Description

Technical Field

[0001] This utility model relates to a terminal block structure, and more particularly to a pluggable terminal block with a multi-opening handle. 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 addition, a pluggable terminal block has appeared on the market, which includes a pluggable female terminal and a male terminal. The male terminal has a flexible hook that can engage with the female terminal, so that when the male terminal is plugged into the female terminal, the male terminal can be firmly positioned on the female terminal by the flexible hook. At the same time, the male terminal has a quick-release handle integrally formed with the flexible hook, so that the male terminal can be pressed with a finger to drive the flexible hook to quickly disengage from the female terminal.

[0004] However, since the quick-release handle uses an integrated connection to drive the elastic hook, both the quick-release handle and the elastic hook are made of metal. Although the quick-release handle and the elastic hook are not conductive, users may still worry that pressing the quick-release handle with their fingers could cause an electric shock. Also, if the installation space of the plug-in terminal block is small, it may also prevent fingers from reaching the front of the quick-release handle, causing the problem that the fingers cannot press the quick-release handle.

[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 utility model provides a pluggable terminal block with a multi-opening handle. When the pressable part is pressed or the insertable recess is inserted into the rod and moved, the elastic hook will disengage from the locking part, thereby improving the ease of use of the pluggable terminal block of this utility model.

[0007] In this embodiment of the present invention, a pluggable terminal block with a multi-opening handle is provided for a rod body. The pluggable terminal block includes: a female terminal with at least one locking portion; and a male terminal that can be detachably plugged into the female terminal. The male terminal includes: a male terminal body; a pushable spring connected to the male terminal body, the pushable spring having at least one elastic hook that engages with the at least one locking portion; and a multi-opening handle pivotally connected to the male terminal body and exposed outside the male terminal body. The multi-opening handle has a push block on its inner side that is opposite to the pushable spring, a pressable portion on its outer side, and an insertable recess on its top side. When the pressable portion is pressed, or when the insertable recess is inserted into and moved by the rod body, the push block will push the pushable spring, thereby disengaging the at least one elastic hook from the at least one locking portion.

[0008] Based on the above, since the multi-opening handle can be opened in two ways—by pressing the pressable part on the outside and by inserting a hand tool into the insertable recess on the top side—the installation space of the plug-in terminal block is small. Even when the pressable part is covered, the user can still perform the quick-release function through the insertable recess. This improves the ease of use of the plug-in terminal block of this utility model.

[0009] Based on the above, since the multi-opening handle is made of plastic and thus achieves insulation, users will not have any concerns about electric shock when touching the multi-opening handle, further enhancing the safety of using the plug-in terminal block of this utility model.

[0050] 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.

[0051] Please refer to Figures 1 to 5 As shown, this utility model provides a pluggable terminal block with a multi-opening handle for use in, for example, the handle 100 of a hand tool. This pluggable terminal block 10 mainly includes a female terminal 1 and a male terminal 2. The pluggable terminal block 10 provides a wiring platform for connecting terminals and wires.

[0052] like Figures 2 to 5 As shown, the terminal female socket 1 of this embodiment is provided with a plurality of locking parts 11. The terminal female socket 1 includes a female socket body 12 and a plurality of first terminals 13. The female socket body 12 is made of insulating material such as plastic. The female socket body 12 is provided with a plurality of slots 121. Each first terminal 13 is accommodated in each slot 121. Each locking part 11 is formed on the inner wall of each slot 121. Each locking part 11 is a through opening 111 opened from the inner wall of each slot 121. However, the number of locking parts 11, slots 121 and first terminals 13 may also be one. Moreover, the locking part 11 is not limited to the through opening 111. The locking part 11 may also be a groove or a locking block, which is not limited to this embodiment.

[0053] like Figures 1 to 5 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 or detached from the female terminal 1. The male terminal 2 includes a male body 21, a pushable spring 22, a multi-opening handle 23, multiple second terminals 24 and multiple wire clamping springs 25. The male body 21 is made of insulating materials such as plastic. In this embodiment, the pushable spring 22 is made of metal, but this is not a limitation.

[0054] The lower section of the front side wall of the male seat body 21 is provided with a recess 211 and multiple positioning grooves 212 arranged vertically. The upper section of the front side wall of the male seat body 21 is provided with a locking groove 213 and a pivot hole 214 arranged vertically. Multiple plugs 216 extend downward from the male seat body 21. Multiple wire sockets 217 are opened on the top of the male seat body 21, which pass through each plug 216 respectively. Each second terminal 24 and each wire clamping spring 25 are accommodated in each wire socket 217. The wire can be inserted into the wire socket 217 and clamped by the wire clamping spring 25 to be electrically connected to the second terminal 24. However, the number of second terminals 24, wire clamping springs 25, positioning grooves 212, plugs 216 and wire sockets 217 can also be one, and is not limited to this embodiment.

[0055] Additionally, a pushable spring 22 is connected to the male connector body 21. The pushable spring 22 has multiple elastic hooks 221, each of which engages with a locking part 11, so that the male connector 2 is stably locked onto the female connector 1 by the elastic hooks 221 engaging with the locking parts 11. In this embodiment, each elastic hook 221 is engaged and exposed in each opening 111, allowing the user to push the elastic hook 221 out of the opening 111.

