Description

Technical Field

[0001] This utility model relates to the field of lifting fixtures, and in particular to a simple printed circuit board lifting fixture. Background Technology

[0002] Interconnection between modules in a terminal unit or chassis requires each individual module to be connected to an integrated printed circuit board (PCB). The connection between each module and the PCB is achieved using a bus socket. However, with the rapid development of computer bus technology and the widespread application of large-scale integrated circuits, the number of interconnected modules has gradually increased, and the number of pins on the bus socket has also gradually increased. This has increased the insertion and removal force required for the PCB socket, making it difficult to remove the PCB during testing or maintenance.

[0003] The existing technology involves prying open the printed circuit board from all sides with a wrench, which has the following drawbacks: 1. However, it is suitable for integrated printed circuit boards with a small number of interconnected modules, few bus pins, and low insertion / removal force; 2. Furthermore, uneven stress can easily cause deformation and damage to the printed circuit board; 3. The inability to control the pull-out stroke, and blindly pulling out without fully engaging the pull-out stroke, will damage the connector; 4. Inflexible operation and implementation. Utility Model Content

[0004] The purpose of this utility model is to address the problem of difficult printing board removal in the prior art by proposing a simple printing board removal tool.

[0005] A simple printed circuit board (PCB) lifting fixture includes a PCB adapter bracket, a fixed bracket, several positioning pins, and a lifting handwheel. The plurality of positioning pins are mounted on the fixed bracket; The fixed bracket is connected to the printed circuit board adapter bracket via a pull-out handwheel.

[0006] Among them, the positioning pins are used to fasten the screws of the bracket to ensure accurate positioning; The lifting handwheel transmits torque, enabling power transmission and conversion.

[0007] Furthermore, a simple printed circuit board lifting tool is provided, wherein the fixed bracket is disposed on the upper end of the printed circuit board adapter bracket.

[0008] Furthermore, a simple printed circuit board (PCB) lifting tool is provided, wherein the PCB adapter bracket is fixed to the PCB structural component by screws.

[0009] Furthermore, a simple printed circuit board lifting tool is provided, wherein the fixing bracket is guided into the pin hole of the printed circuit board adapter bracket by a positioning pin.

[0010] The pin hole provides a precise positioning and connection point, enabling the mounting bracket or printed circuit board adapter bracket to be securely joined together.

[0011] Furthermore, a simple printed circuit board (PCB) pulling tool is provided, wherein the fixed bracket and the PCB adapter bracket are connected by inserting a pulling handwheel through a threaded hole.

[0012] The beneficial effects of this utility model are as follows: It realizes the pulling of integrated printed circuit boards with a large number of interconnected modules, many bus pins, and large insertion and extraction forces by using a simple printed circuit board pulling tool; it has a wide force-bearing area, and the position of the pulling thread hole of the tool can be adjusted according to the opening position of the printed circuit board to make it evenly stressed; the pulling stroke can be adjusted by controlling the thread depth of the machining; the pulling can be achieved by simply turning the pulling handwheel, and the operation is simple and flexible.

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] As attached Figure 1 As shown, a simple printed circuit board lifting tool has the following structure: Includes a printed circuit board adapter bracket 1, a fixed bracket 2, several positioning pins 3, and a lifting handwheel 4; Several positioning pins 3 are set on the fixed bracket 2; The fixed bracket 2 is connected to the printed circuit board adapter bracket 1 by inserting the pull-out handwheel 4 into the threaded hole.

[0017] The fixed bracket 2 is set on the upper end of the printed circuit board adapter bracket 1.

[0018] The printed circuit board adapter bracket 1 is fixed to the structural component of the printed circuit board by screws.

[0019] The fixed bracket 2 is inserted into the pin hole of the printed circuit board adapter bracket 1 by the positioning pin 3.

[0020] The fixed bracket 2 and the printed circuit board adapter bracket 1 are connected by inserting the pull-out handwheel 4 through the threaded hole.

[0021] The principle of pulling out is as follows: Fix the fixed bracket 2 to the threaded hole or other mounting hole of the corresponding lifting ring of the end machine, and finally insert the lifting handwheel 4. Screw in the lifting handwheel, and the lifting force is generated by the thread, so that the printed circuit board adapter bracket 1 is subjected to an upward force, thereby realizing the lifting of the printed circuit board.
