This invention discloses one connector, which comprises insulation part, several terminals fixed into insulation part and metal shell with part protection terminal, wherein, the connector has align parts composed of one pair of parallel side walls along long direction of insulation part; the first end wall to connect one end of two sides and the second end wall with different angle to make the connector prevent error plug between to realize similar plug error protection.
Description
[technical field]
The present invention is relevant a kind of electric connector, refers in particular to the electric connector that can be used for electrically connecting two or more electronic installations.
[background technology]
The electric connector that electrically connects two or more electronic installations generally comprises pin connector and the socket connector that cooperatively interacts, and it is installed on respectively on the corresponding electronic installation.Such as, in the personal computer electronic system, except that being provided with main frame, also have various ancillary equipment, like hard disk drive, scanner, CD writer, card reader etc.Along with people's to the miniaturization of personal computer, lightness require constantly high more; Personal computer can not hold all external equipments in the limited space; Therefore the producer is integrated in a part of external equipment on the electronic installation, and the pin connector that installation has the rectangle docking port on this electronic installation is as the total output port of signal.And the socket connector with rectangle docking port that can cooperate with above-mentioned pin connector is installed on the personal computer main frame, cooperate the transmission that realizes signal between main frame and ancillary equipment through socket connector with the pin connector butt joint.Since this kind socket connector and pin connector be directly installed on personal computer and on the electronic installation that will connect; Docking location almost fixed between the two; Even therefore join mutually between the rectangle docking port anti-misplug function is not provided, generally can occur the situation of wrong plug yet.
In some application scenarios, the transmission of the signal of the electronic installation of personal computer and above-mentioned integrated various ancillary equipment also can realize through the grafting of socket connector and cable connector combination.Said socket connector is installed on the personal computer usually, said cable connector combination comprise with personal computer on the pin connector that connects of socket connector and the cable that directly links to each other with electronic installation.This kind cable connector combination can be according to the length of the distance adjustment cable between personal computer and electronic installation; But the pin connector of this cable connector combination with the socket connector docking operation in have bigger randomness; Cause reverse insertion easily; Therefore need docking port that anti-misplug function can be provided, to guarantee the reliability of butt joint.The United States Patent (USP) of bulletin disclosed a pair of cable connector combination and socket connector with anti-mis-insertion structure for the 5th, 199, No. 897 on April 6th, 1993.This cable connector combination has the circuit board of pin connector, cable and attachment plug connector and cable; The insulating body of this pin connector is included in the base portion that longitudinally extends; Hyoplastron that extends forward from base portion and the plurality of terminals conduit of being located at the hyoplastron both sides, some plug terminals are immobilizated in the terminal conduit and extend base portion and be welded on the circuit board.This pin connector also has metal shell, and it comprises the flat part that is immobilizated on the base portion and extend forward and the longitudinal section is the metal frame of isosceles trapezoid from flat part, and said hyoplastron extends in the host cavity that metal frame surrounds.The insulating body of said socket connector comprises base portion and extends the docking section forward from base portion; The longitudinal section of this docking section is isosceles trapezoid and just is housed in the pin connector host cavity; This docking section is provided with the accepting groove that matches with hyoplastron, and accepting groove both sides fixing has some female terminals that electrically contact with plug terminal.When cable connector combination the phase right reverse when inserting socket connector, make cable connector combination to cooperate thereby the short sidewall of pin connector host cavity will stop the long sidewall of socket connector with pin connector.
It is had prevent that pin connector from oppositely inserting the anti-misplug function of socket connector because the longitudinal section of the docking section of above-mentioned plug, socket is isosceles trapezoid, be widely used thereby connect in the electronic installation at cable.Yet along with the continuous development of electric connector, a lot of electric connectors can derive the electric connector of a series of different terminal pitch, different numbers of terminals, and these electric connectors possibly have identical docking port.This time; Though the pin connector of isosceles trapezoid docking port can with dock with it that socket connector is anti-reverse to be mispluged; But but insert in the above-mentioned socket connector, thereby lead to errors cooperation, the damage terminal with a series of equal forwards of pin connector with identical big or small docking port.
Be with, necessary design a kind of not only can with the butt connector anti-mis-insertion, can also with the electric connector of existing rectangle docking port of industry or isosceles trapezoid docking port electric connector anti-mis-insertion.
[summary of the invention]
The object of the present invention is to provide a kind of electric connector with good anti-misplug function.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of electric connector; It comprises insulating body, be immobilizated in the plurality of terminals and the metal shell of partial protection terminal at least in the insulating body, and said electric connector has and docks the docking section that electric connector matches.This docking section has it and comprises a pair of sidewall that is parallel to each other and extends along longitudinally; Connect first end wall of two side one end and connect second end wall of the two side other end, the outside wall surface of first end wall and second end wall is different with the angle of two side angle.
Compared with prior art, electric connector of the present invention has following beneficial effect: be provided with differently through the angle with the angle between the outside wall surface of docking section end walls and sidewall, make electric connector of the present invention have good anti-misplug function.
