Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter wiring harnesses, in particular to a frequency converter anti-drag signal wiring harness. Background Art

[0002] The surface of the inverter signal cable currently used is generally made of rubber material, and the signal harness will inevitably experience friction and pulling during the laying process. And when the harness passes through a corner during laying, if the pulling force is too large, the harness will be damaged due to excessive friction with the ground or wall.

[0003] Therefore, the traditional signal wiring harness can be improved so that it can avoid the above-mentioned problems. Utility Model Content

[0004] The utility model aims to solve the above problems and proposes an anti-drag signal harness for a frequency converter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The inverter anti-drag signal harness comprises a wire body, an arc block is arranged outside the wire body, a sheath is fixed to the arc block through a connecting block, through grooves are formed between adjacent connecting blocks, and a filling block is slidably connected in the through grooves, and the sheath outside the wire body is fixed to the wire body through a connecting piece.

[0007] Preferably, the connecting member includes a sleeve block sleeved on the linear body, the sleeve block is provided with a sleeve hole, and the sleeve block is also provided with a corresponding hole, the arc block is provided with a screw hole adapted to the corresponding hole, and the corresponding hole and the screw hole are threadedly connected with a screw rod.

[0008] Preferably, the filling block is provided with a through hole, and water falling into the through groove can flow away from the through hole.

[0009] Preferably, a convex block protrudes from the arc block and abuts against the outer wall of the wire body.

[0010] Preferably, a rubber gasket protrudes from the portion where the two sheaths abut against each other outside the wire body.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The present application can fix the sleeve block and the sheath by threadedly connecting the screw rod with the corresponding hole and the screw hole. The sheath is also fixed to the wire body at the same time, thereby protecting the wire body. Therefore, during the dragging process of the wire body, the wire body will not directly rub against external objects and cause wear.

[0013] 2. After the filling block is extended into the through groove, the compression resistance of the sheath can be exerted, and the protective effect of the sliding sleeve on the wire body can be increased. Even if the sheath is squeezed by foreign objects, it can be easily deformed and affect the wire body. Compared with the arc block, the sheath and the connecting block are relatively soft. Therefore, even if the sheath is deformed, the deformation will be transmitted to the connecting block instead of directly to the arc block. Therefore, the arc block can still protect the wire body.

[0019] 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 of 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.

[0020] Embodiment 1:

[0021] The utility model provides a technical solution, please refer to Figure 1-3 :

[0022] The inverter anti-drag signal harness includes a wire body 1, an arc block 2 is provided outside the wire body 1, a sheath 6 is fixed to the arc block 2 through a connecting block 5, and a through groove 7 is provided between adjacent connecting blocks 5, and a filling block 8 is slidably connected in the through groove 7, and the sheath 6 outside the wire body 1 is fixed to it through a connecting piece. A through hole 9 is provided on the filling block 8, and water falling into the through groove 7 can flow away from the through hole 9. A convex block 3 protrudes from the arc block 2 to abut against the outer wall of the wire body 1, and a rubber gasket protrudes from the part where the two sheaths 6 abut outside the wire body 1. The wire body 1 is isolated from the environment by the action of the sheath 6, so even if the wire body 1 rubs against foreign objects during dragging, it will not cause wear of the wire body 1.

[0023] Embodiment 2:

[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the connector includes a sleeve block 10 sleeved on the wire body 1, a sleeve hole 11 is formed on the sleeve block 10, and a corresponding hole 12 is formed on the sleeve block 10, a screw hole 4 adapted to the corresponding hole 12 is formed on the arc block 2, and a screw rod 13 is threadedly connected at the corresponding hole 12 and the screw hole 4. Under the action of the screw rod 13, the sleeve block 10 and the sheath 6 can be fixed as a whole, thereby playing a protective effect on the wire body 1, and preventing the wire body 1 from being damaged by friction with the ground or wall during dragging.

[0025] In summary, the present embodiment provides that two sleeves 10 are sleeved on the wire body 1, and the filling block 8 is extended into the through groove 7. The filling block 8 can increase the pressure resistance of the sheath 6, and the through hole 9 can play a diversion effect to prevent water from accumulating in the through groove 7. Then the two sheaths 6 can cooperate with each other to surround the wire body 1, that is, the wire body 1 fits with the inner wall of the arc block 2. The screw 13 is connected to the corresponding hole 12 and the screw hole 4 by threading, so that the sleeve 10 can be fixed to the sheath 6, and the sheath 6 is also fixed to the wire body 1, which plays a protective effect on the wire body 1.
