[0002] Photovoltaic flexible cable is a common power transmission equipment. A large number of photovoltaic flexible cables are usually installed on construction sites. For the safe use of photovoltaic flexible cables, photovoltaic flexible cables are usually installed at high places. If the photovoltaic flexible cable is suspended in the air for too long, there is a risk of falling, affecting the safety of operations in nearby areas. Therefore, it is necessary to set segmented fixers at fixed length positions of the photovoltaic flexible cable to protect it.
[0003] Existing photovoltaic flexible cable segment fixers usually use a U-shaped metal part with a recessed portion to fix it. The photovoltaic flexible cable is set in the recessed portion, and the U-shaped part is fixed to a steel beam or other fixed position by tightening bolts, thereby providing protection for the photovoltaic flexible cable to prevent it from falling and also preventing it from being pulled by external forces.

In severe cases, it will cause wear on the contact part of the fixture, affecting the service life of the fixture and its protective effect on the cable. In view of this, we propose an extrusion-type segmented fixture. Utility Model Content
