The present invention relates to a power outlet (also called an outlet) installed in a vehicle, for example, for the purpose of operating household electrical equipment in a vehicle.

Conventionally, this type of outlet includes, for example, an outlet described in Patent Document 1. In the outlet of Patent Document 1, as shown in FIG. 17, a rotor cover 106 covering the fitting hole 146 of the outlet body 102 is rotatably provided in the outlet body 102. The rotor cover 106 is formed with an insertion hole 166 that coincides with the fitting hole 146 at the use position. The torsion coil spring 107 is arranged in the hole 102a provided in the outlet body 102. Each of the terminal portions 107b protruding radially outwardly of the torsion coil spring 107 has an elongated groove portion 102b (see FIG. 18) of the outlet body 102 and an elongated groove portion formed in the rotor cover 106 ( (Not shown). The rotor cover 106 closes the fitting hole 146 of the outlet body 102 in the rotationally elastic pressing position by the torsion coil spring 107, that is, in an unused position.

[Patent Document 1] Patent No. 3299309

According to the patent document 1 mentioned above, the torsion coil spring 107 is arrange | positioned in the hole 102a of the outlet body 102 (refer FIG. 18). And the torsion coil spring 107 is elastically deformed in the direction which generally makes a coil diameter small. Therefore, when the rotor cover 106 is rotated to the use position by using the elastic deformation of the torsion coil spring 107, between the outer circumferential surface of the torsion coil spring 107 and the inner wall surface of the hole 102a of the outlet body 102. Since the torsional coil spring 107 is shaken because the interval 100S becomes large, there is a fear that the stability of the rotor cover 106 is impaired in severe cases. In addition, since the rotating shaft 164 of the push pin is a shaft diameter that is about 1/2 to 1/3 smaller than the inner diameter of the torsion coil spring 107, as shown in FIG. 18, the torsion coil spring 107 supports the torsion coil spring 107. It did not have a function. That is, in Patent Document 1, there is no design to prevent the torsion of the torsion coil spring 107.

In addition, since the respective end portions 107b of the torsion coil spring 107 are fitted into the elongated groove portions 102b formed on the outer body body 102 and the rotor cover 106, the torsion coil springs 107 are inserted. ) Was troublesome assembly.

A support shaft portion is provided between the outlet body and the rotor cover to fit within the coil portion of the torsion coil spring and to support the coil portion of the torsion coil spring.

Further, by utilizing the relative rotation of the outer body and the rotor cover, each terminal portion of the torsion coil spring is fixed to the outer body and the rotor cover.

According to the outlet configured as described above, the fitting hole of the outlet body is closed by the rotor cover when the rotor cover rotatably installed in the outlet body is in the state of being elastically pressed in the non-use position by the torsion coil spring. Therefore, it is possible to prevent or reduce the intrusion of foreign matter into the fitting hole of the outlet body.

In addition, when using the outlet, the insertion terminal of the plug for the outlet is inserted into the fitting hole of the outlet body through the insertion hole of the rotor cover while the rotor cover is rotated to the use position using the elastic deformation of the torsion coil spring. The outlet plug can be connected to the outlet.

The support shaft portion provided between the outer body and the rotor cover can prevent or reduce the shaking of the coil portion of the torsion coil spring. In particular, when the torsion coil spring is elastically deformed in the direction of decreasing the coil diameter as the rotor cover is rotated to the use position, the torsion coil spring is reduced by decreasing the distance S between the inner circumferential surface of the torsion coil spring and the outer circumferential surface of the support shaft portion. The shake of the coil portion can be effectively suppressed. This is beneficial for improving the stability of the rotor cover.

In addition, by using the relative rotation of the rotor cover with respect to the outer body, each end portion of the torsion coil spring is fixed to the outer body and the rotor cover, respectively, it is possible to easily assemble the torsion coil spring.

Locking portions are provided which the terminal portions can abut against each other in the circumferential direction.

According to the outlet configured as described above, the respective end portions of the torsion coil spring are relatively abutted with respect to the circumferential direction by using the relative rotation of the rotor cover with respect to the outer body when the engaging portions provided on the outlet body and the rotor cover are respectively. Therefore, the assembling position of each terminal portion of the torsion coil spring with respect to the outlet body and the rotor cover is not limited to a fixed position, and the assembling range of the terminal portion can be expanded, and each terminal portion of the torsion coil spring can be easily assembled. .

