[0072] The detailed description and technical contents of the present invention are described as follows with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0073] like Figures 4 to 9 As shown, the present invention provides a terminal block multi-contact conduction structure for electrically conducting with a wire 8. The multi-contact conduction type conductive terminals (referred to as conductive terminals) T1 and T2 include a terminal body 1 and a conductive contact wall 2. The conductive contact wall 2 is fixedly arranged on the terminal body 1. A conductive contact surface 21 for supporting the wire 8 is formed on the conductive contact wall 2. The terminal body 1 defines a wire feeding direction and a lateral direction perpendicular to the wire feeding direction (neither of which is shown in the figure), and the side where the wire 8 contacts the conductive contact surface 21 is set as the lower side. The terminal body 1 is also provided with a wire pressing wall 3, and the wire pressing wall 3 can tightly contact the upper surface of the wire 8. When the wire 8 is inserted into the terminal block through the wire entry hole of the wiring terminal block (hereinafter referred to as the terminal block), the wire 8 slides along the conductive contact surface 21 of the conductive contact wall 2 into the terminal block. When the wire 8 is inserted to a certain depth, the wire 8 passes through the gap between the wire pressing wall 3 and the conductive contact surface 21, and the wire pressing wall 3 closely contacts the upper surface of the wire 8. In this way, when the wire 8 is clamped on the conductive contact surface 21 by the spring S in the terminal block, the wire 8 has at least three contact points with the conductive terminals T1 and T2, such as Figure 8 As shown, there are respectively a first contact point 81 where the spring piece S is opposite to the position where the clamped wire 8 is located, a second contact point 82 where the conductive contact surface 21 and the wire pressing wall 3 are opposite to the position where the clamped wire 8 is located, and a third contact point 83 where the wire pressing wall 3 contacts the wire 8. This effectively increases the number of contact points between the wire 8 and the conductive terminals T1 and T2, ensures the signal transmission stability of the wiring terminal block, and can effectively improve the current flow capacity of the terminal block, thereby realizing large current transmission.

[0074] The wire pressing wall 3 is formed with an inclined wire pressing surface 31 which is at an acute angle to the conductive contact surface 21, and a trumpet-shaped wire passing channel is formed between the inclined wire pressing surface 31 and the conductive contact surface 21, in which the gap at the incoming wire end is larger than the gap at the outgoing wire end, and the gap at the outgoing wire end of the trumpet-shaped wire passing channel is less than or equal to the diameter of the wire 8, and the gap at the incoming wire end of the trumpet-shaped wire passing channel is larger than the diameter of the wire 8. By designing the inclined wire pressing surface 31 on the wire pressing wall 3, a trumpet-shaped structure is formed between the inclined wire pressing surface 31 and the conductive contact surface 21, so as to guide the insertion of the wire 8, so that the wire 8 is smoothly inserted into the gap between the inclined wire pressing surface 31 and the conductive contact surface 21, and smoothly passes through the wire pressing wall 3 and the conductive contact wall 2 facing each other, so that the inclined wire pressing surface 31 and the conductive contact surface 21 can both be in close contact with the wire 8. In addition, the wire pressing wall 3 can also be designed as a convex arc surface or a cylindrical structure, which are all specific implementation structures that can be easily thought of by those skilled in the art according to the present invention, and all belong to the protection scope of the present invention.

[0075] The wire pressing wall 3 and the conductive contact wall 2 are bending pieces arranged at intervals on the terminal body 1. In detail, there is a first bending portion 11 between the terminal body 1 and the conductive contact wall 2, and a second bending portion 12 between the terminal body 1 and the wire pressing wall 3. The conductive contact wall 2 is bent relative to the terminal body 1 via the first bending portion 11, and the wire pressing wall 3 is bent relative to the terminal body 1 via the second bending portion 12. The terminal body 1 is bent to form the wire pressing wall 3 and the conductive contact wall 2, so that the overall structure of the conductive terminals T1 and T2 is simple and easy to manufacture. The wire pressing wall 3 can also be bent to form a V-shaped spring sheet structure to achieve close contact and plug-in avoidance with the wire 8.

[0076] In addition, if Figures 6 to 9 As shown, in order to ensure that the wire pressing wall 3 is bent relative to the terminal body 1, the terminal body 1 has a side protrusion 13 extending along the wire feeding direction, and the side protrusion 13 has a bevel 131 inclined relative to the conductive contact surface 21. The wire pressing wall is connected to the bevel 131 and is inclined along the bevel 131 to form the inclined wire pressing surface 31. Therefore, the wire pressing wall 3 can be inclined relative to the conductive contact wall 2 and spaced from each other as shown in the figure.

