DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0025] Embodiment 1, as Figures 1 to 7 As shown, an improved wiring block includes an insulating shell 1, a first wiring hole 2 and a second wiring hole 3 are opened on the top of the insulating shell 1, a first spring installation cavity 4 and a second spring installation cavity 5 are opened on the side of the insulating shell 1, a first spring 6 and a second spring 7 are installed in the first spring installation cavity 4 and the second spring installation cavity 5 respectively, the first wiring hole 2 is connected to the first spring installation cavity 4, the second wiring hole 3 is connected to the second spring installation cavity 5, a conductive sheet 8 is installed inside the insulating shell 1, and the inner side surfaces of both ends of the conductive sheet 8 are respectively against the first spring 6 and the second spring 7; in this embodiment, as shown in FIG. Figure 3 As shown, the conductive sheet 8 adopts a U-shaped conductive sheet structure, which includes a left contact sheet, a right contact sheet and a connecting sheet, and the left contact sheet and the right contact sheet are respectively arranged at the two ends of the connecting sheet to form an integrated U-shaped conductive sheet, wherein the left end of the first spring 6 is against the inner side surface of the left contact sheet, and the right end of the second spring 7 is against the inner side surface of the right contact sheet.

[0026] A cover plate 9 is provided on the side of the insulating shell 1, and the cover plate 9 is installed on the outside of the first spring clip installation cavity 4 and the second spring clip installation cavity 5; a dovetail long hook 10 and a dovetail short groove 11 are respectively provided above and below one side of the insulating shell 1; a dovetail long groove 12 and a dovetail short hook 13 are respectively provided above and below the other side of the insulating shell 1, the upper end of the dovetail long groove 12 is open, and the lower end of the dovetail short groove 11 is open; the dovetail long hook 10 matches the dovetail long groove 12, and the dovetail short groove 11 matches the dovetail short hook 13.

[0027] Working principle:

[0028] In the initial state, the right end of the first tension spring 6 abuts against the side wall of the first spring installation cavity 4, and the left end abuts against the conductive sheet 8. The left end of the second tension spring 7 abuts against the side wall of the second spring installation cavity 5, and the right end abuts against the conductive sheet 8. When wiring, the two wires are respectively inserted into the first wiring hole 2 and the second wiring hole 3, so that the ends of the wires squeeze the left end of the first tension spring 6 and the right end of the second tension spring 7 respectively, causing them to produce elastic deformation, thereby opening an opening between the first tension spring 6, the second spring 7 and the conductive sheet 8. After the wires are inserted into the opening, the elastic restoring force of the first tension spring 6 and the second spring 7 presses the wires against the left and right ends of the conductive sheet 8 respectively; so that the first wiring hole 5 and the second wiring hole 6 cooperate with each other to achieve the intercommunication function.

[0029] In this embodiment, a dovetail long hook 10 and a dovetail short slot 11 are provided on one side of the insulating shell 1; a dovetail long slot 12 and a dovetail short hook 13 are provided on the other side of the insulating shell 1; so that when multiple wiring blocks are needed to be used together, the two adjacent wiring blocks can be spliced ​​and fixed to each other by matching the dovetail long hook 10 with the dovetail long slot 12 and the dovetail short slot 11 with the dovetail short hook 13. In this embodiment, the upper end of the dovetail long slot 12 is open and the lower end of the dovetail short slot 11 is open. Therefore, when two adjacent wiring blocks are spliced, the side of one of the wiring blocks with the dovetail long hook 10 can be inserted from top to bottom into the dovetail long slot 12 on the side of the other wiring block. When inserted into the specified position, the dovetail short hook 13 at the lower end of the other wiring block is also inserted into the dovetail short slot 11; therefore, through the joint action of the dovetail long hook 10 and the dovetail short hook 13, the reliability and stability of multiple wiring blocks after splicing are effectively guaranteed.

[0030] Embodiment 2, as a further preferred embodiment of embodiment 1, a locking buckle 14 is provided on one side surface of the insulating housing 1, and a locking groove 15 is provided on the other side surface of the insulating housing 1, and the locking buckle 14 matches the locking groove 15. Therefore, when two adjacent wiring blocks are spliced ​​together, the locking buckle 14 of one wiring block can be just inserted into the locking groove 15 of the other wiring block, thereby further improving the tightness of the multiple wiring blocks after being spliced ​​together, and having a good anti-loosening function.

[0031] Embodiment 3, as a further preferred solution of embodiment 1, a hook 16 is provided at the edge of the inner side of the cover plate 9, and a card interface 17 is provided on the side walls of the first spring clip installation cavity 4 and the second spring clip installation cavity 5, and the cover plate 9 is fixed by the card hook 16 and the card interface 17.

[0032] By fixing the cover plate 9 and the insulating housing 1, the first spring 6, the second spring 7 and the conductive sheet 8 can be fixed in position, so as to effectively prevent the conductive sheet 8 from loosening or falling off. In addition, by providing a hook 16 at the edge of the cover plate 9, the hook 16 can be engaged with the card interface 17 to effectively ensure the firmness of the assembly between the cover plate 9 and the insulating housing 1, thereby effectively ensuring the anti-seismic performance of the entire wiring block.

[0033] Embodiment 4, as a further preferred solution of embodiment 1, a limiting column 18 is provided in the middle of the inner side surface of the cover plate 9, a limiting hole 19 is provided on the side surface of the insulating housing 1, the limiting hole 19 is located between the first spring clip installation cavity 4 and the second spring clip installation cavity 5, and the limiting column 18 is connected in cooperation with the limiting hole 19. When the cover plate 9 is assembled and fixed to the insulating housing 1, the limiting column 18 and the limiting hole 19 can cooperate with each other to effectively prevent the cover plate 9 from warping and deformation, thereby ensuring the neatness and aesthetics of the entire wiring block.

[0034] Embodiment 5, as a further preferred solution of embodiment 1, the upper surface of the insulating housing 1 is provided with a first button mounting hole 20 and a second button mounting hole 21, and the first button mounting hole 20 and the second button mounting hole 21 are respectively provided with a first button 22 and a second button 23, and the lower end of the first button 22 is in contact with the first tension spring 6, and the lower end of the second button 23 is in contact with the second tension spring 7. Therefore, when it is necessary to unplug the wire, the first button 22 and the second button 23 can be pressed to squeeze the left end of the first tension spring 6 and the right end of the second tension spring 7, respectively, so that the first tension spring and the second spring 7 are elastically deformed to release the wire, thereby achieving the effect of quick unplugging.

[0035] Embodiment 6, as a further preferred embodiment of embodiment 1, a test jack 24 is provided on the top of the insulating housing 1, and the test jack 24 is connected to the first spring installation cavity 4. Through the test jack 33, the test plug can be quickly inserted into the corresponding first spring installation cavity 4 to contact the first spring 6, and then test and maintenance can be performed.
