Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the correlation technique, electronic equipment such as cell-phone is last to be provided with the fingerprint identification module usually for gather user's fingerprint information. When the fingerprint identification module is installed, two installation modes are generally included, one mode is that the fingerprint identification module is assembled on the middle frame body of the electronic equipment under the condition that the middle frame body is externally displayed, and the rear shell is buckled with the middle frame body; the other type is that the middle frame body of the electronic equipment is in a hidden state, namely the middle frame body is coated by the rear shell, and the fingerprint identification module is assembled on the rear shell.

Generally, fingerprint identification module and electronic equipment's power key be assembled between/be connected, use as multi-functional key, can enough realize the fingerprint collection function, can realize the switch-on/off function through user's operation again. However, the assembly of fingerprint identification module and power key is extremely complicated, if the skew appears in the mounted position of fingerprint identification module when the assembly, can lead to the position of fingerprint identification module and power key to fail accurate the correspondence, the dislocation condition appears, causes the unable normal use of electronic equipment's side button, can not realize the switch machine function.

In an example, as shown in fig. 1, a middle frame body 1 ' of an electronic device is in an explicit state, a fingerprint identification module 2 ' is assembled on the middle frame body 1 ', an accommodating space 11 ' with an opening is provided at a side of the middle frame body 1 ' of the electronic device, and the fingerprint identification module 2 ' is clamped into the accommodating space 11 ' from the outside of the electronic device, i.e., is mounted on the middle frame body 1 ' from the top to the bottom above the middle frame body 1 '. The fingerprint identification module 2 ' is fixed in the accommodating space 11 ' through the special-shaped steel sheet 3 '.
