Description

The double female connectors of band metal earclip

Technical field:

The utility model relates to the connector technique field, relates in particular to the double female connectors of band metal earclip.

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 applied to the mainboard interface of computer and perimeter equipment, it comprises plastic body and plurality of rows pin, the plurality of rows pin is arranged in double being installed on the plastic body, the plastic body two sides of this double female connectors are provided with the plastic cement earclip, and double female connectors passes through plastic cement earclip spiral-lock at the mainboard interface two ends.Because plastic cement earclip shared space in both sides is bigger, often make this double female connectors because of the restriction of part mainboard locus can't spiral-lock to mainboard; And the insufficient strength of plastic cement earclip, rupture easily when frequently loading and unloading.

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 the metal earclip is provided, and occupation space is less during this double female connectors spiral-lock, is not subjected to the restriction of mainboard locus, and the intensity of metal earclip is higher, easy fracture not when frequently loading and unloading.

For achieving the above object, the utility model is achieved through the following technical solutions: the double female connectors of band metal earclip, it comprises plastic body and plurality of rows pin, the plurality of rows pin is arranged in double being installed on the plastic body, also comprise two metal metal earclips, two metal ears be located in the two ends of plastic body same side.

Described metal earclip and plastic body are hinged.

Row's centreline spacing PH of described double row's pin is 2.54 ± 0.10mm, and row's pin centreline spacing ZH of the adjacent row's pin of every row is 2.54 ± 0.10mm.

The height H of described plastic body is 9.80 ± 0.25mm.

The width W of described plastic body is 9.20 ± 0.25mm.

The utility model beneficial effect is: the double female connectors of band metal earclip described in the utility model, owing to earclip is located at the two ends of plastic body same side, the earclip occupation space of the same side is littler than the earclip occupation space of both sides, therefore, occupation space is less during the utility model spiral-lock, be not subjected to the restriction of mainboard locus, and the intensity of metal earclip is higher, easy fracture not when frequently loading and unloading.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the A-A cutaway view of Fig. 1.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1 to Figure 3, the double female connectors of band metal earclip, it comprises plastic body 1 and plurality of rows pin 2, plurality of rows pin 2 is arranged in double being installed on the plastic body 1, comprise that also 3, two metal earclips 3 of two metal metal earclips are located at the two ends of plastic body 1 same side.In the present embodiment, described metal earclip 3 is hinged with plastic body 1.

Row's centreline spacing PH of described double row's pin 2 is 2.54 ± 0.10mm, and row's pin centreline spacing ZH of the adjacent row's pin 2 of every row is 2.54 ± 0.10mm.The height H of described plastic body 1 is 9.80 ± 0.25mm, and the width W of plastic body 1 is 9.20 ± 0.25mm, and the length of plastic body 1 is relevant with the quantity that every row arranges pin 2.Therefore, the utility model also has the little advantage of volume.

The double female connectors of band metal earclip 3 described in the utility model, two ends in plastic body 1 same side are hinged with metal earclip 3 respectively, should double female connectors spiral-lock when the mainboard interface two ends, two metal earclip 3 occupation space of the same side are smaller.Occupation space is less when the utlity model has spiral-lock, be not subjected to the restriction of mainboard locus, and the intensity of metal earclip 3 is higher, and the advantage of easy fracture not when frequently loading and unloading adopts the double female connectors of this structure to make that also the assembly of male and female connector is more convenient.In the present embodiment, the operating temperature range of the double female connectors of this band metal earclip is-40 ℃～+ 105 ℃, and insulation impedance is 1000M Ω Min, and contact impedance is 20M Ω Max, and proof voltage is 1000V AC/Minute, and rated current is 3.0AMP.

The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
