Side.
Preferably, the position of non-printed wire is provided with trepanning in the FPC plate bodies.
Compared with prior art, the present invention has the following advantages and beneficial effect：
In the present invention, the high-temperature-resistant layer of FPC plates causes FPC plate high temperature resistants, strong by being set in the outer periphery of FPC plate bodies
Change patch layer, and be fixed with frame so that FPC plates are first subject to this pulling force under tension, by reinforcing patch layer, production
Raw tear resistance avoids the tear of FPC plates, so as to improve the service life of FPC plates.
Description of the drawings
Fig. 1 is the vertical view of FPC plates of the present invention；
Fig. 2 is the A-A views in Fig. 1.
Specific embodiment
Attached drawing describes embodiment of the present invention.Those of ordinary skill in the art will recognize, without departing from
In the case of the spirit and scope of the present invention, described embodiment can be repaiied with a variety of different mode or combinations
Just.Therefore, attached drawing and description are regarded as illustrative in nature, and are not intended to limit the scope of the claims.In addition,
In this specification, attached drawing is drawn not in scale, and identical reference numeral represents identical part.
The present embodiment is described in detail with reference to Fig. 1-Fig. 2.
Fig. 1 is the vertical view of FPC plates of the present invention, and Fig. 2 is the A-A views in Fig. 1, as depicted in figs. 1 and 2, this hair
The bright FPC plates, including FPC plate bodies 1, the neighboring of FPC plate bodies 1 is provided with frame 2, frame 2 and FPC plate bodies 1
Between be provided with strengthen patch layer 3.In FPC plate under tensions, this pulling force is first subject to by reinforcing patch layer 3, is generated anti-tear
Power is split, to prevent FPC plates from tearing, the lear energy of FPC plates is improved, so as to improve the service life of FPC plates.
Since glass wire has higher mechanical strength, it is preferable that strengthen patch layer 3 and include more glass fibres
Line, glass wire can bond together with the neighboring of FPC plate bodies 1.More glass wires can be staggered,
It can also be arranged in parallel, but preferably be arranged in parallel, be fitted closely, and can reduce so as to strengthen patch layer 3 and FPC plate bodies 1
The width of FPC plates reduces it and occupies volume.
For the ease of strengthening the installation of patch layer, it is preferable that frame 2 is integrated with reinforcing patch layer 3, in order to by frame
2 are installed on the periphery of FPC plate bodies 1 with strengthening patch layer 3, and easy to disassemble simultaneously.Frame 2 and the joint place of FPC plate bodies 1
