Technical Field

[0001] This application relates to the technical field of terminals, and in particular to a modular terminal block. Background Technology

[0002] Terminal blocks, as key components for electrical connections, are widely used in power systems, communication systems, and other fields. With continuous development, the requirements for the reliability and convenience of terminal blocks are becoming increasingly stringent, while also demanding that they possess the characteristics of quick installation and removal to improve work efficiency.

[0003] Existing terminal blocks generally include a wiring port, a conductive structure set in the terminal housing, an unlocking button for unlocking the wiring port to remove the wire, and a connection structure for connecting different conductive structures. Most terminal block connection structures are difficult to operate and require tools for fixing and unlocking. Especially when the terminal blocks need to be connected to electronic devices through embedded installation, the operation of the connection structure will affect the assembly efficiency. Utility Model Content

[0004] In order to provide a terminal block that can be quickly assembled and is easy to use, this application provides a modular terminal block.

[0005] This application provides a modular terminal block, which adopts the following technical solution:

[0006] A modular terminal block includes a terminal housing with wiring grooves for wire insertion on both end faces. It also includes a fixing assembly for fixing the terminal housing to a device. The fixing assembly includes a fixing spring and a positioning seat. The positioning seat is disposed on the side wall of the terminal housing. The fixing spring includes a pressing part, a plugging part, and a connecting part connected to each other. The plugging part is plugged into the positioning seat and fixes the fixing spring to the side wall of the terminal housing. The pressing part and the connecting part are respectively connected to both ends of the plugging part. When the pressing part is pressed, the connecting part can be driven to rotate away from the terminal housing and inserted into the corresponding device. When the pressing part is released, the connecting part rotates towards the terminal housing and is fixedly connected to the device.

[0007] By adopting the above technical solution, the design of the fixing component allows the terminal block to be easily and quickly fixed in the equipment. By pressing the pressing part, the connecting part is driven to rotate and be inserted into the equipment, and then the pressing part is released to achieve fixation. This process requires no additional tools and is simple and quick to operate.

[0008] Optionally, the plug-in part is a rectangular metal piece, and the positioning seat has a plug-in groove for the plug-in part to pass through. The end of the plug-in part is inclined away from the terminal housing. When the plug-in part is inserted into the plug-in groove, the side wall of the plug-in part abuts against the side wall of the plug-in groove.

[0009] Optionally, the pressing part is a "U"-shaped plate.

[0010] By adopting the above technical solution, the design of the "U"-shaped plate as the pressing part allows users to apply force more comfortably during operation.

[0011] Optionally, it also includes a positioning block, a first spring, and a second spring disposed within the terminal housing. One end of the first spring and the second spring abuts against each other. The positioning block is disposed at the two opposite ends of the first spring and the second spring, and fixes the first spring and the second spring within the terminal housing. Each of the opposite ends of the first spring and the second spring is provided with a snap-fit ​​piece. The snap-fit ​​piece extends obliquely toward the connection point of the first spring and the second spring. The wiring groove is formed on the positioning block and extends to the upper and lower side walls of the positioning block.

[0012] By adopting the above technical solution, a compact and stable modular terminal block is provided. The positioning block, first and second spring contacts, and snap-fit ​​contacts located within the terminal housing ensure a stable clamping force when the wire is inserted into the wiring slot, guaranteeing both a secure connection and facilitating quick wire insertion. Furthermore, the addition of fixing components allows the terminal to be securely installed in the equipment, improving overall safety and reliability.

[0013] Optionally, a snap-fit ​​block is provided on the side wall of the positioning block, and the snap-fit ​​block has a chamfer on the side facing the first spring piece. A snap-fit ​​groove is provided on the side wall of the terminal housing for the snap-fit ​​block to snap into.

[0014] By adopting the above technical solution, a snap-fit ​​block is added to the side wall of the positioning block and a chamfer is provided, which facilitates the quick and accurate snap-fit ​​between the snap-fit ​​block and the snap-fit ​​groove on the terminal housing, thereby improving the convenience and efficiency of assembly.

[0015] Optionally, the first spring has two opposing metal springs at one end near the second spring, with their sidewalls abutting against each other, and the second spring can be inserted between the two metal springs.

[0016] By adopting the above technical solution, the first contact spring uses a bimetallic contact spring design, allowing the second contact spring to be inserted between them, forming a tighter contact. This design not only improves conductivity but also enhances the stability of the connection.

[0017] Optionally, two sets of the positioning block, the first spring and the second spring are provided in the terminal housing, and the two positioning blocks located at the same end are fixedly connected to each other.

[0018] By adopting the above technical solution, and by setting two sets of positioning blocks, a first spring and a second spring in the terminal housing, this design also facilitates the simultaneous connection and management of multiple lines, improving wiring efficiency; at the same time, it also improves the compactness of the terminal design and increases space utilization.

