[0039] The following will further describe the present application in detail Figures 1-5 with reference to the attached drawings.

[0040] The embodiment of the present application discloses an orbital wiring terminal. Refer to Figure 1 and Figure 2The terminal comprises a terminal housing 1, a terminal cover 6, a spring pressure piece 3, a conductive bridge 2 and an unlocking piece 4, wherein the terminal housing 1, the terminal cover 6 and the unlocking piece 4 are all made of non-conductive materials, the conductive bridge 2 is made of conductive materials, and the spring pressure piece 3 is made of metal materials. The terminal cover 6 is buckled on the terminal housing 1 to protect the internal parts. The conductive bridge 2 is used to connect the wires to form a passage, which can limit the wires from escaping from the terminal housing 1 and ensure the stability of the connection. The unlocking piece 4 can unlock the restriction of the spring pressure piece 3 on the wires to pull out the wires.

[0041] Reference Figure 1 and Figure 2 Specifically, a clamping column 61 is integrally formed on one side of the terminal cover 6 facing the terminal housing 1. The clamping column 61 is set as a circular column, and the end of the clamping column 61 has a rounded corner. The terminal housing 1 is provided with a clamping groove 14 for insertion. The clamping column 61 can be inserted into the clamping groove 14 by interference fit, thereby fixing the terminal housing 1 and the terminal cover 6. Further, in order to reduce the possibility that the clamping column 61 is difficult to insert into the clamping groove 14 due to processing errors, the clamping groove 14 is set as a waist-shaped groove, so that the side wall of the clamping groove 14 has a deformation space, so that the clamping column 61 can be smoothly inserted. A connecting seat 16 is also provided at the lower end of the terminal housing 1, and the terminal housing 1 can be connected to the corresponding track through the cooperation of the connecting seat 16.

[0042] Reference Figure 1 and Figure 3 In this embodiment, the main body of the conductive bridge 2 is a rectangular long plate structure made of conductive metal. Electrical connection plates 21 are fixed to the upper surfaces of both ends of the conductive bridge 2. When the wire is inserted into the wiring hole 11, the inner wall of the electrical connection plate 21 abuts against the wire to form an electrical connection, and the outer wall of the electrical connection plate 21 abuts against the terminal housing 1 to limit the electrical connection plate 21.

[0043] Reference Figure 2 and Figure 3 In this embodiment, a wiring hole 11 for wire insertion is provided on the upper surface of the terminal housing 1, and a spring pressure piece 3 is arranged inside the wiring hole 11. The spring pressure piece 3 is in a "V" shape as a whole, and includes a positioning end 31, an elastic end 32, and a connecting portion 33 connected between the positioning end 31 and the elastic end 32, wherein the connecting portion 33 is a semicircular metal sheet, and a positioning column 15 is integrally formed on the terminal housing 1, and the positioning column 15 is a cylinder. The inner side of the connecting portion 33 is wound around the positioning column 15, and cooperates with the baffle plate arranged in the terminal housing 1, so that the connecting portion 33 can be positioned outside the positioning column 15.

[0044] For the convenience of understanding, the side of the spring clip 3 facing the positioning post 15 is the inner side, and the side facing away from the positioning post 15 is the outer side. The positioning end 31 extends downward, and the outer side of the positioning end 31 abuts against the baffle provided inside the terminal housing 1. The elastic end 32 extends obliquely downward toward the wiring hole 11 and is located inside the wiring hole 11. When a wire is inserted into the wiring hole 11, it can first abut against the outer side of the elastic end 32 and drive the elastic end 32 to rotate toward the positioning end 31. When the wire is inserted in place, the resilience of the elastic end 32 can drive the wire to tightly abut against the side wall of the electrical contact piece 21. At the same time, due to the obliquely downward arrangement of the elastic end 32, the wire is restricted from sliding toward the outside of the wiring hole 11, thereby clamping and fixing the wire.

[0045] Referring to Figure 3 and Figure 4 In this embodiment, the unlocking member 4 is an unlocking button 41. A sliding groove is provided on the upper surface of the terminal housing 1, and the unlocking button 41 can slide up and down in the sliding groove. The lower end of the unlocking button 41 abuts against the outer side wall of the elastic end 32. When the unlocking button 41 is pressed, it can drive the elastic end 32 to rotate toward the inner side, so that the elastic end 32 is separated from the wire. At this time, the wire can be pulled out upward. Preferably, in order to prevent the unlocking button 41 from slipping out of the sliding groove upward, a limiting block protrudes from the lower end side wall of the unlocking button 41, and the terminal housing 1 is correspondingly provided with a limiting groove for the block to slide up and down. When the unlocking button 41 slides upward under the action of the elastic force until the upper surface of the limiting block abuts against the side wall of the limiting groove, the unlocking button 41 is restricted from continuing to slide upward. At this time, the upper end of the unlocking button 41 is not higher than the upper surface of the terminal housing 1 to avoid accidentally touching the unlocking button 41.

[0046] Referring to Figure 3 and Figure 4 In this embodiment, optionally, a retaining piece 22 is further provided at the end of the conductive bridge 2. The retaining piece 22 is located on the side of the electrical contact piece 21 away from the terminal housing 1 and is preferably parallel to the terminal housing 1; the spring clip 3 is arranged between the terminal housing 1 and the retaining piece 22, so that the retaining piece 22 can limit the spring clip 3 from moving away from the terminal housing 1, thereby improving the stability of the spring clip 3. Further, preferably, two sets of electrical contact pieces 21 and retaining pieces 22 are provided at the same end of the conductive bridge 2. For one set, the electrical contact piece 21 is inserted between the outer side wall of the elastic end 32 and the terminal housing 1, and the retaining piece 22 is located outside the elastic end 32; for the other set, the electrical contact piece 21 is inserted between the outer side wall of the positioning end 31 and the terminal housing 1, and the retaining piece 22 is located outside the positioning end 31; further improving the stability of the spring clip 3.

