[0022] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0023] As attached Figure 1 To Attachment Figure 6 As shown:

[0024] Embodiment 1: The utility model provides a waterproof connector structure for an internal and external electronic control integrated machine of a vehicle-mounted electric air conditioner, including an electronic control integrated machine 1, which is fixedly mounted on a vehicle frame, and a functional wiring harness is connected to the electronic control integrated machine 1 through a connector assembly 2; the connector assembly 2 includes a fixed socket 201, a connecting plug 202, an operating sleeve 203 and a control panel 204, the fixed socket 201 is fixedly mounted on the side of the electronic control integrated machine 1, the connecting plug 202 is plugged into the outside of the fixed socket 201, and the connecting plug 202 is connected to one end of the functional wiring harness, and the other end of the functional wiring harness is connected to a driver (such as a fan, a sensor driver, etc.), the operating sleeve 203 is rotatably connected to the outside of the connecting plug 202, and the control panel 204 is plugged into the side of the operating sleeve 203.

[0025] In the disclosed embodiment, the connector assembly 2 also includes a sealing ring 205, and the sealing ring 205 is inserted into the outside of the plug of the connecting plug 202. When the connecting plug 202 is inserted into the outside of the fixed socket 201, the two sides of the sealing ring 205 will be squeezed by the fixed socket 201 and the connecting plug 202 respectively, so that the connecting part between the connecting plug 202 and the fixed socket 201 can be sealed and blocked by the sealing ring 205, which can effectively prevent water from entering.

[0026] In the embodiment of the present disclosure, a quick-tightening groove is provided on the outside of the fixed socket 201, and an action protrusion 2031 is provided on the inside of the operating sleeve 203. The action protrusion 2031 is plugged into the inside of the quick-tightening groove. The quick-tightening groove is composed of a guide groove 2011 arranged radially along the fixed socket 201 and a locking groove 2012 arranged spirally along the axis of the fixed socket 201, and one end of the locking groove 2012 is connected to one end of the guide groove 2011. In use, when the fixed socket 201 and the connecting plug 202 are connected, it is only necessary to insert the connecting plug 202 into the outside of the fixed socket 201 and rotate the operating sleeve 203 in a small range to achieve the locking installation operation. When the connecting plug 202 is inserted into the fixed socket 201 in the front and middle stages, the action protrusion 2031 will enter the inside of the guide groove 2011 and move following the insertion action of the connecting plug 202. When the connecting plug 202 is inserted to the later stage, the action protrusion 2031 will enter the inside of the locking groove 2012, so that when the operating sleeve 203 is rotated, the action protrusion 2031 can drive the connecting plug 202 to continue to move toward the fixed socket 201 through the locking groove 2012 and squeeze the sealing ring 205, thereby achieving the purpose of waterproofing. In addition, this operation abandons the traditional threaded connection method, greatly reduces the number of rotations, and facilitates the installation and disassembly operation.

