Abstract
The utility model discloses a clamping spring leaf which has a conducting contact bulge and is used for a main distributing frame, which comprises an installation end and an elastic free end. Two or more conducting contact bulges are arranged on the elastic free end, and the apex of each conducting contact bulge is positioned on a same plane. Metal gold is coated on the outer layer of the spring leaf. The utility model can effectively solve the disadvantages that the female end spring leaf of a plug-insert type interface in the prior art is easy to produce the fatigue deformation, and the contact resistance is increased, thus the contact resistance at the both mutually matching ends of the plug-insert type interface can be reduced, the contact performance is effectively enhanced, moreover, when being used for long time, even if the fatigue deformation of the spring leaf is produced, all conducting contact bulges can not be deviated from a male head, thus still guaranteeing the operation, and increasing the service life to a certain degree.
Description
Affiliated technical field
The utility model discloses a kind of clamping reed, particularly a kind of clamping reed that is used for main frame with the conduction contact projection.
Background technology
Along with the more and more prosperity of electronic product, various electronic devices come out thereupon, and the connection between the various electronic devices also becomes increasingly complex, and requires more and more higher.The plug-in interface in the application of electron trade more and more widely, plug-in interface of the prior art is varied, commonly used is: the two ends that cooperatively interact, an end are male, and an end is a female.Be provided with reed in female one end, during clamping, reed self has elasticity on the one hand, makes the two ends of mutual clamping cooperate tightr; On the other hand, reed also has the effect of conduction, and the two ends that cooperatively interact are electrically connected.At present, the reed that is used for plug in the known field all is " U " shape structure, one end is used for fixing on pedestal, the other end is the elasticity free end, its elasticity free end is provided with an arc convex closure, and on the one hand, the arc convex closure makes its plug convenient, on the other hand, the arc convex closure also makes two end in contact that cooperatively interact.Reed of the prior art all is provided with a convex closure at the elasticity free end of reed, and it contacts just some contact, the long-time use with male, reed is easy to generate fatigue deformation, can increase cooperate the contact resistance at two ends, influence contact performance, even can produce phenomenon such as loose contact.
Summary of the invention
Be easy to generate fatigue deformation at the above-mentioned female end reed of mentioning that is used for the plug-in interface of the prior art, increase shortcomings such as contact resistance, the utility model provides a kind of new reed structure, it is provided with conduction contact projection more than two or two at the elasticity of spring leaf free end, reduce its contact resistance, improved its contact performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of reed with the conduction contact projection, include installation end and elasticity free end, the elasticity free end is provided with the conduction contact projection more than two or two, and it is in the same plane that each conducts electricity the summit of contact protrusion.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Described conduction contact projection is three.
Described reed skin is coated with metallic gold.
The beneficial effects of the utility model are: the utility model can reduce the cooperatively interact contact resistance at two ends of plug-in interface, effectively improved contact performance, and, when long-time the use, even produce the fatigue deformation of reed, can not make all conduction contact projections all leave male yet, still can guarantee to use, increase its useful life to a certain extent.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 faces structural representation for the utility model.
Fig. 2 is the utility model plan structure schematic diagram.
Fig. 3 is the utility model user mode reference view.
Among the figure, 1-installation end, 2-elasticity free end, 3-conduct electricity contact projection, 4-reinforcement, 5-wiring board, 6-connecting groove.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, Fig. 1, Fig. 2 provide contour structures schematic diagram of the present utility model.The utility model is " U " shape structure, wherein, one end is an installation end 1, in use, by installation end 1 the utility model is fixedly mounted on the plastic casing matrix, installation end 1 one sides are provided with reinforcement 4, when being installed in the utility model on the plastic casing matrix, by reinforcement 4 it are gained in strength; The utility model other end is an elasticity free end 2, and during use, elasticity free end 2 is connected to the male place.Elasticity free end 2 is provided with two or more conduction contact projections 3, from in appearance, each conduction contact projection 3 is arranged stepped, the vertex position of each conduction contact projection 3 is on same plane, make the utility model in use, each conduction contact projection 3 all can contact with wiring board 5, thereby reduced the contact resistance at two ends to a certain extent, increased its contact performance, made its performance more reliable, even long-time the use, reed produces fatigue deformation, or even after being worn, can guarantee that still conduction contact projection 3 contacts with wiring board 5, has guaranteed its performance.
The utility model adopts tin bronze (QSn6.5-0.1) as base material, adopt process for stamping and forming earlier, the tin bronze material is struck out the reed expansion shape, pass through cold-extruded then, extrude a plurality of conduction contact projections at elasticity free end 2 places, further bending is processed into the reed finished form, and the utility model free end has connecting groove 6.
The utility model in use, operating state is contact back-to-back, two of corresponding setting, plug wiring board 5 in the middle of two reeds, please referring to accompanying drawing 3, Fig. 3 provides user mode reference diagram of the present utility model, understands helping.
Claims (3)
