Description

Technical Field

[0001] The utility model relates to the technical field of equipment wire harnesses, and specifically relates to a wall-penetrating potting-sealed wire harness. Background Art

[0002] For wall-penetrating wire harnesses, the traditional method to achieve sealing is to install a gland on the housing, and the wire harness passes through the middle of the gland. However, the newly added gland not only increases the weight of the equipment, but also has restrictions on the plug size. If the plug size is too large, the gland cannot seal the wire harness.

[0003] The wire cores coming out of the injection-molded plug usually wind together. Since the wires are in close contact with each other and the gap between the wires is small, after potting, the glue cannot well fill the gap, allowing air or water to flow through the gap between the wires into the equipment interior, failing to achieve the sealing effect. Content of the Utility Model

[0004] The utility model aims to provide a wall-penetrating potting-sealed wire harness to solve the problem that after potting, the glue cannot well fill the gap, allowing air or water to flow through the gap between the wires into the equipment interior.

[0005] To achieve the above object, the basic scheme of the utility model is as follows: A wall-penetrating potting-sealed wire harness includes an injection-molded plug, a wire splitting ring, a sheathed cable, and an external interface. The wire splitting ring is provided with a plurality of wire splitting holes. One end of the sheathed cable is connected to the injection-molded plug, and the other end of the sheathed cable is connected to the external interface. The injection-molded plug is detachably connected to the mounting hole of the equipment housing.

[0006] Further, an anti-leakage glue shoulder is provided at the end of the injection-molded plug close to the sheathed cable, and the anti-leakage glue shoulder is in interference fit with the mounting hole of the equipment housing.

[0007] Further, a wedge-shaped bearing plate is provided at the end of the injection-molded plug, and the wedge-shaped bearing plate is matched with a wedge-shaped baffle in the mounting hole of the equipment housing.

[0008] Further, one end of the sheathed cable is bonded inside the injection-molded plug.

[0009] The beneficial effects of this scheme: The wire harness to be installed is divided into single wires and passes through the wire splitting holes on the wire splitting ring. One end of the wire harness is connected to the plug, and the other end of the wire harness is connected to the external interface. The plug is inserted into the socket on the equipment PCBA assembly. The injection-molded plug is connected to the mounting hole of the equipment housing, and the wire splitting ring is placed inside the injection-molded plug. Finally, potting sealant is applied to seal the injection-molded plug and the wire splitting ring with the sealant. The wire splitting ring divides the wire harness into individual single wires. When potting, the gaps between the wires are filled, preventing air or water from reaching the equipment interior through the gaps between the wires from the external interface end, achieving the purpose of sealing, and solving the problem that after potting, the glue cannot well fill the gap, allowing air or water to flow through the gap between the wires into the equipment interior.

[0017] Embodiment

[0018] Basically as shown in the attached Figure 1 figures: A wall-penetrating potting-sealed wire harness includes an injection molding plug 30, a wire splitting ring 20, a sheathed cable 40, and an external interface. As shown in the combination of Figure 2 figures, the wire splitting ring 20 is provided with a plurality of wire splitting holes 21. One end of the sheathed cable 40 is connected to the injection molding plug 30, and the other end of the sheathed cable 40 is connected to the external interface. As shown in the combination of Figure 3 、 Figure 4 figures, the end of the injection molding plug 30 close to the sheathed cable is provided with a glue leakage prevention shoulder 32. The equipment housing 80 is provided with an installation hole 81, and two wedge-shaped baffles 82 are arranged in the installation hole 81. The glue leakage prevention shoulder 32 is in interference fit with the installation hole 81 of the equipment housing 80. The end of the injection molding plug 30 is provided with a wedge-shaped bearing plate 31, and the wedge-shaped bearing plate 31 is matched with the wedge-shaped baffle 82 in the installation hole 81 of the equipment housing 80.

[0019] The specific implementation process is as follows: The wire harness to be installed is divided into single wires and passed through the wire dividing holes 21 on the wire dividing ring 20. One end of the wire harness is connected to the plug 10, and the other end is connected to the external interface. Combining Figure 5 As shown, first pass the plug 10 and the wire dividing ring 20 through the mounting hole 81 of the device housing 80. The plug 10 is inserted into the socket 71 on the device PCBA assembly 70, and then the injection plug 30 is installed. At this time, the anti-leakage glue shoulder 32 forms an interference fit with the mounting hole 81. Then rotate the injection plug 30 by 90 degrees. During the rotation process, the wedge-shaped bearing plate 31 forms a tight fit with the wedge-shaped baffle 82 to achieve the purpose of locking the injection plug 30. Then place the wire dividing ring 20 inside the injection plug 30 and finally pour the sealing glue 60 to seal the injection plug 30 and the wire dividing ring 20 with the sealing glue 60. The wire dividing ring 20 divides the wire harness into individual single wires. When pouring the glue, the gaps between the wires are filled to prevent air or water from reaching the inside of the device through the gaps between the wires at the external interface end, achieving the purpose of sealing.
