Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically a high-current connector with shielding function. Background Technology
[0002] With the continuous development of electronic devices, the requirements for signal transmission stability and anti-interference ability are becoming increasingly higher. As a commonly used connection component in electronic devices, the performance of high-current connectors directly affects the working effect of the entire system.
[0003] Among existing high-current connectors, some products have insufficient shielding performance, making them susceptible to external electromagnetic interference. This can lead to unstable signal transmission and affect the normal operation of equipment. For example, in some high-frequency signal transmission scenarios, existing high-current connectors cannot effectively shield against external electromagnetic interference, causing signal distortion and attenuation, which reduces the communication quality and data transmission efficiency of the equipment. At the same time, high-current connectors generally have slots for cable insertion, but since these slots are exposed, water or dust can enter the high-current connector through them, causing damage.
[0004] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content
[0005] This invention provides a high-current connector with shielding function, which has the beneficial effects of good shielding function and strong protection effect, and solves the problems mentioned in the background art.

[0007] As an optional solution of this utility model, the low-frequency magnetic field shielding component is a high-permeability metal layer, a nanocrystalline alloy layer, or a conductive shielding material combined with a magnetic shielding layer, and the high-frequency electric field shielding component is a high-conductivity metal layer, a conductive coating, or a conductive plating.
[0008] As an optional solution of this utility model, the inner wall of the housing is provided with an installation groove, and the sealing ring is embedded in the installation groove.
[0009] As an optional solution of this utility model, a guide slide rod is movably sleeved on the side of the protective plate, and both ends of the guide slide rod are fixedly connected to limit side plates, which are fixedly connected to the shielding shell.

[0012] As an optional solution of this utility model, a toggle block is fixedly connected to the surface of the protective plate, and there are two guide slide rods, which are equidistantly arranged on both sides of the cable insertion groove.
[0013] This utility model has the following beneficial effects: 1.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Please see Figure 1-4 A shielded high-current connector includes a housing 1, a terminal 2 on one side of the housing 1, a cable insertion groove 3 on the other side of the housing 1, a shielding shell 4 on the surface of the housing 1, an insulating support 5 between the housing 1 and the shielding shell 4, a sealing ring 6 on the inner side of the housing 1, and a protective plate 8 on the surface of the shielding shell 4 relative to the cable insertion groove 3. The shielding shell 4 is composed of an outer low-frequency magnetic field shielding component and an inner high-frequency electric field shielding component.
[0022] Among them, the low-frequency magnetic field shielding component is a high-permeability metal layer, a nanocrystalline alloy layer, or a conductive shielding material combined with a magnetic shielding layer, while the high-frequency electric field shielding component is a high-conductivity metal layer, a conductive coating, or a conductive plating. The low-frequency magnetic field shielding component can effectively shield low-frequency magnetic field interference, and the high-frequency electric field shielding component can shield high-frequency electric field interference. The combination of the two greatly improves the shielding capability of the high-current connector against electromagnetic interference of different frequencies.
[0023] It should also be noted that the inner wall of the housing 1 is provided with an installation groove 7, and the sealing ring 6 is embedded in the installation groove 7. By providing the installation groove 7, it is convenient to install and replace the sealing ring 6.
[0024] Preferably, a guide slide rod 9 is movably sleeved on the side of the protective plate 8, and both ends of the guide slide rod 9 are fixedly connected to a limiting side plate 10, which is fixedly connected to the shielding shell 4. By setting the guide slide rod 9, it is convenient to move and guide the protective plate 8. By setting the limiting side plate 10, it is possible to prevent the protective plate 8 from detaching from the guide slide rod 9.
[0025] It should also be noted that a spring 11 is fitted on the surface of the guide slide rod 9, and the two ends of the spring 11 are connected to the limiting side plate 10 and the protective plate 8 respectively. By setting the spring 11, when the cable is inserted into the cable insertion slot 3 while the spring 11 is extended, the cable compression causes the protective plate 8 to slide to one side along the guide slide rod 9 and compress the spring 11. After the cable is pulled out, the spring 11 rebounds, causing the protective plate 8 to slide along the other side of the guide slide rod 9, covering the cable insertion slot 3 and playing a role in waterproofing and dustproofing.
[0026] Among them, an arc-shaped slot 12 is provided on one side of the protective plate 8 relative to the cable insertion slot 3. Multiple arc-shaped limiting strips 13 are equidistantly arranged on the inner side of the arc-shaped slot 12. By setting the arc-shaped slot 12 and the arc-shaped limiting strips 13, when inserting the cable, the arc-shaped slot 12 can be engaged with the shielding layer on the cable, and the arc-shaped limiting strips 13 can be engaged with the gap on the shielding layer, thereby fixing the cable and increasing its stability after insertion.
[0027] Furthermore, a toggle block 14 is fixedly connected to the surface of the protective plate 8, and there are two guide slide rods 9. The two guide slide rods 9 are equidistantly arranged on both sides of the cable insertion groove 3. By setting the toggle block 14, it is easy to toggle the protective plate 8 to slide on the guide slide rod 9. By equidistantly arranging the two guide slide rods 9 on both sides of the cable insertion groove 3, the stability of the protective plate 8 when sliding on the guide slide rod 9 can be increased.
[0028] Working principle: By setting the shielding shell 4, magnetic and electric fields can be shielded, improving the communication quality and data transmission efficiency of the high-current connector. By setting the insulating support 5, the connection between the shell 1 and the shielding shell 4 can be realized, and it can also play a role in insulation and anti-electric shock, increasing the safety of the device. By setting the sealing ring 6, the sealing performance of the contact point can be improved, and it can play a role in waterproofing and dustproofing. By setting the protective plate 8, guide slide rod 9, limiting side plate 10 and spring 11, when not in use, the cable insertion slot 3 can be shielded by the elastic force of spring 11, thereby playing a role in waterproofing and dustproofing. By setting the arc-shaped slot 12 and arc-shaped limiting strip 13, when the cable is inserted, the arc-shaped slot 12 can be engaged with the shielding layer on the cable, and the arc-shaped limiting strip 13 can be engaged with the gap on the shielding layer, thereby fixing the cable and increasing its stability after insertion.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
