Abstract

The utility model discloses a low-loss contact pair for an electric connector, which consists of a rigid anode contact element and an elastic cathode contact element, wherein the rigid anode contact element and the elastic cathode contact element are mutually matched for working. The low-loss contact pair is characterized in that the elastic cathode contact element is in a wave-shaped structure, and at least two contact points are formed at one side of the elastic cathode contact element in contact with the rigid anode contact element. The low-loss contact pair for the electric connector has the low-loss characteristic under the high-frequency condition and simultaneously also has the advantages that the structure is simple, the manufacture cost is not increased, the contact is reliable, the deformation is little, and the like.

Description

Electric connector is right with the low-loss contact
Technical field
The utility model relates to the connector technique field, and it is right with low-loss contact to be specifically related to a kind of electric connector.
Background technology
Bearing the electric connector of the communication apparatus of transmission signals, particularly high transmission speed in communication field uses more and more.The specification demand of following high-speed differential signal, after allowing to stride across 64/66 bits of encoded from 10Gb/s to 25Gb/s(, technical is 25.8Gb/s), can allow that corresponding 100Gb/s has the link narrower than 4X25Gb/s on the backboard.For satisfying the 25Gb/s transmission rate, the smaller the better to the loss requirement of the electric connector in the transmission link, so low-loss electric connector plays an important role in high speed transmission of signals.
As shown in Figure 1, the right structure of contact of existing electric connector makes its loss excessive (as shown in Figure 3) to be difficult to satisfy the demand of low-loss connector.
For solving the aforementioned problems in the prior, the utility model provides a kind of new solution.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of electric connector right with the low-loss contact, this electric connector with low-loss contact under the high-frequency condition, having low loss characteristic, also have simultaneously simple in structure, do not increase advantages such as manufacturing cost, contact is reliable, distortion is little.
For achieving the above object, the technical scheme that the utility model adopted is: provide a kind of electric connector right with the low-loss contact, be made up of the rigidity male contact and the elasticity female contact of the work of cooperatively interacting; It is characterized in that: described elasticity female contact undulate structure forms at least two contact points with the contacted side of rigidity male contact on the elasticity female contact.
Described contact point is provided with 3.Distance between the adjacent described contact point equates.
In sum, electric connector provided by the utility model with low-loss contact to than existing contact to having following advantage: 1, simple in structure, do not increase manufacturing cost; 2, the right contact point of contact increases, and has increased the reliability of contact; 3, to have shared contact stressed for multiconductor, and male contact is stressed evenly, is out of shape little; 4, count by increasing the contact of contact centering, reduced contacting right antenna effect, reach the radiation loss that reduces energy.
Description of drawings
Fig. 1 is the right structural representation of existing contact;
Fig. 2 is the right structural representation of low-loss contact of the present utility model;
Fig. 3 is that existing contact is to simulation calculation loss schematic diagram;
Fig. 4 is that low-loss contact of the present utility model is to simulation calculation loss schematic diagram.
Wherein, 1, rigidity male contact; 2, elasticity female contact; 3, contact point.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
As shown in Figure 2, this electric connector contacts being made up of the rigidity male contact 1 and the elasticity female contact 2 of the work of cooperatively interacting with low-loss; Described elasticity female contact 2 undulate structures form three contact points 3 with rigidity male contact 1 a contacted side on the elasticity female contact 2.Distance between the adjacent described contact point 3 is unequal mutually.
Described elasticity female contact 2 adopts the wave shaped structure, on elasticity female contact 2 with in plugging consistent direction, increase contact point 3, each contact of electric connector is to the last contact point 3 that all has more than 2 or 2, feasible full contact to contact area, also reduced simultaneously the extension elongation of rigidity male contact 1, when high speed transmission of signals, reduced the antenna effect of rigidity male contact 1, thereby make the loss of signals transmission energy reduce, realize that more low-loss contact is to structure, as shown in Figure 4.
The utility model is not limited to above-mentioned example, in claims of the present utility model institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
