Description
Technical Field
[0001] The utility model belongs to the technical field of cable shielding, and in particular relates to a moving cable shielding structure and a cable assembly. Background Art
[0002] At present, the shielding treatment method of low-frequency cables is carried out according to the general technical requirements of HB 6438 aircraft wiring harness processing. Figure 1 shown.
[0003] For a single cable, first strip the outer sheath and shielding layer of the cable 1 to form a stripping area 3 at the end of the cable 1; then strip the outer sheath at the position of the cable close to the connector to expose the shielding layer, remove the outer sheath at the end of the grounding wire to expose the core of the grounding wire, weld the core of the grounding wire to the exposed shielding layer, select a suitable heat shrink welding tube 2, wrap the connection between the grounding wire and the shielding layer, and lead out the grounding wire. After the grounding wire is led out, it is fixed to the cable by bundling.
[0004] For multiple cables, after stripping the outer sheath and shielding layer of each cable 1, a stripping area 3 is formed at the end of each cable 1; then the outer sheath is stripped at the position of the cable close to the connector to expose the shielding layer, and the outer sheaths are removed from both ends of the jumper wire to expose the core wire, and the core wire at one end of the jumper wire is welded to the exposed shielding layer of one of the cables, and the core wire at the other end is welded to the exposed shielding layer of another cable. According to this method, the exposed shielding layers of multiple cables are connected in series in sequence, and then the outer sheath is removed from the end of the grounding wire, and the core wire of the grounding wire is welded to the exposed shielding layer of one of the cables, so as to realize the series connection of the shielding of multiple shielded cables and the lead-out of the grounding wire 4. When welding the jumper wire and the grounding wire, a solder sleeve can be used. A heat shrink welding tube 2 is set on the outside of the connection position of the jumper wire, the grounding wire and the exposed shielding layer of the cable. After the grounding wire is led out, the jumper wire, the grounding wire and the cable are tied together and fixed.
[0005] For a single or multiple cables, the other end of the grounding wire 4 is crimped to the grounding terminal 5, and the grounding terminal 5 is finally fixed to the screw 7 of the tail accessory 6 to achieve the shielding overlap of the low-frequency cable. Figure 1 shown.
[0006] With the traditional shielding processing method, the shielded lead wire 4 is crimped to the ground terminal 5 and directly connected to the screw 7 of the tail accessory 6. When the low-frequency cable is laid and installed, the low-frequency cable is bent near the connector, resulting in inconsistent stress states of the ground wire 4 and the trunk cable. When the low-frequency cable moves with the equipment on it, there is a risk that the ground wire 4 is stressed alone and breaks at the crimping point of the ground terminal.
[0007] Therefore, there is an urgent need for a technical solution that can overcome the breakage of the grounding wire of the moving cable. Utility Model Content

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0046] An embodiment of a cable assembly of the utility model, as Figures 2 to 3 As shown, it includes a connector 10 and a cable assembly. The connector 10 includes a shell and a tail accessory 6 at the rear end of the shell. The cable assembly includes a trunk cable 1 and a grounding wire 4. The end of the trunk cable 1 is connected to the connector 10. The exposed wire core at the end of the trunk cable is fixed by the tail accessory 6 on the connector. The grounding wire 4 is connected to the tail accessory. The connector 10 is used to be inserted into the onboard equipment. When the onboard equipment moves, the trunk cable 1 is driven to move, which can easily cause the grounding wire of the trunk cable 1 to break at the connection position with the tail accessory. The shielding structure of the utility model can prevent the grounding wire of the cable from breaking at the connection position with the tail accessory while achieving shielding.
[0047] The outer sheath and shielding layer are stripped off at the end of the trunk cable 1 to expose the wire core, which is covered with an insulating sheath on the outside and a conductor on the inside, forming a stripping area 3. The wire core of the cable stripping area 3 passes through the tail fitting 6 and is connected to the connector 10. The tail fitting includes a pair of pressing plates 8, which are connected and fixed by screws 7 on both sides, and the wire core of the trunk cable 1 is crimped between the two pressing plates 8.
