DETAILED DESCRIPTION

[0027] 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. Example

[0028] See Figures 1 to 3 As shown, a plug-in roll-up soft substrate includes a first flexible circuit board 1 and a second flexible circuit board 2, and a plug-in limiting structure 3 is arranged between the first flexible circuit board and the second flexible circuit board; in this embodiment, the first flexible circuit board and the second flexible circuit board can be stored in a roll, which improves its scope of application and facilitates transportation and packaging.

[0029] The plug-in limiting structure 3 includes a plug-in socket 31, a positioning pressure plate 32 and a plurality of positioning pins 33; and in actual application, the plug-in socket is an insulating plastic structure. The positioning pressure plate and the plurality of positioning pins are also insulating plastic structures. The plug-in socket is provided with a first plug-in slot 4 and a second plug-in slot 5 arranged in an upper and lower manner; the top surface of the plug-in socket is provided with a guide column 6, and the positioning pressure plate is provided with a guide hole 7; the plug-in socket is provided with vertical sockets 8 whose number matches the number of the positioning pins, and the vertical sockets pass through the first plug-in slot and the second plug-in slot; in this embodiment, because the thickness of the first flexible circuit board and the second flexible circuit board is relatively thin, the thickness of the plug-in socket only needs to meet the insertion of the first flexible circuit board and the second flexible circuit board, so the thickness can be processed as needed, and at the same time, the height of the guide column can also be processed as needed.

[0030] During installation and use, the first flexible circuit board and the second flexible circuit board are respectively inserted into the first plug-in slot and the second plug-in slot from the symmetrical sides of the plug-in seat; and the positioning pin is fixed to the bottom surface of the positioning pressure plate, and the positioning pressure plate is on the top surface of the plug-in seat, and the guide column is in the guide hole position, the positioning pressure plate is pressed downward, and the positioning pin is plugged into the vertical plug hole and positions the first flexible circuit board and the second transparent circuit board. The guide column cooperates with the guide hole position mainly to ensure the stability of the lifting and lowering of the positioning pressure plate to prevent it from shifting or tilting. At the same time, the positioning pin and the vertical plug hole are mainly used to plug and position the first flexible circuit board and the second transparent circuit board to prevent them from loosening or falling off. In this embodiment, the diameter of the positioning pin matches the inner diameter of the vertical plug hole. The positioning pin is inserted into the vertical plug hole and positioned by the friction between the two. The positioning pin is mainly limited by the friction with the vertical socket to ensure the stability and reliability of the connection between the two. When the external force is greater than the friction between the two, the positioning pin can be inserted or pulled out, which is highly practical.

[0031] In actual application, the edges of the first flexible circuit board and the second flexible circuit board are provided with connection holes 9; the positioning pin is provided through the connection holes. In this embodiment, when inserting, the position of the connection hole can be checked from the vertical plug hole on the bottom surface of the socket, and when the connection hole and the vertical plug hole are on the same vertical line, the positioning pin can be inserted.

[0032] In order to facilitate the electrical connection between the first flexible circuit board and the second transparent circuit board, a conductive rod 10 is integrally formed in the socket, and the conductive rod is staggered with the vertical socket; conductive ejector pins 11 are arranged at both ends of the conductive rod; the conductive ejector pins are conventional structures of the prior art, so they are not described in detail; conductive gold fingers 12 are arranged at the end edges of the first flexible circuit board and the second flexible circuit board; the conductive ejector pins are inserted into the conductive gold fingers to electrically connect the first flexible circuit board and the second flexible circuit board. The electrical connection between the two can be guaranteed as needed, and the practicability is strong.

[0033] The utility model has positive effects: the utility model has a reasonable structure, is provided with a plug socket, and has a first plug slot and a second plug slot arranged thereon in an upper and lower manner. When in use, the first flexible circuit board and the second flexible circuit board can be respectively inserted into the first plug slot and the second plug slot, and the two can be positioned by cooperating with the positioning pressure plate and the positioning pin, thereby improving the effectiveness of plugging and the stability and reliability of plugging, and also being conducive to improving the efficiency of plugging, and having strong applicability and good practicality;

[0034] Moreover, it is also provided with a conductive rod matched with a conductive ejector pin, which can be electrically connected with the conductive gold fingers on the first flexible circuit board and the second flexible circuit board as needed, thereby meeting the needs of electrical connection and having strong practicality.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
