DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a cylindrical housing body in which a lid body is attachable to and detachable from a tubular body having a housing section inside, and particularly, the lid body is a main body. Regarding the structure to be fixed to.

(b) Conventional technology A quick-connect type wire connecting device in which lead wires are connected to a fluorescent lamp socket or the like internally connects a terminal of the fluorescent lamp and a power supply line. For this reason, it has a connection part for a socket for a fluorescent lamp terminal and a power supply line inside. A device for accommodating an object to be accommodated therein, such as this quick-connect type wire connecting device, includes a tubular main body having at least one open end, and a lid body detachably attached to the open end of the main body. A cylindrical container is used as a general shape. In this case, when the object to be stored that is to be shielded from the outside is stored inside the main body, the cover must be completely fixed to the main body when the cover is attached to the open end of the main body. In particular, when storing the wiring parts of electrical parts, such as a quick-connect type wire connection device, in order to prevent electric shock accidents and leakages, and to prevent connection failures due to ingress of dust, cover the main body Must be securely fixed.

Therefore, in the conventional cylindrical container, as shown in FIG. 7 (A), a protrusion 71a is formed on a part of the inner peripheral surface of the main body 71 on the open end side, and a part of the outer peripheral portion of the lid 72 is formed. In some cases, a lid-side protrusion 72a that engages with the main-body-side protrusion 71a is formed. The main body side projection 71a and the lid side projection 72a are engaged with each other to fix the lid body 72 in the state of being fitted into the main body 71.

(c) Problems to be Solved by the Invention However, in the conventional cylindrical storage body, the main body side protrusion 71a
The contact surface of the lid-side projection 72a was perpendicular to the fitting direction. Therefore, as shown in FIG. 7 (B), in the lid 72, the stepped portion 72 with which the end surface 71b of the main body 71 abuts.
If an error occurs in the dimension between b and the contact surface 72c of the lid-side projection 72a, the lid 72 can move with respect to the main body 71 within this error range, and the lid 7 can be moved relative to the main body 71.
There was a drawback that 2 could not be fixed securely.
Such dimensional error is likely to occur particularly in resin molding, and also occurs due to deformation of both protrusions when the lid 72 is repeatedly attached to and detached from the main body 71. If the lid 72 cannot be securely fixed to the main body 71 due to such a dimensional error of the protrusion, not only the appearance is deteriorated due to the gap between the main body 71 and the lid 72, but also the stored object and the external When the object to be stored is a connection part of an electric component, there is a problem that intrusion of dust causes a contact failure or the like.

The object of the present invention is to make it possible to absorb the dimensional error of the protruding portion at the abutting surface by forming one or both of the abutting surfaces of the main body side projection and the lid side projection by an inclined surface, Even if an error occurs, the lid can be securely fixed to the main body, a gap is not created between the main body and the lid, the appearance of the appearance is kept beautiful, and dust invades into the main body. Another object of the present invention is to provide a cylindrical storage body that can prevent the lid body from falling and being damaged by movement.

(d) Means for Solving the Problems The tubular housing of the present invention comprises a tubular main body having at least one open end, and a fitting body having a fitting portion fitted into the main body from the open end. In the cylindrical storage body, the main body side wedge-shaped protrusion having a wedge-shaped cross-section whose projection amount increases as it goes into the main body is formed at a plurality of locations on the inner peripheral surface of the open end of the main body, and A lid-side wedge-shaped protrusion having a wedge-shaped cross-section, in which a protrusion amount increases in a direction opposite to the body-side wedge-shaped protrusion on the outer peripheral surface of the fitting portion of the lid, in a direction opposite to a direction in which the lid is fitted into the body. And a sloped surface on the back surface of the main body side wedge-shaped projection where the projection amount decreases from the maximum projection position into the main body,
One or both of the sloped surface and the sloped surface where the projection amount decreases from the position where the projection amount is the maximum to the direction opposite to the fitting direction is formed on the back surface of the wedge-shaped projection on the lid side. After passing over the other wedge-shaped protrusion, the movement of the lid body in the fitting direction is restricted by the contact between the open end of the main body and the lid body, and the back surface of each of the two wedge-shaped projections abuts each other. It is characterized in that movement of the body in a direction opposite to the fitting direction is restricted.

