Description

Overvoltage preventing structure for testing B2B connector

Technical Field

The utility model relates to a test B2B connector prevent excessive pressure structure.

Background

The existing non-mapping test industry tests the B2B connector mainly uses the test pin module to press the B2B connector on the product to be tested, so that the test probe in the test pin module contacts the test point of B2B on the product to be tested, and then derives the signal on the product B2B to test. In a test method for automatically testing a plurality of B2B connectors, a test pin module is often used to test a plurality of B2B connectors on a product. The traditional test pin module is provided with two layers of springs, wherein the first layer of spring is used for floating, and the test pin module can be smoothly guided into a B2B connector to be tested during pressing; the second layer of springs is used for protecting the test probes, and when the inner groove of the test probe module is led into the B2B to be tested, the test probes are exposed and contacted to conduct the B2B to be tested, so that a signal test is conducted.

The traditional two-layer spring test needle module has the defects that the welding height difference of the B2B connector to be tested cannot be compatible, the test needle module is firstly led into the B2B under the floating action of the first layer of springs in the process of contact testing of the B2B connector, the second layer of springs are compressed to expose a signal of the B2B connector, and the limiting column acts on the carrier plate at the moment to limit the test needle module.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, test stability height and have the test B2B connector of protection product prevent excessive pressure structure.

The utility model adopts the technical proposal that: the utility model discloses a test module and locating the spring unit of test module bottom, spring unit include with excessive pressure spring unit, guide spring unit and the buffer spring unit that test module's bottom connected gradually, be equipped with on guide spring unit's the bottom with test module signal of telecommunication connection's probe, the one end of probe can be passed the buffer spring unit.

Further, the overvoltage spring assembly comprises a first mounting plate arranged on the test module, a second mounting plate arranged below the first mounting plate in an adaptive mode, and a plurality of first springs arranged between the first mounting plate and the second mounting plate.

Further, the guide spring assembly comprises a third mounting plate and a plurality of second springs, wherein the third mounting plate is arranged below the second mounting plate, and the second springs are arranged between the second mounting plate and the third mounting plate.

Furthermore, a flexible circuit board is arranged on the bottom of the third mounting plate, one end of the flexible circuit board is connected with the probe electric signal, and the other end of the flexible circuit board is connected with the test module electric signal.

Furthermore, the buffer spring assembly comprises a fourth mounting block arranged at the bottom of the third mounting block, a contact block arranged below the fourth mounting block, and a plurality of third springs arranged between the fourth mounting block and the contact block.

Furthermore, a first through hole and a convex block are arranged on the fourth mounting block, a plurality of needle holes which are matched with the probes and communicated with the first through hole are formed in the convex block, a second through hole which is communicated with the needle holes is formed in the contact block, one end of each probe sequentially penetrates through the first through hole and the corresponding needle hole, and the end of each probe extends into the corresponding second through hole.

The utility model has the advantages that: when the test module passes through in the leading-in product that awaits measuring of second spring, the third spring is compressed completely and is exposed behind the probe, will further to prevent excessive pressure first spring compresses, after compressing a certain amount, spacing post contact on the test module bears the carrier plate of product, utilizes the clearance of first spring compression to guarantee to await measuring under the condition that B2B connector actual height is inconsistent with theoretical height, the test can be stable and do not damage the connector, its simple structure, practicality are strong.
