Description

Technical Field

[0001] This utility model belongs to the technical field of cable protective shells, specifically relating to an anti-electromagnetic interference shell for cables. Background Technology

[0002] A cable is a conductor used to transmit electrical energy or signals. It typically consists of one or more insulated conductors encased in insulating material. Cables are widely used in power transmission, communications, industrial control, and building wiring. Electromagnetic interference (EMI) refers to any electromagnetic energy that can disrupt, hinder, or affect the normal operation of electronic equipment. It is usually caused by external electromagnetic fields or noise in internal circuits, leading to degraded equipment performance or malfunctions.

[0003] Existing cable sheaths are generally made of PVC and rubber. In specific areas such as substations, around large motor equipment, and near welders and induction heaters, cables are susceptible to electromagnetic interference. PVC and rubber sheaths have poor electromagnetic interference resistance, which affects cable use. At the same time, some existing cables also use metal sheaths. Metal sheaths have high mechanical strength and good electromagnetic shielding performance, but the specifications of metal sheaths are fixed, making them difficult to adapt to different cable specifications, resulting in poor applicability and affecting use. Utility Model Content

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, an electromagnetic interference resistant housing for a cable includes: a first housing 1 and a second housing 2. Mounting plates 3 are fixedly installed on the inner sidewalls of both the first housing 1 and the second housing 2. Mounting plates 3 are connected to a fixing frame 5 via an elastic component. A cable body 4 is installed inside the fixing frame 5. A protective mechanism is installed inside the fixing frame 5. A connecting component is provided between the first housing 1 and the second housing 2. A limiting component is provided between the first housing 1 and the second housing 2.

[0025] The protective mechanism includes a conductive shielding layer 6 fixedly installed on the inner wall of the fixed frame 5. The conductive shielding layer 6 is made of aluminum foil. An insulating layer 7 is fixedly installed on the inner wall of the conductive shielding layer 6. A filling layer 8 is fixedly installed on the inner wall of the insulating layer 7. The filling layer 8 and the cable body 4 are in tight contact.

[0026] As can be seen from the above, by setting the conductive shielding layer 6 to cover the cable body 4, the electromagnetic interference resistance of the cable body 4 is improved. The conductive shielding layer 6 is aluminum foil. As a lightweight conductive material, aluminum foil has good electromagnetic shielding performance and can effectively reflect and absorb electromagnetic waves, thereby reducing electromagnetic interference. By setting the insulation layer 7, which is made of polyethylene, short circuits between the cable body 4 and the conductive shielding layer 6 are prevented, ensuring electrical safety. The filling layer 8 is made of rubber. When the two fixing frames 5 are attached to each other, the cable body 4 is squeezed and deformed by the elastic component, so that the filling layer 8 and the cable body 4 are in close contact and tightly attached, which facilitates the clamping and fixing of the cable body 4. At the same time, it also makes the device easy to clamp and fix cables of different specifications, improving the applicability of the device.

[0027] The connection components facilitate relative movement between the first housing 1 and the second housing 2, allowing them to move closer and further apart, and facilitating the installation and removal of the cable body 4. The limiting components limit and fix the first housing 1 and the second housing 2 when their sides are in contact, thus completing the installation.

[0028] Specifically, regarding the aforementioned flexible components and connecting components, please refer to... Figure 2 and Figure 3 As shown, the elastic component includes a fixed plate 9 fixedly installed at the top and bottom of the fixed frame 5. Multiple connecting rods 10 are fixedly installed on the outer wall of the fixed plate 9. Each of the multiple connecting rods 10 passes through the corresponding mounting plate 3 and is fixedly installed with a limit block. A first spring 11 is sleeved on the outer wall of the connecting rod 10. The two ends of the first spring 11 are fixedly connected to the outer wall of the fixed plate 9 and the outer wall of the mounting plate 3, respectively.

[0029] The connecting assembly includes a mounting groove on the bottom outer wall of the first housing 1, a connecting plate 12 fixedly disposed on the inner wall of the mounting groove, a connecting cavity on the inner wall of the second housing 2, a movable block 13 slidably disposed on the inner wall of the connecting cavity, and the end of the connecting plate 12 away from the first housing 1 passing through the connecting cavity and fixedly connected to the outer wall of the movable block 13.

[0030] As can be seen from the above, when the first housing 1 and the second housing 2 are brought close to each other, the connecting plate 12 drives the movable block 13 to move away from the first housing 1, so that the sides of the first housing 1 and the second housing 2 are in contact. At this time, the two fixed frames 5 are pressed against each other, so that the first spring 11 is compressed, thereby applying a pushing force to the fixed frame 5 through the first spring 11, so that the fixed frame 5 clamps and fixes the cable body 4.

[0031] Specifically, regarding the aforementioned limit components, please refer to... Figure 1 , Figure 2 and Figure 4 As shown, the limiting component includes a rotating plate 14 rotatably disposed on the top of the second housing 2. The rotating plate 14 is L-shaped and a locking block 15 is fixedly disposed at the end of the rotating plate 14. A slot adapted to the locking block 15 is opened on the top of the first housing 1. The locking block 15 is inserted into the slot. A pushing component is provided on the top of the second housing 2.

[0032] A rubber sleeve 16 is fixedly fitted to the outer wall of the locking block 15, and the end of the locking block 15 away from the rotating plate 14 is set in an arc shape.

[0033] As can be seen from the above, by rotating the rotating plate 14, the locking block 15 is inserted into the slot, thereby limiting and fixing the first housing 1 and the second housing 2. Under the action of the pushing component, a thrust is applied to the rotating plate 14, making the rotating plate 14 stable and improving the fixing effect. The rubber sleeve 16 makes it easy for the locking block 15 to deform and squeeze into and out of the slot. When it is necessary to separate the first housing 1 and the second housing 2, pull the rotating plate 14 to make the locking block 15 disengage from the slot, thereby releasing the limitation and facilitating the separation of the first housing 1 and the second housing 2.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 and Figure 4 As shown, the pushing component includes a mounting block 17 fixedly mounted on the top of the second housing 2. The outer side wall of the mounting block 17 has a movable groove, and a push plate 18 is slidably mounted on the inner side wall of the movable groove. The outer side wall of the push plate 18 and the outer side wall of the rotating plate 14 are in close contact.

[0036] As can be seen from the above, by setting and using the push plate 18, the rotating plate 14 is limited, so that the connection between the card block 15 and the card slot remains stable and the fixing effect is improved.

[0037] Preferably, the push plate 18 is arc-shaped at one end near the rotating plate 14, and a second spring 19 is fixedly installed on the outer wall of the push plate 18. The end of the second spring 19 away from the push plate 18 is fixedly installed on the inner wall of the movable groove.

[0038] As can be seen from the above, by setting and using the second spring 19, the second spring 19 is in a compressed state, applying a pushing force to the push plate 18, so that the push plate 18 can tightly press against the rotating plate 14 and limit the rotation plate 14.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
