As shown in FIG. 1 to FIG. 4, the present invention provides a high current connector including a first connector 100, an elastic electrical conductor 150 and a second connector 200. As shown in the first embodiment, the first connector 100 and the second connector 200 are preferably cylindrical connectors electrically connected to each other (not labeled), and are connected to each other to transmit, for example. The current of 100 to 400 amps or more; however, the kind or appearance of the first connector 100 and the second connector 200 is not limited to the embodiment.

The first connector 100 is, for example, a female connector that includes a slot 110. The elastic electrical conductor 150 is received in the slot 110. The elastic electrical conductor 150 has an elastic body 160, a socket space 170 located in the elastic body 160, and a plurality of spaces 180 formed on the circumferential surface of the elastic body 160. The second connector 200 is, for example, a male connector that includes a guiding body 210 that is inserted into the docking space 170. The guiding body 210 is electrically connected to the first connector 100 by the elastic electric conductor 150, and is fixed to the slot 110 through the change of each interval 180.

As shown in FIG. 2, FIG. 3 and FIG. 10, the socket 110, the guiding body 210 and the elastic electric conductor 150 are all made of a conductive material such as copper, iron or an alloy thereof. The elastic body 160 further has an outer circumferential surface 152, an inner circumferential surface 154 opposite to the outer circumferential surface 152, and an axial line 156 coaxial with the outer circumferential surface 152 and the inner circumferential surface 154. In the present embodiment, the outer circumferential surface 152 is more inclined with the axial line 156, and the inner circumferential surface 154 is parallel to the axial line 156.

In other words, the shape of the slot 110 of the first connector 100 is preferably a conical groove, and the contour shape of the elastic electric conductor 150 is a cone with respect to the conical groove. The insertion space 170 of the elastic electric conductor 150 has a cylindrical groove shape, and the shape of the guiding body 210 is a cylinder with respect to the cylindrical groove.

However, in the embodiment shown in Figures 8 and 9, the inner circumferential surface 154 can also be inclined with the axial line 156, while the outer circumferential surface 152 is parallel to the axial line 156. In other words, the shape of the slot 110 of the first connector 100 is a cylindrical slot, and the contour shape of the elastic electrical conductor 150 is a cylinder with respect to the cylindrical slot. The shape of the insertion space 170 of the elastic electric conductor 150 is a conical groove, and the shape of the guiding body 210 is a cone with respect to the conical groove.

Each of the spacers 180 preferably extends through the outer circumferential surface 152 and the inner circumferential surface 154, and the spacers 180 are connected to each other to form a spiral S, so that the elastic electrical conductor 150 is formed into a cylindrical coil spring, a conical coil spring or other suitable coil spring. .

Referring to FIG. 5 and FIG. 6 together, when the elastic electrical conductor 150 is inserted into the slot 110 of the first connector 100, the length of the elastic electrical conductor 150 is smaller than the length of the slot 110. At this time, the outer circumferential surface 152 of the elastic electric conductor 150 contacts the wall surface of the socket 110, and the inner circumferential surface 154 contacts the annular surface of the guiding body 210. When the guiding body 210 of the second connector 200 is inserted into the slot 110 of the first connector 100 and further pushed against the bottom end of the elastic conductor 150, each interval 180 is caused by the spiral S of the elastic body 160. The spacing is pushed up to become larger.

That is, in the first preferred embodiment, the elastic conductor 150 having a conical shape and contoured is elastically elongated by the pushing of the guiding body 210, and the intervals 180 are also increased. Due to the elastic property of the elastic conductor 150 itself and the shape of the corresponding slot 110, the outer circumferential surface 152 is more closely contacted with the wall surface of the slot 110, and the inner circumferential surface 154 is also tightly coupled with the guiding body 210. The effect is that the first connector 100 and the second connector 200 are better in plugging quality, thereby achieving a safe, reliable and stable connection effect.

The elastic electrical conductor 150 of the present embodiment further includes a closed end 162 disposed at one end of the elastic body 160 and a locking portion 164 opposite the outer edge of the other end of the closed end 162. The first connector 100 is formed with a recess 112 relative to the fastening portion 164 to position the elastic electrical conductor 150 in the slot 110. A locking portion 164 such as a flange as shown in FIG. 7 enables one end of the elastic electric conductor 150 to be positioned at the leading edge of the slot 110 to prevent the end of the elastic body 160 from being pushed when the guiding body 210 is inserted into the elastic electric conductor 150. The ground moves toward the bottom end of the slot 110 to affect the effect of the elastic electrical conductor 150 tightening the guiding body 210 and the wall of the contact slot 110.

Please refer to FIG. 8 together for a partial cross-sectional view of the third embodiment of the present creation. The main difference between this embodiment and the foregoing embodiment is that the tightening effect is reversed, that is, the slot 110 of the first connector 100 is a cylindrical slot, and the elastic electrical conductor 150 is a cylinder. The guiding body 150 is a cone, and the insertion space 170 is a conical groove. When the guiding body 210 is inserted into the slot 110 provided with the elastic electric conductor 150, the elastic body 160 is elastically elongated by being pushed by the guiding body 210. Since the tapered body 210 is movably pushed against the corresponding insertion space 170, the inner circumferential surface 154 of the elastic electrical conductor 150 is tightly contacted with the guiding body 210, and the outer circumferential surface 152 is also It can be in contact with the wall surface of the slot 110.