In addition, the outlet according to claim 3 of the claims is the outlet according to claim 2, wherein the locking portion can position the coil portion of the torsional coil spring.

According to the outlet configured in this way, the engaging portion can be used for positioning the torsion coil spring.

In addition, the outlet according to claim 4 of the claims is the outlet according to any one of claims 1 to 3, wherein the spring for accommodating the torsion coil spring in at least one member of the outlet body and the rotor cover. An accommodation recess is provided.

The coil portion 7a is configured to be supported by relatively inserting the support shaft portion 64 of the rotor cover 6 into the hollow portion thereof (see FIGS. 4 and 5). In addition, the lower part of the coil part 7a is fitted in the left and right wall surfaces 42b of the spring accommodating recessed part 42 of the said outlet cover 4, and the positioning surface 43a of the two locking parts 43, and is located (See FIG. 10). Similarly, the upper portion of the coil portion 7a is fitted into the positioning surface 63a of the two locking portions 63 together with the left and right wall surfaces 62b of the spring receiving recess 62 of the rotor cover 6 to position the same. It becomes the structure that becomes. In addition, each terminal portion 7b may be in contact with the locking surface 43b of the locking portion 43 of the outlet cover 4 or the locking surface 63b of the locking portion 63 of the rotor cover 6, respectively. It is.

As shown in Fig. 7, the screw 8 is made of, for example, a pan tapping screw made of stainless steel, and has a cross-headed head 8a and a tapping screw shaft 8b. The tapping screw shaft portion 8b can be screwed into the hollow portion of the support shaft portion 64 of the rotor cover 6.

The washer 9 is made of, for example, a resin such as Juracon excellent in self-lubrication, and is formed in a ring plate shape having a hollow portion 9a that can be fitted to the tapping screw shaft portion 8b of the screw 8. . The washer 9 is interposed between the normal portion 45 of the outlet cover 4 and the head 8a of the screw 8 and includes a rotor 8 with respect to the outlet cover 4. The cover 6 is configured to smoothly rotate (see FIGS. 4 and 5).

Next, an example of the assembly procedure of the said component is demonstrated.

First, the torsion coil spring 7 is fitted into the spring receiving recess 42 of the outlet cover 4. At this time, the coil portion 7a of the torsion coil spring 7 is positioned at a predetermined position, i.e., shaft hole, by the left and right wall surfaces 42b of the spring accommodating recess 42 and the positioning surfaces 43a of the two locking portions 43. It is positioned so as to be substantially concentric with 44 (see Fig. 10).

Further, the lower terminal portion 7b of the torsion coil spring 7 abuts on the spring seating surface 62 of the spring receiving recess 42 of the outlet cover 4, that is, the spring receiving recess 42 It can be arrange | positioned in arbitrary positions as long as it is a range which can be contacted on the spring seating surface 62a in the vicinity of the front and back both wall surfaces 42c (refer FIG. 8) of (). . Therefore, according to the conventional technique (see FIG. 18), it is not necessary to align the terminal portion 107b to the elongated groove portion 102b one by one. The same applies to the case where the torsion coil spring 7 is arranged upside down.

At this time, the upper part including the terminal portion 7b on the upper side of the torsion coil spring 7 protrudes onto the convex portion 41 of the outlet cover 4 (see FIGS. 4 and 5).

Next, the support shaft portion 64 of the rotor cover 6 is inserted into the coil portion 7a of the torsion coil spring 7 and further into the shaft hole 44 of the outlet cover 4. At this time, for example, when the terminal portion 7b on the lower side of the torsion coil spring 7 is within the spring seating surface 42a on the front side of the outlet cover 4, the rotor cover (in the direction of the upper terminal portion 7b in the directing direction). The second fitting hole 47 of 6) corresponds. Moreover, when the terminal part 7b of the lower side of the torsion coil spring 7 is in the spring seating surface 42a of the rear side of the outlet cover 4, the rotor cover 6 in the semi-directional direction of the upper terminal part 7b. ) Corresponds to the first fitting hole 46. In this state, when the support shaft portion 64 of the rotor cover 6 is inserted into the shaft hole 44 of the outlet cover 4, the rotation angle regulating projection 68 of the rotor cover 6 causes the outlet cover 4 to extend. Abuts on the convex portion 41. Thus, the cover plate portion 60 of the rotor cover 6 is half-fitted into the rotor water recessed portion 40 of the outlet cover 4.

