[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution: a combined welding and crimping connector socket, including a socket body 1 and an installation groove 15, the installation groove 15 is arranged in an array inside the socket body 1, a through hole is arranged above the socket body 1, a grounding pin 2 is connected in the installation groove 15 inside the socket body 1, and a connecting block 16 is connected above the grounding pin 2, and the connecting block 16 is connected by a bolt connection and a grounding pressure bolt 3, the grounding pressure bolt 3 and the first pressure bolt 6 are made of metal, and the terminal head 8 is connected to the outside;

[0026] First, when in use, after taking out the grounding pin 2, insert the grounding pin 2 into the installation groove 15 inside the socket body 1, and then screw in the grounding pressure bolt 3 through the through hole above the socket body 1, so that the grounding pressure bolt 3 is connected to the connecting block 16 above the grounding pin 2;

[0027] Inside the installation groove 15 of the socket body 1, a long male pin 4 and a short male pin 5 are connected. The long male pin 4 and the short male pin 5 are arranged in an array inside the socket body 1. Above one end of the long male pin 4 and the short male pin 5, they are both connected to a terminal head 8 through a first crimping bolt 6. And above the first crimping bolt 6, a fixing block 7 is connected. Also, the short male pin 5 is connected to the terminal head 8 through the first crimping bolt 6. Inside the socket body 1, it is connected to a long bent welding pin 9 and a short bent welding pin 10 through a snap - connection mechanism. The snap - connection mechanism includes a push rod 13, and the push rod 13 is connected to the inside of the socket body 1. In front of the push rod 13, a snap block 14 is connected. The front of the snap block 14 is engaged with the card slots inside the long bent welding pin 9 and the short bent welding pin 10. Inside the long bent welding pin 9 and the short bent welding pin 10, a spring 11 is connected. And in front of the spring 11, a stop block 12 is connected. One end of the long male pin 4 and the short male pin 5 penetrates through the socket body 1 and is connected to the outside. One end of the long bent welding pin 9 and the short bent welding pin 10 penetrates through the socket body 1 and is connected to the outside;

[0028] At this time, the long male pin 4, the short male pin 5 and the socket body 1 are fixed. The fixation of the long male pin 4 and the short male pin 5 in the crimping area relies on the annular steps on the male pins, which are hard - pressed into the plastic part. The male pins are fixed in the plastic part by the front and rear two annular steps. In addition, the tail of the male pin is designed with a flat surface, which can provide a larger contact area, thus ensuring reliable contact. After connecting the terminal head 8 to the outside, the terminal head 8 is connected to one end of the long male pin 4 and the short male pin 5 through the first crimping bolt 6. At the same time, the rectangular fixing block 7 on the first crimping bolt 6 can make the connection effect better. At this time, the long bent welding pin 9 and the short bent welding pin 10 can be hard - pressed into the plastic part by interference fit. At the same time, the push rod 13 in the socket body can be started to drive the snap block 14 to move upward, so that the snap block 14 is engaged with the card slots inside the long bent welding pin 9 and the short bent welding pin 10 for fixation. Since a spring 11 is arranged inside the front end of the long bent welding pin 9 and the short bent welding pin 10, and the spring 11 is connected to the stop block 12 above, the long bent welding pin 9 and the short bent welding pin 10 cannot move inward during use. When movement is required, only need to press down the stop block 12 to make the internal spring 11 contract, then the long bent welding pin 9 and the short bent welding pin 10 can be moved. In the socket body 1, there are a crimping area and a welding area, which enables a connector to perform the functions of two connectors, greatly reducing the overall volume of the PCB board and significantly improving the production efficiency at the same time.

[0029] Working principle: When using the combined welding and crimping connector socket, first, after taking out the grounding pin 2 during use, insert the grounding pin 2 into the installation groove 15 inside the socket body 1, and then screw in the grounding crimping bolt 3 through the through-hole above the socket body 1, so that the grounding crimping bolt 3 is connected to the connecting block 16 above the grounding pin 2. At this time, fix the long male pin 4 and the short male pin 5 to the socket body 1. The fixing of the long male pin 4 and the short male pin 5 in the crimping area relies on the annular steps on the male pins, which are hard-pressed into the plastic part, and the male pins are fixed in the plastic part by the front and rear two annular steps. In addition, the tail of the male pin is designed with a flat surface, which can provide a larger contact area, thus ensuring reliable contact. After connecting the terminal head 8 to the outside, connect the terminal head 8 to one end of the long male pin 4 and the short male pin 5 through the first crimping bolt 6. At the same time, the rectangular fixing block 7 on the first crimping bolt 6 can make the connection effect better. At this time, the long bent welding pin 9 and the short bent welding pin 10 can be hard-pressed into the plastic part by interference fit. At the same time, the push rod 13 in the socket body can be started to drive the clamping block 14 to move upward, so that the clamping block 14 is engaged with the clamping grooves inside the long bent welding pin 9 and the short bent welding pin 10 for fixation. Since a spring 11 is arranged inside the front ends of the long bent welding pin 9 and the short bent welding pin 10, and the spring 11 is connected to the stop block 12 above, the long bent welding pin 9 and the short bent welding pin 10 cannot move inward during use. When movement is required, only press the stop block 12 to contract the internal spring 11 to move the long bent welding pin 9 and the short bent welding pin 10. The socket body 1 is provided with a crimping area and a welding area, which enables a connector to perform the functions of two connectors, greatly reducing the overall volume of the PCB board and significantly improving the production efficiency at the same time.
