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 Art

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

[0003] However, the connectors of conventional wire harness assemblies have the following drawbacks because they are locked by simple engaging tools after connection. 1. It does not have a protection function. When the wire harness is pulled by an external force, damage or breakage of the engaging tool of the connection terminal or breakage of the wire harness is likely to occur, and the engaging tool of the connection terminal cannot be locked during subsequent use, resulting in a phenomenon that the connection terminal and the connector cannot be reliably connected, affecting the normal use of automotive equipment and reducing stability. 2. It does not have a quick removal structure. After the connection terminal is attached, if it needs to be removed, the connection terminal can be removed by prying open the engaging tool with a tool (such as a driver). The procedure is cumbersome, and when prying open the engaging tool, breakage or damage of the engaging tool is likely to occur, affecting subsequent assembly and use, and lacking flexibility and practicality.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, in order to make the objectives, technical means, and advantages of the embodiments of the present invention clearer, while referring to the drawings of the embodiments of the present invention, the technical means of the embodiments of the present invention will be clearly and completely described. It goes without saying that the described embodiments are some of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained on the premise that those skilled in the art do not perform creative activities all belong to the protection scope of the present invention.

[0022] Please refer to FIGS. 1 to 10. (Embodiment 1) The present invention provides a wire harness connector and a wire harness assembly, which includes a fixed connector 101 and a positioning engagement block 102. The fixed connector 101 is fixedly mounted on an automotive electronic device. The positioning engagement block 102 includes a fixing module 1 inserted on the top of the fixed connector 101, a plug-in terminal 201, and an abutting block 202. The plug-in terminal 201 is inserted into the fixed connector 101. The abutting block 202 includes an insertion / extraction module 2 inserted into the plug-in terminal 201. The connection receiving part 301, the adjustment seat part 302, the positioning rod 303, the positioning block 304, and the spring rotating ring 305 are included. The connection receiving part 301 is inserted into the side surface of the plug-in terminal 201. The adjustment seat part 302 is rotatably connected to the outside of the connection receiving part 301. The positioning rod 303 is rotatably connected to the inside of the connection receiving part 301. The positioning block 304 is inserted into the connection receiving part 301. The spring rotating ring 305 includes a functional assembly 3 rotatably connected to one side of the positioning block 304. A wire harness assembly comprising the above-described wire harness connector, further comprising a connection wire harness that is fixedly mounted inside the connection receiving portion 301 and electrically connects the internal wire harness to a data slot inside the plug-in terminal 201.

[0023] In an embodiment of the present disclosure, a positioning top spring 1021 is provided on the side surface of the positioning engagement block 102. Both ends of the positioning top spring 1021 are respectively in contact with the inside of the positioning engagement block 102 and the inside of the fixed connector 101. 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, under the action of the positioning top spring 1021, the positioning engagement block 102 is inserted into the connection engagement groove 2012. One end of the block body of the positioning engagement block 102 has a right-angled triangle cross-section. 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 locked. 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 insertion and extraction 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 connection 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. And under the action of the positioning top spring 1021, after the plug-in terminal 201 is inserted into the fixed connector 101, the positioning engagement block 102 can be automatically inserted into the connection engagement groove 2012. Under the locking action of the straight side of the groove body of the positioning engagement block 102 and the connection engagement groove 2012, the plug-in terminal 201 cannot move in the direction away from the fixed connector 101, locking the plug-in terminal 201 and preventing the plug-in terminal 201 from accidentally falling out of the fixed connector 101. And when the connection wire harness 4 is not pulled by an external force, the abutting block 202 does not enter the internal cavity of the connection engagement groove 2012, preventing the plug-in terminal 201 from accidentally falling out and making the use stable.

[0024] In an embodiment of the present disclosure, a functional tension spring 3051 is provided on the side surface of the rotary ring 305 for the spring, and both ends of the functional tension spring 3051 are respectively connected and fixed to the side surface of the rotary ring 305 for the spring and the outside of the plug-in terminal 201. During use, the connection mechanism assembles the functional assembly 3 and the insertion and extraction module 2 as a whole, and the connection wire harness 4 is fixed inside the connection receiving portion 301. When the connection wire harness 4 is pulled by an external force, the functional assembly 3 can exert a buffering and protecting function on the insertion and extraction module 2. When the connection wire harness 4 is pulled by a force, the pulling force directly acts on the connection receiving portion 301. When the pulling force is small, the functional assembly 3 exerts a buffering function on the insertion and extraction module 2. When the pulling force is large, the functional assembly 3 exerts a protecting function on the insertion and extraction module 2, and the flexibility and stability are extremely high.

