Detailed Description

In order to more clearly describe the technical content of the present invention, the following further description is given with reference to specific embodiments.

As shown in fig. 1 to fig. 3c, in this embodiment, an insulating sleeve is sleeved on the exposed metal part 2 of the pluggable optical module 1.

In this embodiment, the insulating sleeve is a silica gel sleeve 3, that is, the insulating sleeve includes an insulating silica gel component.

In this embodiment, the silicone sleeve 3 is in transition fit with the exposed metal part 2 of the pluggable optical module 1. The silica gel sleeve 3 is tightly sleeved on the exposed metal part 2, so that the falling off in the plugging process is avoided.

In this embodiment, the insulating sleeve completely covers the exposed metal part 2 of the pluggable optical module 1.

The silica gel sleeve 3 has elasticity, so that the silica gel sleeve can be applied to various pluggable optical modules with different specifications for electrostatic protection (the size of the protective sleeve can be adjusted according to the actual size of an optical module interface so as to achieve the optimal matching state).

As shown in fig. 1, the width of the side surface of the exposed metal part 2 of the pluggable optical module 1 is 20mm, and the height thereof is 13 mm; the silica gel sleeve 3 is inserted into the exposed metal part 2 of the plug-in optical module 1 according to the arrow direction in the figure. The damage to the plug-in optical module 1 caused by the fact that a human body directly contacts the exposed metal part 2 inserted into the plug-in optical module 1 due to discharge is avoided;

as shown in fig. 2, the front surface of the pluggable optical module 1 has a width of 13mm and a height of 13 mm;

as shown in fig. 3a, the front surface of the silica gel sleeve 3 comprises an outer ring and an inner ring, the outer ring has a width of 14mm and a height of 14mm, and the inner ring has a width of 8mm and a height of 7 mm; as shown in fig. 3b, the width of the side surface of the silica gel sleeve 3 is 20mm, and the height thereof is 13 mm; as shown in fig. 3c, the thickness of the back surface of the silicone sleeve 3 is 1 mm. The size of the silica gel sleeve 3 is matched with the size of the exposed metal part 2 of the plug-in optical module 1, and since the silica gel has certain elasticity, the silica gel can be well wrapped on the exposed metal part 2 of the plug-in optical module 1 to avoid falling off in the plugging process, and the silica gel sleeve 3 can be applied to module electrostatic protection of various specifications.

In the prior art, an exposed metal part in an exposed pluggable optical module 1 is easily interfered by static electricity when an operator plugs and pulls the optical module, so that the whole machine or the optical module is abnormal in local work and even devices are damaged. In the embodiment, an insulating silica gel sleeve 3 is adopted to form an insulating sleeve (namely, an outer insulating anti-static protective sleeve) arranged on an exposed metal part 2 of the pluggable optical module 1, the exposed part is completely wrapped by the insulating layer due to the elasticity of the silica gel, so that the optical module is prevented from being discharged when a human body plugs and unplugs the optical module, the pluggable metal optical module is protected from being damaged by human body static discharge, the static interference resistance of a product is enhanced, the product authentication is smoothly completed by the product, and the normal operation of the optical module and a whole system is protected. The exposed metal part 2 of the optical module is completely covered by the insulating silica gel sleeve 3, so that the electrostatic protection effect on the plug-in optical module is achieved, the optical module is prevented from being invaded by external static electricity, and meanwhile, the insulating silica gel has certain elasticity, can be applied to the electrostatic protection of other modules with different specifications, and ensures the normal operation of the whole machine and an optical module system.

The working principle of the plug-in optical module in the embodiment is as follows:

the outer-layer insulating anti-static protective sleeve made of insulating silica gel and the elasticity of the silica gel are utilized to ensure that the exposed part of the plug-in optical module is completely wrapped by the insulating layer; when an operator inserts and pulls out the optical fiber, the optical module can be prevented from being discharged when the optical module is inserted and pulled out by a human body due to the action of the insulating silica gel protective sleeve, and therefore the optical module and the whole system can be protected from normal operation.

In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
