I. How are some special properties of battery connectors? ① Temperature resistance now the high operating temperature of the articulator 200C (except for a small number of high-temperature special articulators), the low temperature of -65 ° C. Because the articulator operation, the current in the touch point of the heat generated, resulting in a temperature rise, and therefore - the general view that the operating temperature should be equal to the ambient temperature and the temperature of the joints and the sum of the temperature rise. In some standards, clear rules of the articulator in the additional operating current under the allowable high temperature rise. ② resistance to moisture moisture intrusion will affect the articulation h insulation function, and corrosion of metal parts. Stabilization of hot and humid test conditions for the relative humidity of 90% ~ 95% (according to product standards, up to 98%), temperature +40 +20 ° C, the experimental time according to the rules of the product, less than 96 hours. Alternating humidity and heat test is more demanding. ③ salt spray articulator in the environment containing moisture and salt work, metal structural components, touching parts of the exterior processing layer may occur galvanic corrosion, affecting the physical and electrical function of the articulator. In order to assess the ability of the electric articulator to withstand this environment, the rules of the salt spray test. It is the articulator hanging in the temperature-controlled experimental box, with the rules of the concentration of sodium chloride solution sprayed with compressed air, constituting a salt spray atmosphere, the exposure time by the product standard rules, less than 48 hours. ④ oscillation and shock resistance oscillation and shock is an important function of the electrical connector, in special applications such as aviation and aerospace, railroads and road transport is particularly important, it is an important goal to test the consolidation of the mechanical structure of the electrical connector and the reliability of electrical touch. There are clear rules in the relevant experimental methods. Impact test should rule the peak acceleration, duration and impact pulse waveform, as well as the time of electrical continuity interruption. ⑤ other environmental functions according to the application requirements, the other environmental functions of the electrical connector sealing (air leakage, liquid pressure), liquid impregnation (on the specific liquid resistance to maltreatment of the ability to), low pressure and so on.
