Description of the Invention: [Technical Field of the Invention] The present invention relates to a connector and an associated fixed module thereof, and more particularly to a connector detachably coupled to a printed circuit board and its associated fixed module . [Prior Art] Many devices and interfaces can be smoothly connected, and various types of connectors are widely used - many electronic related products, such as motherboards and various interface cards, and most of the connections H are based on the observations. The connection between the electronic products is used to connect the electronic products, and the connector for connecting the flexible circuit board is added. The connector with the printed circuit board (pCB) is equivalent. A representative example. #一叙和s 'The combination of a flexible circuit board and a printed circuit board must use a board to board connector or a board connector (Fpc-connector), however In the connection between the flexible circuit board and the printed circuit board, whether it is connected by a board-to-board connector or a soft-board connector, since the connection is made by using the male-female connection y, the flexible circuit board and the printing are performed. The structure generated after the circuit board is connected occupies a small space inside the related electronic product, for example, on the board, and the flexible circuit board is connected with the printed circuit board. The height of the structure is about 4 [S3 1360933 l, about 35 mm'. For a soft-board connector, the height of the structure is about i ^. 胄 In view of this, if there is sufficient space inside the electronic product but the height is insufficient, • The design of the connection using the board-to-board connector or the soft-board connector can be replaced by the heat, which is to set the contact piece on the flexible circuit board and the circuit board. The hot tin plate is superposed on the opposite side, and then hot pressed by the hot pressing head to heat-melt the hot-melt J1 tin sheet x, and the molten hot-melt tin sheet is cooled and solidified to adhere to the contact pad. After that, the connection between the flexible circuit board and the printed circuit board can be completed. This method can reduce the structural height of the flexible circuit board and the printed circuit board to about 0.5 mm, but due to the flexible circuit board and the printed circuit board. After the hot pressing process, it has been fixed and not detachable, so it will bring about a certain amount of money for the subsequent group dressing, rework, bending and mixing, and the soft electricity connected by the hot pressing process. The board and the printed circuit board need to be tested by the pull-out force to prevent the soft power transmission from falling off the circuit board. Therefore, the hot tin plate on the printed circuit board usually needs a larger setting area, thereby strengthening The bonding force on the flexible circuit board to contact the cymbal, but this will limit the space available for the circuit configuration on the printed circuit board, thereby causing difficulties in the design of the relevant circuit configuration. In summary, the flexible circuit board and the printed circuit In terms of board connection, whether it is a male-female joint or a hot-pressing method, each has its own shortcomings. Therefore, in the current trend that various electronic consumer products are required to be light and short, how to design to reduce the occupation of the connector The structure of the space and at the same time avoiding the above mentioned problems is now

There is a hole 32' and the substrate 22 is divided into a corresponding positioning opening = the service coffee _2 - the coffee (3), the training 22 series can be: with: 0 and the alignment column 34 between the alignment Accurately stuck in the printed circuit = ^; hole 36 _ to the hole 32, thereby locating a plurality of second pieces of the aged metal piece 26 and the _ board 14 of the second message: the thermocompression bonding of the transfer piece 20 position. In addition, the number of the column % and the number of the pressing holes 36 on the connector 16 may not be limited to one. For example, as shown in FIG. 3, it may be added to the circuit of _ ' The positioning opening 3 on the printed circuit board 12 of the board 14 is also required to be added to two, so that the alignment between the flexible circuit board 连接, the connector 16 and the printed circuit board 12 can be further improved. Accurate. The following is a detailed description of the assembly and disassembly of the needle-alignment module 1G. Please refer to FIG. 4 for more details. FIG. 4 is a partial enlarged view of the flexible circuit board 14 and the connector π shown in FIG. 1 , and the flexible circuit board 14 is mounted on the printed circuit board I2 in the _ connector (4). First, a common hot stage is used to connect the plurality of hot melt metals 426 of the connector π to the soft 2, respectively. . The so-called hot_process is on the printed circuit board: tin: the first = softer (four) way board with hot __ on the printed circuit board where the 'bad' pure _ saki _ circuit board of wealth, off: f Adhered between the printed circuit