Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, and more specifically, to a shielded wire harness assembly. Background Technology

[0002] For signal transmission circuits in automotive low-voltage wiring harnesses with special requirements, conventional stranded signal wires are used. External electromagnetic interference and radio frequency interference are isolated by a metal shielding layer (such as aluminum foil and / or metal braided mesh) placed on the outside of the stranded signal wires. This ensures stable signal transmission within the stranded signal wires, which is crucial for controlling electrical equipment or instrumentation. In electrical equipment, the metal shielding layer needs to be grounded at both ends; in instrumentation equipment, the metal shielding layer needs to be grounded at one end for optimal performance.

[0003] Currently, the metal shielding layer of signal lines is mainly composed of at least one of aluminum foil and metal braided mesh. In actual use, since the metal shielding layer in the signal line of electrical equipment needs to be grounded at both ends to ensure the shielding effect, the metal shielding layer needs to be brushed, split and twisted with a metal braided mesh brushing and twisting machine before use. At the same time, since the metal shielding layer and the grounding terminal cannot be directly connected, a short section of wire needs to be added to connect the metal shielding layer and the grounding terminal.

[0004] Therefore, those skilled in the art urgently need a shielded wire harness assembly to solve the above problems. Utility Model Content

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] According to a shielded wire harness assembly of this disclosure, such as Figures 1 to 3 As shown, it includes:

[0036] A rigid conductor, the rigid conductor comprising at least one signal line 101 and a shielding metal tube 102 sleeved over the signal line 101;

[0037] The first clamping member 103 is provided with at least one first channel;

[0038] The second clamping member 104 is provided with at least one second channel;

[0039] The first clamping member 103 and the second clamping member 104 are positioned opposite each other to form a clamping channel 105 by the first channel and the second channel being enclosed.

[0040] The shielding metal tube 102 is clamped in the clamping channel 105;

[0041] A current guide is disposed on the first clamping member 103 and electrically connected to the shielding metal tube 102 to conduct the interference current on the shielding metal tube 102 and ground it.

[0042] By placing the signal line 101 inside the shielded metal tube 102, the shielded metal tube 102 isolates external electromagnetic interference and radio frequency interference, ensuring stable signal transmission inside the signal line 101. The shielded metal tube 102, containing the rigid wire, is clamped and fixed by the first clamping member 103 and the second clamping member 104. This allows the current-conducting element located on the first clamping member 103 to be electrically connected to the shielded metal tube 102, thus discharging the interference current generated by external electromagnetic interference and radio frequency interference on the shielded metal tube 102 through grounding. This structure allows the shielded metal tube 102 to be grounded via the current-conducting element, making the grounding structure and method of the shielded metal tube 102 in the shielded cable assembly modular, simplifying the process, saving assembly time for the shielded wire harness, and streamlining the production process.

[0043] The shielding metal tube 102 can be made of conductive materials such as aluminum, copper, aluminum alloy, copper alloy, and copper-aluminum alloy; the signal line 101 can be a twisted wire formed by at least two conductors capable of transmitting signals.

[0044] According to one embodiment of a shielded wire harness assembly disclosed herein, the flow guide includes a first flow guide 107, a second flow guide 108, and a connector 109 connecting the first flow guide 107 and the second flow guide 108; the first flow guide 107 is disposed on the inner circumferential surface of the first channel.

[0045] The first guide 107 is disposed on the inner surface of the first channel so that when the first clamp 103 and the second clamp 104 are connected, the first guide 107 is electrically connected to the shielded metal tube 102 so that the interference current generated on the shielded metal tube 102 due to external electromagnetic interference and radio frequency interference is collected by the connector 109 to the second guide 108, and then discharged through the grounding structure.

[0046] Specifically, the first clamping member 103 has a stepped portion 110 at one end along the extension direction of the rigid wire;

[0047] The second flow guide 108 is disposed on the surface of the stepped portion 110 facing the first channel; the second flow guide 108 is electrically connected to the grounding terminal 112 disposed on the first clamping member 103.

