Abstract

Protrusions 17 facing inside from the left and right side walls 12 are made in two locations at a predetermined distance from each other along the length of the resilient contacting strip 15 under it. The parts of the resilient contacting strip 15 corresponding to the said left and right protrusions 17 are made wider than the other parts of the strip. As the result of this, when the resilient contacting strip 15 is bent downward, it comes in contact with the entire length of the protrusions 17 from their bases.

But, in above-mentioned existing structure, because projection only is located at a position of regulation with respect to vertical total length of elastic contact chip, therefore concentrate when power and act on when being provided with protruding position, this part that also can prevent elastic contact chip surpasses Hookean region and is out of shape, and concentrate when acting on the position of not establishing projection when power, this part that can not prevent elastic contact chip surpasses Hookean region and the possibility of being out of shape is very big.

In addition, under the situation of existing structure, during with the downward compression elasticity contact chip of brute force, should be able to stop elastic contact chip to make to surpass the projection that moves of predetermined distance downwards originally, and can not support this brute force fully sometimes and be bent.

The present invention In view of the foregoing proposes, its objective is provides a kind of like this receptacle terminal, promptly no matter masterpiece is used in the local time of elastic contact chip, or forceful action is when they are whole, and this receptacle terminal can both prevent that elastic contact chip from surpassing Hookean region and be out of shape.

In order to achieve the above object, receptacle terminal of the present invention has the substrate that extends along fore-and-aft direction; The left and right sides sidewall of upwards erectting from the left and right sides of this substrate; From the front end of aforesaid substrate elastic contact chip to inner rear bending extension; And be arranged in above-mentioned elastic contact chip the below, with this elastic contact chip at a distance of the distance of regulation, from least one sidewall of above-mentioned left and right sides sidewall to projecting inward projection.The feature of this receptacle terminal is: along aforementioned elastic contact chip vertically be provided with several above-mentioned projectioies, the width of the part corresponding with this projection is wideer than other parts on the aforementioned elastic contact chip.

If adopt receptacle terminal of the present invention, owing to vertically be provided with several projectioies along elastic contact chip, when power is done the time spent downwards, the elastic contact chip that can move down in vertical several positions supports of elastic contact chip, therefore both having exerted all one's strength to concentrate acts on the elastic contact chip position longitudinally, and this part that also can prevent elastic contact chip surpasses Hookean region and is out of shape.

In addition, since wideer than other parts on the elastic contact chip with protruding corresponding part, compare with existing structure, elastic contact chip is touched near the root of projection, therefore be subjected to the onesize masterpiece time spent, projection also can be crooked.Therefore, when both having made forceful action on elastic contact chip, projection also can hold on downward the moving of elastic contact chip fully, thereby can prevent that elastic contact chip from surpassing Hookean region and be out of shape.
