Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The invention according to claim 1, comprising a motor, a pump unit, an electronic control unit, and an electrical plug socket connector for electrically connecting the motor to the electronic control unit. The invention relates to a hydraulic device, in particular for an automotive slip-controlled hydraulic brake device.

Such a hydraulic device is known from the documents DE 197 56 729, EP 0 645 875 and EP 0 682 398. This hydraulic device basically consists of an electric motor, an electronic control unit and, in particular, a pump unit in between. In this case, the motor and the electronic control unit are connected to each other by a plug socket connector and are in electrical contact. In the case of the hydraulic device described in the unpublished German Patent Application 197 56 729, the plug-and-socket connector is guided through an opening in the pump unit. Alternatively, an electrical connection can be made outside the pump unit.

The disadvantage of these hydraulic devices known from the state of the art is that each plug-and-socket connector is formed relatively long, thereby requiring valuable large construction space. If the plug socket adapter of such a plug socket connector protrudes long, there is a danger that it will be inclined. The handling operation and the packaging of the hydraulic device are thereby further adversely affected by the plug-and-socket adapter projecting from the control unit.

The problem underlying the present invention is to improve a hydraulic device of the type mentioned at the outset so that the space required by the plug-and-socket connector is minimized.

[0005] In a hydraulic device of the type mentioned at the outset, this object is solved according to the invention by the features additionally described in the characterizing part of claim 1. According to this feature, the electrical plug socket connector comprises a plug formed as a coaxial conductor and a socket for accommodating the plug formed as a coaxial conductor. Such a plug and socket connector has the advantage that it requires very little space and is very simple to configure. The plug is coated with a synthetic resin, for example, in a tube around which a commercially available copper cable is wound to produce such a coaxial conductor. Since the socket can be formed in a very space-saving manner, there is the advantage that the entire plug socket connector can be accommodated in the valve block of the pump unit.

The plug is formed in a two-core shape, and the inner conductor of the plug formed as a coaxial conductor forms one core, and the outer conductor forms the other core. In the case of an embodiment of the plug-and-socket connector which is generally space-saving, it is advantageous if, for example, the supply voltage and the control voltage or the ground voltage can be guided from the electronic control unit to the motor.

[0007] Advantageously, at least part of the outside of the section of the inner conductor and / or the outer conductor provided for receiving in the socket is exposed.

It is particularly advantageous if the exposed sections of the inner conductor and the outer conductor of the plug are arranged offset from one another in the longitudinal direction. Thus, the socket can be easily formed. In this case, a good electrical contact is guaranteed.

It is advantageous if the insulating outer sheath around the outer conductor is formed conically at the transition to the exposed section of the outer conductor. This further reduces the overall plug and socket connector. The reason for this is that this conical section can be inserted approximately into the socket. Furthermore, good electrical insulation is obtained for components outside the plug.

[0010] Advantageously, the socket is formed by two parts, a first part containing the inner conductor of the plug and a second part containing the outer conductor of the plug. The two-part construction has the advantage that it allows a very simple manufacture of the socket.

[0011] Advantageously, the first and second socket parts are offset from one another in the longitudinal direction of the socket, and a part of the first socket part is inserted into the receptacle of the second socket part. This also further reduces the overall length of the plug and socket connector.

Advantageously, the plug or socket is integrated into the bottom plate of the electric motor and the plug or socket is housed in the valve block of the pump unit. Thereby,
The whole plug socket connector is formed very space-saving. This further positions the bottom plate of the motor radially with respect to the valve block by the corresponding counterpart in the valve block with the plug or socket.

Next, other effects and features of the present invention will be described in detail based on a preferred embodiment with reference to the accompanying drawings.

The terms “front side”, “rear side”, etc. used in the following description should not be construed as limiting, but serve only to make the description of the figures easier to read.

1 to 3 show a plug-and-socket connector (plug-in joint) 1 according to the invention with a plug 3 and a socket 3 from various directions. The plug socket connector or plug socket adapter 1 is generally provided between an electronic control unit, not shown, and a motor of a hydraulic device, also not shown, and usually projects slightly from the control unit. . Due to its small dimensions, the plug-and-socket connector 1 can be entirely accommodated, in particular, in the valve block of the pump unit.

