Description

Technical Field

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

[0002] In existing electrical connection technologies, screw-type crimp terminals are widely used. These terminals require manual tightening of screws to secure the wires, a cumbersome installation process that is not only inefficient but also prone to loosening due to vibration or thermal expansion and contraction over time, eventually leading to poor contact. To improve operational efficiency, quick-connect terminals have been proposed, which only require inserting the connector into the connection channel to complete the conductive connection. However, this structure often relies solely on a single snap-fit ​​positioning or frictional fixation, making it susceptible to loosening or even detachment under vibration, thus compromising the reliability of the electrical connection. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a terminal block module and terminal block, which, by setting an elastic limiting component, a limiting slot and an elastic clamping component, enables the plug to be securely locked in the plug channel, so that no additional tools are needed for quick plugging and connection, and the terminal block can be prevented from loosening due to vibration and impact.

[0004] This utility model provides a terminal block module, including a plug-in base with an internal plug-in channel and a plug-in component that matches the plug-in channel. The side of the plug-in component is provided with an elastic limiting component along the circumferential direction. The inner wall of the plug-in channel is provided with a limiting groove that matches the elastic limiting component. The two sides of the plug-in base are respectively provided with elastic clamping components that press against the plug-in channel.

[0005] In one of the alternative technical solutions, the elastic limiting component includes an elastic locking arm, the elastic locking arm having a structure in which the width gradually increases from bottom to top, the lower end of the elastic locking arm being connected to the outer periphery of the plug-in, and the structure of the limiting slot matching the structure of the elastic locking arm.

[0006] In one of the alternative technical solutions, the elastic limiting component includes a plurality of elastic locking arms sequentially disposed on the outer periphery of the connector.

[0007] In one of the alternative technical solutions, the elastic limiting component includes two continuously arranged elastic locking arms, and the insertion channel is correspondingly provided with two continuously arranged limiting slots.

[0008] In one of the alternative technical solutions, the elastic limiting component includes a spring piece whose lower end is connected to the outer surface of the connector, the upper end of the spring piece does not contact the connector, and multiple spring pieces are evenly arranged circumferentially on the side of the connector.

[0009] In one of the alternative technical solutions, the upper and lower ends of the insertion channel are respectively provided with deformation gaps, and the upper and lower ends of the insertion channel are respectively composed of separate horizontal plates.

[0010] In one of the alternative technical solutions, the socket is formed by detachably connecting at least two socket elements.

[0011] In one of the alternative technical solutions, the socket is composed of three detachable socket elements connected together, and the socket has two plug-in channels.

[0012] In one of the alternative technical solutions, the upper end of the connector is covered with an insulating sheath.

[0013] This utility model provides a terminal block, including a base and a terminal block module as described above connected to the base. The base is provided with a guide rail, and the lower end face of the plug in the terminal block module is provided with a guide rail groove that matches the guide rail.

[0014] The above technical solution has the following beneficial effects:

[0015] The terminal block module provided by this utility model features an elastic limiting component on the side of the connector and a limiting groove that mates with the elastic limiting component on the inner wall of the connector channel. This allows the connector to be smoothly inserted into the connector channel, and the limiting groove then limits the elastic limiting component, ensuring the connector is securely attached to the connector channel without the need for additional tools. Elastic clamping elements that apply pressure to the connector channel are also provided on both sides of the connector, providing additional radial clamping force on top of the limiting force, thus preventing the terminal block module from loosening or even falling off under vibration.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] In this utility model, unless otherwise explicitly specified and limited, the term "fixed" and similar terms should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1-3 As shown, a terminal block module provided in one embodiment of the present invention includes a plug-in base 1 with an internal plug-in channel 11 and a plug-in component 2 that matches the plug-in channel 11. An elastic limiting component 3 is provided on the side of the plug-in component 2 along the circumferential direction. A limiting groove 12 that matches the elastic limiting component 3 is provided on the inner wall of the plug-in channel 11. An elastic pressing component 4 that presses against the plug-in channel 11 is provided on both sides of the plug-in base 1.

[0030] During the insertion process, the connector 2 is accurately positioned by entering the limiting slot 12 through the elastic limiting component 3. After the connector 2 is in place, the elastic clamping components 4 on both sides of the connector 1 continuously apply pressure towards the insertion channel 11, further clamping the connector 2 on top of the limiting position. Through the combination of limiting and clamping, the connector 2 can maintain a stable connection during long-term use, avoiding loosening caused by vibration or thermal expansion and contraction, thereby ensuring the reliable electrical connection of the terminal block module.

[0031] Preferably, the insertion seat 1 is provided to accommodate the accommodating cavity of the elastic clamping member 4. The elastic clamping member 4 is a wave-shaped elastic pressure plate, which is disposed in the accommodating cavities on both sides of the insertion seat 1 to continuously apply uniform pressure to both sides of the insertion channel 11, ensuring that the insertion channel 11 can lock the insertion member 2 from both sides after the insertion member 2 is inserted.

[0032] In summary, the terminal block module provided in this embodiment of the present invention has an elastic limiting component 3 on the side of the plug-in 2 and a limiting slot 12 that cooperates with the elastic limiting component 3 on the inner wall of the plug-in channel 11, so that the plug-in 2 can be smoothly inserted into the plug-in channel 11. Then, the elastic limiting component 3 is limited by the limiting slot 12, so that the plug-in can be stably connected to the plug-in channel 11 without the need for additional tools.

[0033] In addition, elastic clamping members 4 are provided on both sides of the plug socket 1 to apply clamping force to the plug channel 11, so that the plug 2 is subjected to additional radial clamping force on the basis of being limited, thereby preventing the terminal module from easily loosening or even falling off in a vibration environment.

