Description

Technical Field

[0001] The present application relates to the technical field of connector interlocking, and specifically discloses a novel high-voltage connector interlocking system for new energy vehicles. Background Art

[0002] As global oil resources become scarce, new energy vehicles are born to meet the needs of human travel and cargo transportation. As the vein of the entire vehicle, the high-voltage wire harness of new energy vehicles carries electrical performance and signal transmission, and new energy plays a very important role. However, before debugging, repairing and powering on the whole vehicle, the high-voltage connector contact condition of the whole vehicle needs to be diagnosed, and the high-voltage wire harness connector of new energy vehicles must have strong interlocking capabilities. Therefore, the interlocking terminals of the high-voltage connectors of new energy vehicles are crucial. In this context, it is necessary to optimize and update a high-voltage connector interlocking terminal structure, which can not only ensure the stability of the high-voltage connector interlocking performance under certain cost advantages, but also improve production efficiency and reduce labor intensity;

[0003] The original high-voltage connector interlocking terminal structure is "flat needle type", the high-voltage connector is easy to loosen after docking, the contact resistance is large, and it is not easy to form a good electrical system transmission. In view of this, the utility model inventor proposed a new type of new energy vehicle high-voltage connector interlocking system. Utility Model Content

[0004] The utility model aims to solve the problem that the traditional interlocking structure is easy to fall off after being connected with the high-voltage connector.

[0005] In order to achieve the above object, the utility model provides the following basic solutions:

[0006] A new type of high voltage connector interlocking system for new energy vehicles, including

[0007] Extruded plastic shell: used to wrap cables;

[0008] The compression core fixed to the compression molded shell is used to wrap the cable and realize the cable routing;

[0009] A rotation fixing assembly connected to the pressure core: after being inserted into the connector, rotation locking is achieved;

[0010] Terminal locking piece: inserted into the connection hole of the connector and initially connected to the connector;

[0011] Several fixing components: arranged on the surface of the terminal locking member, and locking up and down after the connector is inserted;

[0012] Contact terminal: connected to the connector to achieve signal transmission.

[0013] The principles and effects of this basic solution are:

[0014] 1. Compared with the existing technology, this product has a simple structure design: the contact terminal is suitable for high-voltage connectors of various structures, and the cost is low. Low production cost: the original terminal material remains unchanged, and the contact terminal is easier to mass produce, effectively reducing production costs. High-voltage connector power resistors are almost all cylindrical terminal structures, and the contact terminal has a similar structure, which can keep the connector high-voltage terminal structure unified, and the appearance is easier for users to accept.

[0015] 2. Compared with the existing technology, significant improvements have been made in interlocking. This product has both rotational interlocking and up and down interlocking functions. That is, after being connected to the connector, it cannot be rotated or moved up and down. As a result, the connection stability of this device is very high, which solves the problem that the traditional interlocking structure is easy to fall off after being connected to the high-voltage connector.

[0016] 3. Compared with the prior art, in the rotation interlock, a design of changing the size of the rotation fixing component is adopted, and then the rotation fixing component is clamped to the inner wall of the connecting hole to achieve rotation. On this basis, an interlock for up and down movement is designed.

[0017] 4. Compared with the prior art, considering that this product needs to be rotated continuously when inserted into the connector, a fixing component is designed using the centrifugal force generated by the rotation, so that the fixing component can contact the hole wall of the connecting hole after being extended. Considering that the hole walls of most connecting holes are made of metal, a magnetic connection is designed to achieve interlocking of up and down movement.

[0018] 5. Compared with the prior art, the stability of the present device is not only reflected in the interlocking, but also in the unlocking. If the fixed component needs to fail, the fixed component must be rotated first. Only when the rotating fixed component fails first, the fixed component will fail. The failure of the rotating fixed component can be controlled manually. Therefore, the stability of the present device becomes very high, which solves the problem that the traditional interlocking structure is easy to fall off after being connected with the high-voltage connector.

[0019] Furthermore, the rotation fixing assembly, the terminal locking member and the contact terminal are all provided with through grooves, the cable routing is achieved through the through grooves, and the output end of the cable is connected to the contact terminal.

[0020] Furthermore, the contact terminal is a cylindrical probe, and the outer surface of the cylindrical probe is an electrical contact surface connected to the connector.

[0021] Furthermore, the terminal locking piece and the contact terminal have the same shape, both are cylindrical, the radius of the terminal locking piece is larger than the radius of the contact terminal, and the contact terminal is provided with a heat dissipation hole. After the terminals are in contact, they will inevitably generate heat, and then increase in volume, affecting the transmission of electrical performance. The heat dissipation hole can timely conduct the heat to avoid excessive temperature rise, which affects the transmission of electrical performance.

[0022] Furthermore, the rotating fixing assembly includes an inner ring layer fixed to the outer surface of the compression core, a plurality of springs arranged on the outer end surface of the inner ring layer, and an extrusion layer arranged at the output end of the spring. The extrusion layer is fixed with a blocking ring on one side facing the compression-molded shell to prevent the rotating fixing assembly from completely penetrating into the connector connection hole.

