[0050] 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.

[0051] Please refer to Figures 1 to 4 As shown, this application provides a pluggable terminal block with a pressing handle, which mainly includes a female terminal block 1 and a male terminal block 2.

[0052] like Figures 3 to 4 As shown, the terminal female socket 1 is provided with one or more first locking parts 11, which are described in detail below. The terminal female socket 1 is provided with one or more slots 12, each slot 12 having a first terminal (not shown in the figure), and each first locking part 11 is a locking groove 13 opened from the inner wall of the slot 12.

[0053] like Figures 1 to 4 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 pressing handle 22.

[0054] In addition, the male connector body 21 includes an insulating housing 211 and one or more second terminals (not shown in the figure) embedded in the insulating housing 211. When the male connector 2 can be plugged into the female connector 1, the first terminal will be electrically connected to the second terminal.

[0055] Further explanation is as follows: the insulating housing 211 has a cavity 212 inside, the insulating housing 211 has an opening 213 communicating with the cavity 212 outside, and the insulating housing 211 has a pivot part 214 located in the cavity 212. The cavity 212 has an inner top wall 215 and an inner bottom wall 216 inside, and the opening 213 is opened from the inner top wall 215.

[0056] Furthermore, the pressing handle 22 is movably disposed within the cavity 212. The pressing handle 22 has a body 221, a pressing part 222, an elastic arm 223, a second locking part 224, and an extension piece 225. The pressing part 222 is formed on the top of the body 221 and exposed in the opening 213. The elastic arm 223 is a straight elastic arm 3 that extends from the body 221 at one end and is pivotally connected to the pivot part 214 at the other end. That is, the end of the elastic arm 223 is pivotally connected to the pivot part 214. The extension piece 225 extends from the body 221. The second locking part 224 is a latch 226 protruding from the extension piece 225.

[0057] In this embodiment, the pressing handle 22 is made of plastic material, the body 221 is a frame 6, the frame 6 is rectangular in shape, and the straight spring arm 3 is movably disposed in the frame 6, but is not limited thereto.

[0058] Furthermore, a pivot 4 extends from one end of the elastic arm 223 and the pivot portion 214, and a pivot hole 5 is provided on the other end of the elastic arm 223 and the pivot portion 214. The pivot 4 is pivotally connected to the pivot hole 5. The detailed description is as follows: In this embodiment, the pivot portion 214 includes a column 217 protruding upward from the inner bottom wall 216 and a pivot hole 5 opened from the column 217. The pivot hole 5 is an arc-shaped recess 218 recessed from the top of the column 217. The pivot 4 extends from the end of the elastic arm 223 and is pivotally connected to the pivot hole 5, but this is not a limitation.

[0059] like Figure 3 As shown, this is one 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 pressing part 222 is not pressed, the elastic arm 223 will automatically reset. The straight elastic arm 3 will be horizontally set between the inner top wall 215 and the inner bottom wall 216. At the same time, it will drive the body 221 to move towards the inner top wall 215, so that the pressing part 222 protrudes out of the opening 213 and drives the second locking part 224 to engage with the first locking part 11, so as to achieve the effect of locking the female terminal 1 and the male terminal 2 through the first locking part 11 and the second locking part 224, and preventing the plugging between the female terminal 1 and the male terminal 2 from loosening.

[0060] like Figure 4 As 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 pressing part 222 is pressed, it will simultaneously drive the main body 221 to move downward towards the inner bottom wall 216, causing the elastic arm 223 to elastically deform, so that the straight elastic arm 3 is set at an angle and forms an acute angle θ with the inner bottom wall 216, and drives the second locking part 224 to disengage from the first locking part 11, so as to achieve the effect of quickly unlocking the female terminal 1 and the male terminal 2 by pressing the handle 22.

[0061] Therefore, the pressing handle 22 of this application is pivotally connected to the insulating housing 211 through the end of the elastic arm 223, which can achieve the effect of quickly unlocking the terminal female 1 and the terminal male 2. Because the elastic arm 223, the pivot 4 and the pivot hole 5 have a simple structure, the plug-in terminal block 10 of this application has the advantages of quick unlocking and simplified structure.
