The first rubber core 1 can have a body portion 11 and a sleeve portion 12. A plurality of first terminal holes 13 are provided in the body portion 11, and the plurality of first terminal holes 13 penetrate to both ends of the body portion 11. One end of the sleeve portion 12 is connected to one end of the body portion 11, and the sleeve portion 12 is a hollow cylinder.

[0029] The plurality of first terminals 2 are made of conductive metal materials such as copper. The plurality of first terminals 2 are arranged on the first rubber core 1. The plurality of first terminals 2 can be male terminals. Each of the plurality of first terminals 2 has a first contact end 21 and a first connection end 22. The plurality of first terminals 2 can be respectively installed in the plurality of first terminal holes 13, so that the plurality of first terminals 2 are arranged on the body portion 11, and the first contact ends 21 and the first connection ends 22 of the plurality of first terminals 2 can respectively extend out of both ends of the body portion 11. The first connection ends 22 of the plurality of first terminals 2 can be used for connecting devices such as wire harnesses, and the first contact ends 21 of the plurality of first terminals 2 can extend into the sleeve portion 12 of the first rubber core 1.

[0030] The inner housing member 3 is made of materials such as plastic. The inner housing member 3 can be in the shape of a hollow cylinder. The inner housing member 3 is arranged outside the body portion 11 of the first rubber core 1, and the first connection ends 22 of the plurality of first terminals 2 can extend into the inner housing member 3, so that the first connection ends 22 of the plurality of first terminals 2 are better protected. A receiving seat 31 is provided on the outer side of the inner housing member 3 (such as Figure 4As shown, the accommodation seat 31 can be in the form of an annular seat body. There is an accommodation groove 32 inside the accommodation seat 31. The accommodation groove 32 extends in an arc shape and extends a predetermined length along the circumferential direction of the inner housing member 3. One side of the accommodation seat 31 is provided with an opening 33. The opening 33 communicates with the accommodation groove 32. The opening 33 faces the front of the first connector 100, that is, faces the insertion direction of the first connector 100. A first sealing ring 34 can also be sleeved on the outer side of the inner housing member 3. The first sealing ring 34 is close to the sleeve portion 12 of the first rubber core 1, which can increase the sealing effect when the first connector 100 and the second connector 200 are inserted.

[0031] The elastic component 4 is a compression spring. The elastic component 4 can be placed in the accommodation groove 32 along the axial direction A of the inner housing member 3 (as Figure 4 shown) through the opening 33.

[0032] The outer housing member 5 is made of materials such as plastic. The outer housing member 5 is sleeved outside the inner housing member 3. The elastic component 4 is arranged between the inner housing member 3 and the outer housing member 5, that is, the two ends of the elastic component 4 respectively abut against the inner housing member 3 and the outer housing member 5, and can provide a rotational reset force. In this embodiment, the outer housing member 5 is provided with a stop block 51 (as Figure 6 and Figure 7 shown).

The arc groove 35 communicates with the accommodation groove 32. The stop block 51 can be arc-shaped. The stop block 51 is movably arranged in the arc groove 35. The stop block 51 can move in the arc groove 35 and the accommodation groove 32 to compress and relax the elastic component 4, so that the elastic component 4 stably exerts a rotational reset force on the outer housing member 5.

[0034] Please refer to Figure 5, the second connector 200 can be a socket connector, including a second rubber core 6, a plurality of second terminals 7, and a housing 8. The second rubber core 6 is made of materials such as plastic. A plurality of second terminal holes 61 can be provided in the second rubber core 6, and the plurality of second terminal holes 61 penetrate through both ends of the second rubber core 6. A second sealing ring 62 can also be sleeved outside the second rubber core 6. The second sealing ring 62 is located between the second rubber core 6 and the housing 8, which can enhance the sealing effect.

[0035] The plurality of second terminals 7 are made of electrically conductive metal materials such as copper. The plurality of second terminals 7 are arranged on the second rubber core 6. The plurality of second terminals 7 can be female terminals, and each of the plurality of second terminals 7 has a second contact end 71 and a second connection end 72. The plurality of second terminals 7 can be respectively installed in the plurality of second terminal holes 61, and the second connection ends 72 of the plurality of second terminals 7 extend out of the second rubber core 6. The second connection ends 72 of the plurality of second terminals 7 can be used to connect devices such as wire harnesses.

[0036] In this embodiment, the second terminals 7 are female terminals. The second contact ends 71 of the plurality of second terminals 7 are hollow (as Figure 9 shown). On one side of the second contact end 71 of each of the plurality of second terminals 7, an elastic arm 73 is provided. One end (the rear end) of the elastic arm 73 is fixed to the second contact end 71, and the other end (the front end) of the elastic arm 73 forms a movable end, enabling the elastic arm 73 to swing freely. The elastic arm 73 inclines towards the center of the second terminal 7 at a predetermined angle, which can be used for elastic contact with the first terminal 2. At one end (the front end) of the second contact end 71 of each of the plurality of second terminals 7, an arc-shaped guiding surface 74 is provided. The arc-shaped guiding surface 74 is annular, which can guide the first contact end 21 of the first terminal 2 to be inserted into the second contact end 71 of the second terminal 7, enabling the first terminal 2 and the second terminal 7 to be smoothly plugged in. Preferably, a protruding point 75 can be provided near the movable end on the inner side of the elastic arm 73, which can be used to enhance the contact conduction effect between the first terminal 2 and the second terminal 7.

[0037] The housing 8 is made of materials such as plastic. The housing 8 is arranged outside the second rubber core 6. At least one buckle groove 81 is provided on the outside of the housing 8. In this embodiment, two buckle grooves 81 are provided on the outside of the housing 8, which can be buckled with the two buckle bodies 52. An insertion groove 82 can also be formed between the housing 8 and the second rubber core 6. The insertion groove 82 can be used for the sleeve portion 12 of the first rubber core 1 to be inserted. Since the above-mentioned buckle structure is a known technology and the present invention does not limit the buckle structure, it will not be elaborated here.

[0038] When the first connector 100 and the second connector 200 are plugged into each other (as Figure 8As shown in the figure, the first contact ends 21 of the plurality of first terminals 2 are respectively in contact with the second contact ends 71 of the plurality of second terminals 7 to achieve electrical connection, and the buckle body 52 and the buckle groove 81 can be buckled with each other to achieve the locking function. When the first connector 100 and the second connector 200 are inserted into each other, the sleeve portion 12 of the first rubber core 1 can be inserted between the outer housing 8 and the second rubber core 6, so that the first connector 100 and the second connector 200 are firmly joined. The first contact ends 21 of the plurality of first terminals 2 can also be inserted into the second rubber core 6, so that the first connector 100 and the second connector 200 are more firmly joined, and the first contact ends 21 of the plurality of first terminals 2 and the second contact ends 71 of the plurality of second terminals 7 are in more stable contact.
