Description

BACKGROUND OF THE INVENTION Technical field

[0001] The present disclosure relates to the structure of terminal blocks, in particular to a plug-in terminal block with a multi-opening handle. Description of the related technique

[0002] A terminal block is a common connection component widely used in industrial communication with huge amounts of information, in industrial facilities with close connection between devices, in the power industry to improve the reliability and safety of power systems, and in more automated industrial control.

[0003] Furthermore, a plug-in terminal block has appeared on the market, comprising a female and a male terminal block that can be plugged into and unplugged. The male terminal block features an elastic hook that engages with the female terminal block, so that when the male terminal block is inserted into the female terminal block, the elastic hook firmly positions the male terminal block onto the female terminal block. Simultaneously, the male terminal block has a quick-release handle that is integrally formed with the elastic hook, allowing the user to actuate the male terminal block with their fingers to press the elastic hook and quickly detach it from the female terminal block.

[0004] The quick-release handle is integrated with the elastic hook, meaning both are made of the same metal. Although the quick-release handle and elastic hook are non-conductive, users still have concerns about the possibility of receiving an electric shock when pressing the quick-release handle with their fingers. Furthermore, if the installation space within the connector block is small, it will be difficult for the fingers to reach the front of the quick-release handle, potentially leading to users not pressing it.

[0005] In view of the aforementioned disadvantages of the related prior art, the creator of the present disclosure has made it his goal to conduct research and apply theories to overcome the aforementioned disadvantages. SUMMARY OF THE REVELATION

[0006] The present disclosure relates to a plug-in terminal block with a multi-opening handle designed such that when a pushable part is pressed or when a pluggable recess is inserted and rotated through a rod body, the elastic hook is driven to release itself from the clamping part in order to improve the ease of use of the plug-in terminal block of the present disclosure.

[0007] In one embodiment of the present disclosure, the present disclosure provides a plug-in terminal block with a multi-opening handle for use with a rod body. The plug-in terminal block comprises: a female terminal block with at least one clamping element; and a male terminal block that is detachably plugged into the female terminal block.The male connection block comprises: a male socket body; a compressible spring plate connected to the male socket body, the compressible spring plate having at least one elastic hook clamped to the at least one clamping part; and a multi-opening handle pivotally connected to and exposed from the male socket body, the inside of the multi-opening handle being provided with a pressure block configured to be relative to the compressible spring plate, the outside of the multi-opening handle being provided with a compressible part, and the top of the multi-opening handle being provided with a pluggable recess.When the squeezable part is pressed or the pluggable recess is inserted through the rod body and rotated, the pressure block is driven to push the squeezable spring plate to release the at least one elastic hook from the at least one clamping part.

[0008] Based on the foregoing, a quick-release function can be implemented in two ways: for example, by pressing the pushable part on the outside of the multi-opening handle and by inserting the rod body of the hand tool into the pluggable recess on the top of the multi-opening handle. This allows for quick release even if the pushable part is blocked, as the pluggable recess remains accessible. Even if the pluggable recess is blocked, users are still able to perform the quick-release function through the pluggable recess, thus improving the usability of the plug-in terminal block of this disclosure.

DETAILED DESCRIPTION

[0009] The technical content of this disclosure becomes apparent with the detailed description of embodiments, which are accompanied by the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be regarded as illustrative and not as limiting.

[0010] With reference to the Fig. 1 to Fig. 5. For a plug-in terminal block with a multi-opening handle according to the present disclosure, the plug-in terminal block with a multi-opening handle is used for a rod body 100 of a hand tool. The plug-in terminal block 10 mainly comprises a female terminal block 1 and a male terminal block 2, and the plug-in terminal block 10 provides a wiring platform for connecting terminals and wires.

