The second cover 12 includes a ceiling 12a facing the bottom plate 11b of the first cover 11, peripheral walls 12b and 12c erected from the side edge of the ceiling 12a toward the side walls 11c and 11d of the first cover 11, And they are integrally formed.

  The hinge 13 is formed across the side wall 11 c of the first cover 11 and the peripheral wall 12 b of the second cover 12. The hinge 13 is connected to the first cover 11 so that the second cover 12 can be opened and closed with respect to the opening 11 a of the first cover 11. And the hinge 13 of this embodiment is the 1st cover 11 or the 2nd cover from the open state which opened the opening 11 of the 1st cover 11 to the closed state which closed the opening 11a of the 1st cover 11 with the 2nd cover 12. 12 rotations are possible around the hinge 13.

  The pair of locking projections 14 are formed near the opening 11a of the side wall 11d facing the side wall 11c of the first cover 11 provided with the plurality of hinges 13. The locking protrusion 14 protrudes outward in the shape of a protrusion having a substantially triangular cross section in the standing direction of the side wall 11d.

  The pair of locking portions 15 are formed near the first cover 11 on the outer side of the peripheral wall 12 b of the second cover 12, corresponding to the pair of locking protrusions 14. The locking portion 15 is a U-shaped locking arm that is locked to the locking protrusion 14, and a pair of arms that are erected along the outside of the side wall 11 d of the first cover 11 from both ends of the base portion. And have. Then, the locking projection 15 is positioned between the pair of arms, and the locking projection 14 and the locking portion 15 are locked by locking the locking projection 14 and the base. Locked.

  As shown in FIGS. 4 and 5, the movement restricting means 16 protrudes from the inner surface of the bottom plate 11 b of the first cover 11 facing the bulging portion 42 c of the wire crimping portion 42 accommodated in the main body 10 toward the wire crimping portion 42. It is formed as a rib. Thus, the intensity | strength of the 1st cover 11 can be improved by making the movement control means 16 into a rib. When the terminal 4 is pulled in the longitudinal direction of the electric wire 3 (the deviation direction D in FIG. 4), the movement restricting means 16 comes into contact with the bulging portion 42c of the electric wire crimping portion 42 and the deviation direction D of the terminal 4. Restrict movement to

  As shown in FIG. 4, the movement restricting means 16 is formed so as to protrude from the inner surface of the bottom plate 11 b to the vicinity of the surface of the wire crimping portion 42. That is, the movement restricting means 16 only needs to have a shape that reliably catches with the bulging portion 42c of the wire crimping portion 42 when the terminal 4 is displaced in the displacement direction D. It can be in the form. And the movement control means 16 is designed corresponding to the magnitude | size and shape of the bulging part 42c of the electric wire crimping part 42. FIG.

  Further, in the present embodiment, since the terminal 4 is the main body portion 10 that is displaced only in the displacement direction D, the movement restricting means 16 is formed only near the electrical connection portion 41 of the wire crimping portion 42. When there is a pair of bulge portions 42c in the portion 42 and the terminal 4 may be displaced in the direction opposite to the displacement direction D, a pair of movement restricting means 16 corresponding to each of the pair of bulge portions 42c is formed. It can also be set as embodiment to do.

  Furthermore, as shown in FIG. 4, when the wire crimping portion 42 is accommodated (fitted) in the first cover 11, the movement regulating means 16 has a desired gap between the bulging portion 42 c of the wire crimping portion 42. It forms in the baseplate 11b of the 1st cover 11 so that the clearance gap S may be interposed. Thereby, even if an error occurs in the size or the like of the bulging portion 42 c, the terminal 4 can be reliably accommodated in the first cover 11. Further, by interposing a desired gap S, it is possible to absorb an error generated between the terminal 4 and the counterpart member that electrically connects the terminal 4. In the present embodiment, the case where the gap S is interposed between the bulging portion 42c of the wire crimping portion 42 and the movement restricting means 16 will be described. However, the bulging portion 42c and the movement restricting means without the gap S being interposed. It is also possible to adopt an embodiment in which 16 is abutted.

