Description

Technical Field

[0001] This disclosure relates to the technical field of computer monitoring systems for hydropower stations, and in particular to a splicing terminal block. Background Technology

[0002] A hydropower station computer monitoring system is a system that uses digital electronic computers to monitor and manage the power generation process of a hydropower station. Its core function is to realize the automated control and operation optimization of the hydropower station. When connecting existing hydropower station computer monitoring systems, terminal blocks are usually used to connect different equipment lines. A terminal block is a device used for connecting wires or cables in an electrical system. It can centrally manage multiple wires or cables and realize functions such as electrical connection, signal distribution and circuit protection.

[0003] In the process of implementing the embodiments of this disclosure, the inventors discovered the following problems with the prior art: Most of the terminals of the existing terminal blocks are fixedly connected to each other. In actual use, when one terminal is damaged, the user needs to disassemble the entire terminal block for replacement and rewire it. The overall operation process is relatively complicated and the practicality is poor. Summary of the Invention

[0004] In view of this, the present disclosure provides a splicing terminal block, which at least partially solves the problem in the prior art of replacing the entire terminal block when a single terminal is damaged.

[0005] This disclosure provides a plurality of detachably arranged terminal blocks, each terminal block including a mounting mechanism and a cover mechanism capable of engaging with the top of the mounting mechanism. The mounting mechanism contains a main body mechanism, which includes a clamping part for fixing wires and a connecting part connected to the clamping part. The connecting part extends from the interior to the exterior of the mounting mechanism.

[0006] Optionally, the mounting mechanism includes a lower protective shell, on one side of which a slider extending along its length is provided, and on the other side a sliding groove is provided, and two adjacent terminals are connected by the cooperation of the slider and the sliding groove.

[0007] Optionally, it also includes a mounting rail, wherein the bottom of the lower protective shell is provided with a mounting groove extending along its width direction, and the mounting groove slides into the mounting rail.

[0008] Optionally, the main body mechanism includes a wiring frame, a lower clamping plate disposed inside the wiring frame, an upper clamping plate disposed on the lower clamping plate, and a fastener slidably disposed on the top of the wiring frame. The beginnings of the upper clamping plate and the lower clamping plate are U-shaped to form the clamping part, and the end of the lower clamping plate is the connecting part.

[0009] Optionally, the fastener is a fastening bolt, which is screwed onto the wiring frame, and the bottom of the fastening bolt abuts against the upper clamping plate.

[0010] Optionally, the upper cover mechanism includes an upper protective shell, the head of which is provided with an upper protective rubber ring, and the head of the lower protective shell is provided with a lower protective rubber ring. When the upper protective shell is fastened to the lower protective shell, the upper protective rubber ring and the lower protective rubber ring are engaged.

[0011] Optionally, the tail of the upper protective shell is hinged to the tail of the lower protective shell.

[0012] Optionally, the upper protective shell has an insertion block at the bottom of its head, and the lower protective shell has a slot at the top of its head that can cooperate with the insertion block.

[0013] Optionally, the upper cover mechanism may further include a protective film disposed at the bottom of the cover plate, wherein flame retardant powder is disposed inside the protective film.

[0014] Optionally, the protective film can be made of hot melt adhesive film material.

[0015] The modular terminal block provided in this disclosure integrates multiple terminals in a detachable manner, allowing users to flexibly assemble them according to actual needs to form terminal blocks of different lengths and functions. When one of the terminals is damaged, only that terminal needs to be removed and replaced with a new one, without having to replace the entire terminal block. This avoids the need to replace the entire terminal block when it is damaged, which is a common problem with traditional terminal blocks. The modular design and flexible combination significantly improve the practicality and ease of maintenance of the terminal block.

