, and one end of the pressure plate is movably connected with an insertion rod, one side of the clamping block is fixedly connected with several protrusions, and one side of the protrusions A circuit board is provided, and several positioning holes are opened on the upper surface of the circuit board, and several connecting grooves are opened on both sides of the circuit board.

The baffle is fixedly connected to both ends of the chute, and a threaded hole is opened in the center of one side of the baffle, and the outer wall of the rotating rod is provided with threads, and one end of the rotating rod passes through the threaded hole and is movably connected with the slider.

The slider is slidably connected to both ends of the chute, and a circuit board is placed on the top of one end of the slider. The top of the slider is movably connected to the clamping block through a support column, and the support column is cylindrical as a whole.

The support column is movably interspersed at both ends of the clamping block, and the tops of both ends of the clamping block are fixedly connected to a pressure plate, and a small hole is opened on the upper surface of one end of the pressure plate, and the bottom end of the pressure plate is close to the circuit board.

One side of the clamp block is provided with a rubber pad, and the other side of the rubber pad is close to the circuit board. The small hole at one end of the pressure plate is at the same level as the positioning hole, and the bottom end of the insertion rod is respectively inserted into the small hole and the positioning hole.

Both sides of the circuit board are provided with a set of relative sliding blocks and clamping blocks, and one side of the clamping blocks is connected to the inside of the connecting groove through a protrusion.

Beneficial effect:

Compared with the prior art, this multi-layer PCB circuit board fixing fixture has the following beneficial effects:

The utility model rotates the rotating rod so that one end of the rotating rod pushes the slider, and the slider slides along the chute to the center of the chute, and the slider drives the clamping block, thereby clamping and fixing the placed circuit board left and right, using the slider The connection relationship with the clamping block enables the clamping block to move up and down on the top of the slider, which is convenient for the device to clamp and fix the multilayer circuit board.

The utility model drives the clamping block to slide through the sliding of the slider, so that one side of the clamping block is close to the circuit board, and a rubber pad is provided on one side of the clamping block so that when the clamping block contacts the circuit board, the clamping force can be relieved to prevent The two sides of the circuit board are damaged. By sliding the clamp up and down, it is convenient to place multiple superimposed circuit boards. Use the pressure plate to press the circuit board at the top, and then connect the bottom end of the insertion rod through the pressure plate to the inside of the positioning hole, so that the device can Realize the fixed clamping of multi-layer circuit boards or single-layer circuit boards, and ensure that the multi-layer circuit boards are neatly clamped.

Other advantages, objectives, and features of the present utility model will be set forth in the following description to some extent, and to some extent, based on the investigation and research below, it will be obvious to those skilled in the art or can be Get teaching from the practice of the utility model.
