When the connector 55 and 57 are passed over the locking projection 74 provided inside the connector, the connectors 55 and 57 are completely fitted and connected and fixed so as to be able to conduct electricity.

On the other hand, the indicator 2 remains fixed upright on the upper case 52. However, by rotating the lever member 61 as described above, the operating portion 62 comes to cover the indicator 2 from above. Since the positions of the indicator 2 and the insertion hole 3 are set to correspond to each other, by rotating the lever member 61, the indicator 2 is shown as a dotted line in FIG. 2 and as shown in a sectional structure in FIG. Penetrates through the insertion hole 3.

By the way, in the case of this embodiment, the operation unit 62
Is about 2 mm, but the stroke between the completely fixed state and the incompletely fixed state is about 5 mm. Therefore, as described above, the lever member 61 is rotated, the indicator 2 penetrates the insertion hole 3 as shown in an enlarged view in FIG. , The indicator 2 does not enter the insertion hole 3.

According to this configuration, the operator visually checks whether or not the insertion hole 3 is closed, and thereby determines whether or not the lever member 61 is locked, in other words, whether the connector 5
It can be confirmed whether or not 5, 57 are completely fitted.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 4 is a cross-sectional view showing the shapes of the indicator and the insertion hole. The main difference between this embodiment and the first embodiment is that the structures of the indicator and the insertion hole are changed. Therefore, members other than the indicator and the insertion hole may be the same as those in the first embodiment, and the same members are denoted by the same reference numerals and description thereof will be omitted.

In this embodiment, a slit 5a is formed in the indicator 5 in the vertical direction, and the insertion hole 6 formed in the operation part 62 has a small width at one end (the end which becomes the upper end at the time of fitting).
The other end (the end that becomes the lower end at the time of fitting) is formed in a tapered shape that widens downward and is large. The width of the other end of the insertion hole 6 is formed slightly smaller than the width of the indicator 5.

According to the configuration of the indicator 5 and the insertion hole 6 as described above, when the lever member 61 is rotated in the direction of arrow A and the operation part 62 approaches the upper part of the indicator 5, it is shown by an imaginary line in FIG. The upper end of the indicator 5 is inserted into the lower end of the insertion hole 6 as described above. Then, when the rotation of the lever member 61 is continued and the lever member 61 is locked to the locking protrusion 74,
The slit 5 a is narrowed by the action of the tapered surface, and the integrated top of the indicator 5 closes the insertion hole 6.

Therefore, even when the thickness of the lever member 61 does not greatly differ from the stroke between the completely fixed state and the incompletely fixed state, the indicator 5 can be in the fully fixed state or the incompletely fixed state in the insertion hole 3. The completely fixed state can be easily recognized by visually observing the integrated state having no slit at the end of the light emitting element.

As described above, even in this embodiment, the operator can easily recognize whether or not the lever member 61 is completely fixed by visually checking whether or not the insertion hole 6 is closed by the indicator 5. It can be confirmed whether or not the connectors 55 and 57 are completely fitted.

In the first and second embodiments, when the connectors 55 and 57 are completely fitted and the lever member is completely fixed, the indicators 2 and 5 close the insertion holes 3 and 6, and Although the upper end is formed so as to be flush with the operation unit 62, the indicators 2 and 5 are inserted through the insertion holes 3 and 6.
May be formed so as to protrude from the insertion holes 3 and 6 on the contrary.

Further, the upper surfaces of the indicators 2 and 5 may be colored differently from the operation unit 62. According to this configuration, by visually checking the presence or absence of the color, the fixed state of the lever member can be easily recognized, and the fitted state of the connectors 55 and 57 can be more easily confirmed. Further, the indicators 3 and 5 are not limited to a prismatic shape, and may be formed in a cylindrical shape.

