Fig. 1A is a side exploded view of a non-directional connector 100 according to an embodiment of the invention. Fig. 1B is a side view of the unidirectional connector 100 according to an embodiment of the invention. Fig. 2 is a front view illustrating a circular socket 110 according to an embodiment of the present invention. Fig. 3 is a front view showing a circular plug 130 according to an embodiment of the present invention.

Please refer to fig. 1A to fig. 3. As shown in fig. 1A, the unidirectional connector 100 includes a circular socket 110 and a circular plug 130. The circular socket 110 includes an insulating housing 112 and a first magnetic element 114. The insulation seat 112 of the circular socket 110 has an abutting surface 112 a. The first magnetic element 114 surrounds the periphery of the abutting surface 112a of the insulating base 112 (as shown by the dotted line on the circular socket 110). The circular plug 130 includes an insulating body 132, a second magnetic element 134 and a conductive terminal 136. The insulative body 132 of the circular plug 130 has an abutment surface 132 a. The second magnetic element 134 surrounds the outer periphery of the mating surface 132a of the insulating body 132 at a position corresponding to the first magnetic element 114 (shown by a dotted line on the circular plug 130). The conductive terminals 136 are perpendicular to the mating surface 132a and extend from the mating surface 132a away from the insulating body 132.

In some embodiments, the conductive terminals 136 can extend and contract relative to the insulating body 132, in other words, the conductive terminals 136 can extend and protrude from the abutting surface 132a away from the insulating body 132, but when the abutting surface 112a of the circular socket 110 abuts against the abutting surface 132a of the circular plug 130 (as shown in fig. 1B), the conductive terminals 136 can be retracted and sunk into the insulating body 132, so that the abutting surface 112a of the circular socket 110 abuts against and contacts the abutting surface 132a of the circular plug 130.

In another embodiment, the conductive terminals 136 do not extend or contract relative to the insulative housing 132. In this embodiment, the conductive terminals 136 extend and protrude from the mating surface 132a away from the insulating body 132, so when the circular socket 110 is mated with the circular plug 130, the conductive terminals 136 will be abutted with the

conductive pads

116a and 116b (as shown in fig. 2) of the circular socket 110, and since the conductive terminals 136 will not extend and contract relative to the insulating body 132, a distance is formed between the mating surface 112a of the circular socket 110 and the mating surface 132a of the circular plug 130.

Please continue to refer to fig. 1A. The omnidirectional connector 100 further includes a mating auxiliary member 120, wherein the mating auxiliary member 120 has a first receiving groove 122 and a second receiving groove 124. The first receiving groove 122 is configured to receive the insulating base 112 of the circular socket 110. The second receiving groove 124 is configured to receive the insulating body 132 of the circular plug 130. The first receiving groove 122 and the second receiving groove 124 are communicated with each other and penetrate through the docking assistant member 120. A stopping surface a is disposed at a junction where the first receiving groove 122 and the second receiving groove 124 are communicated. Specifically, the second receiving groove 124 has a radius R larger than the radius R of the first receiving groove 122, such that the stopping surface a faces the direction of the second receiving groove 124. The inner wall of the first receiving groove 122 is connected to the inner wall of the second receiving groove 124 to form a step shape. The stopping surface a is used to control the insulating base 112 to be combined with the first receiving slot 122, or to control the insulating body 132 to be combined with the second receiving slot 124.

Please refer to fig. 2 and fig. 3. As shown in fig. 2 and 3, the first magnetic element 114 and the second magnetic element 134 have circular outer edges. Please refer back to fig. 1B. As shown in fig. 1B, the inner wall of the first receiving groove 122 slidably abuts against the circular outer edge of the first magnetic element 114, and the inner wall of the second receiving groove 124 slidably abuts against the circular outer edge of the second magnetic element 134, so that the docking assistant member 120 can rotate relative to the insulating base 112 and the insulating body 132 around an axis C perpendicular to the abutting surface 112a of the insulating base 112 and the abutting surface 132a of the insulating body 132. In other words, the insulation seat 112 or the insulation body 132 can also rotate unidirectionally 360 ° around the axis C perpendicular to the abutting surface 112a or the abutting surface 132a relative to the auxiliary docking element 120.

