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 connection terminal comprises a receptacle portion, a wire crimping portion, and a connection portion. The receptacle portion includes a latching elastic sheet disposed at a rear end of the receptacle portion. The wire crimping portion includes a conductor crimping portion adapted to be crimped onto a conductor of the wire. The connection portion is connected between the rear end of the receptacle portion and the wire crimping portion and includes a first connection portion and a second connection portion. The conductor crimping portion and the latching elastic sheet are disposed between the first connection portion and the second connection portion and opposite to each other in the longitudinal direction. The first connection portion has a first bent portion and the second connection portion has a second bent portion. The first bent portion and the second bent portion each protrude in a height direction.

Connection terminal

A connection terminal comprises a receptacle part, a crimping part, and a connection part connected between the receptacle part and the crimping part. The crimping part includes a conductor crimping part adapted to be crimped on a conductor of a wire and an outer layer crimping part adapted to be crimped on an outer layer of the wire. The conductor crimping part includes a first conductor crimping part and a second conductor crimping part which are spaced from each other by an interval in a lateral direction perpendicular to the longitudinal direction. The receptacle part includes an elastic latch adapted to lock a plug inserted into the receptacle part and located at a rear end of the receptacle part close to the crimping part. The elastic latch is positioned between the first conductor crimping part and the second conductor crimping part in the lateral direction.

A buck-boost converter includes a buck-boost voltage converter circuit, an error controller and a buck-boost mode controller. The buck-boost voltage converter includes switches. The error controller is configured to provide a control signal based on a difference between an output voltage of the buck-boost voltage converter circuit and a reference voltage. The buck-boost mode controller determines switching duty cycles based on the control signal having at least three conditions: when DC is beyond a threshold value, apply one of buck regulation control and boost regulation control, where DC is a value of the control signal; when DC is not beyond and not substantially equal to the threshold value, apply the other of the buck regulation control and the boost regulation control; and when DC is substantially equal to the threshold value, apply buck-boost regulation control. The output voltage is regulated by the switching duty cycles.