  The second cover 12 further includes an abutting portion 17 that abuts the electrical connecting portion 41 of the terminal 4 accommodated in the second cover 2B when the opening 11a of the first cover 11 is closed. The contact portion 17 is formed in a wall shape standing along the electrical connection portion 41 from the upper surface edge portion near the electrical connection portion 41 of the ceiling 12 a of the second cover 12. The contact portion 17 restricts the movement of the electrical connection portion 41 in the displacement direction D. Therefore, even when the bulging part 42c of the electric wire crimping part 42 is small, or even when an excessive force in the deviation direction D is applied to the terminal 4, the deviation of the terminal 4 can be reliably suppressed.

  According to the first housing cover 2 </ b> A described above, when the wire crimping portion 42 of the terminal 4 housed in the main body portion 10 is pulled in the longitudinal direction of the wire 3, the movement restricting means 16 is the bulging portion of the wire crimping portion 42. Since the movement of the terminal 4 is restricted by coming into contact with 42c, the displacement of the terminal 4 with respect to the longitudinal direction of the electric wire 3 can be suppressed only by housing the electric wire crimping portion 42 in the main body portion. Moreover, since it is only necessary to form the movement restricting means 16 corresponding to the swollen portion 42c by using the swollen portion 42c generated in the wire crimping portion 42 of the terminal 4, the structures of each other are complicated in order to suppress displacement. There is nothing. Furthermore, since the movement restricting means 16 is formed as a rib in the main body portion 10, the strength of the main body portion 10 can be improved. Therefore, it is possible to suppress the displacement of the terminal 4 accommodated in the main body 10 without adding a new configuration to the terminal 4.

  Further, since the movement restricting means 16 is formed on the inner surface of the first cover 11 having the opening 11a into which the wire crimping portion 42 of the terminal 4 is inserted, the wire crimping portion 42 is assembled in the first cover 11. Even during the assembly process before the opening 11a of the first cover 11 is closed with the second cover 12, the displacement of the terminals 4 can be suppressed, so that the assembly work in the main body 10 can be further simplified.

The second peripheral wall 22d and the third peripheral wall 22e are erected from the ceiling 22a toward the second side wall 21d of the main body 21 facing each other. The pair of fourth peripheral walls 22f is erected from the ceiling 22a toward each of the pair of fourth side walls 21f of the opposing main body 21.

  The hinge 23 is formed across the first side wall 21 c of the main body portion 21 and the first peripheral wall 22 c of the lid portion 22. That is, the hinge 23 is connected to the main body 21 so that the lid 22 can be opened and closed with respect to the opening 21 a of the main body 21. The hinge 23 of the present embodiment rotates the main body 21 or the lid body 22 from the open state where the opening 21a of the main body portion 21 is opened to the closed state where the opening 21a of the main body portion 21 is closed by the lid body 22. The hinge 23 is the center.

  The pair of locking projections 24 are formed near the opening 21a on the outer side of each of the second side wall 21d and the third side wall 21e facing the main body 21. Then, as shown in FIG. 1 and the like, the locking protrusion 24 is formed in a protrusion shape in which the section in the standing direction of the second side wall 21d or the third side wall 21e is substantially triangular from the second side wall 21d or the third side wall 21e.

Then, the locking projection 24 is positioned between the pair of arms 25b and 25c, and the locking projection 24 and the locking portion 25 are locked by locking the locking projection 24 and the base portion 25a. .

  Next, an assembly example of the electric wire 1 with a storage case having the above-described configuration will be described below with reference to the drawings.

