DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connection device for draw-out type equipment that opens and closes electrical circuits.

[Prior Art] A drawer type device includes a fixed side device and a drawer side device, and by moving the drawer side device, connection/disconnection operations are performed for each connecting conductor provided in each device. Generally, a connecting device is used to connect the respective connecting conductors. This connecting device has a structure in which it is engaged with one connecting conductor and clamps the other connecting conductor, thereby electrically connecting the respective connecting conductors. Therefore, in this connection device, a pressing means such as a spring is provided to urge the connection conductors with a large force in the clamping direction so that the connection conductors do not easily separate. Therefore, when the connecting conductor is inserted into or removed from the connecting device, a large force is required in the drawing direction. In addition, for example, when connecting a connection device attached to a vertical bus bar of each phase led out vertically and a connection conductor of each phase provided on a side surface parallel to the pull-out direction of the draw-out side device, the conventional connection device Since the connecting conductor cannot pass through the inside, the connecting devices for each phase had to be disposed diagonally with steps.

[Problems to be Solved by the Invention] As described above, since the connecting device of the conventional drawer structure equipment is always pressed in the direction of pinching the connecting conductor, it is difficult to attach or remove the connecting conductor from the connecting device. A large force was required in the withdrawal direction. In addition, with conventional connection devices, it is not possible to arrange the connection devices for each phase parallel to the drawing direction, so they must be installed diagonally with a step, resulting in a large device. there were.

The present invention has been made to solve the above-mentioned problems, and in order to facilitate the separation of each connecting conductor from the connecting device and to achieve miniaturization of the device, The purpose is to obtain a connecting device that can be installed in parallel.

[Means for Solving the Problem] A connecting device for a pull-out structure device according to the present invention anchors one of the corresponding connection conductors in which each phase is arranged parallel to the pull-out direction of the pull-out structure device, and connects the other to the corresponding connection conductor. Sentences that are sandwiched between each other
a connector disposed in a shape of I, an engaging means for engaging the connector and the one connection conductor, a pressing means for pressing the opposing connectors in mutually opposing directions; Each phase is inserted between opposing surfaces of respective connectors that are sandwiched between connecting conductors arranged in parallel, and the insertion portion is provided with an operating means that is approximately elliptical in cross section orthogonal to the insertion direction. It is.

[Function] The connecting device according to the present invention has an operation means having a substantially elliptical cross section between the opposing connectors of each phase that are arranged parallel to the pull-out direction of the pull-out structure equipment, and the longitudinal direction thereof is the gap between the connectors. Push in parallel. Next, the operating means is rotated 90 degrees to spread the space between the respective connectors, and the drawer-side device is moved to place the connecting conductor between the corresponding connectors. Next, the operating means is rotated 90@ to sandwich the connecting conductor between the connectors pressed in opposite directions.

Finally, the operating means is pulled out from between the connectors of each phase, and the connection conductors of each phase are electrically connected.

[Embodiment] Hereinafter, an embodiment of a connection device for a drawer structure device of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a connecting device according to an embodiment of the present invention, and FIG. 2 is a plan view of a drawer structure using the connecting device of FIG. 1. In FIG. 1, a connecting conductor 7 is fixed to a vertical bus bar 8 with its end leading out to the left.

The connecting device 1 is attached to the end of this connecting conductor 7,
The connecting device 1 has connectors 1a facing above and below the connecting device 1,
A connecting conductor 7 is disposed between la, and is fixed to the connecting conductor 7 by vertically penetrating each with a pin 10. Approximately in the center of the connectors 1a and la are the connectors 1a and 1a, respectively.
A pressing means for pressing la in the opposite direction is provided.

As shown in FIG.
A bolt 3 that passes through a, la and the connecting conductor 7, and a double nut that fixes this bolt 3) 5, 5. Between the washer 4, the head of the bolt 3, and one of the connectors 1a, the two opposing receivers are provided with a metal fitting 6.6, and the receiver is provided with a pressing spring 2 between the metal fittings 6.6. It is something to do. Also, the connector fa
, la are provided with recesses lb, lb on the left side of the pressing means, and these recesses 1b, lb
The structure is such that an operating means, for example an operating rod 9 having a substantially elliptical cross section, can be pushed in between from outside the drawer-type device. Further, the connector has a convex portion on the left end of the opposing surfaces 1a and 1a, and has a structure for sandwiching the connecting conductor 11 of the drawer side device 12.

Connection device l of an embodiment of the present invention configured as described above
The operation when this is installed in the drawer structure shown in FIG. 2 will be explained. Is the lead-out structure equipment in Figure 2 connected conductors for each phase? ,
7.7 are arranged parallel to the moving direction of the drawer side device 12, and the connecting device l is a connecting conductor for each phase. , 7.7, two sets each are provided.

In such a drawer structure device, when connecting the connecting conductor 11.11.11 of the drawer side device 12 to the corresponding connection device 1.1.1, the operation rod 9 is connected to the connector of each phase from the outside of the drawer structure device. Insert between recesses 1b and lb of 1a and 1a. At this time, since the operating rod 9 is pushed in with the long axis direction of its cross section in the horizontal direction, the operating rod 9 does not come into contact with the connectors 1a and la. Next, the operating rod 9 is rotated 90 degrees so that the long axis direction of the operating rod 9 is vertical, and the connectors 1a are opposed to each other.

Expand the space between la. As a result, the connecting conductors 11, 11
゜11 can be passed between the connectors 1a and la, and by moving the drawer side device 12 in the direction of arrow A, connect the connecting conductor 11.11.11 of each phase to the corresponding connecting device 1.1 of each phase. ．．
It is placed between the connectors 1a and 1a of 1. Next, the operating rod 9
is rotated 90' so that the long sleeve direction is horizontal, and the connecting conductors 1.1.1 of each phase are sandwiched between the connectors 1a and 1a pressed in opposite directions by the pressing means. Finally, operation stick 9
is pulled out between the connectors 1a and la of each phase, and the connecting conductor 11.11.11 of each phase is electrically connected to the corresponding connecting conductor 7°7.7 of each phase via the connecting device 1.1.1. be done.

In addition, in the connection device 1 in the above embodiment, the connection conductor 1
Although the insertion direction of 1 was parallel to the insertion direction of the operating rod 9,
It goes without saying that the same effect can be obtained even if a drawer-type device is provided so that the connecting conductor 11 is inserted in the direction perpendicular to the pushing direction of the operating rod 9, for example, from the left side of the connecting device 1 in FIG.
