Description

Technical Field

[0001] The utility model relates to the technical field of optical communication device processing, in particular to a transfer fixture for testing. Background Art

[0002] The optical module in the optical communication device is small in size and often needs to be transferred with the help of a tray. The tray currently used has multiple placement slots on it, and the optical communication device is placed in the placement slots. In order to facilitate the removal of the optical module, the diameter of the placement slot is always larger than the diameter of the optical communication device, so it is easy for the optical module to fall during transfer. At the same time, during testing, due to the poor positioning accuracy of the optical module, the optical module needs to be taken out first and then tested, which reduces the test efficiency of the optical module. Utility Model Content

[0003] The utility model provides a test transfer fixture to solve the above-mentioned deficiencies in the prior art and the problems of poor positioning accuracy and poor stability of the optical module after positioning.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A transfer fixture for testing includes a transfer plate, which is a rectangular structure with multiple rows of circular grooves, and multiple perforations are provided at the bottom of the circular grooves. The radius of the circular grooves is greater than the radius of the perforations, wherein the perforations facilitate the insertion of pins, and the bottom of the circular grooves supports the optical module. A pair of limiting plates are provided above the transfer plate, wherein one limiting plate is located above the other limiting plate, and multiple U-shaped grooves are provided on the limiting plate, each U-shaped groove is in a one-to-one correspondence with each row of circular grooves, and the length direction of the U-shaped groove on one limiting plate is perpendicular to the length direction of the U-shaped groove on the other limiting plate. The optical module can be limited by the provided limiting plate, and the X and Y directions of the optical module are limited by the U-shaped grooves during the limiting process, thereby ensuring the accuracy of the limiting process.

[0006] One end of the limiting plate is provided with an end plate, and a limiting rod is passed through the end plate, and the limiting rod is arranged on the side wall of the transfer plate. The limiting plate can be limited by the limiting rod, and then the axial direction of the optical module can be limited by the limiting plate.

[0007] Furthermore, a concave handle is provided on one side of the transfer plate, and the concave handle facilitates the transfer of the transfer plate.

[0008] Furthermore, the intervals between two adjacent circular grooves in each column of circular grooves are equal, which facilitates the testing operation of each optical module.

[0009] The second plane is located inside the first plane, and the outer periphery of the support rod is tangent to the inner wall of the support plate. When the limit plate is inserted, the support rod can act on the second plane, so that the clamping head is clamped in the U-shaped slot, and the end plate and the limit plate are accurately limited, thereby improving the stability after the limit.

[0010] Furthermore, a limiting outer plate is provided on the outer wall of the clamping head, and the limiting outer plate has a limiting effect on the outer side of the end plate to prevent the end plate from being separated from the limiting rod.

[0011] Furthermore, a cut-off groove is provided on the second plane to prevent the end plate from moving outward.

[0012] The advantages of the above technical solution are:

[0013] The utility model facilitates accurate and stable positioning operations of multiple optical modules and facilitates testing operations of the optical modules one by one. BRIEF DESCRIPTION OF THE DRAWINGS
