Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a long-range OBD diagnostic device of vehicle, be in including diagnostic device body 1 and setting protection casing 2 on the diagnostic device body 1, protection casing 2 is one end open-ended casing column structure, just protection casing 2 passes through connecting piece detachable covers such as bolt and establishes 4 one sides of terminal panel at diagnostic device body 1, and binding face department is provided with the sealing washer, constitute between protection casing 2 and the terminal panel 4 and hold chamber 6, lead to the line hole 5 has been seted up on the casing of protection casing 2, lead to the line hole 5 and supply communication wiring 3 to penetrate to holding the intracavity. Carry out dustproof and waterproof's protection through the protection casing to binding post 20's on the terminal panel 4 junction, avoid its terminal structure to receive the erosion of dust and water stain and cause contact failure or short circuit, guarantee its job stabilization nature.

As shown in fig. 3 to 5, a clamping assembly is arranged on the wall body of the protective cover 2 corresponding to the accommodating cavity 6, the clamping assembly is arranged corresponding to the through hole 5, and the clamping assembly clamps the communication connection wire 3 penetrating into the through hole 5. Because the vehicle produces higher frequency's vibrations in the course of the work, the junction of binding post 20 also receives vibrations easily and not hard up, causes contact failure, carries out the centre gripping to the pencil through centre gripping subassembly, can effectual assurance binding post's stability.
