Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers in particular to a kind of electric connector that improves its assembling stability.

[background technology]

Along with the development of electronic product precise treatment more and more, element on the computer motherboard is precise treatment more and more also, so just make electric connector that one of element is used for fixing the chip module also towards the trend development of precise treatment, so that described chip module is with carrying out the excellent electrical property conducting between the circuit board.

The development of the precise treatment of electric connector certainly will its combination part such as the terminal of insulating body and Qi Nei all develop towards precise treatment, and the precise treatment development generally is under the situation of part smaller volume, structure becomes simply, but does not influence the purpose that electrically conducts, and promptly will take into account in all directions.Existing a kind of electric connector, it comprises an insulating body, run through in the described insulating body and be provided with most accepting grooves, the madial wall of described accepting groove has a projection, the same described madial wall of described projection forms certain bit space, most terminals correspondence respectively are fixedly arranged in most described accepting grooves, each described terminal has a base portion respectively, described base portion is positioned at space, described location to limit the displacement of described terminal horizontal direction, extended upward an adjutage from described base portion, and by a side of described adjutage, extend upward a strip connecting portion from described base portion, be extended with a weld part downwards from described base portion, in addition, described accepting groove bottom also is provided with a limiting section near described weld part place, makes that in order to locate described weld part the displacement of described terminal vertical direction is limited.

Though above-mentioned electric connector can reach described terminal and be fixed in the interior purpose of described insulating body, there are following many disappearances:

1. described terminal only is to rely on described base portion to be positioned at space, described location it is positioned in the horizontal direction, in the vertical direction only is to rely on described limiting section that it is positioned, because described terminal need often be crimped, so occur the phenomenon of rocking easily.

2. described terminal only is provided with a described strip connecting portion, like this its on processing procedure, during as operations such as punching press, bendings as described in the easy torsional deformation of terminal, promptly can not carry out good location to described terminal, make processing procedure more stable.

Therefore, be necessary to design a kind of new electric connector, to overcome above-mentioned disappearance.

[utility model content]

Creation purpose of the present utility model is to provide a kind of and utilizes terminal that the double material strips structure is set to make that its assembling stability is stronger, and the more stable electric connector of terminal processing procedure.

In order to achieve the above object, the utility model electric connector adopts following technical scheme:

A kind of electric connector, it comprises an insulating body, runs through in it to be provided with most accepting grooves; Most terminals, each described terminal has a base portion that is located in the described accepting groove respectively, extended upward an adjutage from described base portion, and the both sides in described adjutage extend upward the material portion of company that is provided with respectively from described base portion, be extended with a weld part from the bending downwards of described base portion, described weld part part is extended described accepting groove downwards, and is provided with a hook part in its end; The described material portion that connects is fixed with the 2 first madial walls interference that described accepting groove is oppositely arranged respectively, moves down in order to limit described terminal, and described hook part enters and be positioned at the bottom of described accepting groove below, moves up in order to limit described terminal.

Compared with prior art, described base portion owing to described terminal in the utility model electric connector extends upward the described first madial wall interference engagement location that is provided with described two material portions of company and described accepting groove, making it limit described terminal moves down, described hook part on the described weld part is limited described terminal and is moved up, so, make that the location of described terminal is good.

In addition, described base portion upwards and from described adjutage both sides is extended with the described material portion that connects respectively, and described like this terminal is located better in processing procedure, during as operations such as punching press, bendings as described in terminal be not easy torsional deformation, thereby make that described terminal processing procedure is more stable.
