Description

TECHNICAL FIELD

[0001] The utility model belongs to module type distribution frame uses distribution module technical field, concretely relates to a kind of indoor module type distribution frame uses distribution shell. BACKGROUND

[0002] In the data center, machine room and other wiring-intensive scenarios, the physical interface of the wiring module is exposed to the open environment for a long time, and metal particles, fiber dust and oil stains in the air will gradually deposit on the surface of the port conductive contact. These pollutants may form a conductive film layer under the action of a humid environment, causing signal transmission attenuation, abnormal increase of contact resistance and other hidden faults, especially in high-frequency signal transmission scenarios, micron-level pollutants can cause eye diagram quality degradation. Although the traditional dust plug achieves basic protection through physical barrier, its independent design has inherent defects: the operator needs to perform dust plug taking and placing action every time the cable is plugged in and out, which not only increases the complexity of the work process, but also causes the dust plug to fall off between the gaps of the equipment, making it difficult to manage the scattered parts in the maintenance site, and in some scenarios, the dust plug is mistakenly inserted into other device ports, causing short circuit accidents.

[0003] From the perspective of engineering practice, the systemic defects of existing protection schemes are more prominent. The dust plug needs to be strictly matched with the port specification, and the interface size tolerance of different manufacturers' equipment leads to inconsistent sealing performance of universal dust plugs, with actual dust prevention efficiency fluctuating in the range of 30%-70%. In a dynamic environment requiring high-frequency maintenance, repeated disassembly and assembly of the dust plug can accelerate the metal fatigue of the port spring piece, and the plastic material is prone to aging and brittleness under long-term ultraviolet radiation, which increases the risk of physical damage to the port. More importantly, the management of scattered dust prevention components requires special storage devices, which means additional space occupation and inventory management costs in medium and large machine room scenarios. When the loss rate of dust plugs exceeds 15%, the comprehensive maintenance cost will exceed the fault repair cost of the port itself, and this technical inversion phenomenon has become a key bottleneck restricting the reliability of the wiring system.
