Description

Rectangular electric connector
Technical field
The present invention relates to electric connector.
Background technology
The existing a kind of rectangular electric connector that can accomplish power electric current and signal code transmission simultaneously; The power contact and the signal contacting piece that comprise the reed-type of installing in connector shell and the contact installation cavity thereof of rectangle; Like the disclosed a kind of connector of the patent documentation of Chinese patent publication number CN 201549627; It is the flat inserted sheet that Elastic Contact refers to, head is elastic spring that its power contact and signal contacting piece all adopt afterbody; Also have the heat radiation slotted hole in the reed of contact head; This kind contact adopts locking slot thrust cooperation corresponding in the contact installation cavity of turn up shell fragment and the connector outwards routed up of center and tightens together; This kind fixed form causes contact must tool using when unloading to stretch into the inner actuating of the connector shell fragment that turns up, operating difficulties and damage contact easily, and the shell fragment processing more complicated of turning up of contact.
In addition, the electric connector that uses under some occasion need satisfy " hot plug ", and " hot plug " is warm swap; Finger is under the situation of System Backplane charging operation; Extract or insert subsystem, and for a System Backplane of working, subsystem that does not power up is connected to the surge current that backboard produces will cause a very big interference to System Backplane; Destroy the data message of propagating on the System Backplane; Also can make the backboard power supply instantaneous falling occur and cause resetting of system or other functional modules, and will cause the damage of components and parts on the circuit board, this electric current also can permanently damage the pin of electric connector and the track of PCB.And in order to satisfy the requirement that hot plug avoids System Backplane or subsystem to damage simultaneously; Can realize through precharge the subsystem that do not power up; In electric connector field; The precharge connector contact length hierarchical approaches that adopts of subsystem realizes; With a part of contact (as power supply, contact) Design of length become and will grow than the contact (like signal contacting piece) of another part, thereby when the electric connector insertion that is connected with subsystem, power supply, contact at first connect the adaptive electric connector that is connected with backboard the corresponding contact part and to subsystem precharge; And then connect other contact, guaranteeing that the longest contact can connect with last at first breaks off.And but more existing rectangular electric connectors because structure and size thereof have formed fixed mode in the industry, and difficultly realize the length classification of contact, and can't realize hot plug through structural change.
Summary of the invention
The object of the present invention is to provide a kind of rectangular electric connector of being convenient to install unloading power contact.
Technical scheme of the present invention is: a kind of rectangular electric connector; Be provided with in comprising a plurality of contact installation cavitys, front end is the connector shell of the rectangle of inserted terminal; Said contact installation cavity comprises the power contact installation cavity that the top/bottom surface near connector shell is provided with; Power contact installation cavity extends forward from the connector shell rear end to be offered and inserting therein is fixed with the power contact; The front center of said connector shell offers backward and supplies grafting passage that adaptive contact inserts, that communicate in connector shell inside with adjacent power contact installation cavity; Said each power contact installation cavity is near the top/bottom surface of connector shell and on the wall of the chamber of said grafting passage, be integrally formed with the elastic cantilever that extends to the rear end of connector shell; The end of elastic cantilever is provided with the barb towards described grafting passage in the rear end of connector shell; The front end place near connector shell of power contact installation cavity is provided with the front beam that left and right directions extends, and the inner medial surface of power contact installation cavity towards the place of front beam is provided with the thrust convex surface that is used for power contact thrust cooperation; Said power contact comprises the flat substrate at middle part and from substrate respectively forward, one is extended the forward and backward fingertip that is provided with backward; Said back fingertip has a plurality of; Each back fingertip and column distribution also leave the space between adjacent back fingertip, the space between said each back fingertip is in the substrate rear end face and is provided with the groove that is used for locking with the barb of corresponding power contact installation cavity cooperation; Fingertip has that an end is connected with substrate before said, the oblique perk of the other end is on substrate surface and get into the fin part in the said grafting passage; The front end of fin part is connected with the curved sheet part of arc; The front end of curved sheet part tilts to the direction near plane, substrate surface place; The front end of curved sheet part is connected with the oblique sheet part of bending, bends oblique sheet and partly with between the curved sheet part forms the thrust concave surface that cooperates with the thrust surface block of said crossbeam.
Two a pair of being distributed in relatively of described a plurality of contact installation cavity near in the connector housing that connects housing top, bottom surface; Said grafting passage is located between the paired contact installation cavity and connects the connector shell front and back end, and the two paired contact installation cavitys that the grafting passage is adjacent simultaneously communicate.