[0047] Referring to Figure 3 and Figure 4, in this embodiment, the conductive bridge 2 is detachably installed in the terminal housing 1. Specifically, a support plate 12 is fixed in the terminal housing 1 along the horizontal length direction. A receiving groove for inserting the conductive bridge 2 is formed above the support plate 12, and the conductive bridge 2 can be snapped into the receiving groove. Since interference will occur between the power connection piece 21 at the end and the spring pressing piece 3, in order to facilitate the insertion of the conductive bridge 2, a chamfer is formed on the side of the power connection piece 21 facing away from the blocking piece 22, that is, the side facing the terminal housing 1, and the inclined plane formed by the chamfer faces the direction of the spring pressing piece 3.

[0048] Refer to Figure 1 and Figure 4 , in this embodiment, the conductive bridge 2 extends along the length direction of the terminal housing 1, and a plurality of conductive bridges 2 can be arranged at intervals along the height direction of the terminal housing 1; in this embodiment, a total of three conductive bridges 2 are provided, and wiring holes 11 are correspondingly arranged at both ends of each conductive bridge 2 to cooperate with the spring pressing piece 3 to insert wires; the lengths of the three conductive bridges 2 increase in sequence from top to bottom, and all the wiring holes 11 are arranged in a stepped and staggered manner, so that it is convenient to insert wires at both ends of each conductive bridge 2. This setting method can connect multiple groups of wires at the same time.

[0049] Refer to Figure 1 and Figure 4 , in this embodiment, since the conductive bridge 2 is relatively long, in order to improve the anti-bending property of the conductive bridge 2, a reinforcing rib 23 is fixed on the upper surface of the conductive bridge 2, and the reinforcing rib 23 extends along the length direction of the conductive bridge 2. In order to adapt to the structure in the terminal housing 1, a plurality of reinforcing ribs 23 can be arranged at intervals along the length direction.

[0050] Refer to Figure 3 and Figure 4 , further optionally, the terminal also includes a jumper. The jumper can connect two adjacent upper and lower wire bridges. Specifically, the jumper can be a rectangular rod supported by a conductive material (not shown in the figure). A jumper channel 13 for inserting the jumper is formed on the terminal housing 1. The jumper channel and the terminal housing 1 are also made of non-conductive materials; the jumper channel 13 extends upward to the upper surface of the terminal housing 1 and is staggered from the position of the wiring hole 11; a jumper hole 24 for inserting the jumper is formed between two adjacent upper and lower conductive bridges 2. The jumper channel 13 and the jumper holes 24 on two adjacent conductive bridges 2 are located on the same vertical line, so that after the jumper is inserted into the jumper channel 13 and passes through the two jumper holes 24, the two adjacent wire bridges can be electrically connected. In this embodiment, a jumper channel 13 is arranged between the uppermost conductive bridge 2 and the middle conductive bridge 2; a jumper channel 13 is arranged between the middle conductive bridge 2 and the lowermost conductive bridge 2; a jumper channel 13 is arranged on the lowermost conductive bridge 2, and this jumper channel 13 can be used to connect two adjacent terminals.

[0051] Refer toFigure 1 and Figure 5 , in an optional embodiment, the terminal also includes a connecting buckle 5, which is buckled on two adjacent upper and lower conductive bridges 2 during use. The connecting buckle 5 is made of a conductive material, so that it can replace the jumper to connect two adjacent conductive bridges 2; at the same time, the connecting buckle 5 can further strengthen and fix the adjacent upper and lower conductive bridges 2. It should be noted that in actual use, the connecting buckle 5 and the jumper are alternative solutions, that is, one of them is selected according to actual needs for connection.

[0052] Specifically, the connecting buckle 5 includes a connecting rod 51, abutting rods 52 arranged on both sides of the connecting rod 51, and buckling rods 53 arranged at the upper and lower ends of the connecting rod 51; correspondingly, grooves for the connecting rod 51 to be clamped can be opened on the side walls of the support rod and the conductive bridge 2. When the connecting buckle 5 is arranged on the terminal housing 1 and buckled on two adjacent upper and lower conductive bridges 2, the buckling rod 53 at the upper end abuts against the upper surface of the upper conductive bridge 2, and the buckling rod 53 at the lower end abuts against the lower surface of the lower support plate 12. The upper surfaces of the abutting rods 52 on both sides abut against the lower surface of the upper support plate 12, and the lower surfaces of the abutting rods 52 abut against the upper surface of the lower conductive bridge 2. At this time, the connecting buckle 5 can conduct the two conductive bridges 2 and fix and abut the conductive bridges 2 on the corresponding support plates 12.

[0053] The implementation principle of an orbital terminal in an embodiment of the present application is as follows: when installing the terminal, first snap the spring clip 3 and the conductive bridge 2 into the corresponding positions in sequence. The connecting buckle 5 can be fixed if necessary, and finally the terminal cover 6 is covered on the terminal housing 1. During use, just insert the wire into the corresponding wiring hole 11 according to the need to form a circuit. If you want to pull out the wire, first press the unlocking button 41 to pull out the wire. At the same time, according to the need, when the connecting buckle 5 is not connected and the conductive bridge 2 needs to be connected, the corresponding jumper can be inserted to connect the corresponding conductive bridge 2 to merge the circuit.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
