However, the existing stud terminal clamps usually use bolts to directly squeeze and fix the wires. This connection method is easily affected by factors such as temperature changes and vibrations, which can cause the bolts to loosen, affecting the stability of the electrical connection. In addition, the small contact area between the bolts and the wires will limit the conductive area, often causing the wires to be damaged due to excessive force, thereby increasing resistance and causing severe local heating.

[0010] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0011] like Figure 1As shown, a method for installing a stud terminal clamp adopts a stud terminal clamp, the stud terminal clamp includes a wire mechanism, a fastening mechanism for connecting the stud, the wire mechanism is connected to the side wall of the fastening mechanism, the wire mechanism includes a wire hole, a wire gasket, three threaded holes and a bolt, the wire hole is arranged along the axial direction of the wire mechanism, and the wire gasket is placed in the wire hole. An inverted step groove is provided at the middle of the top of the fastening mechanism, two slide grooves are provided on the side wall of the inverted step groove, and an annular groove arranged along the circumference of the inverted step groove is provided at the bottom of the slide groove, and the slide groove is connected with the annular groove. A circular groove of the same diameter is further provided downward on the bottom wall of the inverted step groove, and a through hole matching with the stud is provided at the bottom of the circular groove. An inverted cone matching with the inverted step groove is provided inside the inverted step groove, and an internal thread matching with the stud is provided at the center of the inverted cone; a plurality of grooves are evenly distributed along the circumference of the top of the inverted cone, and the two ends of the groove pass through the conical surface and the internal thread surface of the inverted cone. Two sliders are provided in the middle of the conical surface of the inverted cone, and the sliders are slidably provided in the slide groove. After the slider slides to the bottom of the slide groove, it can continue to slide along the annular groove, so that the connection direction of the wire mechanism can be changed. Furthermore, a plurality of conical grooves are evenly arranged along the circumference at the bottom of the annular groove, a column groove is arranged at the top of the slider, a spring is arranged at the bottom of the column groove, and a ball is arranged at the top of the spring. The ball can slide in and out of the conical groove, thereby stabilizing the direction of the wire mechanism.

[0012] Wire spacers such as Figure 3 The wire gasket is an integrated part consisting of three arc-shaped platforms with decreasing thickness and width from right to left. The three arc-shaped platforms of the gasket have an inwardly concave arc groove at the connection point, which is conducive to squeezing the external wire and buckling the wire to prevent it from loosening. The upper surfaces of the three arc-shaped platforms are cut out with a circular platform with a diameter consistent with the size of the three threaded holes. Figure 4 , its quasi-circular platform is aligned with the threaded hole of the wiring mechanism, and the bolt passes through the threaded hole to exert pressure on the quasi-circular platform, and then the platform disperses the local pressure to the gasket as a whole and then squeezes and fits the external wire. The bottom of the bolt is embedded in the quasi-circular platform of the wire gasket to prevent the gasket from being pulled out. Specifically: a square column is set at the bottom of the bolt, and a pin is set on the edge of the square column near the bottom end. A radial groove is set on the arc side of the platform, and the pin and the radial groove are slidably matched. A protrusion with the same length as the gasket is set on the side of the gasket that fits the wire. Figure 5 The size of the protrusions on the arc-shaped platform gradually increases from right to left, and is used to embed external wires and squeeze the wires to both sides to fit the wiring holes, thereby increasing the conductive area.

[0013] During installation, first place the inverted cone in the inverted cone slot, and the slider is located in the slot. Then pass the wiring stud through the through hole to connect with the inner thread of the inverted cone, and further rotate the fastening mechanism to achieve the connection between the fastening mechanism and the wiring stud. When connecting the wire externally, first insert the wire and the gasket into the wiring hole together, align the quasi-circular platform of the gasket with the threaded hole of the wiring mechanism, and then insert the three bolts through the threaded holes and apply pressure to the quasi-circular platform of the gasket, so that the gasket disperses the local pressure to the gasket as a whole and then squeezes the wire to avoid damage to the wire due to excessive local pressure. At the same time, the quasi-circular platform of the gasket is embedded in the bottom of the bolt to prevent the gasket from being directly pulled off. The inner protrusion of the gasket is embedded in the wire under pressure, so that the wire is squeezed to both sides and fits the inner wall of the wiring hole to increase the conductive area. The arc groove at each level of the gasket connection will enable the adjacent arc platforms to have the ability to bend relatively, and then the space for squeezing the wire is different. With the different thickness and width, the wire fork contacts the back of the gasket to increase the contact area with the wire. The gasket is narrow on the left and thick on the right, which makes the space at the end of the wiring hole larger than one end of the wiring hole, increases the resistance of the wire being pulled outward, and improves the stability of the wiring clamp.