[0048] The shielding layer of the trunk cable 1 near the connector is connected to the grounding wire 4. For a single cable, the outer sheath of the trunk cable 1 near the connector is removed to expose the shielding layer. The outer sheath of one end of the grounding wire 4 is removed and welded to the shielding layer of the cable. A heat shrink welding tube 2 is set at the connection position between the grounding wire 4 and the shielding layer of the cable. The grounding wire 4 is led out of the heat shrink welding tube 2 and extends in a direction away from the connector, then bends and turns to extend to the pressure plate 8. The grounding wire 4 is bent and turned after being led out of the heat shrink welding tube 2, so as to leave a margin for the relative movement of the trunk cable and the grounding wire when the moving cable moves, so as to avoid breaking the grounding wire 4. The grounding wire 4 is fixed to the trunk cable 1 by a binding rope to enhance the connection strength between the grounding wire 4 and the trunk cable 1, so that the grounding wire 4 moves with the trunk cable 1, and the tensile strength of the grounding wire 4 is improved.
[0049] For the cable bundle, the outer sheath of each trunk cable 1 near the connector 10 is removed to expose the shielding layer, the outer sheaths at both ends of the jumper wire 12 are removed, the exposed core wire at one end of the jumper wire 12 is welded and connected to the shielding layer of one of the trunk cables 1, and the exposed core wire at the other end is welded and connected to the shielding layer of another cable 1. According to this method, the shielding layers of each trunk cable 1 are connected in series using the jumper wire 12, and then the outer sheath of one end of the grounding wire 4 is removed and welded and connected to the shielding layer of one of the cables, and a heat shrink welding tube 2 is sleeved on the outside of the connection position of the jumper wire 12, the grounding wire 4 and the cable shielding layer. After the jumper wire 12 and the grounding wire 4 are led out from the heat shrink welding tube 2, they extend in a direction away from the connector, then bend and turn, and then the jumper wire 12 is connected to the shielding layer of another cable, the grounding wire 4 extends toward the pressure plate 8, and the jumper wire 12 and the grounding wire 4 are fixed to the cable bundle with a binding rope.
[0050] After the grounding wire 4 extends to the position of the pressing plate 8, it is bent and turned between the two pressing plates 8 to form a U-shaped folded structure 11 of the grounding wire 4, and is crimped between the two pressing plates 8 along with the wire core of the trunk cable 1. After the grounding wire 4 is led out of the pressing plate 8, the other end of the grounding wire 4 is a crimped end crimped with the grounding terminal 5. Specifically, the grounding wire 4 extends forward to between the pressing plates 8, continues to extend toward the front end, so that the grounding wire 4 protrudes from the pressing plate 8, then the grounding wire 4 is bent and extended to the rear end, passes between the pressing plates 8 again, and then the grounding wire 4 passes through the pressing plate 8 and extends to the rear end, so that the grounding wire 4 forms a U-shaped folded structure fixedly matched with the pressing plate 8 11. The two front and rear extensions extending roughly in the front and rear directions in the U-shaped folding structure 11 are clamped between the pressing plates 8. The front and rear extensions are both clamped and fixed by the pressing plates 8. Compared with crimping a grounding wire between the pressing plates, it has a better fixing effect and improves the tensile strength of the grounding wire 4 in the cable; after the grounding wire 4 is fixed between the pressing plates 8, the grounding wire 4 between the heat shrinkable welding tube 2 and the pressing plate 8 is longer than the trunk cable 1, so the grounding wire between the heat shrinkable welding tube 2 and the pressing plate 8 is not easily stressed; the grounding wire 4 is led out from between the pressing plates 8 and extends to the rear end, then bends and extends to the front end, and the other end of the grounding wire is fixed to the grounding terminal 5. The wiring terminal 5 is fixed to the pressing plate 5 by one of the screws 7. Since the grounding wire 4 between the pressing plate 8 and the grounding terminal 5 has a margin, the grounding wire 4 between the pressing plate 8 and the grounding terminal 5 is not stressed when the cable moves. A heat shrink tube 9 is sleeved at the connection position between the ground wire 4 and the ground terminal 5. The heat shrink tube 9 is sleeved on the pre-insulation sleeve 13 at the tail of the ground terminal 5 and the outside of the root of the connection position between the ground wire 4 and the ground terminal 5 to increase the strength of this position.
