Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric appliance connecting piece especially relates to a terminal connecting assembly with limiting function. BACKGROUND

[0002] The copper bar is a common conductive connecting piece in the circuit, and the mounting position for connecting the terminal is arranged on the copper bar. The existing terminal and copper bar are usually connected by bolts. The screw is first passed through the copper bar and the terminal, and then the nut is screwed on. The nut is tightened, and the copper bar and the terminal are clamped by the large end of the screw.

[0003] After the above-mentioned terminal and copper bar are connected, since the nut can only exert axial pressing force on the terminal, there is no any limitation in the circumferential rotation direction of the terminal, which leads to that the operator pulling the lead wire will cause the connected terminal to rotate around the screw, and deflection occurs. Moreover, during the installation process, since the screw lacks limiting, the screw rotation must be limited on one side of the copper bar by using a tool during the installation of the nut, and the nut is tightened by using a tool on the other side, which leads to that the process of installing the terminal is inconvenient. Therefore, the existing connection structure of the terminal and the copper bar has the defects of inconvenient installation and easy deflection after connection. SUMMARY

[0004] In view of the defects of the existing connection structure of the terminal and the copper bar, such as inconvenient installation and easy deflection after connection, the utility model aims to provide a connection structure for connecting the terminal and the copper bar and capable of limiting the rotation of the terminal and the screw relative to the copper bar.

[0005] In order to solve the above-mentioned technical problem, the utility model solves the problem by the following technical scheme:

[0006] A terminal connecting assembly with limiting function, comprising a bottom plate, a threaded stud fixed with the bottom plate and connected with a nut after passing through the copper bar and the mounting end of the terminal, and a pair of limiting columns fixed with the bottom plate and limiting the rotation of the wiring end of the terminal to both sides of the threaded stud after passing through the copper bar, wherein the wiring end of the terminal is located between the two limiting columns.

[0007] By adopting the above-mentioned scheme, the limiting column and the threaded stud of the terminal connecting assembly in the utility model are fixed on the bottom plate. When the threaded stud and the limiting column are connected with the copper bar, both of them need to pass through the copper bar. When the threaded stud is subjected to circumferential force, the limiting column can limit the rotation of the threaded stud. Therefore, when the nut is tightened, the threaded stud does not need to be fixed by using an additional tool. After the limiting column in the utility model passes through the copper bar, the wiring end of the terminal is located between the two limiting columns. When the terminal is subjected to circumferential force and rotates, the wiring end will abut against the limiting column and cannot rotate further. Therefore, the limiting column in the utility model can ensure that the terminal connecting assembly does not deflect when connected with the copper bar, and can prevent the wiring end of the terminal from turning over on both sides after installation, so that the copper bar and the terminal are more convenient to connect, and the stability after connection is better.

[0008] As preferred, the connecting assembly further comprises a limiting member for limiting the deflection of the terminal between the two limiting posts.

[0009] With the above scheme, the connection between the limiting post and the bottom plate is usually integrally formed, which saves the manufacturing cost the most. However, various types and sizes of terminals are used in actual production, and the spacing between the limiting posts cannot be adapted to each type of terminal. If the width of the terminal is small and the spacing between the limiting posts is large, there will still be a certain degree of deflection. Although the terminal will not interfere with other terminals after a large deflection, it will also cause the terminals on the copper bar to be arranged irregularly. If a connecting assembly with a spacing of the limiting post that can exactly adapt to the terminal of each type of terminal is configured for each type of terminal, the cost of opening the mold will be greatly increased. Therefore, the present scheme wants to adapt to different types of terminals by setting limiting members matched with various types of terminals.

[0010] As preferred, the limiting member comprises a limiting sleeve that is respectively sleeved on the two limiting posts and whose outer wall abuts against the terminal.

[0011] As preferred, the limiting sleeve is made of a flexible material and is in interference fit with the limiting post.

[0012] With the above scheme, the limiting sleeve can be a rubber sleeve. Only the limiting sleeve with a wall thickness that adapts to different types of terminals needs to be provided. The terminal is abutted on both sides of the limiting sleeve, and almost no small deflection occurs.

[0013] As preferred, the limiting member comprises an elastic member that is arranged to be elastically stretched transversely relative to the terminal on the limiting post.

[0014] With the above scheme, when the terminal is placed between the limiting posts, the elastic member will be pushed to both sides. When the terminal is completely installed, the end of the elastic member will be elastically abutted against the side wall of the terminal, limiting the small deflection of the terminal.

[0015] As preferred, the elastic member comprises a wave bead screw, and the limiting post is provided with a threaded hole for screwing the wave bead screw.

