[0025] It should be noted that in order to facilitate intuitive display of the proposed connector, the present invention uses Figure 1-Figure 3 To indicate its general shape and appearance, however, in the actual production process, the appearance or shape can be modified according to actual needs. Therefore, the shape and appearance of the product in the drawings of the utility model do not limit the connector.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 3 As shown, a continuous operation underwater connector for a seabed observation network comprises a first connector 1 and a second connector 2 sealed and plugged with the first connector 1, wherein: a receiving groove 3 is provided at the end of the first connector 1, and two clamps 4 for being inserted into the end of the second connector 2 are movably arranged inside the receiving groove 3, and a limit zone of adjustable size is formed between the two clamps 4, and a driving member is provided on the first connector 1, and the driving member is used to drive the two clamps 4 to move closer or farther; when cables are arranged inside the first connector 1 and the second connector 2, the driving member can be used to drive the two clamps 4 to move closer to each other until the two clamps 4 clamp the cables in a limited position, and at this time, the state of the cables placed inside the first connector 1 and the second connector 2 is stable, and can be used in designated places, such as underwater.

[0028] Specifically, the end of the second connector 2 is provided with a groove 5 for accommodating one end of the two clamps 4. When the ends of the two clamps 4 move in a similar manner, the angle between the extension lines of the two clamps 4 is arranged at an acute angle, so that the shape of the limiting area formed between the two clamps 4 can be changed. Furthermore, two pins 6 are movably installed at the end of the first connector 1. The two clamps 4 are provided with extension slots 7 along their lengths, and one end of the two pins 6 is movably connected to the two extension slots 7.

The two threaded sections are threadedly sleeved with moving blocks 9. The two clamps 4 are movably hinged to one of the moving blocks 9.

[0029] like Figure 2As shown, in this state, the bidirectional threaded rod 8 is driven to rotate. Under the limiting effect of the extended slot hole 7 on the clamping plate 4 and the moving block 9, the rotation of the bidirectional threaded rod 8 can drive the moving block 9 to move upward or downward. At the same time, since the pin shaft 6 is movably connected to the extended slot hole 7, the upward or downward movement of the moving block 9 can drive the clamping plate 4 to rotate, and the overall shape of the limiting area formed between the two clamping plates 4 will change, which can realize the limiting clamping of different types of cables and has a wide range of uses.

[0030] In order to guide and limit the cable, a guide plate 10 may be fixedly provided at one end of the two clamping plates 4 located in the groove 5 , and the guide plate 10 is arranged along the length direction of the clamping plates 4 .

[0031] Embodiment 2:

Preferably, the elastic member 12 is provided as a reset spring. In the process of limiting and clamping the cable by using the two clamps 4, since one end of the connecting rod 11 extends into the inside of the limiting area, the end of the connecting rod 11 can first perform a preliminary resistance and limit on the cable, and then under the continued rotation of the two clamps 4, the cable can be completely clamped and limited, and the limiting protection effect is good. At the same time, in order to prevent the connecting rod 11 from damaging the cable when it is in conflict with the cable, a rubber block 13 can be fixedly provided at one end of the two connecting rods 11 close to each other.

[0033] Embodiment three:

[0034] The difference between this embodiment and any of the above embodiments is that, in order to achieve a sealed connection between the ends of the first connector 1 and the second connector 2, a sealing ring 14 can be detachably provided at the end of the second connector 2, and the size of the sealing ring 14 is smaller than the size of the end of the first connector 1, so that after the first connector 1 and the second connector 2 are sealed and plugged in, the sealing ring 14 is pressed between the ends of the first connector 1 and the second connector 2.

[0035] Embodiment 4:

[0036] The difference between this embodiment and any of the above embodiments is that, in order to ensure the sealing between the bidirectional threaded rod 8 and the first connector 1, a sealing gasket can be provided at the connection between the bidirectional threaded rod 8 and the first connector 1. At the same time, the connection between the first connector 1 and the second connector 2 can be stabilized, and a matching buckle 15 can be provided at the end of the first connector 1 and the end of the second connector 2. It should be noted that in this embodiment, a sealing gasket is provided to achieve a sealed connection between the first connector 1 and the second connector 2. In actual use, it is not limited to providing such a sealing member, and conventional technical means in the prior art can also be used to replace it. In order to avoid cumbersome writing, this article will not repeat it here.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. 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 an indirect connection 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.

[0038] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