Next, a third embodiment of the present invention will be described with reference to FIGS.
An embodiment will be described. FIG. 5 is an exploded perspective view showing a configuration of the electric connection box, FIG. 6 is a side view showing a locked state of the lever member,

The main difference between the present embodiment and each of the above embodiments is that the structures of the indicator and the insertion hole are changed. Therefore, members other than the indicator and the insertion hole may be the same as those in the above embodiments, and the same members are denoted by the same reference numerals and description thereof will be omitted.

In this embodiment, the indicator 11
Has a slit 11a formed in the vertical direction and an umbrella-shaped locking projection 11b formed at the top. The upper end of the insertion hole 12 is formed in a large locking recess 12a.

As described above, when the lever 61 is rotated in the direction of arrow A and the operation part 62 approaches the upper part of the indicator 11, the top of the locking projection 11b of the indicator 11 enters the insertion hole 12. When the rotation is further continued from this state, the width of the indicator 11 is reduced by the action of the slit 11a, and the indicator 11 passes through the insertion hole 12.

Then, as described above, the connectors 55, 57
When the lever member 61 is completely fixed as described above, the locking projection 11b enters the locking recess 12a and elastically opens as shown by the solid line, and the locking projection 11b is inserted into the locking recess 12a. Locked.

On the other hand, when unlocking is performed, the indicator 1 is pinched by a finger or a tip of a driver or the like.
When 1 is urged in the center direction, the width dimension is narrowed by the interval of the slits 11 a, and comes out of the insertion hole 12.

Are double-locked, and the reliability of the electric junction box is significantly improved.

In this embodiment, the operation unit 62
Is 2 mm, and the stroke difference between the completely fixed state and the incompletely fixed state is 5 mm, so that the locking projection 11b does not appear in the locking recess 12a in the incompletely fixed state. Therefore, the operator can easily confirm the completely fixed state and the incompletely fixed state of the lever member 61 by the presence or absence of the locking projections 11b, in other words, by visual observation, and the fitting mistake of the connectors 55 and 57 due to carelessness. Can be prevented.

Next, a fourth embodiment of the present invention will be described with reference to FIG. FIG. 4 is a cross-sectional view showing the shapes of the indicator and the insertion hole.

On the other hand, the insertion hole 3 formed in the operation unit 62 has the same shape as in the first embodiment. The small width portion of the locking projection 15 b is set slightly smaller than the width of the insertion hole 3.

According to the above-described configuration of the indicator 15 and the insertion hole 3, when the lever member 61 is rotated in the direction of arrow A and the operation portion 62 approaches the upper portion of the indicator 15, the small width portion of the locking projection 15b, that is, the upper end is formed. The part enters the lower end of the insertion hole 3. Then, when the rotation of the lever member 61 is continued, the lateral width of the indicator 15 is reduced corresponding to the width of the slit 15a, and penetrates through the insertion hole 3.

At the time when the lever member 61 is locked by the locking projection 74, the locking projection 15b provided at the tip of the indicator 15 protrudes above the operating portion 62, and the narrowed slit 15a opens to open the locking projection. 15b is spread on the operation unit 62. Therefore, when the connectors 55 and 57 are completely fitted, the lever operating portion 61 is locked by the locking protrusions 62a and 74 as described above, and the locking protrusion 15b is locked by the operating portion 62. That is, in the present embodiment, the lever operation portion 61 is double-locked, and the reliability of the electric connection box is significantly improved.

Further, even when the thickness of the lever member 61 does not largely differ from the stroke between the completely fixed state and the incompletely fixed state, the lever member 61 can be completely fixed and incompletely fixed in the insertion hole 3. Since the slit 15a opens in the state,
The operator can easily confirm the completely fixed state by looking at the slit 15a.

On the other hand, in the case of disengagement, the locking projection 15b
Is gripped with a finger or the like to narrow the slit 15a,
b may enter the insertion hole 3.

In each of the third and fourth embodiments, the upper surfaces of the locking projections 11b and 15b are colored so that the completely fixed state and the incompletely fixed state of the lever member can be confirmed more reliably. Is also good. Indicator 1
The shapes of 1 and 15 are not limited to a prismatic shape, and may be changed to a cylindrical shape or the like.
