Description
Technical Field
[0001] This utility model relates to a terminal block structure, and more particularly to a pluggable terminal block with quick-release fasteners. Background Technology
[0002] Terminal blocks are a common type of connection component, and are currently widely used in fields such as industrial communications with large amounts of information, industrial equipment with tight integration between devices, the power industry to improve the reliability and security of power systems, and highly automated industrial control.
[0003] In order to enable terminal blocks to have advantages such as quick installation and easy maintenance, a pluggable terminal block that combines wiring and circuit board has appeared on the market. It includes pluggable female and male terminal blocks to achieve the function of quick plugging and unplugging of female and male terminal blocks.
[0004] However, if the connection between the female and male terminal blocks is prone to loosening, it will affect the stability of signal and current transmission. Therefore, a locking structure is provided between the female and male terminal blocks. Thus, how to make the locking structure of the pluggable terminal block have quick-release and quick-assembly functions, while maintaining the advantage of a compact size, is the focus of the inventor's research and development.
[0005] In view of this, the inventor has devoted himself to researching and applying theoretical principles to address the aforementioned problems in the prior art, which is the goal of the inventor's development. Utility Model Content
[0006] This utility model provides a pluggable terminal block with a quick-release locking fastener. The quick-release locking fastener has a handle, multiple locking hooks extending from the handle, and multiple reset arms extending from each locking hook. Each locking hook and each set of arms is movably accommodated in a receiving part. Multiple terminal slots are arranged at equal intervals, and each receiving part is formed between two adjacent terminal slots. This allows the pluggable terminal block of this utility model to have the advantages of quick unlocking and maintaining a compact number and size of terminal slots.
[0007] In this embodiment of the present invention, a pluggable terminal block with a quick-release locking fastener is provided, comprising: a female terminal block having a plurality of locking portions; a male terminal block detachably pluggable into the female terminal block, the male terminal block comprising: a male block body having an insulating housing having a plurality of terminal slots and a plurality of receiving portions, the plurality of terminal slots being equally spaced from each other, and each receiving portion being formed between two adjacent terminal slots; and a quick-release locking fastener pivotally connected to the insulating housing. The quick-release fastener has a handle, multiple locking hooks extending from the handle, and multiple reset arms extending from each locking hook. The handle is exposed outside the insulating housing. Each locking hook and each reset arm is movably accommodated in its respective accommodating portion, and each reset arm abuts against the inner wall of its respective accommodating portion. When each reset arm is reset, it causes each locking hook to engage with its respective locking portion. When the handle is rotated, it causes each reset arm to undergo elastic deformation and each locking hook to disengage from its respective locking portion.
[0008] Based on the above, this utility model uses a quick-release locking fastener consisting of a handle driving multiple locking hooks and multiple reset spring arms, which can quickly unlock the terminal female and terminal male sockets and has excellent locking strength. Furthermore, each locking hook and each reset spring arm is installed in a receiving part formed between multiple terminal slots using an insulating shell, so that the pluggable terminal block of this utility model has the advantages of maintaining a compact size and a limited number of terminal slots.

[0052] The detailed description and technical content of this utility model will be explained below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this utility model.
[0053] Please refer to Figures 1 to 14 As shown, this utility model provides a pluggable terminal block with quick-release fasteners. This pluggable terminal block 10 mainly includes a female terminal 1 and a male terminal 2.
[0054] like Figures 9 to 14 As shown, the terminal female 1 is provided with multiple slots 11 and multiple locking parts 12, as detailed below. Each slot 11 has a first terminal (not shown in the figure), and each locking part 12 is a locking groove 13 opened from the inner wall of each slot 11.
[0055] like Figures 1 to 14 As shown, the male terminal 2 can be detachably inserted into the female terminal 1, that is, the male terminal 2 can be inserted into the female terminal 1, and the male terminal 2 can also be detached from the female terminal 1. The male terminal 2 includes a male body 21 and a quick-release locking fastener 22.
[0056] In addition, the main body 21 of the male connector includes an insulating housing 211 and a plurality of second terminals (not shown in the figure). The insulating housing 211 is provided with a plurality of terminal slots 212 and a plurality of receiving portions 213. The plurality of terminal slots 212 are arranged at equal intervals. Each receiving portion 213 is formed between two adjacent terminal slots 212. Each second terminal is embedded in each plurality of terminal slots 212. The top opening of each terminal slot 212 is used to provide cable (not shown in the figure) insertion.
[0057] The details are as follows: the insulating housing 211 has a plurality of plugs 214, each terminal slot 212 is formed inside each plug 214, and a plurality of receiving portions 213 are a plurality of spacers S formed between two adjacent plugs 214 respectively. The insulating housing 211 extends with a plurality of vertical partitions 5 and a plurality of horizontal partitions 7 respectively disposed inside each spacer S. Each horizontal partition 7 is provided with a limiting hole 71. The insulating housing 211 is also provided with a plurality of pivot holes 6 respectively disposed inside each spacer S.
[0058] The insulating housing 211 includes an upper housing 3 and a lower housing 4 connected to each other. The upper half of a plurality of plugs 214 is formed in the upper housing 3 and the lower half is formed in the lower housing 4. A plurality of vertical partitions 5 extend from the upper housing 3. A plurality of pivot holes 6 are opened from the lower housing 4. A plurality of transverse partitions 7 extend from the lower housing 4.
