Optionally, the second shell assembly 32 may include a second connection shell 324, and the second connection shell 324 is disposed on the second outer shell 322 and a side of the second limiting shell 323 facing the second conducting wire 31, and is used for transitioning a joint of the second shell assembly 32 and the second conducting wire 31, so as to reduce a risk of breakage of the joint of the second shell assembly 32 and the second conducting wire 31, and further improve reliability of the second connector 30. The second connecting housing 324 may be formed by an injection molding process, or the second connecting housing 324 may be a part of the second outer housing 322, which is not limited herein.

Referring to fig. 5, 7 and 11, fig. 11 is a schematic cross-sectional view of the θ region of the connecting device shown in fig. 2 along the direction I-I.

In an embodiment, one of the first outer housing 222 and the second outer housing 322 is provided with an elastic connection portion 3222, and the other is provided with a locking groove 2222, so that the elastic connection portion 3222 and the locking groove 2222 are used to interfere with the plugging and unplugging processes and the required plugging and unplugging force of the first connector 20 and the second connector 30. When the first connector 20 is connected to the second connector 30, the elastic connection portion 3222 is embedded in the fastening groove 2222, so as to facilitate reliable connection therebetween, and reduce the risk of disengagement between the first connector 20 and the second connector 30.

That is, when the first connector 20 is connected to the second connector 30, the first shell 222 has an elastic connection portion 3222 on a side facing the second shell 322, and the second shell 322 has a locking groove 2222 on a side facing the first shell 222. Or, a fastening groove 2222 is disposed on a side of the first outer housing 222 facing the second outer housing 322, and an elastic connecting portion 3222 is disposed on a side of the second outer housing 322 facing the first outer housing 222.

As exemplarily illustrated in fig. 11, the elastic connection portion 3222 is disposed on a side of the second housing 322 facing away from the second interface slot 321 (as shown in fig. 7). The locking slot 2222 is disposed on a side of the first outer housing 222 facing the first interface slot 221 (as shown in fig. 5).

Specifically, the elastic connection portion 3222 includes a first inclined surface α and a second inclined surface β inclined with respect to the preset direction X. The first slope α and the second slope β are connected and form a protrusion facing away from the interface slot 421. Wherein the predetermined direction X is parallel to the axial direction of the second housing assembly 32. The elastic connection portions 3222 can be elastically deformed to allow the first connector 20 to move relative to the second connector 30 during the connection and disconnection of the first connector 20 and the second connector 30.

The first inclined surface α is away from the junction of the second wire 31 and the second housing 322 relative to the second inclined surface β. When the first connector 20 is connected to the second connector 30, the first inclined surface α and/or the second inclined surface β abut against the groove wall of the engagement groove 2222.

Optionally, the first inclined surface α is inclined at a smaller angle with respect to the preset direction X than the second inclined surface β is inclined with respect to the preset direction X. It is easily understood that the first inclined surface α is first protruded into the second connector 30 to be contacted when the first connector 20 and the second connector 30 are assembled. When the inclination angle of the first slope α is small, it is advantageous for the user to be able to assemble the first connector 20 and the second connector 30 with a small force. When the first connector 20 is separated from the second connector 30, the second inclined surface β abuts against one side of the engagement groove 2222 close to the first connector 20, and the second inclined surface β is inclined relatively greatly, so that the first connector 20 and the second connector 30 can be prevented from being easily separated, the pull-out force required when the first connector 20 is separated from the second connector 30 is increased, and the risk that the first connector 20 cannot be reliably connected with the second connector 30 is reduced.

Further, the outer surface of the second limiting shell 323 can be further provided with a limiting part protruding towards the first outer shell, so that when the second limiting shell 323 is assembled with the second outer shell 322, the limiting part can be embedded into one side of the elastic connecting part 3222 facing the second limiting shell 323, thereby facilitating reliable assembly of the second limiting shell 323 and the second outer shell 322 and reducing the risk of separation of the second limiting shell 323 and the second outer shell 322.

Referring to fig. 5, 7, 10 and 12, fig. 12 is a schematic cross-sectional view of the second connector shown in fig. 6 with the second conductive wires omitted along the direction J-J.

Specifically, the body portion 3231 may abut against a surface of the body portion 2231 without the step portion 2232, or the body portion 3231 may be close to a surface of the body portion 2231 without the step portion 2232, so that the male terminal 231 of the first connector 20 can be connected to the female terminal 332 of the second connector 30 in an opposite manner, that is, the male terminal 231 of the first connector 20 is butted against the female terminal 332 of the second connector 30. The stepped portion 2232 is fitted into the mating groove 3232 so that the male terminal 331 of the second connector 30 protrudes into the mating groove 3232, so that the female terminal 232 of the first connector 20 can be mated with the male terminal 331 of the second connector 30. The main body 2231 and the step 2232 of the first connector 20, and the main body 3231 and the mating groove 3232 of the second connector 30 can further play a role of fool-proofing, which is beneficial to the connection between the first connector 20 and the second connector 30 in a correct connection manner, and improves the connection efficiency between the first connector 20 and the second connector 30.
