Description
Technical field
The present invention relates to technical field of electric connectors, the elastic assembling structure of especially a kind of contact.
Background technology
The type of attachment of contact and pedestal is divided into detachable and non-dismountable two kinds of formula in traditional connector, removable
The connection for unloading formula contact tail end and wire is mostly compression joint type, and the connection of non-dismountable formula contact tail end and wire is mostly to weld
Formula.For welded type, it is mainly used in the occasion that electric current is smaller, heating is less, otherwise overheating effect easily causes scolding tin to melt
Change, easily cause rosin joint, short circuit, in actual application, the phenomenon that the damage of individual contacts part occurs due to connector is difficult to keep away
Exempt from, once occurring, welded type product can only take integral replacing connector, and not only replacement cost is high, and cumbersome, replacing
Time is grown.Due to compression joint type product high fever occasion using when without soldering melt cause rosin joint, short circuit risk, so, it is removable
The connector for unloading formula contact is promoted, for ease of dismounting, in addition to the connection of contact and wire is compression joint type, it is necessary to
Elastic support ring is set between contact and pedestal, elastic support ring it is whether rational in infrastructure, directly affect between contact and pedestal
Electrical property and connector application effect.The elastic support ring of prior art by locking plate turn up or varus in the form of be divided into it is outer support or it is interior
The problem of supportting two kinds of structures, existing is no matter outside support or inner support structure, unidirectionally can only be restricted between contact and pedestal after assembling
Axial displacement, when causing to work under vibration environment, contact loosens with pedestal, or is come off out of pedestal, causes to connect
Reliability reduction is connect, in addition, space-consuming to be also present larger for the structure, contact can not be adapted to and arrange and arrange close by type spectrum
The product of collection.
The content of the invention
A kind of elastic assembling structure for contact that the purpose of the present invention is in view of the shortcomings of the prior art and provided, this hair
The bright structure using the setting support spring circle between pedestal and contact, the elastic connection between contact and pedestal is realized, that is, is connect
Contact element and the elastic connection of component or circuit board, define bi-directional axial displacement of the contact in base into contact part hole, have
Have that connection is reliable, space-consuming is smaller, contact can independent maintenance, the advantages of being conveniently replaceable.
Realizing the concrete technical scheme of the object of the invention is：
A kind of elastic assembling structure of contact, its feature include pedestal, support spring circle and contact, and the pedestal is provided with
Several contact holes, boss are radially provided with contact holes, boss both sides are sequentially provided with edge after boss forward position and boss, support spring circle
For cylindrical shape, one of groove, the groove of twice half are provided with its barrel vertically, the port that cylindrical body is located at half groove is radially set
There is convex tendon, the section of convex tendon is in "eight" shape, and convex tendon both sides are sequentially provided with edge after convex tendon forward position and convex tendon, and contact sets for one end
There is the circular rod member that contact pin, the other end are provided with wire weldering cup, its middle part is interval with the first fin and the second fin successively；
Between the first fin and the second fin of contact, support spring circle is plugged on the support spring snare together with contact
In the contact holes of pedestal, and after the second fin of contact and the boss of pedestal along touch, after the convex tendon of support spring circle along and base
The boss forward position of seat is touched；
Along being above equipped with chamfering behind boss forward position and boss in described contact holes；First is convex on described contact
Chamfering is equipped with rib and the second fin.
The present invention realizes the bullet between contact and pedestal using the structure that support spring circle is set between pedestal and contact
Property connection, i.e. contact and component or circuit board elastic connection, define that contact is two-way in base into contact part hole
Axial displacement, has that connection is reliable, space-consuming is smaller, and contact can independent maintenance, the advantages of being conveniently replaceable.