[0077] like Fig.10 and Fig.11In the conductive terminal T3 shown, a first wire-binding protrusion 4 is provided on the conductive contact surface 21, and the wire 8 on the conductive contact surface 21 is accommodated between the first wire-binding protrusion 4 and the terminal body 1. The first wire-binding protrusion 4 forms a first inclined surface 41 toward a side wall of the terminal body 1, and an obtuse angle is formed between the first inclined surface 41 and the conductive contact surface 21. There are two places on the circumferential outer wall of the wire 8 that are in close contact with the terminal body 1 and the first inclined surface 41, respectively. By providing the first wire-binding protrusion 4 on the conductive contact surface 21, the wire 8 is bound along the width direction (or transverse direction) of the conductive contact surface 21 by the first inclined surface 41 on the first wire-binding protrusion 4, so that the circumferential outer wall of the wire 8 is always in contact with the terminal body 1 and the first inclined surface 41, thereby increasing two contact points, which are (refer to Fig.15 As shown): a fourth contact point (component symbol not indicated) between the wire 8 and the terminal body 1 and a fifth contact point 84 between the wire 8 and the first inclined surface 41, the first wire bundle protrusion 4 is optimally arranged at the edge of the conductive contact surface 21 away from the terminal body 1 in the width direction (or transverse direction).

[0078] In other embodiments not shown in the drawings, the number of the first wire-binding protrusions 4 is at least two, and the at least two first wire-binding protrusions 4 are spaced apart and arranged side by side on the conductive contact surface 21 along the wire feeding direction, thereby increasing the number of contact points.

[0079] like Figures 12 to 15 In the conductive terminal T4 shown, a second wire-binding protrusion 5 is further provided on the conductive contact wall 2 (or the conductive contact surface 21), and the second wire-binding protrusion 5 and the first wire-binding protrusion 4 are arranged at intervals along the left-right direction (or transverse direction) on the conductive contact wall 2 (or the conductive contact surface 21), and the second wire-binding protrusion 5 forms a second inclined surface 51 toward the side of the first wire-binding protrusion 4, and an obtuse angle is also formed between the second inclined surface 51 and the conductive contact surface 21, and the wire 8 on the conductive contact surface 21 is supported on the first inclined surface 41 of the first wire-binding protrusion 4 and the second inclined surface 51 of the second wire-binding protrusion 5. A V-shaped wire harness structure is formed by cooperating the second inclined surface 51 on the second wire harness protrusion 5 with the first inclined surface 41 on the first wire harness protrusion 4, so that the wire 8 is always in contact with the first inclined surface 41 and the second inclined surface 51, and two contact points are added, namely the fifth contact point 84 where the wire 8 contacts the first inclined surface 41 and the sixth contact point 85 where the wire 8 contacts the second inclined surface 51. At the same time, it is convenient for the wire 8 to be smoothly inserted between the first inclined surface 41 and the second inclined surface 51. The second wire harness protrusion 5 is preferably set at the position where the conductive contact surface 21 is connected to the terminal body 1.

[0080] In this way, by forming a wire pressing wall 3 on the conductive terminal T4, the upper side surface of the wire 8 on the conductive contact surface 21 is contacted, and by arranging a first wire bundling protrusion 4 and a second wire bundling protrusion 5 on the conductive contact surface 21, and a first inclined surface 41 on the first wire bundling protrusion 4 and a second inclined surface 51 on the second wire bundling protrusion 5 support the side surface of the end section of the wire 8 along the wire feeding direction, and at the same time, the wire pressing wall 3 presses the upper side surface of the end of the wire 8, so that the contact points between the wire 8 and the conductive terminal T4 are effectively increased, which greatly improves the current flow capacity of the wiring terminal block after wiring, and also improves the performance stability of the terminal block, so that the wiring of the wire 8 is more stable.

[0081] The contact points between the first inclined surface 41 and the second inclined surface 51 and the wire 8 are located on the same cross section of the wire 8, and the contact point between the wire pressing wall 3 and the wire 8 is closer to the end of the wire 8 along the wire feeding direction than the contact point between the first inclined surface 41 and the second inclined surface 51 and the wire 8 (see Fig.14 The wire 8 is first inserted into the V-shaped wire support structure between the first inclined surface 41 and the second inclined surface 51, and then moves forward for a while, leaves the V-shaped wire support structure, enters between the conductive contact surface 21 and the wire pressing wall 3, and is finally pressed. In this way, the wire 8 will not be interfered with during the insertion process, and the resistance is small. Of course, these contact points can also be designed on the same cross section.

[0082] The wire feeding side of the first wire harnessing protrusion 4 along the wire feeding direction is a third inclined surface 42, and the wire feeding side of the second wire harnessing protrusion 5 along the wire feeding direction is a fourth inclined surface 52. A bell-shaped wire feeding structure with a gap gradually reduced along the wire feeding direction is formed between the third inclined surface 42 and the fourth inclined surface 52. The bell-shaped wire feeding structure formed by the third inclined surface 42 and the fourth inclined surface 52 can facilitate the wire 8 to smoothly enter between the first wire harnessing protrusion 4 and the second wire harnessing protrusion 5 during the insertion process without interference.

