Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an electric connector shielding cover. Background Art

[0002] Electronic connectors are also often called circuit connectors, electrical connectors, and conductor devices that bridge two conductors in a loop so that current or signals can flow from one conductor to another. An electronic connector is an electrical system that provides a separable interface for connecting two sub-electronic systems. Simply put, the component used to complete the electrical connection between circuits or electronic machines is called a connector, which is the bridge between the two.

[0003] The electrical connector shielding cover can protect the internal electrical connector from external interference and keep the electrical connector running stably. However, once the existing electrical connector shielding cover is installed on the electrical connector, it takes a long time and is inconvenient to replace it once it is damaged. Therefore, an electrical connector shielding cover is proposed. Summary of the invention

[0010] Preferably, a spring is fixedly connected to one side of the pressure plate, one end of the spring is fixedly connected to the second shielding cover, a fixing bolt is threadedly connected in the threaded hole, and limiting plates are fixedly connected to both sides of the bottom shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the device is in use, the fixing bolts in the threaded holes can be removed to separate the first connecting plate from the second connecting plate and the third connecting plate. One end of the pressing plate is pressed, the spring contracts, and the pressing plate slides along the surface of the sliding rod. The pressed end of the pressing plate is close to the second shielding cover, and the other end of the pressing plate is tilted and leaves the rectangular groove and moves away from the first shielding cover, so that the first shielding cover and the second shielding cover can be separated. The utility model has a simple structure and takes less time and is more convenient when the shielding cover needs to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-Figure 4, an electrical connector shielding cover, including a rectangular bottom shell 1, a first connecting plate 2 is fixedly connected to the top of the bottom shell 1, and a second connecting plate 3 and a third connecting plate 4 are slidably connected to the top of the first connecting plate 2.

[0020] Furthermore, a first shielding cover 5 is fixedly connected to the top of the second connecting plate 3 , a second shielding cover 6 is fixedly connected to the top of the third connecting plate 4 , and threaded holes 7 are provided on the first connecting plate 2 , the second connecting plate 3 , and the third connecting plate 4 .

[0021] When the shielding cover needs to be disassembled, the fixing bolts in the threaded holes 7 are removed, and the first connecting plate 2 is separated from the second connecting plate 3 and the third connecting plate 4, thereby separating the first shielding cover 5 from the second shielding cover 6.

[0022] Furthermore, a limiting groove 8 is provided on one side of the first shielding cover 5 and the second connecting plate 3 , a limiting block 9 is fixedly connected to one side of the second shielding cover 6 and the third connecting plate 4 , and the limiting block 9 is slidably connected to the limiting groove 8 .

[0023] The limiting groove 8 and the limiting block 9 limit the first shielding cover 5 and the second shielding cover 6 to facilitate the installation of the first shielding cover 5 and the second shielding cover 6.

[0024] Furthermore, rectangular blocks 10 are fixedly connected to both sides of the first shielding cover 5 , and rectangular grooves 11 are formed on the rectangular blocks 10 .

[0025] The rectangular block 10 and the rectangular groove 11 clamp one end of the pressing plate 14 to fix the first shielding cover 5 and the second shielding cover 6 .

[0026] Furthermore, rectangular plates 12 are fixedly connected to both sides of the second shielding cover 6 , sliding rods 13 are fixedly connected to the rectangular plates 12 , and a pressing plate 14 is slidably connected to the surface of the sliding rod 13 , and one end of the pressing plate 14 is located in the rectangular groove 11 .

[0027] When one end of the pressing plate 14 is pressed, the pressing plate 14 slides along the surface of the sliding rod 13 , and the other end of the pressing plate 14 tilts up and leaves the rectangular groove 11 , thereby separating the first shielding cover 5 from the second shielding cover 6 .

[0028] Furthermore, a spring 15 is fixedly connected to one side of the pressure plate 14 , one end of the spring 15 is fixedly connected to the second shielding cover 6 , a fixing bolt is threadedly connected to the threaded hole 7 , and limiting plates 16 are fixedly connected to both sides of the bottom shell 1 .

[0029] Among them, when the pressure plate 14 is pressed, the spring 15 contracts, and when the pressure plate 14 is released, the spring 15 rebounds, so that one end of the pressure plate 14 is buckled in the rectangular groove 11, and the fixing bolts fix the first connecting plate 2 and the second connecting plate 3 and the third connecting plate 4. The limiting plate 16 limits the shielding cover to avoid collision caused by displacement, thereby extending the service life of the shielding cover.

[0030] The working principle of this utility model:

[0031] When the shielding cover needs to be replaced, the fixing bolts in the threaded holes 7 are removed to separate the first connecting plate 2 from the second connecting plate 3 and the third connecting plate 4. One end of the pressure plate 14 is pressed, and the spring 15 contracts. The pressure plate 14 slides along the surface of the sliding rod 13. The pressed end of the pressure plate 14 is close to the second shielding cover 6, and the other end of the pressure plate 14 is tilted and leaves the rectangular groove 11, away from the first shielding cover 5, so that the first shielding cover 5 and the second shielding cover 6 can be separated. The practical structure is simple, and when the shielding cover needs to be replaced, it takes less time and is more convenient.
