Description

A kind of power interface connector and reed thereof

Technical field

The utility model relates to conduction connection area, particularly a kind of power interface connector and reed thereof.

Background technology

Connector (also being called contact, connector, plug and socket) typically refers to electric connector, is used to connect two active devices, transmission current or signals.Reed is that connector is finished the core part that is electrically connected function, generally is made up of positive reed and negative reed to contact rightly, finishes electrical connection by plugging together of yin, yang reed.The contact performance of power interface connector reed reliably whether, directly affect power connection.

At present, power interface connector adopts pin or sheet metal reed-type structure mostly.Wherein, the contact performance of pin connector is good, but the volume of this connector is bigger, and parts are many, complex structure, so difficulty of processing is big, the production cost height; And the volume of sheet metal leaf type connector is little, and parts are few, and structure is also simple relatively, and the processing difficulty of getting up is lower, and production cost is low.

The reed of sheet metal leaf type connector has elasticity, and the reed that is oppositely arranged is worked in coordination and power line can be compressed, and reed also has conductivity in addition, can make power connection after compressing power line.The reed of sheet metal leaf type connector mostly is flat hyperboloid structure, and as Figure 1-3, described reed comprises that body 1 and several are molded on the described body 1 and are parallel to each other and rubber-like contact plate 2; Described body 1 is made by electric conducting materials such as copper; Described contact plate 2 be tabular and with the angled inclination in plane, described body 1 place, as shown in Figure 4, the cross sectional shape of described contact plate 2 is a rectangle, wherein the A point is the contact point that described contact plate 2 contacts with power line, along with power line inserts connector gradually, some A that contact with power line formation straight line of naming a person for a particular job.Owing to contact for line between this reed and the power line, described contact plate 2 stressed concentrating, and the bending strength of the described contact plate 2 of tabular is poor again, the long-term easy deformation of using, useful life is short, in case and the reed distortion can make its elastic compression power diminish, and makes the contact performance variation of connector, influence power supply and connect.

The utility model content

For this reason, technical problem to be solved in the utility model is that the reed bending strength of prior art middle plateform snyed plate discharging spring chip connector is low, use yielding, useful life short for a long time, and a kind of bending strength height, contact performance are good, the power interface connector and the reed thereof of long service life and provide.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of reed of power interface connector comprises that body and several are molded on the described body and are parallel to each other and the rubber-like contact plate; Described contact plate and the angled inclination in plane, described body place, the contacted side of described reed and described power line is a contact side, described contact plate forms the cambered surface of outside protrusion at least on the close edge of described contact side.

In the above-mentioned reed, described cambered surface is an arc surface.

In the above-mentioned reed, the radius of described arc surface is the 0.2-0.5 millimeter.

In the above-mentioned reed, the radius of described arc surface is 0.22 millimeter.

In the above-mentioned reed, two edges of described contact plate all form cambered surface.

A kind of power interface connector with described reed comprises pedestal and two described reeds that are oppositely arranged on described base interior, and described reed comprises that body and several are molded on the described body and are parallel to each other and the rubber-like contact plate; Described contact plate and the angled inclination in plane, described body place, the contacted side of described reed and described power line is a contact side, described contact plate forms the cambered surface of outside protrusion at least on the close edge of described contact side.

Technique scheme of the present utility model has the following advantages compared to existing technology: power interface connector 1. of the present utility model and reed thereof, the contact plate of reed forms the cambered surface (ledge that is cambered surface is towards contact side) of outside protrusion at the edge near contact side, by in contact plate edge moulding cambered surface, make between contact plate and the power line and contact for cambered surface, contact area increases, and since moulding cambered surface, the bending strength and the elasticity of reed have been strengthened, make reed not yielding in long-term the use, long service life can keep excellent contact for a long time; 2. power interface connector of the present utility model and reed thereof form arc surface at the contact plate edge, can not only strengthen the bending strength and the elasticity of reed, make reed not yielding in long-term the use, long service life, contact performance is good, but also make things convenient for machine-shaping, be easy to make; 3. power interface connector of the present utility model and reed thereof, the radius of the arc surface of moulding are the 0.2-0.5 millimeter, preferably 0.22 millimeter, can strengthen the bending strength and the elasticity of reed to greatest extent, and guarantee the useful life and the contact performance of reed; 4. power interface connector of the present utility model and reed thereof, two edges at contact plate all form cambered surface, even the cambered surface at the contact plate edge that contacts with power line deforms so originally, can also use the cambered surface at an other side contact plane edge conversely, further prolong the useful life of reed, saved cost; 5. prove that through engaged test in the identical operating time, the power interface connector that the utility model provides is lower than the temperature rise of prior art products, resistance is little.
