Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, provides that a kind of structure is simple, cost of manufacture is low, the card connector contact of stable connection.
For solving the above-mentioned defect of prior art, the technical scheme that the utility model provides is: a kind of card connector contact, comprise connection substrate, the side of described connection substrate is provided with a groove, the middle part of described groove is provided with a junction, the upper end of described connecting portion extends upward contact Rotating portion on, and the lower end of described connecting portion extends contact Rotating portion downwards, and the end in described upper contact Rotating portion is connected by a contact arm with the end in described lower contact Rotating portion.
One as the utility model card connector contact is improved, described contact arm two ends be respectively equipped with an extension, one of them extension is connected with described upper contact Rotating portion, and another extension is connected with described lower contact Rotating portion.
One as the utility model card connector contact is improved, and the middle part of described contact arm bends out a projection.
One as the utility model card connector contact is improved, and the shape of described projection is any one of U-shaped, semicircle, V-arrangement or mentioned ridge-shaped.
One as the utility model card connector contact is improved, and described contact arm and described upper contact Rotating portion and described lower contact Rotating portion are connected to form a C shape.
One as the utility model card connector contact is improved, described upper contact Rotating portion and have certain gap between described lower contact Rotating portion and described connection substrate.
One as the utility model card connector contact is improved, and described connection substrate is provided with an installation portion.
One as the utility model card connector contact is improved, described extension, described contact arm and described contact Rotating portion are positioned at the top of described installation portion, and the stressed strain in described extension, contact arm and upper contact Rotating portion and lower contact Rotating portion moves down.
Compared with prior art, the utility model has the advantages that: the contact that the utility model adopts is formed by the stamping-out of one piece of metal plate and bending machining, processes relative cylinder list; Contact arm and upper contact Rotating portion and lower contact Rotating portion are connected to form a C shape, the middle part of contact arm bends out a projection, the shape of projection can be varied, the pressing of card that contact arm is inserted into and strain time, the extension of contact arm and upper and lower contact arm rotating part together stress deformation move, make that the elasticity of contact arm is better, displacement is larger, the performance of contact is promoted.The most important thing is, this card connector contact has anti-snagging dog, and anti-sticking is suspended to the end of contact and the advantage damaged.
Accompanying drawing explanation
