[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. 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.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the prior art, the signal line connecting the internal and external units is easily loosened when pulled by force, and the loose signal line will cause circuit failure of the electrical box main board. The signal line needs to be pressed, but the motor line and the electric auxiliary heating line cannot be pressed. The existing fixed line structure cannot simultaneously meet the routing requirements of the signal line, the electric auxiliary heating line and the motor line coming out of the electrical box.

[0031] In order to solve the technical problems in the prior art, the utility model is further described in conjunction with the accompanying drawings and embodiments:

[0032] like Figures 1 to 3As shown, a multifunctional wire fixing structure disclosed in this embodiment includes: a wire fixing clamp 1, a wire pressing clamp 2, a first buckle portion 3 and a second buckle portion 4. The wire fixing clamp 1 is used as an integral structural member of the multifunctional wire fixing structure. The middle part of the wire fixing clamp 1 is bent to form a supporting ridge 11; the wire pressing clamp 2 is detachably mounted on the wire fixing clamp 1 to press and fix the signal line 6. A wire pressing channel is formed between the wire pressing clamp 2 and the wire fixing clamp 1, and the wire pressing space can accommodate the signal line 6 to pass in and out; the first buckle portion 3 is used to limit , fix the electric auxiliary heating wire 7, the protrusion is arranged on the wire fixing clamp 1, and a first wire fixing space is formed between the first buckle part 3 and the supporting ridge 11, and the first wire fixing space clamps the electric auxiliary heating wire 7 and is not easy to fall out; the second buckle part 4 is arranged on one side of the wire fixing clamp 1, and the second buckle part 4 is used to limit and fix the motor line 8, and is provided with a positioning member 41, and a second wire fixing space is formed between the positioning member 41 and the fixed carrier of the wire fixing clamp 1, and the second wire fixing space clamps the motor line 8 and is not easy to fall out, and the fixed carrier can be an electrical box 5.

[0033] The multifunctional wire fixing structure of this embodiment is applied, and a wire pressing clamp 2, a first buckle part 3 and a second buckle part 4 are arranged on the wire fixing clamp 1, that is, the signal wire 6 coming out of the electrical box 5 is fixed and pressed by the wire pressing clamp 2 to ensure that it does not loosen, and it is firm and reliable. At the same time, the wire pressing channel formed between the wire pressing clamp 2 and the wire fixing clamp 1 makes the signal wire 6 easy to be pulled off by force, and the first buckle part 3 and the second buckle part 4 ensure that the electric auxiliary heating wire 7 and the motor wire 8 are stuck and not easy to loosen, and at the same time meet the routing requirements of the signal wire 6, the electric auxiliary heating wire 7 and the motor wire 8. Compared with the traditional wire tying fixing method, the operation is simple. Three different lines pass through the multifunctional wire fixing structure, and are routed separately into the electrical box 5 without interfering with each other.

[0034] Furthermore, the upper section of the first buckle portion 3 is bent toward the support ridge 11 to form a clamping portion 311, and a wire passing opening is provided between the clamping portion 311 and the support ridge 11, and the electric auxiliary heating wire 7 enters the first wire fixing space from the wire passing opening to complete position limiting and fixing.

[0035] Furthermore, the first buckle portion 3 is provided with a first limiting member 31 and a second limiting member 32, and the upper sections of the first limiting member 31 and the second limiting member 32 are bent toward the support ridge 11 to form a clamping portion 311, and a first fixed line space is formed between the first limiting member 31, the second limiting member 32 and the clamping portion 311 and the support ridge 11.

[0036] The number of the first limiting member 31 and the second limiting member 32 can be adjusted as needed along the routing direction of the electric auxiliary heating wire 7 , and can be three, four, etc., without specific limitation here.

[0037] Furthermore, an angle is formed between the first buckle portion 3 and the wire clamp 1 .

[0038] Furthermore, a wire entry opening is reserved between the positioning member 41 and the fixed carrier, and the motor wire 8 falls into the second wire fixing space from the wire entry opening to complete position limiting and fixing.

[0039] The above-mentioned wire clamp 1 is installed at the high-voltage line outlet of the electrical box 5. Usually, the high-voltage wires coming out of the electrical box 5 are divided into the following three types: 1. Signal line 6 connecting the internal and external units; 2. Electric auxiliary heat; 3. Motor line 8.

[0040] As a preferred embodiment, the wire clamp 1 is made of plastic material. More preferably, the wire clamp 1 is made of ABS+PC (VO) material. The injection molding material has strong plasticity. Since the wire clamp 1 needs to be routed, it is not suitable to be made of metal material.

[0041] Preferably, the wire clamp 2 is also made of plastic material.

