Description

Technical Field

[0001] This utility model relates to the field of electric vehicle electrical connections, and more specifically, to a novel fixed power terminal and assembly. Background Technology

[0002] With the increasing popularity of new energy vehicles, the demand for charging sockets for these vehicles is constantly increasing. Currently, most charging sockets on the market are assembled in the following order: first, the power terminals are installed into the housing, and the signal terminals and grounding terminals are pre-installed on the fixing parts to form accessories. Then, the fixing parts assembly with the terminals installed is installed into the socket housing. At this time, the fixing parts and the housing cooperate to limit the power terminals.

[0003] This installation method requires a fixed installation sequence, and the power terminals cannot be secured before the mounting components and housing are assembled. The existing sequential installation of power and signal terminals increases assembly steps and reduces assembly efficiency. It also easily leads to installation failures during the process. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a new type of fixed power terminal and assembly, which is expected to solve the problems of complex installation and easy failure of charging sockets.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] One aspect of this utility model provides a novel fixed power terminal, including a power terminal assembly;

[0007] The power terminal assembly is provided with a boss;

[0008] The boss extends out of the power terminal surface, and the size and position of the boss match the size and position of the fastener hook.

[0009] By providing bosses on the power terminal assembly and hooks on the fastener, the bosses can be engaged and secured, thus achieving assembly and fixation of the fastener and power terminals. The power terminals, along with other terminals, are pre-installed on the fastener as accessories, allowing for direct insertion into the housing, thereby simplifying the assembly process.

[0010] A further technical solution is that a fixing groove is provided on the boss;

[0011] The size and position of the fixing groove are matched with the size and position of the vertical rib on the fastener hook.

[0012] The fixing groove and hook can only limit the power terminal in the axial direction of the power terminal installation, making it less likely for the power terminal to fall out. However, the power terminal may still be displaced in the radial and circumferential directions. Therefore, by cooperating with the fixing groove of the boss and the vertical rib of the hook, the radial and circumferential limiting of the power terminal can be achieved.

[0013] A further technical solution is that the boss includes a first boss and a second boss;

[0014] The first boss and the second boss are located in two opposite directions where the power terminal contacts the fixing member.

[0015] While a single boss can achieve a limiting effect, using two bosses in opposite directions provides a better limiting effect and more stable installation.

[0016] Another aspect of this utility model provides an assembly, including the fixed power terminal and the fixing member as described above;

[0017] The fastener is provided with a power terminal mounting slot;

[0018] A hook is provided at the end of the mounting groove corresponding to the position of the boss;

[0019] The hook is provided with vertical ribs corresponding to the fixing groove of the boss.

[0020] The function of the fastener is to facilitate the installation of the power terminal, that is, to provide a locking hook at the corresponding position of the boss to achieve the limiting.

[0021] A further technical solution is that the end face of the hook is provided with a mating angle;

[0022] The specified tilt angle causes the distance between the hooks to gradually decrease along the mounting direction of the boss.

[0023] The angled design is primarily to address the issue of difficulty in engaging the latches when there are two bosses. The angled design causes the distance between the latches to gradually decrease along the boss installation direction. In other words, for boss installation, the latches form a funnel-like structure. This allows for direct downward pressure during boss installation, regardless of whether the boss's end face is sloped, to move the latches outwards and complete the boss installation. After installation, the latches return to their original position, achieving the desired positioning.

[0024] Compared with the prior art, this utility model has at least the following beneficial effects: By cooperating with the power terminal boss structure and the fastener hook structure, and by cooperating with the power terminal fixing groove structure and the fastener vertical rib, the displacement of the power terminal in all directions is restricted. Therefore, the power terminal can be pre-installed on the fastener, simplifying assembly and facilitating automation. Furthermore, by setting an inclination angle for the boss and a mating inclination angle for the hook, the problem of difficulty in engaging the boss with the hook when there are two bosses is effectively solved.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0035] A novel fixed power terminal, see Figure 1 Includes, power terminal assembly 1;

[0036] The power terminal assembly 1 is provided with a boss;

[0037] In this embodiment, the boss includes a first boss 11 and a second boss 13, which are disposed in two opposite directions where the power terminal contacts the fixing member 2.

[0038] It should be noted that the surfaces of the boss that act as limiting elements are the top and bottom surfaces, and the surface between the top and bottom surfaces is the end face. The end face of the boss comes into contact with the end face of the hook 21 during installation.

[0039] After installation, the top of the boss engages with the bottom of the hook 21 to achieve positioning.

[0040] The boss extends out of the power terminal surface, and the size and position of the boss match the size and position of the hook 21 of the fixing member 2.

[0041] The boss is provided with a fixing groove 12, see [link / reference] Figure 2 ;

[0042] The size and position of the fixing groove 12 are matched with the size and position of the vertical rib 22 on the hook 21 of the fixing member 2.

[0043] An assembly includes a fixed power terminal and a fixing member 2 as described above;

[0044] The fixing member 2 is provided with a power terminal mounting slot;

[0045] A hook 21 is provided at the end of the mounting groove corresponding to the position of the boss. See Figures 3-6 ;

[0046] The hook 21 is provided with a vertical rib 22 corresponding to the boss fixing groove 12.

[0047] The aforementioned engagement angle causes the distance between the hooks 21 to gradually decrease along the mounting direction of the boss.

[0048] During installation, the power terminal assembly 1 is moved into the fixed position along the power terminal mounting slot provided on the fixing member 2.

[0049] At this point, the power terminal can be tilted first, so that one of the protrusions of the power terminal is inserted into the hook 21. Then the tilted power terminal is straightened. Since the end face of the hook 21 is provided with a mating tilt angle, during the rotation process, the other protrusion passes through the other hook 21 to complete the installation.

[0050] Alternatively, the power terminal can be pressed down directly. Because the end face of the latch 21 has a mating angle, the latch 21 will deform, allowing the boss to pass through the latch 21, thus completing the installation. See [link / reference]. Figure 7 , Figure 8 .

[0051] Although the present invention has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and improvements can be made to the components and / or layout of the subject matter combination within the scope of the present application. Besides variations and improvements to the components and / or layout, other uses will be apparent to those skilled in the art.
