The connector includes a coupling member configured to, when the first lead portion is inserted into the channel, mechanically engage the coupling recess to secure the first lead portion to the second lead portion at least in an axial direction relative to the longitudinal axis.

According to examples, a memory module with module rows of conductive contacts can enable multiple memory channels to be connected to the same memory module. In one example, a memory module includes a printed circuit board (PCB) having a first face, a second face, and an edge to be received by a connector. The memory module includes a plurality of memory chips on at least one of the first and second faces of the PCB. The memory module includes two or more rows of conductive contacts on each of the first and second faces of the PCB, the two rows including a first row of conductive contacts proximate to the edge of the PCB to be received by the connector, and a second row of conductive contacts between the first row and a second edge of the PCB opposite to the first edge.

A state detection device in an audio interface includes: a first voltage detection circuit, a second voltage detection circuit and a state determination circuit. The first voltage detection circuit is coupled to a first contact and a second contact of an audio jack socket, for detecting a voltage across the first contact and the second contact to generate a first detection value. The second voltage detection circuit is coupled to a third contact of the audio jack socket, for detecting a voltage on the third contact to generate a second detection value. The state determination circuit is coupled to the first voltage detection circuit and the second voltage detection circuit, for determining a water ingress state of the audio jack socket according to the first detection value, and a connector type of an audio plug that is inserted into the audio jack socket according to the second detection value.

An electrical connector includes an electrically conductive contact element (122) and a support (70). The contact element (122) is supported by an intermediate element (120) made of an elastically deformable material and connected to the support (70). An electrical connection assembly including a connector of the type is also described.

A connector for sealably engaging contacts therein and permitting reliable disengagement thereof includes a first unit having one or more elongated shafts. Each elongated shaft includes at least one first contact. The connector further includes a second unit having a body with one or more channels therein. Each channel includes at least one second contact. Each channel is configured to receive at least a portion of one of the elongated shafts therein to permit electrical connection of the one or more first contacts to the respective one or more second contacts. The second unit further includes an axial slit extending radially outwardly from each channel toward an outer surface of the body of the second unit. Each slit of the second unit is a circumferentially discontinuous portion of the channel configured to prevent the second unit from forming a constrictive belt around the one or more elongated shafts therein.
