Description

Technical Field [0001] The present invention relates to a connector assembly and a connection system using the connector assembly.

The present invention relates to a connector assembly.

The electrical control device is typically connected to the wiring harness by one or a plurality of electrical connectors. To enable such electrical connection, it is common to provide a connector assembly (also referred to as a socket) in the housing of the electrical control device.

Also, signals or power through these connectors may cause electromagnetic interference (also known as "EMI") or the signal or power itself may cause disturbance. Therefore, it is advantageous to shield the signal or power passing through such a connector in order to increase the immunity to the incoming interference and reduce the degree of disturbance generated. These measures are also referred to as "EMC" or electromagnetic compatibility.

It is an object of the present invention to improve the shielding property of the connector assembly.

According to the present invention, there is provided a connector assembly configured to be fastened to a mounting support, for example, an electric control device, and adapted to receive a mating counterpart belonging to a wiring harness.

The connector assembly includes a connector foot configured to be fastened to the housing of the electrical control device by a fastening device.

The connector foot portion includes a base metal shielding plate.

According to the present invention, the shielding plate is made of any electrically conductive material such as copper alloy, tin, and aluminum alloy, which are classified in different categories (or series) according to major alloy elements.

In addition, such connector assemblies can be exposed to the external environment, so that various types of corrosion (such as pitting corrosion or surface corrosion) can occur, which may affect the function of the connector assembly. Therefore, it is of interest to provide a connector assembly that exhibits good shielding properties and is resistant to humid and corrosive environments.

For this reason, according to one embodiment, the metal shield plate is made of an aluminum alloy of 1XXX series such as 1100, 1080, 1050, 1060, 1070, or 1010. Indeed, the specific 1XXX series of aluminum alloys employed in this application exhibit corrosion protection and shielding properties.

According to a preferred embodiment, the metal shielding plate is made of aluminum alloy 1050.

The classification of aluminum alloys is established by the International Alloy Designation System (IADS), which is well known to those skilled in the art.

According to the IADS, the 1XXX series aluminum alloy contains at least 99% aluminum. The second digit represents the change to the alloy or impurity limit, and the last two digits represent the purity of the alloy. For example, aluminum alloy 1070 means at least 99.70% aluminum, aluminum alloy 1050 means at least 99.50% aluminum, aluminum alloy 1100 contains at least 99.00% aluminum .

The connector may further include a body portion extending from the connector foot portion to the mounting support in an outward direction.

In a preferred embodiment, the connector body portion has a body shielding member electrically connected to the metal shielding plate. In addition, the metal shield plate is electrically continuous with the fastening device.

This arrangement ensures electrical continuity between the fastening device and the body shielding member each time the connector assembly is fastened to the mounting support. The fastening device is also in electrical connection with the mounting support to establish complete electrical continuity between the mounting support and the body shielding member of the connector assembly.

In some other embodiments, one or more features as defined in the dependent claims may be utilized.

According to another aspect, the present invention also relates to a connection system comprising a connector assembly, a fastening device, and a mounting support as described above. Further, the fastening device is configured to fasten the connector assembly on the mounting support, and the fastening device is electrically connected to the mounting support.

According to another aspect, the present invention also relates to a method of assembly for fastening a connector assembly as described above to a mounting support,

Mounting a metal shielding plate on the connector foot,

Inserting a metal insert into the hole, and

And fastening the connector assembly by a fastening device.

As a result, the shielding member is electrically connected to the metal shielding plate, and the metal shielding plate is electrically continuous with the tightening device. Further, the fastening device is electrically continuous with the mounting support.

Other features and advantages of the present invention will become apparent from the following detailed description of one of the embodiments given by way of non-limiting example and with reference to the accompanying drawings.
In the figure,
1A and 1B are general views of a connector assembly according to the invention,
2 is a cross-sectional view of the connector assembly of FIG. 1,
3 is an enlarged view showing in detail the cross section of the foot.

In the drawings, the same reference numerals denote similar or identical elements.

- a connector body portion (2) extending from an upper surface (16) of the connector foot portion and having a generally cylindrical general shape.

The connector foot portion 1 and the connector body portion 2 may be formed of a plastic part, preferably an integral plastic molded part.

In the illustrated example, the connector body portion 2 has an elliptical shape with an outer surface 25 and an inner surface 26 (see FIG. 2). A body shield member 22 is positioned adjacent the inner surface 26 and the body shield member 22 is formed of a thin metal sheet extending from the base portion 22a to the top portion 22b. The base portion 22a is adjacent to the lower surface 15 of the connector foot portion 1. [

A hollow portion 80 in which the wire and the terminal can be positioned is provided in the inward direction with respect to the body shield member 22. [ In the illustrated example, two power connection portions 81 and 82 and two signal connection portions 83 and 84 are provided in the hollow portion 80 (see also Fig. 1B). Of course, other connection configurations may be possible.

The matching connector belonging to the wiring harness can be connected to the connector assembly 10 along the mating axis X from the left side in Figs. 1A and 1B.