In some embodiments, the outer edges of the first magnetic element 114 and the second magnetic element 134 are not limited to continuous circular outer edges, and any shape that can achieve the same purpose as the present invention is suitable for this purpose, and the present invention is not limited thereto.

Please continue to refer to fig. 1B. The docking assistant member 120 can assist the circular socket 110 and the circular plug 130 to align themselves when the circular socket 110 and the circular plug 130 are docked. Specifically, the second magnetic element 134 also has a radius equal to the radius R of the second receiving groove 124, so when the circular plug 130 is disposed in the second receiving groove 124 and approaches the first receiving groove 122, since the radius of the second magnetic element 134 is greater than the radius R of the first receiving groove 122, the second magnetic element 134 is blocked by the blocking surface a, so that the circular plug 130 cannot approach the first receiving groove 122 any more, and the insulating body 132 is combined with the second receiving groove 124. At this time, when the circular socket 110 is placed in the first receiving groove 122, the first magnetic element 114 and the second magnetic element 134, which are respectively located outside the insulating base 112 and at opposite positions outside the insulating body 132, attract each other due to the magnetic force, so as to achieve the self-alignment function of the circular plug 130 and the circular socket 110.

In other embodiments, the stopping surface a faces the first receiving groove 122. That is, the radius R of the first receiving groove 122 is greater than the radius R of the second receiving groove 124, so that the stopping surface a faces the direction of the first receiving groove 122. In this embodiment, the first magnetic element 114 also has a radius equal to the radius R of the first receiving groove 122, so when the circular socket 110 is disposed in the first receiving groove 122 and approaches the second receiving groove 124, since the radius of the first magnetic element 114 is greater than the radius R of the second receiving groove 124, the first magnetic element 114 is blocked by the blocking surface a, so that the circular socket 110 cannot approach the second receiving groove 124 any more, and the insulating base 112 is combined with the first receiving groove 122.

Please refer to fig. 2. As shown in fig. 2, the conductive pad 116a is designed as a circular pad located at the center of the abutting surface 112a, and the two annular conductive pads 116b with different radii are concentrically arranged on the abutting surface 112a around the center of the conductive pad 116 a. The first magnetic element 114 of the circular socket 110 surrounds the peripheral periphery of the abutting surface 112 a. The

different pads

116a, 116b have different potentials, and each

pad

116a, 116b has an insulation distance L (only one is exemplarily indicated in the figure) therebetween, so as to ensure stable and safe electrical performance between the

pads

116a, 116 b. The size of the insulation distance L can be flexibly adjusted according to actual requirements, and the invention is not limited thereto.

In some embodiments, the number of the

conductive pads

116a, 116b is not limited to the embodiment shown in fig. 2, and the number of the

conductive pads

116a, 116b may be one or more than two, which can be flexibly adjusted and changed according to the actual requirement, which is not limited by the invention.

Please refer to fig. 3. As shown in fig. 3, there are five conductive terminals 136 (only one is exemplarily shown), and the conductive terminals 136 are disposed at positions contacting the

conductive pads

116a and 116b when the circular plug 130 is mated with the circular socket 110, in this embodiment, the five conductive terminals 136 are arranged in a straight line, wherein one conductive terminal 136 is disposed at the center of the mating surface 132a, and the remaining four conductive terminals 136 are disposed two by two symmetrically on the left and right sides of the central conductive terminal 136 with the central conductive terminal 136 as an axis. The second magnetic element 134 of the circular plug 130 surrounds the peripheral periphery of the mating face 132 a.

Fig. 4 is a schematic diagram illustrating the circular socket 110 and the conductive terminals 136 when the circular socket 110 in fig. 2 is mated with the circular plug 130 in fig. 3.

