[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] In this embodiment, if Figure 1-Figure 5 As shown, a pin-type PCB welding terminal includes a welding terminal body 101. The welding terminal body 101 is made of brass and has strong wear resistance, impact resistance, and expansion resistance, which is convenient for conducting large currents. The surface of the welding terminal body 101 is provided with a screw hole 102. The internal thread of the screw hole 102 is connected with a bolt. The upper end of the bolt is fixedly connected with a nut 103. The bolt matches the welding terminal body 101, and then the welding terminal body 101 is fixedly connected to the PCB board. The outer side of the welding terminal body 101 is symmetrically installed with pins 104. The pins 104 are symmetrically installed with the outer side of the welding terminal body 101. 04 is located in the middle of the four sides of the welding terminal body 101. The shape and direction of the pin 104 can be assembled according to the actual work requirements, and it has high applicability. It also includes an anti-slip part 200, which is arranged inside the welding terminal body 101 to prevent the bolt from slipping and falling off. Through the mutual cooperation between the welding terminal body 101 and the anti-slip part 200, the maximum torque is ensured, the slipping caused by the small number of thread turns is reduced, and the bolt is prevented from falling off from the welding terminal body 101 due to slight looseness, thereby causing the PCB board to be unable to be used normally;

[0027] Among them Figure 2-Figure 5 As shown, the anti-slip part 200 includes grooves 201 symmetrically arranged on both sides of the welding terminal body 101, and the opposite sides of the two grooves 201 are connected with threaded holes, and the other side of the threaded hole is provided with a slide groove 202, and the interior of the slide groove 202 is slidably connected with an arc plate 203, and the arc plate 203 is made of rubber material and has a limiting protection function. The arc plate 203 contacts with the bolt so that it can play a fixed limiting role on the bolt, and one side of the arc plate 203 is rotatably connected with a screw rod 204, so that the arc plate 203 has self-locking properties, and the screw rod 204 is threadedly connected with the threaded hole. One end of the screw rod 204 extends into the interior of the fixed groove 201 and is fixedly installed with a turning handle. Turning the turning handle can drive the screw rod 204 to rotate, and then drive the arc plate 203 to separate from the bolt, so as to realize the disassembly operation of the bolt, and avoid the slippage caused by the small number of thread turns due to the small thickness of the welding terminal body 101.

[0028] Among them Figure 3As shown, the outer side of the welding terminal body 101 is symmetrically provided with placement grooves 105, and the placement grooves 105 are arranged on each side of the welding terminal body 101, so as to facilitate the dispersion of multiple pins 104 in different directions, improve the space utilization rate, and improve the connection function of the wire. The pins 104 are slidably connected with the placement grooves 105, and a screw 106 is arranged on one side of the pin 104, which is convenient for limiting the pin 104, so that pins 104 of different sizes and different bending degrees can be installed, and the applicability of the pin 104 is improved. The pin 104 is fixedly connected with the welding terminal body 101 by the screw 106, which facilitates the pin 104 to better contact with the PCB board, enhances the current capacity of the pin 104, and increases the life of the welding terminal;

[0029] Among them Figure 1 As shown, the upper end of the welding terminal body 101 is symmetrically provided with legs 107, and the legs 107 are fixedly connected to the four corners of the top of the welding terminal body 101, and the legs 107 and the welding terminal body 101 are an integrated structure;

[0030] Among them Figure 1 As shown, the surface of the welding terminal body 101 is provided with a high-temperature matte tin layer, so that the welding terminal body 101 has a smooth surface texture without affecting the conductive effect;

[0031] Among them Figure 4 and Figure 5 As shown, the arc plate 203 is adapted to the arc shape of the bolt, the arc plate 203 is adapted to the size specification of the slide groove 202, and the arc plate 203 is slidably connected to the slide groove 202, so that when the bolt needs to be removed, the arc plate 203 can be stored in the slide groove 202 for easy operation.

[0032] Example 2

[0033] The difference from Example 1 is that Figure 6 and Figure 7 As shown, the anti-slip member 200 further includes a plurality of plug posts 205 disposed on the upper surface of the nut 103. The nut 103 and the welding terminal body 101 are fixedly connected via the plug posts 205. The plug posts 205 limit the bolts to prevent the bolts from moving in the horizontal and vertical directions.

[0034] Among them Figure 6 and Figure 7 As shown, the surface of the welding terminal body 101 is provided with a plurality of circular holes corresponding to the plug posts 205, so as to ensure the normal use of the welding terminal and improve the overall practicality.

[0035] When in use, select a suitable pin 104, and fix the pin 104 inside the placement groove 105 by means of the screw 106, so that the welding terminal body 101 and the pin 104 are fixed as a whole, and then the welding terminal is fixedly connected to the PCB board by means of a bolt matching the welding terminal body 101. The user tightens the screw 204 and the column 205, so that the arc plate 203 inside the slide groove 202 coincides with the outside of the bolt and the arc plate 203 is firmly clamped on the outside of the bolt, and then the corresponding circuit is connected to the welding terminal body 101, thereby realizing the working effect of the welding terminal.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
