[0027] Embodiment one: a connecting terminal, referring to Figure 1 and Figure 2, including a terminal body 1, the terminal body 1 is laid along the length direction of the self and is provided with a limiting groove 11, the terminal body 1 is sequentially provided with a first clamping part 2 for clamping and fixing the connecting wire and a second clamping part 3 for clamping and fixing the inner core of the connecting wire along the length direction of the limiting groove 11, the limiting groove 11 is provided with a connecting part for abutting and fixing the external terminal at the end;

[0028] The first clamping part 2 includes a first outer clamping plate 21 and a second outer clamping plate 22 arranged on both sides of the limiting groove 11 respectively, and the wire is clamped by the mutual extrusion between the first outer clamping plate 21 and the second outer clamping plate 22;

[0029] The second clamping part 3 includes a first inner clamping plate 31 and a second inner clamping plate 32 arranged on both sides of the limiting groove 11 respectively, and the inner core of the wire is clamped by the mutual extrusion between the first inner clamping plate 31 and the second inner clamping plate 32;

[0030] The first clamping part 2 is respectively provided with a first bending assembly 4 on the first outer clamping plate 21 and the second outer clamping plate 22, or / and the second clamping part 3 is respectively provided with a second bending assembly on the first inner clamping plate 31 and the second inner clamping plate 32, and the bending of the wire clamped by the first clamping part 2 and the bending of the inner core clamped by the second clamping part 3 are deepened by the first bending assembly 4 and the second bending assembly respectively.

[0031] In the implementation of the embodiment, the wire is placed in the limiting groove 11, and then the wire is clamped by extruding the first clamping part 2 and the inner core of the wire is clamped by extruding the second clamping part 3, and then the terminal body 1 and the external terminal are abutted and fixed by the connecting part, so as to realize the stable connection among the terminal body 1, the wire and the external terminal;

[0032] Based on the stable connection among the terminal body 1, the wire and the external terminal, the bending of the wire clamped by the first clamping part 2 and the bending of the inner core clamped by the second clamping part 3 are deepened by the first bending assembly 4 and the second bending assembly respectively, so that the abutting area between the first clamping part 2, the second clamping part 3 and the wire and the inner core of the wire can be increased respectively when the first clamping part 2 and the second clamping part 3 are fixed, the stability of the clamping is increased, and the connection yield rate and the service life of the terminal are improved.

[0033] Specifically, the first bending assembly 4 comprises a first support area 41 and a first bending area 42 arranged in sequence on the first outer clamping plate 21 or / and the second outer clamping plate 22 in a direction away from the limiting groove 11, and the thickness of the first bending area 42 is smaller than the thickness of the first support area 41.

[0034] The first clamping part 2 is extruded by external force. Due to the different thicknesses of the first bending area 42 and the first support area 41, the bending degree and bending time between them are inconsistent. The first bending area 42 has a greater bending degree due to its smaller thickness. When the first outer clamping plate 21 and the second outer clamping plate 22 clamp the wire, the first bending area 42 is more likely to deform and is more closely fixed to the wire.

[0035] Specifically, the first bending assembly 4 and the second bending assembly have the same structure. The second bending assembly is arranged in the same structure as the first bending assembly 4, so as to make the second bending assembly more closely fixed to the inner core of the wire and reinforced connection.

[0036] The terminal body 1 of the embodiment is an integral molding structure, which is made of aluminum.

[0037] Embodiment two: a connecting terminal, referring to Figure 3 The difference between the embodiment and embodiment one is that the first bending assembly 4 comprises a second support area 43, a second bending area 44 and a third support area 45 arranged in sequence on the first outer clamping plate 21 or / and the second outer clamping plate 22 in a direction away from the limiting groove 11, and the thickness of the second bending area 44 is smaller than the thickness of the second support area 43 and the third support area 45.

[0038] The second support area 43, the second bending area 44 and the third support area 45 are arranged in sequence on the first outer clamping plate 21 in a direction away from the limiting groove 11. The first outer clamping plate 21 is extruded by external force, and the second bending area 44 is first bent, so as to make the first bending assembly 4 more closely fixed to the wire and reinforced connection.

[0039] Embodiment three: a connecting terminal, referring to Figure 4 The difference between the embodiment and embodiment one is that the first bending assembly 4 comprises a second support area 43, a second bending area 44 and a third support area 45 arranged in sequence on the first outer clamping plate 21 or / and the second outer clamping plate 22 in a direction away from the limiting groove 11, and the thickness of the second bending area 44 is smaller than the thickness of the second support area 43 and the third support area 45.

[0040] Embodiment four: a connecting terminal, referring toFigure 5 The difference between the embodiment and the embodiment one is that the first bending assembly 4 comprises a thickness of the first outer clamping plate 21 or / and the second outer clamping plate 22 gradually increases in the direction away from the limiting groove 11. By using the thickness difference, the bending degree and the bending time of the first bending assembly 4 under the influence of external force are inconsistent, so as to promote the first bending assembly 4 to be more fitted on the wire for clamping and fixing, reinforcing the connection.

[0041] The rest of the embodiment is the same as the embodiment one, and the features not explained in the embodiment are explained by the embodiment one, which will not be described here.
