The present invention relates to a touch detection device, an electronic apparatus and a touch detection method. Each frame of touch related data corresponding to n*m capacitive nodes is obtained by producing n*m coupled signals from encoding operations and subjecting the n*m coupled signals to multiple access accumulation process, common mode suppression process, ADC process and decoding processes. Additionally, touch location information of the n*m capacitive nodes is obtained by acquiring two consecutive frames of touch related data and performing a subtraction operation between the two consecutive frames of touch related data. Therefore, relatively high touch sensing sensitivity is achievable. Before the subtraction operation, common-mode analog voltage amounts subtracted in the common mode suppression process may be not added back for each single frame of touch related data obtained from decoding process. This avoids introduction of errors, as well as a larger circuitry area and increased power consumption.

An electrical connector includes a main body portion having a receiving passage adapted to receive a plate-type plug inserted in an insertion direction, and a locking protrusion formed on the main body portion and protruding toward the receiving passage. The locking protrusion has a connection portion adapted to connect a top portion of the locking protrusion with the main body portion downstream in the insertion direction.

Electrical connector

A receptacle terminal includes a base portion having a plate shape extending in a transverse direction and a longitudinal direction and a plurality of pairs of elastic arms arranged in sequence and spaced apart from each other in the longitudinal direction. Each of the elastic arms has a contact portion contacting a plug terminal inserted into the receptacle terminal. A distance from the contact portions of a middle pair of elastic arms to the base portion is less than a distance from the contact portions of another two pairs of elastic arms to the base portion.

Receptacle terminal

A sensor assembly comprises a housing, a pressure interface, a piezoelectric sensor, a mechanical interface, and an electrical interface. The pressure interface is disposed on the housing and communicates with a pressure transmission tube. The piezoelectric sensor is disposed in the housing and senses a pressure input at the pressure interface. The mechanical interface is disposed at a first side of the housing and detachably engages a mounting mechanism. The electrical interface is disposed at a second side of the housing opposite to the first side.
