The magnetic needle tube 10 is provided with a movable cavity 11 for the needle shaft 20 to perform a telescopic motion, the movable cavity 11 penetrates the first end of the magnetic needle tube 10 along the axial direction (i.e. the direction indicated by the arrow a and the opposite direction) of the magnetic needle tube 10 to form a cavity opening 111, preferably, the cavity opening 111 is located at the end surface of the first end of the magnetic needle tube 10, but not limited thereto. The needle shaft 20 is slidably and telescopically sleeved in the movable cavity 11, so that the needle shaft 20 can be slidably and telescopically arranged in the movable cavity 11. The reset piece 30 is disposed in the movable chamber 11, and the needle shaft 20 is extended from the chamber opening 111 and is used for abutting against the female end conductive magnet 100a under the action of the reset piece 30, as shown in fig. 4. Specifically, the reset element 30 is an elastic element having elasticity, the elastic element is disposed between the magnetic needle tube 10 and the needle shaft 20, and the needle shaft 20 extends out of the cavity opening 111 under the elastic action of the elastic element and is used for abutting against the female end conductive magnet 100a, so as to provide better buffering and vibration resistance effects; for example, the elastic member is a spring, such as a spring made of a non-magnetic stainless steel material, and of course, the elastic member may also be an elastic rubber or an elastic silicone rubber according to actual needs, so that the invention is not limited thereto. It should be noted that the second end of the magnetic needle tube 10 in the male terminal 100b is used for being magnetically connected to one active device in the electronic product, and the end of the female conductive magnet 100a far away from the magnetic needle tube 10 is used for being magnetically connected to another active device in the electronic product, so that the two active devices can realize the transmission of current and/or signal under the effect of the magnetic connector 100 of the present invention. More specifically, the following:

as shown in fig. 1 to fig. 3, the magnetic connector 100 of the present invention further includes a housing 50, the housing 50 includes a base 51 and an annular partition wall 52 extending outward from the base 51 along an axial direction of the magnetic needle tube 10, the magnetic needle tube 10 penetrates the base 51, so that the magnetic needle tube 10 is assembled on the base 51, and the base 51 fixes the magnetic needle tube 10; and the first end of the magnetic needle tube 10 is located in the space 53 surrounded by the annular partition wall 52, as shown in fig. 1 to 3; wherein, the housing 50 improves the reliability of the butt joint between the first end of the magnetic needle tube 10 and the female end conductive magnet 100 a. Specifically, in fig. 1 to 3, two magnetic needle tubes 10 are spaced apart from each other on the housing 50, each magnetic needle tube 10 corresponds to one needle shaft 20 and one restoring member 30, and one female end conductive magnet 100a is abutted to the first ends of the two magnetic needle tubes 10 by one female end conductive magnet 100a, so as to reduce the number of the female end conductive magnets 100 a; of course, according to actual requirements, the number of the female end conductive magnets 100a may be the same as the number of the magnetic needle tubes 10, and when the number of the female end conductive magnets 100a is the same as the number of the magnetic needle tubes 10, each female end conductive magnet 100a is abutted to the first end of a corresponding one of the magnetic needle tubes 10. It is understood that the number of the magnetic needle tubes 10 may be one, three or four, and is not limited to the above examples.

As shown in fig. 4, an anti-corrosion conductive layer 41 is disposed on the surface of the female-end conductive magnet 100a, and anti-corrosion conductive layers 12 are disposed on the surfaces of the magnetic needle tube 10 and the needle shaft 20, so as to improve the anti-corrosion conductive performance of the female-end conductive magnet 100a and the magnetic needle tube 10; for example, the anti-corrosion conductive layer 12(41) is a gold plating layer to obtain better anti-corrosion conductivity, but not limited thereto. It is understood that the needle shaft 20 or the magnetic needle tube 10 may be provided with the anti-corrosion conductive layer 12 on its surface according to actual requirements, and the present invention is not limited thereto.

As shown in fig. 1, 2, 4 and 5, the needle shaft 20 is a copper needle shaft, which not only makes the needle shaft 20 have good electrical conductivity, but also makes the needle shaft 20 non-magnetic, so that the needle shaft 20 will not be attracted by the female end conductive magnet 100a when the female end conductive magnet 100a is abutted with the first end of the magnetic needle tube 10, thereby ensuring the reliability of the abutment of the female end conductive magnet 100a with the first end of the magnetic needle tube 10. Of course, the needle shaft 20 may be made of other materials, such as stainless steel needle shaft, according to the actual requirement, as long as the needle shaft 20 is ensured to have no magnetism, and therefore, the above examples are not limited.

As shown in fig. 1 to 5, the magnetic needle tube 10 is a magnetic stainless needle tube, and the magnetic needle tube 10 can perform current and/or signal transmission with the female end conductive magnet 100a while ensuring that the first end of the magnetic needle tube 10 can be magnetically attracted by the female end conductive magnet 100 a. Of course, the magnetic needle tube 10 may be made of other magnetic materials according to actual needs, as long as the magnetic needle tube 10 can transmit current and/or signals to the female end conductive magnet 100a, and the above example is not limited thereto.

As shown in fig. 1 to 4, the female terminal conductive magnet 100a has an elliptical cylindrical shape to prevent the female terminal conductive magnet 100a from rotating, but the female terminal conductive magnet 100a may have a cylindrical shape as needed. Since the female terminal conductive magnet 100a itself generates magnetic force and is used for transmitting signals and/or current, the female terminal conductive magnet 100a is made of a permanent magnet material, such as neodymium iron boron (ndfeb) material, ferrite material or permanent magnet alloy, but they are well known in the art and thus will not be described herein.

With reference to fig. 1 to 4, the process of butting the female end conductive magnet 100a and the first end of the magnetic needle tube 10 is described: first, the female-end conductive magnet 100a is placed in the space 53 surrounded by the annular partition wall 52, and the female-end conductive magnet 100a is axially aligned with the magnetic needle tube 10; then, under the action of the magnetic force generated by the female end conductive magnet 100a itself, the female end conductive magnet 100a slides toward the first end of the magnetic needle tube 10 until the female end conductive magnet 100a abuts against the first end of the magnetic needle tube 10, as shown in fig. 3 and 4. During the process of abutting the female end conductive magnet 100a with the first end of the magnetic needle tube 10, the female end conductive magnet 100a pushes the needle shaft 20 to move against the reset force provided by the reset piece 30, so that the needle shaft 20 retracts into the magnetic needle tube 10 when the female end conductive magnet 100a abuts with the first end of the magnetic needle tube 10, and keeps abutting with the female end conductive magnet 100a under the action of the reset piece 30.

Compared with the prior art, the magnetic connector 100 of the present invention has the effect of communicating current and/or signal without welding because the female end conductive magnet 100a is butted with the first end of the magnetic needle tube 10 in a magnetic adsorption manner, so as to realize the transmission of current and/or signal between the magnetic needle tube 10 and the female end conductive magnet 100 a; the female terminal conductive magnet 100a and the magnetic needle tube 10 are magnetically attracted to each other so as to be separated from each other. Meanwhile, the cooperation between the reset element 30 and the needle shaft 20 plays both a role of conduction and a role of buffering, so as to prevent the female end conductive magnet 100a and the magnetic needle tube 10 from being damaged by an excessive attraction force when being butted. Furthermore, the magnetic needle tube 10 can be magnetically connected to the active device under the magnetization of the female conductive magnet 100a, so that no soldering is required.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be limited thereto, since the equivalent changes and modifications of the present invention are intended to fall within the scope of the present invention.
