[0033] The terminal unit according to the present embodiment is equipped with, for example, figure 2 Embedded wiring device 10 is shown. In the following description, the up-down direction, front-back direction, and left-right direction are defined according to the state in which the wiring device 10 is attached to the wall (in figure 2 , the up-down direction is vertical, the lower-left side is forward and the upper-left side is left). However, these definitions are not intended to limit the orientation in which the terminal unit may be used.

[0034] Such as figure 2 The illustrated wiring device 10 includes a device housing 11 made of synthetic resin. The device housing 11 includes a rectangular box-shaped body 110 having a front opening, and a cover 120 combined with the body 110 to cover the opening of the body 110 .

[0035] A pair of storage chambers 111 arranged side by side in a lateral direction (left-right direction) are formed in each longitudinal (vertical)...

[0087] The terminal unit 1 of the present embodiment is fitted to an outlet as a wiring device. The terminal unit 1 of this embodiment differs from the terminal unit 1 of the first embodiment in that Figure 8 Protrusions 213 are formed in the clamping tab 21 of the illustrated end plate 2 .

[0088]The protrusion 213 is formed on a clamping surface 214 which is one thickness direction surface (front surface) of the clamping piece 21 . The protrusions 213 are arranged between the insertion grooves 211 of the clamping pieces 21, and have a circular shape as seen in plan view. The protrusion 213 protrudes forward from the clamping surface 214 . The protruding dimension of the protrusion 213 is set to be greater than the thickness of the connecting piece 33 of the lock spring 3 . In other words, the height of the protrusion 213 from the clamping surface 214 is set to be greater than the height of the connecting piece 33 of the lock spring 3 from the clamping surface 214 .

Abstract

PROBLEM TO BE SOLVED: To provide a terminal device in which operation of a release lever is stabilized and locking of an electric wire can be reliably released when the release lever is operated.SOLUTION: A release lever 4 comprises: an operation part 40 exposed to the outside of a body 11; a shaft part 41 serving as the center of rotation accompanying the operation of the operation part 40; and an action part 42 being in contact with a lock piece 31. The shaft part 41 is supported by the body 11 at fixed positions on both sides of a lock spring 3. The action part 42 is in contact with both ends in a lateral direction of the lock piece 31 and presses the both ends in the lateral direction of the lock piece 31 in response to the operation of the operation part 40.

Description

technical field [0001] The present invention relates to a terminal unit for simultaneously electrically connecting and mechanically clamping electric wires inserted from an insertion hole of a device housing, and a wiring device including the terminal unit. Background technique [0002] To simplify the work of connecting wires in wiring devices such as receptacles and switches, quick-connect terminal units are routinely available which simultaneously electrically connect and mechanically clamp the wires inserted through the insertion holes in the housing of the device , to be able to connect wires without using screws. [0003] As an example of this type of terminal unit, there is known a terminal unit including a lock spring for locking an electric wire inserted through an insertion hole of the device housing and preventing When a tool such as a screwdriver is manipulated through a manipulation hole defined in the device casing, the unlocking button is used to unlock the w...
