Technical field
The present invention relates to technical field of electric connectors.
Background technology
In field of connectors, there is some special field of employment need use the connector of double-body type case usually.Double-body type case is meant that shell is divided into two parts, and fixing back two shells are by mode such as turn over riveting, be threaded in two shells for pedestal, and this structure is particularly suitable for certain shell and needs " straddling " situation at the edge of printed board or mounting panel.
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 advantages such as 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 interchangeability is good, maintainability is strong and be subjected to the welcome of high-end user.
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, increase radome on the electrical connector plug pedestal of double-body type case structure to reach function of shielding, such shielding construction pedestal and radome are at sustained height, its shielding principle is contact contact and effectively almost same time of shielding construction, therefore when docking, contact is subjected to the interference of external electromagnetic source can cause static discharge, thus the signal transmission that influences the electric connector electrical property and influence the internal system miscellaneous part.
In addition, because its high density type spectrum is arranged, the crooked difficulty of product tail end pin is bigger, and bending operation usually causes pin to fracture, and it is extremely low to bend to the formation rate.
Summary of the invention
Purpose of the present invention mainly is effectively to be almost the same time at the contact contact that exists in the present double-body type case Surface Mount electric connector with shielding construction; and the problem of connector tail end bending forming complex procedures and inefficiency, a kind of LRM electric connector of static electrification protective device is provided.
A kind of LRM electric connector of static electrification protective device is made up of plug and socket, and plug is made up of plug body A, plug body B, radome, insulating base A, insulating base B, brush shape contact A, guide finger and printed board; Socket is made up of jack housing, pillar, brush shape contact B, socket base and screw; Described insulating base A, insulating base B are fastened togather by shaggy tooth and are enclosed in the radome, and insulating base A, insulating base B and radome flange are fastened among plug body A and the plug body B; Be provided with brush shape contact A in described insulating base A and the insulating base B, be provided with the shielding pedestal, be provided with Elastic Teeth at shielding pedestal sidepiece at insulating base A and insulating base B outer surface; Described plug body A is fixedlyed connected with plug body B; Described socket base by jack housing step and screw on jack housing; Described pillar passes through press fit with brush shape contact B, cooperates with socket base in the interference mode.
The high insulating material of described pillar surface-coated.
Described radome interface is higher than insulating base A and insulating base B interface.
Described shielding pedestal is a metal material.
Adopt the beneficial effect of technique scheme to be:
That the present invention has is simple in structure, in advance shielding electromagnetic wave disturb, simple, the high characteristics of efficient of contact tail end bending forming operation, be applicable to some special connector stationary applica-tions, have extremely strong practicality.

Embodiment
Be described in further details below in conjunction with the LRM electric connector of above-mentioned accompanying drawing static electrification protective device of the present invention:
A kind of LRM electric connector of static electrification protective device; be made up of plug and socket, as shown in Figure 1, 2, 3: plug is made up of plug body A1, plug body B2, radome 3, insulating base A4, insulating base B5, brush shape contact A6, guide finger 7 and printed board 8.The insulating base A4 of described connector, insulating base B5 are fastened togather by shaggy tooth and are enclosed in the radome 3, insulating base A4, insulating base B5 and radome 3 flanges are fastened among plug body A1 and the plug body B2, plug body A1 and plug body B2 are fixed together, this plug body A and plug body B2 " straddle " at printed board 8 or mounting panel edge, connector plug is connected with printed board 8 takies littler space; Be provided with brush shape contact A6 in described insulating base A4 and the insulating base B5, be provided with the shielding pedestal of metal material at insulating base A4 and insulating base B5 outer surface, and radome 3 interfaces are higher than insulating base A4 and insulating base B5 interface, are provided with Elastic Teeth at shielding pedestal sidepiece; This connector body is as shown in Figure 4: socket is made up of jack housing 9, pillar 10, brush shape contact B11, socket base 12, screw 13, socket base 12 is fixed on the jack housing 9 by jack housing 9 steps and screw 13, pillar 10 passes through press fit with brush shape contact B11, cooperates with socket base 12 in the interference mode.
As shown in Figure 6: plugging together the shielding process in advance is: under the guide effect of guide finger 7, the radome 3 of plug moves to jack housing 9, when radome 3 contacts with jack housing 9, and jack housing 9 conductings; Form the anti-electro-magnetic screen layer of seamless closing, the pillar 10 of socket enters in the pilot hole of insulating base A4, insulating base B5 of plug then, the brush shape contact A6 of plug begins to dock with the brush shape contact B11 of socket, when plug body A surface 14 overlaps with jack housing surface 16, plug and socket position are fixed, the relative socket stop motion of plug.
Because when connector plug enters the socket butt joint, Elastic Teeth is inserted in the jack housing 9, radome 3 plugs together with jack housing 9 earlier, form the anti-electro-magnetic screen layer of seamless closing, the brush shape contact B11 of the brush shape contact A6 of plug and socket plugs together then, because of brush shape contact A6 with formed seamless closing before brush shape contact B11 contact and prevented electro-magnetic screen layer, thereby be subjected to the interference of external electromagnetic source can cause static discharge when having avoided contact to dock.
Shown in Fig. 4,5, because product type spectrum arranging density is bigger, crooked rearward end pin distance is 0.635mm, the bending forming difficulty is big, and injure the tail end contact easily, therefore the plug insulating base is divided into insulating base A4 and insulating base B5, the brush shape contact A6 brush shape contact tail end 15 independent bending formings behind insulating base A4 and the insulating base B5 of packing into, avoided the complicated technology of integral type pedestal brush shape contact two sides bending forming, improve bending forming efficient, improved product qualified rate.
