Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a terminal adapter structure. Background Technology

[0002] As new energy vehicles rapidly evolve towards high-voltage platforms and domain-centralized architectures, high-voltage connectors, as the core hubs of energy transmission, face increasingly stringent technical challenges. On the one hand, with increasingly compact in-vehicle electrical layouts, customers are placing higher demands on the spatial adaptability and wiring freedom of connectors, urgently requiring support for various complex-angle wiring solutions to meet diverse installation scenarios. On the other hand, under the trend of mass production, assembly efficiency and process reliability have become key bottlenecks restricting capacity expansion. Traditional multi-level adapters and manual, intensive assembly methods are unable to meet the stringent requirements of OEMs for cycle time and consistency.

[0003] Currently, domain controller connectors commonly employ screw-type terminal adapters. For example, patent CN222839079U discloses a 90° right-angle metal connector that uses a stamped U-shaped power copper busbar to achieve right-angle cable exit and a snap-fit ​​assembly structure to improve local assembly efficiency. However, in large-scale application scenarios, this type of solution still faces the following technical problems: high assembly process complexity: core electrical connections rely on multi-stage screw-in operations, requiring repeated positioning and torque control, thus extending the overall assembly time. Utility Model Content

[0004] This invention proposes a terminal adapter structure, which solves the problem of high assembly process complexity in the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A terminal adapter structure includes an adapter housing and terminals. Bolts are mounted on the terminals, which are connected to the adapter housing. The adapter housing and terminals cooperate to axially limit the movement of the bolts. Integrating the bolts onto the adapter housing creates a single, integrated structure, effectively reducing the number of parts. When the adapter structure is used for mating connections, it can be directly connected to a mating connector, reducing the assembly process of bolts and terminals. Furthermore, the bolt mounting holes can be located within the sealing area, eliminating the need for separate sealing components. This simplifies the assembly process, saves connector parts, and improves installation efficiency during use.

[0007] The adapter housing has terminal mounting holes inside, and the terminals pass through these holes. The inner wall of the terminal mounting holes has elastic retaining plates, and the terminals have terminal hanging plates that engage with each other. After the terminal is inserted into the adapter housing, the engagement of the elastic retaining plates and terminal hanging plates axially limits the terminal, preventing it from detaching from the head of the adapter housing.

[0008] Ribs are provided on the inner wall of the terminal mounting hole, and the ribs are arranged along the axial direction of the terminal mounting hole. The ribs radially limit the terminal, ensuring that the terminal is stably installed in the terminal mounting hole, thereby improving the structural stability of the terminal after installation on the adapter housing.

[0009] The terminal has a terminal bending portion at its end, which mates with the end face of the adapter housing. The terminal bending portion axially limits the terminal, preventing it from detaching from the tail of the adapter housing.

[0010] The terminal bend is provided with a bolt mounting hole, and the bolt passes through the bolt mounting hole. The bolt passes through the bolt mounting hole and connects with the mating terminal, so that the two terminals are in close contact and the connector is electrically connected.

[0011] The adapter housing has bolt tightening holes arranged side-by-side with the terminal mounting holes. After the terminal is connected to the adapter housing, the bolt tightening holes correspond to the bolt mounting holes on the terminal. When mating the connectors, a wrench is inserted into the bolt tightening holes to tighten the bolts.

[0012] A retaining ring is provided inside the bolt tightening hole. The bolt is a hexagon socket head cap screw, and the inner diameter of the retaining ring is smaller than the diameter of the bolt head. The retaining ring limits the bolt, preventing it from coming out of the bolt tightening hole and ensuring stable installation of the bolt within the adapter housing.

[0013] The distance between the retaining ring and the end of the adapter housing is less than the length of the bolt. This prevents the bolt from separating from the terminal after it is connected to the adapter housing, improves the ease of connection between the bolt and the terminal during connector mating, and increases assembly efficiency.

[0014] The adapter housing is equipped with a plug, which corresponds to the port position of the bolt tightening hole. After the bolt is tightened, the plug seals the bolt tightening hole to prevent debris from falling into it.

[0015] The beneficial effects of this utility model are: by integrating the terminals and bolts onto the adapter housing, the bolts, terminals, and adapter housing form an integral structure. When the adapter structure is used for mating connection, the entire adapter structure can be directly connected to the mating connector, reducing the assembly process of bolts and terminals, effectively reducing the number of parts in the connector mating, effectively simplifying the assembly process, and improving the installation efficiency of the adapter structure.

[0023] 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.

[0024] Example 1, such as Figure 1As shown, a terminal adapter structure includes an adapter housing 1 and a terminal 3. The terminal 3 is provided with a bolt 2. The terminal 3 is connected to the adapter housing 1. The adapter housing 1 and the terminal 3 cooperate to axially limit the bolt 2. The connection method between terminal 3 and adapter shell 1 is any one of mounting platform limiting, hard interference link, or integral injection molding. Terminal 3 is a long strip plate or a circular structure. In this embodiment, terminal 3 is snapped into adapter shell 1, and terminal 3 is a long strip plate. Specifically, adapter shell 1 is made of plastic material by injection molding, and terminal 3 is made of copper alloy by stamping. After terminal 3 is connected to adapter shell 1, it can form an independently transportable pre-assembled module. Bolt 2 is confined inside adapter shell 1, and the head of bolt 2 is wrapped inside adapter shell 1. Integrating terminal 3 and bolt 2 onto adapter shell 1 makes bolt 2, terminal 3, and adapter shell 1 form an integral structure. When the adapter structure is plugged in, the entire adapter structure can be directly connected to the plug-in connector, reducing the assembly process of bolt 2 and terminal 3, avoiding the risk of bolt loss during on-site assembly, effectively reducing the number of parts for connector plugging, effectively simplifying the assembly process, and improving the installation efficiency of the adapter structure.

