Abstract
The invention discloses a jack of a high-elasticity pawl spring type, comprising a jacket (1), a pawl spring (2) and a jack. The pawl spring (2) is assembled and arranged on the excircle of the jack (3) which is provided with steps for realizing the axial limitation of the pawl spring (2), the pawl spring (2) is a rotary spare part provided with a plurality of elastic contact sheets, the end parts of the plurality of elastic contact sheets are folded into an incircle to form an elastic structure which can be strutted and have closing force, the jacket (1) is sleeved on the peripheries of the pawl spring (2) and the jack (3) so as to fix the pawl spring (2) in the jack (3), a guiding part in arc bending is arranged at the end part of each elastic contact sheet, and the jacket (1) and the jack (3) are in interference fit and compression joint to reliably fix the pawl spring (2) in the jack (3). The invention has a simple structure, high contact reliability, long contact length, small plugging force, overstress deformation resistance and favorable guidance.
Description
Technical field
The present invention relates to technical field of electric connectors, relate in particular to a kind of high resiliency spring pawl formula jack.
Background technology
The contact numerous types of connector, commonly used have cylindrical shape contact, stranded elastic contact pin contact, wire spring socket contact, hat spring socket contact and a square contact.In these contacts, wire spring socket contact and stranded elastic contact pin contact have higher reliability and low contact engaging and separating force.The structural shape of hat spring socket contact is then identical with the wire spring socket contact with mechanical model, and when keeping advantage, avoided wire spring socket contact piece structure complexity, fracture of wire, anti-probe damage ability is low, ampacity is little and tenaculum hot-line insertion and extraction problems such as (plug and play) not, but the hat spring socket all contacts with contact pin in one section zone, centre of jack with wire spring socket, and the contact length of its contact pin and jack is than the weak point that contacts in the jack aperture.Because contact length is shorter, when plugging together not in place or inclination is arranged, may have the loose contact phenomenon, and the part use occasion is restricted.
Summary of the invention
The objective of the invention is: a kind of high resiliency spring pawl formula jack is provided, and it is simple in structure, have high contact reliability, contact length is long, contact engaging and separating force is low, can prevent the overstress distortion, and have good guidance.
Technical scheme of the present invention is: a kind of high resiliency spring pawl formula jack, it comprises sheath, spring pawl, jack, described spring pawl assembling is arranged on the jack cylindrical, jack is provided with the step of realizing spring pawl axial limiting, described spring pawl is the rotary part with a plurality of elastic contact chips, and the end of a plurality of elastic contact chips closes up into an inscribed circle, and formation can strut and have the elastic construction of closing force, described sheath is set in spring pawl and jack periphery, so that the spring pawl is fixed on the jack.
Below be further explanation to technique scheme:
The end of described elastic contact chip is provided with the guide part of circular arc bending.
Described sheath and jack interference fit.
Described sheath is provided with the pressure contact portion with the jack crimping.
Described spring pawl is made through blanking, bending, volume circle by beryllium bronze band.
Advantage of the present invention is: high resiliency spring pawl formula jack of the present invention, adopt elastomeric spring pawl, form by step location and interference fit, be fixed on the spring pawl in the jack reliably, form good being electrically connected, and anti-overstress distortion of configuration sheath and good guidance, fair surplus contact system in parallel formed, obtain highly reliable being electrically connected, have characteristics simple in structure, that contact length is long and contact engaging and separating force is low.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the main cutaway view of the preferred embodiment of the present invention;
Fig. 2 is the main cutaway view of the spring pawl of the preferred embodiment of the present invention;
Fig. 3 is the vertical view of the spring pawl of the preferred embodiment of the present invention.
Wherein: 1 sheath; 2 spring pawls; 3 jacks; 5 pressure contact portions.
Embodiment
Embodiment: as shown in Figure 1, a kind of high resiliency spring pawl formula jack is made up of sheath 1, spring pawl 2 and jack 3.Spring pawl 2 is core parts of spring pawl formula jack, it by beryllium bronze band behind blanking, bending, volume circle, formation has the rotary part (with reference to figure 2, Fig. 3) of a plurality of elastic contact chips, the end of a plurality of elastic contact chips closes up, form an inscribed circle, when contact pin and spring pawl formula jack plugged together, contact pin suitably strutted the elastic contact chip at inscribed circle place, formation elasticity connects, and finishes electrical communication.In order to lead, the end bent of each elastic contact chip certain circular arc.Spring pawl 2 is assembled on jack 3 cylindricals, and realizes axial limiting by the step that jack 3 is provided with, and for spring pawl 2 is fixed on the jack 3 reliably, has disposed sheath 1, sheath 1 by with jack 3 interference fit and crimping, spring pawl 2 is fixed on the jack 3 reliably.In addition, configuration makes spring pawl formula jack have good guiding behind the sheath 1, and the strain of spring pawl 2 is carried out spacing, plays the effect of anti-overstress distortion.When contact pin and spring pawl formula jack plugged together, contact pin formed Elastic Contact in the end of spring pawl 2, owing to be the envelope contact of a plurality of elastic contact chips, formed fair surplus contact system in parallel, made spring pawl formula jack have high contact reliability.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present invention, rather than restriction.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
