Description

Technical Field

[0001] This utility model relates to the field of wire harness production technology, and in particular to a wire harness fixing device with shielding function. Background Technology

[0002] A wire harness is an assembly composed of multiple insulated wires and cables arranged in a specific direction and pattern, often supplemented by insulating sheaths, binding straps, and other components. It is widely used in automobiles, electronic equipment, industrial machinery, and other fields. Like a "nerve network," it undertakes the core functions of power transmission and signal transmission, connecting dispersed electrical components in an orderly manner to ensure the coordinated operation of various parts of the equipment. Wire harness fixing devices are structural components used to constrain and position wire harnesses. Their core function is to stably fix the wire harness in a preset position inside the equipment, preventing displacement or wear caused by vibration, friction, or external pulling forces.

[0003] To address this, patent publication CN202633845U discloses a wire harness fixing device, belonging to the technical field of forklift components. The wire harness fixing device is characterized by including a wiring connection plate, with several wires extending from one end of the connection plate, the other end of each wire connected to a junction box, and a fixing sleeve wrapped around each wire. This utility model's wire harness fixing device has a simple structural design, using the fixing sleeve to secure complex wiring together, thus preventing misconnection or incorrect wiring.

[0004] The aforementioned wire harness fixing device has a simple structural design, which uses a fixing sleeve to fix complex wires together to avoid misconnection or incorrect connection. However, during use, the wire harness may shift or fall off, so it is necessary to fix the wire harness. Utility Model Content

[0005] The purpose of this invention is to provide a wire harness fixing device with shielding function to solve the defects of existing wire harness fixing devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wire harness fixing device with shielding function, including a base plate;

[0007] Mounting screws are installed at both ends of the top of the base plate, and a housing is installed at the top of the base plate, with connecting blocks installed on both sides of the housing.

[0008] The connecting block has an opening inside, the outer shell has a baffle inside, and the top of the outer shell has a positioning structure.

[0009] The positioning structure includes a threaded sleeve installed at the top of the outer shell, a threaded rod passing through the top of the threaded sleeve, a positioning block installed at the bottom of the threaded rod, and a rotating block installed at the top of the threaded rod.

[0010] In use, the wire harness can first enter the housing through the opening. The baffle can separate the wire harness. The device can be fixed by the mounting screws. The threaded sleeve and the threaded rod form a threaded connection. The rotating block can be grasped to drive the threaded rod to rotate. The rotation of the threaded rod will drive the threaded rod to rise and fall. The rise and fall of the threaded rod can drive the positioning block to rise and fall. The rise and fall of the positioning block can press the wire harness at the bottom to position the wire harness and prevent the wire harness from falling off.

[0011] Furthermore, the mounting screws and the base plate form a threaded connection, and the mounting screws are symmetrically distributed about the central axis of the base plate, so that the device can be fixed by the mounting screws.

[0012] Furthermore, a heat dissipation structure is installed at the top of the housing. The heat dissipation structure includes a heat-conducting block installed at the top of the housing, and a heat sink is provided at the top of the heat-conducting block. The heat dissipation structure can dissipate heat from the housing and the wiring harness.

[0013] Furthermore, the heat sink has through holes inside, which are arranged at equal intervals inside the heat sink, thereby increasing the surface area of ​​the heat sink.

[0014] Furthermore, the shell has an internal shielding structure, which includes a shielding coating on the outer side of the shell and a metal fiber layer on the inner side of the shielding coating. The shielding structure can enhance the shielding effect of the shell.

[0015] Furthermore, a shielding layer is provided on the inner side of the metal fiber layer, and the outer diameter of the shielding layer is smaller than the inner diameter of the metal fiber layer. The shielding layer can enhance the shielding effect of the outer shell.

[0016] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the threaded sleeve is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the threaded sleeve are threadedly connected, and the rotation of the threaded rod can drive the positioning block to rise and fall.

[0017] The wire harness fixing device with shielding function provided by this utility model has the following advantages: during use, the wire harness can be fixed by the positioning structure to prevent the wire harness from falling off; the heat dissipation structure can quickly dissipate heat from the outer shell; and the shielding structure can enhance the shielding effect of the outer shell.

[0018] By providing a threaded sleeve at the top of the outer casing, the threaded sleeve and the threaded rod form a threaded connection. The rotating block can be gripped to drive the threaded rod to rotate. The rotation of the threaded rod will cause the threaded rod to rise and fall. The rise and fall of the threaded rod can drive the positioning block to rise and fall. The rise and fall of the positioning block can press the wire harness at the bottom end to position the wire harness and prevent the wire harness from falling off. At the same time, the adjacent threaded rods are arranged in an alternating manner, which makes it easier for the rotating block to grip. This achieves the wire harness fixing device, which facilitates the fixing of the wire harness.