In this state, the rotor cover 6 is rotated in the right rotation direction. Then, when the terminal portion 7b on the upper side of the torsion coil spring 7 corresponds to the spring seating surface 62a of the spring receiving recess 62 of the rotor cover 6, it is inserted into the spring receiving recess 62. Lose. This is the same as the case where the terminal portion 7b of the lower side of the torsion coil spring 7 is brought into contact with the spring receiving recess 42 of the outlet cover 4 on the spring seating surface 62a.

Subsequently, the engaging surface 43b of the engaging portion 43 located near the left rotational direction in the rotor cover 6 abuts against the terminal portion 7b on the upper side of the torsion coil spring 7.

Then, the torsion coil spring 7 follows the rotation of the rotor cover 6. Thereby, the terminal part 7b of the lower side of the torsion coil spring 7 comes into contact with the locking surface 43b of the locking part 43 located in the vicinity of the right rotation direction in the outer cover 4 ( See FIG. 10). This is the same as the case where the terminal portion 7b on the upper side of the torsion coil spring 7 abuts against the locking surface 63b of the locking portion 63 of the rotor cover 6.

Further, the torsion coil spring 7 is elastically deformed in the direction of decreasing the coil diameter as the rotor cover 6 rotates. Then, the rotation angle regulating projection 68 of the rotor cover 6 is fitted into the rotation angle regulating groove 48 of the outer cover 4, and the cover plate portion 60 of the rotor cover 6 is the outerlet. It fits completely in the rotor accommodating recess 40 of the cover 4. At this time, the coil portion 7a of the torsion coil spring 7 is supported at a predetermined position, i.e., by the left and right wall surfaces 62b of the spring accommodating recess 62 and the positioning surfaces 63a of the two locking portions 63. It is positioned in a state substantially coaxial with the shaft portion 64. In addition, the annular flange 69 of the rotor cover 6 slidably abuts on the small protrusion 49 in the rotor accommodating recess 40 of the outlet cover 4. In addition, the lower end surface of the support shaft portion 64 of the rotor cover 6 is located on substantially the same plane as the lower end surface of the cylindrical portion 45 of the outlet cover 4.

Next, the screw 8 is screwed into the support shaft 64 of the rotor cover 6 from the lower surface side of the outlet cover 4. Specifically, the tapping screw shaft portion 8b of the screw 8 is inserted into the hollow hole 9a of the support shaft portion 64 of the rotor cover 6 via the hollow hole 9a of the washer 9. Then, while the washer 9 is fastened to the support shaft 64 of the rotor cover 6, the washer 9 is slidably abuts or comes close to the cylindrical portion 45 of the outlet cover 4. Thereby, the rotor cover 6 is prevented from being pulled out with respect to the outlet cover 4 (refer FIG. 4 and FIG. 5).

In this state, the rotor cover 6 is elastically pressurized in the left rotational direction by the elastic restoring force of the torsion coil spring 7, and the rotation angle regulating projection 68 of the rotor cover 6 is removed from the outlet cover 4. The stopper surface 48a on the right side of the rotation angle regulating groove 48 abuts. Thus, the rotor cover 6 is maintained in the "non-use position". In this state, as shown in FIG. 3, the fitting holes 46 and 47 of the outlet cover 4 are closed by the rotor cover 6. Therefore, it is possible to prevent or reduce the intrusion of foreign matter into the outlet body 2 from each of the fitting holes 46 and 47.

When the outlet 1 is used, the rotor cover 6 is rotated in the right rotational direction, that is, in the direction of the arrow 65 attached to the rotor cover 6 by using the elastic deformation of the torsion coil spring 7. Then, the rotor cover 6 is "used" because the rotation angle regulating projection 68 of the rotor cover 6 abuts against the left stopper surface 48a of the rotation angle regulating groove 48 in the outlet cover 4. Position "(see Figure 2). In this state, the respective insertion holes 66, 67 of the rotor cover 6 correspond to the respective fitting holes 46, 47 of the outlet cover 4, whereby the respective fitting holes 46, 47 Opening.
