[0028] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0029] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0030] like Figure 1-7 As shown in the figure, one embodiment of the present invention is a connector, which includes a sheath 1, a terminal mounting sleeve 2 installed in the sheath 1, and a terminal 3 installed in the terminal mounting sleeve 2.

[0031] like Figure 1-3 As shown, the terminal mounting sleeve 2 has a first through hole 21 on at least one side at the terminal 3 position. The terminal 3 has a first elastic arm 31 on its side that cooperates with the first through hole 21. When the terminal 3 is inserted into the cavity 26 of the terminal mounting sleeve 2 in the installation direction A but not fully inserted, the first elastic arm 31 abuts against the inner wall of the terminal mounting sleeve 2 and is compressed and radially retracts. When the terminal 3 is fully inserted and the first elastic arm 31 is aligned with the first through hole 21, the first elastic arm 31 releases its elastic force and extends into the first through hole 21, so that the first through hole 21 and the first elastic arm 31 together limit the terminal 3, preventing the terminal 3 from moving backward in the disassembly direction B, thereby improving the safety of the automotive circuit connection.

[0032] like Figure 1 , 2 As shown, in a preferred embodiment of the present invention, the terminal 3 is cylindrical, and a second through hole is provided on the side wall of the terminal 3. One end of the first elastic arm 31 is fixedly connected to or integrally formed with one side wall of the second through hole.

[0033] In the initial state, the first elastic arm 31 has an angle of 20-60 degrees with the main body of the terminal 3. When the terminal 3 is inserted into the terminal mounting sleeve 2, the angle between the first elastic arm 31 and the main body of the terminal 3 shrinks to 0-10 degrees. When the terminal 3 is inserted into place, the first elastic arm 31 is aligned with the first through hole 21. Under the action of elastic force, the end of the first elastic arm 31 facing the disassembly direction B extends into the first through hole 21 and abuts against the side wall of the first through hole 21 facing the installation direction A, thereby preventing the terminal 3 from retracting in the disassembly direction B.

[0034] like Figure 1-3 As shown, in a preferred embodiment of this utility model, the terminal mounting sleeve 2 is provided with a second elastic arm 22 matching the number of terminals 3. When the terminal mounting sleeve 2 is inserted into the sheath 1, the outer wall surface of the second elastic arm 22 abuts against the inner wall surface of the sheath 1 and retracts into the terminal mounting sleeve 2, and the end of the second elastic arm 22 facing the installation direction A abuts against the end of the terminal 3 facing the disassembly direction B. In this way, the first through hole 21 and the first elastic arm 31 cooperate to form the first anti-backward limit for the terminal 3; the abutment of the end of the second elastic arm 22 facing the installation direction A and the end of the terminal 3 facing the disassembly direction B forms the second anti-backward limit for the terminal 3, thereby further improving the stability and safety of the circuit connection.

[0035] Of course, the end of the second elastic arm 22 facing the installation direction A is not limited to being completely in contact with the end of the terminal 3 facing the disassembly direction B. It can also be that there is a micro gap of about 1 mm between the end of the second elastic arm 22 facing the installation direction A and the end of the terminal 3 facing the disassembly direction B. This micro gap is the safe range of motion of the terminal 3. When the terminal 3 moves within this safe range of motion, there will be no signal circuit disconnection or poor contact.

[0036] like Figure 3 As shown, in a preferred embodiment of the present invention, the terminal mounting sleeve 2 has a third through hole 23 on at least one side, and the second elastic arm 22 is fixedly connected to or integrally formed with one side wall of the third through hole 23 at one end facing the disassembly direction B. The second elastic arm 22 can move inside and outside the third through hole 23.

[0037] like Figure 1-3 As shown, in a preferred embodiment of the present invention, the second elastic arm 22 is provided with a protrusion 221 at one end in the installation direction A, and the protrusion 221 is configured to abut against the inner wall of the sheath 1.

[0038] When the terminal mounting sleeve 2 is inserted into the sheath 1, the inner wall of the sheath 1 presses the protrusion 221 towards the cavity of the terminal mounting sleeve 2, so as to press the second elastic arm 22 into the cavity of the terminal mounting sleeve 2, thereby achieving the contact between the second elastic arm 22 and the terminal 3.

[0039] like Figure 1-3 As shown, in a preferred embodiment of this utility model, the contact surface of the protrusion 221 is arc-shaped, which improves the smoothness of insertion and avoids jamming.

