Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a magnetic attraction type radio frequency connector. Background Art

[0002] In the existing portable communication device communication network, the connection between communication devices relies on a combination of wired and wireless methods. Wireless connection is usually achieved by equipment such as base stations and repeaters, while wired connection widely uses radio frequency (RF) cables.

[0003] However, most existing RF connectors use a mechanical locking mechanism to ensure the stability of the connection. Although this mechanism can achieve a firm connection to a certain extent, it has the following shortcomings in practical applications:

[0004] (1) Complicated operation. When performing emergency maintenance or quickly replacing connectors on site, removing mechanically locked connectors requires external force or tools, which is complicated and time-consuming, and may delay the restoration of communications.

[0005] (ii) Reduced reliability: After multiple disassembly and assembly, the mechanical locking mechanism is prone to wear, which affects the reliability of the connection.

[0006] (3) Complex design and high manufacturing cost. The structural design of the mechanical locking mechanism is usually complex, which increases the difficulty and cost of manufacturing and maintenance.

[0007] Therefore, there is still much room for improvement in the existing RF connector locking mechanism in terms of convenience, reliability and economy. Summary of the invention

[0010] A further solution is that when the first magnetic pole is the N pole, the second magnetic pole is set to the S pole; when the second magnetic pole is the N pole, the first magnetic pole is set to the S pole.

[0011] A further solution is that at least four first magnet units are arranged at equal intervals along the circumference of the first connector, and the number of the first magnet units is an even number.

[0012] A further solution is that an inner conductor jack is provided in the first connector, and a conductor plug matched with the inner conductor jack is provided in the second connector.

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example 1.

[0027] like Figure 1As shown, the magnetic attraction type RF connector described in this embodiment includes a first connector 10 and a second connector 20, wherein the end of the first connector 10 is provided with a first magnetic attraction portion 30, and the end of the second connector 20 is provided with a second magnetic attraction portion 40 that is connected to the first magnetic attraction portion 30; the first magnetic attraction portion 30 includes a plurality of first magnetic units 31 arranged at equal intervals along the circumference of the first connector 10, and the second magnetic attraction portion 40 includes a plurality of second magnetic units 41 arranged at equal intervals along the circumference of the second connector 20, and the number of the second magnetic units 41 is equal to the number of the first magnetic units 31. The same amount; adjacent first magnet units 31 are spaced apart to form first slots 32, the depth and width of the first slots 32 are adapted to the length and width of the second magnet unit 41, and the side of the first magnet unit 31 facing the first connector 10 is the first magnetic pole, and the other side is the second magnetic pole; adjacent second magnet units 41 are spaced apart to form second slots 42, the depth and width of the second slots 42 are adapted to the length and width of the first magnet unit, and the side of the second magnet unit 41 facing the second connector 20 is the first magnetic pole, and the other side is the second magnetic pole.

[0028] In this embodiment, when the first magnetic pole is the N pole, the second magnetic pole is set to the S pole; when the second magnetic pole is the N pole, the first magnetic pole is set to the S pole. Figure 2 and Figure 3 As shown, the first magnetic pole is set to be an S pole, and the second magnetic pole is set to be an N pole.

[0029] When using, Figure 2 As shown, the end of the first connector 10 is aligned with the end of the second connector 20, so that the first magnetic attraction portion 30 faces the second magnetic attraction portion 40. Then, the first magnet unit 31 is aligned with the second slot 42, and the second magnet unit 41 is aligned with the first slot 32.

[0030] like Figure 6 As shown, as the second connector 20 is pushed axially, when the first magnet unit 31 and the second magnet unit 41 are close enough, since the magnetic poles of the adjacent magnet units are set as opposite magnetic poles, the force of attraction between the opposite poles will automatically guide and lock the first magnet unit 31 into the second slot 42 and the second magnet unit 41 into the first slot 32, thereby realizing fast and accurate docking of the first connector 10 and the second connector 20.

[0031] This design not only uses the principle of magnetic attraction to achieve automatic alignment and precise docking, but also the depth and width of the first slot 32 and the second slot 42 respectively match the length and width of the second magnet unit 41 and the first magnet unit 31, which can provide physical restraint and fixation for the first magnetic attraction part 30 and the second magnetic attraction part 40 after docking, ensuring the stability and reliability of the connection.

[0032] When the connection needs to be disassembled, the operation is very simple. It is only necessary to apply an appropriate separation force along the axial direction of the connector until the first magnetic unit 31 and the second magnetic unit 41 are in contact with one side of the same magnetic pole. A mutually repelling magnetic force will be generated between them. Therefore, by utilizing the effect of like poles repelling each other, the first connector 10 and the second connector 20 can be quickly separated under the guidance of external force. After disassembly, due to the use of the magnetic attraction principle, the entire connection structure has no moving and wearing parts, and can maintain the performance of the magnetic unit and the connection part for a long time, ensuring that after repeated connection and disassembly, it can still maintain excellent connection reliability and working stability.

