Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a high temperature resistant silicone rubber cable. Background Art

[0002] As a key medium for transmitting electric energy or signals, cables are basically composed of conductors, insulation layers, shielding layers (depending on the cable type), filling layers, and sheaths. The performance of cables is mainly reflected in three aspects: mechanical properties, electrical properties, and thermal properties. Thermal properties are further divided into heat resistance and heat dissipation, and the two are usually interrelated and synergistic.

[0003] As far as the existing high-temperature resistant cable technology is concerned, the conventional means of achieving high-temperature resistance mainly focuses on the use of high-temperature resistant materials for the sheath or insulation layer. However, this traditional method faces severe development bottlenecks. If you want to further improve the high-temperature resistance of the cable, you can only resort to the use of more expensive materials or devote yourself to the development of new material formulas. However, whether it is to obtain high-priced materials or to carry out research and development of new formulas, it is inevitable to invest huge human, material and financial resources. This undoubtedly brings great obstacles and challenges to the continuous advancement of high-temperature resistant cable technology, and has also become one of the key factors restricting the efficient development of related industries. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a high-temperature resistant silicone rubber cable, including: a plurality of conductors 1; a plurality of accommodating grooves 3 are provided on a cooling body 2, the conductor 1 is located in the accommodating grooves 3, the cooling body 2 also has a first inner cavity 201, the first inner cavity 201 is used to hold a coolant, and the cooling body 2 is a heat-conducting material; the conductor 1 and the cooling body 2 are located in a sheath 4; a filling layer 5 is located between the sheath 4 and the cooling body 2, and between the sheath 4 and the conductor 1.

[0024] In this embodiment, the sheath 4 is made of high temperature resistant material, and the insulating layer of the wire 1 is also made of high temperature resistant material. All the conventional materials used are conventional materials in the prior art, which will not be described in detail here. In order to further improve the high temperature resistance and heat dissipation effects, a cooling body 2 is added inside the sheath 4, and a coolant is added to the first inner cavity 201 of the cooling body 2. The wire 1 is located in the receiving groove 3, and the cooling body 2 is made of heat conductive material. The specific process is: ① When the external environment temperature rises (for example, fire, etc.), the temperature of the sheath 4 will also rise. Although the sheath 4 is high temperature resistant, the sheath 4 cannot insulate heat. The sheath 4 will transfer heat to the wire 1 and the cooling body 2. After the temperature of the wire 1 rises, it will also transfer heat to the cooling body 2. The coolant in the cooling body 2 will absorb heat, which prevents the temperature of the sheath 4 and the wire 1 from rising to a very high temperature, melting or burning, and increases the high temperature resistance of the cable.

[0025] ② If the temperature of wire 1 rises, the heat can be directly transferred to the cooling body 2. The cooling body 2 absorbs the heat, avoiding the spontaneous combustion of wire 1 and the increase of resistance of wire 1 due to high temperature, etc., so that wire 1 can maintain excellent performance for a long time.

[0026] Optionally, the accommodating groove 3 is arc-shaped, and the accommodating groove 3 abuts against the outer wall of the wire 1 .

[0027] In this embodiment, the wire 1 is generally circular, so the receiving groove 3 is arc-shaped, and the wire 1 is in direct contact with the cooling body 2, which can increase the heat conduction efficiency. In addition, the arc-shaped receiving groove 3 is convenient for the wire 1 to enter the receiving groove 3 when cabling.

[0028] Optionally, it also includes: a cooling block 6 is arranged on the cooling body 2 , the cooling block 6 has a second inner cavity 601 , the second inner cavity 601 is communicated with the first inner cavity 201 , and the cooling block 6 abuts against the sheath 4 .

[0029] In this embodiment, in order to further improve the cooling effect of the cooling body 2 on the sheath 4, a cooling block 6 is set on the cooling body 2. The cooling block 6 is in contact with the sheath 4, so that the heat of the sheath 4 can be directly transferred to the coolant, reducing the impact of external high temperature on the wire 1.

[0030] Optionally, there are a plurality of cooling blocks 6 , and the cooling blocks 6 are arranged at intervals from the containing grooves 3 .

[0031] In this embodiment, in order to reduce the interference between the wire 1 and the cooling block 6 during cabling, the cooling block 6 is located in the gap between the two receiving grooves 3, so that the wire 1 does not need to contact the cooling block 6 when entering the receiving groove 3.

[0032] Optionally, the cooling body 2 further has a through hole 202 , the axis of the through hole 202 is parallel to the axis of the wire 1 , and the through hole 202 is used for one of the wires 1 to pass through.

