Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1, as Figure 1 and Figure 2As shown, a high-voltage connector socket includes a socket shell, the socket shell 1 includes a flange shell 2 and a terminal body 3 arranged inside the flange shell 2, the flange shell 2 and the terminal body 3 are connected as one body, an inner cavity hole 6 is provided on the terminal body 3, a shielding shell assembly 4 is provided on the outside of the terminal body 3, a terminal 5 is inserted in the inner cavity hole 6, and a position determination structure matched with the terminal body 3 is provided on the outside of the terminal body 3. A position determination structure is provided on the path of the terminal inserted into the inner cavity hole, and the position determination structure is used to directly display whether the terminal is installed in place, avoiding the situation that it is not possible to directly determine whether the terminal is installed in place when the shielding shell assembly is blocked, and solving the technical problem that it is unclear whether the terminal is installed in place when the shielding shell assembly is blocked.

[0028] Embodiment 2, on the basis of embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, a high-voltage connector socket, the position determination structure includes TPA8 and cantilever 7, an open slot is provided on the terminal body 3, the cantilever 7 is arranged in the open slot, a limiting hole 9 is provided between the flange housing 2 and the terminal body 3, the TPA8 is located on the terminal body 3, the limiting hole 9 is connected with the inner cavity hole 6 through the open slot, one end of the cantilever 7 is connected to the slot wall of the open slot, and the other end extends into the inner cavity hole 6, when the terminal 5 is inserted into the inner cavity hole 6, the TPA8 can be inserted into the limiting hole 9 and the TPA8 is engaged with the terminal body 3; when the terminal 5 is inserted into the inner cavity hole 6 and is not inserted into the position, the terminal 5 squeezes the cantilever 7 into the limiting hole 9, and the part of the TPA8 inserted into the limiting hole 9 is stopped by the cantilever 7. The setting of the open slot is to realize that one end of the cantilever 7 is fixed to the slot wall, and the other end can extend into the inner cavity hole 6 along the open slot or be squeezed into the limiting hole 9 by the terminal 5. The flange housing 2 and the terminal body 3 are integrally connected via a connecting block 17, which is located in the limiting hole 9. Preferably, four connecting blocks 17 are symmetrically arranged in the limiting hole 9, and the flange housing 2 and the terminal body 3 are integrally connected via the connecting blocks 17. TPA8 refers to a circuit connection element on a connector, which can connect or disconnect a circuit without damaging cables or equipment. It is usually composed of a metal shell, pins and a plug, and has waterproof, wear-resistant and other properties. TPA is mainly used to ensure accurate transmission and stable connection of connector circuits.

[0029] Embodiment 3, on the basis of embodiment 2, as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a high voltage connector socket, the limiting hole 9 is arranged along the direction of the inner cavity hole 6 into which the terminal 5 is inserted. It is ensured that the direction in which the TPA 8 is inserted into the limiting hole 9 is consistent with the direction in which the terminal 5 is inserted into the inner cavity hole 6, and the limiting hole 9 is further limited.

[0030] Embodiment 4, on the basis of embodiment 3, as Figure 6 and Figure 7 As shown, a high-voltage connector socket, the terminal body 3 is provided with a slot 10, the TPA8 is provided with a fixing block 11, and the fixing block 11 is engaged with the slot 10. The fixing block 11 is engaged with the slot 10 to clamp the TPA8 on the terminal body 3, which is conducive to improving the connection firmness between the TPA8 and the terminal body 3.

[0031] Embodiment 5, on the basis of embodiment 4, as Figure 5 , Figure 6 and Figure 7 As shown, a high-voltage connector socket, the terminal 5 includes a box body part and a wire connection part, the box body part and the wire connection part are connected as one piece, and a recessed area is provided between the box body part and the wire connection part. When the terminal 5 is inserted along the inner cavity hole 6 and is not plugged into place, the box body part squeezes the cantilever 7 into the limiting hole 9, and the part of the TPA8 inserted into the limiting hole 9 is stopped by the cantilever 7; when the terminal 5 is inserted into place along the inner cavity hole 6, the recessed area is adapted to the cantilever 7, the TPA8 can be inserted into the limiting hole 9, and the TPA8 is clamped with the terminal body 3. The setting of the recessed area is to ensure that the box body part of the terminal 5 is installed in place, avoiding the situation that the terminal 5 is not installed in place. When the box body is not installed in place, the box body is always in a state of squeezing the cantilever 7, squeezing the cantilever 7 into the limiting hole 9, so that the part of TPA8 inserted into the limiting hole 9 is blocked by the cantilever 7, and TPA8 and the terminal body 3 cannot be clamped. Even when the shielding shell assembly is blocked, it can intuitively show that the box body is not installed in place, which solves the technical problem of whether the terminal is installed in place when the shielding shell assembly is blocked.

[0032] Embodiment 6, embodiment 6, on the basis of embodiment 5, as Figure 6 and Figure 7 As shown, a high-voltage connector socket, the suspended end of the cantilever 7 is provided with a protrusion 12, the setting of the protrusion 12 is equivalent to increasing the thickness of the suspended end of the cantilever 7, so that the cantilever 7 can provide a more stable support, the protrusion 12 is located on the path of the terminal 5 inserted into the inner cavity hole 6, when the terminal 5 is inserted into place along the inner cavity hole 6, the recessed area is adapted to the protrusion 12 and the top surface of the protrusion 12 is blocked and matched with the bottom surface of the box part. The protrusion 12 and the cantilever 7 are integrally connected to form an inverted L-shaped structure, the setting of the inverted L-shaped structure makes it easy for the box part of the terminal 5 to squeeze the cantilever 7 into the limiting hole 9, and at the same time, when the terminal 5 is inserted into place along the inner cavity hole 6, the top surface of the protrusion 12 is blocked and matched with the bottom surface of the box part, which provides additional holding force for the terminal 5 to be installed in the socket shell 1, and increases the holding force of the terminal 5 installed in the socket shell 1.

