Description

A wiring harness connection port and wiring harness assembly Technical Field

[0001] The present invention relates to the technical field of wire harness connection ports, and in particular to a wire harness connection port and a wire harness assembly. Background Art

[0002] The automotive wiring harness assembly is an important part of the automotive electrical system. It can realize the power supply and communication between various components of the car. It is the channel for transmitting information such as car driving instructions and safety protection signals. At present, the two ends of the wiring harness assembly connect and communicate with the car's power supply, on-board computer and car equipment (such as rearview mirrors, lights, cameras, audio, etc.) through wiring ports.

[0003] However, the wiring ports of the existing wiring harness assembly are locked by a simple buckle after connection. This usage method has the following disadvantages:

[0004] 1. It has no protection function. When the wiring harness is pulled by external force, it is easy to cause the buckle of the terminal to be damaged, broken, or the wiring harness to be disconnected. During subsequent use, the terminal loses the locking relationship of the buckle, and it is easy to have a false connection between the terminal and the port, affecting the normal use of the automotive equipment and having poor stability.

[0005] 2. There is no quick-release structure. After the terminal block is installed, if it needs to be disassembled, it is necessary to use tools (such as a screwdriver, etc.) to pry open the buckle to complete the disassembly of the terminal block. The steps are cumbersome, and it is easy to cause the buckle to break and be damaged when prying open the buckle, affecting the subsequent assembly and use. The flexibility and practicality are poor.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Please refer to Figures 1 to 10:

[0041] Embodiment 1: The present invention provides a wiring harness connection port and a wiring harness assembly, comprising a fixed module 1, the fixed module 1 comprising a fixed port 101 and a positioning block 102, the fixed port 101 being fixedly mounted on an automotive electronic device, and the positioning block 102 being plugged into the top of the fixed port 101; a plug-in module 2, the plug-in module 2 comprising a plug-in terminal 201 and a resisting block 202, the plug-in terminal 201 being plugged into the interior of the fixed port 101, and the resisting block 202 being plugged into the plug-in terminal 201 interior; functional component 3, functional component 3 includes a connecting seat 301, an adjusting seat 302, a positioning rod 303, a positioning block 304 and a spring swivel 305, the connecting seat 301 is plugged into the side of the plug-in terminal 201, and the adjusting seat 302 is rotatably connected to the outside of the connecting seat 301, the positioning rod 303 is rotatably connected to the inside of the connecting seat 301, and the positioning block 304 is plugged into the inside of the connecting seat 301, and the spring swivel 305 is rotatably connected to one side of the positioning block 304;

[0042] A wiring harness assembly includes the above-mentioned wiring harness connection port and a connecting wiring harness 4. The connecting wiring harness 4 is fixedly installed inside the connecting seat 301, and the wiring harness inside the connecting wiring harness 4 is electrically connected to the data slot inside the plug-in terminal 201.

[0043] When the plug-in terminal 201 is inserted into the fixed port 101, the positioning block 102 is inserted into the connecting slot 2012 under the action of the positioning spring 1021. The cross-section of one end of the block of the positioning block 102 is a right triangle, and when the plug-in terminal 201 moves toward the direction of unplugging the fixed port 101, the straight edge of the block of the positioning block 102 and the straight edge of the groove of the connecting slot 2012 are engaged with each other. In use, the plug-in terminal 201 is directly inserted into the fixed port 101 to realize the connection between the fixed module 1 and the plug-in module 2. When the plug-in terminal 201 is inserted into the fixed port 101, it will be automatically locked in the use position to ensure plugging and unplugging. The stable connection between the terminal 201 and the fixed port 101 realizes data communication transmission. When the plug-in terminal 201 is inserted into the interior of the fixed port 101, the connection harness 4 can realize data communication with the fixed port 101 (data pin inside) through the data slot of the plug-in terminal 201, and under the action of the positioning top spring 1021, the plug-in terminal 201 is inserted into the interior of the fixed port 101, the positioning card block 102 can be automatically plugged into the interior of the connection card slot 2012. Under the clamping action of the positioning card block 102 and the straight edge of the connection card slot 2012, the plug-in terminal 201 cannot move in the direction away from the fixed port 101, thereby locking the plug-in terminal 201 to prevent the plug-in terminal 201 from accidentally falling out of the fixed port 101, and when the connection harness 4 is not pulled by external force, the resistance block 202 will not invade the internal control of the connection card slot 2012 to prevent the plug-in terminal 201 from accidentally falling out, and the use is stable.