[0033] In this embodiment, in order to better utilize the cooling body 2, a through hole 202 is opened in the middle of the cooling body 2, and one of the wires 1 directly passes through the through hole 202, which reasonably distributes the space inside the sheath 4 and avoids the cable looking very thick from the appearance.

[0034] Optionally, the accommodating groove 3 is spiral-shaped.

[0035] In this embodiment, because the conductors 1 of some cables are laid in a spiral manner, the receiving groove 3 is designed to be in a spiral shape accordingly. The angle and direction of the spiral receiving groove 3 are completely consistent with the situation of laying the conductors 1. During the laying process, the conductors 1 can smoothly enter the receiving groove 3 without any hindrance, thereby adapting to various types of cables.

[0036] Optionally, there are several cooling bodies 2, and the several cooling bodies 2 are arranged along the axial direction of the wire 1; wherein, the first inner cavity 201 of the non-head end and non-end cooling bodies 2 both have an inlet 203 and an outlet, the first inner cavity 201 of the head end cooling body 2 has an outlet, and the first inner cavity 201 of the end cooling body 2 has an inlet 203, and the several cooling bodies 2 are connected end to end in sequence; the cooling body 2 and the cooling block 6 are made of flexible thermally conductive material.

[0037] In this embodiment, taking full account of the possibility that the cable may be bent during use or transportation, the cooling body 2 is designed into multiple parts, which are then connected together to better adapt to the bending of the cable.

[0038] The first inner cavities 201 of the multiple cooling bodies 2 are interconnected. On the one hand, the cabling process can be completed first, and then the coolant can be injected from the first or last cooling body 2, and the coolant can be smoothly filled into the first inner cavities 201 of all cooling bodies 2, thereby ensuring that the entire cooling system can function normally. On the other hand, the coolant can also be injected when in use, thereby reducing the overall weight of the cable and the cooling body 2 during transportation, reducing transportation costs and difficulties.

[0039] At the same time, the cooling body 2 is designed to be divided into multiple sections, and a flexible material is selected (such as some existing sheath 4 materials with high temperature resistance and high thermal conductivity). When the cable is bent, the cooling body 2 can be flexibly deformed, effectively avoiding breakage or damage due to bending, thereby preventing the coolant from flowing out of the cooling body 2, creating good heat dissipation conditions for the stable operation of the cable.

[0040] Optionally, it also includes: a connecting tube 204 is arranged at the outlet; a clamp 205 is arranged on the side of the connecting tube 204 away from the outlet, the clamp 205 is conical, the cross-section of the clamp 205 gradually decreases in the direction away from the outlet, the maximum diameter of the axial cross-section of the clamp 205 is greater than the diameter of the inlet 203, and the connecting tube 204 and the clamp 205 both have a channel 206, and the channel 206 is connected to the first inner cavity 201.

[0041] In this embodiment, the clamp 205 needs to be inserted into the first inner cavity 201 during operation. The clamp 205 has a conical structure so that it can be inserted with force by external force. When the clamp 205 successfully enters, since the diameter of one end of the clamp 205 is larger than the diameter of the inlet 203, the clamp 205 will be firmly stuck, thereby achieving a stable connection effect. Preferably, the length of the connecting tube 204 is set to match the thickness of the inlet 203. With the clamp 205 being stuck and the length of the connecting tube 204 being matched, the two cooling bodies 2 can be directly clamped together tightly to ensure the firmness of the connection between the two.

[0042] Optionally, the diameter of the connecting pipe 204 is equal to or larger than that of the inlet 203 .

[0043] In this embodiment, considering the adverse effects that leakage may have on the operation of the system, the connecting pipe 204 is connected to the inlet 203 by interference fit. This interference fit can form a tight connection structure, greatly increase the sealing of the connection part, effectively fill the possible gaps, and successfully eliminate the risk of liquid leakage.

[0044] Optionally, it also includes: there are a plurality of support blocks 207, which are respectively arranged on both sides of the cooling body 2; the clamping blocks 208 are arranged on the support blocks 207, and the clamping blocks 208 on two adjacent cooling bodies 2 are clamped.

[0045] In this embodiment, in order to strengthen the stability of the connection between the two cooling bodies 2, a clamping block 208 is respectively provided on the connection surface of the two. The mutual clamping of the clamping blocks 208 can effectively prevent the two cooling bodies 2 from moving away from each other when the cable is bent, and the two connecting bodies from being separated during the cabling process. At the same time, it is necessary to ensure that the length of the connecting tube 204 is compatible with the length of the support plate to ensure the coordination and effectiveness of the overall structure, thereby providing more reliable cooling and support guarantees for the stable operation of the cable.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
