In this paper, helical wave wire have been proposed as the vehicle connector for the wireless access in vehicular environments(5.925GHz) communication. This helical slow wave connector is design by considering the properties of critical parameter like helical mean radius, helical pitch, helical wire radius and distance of helical wire to shield. The design simulation and results can be used to determine the most suitable helical wave wire dimensions for vehicle communication connector. The optimized WAVE connector inserted the helical wave wire has insertion loss less than -0.76dB at 5.925GHz. It provides 31% of insertion loss with good performance. Therefore, the simulated results can be effectively used for optimum design of high frequency connector for vehicle communication.

In this paper, a quality inspection system was developed to identify the defective assembly of connectors used in automobile wiring. For waterproof connectors, an internal seal must be inserted for waterproofing. However, there are cases where it is omitted or double-inserted during production. An automatic inspection jig was designed using photosensors and touch switches to classify good and bad connector components. In the case of the existing visual inspection, 6,400 connectors were inspected when 5 people inspected for 8 hours. However, when using the inspection jig developed under the same conditions, 20,000 pieces were inspected. In other words, the productivity is greatly improved compared to the conventional visual inspection.

Driver for safety always check the status of their vehicle, and it is essential to understand. When driver know vehicle driving status, there is know vehicle driving status to use vehicle realtime control data by OBD-II of vehicle network and connected OBD-II connector. But, connector to receive OBD-II data differ each communication connection method to connect smart device.(such as smartphone, blackbox, EDR) if vehicle driver change another smart device from smart device(such as android -> iphone, iphone -> android), vehicle driver exist the inconvenience that purchase new OBD-II connector. in this paper, As make up for the fault, there is to implement one OBD-II connector that integrate Bluetooth, Wifi, WCDMA module. as result, anything smart device was notified realtime vehicle control data through implemented one OBD-II connector in this paper

The automotive environment is particularly demanding on connector performance, and is characterized by large temperature changes, high humidity and corrosive atmospheres. Fretting is a contact damage process that occurs between two contact surfaces. Fretting corrosion refers to corrosion damage at the asperities of contact surfaces. This damage is induced under load and in the presence of repeated relative surface motion, as induced for example by vibration. This paper critically reviews the works published previously on fretting corrosion of electrical connectors. Various experimental approaches such as testing machines, material selection, testing environments, acceleration testing techniques and preventing methods are addressed. Future research prospects arc suggested.

Recently, devices such as smartphone and vehicle blackbox and EDR(Evern Data Recorder knowed automotive real-time control and driving data to use OBD-2(in-vehicle network). when devices receive vehicle driving data, communication way use each Wifi, Bluetooth. but if user and driver change device to use OBD-2 connect, the device differ communication network way. and driver buy and change OBD-2 connect. In this paper, to remedy one's shortcomings, there integrate Bluetooth and Wifi network module and design integrability hardware as any another device know vehicle real-time control and driving data with one integrability connect.

In this paper, smoothing plane connector have been proposed as the vehicle connector for the wireless access in vehicular environments (5.925GHz) communication. This smoothing plane connector is designed by considering the properties of critical parameter like smoothing distance of start to end point of contact area. The design simulation and results can be used to determine the most suitable smoothing plane wire dimensions for vehicle communication connector. The optimized WAVE connector inserted the smoothing plane wire has insertion loss less than-0.17dB at 5.925GHz. It provides 20% of insertion loss with good performance. Therefore, the simulated results can be effectively used for optimum design of high frequency connector for vehicle communication.

Automobile door latch is a fine design and assembly techniques are required in order to produce them in a small component assembly shape such as a spring, injection products, a small-sized motor. The door latch is fixed to not open the door of the car plays an important role it has a direct impact on the driver's safety. In this study, during trimming of the terminals of the connector main components of the car door latch, reduce rollover and conducted a research to find a suitable effective shear surface. Using the Taguchi method with orthogonal array of Finite Element Analysis and optimal Design of Experiments were set up parameters for the shear surface quality of the car door latch connector terminals. The design parameters used in the analysis is the clearance, the radius, and the blank holding force, the material of the connector terminal is a C2600. Trimming process optimum conditions suggested by the analysis has been verified by experiments, the shear surface shape and dimensions of a final product in good agreement with forming analysis results.Taguchi method from the above results in the optimization for the final rollover and effective shear surface improved for a vehicle door latch to the connector terminal can be seen that the applicable and useful for a variety of metal forming processes other than the trimming process is determined to be applicable.

최근 스마트폰, 블랙박스, EDR등에서 자동차 네트워크인 OBD-II를 이용하여 자동차 실시간 제어데이터를 알 수 있게 되었다. 하지만 각각의 장치(스마트폰, 블랙박스, EDR등)에서는 OBD-II에서 자동차 데이터를 수신 받을 때 사용되는 통신 네트워크가 다르다. 본 논문은 이러한 단점을 보완 하고자 각 장치에서 대부분 사용되어 지는 Bluetooth와 Wifi, WCDMA 모듈을 통합하여 사용자가 1개의 리더기 만으로도 어느 장치에서든지 OBD-II네트워크에서 자동차 실시간 제어 데이터를 알 수 있는 OBD-II 네트워크의 리더를 위한 통합 하드웨어를 구현 하였다.
