Description
Technical field
The present invention relates to the electromagnetic armouring structure of a kind of rectangular electric connector.
Background technology
Electromagnetic shielding is one of technical implementation way of suppression electromagnetic interference, and for adapting to the use requirement of modern highly reliable the army and the people's electronic system, electronic devices and components need possess higher anti-electromagnetic interference capability.Wherein the shielding properties of adapter directly affects the laser propagation effect of system signal, and the shielding construction design therefore having electric connector is one of the key factor that connector function realizes.
The shell of general adapter is metal conductive shell, electrical contact portion is fixed on inside metal shell by insulator, electric connector becomes metal enclosed body after plugging together, extraneous low-frequency disturbance can be resisted, but electric connector realizes circuit by when being disconnected to connection, it is necessary to plugged together by the plug and socket of separation；And when realizing circuit by when being switched to disconnect, must be separated with socket by the plug that plug together, therefore the plug of adapter and socket can not become a complete obturator, are the choristas with certain interval, owing to there is gap between housing, reduce the shield effectiveness of housing self.
The cable shield of general adapter and electrical connection between housing be by cable shield being connected on the installation screw of the cable clip at adapter line outlet, the adapter having weather seal to require for the adapter line outlet used in extraneous adverse circumstances, this kind of electrical connection implementation have impact on the sealing of cable and adapter line outlet, adds the risk of seal failure.
Summary of the invention
The technical problem to be solved in the present invention is just to provide the electromagnetic armouring structure of a kind of rectangular electric connector, solves the problem that existing electric connector exists shield effectiveness difference.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions: the electromagnetic armouring structure of a kind of rectangular electric connector, including connector plug housing, Socket casing and screw locking mechanism, it is provided with plug in connector plug housing, socket it is provided with in Socket casing, screw locking mechanism is provided with gasket seal, elastic conduction circle it is provided with between connector plug housing and Socket casing, gasket seal is provided with cable shielding mesh, and gasket seal connects locking cable gauze screen screw on gasket seal.
Preferably, the inner ring of elastic conduction circle is conformed with, prevents coming off of elastic conduction circle.
Preferably, elastic conduction circle shape in wave shape is arranged, the crest that can realize elastic conduction circle contacts with Socket casing respectively at connector plug housing with trough, the contact point that can make elastic conduction circle is distributed in the surrounding of whole adapter, effectively reduce contact resistance, thus reach to electrically connect between plug with socket.
Preferably, the thickness of elastic conduction circle is equal to the thickness of cable shielding mesh, and shield effectiveness is optimal, and simple in construction is easy for installation.
Preferably, gasket seal is provided with the mounting groove of fixing cable shielding mesh, and gasket seal is provided with the screwed hole communicated with mounting groove, and screw is arranged in screwed hole, easy installation and removal, and screw connects reliable, improves shielding properties.
In sum, advantages of the present invention: 1. by screw, cable shield is arranged on gasket seal, make cable shield not need guiding through adapter line outlet and can realize the electrical connection of cable shield and plug, improve the weather seal reliability of cable outlet mouth；
2. the setting of elastic conduction circle, easy to assembly, and mounted configuration is reliable and stable, can realize the electrical connection of plug and socket, improves the shielding properties of adapter；
3. elastic conduction circle and cable shielding mesh overall structure are simple, and Practical Performance is good, effectively achieves the function of shielding of adapter, improves the anti-electromagnetic interference capability of adapter.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the electromagnetic armouring structure of a kind of rectangular electric connector of the present invention；
