[0022] It should be noted that, unless there is a conflict, the embodiments in this application and the features described in the embodiments can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship and movement status of the various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0024] In addition, in this utility model, the terms "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.
[0025] Please refer to Figures 1 to 7 The high-reliability FBC connector of the embodiment of the present invention includes a cable and two sets of connectors.
[0026] The connector includes an inner core, a main body, and a plurality of signal terminals. The inner core and main body are molded using plastic injection molding. The inner core is located within the main body, that is, the main body is covered by the inner core and the signal terminals. The inner core is provided with a plurality of terminal slots corresponding to each signal terminal. The signal terminals are installed in the terminal slots, and the corresponding cables are electrically connected to the signal terminals of the two sets of connectors. The utility model preferably has a double-row, multi-pin modular design, press fit / dip / SMT PCB connection method, FFC board-to-board flexible connection, and a non-pluggable integrated structure.
[0027] As an embodiment, the signal terminal is composed of a first conductive part, an embedded part, and a second conductive part connected in sequence. The front end of the first conductive part is located outside the main body, the embedded part is installed on the terminal slot, and the second conductive part is welded to the corresponding cable.
[0028] As an embodiment, a snap point is provided on the embedded portion, and a corresponding snap point groove is provided in the terminal groove. The snap point design of the utility model increases the holding force on the plastic and prevents the signal terminal from falling off during the welding process.
[0029] In one embodiment, the signal terminals are arranged side by side in one or more rows. The flat cable is a flexible flat cable. The flat cable has a single-layer or multi-layer structure. The front end faces of the signal terminals in the same row are preferably coplanar, and the front end faces (i.e., the front end faces of the first conductive portions) of the signal terminals in different rows are preferably coplanar. When the signal terminals are arranged in two rows, the second conductive portions of the signal terminals in the two rows are respectively welded to the front and back sides of the flat cable. In a specific implementation, if the flat cable has three or more layers, the signal terminals can be arranged in three or more rows accordingly.
[0030] As an embodiment, a snap is provided at the bottom of the main body to facilitate the user to quickly install the high-reliability FBC connector on the PCB board.
[0031] The preparation method of the high-reliability FBC connector of the present invention includes steps 1 to 3.
[0032] Step 1: Prepare the inner core, signal terminals, and cables.
[0033] Step 2: Press the signal terminal into the terminal groove of the inner core to obtain the inner core equipped with the signal terminal.
[0034] Step 3: Solder the inner cores with signal terminals to the ends of the cable, then injection mold the connector body. Cool the connector to create a highly reliable FBC connector. The signal terminals are soldered to both ends of the cable using a hot-bar welding process to ensure a highly reliable connection between the cable and the terminals. After soldering, the cable is then assembled with the inner cores and molded.
[0035] The utility model can meet the requirements of miniaturized design and realize high-density transmission.
[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
