Background technology:

Connector is the Connection Element that is used on power supply and the electronic signal, and it produces by mechanical means and electrically connects.Connector extensively applies to fields such as various electronic equipments, communication apparatus, instrument and meter, intelligent program-controlled equipment, lighting apparatus, warning device, household electrical appliance and various power supply products, comprise display, computer main board, stored-program control exchange, digital camera, MP4, various mobile storage disc, cordless telephone, intercom, mobile phone, digital household appliances and electronic toy etc., electrically connect reliably for various products provide accurate.

Connector is divided into by purposes: one, and concentric connector, connector is a kind of small-sized connector assembly formula connector with one heart, its volume is little and have the function of switch concurrently, is applicable to low-frequency channel, is used in the wiring of earphone, microphone and external power supply more; Two, the strip columnwise connector, the number of the lead-in wire of strip columnwise connector is generally below the dozens of, is applicable to that printed circuit board is connected with the circuit of device in the equipment; Three, tape cable connector, the socket of tape cable connector directly are welded on the printed circuit board, and plug and flat cable adopt the puncture crimping, can once finish, and contact is reliable, and is easy to use, is applicable to the connection of instrument and meter circuit; Four, cylindrical connector, cylindrical connector have little, the high reliability features of volume, can satisfy the needs that cable connects between the electronic equipment; Five, rectangular connector, rectangular connector generally are provided with locking device, are mainly used in being electrically connected of electronic equipment, intelligent instrumentation and control electronics; Six, the water pressure resistance hermetically sealed connector, this connector mostly is cylindrical connector, the circuit connection that is applicable in the water or works under the severe environmental conditions; Seven, radio frequency (RF) coaxial connector, radio frequency (RF) coaxial connector have characteristics such as volume is little, in light weight, easy to use, are useful in to connect radio frequency cable in the high-frequency circuit of wireless device and electronic instrument and use.

Existing a kind of double female connectors that is used for printed circuit board (pcb board), it comprises plastic body and plurality of rows pin, the plurality of rows pin is arranged in double being installed on the plastic body, described row's pin comprises contact jaw and the welding ends that connects as one, contact jaw is inserted in the plastic body, and welding ends passes plastic body.This double female connectors, its contact jaw bottom and top are opening, when this double female connectors of welding, tin liquor is scurried open top to contact jaw along welding ends through the bottom opening of contact jaw easily, final open top of stopping up contact jaw, cause the public connector terminal can't insert the situation of contact jaw, reduced product quality and stability.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, a kind of double female connectors with anti-wicking structure is provided, the contact jaw of this double female connectors can intercept tin liquor, prevents the open top of tin liquor obstruction contact jaw, improves product quality and stability.

For achieving the above object, the utility model is achieved through the following technical solutions: the double female connectors of the anti-wicking structure of band, it comprises plastic body and plurality of rows pin, the plurality of rows pin is arranged in double being installed on the plastic body, described row's pin comprises contact jaw and the welding ends that connects as one, contact jaw is inserted in the plastic body, and welding ends passes plastic body, and described contact jaw is provided with the retaining pin that retaining is established the contact jaw bottom opening.

Described retaining pin and contact jaw are one-body molded.

Row's centreline spacing PH of described double row's pin is 2.00 ± 0.05mm, and row's pin centreline spacing ZH of the adjacent row's pin of every row is 2.00 ± 0.10mm.

The height H of described plastic body is 4.30 ± 0.15mm.

The width W of described plastic body is 4.50 ± 0.15mm.

The utility model beneficial effect is: the double female connectors of the anti-wicking structure of band described in the utility model, its contact jaw is provided with the retaining pin that retaining is established the contact jaw bottom opening, adopt the double female connectors of this structure, when welding, the retaining pin can intercept tin liquor and scurry open top to contact jaw along welding ends, effectively prevent the open top of tin liquor obstruction contact jaw, improve product quality and stability.
