[0002] With the increasing demand for optical communication speed, new requirements have been put forward for the speed of BOSA components (single-fiber bidirectional optical subassembly). High-speed BOSA such as 10G and 25G have been quickly promoted and used in optical communication fields such as 10G, 25G PON, SFP modules, etc. For high-speed BOSA, in order to prevent electrical interference to the greatest extent, the device housing and the LD contact part must be electrically isolated from the system ground (low voltage insulation) is proposed.

[0003] However, most LD housings of BOSA devices on the market currently do not meet this requirement and are only used on TOSA devices; a small number of them use the method of filling insulating material between the device and the module housing, which is not only unreliable but also brings about unstable installation problems.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] Reference Figure 1-Figure 4 As shown, a BOSA adapter with ground isolation includes a first metal part 1, a second metal part 2 is clamped on the first metal part 1, a ceramic pin 4 is inserted on the second metal part 2, and the ceramic pin 4 is made to be inclined at 8° at the end close to the LD (that is, the end away from the first metal part 1), which can effectively reduce the interference of light reflection on the signal. The first metal part 1 and the ceramic pin 4 are tightly matched and press-fitted, and are also tightly matched with the second metal part 2 to complete the overall combination. In addition to being connected to other parts of the device, the head of the first metal part 1 also serves as a connector with an external optical fiber connector, and plays a role in connecting and fixing the external optical fiber;

[0026] The inner hole and chamfered structure of the head of the first metal member 1 can ensure smooth insertion of the external optical fiber connector and good contact between the two optical fibers;

[0027] The outer side of the first metal part 1 is made into a stepped two-section diameter, which is compatible with both FC and SC optical interfaces. The steps are also chamfered to ensure smooth plugging and unplugging of the two interfaces.

[0028] Specifically include:

[0029] The insulating ring 5 is sleeved on the joint between the first metal member 1 and the second metal member 2 to enhance electrical isolation;

[0030] The external card slot of the insulating ring 5 is fixed with the module shell and is made of high-strength engineering plastic. The design adopts an "internal card buckle" structure of "internal card and external glue" and a fixing method combining press-fit adhesive. It has a simple structure and is firmly fixed. It can work normally in an industrial-grade ambient temperature of -40℃ to +85℃.

[0031] Four first snap fasteners 6 are arranged in a circular array on the first metal member 1 and are used for snapping with the insulating ring 5;

[0033] In one embodiment, a ceramic sleeve 3 (with optical fiber) is further provided in the first metal member 1, which mainly serves to connect with the system optical path and can closely cooperate with the ceramic pin 4 of the external optical jumper so that the optical signal can be transmitted efficiently. A tightening opening 31 is provided on the ceramic sleeve 3 to ensure the elasticity of the sleeve and increase the good cooperation with the ceramic pin 4 of the external optical interface.

[0034] In one embodiment, a first movable groove 11 is formed on the first metal member 1, the first buckle member 6 includes a limiting rod 61 located in the first movable groove 11, a limiting spring 62 is disposed at one end of the limiting rod 61 and in the first movable groove 11, and a first limiting hole 51 matching with the limiting rod 61 is formed on the insulating ring 5;

[0035] When the insulating ring 5 is pressed against the first metal part 1, the insulating ring 5 is put on along one end of the first metal part 1. When the insulating ring 5 moves down, it will squeeze the limit rod 61, so that the limit rod 61 slides into the first movable groove 11, and the limit rod 61 compresses the limit spring 62. After the insulating ring 5 is completely pressed in, the limit rod 61 will be inserted into the first limit hole 51 under the elastic force of the limit spring 62 to complete the fixation.

[0036] In one embodiment, the second metal member 2 is provided with a second movable groove 21, the second buckle member 7 includes an elastic plate 71 located in the second movable groove 21, a protrusion 72 is provided at one end of the elastic plate 71, and a second limiting hole 52 matched with the protrusion 72 is provided on the insulating ring 5;

[0037] When the second metal part 2 is assembled with the insulating ring 5, the second metal part 2 is inserted along the gap between the first metal part 1 and the insulating ring 5. At this time, the protrusion 72 is squeezed and deflected toward the second movable groove 21. After being fully inserted into the first metal part 1, the protrusion 72 will be inserted into the second limiting hole 52 under the elastic force of the elastic plate 71.

[0038] In one embodiment, two shielding components are further provided on the insulating ring 5, and the two shielding components are respectively arranged on the outside of the first fastener 6 and the second fastener 7, wherein the shielding component on the first fastener 6 is not shown, and is used to shield the first fastener 6 and the second fastener 7.

[0039] In one embodiment, a slide groove 53 is formed on the insulating ring 5, and the shielding assembly includes a guide rod 54 fixed in the slide groove 53, and an annular baffle 55 is sleeved on the guide rod 54;

[0040] After the assembly is completed, the annular baffle 55 can be pulled downward to move down along the guide rod 54, so that the annular baffle 55 can block the protrusion 72 or the limit rod 61 to protect them and avoid accidental touch.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
