Description
Technical field
The present invention relates to electric connector fields, bend font Elastic Contact reed particularly to a type.
Background technology
Electric connector is the common components of electric signal transmission, is not only, in industries such as communication, power transmissions, nowadays navigating
Extremely wide application has been obtained in the fields such as its aviation.Between some special occasions, the contact of electric connector not
Be using conventional inserting mode, but the elasticity pressure used touch by the way of transmission telecommunications number, this type electric connector is often use
In the switching of electric signal, including panel, panel is equipped with penetrating mounting hole, elastic contact, contact in mounting hole
Both ends be respectively formed contact site, contacted when in use with component elasticities such as the conductive plates of mating electrical connector and realize electricity
The switching of signal.
Above-mentioned in the electric connector of signal converting, common contact type mainly to have following three kinds：1st, c-type；
2nd, V-type；3rd, screw type.The structure of C-shaped contact is as shown in Figure 1, it includes the arc-shaped contact part at both ends and is connected to two
Connecting portion between contact site, connecting portion is substantially in tabular, and when in use, the position that elastic shape plate occurs is often
At crossover position between contact site and connecting portion, deformation position is not only few, but also deformation range is smaller, therefore is easy to out
The problem of existing fatigue damage；The structure of V-type contact is as shown in Fig. 2, it is equally using both ends as contact site, compared to above-mentioned V
For type contact spring, deformation position when in use is more concentrated, and deformation range is smaller, therefore is also more prone to fatigue
Damage；Helix-style contact part is without the slice structure using above-mentioned c-type, V-arrangement contact, therefore service life is relatively long, but
It is that it but has material high requirement, common common copper material tends not to provide enough elastic contact forces, and spiral shell
The loop inductance of rotation type contact is larger, is unfavorable for the high-quality transmission of signal.
As can be seen from the above description, the contact of reed-type is there is the problem of fatiguability damage, though helix-style contact part
So the fatigable problem of reed-type contact is overcome, but the requirement to material is excessively harsh, it is of high cost there is manufacturing
The problem of.
Invention content
The purpose of the present invention is to provide a types to bend font Elastic Contact reed, to solve reed-type contact fatiguability
The problem of damage.
To solve the above-mentioned problems, class of the invention bow font Elastic Contact reed uses following technical scheme：Class bends word
Shape Elastic Contact reed, two contact sites including both ends and the connecting portion being connected between two contact sites, contact site is arc-shaped,
The connecting portion takes the shape of the letter U, and is connected between contact site and connecting portion by arc transition, and connecting portion is formed " bow " together with contact site
Character form structure.
The both ends of the connecting portion are gradually drawn close mutually.
The lateral surface of the wall for the U-shaped that the connecting portion is formed and the transition position at bottom forms the end for bearing contact portion
The bearing surface at end.
Deformation resigning gap is equipped between the end of contact site and corresponding bearing surface.
Since the connecting portion of the class bow font Elastic Contact reed of the present invention takes the shape of the letter U, pass through between contact site and connecting portion
Arc transition connects, and connecting portion forms " bow " character form structure together with contact site, therefore, in use, when contact site and
When intermateable connector contact is pressurized, such bow font Elastic Contact reed should at least have it is following can deformation position：Connecting portion
Portion at the close connecting portion of the knee of the U-shaped formed, the transition position of two contact sites and connecting portion and contact site in itself
The fatigue of contact spring so as to greatly disperse its bending stress when being pressurized, is slowed down in position.It can be seen that the present invention
Class bow font Elastic Contact reed solves the problems, such as the damage of reed-type contact fatiguability.
Further, it is deformation position in order to when guiding the contact spring to be pressurized that the both ends of connecting portion is made, which gradually to draw close mutually,
It puts, to ensure that it can be bent according to the position of setting and range；The setting of bearing surface is the deformation in order to limit contact spring
Amplitude avoids it due to excessive deformation and tired.

Specific embodiment
Class bends the embodiment of font Elastic Contact reed, and as Figure 4-Figure 6, such bow font Elastic Contact reed includes two
Two contact sites 11 at end and the connecting portion 12 being connected between two contact sites 11.
Contact site 11 is arc-shaped, and in the present embodiment, contact site 11 is specifically to be arc-shaped, when in use, contact
The lateral surface on the arc top in portion 11 can be as the contact surface contacted with intermateable connector.
Connecting portion 12 takes the shape of the letter U, in the present embodiment, the U-shaped and off-gauge U-shaped that connecting portion 12 is formed, specifically,
Be because gradually being drawn close mutually between the both ends of connecting portion 12 so that it in substance forms the U-shaped of closing in trend, this
Sample design is on the one hand to guide bending position of the connecting portion 12 when both ends are pressurized, and is on the other hand to increase its bending
Range forms extremely gently because gradually being tilted between the both ends of connecting portion 12 and drawing close actually also to tilt at it at start bit
Warp architecture.It is connected between contact site 11 and connecting portion by arc transition, connecting portion forms " bow " word together with contact site
Shape structure.In the present embodiment, the end of contact site 11 extends to the position for the bottom that will be close to connecting portion 12, and such one
Come, be under pressure in contact site 11, when entire contact spring deforms upon, then the end of contact site 11 withstands on connecting portion and formed
U-shaped wall and bottom transition position lateral surface at, so as to limit the deformation quantity of contact spring, prevent its excessive deformation,
So that the lateral surface of the transition position of the wall and bottom for the U-shaped that connecting portion is formed is formd for the end in bearing contact portion
Bearing surface 13, the gap between the end of contact site and corresponding bearing surface forms the deformation resigning gap 14 of contact site.
In the other embodiments of class bow font Elastic Contact reed, connecting portion can also be the U-shaped of C-shaped or standard,
Contact site can also be ellipse arc, in short, connecting portion and contact site integrally can deformation of dispersing contact reed when being pressurized should
Power.
