Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

As shown in fig. 1, in the prior art, an annular elastic interference member 120 is assembled in a connector male member or female member of a certain annular cylinder structure 110, the elastic interference member 120 is used for enhancing the connection stability of the connector male member and female member after the connector male member and female member are adapted to be connected, each elastic interference section 121 in the elastic interference member 120 is respectively protruded and arched towards the central axis of the annular cylinder structure 110, the central axes of the single elastic interference section 121 and the annular cylinder structure 110 are all located in a plane β (except for two elastic interference sections 121 corresponding to 180 °), any two other elastic interference sections 121 are not located in the same plane β, as shown in the structural schematic diagram of fig. 2), therefore, when the connector male member and female member are adapted to be connected or separated, each elastic interference section 121 is almost elastically deformed in the plane β where the connector male member or female member is located (as shown in the simple structural schematic diagram of fig. 2 and 3), and the elastic force applied by the elastic interference section 121 to the connector male member or female member is also perpendicular to the wall surface of the connector male member or the wall surface (as shown in fig. 2), so that the elastic interference section 121 is deformed in the form of the elastic cylinder structure in a vertical direction. If the bulge Cheng Duguo of the curved arch of the elastic abutting section 121 is small, the abutting elastic force generated by the elastic deformation is too small to play a role in reinforcing the connection between the male member and the female member of the connector, and even the elastic abutting member 120 cannot be stably assembled on the inner wall surface of the ring barrel structure 110; and the precision required by processing is high, and the production difficulty is high. Therefore, the elastic abutting section 121 in the prior art has overlarge bending degree, so that larger insertion and extraction force is required to be applied when the male connector and the female connector are connected and separated in an adapting way, and in the process of using a product with the male connector and the female connector, a user is hard to insert and extract, so that bad experience is brought to the user, the male connector and the female connector are easy to wear, and the installation connection structure between the male connector and the female connector and the product main body is easy to shake and loosen after a period of use; on the basis of the large plugging force, the contact area of the metal is small, so that the conductivity improving effect is not good.

In order to solve the problems of the prior art, the first aspect of the present utility model provides an electrical connector male member 100, which can be adapted to connect with an electrical connector female member 200, wherein the electrical connector male member 100 includes a positive electrode and a negative electrode, the positive electrode and/or the negative electrode adopts a ring-shaped cylinder structure 110, an inner wall surface of the ring-shaped cylinder structure 110 is provided with a ring-shaped elastic interference member 120 having conductivity, the elastic interference member 120 includes a plurality of elastic interference sections 121 arranged side by side in a circumferential direction, each of the elastic interference sections 121 is arranged obliquely next to the adjacent elastic interference sections 121 on the same side, so that when the electrical connector male member 100 is adapted to connect with the electrical connector female member 200, the elastic interference member 120 is pressed by the electrical connector male member 100 and the electrical connector female member 200, and the elastic interference sections 121 are elastically deformed towards the circumferential direction of the elastic interference member 120 due to the pressing force, i.e. when all the elastic interference sections 121 are pressed and stressed, the elastic interference sections are elastically deformed along the originally inclined side instead of the deformation direction of the elastic interference sections 121 in the prior art as described above.

Compared to the elastic abutting member 120 of the prior art, the elastic abutting sections 121 of the present utility model are inclined in the natural state, so that after the elastic deformation occurs, the elastic deformation and deformation recovery stroke of each elastic abutting section 121 is not perpendicular to the wall surface of the annular cylinder structure 110 as in the prior art. The two structures of the prior art and the present utility model can be understood from the stress analysis shown in fig. 4, if the elastic potential energy stored by the deformation is the same: the elastic force output by the elastic abutting section 121 is not totally vertical to the wall surface of the annular cylinder structure 110, and the generated total abutting elastic force is dispersed in the direction, so that the insertion and extraction force required to be applied when the male part 100 and the female part of the electric connector are connected or separated in an adapting way is weakened, the problem of strong insertion and extraction hand feeling is solved, and the use experience feeling of a user is improved; and the elastic force output by the elastic interference piece 120 is enough to enhance the stability of interference connection of the two ring barrel structures 110; the plugging force is reduced, and the abrasion and loosening phenomena are also slowed down in the long-time use process, so that the service life is prolonged; further, the mechanism for automatically connecting and disconnecting the belt and the functions thereof can be more easily developed on the basis of the electric connector male member 100 and the electric connector female member 200.

For example, in some embodiments, the male member 100 of the electrical connector has two ring structures 110 for both the positive and negative electrodes; further, as shown in the embodiment of fig. 7, the positive and negative electrodes of the male member 100 of the electrical connector employ two ring structures 110 arranged in concentric circles.
