Description

A SHIELDED CONNECTOR
The present invention relates to a shielded connector installed in a vehicle to prevent an electromagnetic wave from being emitted out of the vehicle. In more particular, the present invention relates to a shielded connector having an elastic member formed by cutting a portion of a conductive housing such that conductive housings coupled with each other are maintained in a conduction state.
Recently, as environmental pollution and global warming are accelerated, the restrictions against the exhaust fumes have been more enhanced in order to prevent the environmental pollution and global warming.
Accordingly, electric vehicles, which do not emit the exhaust fumes in driving, have been developed.
However, the electric vehicles must be equipped with an electrical battery to ensure a driving force instead of an internal combustion engine. However, since the electrical battery has a limitation in charge capacity, a driving distance is restricted. In addition, since the charging time of the battery is significantly required, many problems are caused in terms of convenience.
In order to overcome the problems of the electrical vehicles, hybrid vehicles equipped with both of the internal combustion engine and an electrical motor have been developed as an alternative.
The hybrid vehicle can use the internal combustion engine and the electric motor while frequently alternating the internal combustion engine and the electric motor if necessary. However, since the hybrid vehicle frequently changes a driving unit, a plurality of electric/electronic sub assemblies are required for the automation. To this end, various connectors are necessary to supply electricity or a control operation.
In particular, since the hybrid vehicle is driven by the electric motor, the hybrid vehicle uses a voltage significantly higher than a conventional internal combustion engine vehicle. Accordingly, the connectors generate strong electromagnetic wave.
The strong electromagnetic wave exerts an influence on an acoustic system to generate noise or causes a malfunction to the vehicle. In particular, if the vehicle is malfunctioned in driving, a very big accident such as sudden acceleration may occur.
Therefore, in order to prevent the damages, such as the malfunction of the vehicle or the noise generation of the acoustic system, caused by the electromagnetic wave, a shield connector has been developed to shield to electromagnetic wave generated from the connector.
As the shielded connector, a shielded connector to prevent short by allowing contact points to closely make contact with each other by an additional elastic unit is disclosed in Korea Unexamined Patent Publication No. 2010-86356.
According to the connector of the related art, an elastic member serving as an elastic unit is inserted between contact parts of metal housings making contact with each other, so that both metal housings are pressed by the elastic member while making contact with each other.
However, the connector must additionally include the elastic member for the purpose of the elastic contact of the metal housings, and the elastic member must be additionally installed between the metal housings. Accordingly, the productivity may be degraded.
In addition, since the elastic member has a very small size, it is difficult for a worker not only to grip the elastic member, but manage the elastic member. Accordingly, the elastic member may be easily lost in the working environment.

Still another object of the present invention is to provide a shielded connector in which a free end of an elastic member is located in an insertion direction so that the elastic member can be coupled with a conductive housing from the start point of coupling, thereby improving the reliability for the coupling.
Still another object of the present invention is to provide a shielded connector in which a free end of the elastic member is located in a direction opposite to the insertion direction, so the moment at a fixing end is gradually increased so that resistance is reduced upon the insertion of the elastic member, thereby facilitating the assembly work.
Still another object of the present invention is to provide a shielded connector capable of more improving the contact reliability by forming a protrusion on the surface of a free end of an elastic member making contact with a conductive housing.
Still another object of the present invention is to provide a shielded connector capable of more improving the contact reliability by forming a protrusion on the surface of a conductive housing making contact with a free end of an elastic member.

Hereinafter, a shielded connector according to exemplary embodiments of the present invention will be described in detail with reference to accompanying drawings.
Embodiment 1
A shielded connector according to a first embodiment of the present invention includes first and second assemblies 10 and 20 connected to each other as shown in FIGS. 1 to 3.
The first assembly 10 includes a first insulating housing 14, a first conductive housing formed at the outer portion of the first insulating housing 14, and a first terminal 18 formed in the first insulating housing 14.