[0016] The above description is merely an overview of the technical solution disclosed herein. In order to better understand the technical means of this disclosure and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this disclosure more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

Detailed Implementation

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0026] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0028] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0029] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0030] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0031] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0032] This disclosure provides a splicing terminal block, including a plurality of detachably arranged terminals. Each terminal block includes a mounting mechanism 2 and a cover mechanism 1 that can be engaged with the top of the mounting mechanism 2. The mounting mechanism 2 is provided with a main body mechanism 4, which includes a clamping part for fixing wires and a connecting part connected to the clamping part. The connecting part extends from the inside of the mounting mechanism 2 to its outside.

[0033] Combination Figure 1 and Figure 2 As shown, adjacent terminals are installed together in a detachable manner. When one of the terminals is damaged, only that terminal needs to be removed and replaced with a new one, without having to replace the entire terminal block. This avoids the need to replace the entire terminal block when it is damaged, which is a common problem with traditional terminal blocks. The modular design and flexible combination significantly improve the practicality and ease of maintenance of the terminal block.

[0034] Furthermore, the installation mechanism 2 includes a lower protective shell 203. A slider 202 extending along its length is provided on one side of the lower protective shell 203, and a groove 204 is provided on the other side. Two adjacent wiring terminals are connected by the cooperation of the slider 202 and the groove 204.

[0035] like Figure 2 As shown, the main body 4 is set inside the lower protective shell 203; when installing the terminal block, the slider 202 of an adjacent terminal block is inserted into the groove 204 of another terminal block. Users can flexibly assemble the terminal blocks according to actual needs to form terminal blocks of different lengths and functions.

[0036] As an optional implementation, the splicing terminal block also includes a mounting rail 3, and the bottom of the lower protective housing 203 is provided with a mounting groove 205 extending in the width direction, and the mounting groove 205 slides in conjunction with the mounting rail 3.

[0037] Combination Figure 1 and Figure 2 As shown, after adjacent terminals are spliced ​​together, the two terminal blocks are arranged along their length without any limit on their position. To prevent the terminals from shifting and to ensure they remain flush and aligned, a mounting rail 3 is inserted at the bottom of the terminal block, thus achieving relative fixation between the terminals. When it is necessary to replace a terminal or add a new terminal, the mounting rail 3 must be removed before replacing or installing the new terminal.

[0038] In some embodiments, the main body mechanism 4 includes a wiring frame 402, a lower clamping plate 404 disposed inside the wiring frame 402, an upper clamping plate 403 disposed on the lower clamping plate 404, and a fastener 401 slidably disposed on the top of the wiring frame 402. The heads of the upper clamping plate 403 and the lower clamping plate 404 are U-shaped to form a clamping part, and the tail of the lower clamping plate 404 is a connecting part.

[0039] Combination Figure 3 and Figure 4 As shown, the main body mechanism 4 is mainly used for connecting wires. The upper clamping plate 403 and the lower clamping plate 404 are both made of metal with good conductivity. The clamping part formed by the fixed connection of the upper clamping plate 403 and the lower clamping plate 404 is elastic. The fastener 401 abuts against the upper clamping plate 403. When installing the wire, the wire is inserted into the opening of the clamping part. By sliding the fastener 401, the upper clamping plate 403 is pressed downward until the wire is pressed onto the lower clamping plate 404 and fixed.

[0040] As an optional implementation, fastener 401 is a fastening bolt, which is screwed onto the wiring frame 402, and the bottom of the fastening bolt abuts against the upper clamping plate 403.

[0041] like Figure 2 As shown, the fastening bolt can be rotated to move up and down on the wiring frame 402, thereby pressing or loosening the upper clamping plate 403.

[0042] In some embodiments, the upper cover mechanism 1 includes an upper protective shell 102 and a cover plate 101. The upper protective shell 102 is provided with an upper protective rubber ring 103 at its head and the lower protective shell 203 is provided with a lower protective rubber ring 201 at its head. When the upper protective shell 102 is fastened to the lower protective shell 203, the upper protective rubber ring 103 and the lower protective rubber ring 201 are engaged.

