[0001] This utility model relates to the field of positioning fixture technology, specifically a positioning fixture for connector terminal testing. Background Technology

[0002] In the connector manufacturing industry, parameters such as terminal dimensional accuracy and coplanarity are key indicators determining the reliability of electrical connections. Therefore, specialized positioning fixtures must be used during the production process to perform 100% inspection of the terminals. Existing positioning fixtures have complex structures and unreasonable designs. Furthermore, the positioning grooves on the fixtures that directly contact the terminals are vulnerable parts. During frequent handling and testing, they gradually wear down and deform due to friction and collisions. Once the wear exceeds the tolerance range, it will lead to inaccurate testing. To address this problem, the inventors designed a positioning fixture for connector terminal testing. Utility Model Content

[0019] The positioning plate 21 is designed as a modular part that can be quickly replaced. The positioning groove 22 is shaped to match the connector terminal to be tested. Its purpose is to precisely hold the terminal. The connecting block 31 is fixed at the four corners of the lower surface of the positioning plate 21. Its purpose is to cooperate with the connecting hole 15 on the base 11 as a primary guide and error prevention device during the installation of the positioning plate 21. The connecting post 32 is the core transmission component for connection and locking force. The positioning hole 33 is used to accommodate the fixing tube 34 and the fixing block 36. It is the mounting cavity of the locking mechanism. The positioning plate 21 can be locked and released by rotating the threaded post 35.

[0020] A fixing tube 34 is fixed inside the positioning hole 33, and the fixing tube 34 is threadedly connected to the threaded post 35.

[0021] The fixed tube 34 is a robust threaded female seat for the threaded post 35 to rotate inside it.

[0022] A fixing block 36 is fixed to the surface of the threaded post 35 away from the connecting post 32. A guide groove 37 is provided inside the fixing block 36. The guide groove 37 is in the shape of a cross. The fixing block 36 is located inside the positioning hole 33.

[0023] The fixing block 36 effectively transmits the rotational force from the tool to the threaded post 35, and the guide groove 37 is used to cooperate with the Phillips screwdriver head to facilitate the application of force and rotation.

[0024] Limiting holes 38 are provided inside the connecting column 32 and the base 11. The diameter of the limiting hole 38 is smaller than the diameter of the positioning hole 33. The end of the threaded column 35 away from the fixing block 36 is located inside the limiting hole 38.

[0025] The limiting hole 38 is used to radially limit the end of the threaded post 35.

[0026] The base 11 has a connecting groove 12 and a mounting groove 14 in the middle. The depth of the mounting groove 14 is greater than the depth of the connecting groove 12. The positioning plate 21 is located inside the mounting groove 14.

[0027] The connecting groove 12 is used to place and initially limit the connector terminal itself to be tested, and the mounting groove 14 is used to precisely accommodate and limit the positioning plate 21.

[0028] A limiting groove 13 is provided on one side of the base 11, and mounting holes 17 are provided inside both sides of the base 11.

[0029] The limiting groove 13 provides unobstructed vision or operating space for equipment such as visual inspection or laser marking, and the mounting hole 17 is used to firmly fix the entire fixture to the inspection platform or workbench with screws to ensure stability during the inspection process.

[0030] The base 11 has connecting holes 15 and fixing holes 16 inside.

The fixing hole 16 is used to accommodate the connecting post 32, which is the main positioning and locking channel of the positioning plate 21 in the vertical direction.

[0032] Working principle: When it is necessary to test the connector terminal, first pass the screw through the mounting hole 17 and fix the base 11 in the required position. Then place the terminal inside the connection groove 12. With the design of the positioning groove 22, the terminal can be stably placed inside the base 11. Then, the testing mechanism can be used to test the terminal. With the design of the limiting groove 13, the terminal can be marked and tested without obstruction.

[0033] When the positioning groove 22 deforms, insert a screwdriver into the guide groove 37 and apply a rotational force to the fixing block 36, causing the threaded post 35 to rotate inside the fixing tube 34. After one end of the threaded post 35 disengages from the limiting hole 38, apply an upward pulling force to the positioning plate 21, causing the connecting post 32 to disengage from the fixing hole 16. Then, place the new positioning plate 21 on top of the mounting groove 14 and apply a downward pressing force to the positioning plate 21, causing the connecting block 31 to insert into the connecting hole 15 and the connecting post 32 to insert into the fixing hole 16. Subsequently, apply a rotational force to the fixing block 36, causing the threaded post 35 to pass through the interior of the connecting post 32, and the fixing block 36 to retract into the positioning hole 33.
