Embodiment 1

[0060] Such as Figure 8 Shown, a kind of OBD connector protective cover application method, this protection method comprises the following steps:

[0061] S1: Disconnect the OBD connector to control the circuit breaker: Insert the connecting terminal part of the OBD connector into the housing, and the connecting terminal part and the locking assembly are snapped and locked; the first expansion plate and the second expansion plate are tight due to the elastic effect Fit the connecting terminal part, then put the sealing frame on the outside of the OBD connector, and screw on the nut to complete the sealing of the protective cover; at this time, the indicator light is off;

[0062] S2: OBD connector is powered on: the locking component locks the connection terminal, and the protective cover cannot be separated from the OBD connector; at this time, the indicator light is on;

[0063] S3: The protective cover is opened correctly: the key is inserted into the lock cylinder, the k...

Embodiment 2

[0079] A method for applying an OBD connector protective cover, comprising the following steps:

[0080] S1: Disconnect the OBD connector to control the circuit breaker: At this time, the indicator light 3 is off, insert the connecting terminal part 18 of the OBD connector 17 into the housing 1, and the connecting terminal part 18 and the locking assembly 8 are snapped and locked. The first telescopic plate 21 and the second telescopic plate 22 are tightly attached to the connection terminal part 18 due to the elastic effect, and then the sealing frame 28 is set on the outside of the OBD connector 17, and the nut 31 is screwed on to complete the sealing of the protective cover;

[0081] S2: The OBD connector is powered on: the indicator light 3 is on, the locking component 8 locks the connection terminal part 18, and the protective cover cannot be separated from the OBD connector 17;

[0082] S3: The protective cover is opened correctly: the key is inserted into the lock cylin...

Abstract

A method for apply an OBD connector protective cover includes the following steps: S1: Disconnect the OBD connector control circuit breaker, inserting the connecting terminal part of the OBD connectorinto the housing, clamping and locking the connecting terminal part with the locking assembly, tightly fitting the first expansion plate and the second expansion plate with the connecting terminal part due to the elastic action, and then sleeving the sealing frame on the outside of the OBD connector to complete the sealing of the protective cover; S2: The OBD connector is energized; S3: Open theshield; S4: When the shield is illegally unlocked, the locking assembly is still locked, at which time the sensor works and the alarm emits a continuous buzzing alarm. The invention improves the sealing, dustproof and waterproof performance of the protective cover of the OBD connector, prevents the protective cover from aging too fast, prolongs the service life, ensures the sustainable normal operation of the OBD connector, and improves the impact resistance of the protective cover of the OBD connector.

Description

technical field [0001] The invention belongs to the technical field of vehicle OBD connector protection, and in particular relates to an application method of an OBD connector protective cover. Background technique [0002] With the development of industrialization, we have entered the automobile society. With a large number of vehicles, various failures inevitably occur in daily driving. In order to monitor the running status of the engine and the working status of the exhaust gas after-treatment system at any time, once a situation that may cause excessive emissions is found, a warning will be issued immediately, and OBD (On-board diagnostics, on-board diagnostic system) came into being. [0003] When the on-board diagnostic system is working, in order to facilitate the connection, the OBD connector is often used in the prior art. In order to protect the OBD connector, a protective cover for the OBD connector is often used in the prior art. [0004] For example, the pat...
