DETAILED DESCRIPTION
[0020] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Please combine Figures 1 to 5 , a touch screen FPC structure that is convenient for connecting to a client in this embodiment includes a touch screen, an FPC flexible connection board 2 is provided on one side of the touch screen, the FPC flexible connection board 2 includes a touch screen connection terminal 3, a circuit control terminal 4 and an information export terminal 5, a circuit board 1 is provided on the circuit control terminal 4, an electrical component 6 is provided on one side of the circuit board 1, an FPC bending area 7 is provided on the end of the circuit control terminal 4 close to the touch screen connection terminal 3, a PI reinforcement area 8 is provided on the end of the information export terminal 5 away from the circuit control terminal 4, and a reinforcing sheet 12 is provided on the PI reinforcement area 8.
[0022] The information export terminal 5 is composed of a straight line and a U-shape, and the PI reinforcement area 8 is located at one end of the U-shape. It should be noted here that the information export terminal 5 is designed through a combination of a straight line and a U-shape, which effectively facilitates the winding of the FPC, and facilitates the FPC flexible connection board 2 to be changed from right-side plug-in to top plug-in when bending, so that the information export terminal 5 can lead out of the PI reinforcement area 8. During use, the size of the straight line and the U-shape needs to match the position of the connector of the whole machine, and an assembly tolerance of ±1mm needs to be reserved for easy assembly.
[0023] A metal reinforcement sheet 9 is provided on the circuit control terminal 4 and is located on the lower surface of the electrical component 6 . A conductive adhesive 11 is provided on the bottom end of the metal reinforcement sheet 9 .
[0024] The metal reinforcement plate 9 and the reinforcement plate 12 are both made of steel sheets, which effectively make the circuit control terminal 4 and the information export terminal 5 have high hardness and improve the service life. Through the design of the reinforcement plate 12, it is convenient to play a fixing role when plugging in the information export terminal 5, and it is convenient to hold and plug in when plugging in the instruction export information export terminal 5, making it convenient to plug in.
[0025] One side of the circuit board 1 is provided with an antistatic release film 10 located on the periphery of the electrical component 6. The antistatic release film 10 plays an antistatic role and protects the electrical component 6. The protection effect is good and the practicability is strong.
[0026] Anti-interference electromagnetic films 13 are provided on the FPC bending area 7 and the straight-line shape of the information lead-out end 5. The anti-interference electromagnetic films can play an electromagnetic anti-interference role on the FPC flexible connecting board 2, making its anti-interference effect better and improving practicality.
[0027] In the embodiment of the present application, the implementation principle of a touch screen FPC structure that is convenient for connecting to the client is as follows: when in use, the design of the FPC bending area 7 facilitates the bending of the FPC flexible connecting board 2, so that the FPC flexible connecting board 2 can drive the PI reinforcement area 8 on the information export end 5 to change its position, so that the touch screen FPC connected to the client can be wrapped out from the side, and then the plug-in direction can be changed by changing the position of the PI reinforcement area 8. When the touch screen FPC is wrapped from the side to the top, it effectively facilitates the connection with the client connector, effectively completing the FPC structure design that can arbitrarily switch the FPC connection direction, thereby effectively meeting the customer's needs for arbitrarily switching the plug-in direction.
[0028] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
