The minimum radial length and the maximum radial length of the third through hole 321 are not the same, and for brevity, the minimum radial length is expressed as a width, and the maximum radial length is expressed as a length. The third through hole 321 may be a strip-shaped hole, such as a waist-shaped hole, an oval-shaped hole, or a combination of a plurality of holes, such as one hole in the length direction and one hole in the width direction. Then, the free end of the rod 52 may pass through the third through hole 321 when the first protrusion 521 faces the length direction of the third through hole 321. When the first projection 521 faces the width direction of the third through hole 321, it cannot pass through the third through hole 321. Under the action of the elastic force of the spring 40, the clamping piece 50 can be clamped or separated by rotating around the axis of the second sleeve 12.

For the reliability of the test procedure, the housing 10 of the probe connector can be detachably and fixedly connected to the casing 71 in the case of being disconnected from the cover 30. That is, in the test, the housing 10 of the probe connector is fixed to the casing 71, and then the spring probe 21 is inserted into the casing 71 from the casing through hole 711 and electrically connected to the test hole 721 of the product PCB 72. Of course, before the housing 10 of the probe connector is fixed to the casing 71, the cover 30 of the probe connector needs to be removed to expose the spring probes 21.

In some embodiments of the present invention, as shown in fig. 3 and 4, the housing 71 further has a mounting hole 712 for fixing the housing 10; the fixing member may pass through the housing 10 and the mounting hole 712 to fix the casing 71 and the housing 10, and the fixing member may be separated from the mounting hole 712 and the housing 10 to detach the casing 71 and the housing 10. Here, the principle of fixing the casing 71 and the housing 10 is the same as the principle of fixing the cover 30 and the housing 10, that is, the fixing is realized by the clamping or releasing of the clamping member 50 in the fixing member, and the mounting hole 712 of the casing 71 is also a strip-shaped hole or an oval-shaped hole similar to the third through hole 321.

Specifically, in an initial state where the outer shell 71 and the housing 10 are not connected, the clip 50 is rotated to a length direction of the first protrusion 521 facing the mounting hole 712, then, a downward pressure is applied on the top seat 51 of the clip 50, and the clip 50 moves downward along the first direction, i.e., moves toward the outer shell 71, until the top seat 51 of the clip 50 abuts against one end of the second sleeve 12 close to the clip 50, at this time, the spring 40 is in a compressed energy storage state, and the first protrusion 521 extends out of the mounting hole 712. Then, the pressing force on the top seat 51 of the clip 50 is continuously maintained, and the clip 50 is rotated to make the first protrusion 521 face the width direction of the mounting hole 712, the pressing force on the top seat 51 of the clip 50 is removed, and the clip 50 moves upward under the elastic force of the spring 40 after being compressed. Since the maximum radial length of the free end is greater than the width of the mounting hole 712, the free end is clamped at the bottom end of the casing 71, and the clamping member 50 is clamped, that is, the casing 10 is clamped on the casing 71 of the product to be tested. If the card connection needs to be disconnected, that is, the probe connector is detached, a downward pressure is applied to the top seat 51 of the card connector 50 to separate the free end from the card connection, the card connector 50 is rotated while the downward pressure on the top seat 51 of the card connector 50 is continuously maintained, the first protrusion 521 faces the length direction of the mounting hole 712, the downward pressure on the top seat 51 of the card connector 50 is removed, and the card connector 50 moves upwards under the elastic force of resilience after the spring 40 is compressed to restore to the initial state. The probe connector is removed from the housing 71 of the product to be tested.

The utility model discloses testing arrangement can reduce the cost, reduce information and reveal and maintain the risk.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
