Problems solved by technology

[0003] The prior art has the following disadvantages: the existing mineral cable power installation butt joints are susceptible to moisture, and the insulation and filling layer of the cable is composed of mineral magnesium oxide. During cable construction, when the cable end is stripped and the conductor is exposed, it is easy to Chemically react with moisture in the air to generate conductive magnesium oxide. The insulation resistance of the cable is generally 100MΩ, but if the cable head is made for more than 1 hour, the insulation resistance can drop below 10MΩ, or even drop to 0.5MΩ Below, this will inevitably bring electrical hidden dangers in the engineering of cable use, and the construction is difficult. Compared with ordinary cables, the hardness of mineral cables is higher, and the weight is about twice that of ordinary cables. It is difficult to achieve a parallel and tidy effect when laying. In addition, the line is long and there are many joints, so it is difficult to find the fault point, so the construction is more difficult

The inner wall of the second outer shell is provided with the second inner shell. Yes: the left connecting piece is inserted into the inner wall of the right connecting piece, and the outer shell one and the inner shell one are rotated through the movable shaft, so that the outer fastening edge and the inner fastening edge are rotated and connected, so that the left connecting piece and the right connecting piece are merged, with the installation The effect of convenient docking.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing brackets for electronic equipment, in particular to a composite mineral cable. Background technique [0002] Mineral cables are widely used in control installation, equipment connection, and power transmission. They are an indispensable and important transmission medium for industry and civil use. Cables have various specifications and models to meet the needs of different equipment and transmission purposes. [0003] The prior art has the following disadvantages: the existing mineral cable power installation butt joints are susceptible to moisture, and the insulation and filling layer of the cable is composed of mineral magnesium oxide. During cable construction, when the cable end is stripped and the conductor is exposed, it is easy to Chemically react with moisture in the air to generate conductive magnesium oxide. The insulation resistance of the cable is generally 100MΩ, but if the ca...
