But in above-mentioned documents, a pair of terminal is only provided on terminal base, after sheet metal is inserted into terminal, terminal
It can deform upon, so that sheet metal can not be completely attached to terminal, constrain the current-carrying capability of terminal, this problem needs
It solves.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of electric contact piece component, tool
There is the advantage that current-carrying capability is strong.
To achieve the above object, the utility model provides following technical solution：
A kind of electric contact piece component, including terminal base, on the terminal base fixed setting be useful for clamping metal insert
Contact chip, the contact chip are set as multipair.
By using above-mentioned technical proposal, contact chip is set as multipair, the metal insert of male end is inserted into the electricity of female end
After contact chip component, multipair contact chip with metal insert Elastic Contact, at double the metal insert for increasing male end with
Contact point quantity between the electric contact piece component of female end so that the current-carrying capability of electric contact piece component greatly reinforces.
Further, the contact chip is arranged along the plugging direction of metal insert.
By using above-mentioned technical proposal so that metal insert is facilitated insertion between each pair of contact chip, so that more
Contact chip is come into full contact with metal insert, contact point quantity is increased so that the current-carrying capability of electric contact piece component is effective
Reinforce.
Further, the contact chip is set as contact chip in a pair of of out-connecting contact and a pair, and the interior contact chip is located at
Between out-connecting contact.
By using above-mentioned technical proposal, between interior contact chip is set to out-connecting contact, electric contact piece group is being increased
While part current-carrying capability, there is no additional space volume is occupied, it is conducive to the installation and use of electric contact piece component.
Further, the out-connecting contact includes the outer fixinig plate being bonded with the side wall of terminal base, one with outer fixinig plate
Hold the outer connection sheet being fixedly connected and the outer intermediate plate being fixedly connected with the one end of outer connection sheet far from outer fixinig plate, the outer intermediate plate
One end far from outer connection sheet is provided with several outer clip tooths；Two pieces of outer fixinig plates are fixedly installed on terminal base two respectively
Side.
By using above-mentioned technical proposal, two pieces of outer fixinig plates are fixedly installed on terminal base both sides respectively, by the gold of male end
After belonging between inserted sheet two pieces of outer intermediate plates of insertion, outer clip tooth can keep the state contacted with metal insert under the action of elastic force,
To ensure that the stability of high current transmission.
Further, the interior contact chip include the interior fixinig plate being bonded with the side wall of terminal base, it is close with interior fixinig plate
The interior connection sheet and the inner clamp piece being fixedly connected close to one end of outer clip tooth with interior connection sheet that one end of outer clip tooth is fixedly connected, institute
