The elastic contact element has the advantages that: the elastic contact element can be arranged on the contact pin of the electrical connector, and the contact resistance is small, and the contact is reliable; the elastic contact element is not easy to deform and can transmit heavy current.

Description

A kind of resilient contact that is installed on the electric connector contact pin
Technical field
The utility model relates to a kind of electric contacting piece, especially a kind of resilient contact that is installed on the electric connector contact pin belongs to technical field of electric connectors.
Background technology
At present, the common contact that is installed on the electric connector contact pin has outer hat spring contact, claims the lantern spring again.Its similar lantern shape that is small at both ends and big in the middle when contact pin and jack plug together, is preced with elastic contact chip on the spring contact outward and is just formed and be electrically connected.In actual production process, outer hat spring contact is owing to processed or the restriction of assembly precision, the layout of each elastic contact chip is not to be one to justify accurately on the outer hat spring contact, therefore following phenomenon can occur: certain sheet or several contact chips can not keep well contacting with jack; What each elastic contact chip was subjected to is whole positive pressure that jack applies in the contact position, and inhomogeneous, cause plug and socket under the situation of often plug, certain sheet or several elastic contact chips produce fatigue deformation, influence contact performance, even produce the loose contact phenomenon.Strain can take place at contact pin in elastic contact chip after plugging together with jack, need the space of release, therefore leave the gap on the installation length of the outer hat of design spring contact, and installation is to block by the contact pin backward step of going forward, reliability was not high when this structure was used under mal-condition.In sum, be subjected to self structure and the restriction that contacts problem such as reliable, therefore at present this outer hat spring contact can only be used on the contact pin that diameter is little in the electric connector, is used for transmitting little electric current.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, a kind ofly is installed in that contact resistance on the electric connector contact pin is little, contact is reliable, difficult deformation, can transmits the resilient contact of big electric current thereby design.
Technical solution of the present utility model: it is characterized in that being the swelling-waist shape that has opening, reach between upper side frame, the lower frame around the resilient contact and can outwards reverse and carry the waist shape reed of R fillet by several, arrange the profile of tooth sheet that has with waist shape reed equal number and relative central shaft rotating band angle at upper and lower frame two, the resilient contact external diameter is greater than the jack diameter.
Advantage of the present utility model: can be installed on the electric connector contact pin, its contact resistance is little, and contact is reliable, difficult deformation, can transmit big electric current.

Among the figure 1 is waist shape reed, the 2nd, profile of tooth sheet, the 3rd, and gap, the 4th, upper side frame, 4 ' is lower frame.
Embodiment
Contrast accompanying drawing 1,2, its structure is to be the swelling-waist shape that has opening, reaching between upper side frame, the lower frame around the resilient contact has several can outwards reverse and carry in both sides the waist shape reed 1 of R fillet, arrange the profile of tooth sheet 2 that has with waist shape reed equal number and relative central shaft rotating band angle at upper and lower frame two, the resilient contact external diameter is greater than the jack diameter.
Described waist shape reed 1 both sides have the R fillet.
It is the groove of right-angled trapezium that the anglec of rotation α of described profile of tooth sheet 2 and height h place have two cross sections, and has symmetrical arc gap.
Contrast accompanying drawing 3,4,5, resilient contact is formed behind blanking by the elasticity copper strips, forms final part again after heat treatment, surface treatment.In the blanking process, guarantee the shape of each waist shape reed 1 by gap 3.Forming process is divided into two ones: 1) waist shape reed 1 reverses β angle both sides band R circular arc simultaneously, when contact pin and jack plug together like this, each waist shape reed is adjusting angle voluntarily, guarantee that R fillet place, the outside contacts with the reliable of jack, and waist shape reed only is subjected to jack applies positive pressure in the contact position a component, causes loose contact so should not produce the fatigue deformation phenomenon in frequent plug process.Both sides band R circular arc has increased the contact area between jack, contact pin and the waist shape reed, has reduced contact resistance, has protected contact pin, socket surfaces simultaneously in contact pin and jack plug process; 2) upper and lower side frame two profile of tooth sheet 2 rotation alpha angles, the profile of tooth sheet 2 at this two is the installation end as resilient contact, contact pin is according to the α angle of resilient contact two profile of tooth sheet 2 rotation and the height h groove that to have two cross sections be right-angled trapezium, and having a symmetrical arc gap, resilient contact enters the right-angled trapezium groove by arc gap and on contact pin.This mounting structure has determined that the utility model in use has very high reliability.
Contrast Fig. 7, in the blanking process, gap 3 rotates to an angle, and the waist shape reed that blanking is with angle can reduce waist shape reed windup-degree β like this in forming process.Also can be in the blanking process waist shape reed 1 is formed among Fig. 8 arc, also can be in forming process with the overhead kick shape among profile of tooth sheet 2 one-tenth Fig. 8-1 at upper and lower side frame two.
Because the resilient contact maximum outside diameter place size that is installed on the contact pin is slightly larger than the jack size, when contact pin and jack plug together, each waist shape reed 1 is adjusting angle voluntarily, guarantee that R fillet place, the outside contacts with the reliable of jack, and 1 of waist shape reed is subjected to jack applies positive pressure in the contact position a component, causes loose contact so should not produce the fatigue deformation phenomenon in frequent plug process.
Because each waist shape reed 1 both sides has the R fillet, has increased the contact area between jack, contact pin and the waist shape reed like this, has reduced contact resistance, in contact pin and jack plug process, contact pin, socket surfaces have been protected simultaneously.
Because upper and lower side frame two row has the profile of tooth sheet 2 that certain angle is arranged with waist shape reed 1 equal number and the rotation of relative central shaft, the profile of tooth sheet 2 at this two is the installation end as resilient contact, contact pin is according to the anglec of rotation α of resilient contact two profile of tooth sheet 2 and the height h groove that to have two cross sections be right-angled trapezium, and having symmetrical arc gap, this mounting structure has determined that the utility model in use has very high reliability.
