Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality It applies among a range.
As shown in Figure 1-3, FPC attachment device includes FPC 1, FPC connector 2, FPC 1 is connected to by FPC connector 2 PCB 3。
In the present embodiment, as shown in figure 4, FPC 1 includes ontology 11, stiffening plate 12.Wherein, stiffening plate 12 and ontology 11 are oppositely arranged, and stiffening plate 12 has end to end interconnecting piece 121 and extension 122, and interconnecting piece 121 is layed in ontology 11, Extension 122 is connected to the left side of interconnecting piece 121, and extension 122 is equipped with a holding section 123, and holding section 123 is for blocking Length direction of the FPC 1 relative to FPC connector 2 along stiffening plate 12, width side are limited together in the FPC connector 2 in Fig. 1-3 To the movement with short transverse;When external force of the extension 122 by the disassembly direction 4 in Fig. 1, holding section 123 and FPC connect The separation of 2 phase of device is connect, FPC 1 is removed from FPC connector 2.
In other embodiments, if the width of ontology 11, stiffening plate 12 is larger, in order to be reliably connected at FPC 1 Multiple holding sections 123 can be arranged as needed in FPC connector 2 on extension 122.
In the present embodiment, as shown in figure 4, extension 122 stretches out the left side of ontology 11, and holding section 123 is located at The left side of the left side of ontology 11;Holding section 123 is card slot.
When FPC 1 is inserted into FPC connector 2, extension 122 first generates downwards flexible deformation, then restores elastic change again Shape, so that the card slot is sticked in FPC connector 2;When needing to take out FPC 1 from FPC connector 2, along Fig. 1 Disassembly direction 4 applies external force to extension 122, and extension 122 generates flexible deformation, holding section 123 and 2 phase of FPC connector point From.From the foregoing, it will be observed that holding section 123 can reliably be sticked in FPC connector 2 when FPC 1 is inserted into FPC connector 2;When need When taking out FPC 1 from FPC connector 2, FPC 1 can be removed more conveniently again.
The notch is simple, it is only necessary to the structure to match with the card slot be arranged on FPC connector 2, just can So that FPC 1 is reliably sticked in FPC connector 2, cost is relatively low.
In the present embodiment, as illustrated in figures 1-3 and 5, FPC connector 2 include shell 21, shell 21 have bottom, Top and two side walls, two side walls are oppositely arranged and are adjacent to the bottom and top, the bottom, the top Accommodating space is surrounded between two side walls, the accommodating space is for accommodating FPC 1, and ontology 11 is located at stiffening plate 12 Between the bottom;The bottom surface at the top is equipped with a limiting section 22, and limiting section 22 is used to match to come with holding section 123 Limitation FPC 1 moving along the length direction of stiffening plate 12, width direction and short transverse relative to FPC connector 2;Work as extension When portion 122 is by external force along disassembly direction 4, limiting section 22 is separated with 123 phase of holding section, the quilt from FPC connector 2 of FPC 1 It takes out.
When FPC 1 is inserted into FPC connector 2, the head of extension 122 first contacts limiting section 22, the head of extension 122 Flexible deformation is generated downwards;After the head of extension 122 is inserted through limiting section 22, extension 122 restores flexible deformation, holding section 123 are sticked in limiting section 22;When needing to take out FPC 1 from FPC connector 2, apply along disassembly direction 4 to extension 122 External force, extension 122 generate flexible deformation, and holding section 123 is separated with 22 phase of limiting section.
In the present embodiment, as shown in figure 5, the top successively has disassembly 23 He of area along the length direction of shell 21 Bonding pad 24, disassembly area 23 are connected with the accommodating space, and the limiting section 22 in Fig. 1 and Fig. 2 is set to the bottom of bonding pad 24; When the extension 122 in Fig. 1 from disassembly area 24 by external force along disassembly direction 4 when, limiting section 22 and 123 phase of holding section are divided From FPC 1 is removed from FPC connector 2.
As shown in figure 5, disassembly area 23 has disassembly slot 231, the one end for dismantling slot 231 extends along the length direction of shell 21 To the left side at the top, bonding pad 24 is formed between the other end and the right side at the top.
Dismantle the presence of slot 231, on the one hand, so that when needing to take out FPC 1 from the FPC connector 2 in Fig. 1, energy It is enough that external force, FPC 1 easy to disassemble are applied to extension 122 by disassembly slot 231 more conveniently;On the other hand, pass through disassembly Slot 231 can observe the connection state of FPC 1 and FPC connector 2 in Fig. 1 more conveniently.
As shown in Fig. 1, Fig. 3 and Fig. 5, FPC connector 2 further includes spaced five gold of width direction along shell 21 Finger 25, five golden fingers 25 are arranged in the bottom and position in the accommodating space, and each golden finger 25 is for abutting In the bottom of ontology 11.FPC connector 2 is electrically connected to PCB 3 by five golden fingers 25.
In the present embodiment, as depicted in figs. 1 and 2, the bottom of the bonding pad 24 in Fig. 5 is additionally provided with five boss 241, Five boss 241 are arranged along the width direction interval of shell 21, and five boss 241 and five golden fingers 25 are relatively arranged on FPC 1 two sides, and each boss 241 is connected to interconnecting piece 121, and for being electrically connected FPC 1 with golden finger 25.
The presence of five boss 241 can guarantee that FPC 1 is reliably electrically connected with golden finger 25, to realize that FPC 1 can It is electrically connected by ground with PCB 3.
In the present embodiment, the length direction of the length direction of stiffening plate 12 and shell 21 is located along the same line, mends The strong width direction of plate 12 and the width direction of shell 21 are located along the same line.As shown in figure 4, the card slot and extension There is reserved portion 124, at least partly reserved portion 124 is located in the disassembly area 23 in Fig. 5 between 122 left side;When reserved portion 124 from disassembly external force of the area 23 by the disassembly direction 4 in Fig. 1 when, limiting section 22 is mutually separated with the card slot, FPC 1 from It is removed in FPC connector 2.
The FPC 1 in the FPC attachment device in present embodiment can be reliably connected at FPC connector 2, and group Assembly and disassembly are more convenient.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back Under the premise of from the principle and substance of the present invention, many changes and modifications may be made, but these are changed Protection scope of the present invention is each fallen with modification.
