Description
Technical Field
The present invention relates to the field of vehicle connections and in particular, but not exclusively, to high power connections.
Background
When using cable connectors in high voltage/high strength applications, it is desirable to maintain cable-level shielding continuity through the cable connectors.
Furthermore, it may be desirable to prevent moisture, salt spray, dust, etc. from entering these cable connectors.

Detailed Description
In this document, the term "mating connector" generally and broadly designates any element intended to be electrically connected to a connector. Thus, it may be another connector, a housing on which the connection member is assembled, a wall through which electrical connection must be made, etc.
The same reference numbers will be used throughout the drawings to refer to the same or like elements.
Examples of embodiments of the connector assembly 1 are shown in fig. 1 to 3. Other embodiments of the connector assembly are contemplated, one of which will be disclosed below in connection with fig. 4 and 5.
The electrical connector assembly 1 of fig. 1 to 3 comprises a connector 2, a cable 100 and a shielding braid 200 (not shown in fig. 1 and 2). The connector 2 is configured for mating with a counterpart connector (not shown). Examples of the connector 2 include a mating assist system.
As shown in fig. 2, this example of the connector 2 includes an inner housing 3, an outer shield 4, a seal 5, an inner shield 6, a gear cam 7 (for a mating assist system), a CPA device 8 ("CPA" stands for connector position assurance (Connector Position Assurance)), an outer housing 9, a ring cap 10, a plastic cap 11, a shunt (shunt) 12 (for an interlock loop not shown), and a slider 13 (for a mating assist system).
The outer shielding 4 is formed as a single annular collar. The outer shielding means 4 is made of an electrically conductive material. The outer shielding 4 is made of metal. For example, it is a deep drawn piece, i.e. it is formed by a deep drawing process. Such deep drawn members have the advantage of providing seamless inner and outer surfaces. This ensures more flexibility in terms of the sealing material used in manufacturing and installing the sealing device 5.
The inner housing 3 and the outer housing 9 are made of an insulating material. For example, they are made of molded plastic. The inner housing 3 comprises at least one cavity (two cavities in the example shown in the figures). At least one conductive terminal is received in each cavity. Each cavity is located in a sealing area of the connector 2.
The inner shielding 6 is formed as an annular collar. The inner shielding 6 is made of an electrically conductive material. The inner shielding 6 is made of metal. The inner shield has flexible tabs 14 protruding on the outer surface of the annular collar forming the inner shield 6, the tabs 14 being configured to make electrical contact with the inner surface of the annular collar forming the outer shield 4.
The sealing means 5 is formed as a single annular collar made of elastomeric material. The sealing device 5 has at least two ribs 15a, 15b, each rib having a front rib 15a at a respective end of its longitudinal end (two or more ribs may be located at each longitudinal end.) at the front end of the sealing device 5 (i.e. near the mating interface of the connector). The rear rib 15b is located at the rear end of the sealing device 5 (i.e., to the cable side of the connector 2). Between the two ribs 15 the sealing means has a central strip 16 comprising an opening 17. Each opening 17 is configured to allow the sheet 14 to pass therethrough.
In the connector 2, the sealing means 5 is mounted between the inner shielding means 6 and the outer shielding means 4. The front rib 15a is in sealing contact with at least the inner surfaces of the outer housing 9 and the outer shielding 4. The rear rib 15b is in sealing contact with at least the inner surfaces of the inner housing 3 and the outer shielding 4. Thus, water tightness between the inner housing 3 and the outer housing 9 is provided by the outer shielding means 4 therebetween. In other words, a sealing barrier is formed by the outer housing 9, the front end of the sealing means 5, the outer shielding means 4, the rear end of the sealing means 5 and the inner housing 3.
Then, the shielding braid 200 may be mounted on the cable side of the connector 2 so as to make electrical contact with the outer surface of the outer shielding device 4. Advantageously, the shielding braid 200 is maintained on the outer shielding device 4 by means of the adhesive tape 19 or the tie 20. The tape 19 is wound around the outer case 9 and the shielding braid 200. The tape 19 is placed across the outer housing 9 and the shielding braid 200. The tie 20 sandwiches the adhesive tape 19, the braid 200, the outer shielding means 4, possibly the sealing means 5, the inner shielding means 6 and the inner housing 3.
Further examples of embodiments of the connector assembly 1 are shown in fig. 4 and 5.
As shown in fig. 5, the connector 2 includes a cap 21 for the outer shield 4, a cap 22 for the outer seal 23, the inner housing 3, an inner seal 24, the inner shield 6, and the outer housing 9 (mating assist elements not shown).
With the foregoing embodiment example, the outer shield 4 is formed as a single annular collar. The outer shielding means 4 is made of an electrically conductive material. The outer shielding 4 is made of metal. For example, it is a deep drawn piece, i.e. it is formed by a deep drawing process. Such deep drawn members have the advantage of providing seamless inner and outer surfaces. This ensures more flexibility in terms of the sealing material used in manufacturing and installing the sealing device 5.
With the foregoing embodiment example, the inner case 3 and the outer case 9 are made of an insulating material. For example, they are made of molded plastic. The inner housing 3 comprises at least one cavity (two cavities in the example shown in the figures). At least one conductive terminal is received in each cavity. Each cavity is located in a sealing area of the connector 2.
With the foregoing embodiment example, the inner shielding device 6 is formed as an annular collar. The inner shielding 6 is made of an electrically conductive material. The inner shielding 6 is made of metal. The inner shielding means has flexible tabs 14 protruding on the outer surface of the annular band forming the inner shielding means 6, these tabs 14 being configured to make electrical contact with the inner surface of the annular band forming the outer shielding means 4.
However, the sealing device of this embodiment is different from the sealing device of the foregoing embodiment. For this embodiment, the sealing means comprises two seals: an outer seal 23 and an inner seal 24. These outer seal 23 and inner seal 24 are, for example, seals of the O-ring type made of elastomeric material.
In the region extending longitudinally between the outer seal 23 and the inner seal 24, electrical contact is provided between the inner shielding means 6 (with the resilient tabs) and the inner surface of the outer shielding means 4. The inner seal 24 is in watertight contact with the inner surface of the outer shielding 4 and the inner housing 3. The cap 21 maintains the inner shielding 6 and the inner seal 24 in a position mounted on the inner housing 3. The outer seal 23 is in watertight contact with the outer surface of the outer shielding 4 and the outer housing 9. The cap 22 maintains the outer seal 23 in a position mounted on the outer housing 9. In other words, a sealing barrier is formed by the outer housing 9, the seal 23, the outer shielding 4, the seal 24 and the inner housing 3.
Then, the shielding braid 200 may be mounted on the cable side of the connector 2 so as to make electrical contact with the outer surface of the outer shielding device 4. Advantageously, the shielding braid 200 is maintained on the outer shielding device 4 by means of the adhesive tape 19 or the tie 20. The tape 19 is wound around a portion of the cap 22 and the shielding braid 200. The tape 19 is placed across the cap 22 and shielding braid 200 of this section. The ribbon 20 sandwiches the adhesive tape 19, the braid 200, the outer shield 4, the inner shield 6, and the inner housing 3.
In the disclosed embodiment, given by way of example, there is electrical continuity between the shielding braid 200 and the connector shields 4, 6 and a watertight area within the inner housing 3.
