[0001] The utility model relates to the technical field of circuit boards, in particular to a transfer flexible circuit board. Background Art
[0002] A circuit board can be called a printed circuit board or a printed circuit board, also known as a flexible circuit board. A flexible circuit board is a printed circuit board made of polyimide or polyester film as a substrate with high reliability and excellent flexibility.
[0003] The adapter circuit board can also be called a PCB adapter board. When the computer motherboard is produced, the PCI function needs to be tested, so a PCI card must be inserted into the PCI slot of the motherboard.

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0030] See also Figures 1 to 4, is a transfer flexible circuit board in an embodiment of the utility model, including a transfer board body 10 and an auxiliary fixing mechanism.
[0031] Among them: one end of the adapter board body 10 is inserted into the PCI slot of the device under test 20, and the other end thereof is connected to a test bench 30. The auxiliary fixing mechanism is located above the device under test 20. The auxiliary fixing mechanism is used to fix the adapter board body 10 in the PCI slot of the device under test 20. Specifically, the auxiliary fixing mechanism includes a slide 41, a slider 43 and a limiting structure. The slide 41 is connected to the test bench 30 through a mounting frame. The slide 41 is perpendicular to the surface of the device under test 20. The slider 43 is movably connected to the slide 41 through the limiting structure. 1 is provided with a displacement groove 42, which extends from one end of the slideway 41 to the other end thereof, so that the displacement groove 42 passes through the opposite ends of the slideway 41, and the slider 43 is inserted into the displacement groove 42, and the slider 43 slides along the displacement groove 42. When the slider 43 moves a certain distance toward the direction of the device under test 20, the height position of the slider 43 relative to the slideway 41 is limited by the limiting structure, so that the slider 43 abuts against the top of the device under test 20, thereby ensuring that the connection between the adapter board body 10 and the PCI slot is not easy to be loosened.
[0032] In this embodiment, the limiting structure is a connecting rod structure, which includes a first connecting rod 44 and a second connecting rod 45. The opposite ends of the first connecting rod 44 and the second connecting rod 45 are rotatably connected to the slide 41 and the slider 43 respectively, and the opposite ends of the first connecting rod 44 and the second connecting rod 45 are connected by a bolt structure 46. It can be understood that when the slider 43 slides relative to the slide 41 and along the displacement groove 42, the angle between the first connecting rod 44 and the second connecting rod 45 will change, and when the slider 43 slides toward the direction of the device to be tested 20, the angle between the first connecting rod 44 and the second connecting rod 45 will first decrease and then increase.
[0033] It should be noted that the first connecting rod 44 and the second connecting rod 45 are fixedly connected or movably connected by tightening or loosening the bolt structure 46. When the bolt structure 46 fixes the first connecting rod 44 relative to the second connecting rod 45, the slider 43 is also fixedly connected relative to the slideway 41.
[0034] In this embodiment, the bolt structure 46 includes matching bolts and nuts, and the bolts and nuts are threadedly connected. It can be understood that tightening the nuts can make the first connecting rod 44 and the second connecting rod 45 relatively fixed, wherein the first connecting rod 44 and the second connecting rod 45 are respectively provided with a first through hole and a second through hole, and one end of the bolt passes through the first through hole and the second through hole to be connected with the nut. It should be noted that the head of the bolt is hinged to the slider 43 through a telescopic rod 47. On the one hand, when the nut is tightened, the self-rotation of the bolt can be limited. On the other hand, it can also avoid the problem of the bolt falling off and being lost due to loosening the nut.
[0035] In this embodiment, an auxiliary rod 48 is provided on the nut, and the auxiliary rod 48 is perpendicular to the bolt. The auxiliary rod 48 is used to assist the staff in tightening the nut so that the nut can be tightened without the aid of tools.
[0036] In this embodiment, in order to ensure the stability of the slider 43 during the sliding process, a limit groove 50 is dug on the groove wall of the displacement groove 42, and a limit block 49 is integrally connected to the slider 43. The limit block 49 is a ladder-shaped structure, and the limit block 49 is clamped in the limit groove 50. At the same time, the limit block 49 can move along the limit groove 50 accordingly with the displacement of the slider 43. The limit block 49 can also limit the slider 43 from falling off from the opening of the displacement groove 42, thereby improving the connection strength between the slider 43 and the slideway 41.
[0037] In the present embodiment, an elastic pad 51 is provided at the end of the slider 43 facing the device under test 20, and the slider 43 abuts against the top of the device under test 20 through the elastic pad 51, so as to protect the device under test 20 through the elastic pad 51, and prevent the slider 43 from acting on the device under test 20 with excessive force and causing damage to the device under test 20. It should be noted that in order to further enhance the protective effect of the elastic pad 51 on the device under test 20, the surface area of the elastic pad 51 is designed to be larger than the end face area of the slider 43, so as to achieve a larger area of contact with the top of the device under test 20 and better disperse the force provided by the slider 43.
[0038] In this embodiment, the mounting frame is a T-shaped structure, and the mounting frame includes a first plate body 61 and a second plate body 62 which are perpendicular to each other. The first plate body 61 is connected to the test bench 30 through the second plate body 62, wherein the first plate body 61 is parallel to the surface of the test bench 30, the slide 41 is perpendicular to the first plate body 61, and the slide 41 is perpendicular to the top of the device under test 20.
[0039] In a specific implementation, one end of the adapter board body 10 is inserted into the PCI slot of the device under test 20, and then the slider 43 in the auxiliary fixing structure is slid along the displacement slot 42. When the slider 43 slides to a certain position, the height position of the slider 43 relative to the slideway 41 is limited by the limiting structure to achieve the top contact of the slider 43 with the device under test 20, thereby ensuring that the connection between the adapter board body 10 and the PCI slot is not easy to loosen, thereby avoiding the corresponding test errors that affect the test efficiency.
[0040] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the transfer flexible circuit board of the present application has only the above-mentioned single implementation process. On the contrary, as long as the transfer flexible circuit board of the present application can be implemented, it can be included in the feasible implementation plan of the present application.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
