A speed sensor fixing bracket and its installation structure

Abstract

The invention discloses a rotating speed sensor fixing support and an installing structure thereof. A fixing plate, a first transition plate, a second transition plate, an installing plate used for installing an engine cable harness buckle and a U-shaped fixing groove used for fixing a sensor plug are included, the fixing plate and the second transition plate are vertically arranged in parallel, the first transition plate is arranged in a downwards-inclined manner, the fixing plate is fixed to one end of the first transition plate and is upwards, and the second transition plate is fixed to theother end of the first transition plate and is downwards; the installing plate is fixed to the higher side edge of the first transition plate, the installing plate is horizontally arranged, the installing plate is provided with an installing hole used for fixing the engine cable harness buckle, and no interference exists between the extending direction of the installing plate and the fixing plate; and the fixing groove is fixed to the bottom of the second transition plate, and the opening direction of the fixing groove faces the bottom of the first transition plate. By means of the rotating speed sensor fixing support, the rotating speed sensor plug can be easily and conveniently fixed, cable harness guide can be carried out, operation is convenient, an dthe

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to a rotational speed sensor fixing bracket and an installation structure thereof. Background technique [0002] In the field of automotive engine technology, generally the plug of the speed sensor is connected to the plug of the engine harness and suspended in the air, or the sensor plug is designed to be buckled and fixed to the bracket. In these forms, the connection between the sensor and the wiring harness has a high degree of freedom and poor vibration resistance. It is easy to loosen, and in severe cases, there is a risk of the engine losing the speed signal; and the buckle on the sensor plug can be disassembled repeatedly, which increases the cost of later maintenance and overhaul. On the other hand, in order to meet the safety and disaster prevention requirements of the engine room, a separate design is usually adopted. At least two brackets are used ...

Problems solved by technology

[0002] In the field of automotive engine technology, generally the plug of the speed sensor is connected to the plug of the engine harness and suspended in the air, or the sensor plug is designed to be buckled and fixed to the bracket. In these forms, the connection between the sensor and the wiring harness has a high degree of freedom and poor vibration resistance. It is easy to loosen, and in severe cases, there is a risk of the engine losing the speed signal; and the buckle on the sensor plug can be disassembled repeatedly, which increases the cost of later maintenance and overhaul

On the other hand, in order to meet the safety and disaster prevention requirements of the engine room, a separate design is usually adopted. At least two brackets are used at the crossing position of the speed sensor and the engine harness, which are respectively used for guiding and positioning the engine harness and fixing the plug of the speed sensor. This design bracket Large number of parts, high cost, tight assembly space, and difficult operation

The traditional design method results in waste of design cost and maintenance cost, poor assembly manufacturability and reliability, and even the risk of engine failure
