Problems solved by technology

[0003] When snap-fit ​​connectors are used in lamps, they will be affected by high temperature, low temperature or hot and humid environment, their own plastic characteristics and the molding of the shell. Over time, aging may lead to cracking and breaking, making the whole The snap-fit ​​connector cannot be used or partially fails
The phenomenon of cracking of snap-in connectors cannot occur in a short period of time, but only occurs when time and environmental changes accumulate to a certain extent. The existing detection methods for the reliability of snap-in connectors are not comprehensive, Inconsistent and differentiated, the reliability of snap-fit ​​connectors cannot be guaranteed

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0028] see figure 1 , a method for testing the reliability of snap-fit ​​connectors provided in an embodiment of the present invention. The method includes the following steps:

[0029] Step 101: Provide a buckle-type connector, and the material of the buckle-type connector is plastic. The number of snap-fit ​​connectors is determined according to actual conditions. In this embodiment, the number of snap-fit ​​connectors is 20. Certainly, in other implementations, the number of snap-fit ​​connectors may also be 10, 30 or more.

[0030] Step 103: Check the snap-fit ​​connector. When there are no peaks, cracks, or whitening under stress and fatigue at the edges and corners of the snap-fit ​​connector, the snap-fit ​​connector The material is acceptable. This step is mainly...

Abstract

The invention provides a buckle type connecting piece reliability test method, comprising the steps of: providing buckle type connecting pieces prepared by materials; detecting whether the materials of the buckle type connecting pieces are qualified; dismounting the buckle type connecting pieces on a piece to be mounted to obtain assembling performance of the buckle type connecting pieces; assembling the buckle type connecting pieces on the piece to be mounted and then performing waterproofness test to obtain waterproofness of the buckle type connecting pieces; performing falling test to obtain sudden impact resistance of the buckle type connecting pieces; performing alternate hot and humid test to detect whether the environmental resistance design of the buckle type connecting pieces is defective; and evaluating reliability of the buckle type connecting pieces. The test method tests the buckle type connecting pieces in fives aspects including materials, assembling performance, waterproofness, sudden impact resistance and environmental resistance design, and effectively simulates design defects of the buckle type connecting pieces after a long-term of use.

Description

technical field [0001] The invention relates to a testing method, in particular to a testing method for the reliability of snap-in connectors. Background technique [0002] The snap-fit ​​connection connects two or more components together by snap-fitting to achieve a better sealing effect and enhance the strength of the entire body. Snap-in connectors are widely used in many fields such as household appliances, instruments, construction equipment, automobile industry and daily hardware. In the lighting industry, snap-fit ​​connectors are mainly used to make lamp shell components, providing simple and reliable connection structures, better sealing effects and high-strength shell components for lamps. [0003] When snap-fit ​​connectors are used in lamps, they will be affected by high temperature, low temperature or hot and humid environment, their own plastic characteristics and the molding of the shell. Over time, aging may lead to cracking and breaking, making the whole ...
