The permanent magnet 206 may be a magnetic structural member in an existing material, such as a permanent magnet, and the permanent magnet 206 may be formed into a long strip structure with an N pole and an S pole. One side of the first connecting soft iron 204 and the second connecting soft iron 205 is formed by a semicircular recess, and the semicircular recesses of the two are docked to accommodate the sliding bearing 207. The center of the permanent magnet 206 is coaxial with the sliding bearing 207, so that the permanent magnet 206 can be rotatably arranged on the sliding bearing 207. Preferably, the inner ring of the sliding bearing 207 has claws extending inwardly, and the claws may be formed with right-angled portions, and the two sides of the right-angled portions may abut against the permanent magnets 206 located at different rotational positions (i.e., Figure 4 and Figure 5 As shown in FIG. 2 , the claws may be formed as a first claw 213 and a second claw 214 so that the permanent magnet 206 is accurately positioned when rotating.

[0044] like Figure 6 As shown, in the embodiment, the contacting parts of the first connection soft iron 204 and the second connection soft iron 205 are respectively provided with the first copper block 208 and the second copper block 209, which are non-magnetic and can block the magnetic connection between the first connection soft iron 204 and the second connection soft iron 205. In addition, the size of the first copper block 208 and the second copper block 209 is smaller than the permanent magnet 206, so that after rotating the permanent magnet 206, the N pole and the S pole of the permanent magnet 206 can be simultaneously contacted with the same piece of connection soft iron, so that the magnetic clamping part 202 has no magnetic attraction to the outside.

[0045] Preferably, if Figures 4 to 6 As shown, in the embodiment, the top of the fourth housing is further provided with a second cover plate 210 and a rotating handle 211, the center of the second cover plate 210 is provided with a through hole 108, the center of the permanent magnet 206 is provided with a threaded hole, the center of the rotating handle 211 extends downward to form a connecting portion with an external thread, the rotating handle 211 is threadedly connected to the permanent magnet 206 through the connecting portion and the second cover plate 210, and an additional sealing ring can be provided between the second cover plate 210 and the permanent magnet 206 to improve the stability of the assembly. The rotating handle 211 can drive the permanent magnet 206 to rotate in the sliding bearing 207.

[0047] The use process of the connector with magnetic locking function is as follows: first, the socket part 1 is installed to a suitable use position through the mounting plate 106, and then the connecting nut 203 on the outer peripheral side of the second shell 201 is pushed to the end away from the pin 216 through the connecting spring 215. At this time, the pin 216 is plugged into the socket 103. After the plugging is completed, the connecting nut 203 is reset. When correctly installed, the recessed part 105 should be connected to the docking part 212 (such as Figure 6 If it is not installed properly, pull the connecting nut 203 and adjust the pin part 2 until it is installed properly. Figure 4 and Figure 5 As shown, in the embodiment, since the sliding bearing 207 is formed with a first claw 213 and a second claw 214, the permanent magnet 206 has two fixed positions, which are respectively as follows: Figure 5 As shown, the N pole and S pole of the permanent magnet 206 are respectively close to the first copper block 208 and the second copper block 209 in a non-magnetic and separable state; Figure 4 As shown, the N pole and the S pole of the permanent magnet 206 are respectively away from the first copper block 208 and the second copper block 209 in a magnetically attractive connection state.

[0048] like Figure 4 As shown, the N pole and S pole of the permanent magnet 206 are connected to the first connection soft iron 204 and the second connection soft iron 205 respectively. After the connection soft iron is magnetized, the magnetic clamping member 202 forms a magnetic whole. When the locking soft iron 104 of the magnetic locking member 102 is magnetized, the socket part 1 can be attracted to the pin part 2.

[0049] like Figure 5 As shown, the permanent magnet 206 is rotated ninety degrees by rotating the handle 211, and the N pole and S pole of the permanent magnet 206 are respectively rotated to the first copper block 208 and the second copper block 209. At this time, the N pole and S pole of the permanent magnet 206 are respectively in contact with the first connection soft iron 204 and the second connection soft iron 205 at the same time, forming a closed magnetic circuit, which has no magnetic attraction to the outside world, and the socket part 1 and the pin part 2 can be separated.

[0050] The connector with magnetic locking function can quickly connect the socket part 1 and the pin part 2 by means of the snap-fitting cooperation of the magnetic locking member 102 and the magnetic snap-fit ​​member 202. The structure is simple and the operation is convenient. The locking and releasing can be achieved by rotating the rotating handle 211 ninety degrees, thus realizing the secondary locking function of the connector, making the connection of the connector more reliable and firm. The overall assembly is simple, the cost is low and the economy is good.
