Description

Technical Field

[0001] The utility model relates to the field of adapters, in particular to a magnetic adapter. Background Art

[0002] The interface models of the signal input and output ends of electronic products sometimes vary. Therefore, an adapter is required to connect two electronic products with different interfaces.

[0003] The magnetic adapter can enable the ports of two electronic products to achieve magnetic easy connection without changing the original functions. When the connecting wire is accidentally tripped by someone during use, the plug will easily separate to ensure that the device in use is not pulled and dropped by an external force, so as to stay firmly in place.

[0004] The magnetic adapter includes two separate connectors to achieve the adaptation. Generally, a circuit board is welded to the connecting end of one of the connectors. In the face of today's 40Gbps / 80Gpbs ultra-high speed rate and 240W high-power charging type-C to type-C applications, this traditional split magnetic connection will cause the impedance coefficients of its physical characteristics to be superimposed due to the connection between the PCB and each separate device. Under 240W high-power charging, due to the relatively high impedance, the temperature is relatively high and the charging efficiency becomes low. Summary of the Utility Model

[0005] In order to reduce the adverse impact of the magnetic structure on the connection effect of the adapter, the utility model provides a magnetic adapter.

[0006] The magnetic adapter provided by the utility model adopts the following technical scheme:

[0007] A magnetic adapter includes a first connector, a first magnetic part, a second magnetic part and a second connector. The first magnetic part is arranged on the first connector, and the second magnetic part is arranged on the second connector. The first magnetic part and the second magnetic part are used to assist in connecting the first connector and the second connector. A first terminal is arranged in the first connector, and a second terminal is arranged in the second connector. One end of the first terminal extends to the end of the first terminal, and one end of the second terminal extends to the end of the second terminal. When the first magnetic part and the second magnetic part are magnetically attracted to each other, the end of the first terminal abuts against the end of the second terminal.

[0008] The first terminal is connected to the second terminal, enabling the two connectors to conduct. The first magnetic attraction part and the second magnetic attraction part are attracted to each other, causing the first terminal and the second terminal to stably abut, so that the first connector and the second connector are stably signal-conducted, and the two connectors are firmly connected. The arrangement of the first terminal and the second terminal replaces the original circuit board, reducing the steps of circuit board production and assembly, making it easier to produce and assemble the first connector and the second connector. At the same time, the direct conduction between the first terminal and the second terminal avoids the situation where the arrangement of the circuit board and the magnetic field interfere with each other and increase the circuit impedance, making the transfer adapter have higher transfer efficiency and less heat generation during use.

[0009] Preferably, an insertion port is formed at the end of the first connector, a plug-in part is provided at the end of the second connector, a part of the second terminal extends and fits on the side wall of the plug-in part, and the first terminal is fitted on the inner side wall of the insertion port.

[0010] The setting of the plug-in part provides a rigid support for the abutting end of the second terminal and the first terminal, making the second terminal not easily deformed during the process of abutting against the first terminal, so that the second terminal can stably abut against the first terminal.

[0011] Preferably, the length of the plug-in part is much smaller than the total length of the second terminal.

[0012] When the electronic device connected to the second terminal is moved, due to the short length of the plug-in part, the plug-in part can be easily pulled out from the insertion port, separating the two connected electronic devices, thus avoiding the situation where the main connected device is torn off.

[0013] Preferably, there are multiple first terminals and multiple second terminals; when the plug-in part is inserted into the insertion port, the multiple first terminals are respectively inserted between multiple pairs of adjacent second terminals, and both sides of the first terminal abut against the side walls of two adjacent second terminals.

[0014] The side walls of the first terminal and the second terminal abut against each other to realize the conduction between the first terminal and the second terminal. The abutment of the side walls increases the abutting area between the first terminal and the second terminal, making the conduction between the first terminal and the second terminal more stable.

[0015] Preferably, the first magnetic attraction part is arranged outside the housing of the first connector, and the second magnetic attraction part is arranged outside the housing of the second connector.

[0016] Through the housings of the first connector and the second connector, the first magnetic attraction part is separated from the circuit in the first connector, and the second magnetic attraction part is separated from the circuit in the second connector, which is beneficial to further reducing the influence of the first magnetic attraction part and the second magnetic attraction part on the transfer adapter.

[0017] Preferably, both the first magnetic attraction portion and the second magnetic attraction portion are annular. The first magnetic attraction portion is fixedly surrounded on the outer periphery of the first connector, and the second magnetic attraction portion is fixedly surrounded on the outer periphery of the second connector.

[0018] The annular magnetic attraction portions can make the magnetic attraction connection between the two magnetic attraction portions more stable, making the connection between the two connectors less likely to be disconnected.

[0019] Preferably, both ends of the insertion portion along its length direction are inclined guiding surfaces, and the ends of the two guiding surfaces away from the second connector extend towards the direction of approaching each other.

[0020] The guiding surfaces can assist the insertion portion to be inserted into the insertion opening, making it easier for the first terminals to be inserted between the adjacent second terminals.

