Description

Technical Field

[0001] This application relates to a terminal block structure, and more particularly to a plug-in terminal block with a quick-release locking mechanism. 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. At the same time, in order to prevent the plugging and unplugging of female and male terminal blocks from being easily loosened, a locking structure is provided between female and male terminal blocks.

[0004] However, the aforementioned locking structure is often installed between multiple terminal groups, requiring the pluggable terminal block to reduce the space of one terminal group and one cable slot to accommodate the locking structure. Therefore, the applicant's research focus is on how to enable the locking structure of the pluggable terminal block to have quick-release and quick-assembly functions without reducing the number of terminal groups and cable slots.

[0005] In view of this, the applicant has devoted himself to studying the aforementioned prior art and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the target of the applicant's improvement. Utility Model Content

[0006] This application provides a pluggable terminal block with a quick-release locking mechanism. The quick-release locking mechanism is installed on the outer wall of the terminal plug. By turning the handle, the push arm can be driven to push the elastic piece away from the terminal slot, so that the first locking part and the second locking part are disengaged. This achieves the advantages of the pluggable terminal block of this application, which is quick to unlock and does not occupy the installation space of the cable slot.

[0007] In this application embodiment, a pluggable terminal block with a quick-release locking member is provided, including: a female terminal base having a terminal slot, an elastic piece disposed on one side of the terminal slot, and a first locking portion formed on the elastic piece; and a male terminal base detachably plugged into the female terminal base, the male terminal base including: a male base body including an insulating shell, the insulating shell having a terminal plug that is plugged into the terminal slot; and a quick-release locking member installed on the outer wall of the terminal plug and inserted into the terminal slot along with the terminal plug, the quick-release locking member having a handle formed at one end and exposed outside the terminal slot, at least one push arm formed at the other end and disposed corresponding to the elastic piece, and a second locking portion disposed between the handle and the push arm and engaging with the first locking portion; wherein, pulling the handle can drive the push arm to push the elastic piece away from the terminal slot, so as to disengage the first locking portion from the second locking portion.

[0008] In one embodiment, the end of the insulating housing away from the terminal plug has a cable slot, and when the terminal plug is inserted into the terminal slot, the handle is located between the terminal socket and the cable slot.

[0009] In one embodiment, the thickness of the cable slot is greater than the thickness of the terminal plug, so that a recessed area is formed between the terminal socket and the cable slot to provide a retractable handle.

[0010] In one embodiment, there are two push arms, the quick-release locking element has a main body, a second locking part is formed on the main body, and the two push arms are arranged on the outside of the main body.

[0011] In one embodiment, the first locking part is a slot formed in the inner wall of the elastic sheet, and the second locking part is an oblique locking tenon that protrudes from the main body and gradually decreases in thickness toward the terminal slot, and the oblique locking tenon engages with the slot.

[0012] In one embodiment, the handle extends from the end of the body and the two push arms away from the terminal female and forms an acute angle with the body and the two push arms.

[0013] In one embodiment, the terminal plug is inserted into the terminal slot along the insertion direction, and the outer wall of the terminal plug has two limiting ribs that are arranged along the insertion direction. A gap is formed between the main body and the two push arms, and each limiting rib is embedded in the gap.

[0014] In one embodiment, the outer wall of the terminal plug protrudes with a first stop block and a second stop block spaced apart along the insertion direction. The end of the main body away from the handle is provided with a notch. The first stop block is embedded in the notch and stops the main body. When the terminal plug is inserted into the terminal slot, the second stop block stops the terminal socket.

[0015] In one embodiment, the handle has a hollow opening that connects to it at a certain distance, and a second stop block extends integrally with a limiting rib and passes through the hollow opening.

[0016] In one embodiment, the female terminal is provided with two grooves communicating with the terminal slot at one end adjacent to the male terminal, and an elastic sheet is formed between the two grooves.

[0017] Based on the above, the quick-release locking device of this application is installed on the outer wall of the terminal plug, so it does not affect the original cable slot seat setting space, and therefore does not need to reduce the number of multiple cable slots, so that the quick-release locking device of this application has the advantage of not occupying the setting space of the cable slot.

[0055] The detailed description and technical content of this application 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 application.

[0056] Please refer to Figures 1 to 5 As shown, this application provides a pluggable terminal block with a quick-release locking mechanism. This pluggable terminal block 10 mainly includes a female terminal block 1 and a male terminal block 2.

[0057] like Figures 1 to 5 As shown, the terminal socket 1 has a terminal slot 11, an elastic piece 12 disposed on one side of the terminal slot 11, and a first locking part 13 formed on the elastic piece 12. A plurality of first terminals 15 are installed in the terminal slot 11.

[0058] The following is a detailed description: In this embodiment, the terminal female seat 1 is provided with two grooves 14 that connect to the terminal slot 11 at one end adjacent to the terminal male seat 2. The elastic sheet 12 is formed between the two grooves 14, so that the elastic sheet 12 can be elastically deformed under force. The first locking part 13 is a slot 131 opened from the inner wall of the elastic sheet 12, but it is not limited thereto.

[0059] like Figures 1 to 5 As shown, the male terminal 2 can be detachably plugged into the female terminal 1, that is, the male terminal 2 can be plugged 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 terminal body 21 and a quick-release locking member 22. The male terminal body 21 includes an insulating housing 211 and a plurality of second terminals 217. The insulating housing 211 has a terminal plug 212 that is plugged into the terminal slot 11. The plurality of second terminals 217 are accommodated in the terminal plug 212 and can be electrically connected to a plurality of first terminals 15.