Please refer to fig. 4. When the circular socket 110 shown in fig. 2 is mated with the circular plug 130 shown in fig. 3, the five conductive terminals 136 are respectively in contact with and electrically connected to the

conductive pads

116a, 116 b. In more detail, the conductive terminal 136 located at the center of the abutting surface 132a contacts the conductive pad 116a located at the center of the abutting surface 112 a. The two conducting terminals 136 near the center contact the conducting pads 116b with smaller radius located at the inner circle. The two conducting terminals 136 away from the center are contacted with the conducting pad 116b with a larger radius located at the outer circle. With this configuration, the conductive terminal 136 can rotate around the center of the contact surface 132a by 360 degrees along the

conductive pads

116a and 116 b. In other words, the user can interface the circular socket 110 with the circular plug 130 in any direction under any circumstances without any deliberate alignment, so as to achieve the blind-mate function. When the circular socket 110 and the circular plug 130 are close to each other, the first magnetic element 114 and the second magnetic element 134, which are respectively located at the opposite positions of the insulating base 112 and the insulating body 132, attract each other due to the magnetic force, so as to assist the circular socket 110 and the circular plug 130 to be in alignment contact.

In some embodiments, the first magnetic element 114 is a magnet, and the second magnetic element 134 is a magnetic material, such as iron, cobalt, nickel, etc., but the invention is not limited thereto. In another embodiment, the first magnetic element 114 is a magnetic material and the second magnetic element 134 is a magnet. In other embodiments, the first magnetic element 114 and the second magnetic element 134 are opposite magnets.

Please continue to refer to fig. 4. As shown in fig. 4, the same pad 116b is in contact engagement with two conductive terminals 136. Thus, the two conductive terminals 136 are beneficial for stabilizing the current to tolerate a larger current between the conductive pad 116b and the conductive terminal 136. In some embodiments, the same conductive pad 116b is not limited to be in contact with two conductive terminals 136, but may be in contact with one conductive terminal 136, or may be in contact with more than two conductive terminals 136, which is not limited to the invention.

Fig. 5 is a front view of a circular socket 210 according to another embodiment of the present invention, wherein the first magnetic element 214 is adjacent to the conductive pad 116 b.

Please refer to fig. 5. In this embodiment, the

conductive pads

116a and 116b are the same as those in the embodiment shown in fig. 2, so that reference can be made to the above description for brevity. It should be noted that the difference between this embodiment and the embodiment shown in fig. 2 lies in that the conductive pad 116b closest to the outer edge in fig. 2 has a distance from the first magnetic element 214, and in this embodiment, the first magnetic element 214 is adjacent to the conductive pad 116 b.

Fig. 6 is a front view of a circular plug 230 according to another embodiment of the present invention, in which the conductive terminals 236 are arranged differently from those shown in fig. 3. Fig. 7 is a schematic diagram illustrating the circular receptacle 110 and the conductive terminals 236 when the circular receptacle 110 in fig. 2 is mated with the circular plug 230 in fig. 6.

Please refer to fig. 6. In this embodiment, the second magnetic element 134 is the same as the embodiment shown in fig. 3, so that reference can be made to the related description, which is not repeated herein. It should be noted that the difference between the present embodiment and the embodiment shown in fig. 3 lies in that the arrangement of the three conductive terminals 236 (only one is exemplarily shown) in the present embodiment is not in a straight line and the arrangement of the three conductive terminals 236 is in an asymmetric design. Specifically, one conductive terminal 236 is disposed at the center of the abutting surface 232a, and the other two conductive terminals 236, one conductive terminal 236, are disposed along the direction D1 in fig. 6. The other conductive terminal is disposed along the direction D2 in fig. 6, and the conductive terminal 236 disposed along the direction D2 is farther from the center conductive terminal 236 than the conductive terminal 236 disposed along the direction D1.

Please refer to fig. 7. As shown in fig. 7, when the circular receptacle 110 of fig. 2 is mated with the circular plug 230 of fig. 6, the conductive terminal 236 at the center of the mating face 232a contacts the conductive pad 116a at the center of the mating face 112 a. The conductive terminal 236 aligned along the direction D1 contacts the conductive pad 116b with a smaller radius located at the inner circle. The conductive terminal 136 aligned along the direction D2 contacts the conductive pad 116b with a larger radius at the outer circumference. With this structure, even if the conductive terminals 236 are not in a straight line or are not in a symmetrical arrangement, the conductive terminals 236 can rotate around the center of the contact surface 232a by 360 degrees along the

conductive pads

116a and 116b in an omnidirectional manner, so as to achieve the function of blind insertion. In addition, the conductive terminals 236 are arranged in an asymmetrical design as shown in FIG. 6, which can avoid the interference between two different potentials.