[0019] By installing a heat sink on the top of the heat-conducting block, both the heat sink and the heat-conducting block are made of brass. Brass has a high thermal conductivity, which can quickly transfer the heat from the device casing to the heat sink. The through holes on the surface increase the three-dimensional surface area of ​​the heat sink, allowing the internal low-heat exchange area to participate in heat dissipation. At the same time, the heat exchange efficiency with the air is directly related to the contact area between the heat sink and the air. The larger the surface area, the more heat is transferred per unit time. The increased surface area enhances the thermal radiation effect and strengthens the heat dissipation effect, thereby achieving the purpose of facilitating heat dissipation in the wire harness fixing device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 One embodiment of this utility model is a wire harness fixing device with shielding function, which includes a base plate 1.

[0028] Mounting screws 2 are installed at both ends of the top of the base plate 1. The mounting screws 2 and the base plate 1 form a threaded connection. The mounting screws 2 are symmetrically distributed about the central axis of the base plate 1.

[0029] The top of the base plate 1 is equipped with a shell 3. The shell 3 has a shielding structure 9 inside. The shielding structure 9 includes a shielding coating 902 applied to the outer side of the shell 3, a metal fiber layer 901 on the inner side of the shielding coating 902, and a shielding layer 903 on the inner side of the metal fiber layer 901. The outer diameter of the shielding layer 903 is smaller than the inner diameter of the metal fiber layer 901.

[0030] See attached document Figure 5 As shown, the shielding structure 9 achieves electromagnetic interference blocking through multi-layer synergy. The shielding coating 902 on the surface of the outer shell 3 is mostly composed of resin as the base material, combined with conductive fillers such as copper powder and graphene. It can reflect and absorb external high-frequency interference, forming the first line of protection. The inner metal fiber layer 901 is woven from stainless steel fibers. With the conductive network between the fibers, it intercepts low- and medium-frequency interference and disperses energy through conduction, while enhancing the flexibility of the overall structure. The innermost shielding layer 903 is usually made of copper foil. It uses high conductivity to build a closed barrier, further reflecting interference signals that have not been weakened by the outer layer and preventing them from intruding into the internal wiring harness. The three layers form a progressive protection of reflection, absorption, and re-reflection from the outside to the inside. Through the complementary properties of the materials, a wide-band electromagnetic shielding effect is achieved.

[0031] A heat dissipation structure 6 is installed on the top of the outer shell 3. The heat dissipation structure 6 includes a heat-conducting block 601 installed on the top of the outer shell 3, a heat sink 602 provided on the top of the heat-conducting block 601, and through holes 603 provided inside the heat sink 602. The through holes 603 are arranged at equal intervals inside the heat sink 602.

[0032] See attached document Figure 1-3As shown, both the heat sink 602 and the heat-conducting block 601 are made of brass. The brass heat sink 602 achieves heat dissipation through the synergy of material properties and structural design. Brass has a high thermal conductivity, which can quickly transfer the heat from the outer shell 3 of the device to the heat sink 602. The heat sink 602 is arranged at equal intervals to provide an orderly channel for air convection. Hot air rises and cold air replenishes to form a circulation, avoiding airflow congestion caused by uneven spacing. The surface through holes 603 increase the three-dimensional surface area of ​​the heat sink 602, allowing the internal low heat exchange area to participate in heat dissipation. At the same time, the heat exchange efficiency with air is directly related to the contact area between the heat sink 602 and the air. The larger the surface area, the more heat is transferred per unit time. The increased surface area enhances the thermal radiation effect and strengthens the heat dissipation effect.

[0033] Connecting blocks 4 are installed on both sides of the outer shell 3. An opening 5 is provided inside the connecting block 4. A baffle 8 is installed inside the outer shell 3. A positioning structure 7 is installed on the top of the outer shell 3.

[0034] The positioning structure 7 includes a threaded sleeve 702 installed at the top of the outer shell 3, a threaded rod 701 passing through the top of the threaded sleeve 702, external threads being uniformly arranged on the outer side wall of the threaded rod 701, and internal threads being uniformly arranged on the inner side wall of the threaded sleeve 702 that cooperate with the external threads. The threaded rod 701 and the threaded sleeve 702 are threadedly connected.

[0035] A positioning block 703 is installed at the bottom end of the threaded rod 701, and a rotating block 704 is installed at the top end of the threaded rod 701.

[0036] See attached document Figure 1-2 and attached Figure 4 As shown, the wire harness can enter the interior of the housing 3 through the opening 5. The baffle 8 can separate the wire harness. The mounting screw 2 and the base plate 1 form a threaded connection, and the device can be fixed by the mounting screw 2. The threaded sleeve 702 and the threaded rod 701 form a threaded connection, and the rotating block 704 can be gripped to drive the threaded rod 701 to rotate. The rotation of the threaded rod 701 will drive the threaded rod 701 to rise and fall. The rising and falling of the threaded rod 701 can drive the positioning block 703 to rise and fall. The rising and falling of the positioning block 703 can press the wire harness at the bottom end to position the wire harness and prevent the wire harness from falling off. At the same time, the adjacent threaded rods 701 are arranged in an alternating manner, which makes it easier for the rotating block 704 to grip.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