[0034] In one embodiment, the elastic limiting component 3 of the terminal block module includes an elastic locking arm 31, which has a structure in which the width gradually increases from bottom to top. The lower end of the elastic locking arm 31 is connected to the outer periphery of the plug-in 2, and the structure of the limiting slot 12 matches the structure of the elastic locking arm 31.

[0035] In this embodiment, when the connector 2 is inserted into the connector channel 11, the elastic locking arm 31 is gradually compressed and guided into the limiting slot 12 during the insertion process. After the connector 2 is fully inserted, the elastic locking arm 31 restores its elastic deformation and locks into the limiting slot 12, forming a reliable mechanical lock to ensure that the connector 2 will not shift position during use.

[0036] In one embodiment, the elastic limiting component 3 of the terminal block module includes a plurality of elastic locking arms 31 arranged sequentially on the outer periphery of the plug 2.

[0037] In this embodiment, multiple elastic locking arms 31 are distributed along the outer periphery of the connector 2. When the connector 2 is inserted into the connector channel 11, it can simultaneously engage with the limiting slot 12 in multiple directions to achieve multi-point limiting. Through the combined action of multiple elastic locking arms 31, the fixing state of the connector 2 in the connector seat 1 is more balanced and stable, effectively avoiding local loosening caused by insufficient force on a single elastic locking arm 31, thereby ensuring that the connection remains tight even under vibration.

[0038] In one embodiment, the elastic limiting component 3 of the terminal block module includes two continuously arranged elastic locking arms 31, and the insertion channel 11 is correspondingly provided with two continuously arranged limiting slots 12.

[0039] In this embodiment, when the connector 2 is inserted, two consecutively arranged elastic locking arms 31 sequentially enter two consecutively arranged limiting slots 12, forming a double-point limiting structure. The double-point limiting structure enables the connector 2 to achieve a stronger positioning effect in the longitudinal direction, avoiding the displacement of the connector 2 caused by single-point locking, and further improving the vibration resistance and reliability of the terminal block module.

[0040] In one embodiment, the elastic limiting component 3 of the terminal block module includes a spring piece whose lower end is connected to the outer surface of the connector 2, and whose upper end does not contact the connector 2. Multiple spring pieces are evenly arranged circumferentially on the side of the connector 2. In this embodiment, the spring piece undergoes elastic deformation when the connector 2 is inserted into the insertion channel 11 and engages with the limiting slot 12 to form a circumferential limiting and radial clamping of the connector 2. Through this structure, the connector 2 can not only maintain stable conductive contact but also achieve a certain degree of adaptive adjustment when there are manufacturing errors or assembly deviations, thereby ensuring the assembly accuracy and connection reliability of the terminal block module under actual working conditions.

[0041] In one embodiment, the upper and lower ends of the insertion channel 11 are respectively provided with deformation gaps 13, and the upper and lower ends of the insertion channel 11 are respectively composed of separate horizontal plates.

[0042] In this embodiment, the deformation gap 13 and the separation plate structure enable the insertion channel 11 to generate appropriate deformation buffer during the insertion and removal of the connector 2, reducing the frictional resistance during insertion and removal. The structure of the deformation gap 13 and the separation plate not only improves the insertion and removal feel, but also prevents the connector 2 from getting stuck due to uneven force during insertion, ensuring smooth insertion operation.

[0043] In one embodiment, the socket 1 is formed by at least two socket elements that can be detachably connected.

[0044] In this embodiment, the connector 1 can be disassembled as needed during production, assembly, or maintenance. Individual connector components can be replaced separately if damaged, avoiding the need for complete replacement. Furthermore, the connector 2 can be released from the connector channel 11 by disassembling the connector unit, improving the flexibility of the wiring terminals. Preferably, the connector units are connected by fasteners to prevent separation during use from affecting the electrical connection.

[0045] In one embodiment, the socket 1 is composed of three detachable socket elements, and the socket 1 has two plug-in channels 11.

[0046] In this embodiment, the three socket elements are spliced ​​together to form an integral structure, providing two independent insertion channels 11 within a limited space. The structure of splicing and combining the three socket elements allows each side of the two insertion channels 11 to be composed of different socket units, ensuring that each insertion channel 11 has sufficient deformation space, and the parallel arrangement of the two insertion channels 11 can improve the space utilization of the insertion socket 1.

[0047] In one embodiment, the upper end of the connector 2 is covered with an insulating sheath 21.

[0048] In this embodiment, the insulating sleeve 21 provides additional insulation protection for the connector 2, preventing users from directly contacting conductive parts during operation and improving safety. Simultaneously, the insulating sleeve 21 prevents external dust and impurities from entering the connector area, ensuring the stability of the terminal block module during long-term operation.

[0049] Some embodiments of this utility model also provide a terminal block, which includes a base 5 and a wiring terminal module connected to the base 5. The base 5 is provided with a guide rail 51, and the lower end face of the plug-in 1 in the wiring terminal module is provided with a guide rail groove 14 that matches the guide rail 51.

[0050] The terminal block module can be quickly slid into and fixed on the base 5 along the guide rail 51, and can also be disassembled via the guide rail 51. The cooperation between the guide rail 51 and the guide rail groove 14 not only simplifies the assembly process, but also allows the terminal block to be quickly maintained, replaced or expanded, facilitating flexible configuration in different applications.

[0051] Preferably, the guide rail groove 14 has a dovetail groove structure, and the guide rail 51 on the base 5 is a dovetail track. The dovetail groove structure can withstand large vertical and lateral loads, making it suitable for terminal block structures and ensuring a stable connection between the base 5 and the terminal block module. Other structures of the terminal block refer to existing technologies and will not be described in detail here.

[0052] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0053] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
