Description

Technical Field

[0001] The utility model relates to an oil quantity sensor, in particular to an oil quantity sensor with a DC plug, which is applicable to various systems requiring oil quantity detection. Background Art

[0002] The oil level sensor is mainly used as a detection part to detect the amount of oil in the oil tank. When installing the oil level sensor, the two signal harnesses of the oil level sensor are directly butt-welded to the detection circuit board of the valve body chamber. The welded oil level sensor works as a part of the valve body assembly. In order to prevent the oil from entering the valve body chamber and affecting the circuit board unit, the valve body chamber needs to be effectively sealed and isolated from the external oil.

[0003] The traditional way to solve the oil isolation of the valve body cavity is to inject sealant into the wiring harness through hole in the valve body cavity. However, if there is a problem with the sensor after injection, the entire valve body assembly can only be replaced. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an oil level sensor with a DC plug, so as to change the current situation that the oil level sensor cannot be simply and quickly separated from the docking wiring harness after welding.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An oil level sensor with a DC plug comprises an oil level sensor, wherein the DC plug is connected to a wiring harness of the oil level sensor and is covered by an adapter, and the adapter is fixed to a pipe end of the oil level sensor; a DC socket is installed in a corresponding valve body assembly detection chamber, and the DC plug is plugged into the DC socket.

[0007] The adapter includes a left half joint body and a right half joint body. The opposite end faces of the left half joint body and the right half joint body are provided with mounting holes and mounting columns. When the left half joint body and the right half joint body are spliced ​​together, the mounting holes are plugged into the mounting columns.

[0008] The left half connector body and the right half connector body are both provided with limiting grooves, which match the outer ring on the DC plug and limit the outer ring.

[0009] The left half connector body and the right half connector body are provided with wiring harness covering cavities.

[0010] The utility model provides an oil level sensor with a DC plug, which has the following technical effects:

[0011] 1) By changing the traditional welding sealing relationship to a DC plug, the structure itself is very simple and reliable. By installing the DC plug on the oil level sensor, it can ensure that the electrical performance is not attenuated and maintain the advantage of a simple structure.

[0012] 2) The DC plug is separated from the DC socket, which is easy to disassemble and replace, effectively reducing the cost of use. When the oil level sensor is installed on the system and fails during use, you only need to unplug the oil level sensor with the DC plug and replace it with a new DC plug oil level sensor in time, effectively reducing the cost of use and maintenance.

[0024] like Figure 1-5 As shown, a fuel level sensor structure with a DC plug includes a DC plug 1, an adapter 2, a fuel level sensor 3 and a DC socket 4.

[0025] The DC plug 1 is divided into an inner and outer double-layer structure, similar to an earphone plug, and the DC plug 1 is welded to the wiring harness of the oil level sensor 3. In this way, the oil level signal is transmitted through the DC plug instead of the traditional wiring harness.

[0026] The adapter 2 includes a left half connector body 2.1 and a right half connector body 2.2. The left half connector body 2.1 and the right half connector body 2.2 have mounting holes 2.3 and mounting posts 2.4 on their opposite end faces. When the left half connector body 2.1 and the right half connector body 2.2 are spliced, the mounting holes 2.3 on the left half connector body 2.1 and the right half connector body 2.2 are plugged into the mounting posts 2.4, thereby realizing the splicing of the left half connector body 2.1 and the right half connector body 2.2. A limiting groove 2.5 is provided in the left half connector body 2.1 and the right half connector body 2.2. The limiting groove 2.5 matches the outer ring 1.1 on the DC plug 1, and the limiting groove 2.5 limits the outer ring 1.1. After the left half connector body 2.1 and the right half connector body 2.2 are spliced, a wiring harness sheathing cavity 2.6 is formed, and the wiring harness sheathing cavity 2.6 can sheath the wiring harness.

[0027] The DC socket 4 is installed in the valve body assembly detection chamber, and the inside of the valve body assembly detection chamber only needs to be sealed for the DC socket 4.

[0028] Working principle and process:

[0029] 1) After the DC plug 1 and the wiring harness of the oil level sensor 3 are welded, the left half connector body 2.1 and the right half connector body 2.2 are used to cover the welded DC plug 1 and the wiring harness of the oil level sensor 3, and the DC plug 1 with the adapter 2 is inserted into the tube of the oil level sensor 3. The adapter 2 and the oil level sensor 3 are interference fit. During production, the adapter 2 is pressed into the oil level sensor 3 by moving the tool downward.

[0030] 2) When in use, the oil level sensor 3 with the DC plug 1 can be put into use by simply inserting it into the DC socket 4. When the oil level sensor 3 needs to be replaced, the oil level sensor 3 can be directly unplugged.
