[0002] A flexible printed circuit board is a circuit board made of a flexible substrate, having good bendability and deformability. When in use, the flexible printed circuit board can be folded through its good bendability and deformability, and occupies less space after folding. The flexible printed circuit board mainly consists of a body, a connecting member, and connecting terminals. When connecting, the connecting terminals on the connecting member are connected to electronic devices.

[0003] During the transportation of the flexible printed circuit board, the connecting terminals may rub against each other, easily causing wear of the connecting terminals, resulting in poor contact after the flexible printed circuit board is connected. Therefore, the present application provides a foldable flexible printed circuit board to meet the requirements. Summary of the Utility Model

[0006] A foldable flexible printed circuit board includes a circuit board body and a connecting member fixed to the end of the circuit board body. Connecting terminals are provided on the surface of the connecting member, and further includes:

[0007] A protection mechanism, the protection mechanism includes a protective sleeve. When the circuit board body is in transportation, the protective sleeve is movably sleeved on the surfaces of the connecting member and the connecting terminals to protect the connecting terminals. When the circuit board body is in use, the protective sleeve is movably sleeved at the bending part of the circuit board body to protect the bending part of the circuit board body.

[0008] Preferably, curved surface grooves are formed at both the top and the bottom of the protective sleeve.

[0009] Preferably, anti-slip stripes are provided on the surface of the curved surface grooves.

[0010] Preferably, a plurality of H-shaped pads are fixed to the top inner wall of the protective sleeve. The H-shaped pads are distributed in a staggered manner with the connecting terminals. When the protective sleeve protects the connecting terminals, the H-shaped pads are attached to the top of the connecting member to support the protective sleeve. When the protective sleeve protects the circuit board body, the H-shaped pads are attached to the surface of the circuit board body.

[0011] Preferably, triangular grooves are formed in the inner wall of the H-shaped pads.

[0012] Preferably, a plurality of limiting ropes are fixed to one end of the protective sleeve away from the circuit board body.

[0013] Preferably, a tear opening is provided at the middle part of the limiting rope.

[0014] Preferably, the intervals between the plurality of limiting ropes are the same.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above solution, through the protection mechanism, during transportation, the protective sleeve is located on the surface of the connecting piece, which can protect the connecting terminal, avoid the connecting terminal from being worn, and avoid the occurrence of poor contact after the circuit board is connected. Secondly, during connection, the protective sleeve can be located at the folding part of the connecting plate body, and the protective sleeve protects the folded part, and the curved surface groove on the surface of the protective sleeve can adapt to the deformation of the protective sleeve, and the protection effect is better during use.

[0017] By providing the H-shaped cushion block, the H-shaped cushion block separates the protective sleeve from the connecting terminal, so that while the protective sleeve protects the connecting terminal, the protective sleeve does not contact the connecting terminal, further avoiding the wear of the connecting terminal.

[0018] By providing the limiting rope, the limiting rope can make the protective sleeve just fit on the surface of the connecting piece, ensuring the protection effect. And when the protective sleeve needs to move towards the circuit board body, the limiting rope is pulled off through the tear opening, making the use more convenient.

[0034] Such as Figures 1-6As shown, an embodiment of the present utility model provides a foldable flexible printed circuit board, which includes a circuit board body 1 and a connecting member 2 fixed at the end of the circuit board body 1. A connection terminal 3 is provided on the surface of the connecting member 2, and further includes:

[0035] A protection mechanism 4, which includes a protective sleeve 5. When the circuit board body 1 is in transportation, the protective sleeve 5 is movably sleeved on the surfaces of the connecting member 2 and the connection terminal 3 to protect the connection terminal 3. When the circuit board body 1 is in use, the protective sleeve 5 is movably sleeved at the bending portion of the circuit board body 1 to protect the bending portion of the circuit board body 1. The protective sleeve 5 is a rubber sleeve.

[0036] As Figures 3-5 shown, in this embodiment, curved surface grooves 6 are provided at both the top and bottom of the protective sleeve 5, making the middle part of the protective sleeve 5 thinner and making it easier for the middle part to deform when the protective sleeve 5 is bent.

[0037] As Figures 3-5 shown, in this embodiment, anti-slip stripes are provided on the surface of the curved surface groove 6 to increase the friction with the fingers and avoid slipping of the hand when moving the protective sleeve 5.

[0038] As Figure 6 shown, in this embodiment, a plurality of H-shaped pads 7 are fixed to the top inner wall of the protective sleeve 5. The H-shaped pads 7 are distributed in a staggered manner with the connection terminal 3. When the protective sleeve 5 protects the connection terminal 3, the H-shaped pads 7 are attached to the top of the connecting member 2 to support the protective sleeve 5. When the protective sleeve 5 protects the circuit board body 1, the H-shaped pads 7 are attached to the surface of the circuit board body 1. The H-shaped pads 7 can prevent the protective sleeve 5 from contacting the connection terminal 3 and prevent the protective sleeve 5 from wearing the connection terminal 3, further protecting the connection terminal 3.

[0039] As Figure 8 shown, in this embodiment, triangular grooves 8 are provided on the inner wall of the H-shaped pad 7. The triangular grooves 8 are provided at the top inner wall and the bottom inner wall of the H-shaped pad 7 to adapt to the bending of the H-shaped pad 7 and avoid extrusion at the bending portion of the H-shaped pad 7.

[0040] As Figure 4 and Figure 7 shown, in this embodiment, a plurality of limiting ropes 9 are fixed to one end of the protective sleeve 5 away from the circuit board body 1. By providing the limiting ropes 9, the protective sleeve 5 is completely sleeved on the surface of the connecting member 2 to prevent the protective sleeve 5 from exceeding the connecting member 2.

[0041] As Figure 4 and Figure 7 shown, in this embodiment, a tearing opening 10 is provided at the middle part of the limiting rope 9. Through the tearing opening 10, the limiting rope 9 can be quickly broken from the middle, making it more convenient to use.

[0042] AsFigure 4 As shown, in this embodiment, the spacing between several limiting ropes 9 is the same, making the appearance more beautiful and the force application more uniform during use.

[0043] Working principle: After the circuit board body 1 is produced, the protective sleeve 5 is sleeved on the surface of the connecting member 2. After sleeving, the H-shaped cushion block 7 is located between the connection terminals 3. During use, the protective sleeve 5 protects the connection terminals 3, and when the protective sleeve 5 is sleeved, the limiting rope 9 limits the protective sleeve 5.

[0044] When the circuit board body 1 needs to be installed, the limiting rope 9 is disconnected through the tearing opening 10, and then the protective sleeve 5 is moved towards the circuit board body 1 to move the protective sleeve 5 to the position where the circuit board body 1 needs to be folded. Then, the circuit board body 1 is installed through the connection terminals 3 on the connecting member 2.

[0045] When the protective sleeve 5 protects the folding part of the circuit board body 1, the protective sleeve 5 deforms through the curved surface groove 6 to avoid affecting the folding of the circuit board body 1. And when the protective sleeve 5 is bent, the triangular groove 8 on the H-shaped cushion block 7 causes the H-shaped cushion block 7 to deform, avoiding extrusion of the H-shaped cushion block 7 at the bending part.

[0046] The present utility model covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of the present utility model. For the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without these detailed descriptions.

[0047] The above description is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
