Abstract
The utility model provides a terminal connector. The terminal connector solves the problems that the contact between a contact pad of the existing terminal connector and a plug is poor; temperature rise is high; a clamping force is unstable; insertion and extraction forces are large and unstable; the contact pad has large wear amount and is easy to deformation; and the stability of the connector is affected. The terminal connector comprises the contact pad, a plane part and a bending part. The contact pad is parallel to the plane part and is located between the plane part and the free end of the bending part. A surface contact spring is located between the contact pad and the free end of the bending part. A contact plate of the surface contact spring contacts the contact pad. Deformation plates of the surface contact spring contact the free end of the bending part. The area of the contact between a contact wall of the surface contact spring and the contact pad is large. Both ends of the surface contact spring are bent with the back to the contact pad to form elastic walls. When the plug is inserted into a gap in the middle of the contact pad, a spacing mechanism imposes pressure on the elastic walls of the surface contact spring. Pressure is equally distributed on the contact wall. A force imposed by the surface contact spring on the contact pad is equally distributed, which avoids the deformation of the contact pad.
Description
Technical field
The utility model relates to a kind of terminal connector, is specifically related to a kind of terminal connector that can contact with plug face.
Background technology
Existing bonder terminal, comprise planar portions, the lower end of planar portions is connected with terminals, the two ends, left and right of planar portions are bent to form respectively kink in opposite directions, the free end of kink and the spacing of planar portions are less than the thickness of plug, when the space between plug insertion planar portions and kink free end, plug closely cooperates with planar portions under the effect of kink elastic force.
There is following shortcoming in this structure: when the space between plug insertion planar portions and kink free end, plug one side and planar portions close contact, the contact of formation face, the free end close contact of another side and kink forms the line contact, makes the power that is distributed on plug inhomogeneous, and affect negotiability, increase the resistance of circuit, the terminal connector heating even can produce electric spark or it is burnt.Plug for a long time not only easily causes the kink distortion, makes the contact engaging and separating force of terminal connector reduce, and the stability of connection reduces.
Therefore, existing product obviously exists loose contact, temperature rise, chucking power is unstable, contact engaging and separating force is large and unstable, the plug wear extent is large, damage (can not be selected the material of overlay coating greatly, what use now is solid material, cost is high), and the production technology of this structure is high, easily produces site error.
Summary of the invention
The purpose of this utility model is: a kind of terminal connector is provided, solved the contact of existing terminal connector and plug loose contact, temperature rise, chucking power is unstable, contact engaging and separating force is large and unstable, and the contact wear extent is large, yielding, affects the problem of terminal connector stability.
Technical solution of the present utility model is:
a kind of terminal connector, comprise planar portions, the lower end of planar portions is connected with terminals, the two ends, left and right of planar portions are bent to form respectively kink in opposite directions, also comprise a contact and face contact spring, described contact spring comprises contact plate and the deformed plate that bends in opposite directions from the two ends of contact plate, contact plate and deformed plate are integrated part, described contact is parallel with planar portions and between the free end of planar portions and kink, described contact spring is between the free end of contact and kink, the contact plate of described contact spring contacts with contact, the deformed plate of described contact spring contacts with the free end of kink.
Two deformed plates of face contact spring are crooked in opposite directions, and the free end of two deformed plates does not contact mutually and do not contact with contact plate, and described contact spring cross section is " C " shape.
Two deformed plates on contact plate the projection sum and the contact plate length ratio less than 2/3.
The free end of two deformed plates is all crooked to contact plate and contact with deformed plate, and described contact spring cross section is " B " shape.
The projection sum of two deformed plates on contact plate is slightly less than contact plate length.
Two deformed plates of face contact spring are crooked in opposite directions, and the free end of described two deformed plates overlaps each other, and described contact spring cross section is " D " shape.
The cross section of kink is semicircular arc or half rectangle.
The utility model has the advantage of:
(1) the contact wall of face contact spring is parallel with contact, make the face contact spring contact with the contact face, contact plate is long-pending large, the two ends of face contact spring contact dorsad are bent to form elastic wall, when plug inserted space in the middle of contact, the elastic wall of position-limit mechanism opposite contact spring produced pressure, and pressure is evenly distributed on the contact wall, the face contact spring is evenly distributed the active force of contact, has avoided the distortion of contact.
(2) material of contact can be selected the copper of conductive resistance minimum or select the material of overlay coating, has material soft, and inelastic characteristics greatly reduce cost.
