Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a terminal cover device for electrical equipment.

[Conventional technology]

Conventional terminal cover devices of this type are shown in Figures 4 and 5.
A one-touch attachment method as shown in the figure has been proposed. In other words, in FIGS. 4 and 5, there are several 1s on the top surface (
The outside of the electrical equipment is equipped with 5 operation holes (5 in the figure).
In the main body), each of the operating holes 5 accommodates a connecting part 4 consisting of a terminal fitting 2 and a terminal screw 3, and the terminal screw 3 can be operated from the top surface 103 side of the outer cover 1 with a screwdriver. There is. Reference numeral 6 denotes a terminal cover that is attached to the upper surface 103 of the outer shell 1 and covers the operation hole 5 in order to prevent a person from inadvertently touching the connection part 4 and receiving an electric shock. This terminal cover 6 has tongue pieces 61 and 62 at both ends, and furthermore, tongue pieces 61 and 62 are provided at the portions corresponding to the operation holes 5 to measure the current conduction state and insulation state while the terminal cover 6 is attached to the outer cover 1. Test small holes 63 are provided. - Projections 101 and 102 are provided on the cover 1 to correspond to the tongue pieces 61 and 82 of the terminal cover 6, and the tongue pieces 61 and 62 of the terminal cover 6 are provided with protruding parts 101 and 102. Exit part 101,
By inserting the terminal cover 6 below the cover 102, the terminal cover 6 is fixedly held on the upper surface of the outer cover 1.

To attach the terminal cover 6 to such a device,
The terminal cover 6 is curved upward as shown by the dashed line in FIG.
102, then fit it in and install it. In addition, to remove this, insert the tip of the screwdriver 7 into the gap 104 between the terminal cover 6 and the outer cover 1, apply force to the terminal cover 6, and then bend and tension it as shown by the dashed line in the same way as before. The tongue piece 62 was pushed out from the protruding part 102 and removed.

[Problem to be Solved by the Invention 3] As explained above, when installing this structure, it is necessary to curve the terminal cover 6 upward in a convex manner and then fit it in. It's embarrassing. Furthermore, when removing the tongue piece 62, the moment the tongue piece 62 is pushed out from below the overhang part 102 by the screwdriver 7, the elasticity of the terminal cover 6 causes the terminal cover 6 to jump and hit the human body, or fall off. It has the problem of being lost.

The present invention has been made to solve the above-mentioned problems, and provides a terminal cover device that is easy to install and remove.

[Means for solving problems]

The terminal cover device for a single electric appliance according to the present invention has a terminal cover provided with a test elongated hole, an operating protrusion erected along the elongated hole, and tongue pieces that engage with the main body on both sides of the operating protrusion. It is something that

[Effect]

According to the terminal cover device for electrical equipment according to the present invention, when attaching or detaching the terminal cover, the operating tab can be pressed inward to narrow its width by utilizing the elasticity of the elongated hole. This can be done more easily.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 6 designates a terminal cover having a series of elongated holes 64 in the longitudinal direction through which several small holes 63 are communicated.
．． 62, operating protrusions 81, 82 are provided on both sides of the elongated hole B4. On the other hand, the engagement protrusion 101 of the outer shell 1
, 102 are also provided at the center corresponding to the tongue pieces 61, 82.

Next, the procedure for attaching and detaching the terminal cover in the above configuration will be explained. To attach the terminal cover 6, pinch the operating protrusions 81 and 82 with your fingers in the direction in which the width of the elongated hole 64 becomes narrower, that is, make the width I of the tongue piece B1.82 narrower than the width of the projecting parts 101 and 102. Then, look at the tongue piece 62 under the overhanging parts 101 and 102, and then release your finger to remove the overhanging part 1.
The tongue pieces 61 and 62 are fitted and held under 01 and 102 to complete the installation. To remove the terminal cover 6, pinch the operating protrusions 81 and 82 with your fingers in the same way as above, and press the tongue pieces B1.
The radius I of 62 is the width of the overhang 101.102! narrower,
After the terminal cover 6 is removed, it can be removed by lifting it up.

As described above, the terminal cover 6 can be attached and removed much more easily than in the conventional case. In addition, tools such as a screwdriver are not required for removal, and by setting the width of the elongated hole 64 appropriately, the width can be narrowed by pinching the operating protrusions 81 and 82 with your fingers. When deflected in the direction, both sides 65 and 66 of the elongated hole come into contact with each other and cannot be deflected any further.In other words, inadvertent excessive deformation can be prevented. There is no chance of breaking the terminal cover.

In the above embodiment, the operation protrusions 81 and 82 were provided on both sides of the elongated hole 64, but as shown in FIG.
The operating protrusion 81 may be provided only on one side of the elongated hole 64. Furthermore, if necessary, the shape of the elongated hole 64 may be changed to the shape shown in FIG. 3A, which is more flexible.

〔Effect of the invention〕

As described above, according to the present invention, the small test holes of the terminal cover 6 are made into elongated holes 64 to make the terminal cover 6 more flexible, and the operating protrusion 81 is provided on the side surface of the central portion.
82 so that the width of the tongue piece 61°B2 can be easily narrowed with a fingertip, it is possible to obtain a terminal cover device that is extremely easy to attach and detach.