[0059] Furthermore, the quick-release locking fastener 22 is pivotally connected to the insulating housing 211. The quick-release locking fastener 22 has a handle 221, multiple locking hooks 222 extending from the handle 221, and multiple return spring arms 223 extending from each locking hook 222. The handle 221 is exposed outside the insulating housing 211. Each locking hook 222 and each return spring arm 223 is movably accommodated in each accommodating portion 213, and each return spring arm 223 abuts against the inner wall of each accommodating portion 213. The width H of each locking hook 222 and each return spring arm 223 is 1 to 2 mm.
[0060] Further explanation is as follows: Each locking hook 222 has an L-shaped segment 224 extending from the handle 221, a I-shaped segment 225 extending from the end of the L-shaped segment 224 away from the handle 221, and a tenon 226 extending from the I-shaped segment 225 away from the L-shaped segment 224. Each L-shaped segment 224 has a pivot 227 extending from both sides of the end adjacent to the I-shaped segment 225. Each pivot 227 is pivotally connected to each pivot hole 6. Each I-shaped segment 225 passes through each limiting hole 71. Each reset spring arm 223 is an oblique spring arm 8 extending from the inside of each L-shaped segment 224.
[0061] Furthermore, the handle 221 in this embodiment is a pressable handle 9, and each inclined spring arm 8 is disposed between the pressable handle 9 and each straight partition 5, with the end of each inclined spring arm 8 abutting against each straight partition 5.
[0062] However, the form of the handle 221 is not limited to this embodiment. The handle 221 can be a lever handle. The above-mentioned vertical partitions 5 are instead arranged between the lever handle and the oblique spring arms 8, with the ends of the oblique spring arms 8 abutting against the vertical partitions 5.
[0063] Furthermore, in this embodiment, the quick-release fastener 22 is first installed in the gap S between the plugs 214 of the lower housing 4, and then the upper housing 3 is closed to the lower housing 4 to complete the assembly of the terminal male connector 2.
[0064] like Figures 11 to 12 As shown, this is one of the usage states of the plug-in terminal block 10 of this utility model. When each plug 214 is inserted into each slot 11 and the handle 221 is not rotated (pressed), each reset spring arm 223 will automatically reset and drive each locking hook 222 to engage with each locking part 12, that is, each locking tenon 226 engages with each locking groove 13, thus preventing the plug-in connection between the terminal female 1 and the terminal male 2 from becoming loose.
[0065] like Figures 13 to 14 As shown, this is another usage state of the pluggable terminal block 10 of this utility model. It uses the male terminal 2 to be plugged into the female terminal 1. When the handle 221 is rotated (pressed), it will drive each locking hook 222 to rotate at the same time, causing each reset spring arm 223 to undergo elastic deformation, so that each locking hook 222 is disengaged from each locking part 12, that is, each locking tenon 226 is disengaged from each locking groove 13, so as to achieve the effect of quickly unlocking the female terminal 1 and the male terminal 2 by pressing the handle 221.
[0066] In addition, the locking structure between the known female terminal and the male terminal is known to have sufficient locking strength. The locking structure usually occupies a volume of approximately one terminal slot space, which means that the known pluggable terminal block needs to reduce the terminal slot space to install the locking structure.
[0067] In contrast, the quick-release locking fastener 22 of this utility model is composed of a handle 221 driving multiple locking hooks 222 and multiple reset spring arms 223. The width H of each locking hook 222 and each reset spring arm 223 is 1-2mm, making it thin. However, since there are multiple locking hooks 222 and reset spring arms 223, compared with the known single locking point, the quick-release locking fastener 22 of this utility model has multiple locking points, so that the quick-release locking fastener 22 still has sufficient locking strength.
[0068] Furthermore, since the locking hooks 222 and the reset spring arms 223 are divided into multiple thin parts, the space between the multiple terminal slots 212 formed by the insulating housing 211 can be used to set up the receiving part 213 for installation. For example, in this embodiment, each locking hook 222 and each reset spring arm 223 is installed in the interval space S between two adjacent plugs 214 without affecting the original arrangement of the multiple terminal slots 212. This allows the multiple terminal slots 212 to still be arranged at equal intervals, so as to achieve the effect of not needing to reduce the number of terminal slots 212 or increase the volume of the insulating housing 211.
[0069] Therefore, this utility model, through the quick-release locking fastener 22, which is composed of a handle 221 driving multiple locking hooks 222 and multiple reset spring arms 223, can achieve the effect of quickly unlocking the terminal female seat 1 and the terminal male seat 2, and has excellent locking strength. Furthermore, each locking hook 222 and each reset spring arm 223 is installed by using the insulating shell 211 formed in the receiving part 213 between multiple terminal slots 212, so that the plug-in terminal block 10 of this utility model has the advantages of maintaining a compact size and a limited number of terminal slots 212.
[0070] In conclusion, the pluggable terminal block with quick-release fastener of this utility model can indeed achieve the intended use purpose, solve the known deficiencies, and has industrial applicability, novelty and inventiveness, fully meeting the requirements for patent application. Therefore, an application is filed in accordance with the Patent Law to protect the inventor's rights.
