Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a sandwich arrangement system including at least two valve assemblies on a serial connection plate, a height adapter used in such a sandwich arrangement system, a module used for at least two hydraulically connected valve assemblies and The present invention relates to a method for electrically and mechanically connecting two non-conductive parts.

From the prior art, a sandwich arrangement system according to FIGS. 5 and 6 is known. In such a system, the valve assembly 102 is located on the serial connection plate 100 which replaces some of the single connection plates of the uncoupled valve. 5 and 6, the serial connection plate 100 has one pressure port 101P and one tank port 101T for all valve assemblies.
Only are provided. Ports 103a to 103f are arranged on the side surface of the serial connection plate toward the object to be used. The valve assembly 102 is, for example, a pressure, flow or non-return valve in the form of a sandwich plate,
A directional control valve is provided as the last element. Thus, the valves can be combined in a control circuit and the individual uses can be controlled.

With such a sandwich arrangement system, the installation work can be combined and the entire control circuit can be replaced or modified in a simple manner. In addition, space requirements are reduced and costs for hydraulic connections of single structural parts are reduced. In addition, correct assembly increases functional safety and facilitates troubleshooting over separate piped networks.

[0004] One disadvantage of this prior art sandwich arrangement system is the complicated electrical wiring. Each valve is connected to the control means via one or several cables, many of which appear laterally. Even if the cables are combined in the form of a cable harness or a ribbon cable, nevertheless a large volume is occupied by the different locations of the cable from the valve. In addition, wiring errors that result in damage to the valve can occur in cable harnesses and ribbon cables.

[0005] The problem of individual wiring of the valve is particularly pronounced when the valve is controlled via a memory programmed control system. Here, a command signal is supplied to the subordinate group control or the hierarchical control circuit by the main control. Group control then controls a single valve. Despite the use of cable harnesses or ribbon cables, confusing wiring of valves can increase the chance of error when adjacently arranged valve assemblies are controlled through group controls located at different locations. , Resulting.

A partial solution to this problem is disclosed in European Patent Specification EP 0 596 214. This patent specification relates to a solenoid operated hydraulic valve shown in FIG. 7, in which electromagnets 201, 202 are arranged on two sides of a base 203. A mounting plug 204 is provided on the base 203 between the electromagnets 201 and 202.
Is arranged. A mounting plug 204 is provided on the surface facing the electromagnets 201 and 202.
Includes plug contacts 204a, 204b, 204c, 204d into which the contact pins 201a, 201b attached to the electromagnet 201 or the contact pins 202a, 202b attached to the electromagnet 202 can be inserted, respectively. In addition, a cable for supplying current to the hydraulic valve
Subtracted from 4.

The solenoid operated hydraulic valve according to European Patent Specification EP 0 596 214 first places electromagnets 201, 202 in a position off the base 203, then applies a mounting plug 204 on the base 203, and finally 201 and 202 are moved toward the base 203, whereby the contact pins 201a, 201b,
202a, 202b are connected to plug contacts 204a, 204b, 204c, 204
It is assembled by engaging with d. Thus, an electrical connection between the hydraulic valve and the mounting piece is established. Only a single cable for the electromagnet, for example containing four electrical leads, is pulled on the hydraulic valve.

[0008] Similar solenoid operated hydraulic valves have the disadvantage that in the valve assembly one cable including one mounting piece is required for each solenoid operated valve. For a large number of control circuits on the serial connection plate in the sandwich arrangement system according to FIG. 5, multiplexing of the cables is required, which is detrimental to the clarity of the layout. Furthermore, there is a loss due to the length of the cable towards external control means, for example a memory programmed control system. Thus, while this solenoid-operated hydraulic valve avoids increasing space requirements due to the cables arranged beside the valve assembly, the problem of obtaining a plain layout of the electrical energy supply is: The multiplexing of centrally controlled valve assemblies has not been satisfactorily solved.

