軟性電路板Flexible circuit board

本發明係有關一種軟性電路板，尤指一種在接點側的補強板具有臂部的軟性電路板。The present invention relates to a flexible circuit board, and more particularly to a flexible circuit board having an arm portion on a contact side reinforcing plate.

在現有的電子裝置中，常使用軟性電路板(flexible printed circuit,FPC)來電性連接兩元件/模組。例如在顯示面板中，背光模組的光源元件(light bar)即利用FPC連接於顯示面板的控制電路板的連接器上以達成電性導通。而這種常用的FPC連接端在插入電路板的連接器後，由於僅利用連接器上的鋼琴蓋元件卡合固定，在使用上很容易發生鋼琴蓋鬆脫，導致FPC連接端與連接器分開而形成開路(open)，以致電性無法導通。因此目前在現有技術中，當FPC連接端插入連接器，以鋼琴蓋元件卡合後，會另外將一透明的FPC膠帶貼在FPC連接端與連接器之間，以防止FPC連接端脫落。但這樣的作法使得FPC連接端拆裝時，必須先將FPC膠帶撕下來，再翻開鋼琴蓋元件及拉出FPC連接端，然後再重新裝上FPC連接端，再將FPC膠帶對準貼回。如此反覆的步驟明顯增加重工的時間，且增加組裝以及測試的複雜度。In the existing electronic devices, a flexible printed circuit (FPC) is often used to electrically connect two components/modules. For example, in the display panel, the light bar of the backlight module is connected to the connector of the control circuit board of the display panel by FPC to achieve electrical conduction. However, after the conventional FPC connector is inserted into the connector of the circuit board, since the piano cover component is only fixed by the connector on the connector, the piano cover is easily released in use, and the FPC connector is separated from the connector. The open is formed, and the callability cannot be turned on. Therefore, in the prior art, when the FPC connector is inserted into the connector, after the piano cover member is engaged, a transparent FPC tape is additionally attached between the FPC connector and the connector to prevent the FPC connector from coming off. However, in this way, when the FPC connector is disassembled, the FPC tape must be peeled off, then the piano cover component is opened and the FPC connector is pulled out, and then the FPC connector is reinstalled, and the FPC tape is aligned and pasted. . Such repeated steps significantly increase the time of rework and increase the complexity of assembly and testing.

本發明提供一種軟性電路板，用來插入連接於一連接器，該連接器具有一連接側以及相對該連接側之一抵靠側，且該連接側包含複數個電子接點。該軟性電路板包含有一本體、複數個接點以及一補強板。該本體具有一連接端。該複數個接點設置於該連接端上，該複數個接點插入該連接器的該連接側之該複數個電子接點以連接於該連接器。該補強板設置於該連接端，該補強板具有一臂部，當該複數個連接點插入該連接器的該連接側時，該臂部位於該抵靠側且該連接器的該抵靠側止抵該臂部。The invention provides a flexible circuit board for inserting and connecting to a connector having a connecting side and an abutting side opposite to the connecting side, and the connecting side comprises a plurality of electronic contacts. The flexible circuit board comprises a body, a plurality of contacts and a reinforcing plate. The body has a connecting end. The plurality of contacts are disposed on the connection end, and the plurality of contacts are inserted into the plurality of electronic contacts on the connection side of the connector to be connected to the connector. The reinforcing plate is disposed at the connecting end, and the reinforcing plate has an arm portion. When the plurality of connecting points are inserted into the connecting side of the connector, the arm portion is located on the abutting side and the abutting side of the connector Stop the arm.

藉由本發明所揭露的軟性電路板，在軟性電路板連接於電路板上的一連接器時，軟性電路板上的補強板的臂部受到連接器的側邊抵靠，使軟性電路板無法直接自連接器拔出，增加軟性電路板在連接於連接器時的固定性，可節省現有技術中需要額外利用膠帶固定的組裝步驟，降低重工時間以及組裝、測試的複雜度。According to the flexible circuit board disclosed in the present invention, when the flexible circuit board is connected to a connector on the circuit board, the arm portion of the reinforcing plate on the flexible circuit board is abutted by the side of the connector, so that the flexible circuit board cannot be directly Pulling out from the connector increases the fixing of the flexible circuit board when it is connected to the connector, which saves the assembly steps required in the prior art to additionally utilize the tape fixing, reduces the rework time, and the complexity of assembly and testing.
