Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and more specifically, to a fixture compatible with optical module testing and coding. Background Technology

[0002] With the development of networks, from the previous 2G networks to the current 5G networks, the demand for optical modules in data centers will be increasing. Facing the challenges of these product upgrades, we need to meet them in all aspects, the most important of which are price advantages and professional technology.

[0003] In the field of optical communication, products need to be tested and programmed before shipment. If these processes are carried out solely through the PCB board, it will greatly affect production efficiency and increase labor costs. In order to improve efficiency and reduce labor costs, current equipment does not have the capability to perform both testing and programming. Therefore, it is particularly important to design a fixture that is compatible with both optical module testing and programming to ensure multiple compatibility. This will make the fixture cheaper to mass-produce and more interchangeable, thus meeting the needs of the products. Utility Model Content

[0004] The purpose of this invention is to provide a fixture compatible with optical module testing and coding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture compatible with optical module testing and coding, comprising a base located at the bottom of the entire device, on which a first PCB board and an upper board can be mounted, on which a second PCB board is mounted, and a single-headed hexagonal stud is installed between the first PCB board and the second PCB board, with a nut threaded onto the single-headed hexagonal stud, and the first PCB board and the second PCB board are connected to the base via the single-headed hexagonal stud and the nut.

[0006] As a preferred embodiment of this utility model, a third PCB board is mounted on the upper plate. The third PCB board is connected to the upper plate by a second screw. A TYPE C cable head can be inserted into the third PCB board. The TYPE C cable head is sleeved by a pressure strip. The TYPE C cable head and the pressure strip are connected by a third screw.

[0007] As a preferred embodiment of this utility model, a first screw is installed at the bottom of the base, the first PCB board is connected to the base by the first screw, and the upper plate is connected to the base by the first screw.

[0008] As a preferred embodiment of this utility model, a connector socket is installed on the third PCB board, which is compatible with the SFP optical module and is connected by a plug-in method.

[0009] As a preferred embodiment of this utility model, a TYPE C socket is installed on the third PCB board, the TYPE C socket is adapted to the TYPE C cable head, and they are connected by a plug-in method.

[0010] As a preferred technical solution of this utility model, the base is made of bakelite and the upper plate is made of S136 material.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) This utility model is a fixture compatible with optical module testing and coding. The base of this device is made of bakelite, which is relatively soft and does not easily scratch the optical module when inserted. The cost is also low. The larger size makes it convenient to insert and remove the module with a hand pad during operation, avoiding arm pain caused by the arm being suspended in the air. The upper plate is made of S136 material, which adds weight to the module and prevents the fixture from moving due to the friction of insertion and removal during the insertion and removal process, so that it needs to be held down. This makes the device compatible with testing and coding processes and also solves the problem of the fixture moving with the direction of insertion and removal due to the friction of insertion and removal.

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] Example 1

[0022] refer to Figures 1 to 2 Example 1 describes a device including a base 2 located at the bottom of the entire device. A first PCB board 3 and an upper plate 8 can be mounted on the base 2. A second PCB board 5 is mounted on the first PCB board 3. A single-headed hexagonal stud 6 is installed between the first PCB board 3 and the second PCB board 5. A nut 4 is threaded onto the single-headed hexagonal stud 6. The first PCB board 3 and the second PCB board 5 are connected to the base 2 through the single-headed hexagonal stud 6 and the nut 4. A first screw 1 is installed at the bottom of the base 2. The first PCB board 3 is connected to the base 2 through the first screw 1. The upper plate 8 is connected to the base 2 through the first screw 1. A connector socket 15 is mounted on a third PCB board 9. The connector socket 15 is compatible with an SFP optical module and is connected by a plug-in method. The base 2 is made of bakelite material, and the upper plate 8 is made of S136 material.

[0023] In this embodiment, the second PCB board 5 is fixed to the base 2 by a single-headed hexagonal stud 6 and a nut 4. The connection of each interface is completed on the PCB board, and the test setup of the optical module can be completed. The base 2 serves as a test platform for the optical module and can also be used in the optical module coding process. It is compatible with both testing and coding processes and solves the problem of the fixture moving with the insertion and removal direction due to the friction of insertion and removal.

[0024] Example 2

[0025] refer to Figures 3 to 4 Example 2 is a further description of Example 1. It includes a third PCB board 9 mounted on the upper plate 8. The third PCB board 9 is connected to the upper plate 8 by a second screw 11. A TYPE C cable head 12 can be inserted into the third PCB board 9. The TYPE C cable head 12 is sleeved by a pressure strip 13. The TYPE C cable head 12 and the pressure strip 13 are connected by a third screw 14. A TYPE C socket 10 is installed on the third PCB board 9. The TYPE C socket 10 is adapted to the TYPE C cable head 12 and is connected by a plug-in method.

[0026] In this embodiment, the pressure strip 13 is fixed to the upper plate 8 from above by the third screw 14. When coding is required, the SFP optical module is inserted into the connector socket 15 in the third PCB board 9. The upper plate 8 is made of S136 material to increase the weight of the module and prevent the clamp from moving due to the friction of insertion and removal during the insertion and removal process, which would require holding it down.

[0027] In practical applications, the first PCB board 9 is fixed to the base 2 using the first screw 1. The second PCB board 5 is then fixed to the base 2 using a single-headed hexagonal stud 6 and a nut 4. The connections of each interface on the PCB board are then completed, thus completing the optical module test setup. The base 2 serves as a testing platform for the optical module and can also be used during the optical module coding process. The upper board 8 is fixed to the base 2 from the bottom using the first screw 1. The third PCB board 9 is then fixed to the upper board 8 using screws. The TYPE C cable connector 12 is inserted into the TYPE connector on the third PCB board 9. In the C-socket 10, the pressure strip 13 is finally fixed to the upper plate 8 from above by the third screw 14. When coding is required, the SFP optical module is inserted into the connector socket 15 in the third PCB board 9. The base 2 is made of bakelite because the material is soft and does not easily scratch the optical module during insertion. It is also less expensive. Its larger size makes it easier to insert and remove the module with a hand pad during operation, avoiding arm pain caused by the arm being suspended in the air. The upper plate 8 is made of S136 material, which adds weight to the module and prevents the clamp from moving due to the friction of insertion and removal during the insertion and removal process, so that the clamp needs to be held down. This allows the device to be compatible with testing and coding processes and also solves the problem of the clamp moving with the insertion and removal direction due to the friction of insertion and removal.