The body shield member 22 has an elastic lug 23 extending obliquely outwardly from the base portion 22a. In the illustrated example, the elastic lugs 23 are disposed all around the base 22a. The elastic lugs 23 are in contact with the base metal shielding plate 3 to achieve an electrical connection between the body shielding member 22 and the metal shielding plate 3.

As can be seen from Fig. 2, the connector foot 1 is configured to be fastened to a mounting support, such as the housing 6 of the electrical control device, by fastening means. The electrical control device has an electrical interface with a power source, for example via a sensor and an actuator, and an electrical connector assembly, such as the connector assembly 10 shown in view. The connector foot portion may be directly fastened to the vehicle frame portion or the engine portion rather than the electric control device.

The housing 6 surrounds the control unit and is configured to mechanically and electromagnetically protect the control unit. The housing (6) includes a recess (60) configured to receive a fastening device (5). In the illustrated example, the fastening device is a screw 50 and its mating part is a threaded hole 60, but other fastening devices such as riveting, press fit or other means are included within the scope of the present invention.

At least around the threaded hole 60, the housing 6 is partly metal and the fastening device 5 is permanently electrically connected to the housing 6 when fastened to the housing.

On the connector foot portion 1, at least a hole 14 for receiving the fastening device 5 is provided. In the example shown above, four holes 14 are provided at four corners of the foot portion 1.

Also, the metal insert 4 is inserted into each hole 14. Each metal insert 4 is electrically connected to both the metal shielding plate 3 and the fastening device 5, which will be described in detail below.

The base metal shielding plate 3 has a rectangular shape of the foot 1 arranged parallel to the interface P perpendicular to the mating axis X when the base metal shielding plate 3 is returned to the base metal shielding plate 3. [ And is formed of a thin metal sheet having a substantially rectangular shape similar to that of the metal sheet.

The base metal shielding plate 3 has a central opening 30 for the electrical connection path and a hole 44 coaxially positioned with respect to the hole 14 of the connector foot 1 The hole of each of the holes 44 at least includes an inclined elastic protrusion 33 extending toward the foot portion 1 and adapted to be brought into contact with the metal insert 4. In addition, the base metal shielding plate 3 includes four clips 32 (see FIG. 1A) that engage the corresponding reset 18 provided on the connector foot. The clip 32 extends substantially perpendicularly from the surface of the shielding plate 3. Preferably, the clip 32 has a pine shape such that it is retained when inserted into the recess 18, and the metal shielding plate 3 is secured to the fastening device 5 prior to engagement with the fastening device 5, And is firmly held on the foot portion 1.

Permanent electrical connection is achieved between the housing 6 and the body shielding member 22 via the metal shielding plate 3 and the metal insert 4 as a result of the assembly described above being fastened to the housing 6. [ Therefore, with the advantage of the present invention, shielding continuity is provided between the housing 6 and the connector body portion 2, thereby enabling improved electromagnetic protection for both the control unit itself and the electromagnetic environment. Accordingly, any kind of suitable treatment, such as painting, corrosion protection, etc., which can be electrically insulated on the outer surface of the housing 6, is provided.

3, an example of the tightening device includes a screw 50 having a head 52, a bearing collar 51, a body (not shown) having a male screw 54 housed in a female screw 60 of the housing 6 53). The metal insert 4 includes a lower section 41 in contact with the resilient protrusion 33 and an upper section 42 in contact with the collar 51 of the screw.

The outer surface of the metal insert is adjacent to the inner surface of the hole (14). A border 17 is provided in the upper region of the hole 14 and protrudes along the mating axis X to the upper edge 42b of the upper section 42. [

A local cut-away view on the left side of the screw of Fig. 3 shows the pre-screw-joined border 17 while the right side shows the post-screw-joined border 17. Fig.

As a result, when the screw 50 is screw-engaged, the border 17 first reaches the collar 51 and then reaches the upper edge 42b of the upper section 42 of the metal insert 4 Downward to the extent specified by < / RTI >

Thus, the compressed portion, at least partially and resiliently deformed, acts as a brake against the screw 50 to prevent unwinding of the screw 50.

The present invention also relates to an assembly method for assembling the connector assembly 10 to the housing 6 as described above,

- mounting said metal shielding plate (3) to connector foot part (1), keeping metal shielding plate (3) in place by clip (32) as described above,

- inserting the metal insert (4) into the hole (14), and

- fastening the connector assembly by fastening device (5).

As a result, the body shielding member 22 is permanently electrically connected to the metal shielding plate 3, the metal shielding plate 3 is permanently electrically continuous with the tightening device 5, And is permanently electrically continuous with the housing (6) through the metal insert (4).

Therefore, the electrical continuity and the shielding continuity from the connector body 2 to the electrical control apparatus housing 6 are ensured.

In addition, the screw 50 compresses the borders 17 at the time of screw-engagement, and the compressed borders at least partly and elastically deformed brakes the screw after screw-engagement to release the screw 50 .

example

Example 1: Salt spray test for connection system
