An instrument assembly integrating wiring harness connectors

Abstract

The invention discloses an instrument assembly integrated with wire harness connectors, which includes an instrument housing in which electrical components are installed, wires are drawn from the electrical components, and wire harnesses are integrally formed on the instrument housing. The connector, the wires are arranged inside the instrument housing, and the wires are inserted into the wire harness connector inside the instrument housing. The invention has the advantages of simple structure, safe and reliable wire connection, good waterproof performance and convenient and quick assembly.

Description

technical field [0001] The invention relates to an instrument on a motorcycle, in particular to an instrument assembly integrated with a wiring harness connector. Background technique [0002] Instruments, as electrical components of motorcycles, are very important to ensure driving safety. see figure 1 The motorcycle meter includes a watch mirror 1', a lining board 2', a letter board 3' and a meter housing 1, and electric components such as an oil gauge 4 (displaying the oil quantity) and a light bulb 6 (lighting the meter) are installed in the meter; see figure 2 In the traditional technology, the wires 7' such as the oil gauge wire and the bulb wire are led to the outside of the instrument case 1, and then these wires are concentrated in the independently provided wire harness socket connector 4', and the plug on the car body is assembled. 5' is inserted into the wiring harness slot connector 4' to realize electrical connection, this structure has the following defect...

AI Technical Summary

Problems solved by technology

[0003] 1. Set up an independent wire harness slot connector 4’ outside the meter, which increases the cost of the meter

[0004] 2. The wire harness slot connector 4' is in a free state, that is, the wire harness slot connector 4' and the instrument are only connected together by wires, and the wire harness slot connector 4' is not fixed on the instrument, which makes the The position of the wire harness slot connector 4' is uncertain and movable during driving vibration, etc. Obviously, this will increase the uncertainty of the flexible wire arrangement, and in order to prevent the wire from being pulled, this will inevitably increase the length of the wire, so that The wire can meet various uncertain positions; in order to avoid the connection between the wire and the electrical components being pulled, it is necessary to set a limit rib 6' on the bottom wall of the meter case 1, which increases the structural complexity of the meter case 1

[0005] 3. The uncertainty of the position of the wire will cause the exposed wire to interfere with the surrounding parts and wear, and there is a certain potential safety hazard

[0006] 4. Due to the non-fixed position of the wire harness slot connector 4', when inserting the plug 5' on the car body into the wire harness slot connector 4', the assembler needs to hold the wire harness slot connector 4' with one hand, and the other Push plug 5' into harness socket connector 4' with one hand, increasing assembly difficulty and labor

[0007] 5. Since the electrical components such as the light bulb 6 and the oil gauge 4 are arranged inside the instrument case, and the wire harness slot connector 4' is set outside the meter case 1 as an independent component, the joint between the wire 7' and the wire harness slot connector 4' The place is completely exposed to the outside of the instrument, and it is easy to cause a short circuit problem of water ingress; and the wire 7' needs to pass through the bottom wall of the meter case 1 to be electrically connected to the electrical components, so it is easy to generate a short circuit at the position where the wire passes through the meter case 1. Sealing problem, which causes water to enter the inside of the meter, which has a great impact on the meter
