Abstract
The invention relates to a double-body type case electric connector, which consists of a plug and a socket. The plug comprises a case A, a case B, an insulation base and plug brush type contact elements. The two cases are fixedly connected with each other. The flange of the insulation base is clamped with grooves formed in the case A and the case B. The plug brush type contact elements are arranged in the insulation base. The socket comprises a case, a base and socket brush type contact elements. The plug brush type contact elements and the socket brush type contact elements are uniformly arranged in a staggered manner on the two sides of the plug insulation base and the socket base correspondingly, and an airflow passage is preserved in the middle. A shielding base is arranged outside the plug insulation base. The shielding base surrounds the insulation base. After the engagement of the plug and the socket, the contact elements are positioned within the three-side surrounding of the shielding base. The connector of the invention has the advantages of simple structure, strong electromagnetic shielding effect, effective insulation of electric field and electromagnetic wave interference, and good heat radiation performance, which is applicable to special connector fixing occasions, and has stronger practicability.
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 through 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 receives 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, and 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
The object of the invention mainly is no electromagnetic armouring structure and the relatively poor problem of heat dispersion that exists to 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.
Said double-body type case electric connector; Be made up of plug and socket, plug comprises shell A, shell B, insulating base and plug brush shape contact, and two shells are fixedly connected; Groove among the flange of insulating base and shell A, the shell B fastens, and said plug brush shape contact is installed in the insulating base; Socket comprises shell, pedestal and socket brush shape contact; Said plug brush shape contact and the evenly staggered correspondence of socket brush shape contact are arranged in plug insulating base and socket base both sides; The middle gas channel of reserving, said plug insulating base is provided with the shielding pedestal outward, and the shielding pedestal surrounds insulating base; After connector plug and socket plug together, during three bread that said contact is in the shielding pedestal enclose.
Said shielding pedestal sidepiece is provided with Elastic Teeth.
Said socket brush shape contact is provided with the insulation pillar outward, and the insulation pillar applies high insulating material, fixes through 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 electric field and the Electromagnetic Interference of cage inside and outside 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 instance connector of the present invention is explained further details:
Connector according to the invention is made up of plug and socket; Wherein plug such as Fig. 1 are to shown in Figure 3; Form by plug body A1, plug body B2, shielding pedestal 3, insulating base 4, plug brush shape contact 5, guide finger 6; Said insulating base 4 is enclosed in the shielding pedestal 3, and insulating base and shielding base flange are fastened among shell A1 and the shell B2, and shell A1, 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, socket brush shape contact 10, socket base 11, screw 12; Socket base 11 is fixed on the shell through jack housing 8 steps and screw 12, and pillar 9 passes through press fit with socket brush shape contact 10, and the pillar material is a stainless steel coat film Parylene; Have excellent insulation property and NBC protective performance, pillar 9 and socket brush shape contact cooperate with socket base 11 through the interference mode; Plug and socket brush shape contact is arranged and is characterized as: the evenly staggered susceptor edges that is symmetrically distributed in, and contactless arrangement of obturating plug 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 gets 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 overlapped with jack housing surface 8.2, plug and socket position were fixed, the relative socket stop motion of plug.Since pillar 9 surface-coated Parylene high insulating property material; Guaranteed plug and with the insulation of contact system; After plugging together, because being in three bread of shielding pedestal 3, encloses contact, 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 got into 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 reserving has simultaneously ensured that heat scatters timely and effectively.
