Description
Technical field
Technical field of electric connectors is the utility model is related to, especially a kind of knot of high reliability leaf spring formula jack contact
Structure.
Background technology
Traditional jack contact is broadly divided into leaf spring formula jack, hat spring formula jack and wire spring type jack.Wherein leaf spring formula
For jack because low processing cost is widely used, the leaf spring formula jack of prior art is along axle on the barrel wall of jack
To the telescopic chute for being provided with several insertion, barrel wall is circumferentially divided into several jack strips, during use by jack strip from
The elasticity of body ensures the contact strength with butt end, so as to realize the normal transmission of electric signal.The problem of existing is jack strip
Elastic force and elastic deformation be limited in scope, in use, because the assembling of butt end is improper, the deformation of jack strip once exceeds
The scope of elastic deformation, then jack strip will lose the ability for recovering deformation, the contact strength of jack strip and butt end is natural
Failure, cause loose contact or even the breaking phenomena of circuit occurs, the normal transmission of electric signal can not be realized.
Utility model content
A kind of high reliability leaf spring formula jack that the purpose of this utility model is in view of the shortcomings of the prior art and provided connects
The structure of contact element, the utility model on leaf spring formula jack using lock sleeve is provided with, when the column of butt end inserts cylinder
Leaf spring formula jack in, under the elastic force of jack contact piece itself and lock sleeve elastic force double action, jack contact piece collapse will
Butt end locking, completes the connection of the utility model and butt end, the utility model have contact area is big, bonding strength is high,
The advantages of functional reliability height and long service life.
Realizing the concrete technical scheme of the utility model purpose is：
A kind of structure of high reliability leaf spring formula jack contact, its feature includes leaf spring formula jack and lock sleeve, described
Leaf spring formula jack is the cylindrical member that one end is provided with cylinder, the groove of depression is radially provided with its barrel wall, on barrel wall along axle
To the telescopic chute penetrated provided with several, the lock sleeve is the tubular elastic component for being axially arranged with otch；The lock sleeve is sleeved on
In the groove of leaf spring formula jack；The barrel of described leaf spring formula jack cylinder is divided into several pieces jack contact pieces by telescopic chute；Institute
The otch for the lock sleeve stated is straight line or broken line.
The utility model on leaf spring formula jack using lock sleeve is provided with, when the column of butt end inserts the piece of cylinder
In spring formula jack, under the elastic force of jack contact piece itself and lock sleeve elastic force double action, jack contact piece collapses will docking
Locking is held, completes the connection of the utility model and butt end, the utility model has that contact area is big, bonding strength is high, work
The advantages of reliability height and long service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of leaf spring formula jack；
Fig. 3 is the structural representation of lock sleeve；
Fig. 4 is use state diagram of the present utility model.
Embodiment
Refering to Fig. 1, Fig. 2, Fig. 3, the utility model includes leaf spring formula jack 1 and lock sleeve 2, and the leaf spring formula jack 1 is
One end is provided with the cylindrical member of cylinder, and the groove 11 of depression is radially provided with its barrel wall, is provided with several vertically on barrel wall
The telescopic chute 12 of insertion, the lock sleeve 2 are the tubular elastic component for being axially arranged with otch 21；The lock sleeve 2 is sleeved on leaf spring
In the groove 11 of formula jack 1；The barrel of the described cylinder of leaf spring formula jack 1 is divided into several pieces jack contact pieces by telescopic chute 12
13；The otch 21 of described lock sleeve 2 is straight line or broken line.
The utility model so uses：
The utility model and the connection of butt end：Refering to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model is connected with butt end 3
The contact pair of electric connector is formed, butt end 3 is column, and during work, lock sleeve 2 is sleeved on into leaf spring formula jack 1 first
In groove 11, then the column of butt end 3 inserted in the leaf spring formula jack 1 of cylinder, in the jack contact piece 13 of leaf spring formula jack 1
Under the elastic force of itself and the elastic force double action of lock sleeve 2, jack contact piece 13 is collapsed the locking of butt end 3, completes electrical connection
The utility model of device and the connection of butt end 3.
Technique effect caused by the utility model connection：
Refering to Fig. 1, Fig. 3, Fig. 4, the utility model uses the otch 21 of lock sleeve 2 as the design of straight line or broken line, can be with
Change the coupling mechanism force of lock sleeve 2, to meet the needs of different occasion the utility model are from 3 different coupling mechanism forces of butt end.
Refering to Fig. 1, Fig. 4, due to lock sleeve 2 to be axially arranged with the tubular elastic component of otch 21, lock sleeve 2 is sleeved on leaf spring
In the groove 11 of formula jack 1, when the column of butt end 3 is inserted in the leaf spring formula jack 1 of cylinder, inserted in leaf spring formula jack 1
Under the elastic force of hole contact chip 13 itself and the elastic force double action of lock sleeve 2, several pieces jacks of the cylinder of leaf spring formula jack 1 are forced to connect
Contact 13 is collapsed, and the column of butt end 3 is embraced into tighter, the jack contact piece 13 of leaf spring formula jack 1 and the column of butt end 3
Effective contact area increase between body, bonding strength improve, and more conform to the working characteristics of high current contact pair.
Refering to Fig. 1, Fig. 4, jack contact piece 13 on the cylinder of the utility model leaf spring formula jack 1 is not required to close up when making,
Bending, due to being additionally arranged lock sleeve 2, even if the spring function failure of jack contact piece 13, nor affects on the jack of leaf spring formula jack 1
The contact with the column of butt end 3 of contact chip 13, greatly improves functional reliability and service life of the present utility model.
