Salt-fog resistance of the connector when working in an environment containing moisture and salt, its metal structure, surface-treatent coating has the potential to produce electro-chemical corrosion of contacts, influence the physical and electrical properties of the connector. In order to assess the capacity of electrical connectors withstand such an environment provides salt spray test.

 

Air connectors, the very beginning in terms of quality assurances, are generally not easily damaged, once the loss, repair must be timely, wires and connectors circuit breaker is a frequent occurrence. Wires and connectors circuit breaker failure may be due to breaking of wire used, connectors, poor contact, connector Terminal loose making. As the wire break in the middle of the fault is very rare, mostly in the connector is disconnected, and therefore inspections should focus on carefully check the sensor and connect along wires, loose and poor contact. Fault caused by poor contact between connector circuit breaker is often due to the connector ends to a corrosive, dirt from outside entered the terminal or connection Sockets, resulting in a lower contact pressure. At this point, just detach the connector, replace the plug, and to change its connection status into normal contact.

 

Localization service strategy, combination of extensive regions of the professional pathway and talents, to more localized services to meet the customer's production, Dingyang localization projects to provide quality and affordable terminal block. "From the terms of use, as long as the RCA plugs, coaxial transmission signal wires are used to transmit composite video signals, but specially designed impedance of 75 ω wire can restore a better image, especially in long distance transmission difference more obvious. This is due to the special design of the wire impedance mismatch can be reduced and the effects of signal reflection to images to reduce ghosting.

 

Composite video connector most commonly used, but it is also a video transmission modes fidelity low, so asking when I restore the quality of the image and color difference video s-video terminal blocks are more appropriate. Transportation environmental factors related to the terminal block as the transport, loading and unloading of vehicles and other mechanical devices, pavement tool vibrations generated during operation process and issues arising from the collision. The simple test methods are: Visual (see appearance), weigh the weight (it has to cut corners), fire (flame retardant); try torsion. In order to meet the resistance of high temperature, low temperature, flame retardant, ensure stable and reliable part geometry. Terminal insulators used thermosetting plastic molded into shape. Interface sealing, line style using silicone rubber molded into shape.

 

Contact – plug-pin hole is contact organizations, divided into welding, crimping and around, used to implement circuit connections. Plug pin hole is the key terminal block components, which directly affects the reliability of the terminal block. Plug pin hole mostly using conductive good performance of flexible copper alloys machining, surface silver gilt achieve the objective of small contact resistance and corrosion. Must possess excellent electrical properties of the insulation, mechanical and process performance. Especially with the high density, the widespread use of miniaturized terminal blocks, effectively getting thinner wall thickness of the insulation.
