Description

Technical Field

[0001] The utility model relates to the technical field of crystal head testing, in particular to a crystal head shrapnel height testing device. Background Art

[0002] Typically, a RJ45 connector has a spring that tilts upward. To remove the RJ45 connector from the network port, you need to press the spring to release it. Before the RJ45 connector leaves the factory, it undergoes a tilt height test. If the tilt height fails to meet the specified test, its service life will be significantly reduced. This means that the spring loses its elasticity before the design standard is reached, preventing it from returning to its tilted position.

[0003] Currently, workers mainly rely on manual measurement with calipers to complete the detection of the spring lift height before leaving the factory. Not only is the detection efficiency low, but the reading error is large and the detection accuracy is also poor.

[0004] Therefore, it is necessary to develop a crystal head shrapnel height testing device to realize the mechanized detection of the shrapnel tilting height, thereby improving the detection efficiency and detection accuracy.

[0005] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0019] Wherein, the object distance sensor is installed on the lifting plate.

[0020] Optionally, the linear drive mechanism includes:

[0021] vertical track;

[0022] A longitudinal slide, one side of which is connected to the vertical track for vertical sliding, and the other side of which is connected to the lifting plate;

[0030] The beneficial effect of the utility model is that it provides a crystal head spring piece height testing device. When it is necessary to test the spring piece height of the crystal head, the fixture cover is first lifted upward, and then the crystal head is inserted into the test socket; then, the object distance sensor downward obtains the distance dimension from the object distance sensor to the spring piece. If the distance dimension is within the allowable value range, it means that the spring piece height is qualified; otherwise, if the distance dimension is outside the allowable value range, it means that the spring piece height is unqualified.

[0051] The fixture base 1 is provided with a test socket for inserting the crystal head 100. The fixture cover 2 is disposed above the fixture base 1 and is used to cooperate with the fixture base 1 to press the crystal head 100; wherein, the fixture cover 2 is provided with an avoidance notch 201 at a position corresponding to the spring clip 100a of the crystal head 100, so that the spring clip 100a is exposed on the fixture cover 2. The height adjustment bracket 3 extends above the avoidance notch 201. The object distance sensor 4 is mounted on the height adjustment bracket 3 and is located above the avoidance notch 201, and is used to detect the distance between the object distance sensor 4 and the spring clip 100a.

[0052] The lower end of the vertical guide rod 5 is fixed to the jig base 1, and the jig cover 2 is slidably connected to the vertical guide rod 5. The compression spring is mounted on the vertical guide rod 5 and located above the jig cover 2, and is used to drive the jig cover 2 to slide downward to compress the crystal head 100.

[0053] In a normal state, the compression spring drives the jig cover plate 2 to slide downward to be attached to the jig base 1, so before the crystal head 100 is loaded, the jig cover plate 2 needs to be pulled upward to overcome the elastic force of the compression spring; after the crystal head 100 is inserted into the test plug, the jig cover plate 2 is released, and the compression spring automatically drives the jig cover plate 2 to move downward, thereby compressing the crystal head 100.

[0054] The crystal head 100 spring piece 100a height testing device provided by the embodiment can realize the mechanized detection of the spring piece 100a lifting height, thereby improving the detection efficiency and the detection accuracy.
