Definitions
- the present invention relates to a housing for a control unit and in particular to a housing with a ventilation channel for a brake control unit.
- Control devices and in particular those used in commercial vehicles have to ensure a reliable sealing of the housing, even during constantly changing external influences (temperature fluctuations,
- a known problem is, for example, that in a housing with a cover and a bottom plate when connecting the two components, an overpressure is generated in the housing. This occurs in particular when the bottom plate is placed on the lid and an air-tight connection is to be made
- Temperature fluctuations In vehicles, for example, temperature variations of -40 ° C up to 85 ° C or more can occur at the positions of the control units, which lead to pressure fluctuations that have to endure the control units to ensure reliable operation.
- pressure compensation elements are used for this purpose.
- These pressure equalizing elements include, for example, a diaphragm that deforms at a pressure differential and, for example, allows diffusion to produce a gradual pressure equalization.
- the pressure compensation elements are additional components that make the structure of the controllers more complicated and can also form an additional source of error. But they also make it difficult to manufacture the control units.
- the present invention relates to a housing suitable for a control unit.
- the housing includes a lid, a bottom member that is sealed to the lid, and a closable opening to allow venting during assembly of the housing.
- the opening may be located at any location, for example in the lid or in the bottom plate.
- the housing further comprises an electrical connection for a connection cable, wherein the opening in a bottom region of the electrical connection is designed such that after insertion of the electrical connection cable, the connection cable closes the closable opening.
- the housing comprises a closure element for the closable opening, wherein the closure element is designed to close the housing interior tight.
- the closure member may comprise a plug which is insertable into the opening and closes it.
- the closure element however, it may be any element capable of closing (or opening) the opening. For example, it may also include a flap or slider. Even the connection cable itself can act as a closure element, if it closes the opening sufficiently.
- the opening includes a first portion and a second portion, the first portion having a diameter that is greater than the diameter of the second portion.
- the plug may have a first portion and a second portion, wherein the first portion has a larger diameter than the second portion and is insertable in the first portion. The second portion is insertable into the second portion, so that after insertion of the plug into the opening, the plug can be inserted only up to a predetermined depth, thereby improving the sealing effect.
- a tight adhesive connection is formed between the cover and the bottom element, so that the interior of the housing is watertight sealed from an environment.
- the present invention also relates to brake control apparatus (e.g.
- the present invention further relates to a commercial vehicle with the brake control device.
- the present invention further relates to a method for venting a housing of a control device during assembly.
- the method comprises the steps of providing a lid and a floor element, wherein the lid or the floor element has an opening.
- the method further includes connecting the lid and the floor member while the opening provides venting, and closing the opening to achieve sealing of the housing.
- the method may optionally include a leak test in which first a pressure differential is formed between an interior of the housing and an environment utilizing the opening. Subsequently, the tightness of the Be determined housing based on a time measurement and the formed pressure difference (eg detection of a time decay behavior of the pressure).
- a leak test in which first a pressure differential is formed between an interior of the housing and an environment utilizing the opening. Subsequently, the tightness of the Be determined housing based on a time measurement and the formed pressure difference (eg detection of a time decay behavior of the pressure).
- the opening may be formed in a bottom portion of an electrical terminal of the controller, and the method may optionally include closing the opening by inserting a plug into the opening and connecting a terminal cable to the electrical terminal.
- the connection cable blocks a removal of the inserted plug.
- FIG. 1 shows a housing for a control device according to an embodiment of the present invention.
- FIGS. 2A, B show further details of the housing with inserted plug according to a further embodiment.
- 3A, B show an embodiment of the housing without a plug.
- Fig. 1 shows a housing, according to an embodiment of the present invention.
- the housing is for a control unit in a vehicle, in particular in a
- a cover 1 10 e.g, a bottom member 120 (eg, a bottom plate) and a closable opening 130 to allow venting during assembly of the housing.
- the lid 1 10 and the bottom member 120 are tightly connected (eg, waterproof or airtight). Is to For example, a groove formed in the bottom member 120, in which an end portion of the lid 1 10 is used and are connected by an exemplary seal (eg by an adhesive) tightly together.
