Description

Lower double-needle elastic module

Technical Field

The utility model relates to a circuit board test equipment's technical field, in particular to lower duplex elastic module.

Background

In a general circuit board testing fixture, the specification of a lower pin point of a B2B connector is 0.12mm by 0.35mm, so that a usable probe is very small, and a contact surface of the lower pin is an arc surface and is easy to slide, so that a lower pin module commonly used by people has poor contact caused by sliding of the pin; in addition, a general DUT (tested product, consumer electronic product mainboard) has soldering flux, and a lower probe module tested for many times is easy to be dirty to cause poor contact; the two reasons can cause the misdetection rate of the circuit board test to increase.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, low in manufacturing cost, test effect is good, the precision is high and can effectively reduce the lower duplex elastic module of misdetection rate.

The utility model adopts the technical proposal that: the utility model discloses a keysets, fixed block, needle piece, connector and a plurality of probe, the connector is located on the bottom of needle piece, needle piece adaptation is installed on the fixed block, the fixed block is adorned admittedly the bottom of keysets, a plurality of the one end of probe all with the connector is connected, a plurality of the other end of probe runs through in proper order the needle piece with the fixed block and with the keysets is connected.

Furthermore, a plurality of the probes are uniformly arranged in a double-row parallel mode.

Further, a preferred scheme is that the needle block includes needle block upper portion and needle block lower part, be equipped with on the fixed block with needle block upper portion looks adaptation's mounting groove, needle block upper portion is located on the mounting groove, needle block lower part stretch out in the lower surface of fixed block.

Further, the upper part of the needle block and the lower part of the needle block are integrally formed, and the appearance of the needle block is T-shaped.

Furthermore, the connector is provided with a plurality of needle points corresponding to the probes one to one, the adapter plate is provided with a plurality of needle holes corresponding to the probes one to one, one ends of the probes are installed on the needle points in one to one correspondence, and the other ends of the probes are installed on the needle holes in one to one correspondence.

Furthermore, a plurality of springs are arranged between the fixed block and the adapter plate, first mounting holes corresponding to the springs one to one are formed in the fixed block, second mounting holes corresponding to the springs one to one are formed in the adapter plate, one ends of the springs are mounted on the first mounting holes, and the other ends of the springs are mounted on the second mounting holes.

Further, the adapter plate is a flexible circuit board.

The utility model has the advantages that:

through a plurality of the setting of probe makes on the connector the needle point contacts with the product, is surveyed the data of product via the probe transmission, and finally passes through the keysets transmits the outer antithetical couplet computer to accomplish the test of product, its simple structure, test effect are good, a plurality of the probe is the mode of double block and column type evenly arranging, increased the test point on the product with the probe connection the contact probability of needle point has reduced the condition with the contact failure of product, thereby reaches the purpose that reduces the misdetection rate.

In addition, in the process that the needle point is in contact with the product, the spring is arranged, so that the contact process is elastic contact, the needle point has certain self-adjusting capacity, and the product is prevented from being damaged due to rigid contact with the product.