[0025] In an embodiment of the present disclosure, a lock release guide groove 2011 is provided inside the plug-in terminal 201. The groove body of the lock release guide groove 2011 is located at the center of the groove body of the connection engaging groove 2012. The thickness of the groove body of the lock release guide groove 2011 is smaller than the thickness of the groove body of the connection engaging groove 2012. The abutting block 202 is inserted into the lock release guide groove 2011. During use, taking the example that the functional assembly 3 exerts a protection function on the insertion and extraction module 2, at this time, the pulling force is large, and under the locking action of the positioning engaging block 102 and the connection engaging groove 2012, the plug-in terminal 201 cannot move in the direction away from the fixed connector 101. Due to the pulling action of the external force, the connection receiving part 301 moves independently in the direction of the fixed connector 101, stretching the functional tension spring 3051. An inclined control groove 3011 is provided on the side surface of the connection receiving part 301, and a control rod 2021 is provided at the top of the abutting block 202. The control rod 2021 is inserted into the control groove 3011. When the connection receiving part 301 moves, the control groove 3011 can move the abutting block 202 in the direction of the positioning engaging block 102 through the control rod 2021. When the abutting block 202 moves, the positioning engaging block 102 can be pushed out of the connection engaging groove 2012. After the positioning engaging block 102 is pushed out of the connection engaging groove 2012, the lock between the plug-in terminal 201 and the fixed connector 101 is released. Therefore, then, under the action of the functional tension spring 3051, the plug-in terminal 201 moves in the direction of the connection receiving part 301 to release the connection between the plug-in terminal 201 and the fixed connector 101, that is, trigger the protection function of the functional assembly 3 to avoid the breakage of the connection wire harness 4 due to the pulling force or the damage reduction of the fixing module 1 or the insertion and extraction module 2. According to the above, when the pulling force is small, the moving range of the abutting block 202 cannot push the positioning engaging block 102 out of the connection engaging groove 2012, and the functional tension spring 3051 remains partially stretched in this process, buffering the pulling force, thereby triggering the buffering function of the functional assembly 3, making it easy to use, flexible, and extremely stable.

[0026] In an embodiment of the present disclosure, the positioning rod 303, the positioning block 304, and the spring rotating ring 305 jointly constitute a connection mechanism. Two sets of connection mechanisms are provided, and the two sets of connection mechanisms are symmetrically arranged outside the connection receiving portion 301. The positioning rods 303 of the two sets of connection mechanisms are connected to the adjustment base portion 302 through a gear set so that power can be transmitted. During use, the pulling force that triggers the protection function of the functional assembly 3 can be freely adjusted, and it can be adapted to installation and use in different environments. This is realized by rotating the adjustment base portion 302. When the adjustment base portion 302 rotates, the positioning rods 303 of the two sets of connection mechanisms can be rotated simultaneously through the gear set. A threaded portion is provided on the outside of the rod body of the positioning rod 303. The positioning rod 303 is tightened inside 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 the use position. When the use position of the positioning block 304 is changed, the initial use length of the functional tension spring 3051 is changed. When the abutting block 202 moves, the force required to overcome the functional tension spring 3051 for the operation of pushing the positioning engagement block 102 out of the connection engagement groove 2012 changes. This force is the force that triggers the protection function. Moreover, due to this design, the quick removal of the plug-in terminal 201 is also facilitated. When it is necessary to disconnect the connection between the plug-in terminal 201 and the fixed connector 101, when the connection receiving portion 301 or the adjustment base 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 disconnected without damaging the positioning engagement block 102 and the connection engagement groove 2012. Then, it can be repeatedly installed and used, and the flexibility and adaptability are extremely high.