[0033] In this embodiment, at least four of the first magnet units 31 are arranged at equal intervals along the circumference of the first connector, and the number of the first magnet units 31 is an even number. In this embodiment, the number of the first magnet units 31 and the second magnet units 41 are both set to four, and the even number of magnet units constitutes a symmetrical design, which not only avoids the unbalanced force that may be generated by an odd number of magnets, but also when connecting the end of the first connector 10 to align with the second connector 20, it is only necessary to align any second magnet unit 41 with any first slot 32 and insert it without special matching, which greatly improves the convenience of use.

[0034] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the first connector 10 is provided with an inner conductor jack 11, and the second connector 20 is provided with a conductor plug 21 adapted to the inner conductor jack 11. The design of the inner conductor jack 11 and the conductor plug 21 is to support the normal transmission function of the RF connector. In actual applications, the inner conductor jack 11 needs to be connected to an external communication cable, and the conductor plug 21 needs to be connected to a corresponding communication device to establish the entire RF communication link. Here, the method of connecting the inner conductor jack 11 / conductor plug 21 to an external communication cable / device can use known technology, so a detailed description will be omitted.

[0035] In this embodiment, if Figure 2 , Figure 3 and Figure 4As shown. The second connector 20 is also provided with a first shielding cover 22, which is arranged around the conductor plug 21 along the circumference of the conductor plug 21. The first connector 10 is also provided with a second shielding cover 12 adapted to the first shielding cover 22. When the conductor plug 21 is plugged into the inner conductor jack 11, the first shielding cover 22 and the second shielding cover 12 are mutually nested to cover the conductor plug 21 and the inner conductor jack 11. In this embodiment, the first shielding cover 22 and the second shielding cover 12 are made of insulating materials with magnetic shielding properties to effectively isolate the influence of the first magnetic attraction portion 30 on the transmission of the RF signal toward the second magnetic attraction portion 40, reduce signal attenuation and distortion, and ensure the integrity and quality of the signal.

[0036] In this embodiment, if Figure 2 and Figure 4 As shown, a shielding sleeve 50 is formed by extending the peripheral edge of the second connector 20. When the first connector 10 and the second connector 20 are fixed by magnetic attraction, the first magnetic attraction portion 30 and the second magnetic attraction portion 40 are both placed in the shielding sleeve 50. In this embodiment, the shielding sleeve 50 is also made of an insulating material with magnetic shielding properties to reduce the interference of the magnetic field generated by the first magnetic attraction portion 30 toward the second magnetic attraction portion 40 on surrounding electronic equipment and cables. At the same time, it can also block the entry of external impurities such as dust and moisture to a certain extent, thereby improving the dust and water resistance of the connector.

[0037] In this embodiment, if Figure 4 and Figure 5 As shown, a first silicone pad 51 is provided on the inner wall of the shielding sleeve 50 on the side away from the second connector 20, and a second silicone pad 52 matched with the first silicone pad 51 is provided on the circumferential surface of the first connector 10. With this structural design, on the one hand, a reliable sealing structure can be formed to effectively block the invasion of humid air and liquid, thereby significantly improving the waterproof and moisture-proof performance of the entire connector. On the other hand, the first silicone pad 51 and the second silicone pad 52 are in contact with each other during assembly and connection, and their soft silicone material can provide a damping and buffering effect for the docking process of the second connector 20 and the first connector 10, optimizing the assembly feel experience of the operator, that is, when the two connectors reach the precise docking position, the staff will be able to clearly feel the damping feedback changes generated by the silicone pad, thereby judging that the connection is in place, avoiding the situation where the connection is not in place and affecting the communication quality.

[0038] In this embodiment, anti-skid patterns (not shown) are provided on the outer surface of the shielding sleeve 50. The anti-skid patterns can improve the roughness and friction of the surface of the shielding sleeve 50, so that the operator can obtain a more secure grip when assembling or disassembling the connector, reducing the risk of operating errors caused by hand slippage and improving the reliability of operation.

[0039] The magnetic RF connector provided in this embodiment arranges multiple magnetic units in a specific arrangement at the end of the connector to form a slot, and utilizes the principle of attraction and repulsion between the magnetic poles of the magnetic units to enable the connector to be quickly docked and separated, and can be quickly disassembled without the aid of additional tools or the application of large force, which greatly simplifies the operation and improves work efficiency. Compared with complex mechanical locking mechanisms, its magnetic design can effectively prevent accidental disconnection caused by factors such as vibration, and there is no need to worry about wear and tear during repeated disassembly and assembly.
