Description
Technical Field
The present invention relates to a high-voltage shielded connector, and more particularly, to a high-voltage shielded connector having a shield for blocking electric interference such as electromagnetic waves when transmitting electric current and signals.
Background
As the number of electrical components used in a vehicle increases, the specific gravity for connecting the electrical components also increases. Connectors for electrical components are also classified into low-voltage and high-voltage connectors for use because various voltages ranging from low voltage to high voltage are supplied according to the use and function of the electrical components.
In the above connector, a cable through which a high current flows is connected to the high-voltage connector, but electromagnetic waves, noise, and the like are generated around the cable due to the high current. In order to block such electrical interference caused by electromagnetic waves, noise, and the like, a shield is provided inside the high-voltage connector.
Korean patent laid-open publication No. 10-1467722 (11/25 2014) discloses a high-voltage shielded connector.
The high-voltage shielded connector includes: a header connector provided to a panel of a vehicle; and a plug connector detachably coupled to the header connector.
Wherein, the bull-nose connector includes: a housing for forming the external shape of the header connector; an inner shell disposed inside the outer shell; the shielding piece is arranged between the outer shell and the inner shell; for blocking electrical interference.
The header connector is provided on a panel of a vehicle through a mounting hole, but since most of common mounting holes are rectangular extending in the right and left direction, the mounting portion of the header connector is also formed in the same rectangular shape.
However, as the external shape and structure of the vehicle are diversified, mounting holes of various shapes including a circular shape are formed in the panel of the vehicle, and thus a header connector having a mounting portion applicable to the mounting holes of various shapes is required.
On the other hand, a guide for installing the header connector and a ground finger for grounding are provided on the mounting portion of the header connector. In this case, since the guide and the ground fingers are alternately arranged along the circumference of the mounting portion, the section of the ground fingers exposed to the outside of the mounting portion is not wide enough, and thus there is a problem that the grounding efficiency with the panel is lowered when the header connector is provided.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein a detailed description thereof will be omitted when it is judged that a detailed description of related well-known technologies may unnecessarily obscure the gist of the present invention. Also, in the drawings, the same reference numerals are used to designate the same or similar structural elements.
The high-voltage shielding connector according to an embodiment of the present invention is a connector capable of blocking electrical interference such as electromagnetic waves when transmitting current and signals. The structure was observed as follows: the connector includes a header connector provided on a panel of a vehicle and a plug connector detachably coupled to the header connector.
As shown, the header connector 10 of the high-voltage shielded connector includes: a housing 100 for forming an outer shape of the header connector 10; an inner case 200 disposed inside the outer case 100; and a shield 300 disposed between the outer case 100 and the inner case 200.
The housing 100 includes a hollow body 110 extending in one direction. The front end of the body 110 is open to allow insertion and coupling of a mating connector, i.e., a plug connector (not shown). A guide unit 120 for guiding a coupling direction of the plug connector and a locking unit 130 for maintaining a coupled state with the plug connector are formed around the body 110. A receiving space 140 into which the plug connector is inserted is formed in the body 110, and an inner housing 200 and a shield 300 are provided in the receiving space 140.
A flange 150 that is in close contact with a panel (20 in fig. 4) of the vehicle when the header connector 10 is installed and an attachment 160 that penetrates the panel (20 in fig. 4) of the vehicle are formed at the rear end of the body 110. Annular attachment portions 170 and 320 to be inserted into and fixed to attachment holes 22 formed in a vehicle panel (20 in fig. 4) are formed around the attachment 160.
The mount 170, 320 includes: a guide 170 formed at the housing; and a ground 320 disposed at the shield 300.
On the other hand, fixing protrusions 190 for preventing the movement of the ground member 320 are formed at both sides of the guide member 170. The fixing protrusion 190 is formed with a snap-in groove 192 opened toward one side, and a snap-in plate 329 to be described later is inserted into the snap-in groove 192 when the shield 300 is provided.
The inner case 200 has a quadrangular tube shape similar to the outer case 100. A terminal (not shown) for transmitting current and signals is provided inside the inner case 200, and a shield 300 for blocking electrical interference such as electromagnetic waves is provided outside. In this case, the terminal is provided to the inner case 200 through the attachment 160 of the outer case 100.

The shield 300 includes: a body 310 bent in a tubular shape having a quadrangular cross section; and a ground member 320 provided at the rear of the body 310 and forming mounting portions 170 and 320 together with the guide member 170.
A lance 340 is formed at left and right sides of the body 310. The lances 340 are inserted into lance grooves (not shown) formed in an inner wall of the receiving space 140 to prevent the inserted shield 300 from being arbitrarily separated at the rear of the housing 300.
The pair of grounding members 320 is formed, and the pair of grounding members 320 are disposed to face each other around the attachment 160, that is, disposed on the left side and the right side of the attachment 160, respectively.
The ground member 320 includes: a first extension plate 322 protruding toward the rear of the body 310; a pair of second extension plates 324, 326 protruding from the first extension plate 322 toward the guide 170 side; and a plurality of ground fingers 328 protruding rearward from the first and second extension plates 322, 324, 326.
The grounding member 320 having the above-described structure is positioned between the pair of guides 170 to form the mounting portions 170 and 320, and has an increased interval exposed to the outside of the mounting portions 170 and 320 compared to the conventional art, thereby having excellent contact with the panel 20. Thereby improving the grounding efficiency between the grounding member 320 and the panel 20.
On the one hand, at the end of the ground member 320, in more detail, at the end of the second extension plates 324 and 326, a snap-in plate 329 inserted and fixed to the snap-in groove 192 is formed. The snap-in plate 192 is fixed to the fixing protrusion 190 to limit the deformation of the second extension plates 324 and 326, so that the second extension plates 324 and 326 and the ground fingers 328 have constant elasticity. Therefore, not only the grounding efficiency between the grounding member 320 and the panel 20 can be further improved, but also the header connector 10 can be accurately and stably provided to the panel 20.
On the other hand, an annular insertion groove 180 is formed around the mounting portions 170 and 320, and the seal ring 30 is inserted into the insertion groove 180. The seal ring 30 is inserted into the insertion groove 180 to prevent foreign matter such as moisture from flowing into between the header connector 10 and the panel 20.
As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited to the embodiments and drawings disclosed in the present specification, and it is apparent that those skilled in the art to which the present invention pertains can implement various modifications of the present invention within the scope of the technical idea of the present invention.
