DETAILED DESCRIPTION OF THE EMBODIMENTS

To make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and a specific embodiment.

With reference toFIGS. 1 and 2, the exemplary embodiment in the present disclosure provides an FPCB plug-in jig1, including a fixture part for clamping an FPCB, wherein the fixture part includes a first clamping element10and a second clamping element20which are arranged oppositely. The first clamping element10and the second clamping element20are configured such that an opening12is formed at one end of the fixture part and a pressing portion11is formed at the other end of the fixture part. As shown inFIG. 1, the end with the opening12is positioned on the right side of the FPCB plug-in jig1in the figure, while the other end with the pressing portion11is positioned on the left side of the FPCB plug-in jig1in the figure, but such a configuration mode is not limiting. A signal matching board40is arranged on a surface of the first clamping element10facing the second clamping element20, and the specific structure thereof is shown inFIG. 2. The signal matching board40is electrically connected, at one end close to the opening12of the fixture part, with the FPCB plugged into the FPCB plug-in jig1. Moreover, an additional signal port42is provided at another end of the signal matching board40close to the pressing portion11of the fixture part.

The structure of the fixture part of the FPCB plug-in jig1in this embodiment is equivalent to a clamp, so the end with the opening12of the fixture part can be opened by pressing the pressing portion11of the fixture part. At the moment, as shown in FIG.1, the FPCB2is plugged into the opened opening12to electrically connect to the signal matching board40. The additional signal port42is formed at the other end of the signal matching board40close to the pressing portion11, so that external signals can be introduced into the FPCB2through the additional signal port42, in order to provide corresponding signals to the display module. The FPCB plug-in jig1in this embodiment is simple in structure, easy to operate, safe and reliable, and can greatly reduce the loss of wires.

Preferably, a probe41is arranged on the signal matching board40at a position where the signal matching board40electrically connecting to the FPCB2. The probe41ensures that the FPCB2can be well electrically connected to the signal matching board40, so as to improve the reliability of the FPCB plug-in jig1.

Preferably, a slot22for accommodating the FPCB2is formed in an end of the second clamping element20close to the opening12of the fixture part. The end of the slot22deep into the second clamping element20from the opening12is equivalent to a retaining wall, which plays a role of fixing the plug-in position of the FPCB2and avoids the situation that the FPCB2cannot be well electrically connected to the signal matching board40due to the inaccurate plug-in position.

Preferably, in the example shown in the figures, when the pressing portion11of the fixture part is subjected to a downward external pressing force, an end of the first clamping element10close to the opening12of the fixture part moves along an opposite direction of the force, while the second clamping element20is immobilized.

That is to say, the fixture part in this embodiment has a structure that is movable on one side and fixed on the other side, so that the clamped FPCB2is more stable.

Preferably, the pressing portion11of the fixture part is provided with friction stripes, thus avoiding pressing difficulty and even failure resulting from the fact that an external force applying body slips from the pressing portion11due to excessive smoothness of the pressing portion11when the external force applying body applies an external force to the pressing portion11.

Preferably, a protective board30is arranged on a side of the signal matching board40facing the second clamping element20, and the protective board30and the first clamping element10are fixed to each other for protecting the signal matching board40.

Preferably, the additional signal port42of the signal matching board40is a detachable port, so that different additional signal ports42for different additional signals can be assembled on the signal matching board40to match different additional signals. That is to say, the FPCB plug-in jig1of this embodiment is applicable to FPCBs of different types, so that the FPCB plug-in jig1of this embodiment has a wider application range.
