Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a multi-core connector with high shielding efficiency. Background Technology

[0002] High-shielding multi-core connectors are connection devices that can effectively resist electromagnetic interference and realize the transmission of multiple signals. They are widely used in fields with high electromagnetic compatibility requirements, such as electronics, communications, and military industries.

[0003] Existing high-shielding multi-core connectors employ a 360-degree shielding design with a metal sleeve. Traditional single metal sleeves suffer from the drawback of being unable to simultaneously provide shielding for both high and low frequencies. Furthermore, the rigid structure of the metal sleeve cannot be bent or fitted to irregularly shaped connectors, making it prone to shielding leakage due to assembly gaps. Utility Model Content

[0004] The purpose of this invention is to provide a multi-core connector with high shielding efficiency to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-core connector with high shielding efficiency, comprising a cable, a support ring, a high shielding efficiency cover, a male connector terminal, a female connector terminal, a socket, a slot, a threaded hole A, and a bolt. The support ring is fixed to the middle of the side end of the cable. The high shielding efficiency cover is installed on the side end of the support ring. The male connector terminal is installed at the rear end of the cable. The female connector terminal is installed in the middle of the socket. The slot is circumferentially opened on the outside of the female connector terminal through the socket. The threaded hole A is opened at the upper and lower ends of the socket respectively. The bolt or the threaded hole A fixes the high shielding efficiency cover to the slot.

[0006] Based on the above technical solution, the high shielding efficiency cover includes a fixing plate, a threaded hole B, a channel, a carbon black capsule, a magnetic fluid, and a fixing interface. The fixing plate has threaded holes B at its upper and lower ends, and the threaded holes B correspond to the threaded holes A. The fixing plate is opened in the middle of the channel, and the cable passes through the channel and through the fixing plate. The carbon black capsule is circumferentially fixed to the channel. The magnetic fluid is filled inside the carbon black capsule. The fixing interface is fixed to the end of the carbon black capsule.

[0007] Based on the above technical solution, the fixing plate drags and stretches the carbon black capsule to wrap around the connector female end and fix it to the socket.

[0008] Compared with existing technologies, this invention has the following advantages: By installing a carbon black envelope, including a high-shielding cover with magnetic fluid, at the male end of the connector, the carbon black reflects and absorbs high-frequency electromagnetic waves, while the magnetic fluid specifically absorbs low-frequency magnetic fields, naturally covering a wide frequency band without the need for a complex multi-layer structure. The flexible envelope design allows for bending and conforming to irregularly shaped connectors. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 4 As shown, a multi-core connector with high shielding effectiveness includes a cable 1, a support ring 2, a high shielding effectiveness cover 3, a male connector terminal 4, a female connector terminal 5, a socket 6, a slot 7, a threaded hole A8, and a bolt 9. The support ring 2 is fixed to the middle of the side end of the cable 1. The high shielding effectiveness cover 3 is installed on the side end of the support ring 2. The male connector terminal 4 is installed at the rear end of the cable 1. The female connector terminal 5 is installed in the middle of the socket 6. The slot 7 is circumferentially opened outside the female connector terminal 5 through the socket 6. The threaded hole A8 is opened at the upper and lower ends of the socket 6 respectively. The bolt 9 or the threaded hole A8 fixes the high shielding effectiveness cover 3 to the slot 7.

[0016] The high-shielding-efficiency cover 3 includes a fixing plate 10, a threaded hole B11, a channel 12, a carbon black capsule 13, a magnetic fluid 14, and a fixing interface 15. The fixing plate 10 has threaded holes B11 at its upper and lower ends, and the threaded holes B11 correspond to threaded holes A8. The fixing plate 10 is opened through the middle of the channel 12, and the cable 1 passes through the fixing plate 10 through the channel 12. The carbon black capsule 13 is circumferentially fixed to the channel 12. The magnetic fluid 14 fills the interior of the carbon black capsule 13. The fixing interface 15 is fixed to the end of the carbon black capsule 13.

[0017] The fixing plate 10 pulls and stretches the carbon black capsule 13 to wrap around the connector female end 5 and fix it to the socket 6.

[0018] The working principle of this utility model is as follows: In use, the male connector end 4 is inserted into the female connector end 5. Then, the fixing plate 10 is dragged and stretched to extend the carbon black capsule 13, which moves along the cable 1 through the channel 12. After the carbon black capsule 13 wraps around the female connector end 5, the fixing plate 10 is connected to the socket 6 through the slot 7. The bolt 9 connects the fixing plate 10 and the socket 6 through the threaded holes A8 and B11. Utilizing the carbon black material's reflection and absorption of high-frequency electromagnetic waves, and the magnetohydrodynamic material's targeted absorption of low-frequency magnetic fields, a wide frequency band can be naturally covered without a complex multi-layer structure. The flexible capsule design allows for bending and conforming to irregularly shaped multi-core connectors.

[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