The first insulating housing 14 includes resin that does not conduct electricity, and is provided therein with the first terminal 18. The first terminal 18 may be electrically connected to a second terminal 28 of the second assembly 20, which is described later, and an external device.
The first conductive housing 12 includes metal constituting an electrical conductor to absorb an electromagnetic wave generated from the inner part of the connector to shield the electromagnetic wave, so that the electromagnetic wave is not emitted to the outside. According to the present embodiment, although the first conductive housing 12 includes the alloy of aluminum (Al), the first conductive housing 12 may include another metal constituting an electrical conductor if necessary.
The second assembly 20 includes a second conductive housing 22 into which the first conductive housing 12 is inserted and a second terminal 28 provided in the second conductive housing 22 so that the second terminal 28 is electrically connected to the first terminal 18. The second terminal 28 is electrically connected to the first terminal 18 of the first assembly 10 and an external device.
The second conductive housing 22 includes metal constituting an electrical conductor so that the first conductive housing 12 is inserted into the second conductive housing 22 to allow electricity to be conducted. The second conductive housing 22 is conducted with the first conductive housing 12 to form a shielding circuit to absorb an electromagnetic wave generated from the inner part of the connector, thereby preventing the electromagnetic wave from being emitted to the outside. According to the present embodiment, although the second conductive housing 22 includes the alloy of Al, the second conductive housing 12 may include another metal constituting an electrical conductor if necessary.
In addition, the second conductive housing 22 has an elastic member 26 formed by cutting a portion of the second conductive housing 22. Since the elastic member 26 presses an outer surface of the first conductive housing 12 by the elasticity of the elastic member 26, when the first conductive housing 12 is inserted into the second conductive housing 22, the first conductive housing 12 is always conducted with the second conductive housing 22 to form a shielding circuit. In addition, the elastic member 26 is provided in the second conductive housing 22 exposed to the outside so that a person can check the connection state between the first and second housings 12 and 22 by a naked eye.
In addition, the elasticity member 26 has a fixing end 26a located in an insertion direction of the first assembly 10, and a free end 26b located in a direction to opposite to the insertion direction of the first assembly 10. Accordingly, as moment at the fixing end 26a is gradually improved, resistance is reduced when the first assembly 10 is coupled with the second assembly 20, so that the assembling work can be easily achieved. Further, in the elastic member 26, a protrusion 26c is formed on a surface of the free end 26b making contact with the first conductive housing 12. The protrusion 26c formed on the free end 26b allows the elastic member 26 to firmly make contact with the first conductive housing 12, so that contact reliability can be more improved. Since the reliability for the contact between the first and second conductive housings 12 and 22 can be improved, the spark can be prevented from being caused by the short at the contact point. In addition, a protrusion may be formed on the outer surface of the first conductive housing 12 making contact with the free end 26b of the elastic member 26. Even if the protrusion is formed on the outer surface of the first conductive housing 12 as described above, the contact reliability is improved similarly to when the protrusion 26c is formed on the free end 26b of the elastic member 26, so that contact reliability is improved. Accordingly the spark caused by the short can be prevented. Further, in the elastic member 26, in order to reduce stress at the fixing end 26a subject to the maximum moment to improve endurance of the elastic member 26, the width of the elastic member 26 is narrowed from the fixing end 26a to the free end 26b. In addition, perorations 26d are formed at both sides of the fixing end 26a to prevent stress from being concentrated.
According to the present embodiment, a coupling unit to couple the first assembly 10 with the second assembly 20 includes protrusions 12a formed at both lateral sides of the first conductive housing 12 and a rotational part 25 provided at lateral sides of the second conductive housing 22 and formed therein with slots 25a corresponding to the protrusions 12a. Therefore, the protrusions 12a of the first conductive housing 12 are fitted into the slots 25a of the rotational part 25. In the state that the protrusions 12a are fitted into the slots 25a, the protrusions 12a move along the slots 25a as the rotational part 25 is rotated. Simultaneously, the first and second assemblies 10 and 20 move in the axial direction in opposition to each other so that the first and second assemblies 10 and 20 are coupled with each other.