In some embodiments, the conductive terminals 236 arranged along the direction D1 are further from the center conductive terminal 236 than the conductive terminals 236 arranged along the direction D2. In the embodiment shown in fig. 6, the direction D1 is perpendicular to the direction D2. In other embodiments, the direction D1 and the direction D2 form an angle, such as 0-180 degrees. In other words, two other conductive terminals 236 disposed outside the center can be disposed at any position on the mating surface 232a corresponding to the conductive pad 116 b.

In some embodiments, the number and arrangement of the

conductive terminals

136, 236 are not limited to the embodiments shown in fig. 3 and 6. The number of the

conductive terminals

136, 236 may be two or more, and the arrangement may be symmetrical or asymmetrical. It is within the scope of the present disclosure that the

136, 236 may contact the

conductive pads

116a, 116b when the circular socket 110 is mated with the circular plug 130, and the present disclosure is not limited thereto.

Specifically, one of the two conductive terminals 336 is closer to the center of the mating surface 332a, and the other conductive terminal 336 is farther from the center of the mating surface 332 a.

Please refer to fig. 10. In this embodiment, the first magnetic element 114 and the conductive pad 116b are the same as those in the embodiment shown in fig. 4, so that reference can be made to the related description, and further description thereof is omitted.

magnetic elements

434a, 434b, and the two second

magnetic elements

434a, 434b are disposed in the outer edge of the insulating body 432 at the positions corresponding to the first

magnetic elements

414a, 414b in fig. 11. Specifically, the second magnetic element 434a is an annular magnetic element surrounding the conductive terminal 336, and the other second magnetic element 434b is disposed at the center of the abutting surface 432 a.

In some embodiments, the number and the positions of the second

magnetic elements

434a and 434b are not limited to those shown in fig. 12, and can be flexibly adjusted according to actual requirements. For example, the second

magnetic elements

434a, 434b can be disposed at any position on the mating surface 432a not occupied by the conductive terminal 336. The second

magnetic elements

434a and 434b may be embedded in the abutting surface 432a, or may be exposed through the abutting surface 432 a. The number of the second

magnetic elements

434a, 434b can be one or more, but the invention is not limited thereto.

In the embodiment shown in fig. 12, the insulating body 432 has a circular periphery, which is slidably abutted against the inner wall of the second receiving groove 124 of the docking assistant member 120 in fig. 1B, so that the docking assistant member 120 can rotate relative to the insulating body 432 around an axis C perpendicular to the docking surface 432a of the insulating body 432. In some embodiments, the periphery of the insulating body 432 is not limited to a continuous circular periphery, and any shape that can achieve the same purpose as the present invention is suitable for this purpose, and the present invention is not limited thereto.

Fig. 13 is a front view showing a circular socket 110 according to an embodiment of the present invention. Fig. 14 is a side view of the conductive pad 116a according to one embodiment of the invention. Fig. 15 is a side view of a conducting pad 116b according to another embodiment of the invention.

Please refer to fig. 13 to 15. As shown in fig. 13, a hole H is formed in the center of the contact surface 112a of the circular socket 110. Fig. 14 is a conductive pad 116a inserted into the hole H, that is, the conductive pad 116a shown in fig. 2, 4, 5, and 7. As shown in fig. 14, the conductive pad 116a is shaped like a nail when viewed from the side, and the hole H is configured to receive the conductive pad 116 a. Specifically, the conductive pad 116a has a lead 116a1 and a conductive pad surface 116a2, and the lead 116a1 is perpendicularly connected to the conductive pad surface 116a2 and extends away from the conductive pad surface 116a 2. When the conductive pad 116a is mounted in the hole H, the pin 116a1 is received in the hole H, so that, when the contact surface 112a of the circular socket 110 is viewed from the front, only the conductive pad surface 116a2 is exposed and forms a common plane with the contact surface 112 a. The pin 116a1 is received in the slot H and electrically connected to an external cable.