[0019] Optionally, the insertion part consists of two parallel metal plates, and two positioning seats are provided. The two positioning seats have insertion grooves on their side walls for the insertion part to pass through. The insertion part has a chamfer at its end, and a slot is provided on the side wall of the insertion part facing the positioning seat. When the insertion part passes through the insertion groove, the upper and lower side walls of the slot abut against the upper and lower surfaces of the positioning seat, respectively.

[0020] By adopting the above technical solution, the insertion part uses a design of two parallel metal plates, and is equipped with a slot that matches the insertion slot on the positioning seat, making the insertion process more precise and stable. The abutment design between the upper and lower side walls of the slot and the surface of the positioning seat further enhances the tightness and stability of the connection.

[0021] Optionally, the pressing part is a "T"-shaped metal plate.

[0022] By adopting the above technical solution, it is possible to adapt to the design of the plug part, and it is also convenient to press.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. Through modular design and precise matching of components, the terminal block structure is made compact and stable, improving the convenience and efficiency of connection;

[0025] 2. The design of the fixing components allows the terminal blocks to be easily and quickly fixed in the equipment without additional tools, improving the efficiency of installation and disassembly. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] Example 1:

[0036] This application discloses a modular terminal block. (Refer to...) Figure 1 and Figure 2 The terminal block includes a terminal housing 1, which has a slender rectangular structure for easy insertion into electronic devices. Both the upper and lower end faces of the terminal housing 1 have wiring slots 11 for wire insertion. The terminal block also includes a positioning block 2, a first spring 3, and a second spring 4 disposed within the terminal housing 1. The ends of the first spring 3 and the second spring 4 that are close to each other abut against each other. The positioning block 2 is respectively disposed at the opposite ends of the first spring 3 and the second spring 4, and the positioning block 2 fixes the first spring 3 and the second spring 4 within the terminal housing 1.

[0037] Reference Figure 2 and Figure 3 Specifically, the first spring 3 and the second spring 4 are made of conductive metal plates. The ends of the two springs that are far apart from each other have the same structure. Taking the first spring 3 as an example, the upper end of the first spring 3 is bent in an upward direction. The terminal housing 1 is provided with a boss for the lower surface of the upper part of the first spring 3 to abut. A stack of first springs 3 forms a support. The bent part of the first spring 3 is provided with a snap-fit ​​piece 5, which is inclined towards the second spring 4. The wiring groove 11 is opened on the positioning block 2 and passes through the positioning block 2 in a vertical direction. The snap-fit ​​piece 5 is located at the lower end of the wiring groove 11, so that when the wire is inserted from the wiring groove 11, the wire can be quickly fixed by the snap-fit ​​piece 5, so that the wire is connected to the first spring 3.

[0038] Reference Figure 2 and Figure 3Correspondingly, the end of the second spring 4 furthest from the first spring 3 is also provided with a clamping piece 5 for clamping the wire. Furthermore, the end of the first spring 3 near the second spring 4 has two opposing metal springs with their sidewalls abutting against each other; this design makes clamping the wire more stable. The second spring 4 can be inserted between the two metal springs, ensuring a secure abutment between the first spring 3 and the second spring 4, and providing a stable clamping force during use.

[0039] Reference Figure 2 and Figure 3 In this embodiment, a snap-fit ​​block 21 is fixed on the side wall of the positioning block 2. The snap-fit ​​block 21 is a rectangular block with a chamfer on the side facing the first spring piece 3, which facilitates the insertion of the positioning block 2 into the terminal housing 1 during assembly. To improve stability, the positioning block 2 and the snap-fit ​​block 21 are preferably integrally formed, and the snap-fit ​​block 21 can be respectively provided on two parallel side walls of the positioning block 2. Optionally, to improve the compactness of the overall structure, two sets of positioning blocks 2, the first spring piece 3, and the second spring piece 4 are provided in the terminal housing 1, and the two positioning blocks 2 located at the same end are fixedly connected to each other.

[0040] Reference Figure 1 and Figure 4 In this embodiment, the terminal block further includes a fixing assembly for fixing the terminal housing 1 within the device. The fixing assembly includes a fixing spring 6 and a positioning seat 7. The positioning seat 7 is fixed to the side wall of the terminal housing 1 and is located at one end near the first spring 3; the fixing spring 6 includes a pressing part 61, a plugging part 62, a connecting part 63, and a spring-loaded part 64 connected to each other. The plugging part 62 and the positioning seat 7 are mutually plugged in to fix the fixing spring 6 to the side wall of the terminal housing 1; the pressing part 61 and the connecting part 63 are respectively connected to the upper and lower ends of the spring-loaded part 64; at the same time, the inner side of the spring-loaded part 64 is connected to the plugging part 62 through two arc-shaped pieces.