[0011] As in the Fig. 2 to Fig. As shown in Figure 5, the female terminal block 1 of this embodiment is provided with a plurality of terminal elements 11. In detail, the female terminal block 1 comprises a female socket body 12 and a plurality of first terminals 13. The female socket body 12 is made of an insulating material such as plastic. The female socket body 12 is provided with a plurality of slots 121. Each first terminal 13 is received in each slot 121. Each terminal element 11 is formed on the inner wall of each slot 121. Each terminal element 11 is a terminal 111 formed on the inner wall of each slot 121. However, the number of terminal elements 11, slots 121, and first terminals 13 can also be one. The terminal element 11 is not limited to the terminal 111; it can also be a groove or a block. The present disclosure is not limited to this.

[0012] As in the Fig. 1 to Fig. As shown in Figure 5, the male terminal block 2 is detachably inserted into the female terminal block 1; that is, the male terminal block 2 is inserted into or detached from the female terminal block 1. The male terminal block 2 comprises a male socket body 21, a compressible spring plate 22, a multi-opening handle 23, a plurality of secondary terminals 24, and a plurality of wire compression spring plates 25. The male socket body 21 is made of an insulating material such as plastic. The compressible spring plate 22 of this embodiment is made of a metallic material, but the present disclosure is not limited thereto.

[0013] The upper section of the front side wall of the male socket body 21 is provided with a snap groove 213 and a pivot hole 214, located on the upper and lower parts, respectively. The male socket body 21 extends downwards with a plurality of plugs 216. The upper surface of the male socket body 21 is provided with a plurality of wire sockets 217, each passing through each plug 216. Every second terminal 24 and each wire clamping plate 25 are received in each wire socket 217. The wire is inserted into the wire socket 217 and clamped by the wire clamping plate 25 to be electrically connected to the second terminal 24. However, the quantities of the second terminal 24, the wire clamping plate 25, the positioning groove 212, the plug 216, and the wire socket 217 are all one, and the present disclosure is not limited thereto.

[0014] Furthermore, the compressible spring plate 22 is connected to the male socket body 21, the compressible spring plate 22 having a plurality of elastic hooks 221, each elastic hook 221 engaging with each clamping part 11, such that the male terminal block 2 engages with the clamping part 11 via the elastic hook 221 and is securely locked to the female terminal block 1. In this embodiment, each elastic hook 221 engages with and is free from each terminal 111, allowing users to push the elastic hook 221 through the terminal 111 to disconnect it.

[0015] Further description is given below. The compressible spring plate 22 comprises a compressed section 222 and a plurality of longitudinal arms 223 extending downwards from the compressed section 222, each longitudinal arm 223 being arranged at the front of each plug 216, and each plug 216 being inserted into the plug slot 121, such that each plug 216, each longitudinal arm 223, and each elastic hook 221 are inserted into each plug slot 121. At this point, the first terminal 13 and the second terminal 24 are electrically connected, and the elastic hook 221 is extended and formed by the longitudinal arm 223. However, the quantity of the elastic hook 221 and the longitudinal arm 223 is still one, and the present disclosure is not limited to this.

[0016] Furthermore, the multi-opening handle 23 is made of a plastic material to achieve the insulating effect. The multi-opening handle 23 is pivotally connected to the male bushing body 21 and is exposed to the outside of the male bushing body 21. The multi-opening handle 23 has a pressure block 231, which is arranged on the inside opposite the compressible spring plate 22, a compressible part 232 on the outside, and a pluggable recess 233 on the top. The pressure block 231 is formed by extending from the inner side wall of the compressible part 232 in the direction near the compressed section 222. The pressure block 231 is arranged at the front of the compressed section 222.

[0017] A gap S is formed between the pressed section 222 and the longitudinal arm 223 and the lower section of the front side wall of the male bushing body 21. When the pressed section 222 is pushed by the pressure block 231, the pressed section 222 and the longitudinal arm 223 are elastically deformed and retracted into the gap S. When no force is applied to the pressed section 222, the pressed section 222 returns to its original position relative to the elastic hook 221 to engage with the clamping part 11.

