Description

Multichannel test fixture

Technical Field

The utility model discloses be applied to test equipment's technical field, in particular to multichannel test fixture.

Background

Traditional test equipment is single channel or dual channel design usually, can not a plurality of product tests simultaneously during the test to can not test alone every passageway, the efficiency of software testing is low, and the limitation is big. Meanwhile, the connection is unstable, and the reliable connection of the product and the test module cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a connect reliable, multichannel test fixture that efficiency of software testing is high.

The utility model adopts the technical proposal that: the utility model discloses a test base and a plurality of clamping subassembly, the last correspondence of test base is equipped with a plurality of clamping subassembly one-to-one complex test connection subassembly, test connection subassembly includes connector, a pair of spacing fixture block and test module, the connector with test module electric connection, test module and outside host computer electrical signal connection, two spacing fixture block sets up respectively the both ends of connector, spacing fixture block with the spacing cooperation of clamping subassembly.

According to the scheme, the clamping assembly is used for clamping products. Through setting up a plurality ofly simultaneously test coupling assembling realizes testing a plurality of products simultaneously. The test module is used for testing the products to be tested, and the test connecting assembly is provided with the test module through each test connecting assembly, so that each channel is tested independently, and the tests among the products are not influenced mutually. The clamping assembly is clamped and fixed through the matching of the two limiting clamping blocks and the two ends of the clamping assembly, and the connection reliability is guaranteed. The connector is connected with a product to be tested, and testing is achieved. The test efficiency is effectively improved through a multi-channel independent test mode.

According to a preferred scheme, the clamping assembly comprises a support plate and a cover plate, the cover plate is hinged and matched on the support plate, the support plate and the cover plate are matched to clamp and fix a product to be tested, and the support plate is matched with the limiting clamping block.

It is thus clear that by above-mentioned scheme, through the support plate carries out preliminary spacing of the product that awaits measuring, the support plate with the apron complex will await measuring the effective reliable clamp of product and fix.

In a further preferred scheme, a spring pin is arranged on the limiting clamping block, and a limiting hole matched with the spring pin is arranged on the carrier plate.

According to the scheme, the spring pin is matched with the limiting hole, so that the clamping assembly for testing is clamped and limited, and the clamping assembly is prevented from being separated from the testing process.

In a further preferred scheme, the bottom of the carrier plate is provided with a guide pillar, and the test base is provided with a guide hole matched with the guide pillar.

According to the scheme, the guide pillar is arranged to ensure that a product to be tested on the clamping assembly can be accurately butted with the connector.

Further preferably, a handle is arranged on the carrier plate.

According to the scheme, the handle is arranged, so that the clamping assembly is convenient to carry and move.

One preferred scheme is, still be equipped with control panel on the test base, control panel is last to be equipped with correspondingly with a plurality of test connection subassembly corresponds a plurality of independent switches of electricity connection one-to-one.

According to the scheme, the independent switches are correspondingly arranged to control the test connection assemblies, so that each test channel is independently controlled, and the test efficiency is improved.

Detailed Description

As shown in fig. 1 to 3, in this embodiment, the utility model discloses a test base 1 and a plurality of clamping subassembly, the last correspondence of test base 1 is equipped with a plurality of clamping subassembly one-to-one complex test connection subassembly, test connection subassembly includes connector 2, a pair of spacing fixture block 3 and test module, connector 2 with test module electric connection, test module and outside host computer signal connection, two spacing fixture block 3 sets up respectively connector 2's both ends, spacing fixture block 3 with the spacing cooperation of clamping subassembly.

In this embodiment, the clamping assembly includes a support plate 4 and a cover plate 5, the cover plate 5 is hinged and matched on the support plate 4, the support plate 4 is matched with the cover plate 5 to clamp and fix a product to be tested, and the support plate 4 is matched with the limiting fixture block 3.

In this embodiment, the limiting fixture block 3 is provided with a spring pin 6, and the carrier plate 4 is provided with a limiting hole 7 matched with the spring pin 6. And the limiting fixture block 3 is provided with a limiting groove matched with the carrier plate 4. The spring pin 6 is fixed on the limiting fixture block 3, and the movable part of the spring pin 6 penetrates through the limiting groove.

In this embodiment, the bottom of the carrier 4 is provided with a guide post 8, and the test base 1 is provided with a guide hole 9 matching with the guide post 8.

In the present embodiment, the carrier plate 4 is provided with a handle 10.

In this embodiment, still be equipped with control panel 11 on the test base 1, control panel 11 is last to be equipped with correspondingly with a plurality of test connection subassembly corresponds a plurality of independent switches 12 of electricity connection one-to-one.

The utility model discloses a theory of operation:

an operator places a product to be tested in the carrier plate 4, the cover plate 5 is rotated to clamp the product to be tested, and finally the cover plate 5 and the carrier plate 4 are locked.

The spring pin 6 is pulled to retract, the clamping assembly clamping the product is inserted into the connector 2, and guiding is carried out through matching of the guide pillar 8 and the guide sleeve 9.

When the limiting hole 7 is coaxial with the spring pin 6, the spring pin 6 extends out under the action of the elastic force of the spring pin.
