Specific embodiments

[0026] As Figures 1 - 7 shown, in the first embodiment of the present utility model, a wiring terminal includes a base 1. An installation groove 2 is provided inside the base 1. It also includes a wire - pressing plate 5. The front side of the installation groove 2 is open. A wiring frame is provided inside the installation groove 2. A wire - passing hole 31 is provided on the front side of the wiring frame. The upper surface of the wiring frame is connected with a screw 4 by thread. The wire - pressing plate 5 includes a first plate body 51, a second plate body 52, and a connecting plate 53 connecting the first plate body 51 and the second plate body 52. The first plate body 51 is provided with a first through - hole 511. The first plate body 51 is located on the wiring frame and is sleeved on the screw 4 through the first through - hole 511. The second plate body 52 is located at the lower end of the screw 4. The base 1 is provided with a partition board 18, and the partition board 18 divides the base 1 into several installation grooves 2. The bottom surface of the wiring frame is provided with pins 34, and the base 1 is provided with a third through - hole 11 for the pins 34 to pass through. When wiring, the wire passes through the opening on the front side of the installation groove 2 and the wire - passing hole 31 of the wiring frame, extends into the wiring frame, and the screw 4 is rotated downward. The screw 4 presses down the second plate body 52, so that the second plate body 52 presses the wire tightly.

[0027] The connecting plate 53 includes a third plate body 531 and a fourth plate body 532. One end of the third plate body 531 is connected to the first plate body 51, the other end is connected to the fourth plate body 532, the other end of the fourth plate body 532 is connected to the second plate body 52, and the end of the fourth plate body 532 connected to the third plate body 531 is high, and the end connected to the second plate body 52 is low.

[0028] As Figure 5 shown, when the height of the end of the wire is less than the distance between the second plate body 52 and the inner bottom surface of the wiring frame, the screw 4 presses down the second plate body 52, and the second plate body 52 bends downward to press the wire tightly, and the first plate body 51 abuts against the wiring frame. As Figure 6As shown, when the height of the end of the wire is greater than the distance between the second plate body 52 and the inner bottom surface of the wiring frame, when the wire is inserted, the fourth plate body 532 plays a guiding role. The wire pushes the wire pressing plate 5 to rise through the fourth plate body 532, and the first plate body 51 and the wiring frame no longer abut. After the wire is inserted, the screw 4 is rotated to press the second plate body 52 against the wire.

[0029] The first through hole 511 is an oval hole. On the one hand, the oval hole makes the wire pressing plate 5 rise more flexibly. On the other hand, as Figure 7 shown, on the basis of Figure 6 , the oval hole enables the wire pressing plate 5 to continue to rise obliquely, so that the terminal can be applicable to thicker wire ends.

[0030] A base cover 6 is connected to the base 1. The base cover 6 is provided with a second through hole 61 for screwing the screw 4, and the base 1 is provided with a card slot 12. The base cover 6 is provided with a clamping block 62 that cooperates with the card slot 12.

[0031] The front and rear inner walls of the installation groove 2 are provided with first convex blocks 21 whose widths gradually increase from top to bottom. A stop block 22 is provided between the lower ends of the first convex blocks 21 and the base 1. The front and rear end faces of the left and right side walls of the wiring frame are provided with second convex blocks 33 whose widths gradually decrease from top to bottom. After the wiring frame is placed in the installation groove 2, the first convex blocks 21 are located above the second convex blocks 33, and the stop block 22 is located in front of and behind the wiring frame, so that the wiring frame is limited within the wiring frame.

[0032] As Figures 8 - 10 shown, the second embodiment of the present invention is different from the first embodiment in that: the base 1 includes an end cover 13 and a plurality of splicing units 14. The installation groove 2 is arranged in the splicing unit 14. The end cover 13 and the plurality of splicing units 14 are spliced in sequence to form the base 1. The base 1 adopts a splicing structure, and the wiring quantity of the terminal can be flexibly adjusted according to requirements. Moreover, the producer only needs a set of base 1 molds and does not need to separately manufacture base 1 molds for each wiring quantity.

[0033] The end cover 13 is provided with a connecting column 15. One side of the splicing unit 14 that is connected to the end cover 13 is provided with a connecting hole 16, and the other side is provided with a connecting column 15. Or the end cover 13 is provided with a connecting hole 16. One side of the splicing unit 14 that is connected to the end cover 13 is provided with a connecting column 15, and the other side is provided with a connecting hole 16; the connecting column 15 and the connecting block are inserted and matched. The base 1 is provided with a surrounding edge 17 at the front side opening of the installation groove 2. The number of the connecting columns 15 is 4, three large and one small, and the corresponding connecting holes 16 are three large and one small. The setting of three large and one small makes it convenient to determine the directions of the end cover 13 and the splicing unit 14 during assembly and prevents reverse installation.

[0034] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, simple modifications and substitutions made by ordinary technicians in the field are within the protection scope of the present utility model.