Accordingly, it is an object of the present invention to efficiently supply power to the electromagnets of the valve assembly, improve the clarity of the layout of the electrical connections to the hydraulic valves, and reduce the space requirements. A sandwich arrangement system including at least two valve assemblies, a height adapter for use with such a sandwich arrangement system, a module for use with at least two hydraulically connected valve assemblies to simplify the electrical connection of the valve assemblies And a method for electrically and mechanically connecting the two non-conducting parts, which can be implemented simply and in a short time.

The object is achieved by a sandwich arrangement system via the features of claim 1
This is achieved by a height adapter via the features of claim 13, by a module via the features of claim 14, and by a method via the features of claim 16.

At least two valve assemblies in number are arranged between the serial connection plate and the connection plate, the hydraulic connection of the valve assembly being achieved through the serial connection plate and the electrical connection being achieved through the connection plate. Is done. This reduces the cost of wiring compared to conventional sandwich arrangement systems, and the entire sandwich arrangement system is regarded as a hydraulic and electrical module that can be replaced at low cost.

The different heights of the valve assembly are compensated by a height adapter, whereby
Provides a safe electrical connection with the valve assembly.

[0013] In one embodiment, the connection plate extends parallel to the serial connection plate. Thus, the valve assembly including the height adapter has the same height,
This can provide a compact system that allows for different spatial orientations.

[0014] A mounting base may be provided on the connection plate, whereby, for example,
Hydraulic components of the valve assembly, such as pressure switches, can be electrically connected to the control circuit. Thus, the field of application of the sandwich arrangement system according to the invention can be expanded.

If the switching amplifier provided in the sandwich arrangement system is connected to the connection block, the sandwich arrangement system only needs to be supplied with low-voltage control signals which are processed by the switching amplifier. is there. Thus, it is possible to incorporate a sandwich arrangement system into a bus system.

[0016] The connection means of the sandwich arrangement system may establish an electrical connection. In another embodiment, the sandwich arrangement system is additionally coupled to control means, which may represent a memory programmed control system. Due to such an arrangement, a further part of the signal processing is performed directly in the sandwich arrangement system. As a result, the number of signals to be provided is reduced.

Control of the sandwich arrangement system can be performed, for example, via a personal computer, centralized control and / or memory programmed control system. Complex hydraulic processes are thus configured to be more easily controllable.

It is advantageous to connect the valve assembly to the height adapter or the connection plate via the valve mounting, respectively. These valve mounts support the modular structure of a sandwich arrangement system since different valve assemblies are provided with the same mounting surface.

The mechanical connection between the mounting, the height adapter and the connecting plate is preferably
It is realized by a latch or snap lock connection, which allows a simple assembly and disassembly of the sandwich arrangement system.

The electrical connections in the sandwich arrangement system are preferably made via mounting channels, height adapters and connection plates, which can be provided in the connection plates and connected in the assembled state. Thus, the external arrangement of the read is eliminated.

The plug-in members between the conductive channels facilitate the assembly of the sandwich arrangement system and ensure a reliable electrical connection.

In order to ensure sufficient electrical resistance between the individual conductive channels towards the individual valve assemblies, the mountings, height adapters and connecting plates are made of insulating material,
It is preferably made from plastic.

The height adapter for such a sandwich system fills the space between the valve assembly and the connecting plate, allowing for a mechanically stable configuration of the sandwich arrangement system. Height adapters having different structural heights can be used, thus allowing adaptation of different types of construction of the valve assembly.

A module for use with at least two hydraulically connected valve assemblies may be provided as a component for the electrical connection of the plurality of valve assemblies, where the components to a particular valve assembly are provided. Adaptation has been achieved with the help of a height adapter. Thus, a single module can be used for the electrical connection of the valve assembly, as well as using only one serial connection plate to establish a hydraulic connection.

In a method for mechanically and electrically connecting two non-conductive parts, a plug member is partially introduced into a channel of a first part, and a channel of a second part is set on the plug member. Later, a plug connection is established for the mechanical and electrical connection, while the latch connection serves only for the mechanical connection, so that a latch connection between the two parts is established. In this way, a connection can be established securely with the help of a minimum number of parts.

