Description

Technical Field

[0001] This utility model relates to the field of electronic control valves for automotive variable displacement compressors, specifically a dedicated lead wire for an electronic control valve for an automotive variable displacement compressor. Background Technology

[0002] In automotive air conditioning systems, the electronically controlled valve of the variable displacement compressor is a key component for precise adjustment of cooling capacity, and its performance directly affects the energy efficiency and comfort of the air conditioning system. The electronically controlled valve is typically connected to the vehicle control system via a wiring harness to receive control signals and achieve on / off or proportional adjustment. Currently, traditional automotive variable displacement compressor electronically controlled valves generally use a single-lead plus grounding wire wiring harness connection method, with a single-pin interface structure, meaning that the circuit connection is completed through a single signal pin in conjunction with the machine body ground or an independent grounding wire.

[0003] However, with the diversification of automotive electronic architectures, some vehicle models or control systems require dual-wiring harness (dual-pin) power supply and signal transmission methods to improve control stability or meet specific communication protocol requirements. In this case, when using traditional single-pin electronically controlled valves, OEMs or repair shops must add an extra power or signal line to the existing wiring harness, along with corresponding connectors, to achieve a dual-wire connection. This modification not only increases the complexity of the wiring harness system and material costs but also leads to cumbersome installation processes, increased risk of wiring errors, and difficulties in management and vehicle compatibility during production assembly and after-sales maintenance due to the need to maintain multiple wiring harness configurations.

[0004] In addition, existing wiring harness structures are mostly fixed designs, lacking flexibility and unable to meet the different application requirements of single and dual wiring harnesses on the same interface platform. This results in poor product versatility and makes it difficult to meet the trend of multi-model platform development. To address this, a special lead wire for the electronic control valve of a variable displacement compressor in automobiles is proposed. Utility Model Content

Connector 2 is provided with connector 3, which is connected to wire harness 3. The end of wire harness 3 away from connector 3 is provided with a terminal. Connector four is connected to the end of wire harness two, and connector four is connected to connector five through wire harness four.

[0007] As a further embodiment of this utility model: the outer peripheral surfaces of wire harness one and wire harness two are provided with wire harness sleeves.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-5 In this embodiment of the present invention, a dedicated lead wire for an electronically controlled valve of a variable displacement automotive compressor includes: Connector 1, which has wire harness 2 and wire harness 3 installed on it; Connector 2 4 is connected to the end of the wire harness 1 2. Connector 2 4 is provided with connector 3 5, which is connected to wire harness 3 6. The end of wire harness 3 6 away from connector 3 5 is provided with terminal 7. Connector 4 8 is connected to the end of wire harness 2 3, and connector 4 8 is connected to connector 5 10 via wire harness 4 9.

[0014] Specifically, the two ends of wire harness 2 are connected to connector 1 and connector 4 respectively. Connector 1 is always connected to the electronic control valve. The model of connector 1 is not limited and can be matched with different electronic control valves. The two ends of wire harness 3 are connected to connector 1 and connector 4 respectively. Connector 4 8 is always connected to the vehicle's plug-in connection cable. The model of connector 4 8 is not limited and can be adapted to meet the needs of the vehicle, but its overall function is consistent with it. The outer circumference of wire harness 2 and wire harness 3 is provided with wire harness sleeve 11. The wire harness sleeve 11 is made of rubber material and can connect wire harness 2 and wire harness 3. The second and third wire harnesses are centrally wrapped and effectively protected to prevent damage to their surfaces. The second connector, 4, is a female connector that can be connected to the third connector, 5, and the fifth connector, 10, which are male connectors. Both connectors can be inserted into the second connector, 4. The connector design ensures connection stability and conductivity while also facilitating insertion and removal. When a single wire with a single pin is used, the third connector, 5, is inserted into the second connector, and the function is the same as that of a single-pin wire. When a dual-wire, dual-pin connection is required, the third connector, 5, can be removed and left idle. Instead, one end of the fifth connector, 10, can be inserted into the second connector, 4, to form a dual-pin, dual-wire harness.

[0015] The above solution allows for flexible switching between single-wire single-pin and dual-wire dual-pin modes according to different needs, without the need for additional complex wiring harnesses and connectors.

[0016] The working principle and usage process of this utility model are as follows: When the car OEM is assembling the whole vehicle, if only the single-pin single-wire function is required, the worker does not need to operate it. The factory default is the single-pin single-wire mode. At this time, the function of the wire harness is equivalent to the traditional single-pin lead wire. However, when the OEM or repair shop needs to connect dual wires, the repair personnel first unplug plug three 5 from connector two 4 to make it idle, and then accurately plug connector five 10 into connector two 4 to quickly complete the connection of dual-pin dual wire harness to meet the needs of repair or modification.

[0017] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0018] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