[0048] By providing a stepped portion 110 on the first clamping member 103, an installation position is provided for the second current guide 108 and the grounding terminal 112, so as to discharge the interference current generated on the shielded metal tube 102 due to external electromagnetic interference and radio frequency interference.

[0049] According to one embodiment of a shielded wire harness assembly disclosed herein, the flow guide further includes an additional flow guide 111, which is disposed on the inner circumferential surface of the second channel and is electrically connected to the shielded metal tube 102 and the flow guide.

[0050] By electrically connecting the additional flow guide 111 to the shielded metal tube 102 and the first flow guide 107 of the flow guide, the shielded metal tube 102 can have a better shielding effect, so as to ensure that the signal line 101 can transmit signals stably.

[0051] According to one embodiment of a shielded wire harness assembly disclosed herein, a grounding terminal 112 is included, which is disposed on the first clamping member 103 and electrically connected to the current guide member.

[0052] By providing a grounding terminal 112 on the first clamping member 103, it is convenient to connect the grounding terminal 112 to the current guide provided on the first clamping member 103, so that the metal shielding tube 102 is connected to the grounding terminal 112 via the current guide, so as to discharge the interference current generated on the shielding metal tube 102 due to external electromagnetic interference and radio frequency interference.

[0053] Specifically, the grounding terminal 112 has an assembly through hole 113 and a claw structure 114. The assembly through hole 113 clamps and connects the current guide, and the claw structure 114 clamps the stepped portion 110 of the first clamping member 103.

[0054] By setting the gripper structure 114, it is convenient for the assembly personnel to assemble the grounding terminal 112 to the stepped portion 110 of the first clamping member 103; by assembling the through hole 113, the guide member can be well clamped, so that the assembly personnel can quickly fix the grounding terminal 112 to the stepped portion 110 of the first clamping member 103 and connect it to the guide member.

[0055] More specifically, the gripper structure 114 includes a first gripper 115 and a second gripper 116. The side surfaces of the first gripper 115 and the second gripper 116 facing each other are respectively provided with a protrusion 117. When the gripper structure 114 clamps the stepped portion 110, the protrusion 117 abuts against the side surface of the stepped portion 110 that is away from the guide member.

[0056] By setting the protrusion 117, the stepped portion 110 is restricted from disengaging from the opening direction of the gripper structure 114, so that the grounding terminal 112 is firmly set on the first connector 109.

[0057] More specifically, the sidewall of the assembly through hole 113 is provided with a slit 118 that extends to the external space, so that the assembly through hole 113 deforms to allow the second guide member 108 of the guide member to enter.

[0058] The gap 118 allows the assembler to easily insert the second guide 108 into the assembly through hole 113 so that the guide can be connected to the grounding terminal 112; at the same time, it allows the assembler to easily separate the second guide 108 from the grounding terminal 112 while facilitating the removal of the grounding terminal 112 from the first connector 109.

[0059] According to one embodiment of a shielded wire harness assembly disclosed herein, a snap-fit ​​structure 119 is also included, through which the first clamping member 103 and the second clamping member 104 are detachably connected.

[0060] The first clamping member 103 and the second clamping member 104 are combined and separated by the snap-fit ​​structure 119, so that the assembly personnel can assemble the rigid wires in the clamping channel 105 to form a shielded wire harness assembly.

[0061] In a specific implementation, the snap-fit ​​structure 119 includes a snap-fit ​​portion disposed on one of the first clamping member 103 and the second clamping member 104, and a snap-fit ​​groove disposed on the other of the two that snaps into the snap-fit ​​portion 120.

[0062] According to one embodiment of a shielded wire harness assembly disclosed herein, both the first channel and the second channel are arc-shaped channels.

[0063] When the first channel and the second channel are positioned vertically opposite each other, the corresponding arc-shaped channels form a circle, matching the outer periphery of the shielding metal tube 102, so as to connect the first guide member 107 and the additional guide member 111 to each other and to electrically connect them to the shielding metal tube 102.

[0064] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