The connection method can be used for connection between the mounting portion and the height adapter, connection between the height adapter and the connection plate, and connection between the mounting portion and the connection plate. As a result, these components can be quickly connected to each other. Thus, the most varied form of the sandwich arrangement system can be produced in a short time.

Further developments of the invention form the subject of the dependent claims.

A sandwich arrangement system according to the present invention will be described with reference to FIGS.

FIG. 1 is a side view of a sandwich arrangement system according to the present invention, including a serial connection plate 1. This serial connection plate 1 should be understood as a plurality of connections of a single mounting sub-plate of the valve assembly, as described in connection with FIGS. 5 and 6, and the pressure port for the entire valve assembly 1
P and a tank port 1T are provided (FIG. 2). As in FIGS. 5 and 6, a port (not shown) directed to the object is located on the side of the serial connection plate. However, the ports intended for use may also be arranged at the required positions on the underside of the serial connection plate 1 of FIG.

On the upper side of the serial connection plate 1 in FIG. 1, a number of valve assemblies 2a, 2b, 2c, 2d, and 2e that are hydraulically controlled via the serial connection plate 1 are provided side by side and arranged in a row. Have been. The valve assembly is a functional unit where the flow, pressure, check and directional control valves are linked together in a sandwich plate design. Here, the valve disposed farthest from the serial connection plate is generally a directional control valve. As open-loop control systems for hydraulic uses require different types of functions and degrees of complexity, the valve assemblies 2a, 2b, 2c, 2d, 2e may have different numbers of functional units or / and nominal values. Present. As a result, the valve assemblies 2a, 2b, 2c, 2d, 2e arranged on the serial connection plate 1 have different structural heights. In the prior art, these different structural heights have proved to be obstacles to the efficient and plainly configured power supply of the valve assembly.

In the present invention, the mounting portions 3a, 3b, 3c, 3d, 3e, 3f are arranged on the valve assemblies 2a, 2b, 2c, 2d, 2e (FIGS. 1 and 2), 2f (FIG. 3). The attachments serve to supply current to electromagnets, such as 21f and 22f of the valve assembly 2f of FIG. 3, for example. To this end, with respect to electromagnet 22f, a conductive plug member 14, such as a circular connector, is partially received within a portion of electromagnet 22e, where plug member 14 is fixed to the electromagnet. , May be designed to be inserted into an electromagnet. The second electrical connection to the electromagnet 22f may be made at the mounting portion 3f and the electromagnet 22f by a plug member (not shown) similar to the plug member 14, or may be made by a central mass. Similar to the electromagnet 22f, a current is supplied to the electromagnet 21f via a similar plug member (not shown) in the mounting portion 3f.

For a better understanding of the invention, FIG. 3 shows a sectional view of a valve assembly 2f (not shown in FIG. 1) including two identical height adapters 4f and 4f ′. A valve assembly 2 f, which is a solenoid operated valve other than the valve assembly of FIG. 1, will be set directly on the serial connection plate 1.

The type of electrical connection in the valve assembly 2f described below may be provided in each of the valve assemblies 2a, 2b, 2c, 2d, 2e as well.

A part of the plug member 14 arranged outside the electromagnet 22f is connected to the channel portion 3 of the mounting portion 3f parallel to the serial connection plate 1 and laterally therefrom.
8f (compare FIG. 2). The channel portion 38f is coated with a conductive material such as copper, for example, and has a size such that the plug member 14 can be inserted with a small force. Around the plug member 14, for example, a seal 36f in the form of a seal ring is provided in a bridging region between the electromagnet 22f and the mounting portion 3f. Seal 36f serves to electrically insulate plug member 14 from the surroundings of the sandwich arrangement system.

In the direction perpendicular to the channel portion 38f, that is, in the direction perpendicular to the serial connection plate 1, the channel 37f which is conductive and is electrically connected to the channel portion 38f in the same manner as the channel portion 38f. Extending into the mounting 3f, where a conductive plug member 13 can be partially inserted to establish an electrical connection with the mounting 3f. Around the plug member 13, a seal member 35f similar to the seal member 36f can be incorporated into the attachment portion 3f.

