Description
Technical field
The utility model belongs to art of electrical connectors field, and in particular to a kind of U-shaped contact pin.
Background technique
Row's needle connector is a kind of common electric power connector, is widely used on pcb board card.Row's needle connector is set
During meter, generally under the premise of meeting performance indicator, simple structure and fixed form are used as far as possible, it is good in the hope of reaching
Economic benefit.Production process is to be inserted into pedestal by manually or automatically board by needle is arranged, and group founds needle connector in a row.
Existing row's wire surface is flat and smooth structure design, and row's needle connector is when crossing wave-soldering, since row's needle is
Metal material, pedestal are plastic cement materials, and the cold and hot coefficient of the two is inconsistent, therefore it is easy to appear the feelings that row's needle is loosened from pedestal
Condition；And row's the anticorrosive of needle, oxidability is poor, and service life is lower.Thus it is proposed that a kind of U-shaped contact pin.
Utility model content
The purpose of this utility model is to provide a kind of U-shaped contact pins, to solve to propose existing row in above-mentioned background technique
Wire surface is flat and smooth structure design, and for row's needle connector when crossing wave-soldering, since row's needle is metal material, pedestal is modeling
The cold and hot coefficient of glue material matter, the two is inconsistent, therefore it is easy to appear row's needles from the case where pedestal loosening；And arrange the anti-corruption of needle
Erosion, oxidability are poor, the lower problem of service life.
To achieve the above object, the utility model provides the following technical solutions: a kind of U-shaped contact pin, including U-shaped metalwork,
Bright tin layers and two spacing block sets are respectively arranged on the outside of the U-shaped metalwork, the spacing block set is located at the outer of bright tin layers
Side is symmetrically arranged with circular platform type fixed block at the top of the U-shaped metalwork, and the upper surface of the circular platform type fixed block is provided with copper
Coating, and electroless nickel layer is provided on the outside of the circular platform type fixed block.
Preferably, the electroless nickel layer with a thickness of 2-3um, the bright tin layers with a thickness of 5-8um.
Preferably, it is an integral molding structure between the circular platform type fixed block and U-shaped metalwork.
Preferably, the material of the U-shaped metalwork is E-CU58ETP1, and the tensile strength of the U-shaped metalwork is
300-400N/mm2。
Preferably, the spacing block set is in square type structure, and solid by welding between the spacing block set and U-shaped metalwork
It is fixed.
Compared with prior art, the utility model has the beneficial effects that the utility model passes through in the outside of U-shaped metalwork
It is symmetrically arranged with spacing block set, prevents from connecting loosening between U-shaped metalwork and pedestal, by setting on the outside of circular platform type fixed block
Set electroless nickel layer, play the role of it is erosion-resisting, by the way that bright tin layers are arranged in the outside of U-shaped metalwork, play the role of it is oxidation resistant,
Service life increases.