[0043] like Figure 5As shown, a cover plate 101 is fixedly installed on the top of the upper protective shell 102. The head of the upper protective shell 102 (i.e. the end facing the wire) is provided with an opening, and an upper protective rubber ring 103 is provided at the opening. The head of the lower protective shell 203 is provided with a lower protective rubber ring 201. Both the upper protective rubber ring 103 and the lower protective rubber ring 201 are made of rubber, which can ensure that the wire passes through smoothly while fixing the wire and increasing the dustproof effect inside the terminal block.

[0044] Furthermore, the tail of the upper protective shell 102 is hinged to the tail of the lower protective shell 203.

[0045] To increase ease of operation, the upper protective shell 102 and the lower protective shell 203 are hinged together. When fixing or removing the wires, the main body mechanism 4 can be exposed simply by rotating the upper protective shell 102, which facilitates operation.

[0046] As an optional implementation, the upper protective shell 102 has an insertion block 106 at the bottom of its head, and the lower protective shell 203 has a slot 206 at its top that can cooperate with the insertion block 106.

[0047] Combination Figure 2 and Figure 5 As shown, by setting the insert 106 and the slot 206, when the upper protective shell 102 is fastened to the lower protective shell 203, the insert 106 can be inserted into the slot 206, and the two are interference fit, which can realize the relative fixation of the upper protective shell 102 and the lower protective shell 203.

[0048] In some embodiments, the cover mechanism 1 further includes a protective film 104 disposed at the bottom of the cover plate 101, and flame retardant powder 105 is disposed inside the protective film 104.

[0049] like Figure 6 As shown, by providing an upper cover plate 101, combined with a protective film 104 and flame retardant powder 105, when a short circuit occurs inside the terminal block and the temperature rises, the protective film 104 melts and the internal flame retardant powder 105 is released, covering the wiring area to retard flames and ensuring the safety of the terminal block.

[0050] Furthermore, the protective film 104 is made of hot melt adhesive film material.

[0051] The hot melt adhesive material has a low melting point. When a short circuit occurs inside the terminal and the temperature rises, the protective film 104 can melt more quickly and release the flame retardant powder 105, thereby improving the safety of the terminal.

[0052] Working Principle: When using this device, the number and specifications of the wires to be connected must first be determined according to the actual needs of the hydropower station's computer monitoring system. The number of terminal blocks to be combined must also be determined. After this is determined, multiple installation mechanisms 2 are combined using sliders 202 and grooves 204. The slider 202 of one installation mechanism 2 is inserted into the groove 204 of another installation mechanism 2, and multiple installation mechanisms 2 are connected sequentially to form the required terminal block length. The combined installation mechanisms 2 are placed on the installation track 3 through the installation groove 205. After installation, the upper cover mechanism 1 is flipped up to expose the internal main body mechanism 4. The wires to be connected are inserted into the wiring frame 402 through the lower protective rubber ring 201, ensuring the wires are positioned between the upper clamping plate 403 and the lower clamping plate 404. The screws are tightened with a screwdriver to press down the upper clamping plate 403, firmly clamping the wires between the upper and lower clamping plates 403 and 404. After connection, the upper cover mechanism 1 is replaced with the main body mechanism 4, ensuring the upper cover mechanism 1... It can fit tightly against the main body 4, providing protection and ensuring that the upper protective rubber ring 103 and the lower protective rubber ring 201 protect the wiring connection, effectively preventing dust and moisture from entering the terminal. If a terminal is found to be damaged, the damaged terminal can be removed from the mounting rail 3, disassembled through the slide groove 204 and slider 202, and then replaced with a new terminal. At the same time, a protective film 104 is provided at the bottom of the upper cover plate 101. The protective film 104 is filled with flame retardant powder 105. The protective film 104 is made of hot melt adhesive film material. When a short circuit occurs inside the terminal or the temperature rises abnormally, the hot melt adhesive film will melt and release the flame retardant powder 105, covering the wiring part and playing a role in flame retardancy and protection.
