Abstract
The utility model is related to a kind of waterproof shield protection caps using conductive plastics; including lid and washer; it is connected by connect band between the lid and washer; the lid lower end is provided with inner cavity; it is located in the lid above inner cavity and sheet metal is installed, the lid, washer and connect band is all made of conductive plastics and is made.Conductive plastics uses a kind of special plastics, is mixed with carbon dust, electrically conductive.The washer of the utility model is mounted between socket and casing, casing is ground connection, the exposure of socket is covered on the inside by lid, a piece of copper sheet is installed inside lid, lid serves as shielding case by electromagnetic interference packet inside, plays the role of shielding, is made since lid, washer and connect band are all made of conductive plastics, therefore the exposure of socket short circuit over the ground can be realized excretion.
Description
Technical field
The utility model is related to the protective devices of a kind of electronic equipment connector, and conductive plastics is used more particularly to a kind of
Waterproof shield protection cap.
Background technology
For the socket of electronic device connector, its jack is exposed at outside mostly, and also part is only simple covers
A protection cap plays the function of dust-proof water-inlet-proof, the problem of ignoring in terms of EMI (electromagnetic interference) and EMC (Electro Magnetic Compatibility).
Electromagnetic interference refers to any electromagnet phenomenon that can make equipment or system performance degradation.Electro Magnetic Compatibility refers to equipment or system at it
The operation that meets the requirements in electromagnetic environment does not generate any equipment in its environment the ability of intolerable electromagnetic interference.Suddenly
The problem of in terms of slightly EMI and EMC, the performance issue of equipment of itself or neighbouring other equipment may be will have a direct impact on.
Invention content
The technical problem to be solved by the utility model is to provide a kind of waterproof shield protection cap using conductive plastics, lids
Son serves as shielding case by electromagnetic interference packet inside, plays the role of shielding, since lid, washer and connect band are all made of conduction
Plastics are made, therefore can the exposure of socket short circuit over the ground be realized excretion.
Technical solution adopted by the utility model to solve its technical problems is：A kind of waterproof using conductive plastics is provided
Shielding protection lid, including lid and washer, are connected between the lid and washer by connect band, which is provided with
Inner cavity, the interior inner cavity top that is located at of the lid are equipped with sheet metal, and the lid, washer and connect band are all made of conductive modeling
Material is made.Conductive plastics uses a kind of special plastics, is mixed with carbon dust, electrically conductive.
As a kind of supplement to technical solution described in the utility model, the lid side passes through connect band and pad
Circle is connected, which is provided with horizontal extension.Extension provides the place that a human hand is pinched, and facilitates and beats lid
It opens.
As a kind of supplement to technical solution described in the utility model, circle protrusion is disposed in the middle part of the inner cavity
Portion.When inner cavity is sleeved on socket, lug boss plays the role of compressing limit so that socket is not easily separate with lid.
As a kind of supplement to technical solution described in the utility model, the sheet metal uses copper sheet.
As a kind of supplement to technical solution described in the utility model, the inner cavity lower ending opening to lug boss
Inner wall is in big top and small bottom coniform.Lid is facilitated to cover on socket.
Advantageous effect：The utility model is related to a kind of waterproof shield protection cap using conductive plastics, washer is mounted in
Between socket and casing, casing is ground connection, and the exposure of socket is covered on the inside, a piece of copper is equipped with inside lid by lid
Piece, lid serve as shielding case by electromagnetic interference packet inside, play the role of shielding, since lid, washer and connect band are adopted
It is made of conductive plastics, therefore the exposure of socket short circuit over the ground can be realized excretion.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Diagram：1, sheet metal, 2, lid, 3, washer, 4, connect band, 5, lug boss, 6, inner cavity, 7, extension.
Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiment of the utility model is related to a kind of waterproof shield protection cap using conductive plastics, as shown in Figure 1, packet
Lid 2 and washer 3 are included, is connected by connect band 4 between the lid 2 and washer 3, which is provided with inner cavity 6,
It is located at 6 top of inner cavity in the lid 2 and sheet metal 1 is installed, the lid 2, washer 3 and connect band 4 is all made of conduction
Plastics are made.
2 side of lid is connected by connect band 4 with washer 3, which is provided with horizontal extension
7。
6 middle part of inner cavity is disposed with a circle lug boss 5.
The sheet metal 1 uses copper sheet.
6 lower ending opening of inner cavity to lug boss 5 inner wall in big top and small bottom coniform.
Embodiment
Electric current flows through socket and just will produce magnetic field, and magnetic field can interfere neighbouring equipment or the performance of equipment of itself.Pad
Circle 3 is mounted between socket and casing, and casing is ground connection, and the exposure of socket is covered on the inside by lid 2, in lid 2
Face is equipped with a piece of copper sheet, and lid 2 serves as shielding case by electromagnetic interference packet inside, plays the role of shielding, due to lid 2,
Washer 3 and connect band 4 are all made of conductive plastics and are made, therefore can short circuit, sheet metal 1 absorb electricity over the ground by the exposure of socket
Then magnetic wave is excreted to ground, according to the conservation of energy, need high toward low diffusion.
