Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Chinese Patent Application No. CNCN202410446142.4, filed on April 12, 2024, with the State Intellectual Property Office of China, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a connector and a connector assembly including the connector. [Background technology]

[0003] In the prior art, a high-voltage connector typically includes a housing and a high-voltage module and a low-voltage module disposed within the housing. The high-voltage module is adapted to be fastened to a high-voltage mating module in a high-voltage mating connector and electrically connected thereto. The low-voltage module is adapted to be electrically connected to a low-voltage mating module in the high-voltage mating connector. In the prior art, to prevent arcing when the high-voltage module is electrically connected to the high-voltage mating module, it is necessary to supply power to the high-voltage module and the high-voltage mating module only after the high-voltage module is fastened to the high-voltage mating module.

[0004] In the prior art, it is typically determined whether a high-voltage module is fastened to a high-voltage mating module based on the electrical connection between the low-voltage module and the low-voltage mating module. If the low-voltage module and the low-voltage mating module are electrically isolated, the high-voltage module is determined to be unfastened to the high-voltage mating module, and if the low-voltage module is electrically connected to the low-voltage mating module, the high-voltage module is determined to be fastened to the high-voltage mating module. However, in the prior art, the high-voltage module and the low-voltage module move synchronously. During the fastening process of the high-voltage module and the high-voltage mating module, the low-voltage module also moves synchronously to a position where it is electrically connected to the low-voltage mating module. Therefore, it is difficult to accurately determine whether the high-voltage module is fastened to the high-voltage mating module based on the electrical connection state between the low-voltage module and the low-voltage mating module, which may lead to incorrect judgments and affect the safety of using the connector.

[0005] In the prior art, a high-voltage module typically includes fasteners suitable for threaded connection with a high-voltage mating module, which fasten the high-voltage module to the high-voltage mating module to achieve electrical connection between the high-voltage module and the high-voltage mating module. In the prior art, visual inspection is typically used to prevent forgetting to tighten the fasteners. However, it is difficult to accurately visually check whether the fasteners are tightened, which can easily lead to errors and can still pose a risk of the fasteners not being tightened. Therefore, the method of visually inspecting whether the fasteners are tightened has problems of insufficient accuracy and low inspection efficiency. If the fasteners are not tightened, it can lead to failure of the high-voltage connection product and even cause a safety accident. Summary of the Invention [Problem to be solved by the invention]

[0048] As shown in FIGS. 1 to 10 , an exemplary embodiment of the present invention discloses a connector 1. The connector 1 includes a housing 10, a high-voltage module 11, a low-voltage module 12, and a locking component 13. The housing 10 is adapted to be mated with a mating housing 20 of a mating connector 2. The high-voltage module 11 is mounted in the housing 10 and adapted to be fastened to a high-voltage mating module 21 of the mating connector 2 to be electrically connected to the high-voltage mating module 21. The low-voltage module 12 is movably mounted on the outside of the housing 10. The locking component 13 is rotatably mounted on the outside of the housing 10. When the high-voltage module 11 is not fastened to the high-voltage mating module 21, the locking elements 13 are restricted by the high-voltage module 11 to a locked position engaged with the low-voltage module 12, locking the low-voltage module 12 in a pre-installation position separated from the low-voltage mating module 22 of the mating connector 2. When the high-voltage module 11 is fastened to the high-voltage mating module 21, the locking elements 13 are rotatable to an unlocked position separated from the low-voltage module 12, allowing the low-voltage module 12 to be moved to a final installation position in which it is electrically connected to the low-voltage mating module 22.

[0049] 1 to 10 , in the illustrated embodiment, the low-voltage module 12 can be independently moved to a final installation position where it is electrically connected to the low-voltage mating module 22 only after the high-voltage module 11 is fastened to the high-voltage mating module 21. Therefore, the present invention can accurately determine whether the high-voltage module 11 is fastened to the high-voltage mating module 21 based on the electrical connection status between the low-voltage module 12 and the low-voltage mating module 22, thereby effectively avoiding erroneous determination and improving the safety of the connector 1.

[0050] 1 to 10 , in the illustrated embodiment, when the high-voltage module 11 is not fastened to the high-voltage mating module 21, the locking components 13 cannot be rotated from the locked position to the unlocked position. The locking components 13 can be rotated from the locked position to the unlocked position only when the high-voltage module 11 is fastened to the high-voltage mating module 21. Therefore, the present invention allows the locking components 13 to accurately check whether the high-voltage module 11 is fastened to the high-voltage mating module 21, improving the accuracy and efficiency of the inspection and effectively preventing the problem of forgetting to fasten the high-voltage module 11.