[0041] Specifically, in this embodiment, the insertion part 62 is a rectangular metal sheet, and the positioning seat 7 has an insertion groove 71 along the vertical direction for the insertion part 62 to be inserted into. In order to maintain the stability of the connection between the insertion part 62 and the positioning seat 7, the end of the insertion part 62 is inclined and bent away from the terminal housing 1. When the insertion part 62 is inserted into the insertion groove 71, the side wall of the insertion part 62 abuts against the side wall of the insertion groove 71. The spring-loaded part 64 is an arc-shaped plate, which is provided on both sides of the insertion part 62. The outer arc surface of the spring-loaded part 64 abuts against the side wall of the terminal housing 1. The sides of the two spring-loaded parts 64 that are close to each other are connected to the insertion part 62 through the arc-shaped plate.

[0042] The pressing part 61 is preferably U-shaped, with its opening facing downwards and both ends connected to the upper ends of the two spring-loaded parts 64 respectively. Its U-shaped structure ensures ease of pressing. The connecting part 63 is connected to the lower end of the spring-loaded part 64. The distal end of the connecting part 63, away from the spring-loaded part 64, has a portion bent towards the terminal housing 1, and the outer arc surface of this bent portion abuts against the terminal housing 1. The corresponding device includes components that connect and cooperate with the connecting part 63. The insertion and cooperation method between the connecting part 63 and the device is existing technology and will not be described in detail here. Since the terminal housing 1 is formed by two outer shells interlocking, to facilitate the installation and fixing of the spring piece 6, the distal end of the connecting part 63 has an arc surface, and a chamfer is provided at the connection point of the two outer shells to facilitate the passage of the connecting part 63 through this connection point.

[0043] When the plug part 62 is inserted into the positioning seat 7, there is a gap between the pressing part 61 and the side wall of the terminal housing 1, the outer wall of the spring-loaded part 64 abuts against the side wall of the terminal housing 1, and the bent part at the far end of the connecting part 63 abuts against the terminal housing. When the pressing part 61 is pressed, the connecting part 63 can rotate around the abutment point between the spring-loaded part 64 and the terminal housing 1 as the pivot, thereby driving the connecting part 63 to rotate away from the terminal housing 1. At this time, the terminal is inserted into the corresponding device, and then the pressing part 61 is released. The connecting part 63 rotates back towards the terminal housing 1 and is fixedly connected to the device.

[0044] The implementation principle of the modular terminal block in this application embodiment is as follows: The modular terminal block fixes the positioning block 2, the first spring 3, and the second spring 4 into the terminal housing 1, forming a simple and compact terminal body. In use, simply insert the wire into the wiring slot 11, then press the pressing part 61 to insert the terminal into the device, and release the pressing part 61 to connect the corresponding wire and terminal. The operation is convenient and quick.

[0045] Example 2:

[0046] The difference between this embodiment and Embodiment 1 lies in the positioning base 7, the insertion part 62, and the pressing part 61. (Refer to...) Figure 5 and Figure 6 Specifically, the plug-in part 62 consists of two parallel metal pieces. The lower end of the plug-in part 62 is chamfered, and a slot is formed on the side of the two plug-in parts 62 that are close to each other. There are two positioning seats 7 fixed on the side wall of the terminal housing 1. The side of the two positioning seats 7 that are close to each other is provided with a plug-in groove 71 for the plug-in part 62 to pass through. When the plug-in part 62 moves downward and passes through the plug-in groove 71, the upper surface of the plug-in groove 71 in the plug-in part 62 abuts against the upper surface of the positioning seat 7, and the lower surface of the plug-in groove 71 in the plug-in part 62 abuts against the lower surface of the positioning seat 7, thereby locking the plug-in part 62 and the positioning seat 7 and fixing the fixing spring 6 on the positioning seat 7.

[0047] In this embodiment, the pressing part 61 is configured as a "T" shaped structure, so as to ensure convenient pressing while also corresponding to the structural configuration of the two plug-in parts 62.

[0048] The implementation principle of a modular terminal block in this application embodiment is as follows: when the plug part 62 passes through the plug groove 71 and the two are engaged, the stability of the fixing spring 6 fixed on the positioning seat 7 can be improved, thereby increasing the stability of the entire terminal block during plug-in use.

[0049] Example 3:

[0050] The difference between this embodiment and Embodiment 2 lies in the structure of the positioning base 7 and the insertion part 62. (Refer to...) Figure 7 The plug-in portion 62 also consists of two parallel metal pieces. The lower end of the plug-in portion 62 is chamfered, and a slot is provided on the side of the two plug-in portions 62 that are opposite to each other. There are two positioning seats 7 fixed on the side wall of the terminal housing 1. The side of the two positioning seats 7 that are opposite to each other is provided with a plug-in groove 71 for the plug-in portion 62 to pass through. When the plug-in portion 62 moves downward and passes through the plug-in groove 71, the upper surface of the plug-in groove 71 in the plug-in portion 62 abuts against the upper surface of the positioning seat 7, and the lower surface of the plug-in groove 71 in the plug-in portion 62 abuts against the lower surface of the positioning seat 7, thereby locking the plug-in portion 62 and the positioning seat 7 and fixing the fixing spring 6 on the positioning seat 7.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
