Technical field:

The utility model relates to the connector technique field, relates in particular to the double female connectors of four sides spring-piece type.

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, and the plurality of rows pin is arranged in double being installed on the plastic body, and 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 structure are U type three surface contact structures or Y type two surface contact structures, no matter be that public connector terminal straight cutting is gone into contact jaw, still oblique cutting is gone into contact jaw, the public connector terminal all skids off contact jaw easily, causes the male and female loose contact, and the phenomenon that opens circuit.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of four sides spring-piece type double female connectors, and the contact jaw of this double female connectors and public connector termination contact are good, can avoid the phenomenon that opens circuit.

For achieving the above object, the utility model is achieved through the following technical solutions: the double female connectors of four sides spring-piece type, 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 four sides of described contact jaw are respectively equipped with shell fragment.

Described welding ends is the bending end.

Row's centreline spacing PH of double row's pin is 2.00 ± 0.10mm, 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 3.56 ± 0.15mm.

The width W of described plastic body is 4.00 ± 0.15mm.

The utility model beneficial effect is: the double female connectors of four sides described in the utility model spring-piece type, four sides of its contact jaw are respectively equipped with shell fragment, adopt the double female connectors of this structure, it between its contact jaw and the public connector terminal four sides spring-piece type way of contact, no matter be that public connector terminal straight cutting is gone into contact jaw, still oblique cutting is gone into contact jaw, the public connector terminal can contact with the minimum two sides shell fragment of contact jaw, therefore, the utlity model has contact jaw and the public connector termination contact is good, can avoid taking place the advantage of breaking phenomena.
