Abstract
The utility model relates to a kind of big current contact, comprise the contact pin and jack that match, described jack comprises receptacle body, and described receptacle body is provided with a plurality of interior hat spring, the inside of described receptacle body is provided with an interior contact pin, and described interior contact pin is provided with a plurality of outer hat spring; Described contact pin comprise pin body and corresponding with jack in the pin holes that contacts of contact pin; Have in jack one to three with contact pin exterior surface in be preced with spring or other reed, with the reed of one to three the outer hat spring contacted with contact pin endoporus or other form on interior contact pin.When contact pin and jack come in contact, the interior hat spring be with in jack and contact pin surface contact, outer hat spring on interior contact pin simultaneously in jack contacts with hole corresponding in contact pin, realize hyperboloid contact, contact-making surface is more, guidance quality is better, and contact resistance is lower, is specially adapted to the high-power transmission means of big current.
Description
Technical field
The utility model relates to the contact on a kind of connector, especially a kind of big current contact.
Background technology
When the transmission big current of connector, the current value of caloric value T=I2(transmission) * R(contact resistance, crimping resistance etc.) the * t(time); Because the current value I of transmission and the time t of transmission is fixed, the caloric value to reduce connector only has R reduction, and the main part of resistance R that connector inside produces all comes from contact resistance; Can start with from reduction contact resistance so reduce its caloric value.
And a lot of high current connector is the environment having vibrations for new-energy automobile, railway locomotive etc., traditional contact is general all only by single curved face contact, easily there is loose contact at vibration environment like this, even occur the situations such as arcing, scaling loss connector and equipment.
Summary of the invention
The utility model object provides a kind of big current contact to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of big current contact, comprise the contact pin and jack that match, described jack comprises receptacle body, described receptacle body is provided with a plurality of interior hat spring, the inside of described receptacle body is provided with an interior contact pin, and described interior contact pin is provided with a plurality of outer hat spring; Described contact pin comprise pin body and corresponding with jack in the pin holes that contacts of contact pin.
Further, described interior contact pin siphunculus elastic conjunction is in jack, and the interior contact pin contact-making surface that described interior contact pin contacts with jack is elastic conjunction face.
Further, described jack inside has in one to three and is preced with spring.
Further, the interior contact pin of described jack inside is preced with spring outward with one to three.
Further, the contact-making surface of described outer hat spring and pin holes is inside contact surface.
Further, the position that described interior hat spring contacts with the outside of pin body is external contact face.
Because technique scheme is used, the utility model compared with prior art has following advantage:
The contact contact-making surface of the technology that big current contact contact-making surface of the present utility model is more traditional is more, and interior hat spring contacts with outer hat spring simultaneously, can ensure lower contact resistance, realizes reducing the caloric value in transmission; Big current contact guidance quality of the present utility model is better, and contact pin is inserted in jack, and the interpolation pin simultaneously in jack is inserted in contact pin, and anti-shake performance is better.

Accompanying drawing 1 is the structural representation of the jack of existing contact;
Accompanying drawing 2 is the structural representation of the contact pin of existing contact;
Accompanying drawing 3 is the structural representation of the jack of the utility model big current contact;
Accompanying drawing 4 is the structural representation of the contact pin of the utility model big current contact;
Structural representation when accompanying drawing 5 is the contact of the utility model big current contact.
Wherein, the jack of A, existing contact; The contact pin of B, existing contact; 11, jack; 1, receptacle body; 2, interior hat spring; 3, interior contact pin; 4, outer hat spring; 5, interior contact pin contact-making surface; 22, contact pin; 6, pin body; 7, pin holes; 8, inside contact surface; 9, external contact face.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Big current contact as shown in Figure 3 and Figure 4, mainly comprises contact pin 22 and jack 11.Contact pin 22 and jack 11 cooperatively interact, and contact pin 22 can insert (being namely fitted together to) in jack 11, make contact pin 22 and jack 11 be interconnected in aggregates.
Wherein, contact pin 22 mainly comprises pin body 6(contact pin body), and the pin holes 7 contacted with interior contact pin 3, defining one end chimeric with jack 11 is that a holds, with jack 11 away from one end be that b holds.
Jack 11 mainly comprises receptacle body 1, interior hat spring 2, interior contact pin 3, outer hat spring 4, and interior contact pin 3 adopts elastic conjunction with receptacle body 1 or welds; First outer hat spring 4 is contained on interior contact pin 3, becomes assembly c; Interior hat spring 2 is encased in receptacle body 1, becomes assembly d, then assembling on assembly c force fit to assembly d is namely completed.
As shown in Figure 5, when contact pin and jack insert and after, the quantity according to interior hat spring 2 and outer hat spring 4 can produce multiple contact-making surface, concrete quantity be interior hat spring 2 and outer hat spring 4 quantity and, interior hat spring 2 produces the external contact face 9 shown in Fig. 5 with pin body 6; Outer hat spring 4 produces the inside contact surface 8 shown in Fig. 5 with pin holes 7.More than traditional big current contact contact-making surface, spigot surface is more, and contact resistance is lower, shock resistance is stronger.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
