Description

[Technical field]

[0001] The present invention relates to the technical field of wire harness connectors, and in particular to wire harness connectors and wire harness assemblies. [Background technology]

[0002] An automotive wire harness assembly is an important part of an automobile's electrical system that can realize power supply and communication between each part of the automobile, and is a channel for transmitting information such as automobile driving instructions and safety protection signals. Currently, both ends of a wire harness assembly are connected and communicated with the automobile's power supply, on-board computer, and automobile devices (such as rearview mirrors, lights, cameras, audio, etc.) through connectors.

[0003] However, the connectors of the conventional wire harness assemblies have the following drawbacks since they are locked by a simple engaging device after connection. 1. Without a protective function, when the wire harness is pulled by an external force, the engaging device of the connection terminal is easily damaged or broken, or the wire harness is easily cut. During subsequent use, the engaging device of the connection terminal cannot be locked, and the connection terminal and the connector are easily unable to be securely connected, which affects the normal use of the automotive equipment and reduces stability. 2. There is no quick release structure, and if the connecting terminal needs to be removed after it is installed, the connecting terminal can be removed by prying open the engaging device with a tool (such as a screwdriver), which is a cumbersome procedure and is likely to cause breakage or damage to the engaging device when prying it open, which will affect subsequent assembly and use, and is poor in flexibility and practicality.

[0023] In the embodiment of the present disclosure, a positioning top spring 1021 is provided on the side of the positioning engagement block 102, both ends of which abut against the inside of the positioning engagement block 102 and the inside of the fixed connector 101 respectively, and a connection engagement groove 2012 is provided inside the plug-in terminal 201, when the plug-in terminal 201 is inserted into the fixed connector 101, the positioning engagement block 102 is inserted into the connection engagement groove 2012 under the action of the positioning top spring 1021, and the cross section of one end of the block body of the positioning engagement block 102 forms a right-angled triangle, and when the plug-in terminal 201 moves in the direction of pulling out the fixed connector 101, the straight side of the block body of the positioning engagement block 102 and the straight side of the groove body of the connection engagement groove 2012 are engaged. During use, when the plug-in terminal 201 is directly inserted into the fixed connector 101, the connection use between the fixed module 1 and the plug-in module 2 can be realized. After the plug-in terminal 201 is inserted into the fixed connector 101, the use position is automatically locked, ensuring a stable connection between the plug-in terminal 201 and the fixed connector 101, and realizing data communication and transmission. After the plug-in terminal 201 is inserted into the fixed connector 101, the connecting wire harness 4 can realize data communication with the fixed connector 101 (internal data pins) through the data slot of the plug-in terminal 201; after the plug-in terminal 201 is inserted into the fixed connector 101 under the action of the positioning top spring 1021, the positioning engagement block 102 can be automatically inserted into the connection engagement groove 2012; under the locking action of the positioning engagement block 102 and the straight side part of the groove body of the connection engagement groove 2012, the plug-in terminal 201 cannot move in the direction away from the fixed connector 101, thereby locking the plug-in terminal 201 and preventing it from accidentally falling off from the fixed connector 101; when the connecting wire harness 4 is not pulled by an external force, the abutment block 202 will not enter the internal cavity of the connection engagement groove 2012, thereby preventing the plug-in terminal 201 from accidentally falling off, and the use is stable.

[0024] In the embodiment of the present disclosure, a functional tension spring 3051 is provided on the side of the spring rotating ring 305, and both ends of the functional tension spring 3051 are connected and fixed to the side of the spring rotating ring 305 and the outside of the plug-in terminal 201, respectively. During use, the connection mechanism as a whole assembles the functional assembly 3 and the plug-in module 2, and the connecting wire harness 4 is fixed inside the connection receiving part 301. When the connecting wire harness 4 is pulled by an external force, the functional assembly 3 can provide a buffering and protection function for the plug-in module 2, and when the connecting wire harness 4 is pulled by a force, the pulling force acts directly on the connection receiving part 301, and when the pulling force is small, the functional assembly 3 provides a buffering function for the plug-in module 2, and when the pulling force is large, the functional assembly 3 provides a protection function for the plug-in module 2, and it is also very flexible and stable.