[0056] Further explanation is as follows: The pushable spring 22 has a pushed section 222 and a plurality of longitudinal arms 223 extending downward from the pushed section 222. Each longitudinal arm 223 is disposed on the front side of each plug 216 and follows each plug 216 into the slot 121, so that each plug 216, each longitudinal arm 223 and each elastic hook 221 are inserted into each slot 121 together. At this time, the first terminal 13 and the second terminal 24 are electrically connected. The elastic hook 221 extends from the longitudinal arm 223. However, the number of elastic hooks 221 and longitudinal arms 223 can also be one, and is not limited to this embodiment.

[0057] Furthermore, the multi-opening handle 23 is made of plastic to achieve insulation. The multi-opening handle 23 is pivotally connected to the male seat body 21 and exposed on the outside of the male seat body 21. The multi-opening handle 23 has a push block 231 on the inner side that is opposite to the pushable spring 22, a pressable part 232 on the outer side, and an insertable recess 233 on the top side. The push block 231 is formed by extending from the inner wall of the pressable part 232 toward the direction close to the pushed section 222. The push block 231 is disposed on the front side of the pushed section 222.

[0058] Among them, a gap S is formed between the pushed section 222 and the longitudinal arm 223 and the lower section of the front side wall of the male seat body 21. When the pushed section 222 is pushed by the pushed block 231, the pushed section 222 and the longitudinal arm 223 can elastically deform and retract into the gap S. When the pushed section 222 is not under force, the pushed section 222 will return to the elastic hook 221 and engage with the locking part 11.

[0059] Furthermore, in this embodiment, each longitudinal arm 223 extends an L-shaped pin 224 from the end away from the pushed section 222. The L-shaped pin 224 is tightly inserted into the positioning groove 212 so that the pushable spring 22 is connected to the lower section of the front side wall of the male seat body 21. The spacing S is formed between the pushed section 222 and the longitudinal arm 223 and the inner wall of the recess 211, so that when the pushed section 222 and the longitudinal arm 223 are retracted and deformed, they can be retracted into the recess 211.

[0060] Furthermore, the multi-opening handle 23 in this embodiment is made of elastic plastic material, but this is not a limitation. The multi-opening handle 23 extends with a latch 234 and a pivot 235 arranged at the top and bottom. The latch 234 engages with the groove 213, and the pivot 235 is pivotally connected to the pivot hole 214. The pivot 235 is located between the latch 234 and the push block 231, so that the multi-opening handle 23 is installed on the upper part of the front side wall of the male seat body 21. The multi-opening handle 23 is limited by the latch 234 and the groove 213, so the pivot 235 can only be slightly opposite. The pivot hole 214 pivots, so that the multi-opening handle 23 in this embodiment does not drive the push block 231 to push the pushable spring 22 by a large pivot angle. The multi-opening handle 23 mainly uses its own elastic plastic material to deform elastically under force, so that when the pressable part 232 is pressed, it will shrink and deform inward, thereby driving the push block 231 to push the pushable spring 22. When the insertable recess 233 is inserted into, for example, the handle 100 of a hand tool and is turned, it will pull the pressable part 232 to shrink and deform inward, thereby driving the push block 231 to push the pushable spring 22.

[0061] like Figures 4 to 5 In the usage state of the pluggable terminal block 10 of this utility model, when the pressable part 232 is pressed, or when the insertable recess 233 is inserted and turned by, for example, the handle 100 of a hand tool, the multi-open handle 23 will drive the push block 231 to push the pushable spring 22. When the pushable spring 22 is pushed by the push block 231, it will drive the elastic hook 221 to disengage from the locking part 11, and the male terminal 2 can be quickly disengaged from the female terminal 1, so that the pluggable terminal block 10 can achieve the quick-release function through the multi-open handle 23.

[0062] Therefore, since the multi-opening handle 23 can be opened by pressing the pressable part 232 on the outside and by inserting the handle 23 top side into the insertable recess 233 through, for example, the handle 100 of a hand tool, the installation space of the plug-in terminal block 10 is small. Even when the pressable part 232 is covered, the user can still perform the quick-release function through the insertable recess 233. Even when the insertable recess 233 is covered, the user can still perform the quick-release function through the pressable part 232, thereby improving the ease of use of the plug-in terminal block 10 of this utility model.

[0063] In addition, since the multi-opening handle 23 is made of plastic, it achieves insulation, so users will not have any concerns about electric shock when touching the multi-opening handle 23, which further enhances the safety of using the plug-in terminal block 10 of this utility model.

[0064] like Figures 6 to 9 The image shows another embodiment of the pluggable terminal block 10 of this utility model. Figures 6 to 9 Implementation examples and Figures 1 to 5 The embodiments are largely the same. Figures 6 to 9 Implementation examples and Figures 1 to 5 The difference in this embodiment lies in that an L-shaped pin 224' extends from the end of the longitudinal arm 223 away from the pushed section 222. The L-shaped pin 224' extends integrally from the bottom edge of the front side wall of the male seat body 21. The push-press spring 22, like the male seat body 21, is made of insulating material such as plastic. Furthermore, in this embodiment, the number of elastic hooks 221, longitudinal arms 223, and L-shaped pins 224' is one. This achieves the same effect as... Figures 1 to 5 The functions and effects of the embodiments.

[0065] In conclusion, the pluggable terminal block with multi-opening handle of this utility model can indeed achieve the intended use purpose and solve the known deficiencies, fully meeting the requirements for patent application. Therefore, an application is filed in accordance with the Patent Law to protect the applicant's rights.
