Dual-linkage module test jig

Abstract

The invention discloses a dual-linkage module test jig. According to the jig, one side of a box cover is hinged to the edge of a box body, a base is fixed into the box body, the lower end of a supportis fixed to the base, two vertical sliding rods are arranged at the two sides of the support respectively, the lower ends of the vertical sliding rods are fixed to the base, the upper ends of the vertical sliding rods are fixed to the upper end of the support, a sliding sleeve is arranged on each vertical sliding rod in a sleeving mode, a spring is arranged on each vertical sliding rod in a sleeving mode, a sliding platform is horizontally arranged and is fixedly connected with the sliding sleeves, a roller is rotationally arranged at the upper end of a roller support, the roller support is arranged on the sliding platform, a test socket is fixed to the lower side of the sliding platform, a fixed platform is horizontally arranged on the base and located under the sliding platform, and a test pin is fixed to the fixed platform and is matched with the test socket in position. According to the jig, when a shielding box is closed, a test structure is inserted and closed through the box cover at the same time, so that operation is easy, the actions of an operator can be reduced, and operation efficiency can be obviously improved.

Description

technical field [0001] The invention relates to a test fixture, in particular to a double linkage module test fixture. Background technique [0002] Some tests are more sensitive to external factors in the test environment. This test environment needs to refer to some shielding boxes of different specifications to reduce and reduce the interference factors of the environment. The advantage of the shielding box is that it can reduce the interference of the external environment, but when the test fixture is placed in the shielding box, it involves the tester to act on the shielding box and the fixture at the same time. This operation is difficult and has a significant impact on the production test efficiency. In addition, there are relatively high requirements for the proficiency and operating skills of testers in order to ensure the accuracy of the test, and manual operation cannot complete the two actions of closing the box and closing the test interface at the same time, th...

The advantage of the shielding box is that it can reduce the interference of the external environment, but when the test fixture is placed in the shielding box, it involves the tester to act on the shielding box and the fixture at the same time. This operation is difficult and has a significant impact on the production test efficiency. In addition, there are relatively high requirements for the proficiency and operating skills of testers in order to ensure the accuracy of the test, and manual operation cannot complete the two actions of closing the box and closing the test interface at the same time, there must be a sequence, which will inevitably affect the final test structure the accuracy of

With the pneumatic scheme, the test can be performed by closing the test interface through the pneumatic drive mechanism after closing the box, so as to ensure the sealing of the test, but the pneumatic structure needs to use high-cost components such as air source and cylinder, which increases the modification cost of the fixture
