Description

  The present invention relates to an insertion plug device and an insertion plug detachment device that are inserted and connected to an outlet.

  After inserting and connecting an insertion plug provided at the tip of a power cord for supplying electric power such as a vacuum cleaner to an outlet and using it, when pulling out the insertion plug from the outlet, a relatively large force is required. It cannot be pulled out remotely.

  As the above-mentioned improvement measure, the plug described in Patent Document 1 is provided with a pickup lever via a pivotal support on the left and right sides of the plug body, and the plug is easily pulled out by pulling out the pickup lever. However, the plug cannot be removed by remote operation.

  In order to detach the plug by remote operation, if a tensile force is applied through the power cord, a large amount of force is required. Therefore, the lead wire of the power cord is torn off at the connection portion with the plug, or the plug There is a risk of disengagement.

  The insertion plug device described in Patent Document 2 removes a locking member that locks a pre-compressed spring pressure by pulling a power cord connected to the insertion plug from a remote location, thereby removing the plug body from the outlet. It can be pulled out.

  However, the insertion plug device has a complicated structure because it requires many parts. In addition, since the plug is disconnected from the outlet when the power cord is pulled, the plug apparatus is disconnected from the outlet even when the power cord is accidentally pulled during work such as a vacuum cleaner. It may be necessary to connect the plug device to the outlet again, which may be troublesome.

The insertion plug body 2 has a connection terminal 24 at the tip thereof, and a power cord 15 is provided on the opposite side of the connection terminal 24. Two pairs of pivot projections 14a and 14b are formed on both side surfaces of the insertion plug body 2. Is installed. The release levers 3a and 3b are pivotally attached to the pivoting projections 14a and 14b of the insertion plug body 2, and springs that urge the protruding portions of the release levers 3a and 3b in a direction to release the insertion plug body 2. The bodies 8a and 8b are interposed.

  A release lever locking member 10 for locking or releasing the release levers 3a and 3b rotated against the spring bodies 8a and 8b engages with the engaging protrusions 6a and 6b of the release levers 3a and 3b. The stopper portion 11 and a catcher portion 12 that receives movement in a direction perpendicular to the longitudinal direction of the power cord 15 are configured, and are pivotally attached to the insertion plug body 2 via a flexible portion 13 so as to be swingable.

  In the above configuration, the plug-in device 1 in a state in which the release levers 3a and 3b are rotated against the spring bodies 8a and 8b and the engaging protrusions 6a and 6b and the engaging portion 11 are fitted to the outlet 16 is provided. FIG. 3 shows a plan view of the inserted state and FIG. 4 shows a side view thereof.

  In a situation where the plug apparatus 1 is inserted into the outlet 16, the power cord 15 connected from the plug body 2 is moved in a direction perpendicular to the longitudinal direction, and the release lever locking member 10 is swung via the catcher section 12. FIG. 5 shows a plan view of a situation in which the engaging portion 11 fitted to the engaging protrusions 6a and 6b of the release levers 3a and 3b is released and the plug-in plug device 1 is detached from the outlet 16. The side view is shown in FIG.

  According to the present embodiment, in the plug-in device 1, the pressing parts 5 a and 5 b of the pair of release levers 3 a and 3 b are pinched and locked by the locking part 11 of the release lever locking member 10 and then inserted into the outlet 16. For example, the plug device 1 is detached from the outlet 16 by moving the power cord 15 connected to the plug device 1 in a direction perpendicular to the longitudinal direction and swinging the release lever locking member 10 via the catcher portion 12. Can be made.

  FIG. 7 is a perspective view of the insertion plug 23 via the insertion plug removal device 21 according to the second embodiment of the present invention, and FIG. 8 is an exploded perspective view of the insertion plug 23 similarly via the insertion plug removal device 21. Two pairs of pivot projections 14 a and 14 b are provided on both side surfaces of the plug-in holding member 22. The release levers 3a and 3b are pivotally attached to the pivot protrusions 14a and 14b of the insertion plug holding member 22, and the protruding portions of the release levers 3a and 3b are connected to the insertion plug 23 via the insertion plug removal device 21. Spring bodies 8a and 8b for biasing in the direction of detachment are interposed.

  A release lever locking member 10 for locking or releasing the release levers 3a and 3b rotated against the spring bodies 8a and 8b engages with the engaging protrusions 6a and 6b of the release levers 3a and 3b. The stopper portion 11 and the catcher portion 12 that receives movement in the direction perpendicular to the longitudinal direction of the power cord 15 are configured, and are pivotally attached to the insertion plug holding member 22 via the flexible portion 13 so as to be swingable.

  In the above-described configuration, the release levers 3a and 3b are rotated against the spring bodies 8a and 8b, and the insertion plug holding member 22 is engaged with the engagement protrusions 6a and 6b and the locking portion 11 fitted. In a situation where the plug 23 is inserted into the outlet 16, the power cord 15 connected from the plug 23 is moved in a direction perpendicular to the longitudinal direction, and the release lever locking member 10 is swung through the catcher portion 12. Then, the engaging portion 11 fitted to the engaging protrusions 6a and 6b of the release levers 3a and 3b is released, and the plug 23 via the plug plug removing device 21 is detached from the outlet 16.

  According to the present embodiment, in the insertion plug 23 via the insertion plug detaching device 21 as in the first embodiment, the engaging portions of the release lever locking member 10 are pinched by pinching the pressing portions 5a and 5b of the pair of release levers 3a and 3b. If it is inserted into the outlet 16 after being locked by the stopper 11, the power cord 15 connected to the insertion plug 23 via the insertion plug detaching device 21 is moved in a direction perpendicular to the longitudinal direction and the release lever is connected via the catcher 12. By swinging the locking member 10, the insertion plug 23 via the insertion plug removal device 21 can be detached from the outlet 16.

  When working with a vacuum cleaner, etc. in a large area, it is often impossible to cover a wide working range simply by connecting the plug to a single outlet, and it is necessary to replace the plug with multiple outlets. Is done. With conventional plugs, in order to remove the plug inserted into the outlet, it is necessary not only to return to the outlet position but also to bend in some situations.

  The insertion plug device of the present invention or the insertion plug via the insertion plug detachment device does not need to return to the outlet position one by one, and it is possible to detach the insertion plug from the outlet remotely. It can be expected to contribute to reducing fatigue because it is not necessary to bend.