[0083] The first harness protrusion 4 and the second harness protrusion 5 are both V-shaped convex structures formed by stretching on the conductive contact wall 2. The first harness protrusion 4 and the second harness protrusion 5 are formed by stretching on the conductive contact wall 2, which has a simple structure and is easy to manufacture.

[0084] The terminal body 1 defines an insertion terminal for the wire 8 to be inserted along the wire feeding direction, and the wire pressing wall 3, the first wire-binding protrusion 4 and the second wire-binding protrusion 5 are all located above the conductive contact surface 21 and close to the insertion terminal for the wire 8 to be inserted along the wire feeding direction. This facilitates the rapid insertion of the front section of the wire 8, and at the same time, does not affect the spring S clamping the wire 8.

[0085] The conductive contact surface 21 is also provided with a sawtooth convex stopper 6 and a plurality of concave-convex anti-slip structures 7 arranged at intervals along the wire feeding direction. The sawtooth convex stopper 6 and the concave-convex anti-slip structure 7 can increase the pulling force of the wire 8 and prevent the wire 8 from being pulled out by force.

[0086] like Figures 16 to 18 As shown, the conductive contact wall 2 (or the conductive contact surface 21) is further provided with a third wire-binding protrusion B, and the third wire-binding protrusion B is located between the first wire-binding protrusion 4 and the second wire-binding protrusion 5. The first wire-binding protrusion 4, the second wire-binding protrusion 5 and the third wire-binding protrusion B together constitute a wire-binding protrusion group (without component symbols). The wire-binding protrusion group is provided with at least two or at least three (such as Fig.16 The wire-binding protrusion groups shown are three), and at least three wire-binding protrusion groups are spaced apart and arranged side by side on the conductive contact surface 21 along the wire feeding direction. In detail, the first wire-binding protrusion 4, the second wire-binding protrusion 5 and the third wire-binding protrusion B of each wire-binding protrusion group are arranged together on the conductive contact wall 2 (or the conductive contact surface 21) in a lateral spaced manner, and the third wire-binding protrusion B forms a first corresponding inclined surface B1 on the side facing the first wire-binding protrusion 4, and forms a second corresponding inclined surface B2 on the side facing the second wire-binding protrusion 5, and the first corresponding inclined surface B1 and the second corresponding inclined surface B2 also form obtuse angles with the conductive contact surface 21 respectively.

[0087] In this way, when there are two wires 8, one of the wires 8 on the conductive contact surface 21 is supported on the first inclined surface 41 of the first wire-binding protrusion 4 and the first corresponding inclined surface B1 of the third wire-binding protrusion B, and the other wire 8 on the conductive contact surface 21 is supported on the second inclined surface 51 of the second wire-binding protrusion 5 and the second corresponding inclined surface B2 of the third wire-binding protrusion B. Therefore, even if two wires 8 are supported on the conductive contact surface 21, they both have the same number of contact points as when one wire 8 is supported.

[0088] In order to match the conductive contact wall 2 with multiple wire harness protrusion groups, a corresponding spring sheet 9 is designed. The spring sheet 9 includes a supporting portion 93, a spring sheet bending portion 94 and at least two crimping portions. The spring sheet bending portion 94 is connected between the supporting portion 93 and the at least two crimping portions, and the supporting portion 93 is connected to a part of the spring sheet bending portion 94, and the at least two crimping portions are all connected to another part of the spring sheet bending portion 94. As for the at least two crimping portions, they include a first crimping portion 91 and a second crimping portion 92. The supporting portion 93 and all the crimping portions are elastically supported between the conductive terminal and all the wires 8, respectively. The first crimping portion 91 and the second crimping portion 92 can be crimped to any part of the wire 8. In this embodiment, Fig.17As shown, the first crimping portion 91 and the second crimping portion 92 are respectively crimped to the wire 8 at the position between any two adjacent wire harnessing protrusion groups, and are both crimped to the upper surface of the wire 8. In this way, it can be ensured that the wire 8 and the conductive contact surface 21 have the same number of contact points as mentioned above.

[0089] In detail, the first crimping portion 91 has two crimping arms 911, and the second crimping portion 92 also has two crimping arms 921. The two crimping arms 911 of the first crimping portion 91 respectively crimp the two wires 8 that have been supported on the conductive contact surface 21, and the two crimping arms 921 of the second crimping portion 92 also respectively crimp the two wires 8 that have been supported on the conductive contact surface 21, so the spring sheet 9 can indeed crimp each wire 8.

[0090] In other embodiments not shown in the figures, if there is only one wire 8 and there are at least two of the V-shaped wire support harness structures, the first crimping portion 91 and the second crimping portion 92 of the spring sheet 9 will correspondingly have only one crimping arm 911, 921, so that the crimping arm 911 of the first crimping portion 91 and the crimping arm 921 of the second crimping portion 92 respectively crimp the wire 8 at the position corresponding to any adjacent two V-shaped wire support harness structures.

[0091] In summary, the terminal block multi-contact conduction structure of the present invention can achieve the expected purpose and effect, and can solve the deficiencies of the prior art, so a patent application is filed.

[0092] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
