These engagement pieces 18 and 19 and 2nd engaging grooves 18a and 19a which function as a to-be-engaged part opened in the arrow B direction and extended in the arrow A direction are provided between each bending part 14 and 15. .

  The end surface 5a in the arrow B direction of the bottom plate 5 is positioned in the arrow A direction by a length L than the end surfaces 7a and 8a in the arrow B direction of the side plates 7 and 8. As shown in FIG. 8A, a pair of contact pieces 20, 20 having a L-shaped cross section project from the end surface 5 a. Between the contact pieces 20 and 20 and at the end of the bottom plate 5 in the direction of arrow B, as shown in FIG. 6, a fastening portion 21 protruding toward the inside of the case 2 is provided. The fastening portion 21 is provided with a screw insertion hole 21a.

  The lower surface of the upper surface plate 11 of the cover 3 and the both ends of the end portion on the arrow A direction side are engaged with the first engaging grooves 16 and 17 as shown in FIG. First engagement pieces 23 and 24 that function as joint portions are attached. At the ends of these first engaging pieces 23, 24 in the direction of arrow A, as shown in FIG. 7B, engaging portions 23a formed in a stepped shape that engage with the lower surface 13a of the bent portion 13 are provided. 24a is provided.

  As shown in FIG. 1, the lower surface of the upper surface plate 11 of the cover 3 is engaged with the second engaging grooves 18a and 19a at both ends of the end portion on the arrow B direction side. Second engagement pieces 25 and 26 that function as parts are attached. At the ends of the second engagement pieces 25, 26 in the direction of arrow A, engagement portions 25a, 26a formed in a stepped shape that engage with the lower surfaces 18b, 19b of the engagement pieces 18, 19 are provided. It has been.

  At the lower end of the front plate 12 of the cover 3, a bent portion 27 that is bent at a right angle in the direction of the arrow A is provided, and the protruding length of the bent portion 27 is L. Yes. In the central portion of the bent portion 27, a fastening portion 28 having a cross-section in contact with the upper surface of the fastening portion 21 of the case 2 formed in an inverted L shape is provided. Is formed with a screw hole 28a. Further, at both ends of the bent portion 27, contact pieces 29, 29 each having a reverse L-shaped cross section that contacts the upper surface of the bottom plate 5 of the case 2 are provided.

  Next, a method for assembling the cover 3 to the case 2 in the electronic device casing thus configured will be described. First, in FIG. 1, both sides of the cover 3 are slid in the direction of the arrow A in a state where the both sides of the cover 3 are in contact with the bent portions 14 and 15 of the case 2, respectively. The first engagement pieces 23 and 24 of the cover 3 are engaged with each other, and the second engagement pieces 25 and 26 are engaged with the second engagement grooves 18a and 19a, respectively. At the same time, the contact pieces 29, 29 of the cover 3 are brought into contact with the upper surface of the end portion in the arrow B direction of the bottom plate 5 of the case 2 as shown in FIG. 20 is brought into contact with the upper surface of the bent portion 27 of the cover 3 as shown in FIG.

  Further, by slightly moving the cover 3 in the direction of arrow A in FIG. 1, the engaging portions 23 a and 24 a of the first engaging pieces 23 and 24 of the cover 3 are engaged with the lower surface 13 a of the bent portion 13 of the case 2. At the same time, the engaging portions 25a and 26a of the second engaging pieces 25 and 26 are engaged with the lower surfaces 18b and 19b of the engaging pieces 18 and 19, respectively. In this state, the fastening portion 28 of the cover 3 comes into contact with the fastening portion 21 of the case 2 and the screw hole 28a coincides with the screw insertion hole 21a.

  In this way, the first engaging pieces 23 and 24 of the cover 3 are engaged with the first engaging grooves 16 and 17, respectively, and the engaging portions 23 a and 24 a of the first engaging pieces 23 and 24 are arranged in the case. By engaging with the lower surface of the second bent portion 13, the movement of the cover 3 in the arrow CD direction and the vertical direction with respect to the case 2 is restricted.

  Similarly, the second engaging pieces 25 and 26 are engaged with the second engaging grooves 18a and 19a, respectively, and the engaging portions 25a and 26a of the second engaging pieces 25 and 26 are engaged with the engaging pieces 18 and 19a, respectively. By engaging with the lower surfaces 18 a and 19 a of the cover 19, the movement of the cover 3 in the arrow CD direction and the vertical direction with respect to the case 2 is restricted. The contact pieces 29 and 29 of the cover 3 are brought into contact with the upper surface of the end portion of the bottom plate 5 of the case 2 in the direction of arrow B, and the contact pieces 20 and 20 of the case 2 are placed on the upper surface of the bent portion 27 of the cover 3. By making contact, the movement of the cover 3 in the vertical direction with respect to the case 2 is restricted.

  In this state, the case 2 and the cover 3 are assembled by screwing the screw 30 inserted into the screw insertion hole 21a into the screw hole 28a from the back side of the bottom plate 5 of the case 2 as shown in FIG. Thus, the communication device housing 1 is formed.

  Thus, the engaging portions 23a, 24a of the first engaging pieces 23, 24 of the cover 3 are engaged with the lower surface of the bent portion 13 of the case 2, and the engaging portions of the second engaging pieces 25, 26 are engaged. By engaging 25a and 26a with the lower surfaces of the engaging pieces 18 and 19, the screw hole 28a coincides with the screw insertion hole 21a. For this reason, since it is not necessary to align the screw hole 28a and the screw insertion hole 21a, the screwing operation can be easily performed, and the case 2 and the cover 3 can be assembled by the single screw 30. Therefore, it can be performed for a short time.

  Further, the bent portion 13 is provided in the entire portion where the first engaging grooves 16, 17 are provided, and the bent portion 14, is provided in the entire portion where the second engaging grooves 18 a, 19 a are provided. 15 is provided, and the bent portion 27 is provided in the entire portion where the contact portions 29 and 29 are provided. For this reason, not only the strength of the portion where the first engaging grooves 16 and 17 and the second engaging grooves 18a and 19a and the contact pieces 29 and 29 are provided increases, but the case 2 and the cover 3 The mischief which tries to pry open by inserting a screwdriver etc. in the junction between can be controlled.

  In the present embodiment, the bent portions 13, 14, 14, 14, 19, the second engaging grooves 18 a, 19 a and the portions where the contact portions 29, 29 are provided are bent portions 13, 14, 15 and 27 are provided. However, when it is not particularly necessary to increase the strength, the bent portion may not be provided. In addition, the cover 3 is fastened to the case 2 by the bolts 30. However, the fastening portion 28 is formed with a long hole, and has a head and is rotatably supported by the insertion hole 21a of the fastening portion 21. Further, it may be fastened by a stopper provided with an engaging portion that engages with the end portion of the long hole on the short axis side, and various design changes are possible.