[0018] In this embodiment, each longitudinal arm 223 has an L-shaped pin 224 extending from one end of the pressed section 222. The L-shaped pin 224 is firmly inserted into the positioning groove 212, so that the compressible spring plate 22 is connected to the lower section of the front side wall of the male bushing body 21. The gap S is formed between the pressed section 222 and the longitudinal arm 223 and the inner wall of the recess 211, so that the pressed section 222 and the longitudinal arm 223 can be retracted into the recess 211 when they are retracted and deformed.

[0019] Furthermore, the multi-opening handle 23 of the present embodiment is made of an elastic plastic material, but the present disclosure is not limited thereto. The multi-opening handle 23 has a pin 234 and a pivot point 235, which are arranged on the top and bottom surfaces, respectively. The pin 234 engages with the snap groove 213, and the pivot point 235 is pivotally connected to the pivot hole 214. The pivot point 235 is arranged between the pin 234 and the pressure block 231, so that the multi-opening handle 23 is installed on the upper section of the front side wall of the male bushing body 21.The multi-opening handle 23 is limited by the pin 234 and the snap groove 213, such that the pivot point 235 is slightly pivoted relative to the pivot hole 214. Therefore, in the present embodiment, the multi-opening handle 23 does not drive the pressure block 231 to press the compressible spring plate 22 through a large pivot angle. The pluggable recess 233 is elastically deformed primarily by the elastic plastic material itself, so that the compressible part 232 retracts and deforms when pressed, thereby driving the pressure block 231 to press the compressible spring plate 22. When the pluggable recess 233 is inserted into the rod body 100 of the hand tool and rotated, the compressible part 232 retracts and deforms, thereby driving the pressure block 231 to press the compressible spring plate 22.

[0020] As in the Fig. 4 and Fig. As shown in Figure 5, the plug-in terminal block 10 of the present disclosure is in use. When the pushable part 232 is pressed, or the pluggable recess 233 is inserted and rotated through the rod body 100 like a hand tool, the multi-opening handle 23 drives the pressure block 231 to press the pushable spring plate 22. When the pushable spring plate 22 is pressed by the pressure block 231, the elastic hook 221 is driven to separate from the clamping part 11, and the male terminal block 2 is quickly separated from the female terminal block 1, so that the plug-in terminal block 10 is able to achieve the quick-release function by means of the multi-opening handle 23.

[0021] In this way, the multi-opening handle 23 is opened in two ways: the outer side is opened by pressing the pushable part 232, and the top of the multi-opening handle 23 is opened by inserting the rod body 100 of the hand tool into the pluggable recess 233, thus narrowing the installation space of the plug-in terminal block 10. When the pushable part 232 is covered, the user can still perform the quick-release function through the pluggable recess 233, and vice versa, thus improving the usability of the plug-in terminal block 10 of the present disclosure.

[0022] Furthermore, the multi-opening handle 23 is made of a plastic material to achieve the insulating effect, so that users no longer have any concerns about a possible electric shock when touching the multi-opening handle 23, which further increases the safety of the plug terminal block 10 of the present disclosure.

[0023] With reference to the Fig. 6 to Fig. 9 for the plug-in terminal block 10 according to another embodiment of the present disclosure are the ones in the Fig. 6 to Fig. The embodiments shown in section 9 are essentially the same as those shown in the Fig. 1 to Fig. 5 illustrated embodiments. The difference between the embodiments of the Fig. 6 to Fig. 9 and the embodiments of the Fig. 1 to Fig. 5 consists in an L-shaped pin 224' extending from one end of the longitudinal arm 223 away from the pressed section 222. The L-shaped pin 224' extends integrally from the lower edge of the front side wall of the male bushing body 21. That is, the compressible spring plate 22 is made of an insulating material such as plastic, like the male bushing body 21, and the quantity of the elastic hook 221, the longitudinal arm 223, and the L-shaped pin 224' is one in this embodiment. In this way, the same functions and effects are achieved as in the embodiments of Fig. 1 to Fig. 5 reached.

[0024] The above embodiments are only preferred embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Therefore, it is understood that all variations of equivalent techniques that fall within the spirit and scope of the appended claims should likewise be included within the scope of the present disclosure.
