Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and more specifically, to a vehicle-mounted optical fiber equipment testing adapter. Background Technology

[0002] A fiber optic adapter is a device used to connect different types of fiber optic interfaces. It can convert between different types of fiber optic interfaces to enable interconnection between different types of network devices. Fiber optic adapters typically include two interface types: fiber optic interface and fiber optic connector. They can convert between different types of fiber optic interfaces to meet the connection needs of different types of network devices.

[0003] Currently, fiber optic products are not used in automotive products, and there are no compatible adapters for automotive-grade fiber optic connectors suitable for testing between testing equipment and products.

[0004] Furthermore, fiber optic adapters come in single-cavity and dual-cavity structures. When there are more diverse requirements, they must be tested separately, and many different sizes of connectors need to be purchased. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a vehicle-mounted fiber optic equipment test adapter. By setting up an assembly design of fiber optic LC connector and fiber optic vehicle-mounted end connector, the test adapter on the fiber optic insertion loss tester can meet the testing requirements of automotive fiber optic connectors.

[0006] To solve the above problems, the present invention adopts the following technical solution: a vehicle-mounted fiber optic equipment testing adapter, comprising a fiber optic LC connector and a fiber optic vehicle-mounted connector. The fiber optic LC connector includes an interface shell, one end of which has an LC interface, and the other end of which has a connecting portion. The connecting portion has a connecting buckle. The interior of the interface shell has a through-hole cavity, and a fiber optic ceramic fixing component is fixedly connected within the cavity. The interface shell has a pin structure. The fiber optic vehicle-mounted connector includes a main shell, one end of which has a plug-in portion, and the other end of which has a guide portion. The interior of the main shell has a through-hole cavity, and the main shell has a plug-in slot corresponding to the connecting buckle. The connecting buckle is engaged and fixed with the plug-in slot. One end of the fiber optic ceramic fixing component is fixed within the cavity, and the other end extends and is fixed within the cavity. The guide portion has a guide structure.

[0007] Furthermore, the pin structure consists of an insertion latch and a limiting latch on the left and right sides of the interface plastic shell. The insertion latch is provided with an insertion block and an insertion connecting plate, and the limiting latch is provided with a limiting block and a limiting baffle.

[0008] Furthermore, the guiding structure consists of a guide buckle and a guide strip disposed on the guiding part.

[0009] A dual-cavity vehicle-mounted fiber optic equipment test adapter includes two of the aforementioned vehicle-mounted fiber optic equipment test adapters, which are connected side by side.

[0010] Furthermore, the two vehicle-mounted fiber optic equipment test adapters are provided with two interface plastic shells and two main body plastic shells, and the two interface plastic shells are respectively snapped and fixed to the two main body plastic shells.

[0011] Furthermore, the insertion snap-fit ​​part of the interface plastic shell is inserted into the limiting snap-fit ​​part of the adjacent interface plastic shell, the insertion snap-fit ​​block of the interface plastic shell abuts against the limiting snap-fit ​​block of the adjacent interface plastic shell, and the insertion connecting plate of the interface plastic shell is snapped and fixed with the limiting baffle of the adjacent interface plastic shell.

[0012] Compared with the prior art, the advantages of this invention are:

[0013] (1) The vehicle-mounted fiber optic equipment test adapter developed in this solution can meet the test requirements of automotive fiber optic connectors by setting up the combination design of fiber optic LC connectors and fiber optic vehicle-mounted connectors.

[0014] (2) In this solution, the interface plastic shell and the main body plastic shell are fixed by the connection buckle and the plug slot, thereby realizing the fixed connection of the fiber optic LC connector and the fiber optic vehicle terminal connector.

[0015] (3) The dual-cavity vehicle-mounted fiber optic equipment test adapter developed in this solution can be set to two when there is a dual-cavity requirement for the vehicle-mounted fiber optic equipment test adapter. The two vehicle-mounted fiber optic equipment test adapters have the same structure and are fixed by side-by-side connection.

[0016] (4) In this scheme, the insertion block of the interface plastic shell abuts against the limiting block of the adjacent interface plastic shell, and the insertion connecting plate of the interface plastic shell is locked and fixed with the limiting baffle of the adjacent interface plastic shell. Through the pin structure design of the two interface plastic shells, the two interface plastic shells are locked and fixed, thereby meeting the requirements of the dual cavity of the adapter.

One end of the fiber optic ceramic fixing component 3 is fixed in the placement cavity 14, and the other end of the fiber optic ceramic fixing component 3 extends and is fixed in the plug-in cavity 24. A guide structure is provided on the guide portion 22.

[0030] The pin structure consists of an insertion latching part 15 and a limiting latching part 18 located on the left and right sides of the interface plastic shell 1. The insertion latching part 15 is provided with an insertion latching block 16 and an insertion connecting plate 17, and the limiting latching part 18 is provided with a fixing limiting latching block 19 and a limiting baffle 20.