[0042] As a preferred embodiment, the wire clamp 2 is arranged at the left side of the wire fixing clamp 1, the first buckle part 3 is arranged at the middle of the wire fixing clamp 1, and the second buckle part 4 is arranged at the right side of the wire fixing clamp 1. There is a gap between the wire clamp 2, the first buckle part 3, and the second buckle part 4, so that the lines passing through the wire clamp 2, the first buckle part 3, and the second buckle part 4 are routed independently without interfering with each other.

[0043] During installation and use, the wire clamp 2, the first buckle part 3, and the second buckle part 4 are arranged in sequence in the horizontal direction, or in sequence in the vertical direction. In other words, the signal line 6, the electric auxiliary heating line 7, and the motor line 8 are arranged horizontally, or the signal line 6, the electric auxiliary heating line 7, and the motor line 8 are separated and arranged in the vertical direction.

[0044] Furthermore, the multifunctional wire fixing structure is vertically installed on the electrical box 5 , or the multifunctional wire fixing structure is horizontally installed on the electrical box 5 .

[0045] As a preferred embodiment, the wire clamp 1 is provided with a mounting hole 101 and a fastener, and the fastener passes through the mounting hole 101 and is connected to the electrical box 5 or other fixed carrier to fix the wire clamp 1 on the electrical box 5 or other fixed carrier.

[0046] More preferably, the fastener is a screw. Through the threaded connection mode, the wire clamp 1 can be quickly disassembled and installed, which is easy to operate.

[0047] The number and positions of the mounting holes 101 on the wire clamp 1 are adjusted according to actual conditions and are not specifically limited here. The routing paths of the signal wire 6 , the electric auxiliary heating wire 7 and the motor wire 8 are avoided as much as possible.

[0048] As a preferred embodiment, a first anti-slip portion 102 is provided at a position of the wire fixing clamp 1 opposite to the wire pressing clamp 2 , and / or a second anti-slip portion is provided on a side of the wire pressing clamp 2 opposite to the wire fixing clamp 1 .

[0049] The first anti-slip portion 102 is located on the wire pressing channel and between the wire fixing clamp 1 and the wire pressing clamp 2. The first anti-slip portion 102 is usually arranged on the wire fixing clamp 1 to increase the friction force of the signal line 6 in the wire pressing channel, so that the signal line 6 fixed in the wire pressing channel is not easily pulled out by force.

[0050] When the signal line 6 is fixed in the wire pressing channel, if the fixing surface is a plane and the line surface is smooth, it is easy to be pulled out after being subjected to force. Therefore, in order to prevent the signal line 6 from being easily pulled out of the wire pressing channel, a second anti-slip portion can also be provided on the wire pressing clamp 2. The second anti-slip portion is placed on the inner side and contacts the signal line 6 to increase the friction.

[0051] In order to increase the frictional force of the wire pressing clamp 2 and the fixing clamp on the line, the first anti-slip portion 102 and the second anti-slip portion may be provided at the same time.

[0052] More preferably, the first anti-slip portion 102 is a protrusion formed by protrusions on the surface of the wire clamp 1, including regular point protrusions and irregular point protrusions. The shape of the point protrusions can be dots, triangles, diamonds, and can also include raised ribs. The shape of the ribs can be rectangular, wavy, intermittent lines, arcs, etc., which are not listed here one by one.

[0053] Further, the first anti-slip portion has the same structure as the second anti-slip portion.

[0054] As a preferred embodiment, the wire crimping clamp 2 is provided with a fixing part 21 and a connecting part 22. A positioning hole is opened at the position of the wire crimping clamp 2 relative to the wire crimping clamp 2. The connecting part 22 is fixed to the wire fixing clamp 1 by inserting the fixing part into the positioning hole, and the above-mentioned wire crimping channel is formed between the connecting part 22 and the wire fixing clamp 1.

[0055] The shape of the wire pressing channel can be rectangular, circular, semicircular, etc.

[0056] Preferably, a first fixing cap and a second fixing cap are provided at one end of the fixing member 21, the first fixing cap is provided on one side of the connecting member 22, and the second fixing cap is provided on the other side of the connecting member 22, that is, the connecting member 22 is provided between the first fixing cap and the second fixing cap, and the fixing member 21 fixes the connecting member 22 in a limited position on the wire clamp 1, so as to facilitate the adjustment of the height between the connecting member 22 and the wire clamp 1, thereby adjusting the height of the wire pressing channel.

[0057] More preferably, the fixing member 21 is a screw, and a through hole is provided on the connecting member 22. The through hole is connected to the end cap of the screw on one side away from the wire clamp 1, and a nut is provided on the other side of the through hole close to the wire clamp 1. The fixing member 21 is inserted into the through hole and the nut. The depth of the screw screwed into the wire clamp 1 is controlled by limiting the connecting member 22 between the nut and the end cap of the screw, thereby adjusting the size and height of the wire pressing channel, and improving the versatility of the wire pressing clamp 2.

