Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a connection type valve manifold block in which a plurality of manifold blocks are continuously arranged along a rail.

[Prior Art] The inventors of the present invention have previously proposed, in Japanese Patent Application No. 1-105461, a connection type valve manifold in which a plurality of manifold blocks are continuously arranged along a rail.

The previously proposed connection type valve manifold can be connected by a simple operation of pressing the connecting surfaces of each manifold block, but there are some points that are lacking in consideration of separation, and the valve is attached to the manifold block. Since it is necessary to operate the release lever in a direction different from that, there is a problem that a space for separating operation is required.

On the other hand, the valve mounting surface side of the manifold block has a relatively large space for mounting and removing the valve, so use this space to perform the manifold block separation operation. But,
Not only can the space be used effectively, but it can be operated in the same direction as the mounting of the valve, which facilitates the operation.

[Problems to be Solved by the Invention] An object to be solved by the present invention is to provide a connection type valve manifold in which valves can be easily arranged in series and the manifold blocks can be separated in the same direction as the mounting direction of the valves. is there.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a valve mounting surface,
In a connection type valve manifold in which a plurality of manifold blocks having a pair of continuous surfaces and pressure fluid supply passages and discharge passages communicating with each other on the continuous surfaces are serially arranged along a rail, each manifold block is The valve mounting surface has an insertion hole and an engaging portion of the connecting fitting, and one of the connecting surfaces has a pair of elastic locking pieces whose tip locking portions face each other.
On the other side of the continuous surface, there are respectively provided recesses into which a pair of elastic locking pieces of the next manifold block can be loosely inserted, and the connecting fitting has an elastic engaging portion that elastically engages with the engaging portion. Each of the manifold blocks includes a coupling fitting inserted into the insertion hole and a tip locking portion of a pair of elastic locking pieces inserted into the recess, and an elastic engagement portion of the coupling fitting and the engagement portion. It is characterized in that they are connected by elastic engagement with the joint.

[Operation] When connecting the manifold blocks, the connecting metal fitting is inserted from the insertion hole of the valve mounting surface of one of the manifold blocks to engage the elastic engaging portion with the engaging portion, and the manifold blocks are continuously installed in this state. When the surfaces are pressed together, the distal end locking portions of the pair of elastic locking pieces of the next manifold block inserted into the recesses on the other side of the continuous surface are elastically locked to the connecting fittings, and these manifold blocks are While being connected, the supply flow path and the discharge flow path communicate with each other in an airtight manner.

In this case, since the elastic engaging portion of the connecting fitting is elastically engaged with the engaging portion of the manifold block to prevent the connecting piece from coming off, the connecting fitting does not float due to the pressure contact at the time of connection.

When the elastic fitting portion of the connecting fitting is disengaged from the engaging portion and the connecting fitting is pulled out, the engagement between the connecting fitting and the tip end engaging portion is released, and the manifold block can be separated.

In this case, it is not necessary to pull out the connecting fitting from the insertion hole,
After the separation, the connecting fitting is pushed in to elastically engage the elastic engaging portion with the engaging portion, so that the connecting fitting can be prevented from being lost, and the manifold block can be connected as it is.

The above separating operation can be performed easily because it can be performed on the valve mounting surface side where there is relatively space in the space and in the same direction as the valve mounting.

[Embodiment] The drawings show an embodiment of the present invention. In this connection type valve manifold, a plurality of manifold blocks 1 are arranged in series along a rail 2 to be mounted. End block at one end of

Are formed.

On the other hand, each connecting fitting 17 has an insertion portion 17a having a U-shaped cross section,
It is provided with an elastic engaging portion 17b formed by bending upward and a laterally U-shaped detaching piece 17c on its side, and is integrally formed by a metal plate or the like (see FIGS. 2 and 3). ).

The socket mounting portion 14 includes an end face opening 14a and a thin portion 1
The lead wire 27 of the socket 26, which is provided with the lid 15 integrally connected by 5a and is inserted from the end face opening 14a,
Wiring block 4 through the side opening of socket mounting part 14
When the valve 11 is connected to the multi-pole connector 4a and the valve 11 is mounted on the valve mounting surface, the valve 11 and the socket 26 are electrically connected.

Reference numerals 28 and 29 in FIG. 1 denote a pressure fluid supply port and a pressure fluid discharge port opened in the end block 3a, which communicate with the flow passages 9 and 10 of the manifold block by flow passages (not shown). .