For a general discussion of plug-and-socket connectors in hydraulic systems, reference is made to the unpublished German Patent Application 197 6729.0. The title of the invention of this application is "hydraulic device". By this reference, this application is incorporated herein in its entirety.

FIG. 4 is a sectional view of the plug and socket connector 1 according to the present invention in a state where the plug 2 and the socket 3 are fitted.

The plug 2 is formed like a coaxial conductor. For this purpose, one core of the plug socket connector 1 is assigned to the inner conductor 4 and the other core is assigned to the outer conductor 5 of the plug 2. The inner conductor 4 is surrounded by an inner synthetic resin extrusion coating or a synthetic resin coating 6. The outer conductor 5 is surrounded by an outer synthetic resin coating or a synthetic resin coating 7. FIG.
As shown in FIGS. 1 to 4, the inner conductor 4 is provided with a pin, a core rod and the like in the section 8 of the plug 2 for plug-in connection with the socket 3. At that time, the core rod may be formed integrally with the inner conductor 4 or may be a separate component that is conductively connected to the inner conductor 4.

The front end of the plug to be accommodated in the socket 3 is formed as follows.

The inner conductor 4 of the plug 2 has its front end exposed along section 8. For this reason, both the synthetic resin extruded covering portions 6 and 7 and the outer conductor 5 are not provided around the section 8. This section 8 is exposed during the production of the plug 2, especially afterwards. Section 9 is connected to section 8. The outer conductor 5 is exposed over the entire length of the section 9. That is, along this section 9, the outer synthetic resin extruded coating portion 7
Are not provided or have been removed later. The transition of the synthetic resin extrusion coating 7 from section 9 to a completely coated plug 2 takes place via a conical section 10 without being abrupt.

As can be seen in particular from FIG. 4, the socket 3 of the plug-and-socket connector 1 has two parts 11, 12. The first socket part 11 accommodates the exposed section 8 of the inner conductor 4 of the plug 2 and serves to make a conductive connection, and the second socket part 12
Serves to accommodate the exposed section 9 of the outer conductor 5 and to make a conductive connection.

For this purpose, the two socket parts 11, 12 are formed cylindrically and have central inner holes 13, 14 respectively. The diameter of the inner holes 13, 14 is somewhat larger than the outer diameter of the exposed sections 8, 9 of the plug 2. The exposed section is inserted into the inner holes 13 and 14 in a state where the plug socket connector 1 is assembled. On the open sides of the inner holes 13, 14, collars 15, 16 extending in the circumferential direction are formed on the inner side, respectively, to elastically accommodate the exposed sections 8, 9. The collar has an inner hole that opens in a funnel shape outward. When accommodating the exposed sections 8 and 9, respectively, only the inner portions of the collars 15 and 16 abut against the metal of the exposed sections 8 and 9. The socket 3 is particularly resiliently formed by a suitable choice of metal at the butt of the first and second socket parts 11,12.

The depths of the inner holes 13, 14 are respectively dimensioned such that the exposed sections 8, 9 are completely accommodated in the inner holes 13 or 14, respectively. Second socket part 12
In the same manner, a part of the conical section 10 of the outer synthetic resin extrusion coating 7 is inserted. In this case, the taper of the funnel-shaped inner hole of the collar 16 substantially corresponds to the taper of the conical section 10 of the outer synthetic resin extrusion coating 7.

At the end opposite the plug 2, a contact tab 17 or 18 projecting outward in the radial direction is attached to the outside of both socket portions 11, 12. This contact tab electrically connects the socket 3 to the plug 2 via the inner conductor 21 or the outer conductor 20 of the socket 3 and via an electrical connection with the inner conductor 4 or the outer conductor 5 of the plug 2. Help to do.

The front part of the first socket part 11 is in particular accommodated in a hole 19 on the rear side of the second socket part 12. The rear receiving hole 19 together with the inner hole 14 of the second socket part 12 can form a substantially through hole having a substantially constant diameter.

Since the length of the plug 2 according to the invention projecting from the electrical control unit is short,
This plug has no problem during packaging or handling operations of the hydraulic device and in particular of the control unit or in the inclined position of the plug 2. Furthermore, if the plug is accommodated in the valve block of the pump unit, a radial positioning of the bottom plate, especially including the socket 3, is ensured.

In some cases, the plug 2 and / or the socket 3 may be integrated with elements that affect the motor.