[0058] More preferably, a baffle is provided inside the connector 22 near the wire pressing channel. The shape of the baffle changes specifically according to the shape of the connecting wire. The baffle is used to separate the fixing member 21 / screw from the wire in the wire pressing channel, so as to avoid the fixing member 21 wearing the wire skin during the installation of the fixing member 21 after the wire is placed in the wire pressing clip 2.

[0059] The connector 22 is in a shape similar to the Chinese character "兀". Of course, the connector 22 can also be designed in a shape similar to the Chinese character "几". The lowest end surface of the connector 22 is flush with the plane of the fixing member 21.

[0060] As a preferred embodiment, an angle is formed between the first limiting member 31 and the wire fixing clip 1, an angle is formed between the second limiting member 32 and the wire fixing clip 1, and an angle is also formed between the first limiting member 31 and the second limiting member 32.

[0061] The above angles are specifically adjusted according to the wiring requirements of the wire, and at the same time, the distance between the first limiting member 31 and the second limiting member 32 also needs to be specifically designed according to the wire routing from the electrical box 5. The lengths and widths of the first limiting member 31 and the second limiting member 32 are determined by the wire diameter of the wire passing through, and it is ensured that the wire can be clamped and is not easy to come out.

[0062] More preferably, the first limiting member 31 is composed of a clamping part 311 in the upper section and a limiting part 312 in the lower section. The clamping part 311 is bent relative to the limiting part 312, and the bending direction is the same as the wire routing, so that the first limiting member 31 is in an inverted L shape as a whole. Among them, the limiting part 312 protrudes relative to the wire fixing clip 1, and can be a straight line segment or an arc segment. There is an angle between the limiting part 312 and the wire fixing clip 1.

[0063] More preferably, the structure of the second limiting member 32 is basically the same as the structure of the first limiting member 31. It is also composed of a clamping part 311 in the upper section and a limiting part 312 in the lower section.

[0064] As a preferred embodiment, reinforcing ribs 111 are provided on the support ridge 11, and the reinforcing ribs 111 are arranged opposite to the first buckle part 3. Since the middle part of the wire fixing clip 1 is bent to form the support ridge 11 and the wire fixing clip 1 is made of plastic material, in order to avoid problems such as whitening and fracture of the fixing clip made of plastic material, the reinforcing ribs 111 are designed on the inner side of the support ridge 11, and the protruding direction of the reinforcing ribs 111 faces the first buckle part 3. The reinforcing ribs 111 extend along the bottom edge of the fixing clip to the support ridge 11, thereby improving the overall strength of the wire fixing clip 1.

[0065] As a preferred embodiment, the right side of the fixing clip is bent to form an extension part 12. One end of the extension part 12 is fixedly connected to the support ridge 11, and the other end of the extension part 12 is connected to the positioning member 41.

[0066] Preferably, the supporting ridge 11 and the extending portion 12 are distributed in a stepped manner.

[0067] More preferably, the wire clamp 1, the first buckle portion 3, and the second buckle portion 4 are integrally formed by injection molding.

[0068] More preferably, a mounting hole 101 is provided on the extension portion 12 to serve as a mounting position for the wire clamp 1 to be fixed to the electrical box 5 or other fixed carrier.

[0069] As a preferred embodiment, the bottom of the wire clamp 1 is a planar structure, which is consistent with the fixing surface of the electrical box 5 or other fixed carrier. The bottom surface of the wire clamp 1 is in close contact with the fixing surface to ensure secure fixation; the upper part of the wire clamp 1 is distributed with the wire pressing clamp 2, the first buckle part 3 and the second buckle part 4 in sequence.

[0070] More preferably, the wire passing planes of the wire clamp 2, the first buckle part 3 and the second buckle part 4 are not on the same plane, for example, the wire passing opening of the wire clamp 2 is higher than the wire passing opening of the first buckle part 3, and the wire passing opening of the second buckle part 4 is higher than the wire passing opening of the wire clamp 2. That is, the wire passing of the signal wire 6 fixed on the wire clamp 2 is higher than the electric auxiliary heating wire 7 limited by the first buckle part 3, and the wire passing of the motor wire 8 limited by the second buckle part 4 is higher than the signal wire 6 fixed on the wire clamp 2.

[0071] The main functions of this utility model:

[0072] The multifunctional wire fixing structure installs a wire pressing clamp on the wire fixing clamp to meet the requirements of the signal line passing under pressure. The first buckle part and the second buckle part are also designed on the wire fixing clamp to meet the requirements of the electric auxiliary heating line and the motor line passing without pressure.
