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 for this tumor 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 shield l 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, respectively, to measure the conduction state and insulation state while the terminal cover 6 is attached to the outer cover 1. Test small holes 63 are provided. - The tongue piece 1 is provided with a projecting portion 101.102 corresponding to the tongue piece 61.02 of the terminal cover 6, and the tongue piece 61.62 of the terminal cover 6 is provided with a projecting part 101.102. 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. 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 bend it as shown by the dashed-dotted line as before. The tongue piece 62 was pushed out from the projecting part 102 and removed.

[Problem that the invention seeks to solve]

As described above, when installing this structure, it is necessary to curve the terminal cover 6 upward in a convex manner and then fit it in. This operation is difficult and difficult to fit. Furthermore, when removing the terminal cover 6, the moment the tongue piece 82 is pushed out from below the overhanging part 102 with 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 and be lost. There is a problem with this.

The invention of B was made to solve the above-mentioned problems and provides a terminal cover device that is easy to install and remove.

[Means for solving problems]

In the terminal cover device for electrical equipment according to the present invention, an engaging protrusion having an umbrella-shaped projecting portion is provided on the upper surface of the main body on which the terminal cover is fixed, and is arranged in line with a connection terminal operation hole, and the engaging protrusion and the engaging protrusion are operated. A terminal cover having a test elongated hole corresponding to both of the holes is fixed by fitting the elongated hole into the above-mentioned engagement protrusion (as well as rubbing it and engaging with the above-mentioned elongated hole to make its width dimension variable). It is equipped with an operation knob to

[Effect]

According to the terminal cover device for electrical equipment according to the present invention, there is no need to provide a tongue piece on the terminal cover as in the conventional case, and when removing the terminal cover, the elongated hole can be pushed horizontally with the operation knob. This allows the cover to be easily removed without bending it.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. 6
8 is a terminal cover having a series of elongated holes 64 in the longitudinal direction, and 8 is an umbrella-shaped terminal cover that fits into this elongated hole 64 and has an overhang portion 105 and 106 having a width L2 wider than the width L of the elongated hole 64. It is an engaging protrusion, and is arranged on the upper surface 10 of the outer shell 1 in line with the operation hole 5 in the center.
A pair of protrusions are provided at 3. Further, an operating knob housing portion 65 is formed approximately in the center of the elongated hole 64, and the operating knob 7 consisting of a small diameter portion 71, a large diameter portion 72, and a collar portion 73 is housed in the housing portion. An operation knob storage recess 9 is provided on the outer upper surface corresponding to the storage section 65.

Next, the procedure for attaching and detaching the terminal cover 6 in the above configuration will be explained. First, when attaching the terminal cover 6, press the terminal cover 6 against the collar portion 73 so that the terminal cover 6 engages with the large diameter portion 72 of the operating knob 7, as shown in FIG. 3A. At this time, the elongated hole 64 is expanded by the large diameter portion 72 to be wider than the width L2 of the protruding portions 105 and 106 of the engaging protrusion 8 as shown in FIG. 2, and the operating knob 7 is held integrally by its own elasticity. do. After connecting the operating knob 7 and the terminal cover 6 in this way, hold the operating knob 7 and insert the elongated hole 64 of the terminal cover 6 into the operating hole 5 and the engaging protrusion 8 as shown in the opening in FIG. Terminal cover 6 is placed on the top surface 103 of outer cover 1
is placed in place, and then the operating knob 7 is pushed toward the storage recess 9 as shown in Figure 3, and the engagement between the terminal cover 6 and the large diameter portion 72 of the operating knob 7 is released. At this time, the elongated hole 64 of the terminal cover 6 returns to its original width L1, which is narrower than the width L2 of the overhanging portions 105 and 106, and the inner edge of the terminal cover 6 is locked by the overhanging portions 105 and 106, and the terminal cover 6 is removed. Write 1
It will be installed on the top surface of the

Next, to remove the terminal cover 6, pull the operating knob 7 from the attached state shown in FIG. , the elongated hole 64 is expanded and the overhanging portions 105 and 106 of the engaging protrusion 8 are formed.
Since the engagement between the inner edge of the elongated hole 64 and the inner edge of the elongated hole 64 is released, the third rll
If the operating knob 7 is further pulled up as shown in A, the terminal cover 6 can be removed.

〔Effect of the invention〕

As described above, according to the present invention, the elongated hole 6 of the terminal cover 6
By providing the operation knob 7 that changes the width dimension of the terminal cover 4, the terminal cover 6 can be attached and detached extremely easily.
It has the advantage of not requiring special attachment/detachment tools such as a screwdriver.
