Description

[0001] ELECTRONIC CONTROL UNIT FOR VEHICLE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic control apparatus improved in the connection structure between a housing and a connector of an electronic control unit for a vehicle. More particularly, the present invention relates to an electronic control unit for a vehicle that improves fastening and waterproofing properties by curing a connecting portion between a housing and a connector of an electronic control unit using a liquid sealing material.

Generally, an electronic control device such as an ECU (Electronic Control Unit) that electronically controls various auxiliary devices is mounted on the vehicle. Such an electronic control device receives information from sensors or switches installed in various parts of the vehicle, processes information received from the sensors, or switches, and performs various electronic controls.

For example, an electronic control device such as an ECU, which controls the state of an engine, an automatic transmission, an ABS, and the like of a vehicle by a computer, controls all parts of the vehicle such as a drive system, a braking system, and a steering system as well as an automatic transmission control .

An electronic control device such as an ECU includes a housing formed of an upper cover and a lower base, a PCB (Printed Circuit Board) housed in the housing, and a connector for connection to an external socket or the like .

When the cover and the base are assembled together, the connector has a sealing portion for sealing the cover and the base. Thereby preventing external moisture or foreign matter from flowing into the housing.

Meanwhile, in the housing of the electronic control device, an electronic control element such as a PCB is inserted into the housing, and the electronic control element and the housing must be firmly fixed. Particularly, when a connector and a housing are to be connected and fixed, a sealing part is separately provided and fastened, thereby securing waterproof performance and fastening property. Generally, the sealing portion is inserted or fastened to the connection portion between the housing and the connector using an elastic member such as rubber.

However, if the elasticity of the sealing portion is reduced or damage is caused by external pressure or foreign matter, a clearance is generated at the connection portion, thereby reducing the fastening performance and the waterproofing performance, thereby hindering normal operation of the electronic control device .

In addition, the clearance and position between the housing and the connector can be changed little by little depending on the environment or use of the work. If a large number of separately manufactured sealing parts are used before the installation, the required fastening performance and waterproofing performance can not be obtained There is a problem.

Hereinafter, an electronic control device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention is not limited to the embodiments described herein, but may be embodied in various different forms. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

FIG. 1 is a perspective view of an electronic control apparatus according to the present invention, and FIG. 2 is a cross-sectional view taken along the line B-B 'of the electronic control apparatus shown in FIG.

The electronic control apparatus 10 according to the present invention includes an electronic control element 200 including a cylindrical housing 100 and a printed circuit board (PCB) inserted into the housing 100, And a connector 300 connected to the electronic control element 200. A sealing portion 900 is provided at the contact portion between the connector 300 and the housing 100 to prevent foreign matter such as moisture from entering and to secure the connection.

The housing 100 is provided in a box shape in which a hollow portion is formed to accommodate the electronic control element 200 therein, and the electronic control element 200 can be inserted through an opening thereof on one side.

In order to insert the electronic control element 200 such as the PCB, the housing 100 is provided so as to be opened and closed at one side and the other side is closed through a blocking member such as a back cover or selectively opened and closed . In addition, the shape of the housing 100 may be variously formed in a shape of a box, an integral shape, a side closed, and a hollow inside.

In the present invention, the sealing part 900 is provided in the connection part A between the housing 100 and the connector 300, and may be formed by applying a liquid sealing material and then curing.

The sealing portion 900 may be formed of a material such as rubber or synthetic resin and may be inserted into the sealing portion 900. The sealing portion 900 may be formed of a sealing material 900 of liquid material, And the connector 300 and curing the connector 300, the sealing effect and the fastening performance of the connector can be ensured.

That is, by using the sealing material 900 in a liquid phase, it can effectively penetrate into the clearance or gap between the housing 100 and the connector 300, and an excellent sealing effect can be obtained. Since the curing process is required after the sealing material 900 is injected, the sealing part may be formed by natural curing or by promoting the curing process in a dryer or a high temperature environment.

The liquid sealant (900) is a material that fills joints or joints between a building and an instrument device member. The liquid sealant (900) is used to secure airtightness and watertightness, Or a liquid rubber composition having a high viscosity such as the sealing material of the present invention. The liquid sealing material 900 may be injected into a site requiring sealing and fastening using a separate injection device (not shown).

The sealing material 900 may be used in a liquid state and may be a material having a viscosity of a predetermined size or more. In addition, when the temperature is increased, the viscosity is weakened. Therefore, when a sealing material having a high viscosity is used, the operation may be performed in a high temperature environment when injected into the connection part A between the housing 100 and the connector 300. That is, when the viscosity is low, it can penetrate well into the gap of the connection part (A) and can be hardened more firmly.

The housing 100 is divided into a first housing 110 in which the electronic control element 200 is embedded and a second housing 120 in which the connector 300 is connected to the first housing 100 . In one embodiment, the inlet size of the second housing 120 may be larger than the inlet size of the first housing 110. The connector 300 may be positioned within the second housing 120 so that the connector 300 may be protected.

A front portion of the connector 300 is divided into a front end portion of a connector and a plurality of outer pins 255 provided at a front end portion of the connector are connected to respective elements of the vehicle. The rear portion of the connector 300 is divided into a rear portion of the connector and a plurality of inner pins 250 are inserted into the housing 100 to be connected to the PCB 200.