[0060] Further explanation is as follows: The end of the insulating housing 211 away from the terminal plug 212 has a cable slot seat 213. The end of the cable slot seat 213 away from the terminal plug 212 is provided with multiple cable slots 2131. Each cable slot 2131 provides a cable (not shown in the figure) for insertion at one end and accommodates a second terminal 217 at the other end, so that when the cable is inserted into the cable slot 2131, it will be electrically connected to the second terminal 217, and then electrically connected to the first terminal 15 through the second terminal 217.

[0061] In addition, the quick-release locking member 22 is installed on the outer wall of the terminal plug 212 and is inserted into the terminal slot 11 along with the terminal plug 212. The quick-release locking member 22 has a handle 221 formed at one end, one or more push arms 222 formed at the other end, and a second locking part 223 disposed between the handle 221 and the push arms 222 and engaged with the first locking part 13. The push arms 222 are configured corresponding to the elastic piece 12, and the second locking part 223 engages with the first locking part 13.

[0062] When the terminal plug 212 is inserted into the terminal slot 11, the handle 221 is exposed outside the terminal slot 11 and located between the terminal female seat 1 and the cable slot seat 213. In this embodiment, the thickness H1 of the cable slot seat 213 is greater than the thickness H2 of the terminal plug 212, so that a recessed area for storing the handle 221 is formed between the terminal female seat 1 and the cable slot seat 213.

[0063] Furthermore, in this embodiment, there are two push arms 222, and each push arm 222 has a protrusion 2221 at its end. The quick-release locking fastener 22 has a main body 220, and a second locking part 223 is formed on the main body 220. The two push arms 222 are arranged on the outside of the main body 220. The second locking part 223 is an oblique tenon 224 that protrudes from the main body 220 and gradually decreases in thickness toward the terminal slot 11. The oblique tenon 224 engages with the slot 131, but this is not a limitation.

[0064] Furthermore, the terminal plug 212 is inserted into the terminal slot 11 along the insertion direction D. In this embodiment, the outer wall of the terminal plug 212 protrudes with two limiting ribs 214 arranged along the insertion direction D. A gap S is formed between the main body 220 and the two push arms 222. Each limiting rib 214 is embedded in each gap S, so that the quick-release locking member 22 is limited in the lateral direction by the limiting ribs 214.

[0065] Furthermore, the outer wall of the terminal plug 212 protrudes with a first stop block 215 and a second stop block 216 spaced apart along the insertion direction D. The end of the main body 220 away from the handle 221 is provided with a notch 2201. The first stop block 215 is embedded in the notch 2201 and stops the main body 220, so that the quick-release locking member 22 is limited in the longitudinal direction by the first stop block 215. When the terminal plug 212 is inserted into the terminal slot 11, the second stop block 216 stops the terminal female seat 1.

[0066] Furthermore, in this embodiment, the handle 221 extends from the end of the main body 220 and the two push arms 222 away from the terminal female seat 1 and forms an acute angle θ between the main body 220 and the two push arms 222. The handle 221 is provided with a hollow opening 2211 that connects to its distance S. The second stop block 216 and its limiting rib 214 extend integrally and pass through the hollow opening 2211, so that the handle 221 will not be interfered with by the second stop block 216 when it is turned.

[0067] like Figures 3 to 4 As shown, this is one usage state of the pluggable terminal block 10 of this application. When the terminal plug 212 is inserted into the terminal slot 11, the oblique locking tenon 224 will gradually push the elastic piece 12 outward and elastically deform away from the terminal slot 11 due to its oblique surface relationship, until the oblique locking tenon 224 enters the slot 131. The elastic piece 12 will then automatically reset and drive the oblique locking tenon 224 to engage with the slot 131, so that the terminal female 1 and the terminal male 2 are locked together by the quick-release locking fastener 22, so as to prevent the plugging and unplugging of the terminal female 1 and the terminal male 2 from becoming loose.

[0068] like Figure 5As shown, this is another usage state of the pluggable terminal block 10 of this application. It uses the male terminal 2 to be plugged into the female terminal 1. When the handle 221 is turned, turning the handle 221 will drive the protrusion 2221 of the push arm 222 to push the elastic piece 12 away from the terminal slot 11, thereby causing the first locking part 13 to disengage from the second locking part 223, so as to achieve the effect of quickly unlocking the female terminal 1 and the male terminal 2 by turning the handle 221.

[0069] In addition, conventional locking structures are often installed between multiple terminal groups, which means that pluggable terminal blocks need to reduce the space of one terminal group and one cable slot to install the locking structure. Therefore, conventional pluggable terminal blocks need to reduce the space of one cable slot to install the locking structure.

[0070] In contrast, the quick-release locking fastener 22 of this application is installed on the outer wall of the terminal plug 212, so it does not affect the original cable slot seat 213 setting space, and therefore does not need to reduce the number of multiple cable slots 2131. This gives the quick-release locking fastener 22 the advantage of not occupying the setting space of the cable slot 2131.

[0071] Furthermore, the quick-release locking fastener 22 of this application is only limited laterally by the limiting rib 214, limited longitudinally by the first stop block 215, and locked by the first locking part 13 and the second locking part 223. This allows the quick-release locking fastener 22 to be securely installed between the terminal female seat 1 and the terminal male seat 2, without the need for additional pivot structure design as in conventional methods. This achieves the characteristic of simplified structure of the plug-in terminal block 10 of this application.