[0033] When implementing Example 6, the socket shell 1, the shielding shell assembly 4, the terminal 5 and the TPA8 are first formed in sequence, and then the tail of the shielding shell assembly 4 is first extended from the top of the socket shell 1, and the shielding shell assembly 4 is extended along the limiting hole 9. At this time, the connecting block 17 is inserted into the connecting slot 18. After the shielding shell assembly 4 is extended along the limiting hole 9, the terminal 5 is inserted along the inner cavity hole 6, and then the TPA8 is inserted along the limiting hole 9. At this time, if the TPA8 can be fully inserted into the limiting hole 9 and the fixing block 11 on the TPA8 is snap-fitted with the slot 10 on the terminal body 3, it indicates that the terminal 5 is installed in place in the inner cavity hole 6; if the TPA8 cannot be fully inserted into the limiting hole 9 and If the fixing block 11 on TPA8 and the slot hole 10 on the terminal body 3 are not snap-fitted, it means that the terminal 5 is not installed in place in the inner cavity hole 6. At this time, the box part of the terminal 5 is in a state of squeezing the cantilever 7, and the cantilever 7 is squeezed into the limiting hole 9, so that the part of TPA8 inserted into the limiting hole 9 is blocked by the cantilever 7, and TPA8 and the terminal body 3 cannot be snap-fitted. At this time, it is necessary to pull TPA8 out of the limiting hole 9, reinsert the terminal 5 into the inner cavity hole 6, and then continue to reinstall TPA8 until TPA8 can be fully inserted into the limiting hole 9 and the fixing block 11 on TPA8 and the slot hole 10 on the terminal body 3 are snap-fitted.

[0034] Embodiment 7, on the basis of any one of Embodiments 2 to 6, as Figure 5 , Figure 6 and Figure 7 As shown, a high-voltage connector socket, the portion of the TPA8 inserted into the limiting hole 9 is located between the terminal body 3 and the shielding shell assembly 4, and the shielding shell assembly 4 is clamped on the terminal body 3. The shielding shell assembly 4 is provided to prevent electromagnetic interference radiation from entering or leaking, so as to avoid affecting the normal operation of the terminal 5 in the terminal body 3. The shielding shell assembly 4 is clamped on the terminal body 3, which improves the connection strength of the shielding shell assembly 4 on the socket housing 1.

[0035] Embodiment 8, on the basis of embodiment 7, as Figure 5 , Figure 6 and Figure 7 As shown, a high-voltage connector socket, the shield shell assembly 4 includes a body 13, the body 13 is sleeved on the outside of the terminal body 3, and the body 13 is provided with a side spring thorn 14, one end of the side spring thorn 14 is connected to the body 13, and the other end is suspended and extends into the body 13, and the part of the side spring thorn 14 extending into the body 13 abuts against the terminal body 3. The setting of the side spring thorn 14 further improves the connection strength between the body 13 and the terminal body 3. Preferably, the side spring thorn 14 is located in the middle of the body 13.

[0036] Embodiment 9, on the basis of embodiment 8, as Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a high-voltage connector socket, the body 13 is provided with a hook-shaped elastic arm 16. It should be noted that the body 13 of the shielding shell assembly 4 of the present application is relatively long, and the hook-shaped elastic arm 16 is located at the tail of the body 13. During installation, the tail of the body 13 extends from the top of the socket shell 1 and extends along the limiting hole 9. The body 13 covers the outside of the entire terminal body 3 to ensure that the shielding shell assembly 4 has sufficient coverage area to improve the electromagnetic shielding effectiveness. A connecting slot 18 is provided on the body 13 of the shielding shell assembly 4. When the tail of the body 13 extends from the top of the socket shell 1 and extends along the limiting hole 9, the connecting block 17 is inserted into the connecting slot 18, thereby avoiding the situation where the connecting block 17 affects the tail of the body 13 from extending from the top of the socket shell 1 and extending along the limiting hole 9. Preferably, the main body 13 is a quadrilateral structure, and two hook-shaped elastic arms 16 are symmetrically arranged on the four sides of the main body 13, that is, eight hook-shaped elastic arms 16 are provided on the main body 13. When the shielding shell assembly 4 contacts the installation interface 19, the hook-shaped elastic arm 16 is first compressed, and the compressed hook-shaped elastic arm 16 is inserted into the socket of the installation interface 19, and then the hook-shaped elastic arm 16 restores its deformation and abuts against the installation interface 19. The provision of eight hook-shaped elastic arms 16 effectively increases the contact points between the shielding shell assembly 4 and the installation interface 19, thereby improving the contact resistance.

[0037] Embodiment 10, on the basis of embodiment 8 or 9, as Figure 5 , Figure 6 and Figure 7 As shown, a high-voltage connector socket, the body 13 is provided with a long strip protrusion 15, one end of the long strip protrusion 15 is connected to the body 13, and the other end is suspended. The suspended end of the long strip protrusion 15 is located in the flange housing 2. Preferably, the long strip protrusion 15 is located at the top of the body 13, and 6 long strip protrusions 15 are symmetrically arranged on the top of the body 13. The long strip protrusion 15 is a lever structure with a long force arm. During the plugging process of the socket and the plug, the long strip protrusion 15 can maintain good contact between the shielding shell of the socket and the plug under a small pressure, avoiding the yielding of the structural material due to excessive force on the contact point, resulting in unstable connection between the contact points, thereby causing contact failure. This structure effectively improves the contact resistance and ensures the continuity of the connector shielding connection.