A part of the connector 300 connecting the electronic control element 200 inserted into the housing 100 and the external vehicle side is accommodated in the first housing 110 and the connector 300 And the sealing member 900 is located at the connecting portion A of the first housing 120 and the second housing 120.

FIG. 3 is a cross-sectional view showing a cured state of the liquid sealing material 900 according to the present invention, and is an enlarged view of a connecting portion A of the housing 100 and the connector 300.

The second housing 120 is configured to have a width larger than that of the first housing 110 so that the first housing 110 and the second housing 120 can be connected to each other in a stepped manner.

The connector A may be provided with a protrusion 122 extending from the first housing 110 and one side of the connector 300 may be supported by the protrusion 122. [ At this time, a space is formed between the connector 300 and the second housing 120 without being in close contact with each other, and the liquid sealing material 900 is injected into the space.

A space 124 formed by the protrusion 122 and a part of the second housing 120 may be formed outside the protrusion 122. The liquid sealing material 900 may be injected into the space 124 to further enhance sealing and fixing between the connector 300 and the housing 100. [

A sealing portion is formed by inserting the connector 300 into the housing 100 and injecting a liquid sealing material 900 to seal the connecting portion and curing the sealing portion.

The sealing member 900 may have a sealing effect by fitting a separately manufactured sealing member to the connecting portion A. The shape of a portion where the inner peripheral surface of the housing 100 and the edge portions of the connector 300 are in contact with each other is referred to as a recessed portion And groove portions, or may be fabricated so that they can be assembled to fit with each other, such as half-fit.

According to the present invention, when the sealing material 900 is used as a liquid material, the effect of sealing and shielding is better than that of a structural fitting or a separately manufactured sealing material. That is, when the liquid sealing member 900 is cured by injecting the minute gap or clearance generated in the connecting portion A of the housing 100 and the connector 300, such a gap or clearance is sealed by the sealing member 900 It is possible to obtain an excellent moisture-proof and dustproof effect of the electronic control device.

A process of installing the electronic control unit using the sealing material 900 of liquid material will be described as follows. First, the electronic control element and the connector 300 are inserted through the opened one side surface of the housing 100, secondly, the connection portion A of the housing 100 and the connector 300 is tightly fitted, The connector 300 is provided so as to have the same contact area along the periphery thereof.

Third, in order to inject a liquid sealing material (sealant) into the connection portion A, an operator inserts the liquid sealing material 900 directly or uses a separate injector (not shown) to connect the housing 100 and the connector 300). Fourth, the drying environment is maintained so that the injected sealing material 900 is cured, and then the surface is checked for cracks or cracks after curing.

At this time, the shape of the connecting portion A may be provided with a protrusion, a latching portion, or a concave / convex portion so that the liquid sealing material 900 has a large contact area and can be hardened. The inner circumferential surface of the housing 100 is provided with a protruding portion protruding from the inner circumferential surface of the connector 300 along the rim of the connector 300, And can be manufactured in a form capable of receiving or engaging.

The shape of the end portion of the connector 300 may be variously modified. In order to increase the contact area with the sealing member 900, it is possible to form a concave or convex portion or a bent portion. That is, if the contact area is increased before the liquid sealing material 900 is cured, the contact performance and tightness of the sealing material 900 are improved.

That is, since the connecting portion A is a space generated between the end of the connector 300 and the inner circumferential surface of the housing 100, the shape of the end of the connector 300 and the shape of the inner circumferential surface of the housing 100 As described above, the protruding portion, the latching jaw, and the like are provided, and the contact area with the liquid sealing material 900 is increased, thereby improving the fastening performance.

In addition, when the sealing material 900 is solidified through hardening after being injected, protrusions are provided at the ends of the connector 300 to prevent the sealing material 900 from being detached from the outside, The shape of the connector 300 may be modified so that the diameter or the cross-sectional area of the sealing material 900 decreases from the inside to the outside of the housing 100.

4 is a cross-sectional perspective view showing a state in which the sealing member 900 is installed by enlarging the connecting portion A of the housing 100 and the connector 300. As shown in FIG. As shown in the drawing, the liquid sealing material 900 is injected into the connection portion between the housing 100 and the connector 300 and cured, thereby sealing the connection portion to improve the fastening performance and obtain a waterproof effect.

In order to inject the liquid sealing material 900, the operator may manually inject the liquid sealing material 900 through an injector (not shown), or may be injected while controlling the amount or time of injection by the automatic control device in order to work in a large amount.

Further, the liquid sealing material 900 may be sensitive to the working environment, especially the working temperature, so that the temperature during the operation may be controlled or the sealing material may be injected in a separate chamber.

When the sealing material 900 is injected into the connecting portion A and cured, the empty space (connecting portion, A) between the connector 300 and the housing 100 is filled up as shown in FIGS. 3 to 4, The surface of the connector 300 may be trimmed or the protrusion may be removed so that the exposed portion of the cured surface of the connector 900 and the surface of the connector 300 are uniformly provided.

That is, when the connecting portion and the exposed surface of the sealing material 900 and the connector 300 and the exposed surface are flattened and the adjacently connected portion is trimmed, the sealing material 900 can be firmly attached, It is possible to prevent foreign matter or moisture from flowing into the space.
