Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the utility model, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

Example 1:

as shown in fig. 1, a shielded high-voltage connector housing includes a metal plug housing 100, a metal receptacle housing 300 and a plug shielding assembly 200, and when the metal plug housing 100 and the metal receptacle housing 300 are connected through the plug shielding assembly 200, a shielding line is effectively conducted.

Specifically, as shown in fig. 2, plug shield assembly 200 includes plastic shield cover 210 and shield spring 220, plastic shield cover 210 is inserted into metal plug housing 100, shield spring 220 is disposed in plastic shield cover 210, and one end of shield spring 220 abuts against metal plug housing 100. The plug shielding assembly 200 is inserted into the metal socket housing 300 under the driving of the metal plug housing 100, so that the other end of the shielding reed 220 abuts against the metal socket housing 300, thereby realizing the conduction of the shielding circuit after the butt joint of the connector plug and the socket, forming an electromagnetic shielding for the whole joint, and reducing the influence of an external electromagnetic field on a power supply or a communication line.

The plastic cover 210 includes a first cover ring 211 and a second cover ring 212 connected to each other at one side, the first cover ring 211 and the second cover ring 212 are sleeved to form a first space for the insertion of the shielding spring 220 therebetween. The shield spring 220 includes a first spring piece 221 and a second spring piece 222 having one end connected to each other, and the first spring piece 221 and the second spring piece 222 are stacked and form a second space for inserting the metal plug housing 100 therebetween.

Further, as shown in fig. 3 and 4, the first spring piece 221 includes an elastic mounting catch 2211 disposed away from the second spring piece 222. The first cover ring 211 is provided with a catch 2111 corresponding to the resilient mounting buckle 2211. After the shielding reed 220 is inserted into the first space of the plastic blocking cover 210, the shielding reed 220 is reliably connected with the plastic blocking cover 210 by the elastic mounting buckle 2211 and the clamping groove 2111, and the shielding reed 220 is prevented from falling off, so that the stability of the shielding circuit is improved. The resilient mounting buckle 2211 is preferably integrally formed with the first spring piece 221 to prevent the resilient mounting buckle 2211 from disengaging from the first spring piece 221.

More specifically, two elastic mounting buckles 2211 are arranged at the bottom of the first spring piece 221, and when the shielding reed 220 is loaded into the plastic blocking cover 210, the two elastic mounting buckles 2211 are elastically deformed by being pressed, and when the shielding reed 220 is loaded into the bottom of the plastic blocking cover 210, the elastic mounting buckles 2211 are bounced open and clamped in the corresponding clamping grooves 2111 of the first blocking cover ring 211.

As shown in fig. 5 and 6, the second spring piece 222 includes a plurality of elastic contact teeth 2221. The second cover ring 212 has through holes 2121 corresponding to the elastic contact teeth 2221. The resilient contact teeth 2221 pass through the through holes 2121 and abut against the metal jack housing 300 when the plug is inserted into the jack. Further, the size of the plastic blocking cover 210 is matched with the metal plug housing 100 and the metal socket housing 300, so that after the metal plug housing 100 is inserted into the metal socket housing 300, the tooth root 2221a of the elastic contact tooth 2221 abuts against the metal plug housing 100, and the tooth tip 2221b of the elastic contact tooth 2221 abuts against the metal socket housing 300, thereby realizing the stability of conducting the shielding circuit when the plug is connected with the socket. The resilient contact teeth 2221 and the second spring piece 222 are preferably integrally formed, so that the resilient contact teeth 2221 are prevented from being disengaged from the second spring piece 222.

More specifically, the second spring plate 222 is punched with a row of elastic contact teeth 2221, and the elastic contact teeth 2221 are divided into two portions, namely, a tooth root 2221a and a tooth top 2221 b. When the plug shield assembly 200 is connected to the metal plug housing 100, the tooth root 2221a is in surface contact with the metal plug housing 100, and due to the mutual pressing of the plastic shield cover 210 and the metal plug housing 100, a certain pressure is applied between the shield tooth root 2221a and the metal plug housing 100, so that the contact is reliable. At this time, the tooth top 2221b is suspended and has elasticity. When the plug shield assembly 200 is inserted into the metal receptacle housing 300, the suspended tooth tip 2221b contacts with the inner cavity of the metal receptacle housing 300 and is pressed by the inner cavity of the metal receptacle housing 300 to be elastically deformed, and after the insertion, the tooth root 2221a contacts with the surface of the metal plug housing 100 and the tooth tip 2221b contacts with the surface of the inner cavity of the metal receptacle housing 300 and is in an elastically deformed state, so that current can be reliably transmitted between the metal plug housing 100 and the metal receptacle housing 300.

Example 2:

a high-voltage connector adopts the shielding type high-voltage connector shell in embodiment 1, thereby realizing reliable contact of shielding reeds 220 with a metal plug shell 100 and a metal socket shell 300 through a plastic blocking cover 210 in a plug shielding assembly 200, ensuring effective conduction of a shielding circuit, and having simple structure and convenient assembly.
