[0002] A wiring terminal is a fitting product used to achieve electrical connection and is classified as a connector in the industry. It is a metal sheet enclosed in insulating plastic with holes at both ends for inserting wires and screws for tightening or loosening. For example, when two wires need to be connected or disconnected sometimes, terminals can be used to connect them and can be disconnected at any time without welding or winding them together, which is very convenient and fast. Moreover, it is suitable for interconnecting a large number of wires. In the power industry, there are special terminal blocks and terminal boxes, all of which are wiring terminals, single-layer, double-layer, current-carrying, voltage-measuring, ordinary, breakable, etc. A certain crimping area is to ensure reliable contact and to ensure that enough current can pass through. With the increasing level of industrial automation and the increasing strictness and precision of industrial control requirements, the usage and application range of wiring terminals are increasing, and the types are also increasing. Besides PCB board terminals, the most widely used ones also include hardware terminals, nut terminals, spring terminals, etc.

[0003] When the existing wiring terminal is connected to a wire, the metal sheet is generally adjusted directly through screws to clamp and fix the wire.

[0004] However, when the wire is bent, due to the lack of guiding and limiting between the wire and the wiring terminal, it is easy to occur the problem of bending and short-circuiting at the connection, further reducing the practicability of the anti-bending connection structure.

[0005] Therefore, we propose an anti-bending connection structure for a wiring terminal. Content of the Utility Model

[0008] Further, the conical ferrule is composed of a plurality of plastic elastic sheets, and the plurality of plastic elastic sheets are arranged in an equidistant circular array along the inner diameter of the wire opening and the ends are fixed inside the wire opening.

[0009] Further, a connecting bolt penetrates through the inside of the connecting plate, and a threaded hole for connecting the connecting bolt is formed on the surface of the protection plate.

[0010] Further, guide blocks are fixedly connected to both sides of the connecting plate, and guide grooves for penetrating the guide blocks are formed on the surface of the protection plate.

[0011] Further, the protection plate is rectangular in shape, and the rectangular size is larger than the position of the front side of the wiring part of the terminal body.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: an anti-bending connection structure for a wiring terminal, including a wiring terminal body 1, a protection plate 2 is installed on the front surface of the wiring terminal body 1, a plurality of wiring ports 3 are opened on the surface of the protection plate 2, and the plurality of wiring ports 3 are aligned with the wiring part of the wiring terminal body 1. An anti-bending mechanism 4 is arranged on the front surface of the protection plate 2; wherein the anti-bending mechanism 4 includes a connecting plate 41 arranged on the front surface of the protection plate 2, a wire port 42 is opened on the front surface of the connecting plate 41, a conical bushing 43 is installed inside the wire port 42, and the outer diameter of the conical bushing 43 is adapted to the inside of the wiring port 3. Under the setting of the protection plate 2, it can be installed on the front surface of the wiring terminal body 1 to play a protective role.

[0022] According to Figure 3 , it can be known that the conical bushing 43 is composed of several plastic elastic sheets. The several plastic elastic sheets are arranged in an equidistant circular array along the inner diameter of the wire port 42 and the ends are fixed inside the wire port 42. Under the condition that the conical bushing 43 is composed of several plastic elastic sheets, it can automatically expand when the wire passes through the inside of the conical bushing 43 and can be adjusted according to the sizes of different wires, so as to support and limit the surface of the wire, thereby improving the secondary limit of the wiring part of the wire and the wiring terminal body 1 and reducing the bending problem that is likely to occur.

[0023] According to Figure 2 , it can be known that a connecting bolt 44 is connected through the inside of the connecting plate 41, and a threaded hole 45 for connecting the connecting bolt 44 is opened on the surface of the protection plate 2. By rotating the connecting bolt 44, it can be connected inside the threaded hole 45, so as to adjust the distance between the connecting plates 41 and better install and limit the wire.

[0024] According to Figure 2 , it can be known that guide blocks 46 are fixedly connected to both sides of the connecting plate 41, and guide grooves 47 for passing through the guide blocks 46 are opened on the surface of the protection plate 2. Under the setting of the guide blocks 46, the guide blocks 46 can be inserted into the guide grooves 47, so as to play a guiding and limiting role when the connecting plate 41 is adjusted.

[0025] According to Figure 2It can be seen that the protective plate 2 is rectangular in shape, and the rectangular size is larger than the position of the front side of the wiring part of the terminal body 1. With the rectangular setting of the protective plate 2, it can be better used to install and enclose the front side of the terminal body 1, thereby protecting the wiring part of the terminal body 1.

[0026] According to Figure 2 It can be seen that there are multiple wire ports 42 and tapered ferrules 43. The multiple wire ports 42 and tapered ferrules 43 are aligned with the center of the wiring port 3. With the multiple sets of wire ports 42 and tapered ferrules 43, it can simultaneously install and protect the interiors of multiple wiring ports 3.

[0027] The working principle of the present utility model: When in use, first, the protective plate 2 is installed on the front side of the terminal body 1 and aligned with the wiring part through the protective plate 2. Then, the anti-bending mechanism 4 is installed on the surface of the protective plate 2. When the terminal body 1 is not working, the connecting plate 41 can be closely attached to the front side of the protective plate 2, so that the tapered ferrule 43 inside the wire port 42 is inserted into the wiring port 3, thereby closing the interior of the wiring port 3 and reducing the oxidation of the metal sheet inside the terminal body 1 caused by external water vapor.

[0028] When the terminal body 1 is working, the connecting plate 41 is moved away from the front side of the protective plate 2, so that the wire can pass through the wire port 42 and the wiring port 3 to the inside of the terminal body 1 to complete the wiring work. Through the setting of the tapered ferrule 43, it can limit and support the surface of the wire, and can reduce the problem that the wire is easily bent and damaged.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features.
