Description

Technical Field

[0001] This utility model relates to the field of terminal technology, specifically to a test head terminal. Background Technology

[0002] A board-side male connector refers to the male portion of a connector mounted on a circuit board, typically used for connections between circuit boards or peripherals. The main function of a board-side male connector is to establish an electrical connection with the female connector via metal posts, enabling signal and data transmission. Test terminals are usually directly soldered to the PCB board. Current soldering methods mostly involve tin soldering. During soldering, the soldering iron needs to be close to the PCB board, which can easily lead to contact between the soldering iron and the PCB board, causing damage from heat. Furthermore, excessive solder can melt during soldering, resulting in multiple pins connecting through the solder, leading to a high scrap rate.

[0003] Therefore, this utility model provides a test head terminal. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a test head terminal that solves the problems mentioned in the background section. This invention achieves onboard functionality by soldering fixed feet and pins onto a PCB board. The male and female connectors on the board can form a reliable connection through the center conductors of the male and female connectors. The fixed structure ensures the stability of the fixed feet, preventing the male connector from shaking during operation and causing poor contact. Furthermore, soldering can be performed by heating the soldering structure, preventing the soldering iron from directly contacting the PCB board, ensuring the normal use of the PCB board, and preventing excessive solder melting and overflow, thus ensuring a high success rate of soldering.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a test head terminal, including a male connector mounted on a PCB board, a female connector mounted on one side of the male connector, a male connector center conductor mounted inside the male connector, a female connector center conductor mounted inside the female connector, multiple pins and multiple fixing feet mounted on the lower side of the male connector, the pins corresponding to the male connector center conductor, the fixing feet having a fixing structure at their ends corresponding to the PCB board, and the pins having a soldering structure at their ends corresponding to the PCB board.

[0006] Furthermore, the PCB board has multiple first through slots and multiple second through slots, with the first through slots corresponding to the fixing feet and the second through slots corresponding to the pins.

[0007] Furthermore, the fixing structure includes a limiting sleeve, with the male end of the board and the limiting sleeve located on the upper and lower sides of the PCB board respectively. The limiting sleeve is threadedly engaged with the fixing foot and contacts the PCB board.

[0008] Furthermore, the welding structure includes a welding head located on the underside of the PCB board, and the welding head corresponds to the pin.

[0009] Furthermore, the welding head has a cavity filled with tin blocks, and both the welding head and the tin blocks are in contact with the PCB board.

[0010] Furthermore, the solder block has slots that correspond to the pins, and the solder head is made of a thermally conductive material.

[0011] The beneficial effects of this utility model are:

[0012] 1. Install the male connector center conductor inside the male connector and the female connector center conductor inside the female connector. The male connector is soldered to the PCB board through fixing feet and pins to realize the onboard function. The male connector and the female connector can form a reliable connection through the male connector center conductor and the female connector center conductor.

[0013] 2. A fixing structure is installed at the end of the fixing foot, and a soldering structure is installed at the end of the pin. The fixing structure ensures the stability of the fixing foot, thereby preventing the male connector on the board from shaking during operation and causing poor contact. The soldering structure can be heated for soldering, preventing the soldering iron from directly contacting the PCB board, ensuring the normal use of the PCB board, and preventing excessive solder from melting and overflowing, thus ensuring the success rate of soldering.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a test head terminal, including a male connector 2 mounted on a PCB board 1, a female connector 3 mounted on one side of the male connector 2, a male connector center conductor 5 mounted inside the male connector 2, a female connector center conductor 4 mounted inside the female connector 3, a plurality of pins 6 and a plurality of fixing feet 7 mounted on the lower side of the male connector 2, the pins 6 corresponding to the male connector center conductor 5, the fixing feet 7 having a fixing structure at their ends corresponding to the PCB board 1, and the pins 6 having a welding structure at their ends corresponding to the PCB board 1.

[0023] In this embodiment, the PCB board 1 has a plurality of first through slots 12 and a plurality of second through slots 13. The first through slots 12 correspond to the fixed feet 7, and the second through slots 13 correspond to the pins 6.

[0024] Specifically, the fixing foot 7 is inserted into the first through slot 12 and the pin 6 is inserted into the second through slot 13. The fixing foot 7 can be fixed by the fixing structure to ensure that the male connector 2 of the board end is fixedly connected to the PCB board 1. At the same time, the male connector 2 of the board end is connected to the PCB board 1 through the pin 6. Multiple components can also be soldered on the PCB board 1 to realize the integration of the system.

[0025] The special male connector 2 can be a 4-hole MFK male connector, and the female connector 3 is a corresponding 4-hole female connector; the male connector 2 can also be 1-hole, 2-hole, or other number of holes, and the number of holes in the female connector 3 corresponds to the number of holes in the male connector 2.

[0026] The fixing structure includes a limiting sleeve 8, a male end cap 2 and a limiting sleeve 8 located on the upper and lower sides of the PCB board 1 respectively, the limiting sleeve 8 is threadedly engaged with the fixing foot 7, and the limiting sleeve 8 is in contact with the PCB board 1.

[0027] Specifically, the fixing foot 7 is inserted into the first through slot 12, and then the upper limit sleeve 8 is screwed on so that the upper limit sleeve 8 contacts the PCB board 1, so that the upper and lower sides of the PCB board 1 contact the board end male head 2 and the upper limit sleeve 8 respectively, thus ensuring the fixation of the board end male head 2.

[0028] The welding structure includes a welding head 9, which is located on the underside of the PCB board 1 and corresponds to the pin 6. A cavity is formed inside the welding head 9, and the cavity is filled with a solder block 10. Both the welding head 9 and the solder block 10 are in contact with the PCB board 1. A slot 11 is formed inside the solder block 10, which corresponds to the pin 6. The welding head 9 is made of a thermally conductive material.

[0029] Specifically, pin 6 is inserted into the second through slot 13, and then pin 6 is inserted into the slot 11. The soldering head 9 is heated with a soldering iron, causing the solder block 10 to melt and encapsulate pin 6, thus soldering pin 6 to the PCB board 1. When the male connector 2 needs to be disassembled for repair, heating the soldering head 9 with a soldering iron melts the solder, allowing the soldering head 9 to be directly removed. This allows pin 6 to be pulled out of the second through slot 13.

[0030] Workflow: Insert the fixing foot 7 into the first through slot 12, then tighten the upper limit sleeve 8, then insert the pin 6 into the second through slot 13, then insert the pin 6 into the slot 11, and heat the soldering head 9 with a soldering iron so that the solder block 10 melts and wraps around the pin 6, thereby soldering the pin 6 to the PCB board 1.

[0031] During testing, the male connector 2 is inserted into the female connector 3, so that the center conductor 5 of the male connector is inserted into the center conductor 4 of the female connector, thereby connecting the male connector 2 and the female connector 3 for information transmission.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