Please refer to fig. 13. The abutting surface 112a of the circular socket 110 is further formed with two grooves S, and the grooves S extend around the center (e.g., the position of the hole H) of the abutting surface 112a to form a circular annular groove S. The two circular annular grooves S have different radii, but the two grooves S are concentrically arranged in the abutting surface 112a around the center of the abutting surface 112 a. The recess S is configured to receive the conductive pad 116 b. There are two notches S1 at the bottom of each groove S. Fig. 15 shows the conductive pad 116b inserted into the recess S, i.e., the conductive pad 116b shown in fig. 2, 4, 5, 7, 8, 10 and 11. As shown in fig. 15, the conductive pad 116b has two leads 116b1, and two leads 116b1 are perpendicularly connected to a surface 116b3 opposite the conductive pad surface 116b2 and extend away from the conductive pad surface 116b 2. Specifically, the two leads 116b1 are hidden by the conductive pad face 116b2 when viewed from the front of the conductive pad face 116b 2. Therefore, when the conductive pad 116b is received in the groove S, the pin 116b1 is received in the notch S1 and electrically connected to an external cable.

In other embodiments, the conductive pad surfaces 116a2, 116b2 do not form a coplanar surface with the abutment surface 112 a. In other words, the conductive pad surfaces 116a2, 116b2 are relatively lower than the contact surface 112a and are received in the hole H or the recess S. In this embodiment, the conductive terminal 136 of the circular plug 130 can be inserted into the hole H or the recess S to contact the

conductive pads

116a and 116 b. Thus, even though the conductive terminal 136 is not able to extend or contract relative to the insulating body 132, the contact surface 112a and the contact surface 132a can still be in contact with each other.

In some embodiments, the positions and the number of the grooves S and the notches S1 are not limited to the embodiment shown in fig. 13, and can be adjusted and changed according to actual requirements.

Fig. 16 is a front view of a circular socket 110 'according to another embodiment of the present invention, wherein a plurality of notches S1' are formed on the outer edge of the recess S. Fig. 17 is a side view of a conductive pad 116 b' according to another embodiment of the invention.

Please refer to fig. 16. In this embodiment, the recess S and the hole H are the same as those in the embodiment shown in fig. 13, so that the related descriptions can be referred to and are not repeated herein. Note that the difference between this embodiment and the embodiment shown in fig. 13 is that the notch S1' in this embodiment is located at the bottom of the groove S. Please refer to fig. 17. As shown in fig. 17, the two leads 116b1 'of the conductive pad 116 b' are connected to the outer edge of the conductive pad face 116b2, and extend perpendicular to the conductive pad face 116b2 away from the conductive pad face 116b 2. Therefore, the connection between the two pins 116b 1' and the outer edge of the conductive pad 116b2 is protruded relative to the remaining outer edge of the conductive pad 116b 2. When the conductive pad 116b ' is mounted in the recess S, the notches S1 ' can receive the connection points between the leads 116b1 ' and the outer edges of the conductive pad faces 116b2 ', so that the conductive pad 116b ' can be compatibly matched with the recess S. The two pins 116b 1' are accommodated in the recess S and electrically connected to an external cable.

In some embodiments, the positions and the number of the grooves S and the notches S1' are not limited to the embodiment shown in fig. 16, and can be adjusted and varied according to actual requirements.

In some embodiments, the abutment surface 112a does not have a groove S or a hole H. In this embodiment, the

conductive pads

116a and 116b are disposed on the contact surface 112a and protrude from the contact surface 112a, but the invention is not limited thereto.

As is apparent from the above detailed description of the embodiments of the present invention, the anisotropic connector of the present invention is configured such that the circular ring-shaped conductive pads are concentrically arranged in the insulating base of the circular socket, so that the conductive terminals on the circular plug can contact the conductive pads no matter what angle the circular plug is mated with the circular socket. Further, with the aid of the docking aid, the circular plug and the circular socket can be self-aligned and matched, so that a user can dock the circular plug and the circular socket without any trouble under the invisible condition, and the blind-mate function is completely realized.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
