The inventive direction of the touch finger of the composite watchband

Composite watchband contact finger, band connector and manufacturing method thereof. The composite watchband contact finger includes a contact finger end portion, the contact finger end portion extends a first contact finger arm and a second contact finger arm to both sides, the first contact finger arm and The second contact arm form a certain angle, the head end of the first contact arm is provided with a first embedding groove, and the bottom surface of the first embedding groove is connected with the pointed part of the contact finger and the contact arm. A plane where the first contact arm and the second contact finger arm are located has a first included angle, a head end of the second contact finger arm is provided with a second embedding groove, and a bottom surface of the second embedding groove is connected to the sharp corner of the contact finger and the first contact finger. The arm of the second contact finger has a second angle with a plane in which the arm is located. The strap connector includes at least one composite strap contact finger and a connecting strap. The mounting strip extends a distance from both sides of the connecting strip. The mounting strip on one side is embedded in the first embedding groove, and the mounting strip on the other side is embedded in the second embedding groove, and the spacing ensures that the conductive contact fingers do not collide with each other.

In the prior art, the contact fingers are connected in series to form a ribbon connector, and the ribbon connector plays an electrical connection role in the power transmission and transformation circuit. When the contact fingers of the strap connector in the prior art are squeezed, the adjacent contact fingers conflict with each other, and the contact fingers are unevenly stressed, resulting in unstable transmission current and affecting the service life of the strap connector. Ribbon connectors in the prior art are in need of improvement.


In view of the shortcomings of the prior art, the present invention provides a composite strap contact finger and strap connector and its production method, which overcomes the problem that the contact fingers of the prior art strap connector collide with each other during the extrusion process., And the force on the contact finger is uneven., The transmission current is unstable, which affects the service life of the strap connector.


The beneficial effect of the above solution is: the embedded groove of the contact finger of the present invention and the pointed part of the contact finger have an angle with the contact arm, so that the contact arm and the plug are in close contact, and the arrangement distance of the mounting strip ensures the contact fingers There will be no conflict between each other, thereby ensuring the stability of current output and improving the service life of the strap connector. The present invention also includes copper, nickel, and silver plating on the surface of the contact fingers of the composite wristband. The combination of these three metals further enhances the conductive stability of the ribbon connector.