The mounting portion 3f increases the distance between the electromagnets 21f and 22f, and subsequently the mounting portion 3f
By inserting f with the plug member, it is connected to the valve assembly 2f. Then, the distance between the electromagnets 21f and 22f is reduced again, and as a result, the mounting portion 3f including the electromagnets 21f and 22f is mechanically and electrically connected by the plug member.

The valve assemblies 2 a, 2 b, 2 c, 2 d, 2 e (FIGS. 1 and 2), 2 f (FIG. 3) are supplied with electrical energy via a connection plate 5. Depending on the structural height of the valve assembly, this connection plate 5 may either follow the mounting directly as in the case of the valve assemblies 2b, 2c in FIG.
, 2e or via two or more height adapters, as in the valve assembly 2f shown in FIG.

Within the height adapter 4f there is a conducting channel 47f, the lower end of which is shown in FIG. 3 receiving the other end of the plug member 13 and the upper end of which is shown in FIG. The part is provided with a part of the plug member 13 '. The plug member 13 ', like the plug members 13 and 14, has a sealing member 45 arranged in the height adapter 4f.
surrounded by f.

The height adapters 4a, 4d and 4e have the same structure as one of the height adapters 4f, 4f '.

For example, when there is no height adapter as in the case of the valve assembly 2b,
The electrical connection with the connection plate 5 is established via a plug member similar to the plug member 13 and, for example, when a height adapter is present as in the case of the valve assembly 2f, the electrical connection with the connection plate 5 Is established via the plug member 11.

The mechanical connection between the connection plate 5 and the mounting portions 3b, 3c, between the connection plate 5, the height adapters 4a, 4d, 4e, 4f, 4f 'and the mounting portions 3a, 3d, 3e, 3f respectively. Is made via a latch connection or a snap lock connection which is illustratively described with respect to the individually represented valve assembly 2f.

On the side of the mounting portion 3f in the lateral direction of the serial connection plate, latch concave portions 32f whose limits are determined by the latch protrusions 31f are arranged. A latch lever 41f aligned with the latch recess 32f is mounted below the height adapter 4f.

The mechanical and electrical connection of the mounting part 3f and the height adapter 4f will now be described.

First, the plug member 13 is partially inserted into the conduction channel 37f, and the seal member 35f is arranged around the plug member 13. Subsequently, the channel 47f is set on the plug member 13, and the latch lever 41f is aligned with the latch recess 32f. Then, a force is applied to the height adapter 4f from above as shown in FIG. 3, whereby the channel 47f is inserted into the plug member 13, and at the same time, the latch lever 41f enters the latch recess 32f and engages. Combine. As a result, the mounting portion 3f and the height adapter 4f are detachably connected to each other.

In order to release the latch connection between the latch lever 41f and the latch recess 32f, a force that pushes the latch lever 41f inward with respect to the mounting portion 3f requires:
It is added to the front part 40f of the latch lever 41f to release the engagement with the latch projection 31f. Subsequently, the height adapter 4f can be withdrawn along the plug member 13.

In addition, a support, preferably in the form of a seal ring, is arranged partially in the height adapter 4f in order to enable a secure mechanical connection between the mounting part 3f and the height adapter 4f. A member 44f may be provided between them. This support member 4
4f is made of an elastic member and ensures that the mounting part 3f is arranged on the height adapter 4f in a mechanically defined manner, even if there is a slight surface distortion.

However, either the seal member 35f or the support member 44f may be provided since the primary function of these two elements is to electrically insulate the pin from the surroundings of the valve assembly.

Similarly, a further height adapter 4f ′ and a height adapter 4f can be connected to each other with the help of a latching lever 41f ′ of the height adapter 4f ′ and a latching recess 42f of the height adapter 4f. . Guidance is obtained at the plug member 13 '. A support member 44f ', preferably in the form of a seal ring, may be provided between the height adapter 4f' and the height adapter 4f instead of or in addition to the seal member 45f. The connection plate 5 includes a plug member 11 and a latch lever 6.
1 with the help of a height adapter 4f '. In the connected state, the latch lever 61 is located in the latch recess 42f 'in the further height adapter 4f'. Around the plug member 11, a sealing member 45 'in the further height adapter 4f' and / or a support member 64 in the connection plate 5 may be provided.

