LV214 standard micro friction testing machine

The European automotive connector standard isLV214The automotive connector standard in the United States isUSCAR2These two standards have become dominant in the connector industry. Firstly, each product must achieve two objectives*The important criteria areUL(United States) andVDE(Germany)/European certification.ULandVDE (Association of Electrical Engineering)Organizations certify electronic products used in automobiles and other applications through strict testing protocols. These certifications prove that the product meets a strict set of requirements**Guidelines for sexuality, reliability, and environmental sustainability. They also have to comply with two car standards, the United States'USCARand EuropeanLV214.

LV214It is an automotive standard developed by representatives of German car manufacturers Audi AG, BMW AG, Daimler AG, Porsche AG, and Volkswagen AG. For almost all**toXFor tier suppliers, they are all*ofLV214The standard is still in draft form technically, but includesLumbergTheJAETheSchleunigerTheTE ConnectivityThe connector companies within have already provided products that meet the objectives of this standard.

LV214Main parameters and testing equipment of the standard

At present, the micro friction testing equipment required by automotive terminal customers in the market is mainly based onLV214Standard. Our company has developed this device andpushHaving been on the market for many years, the model isLW-1220MCMicro motion friction testing machine. Below isLV214standardMicro Friction Testing MachineMain parameters,If you need specific testing machine parameters, you can ask us for them!

LV214The main parameters for standard micro motion friction are:

Test sample:3 of them

Impedance acquisition frequency:4Hz

Micro motion distance:50 microns

Friction frequency:1HZ

Number of cycles:100000 times

Electrical compliance: not greater than100mv, 10mA (Important)

Of course, this standard involves other testing items, which are not included in this equipment. The testing parameters of this micro friction testing machine are limited to the above indicators. Of course, it can also be customized according to customer requirements, such as adding current control, adding workstations, etc.

With the continuous improvement of automotive performance, automotive connectors, as an important component of automobiles, have also been put forward with higher requirements. Before using a car connector, the host factory verifies the quality of the connector through corresponding testing standards. So what are the requirements of major automakers for testing specifications of automotive connectors and wiring harnesses?

VW-75174-(LV214-2010)-EN-Test Specification for Automotive Connectors

Simulate the visible pressure on a crimping connector during its typical lifecycle, and ensure that the crimping mechanical function is strong enough and the current is stable. The development of this specification is mainly used for automatic copper wires one by one. Only other structures or core materials specifically mentioned somewhere are applicable. This specification does not apply to wires that have not been mentioned before.

LV214-2010Defects in the mold, electroplating quality, wire and cable distribution for testing the crimping geometry. Besides having someone likeLV214-2010Confirm a connector system to ensure that the entire product crimping height range is acceptable, otherwise it must be executedLV214-2010Testing a connector system specification also requires confirmation of those that have not been testedLV214-2010Tested, like high-temperature exposure. The program included in the standard is intended to include performance testing and the development of electric terminal crimping, which is only applicable to electric connectors at low voltage（0-48VDC）Electronic connectivity system for road vehicle applicationsMAXThe high temperature is125The next component. ifOEMIf the customer approves these procedures for voltages and temperatures exceeding this limit, higher voltage and temperature testing will be necessary.
