Description
Technical field
The present invention relates to a kind of electric connector, especially a kind of double-body type case electric connector with quick heat radiating and function of shielding.
Background technology
In field of connectors, the connector of double-body type case need be used in some special field of employment.Double-body type case is meant that shell is divided into two parts, and pedestal is fixed in two shells back two shells, and mode connects by turning over riveting, be threaded etc.
The electric connector of current double-body type case extensively applies to each field.LRM (Line Replaceable Module) the series of modular electric connector of releasing with Amphenol Co., Ltd is that the double-body type case electric connector of representative is widely used in the high-end fields such as space flight, aviation, electronic module, communication, and this type electric connector is subjected to the welcome of high-end user because of advantages such as interchangeability are good, maintainability is strong.
But along with the development of electronic information technology in recent years, the complete transmission of information has become the primary direction that high terminal adapter development is considered, the electric connector of double-body type case structure, its plug body is with screw thread or turn over riveting locking, shell itself is not because of there being good continuity, influenced its capability of electromagnetic shielding, and such connector do not have the electromagnetic armouring structure of other form again, cause the possibility of this connector information dropout, distortion to increase.
In addition, the electric connector of miniaturization, densification uses increasing in the confined space, along with increasing of contact core number, the heat that produces in the signal transduction process is also more and more, can't dispel the heat at short notice and will bring huge destruction to electric connector and whole communication system.
Summary of the invention
Purpose of the present invention mainly is no electromagnetic armouring structure and the relatively poor problem of heat dispersion that exists at present double-body type case electric connector, and a kind of double-body type case electric connector with quick heat radiating and function of shielding is provided.
Described double-body type case electric connector is made up of plug and socket, and plug comprises shell A, shell B, insulating base and contact, and two shells are fixedly connected, and the groove among the flange of insulating base and shell A, the shell B fastens, and contact is installed in the insulating base; Socket comprises shell, pedestal and contact, and the plug insulating base is provided with the shielding pedestal outward, and this shielding pedestal surrounds insulating base and forms the Ferrari basket structure, and contact evenly is staggered in the pedestal both sides, the middle gas channel of reserving.
Described shielding pedestal sidepiece is provided with Elastic Teeth.
Described socket contact is provided with the insulation pillar outward, and the insulation pillar applies high insulating material, fixes by interference fit and pedestal.
Adopt the connector of the present invention of said structure scheme have simple in structure, capability of electromagnetic shielding strong, can completely cut off the electric field of cage inside and outside and Electromagnetic Interference effectively, the advantage of perfect heat-dissipating, be applicable to the special connector stationary applica-tions, have stronger practicality.

Embodiment
Below in conjunction with above-mentioned accompanying drawing example connector of the present invention is described in further details:
Connector of the present invention is made up of plug and socket, wherein plug as shown in Figure 1 to Figure 3, form by plug body A 1, plug body B 2, shielding pedestal 3, insulating base 4, brush shape contact 5, guide finger 6, described insulating base 4 is enclosed in the shielding pedestal 3, insulating base and shielding base flange are fastened among shell A 1 and the shell B2, shell A 1, shell B2 are fixed together, shell A, shell B " straddle " at printed board 7 or mounting panel edge, connector plug is connected with printed board takies littler space; Connector body such as Fig. 4 are to shown in Figure 5, form by jack housing 8, pillar 9, brush shape contact 10, socket base 11, screw 12, socket base 11 is fixed on the shell by jack housing 8 steps and screw 12, pillar 9 passes through press fit with brush shape contact, the pillar material is a stainless steel coat film Parylene, have excellent insulation property and NBC protective performance, pillar 9 and brush shape contact cooperate with socket base 11 by the interference mode; The plug and socket contact is arranged and is characterized as: the evenly staggered susceptor edges that is symmetrically distributed in, and contactless arrangement of pedestal central authorities is reserved as the air blast gas channel, thus heat radiation faster and better.
This connector plugs together the shielding process: under the guide effect of guide finger 6, plug shielding pedestal 11 is to jack housing 8 motions, when shielding pedestal tooth body 3.1 contacts with jack housing inner surface 8.2, shield pedestal tooth body 3.1 and begin to take place elastic deformation, and with jack housing 8 conductings; Simultaneously, socket pillar 9 enters in the pilot hole of plug shielding pedestal 3 and insulating base 4, plug brush shape contact 5 begins to plug together with socket brush shape contact 10, when plug body A surface 1.1 overlaps with jack housing surface 8.2, plug and socket position are fixed, the relative socket stop motion of plug.Owing to protect
Manage 9 surface-coated Parylene high insulating property material, guaranteed plug and with the insulation of contact system, after plugging together, because contact is in three bread of shielding pedestal 3 and encloses, formed " Ferrari cage " structure, the electric field and the Electromagnetic Interference that completely cut off the cage inside and outside effectively, thus other signals that guarantee are to the interference of contact system.
When connector plug entered the socket butt joint, Elastic Teeth was inserted in the jack housing, formed the anti-electro-magnetic screen layer of seamless closing, and the air blast heat dissipation channel of Yu Liuing has ensured that heat scatters timely and effectively simultaneously.
