Description

Mounting fixture and test equipment

Technical Field

The utility model relates to the technical field of power distribution product testing, in particular to a mounting clamp and testing equipment.

Background

In the accessory surge series of the contactor, two pins of the product are two retraction springs, and after the surge is inserted into the contactor product, the pin tips of the two retraction springs can reliably contact the two ends of the coil of the contactor so as to form a parallel loop with the coil of the contactor, thereby realizing the function of inhibiting the surge. The testing of the resilience of this pin is a critical aspect of verifying that the product is reliable.

The retraction springs of these two pins have a process of being compressed and then stretched back during insertion into our contactor product, so that they must be ensured of sufficient resilience. The force is not only a single vector (including compressed force and rebound force), so that a clamp capable of reliably fixing a product and adjusting the angle of the product in multiple directions is required for testing, and the clamp has the characteristics of repeated operation, simplicity and easiness, and convenience, and is suitable for a large number of factory tests.

However, since the conventional test equipment is designed for a contactor, a bench vice is used to directly fix a product and then test the product when performing a mechanical test related to surge. The mounting fixture in the test equipment is not particularly sufficient for the firmness of product fixation (the test can be influenced by shaking in the test), and meanwhile, the test direction is only horizontal, so that the test of a plurality of test angles of the surge pin is difficult to meet.

Therefore, how to provide a mounting fixture and a testing device, so as to solve the technical problem that the testing direction of the existing testing device is only horizontal, and the testing of a plurality of testing angles of pins is difficult to meet.
