Abstract
The utility model discloses a kind of electromagnetic sealing gum covers, sealant is set at cable incoming-outgoing equipment, pass through the interference fit of itself and cable outer layer rubber, cable shield and casing, realize the purpose of electromagnetic shielding and waterproof, the center of the seal rubber sleeve is equipped with through-hole, and the middle part of the through-hole is equipped with the step of protrusion.Electromagnetic sealing gum cover structure can also need to be designed to other shapes according to sealing to be rectangular, can meet simultaneously and cable rubber and shielded layer are interference fitted.Electromagnetic sealing gum cover disclosed by the utility model, had not only been able to achieve the seamless seal of electromagnetism, but also can guarantee waterproof performance, improved the Electro Magnetic Compatibility of equipment, improves and realizes percent of pass, shortens the equipment R&D cycle and reduces research and development cost.
Description
Technical field
The utility model relates to power, communication transmission fields, and in particular to a kind of electromagnetic sealing gum cover.
Background technique
EMC Requirements are one mostly important requirement of experiment of current military industry equipment industry, for the electromagnetism for meeting equipment
Compatible performance, research staff often put into very big research and development time and funds in terms of designing with experimental verification.And electromagnetic compatibility
Experiment can't pass, very big factor be due to machine inside electromagnetic noise come out by complete machine cable coupling firing, therefore cable sheet
Body is with very strong shielding properties and equipment good seal can significantly improve the Electro Magnetic Compatibility of complete machine.
Utility model content
The purpose of the present utility model is overcome the deficiencies in the prior art, proposes a kind of electromagnetic sealing gum cover.
The utility model is achieved through the following technical solutions:
A kind of electromagnetic sealing gum cover, the sealant are set at cable incoming-outgoing equipment, pass through itself and cable outer layer glue
The interference fit of skin, cable shield and casing realizes the purpose of electromagnetic shielding and waterproof, which is characterized in that the sealant
The center of set is equipped with through-hole, and the middle part of the through-hole is equipped with the step of protrusion.
A kind of electromagnetic sealing gum cover, which is characterized in that its table is made using electric silica gel in the seal rubber sleeve
Face releases resistance < 1 ohm.
A kind of electromagnetic sealing gum cover, which is characterized in that the seal rubber sleeve structure can be rectangular or other
Shape, subject to casing opening.
A kind of electromagnetic sealing gum cover, which is characterized in that the hardness 50-70 degree of the seal rubber sleeve.
A kind of electromagnetic sealing gum cover, which is characterized in that the seal rubber sleeve and cable outer layer rubber, cable screens

Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention
Specific embodiment of the present utility model.
A kind of electromagnetic sealing gum cover, the sealant are set at cable incoming-outgoing equipment, pass through itself and cable outer layer glue
The interference fit of skin, cable shield and casing realizes the purpose of electromagnetic shielding and waterproof, which is characterized in that the sealant
The center of set is equipped with through-hole (1), and the middle part of the through-hole (1) is equipped with the step (2) of protrusion.
In the present embodiment, a kind of electromagnetic sealing gum cover, which is characterized in that the seal rubber sleeve uses conductive silicon
Glue is made its surface and releases resistance < 1 ohm.
In the present embodiment, a kind of electromagnetic sealing gum cover, which is characterized in that the seal rubber sleeve structure can be
Rectangular or other shapes, subject to casing opening, seal rubber sleeve needs to be had made to order according to the difference of cable thickness, for meeting
Rectangular gum cover and cable can be passed through mould if cable output is sufficiently large by electromagnetic sealing gum cover precise match cable dimension
Molded mode is made of one, and electromagnetic sealing performance is more preferable.
In the present embodiment, a kind of electromagnetic sealing gum cover, which is characterized in that the hardness 50- of the seal rubber sleeve
70 degree.
In the present embodiment, a kind of electromagnetic sealing gum cover, which is characterized in that the seal rubber sleeve and cable outer layer
The Interference size of rubber, cable shield and casing is 0.15-0.25mm, and equipment is coupled to the electricity on cable shielding layer when working
Magnetic noise sound with being introduced directly into casing, has also prevented electromagnetic noise in machine and has been radiated by the gap of cable and casing.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
