Description

Technical fields:

[0001] This utility model belongs to the field of underwater acoustic signal transmission technology, specifically relating to an electronic cabin cable connector tail clip. Background technology:

[0002] Underwater acoustic signals are small signals, and for stable transmission, the requirements for signal transmission are usually extremely high. The small signals need to be amplified locally or converted into digital signals before they can be transmitted stably. This connector is an important hub connecting the equipment inside and outside the cabin. The power supply and signal transmission of the electronic equipment inside the cabin are provided through this connector. Therefore, it is essential that it can provide a stable and reliable signal.

[0003] The existing connector comes with a tightening nut of about 10mm, such as Figure 2 As shown, without a tail clamp, after the cable is electrically installed, it can only be fixed by heating the shrink tubing. After installation, an external insulation component is required to clamp the cable in the cup-shaped tube. During the cable connection process, it is difficult to align the positioning pins of the connector and socket. Positioning is required by adjusting the cable. After adjustment, the cable will be subjected to corresponding torque and self-weight, which makes the cable easy to desolder and unable to provide a reliable and stable input signal to the equipment in the cabin. Utility model content:

[0004] The technical problem to be solved by this utility model is to provide an electronic cabin cable connector tail clip. The tail clip has a reasonable structural design, which prevents the cable core wires from being desoldered due to stress after the equipment is installed, and facilitates cable installation and disassembly.

[0005] The technical solution of this utility model is to provide an electronic compartment cable connector tail clamp, which acts on a connector for connecting a cable to a cup-shaped tube wall socket. The tail clamp includes a sleeve, an insulating component, an O-ring, an inner retaining ring, a tightening nut, a cable cover, and a clamping plate.

[0006] The sleeve is used to connect the cable cover and the connector, so that the connector and the cable cover become a combination to protect the cable from longitudinal and transverse stresses.

[0007] The tightening nut is used to replace the original connector tightening nut and connects the tail clip and the connector;

[0008] The insulating component is used to fill the tail of the connector to provide better insulation.

[0009] The O-ring is used for sealing between the connector and the sleeve;

[0010] The inner retaining ring is used to connect the connector and the sleeve, and serves to fix the connector and the sleeve.

[0011] The clamping plate is used to fix the cable.

[0012] Preferably, the cable clamping plate clamps the cable using M4 slotted cylindrical head screws.

[0013] Preferably, the outer circumferential surface of the tightening nut has a wrench position.

[0014] Preferably, the cable size is 20mm to 28mm.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention clamps the cable to prevent it from being subjected to torque during connector installation, thus avoiding the cable core from detaching from the solder cup and affecting the overall function of the equipment. It effectively improves the stability and reliability of the equipment, changes the original connector without a tail clip, and solves the problems of existing technology that only relies on heat shrink tubing to prevent dust ingress and rotation, requires an external white insulator to clamp the cable in the cup-shaped tube after installation, and is prone to poor soldering due to stress damage to the contact solder joints during electrical assembly due to the weight of the longitudinal watertight cable. This invention prevents the cable core from detaching due to stress after installation, and facilitates cable installation and disassembly. Attached image description:

[0020] Figure 4 This is a schematic diagram of a wire clamp. Detailed implementation method:

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figure 1 , 3 As shown in Figure 4, the tail clamp of the electronic compartment cable connector of this utility model is used to connect the cable to the connector of the cup-shaped tube wall socket. The connector is used to connect the cable to the cup-shaped tube wall socket. The tail clamp includes a sleeve 1, an insulating component 2, an O-ring 3, an inner retaining ring 4, a tightening nut 5, a cable cover 6, a slotted cylindrical head screw, and a wire clamping plate 8.

[0023] The sleeve 1 is used to connect the cable cover 6 and the connector, so that the connector and the cable cover 6 become a combination to protect the cable from longitudinal and transverse stresses. The cable cover 6 of the present invention adds the sleeve 1 to protect the cable, so that the cable will not be subjected to gravity and torsion during installation, and the cable core will not fall off the solder cup. The structure of the sleeve will not affect the existing electrical installation method, and the installation is convenient without reducing the reliability of the tail.

[0024] The tightening nut 5 is used to replace the original connector tightening nut, making the tail clip and connector a single unit.

[0025] Insulating component 2 is used to fill the connector tail to provide better insulation; its structure is the same as that of the prior art.

[0026] O-ring 3 is used between the connector and sleeve 1 to provide a seal;

[0027] The inner retaining ring 4 is used to fix the connector and the sleeve 1. The connector and the cable cover 6 are locked together by the inner retaining ring 4. After the cable is electrically installed, the inner retaining ring 4 is pushed down to the root of the connector along with the cable cover 6, O-ring 3 and so on. In this embodiment, the cable cover 6 is provided with a retaining ring 61. After the inner retaining ring 4 is aligned with the protrusion of the retaining ring 61 of the cable cover 6, it is locked by turning it clockwise. At this time, the connection between the cable cover 6 and the connector is completed.

[0028] The cable clamp 8 is used to clamp the cable after the front retaining ring 4 is tightened, and then uses M4 slotted cylindrical head screws 7 to fix the cable. In this embodiment, the cable clamp 8 is used to fix the cable, and it is locked by using M4 slotted cylindrical head screws. It is suitable for cable sizes of 20mm to 28mm. The cable cover 6 is about 80mm away from the socket housing after electrical installation, and about 16mm higher than the cup-shaped tube wall to facilitate the electrical installation and locking of the cable clamp 8.

[0029] In one embodiment, the tightening portion of the five nuts has a wrench position to accommodate a wrench.

[0030] This invention connects the cable cover and connector by aligning the L-shaped profile at the connector tail with the retaining ring of the cable cover, and then locking the inner retaining ring by lowering it into the convex groove and turning it clockwise. After connection, the cable clamping plate at the tail is secured to the cable using two slotted cylindrical head screws, and then the nut is tightened. Figure 1 Simply rotate the connector to tighten it.

[0031] The electronic cabin cable connector tail clip of this invention fully demonstrates the unique design of the connector tail clip and is matched with the matching connecting cable of the electronic cabin cup-shaped tube socket. It realizes signal transfer and transmission between the electronic cabin and the interior and exterior, underwater and above-water parts, which is an effective means to solve the current electronic cabin cable transmission problem. The addition of the tail clip design to the connector improves the stability and reliability of the connector, and also fully considers the uniqueness and practicality of the cup-shaped tube. It is an improvement and supplement to the connector connection method.
