The wiring terminals are easily affected by dust, leading to problems such as poor contact or short circuit, and cannot meet the requirements of modern industry for the wiring terminals to be efficient, stable, and safe. Therefore, improvement is needed. Utility Model Content

[0047] The following will describe in detail some embodiments of this application with reference to the accompanying drawings. Without conflict, those skilled in the art can combine and combine the different embodiments or examples and the features of different embodiments or examples represented in this application.

[0048] An embodiment of this application discloses a terminal block. Refer to Figures 1 to 3 , the terminal block includes a housing 1, a conductive block 2, a mounting block 3 and a dust cover 4. The housing 1 is open, the conductive block 2 is detachably mounted on the housing 1, and the mounting block 3 is connected to the conductive block 2; the dust cover 4 is detachably connected to the housing 1 and is used to cover the upper part of the mounting block 3. The design of the dust cover 4 can play a certain blocking role on the conductive block 2, effectively preventing dust and other sundries from entering the interior of the terminal block and improving the dust-proof performance of the terminal block.

[0049] The dust cover 4 can be installed on the housing 1 by means of plugging, clamping or bolt locking. In this embodiment, the clamping method is adopted. When dust accumulates on the surface of the dust cover 4, the staff can detach the dust cover 4 from the housing 1 and then clean it. After the dust cover 4 is damaged, it can also be disassembled and replaced to improve the practicability. In some embodiments, the dust cover 4 is made of a transparent material, and the transparent material includes but is not limited to acrylic plates, glass, PC, etc. The dust cover 4 made of a transparent material can transmit light, facilitating the staff to observe the conductive block 2.

[0050] Refer to Figure 4 and Figure 5, Specifically, a receiving cavity 5 is formed on the outer shell 1 for installing the conductive block 2. A relief hole 6 is formed on the outer shell 1, which communicates with the receiving cavity 5 and is used for the conductive block 2 to enter the receiving cavity 5. A limiting block 7 is fixedly connected to the outer shell 1, and the limiting block 7 is located in the receiving cavity 5. The thickness of the limiting block 7 gradually increases along the insertion direction of the conductive block 2. A limiting card slot 8 is formed on the side wall of the conductive block 2. When the limiting block 7 is completely inserted into the limiting card slot 8, the conductive block 2 stops moving and is fixed on the outer shell 1.

[0051] Refer to Figure 6 and Figure 7 , two pairs of sides of the conductive block 2 are open, and the mounting block 3 is snap-fitted into the conductive block 2. In this embodiment, a plurality of limiting blocks 7 are provided on the outer shell 1, and each limiting block 7 is located in the receiving cavity 5; the thickness of the limiting block 7 gradually increases along the insertion direction of the conductive block 2, so that an inclined guiding surface and a horizontal surface are formed on the limiting block 7, and the inclined guiding surface and the horizontal surface are arranged in sequence along the insertion direction of the mounting block 3. A convex block 13 is fixedly connected to the outer surface of the mounting block 3. When the mounting block 3 is gradually inserted into the receiving cavity 5, the convex block 13 moves along the inclined guiding surface of the limiting block 7 and finally is stuck on the horizontal surface of the limiting block 7.

[0052] When it is necessary to install the conductive block 2 on the outer shell 1, the user can apply an external force to the conductive block 2 so that the conductive block 2 is gradually inserted into the receiving cavity 5 until the limiting block 7 is exactly inserted into the limiting card slot 8. At this time, the conductive block 2 cannot move any further, thus completing the connection between the conductive block 2 and the outer shell 1. Through the unique quick-installation structure, the quick positioning and fixing of the conductive block 2 are realized.

[0053] Meanwhile, during the process that the conductive block 2 drives the mounting block 3 to be gradually inserted into the receiving cavity 5, the outer surface of the mounting block 3 will be in contact with the inner wall of the receiving cavity 5. The mounting block 3 overcomes the frictional force and moves along the inclined guiding surface of the limiting block 7, and finally the convex block 13 on the mounting block 3 is snap-fitted on the horizontal surface of the limiting block 7. With the mutual cooperation of the limiting block 7 and the convex block 13, the fixing of the mounting block 3 is realized and the movement of the mounting block 3 is restricted.

[0054] Among them, a plurality of card strips 14 are also connected to the outer shell 1. The length direction of the card strips 14 is parallel to the length direction of the conductive block 2, and the card strips 14 are spaced apart and distributed in the receiving cavity 5. After the conductive block 2 and the mounting block 3 are inserted into the receiving cavity 5, the two will be squeezed by the card strips 14, and the static frictional force in contact is increased, thereby improving the stability of the conductive block 2 and the mounting block 3. In some embodiments, a limiting rib 12 is also fixedly connected to the outer shell 1. The limiting rib 12 is located in the receiving cavity 5. A limiting groove 15 is formed on the conductive block 2. When the conductive block 2 is inserted into the receiving cavity 5, the limiting rib 12 is snap-fitted into the limiting groove 15, and the connection stability between the conductive block 2 and the outer shell 1 is further improved through the frictional force.

[0055] In this embodiment, in combination with Figure 8 and Figure 9 , the conductive block 2 includes a wiring input end 9 and a plurality of wiring output ends 10, and each wiring output end 10 is electrically connected to the wiring input end 9. In this embodiment, the number of the wiring output ends 10 is two, the two wiring output ends 10 are located on the same side and are close to the dust cover 4. One wiring input end 9 corresponds to a plurality of wiring output ends 10 to improve the connection efficiency.

[0056] In addition, a fastening assembly 11 is also connected to the conductive block 2. The fastening assembly 11 is used to fix an external wire on the conductive block 2, thereby completing the connection between the conductive block 2 and the wire. The fastening assembly 11 includes a fastener 111 and a locking member 112. The locking member 112 is a nut and is connected to the mounting block 3; the fastener 111 is a fastening bolt. The fastening bolt passes through the conductive block 2 and is screwed onto the locking member 112. As shown in the figure, the number of the fastening assemblies 11 in this embodiment is three. During installation, first sleuth the wire on the fastener 111, and then lock the fastener 111 on the locking member 112 to fix the wire.

[0057] The implementation principle of a wiring terminal in an embodiment of this application is as follows: The mounting block 3 is installed inside the conductive block 2. The mounting block 3 plays a role in shielding the inner surface of the conductive block 2, reducing the possibility of dust contacting the mounting block 3. The conductive block 2 is snapped into the receiving cavity 5 along the relief hole 6, realizing the quick fixation of the conductive block 2 on the housing 1. Finally, the dust cover 4 is snap-connected to the housing 1 to further shield the conductive block 2, effectively preventing dust and other sundries from invading the inside of the wiring terminal and improving the dust-proof performance of the wiring terminal.

[0058] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
