[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] In the process of producing through-cylinder connector sockets, the injection molding process is usually used. In this process, the pin is fixed in the mold as an insert, and then the socket is formed on the outside of the pin through the injection molding process. This process requires extremely high precision and attention to detail to ensure the matching between the socket and the pin and the stability of the connection. In order to further improve the sealing and stability of the connector, oil-resistant and high-temperature resistant glue is also applied between the pin and the socket during the production process. However, the cost of oil-resistant and high-temperature resistant glue is relatively high, which not only increases the production cost, but the glue application process itself also takes a certain amount of time, which may reduce production efficiency.

[0030] like Figure 1 , Figure 2As shown, in order to solve the above technical problems, the utility model provides a through-cylinder connector socket, including a socket body 1, a plurality of socket terminals 2, the plurality of socket terminals 2 are respectively arranged in corresponding terminal holes 11, the socket body 1 is provided with a plurality of terminal holes 11, and the socket terminal 2 is provided with a plurality of barbed steps 21. By providing the barbed steps 21 on the socket terminal 2, the barbed steps 21 and the socket body 1 are in interference contact, so that the barbed steps 21 can play a role of stopping retreat, and can enhance the mechanical locking force between the socket terminal 2 and the socket body 1, so that the socket terminal 2 is not easy to loosen after being inserted into the terminal hole 11, so that the connection stability and sealing performance between the socket terminal 2 and the socket body 1 can be ensured without using glue. That is, the utility model does not need additional glue to fix the socket terminal 2 and the socket body 1, which can reduce production costs, and can achieve rapid assembly during the production process, thereby improving production efficiency.

[0031] like Figures 1 to 4 As shown, in this embodiment, the socket terminal 2 is arranged in the terminal hole 11 by riveting. In addition, the apertures at both ends of the terminal hole 11 are larger than the aperture in the middle, so that the socket terminal 2 is connected to the socket body 1 by riveting. Since the barbed step 21 of the socket terminal 2 has a stop function, the parts of the socket terminal 2 located at both ends of the terminal hole 11 will become tighter and tighter during riveting. By riveting, the socket terminal 2 can be tightly combined with the socket body 1, improving the sealing and stability of the through-cylinder connector socket, and the riveting process is fast and reliable, making the entire assembly process faster and more efficient.

[0032] like Figure 1 , Figure 3 As shown, in this embodiment, a plug-in slot 12 is provided in the socket body 1, and at least a portion of the socket terminal 2 extends into the plug-in slot 12, so as to facilitate the connection between the socket terminal 2 and other components. The cooperation between the socket terminal 2 and the plug-in slot 12 can provide a more stable electrical connection, reduce the possibility of poor contact, and ensure the reliability of signal transmission.

[0033] like Figure 5 , Figure 6 As shown, in this embodiment, the socket terminal 2 includes a connecting portion 22 and a plug-in portion 23. The connecting portion 22 and the plug-in portion 23 are an integrated structure. The connecting portion 22 is arranged in the plug-in slot 12, and the plug-in portion 23 is arranged in the terminal hole 11, and the diameter of the connecting portion 22 is smaller than the diameter of the plug-in portion 23. In addition, the plug-in slot 12 of the socket body 1 is connected to the terminal hole 11. When installing, the plug-in portion 23 is installed in place when it is flush with the bottom surface of the plug-in slot 12 of the socket body 1. In addition, a plurality of barbed steps 21 are formed on the outer side wall of the plug-in portion 23, which increases the friction between the socket terminal 2 and the socket body 1, making the socket terminal 2 more secure in the socket body 1.

[0034] like Figure 5 , Figure 6 As shown, in this embodiment, a plurality of barbed steps 21 are arranged at equal intervals along the axial direction of the socket terminal 2, so that when the socket terminal 2 is inserted into the socket body 1, the stress is evenly distributed, reducing damage or deformation caused by stress concentration, making the contact between the socket terminal 2 and the socket body 1 more uniform and stable, thereby improving the stability of the overall connection. In addition, the barbed steps are arranged 360° around the outer side wall of the plug-in portion 23, which can limit the socket terminal 2 and further prevent the socket terminal 2 from falling out of the terminal hole 11.

[0035] like Figure 5 , Figure 6 As shown, in this embodiment, the barbed step 21 includes a first plane 211, a second plane 212, and an inclined surface 213. The first plane 211 is perpendicular to the second plane 212, and the first plane 211 is perpendicular to the central axis of the plug-in portion 23. The inclined surface 213 is located on the side of the second plane 212 away from the connecting portion 22, that is, the first plane 211 faces the plug-in slot 12 of the socket body 1. When installing, the plug-in portion 23 is inserted into the terminal hole 11 from the plug-in slot 12 of the socket body 1. The inclined surface 213 can play a guiding role, which facilitates the socket terminal 2 to smoothly enter the socket body 1 along the predetermined path, so that the assembler can more easily insert the socket terminal 2 into the socket body 1, simplifying the assembly process and improving the assembly efficiency. At the same time, the first plane 211 is perpendicular to the central axis of the plug-in portion 23, and the first plane 211 is perpendicular to the second plane 212. If the plug-in portion 23 of the socket terminal 2 is pulled out from the terminal hole 11, the first plane 211 can block the movement of the plug-in portion 23, so that the socket terminal 2 is not easy to loosen after insertion. That is, the first plane 211 plays a role in preventing the socket terminal 2 from being withdrawn. When the socket terminal 2 is subjected to an external force, the first plane 211 can provide necessary resistance to prevent the socket terminal 2 from accidentally falling off or withdrawing from the socket body 1 .

[0036] In this embodiment, there are four barbed steps 21 on the socket terminal 2. Of course, the barbed steps 21 can be designed to be five or six. In actual design, the number of barbed steps 21 on the socket terminal 2 can be designed according to actual needs. In addition, there are sixteen socket terminals 2. Of course, in actual design, the number of socket terminals 2 can be designed according to actual needs.

[0037] During assembly, the socket terminal 2 is inserted into the injection-molded socket body 1, and then the socket terminal 2 is tightly combined with the socket body 1 through riveting by a pneumatic punch, and an anti-backward structure is provided on the socket terminal 2. At the same time, combined with the characteristics of the terminal hole 11 being wide at the top and bottom and narrow in the middle, the socket terminal 2 can be limited, so that the socket terminal 2 is not easy to loosen after insertion. That is, the utility model can ensure the connection stability and sealing performance between the socket terminal 2 and the socket body 1 without using oil-resistant and high-temperature resistant glue, thereby reducing production costs and improving production efficiency. In addition, the use of a pneumatic punch riveting has good oil and high-temperature resistance after riveting, and the use of a pneumatic punch makes the riveting process more convenient, reduces the complexity of manual operation, and also reduces the error rate during operation. At the same time, due to the simplification of the process and the improvement of the degree of automation, the labor cost is effectively controlled, and the overall production economic benefits are improved.
