Existing a kind of row's female connectors that is used for printed circuit board (pcb board), it comprises plastic body, and the plurality of terminals that is installed in described plastic body; Described terminal comprises contact jaw and welding ends, and contact jaw is inserted in the plastic body, and welding ends is piercing in the plastic body lower surface, and welding ends is welded on the pcb board, contact jaw be used for male terminal to inserting; Adopt row's female connectors of this structure, because the contact jaw of terminal is made up of U type mouth and contact flat spring, U type mouth and welding ends are one-body molded, the rim of a cup that contact flat spring forms outwardly, there are 2 deficiencies in this terminal: 1, when terminal in punching out, electroplate, when cutting or assembling, because of causing the distortion of terminal rim of a cup, external force damages easily, just make contact flat spring produce inelastic deformation and damage, owing to exist this point not enough, in the process of manufacture of row's female connectors, usually to shut down maintenance, both reduce production efficiency, improved production cost and product fraction defective again; 2, after terminal and plastic body are formed finished product, when with the male terminal of male seat when inserting, if the male terminal oblique cutting of male seat is gone into to arrange in the terminal of female connectors, easily on business terminal withstands the terminal rim of a cup of row's female connectors and the damage of the terminal of the row's of causing female connectors, because exist this point not enough, the finished product of the row's of making female connectors uses fraction defective higher.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, a kind of row's female connectors of anti-rim of a cup terminal is provided, the terminal rim of a cup of this row's female connectors is not fragile, can effectively enhance productivity, and reduces production costs, product fraction defective and finished product use fraction defective.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of row's female connectors of anti-rim of a cup terminal, and it comprises plastic body, and the plurality of terminals that is installed in described plastic body; Described terminal comprises contact jaw and welding ends, and contact jaw is inserted in the plastic body, and welding ends is piercing in the plastic body lower surface, and described contact jaw is followed successively by integrated U type mouth, contact flat spring and the following U type mouth gone up from top to bottom, and following U type mouth and welding ends are one-body molded.

Described plurality of terminals is arranged in single-line held and is located at described plastic body.

Described plurality of terminals is arranged in the double described plastic body that is installed in.

The row's centreline spacing PH that is arranged in double terminal is 2.54 ± 0.1mm, and the terminal centreline spacing ZH of every row's terminals of adjacent is 2.54 ± 0.05mm.

The height H of described plastic body is 4.50 ± 0.15mm.

The width W of described plastic body is 5.08 ± 0.15mm.

Described welding ends is the bending structure.

The utility model beneficial effect is: row's female connectors of a kind of anti-rim of a cup terminal described in the utility model, the contact jaw of its terminal are followed successively by integrated U type mouth, contact flat spring and the following U type mouth gone up from top to bottom, and following U type mouth and welding ends are one-body molded; Adopt the terminal of this structure, the rim of a cup that is formed by contact flat spring places between U type mouth and the following U type mouth, last U type mouth and following U type mouth can play the effect of effective protection rim of a cup, avoid the rim of a cup of terminal to damage because of external force in the course of processing, assembling process and use; Therefore, row's female connectors of anti-rim of a cup terminal described in the utility model, its terminal rim of a cup is not fragile, can effectively enhance productivity, and reduces production costs, product fraction defective and finished product use fraction defective.