[0027] In the embodiment of the present disclosure, a control top spring 2041 is provided on the side of the control disk 204, and the two ends of the control top spring 2041 are respectively against the side of the control disk 204 and the inside of the operating sleeve 203, and the control disk 204 and the fixed socket 201 are opposite to each other. The side is provided with a one-way toothed ring 2042, and under the action of the control top spring 2041, the two groups of one-way toothed rings 2042 are plugged into each other, and the cross-sectional shape of a single gear tooth of the one-way toothed ring 2042 is a right triangle, and when the operating sleeve 203 rotates toward the direction close to the guide groove 2011, the two groups of The straight edges of the gear teeth of the one-way gear ring 2042 are engaged with each other. In use, after the fixed socket 201 and the connecting plug 202 are connected, the operating sleeve 203 will be automatically locked, so that the fixed socket 201 can always maintain the connection state with the connecting plug 202 to achieve stable transmission of information data. After the fixed socket 201 and the connecting plug 202 are connected, the control disk 204 and the one-way gear ring 2042 of the fixed socket 201 will be plugged into each other under the action of the control top spring 2041, so that the operating sleeve 203 will be locked thereafter. Under the clamping limit action of the straight edges of the gear teeth of the two sets of one-way gear rings 2042, it is always impossible to reverse (the rotation direction of the operating sleeve 203 toward the guide groove 2011 is considered as reverse rotation), thereby preventing the action protrusion 2031 from entering the guide groove 2011, causing the connection between the fixed socket 201 and the connecting plug 202 to fail, thereby preventing the effective connection from loosening and causing communication failure. In addition, when the operating sleeve 203 rotates forward, the two sets of one-way gear rings 2042 can avoid each other and press against each other under the extrusion of the bevel edges of the gear teeth. The compression controls the top spring 2041, so as not to hinder the operation of the operating sleeve 203 to rotate forward to lock the fixed socket 201 and the connecting plug 202, and the use is stable. When the connecting plug 202 needs to be removed normally, it is only necessary to pull the control disk 204 to release the plug-in relationship between the two sets of one-way gear rings 2042, and the operating sleeve 203 can be reversed normally to allow the action protrusion 2031 to enter the inside of the guide groove 2011 from the locking groove 2012, thereby realizing the subsequent operation of pulling out the connecting plug 202 from the inside of the fixed socket 201, which is convenient and flexible to use.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In the present invention, when the fixed socket 201 and the connecting plug 202 need to be connected, the connecting plug 202 only needs to be inserted into the outside of the fixed socket 201 and the operating sleeve 203 can be rotated in a small range to achieve the locking installation operation. When the connecting plug 202 is inserted into the front and middle stages of the outside of the fixed socket 201, the action protrusion 2031 will enter the inside of the guide groove 2011 and move along with the insertion action of the connecting plug 202. When the connecting plug 202 is inserted into the later stage, the action protrusion 2031 will enter the inside of the locking groove 2012, so that when the rotation is performed, the locking groove 2012 can be locked. When operating the sleeve 203, the action protrusion 2031 can drive the connecting plug 202 to continue to move toward the fixed socket 201 through the locking groove 2012 and squeeze the sealing ring 205, so as to achieve the purpose of waterproofing. After the fixed socket 201 and the connecting plug 202 are connected, the sleeve 203 can be operated to automatically lock, so that the fixed socket 201 can always maintain the connection state with the connecting plug 202 to achieve stable transmission of information data. After the fixed socket 201 and the connecting plug 202 are connected, the control panel 204 and the fixed socket 201 are controlled by the control top spring 2041. The one-way toothed rings 2042 of the socket 201 will be plugged into each other, so that the operating sleeve 203 will never be able to reverse under the clamping and limiting action of the straight edges of the gear teeth of the two sets of one-way toothed rings 2042 (the rotation direction of the operating sleeve 203 toward the guide groove 2011 is considered as reverse rotation), thereby preventing the action protrusion 2031 from entering the guide groove 2011 and causing the connection between the fixed socket 201 and the connecting plug 202 to fail, thereby effectively loosening the connection and causing communication failure. In addition, when the operating sleeve 203 rotates forward, the two sets of one-way toothed rings 2042 will be locked. 42 can avoid each other and compress the control top spring 2041 under the squeezing action of the bevel of the gear teeth, so as not to hinder the operation of the operating sleeve 203 to rotate forward to lock the fixed socket 201 and the connecting plug 202. If it is necessary to remove the connecting plug 202 normally during subsequent maintenance, it is only necessary to pull the control disk 204 to release the plug-in relationship between the two sets of one-way gear rings 2042, and the operating sleeve 203 can be reversed normally to allow the action protrusion 2031 to enter the inside of the guide groove 2011 from the locking groove 2012, thereby realizing the subsequent operation of pulling out the connecting plug 202 from the inside of the fixed socket 201.

[0030] In another embodiment, a long strip-shaped adapter hole is provided on the side connecting plate of the electronic control integrated machine 1, so that bolts can pass through the adapter hole to connect and fix the electronic control integrated machine 1 to the vehicle frame.