[0025] In an embodiment of the present disclosure, an unlocking guide groove 2011 is provided inside the plug-in terminal 201, the groove body of the unlocking guide groove 2011 is located at the center of the groove body of the connection engagement groove 2012, the thickness of the groove body of the unlocking guide groove 2011 is smaller than the thickness of the groove body of the connection engagement groove 2012, and the abutment block 202 is inserted into the unlocking guide groove 2011. For example, when the functional assembly 3 protects the plug-in module 2 during use, the pulling force is large, and the plug-in terminal 201 cannot move away from the fixed connector 101 under the locking action of the positioning engagement block 102 and the connection engagement groove 2012. Therefore, the connection receiving part 301 moves independently toward the fixed connector 101 due to the pulling action of the external force, and the functional tension spring 3051 is stretched. The connection receiving part 301 is provided with an inclined control groove 3011 on its side, and a control rod 2021 is provided at the top of the butt block 202. The control rod 2021 is inserted into the control groove 3011. When the connection receiving part 301 moves, the control groove 3011 contacts the butt block 101 through the control rod 2021. 202 can be moved toward the positioning engagement block 102, and when the abutment block 202 moves, it can push the positioning engagement block 102 out from inside the connection engagement groove 2012, and after the positioning engagement block 102 is pushed out from inside the connection engagement groove 2012, the lock between the plug-in terminal 201 and the fixed connector 101 is released, and then under the action of the functional tension spring 3051, the plug-in terminal 201 moves toward the connection receiving portion 301 to release the connection between the plug-in terminal 201 and the fixed connector 101, that is, to trigger the protection function of the functional assembly 3 to prevent the connecting wire harness 4 from being broken or the fixing module 1 or the plug-in module 2 from being damaged due to the pulling force. According to the above, when the pulling force is small, the movement range of the abutment block 202 cannot push the positioning engagement block 102 out from the inside of the connection engagement groove 2012, and the functional tension spring 3051 remains partially stretched during the process, thereby buffering the pulling force and triggering the buffering function of the functional assembly 3, which is easy to use, flexible and extremely stable.

[0026] In the embodiment of the present disclosure, the positioning rod 303, the positioning block 304 and the spring rotating ring 305 jointly constitute a connection mechanism, which is provided with two sets of connection mechanisms, and the two sets of connection mechanisms are symmetrically arranged outside the connection receiving part 301, and the positioning rods 303 of the two sets of connection mechanisms are drivably connected to the adjustment seat 302 through a gear set. During use, the pulling force that triggers the protection function of the functional assembly 3 can be freely adjusted and adapted to the installation and use in different environments, which is realized by rotating the adjustment seat 302. When the adjustment seat 302 rotates, the positioning rods 303 of the two sets of connection mechanisms can be rotated simultaneously through the gear set, and the outside of the rod body of the positioning rod 303 is provided with a threaded portion, the positioning rod 303 is fastened to the inside of the positioning block 304 through the threaded portion of the rod body, and the rod body of the positioning rod 303 passes through the inside of the spring rotating ring 305. When the positioning rod 303 rotates, the positioning block 304 can be moved through the threaded portion of the rod body to change its position of use. When the position of the positioning block 304 is changed, the initial length of the functional tension spring 3051 is changed. When the abutting block 202 moves, the force required to push the positioning engagement block 102 out of the connection engagement groove 2012 and overcome the functional tension spring 3051 changes. This force is the force that triggers the protective function. This design also facilitates quick removal of the plug-in terminal 201. When it is necessary to release the connection between the plug-in terminal 201 and the fixed connector 101, when the connection receiving portion 301 or the adjustment seat portion 302 is pulled with a force exceeding the force that triggers the protective function, the connection between the plug-in terminal 201 and the fixed connector 101 (the protective function of the functional assembly 3 is manually triggered) can be released without damaging the positioning engagement block 102 and the connection engagement groove 2012. The assembly can be repeatedly installed and used thereafter, and has very high flexibility and adaptability.