[0021] In summary, the utility model has the following beneficial technical effects:

[0022] The first terminals are connected to the second terminals, thereby making the two connectors conduct. The first magnetic attraction portion and the second magnetic attraction portion are attracted together, making the first terminals and the second terminals stably abut against each other, thereby making the first connector and the second connector conduct signals stably and making the two connectors firmly connected. By providing the first terminals and the second terminals to replace the original circuit board, the steps of circuit board production and assembly are reduced, making it easier to produce and assemble the first connector and the second connector. At the same time, the direct conduction between the first terminals and the second terminals avoids the situation where the arrangement of the circuit board interferes with the magnetic field and increases the circuit impedance, making the transfer adapter have higher transmission efficiency and less heat generation during use.

[0026] The following Figure 1-2 further describes the utility model in detail with reference to the

[0027] An embodiment of the utility model discloses a magnetic attraction transfer adapter.

[0028] Referring to Figure 1 and Figure 2, A magnetic suction adapter, comprising a first connector 1, a first magnetic suction part 2, a second magnetic suction part 3 and a second connector 4. The first magnetic suction part 2 is arranged on the first connector 1, and the second magnetic suction part 3 is arranged on the second connector 4. The first magnetic suction part 2 and the second magnetic suction part 3 are used to assist in connecting the first connector 1 and the second connector 4. A first terminal 11 is arranged in the first connector 1, and a second terminal 41 is arranged in the second connector 4. One end of the first terminal 11 extends to the end of the first terminal 11, and one end of the second terminal 41 extends to the end of the second terminal 41. When the first magnetic suction part 2 and the second magnetic suction part 3 are magnetically attracted to each other, the end of the first terminal 11 abuts against the end of the second terminal 41.

[0029] The first terminal 11 and the second terminal 41 are connected to conduct electricity, so that the two connectors are conducted. The first magnetic suction part 2 and the second magnetic suction part 3 are attracted together, so that the first terminal 11 and the second terminal 41 are stably abutted, so that the first connector 1 and the second connector 4 are stably signal-conducted, and the two connectors are firmly connected. By setting the first terminal 11 and the second terminal 41 to replace the original circuit board, the steps of circuit board production and assembly are reduced, making it easier to produce and assemble the first connector 1 and the second connector 4. At the same time, the direct conduction of the first terminal 11 and the second terminal 41 avoids the situation that the setting of the circuit board interferes with the magnetic field and increases the circuit impedance, making the transfer efficiency of the adapter higher and the heat generation less during use.

[0030] Refer to Figure 1 And Figure 2 , In this embodiment, an insertion interface 12 is opened at the end of the first connector 1, and an insertion part 42 is arranged at the end of the second connector 4. A part of the second terminal 41 extends and fits on the side wall of the insertion part 42, and the first terminal 11 is fitted and arranged on the inner side wall of the insertion interface 12.

[0031] The setting of the insertion part 42 provides a rigid support for the abutting end of the second terminal 41 and the first terminal 11, so that the second terminal 41 is not easily deformed during the process of abutting against the first terminal 11, and the second terminal 41 can stably abut against the first terminal 11.

[0032] Refer to Figure 1 And Figure 2 , In this embodiment, the length of the insertion part 42 is much smaller than the total length of the second terminal 41.

[0033] When the electronic device connected to the second terminal 41 is moved, due to the short length of the insertion part 42, the insertion part 42 can be easily pulled out from the insertion interface 12, separating the two connected electronic devices, thus avoiding the situation that the main connected device is torn off.

[0034] Refer to Figure 1 And Figure 2, in this embodiment, there are multiple first terminals 11 and multiple second terminals 41. When the plugging portion 42 is plugged into the plugging opening 12, the multiple first terminals 11 are respectively plugged between multiple pairs of adjacent second terminals 41, and both sides of the first terminal 11 are in contact with the side walls of two adjacent second terminals 41.

[0035] The first terminal 11 is in contact with the side wall of the second terminal 41 to achieve conduction between the first terminal 11 and the second terminal 41. The contact of the side walls increases the contact area between the first terminal 11 and the second terminal 41, making the conduction between the first terminal 11 and the second terminal 41 more stable.

[0036] Refer to Figure 1 and Figure 2 , in this embodiment, the first magnetic attraction portion 2 is provided outside the housing of the first connector 1, and the second magnetic attraction portion 3 is provided outside the housing of the second connector 4.

[0037] Through the housings of the first connector 1 and the second connector 4, the first magnetic attraction portion 2 is separated from the circuit in the first connector 1, and the second magnetic attraction portion 3 is separated from the circuit in the second connector 4, which is beneficial to further reduce the influence of the first magnetic attraction portion 2 and the second magnetic attraction portion 3 on the adapter.

[0038] Refer to Figure 1 and Figure 2 , in this embodiment, both the first magnetic attraction portion 2 and the second magnetic attraction portion 3 are annular. The first magnetic attraction portion 2 is fixedly surrounded on the outer periphery of the first connector 1, and the second magnetic attraction portion 3 is fixedly surrounded on the outer periphery of the second connector 4.

[0039] The annular magnetic attraction portions can make the magnetic attraction connection between the two magnetic attraction portions more stable, making the connection between the two connectors less likely to be disconnected.

[0040] Refer to Figure 1 and Figure 2 , in this embodiment, both ends of the plugging portion 42 along its own length direction are inclined guide surfaces 43, and the ends of the two guide surfaces 43 away from the second connector 4 extend towards the direction of approaching each other.

[0041] The guide surfaces 43 can assist the plugging portion 42 to be plugged into the plugging opening 12, making it easier for the first terminal 11 to be plugged between adjacent second terminals 41.

[0042] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
