[0027] Description PN246648ZGCZHJ

[0028] The separation structure 10 comprises a separation support and a separation electrical connector, the separation support is connected with the rocket shell, and the separation electrical connector is installed on the separation support. The separation support mainly plays a role in supporting the separation electrical connector. The end of the steel cable 20 close to the separation structure 10 is connected with the separation electrical connector.

[0029] In the application, the protection structure 30 is a tubular structure, and the steel cable 20 passes through the tubular structure. By arranging the protection structure 30 into a tubular structure, the steel cable 20 can conveniently pass through the protection structure 30. The tubular structure is uniformly stressed and heated, and can better protect the steel cable 20.

[0030] In the application, the steel cable 20 passes through the axis of the tubular structure. When the steel cable 20 passes through the axis of the tubular structure, the steel cable 20 is at the central position of the protection structure 30. Since the central position of the tubular protection structure 30 is farthest from the outside world, the position can best protect the steel cable 20. It is the best embodiment.

[0031] In the application, the length of the protection structure 30 is less than or equal to the length of the steel cable 20. In order to protect the steel cable 20 as well as possible, the length of the protection structure 30 should be the same as the exposed length of the steel cable 20, but due to environmental factors or other equipment, the actual length of the protection structure 30 needs to be less than the length of the steel cable 20. In order to better protect the steel cable 20, the length of the protection structure 30 should be as same as the length of the steel cable as possible.

[0032] In the application, the protection structure 30 comprises a cylinder 31 and a connecting flange 32. The steel cable 20 passes through the cylinder 31. The connecting flange 32 is arranged at one end of the cylinder 31 close to the steel cable 20 support, and the connecting flange 32 is connected with the steel cable 20 support. And the connecting flange 32 is directly detachably connected with the steel cable 20.

[0033] By arranging the protection structure 30 into two parts, one part is used for protecting the steel cable 20, and the other part is used for connecting with the steel cable 20 support, the installation of the protection structure 30 is facilitated. Meanwhile, since the protection structure 30 is detachably connected with the steel cable 20 support, the protection structure 30 can be conveniently replaced. The protection structure 30 can be replaced according to different slackness of the steel cable 20.

[0034] In the application, the protection structure 30 is made of rigid material. The protection structure 30 made of rigid material can better protect the steel cable 20.

[0035] In the application, the separation structure 10 comprises a separation support and a separation electric connector. The separation support is used for connecting with the rocket shell, and the separation electric connector is arranged on the separation support. The separation support and the steel cable 20 support are parallel to each other.

[0036] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0037] 1. In the process of use, since the protection structure 30 is located outside the steel cable 20 and covers the steel cable 20, the action of engine gas flow can be avoided, so that the separation of the steel cable 20 will not be accidentally tightened to cause the early unlocking of the interstage electric connector and the burning of the separation steel cable 20 by high-temperature gas, and the occurrence of damage to the steel cable 20 is reduced.

[0038] 2. By arranging the protection structure 30 into a tubular structure, the steel cable 20 can conveniently pass through the protection structure 30. And the tubular structure is uniformly stressed and heated, so that the steel cable 20 can be better protected.