[0027] Specific usage method and function of this embodiment: In the present invention, according to the usage environment, the force that triggers the protection function of the functional assembly 3 is adjusted, which is realized by rotating the adjustment seat portion 302. When the adjustment seat portion 302 rotates, the positioning rods 303 of the two sets of connection mechanisms can be simultaneously rotated through the gear set. When the positioning rod 303 rotates, the positioning block 304 can be moved through the threaded portion of the rod body to change the usage position. When the usage position of the positioning block 304 is changed, the initial usage length of the functional tension spring 3051 is changed. When the abutting block 202 moves, the force required to overcome the functional tension spring 3051 changes when the positioning engagement block 102 is pushed out from inside the connection engagement groove 2012. This force is the force that triggers the protection function. After the adjustment is completed, when the plug-in terminal 201 is directly inserted into the fixed connector 101, the connection usage between the fixed module 1 and the plug-in and unplugging module 2 can be realized. After the plug-in terminal 201 is inserted into the fixed connector 101, its usage 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 connection 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. And under the action of the positioning top spring 1021, after the plug-in terminal 201 is inserted into the fixed connector 101, 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 portion 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, thus locking the plug-in terminal 201 and preventing the plug-in terminal 201 from accidentally falling out of the fixed connector 101. And when the connection wire harness 4 is not pulled by an external force, the abutting block 202 will not enter the internal cavity of the connection engagement groove 2012, preventing the plug-in terminal 201 from accidentally falling out. The connection mechanism assembles the functional assembly 3 and the plug-in and unplugging module 2 as a whole, and the connection wire harness 4 is fixed inside the connection receiving portion 301.When the connection wire harness 4 is pulled by an external force, the functional assembly 3 can cause the insertion and extraction module 2 to function as a buffer and a protector. When the connection wire harness 4 is pulled by a force, the pulling force directly acts on the connection receiving part 301. When the pulling force is small, the functional assembly 3 causes the insertion and extraction module 2 to function as a buffer. When the pulling force is large, the functional assembly 3 causes the insertion and extraction module 2 to function as a protector. Taking the case where the functional assembly 3 causes the insertion and extraction module 2 to function as a protector as an example, at this time, the pulling force is large, and under the locking action of the positioning engagement block 102 and the connection engagement groove 2012, the plug-in terminal 201 cannot move in the direction away from the fixed connector 101. Due to the pulling action of the external force, the connection receiving part 301 moves independently in the direction of the fixed connector 101, stretching the functional tension spring 3051. When the connection receiving part 301 moves, the control groove 3011 can move the abutting block 202 in the direction of the positioning engagement block 102 through the control rod 2021. When the abutting block 202 moves, the positioning engagement block 102 can be pushed out from the inside of the connection engagement groove 2012. After the positioning engagement block 102 is pushed out from the inside of the connection engagement groove 2012, the lock between the plug-in terminal 201 and the fixed connector 101 is released. Therefore, then, under the action of the functional tension spring 3051, the plug-in terminal 201 moves in the direction of the connection receiving part 301 to release the connection between the plug-in terminal 201 and the fixed connector 101, that is, trigger the protection function of the functional assembly 3 to avoid the breakage of the connection wire harness 4 due to the pulling force or the reduction of damage to the fixing module 1 or the insertion and extraction module 2.According to the above, when the pulling force is small, the moving range of the abutting block 202 cannot push the positioning engagement block 102 out of the internal connection engagement groove 2012. The functional tension spring 3051 remains partially stretched during this process, and by buffering the pulling force, the buffer function of the functional assembly 3 is triggered. Subsequently, when it is necessary to inspect the connection wire harness 4 or automotive equipment and remove the plug-in terminal 201, when the connection receiving part 301 or the adjustment seat part 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 and used.

[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 part 301, and the positioning block 304 is inserted into the rail groove 3012. Since the rail groove 3012 can limit the movement trajectory of the positioning block 304, when the positioning block 304 moves to adjust the use position, there will be no distortion or torsion, and the stack failure phenomenon of the device will not occur, and the adjustment is stable.

[0029] In this specification, attention should be paid to the following points.

[0030] 1. The drawings of the embodiments of the present disclosure only relate to the structures according to the embodiments of the present disclosure. For other structures, normal designs can be referred to. 2.