board and the _ road board, _ cream cooling solid = i can be fixed on the printed circuit board by solder paste, plus tin ^, so between the printed circuit board and the flexible circuit board It is possible to use the tin crucible to achieve the connection and electrical conduction at the same time. In summary, in the present invention, the positioning module 32 on the circuit board of the present invention is aligned with the connector 16 to form a plurality of second transmission pads 20 on the flexible circuit board 14. The plurality of metal sheets % ' on the substrate 22 can be respectively aligned in a one-to-one manner, and then can be hot pressed onto the connector 16 by using a pressing head according to the above-mentioned process, so that the The plurality of heat-resistant metal sheets 26 on the thermal head are waited for a plurality of first-cooling and attached to the corresponding plural/shock transmission on the board 14 to complete the flexible circuit board. The connection between 14 and the connection = is shown in Fig. 5, and the fifth embodiment is a schematic view in which the flexible circuit board 14 is joined with the connector 16. . . Figure 6 is a schematic view of a portion of the flexible circuit board shown in Figure 5, which is snapped onto the printed circuit board 12 by the =16. The fixing device 24 on the Lianyi^6 is used to engage the flexible circuit board 14 on the printed circuit board, and the positioning post 34 on the connector 16 as shown in FIG. 3 is first aligned as shown in the 1360933 figure. The positioning opening of the printed circuit board 12, for example, then snaps the solid through 4 of the connector π into the side of the printed circuit board 12 (as shown in FIG. 6). At this time, the positioning post on the connector 16 34 can also be buckled into the positioning opening 3 of the printing plate 12 at the same time, so that not only the fixing device % can be used to make the connection @μ snap onto the printed circuit board 12, but also can be utilized as shown in FIG. The fixture 2 is used to clamp the upper and lower sides of the printed circuit board U, so that the engagement between the printed circuit board U and the connector 16 is more stable, and the contact elastic piece π has elasticity and can be mixed with the assembly softness. The distance between the board and the printed circuit board U is intended to fine tune the distance between the flexible circuit board 14 and the printed circuit board 12. In addition to the shape, the alignment between the positioning post 34 on the connector 16 and the positioning opening 3 on the printed circuit board 12 can also be made on the connector while the connector 16 is snapped onto the printed circuit board. The plurality of contact springs 28 can accurately contact the plurality of first signal transmission pads 18 on the printed circuit board 12 in a one-to-one manner, so that the first signal transmission pads 18 on the printed circuit board a can pass through the connector. The plurality of contact spring pieces 16 and the plurality of hot-melt metal pieces 26 are further electrically connected to the plurality of second signal transmission pads 20 on the flexible circuit board 14. Next, if it is necessary to separate the flexible circuit board Μ from the printed circuit board 12 in response to the demand for subsequent electronic product assembly or heavy work, it is only necessary to pull the connector when the human H is mixed with _ money 24, __ The direction of the positioning hole 30 on the circuit board u is moved, so that the flexible circuit board 14 can be detached from the printing board 12 for continuous assembly or rework. In short, the present invention engages a connector to which a flexible circuit board is bonded to a printed circuit board by first bonding a flexible circuit board and a connector using a hot stamping process and then using a fixing device on the connector and contacting the elastic piece. The side is connected to the flexible circuit board and the printed circuit board, so that the connector of the present invention can provide a flexible circuit board and a printed circuit board as compared with the prior art. The height of the connected structure is further reduced from about mm mm to about 35 mm to about 0.8 mm, and the connection H provided by the present invention can be connected to the red 岐 device in comparison with the prior art using the hot pressing process. The design of the disassembled ground on the printed circuit board is used to solve the problem that the wire technology is connected to the flexible circuit board and the printed circuit board brings the inability to disassemble the side. In addition, compared with the prior art, Lai County (4) It is necessary to set the area of the older metal 4, because the connection of the X-month and the 供 can be increased by the fixing device of the connection II and the upper and lower clamping of the contact elastic piece. The fixing force of the pair of circuit boards is increased, so that the area on the side of the first signal transmission pad on the printed circuit board can be correspondingly reduced, thereby increasing the design flexibility of the printed circuit board in the circuit routing configuration.