[0044] In the embodiment of the present disclosure, a functional tension spring 3051 is provided on the side of the spring swivel 305, and the two ends of the functional tension spring 3051 are respectively fixedly connected to the side of the spring swivel 305 and the outside of the plug-in terminal 201. In use, the connecting mechanism combines the functional component 3 and the plug-in module 2 into a whole for use, and the connecting harness 4 is fixed inside the connecting seat 301. When the connecting harness 4 is pulled by external force, the functional component 3 can provide buffering and protection for the plug-in module 2. When the connecting harness 4 is pulled by external force, the pulling force will directly act on the connecting seat 301. When the pulling force is small, the functional component 3 provides a buffering effect for the plug-in module 2. When the pulling force is large, the functional component 3 provides a protective effect for the plug-in module 2. It has extremely strong flexibility and stability.

[0045] In the embodiment of the present disclosure, an unlocking guide groove 2011 is provided inside the plug-in terminal 201, and the groove body of the unlocking guide groove 2011 is located in the middle of the groove body of the connecting card slot 2012, the groove body thickness of the unlocking guide groove 2011 is less than the groove body thickness of the connecting card slot 2012, and the abutment block 202 is plugged into the inside of the unlocking guide groove 2011. In use, taking the functional component 3 as an example of providing protection for the plug-in module 2, since the pulling force is large at this time, and between the positioning card block 102 and the connecting card slot 201 2, the plug-in terminal 201 cannot move in the direction away from the fixed port 101, so that under the action of external pulling force, the connecting seat 301 will independently move toward the direction of the fixed port 101 and stretch the functional tension spring 3051. The side of the connecting seat 301 is provided with an inclined control groove 3011, and the top of the contact block 202 is provided with a control rod 2021. The control rod 2021 is inserted into the inside of the control groove 3011. When the connecting seat 301 moves, the control groove 3011 can pass through the control rod 2 021 drives the resistance block 202 to move toward the direction of the positioning block 102. When moving, the resistance block 202 can squeeze the positioning block 102 out of the interior of the connecting slot 2012. After the positioning block 102 is squeezed out of the interior of the connecting slot 2012, its locking relationship between the plug-in terminal 201 and the fixed port 101 is released. Thereafter, under the action of the functional tension spring 3051, the plug-in terminal 201 will move toward the direction of the connecting seat 301 to release the connection relationship between the plug-in terminal 201 and the fixed port 101, that is, triggering the protection function of the functional component 3, avoiding the phenomenon that the pulling force will break the connecting harness 4 or damage the fixed module 1 or the plug-in module 2. Based on the above, when the pulling force is small, the movement range of the resistance block 202 is not enough to squeeze the positioning block 102 out of the interior of the connecting slot 2012, and the functional tension spring 3051 will still be stretched a part in the process to buffer the pulling force, thereby triggering the buffering effect of the functional component 3, which is flexible and convenient to use and has extremely strong stability.

[0046] The cam 304 is connected to the control stand 302 by the spring swivel 305, and the cam 304 is connected to the control stand 302 by the spring swivel 305. The movement changes the use position. The change of the use position of the positioning block 304 changes the initial use length of the functional tension spring 3051, which changes the force required to overcome the functional tension spring 3051 for the action of the resistance block 202 squeezing the positioning block 102 out of the interior of the connecting slot 2012 when moving. This force is the triggering force of the protection function. Through this design, the quick disassembly and use of the plug-in terminal 201 is also facilitated. When it is necessary to release the connection relationship between the plug-in terminal 201 and the fixed port 101, it is only necessary to pull the connecting seat 301 or the regulating seat 302 with a force greater than the triggering force of the protection function to release the connection relationship between the plug-in terminal 201 and the fixed port 101 (the protection function of the functional component 3 is manually triggered), and the positioning block 102 and the connecting slot 2012 will not be damaged. It can be repeatedly installed and used later, and has strong flexibility and adaptability.