[0025] Furthermore, such as Figure 2 As shown, the adapter housing 1 has a terminal mounting hole 11 inside, and the terminal 3 passes through the terminal mounting hole 11. An elastic retaining plate 13 is provided on the inner wall of the terminal mounting hole 11, and a terminal hanging plate 33 is provided on the terminal 3. The elastic retaining plate 13 and the terminal hanging plate 33 are engaged. When the terminal 3 is inserted into the terminal mounting hole 11, the terminal 3 presses against the elastic retaining plate 13, causing the elastic retaining plate 13 to undergo elastic deformation. After the terminal 3 is installed in place, the terminal hanging plate 33 on the terminal 3 corresponds to the position of the elastic retaining plate 13. The elastic retaining plate 13 springs back to its original position under its own elasticity. At this time, the elastic retaining plate 13 and the terminal hanging plate 33 are connected. The engagement of the elastic retaining plate 13 and the terminal hanging plate 33 forms a mechanical lock and axially limits the terminal 3, preventing the terminal 3 from coming out of the head of the adapter housing 1.

[0026] In addition, a guide slope is provided on the lower side of the elastic card table 13, which facilitates the terminal 3 to squeeze the elastic card table 13 during the installation of the terminal 3, so that the elastic card table 13 will undergo elastic deformation.

[0027] Furthermore, such as Figure 2 As shown, a rib 12 is provided on the inner wall of the terminal mounting hole 11, and the rib 12 is arranged along the axial direction of the terminal mounting hole 11. The rib 12 radially limits the terminal 3, ensuring that the terminal 3 is stably installed in the terminal mounting hole 11, thereby improving the structural stability of the terminal 3 after installation on the adapter housing 1.

[0028] Furthermore, such as Figure 3As shown, the end of terminal 3 is provided with a terminal bending portion 31, which mates with the end face of the adapter housing 1. The terminal bending portion 31 is a 90-degree right-angle bend. After terminal 3 is installed on the adapter housing 1, the terminal bending portion 31 axially limits terminal 3 to prevent terminal 3 from coming off the tail of the adapter housing 1.

[0029] Furthermore, the terminal bend 31 is provided with a bolt mounting hole 32, and the bolt 2 passes through the bolt mounting hole 32. The bolt 2 passes through the bolt mounting hole 32 and connects with the mating terminal, so that the two terminals are in close contact and realize the electrical connection of the connector.

[0030] Example 2, based on Example 1, provides a terminal adapter structure, such as... Figure 2 As shown, the adapter housing 1 has bolt tightening holes 15 inside, which are arranged side by side with the terminal mounting holes 11. After the terminal 3 is connected to the adapter housing 1, the bolt tightening holes 15 correspond to the bolt mounting holes 32 on the terminal 3. When mating the connectors, a wrench is inserted into the bolt tightening holes 15 to rotate the bolt 2, so that the bolt 2 connects with the nut inside the mating connector, thereby achieving the mating of the adapter connectors.

[0031] Furthermore, a retaining ring 14 is provided inside the bolt tightening hole 15. The bolt 2 is an internal hexagonal bolt, and the inner diameter of the retaining ring 14 is smaller than the diameter of the head of the internal hexagonal bolt. The retaining ring 14 is integrally injection molded with the adapter housing 1; the retaining ring 14 axially limits the bolt 2, restricting the axial movement of the bolt 2 within the bolt mounting hole 15, preventing the bolt 2 from coming out of the bolt tightening hole 15, and ensuring the integrity of the adapter structure.

[0032] Furthermore, the distance between the retaining ring 14 and the end of the adapter housing 1 is less than the length of the bolt 2. After the terminal 3 is connected to the adapter housing 1, this prevents the bolt 2 from separating from the terminal 3, and improves the ease of connection between the bolt 2 and the terminal 3 during connector mating, thereby increasing assembly efficiency.

[0033] Furthermore, the adapter housing 1 is equipped with a plug, which corresponds to the port position of the bolt tightening hole 15. After the bolt 2 is tightened, the plug seals the bolt tightening hole 15 to prevent debris from falling into the bolt tightening hole 15.

[0034] like Figure 4 , Figure 5 As shown, the connection process between the adapter structure and the mating connector is as follows: First, the integral adapter structure consisting of the adapter shell 1, bolt 2 and terminal 3 is directly mated with the mating connector, so that the bent part 31 of the terminal contacts the mating terminal 4. Then, a wrench is used to insert into the bolt tightening hole 15 and rotate the bolt 2 so that the bolt 2 passes through the terminal 3 and the mating terminal 4 and is connected with the nut. After the bolt 2 is tightened, the connection between the adapter structure and the mating connector is completed.

[0035] Example 3 differs from Example 1 in that the terminal 3 is a circular terminal structure, and the terminal 3 is connected to the adapter shell 1 by integral injection molding, ensuring that the terminal 3 is stably installed in the adapter shell 1.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