Embodiment 2
A shielded connector according to a second embodiment of the present invention includes the first assembly 10 and a second assembly 30 connected to each other as shown in FIGS. 4 to 6.
The first assembly 10 includes the first insulating housing 14, the first conductive housing 12 formed at the outer portion of the first insulating housing 14, and the first terminal 18 formed in the first insulating housing 14.
The first insulating housing 14 includes resin that does not conduct electricity, and is provided therein with the first terminal 18. The first terminal 18 is electrically connected to a second terminal 38 of the second assembly 30, which is to be described later, and an external device.
The first conductive housing 12 includes metal constituting an electrical conductor to absorb an electromagnetic wave generated from the inner part of the connector to shield the electromagnetic wave, so that the electromagnetic wave is not emitted to the outside. According to the present embodiment, although the first conductive housing 12 includes the alloy of Al, the first conductive housing 12 may include another metal constituting an electrical conductor if necessary.
The second assembly 30 includes a second conductive housing 32 into which the first conductive housing 12 is inserted. In this case, a terminal 38 is formed in the second conductive housing 32 so that the terminal 38 is insulated from the second conductive housing 32. The terminal 38 is electrically connected to the first terminal 18 of the first assembly 10 and an external device.
The second conductive housing 32 includes metal constituting an electrical conductor to absorb an electromagnetic wave generated from the inner part of the connector to shield the electromagnetic wave. According to the present embodiment, although the second conductive housing 32 includes the alloy of Al, the second conductive housing 32 may include another metal constituting an electrical conductor if necessary.
In addition, the second conductive housing 32 has an elastic member 36 formed by cutting a portion of the second conductive housing 32. Since the elastic member 36 presses an outer surface of the first conductive housing 12 by the elasticity of the elastic member 36, the first conductive housing 12 is always conducted with the second conductive housing 22 to form a shielding circuit. In addition, the elastic member 36 is provided in the second conductive housing 32 exposed to the outside so that a person can check the connection state between the first and second housings 12 and 32 by a naked eye. In addition, the elasticity member 36 includes a fixing end 36a located in a direction opposite to an insertion direction of the first assembly 10 and a free end 36b located in the insertion direction of the first assembly 10. Accordingly, since the elastic member 36 makes contact with the first conductive housing 12 from a time point when the insertion of the first conductive housing 12 is started, the reliability for the connection between the first and second assemblies 10 and 30 can be improved. Further, the elastic member 36 has a protrusion 36c are formed on a surface of the free end 36b making contact with the first conductive housing 12. The protrusion 36c formed on the free end 36b allows the elastic member 36 to firmly make contact with the first conductive housing 12, so that contact reliability can be more improved. In addition, a protrusion may be formed on the outer surface of the first conductive housing 12 making contact with the free end 36b of the elastic member 36. Even if the protrusion is formed on the outer surface of the first conductive housing 12 as described above, the contact reliability is improved similarly to when the protrusion 36c is formed on the free end 36b of the elastic member 36, so that contact reliability is improved. Accordingly, the spark can be prevented from being caused by the short. In addition, in order to reduce stress at the fixing end 36a subject to the maximum moment to improve endurance of the elastic member 36, the width of the elastic member 36 is preferably narrowed from the fixing end 36a to the free end 36b. In addition, perorations 36d are formed at both sides of the fixing end 36a to prevent stress from being concentrated.
According to the present embodiment, a coupling unit to couple the first assembly 10 with the second assembly 30 includes the protrusions 12a formed at both lateral sides of the first conductive housing 12 and a rotational part 35 provided on lateral sides of the second conductive housing 32 and formed therein with slots 35a corresponding to the protrusions 12a. Therefore, the protrusions 12a of the first conductive housing 12 are fitted into the slots 35a of the rotational part 35 and move along the slots 35a as the rotational part 35 is rotated in the state that the protrusions 12a are fitted into the slots 35a of the rotational part 35. Simultaneously, the first and second assemblies 10 and 30 move in an axial direction in opposition to each other, so that the first and second assemblies 10 and 30 are coupled with each other.