- the controller may be any controller, but in particular a
- Brake control unit should be included.
- Fig. 2A shows further details of the housing, which in different
- the groove 1 15 is formed in the lid 1 10 and in the groove 1 15 an exemplary adhesive bond is formed to a reliable
- the housing can be various
- a circuit board 160 is shown, which is electrically contacted via a connecting cable 170.
- the closable opening 130 is as a
- the opening 130 may, for example, be formed as part of the electrical connection 150, wherein the electrical connection 150 may represent a connection socket (or socket) for the connection cable 170.
- the opening 130 may be located in a bottom area and be closable via a plug 180.
- Fig. 2B shows an enlarged view of the area A of the housing, in which the opening 130 is formed with plug 180.
- the plug 180 may be inserted into the port 130 prior to insertion of the connection cable 170 into the junction box 150.
- the plug 180 may, for example, be conical or step-shaped, so that the plug 180 can only be inserted to a certain depth within the opening 130. Slipping out of the plug 130 is after the
- connection cable 170 prevented.
- the plug 180 due to its shape itself and / or due to the shape of the opening 130, can not get into the interior of the housing.
- connection cable 170 in the electrical connection 150 but also for example via a clamping or screw connection or other forms of locking
- the Plug 180 is held under a bias in the opening 130 and thus closes tightly and remains closed.
- the plug 180 includes, for example, a thinner portion 182 located in a lower region of the opening 130 (area with the lower one)
- the plug 180 includes annular protrusions formed in that portion of the plug 180 that faces after insertion to the exterior of the housing.
- the annular projections are formed, for example, slightly larger than a cross-sectional area of the wider portion of the opening 130, so that the plug 180 by applying a
- Minimum force is pressed into the opening 130, so as to ensure a reliable tightness.
- the closable opening 130 may be open (the plug 180 is not yet inserted). Therefore, the opening 130 provides venting and prevents any pressure differential with the environment from being manifested during assembly, even when the adhesive joint 140 airtightly joins the bottom member 120 to the lid 110. The resulting overpressure during assembly of the bottom element 120 with the cover 1 10 can be derived immediately via the vent passage 130.
- the housing is hermetically sealed by closing the opening 130 of the housing via the plug 180 (e.g., a blind plug). Reliable positioning of the blanking plug 180 can be said to do so
- the opening 130 for example, as part of a
- Socket 150 is provided so that after attaching the wiring 170, the plug 180 is blocked and the opening 130 can not leave.
- Using a blind plug 180 offers the advantage of being cost effective
- the placement of the opening 130 as part of an electrical connection 150 is a safe way to after a latching of a
- exemplary harness connector also the security of the positioning of the dummy plug is ensured.
- Fig. 3A shows an embodiment of the housing in which the opening 130 is not closed by a plug 180. Although the closeable opening 130 still provides a vent passage during assembly, the closure is accomplished solely by the connection cable 170.
- FIG. 3B shows an enlarged view of the region B of the housing in which the opening 130 without plug 180 is formed. In the shown
- the opening 130 is step-shaped and comprises a first section 131 with a larger cross-sectional area and a second section 312 with a smaller cross-sectional area, wherein the first section 131 with the larger cross-sectional area is in the area in which the
- Connecting cable 170 is inserted in the junction box 150.
- the step-shaped cross-sectional configuration of the opening 130 thus makes it possible for the previously described plug 180, which may also be step-shaped, to be placed in the opening 130 and to reliably close the opening 130 in the step.
- the connection cable 170 can also provide a reliable seal, the optional plug 180 need not be deployed (as in Figs. 3A, 3B).
- a pressure difference to the environment can be produced in a targeted manner. If the pressure difference is maintained for a certain period of time (by itself), this indicates that the housing is sufficiently dense. It is also possible to determine the tightness based on a time measurement (to reach the pressure difference or a subsequent pressure drop).
- a further advantage of embodiments is that, in contrast to conventional housings, no pressure compensation elements are necessary because the opening 130 to allow venting during assembly.
- a pressure equalization during operation (for example, as a result of temperature fluctuations) can be achieved for example via a deformation of the bottom element 120.
- connection cable 180 plug
