Description

Technical Field

[0001] The utility model relates to the technical field of reinforcing steel sheets, in particular to a key reinforcing steel sheet with stable installation. Background Art

[0002] Flexible printed circuit (FPC), also known as soft printed circuit board, flexible printed circuit board, has excellent characteristics such as light weight, thin thickness, and free bending and folding. The reinforcing steel sheet is attached to a certain position or area of ​​the FPC flexible circuit board to increase the thickness in order to enhance the mechanical strength of the FPC and facilitate surface mounting of parts.

[0003] The existing reinforcing steel sheets play a role in positioning and fixing the reinforcing steel sheets through the positioning glue, pressing columns, positioning structures and fixing ports. For example, Chinese patent application No. CN202122726203.7 discloses a mobile phone reinforcing steel sheet with an installation positioning structure, including a reinforcing steel sheet and a positioning structure. Positioning structures are provided on both sides of the front and rear end surfaces of the reinforcing steel sheet, and there are four positioning structures. Limiting plates are provided on both sides of the reinforcing steel sheet, and there are four limiting plates. A bending port is provided on the reinforcing steel sheet, and there are five bending ports, and a first fixing port is provided on one side of the bending port.

[0004] This reinforcing steel sheet needs to be positioned and fixed in sequence using positioning glue, a pressing column, a positioning structure, and a fixing port. The operation steps are relatively complicated, which makes the installation of the reinforcing steel sheet more troublesome. Utility Model Content

[0017] By setting up structures such as side panels and limit plates, the patch is moved to the position corresponding to the button, and the side of the FPC board is inserted between the limit plate and the patch. At this time, the side of the FPC board is fitted with the side panel, so that the side panel is parallel to the side of the FPC, thereby preventing the patch from shifting. The limit plate and the FPC board can be connected by heating the upper thermosetting adhesive. Compared with the prior art, the side panel and the FPC board are made parallel by fitting, which can prevent the patch from shifting and ensure the stability of the installation. The limit plate and the FPC board can be initially connected and fixed by heating the upper thermosetting adhesive. Subsequently, the patch and the FPC board can be connected and fixed by hot pressing, and the reinforcing steel sheet is more convenient to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: a key reinforcement steel sheet with stable installation, including a patch 1, a side plate 2 is connected to one side of the upper surface of the patch 1, a limiting plate 3 is connected to the side of the side plate 2 close to the patch 1, a space is left between the limiting plate 3 and the patch 1, thermosetting glue 4 is provided on the side of the limiting plate 3 and the patch 1 facing each other, a space is left between the thermosetting glue 4 on the upper and lower sides, the patch 1 is made of stainless steel, and the length of the side plate 2 is less than the length of the patch 1.

[0025] During operation, patch 1 is moved to the position corresponding to the button, and the side of the FPC board is inserted into the gap between the limit plate 3 and patch 1, so that the side of the FPC board fits with the surface of the side plate 2. At this time, patch 1 is aligned with the button, and the side plate 2 is flush with the side of the FPC board. Use an electric soldering iron to heat both sides of the upper surface of the limit plate 3 so that the thermosetting adhesive 4 at the corresponding position is connected to the FPC board, thereby playing a role of single-point positioning. Subsequently, the thermosetting adhesive 4 on the upper and lower sides can be connected and fixed to the FPC board through hot pressing, so that patch 1 is fixed on the FPC board. At this time, patch 1 can reinforce the button.

[0026] See also Figure 1-4 The utility model provides a technical solution: auxiliary rings 5 ​​are symmetrically coated on both sides of the upper surface of the limiting plate 3, and the auxiliary rings 5 ​​are coatings.

[0027] During operation, through the setting of the auxiliary ring 5, the electric soldering iron heats the inner side of the auxiliary ring 5 when in use. Since the two auxiliary rings 5 ​​are symmetrical, the symmetry of the single-point positioning is ensured.

[0028] See also Figure 1-4 The utility model provides a technical solution: a slot hole 6 is formed through the upper surface of the limiting plate 3 .

[0029] During operation, through the arrangement of the slot hole 6 , it can be observed through the slot hole 6 whether the side edge of the FPC board is flush with the surface of the side plate 2 .

[0030] See also Figure 1-4 The utility model provides a technical solution: a groove 7 adapted to the side plate 2 is opened on the side of the patch 1 close to the side plate 2, and the lower surface of the side plate 2 extends into the groove 7.

[0031] During operation, the side panel 2 can be inserted into the groove 7 through the setting of the groove 7, and then the side panel 2 and the groove 7 can be fixed by glue or other means, so as to facilitate the connection and fixation of the side panel 2 and the patch 1.

[0032] See also Figure 1-4 The utility model provides a technical solution: the auxiliary ring 5 is painted red.

[0033] During operation, the red auxiliary ring 5 is easily observed by the assemblers, which helps them to penetrate the position of the auxiliary ring 5 .

[0034] See also Figure 1-4 The utility model provides a technical solution: convex blocks 8 are provided on both sides of the side plate 2, and the convex blocks 8 are fitted with the upper surface of the patch 1.

[0035] During operation, the side plate 2 can be limited by the setting of the protrusion 8, ensuring that the side plate 2 stays at a corresponding height after being inserted into the groove 7.

[0036] See also Figure 1-4 The utility model provides a technical solution: the side plate 2 is made of 304 stainless steel.

[0037] When working, 304 stainless steel has weak magnetism and is not likely to affect magnetically sensitive products such as motors.

[0038] In summary, move patch 1 to the position corresponding to the button, insert the side of the FPC board into the gap between the limit plate 3 and the patch 1, so that the side of the FPC board fits with the surface of the side panel 2. At this time, patch 1 is aligned with the button, and the side panel 2 is flush with the side of the FPC board. The slot 6 can be used to observe whether the side of the FPC board is flush with the surface of the side panel 2. Use an electric soldering iron to heat the inner position of the auxiliary ring 5 to connect the thermosetting adhesive 4 at the corresponding position to the FPC board, thereby playing a role of single-point positioning. Subsequently, the thermosetting adhesive 4 on the upper and lower sides can be connected and fixed to the FPC board through hot pressing, so that the patch 1 is fixed on the FPC board. At this time, the patch 1 can reinforce the button.