[0040] like Figure 4-8 As shown, in a preferred embodiment of this utility model, the inner wall of the sheath 1 is provided with a first limiting part 11 for limiting the installation direction A and the disassembly direction B of the terminal mounting sleeve 2. The side wall of the terminal mounting sleeve 2 is provided with a second limiting part 24 that cooperates with the first limiting part 11. When the terminal mounting sleeve 2 is installed in place, the second limiting part 24 abuts against the first limiting part 11, and the second limiting part 24 and the first limiting part 11 are interlocked to limit the terminal mounting sleeve 2 and the terminal 3, so as to avoid the terminal 3 from being displaced due to the displacement of the terminal mounting sleeve 2, and further improve the stability and safety of the circuit connection.

[0041] like Figure 4-7 As shown, in a preferred embodiment of the present invention, the first limiting part 11 includes a first abutting part 111 for limiting the installation direction A of the terminal mounting sleeve 2 and a second abutting part 112 for limiting the disassembly direction B of the terminal mounting sleeve 2. The second limiting part 24 includes a third abutting part 241 that cooperates with the first abutting part 111 and a fourth abutting part 242 that cooperates with the second abutting part 112.

[0042] When the terminal mounting sleeve 2 is installed in place, the end of the third abutment 241 facing the installation direction A abuts against the end of the first abutment 111 facing the disassembly direction B, thereby blocking the terminal mounting sleeve 2 in the A direction; the end of the fourth abutment 242 facing the disassembly direction B abuts against the end of the second abutment 112 facing the installation direction A, thereby blocking the terminal mounting sleeve 2 in the B direction, thus fixing the terminal mounting sleeve 2 in the preset working position.

[0043] like Figure 4 , 5 As shown in Figures 7 and 8, in a preferred embodiment of this utility model, the inner wall of the sheath 1 is provided with a guide groove 12, the first abutment 111 is the side wall of the guide groove 12 facing the disassembly direction B, and the third abutment 241 is a first protrusion fixed to the terminal mounting sleeve 2 and corresponding to the guide groove 12. The first protrusion can slide in the guide groove 12. When the third abutment 241 is inserted into the guide groove 12, the position of the fourth abutment 242 corresponds to the position of the second abutment 112, so as to facilitate alignment and improve the circuit connection efficiency.

[0044] like Figure 4-7 As shown, in a preferred embodiment of the present invention, the second abutment 112 includes a second protrusion 1121 and a third protrusion 1122, which are respectively disposed on the two side walls of the cavity of the sheath 1.

[0045] The fourth abutment 242 includes a fourth protrusion 2421 and a fifth protrusion 2422. The fourth protrusion 2421 and the fifth protrusion 2422 are respectively disposed on both sides of the terminal mounting sleeve 2. When the terminal mounting sleeve 2 is installed in place, the fourth protrusion 2421 abuts against the side facing disassembly and the second protrusion 1121 abuts against the side facing the installation direction A, and the fifth protrusion 2422 abuts against the side facing disassembly and the third protrusion 1122 abuts against the side facing the installation direction A, thereby limiting the disassembly direction of the terminal mounting sleeve 2.

[0046] like Figure 6-7 As shown, in a preferred embodiment of this utility model, the second protrusion 1121 and the third protrusion 1122 are inclined surfaces facing the disassembly direction B, and the fourth protrusion 2421 and the fifth protrusion 2422 are inclined surfaces facing the installation direction A, so as to facilitate the sliding of the terminal mounting sleeve 2 towards the installation direction A.

[0047] like Figure 1-3 As shown, in a preferred embodiment of this utility model, the sheath 1 has a fourth through hole 13, and the terminal mounting sleeve 2 has an elastic protrusion 25 at the end located in the disassembly direction B. When the terminal mounting sleeve 2 is fully inserted into the sheath 1, the inner arm of the sheath 1 compresses the elastic protrusion 25. When the terminal mounting sleeve 2 is installed in place, the elastic protrusion 25 aligns with the fourth through hole 13, and the elastic protrusion 25 extends into the fourth through hole 13, thereby further limiting the terminal mounting sleeve 2.

[0048] This invention also provides a vehicle that includes the aforementioned connector. By employing the connector described above, the vehicle of this invention achieves improved circuit connection stability and safety.
