[0036] In this embodiment, a limit strip 4 and a limit groove 34 are provided to guide, limit and prevent the first shell 1 and the second shell 3 from being plugged in. In addition, a first elastic deformation member is provided on the limit strip 4, so that after the first shell 1 and the second shell 3 are plugged in, the limit strip 4 and the limit groove 34 are interference fit under the action of the first elastic deformation member, thereby effectively preventing loosening in the vertical direction and shaking in the horizontal direction.

[0037] In the embodiment of the present invention, the first elastic deformable member comprises a front elastic deformable member 41 disposed on the front wall of the limiting strip 4 and a side elastic deformable member 42 disposed on the side wall of the limiting strip 4;

[0038] The front elastic deformation member 41 and the side elastic deformation member 42 are both arranged along the height direction of the limiting strip 4 .

[0039] Specifically, through the above-mentioned arrangement, the front elastic deformation member 41 enables an interference fit between the front wall of the limit strip 4 and the bottom wall of the limit groove 34; the side elastic deformation member 42 enables an interference fit between the side wall of the limit strip 4 and the side wall of the limit groove 34; and the stability of the connector is further ensured.

[0040] In the embodiment of the power connector with stable connection, the thickness of the first elastic deformable member gradually increases from the end close to the second housing 3 to the end far from the second housing 3. The above arrangement facilitates the insertion of the first housing 1 and the second housing 3.

[0041] In the power connector with stable connection described in this embodiment, the first elastic deformable member is elastic silicone.

[0042] In the embodiment of the present invention, a power connector with a stable connection is provided with a plurality of second elastic deformable members 43 along the circumferential direction on the inner wall of the plug slot 12; the second elastic deformable members 43 are used to abut against the outer wall of the second boss 31. Specifically, through the above arrangement, after the first housing 1 and the second housing 3 are plugged in, the inner wall of the plug slot 12 and the outer wall of the second boss 31 are interference-fitted under the action of the second elastic deformable members 43.

[0043] In the embodiment of the present invention, the power connector with stable connection is characterized in that the thickness of the second elastic deformable member 43 gradually increases from the end close to the second housing 3 to the end far from the second housing 3; the second elastic deformable member 43 is elastic silicone. The above arrangement facilitates the insertion of the first housing 1 and the second housing 3.

[0044] The present embodiment describes a power connector with a stable connection, wherein a locking cap 5 is rotatably provided on the outer wall of the second shell 3; a locking groove 54 is provided in the locking cap 5; the first boss 11 is provided in the locking groove 54; a clamping block 51 is provided on the inner wall of the locking groove 54; and a clamping groove 81 cooperating with the clamping block 51 is provided on the outer wall of the first boss 11.

[0045] Specifically, the stability of the connector can be further ensured through the above configuration.

[0046] In the embodiment of the present invention, a power connector with a stable connection is provided at the top of the outer wall of the first boss 11 with an open groove 82 connected to the card slot 81; the width of the open groove 82 is smaller than the width of the card slot 81; the card block 51 enters the card slot 81 from the open groove 82. In the embodiment of the present invention, a power connector with a stable connection is provided at the inner wall of the open groove 82 with a first inclined surface 83; the bottom of the card block 51 is provided with a second inclined surface 52 that matches the first inclined surface 83. The above arrangement facilitates the card block 51 to enter the card slot 81 from the open groove 82.

[0047] The present embodiment describes a power connector with a stable connection, wherein the outer wall of the second shell 3 is provided with an arc groove 6 along the circumferential direction; an arc spring 61 is provided in the arc groove 6; the second shell 3 is provided with a connecting block 62 at one end of the arc groove 6; the second shell 3 is provided with a first stop block 63 at the other end of the arc groove 6; the inner wall of the locking groove 54 is provided with a second stop block 53 abutting against the first stop block 63; one end of the arc spring 61 is connected to the connecting block 62; the other end of the arc spring 61 is connected to the second stop block 53; the outer wall of the second shell 3 is provided with a rotating groove 71 along the circumferential direction; the inner wall of the locking groove 54 is provided with a rotating block 72 cooperating with the rotating groove 71.

[0048] Specifically, when the first housing 1 and the second housing 3 need to be installed, the limiting groove 34 of the second boss 31 is first aligned with the limiting strip 4 of the plug-in slot 12. At this time, the block 51 and the opening slot 82 are misaligned, and the block 51 cannot enter the opening slot 82. Therefore, the second housing 3 cannot be inserted into the first housing 1 at this time;

[0049] Then, the locking cap 5 is rotated so that the rotating block 72 rotates in the rotating groove 71 while the second resisting block 53 compresses the arc spring 61 until the block 51 is aligned with the top of the opening groove 82. At this time, the second shell 3 can be inserted into the first shell 1. After the insertion is completed, the block 51 is located at the connection between the groove 81 and the opening groove 82; then, the locking cap 5 is released, and under the action of the arc spring 61, the locking cap 5 is rotated and reset, thereby moving the block 51 to the depth of the groove 81. Under the action of the arc spring 61, the block 51 is firmly connected to the groove 81, thereby further ensuring the stability of the connector.

[0050] In the embodiment of the present invention, a power connector with a stable connection is provided with a third stopper 73 abutting against the rotating block 72 at one end of the rotating groove 71 of the second housing 3. Specifically, in the embodiment, by providing the third stopper 73, after the first housing 1 and the second housing 3 are plugged together, without rotating the locking cap 5, under the action of the circular arc spring 61, the rotating block 72 abuts against the third stopper 73, and at the same time, the first stopper 63 abuts against the second stopper 53, so that the locking cap 5 cannot be twisted in the reverse direction and can only be rotated along the compression direction of the circular arc spring 61, thereby enhancing the stability of the overall structure.

[0051] In this embodiment, under the action of the locking cap 5 , the first elastic deformable member and the first elastic deformable member 43 , after the first shell 1 and the second shell 3 are plugged together, the matching plugging and unplugging force is above 20 kg.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