[0023] Furthermore, the fixing assembly includes a groove opened on the surface of the terminal locking piece, a spring string symmetrically arranged at the bottom of the groove, a connecting ball arranged at the intersection of the spring string, a support rod fixedly connected to the connecting ball, and a magnetic ball arranged at the free end of the support rod, and the magnetic ball is magnetically connected to the inner wall of the connecting hole.

[0024] Furthermore, a metal rod is provided on the spring string, and a magnetic block is provided on the inner side wall of the groove. After the metal rod and the magnetic block are magnetically connected, the spring string and the support rod form a stable triangle. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A new type of high voltage connector interlocking system for new energy vehicles, including

[0033] The compression molded shell 1 is used to wrap the cable, thereby enabling the subsequent contact terminal 5 to be energized and to connect the contact terminal 5 to the connection hole of the connector.

[0034] The compression core 2 fixedly connected to the compression molded shell 1 is used to wrap the cable and realize the cable routing;

[0035] A rotation fixing component 3 connected to the pressure core 2: after being inserted into the connector, rotation locking is achieved;

[0036] Terminal locking member 4: inserted into the connection hole of the connector and initially connected to the connector;

[0037] Several fixing components: arranged on the surface of the terminal locking member 4, and locked up and down after the connector is inserted;

[0038] Contact terminal 5: connected to the connector to achieve signal transmission.

[0039] Specifically: the rotation fixing component 3 , the terminal locking member 4 and the contact terminal 5 are all provided with a through slot 6 , the cable routing is achieved through the through slot 6 , and the output end of the cable is connected to the contact terminal 5 .

[0040] Specifically: the contact terminal 5 is a cylindrical probe, and the outer surface of the cylindrical probe is an electrical contact surface connected to the connector.

[0041] The terminal locking member 4 and the contact terminal 5 have the same shape, both of which are cylindrical. The radius of the terminal locking member 4 is larger than the radius of the contact terminal 5. The contact terminal 5 is provided with a heat dissipation hole 7. After the terminals are in contact, they will inevitably generate heat, thereby increasing their volume and affecting the transmission of electrical performance. The heat dissipation hole 7 can timely conduct the heat to avoid excessive temperature rise and affect the transmission of electrical performance.

[0042] like Figure 2 As shown, the rotating fixing component 3 includes an inner ring layer 10 fixedly connected to the outer surface of the compression core 2, a plurality of springs 11 arranged on the outer end surface of the inner ring layer 10 and an extrusion layer 9 arranged at the output end of the spring 11, and the extrusion layer 9 is fixedly connected to a blocking ring on the side facing the compression-molded shell 1 to prevent the rotating fixing component 3 from completely penetrating into the connector connection hole.

[0043] like Figure 3As shown, the fixing assembly includes a groove 8 opened on the surface of the terminal locking member 4, a spring string 12 symmetrically arranged at the bottom of the groove 8, a connecting ball 13 arranged at the intersection of the spring string 12, a support rod 14 fixedly connected to the connecting ball 13 and a magnetic ball 15 arranged at the free end of the support rod 14, the magnetic ball 15 is magnetically connected to the inner wall of the connecting hole, a metal rod 16 is also provided on the spring string 12, and a magnetic block 17 is provided on the side inner wall of the groove 8. After the metal rod 16 is magnetically connected to the magnetic block 17, the spring string 12 and the support rod 14 form a stable triangle.

[0044] Specific implementation process:

[0045] In the first step, the terminal locking member 4 is placed into the connection hole, and then the blocking ring is pressed to shrink the extrusion layer 9, and then the terminal locking member 4 is rotated to make the spring string 12 move outwards under the centrifugal force, thereby making the magnetic ball 15 magnetically connected to the hole wall of the connection hole;

[0046] In the second step, after the magnetic ball 15 is magnetically connected to the hole wall of the connection hole, let go so that the extrusion layer 9 contacts the inner wall of the connection hole. At this time, the extrusion layer 9 locks the rotation of the product. After the magnetic ball 15 is magnetically connected to the hole wall of the connection hole, the spring string 12 moves, which connects the magnetic block 17 to the metal rod 16. At this time, the stability of the support rod 14 becomes higher, and then the support rod 14, the spring string 12 and the magnetic ball 15 are used to limit the up and down movement of the product.

[0047] In the third step, the contact terminal 5 is electrically connected to the connector to achieve high voltage detection;

[0048] The fourth step, if you need to remove it, you first need to press the extrusion layer 9. After pressing the extrusion layer 9, you cannot pull it out by force. You can only rotate it first. The rotation will separate the magnetic block 17 from the metal rod 16. When the magnetic block 17 is separated from the metal rod 16, the stability of the support rod 14 will disappear. At this time, the limit of the up and down movement disappears, and then press the extrusion layer 9 to pull out the product.

[0049] The device solves the problem that the traditional interlocking structure is easy to fall off after being connected with the high-voltage connector.