  First, the wire crimping portion 4 is inserted into the opening 11a of the first cover 11 of the first housing cover 2A from the side surface of the wire crimping portion 42 of the terminal 4 having the bulging portion 42c, and the wire crimping portion is inserted into the first cover 11. When 42 is fitted, as shown in FIG. 4, the movement restricting means 16 of the first cover and the bulging portion 42 c of the wire crimping portion 42 are arranged side by side. Moreover, the electrical connection part 411 connected to the wire crimping part 42 is accommodated in the main body 21 of the second accommodation cover 2B from the opening 21a.

  Subsequently, the second cover 12 is rotated around the hinge 13 of the first housing cover 2A toward the opening 11a of the first cover 11 so that each of the pair of locking portions 15 becomes a pair of locking protrusions 14. By being brought close and locked, the second cover 12 closes the opening 11a of the first cover 11 as shown in FIG.

  Thereby, the electric wire crimping part 42 of the terminal 4 is accommodated in the 1st accommodating cover 2A. In this state, when the terminal 4 is pulled in the displacement direction D shown in FIG. 4, the bulging portion 42 c with the wire crimping portion 42 is caught by the movement restricting means 16 in the first cover 11. It is possible to surely suppress the deviation to.

Since the crimping portion 42 is accommodated so as to be juxtaposed and the opening 11a of the first cover 11 is closed by the second cover 12, the wire crimping portion 42 is assembled in the first cover 11 and the first cover 11 is assembled. Since the displacement of the terminal 4 can be suppressed even during the assembly before the 11 opening 11a is closed with the second cover 12, the assembly work can be simplified. Moreover, since it is only necessary to form the movement restricting means 16 corresponding to the bulging portion 42c using the bulging portion generated in the wire crimping portion 42 of the terminal 4, the structures of each other are complicated in order to suppress the deviation. Nor. Therefore, it is possible to suppress the displacement of the terminal accommodated in the main body without adding a new configuration to the terminal.

  In the above-described embodiment, since the electrical connection portion 41 of the terminal 4 is bent, the case where the present invention is applied to the housing cover 2 having the first housing cover 2A and the second housing cover 2B has been described. The present invention can also be applied to the housing cover 100 that houses the conventional straight terminal 4 described above.

For example, as shown in Reference Example 6-8, housing cover 100 includes a main body for accommodating the terminal 4 (first cover) 110, lid (second cover for closing the opening 111 of the cover body 110 ) 120 ′, a hinge 130 interposed between the cover body 110 and the lid body 120 ′ to connect the cover body 110 and the lid body 120 ′, the two first lock portions 140, and the two second locks. Part 150. In addition, since the basic structure of the cover body 120 and lid body 120 'mentioned above is the same, and there is no change in the basic structure of the other accommodation cover 100, only a changed part is demonstrated.

  The terminal 4 has a pair of bulging portions 42 c formed on both sides of a wire crimping portion 42 that intersects the longitudinal direction of the wire 3. The terminal 4 is fitted to the cover body 110 so that the bulging part 42 c of the wire crimping part 42 faces the opening 111 of the cover body 110. In such a case, as shown in FIGS. 6 and 8, the movement restricting means 16 described above is formed so as to protrude from the inner surface of the lid 120 toward the wire crimping portion 42.

In this reference example , a pair of movement restricting means 16 is formed corresponding to each of the pair of bulging portions 42c, and is a rib that comes into contact with the bulging portion 42 when the terminal 4 is displaced. The pair of movement restricting means 16 is formed on the lid 120 ′ so as to come into contact with the bulging portion 42c of the wire crimping portion 42 when the opening 111 of the main body 110 is closed with the lid 120 ′. Yes. Thus, by making the pair of movement restricting means 16 contact each of the pair of bulging portions 42c of the wire crimping portion 42, it is possible to prevent the terminal 4 from being displaced and to prevent the terminal 4 from rattling. As in the case of the housing cover 2 described above, a reference example in which a gap is interposed between the pair of movement restricting means 16 and the pair of bulging portions 42c of the wire crimping portion 42 can also be used.

  As described above, the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
