Description
Technical Field
The invention relates to the technical field of fingerprint module testing, in particular to a universal BTB limit connector for fingerprint module functional testing.
Background
Along with the continuous progress of science and technology, people also leave the mobile phone increasingly, most mobile phones on the market at present all possess fingerprint unlocking function, and fingerprint unlocking has safe, swift advantage, and the requirement to mobile phone fingerprint is also higher and higher, not only needs the security, and response speed is also very important, consequently before dispatching from the factory, also need carry out a large amount of tests and also adjust, need use fingerprint module test fixture.
Existing connectors use male and female sockets for snap-fit connection, and industry BTB connectors generally only guarantee at least 50 reliable connections. In general, after a female connector seat is buckled with a male connector seat of a different connector, irreversible deformation and looseness can occur, and the problem of poor connection contact of the male and female connector seats is easy to occur. When the current module factories use the BTB connector to perform functional test on the module, the module cannot be connected due to excessive buckling times of the connector female seat. Meanwhile, a large number of connector female seats are consumed in function test, each connector female seat is also required to be welded on the adapter plate manually or mechanically, and a large amount of consumption is also caused on the adapter plate.
In addition, because the BTB connector is small in size, time is required for alignment and then buckling during manual operation, and a large amount of time is consumed.
Disclosure of Invention
The invention aims to provide a general BTB limit connection jig for a fingerprint module, which comprises a fingerprint identification module, a base and a hinge, wherein the fingerprint identification module comprises an identification module body and a fingerprint module connector, the tail end of the fingerprint module connector is provided with a connector joint, the hinge is hinged with the base, and the side surface of the base is provided with a PCB; a spring probe is arranged in the base and connected with the PCB, and the spring probe is matched with the connector joint; the spring probe upper portion is provided with a spacing connector, still be provided with a spacing recess on the spacing connector, be provided with the opening on the spacing recess, spacing recess with connector joint looks adaptation.
Preferably, the openings are a plurality of holes, and the holes are in one-to-one correspondence with the probes of the spring probes. The spring probes comprise a plurality of metal probes, and after the connector is aligned with the limit groove and pressure is applied to the connector (the hinge gives pressure), the metal probes can correspondingly extend out of holes of the limit groove to be connected with the connector.
As a preferable scheme, one side of the hinge is provided with a spring buckle, and the base is provided with a groove matched with the spring buckle. After the hinge is pressed down, a user can buckle the hinge to the groove on the base through the overturning spring so as to fix the hinge, and the purpose of fixing the connector and the spring probe for a long time is achieved.
As a preferable scheme, one end of the limiting connector is connected with the base through a spring. The limiting connector is connected with the base through the spring, so that the limiting connector can move in the vertical direction, and when the hinge is in contact with the limiting connector, the spring probe at the lower part of the limiting connector can be better conducted with the connector of the fingerprint module.
As a preferable scheme, the hinge is connected with the base through a torsion spring. Through torsional spring connection hinge and base, only need upset hinge can be better fixed/separation connector and spring probe, the connected mode of hinge and base also can be modes such as telescopic link, but the connected mode of torsional spring is more easy to use, and the life-span is longer.
As a preferable scheme, the hinge is also provided with a lug, and the position of the lug is matched with the limit connector. The connector joint is fixed to the limiting groove in a bump contact mode, so that materials used for the hinge can be effectively reduced on the premise of maintaining the pressure unchanged, and the quality of the hinge is reduced.
As the preferable scheme, the base and the hinge are made of steel materials and aluminum materials, the surface of the base and the hinge is subjected to paint spraying, the limit connector is made of aluminum alloy materials, and the surface of the limit connector is coated with insulating paint. The spacing connector is required to be insulated as a component that needs to be in contact with the spring probe and the connector.
As a preferable scheme, the periphery of the limit groove is designed with a bevel edge. Through the design of hypotenuse, when the operator put into spacing recess with the connector joint, can the automatic alignment spacing spring probe of recess bottom.
The technical scheme has the following beneficial technical effects:
1) According to the invention, the spring probe is used for contacting the metal contact of the male seat of the connector, so that the metal contact of the male seat is not damaged while the connection effect is ensured, and the connection reliability is improved;
2) According to the invention, through the limit design, the time consumed by aligning the connector is greatly reduced, and the operation efficiency is improved;
3) The spring probe used in the invention is a common general spring probe with specific specification, has mature technology, high reliability and long service life beyond the buckling service life of the BTB connector, thus reducing a great amount of waste of the current functional test on the connector female seat and the adapter plate;
4) Before improvement, a large number of adapter plates and connector female seats are required to be welded in a time consuming manner, and after the welded adapter plates are used for tens of times, the problem of poor contact occurs, so that the problem of connection of the connectors or the functional problem of the module cannot be confirmed. When the connector jig is used for fastening, the positions are aligned to press fastening, and if the reason is not confirmed through one test, the connector jig is required to be fastened for multiple times, and after the special connector jig is manufactured, quick, nondestructive and reliable connection can be realized.
