Abstract
The utility model discloses a contact couple for a dynamic electric connector. The outer surface of the inserting and combining part of an inserting needle is a conical surface, the front end of a jack is axially slotted and is radially provided with a spring buckle, and the inner aperture of the front end of the jack is reefed. The contact couple has small extracting force and small contact resistance, filth on a plug can be automatically removed, and contact performance is free from the influence of the stress of an outer conducting wire.
Description
The utility model relates to the electric connector that socket has spring member on every side.
Dynamic connector of the prior art, reliable for guaranteeing contact, the contact coupling be contact pin with jack on or utilize flexible member that contact pin is closely contacted with jack around it.Chinese patent specification 92229049,0 discloses a kind of cone plug type electric connector, and the contact-making surface of plug and jack is conical, and plug locks by outside locking device after filling in jack again, makes to connect and finishes; Axle spring is arranged with the axial sinciput of jack between jack and the electrical connector housing simultaneously, to guarantee the normal pressure contact between plug-socket.The contact coupling withdrawal force of this cone plug type electric connector is big, and its model KC20 electric connector contact coupling withdrawal force is 300～800N, and damaged reduces next contact area so might make the contact surface that plastic deformation takes place, and increases contact resistance; Withdrawal force is bigger than normal simultaneously, causes operation painstaking; And taper surface contact do not possess the ability of rejecting dirt, dirts such as dust, silt, coal ash, fiber, wood chip, cotton, hair can be squeezed securely on the contrary to be clipped on the contact-making surface, causes loose contact, thereby is not suitable for the operational environment in field; In addition, when the jack afterbody connects thicker lead, connect two 70mm as KC20 electric connector jack afterbody
2Lead or a 150mm
2Lead the time, the pulling force on the lead can be delivered on the jack, makes jack axial play in electric connector, may cause loose contact, when serious plug is separated with jack and does not contact.
The purpose of this utility model provides the less electric connector contact coupling of a kind of withdrawal force, and its contact site has the ability of automatic rejecting dirt.
For solving above task, be that the jack matrix mating side of the face of cylinder or taper seat is a front end edge axis direction fluting at inner surface, make the jack front end form a plurality of contact lobes, in the periphery of jack front end spring band is set radially simultaneously.Contact pin is conical.When contact pin when the endoporus of jack advances, the jack front end respectively to contact lobe promptly outwardly-bent, spring band is also driven and radial dilatation, the strain of contact lobe and spring band produces the resilient clamp effect to contact pin, make to keep normal pressure between contact lobe and contact pin and obtain enough contacts area, realize contact reliably.The jack front end closes up, and further closes up under the effect of spring band, so this oral area has the examination of wiping ability, when dirt particulate attached to the contact pin contact-making surface on, along with the insertion of contact pin, dirt is disallowable at the jack oral area.Produce metal oxide film when the contact pin contact-making surface, also can allow fresh metal come in contact, reduced contact resistance by jack oral area galling oxide-film.
Because what adopt is the radial spring hoop, can make axial restraint between jack and the insulating mounting plate, so jack can not be subjected to cause the contact-making surface loose contact from the influence of the power of lead.
Effect of the present utility model is: withdrawal force is little, is equal to or greater than the power electric connector of 400A for operating current, and withdrawal force is greatly in 80～300N scope; Contact resistance is little, approximately is 1/2nd of cone plug type electric connector; Have the ability of dirt on the automatic rejecting contact-making surface, be suitable for field work; The suffered external force of outer conductor can not cause loose contact.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the pin junction composition.
Fig. 2 is jack structure figure.
Fig. 3 is the vertical view of Fig. 2.
The part outer surface 1 that plugs together of contact pin is taper seat among Fig. 1.Jack front end among Fig. 2 is because axially grooved and form a plurality of contact lobes 2, for example six contact lobes representing of Fig. 3.The periphery of also expressing the contact lobe among Fig. 2 radially is provided with spring band 3.The closing in of jack front end is not obviously drawn in Fig. 2, but exists in the reality.Jack and insulating mounting plate 4 fix, so jack can not be with respect to insulating mounting plate 4 and axial motion, the suffered power of lead that the jack rear end connects can not influence the contact condition of jack front end.
Claims (3)
1, a kind of electric connector contact coupling is made up of contact pin and jack, it is characterized in that: a plurality of contact lobes of the axially grooved formation of jack front end (2), in the periphery of contact lobe spring band (3) is arranged radially, and the part outer surface (1) that plugs together of contact pin is a taper seat simultaneously.
2, electric connector contact coupling according to claim 1, it is characterized in that: the axially grooved inner surface of jack front end is the face of cylinder or taper seat.
3, according to claim 1 described electric connector contact coupling, it is characterized in that: the jack front end closes up.
