A circuit element protection apparatus applied to a signal input terminal, the circuit element protection apparatus includes a slave processing unit, a main processing unit, a first soft start unit and a second soft start unit. The first soft start unit receives a signal from the signal input terminal, and is used for noise filtering on the signal and delayed a transmission of the signal to the slave processing unit. The second soft start unit receives the signal from the signal input terminal, and is used for noise filtering on the signal and delayed the transmission of the signal to the main processing unit. The present disclosure further includes a protection method for circuit elements.

A shield connector includes: a housing that holds a terminal; a seal member; a holder coupled to the housing along an axial direction of the housing to support the seal member; and a shell, in which the shell has a protruding portion protruding inward from an inner wall surface of the shell, the holder has an engagement piece extending along the axial direction, and is locked by the shell by engaging the engagement piece with the protruding portion, the protruding portion has a locking surface that locks the engagement piece, and the locking surface is a surface facing an insertion direction in which the holder is inserted into the shell, and is an inclined surface toward the insertion direction as the locking surface extends toward a tip of the protruding portion in a protruding direction.

Junction boxes are disclosed relating to commercial and residential wiring that include a container and multiple push in locking electrical connectors. The push in locking electrical connectors are arranged facing the exterior of the box such that the box is operable without being opened and such that the individual conductors of multiconductor wires may be conveniently wired to separate sets of push in locking electrical connectors electrically joining the multiconductor wires.

A connector assembly includes at least one elongated inner signal contact having a first connection portion. The first connection portion includes a tube-like main section and a funnel-shaped end section. The first connection portion further includes an insulating element. The insulating element defines at least one elongated cavity designed to accommodate the elongated inner signal contact. A maximum outer cross-sectional dimension of the funnel-shaped end section is greater than a minimum cross-sectional dimension of the elongated cavity.

A connector includes a housing including a terminal accommodation chamber, a terminal fitting including a locking hole and to be inserted into the terminal accommodation chamber from behind the housing, and a locking lance for retaining the terminal fitting inserted into the terminal accommodation chamber. The locking lance is cantilevered forward and includes a body portion resiliently displaceable in a direction intersecting an insertion direction of the terminal fitting and a projection projecting from the body portion toward the terminal fitting and configured to enter the locking hole when the terminal fitting is inserted into the terminal accommodation chamber. A width of the projection is smaller than that of the locking hole. A maximum width of the body portion is larger than the width of the projection. A part of the body portion connected to the projection is formed with a guiding portion gradually reduced in width toward the projection.

A power tool including a housing that has a battery pack receiving portion configured to receive an interface of a battery pack, device contacts extending from the housing and configured to mechanically and electrically engage with the battery pack, and a latching mechanism supported by the housing and including an actuator and a latch member configured to selectively engage the interface of the battery pack. The actuator is pivotable to operatively pivot the latch member.
