[0002] With increasing global awareness of environmental protection and the transformation of energy structures, the new energy vehicle industry has ushered in unprecedented development opportunities. As one of the core components of new energy vehicles, the performance of high-voltage connector assemblies directly affects the safe operation and energy efficiency of the entire vehicle. However, traditional connector assemblies lack the ability to seal the socket independently. In certain special application environments, external moisture can enter the equipment through gaps in the socket, causing equipment malfunction. Therefore, developing a socket with a sealing function is essential.

[0003] Existing right-angle high-voltage connector sockets have the following drawbacks: 1. Existing right-angle high-voltage connector sockets have significant gaps between the power terminals and the socket housing, preventing a proper seal between the device cavity and the external environment. 2. Existing right-angle high-voltage connector sockets have significant gaps between the signal terminals and the socket housing, preventing a proper seal between the device cavity and the external environment. 3. Existing right-angle high-voltage connector sockets have significant gaps between the shield and the socket housing, preventing a proper seal between the device cavity and the external environment. This allows external air and moisture to enter the device through these gaps, leading to device failure. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model proposes a bent-type single-seat sealed high-voltage connector, which solves the problem that in the prior art, there are many gaps between the shielding layer and the socket housing of the bent-type high-voltage connector socket, which may allow external air and moisture to enter the equipment and cause equipment failure.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A bent-type single-seat sealed high-voltage connector includes a socket housing assembly and a rear insulator inserted into the socket housing assembly.

[0007] Furthermore, the socket housing assembly includes a socket housing and a signal terminal disposed within the socket housing, and the signal terminal is injection molded integrally with the socket housing.

[0012] Furthermore, a matching snap-fit ​​block and snap-fit ​​interface are provided between the signal terminal housing and the rear insulator.

[0013] Furthermore, the outer end of the shielding layer is provided with a shielding contact spring.

[0014] Furthermore, the portion of the shielding layer near its outer end is clamped between the rear insulator and the socket housing assembly, and there are corresponding locking blocks and latches between the rear insulator and the shielding layer.

[0018] 2. This utility model achieves a seal between the terminal and the housing by cooperating with the socket sealing ring, the socket housing, and the rear insulator.

[0019] 3. This utility model uses the socket housing, power pins, and signal pins as a single injection molding process, which enables the power circuit to achieve a 90° connection with a single conversion.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1As shown in Embodiment 1 of this utility model, a bent-type single-seat sealed high-voltage connector includes a socket housing assembly 1 and a rear insulator 6 inserted into the socket housing assembly 1. A shielding layer 2 is embedded in the socket housing assembly 1. In this embodiment, the socket housing assembly 1 includes a socket housing and terminals disposed within the socket housing. The socket housing is injection molded, and the terminals are injection molded integrally with the socket housing. A gap is reserved in the socket housing for the insertion of the shielding layer 2. This gap leads to the insertion end of the socket housing assembly 1, which can easily lead to dust and / or water entering the gap. The outer end of the shielding layer 2, i.e., the end away from the insertion end of the socket housing assembly 1, is located between the rear insulator 6 and the socket housing assembly 1. The end faces of the rear insulator 6 and the socket housing 1 are respectively provided with an interface rubber ring 4 and an interface rubber ring 5 protruding from the end faces. Interface ring 4 and interface ring 5 are annular sealing rings. When the connector is installed on the mounting panel of the equipment, interface ring 4 and interface ring 5 form a closed space between the socket housing assembly 1 and the mounting panel, sealing water and / or dust that may enter through gaps within this space and preventing water and / or dust from entering the equipment. The tail of the rear insulator 6 mates with the socket housing, and a socket sealing ring 3 is provided between the tail of the rear insulator 6 and the socket housing. The socket sealing ring, the socket housing, and the rear insulator cooperate with each other to achieve a seal between the terminal and the housing, thereby achieving a complete seal for the high-voltage connector.

[0030] Example 2 differs from Example 1 in that, as Figure 3 As shown, the socket housing assembly 1 includes a socket housing and a signal terminal 11 disposed inside the socket housing, and the signal terminal 11 is injection molded integrally with the socket housing.

[0031] Furthermore, the socket housing is provided with a signal terminal dispensing cavity 7, which is located at the joint gap between the signal terminal 11 and the socket housing. By injecting sealant into the signal terminal dispensing cavity 7, the gap between the signal terminal 11 of the metal part and the socket housing of the plastic part after the socket housing assembly is injection molded is sealed due to thermal expansion and contraction.

[0032] Example 3 differs from Example 2 in that, as Figure 4 As shown, the socket housing is provided with a power terminal 9, and the power terminal 9 is injection molded into the socket housing.

[0033] Furthermore, the socket housing is provided with a power terminal dispensing cavity 8, which is located at the joint gap between the power terminal 9 and the socket housing. By injecting sealant into the power terminal dispensing cavity 8, the gap between the power terminal 9 of the metal part and the socket housing of the plastic part after the socket housing assembly is injection molded is sealed due to thermal expansion and contraction.

[0034] Example 4 differs from Example 3 in that, as Figure 2 and 3 As shown, a signal terminal housing 10 is inserted into the rear insulator 6, and the rear end of the signal terminal housing 10 is provided with a socket for the signal terminal 11 to be inserted.

[0035] Furthermore, a matching snap-fit ​​block and a snap-fit ​​interface are provided between the signal terminal housing 10 and the rear insulator 6. In this embodiment, protruding snap-fit ​​blocks are provided on both sides of the signal terminal housing 10, one side of which is a slope. A snap-fit ​​interface that mates with the snap-fit ​​block is provided at the corresponding position of the rear insulator 6 so that the snap-fit ​​block can be inserted and locked in place.

[0036] Example 5 differs from Example 4 in that, as Figure 2 and 4 As shown, the rear insulator 6 is provided with two power terminal cavities, and the rear end of the power terminal cavity is provided with a socket for the power terminal 9 to be inserted.

[0037] Furthermore, since the two power terminals 9 are located on both sides of the signal terminal 11, the signal terminal housing 10 is inserted between the two cavities. In this embodiment, the two power terminal cavities are connected by two connecting plates on both sides, and the signal terminal housing 10 is inserted between the two connecting plates. The card interface is provided on the connecting plate.

[0038] Example 6 differs from Example 4 in that, as Figure 1 , Figure 2 and 3 As shown, the outer end of the shielding layer 2 is provided with shielding contact springs. In this embodiment, multiple shielding contact springs are arranged adjacently on both sides of the outer end of the shielding layer 2 to form a toothed structure. When the connector is installed on the mounting panel of the device, the shielding contact springs elastically contact the mounting panel, effectively improving the electromagnetic shielding performance while satisfying the single-seat sealing function. In another embodiment, shielding contact springs can be provided on all four sides of the outer end of the shielding layer 2.

[0039] Example 7 differs from Example 6 in that, as Figure 2 , Figure 3 and 4 As shown, Figure 2 As shown, the portion of the shielding layer 2 near its outer end is sandwiched between the rear insulator 6 and the socket housing assembly 1, and the outermost portion of the rear insulator 6 mates with the shielding layer 2. A corresponding locking block and latch are provided between the rear insulator 6 and the shielding layer 2.
