Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotary connector used when another board is connected to another board.

[0002]

[Prior Art]

 Conventionally, when connecting a board and another board, as shown in FIGS. 13 and 14, for example, a connector 100 composed of a pair of rotatable base members 101 and connector members 102 while maintaining electrical connection is used. The boards 103 and 104 are attached to the base member 101 and the connector member 102, respectively. As shown in the exploded views of FIGS. 15 and 16, this connector 100 has a connector member 102 provided with a protrusion 102a serving as a rotation shaft, and a base member 101 having a recess 101a into which the protrusion 102a of the connector member 102 is fitted. Is forming.

[0003]

[Problems to be solved by the device]

 In the above-described conventional connector, since it is only rotatably held by the contact pressure between the protrusion of the connector member and the recess of the base member, the base member and the connector are rotatably supported by external force such as vibration during transportation. Since the members may separate, it is difficult to hold the board with the connector alone. Also, since there is no fixed part within the rotation range, it cannot be fixed in the upright position or the intermediate position.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides, for example, a guide groove for guiding a protruding portion for a rotary shaft provided in a connector member in a base member, and a locking protrusion in the base member so that the connector member has An engaging portion that engages with the locking protrusion is provided, and a sliding surface that guides rotation is formed on the connector member.

[0005]

Since the rotating shaft protrusion of the connector member moves while being guided by the guide groove of the base member, the connector member can be rotated with respect to the base member, and the locking protrusion of the base member can be connected to the connector member. The connector member is held at a predetermined position by engaging with the engaging portion.

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 is a side view of the connector according to the present invention in an exploded state, FIG. 2 is a front view of FIG. 1, FIG. 3 is a perspective view of a main part of FIG. 1, and FIGS. Fig. 7 is a side view of the connector in a used state, Fig. 8 is a side view of the connector in another used state, Fig. 9 is a front view of Fig. 8, and Fig. 10 is a state of Fig. 5. 11 is a perspective view of the state of FIG. 6, and FIG. 12 is a perspective view of the state of use of FIG.

The connector 1 is composed of a base member 2 and a connector member 3 which are rotatable while maintaining an electrical connection, and a rotary shaft projection 5 is provided on the inner side surfaces of both side portions 4 of the connector member 3. On both sides 6 of the member 2, guide grooves 7 for guiding the movement of the rotary shaft protrusion 5 are formed. One end of this guide groove 7 is an open end for inserting the protrusion 5, and a protrusion 7a is formed near the end so that the protrusion 5 can be held at the end.

Further, locking projections 8 are provided on both sides 6 of the base member 2, and locking projections 8 are slidable on both sides 4 of the connector member 3 so that the locking projections 8 engage. The hook portion 11 having the engaging portions 9 and 10 is formed.

Further, the connector member 3 is formed with a slide surface 12 for guiding rotation by abutting on the corners 6a of both side portions 6 of the base member 2 and sliding. A board 15 is attached to the base member 2 and a board 16 is attached to the connector member 3.

In the connector 1 configured as described above, when the connector member 3 is connected to the base member 2, the rotary shaft projection 5 of the connector member 3 is inserted into the guide groove 7 of the base member 2 as shown in FIG. Insert from the open end of to the point P1 in the guide groove 7.

Thereafter, as shown in FIGS. 5 and 10, the connector member 3 is tilted down so that the corner portions 6 a of the both side portions 6 of the base member 2 come into contact with the guide surface 12 of the connector member 3, and the connector member 3 is further attached. The guide surface 12 slides on the corner 6a due to the acting force by tilting it down, and as shown in FIGS. 6 and 11, the rotary shaft protrusion 5 of the connector member 3 is located at the P2 point of the guide groove 7 of the base member 2. Moved to and held.

Here, by raising the connector member 3 as shown in FIG. 7, since the rotary shaft protrusion 5 is held at the point P2 of the guide groove 7, the connector member 3 rotates in the same position. Then, the locking projection 8 of the base member 2 is engaged with and held by the engaging portion 9 of the hook portion 11 of the connector member 3, and the connector member 3 is held in the state shown in FIG.

By further raising the connector member 3 from this state, as shown in FIGS. 8, 9 and 12, the locking projection 8 of the base member 2 is once disengaged from the engagement portion 9 and the engagement portion 10 is released. , The connector member 3 is held in the upright state.

In this case, the base member 2 and the connector member 3 are rotated by the engagement of the guide groove 7 having an open end and the rotary shaft projection 5, so that the base member 2 and the connector member 3 can be easily attached / detached and used. Makes it hard to come off. Further, the connector member 3 can be fixed at a plurality of angles by the engagement between the locking projection 8 and the engaging portions 9 and 10.

In the illustrated example, the connector member 3 is provided with the rotary shaft protrusion 5, the engaging portions 9 and 10 that engage with the lock protrusion, and the slide surface 12, and the base member 2 is provided with the rotary shaft protrusion. Although the protrusion 7 and the groove 7 for guiding the rotary shaft projection are provided, the rotary shaft projection 5, the engaging portions 9 and 10 for engaging the lock projection and the slide surface 12 are provided on the base member 2. The connector member 3 may be provided with the rotary shaft protrusion 8 and the groove 7 for guiding the rotary shaft protrusion.

[0017]

[Effect of the device]

 As described above, according to the present invention, the base member is provided with the guide groove for guiding the rotary shaft projection provided on the connector member, and the base member is provided with the locking projection to lock the connector member. Since the engaging part that engages with the projecting part is provided and the connector member is formed with the sliding surface that guides the rotation, the fixing angle can be changed while maintaining the electrical connection, and the detachment is easy. Moreover, it is difficult for the connector to come off, and the board can be held by the connector alone, so that the structure can be simplified.