When the height adapters 4 f and 4 f ′ are not provided, the latch lever 61
Are engaged in the latching recess 32f, and guidance is obtained along a plug member similar to the plug member 13. In this case, the support member 64 will contact the mounting portion 3f.

The connection plate 5 can be connected directly to an external control system such as, for example, a memory-programmed control system, a personal computer and / or a central controller, or can be connected to additional connection elements and / or in the vicinity May be present.

One option for connecting the additional connection element is to provide a mounting base 6 located on the connection plate 5 on the side opposite the valve assembly. On the lateral sides of the mounting base 6, the contact bushes 65, 66, as shown in FIG.
, 67, 68 may be provided.

According to the representations in FIGS. 1 and 2, the contact bush 65 is connected to the pressure switch 2 g via a connector 60 provided with a connection cable for providing an electrical connection. The pressure switch 2g is provided in the valve assembly 2a in the example of FIG.
It monitors the activation and deactivation of the electrical circuit as a function of the pressure. Contact bush 6
5, 66, 67, 68 may be connected to any electrical component, for example, an electrical actuation element that performs measurements in the hydraulic circuit or influences the hydraulic circuit. The function of the contact bush as an input or output bush is
It depends on the internal switch pattern of the contact bush in the mounting base 6.
One preferred variant consists in providing a specific number of input contact bushes and a specific number of output contact bushes in standard locations on the mounting base 6 as standard.

A switching amplifier 7 and control and connection means 8 are arranged side by side above the mounting base 6 in FIG. The control and connection means 8 comprises a memory programmed control system directed to the switching amplifier, as shown in FIG.
It can present a bus system, and a connector, and a connector that is directed directly to the valve. The switching amplifier 7 processes weak signals from the connector A for operation of the bus system, the memory programmed control system and the DC or AC solenoids of the valves of the valve assemblies 2a, 2b, 2c, 2d, 2e. The pressure switch 2g may be connected directly to a memory programmed control system in the control and connection means 8.

The length of the supply path is reduced as a result of the arrangement of the memory programmed control system and the switching amplifier near the valve assembly. The modular nature of the sandwich arrangement system is thus more asserted with regard to electrical operation.

The control and connection means 8 are connected in the example of FIG. 4 to an external memory programmed control system (MPC), wherein the internal bus system is the external MPC bus interface and the connector A is the digital The input / output circuit and connector B are connected to the power input and output. Coupling to the power input and output of the external MPC allows the valve assembly to be directly connected to the external MPC without the intermediate connection of a switching amplifier.

For example, the internal MPC can be connected to a personal computer and a central control system by a serial interface. External MPCs can also be conducted to the central control system.

However, the system configuration is not limited to the configuration of FIG. 4, but using the required configuration adapted to the particular application of the valve assembly as a switching amplifier, as control and connection means, and as external control means. Is also good.

[0058] The sandwich arrangement system according to the present invention is thus a pressure port and a tank port as hydraulic inputs, ports facing the use as hydraulic outputs, and as structural parts using digital signals as electrical inputs and outputs. Can be used.
The sandwich arrangement system can thus be operated both electrically and hydraulically, to a higher degree, as independent functional units, which can be supplied with an optimized amount of information through centralized control.

Thus, there is provided a sandwich arrangement system for at least two valve assemblies, the system comprising: a serial connection plate in which the valve assemblies are arranged side by side, whereby the valve assemblies are hydraulically connected; A connection plate through which an electrical connection with the electromagnet of the assembly is established. The valve assembly is preferably provided with a mounting, whereby an electrical connection with the connection plate is made. To compensate for height differences in the valve assembly, a height adapter is arranged between the mounting and the connection plate, thereby allowing a parallel arrangement of the serial connection plate and the connection plate. The electrical connection between the valve assembly and the connection plate is made in the mounting and height adapter with the aid of a plug member in the conductive channel. The connection plate can be connected to external control means via a switching amplifier and control and connection means.
