In 222 on the first connecting plate, and it is located at test conduction portion outside 222 on the first pressing plate 225, support plate 223 and the first connecting plate
Side, forming an assembling entirety will when needing to crimp using the first FPC plate 220 with the display screen screen semi-finished product of corresponding specification
The assembling is mounted as a whole on the second briquetting 242 can (dismountable mode, such as using bolt by the first connecting plate 222 and the
The connection of two briquettings 242), it connects fastly, Quick Release, it is easy to operate.
Embodiment two
As shown in Figures 3 to 5, the gauge head component be probe 231 connect with the 2nd FPC plate 230 be connected structural member, second
FPC plate 230 is fixed on the second briquetting 242 by connection component, which includes the second connecting plate 232 being connected and
Two pressing plates 233, the second connecting plate 232 are connect with the second briquetting 242, and the 2nd FPC plate 230 is placed in the second connecting plate 232 and second
Between pressing plate 233, the second pressing plate 233 is connected with the second positioning column 234 of the 2nd FPC plate 230 of positioning, and probe 231 passes through the
Two pressing plates 233 are connect with the 2nd FPC plate 230.The position of the 2nd FPC plate 230 can be limited, using the second positioning column 234 so as to standard
Really crimped with display screen screen semi-finished product；Second pressing plate 233 can generate movement in crimping to avoid the 2nd FPC plate 230, it is ensured that
The accuracy of crimping.
In addition, the second pressing plate 233 of the embodiment is also connected with the second insulation cushion 235, the end of probe 231 is pierced by
Two insulation cushions 235.It can avoid display screen screen semi-finished product using the second insulation cushion 235 and generate damage during crimping.
As it can be seen that only the 2nd FPC plate 230 need to be fixed between the second pressing plate 233 and the second connecting plate 232, and make probe
231 are located at the outside of the second pressing plate 233 and the second connecting plate 232, form an assembling entirety, are needing using the 2nd FPC plate
230 with the display screen screen semi-finished product of corresponding specification when crimping, which is mounted as a whole on can be (removable on the second briquetting 242
Second connecting plate 232 is such as connect by the mode unloaded using bolt with the second briquetting 242), it connects fastly, Quick Release, it is easy to operate.
The technical principle of the invention is described above in combination with a specific embodiment.These descriptions are intended merely to explain of the invention
Principle, and shall not be construed in any way as a limitation of the scope of protection of the invention.Based on the explanation herein, the technology of this field
