[0020] It will be understood that when an element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0021] The following drawings and specific embodiments further describe the present invention: Figures 1 to 3 A square substrate conductive terminal is shown, comprising a wiring portion 1, a mounting portion 2 and a plug-in portion 3 which are integrally formed and sequentially connected from front to back, wherein the mounting portion 2 is a square tubular structure formed by bending and splicing the substrate, a positioning spring piece 4 is formed on the lower side of the mounting portion 2, and a bent splicing portion is formed on the upper side, wherein the bent splicing portion comprises a left splicing piece 5 and a right splicing piece 6, and a reinforcing connection structure is connected between the left splicing piece 5 and the right splicing piece 6.

[0022] In the utility model, a reinforced connection structure is connected between the left splicing piece 5 and the right splicing piece 6 on the upper side, thereby strengthening the stability of the left splicing piece 5 and the right splicing piece 6 after bending, and can prevent the left splicing piece 5 and the right splicing piece 6 from deforming to both sides, greatly improving the anti-deformation ability, and increasing the service life of the terminal.

[0023] See also Figure 1 , Figure 3 As shown, the reinforced connection structure includes a notch 21 provided on the left splicing piece 5, and a connecting plug 22 which can be inserted into the notch 21 is provided on the right splicing piece 6; when the left splicing piece 5 and the right splicing piece 6 are bent into shape, the connecting plug 22 is inserted into the notch 21, thereby preventing the left splicing piece 5 and the right splicing piece 6 from deforming to both sides.

[0024] See also Figure 1 , Figure 2 As shown, the plug-in portion 3 includes two V-shaped spring pieces 31 arranged opposite to each other up and down, and a gap 32 for inserting a conductive plug is formed between the two V-shaped spring pieces 31; when the plug-in terminal is inserted into the gap 32 in actual use, the upper V-shaped spring piece 31 contacts the upper side surface of the plug-in terminal, and the lower V-shaped spring piece 31 contacts the lower side surface of the plug-in terminal, and the contact surface is large, thereby ensuring the electrical connection effect.

[0025] Furthermore, the V-shaped spring piece 31 includes a guide insert piece 41 and a connecting piece 42, the connecting piece 42 is connected to the mounting portion 2, and the angle between the guide insert piece 41 and the connecting piece 42 is 105-115°; thereby facilitating the insertion of the docking terminal.

[0026] The wiring part 1 is used to connect with a wire, wherein the wire generally includes an inner metal wire core conductor and a cable insulation layer covering the outer periphery of the metal wire core conductor.

[0027] See also Figure 1 As shown, the wiring part 1 includes a wire core clamping part for clamping the wire core and a cable clamping part for clamping the cable part.

[0028] Furthermore, the wire core holding portion includes a first wire pressing groove 61, and the first wire pressing groove 61 is formed by integrally bending two first arc-shaped pressing sheets 62 arranged on the left and right.

[0029] The cable holding portion includes a second wire pressing groove 71 disposed at the front end of the first wire pressing groove 61 , and the second wire pressing groove 71 is formed by integrally bending two second arc-shaped pressing sheets 72 spaced apart from each other on the left and right sides.

[0030] During operation, the metal core conductor in the wire is placed in the first crimping groove 61, and then riveted inwardly through the first arc-shaped sheet 62; then, the excess part of the wire, that is, the insulating layer wrapped by the wire, is placed in the second crimping groove 71, and then the insulating layer is clamped by the second arc-shaped pressing sheet 72, so that the wire is connected to the terminal.

[0031] Furthermore, there is a gap notch 81 between the first arc-shaped pressing piece 62 and the second arc-shaped pressing piece 72; when the wire is riveted and clamped, the first arc-shaped piece 62 can be riveted first, and then the second arc-shaped pressing piece 72 can be riveted, so that the first wire pressing groove 61 and the second wire pressing groove 71 can be operated separately, which can ensure the tight connection between the first wire pressing groove 61, the second wire pressing groove 71 and the wire, effectively ensure the stability of the connection between the wire and the terminal, and avoid the wire falling off.

[0032] An inwardly protruding flange strip 91 is connected to the bottom wall of the first wire crimping groove 61 and the side walls of the two first arc-shaped pressing plates 62; it can improve the tightness of contact between the wire and the inner wall of the first wire crimping groove 61, thereby effectively ensuring the stability of the connection between the wire and the terminal, and avoiding the wire from falling off the terminal.
