Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-voltage connector. Background Technology

[0002] Electric compressors are increasingly used in the field of new energy commercial vehicles. Because commercial vehicles operate in harsher environments than passenger cars, new energy heavy trucks, light trucks, and construction machinery often need to travel on unpaved roads, causing electric compressors to withstand significant vibration and impact. When the electric compressor is operating, it requires high-voltage DC power from the vehicle's high-voltage battery through a high-voltage wiring harness connector. Currently, the male and female terminals of the conventional high-voltage connectors are not sealed to the connector housing; they are only secured inside the connector housing with clips. When the vehicle vibrates significantly, the connector cable will shake, causing it to bend at the connector entry point. When the bending angle reaches a certain level, a gap appears between the cable and the connector seal. If it rains or the car is washed, water can enter the connector through this gap and then flow through the metal terminals of the socket into the controller, causing water ingress into the electric compressor and resulting in insulation problems.

[0003] Therefore, there is an urgent need for a high-voltage connector to solve the above problems. Utility Model Content

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 3 As shown, this example provides a high-voltage connector, including a shielding shell 1, terminals 2, a socket housing 3, and a rear cover 4. The socket housing 3 includes a housing portion 31 and a positioning portion 32 located within the housing portion 31. A slot 321 is provided on the positioning portion 32, and the terminals 2 are partially inserted into the slot 321. The shielding shell 1 is disposed within the housing portion 31 and fitted onto the positioning portion 32. The rear cover 4 is disposed on the socket housing 3 and connected to the housing portion 31. The rear cover 4 is fitted around the outer periphery of the terminals 2, and insulating adhesive is filled between the rear cover 4 and the terminals 2. The insulating adhesive is used to fill the gap between the rear cover 4 and the terminals 2 of the high-voltage connector to form a single-end sealed high-voltage connector. This prevents moisture from entering the high-voltage connector and then flowing into the controller via the terminals 2, thereby improving the waterproof rating of the electric compressor controller.

[0039] Optionally, the socket housing 3 includes an upper cover and a lower housing. The lower housing includes a housing portion 31 and a positioning portion 32. The upper cover is disposed on the housing portion 31, and the positioning portion 32 passes through the upper cover and connects to the rear cover 4. A first sealing groove 311 is provided at the connection end where the housing portion 31 abuts against the upper cover. The first sealing groove 311 surrounds the outer periphery of the shielding shell 1. The high-voltage connector also includes a first sealing ring 5, which is disposed within the first sealing groove 311 and sandwiched between the housing portion 31 and the upper cover. The first sealing ring 5 is used to seal the connection between the outer edge of the upper cover and the lower housing of the socket housing 3, preventing moisture from entering the interior of the high-voltage connector through the gap between the outer edge of the upper cover and the lower housing, thereby improving the waterproof performance of the high-voltage connector.

[0040] Optionally, the connecting end is provided with a second sealing groove 312, which surrounds the outer periphery of the positioning part 32 and is located inside the shielding shell 1. The high-voltage connector also includes a second sealing ring 6, which is disposed within the second sealing groove 312 and sandwiched between the shell part 31 and the upper cover. The second sealing ring 6 is used to seal the connection between the inner edge of the upper cover of the socket shell 3 and the lower shell, preventing moisture from entering the interior of the high-voltage connector through the gap between the inner edge of the upper cover and the lower shell, thereby improving the waterproof performance of the high-voltage connector.

[0041] Furthermore, the connecting end of the housing portion 31 is provided with a fixing hole 314, and the upper cover is provided with a through hole corresponding to the fixing hole 314. The high-voltage connector also includes a fastener, which passes through the through hole and is connected to the fixing hole 314 to connect the upper cover and the lower housing. The fastener is used to realize the detachable connection between the upper cover and the lower housing. In a specific implementation, the upper cover is also provided with a through groove through which the positioning portion 32 can pass, so that the terminal 2 in the positioning portion 32 can pass through the upper cover and be assembled with the rear cover 4.

[0042] Optionally, multiple fixing holes 314 are provided, and the multiple fixing holes 314 are arranged around the outside of the first sealing ring 5. Increasing the number of fixing holes 314 can improve the connection stability between the upper cover and the lower housing, and at the same time enhance the sealing effect of the first sealing ring 5 and the second sealing ring 6.

[0043] Optionally, the high-voltage connector also includes a bushing 7, which is installed within the fixing hole 314. Fasteners pass through the bushing 7, and the upper cover and lower housing are connected by fasteners passing through the bushing 7. In specific implementations, since the socket housing 3 is an insulating plastic part, while the fasteners and bushing 7 are metal parts, the bushing 7 being assembled within the fixing hole 314 can reduce the destructive force on the socket housing 3 when the fasteners are tightened, thus extending the service life of the socket housing 3.

[0044] Optionally, the shielding shell 1 is a tubular structure. A hook 12 is provided at the first end of the tubular structure, and a spring piece 11 is provided at the second end. The shielding shell 1 is fitted onto the positioning part 32, with the hook 12 engaged at the connecting end and the spring piece 11 engaged at the end of the positioning part 32 opposite to the upper cover. In a specific implementation, the housing part 31 has a cavity, and the positioning part 32 is located within the cavity. The shielding shell 1 is inserted into the housing part 31 from the open end of the cavity and fitted onto the positioning part 32. The other end of the housing part 31 has a slit 313 communicating with the cavity, allowing the first end of the shielding shell 1 to be inserted into the slit 313, with the hook 12 extending out of the slit 313. The spring piece 11 is engaged at the end of the positioning part 32 opposite to the upper cover. Thus, both ends of the shielding shell 1 are connected to the lower housing, ensuring the installation stability of the shielding shell 1 and preventing it from detaching from the socket housing 3 during use. The upper cover is mounted on the lower housing, and the portion of the hook 12 extending out of the slit 313 is clamped between the connection end of the upper cover and the lower housing to ensure the installation stability of the shielding shell 1.

[0045] Optionally, barbs are provided on the terminal 2, and the barbs abut against the inner wall surface of the slot 321. The barbs are provided to enhance the friction between the terminal 2 and the inner wall surface of the slot 321, prevent the terminal 2 from moving within the slot 321, and further improve the connection stability between the terminal 2 and the socket housing 3. In this embodiment, the slot 321 is a stepped groove, and at the section with a smaller cross-section of the stepped groove, the portion of the terminal 2 with barbs abuts against the inner wall surface of the slot 321, while at the end with a larger cross-section of the stepped groove, there is a gap between the terminal 2 and the inner wall surface of the slot 321.

[0046] Optionally, terminal 2 includes an interlocked low-voltage terminal and two female terminals. Two female terminals and two interlocked low-voltage terminals are respectively provided. The two female terminals are arranged opposite each other along a first direction, and the two interlocked low-voltage terminals are arranged opposite each other along a second direction. The first direction and the second direction are perpendicular. In this embodiment, the first direction is... Figure 1 In the direction of ab, the second direction is Figure 1 In the cd direction. In specific implementation, the female terminal provides a stable electrical connection to ensure reliable transmission of high-voltage current, while the interlocked low-voltage terminal provides feedback through low-voltage signals to ensure that the status of the connector is monitored and controlled. The two work together to effectively prevent misoperation and failure, and improve the overall safety of the system.

[0047] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
