Abstract
The invention relates to the field of an electric connector, in particular to a high-current jack contact. The high-current jack contact comprises a jack rear sleeve and a core sleeve assembled in the jack rear sleeve, wherein the core sleeve is a crown belt or a torsional spring; a cylindrical structure which is connected end to end is formed by the core sleeve in the jack rear sleeve along the circumferential direction of the jack rear sleeve; the core sleeve is in interference fit with the jack rear sleeve. Due to the fact that when the high-current jack contact is matched with an adaptive contact pin, the high-current jack contact does not leave a space for the deflection of the contact pin, so the reliability of matching with the contact pin can be greatly improved; furthermore, due to the fact that the core sleeve is in interference fit with the jack rear sleeve, the pressure between the core sleeve and the jack rear sleeve can be greatly increased, and the whole resistance of the contact is reduced. In conclusion, according to the high-current jack contact provided by the invention, the problem that the existing contact used for transmitting high current is not reliably in contact with the adaptive contact pin and is high in resistance is solved.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of big current jack contact.
Background technology
Along with constantly the widening of application of electric connector, the large-power occasions transmitting big current is needed also to start to use electric connector to realize continuing and cut-offfing of electric loop at some.Just the generation of heavy-current electric connector has been impelled thus.As the critical piece of through-put power, contact there is no doubt that the main parts of heavy-current electric connector, can say that the transmittability of contact directly determines the through-put power of electric connector.
Jack contact conventional in current heavy-current electric connector has string of a hat jack and torsion spring jack.String of a hat jack and torsion spring jack are all made up of two parts, it is overlap after core retainer plate and jack respectively, wherein core retainer plate is divided into the string of a hat and torsion spring, overlap after the string of a hat and jack and form string of a hat jack, overlap after torsion spring and jack and form torsion spring jack, the string of a hat and torsion spring be for contact pin Elastic Contact with through-put power, after jack overlap the contact pin be used to as the string of a hat and torsion spring and adaptation rigid support is provided.
Existing above-mentioned jack, when assembling, need making its external diameter diminish to the cylindrical applying external force of the string of a hat or torsion spring, so that the aperture by overlapping front end after jack, being seated the elasticity of rear dependence part self, on the inwall overlapped after being attached to jack.There are three weak points in said structure, first, after the string of a hat or torsion spring flick in overlapping after jack, there will be a larger breach, namely the end face being assembled to the string of a hat after jack in cover or torsion spring is c-shaped, and 360 ° of cannot realize between adaptive contact pin contact, contact pin unbalance stress, easy deflection breach side, contact reliability is unstable; The second, be Elastic Contact between overlapping after the string of a hat or torsion spring and jack, the contact between part is limited, makes the contact resistance of contact entirety larger; 3rd, when product is in vibration or shock environment, contact pin, under impact force action, drives the string of a hat or torsion spring in axial direction play or rotation, while accelerating parts depreciation, reduces the stability of current delivery.
Summary of the invention
The object of the present invention is to provide a kind of big current jack contact, with solve existing for transmit big current contact exist contact unreliable and that resistance is large problem with adaptive contact pin.
In order to solve the problem, big current jack contact of the present invention is by the following technical solutions: big current jack contact, cover and the core retainer plate after being assemblied in jack in cover after comprising jack, core retainer plate is the string of a hat or torsion spring, the circumference of overlapping after jack during described core retainer plate overlaps after jack form end to end core structure and with jack after overlap interference fit.
The front end overlapped after described jack is fixedly equipped with protheca, and the front end of core retainer plate to be pressed abd fixed on after jack between cover with protheca.
Described protheca be inserted into rear cover front end and with rear cover interference fit.
The front end of described core retainer plate is laid with bullet pawl that extend forward, that form cantilever design, and core retainer plate is pressed abd fixed in rear cover by coordinating with described bullet pawl by protheca.
Due to the core retainer plate of big current jack contact of the present invention overlap after jack in the circumference of overlapping after jack form end to end core structure and with jack after overlap interference fit.Therefore, when coordinating with adaptive contact pin, move to the deflection of contact pin to make allowances, thus can greatly improve the reliability coordinated with contact pin, in addition, interference fit between overlapping after core retainer plate and jack, thus the pressure between overlapping after greatly can increasing core retainer plate and jack, reduce the resistance of contact entirety.In sum, big current jack contact of the present invention solve existing for transmit big current contact exist contact unreliable and that resistance is large problem with adaptive contact pin.

Embodiment
The embodiment of big current jack contact, as Figure 1-4, the core retainer plate 12 overlapping 11 after this big current jack contact comprises jack and overlap after being assemblied in jack in 11.
Overlap 11 after jack except front port structure, other structure is prior art, therefore, only describes in detail to the front port position overlapping 11 after jack herein.Unlike the prior art mainly, the front port place overlapping 11 after the jack in the present embodiment is provided with expanding structure, and the endoporus front portion overlapping 11 after this expanding structure makes jack constitutes pre-large post-small stepped hole.
Core retainer plate 12 is the critical pieces for coordinating with adaptive contact pin, in the present embodiment, what core retainer plate 12 specifically adopted is torsion spring, it is curling that it overlaps the circumference of overlapping after jack in 11 after jack, form end to end core structure, the external diameter of this core structure is greater than the bore inner diameter of cover 11 after jack, thus is formed and overlap the interference fit state between 11 after jack, increase contact therebetween.In addition, in the present embodiment, overlap in the front port of 11 and be equipped with protheca 13 after jack, the front end of core retainer plate 12 to be pressed abd fixed on after jack between cover 11 and protheca 13.Specifically, the front end of core retainer plate 12 is provided with bullet pawl 14 that extend forward, that form cantilever design, what protheca 13 adopted is the structure of multidiameter shell type, overlap interference fit after the large diameter portion of its front portion and jack, core retainer plate is pressed abd fixed in rear cover by coordinating with described bullet pawl by the path part at rear portion.Arranging of protheca can further fix core retainer plate 12, and the problem avoiding core retainer plate 12 to loosen under the factors such as vibration occurs.
In other embodiment of big current jack contact, core retainer plate can also be specifically the string of a hat.