[0047] The specific usage and function of this embodiment: In the present invention, the triggering force of the protection function of the functional component 3 is adjusted according to the usage environment, which can be achieved by rotating the regulating seat 302. When the regulating seat 302 rotates, it can drive the positioning rods 303 of the two sets of connection mechanisms to rotate synchronously through the gear set. When the positioning rod 303 rotates, it can drive the positioning block 304 to move and change the usage position through the rod body thread. The change of the usage position of the positioning block 304 changes the initial usage length of the functional tension spring 3051, that is, changes the force required to overcome the functional tension spring 3051 for the action of the interference block 202 squeezing the positioning block 102 out of the connecting slot 2012 when moving. This force is the triggering force of the protection function. After the adjustment is completed, the plug and unplug The terminal 201 can be directly inserted into the interior of the fixed port 101 to realize the connection between the fixed module 1 and the plug-in module 2, and when the plug-in terminal 201 is inserted into the interior of the fixed port 101, it will be automatically locked in the use position to ensure the stable connection between the plug-in terminal 201 and the fixed port 101 to realize data communication transmission. When the plug-in terminal 201 is inserted into the interior of the fixed port 101, the connection harness 4 can realize data communication with the fixed port 101 (data pins inside) through the data slot of the plug-in terminal 201, and under the action of the positioning top spring 1021, after the plug-in terminal 201 is inserted into the interior of the fixed port 101, the positioning card block 102 can be automatically plugged into the interior of the connection card slot 2012. Under the clamping action of the clamping block 102 and the straight edge of the connecting card slot 2012, the plug-in terminal 201 cannot move in the direction away from the fixed port 101, thereby locking the plug-in terminal 201 to prevent the plug-in terminal 201 from accidentally falling out of the fixed port 101, and when the connecting harness 4 is not pulled by external force, the resistance block 202 will not invade the internal control of the connecting card slot 2012 to prevent the plug-in terminal 201 from accidentally falling out. The connecting mechanism combines the functional component 3 and the plug-in module 2 into a whole for use, and the connecting harness 4 is fixed inside the connecting seat 301. When the connecting harness 4 is pulled by external force, the functional component 3 can provide buffering and protection for the plug-in module 2, and the pulling force of the connecting harness 4 is reduced when it is pulled by external force. The degree will directly act on the connecting seat 301. When the pulling force is small, the functional component 3 provides a buffering effect for the plug-in module 2. When the pulling force is large, the functional component 3 provides a protective effect for the plug-in module 2. Taking the functional component 3 providing protection for the plug-in module 2 as an example, since the pulling force is large at this time, and under the clamping action of the positioning block 102 and the connecting card slot 2012, the plug-in terminal 201 cannot move in the direction away from the fixed port 101. Therefore, under the action of external pulling force, the connecting seat 301 will independently move toward the direction of the fixed port 101 and lengthen the functional tension spring 3051. When the connecting seat 301 moves, the control slot 3011 can drive the contact block 202 to move toward the direction of the positioning block 102 through the control rod 2021.When the contact block 202 moves, it can squeeze the positioning card block 102 into the interior of the connecting card slot 2012. After the positioning card block 102 is squeezed out of the interior of the connecting card slot 2012, the locking relationship between the plug-in terminal 201 and the fixed port 101 will be released. Thereafter, under the action of the functional tension spring 3051, the plug-in terminal 201 will move toward the direction of the connecting seat 301 to release the connection relationship between the plug-in terminal 201 and the fixed port 101, that is, triggering the protection function of the functional component 3, avoiding the phenomenon that the pulling force will break the connecting wire harness 4 or damage the fixed module 1 or the plug-in module 2. Based on the above, when the pulling force is small, the movement range of the contact block 202 is not enough to loosen the positioning card block 102. The positioning block 102 is squeezed out of the interior of the connecting card slot 2012, and the functional tension spring 3051 will still be stretched partially during this process to buffer the pulling force, thereby triggering the buffering action of the functional component 3. When the plug-in terminal 201 needs to be removed for later maintenance of the connecting harness 4 or automotive equipment, it is only necessary to pull the connecting seat 301 or the regulating seat 302 with a force greater than the force that triggers the protection function to release the connection relationship between the plug-in terminal 201 and the fixed port 101 (the protection function of the functional component 3 is manually triggered) without damaging the positioning block 102 and the connecting card slot 2012. After the maintenance is completed, the plug-in terminal 201 and the fixed port 101 can be connected and used again.

[0048] In another embodiment, the cross-sectional shape of the positioning block 304 is a regular polygon, and a track groove 3012 is provided inside the connecting seat 301. The positioning block 304 is inserted into the track groove 3012. The track groove 3012 can limit the moving trajectory of the positioning block 304, so that the positioning block 304 will not be skewed or twisted during the moving and adjusting position, which will cause the device to get stuck and fail, and the regulation is stable.
