Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an outlet having a retaining structure for a blade.

[Prior Art] Generally, this type of outlet includes a blade receiving spring for receiving a plug blade of a plug, a terminal plate electrically connected to the blade receiving spring, and a contact piece formed on the terminal plate. It mainly comprises a locking spring for elastically contacting the conductor of the inserted electric wire to make contact therewith, and a release button for pressing the locking spring to release the contact between the contact piece and the conductor.

[Problem to be Solved by the Invention] In assembling such an outlet, a terminal plate is disposed in a body, and then a locking spring is incorporated. However, there is a problem that it is difficult to insert the locking spring due to the presence of the terminal plate.

The present invention is provided in view of the above points,
An outlet intended to improve the assemblability of a locking spring is provided.

[Means for Solving the Problems] In the present invention, a guide piece for guiding the insertion of the locking spring when the locking spring is inserted and arranged is bent on the terminal plate.

[Operation] The guide piece guides the insertion of the lock spring when the lock spring is inserted and arranged.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the entire outlet, in which a body 1 having an open upper surface is provided with a terminal plate housing 3 via a partition wall 2. Blade receiving springs 6 are mounted and fixed on connecting pieces 5 formed at both ends of a conductive terminal plate 4 housed in the terminal plate housing 3. The blade receiving spring 6 includes a pair of spring pieces 6a.
The one spring piece 6a is formed in an arc shape as shown in FIG. The other spring piece 6a is formed in a substantially rectangular shape, and on the inner surface thereof, the plug blade of the plug inserted into the blade receiving spring 6 is rotated to insert and lock into a hole formed in the blade. A projection 7 is provided to prevent the blade from coming off.

The central portion of the terminal plate 4 is integrally formed with the U-shaped pieces 8 facing each other, and as shown in FIG. 2, the contact pieces 9 are integrally formed from the lower edges on both sides of the upper piece 8a. . As shown in FIG. 4 (d), the contact piece 9 is to be in contact with and connected to the conductor of the electric wire inserted through the wire insertion hole 10 on the lower surface of the body 1, and a chain arranged on the side of the contact piece 9 When the lock spring 11 elastically contacts the conductor of the electric wire to the contact piece 9 side, the conductor is contact-connected to the contact piece 9. A release button 12 for pressing the locking spring 11 to release the contact between the contact piece 9 and the conductor of the electric wire is disposed in the body 1 so as to bridge the two locking springs 11. A hole 13 is formed in the lower surface of the body 1 to insert the tip of the driver so as to press the release button 12.

Here, the locking spring 11 is inserted and arranged from above after the terminal plate 4 is placed in the body 1.
As shown in FIGS. 2 and 3, a guide piece 14 is formed by bending the upper end of the upper piece 8a outward so that the upper end 8a of the U-shaped piece 8 of the terminal plate 4 does not catch on the upper end of the upper piece 8a. Is formed. Therefore, the locking spring 11 can be inserted and arranged in the body 1 so as to be guided by the guide piece 14 so as not to be caught.

The cover 15 covering the opening surface of the body 1 has a blade receiving spring 6
Two sets of arc-shaped plug blade insertion holes 16 are formed in correspondence with the above.
The ribs 17 and 1 are provided on both sides of the cover 15 and the body 1, respectively.
8 is protruded, and the rib 18 of the body 1 has a concave portion 18a on the lower surface.
Is recessed. A bracket-shaped connecting piece 23 is integrally suspended from the side piece 22 of the metal mounting frame 21. The connecting piece 23 is fitted into the ribs 17 and 18 of the cover 15 and the body 1, and
By crimping the lower side of the cover 18 into the recess 18a of the rib 18,
And the body 1 are combined.

The mounting frame 21 is provided with a cover 15 as shown in FIGS.
It has an opening 24 for exposing the front surface of the device, and mounting holes 25 for screw insertion for mounting to a box embedded in the wall surface are provided on the upper and lower sides. Further, a screw hole 26 for mounting the plate frame is formed.

As shown in FIGS. 6 and 7, a tongue piece 31 is integrally formed so as to extend upward from the edge of the connection piece 5 of the terminal plate 4. As shown in FIGS. A rib 32 is suspended from the ceiling surface of the cover 15 at a position corresponding to the tongue piece 31, and a projection 34 fitted into a recess 33 recessed below the rib 32 forms a partition wall of the body 1. 2 is formed on the upper surface. When the cover 15 is covered on the body 1, the rib 32 is located close to the tongue piece 31 of the terminal plate 4 to prevent the terminal plate 4 from rising. That is, when trying to pull out the plug blade of the plug, the blade receiving spring 6 rises when the plug blade is not pulled out by the projection 7 as described above, but the tongue piece 31 hits the lower surface of the rib 32, The terminal board 4 can be prevented from rising.

[Effects of the Invention] As described above, in the present invention, the guide piece for guiding the insertion of the locking spring when the locking spring is inserted and arranged is bent on the terminal plate. The guide guides the insertion of the lock spring when the spring is inserted and arranged. Therefore, the insertability of the lock spring is improved, and the assemblability is improved.
Also, the bent guide piece has an effect of increasing the strength of the terminal plate.