Embodiment 3
A shield connector according to a third embodiment of the present invention includes a first assembly 40 and a second assembly 50 connected to each other as shown in FIGS. 7 and 8.
The second assembly 50 is provided therein with a second conductive housing 52 into which a first conductive housing 42 of the first assembly 40, which is described later, is inserted. A second terminal 58 is formed in the second conductive housing 52 so that the second terminal 58 is insulated from the second conductive housing 52. The terminal 58 is electrically connected to a first terminal 48 of the first assembly 40, which is described later, and an external device.
The second conductive housing 52 includes metal constituting an electrical conductor to absorb an electromagnetic wave generated from an inner part of the connector to shield the electromagnetic wave. According to present embodiment, although the second conductive housing 52 includes the alloy of Al, the second conductive housing 52 may include another metal constituting the electrical conductor if necessary.
The first assembly 40 includes a first insulating housing 44, a first conductive housing 42 formed at the outer portion of the first insulating housing 44, and a first terminal 48 formed in the first insulating housing 44.
The first insulating housing 44 includes resin that does not conduct electricity and is provided therein with the first terminal 48. The first terminal 48 may be electrically connected to a second terminal 58 of the second assembly 50 and an external device.
The first conductive housing 42 includes metal constituting an electrical conductor to absorb the electromagnetic wave generated from the inner part of the shielded connector to shield the electromagnetic wave from being emitted out of the shielded conductor. According to the present embodiment, although the first conductive housing 42 includes the alloy of Al, the first conductive housing 42 may include another metal constituting an electrical conductor if necessary.
In addition, the first conductive housing 42 has an elastic member 46 formed by cutting a portion of the first conductive housing 42. Since the elastic member 46 presses an inner surface of the second conductive housing 52 by the elasticity of the elastic member 46, the first conductive housing 42 is always conducted with the second conductive housing 52 to form a shielding circuit. In addition, since the elastic member 46 is shielded from the outside by the second conductive housing 52, the inflow of foreign matters into the connector can be prevented. In addition, the elasticity member 46 has a fixing end 46a located in an insertion direction to the second assembly 50, and a free end 46b located in a direction opposite to the insertion direction to the second assembly 50. Therefore, as bending stress is gradually improved at the fixing end 46a subject to the maximum moment, resistance is reduced when the first and second assembly 40 and 50 are coupled with each other, so that the assembly work can be easily performed. Further, the elastic member 46 has a protrusion 46c are formed on a surface of the free end 46b making contact with the second conductive housing 52. The protrusion 46c formed on the free end 46b allows the elastic member 46 to firmly make contact with the second conductive housing 52, so that contact reliability can be more improved. Therefore, the spark can be prevented from being caused by the short at the contact point between the first and second conductive housings 42 and 52. As shown in FIG. 9, a protrusion 57 may be formed on an outer surface of the second conductive housing 52 making contact with the free end 46b of the elastic member 46. Even when the protrusion 57 is formed on the outer surface of the second conductive housing 52 as described above, the contact reliability can be improved so that the spark can be prevented from being caused by the short, similarly to when the protrusion 46c is formed on the free end 46b of the elastic member 46. In addition, in order to reduce bending stress at the fixing end 46a subject to the maximum moment to improve endurance of the elastic member 36, the width of the elastic member 46 is preferably narrowed from the fixing end 46a to the free end 46b.
According to the present embodiment, a coupling unit to couple the first assembly 40 with the second assembly 50 includes protrusions 42a formed at both lateral sides of the first conductive housing 42 and a rotational part 55 formed on lateral sides of the second conductive housing 52, and formed therein with slots 55a corresponding to the protrusions 42a. Therefore, the protrusions 42a of the first conductive housing 52 are fitted into the slots 55a of the rotational part 55 and move along the slots 55a as the rotational part 55 is rotated in the state that the protrusions 42a are fitted into the slots 55a of the rotational part 55. Simultaneously, the first and second assemblies 40 and 50 move in an axial direction in opposition to each other so that the first and second assemblies 40 and 50 are coupled with each other.