(e) Action In this invention, one or both of the contact surfaces of the main body side projection and the lid side projection is constituted by an inclined surface. Therefore, as shown in FIG. 5 (A), the main body side projection 3 and the lid side projection 4 come into contact with each other via the inclined surface, and the inclined surface 3
The contact portion formed by a and the corner portion 4a is urged in the fitting direction indicated by arrow A. Due to this biasing force, the lid 2
Moves in the fitting direction until the stepped portion 2a contacts the end surface 1a of the main body 1. Therefore, as shown in FIGS. 5B and 5C, when a dimensional error occurs between the contact position of the inclined surface 3a and the corner portion 4a and the contact position of the end surface 1a and the stepped portion 2a, The contact position of the inclined surface 3a and the corner portion 4a moves in the fitting direction of the lid body 2 to absorb this dimensional error. Therefore, the dimensional error in the protrusion is
The end surface 1a of the main body 1 and the stepped portion 2a of the lid 2 are always in contact with each other within the range of the length of a in the fitting direction. Further, even in this case, since the corner portion 4a is continuously urged in the fitting direction, the main body 1 and the lid body 2 between the end surface 1a and the step portion 2a.
The contact force between and is continuously maintained.

(f) Embodiment FIG. 3 is an assembly view of a cylindrical housing which is an embodiment of the present invention applied to a quick-connect wire connecting device.

Inside the main body 1 formed in a hollow cylindrical shape, a hole 6a is formed.

After that, the power supply line is easily inserted between the conductor 13 and the leaf spring 15 by inserting the power supply line from the hole 2e and removing the spacer 14 from the square hole 2d. As described above, the terminals of the lamp can be electrically connected to the power supply line through the conductors 11 and 13 and the spring 12 in the main body 1 of the quick-connect type wire connecting device.

Protrusions 3 are provided at two locations on a part of the inner peripheral portion of the main body 1 on the side of the open end 5. The flange 6c of the movable body 6 is provided with two notches 7 at positions facing the main body side projection 3. Further, the main body side projection 3 is formed on a part of the outer peripheral surface of the lid body 2.
Lid-side protrusions 4 are formed at two positions facing each other. Therefore, when assembling the quick-connect wire connecting device, the conductor 13 is inserted into the lid body 2, the conductor 11 and the spring 12 are inserted into the movable body 6, and the spring 12 and the conductor 13 are engaged. The lid body 2 and the movable body 6 are integrated by combining them. In this state, the notch 7 is made to face the main body side projection 3 of the main body 1 so that the movable body 6
Then, the lid 2 is inserted so that the lid-side projection 4 faces the main-body-side projection 3. As a result, the lid-side projection 4 is engaged with the main-body-side projection 3, and the lid 2 is fixed to the main body 1 by abutting them.

As shown in FIG. 1 (B), the main-body-side protrusion 3 has a mountain-like shape on its side surface and is composed of two inclined surfaces. On the other hand, the lid-side protrusion 4 is formed in a wedge shape by one inclined surface and one vertical surface.

As shown in FIG. 4, when the lid body 2 is fitted in the body 1 in the direction of arrow A, the body side projection 3 comes into contact with the lid body side projection 4 and then is housed in the groove 2b of the lid body 2. As a result, the main body side protrusion 3 and the lid side protrusion 4 are engaged with each other. At the time of this engagement, as shown in FIG. 5 (A), the inclined surface 3a of the main body side projection 3 and the corner portion 4a of the lid side projection 4 contact. The corner portion 4a is biased in the direction of arrow A, which is the fitting direction, by the inclination of the inclined surface 3a. On the other hand, the stepped portion 2a of the lid body 2 abuts on the end surface 1a of the main body 1, and this abutment restricts the movement of the lid body 2 in the direction of arrow A. Therefore, the lid 2 has the inclined surface 3 of the main body side protrusion 3.
It is securely fixed to the main body 1 in a state of being urged in the direction of arrow A by the contact between a and the corner portion 4a of the lid-side projection 4.

When the length between the step portion 2a and the corner portion 4a is formed shorter than the reference dimension in the lid body 2, as shown in FIG. 5 (B), the corner portion 4a has the inclined surface 3a. The step portion 2a comes into contact with the end surface 1a in a state of coming into contact with the position from the open end. Further, when the length between the step portion 2a and the corner portion 4a is formed longer than the reference dimension, the corner portion 4a is positioned from the inside of the inclined surface 3a as shown in FIG. 5 (C). The step portion 2a comes into contact with the end surface 1a in the state of being brought into contact with. Therefore, the dimensional error in the protrusion is absorbed by the change of the contact position of the corner 4a on the inclined surface 3a, and the step 2a always contacts the end surface 1a.