[0051] 1 to 10, in the illustrated embodiment, the locking components 13 are used to detect whether the high-voltage module 11 is fastened to the high-voltage mating module 21. When the high-voltage module 11 is not fastened to the high-voltage mating module 21, the high-voltage module 11 is in a position that interferes with the locking components 13, and therefore the locking components 13 cannot rotate from the locked position to the unlocked position. When the high-voltage module 11 is fastened to the high-voltage mating module 21, the high-voltage module 11 is in a position that does not interfere with the locking components 13, and the locking components 13 can rotate from the locked position to the unlocked position.

[0052] As shown in FIGS. 1 to 10 , in the illustrated embodiment, the high-voltage module 11 includes a fastener 110 suitable for threaded connection with the high-voltage mating module 21. The fastener 110 is used to fasten the high-voltage module 11 to the high-voltage mating module 21 to establish an electrical connection between the high-voltage module 11 and the high-voltage mating module 21. When the fastener 110 is not tightened to the high-voltage mating module 21, the outer end 11 a of the fastener 110 exposed from the housing 10 presses against the locking component 13, restricting the locking component 13 to the locked position; therefore, the locking component 13 cannot rotate from the locked position to the unlocked position. When the fastener 110 is tightened to the high-voltage mating module 21, the outer end 11 a of the fastener 110 moves to a position that does not interfere with the locking component 13, allowing the locking component 13 to rotate from the locked position to the unlocked position.

[0053] 1 to 10 , in the illustrated embodiment, the high-voltage module 11 includes a plurality of fasteners 110, and the locking component 13 is used to simultaneously detect whether the plurality of fasteners 110 are fastened to the high-voltage mating module 21. If any one of the plurality of fasteners 110 is not fastened to the high-voltage mating module 21, the locking component 13 cannot be rotated from the locked position to the unlocked position. Only when all of the plurality of fasteners 110 are fastened to the high-voltage mating module 21, can the locking component 13 be rotated from the locked position to the unlocked position.

[0054] As shown in Figures 1 to 10, in the illustrated embodiment, when fastener 110 is fastened to high-voltage mating module 21, outer end 11a of fastener 110 is in a position that does not interfere with locking component 13, allowing locking component 13 to rotate from the locked position to the unlocked position.

[0055] As shown in FIGS. 1 to 10 , in the illustrated embodiment, the locking component 13 includes a pair of side arms 131 and a top cover 130. One end of the pair of side arms 131 is rotatably connected to each side of the housing 10. The top cover 130 is connected between the other ends of the pair of side arms 131. When the fastener 110 is not fastened to the high-voltage mating module 21, the outer end 11 a of the fastener 110 abuts against the top cover 130 of the locking component 13, preventing the locking component 13 from rotating from the locked position to the unlocked position. When the fastener 110 is fastened to the mating connector 2, the outer end 11 a of the fastener 110 does not interfere with the top cover 130 of the locking component 13, allowing the locking component 13 to rotate from the locked position to the unlocked position.

[0056] 1 to 10, in the illustrated embodiment, a pivot hole 132 is formed at one end of each of a pair of side arms 131, and a protruding pivot shaft 102 is formed on each side of the housing 10. The pivot shaft 102 rotatably engages with the pivot hole 132, allowing the locking component 13 to rotate around the pivot shaft 102.

[0057] 1-10 , in the illustrated embodiment, outer end 11a of fastener 110 is adapted to engage with an operating tool (not shown) to enable fastener 110 to be tightened or loosened via the operating tool engaged with outer end 11a. When locking component 13 is in the locked position, outer end 11a of fastener 110 is exposed outside top cover 130 of locking component 13, enabling the operating tool to engage outer end 11a of fastener 110 to tighten or loosen fastener 110.

[0058] As shown in Figures 1 to 10, in the illustrated embodiment, when the locking component 13 is rotated to the unlocked position, the outer end 11a of the fastener 110 is hidden by the top cover 130 of the locking component 13, and therefore the operating tool cannot engage with the outer end 11a of the fastener 110, preventing the tightened fastener 110 from being accidentally loosened by the operating tool.

[0059] 1 to 10 , in the illustrated embodiment, the high-voltage module 11 further includes a high-voltage cable 111 and a high-voltage terminal 112.