Embodiment 4
A shield connector according to a fourth embodiment of the present invention includes a first assembly 60 and a second assembly 50 connected to each other as shown in FIGS. 10 and 11.
The second assembly 50 is provided therein with the second conductive housing 52 into which a first conductive housing 62 of the first assembly 60, which is described later, is inserted. The second terminal 58 is formed in the second conductive housing 52 so that the second terminal 58 is insulated from the second conductive housing 52. The second terminal 58 is electrically connected to a first terminal 68 of the first assembly 60, which is described later, and an external device.
The second conductive housing 52 includes metal constituting an electrical conductor to absorb an electromagnetic wave generated from an inner part of the connector to shield the electromagnetic wave. According to present embodiment, although the second conductive housing 52 includes the alloy of Al, the second conductive housing 52 may include another metal constituting the electrical conductor if necessary.

The first conductive housing 62 includes metal constituting an electrical conductor to absorb the electromagnetic wave generated from the inner part of the shielded connector to shield the electromagnetic wave from being emitted out of the shielded conductor. According to the present embodiment, although the first conductive housing 62 includes the alloy of Al, the first conductive housing 62 may include another metal constituting an electrical conductor if necessary.
In addition, the first conductive housing 62 has an elastic member 66 formed by cutting a portion of the first conductive housing 62. Since the elastic member 66 presses an inner surface of the second conductive housing 52 by the elasticity of the elastic member 66, the first conductive housing 62 is always conducted with the second conductive housing 52 to form a shielding circuit. In addition, since the elastic member 66 is shielded from the outside by the second conductive housing 52, the inflow of foreign matters into the connector can be prevented. In addition, the elasticity member 66 has a fixing end 66a located in a direction opposite to a coupling direction with the second assembly 50, and a free end 66b located in the coupling direction of the second assembly 50. Accordingly, the free end 66b of the elastic member 66 is formed in the coupling direction between the first and second assemblies 60 and 50, so that the elastic member 66 is coupled with the second conductive housing 52 from a time point when the first and second assembles 60 and 50 are coupled with each other. Accordingly, the reliability for the coupling between the first and second assemblies 60 and 50 can be improved. Further, the elastic member 66 has a protrusion 66c formed on a surface of the free end 66b making contact with the second conductive housing 52. The protrusion 66c formed on the free end 66b allows the elastic member 66 to firmly make contact with the second conductive housing 52, so that contact reliability can be more improved. The spark can be prevented from being caused by the short at the contact point between the first and second conductive housings 62 and 52. In addition, in order to reduce stress at the fixing end 66a subject to the maximum moment, the width of the elastic member 66 is preferably narrowed from the fixing end 66a to the free end 66b.
According to the present embodiment, a coupling unit to couple the first assembly 60 with the second assembly 50 includes protrusions 62a formed at both lateral sides of the first conductive housing 62 and the rotational part 55 formed on lateral sides of the second conductive housing 52, and formed therein with slots 55a corresponding to the protrusions 62a. Therefore, the protrusions 62a of the first conductive housing 62 are fitted into the slots 55a of the rotational part 55 and move along the slots 55a as the rotational part 55 is rotated in the state that the protrusions 62a are fitted into the slots 55a of the rotational part 55. Simultaneously, the first and second assemblies 60 and 50 move in an axial direction in opposition to each other so that the first and second assemblies 40 and 50 are coupled with each other.
Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
As described above, according to the shielded connector of the present invention, as an additional elastic member is not provided, but the elastic member formed by cutting of a portion of the conductive housing is used, a process of additionally preparing an additional elastic member, and of installing the elastic member between conductive housings is not required, so that productivity can be improved.
