Description

Technical Field

[0001] The utility model relates to the technical field of test fixtures, in particular to a connector floating structure and a test fixture. Background Art

[0002] Currently, the floating structures used in test fixtures are mainly connectors with relatively small position installation tolerances or connectors with large guides, so as to make up for the fact that when the connector is inserted into the profiling block of the floating head, the sag angle is not easy to control, resulting in the connector not being insertable during the test or excessive stress when reaching the insertion limit, thus making the quality of the connector uncontrollable.

[0003] In the traditional connector floating structure, due to the small guiding space and wide installation tolerance range, the sag angle of the profiling block of the floating head is large. At the same time, due to the existence of the floating gap, the floating range of the floating head is reduced, and the floating head is not perpendicular to the fixed plate, resulting in a reduced guiding range, thus causing jamming when inserting the connector.

[0004] Therefore, there is an urgent need for a connector floating structure and a test fixture to solve the above problems. Summary of the Utility Model

[0043] As Figures 1 - 5As shown, in this embodiment, the connector floating structure includes a fixed plate 1, a floating head 2, a stop screw 3, an elastic member 5, and a reinforcing rib 6. Among them, the fixed plate 1 is provided with a fixing hole 11. The floating head 2 is disposed on one side of the fixed plate 1. The floating head 2 is provided with a connection hole 222. The stop screw 3 passes through the fixing hole 11 and is connected to the connection hole 222. Along the circumferential direction of the stop screw 3, there is a floating gap 4 between the stop screw 3 and the fixed plate 1. The elastic member 5 is sleeved on the stop screw 3 and is located within the floating gap 4. The two ends of the elastic member 5 are respectively connected to the floating head 2 and the fixed plate 1. The reinforcing rib 6 is installed on the other side of the fixed plate 1. Specifically, a floating head 2 is provided on one side of the fixed plate 1. The floating head 2 is installed and fixed on the fixed plate 1 through the stop screw 3. The stop screw 3 passes through the fixing hole 11 of the fixed plate 1 from the other side of the fixed plate 1 and is connected to the connection hole 222 of the floating head 2, and the stop screw 3 locks the floating head 2. At the same time, there is a floating gap 4 between the stop screw 3 and the fixed plate 1, that is, there is an interval between the outer circumference of the stop screw 3 and the inner circumferential wall of the fixing hole 11 of the fixed plate 1 to ensure the floating of the floating head 2. The elastic member 5 is a profiled spring. The elastic member 5 is sleeved on the stop screw 3, and one end of the elastic member 5 abuts against the step surface 8 of the fixing hole 11 of the fixed plate 1, and the other end abuts against the step surface 8 of the connection hole 222 of the floating head 2, preventing the floating head 2 from sagging, ensuring that the floating head 2 is always perpendicular to the fixed plate 1, enabling the floating head 2 to maintain a vertical state when inserted into the connector, and further enabling a larger guiding range of the floating head 2 and making the insertion into the connector smoother. The reinforcing rib 6 is fixedly installed on the other side of the fixed plate 1 to increase the bearing capacity of the reaction force after the floating head 2 is inserted into the connector.

[0044] Further, with continued reference to Figures 1 - 5 , the connector floating structure further includes a first connecting member. The fixed plate 1 is further provided with an avoidance groove 12. The reinforcing rib 6 is disposed within the avoidance groove 12. The reinforcing rib 6 is provided with a first mounting hole 61.

The reinforcing rib 6 is installed on the fixed plate 1 through the first connecting member, which can achieve quick installation and disassembly, facilitating maintenance and replacement. The reinforcing rib 6 is placed within the avoidance groove 12 of the fixed plate 1, that is, two adjacent side walls of the reinforcing rib 6 abut against two mutually perpendicular side surfaces of the avoidance groove 12, making it not easy to fold, and the reinforcing rib 6 is flush with the end surface of the fixed plate 1, with good aesthetics.

[0045] Further, with continued reference to Figures 1 - 5 , there are two reinforcing ribs 6. The two reinforcing ribs 6 are respectively disposed at both ends of the fixed plate 1, and the two reinforcing ribs 6 are arranged in parallel. After the floating head 2 is inserted into the connector, the two reinforcing ribs 6 disposed at both ends of the fixed plate 1 can increase the bearing capacity of the reaction force after the floating head 2 is inserted into the connector.

[0046] Further, continue to refer to Figures 1 - 5 , the connector floating structure further includes a limiting member 7, and the fixing plate 1 is further provided with a communication hole 13. The limiting member 7 is connected to the fixing plate 1 through the communication hole 13. Specifically, the limiting member 7 includes a limiting portion 71 and a locking portion 72. The limiting portion 71 passes through the communication hole 13, and the locking portion 72 is sleeved on the limiting portion 71 and can abut against the fixing plate 1. After the floating head 2 is inserted into the connector, the limiting portion 71 can abut against the outer shell of the connector to limit the distance between the floating head 2 and the connector. The limiting portion 71 is made of rubber material, with a soft texture, which plays a role in protecting the connector.

[0047] Further, continue to refer to Figures 1 - 5 , the floating head 2 includes a profiling member 21, a floating sleeve 22 and a probe head 23. The floating sleeve 22 is fixed to the fixing plate 1 by a set screw 3.

Specifically, the connector floating structure further includes a second connecting member. The profiling member 21 is provided with a second through hole, and the floating sleeve 22 is provided with a second mounting hole 221. The second connecting member passes through the second through hole and is connected to the second mounting hole 221. The second connecting member is a bolt. The profiling member 21 is installed and fixed on the floating sleeve 22 through the second connecting member. Then, the floating sleeve 22 and the profiling member 21 are fixed to the fixing plate 1 through the probe head 23, which plays a role in guiding and positioning the insertion of the floating head 2 into the connector, ensuring the contact of the probe head 23. Moreover, the floating head 2 can adjust its position relative to the fixing plate 1 according to the connector, ensuring smooth insertion into the connector.

[0048] Further, continue to refer to Figures 1 - 5 , the floating sleeve 22 is provided with a connecting hole 222. The connecting hole 222 has a stepped structure and has a stepped surface 8. A fixing portion 31 is convexly provided on the outer periphery of the set screw 3. Along the axial direction of the set screw 3, the fixing portion 31 can abut against the stepped surface 8 of the connecting hole 222, with a firm connection. Moreover, the tail of the set screw 3 is in threaded cooperation with the connecting hole 222, facilitating the adjustment of the position of the set screw 3 relative to the fixing plate 1 along its axial direction.

[0049] This embodiment also provides a test fixture, including a test bench and the above-mentioned connector floating structure. The connector floating structure is arranged on the test bench. Specifically, an operator places the connector on the sliding mechanism on the test bench. The sliding mechanism pushes the connector to be smoothly inserted by the floating head 2 of the connector floating mechanism. When the floating head 2 just contacts the connector, the floating head 2 makes a floating adjustment according to the position of the connector, ensuring that the connector will not cause its own stress to exceed the controlled range due to excessive force, thereby ensuring the quality of the connector.
