Description

Technical Field

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

[0002] High-voltage connectors are electrical connection devices specifically designed for transmitting high voltage and high current. They are widely used in electric vehicles, new energy storage systems, and industrial high-voltage equipment, and are core components for achieving rapid connection and disconnection in high-voltage circuits. Their design must meet stringent requirements such as high-voltage insulation, high-current transmission, and safety protection, making them a key component for ensuring the stable operation of high-voltage systems.

[0003] In traditional male connector assembly designs, terminal position retainers serve to lock the male terminals in place and enhance their retention force within the connector, preventing them from dislodging under external force and causing power outages. Existing high-voltage connectors have limited internal space, and to ensure safe operation, they require electrical isolation. Therefore, the proper placement of the terminal position retainers is crucial, and how to rationally position them is a pressing issue that needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-stability high-voltage connector socket and a high-voltage connector.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A high-stability high-voltage connector socket includes a socket housing, male terminals, and a terminal retainer. The socket housing includes a flange, a connecting housing disposed on the outer end face of the flange, and two receiving grooves built into the connecting housing and passing through the flange. The two male terminals are respectively inserted into one of the receiving grooves. The receiving grooves are covered with a shielding layer. The inner end of the male terminal extends out from the inner end of the receiving groove, and the inner ends of the two receiving grooves and the inner ends of the two male terminals together form a slot. The terminal retainer is adapted to the slot and is slidably inserted into the slot in a radial direction to lock the two male terminals in a direction perpendicular to the extension direction of the male terminals.

[0007] Preferably, the terminal retainer includes a first piece and a second piece, the second piece being vertically fixed to the upper surface of the first piece, a first slot adapted to the first piece being formed between the inner ends of the two receiving grooves, and a second slot adapted to the second piece being formed between the inner ends of the two male terminals.

[0008] Preferably, the first slot has limiting grooves on both side walls, and the first piece has limiting blocks on both sides that match the limiting grooves. The limiting blocks engage with the limiting grooves to confine the terminal retainer within the slot.

[0009] Preferably, the rear side of the limiting block abuts against the contact surface of the limiting groove, and the rear side and the contact surface are beveled surfaces with the same slope.

[0010] Preferably, the proximal side of the receiving groove has an opening, and the two openings are connected to the first slot to form a T-shape. A limiting rod is fixed to the proximal side of the first piece. When the terminal retainer is confined in the slot, the inner surface of the limiting rod closes the two openings and abuts against the male terminal.

[0011] Preferably, the front side of the limiting block is a beveled surface, and the T-shaped corner of the first slot has a beveled surface with the same slope as the front side.

[0012] Preferably, a limiting plate with a width greater than its thickness is fixed to the proximal side of the second piece, and the two form a T-shape. When the second piece is inserted into the second slot, the inner surface of the limiting plate abuts against the proximal sides of the two male terminals.

[0013] Preferably, a signal terminal is also provided inside the flange, and a groove is formed on the distal side of the second piece. A core wire is connected to the inner end of the signal terminal, and the core wire passes through the groove.

[0014] Preferably, a sealing ring is also embedded in the inner end face of the flange.

[0015] High-voltage connectors, including the high-stability high-voltage connector socket and the compatible plug as described above.

[0016] The beneficial effects of this utility model are mainly reflected in:

[0017] 1. This solution uses the gap formed between the inner end of the receiving groove and the inner end of the male terminal as a slot for inserting the terminal retainer, so as to maximize the use of the space inside the connector socket. This allows the terminal retainer to be inserted into the male terminal from the radial direction, thereby forming a secondary locking of the male terminal from the radial direction and limiting the radial position of the male terminal. Furthermore, the terminal retainer slides into the slot in a straight line, which can improve the smoothness and convenience of its insertion.

[0018] 2. The second piece of the terminal retainer can prevent the male terminal from becoming loose while ensuring that there is always a gap between the two male terminals to meet the safety requirements of electrical clearance isolation and ensure electrical safety. Attached Figure Description

However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0029] like Figures 1 to 7As shown, this utility model discloses a high-stability high-voltage connector socket, including a socket housing, male terminals 2, and terminal retainers 3. The socket housing includes a flange 101, a connecting housing 103 disposed on the outer end face of the flange 101, and two receiving grooves 102 built into the connecting housing 103 and passing through the flange 101. The two male terminals 2 are respectively inserted into one of the receiving grooves 102. The receiving grooves 102 are covered with a shielding layer 6 to provide shielding. The inner end of the male terminal 2 extends out from the inner end of the receiving groove 102, and the inner ends of the two receiving grooves 102 and the inner ends of the two male terminals 2 together form a slot. The terminal retainer 3 is adapted to the slot and is slidably inserted into the slot in a radial direction to lock the two male terminals 2 in a direction perpendicular to the extension direction of the male terminals 2.

