[0030] The following will further describe the present application in detail Figures 1-5 with reference to the accompanying drawings.

[0031] The embodiment of the present application discloses an SMP connector inspection tooling.

[0032] An SMP connector inspection tooling includes a base 1, a cover plate 2, a positioning member 3, and a connecting member 4. The cover plate 2 is detachably mounted on the top of the base 1 through the connecting member 4. During the assembly process of the cover plate 2 and the base 1, the base 1 and the cover plate 2 are positioned by the positioning member 3.

[0033] A plurality of placement slots 11 are formed on one side of the base 1 close to the cover plate 2. The inner wall of each placement slot 11 is arranged in a stepped shape along the direction from close to the cover plate 2 to far from the cover plate 2, and the diameter of the inner wall of the placement slot 11 gradually decreases along the direction from close to the cover plate 2 to far from the cover plate 2. In the embodiment of the present application, each placement slot 11 is arranged in a T shape.

[0034] When placing the SMP connector 5, insert a part of the SMP connector 5 inside the placement groove 11, position the SMP connector 5 through the inner wall of the placement groove 11, and support the SMP connector 5 through the top of the groove wall of the placement groove 11, so as to improve the placement stability of the SMP connector 5.

[0035] In order to facilitate the removal of the SMP connector 5 from the inner wall of the placement groove 11, a clamping groove 12 is provided at the top position of the inner side wall of the placement groove 11. The clamping groove 12 penetrates through the top of the base 1, and the clamping groove 12 and the placement groove 11 are coaxial.

[0036] After the SMP connector 5 is placed at the placement groove 11, the bottom position of the inner wall of the clamping groove 12 is lower than the top position of the SMP connector 5.

[0037] When it is necessary to remove the SMP connector 5 from the placement groove 11, the inspector uses tweezers to remove the SMP connector 5 from the placement groove 11 by using the height difference between the bottom of the inner wall of the clamping groove 12 and the top of the SMP connector 5, so as to improve the convenience of removing the SMP connector 5 from the placement groove 11.

[0038] The cover plate 2 and the inner wall of the placement groove 11 form an observation cavity. The SMP connector 5 is placed inside the observation cavity. In order to facilitate the observation of the SMP connector 5 inside the observation cavity, the cavity wall of the observation cavity is made transparent. In the embodiment of the present application, both the base 1 and the cover plate 2 are made of transparent acrylic plate material.

[0039] When observing the top of the SMP connector 5 located inside the observation cavity, place the cover plate 2 above the base 1, and make the SMP connector 5 to be inspected close to the microscope. Detect the crack on the top of the SMP connector 5 through the microscope, and mark the position on the cover plate 2 close to the unqualified SMP connector 5 with a marker pen.

[0040] When observing the bottom of the SMP connector 5 located inside the observation cavity, turn the cover plate 2 and the base 1 as a whole, so that the base 1 is located above the cover plate 2, and make the SMP connector 5 to be inspected close to the microscope. Detect the crack on the bottom of the SMP connector 5 through the microscope, and mark the position on the base 1 close to the unqualified SMP connector 5 with a marker pen.

[0041] Then, transfer the unqualified mark on the cover plate 2 to the base 1 radially, so as to lock all unqualified SMP connectors 5, and directly take out all unqualified SMP connectors 5.

[0042] The positioning member 3 is used to reduce the possibility of misalignment of the relative positions of the cover plate 2 and the base 1 in the assembled state. A plurality of positioning holes 13 are provided on one side of the base 1 close to the cover plate 2. The positioning member 3 includes a plurality of positioning pins fixedly installed on one side of the cover plate 2 close to the base 1. The plurality of positioning pins are all perpendicular to the cover plate 2, and each positioning pin is inserted and matched with the corresponding positioning hole 13.

[0043] By using the positioning member 3, the possibility of misalignment between the cover plate 2 and the base 1 is reduced. Furthermore, the possibility of misalignment when marking the position of the unqualified SMP connector 5 with a marker pen is reduced.

[0044] The connecting member 4 is used to make the distance between the base 1 and the cover plate 2 in the assembled state less than the length of the SMP connector 5. When the cover plate 2 and the base 1 are turned over as a whole, the SMP connector 5 will fall onto the cover plate 2 under the action of gravity, and the cover plate 2 supports the SMP connector 5.

[0045] At this time, since the distance between the base 1 and the cover plate 2 in the assembled state is less than the length of the SMP connector 5, furthermore, the possibility of damage to the SMP connector 5 caused by the SMP connector 5 falling out of the cover plate 2 and the base 1 is reduced.

[0046] A plurality of first connecting holes 14 are provided on the base 1, and a plurality of second connecting holes 21 are provided on the cover plate 2. The connecting member 4 includes a plurality of connecting screws, and the first connecting holes 14, the second connecting holes 21, and the connecting screws correspond to each other one by one. The connecting screw passes through the second connecting hole 21, and the connecting screw is threadedly connected to the first connecting hole 14.

[0047] When assembling the cover plate 2 and the base 1, just pass the connecting screw through the second connecting hole 21 and thread the connecting screw to the first connecting hole 14. This is used to improve the convenience of connecting the cover plate 2 and the base 1.

[0048] The implementation principle of an SMP connector inspection tooling according to an embodiment of the present application is as follows: When placing the SMP connector 5, the SMP connectors 5 are placed in batches inside the observation cavity. Then, the positioning pins on the cover plate 2 are inserted into the corresponding positioning holes 13 on the base 1, and the cover plate 2 and the base 1 are fixed by connecting screws.

[0049] When observing the top of the SMP connector 5, the cover plate 2 is located above the base 1, and the SMP connector 5 is moved in the direction close to the microscope. The cracks on the top of the SMP connector 5 are detected by the microscope, and a marker pen is used to mark the position on the cover plate 2 close to the unqualified SMP connector 5.

[0050] When observing the bottom of the SMP connector 5, place the cover plate 2 under the base 1 and move the SMP connector 5 in the direction closer to the microscope. Detect cracks in the bottom of the SMP connector 5 through the microscope and mark the position on the base 1 close to the unqualified SMP connector 5 with a marker pen.

[0051] Then, mirror the marks on the cover plate 2 onto the base 1 to lock all unqualified SMP connectors 5.

[0052] Then, rotate the connecting screw to disconnect the connection between the cover plate 2 and the base 1, allowing the inspector to remove the SMP connector 5 with tweezers. After removing the unqualified SMP connectors 5, transfer the qualified SMP connectors 5 to the next process.

[0053] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