[0027] Specific usage method and function of this embodiment: In the present invention, the force that triggers the protection function of the functional assembly 3 is adjusted according to the usage environment, and is realized by rotating the adjustment seat 302. When the adjustment seat 302 rotates, the positioning rods 303 of the two connection mechanisms can be rotated simultaneously through the gear set, and when the positioning rods 303 rotate, the positioning block 304 can be moved through the threaded part of the rod body to change the usage position, and when the usage position of the positioning block 304 is changed, the initial usage length of the functional tension spring 3051 is changed, and when the butting block 202 moves, the action force required for the action of pushing the positioning engagement block 102 out of the inside of the connection engagement groove 2012 to overcome the functional tension spring 3051 changes, and this force is the force that triggers the protection function, and after the adjustment is completed, when the plug-in terminal 201 is directly inserted into the inside of the fixed connector 101, the connection use between the fixed module 1 and the plug-in module 2 can be realized. After the plug-in terminal 201 is inserted into the fixed connector 101, the use position is automatically locked, ensuring a stable connection between the plug-in terminal 201 and the fixed connector 101, and realizing data communication and transmission. After the plug-in terminal 201 is inserted into the fixed connector 101, the connecting wire harness 4 can realize data communication with the fixed connector 101 (internal data pins) through the data slot of the plug-in terminal 201. After the plug-in terminal 201 is inserted into the fixed connector 101 under the action of the positioning top spring 1021, the positioning engagement block 102 can be automatically inserted into the connection engagement groove 2012, and the plug-in terminal 201 can be automatically locked into the connection engagement groove 2012 under the locking action of the positioning engagement block 102 and the straight side of the groove body of the connection engagement groove 2012. 01 cannot move in a direction away from the fixed connector 101, thereby locking the plug-in terminal 201 and preventing the plug-in terminal 201 from accidentally falling out of the fixed connector 101. When the connecting wire harness 4 is not pulled by an external force, the abutment block 202 will not enter the internal cavity of the connecting engagement groove 2012, preventing the plug-in terminal 201 from accidentally falling out. The connection mechanism as a whole assembles the functional assembly 3 and the insertion / removal module 2, and the connecting wire harness 4 is fixed inside the connection receiving portion 301.When the connecting wire harness 4 is pulled by an external force, the functional assembly 3 can provide a buffering and protective function for the plug-in module 2. When the connecting wire harness 4 is pulled by a force, the pulling force acts directly on the connection receiving portion 301. When the pulling force is small, the functional assembly 3 provides a buffering function for the plug-in module 2. When the pulling force is large, the functional assembly 3 provides a protective function for the plug-in module 2. Taking the functional assembly 3 providing a protective function for the plug-in module 2 as an example, when the pulling force is large and the plug-in terminal 201 cannot move in a direction away from the fixed connector 101 due to the locking action of the positioning engagement block 102 and the connection engagement groove 2012, the connection receiving portion 301 moves independently toward the fixed connector 101 due to the pulling action of the external force, and the functional tension spring 3051 is stretched, and the connection When the receiving part 301 moves, the control groove 3011 can move the butt block 202 toward the positioning engagement block 102 through the control rod 2021, and when the butt block 202 moves, it can push the positioning engagement block 102 out of the connection engagement groove 2012. After the positioning engagement block 102 is pushed out of the connection engagement groove 2012, the lock between the plug-in terminal 201 and the fixed connector 101 is released, and then under the action of the functional tension spring 3051, the plug-in terminal 201 moves toward the connection receiving part 301 to release the connection between the plug-in terminal 201 and the fixed connector 101, that is, to trigger the protection function of the functional assembly 3 to prevent the connecting wire harness 4 from being broken or the fixing module 1 or the plug-in / unpluggable module 2 from being damaged due to the pulling force.According to the above, when the pulling force is small, the movement range of the abutting block 202 is not enough to push the positioning engagement block 102 out from the inside of the connection engagement groove 2012, and the functional tension spring 3051 remains partially stretched during the process, thereby buffering the pulling force and triggering the buffering function of the functional assembly 3. If the connecting wire harness 4 or the automotive equipment is then inspected and the plug-in terminal 201 needs to be removed, when the connection receiving portion 301 or the adjustment seat portion 302 is pulled with a force exceeding the force that triggers the protection function, the connection between the plug-in terminal 201 and the fixed connector 101 (the protection function of the functional assembly 3 is manually triggered) can be released, without damaging the positioning engagement block 102 and the connection engagement groove 2012. After the inspection is completed, the plug-in terminal 201 can be connected to the fixed connector 101 for use.

[0028] In another embodiment, the cross-sectional shape of the block body of the positioning block 304 is a regular polygon, a rail groove 3012 is provided inside the connection receiving portion 301, the positioning block 304 is inserted into the rail groove 3012, and the rail groove 3012 can limit the moving trajectory of the positioning block 304. Therefore, when the positioning block 304 moves to adjust the usage position, distortion or twisting will not occur, which will cause the device to fail due to being stuck, and the adjustment is stable.
