As shown in fig. 6, the module housing unit 8 is configured to house the circuit board 6 mounted with the module 61 between the cover 5 and the case 7. The cover 5 and the case 7 are formed of a material having a small elastic modulus, such as PBT (polybutylene terephthalate) or nylon, which does not contain glass fiber. In addition, in a state where the case 7 and the cover 5 house the circuit board 6, the case 7 is provided with an insertion and extraction portion 72 on a side facing the cover 5. The insertion and extraction portion 72 provided in the housing 7 is provided with a removal groove 73. The arrangement of the detaching groove 73 will be described in detail later.

Fig. 7 is a perspective view showing the cover 5 constituting the module housing unit 8. The cover 5 is provided with an engagement claw 51. Further, leg portions 52 are provided so as to extend from the respective engagement claws 51. The engagement claw 51 has elasticity because of its snap-fit structure, and has an R-shape with a rounded tip.

Fig. 8 is a cross-sectional view of the module accommodating frame 4 as viewed from the Z direction in the oblique view shown in fig. 1. The module housing unit 8 housed in the base 3 is fixed by the engagement claw 51 of the cover 5 engaging with the engagement groove 31. The engagement will be described in detail later.

Fig. 9 is a cross-sectional view of the module storage housing 4 as viewed in the Z direction in an oblique view shown in fig. 1, showing the module storage unit 8 being inserted into and removed from the module storage housing 4. The module housing unit 8 is inserted into and removed from the cover 5 in a direction toward the engagement groove 31 of the base 3.

Fig. 10 is a side view of the module housing unit 8. Fig. 11 is a cross-sectional view of arrow B-B in fig. 10 of the module housing unit 8 in a state where the housing 7 and the cover 5 are attached. Fig. 12 is a cross-sectional view of arrow B-B in fig. 10 showing a state in which the cover 5 is being attached to the housing 7.

As shown in fig. 10 to 12, the engagement claws 51 of the cover 5 are pressed into the module 61 from the side wall of the housing 7 and elastically deformed.

The circuit board 6 is accommodated in the module accommodating unit 8 by the engagement of the engagement claws 51 of the cover 5 with the engagement holes 71 of the housing 7. The engagement claw 51 for engaging the cover 5 and the case 7 is projected from the side wall of the case 7 through the engagement hole 71.

Next, the engagement between the engagement claws 51 and the engagement holes 71 of the cover 5 and the engagement grooves 31 of the housing 9 will be described.

Fig. 13 is an enlarged view of a portion a shown in fig. 8. Each part of the engagement claw 51 in a state where the engagement claw 51 is engaged with the engagement hole 71 will be described with reference to fig. 13.

As shown in fig. 13, if the module housing unit 8 is housed in the housing 9, the engagement claws 51 engage with the engagement holes 71 provided in the case 7. The engagement claw 51 engaged with the engagement hole 71 protrudes toward the base 3 through the engagement hole 71, and engages with the engagement groove 31 of the base 3.

As shown in fig. 13, the engagement claw 51 includes a fixed surface 51a and an inclined surface 51 b. The fixing surface 51a is provided in connection with the leg 52. The fixing surface 51a faces the side surface of the engagement hole 71. The angle between the fixing surface 51a and the direction of insertion of the module housing unit 8 into the housing 9 is 90 degrees or less. The inclined surface 51b is provided toward the opening portion in succession to the fixed surface 51 a. The angle formed by the inclined surface 51b and the direction of insertion of the module housing unit 8 into the housing 9 is less than 90 degrees.

The module housing unit 8 is not detached from the frame 9 in a state where the engagement claws 51 are engaged with the engagement holes 71 and the engagement grooves 31. As shown in fig. 9, when the worker pulls out the module housing unit 8 from the housing 9 with a certain load, the engagement claw 51 is elastically deformed to disengage from the engagement groove 31, so that the module housing unit 8 can be taken out from the housing 9.

Fig. 14 is an oblique view of the housing 7. The insertion and extraction portion 72 is provided on the housing 7 aligned with the positions of the opening 3a of the base 3 and the opening 1a of the cover 1 in a state where the module housing unit 8 is housed in the housing 9. The removal groove 73 is provided along the opening 3a and the opening 1a over the entire circumference of the insertion and extraction portion 72. The worker grasps the detaching slot 73 to detach the module housing unit 8 from the frame 9.

When the components of the device such as the breaker having the module housing case 4 are disposed adjacent to the module housing case 4, if the removal groove 73 is provided only in a part, it becomes difficult for the operator to grasp the removal groove 73, and there is a possibility that it becomes difficult to remove the module housing unit 8 from the case 9. Therefore, when the module housing cases 4 are shared, the insertion/removal direction of the module housing units 8 is limited, and the degree of freedom in designing the device may be reduced.

However, since the removal grooves 73 are formed over the entire circumference of the insertion/removal portion 72, the housing direction of the module housing units 8 is not limited when the module housing frames 4 are shared, and thus the degree of freedom in designing the device can be improved.

According to the present embodiment, the module housing unit 8 can be detached from the frame 9 without adding components, and the number of components is reduced. In addition, the cost can be suppressed with the reduction of the number of components. Further, since no new component is required when the module housing unit 8 is removed, a space for accommodating components used for removal in the housing 9 can be reduced.

Further, since the engagement claws 51 of the cover 5 have elasticity, the worker feels a click when the module housing unit 8 is attached to the housing 9. The operator can easily determine the completion of the mounting based on the click feeling.

Further, by providing the removal groove 73 over the entire circumference of the insertion/removal portion 72 of the housing 7, the mounting direction of the module housing unit 8 is not limited, the module housing frame 4 can be shared easily, and the degree of freedom in designing the device can be increased.
