Description

Technical field

[0001] The utility model belongs to the technical field of PCB boards, and in particular relates to a fixing support device for testing PCB boards. [Background Technology]

[0002] PCB board, whose Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection between electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use printed circuit boards to make electrical interconnections between various components.

[0003] After production, PCBs undergo an inspection process to ensure that each PCB is functioning properly. This requires a fixture to secure the PCBs. Existing fixtures secure the tail end of the PCBs. However, due to the length of the PCBs, prolonged fixture testing can cause the tail end to fall and deform, impacting test results and accuracy. Furthermore, existing fixtures can only secure the PCBs at a certain height, limiting their versatility. [Utility Model Content]

[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for the purpose of distinction.

[0041] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0042] Specific embodiments, such as Figure 1-3 The illustrated fixed support device for testing PCB boards comprises: a placement base 1; a fixing mechanism 2, disposed on the placement base 1, for fixing the rear end of the PCB board; a support member 3, disposed on the placement base 1, for supporting one end of the PCB board away from the fixing mechanism 2; a first height adjustment mechanism 4, disposed between the fixing mechanism 2 and the placement base 1, for adjusting the height of the fixing mechanism 2; and a second height adjustment mechanism 5, disposed between the support member 3 and the placement base 1, for adjusting the height of the support member 3. During use, the rear end of the PCB board is fixed to the fixing mechanism, and the height of the support member is adjusted via the second height adjustment mechanism to support the front end of the PCB board, preventing the PCB board from falling and deforming over time, thereby ensuring test results and accuracy. Furthermore, the height of the fixing mechanism, i.e., the height position of the PCB board, can be adjusted via the first height adjustment mechanism according to the actual test environment, resulting in greater versatility and flexibility.

[0043] Specifically, the fixing mechanism 2 includes a fixing base 21 for supporting the PCB; a U-shaped stopper 22 with both ends disposed on the fixing base 21. A stopper channel 6 is formed between the U-shaped stopper 22 and the fixing base 21, through which the PCB passes. The U-shaped stopper 22 is provided with at least two fixing holes 7 arranged along its length; and a fixing bolt 23, one end of which passes through the fixing holes 7 and extends into the stopper channel 6 to secure the PCB passing through the stopper channel 6. During installation, the PCB passes directly through the stopper channel 6, where it is held in place by the U-shaped stopper 22. The fixing bolt 23 then engages the fixing holes 7 to secure the PCB, making installation convenient.

[0044] In addition, the fixing base 21 and the support member 3 are made of silicone or plastic. The PCB board needs to be tested with electricity, and it is safer to use insulating materials. Silicone or plastic materials have good elasticity and shock resistance, effectively protecting the PCB board. At the same time, silicone materials are aging-resistant and wear-resistant, and have a longer service life.

[0045] Furthermore, there are multiple U-shaped limiting members 22, and the multiple U-shaped limiting members 22 are arranged along the direction in which the PCB board passes through the limiting channel 6, so that the fixation is more stable.

[0046] More specifically, the first height adjustment mechanism 4 includes: a first connecting member 41, which includes a first horizontal panel 411 connected to the placing base 1, and a first vertical panel 412 connected to the first horizontal panel 411; a second connecting member 42, which includes a second vertical panel 421 arranged opposite to the first vertical panel 412, a second horizontal panel 422 connected to the second vertical panel 421, and a third vertical panel 423 connected to the second horizontal panel 422 at an end away from the second vertical panel 421, and the third vertical panel 423 is connected to the fixing seat 21 at an end away from the second horizontal panel 422; a first waist-shaped hole 43, which is arranged on the first vertical panel 412 in the vertical direction; a first height adjustment hole 44, which is arranged on the second vertical panel 421 and corresponds to the first waist-shaped hole 43; a first height adjustment bolt 45, which is passed through the first waist-shaped hole 43 and the first height adjustment hole 44, for fixing the first connecting member 41 and the second connecting member 42. By adjusting the height positions of the first connecting member 41 and the second connecting member 42 while ensuring that the first height adjustment hole 44 is opposite to the first waist-shaped hole 43, after the adjustment is completed, the first height adjustment bolt 45 is used to lock and fix it, which makes the adjustment convenient and the use more flexible.

[0047] Furthermore, a first sliding limit groove 14 is provided on one side of the first vertical panel 412 opposite to the second vertical panel 421, and the second vertical panel 421 can be movably embedded in the first sliding limit groove 14 in the vertical direction, making installation and adjustment more convenient.

[0048] Furthermore, a second horizontally arranged sliding limit slot 8 is provided on the side of the fixing base 21 close to the third vertical panel 423, and a fixing base mounting hole 9 is provided on the side of the fixing base 21 away from the third vertical panel 423. The fixing base mounting hole 9 is connected to the second sliding limit slot 8. The third vertical panel 423 is embedded in the second sliding limit slot 8 so as to be movable left and right in the horizontal direction. Bolts are sequentially inserted through the fixing base mounting hole 9 and the second sliding limit slot 8 to restrict the left and right movement of the fixing base 21 relative to the third vertical panel 423. This enables left and right adjustment of the fixing base 21, and the adjustment is convenient, making it more flexible to use.

[0049] Specifically, a bolt receiving slot 10 is provided on a side of the fixing base 21 away from the third vertical panel 423. The bolt receiving slot 10 is connected to the fixing base mounting hole 9. When a bolt passes through the fixing base mounting hole 9 and the second sliding limit slot 8 in sequence and restricts the left and right movement of the fixing base 21 relative to the third vertical panel 423, the upper end of the bolt is received in the bolt receiving slot 10. This prevents the bolt from protruding from the surface of the fixing base 21 and damaging the PCB.

[0050] More specifically, the second height adjustment mechanism 5 includes: a third connecting member 51, which includes a third horizontal panel 511 connected to the placement base 1, and a fourth vertical panel 512 connected to the third horizontal panel 511; a second waist-shaped hole 52, which is vertically provided on the support member 3; a second height adjustment hole 53, which is provided on the fourth vertical panel 512 and corresponds to the second waist-shaped hole 52; and a second height adjustment bolt 54, which is inserted into the second waist-shaped hole 52 and the second height adjustment hole 53 and is used to fix the third connecting member 51 and the support member 3. The height of the support member 3 can be adjusted according to actual usage, making it more flexible.

[0051] Furthermore, the third horizontal panel 511 is provided with a third waist-shaped hole 11 arranged along the length of the placement base 1. The placement base 1 is provided with a front-to-back adjustment hole 12 corresponding to the third waist-shaped hole 11. Front-to-back adjustment bolts 13 are inserted through the third waist-shaped hole 11 and the front-to-back adjustment hole 12. The support member 3 can be adjusted to move closer to or away from the fixing base 21 according to the length of the PCB board, thereby adjusting the distance between the support member 3 and the fixing base 21.