[0016] With the above scheme, the wave bead screw is characterized in that the extension length of the wave bead screw relative to the limiting post can be controlled by screwing in or out. Therefore, the operator can adjust the extension length of the wave bead screw to adapt to different types of terminals.

[0017] As preferred, one set of elastic members is respectively arranged on the two limiting posts.

[0018] With the above scheme, the elastic members are symmetrically arranged. When they are popped out and abut against the terminal, the terminal can be kept at the center between the two limiting posts, looking more orderly.

[0019] This utility model, by adopting the above technical solutions, has significant technical effects: In this solution, the limiting post and stud on the terminal connection assembly are fixed together on the base plate. When the stud and the limiting post are connected to the copper busbar, they need to pass through the copper busbar. When the stud is subjected to circumferential force, the limiting post can restrict the rotation of the stud. Therefore, when tightening the nut, no additional tools are needed to fix the stud. After the limiting post passes through the copper busbar, the terminal's wiring end is located between the two limiting posts. When the terminal is subjected to circumferential force and rotates, the wiring end will abut against the limiting post and cannot rotate further. Therefore, the limiting post in this solution can ensure that the terminal connection assembly does not deflect when connected to the copper busbar. After installation, it can prevent the wiring end of the terminal from flipping on both sides, making it easier to connect the copper busbar and the terminal, and improving the stability after connection.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] A terminal connection assembly with a limiting function, according toFigure 1 , 2 As shown, the device includes a base plate with a stud fixedly protruding thereon. The stud passes through the copper busbar and the mounting end on the terminal and is connected to a nut. A pair of limit posts are fixedly protruding on the base plate. After the limit posts pass through the copper busbar, the wiring terminal on the terminal is located between the two limit posts. The limit posts can restrict the wiring terminal from rotating around the stud to both sides.

[0031] Based on the above structure, refer to Figure 1 , 2 As can be seen, in this embodiment, the limiting post and stud on the terminal connection assembly with limiting function are fixed together on the base plate. When the stud and the limiting post are connected to the copper busbar, they need to pass through the copper busbar. When the stud is subjected to circumferential force, the limiting post can limit the rotation of the stud. Therefore, when tightening the nut, no additional tool is needed to fix the stud. After the limiting post passes through the copper busbar in this solution, the terminal terminal is located between the two limiting posts. When the terminal is subjected to circumferential force and rotates, the terminal terminal will abut against the limiting post and cannot rotate further. Therefore, the limiting post in this solution can ensure that the terminal connection assembly does not deflect when connected to the copper busbar. After installation, it can prevent the terminal terminal from flipping on both sides, making it easier to connect the copper busbar and the terminal and improving the stability after connection.

[0032] Example 2

[0033] Based on Embodiment 1, this embodiment further defines a terminal connection assembly with a limiting function. The connection assembly also includes a limiting member that restricts the deflection of the terminal between two limiting posts. Figure 3 As shown, the limiting component includes limiting sleeves respectively fitted on the two limiting posts. The outer walls of the limiting sleeves abut against the wiring terminals. In this embodiment, the limiting sleeves are made of rubber, and the inner walls of the limiting sleeves are interference-fitted with the outer walls of the limiting posts.

[0034] Based on the above structure, refer to Figure 3 It is known that various types of terminals are used in actual production. Configuring a connection component with a spacing of limiting posts that perfectly matches the width of the terminal wiring for each type of terminal would greatly increase the cost of mold making. In this embodiment, it is only necessary to equip a limiting sleeve with a wall thickness that matches the different types of terminals. Both sides of the terminal abut against the limiting sleeve, and there will be almost no slight deflection.

[0035] Example 3

[0036] Based on Embodiment 1, this embodiment further defines a terminal connection assembly with a limiting function. The connection assembly also includes a limiting member that restricts the deflection of the terminal between two limiting posts. The limiting member includes an elastic member on the limiting posts that is laterally elastically telescoping relative to the terminal. Figure 4 , 7As shown, in the embodiment, the elastic members are two wave bead screws, and are arranged on the two limiting columns respectively.

[0037] In combination with the above structure, it can be known from the description of the above embodiment that Figures 4 to 7 It can be known that the wave bead screw is characterized in that the extension length of the wave bead screw relative to the limiting column can be controlled by screwing in or out, when the terminal is put between the limiting columns, the steel ball at the top of the wave bead screw is first pushed to the two sides to make it shrink into the screw, and the spring inside the screw is compressed, the spring drives the steel ball to abut against the two side walls of the terminal to limit the small turning of the terminal to the two sides, and the elastic members in the embodiment are arranged on the two sides of the limiting column, and the operator can keep the wiring terminal at the center between the two limiting columns by adjusting.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing embodiments, or equivalent replacement for part of the technical features.
