Abstract

The invention relates to the field of electrical connectors, in particular to a bow-like elastic contact spring comprising two contact portions arranged at two ends and a connection portion connected between the contact portions; the contact portions are arc shaped; the connection portion is U shaped; the contact portions are in arc transitional connection with the connection portion; the connecting portion and the contact portions jointly form a bow structure. When the contact portions are in contact with an adapter and stressed during usage, the bow-like elastic contact spring needs to deform with parts: a U bend of the connection portion, transitional parts of the contact portions and the connection portion, and the parts, close to the connection portion, of the contact portions; thus, bending stress can be greatly spread when the spring is under stress, and fatigue of the spring is relieved. Therefore, by the use of the bow-like elastic contact spring, the problem that the spring contactor is easily damaged by fatigue is solved.

Description

Class bow font Elastic Contact reed
Technical field
The present invention relates to electric connector field, particularly relate to a kind bow font Elastic Contact reed.
Background technology
Electric connector is the common components of electric signal transmission, and be not only in industries such as communication, electric power transfer, nowadays it all obtain and apply very widely in the fields such as space flight and aviation.In the occasion that some are special, not adopt conventional inserting mode between the contact of electric connector, but the mode transmission of electric signals that the elasticity pressure adopted is touched, this type electric connector is often for the switching of the signal of telecommunication, it comprises panel, and panel is provided with penetrating installing hole, the contact of installing hole Elastic, the two ends of contact form contact site respectively, contact and realize the switching of the signal of telecommunication when in use with component elasticity such as the conductive plates of mating electrical connector.
Above-mentioned in the electric connector of signal converting, conventional contact type mainly contains following three kinds: 1, C type; 2, V-type; 3, spiral type.The structure of C shape contact as shown in Figure 1, it arc-shaped contact part comprising two ends place and the connecting portion be connected between two contact sites, connecting portion is substantially in tabular, when in use, there is the crossover position place of position often between contact site and connecting portion of elasticity shape plate, deformation position is not only few, and deformation range is less, is therefore easy to the problem occurring fatigue damage; As shown in Figure 2, it is be contact site with two ends to the structure of V-type contact equally, compares to above-mentioned V-type contact spring, and its deformation position is in use more concentrated, and deformation range is less, is therefore also more prone to fatigue damage; Helix-style contact part does not adopt the slice structure of above-mentioned C type, V-arrangement contact, therefore useful life is relatively long, but it but has high requirement to material, common common copper material often can not provide enough elastic contact force, and the loop inductance of helix-style contact part is comparatively large, be unfavorable for the high-quality transmission of signal.
Known by describing above, the contact of reed-type also exists the problem of fatiguability damage, although helix-style contact part overcomes the fatigable problem of reed-type contact, but too harsh to the requirement of material, there is the problem that manufacturing cost is high.
Summary of the invention
The object of the present invention is to provide a kind bow font Elastic Contact reed, to solve the problem that reed-type contact fatiguability damages.
In order to solve the problem, class of the present invention bends font Elastic Contact reed by the following technical solutions: class bow font Elastic Contact reed, two contact sites comprising two ends and the connecting portion be connected between two contact sites, contact site is curved, described connecting portion takes the shape of the letter U, be connected by arc transition between contact site with connecting portion, connecting portion is formed together with contact site " bow " character form structure.
The two ends of described connecting portion are drawn close mutually gradually.
The wall of the U-shaped that described connecting portion is formed and the lateral surface of the transition position at the end form the bearing-surface of the end for bearing contact portion.
Be provided with deformation between the end of contact site and corresponding bearing-surface to step down gap.
Because the connecting portion of class bow font Elastic Contact reed of the present invention takes the shape of the letter U, be connected by arc transition between contact site with connecting portion, connecting portion is formed together with contact site " bow " character form structure, therefore, in use, when contact site contacts pressurized with intermateable connector, such bow font Elastic Contact reed should at least have following can deformation position: the knee of the U-shaped that connecting portion is formed, the position at the close connecting portion place of the transition position of two contact sites and connecting portion and contact site itself, thus its bending stress when pressurized can be disperseed widely, slow down the fatigue of contact spring.As can be seen here, class bow font Elastic Contact reed of the present invention solves the problem that reed-type contact fatiguability damages.
Further, the two ends of connecting portion are drawn close mutually be gradually the deformation position in order to guide during contact spring pressurized, to ensure that it can bend according to the range and position of setting; The setting of bearing-surface is the deformation amplitude in order to limit contact spring, avoids it tired due to excessive deformation.

Embodiment
The embodiment of class bow font Elastic Contact reed, as Figure 4-Figure 6, two contact sites 11 that such bow font Elastic Contact reed comprises two ends and the connecting portion 12 be connected between two contact sites 11.
Contact site 11 is curved, and in the present embodiment, contact site 11 is specifically in circular arc, and when in use, the lateral surface on the arc top of contact site 11 can as the contact-making surface contacted with intermateable connector.
Connecting portion 12 takes the shape of the letter U, in the present embodiment, the U-shaped that connecting portion 12 is formed off-gauge U-shaped, specifically, because draw close mutually gradually between the two ends of connecting portion 12, it is made in substance form the U-shaped of closing in trend thus, such design is on the one hand the bending position in order to guide connecting portion 12 when two ends pressurized, being to increase its bending range on the other hand, in fact also defining very mild warp architecture at its inclination start bit place because tilt to draw close gradually between the two ends of connecting portion 12.Contact site 11 is connected by arc transition with between connecting portion, connecting portion is formed together with contact site " bow " character form structure.In the present embodiment, the end of contact site 11 extends to the position of the bottom be about near connecting portion 12, so, be under pressure at contact site 11, during whole contact spring generation deformation, then the end of contact site 11 withstands on the lateral surface place of the wall of the U-shaped that connecting portion is formed and the transition position at the end, thus the deformation quantity of contact spring can be limited, prevent its excessive deformation, the wall of U-shaped making connecting portion be formed thus and the lateral surface of the transition position at the end define the bearing-surface 13 for the end in bearing contact portion, the deformation that gap between the end of contact site and corresponding bearing-surface defines contact site is stepped down gap 14.
In other embodiment of class bow font Elastic Contact reed, connecting portion can also be the U-shaped of C shape or standard, and contact site can also be ellipse arc, in a word, connecting portion and contact site entirety can dispersing contact reed pressurized time deformational stress.