[0030] This solution utilizes the gap between the inner end of the receiving groove 102 and the inner end of the male terminal 2 as a slot for inserting the terminal retainer 3, maximizing the use of space within the connector socket. This allows the terminal retainer 3 to be inserted into the male terminal 2 radially, locking it radially and limiting its radial position. Furthermore, the terminal retainer 3 slides linearly into the slot, improving the smoothness and ease of insertion. The receiving groove 102 penetrates the flange 101 to fit the male terminal 2. A limiting frame 1021, matching the outer end of the male terminal 2, is also provided within the receiving groove 102 to enclose the outer periphery of the male terminal 2, providing a safety feature against finger contact. Other existing technologies are not the focus of this solution and will not be elaborated upon here.

[0031] Specific examples Figure 3 As shown, the terminal retainer 3 includes a first piece 301 and a second piece 302. The second piece 302 is vertically fixed to the upper surface of the first piece 301. A first slot 401 adapted to the first piece 301 is formed between the inner ends of the two receiving grooves 102, and a second slot 402 adapted to the second piece 302 is formed between the inner ends of the two male terminals 2. Preferably, the first piece 301 and the second piece 302 are integral components and are symmetrical to ensure effective locking with both male terminals 2.

[0032] Furthermore, limiting grooves 403 are provided on both side walls of the first slot 401, and limiting blocks 303 matching the limiting grooves 403 are provided on both sides of the first piece 301. The limiting blocks 303 engage with the limiting grooves 403 to confine the terminal retainer 3 within the slot.

[0033] like Figures 2-4 As shown, when the limiting block 303 engages with the limiting groove 403, the rear side 3031 of the limiting block 303 abuts against the contact surface 4021 of the limiting groove 403, and the rear side 3031 and the contact surface 4021 are oblique cut surfaces with the same slope, so that the limiting block 303 can slide into or out of the limiting groove 403 more conveniently.

[0034] The accommodating groove 102 has an opening 1021 on its proximal side. The two openings 1021 are connected to the first slot 401 to form a T-shape. A limiting rod 304 is fixed to the proximal side of the first piece 301. When the terminal retainer 3 is confined in the slot, the inner surface of the limiting rod 304 closes the two openings 1021 and abuts against the male terminal 2, so that the terminal retainer 3 effectively locks the male terminal 2.

[0035] Furthermore, the front side 3032 of the limiting block 303 is beveled, and the T-shaped corner 4011 of the first slot 401 has a bevel with the same slope as the front side 3032. This structural arrangement allows the first piece 301 to slide more smoothly into the first slot 401, reducing unnecessary wear at the T-shaped corner 4011 when the terminal retainer 3 is inserted.

[0036] A limiting plate 305, wider than its thickness, is fixed to the proximal side of the second piece 302, forming a T-shape. When the second piece 302 is inserted into the second slot 402, the inner surface of the limiting plate 305 abuts against the proximal sides of the two male terminals 2. The limiting plate 305 limits the movement limit of the terminal holder 3, preventing damage caused by over-insertion. Furthermore, the limiting plate 305 increases the contact area between the second piece 302 and the male terminals 2, making the connection between the second piece 302 and the two male terminals 2 more stable and reliable.

[0037] A signal terminal 5 is also provided inside the flange 101. A groove 306 is formed by the recessed side of the second piece 302. A core wire is connected to the inner end of the signal terminal 5 and passes through the groove 306. The groove 306 protects the core wire and limits its extension in the same direction as the signal terminal 5, preventing the core wire from being excessively skewed within the connector socket or tangled with other structures, thus ensuring an effective connection between the core wire and the signal terminal 5.

[0038] In addition, a sealing ring 104 is embedded in the inner end face of the flange 101 to seal the connection between the inner end face of the flange 101 and other components. A protective cover can also be provided on the outside of the flange 101 to protect the outer end face of the flange 101 from the influence of the external environment.

[0039] This utility model also discloses a high-voltage connector, including a high-stability high-voltage connector socket as described above and a compatible plug. The high-voltage connector also includes other necessary components, such as a female terminal that plugs into the male terminal 2; these are existing structures and not the focus of this solution, so they will not be described in detail here.

[0040] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0041] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
