Abstract
The utility model discloses a spring connected electromagnetic shielding connector housing, comprising a plug housing and a socket housing; the plug housing is spliced in the socket housing. The main points are that the plug housing is provided with an annular groove for fixing a spring; the spring is sleeved on the annular groove; the spring is formed by spirally winded wire rods; the socket housing is in close connection with the plug housing through the spring arranged on the plug housing. The spring connected electromagnetic shielding connector housing employs a spring connection shielding mode and has the advantages of a simple structure, small occupation space, reliable shielding, etc.; processes are easy to realize. The technical problems of inconvenient use and bad shielding effects of prior arts are solved.
Description
Technical field the utility model belongs to technical field of electric connectors, relates to the electromagnetic shielding connector shell that a kind of spring connects, thereby realizes the electro-magnetic screen function of connector.
The background technology connector generally is made up of plug, socket, after connector plug, socket plug together, has fit clearance between metal shell, and electromagnetic leakage will be caused in these gaps, and external electromagnetic wave can cause interference to the signal of connector inside through the gap.Therefore the electromagnetic shielding connector requires plug, jack housing can form continuous conductive shield body after plugging together, method commonly used have be threaded, housing installs shielding finger additional, the mode of butt end compression conductive rubber blanket realizes the function of shielding of connector.But all there is certain limitation in these methods, and the plug that is threaded, Socket casing can not realize that straight cutting pulls out, and inconvenient user uses; Install the mode of shielding finger additional, reed structure is complicated, takes up room big and fracture easily; The mode shield effectiveness of butt end compression conductive rubber blanket is poor.Therefore how to realize that a kind of simple and durable, the shielding mode that shield effectiveness is good are particularly important to the development of shielded connector.
The purpose of summary of the invention the utility model is to solve prior art to have the technical problem of using inconvenience, shield effectiveness difference, and the electromagnetic shielding connector shell that provides a kind of spring to connect is to overcome the deficiency of prior art.
The electromagnetic shielding connector shell that the utility model spring connects comprises plug body and jack housing, and said plug body is plugged in the jack housing; Its main points are cannelures that plug body is provided with fixing spring, and spring housing is on said cannelure, and said spring is made up of the wire rod helically coiling, and jack housing closely is connected with plug body through the spring that is arranged on the plug body.
The shielding mode that the utility model adopts spring to connect has simple in structure, and technology realizes that it is little to take up room, and shields advantages such as reliable easily.Solve prior art and had the technical problem of using inconvenience, shield effectiveness difference.
Description of drawings Fig. 1 is the utility model plug body structural representation;
Fig. 2 is the utility model jack housing structural representation;
Fig. 3 is the utility model structural representation.
Among the figure: 1, spring 2, plug body 3, jack housing.
Embodiment is according to Fig. 1, Fig. 2 and Fig. 3, and the electromagnetic shielding connector shell that the utility model spring connects comprises plug body 2 and jack housing 3, and said plug body 2 is plugged in the jack housing 3; Plug body 2 is provided with the cannelure of fixing spring 1, and spring 1 is enclosed within on the said cannelure, and said spring 1 is made up of the wire rod helically coiling, and jack housing 3 closely is connected with plug body 2 through the spring 1 that is arranged on the plug body 2.
Among Fig. 1, shielding spring 1 is by beryllium-bronze silk helically coiling and through Ageing Treatment, and the circle shape is processed in the stranded melting welding in termination of last head and the tail, and this spring has excellent elasticity and toughness, can bear bigger distortion and resilient.During assembling, in the cannelure of the plug body 2 of at first spring 1 support being packed into after big, spring 1 is because in the elastic reaction cannelure that is coated on plug body 2 tightly of self, prevents that spring from deviating from.
Among Fig. 3, when plug body 2 inserted jack housing 3, jack housing 3 was with spring 1 extruding; Spring 1 has elasticity then to the cannelure intramedullary expansion of plug body 2, and spring 1 is compressed between plug body 2 and the jack housing 3 like this, thereby closely contacts with jack housing; Spring becomes the media of plug body and jack housing conducting like this, makes plug body 2 and jack housing 3 conductings, forms continuous conductive shield body; Thereby the realization electro-magnetic screen function obtains lower contact resistance.In addition, the aperture of formation rule seam between spring that is extruded and shell, according to the principle of slit shielding, such structure can obtain good screening effectiveness.
Because spring is formed by the wire rod coiling, the problem that does not exist breach or stress to concentrate, Stability Analysis of Structures intensity is high, and repeatedly extruding can not ruptured.Spring is owing to the design feature of spiral, and very thin silk also can the coiling moulding also can keep certain elasticity and intensity, can satisfy the shielding requirements of metal shell, is beneficial to the microminiaturization development of shielded connector.In addition, spring can adopt the technology manufacturing of electroplating gold on surface then of beryllium-bronze filament winding system, thereby promotes the electric conductivity between shell, obtains higher screening effectiveness.