[0051] The steps of manufacturing a reliable performance moving cable shielding structure proposed by the utility model are as follows:
[0052] Step 1: Connect multiple cables to the connector according to the general technical requirements of HB 6438 aircraft wiring harness processing, remove the outer sheath and shielding layer of the trunk cable 1 near the connector end, and then connect the core of the trunk cable 1 to the connector 10;
[0053] Step 2: Remove the outer sheath of the portion of the cable 1 close to the connector 10 to expose the shielding layer, use the jumper wire 12 to connect the shielding layers of each trunk cable 1 in series in sequence, and after connecting the shielding layer of each cable, extend the jumper wire 12 to the side away from the connector, bend and turn, and then connect it to the shielding layer of the next cable. After the shielding layers of all the cables are connected, use the grounding wire 4 to connect the shielding layer of one of the cables. The grounding wire 4 first extends to the side away from the connector 10, bends and turns, and then extends to the pressure plate of the rear accessory 6 of the connector 10;
[0054] After the ground wire 4, the jumper wire 12 are connected to the shielding layer of the cable, the heat shrinkable welding tube 2 is used to wrap the connection position of the ground wire 4, the jumper wire 12 and the shielding layer of the cable to protect the exposed shielding layer;
[0055] Use a rope to bundle the ground wire 4, the jumper wire 12 and the trunk cable 1, so that the jumper wire 12, the ground wire 4 and the trunk cable 1 are fastened together;
[0056] Step 3: The ground wire 4 extends along the trunk cable 1 to one side of the connector, and the ground wire 4 is bent and turned at the pressure plate position of the tail accessory and fixed between the two pressure plates 8 of the tail accessory 6 along with the core of the cable;
[0057] Step 4: The end of the ground wire extending from the pressing plate 8 is crimped to the ground terminal 5, and the ground terminal 5 is fixed to the screw of the tail accessory;
[0058] Step 5: A heat shrink tube 9 is sleeved outside the crimping area between the pre-insulating sleeve 13 of the grounding terminal 5 and the root of the grounding wire 4 close to the grounding terminal 5 for protection.
[0059] According to the traditional shielding treatment method, when the cable is bent after installation, the grounding wire is subjected to stress alone, and there is a risk of the grounding wire 4 breaking. Through the shielding structure in the utility model, the grounding wire 4 is fixed in the pressure plate 8 of the tail accessory 6 together with the core of the cable bundle. The grounding wire 4 is connected to the grounding terminal 5 after bending and turning under the pressure plate. The grounding terminal 5 is fixed to the screw of the tail accessory 6, so that the grounding wire between the pressure plate 8 and the tail accessory does not move with the movement of the cable, preventing the grounding wire here from being damaged by tension. A heat shrink tube 9 is added to the tail of the grounding terminal 5 to solve the problem that the grounding wire 4 is broken at the root of the grounding terminal 5 when the grounding wire 4 is bent with the cable.
[0060] The moving cable is processed according to the shielding processing method of the utility model, such as Figure 3As shown, the ab segment grounding wire 4 is installed and laid together with the main cable of the moving cable. The ab segment grounding wire moves synchronously with the main cable, and the force during movement is mainly borne by the main cable. The bc segment grounding wire is folded back under the pressure plate 8 of the tail accessory 6. The grounding wire from c to the grounding terminal end will not be subjected to force alone due to the movement of the moving cable. The tension on the moving cable is mainly borne by the main cable of the moving cable. The bc segment grounding wire is folded back under the pressure plate 8 of the tail accessory 6. The pressure plate 8 is crimped with the grounding wire at multiple positions, which can improve the tensile strength of the grounding wire. Therefore, the anti-destructive strength of the grounding wire is improved.
[0061] The grounding wire test comparison was conducted on the moving cables made by the traditional shielding treatment method and the shielding treatment method of the utility model:
[0062] The moving cable assembly made by the traditional grounding wire processing method is the 1# test piece, and the moving cable assembly made by the grounding wire processing method of the utility model is the 2# test piece. One end of the moving cable is fixed on the fixture, and the other end is the cable plug end with a connector. The cable plug end is subjected to a bending test. Through test comparison, the grounding wire 4 of the 1# test piece broke at the tail of the grounding terminal 5 after 400 bends, and the moving cable of the 2# test piece was not damaged after 3000 bends. Through test comparison, it can be seen that the utility model solves the problem of the breaking of the grounding wire of the moving cable.
[0063] In summary, the shielding processing method of the moving cable of the utility model overcomes the disadvantage of the traditional shielding processing causing the grounding wire of the moving cable to be broken, and achieves the intended purpose of the utility model.
[0064] An embodiment of a moving cable shielding structure of the present invention includes the cable assembly and the tail accessory 6 in the above-mentioned cable assembly.
