[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0013] Embodiment 1: A rotatable sealing elbow tail clamp, such as Figure 1-Figure 5 As shown, it includes a cable, a wire sheath, an elbow, an adapter, a clamping nut cap, a conical rubber sleeve, an elbow sealing ring, a shaft sleeve, a connector sealing ring, an electrical connector plug, a wire core, an elbow limiting boss and an adapter limiting platform. The cable passes through the wire sheath, the wire sheath is sleeved on the elbow, the wire sheath is in contact with one side of the elbow, both sides of the elbow are provided with threads, one side of the elbow is connected with a clamping nut cap through threads, the clamping nut cap is fixedly connected to the wire sheath, a conical rubber sleeve is placed on one side of the elbow, and the other side of the conical rubber sleeve is in contact with the clamping nut cap, and the cable will pass through the conical A rubber sleeve, a shaft sleeve is connected to the other side of the elbow through a thread, an adapter is fitted on the upper part of the shaft sleeve through a gap, an elbow sealing ring is arranged between the adapter and the elbow, a thread is arranged on the inner side of the shaft sleeve, an electric connector plug is connected to the inner side of the shaft sleeve through a thread, the electric connector plug contacts the shaft sleeve, a connector sealing ring is arranged between the electric connector plug and the adapter, a wire core is arranged on the side where the cable extends into the elbow, the wire core passes through the shaft sleeve, an elbow limiting boss is welded on the other side of the elbow, a transfer limiting platform is connected to the adapter through rivets, and the transfer limiting platform will contact the elbow limiting boss.

[0014] In the utility model, the cable is inserted into the elbow, and the material of the conical rubber sleeve is silicone rubber, which ensures its high and low temperature resistance and sealing properties. The compression nut cap and the elbow are connected by threads to tighten the conical rubber sleeve between the cable and the elbow, so that the inner and outer walls of the conical rubber sleeve are deformed. The sealing performance between the cable and one side of the elbow is ensured by the compression of the inner and outer walls of the conical rubber sleeve. The compression of the conical rubber sleeve can be controlled to meet different levels of sealing requirements.

[0015] The wire sheath is also made of silicone rubber. It passes through the cable and is wrapped around the compression nut cap. It can seal and fix the cable to a certain extent, while ensuring that the cable will not swing too much and cause the cable to break.

[0016] The shaft sleeve and the other side of the elbow are connected by threads to tighten the adapter and the elbow sealing ring between the two. The elbow sealing ring is made of silicone rubber, and a certain deformation is formed between the adapter and the elbow to ensure the sealing of the connection between the adapter and the elbow. Based on the same principle, the electric connector plug and the adapter are connected by threads to tighten the connector sealing ring between the two, and the compression deformation of the connector sealing ring is used to ensure the sealing between the electric connector plug and the adapter. The whole design ensures the sealing of the wire core and ensures that it can meet the welding requirements of rain or water immersion.

[0017] The sleeve and the elbow are connected by threads, and the adapter is inserted into the optical axis of the sleeve. The optical axis of the sleeve and the adapter are clearance-matched to ensure that the adapter and the sleeve can rotate relative to each other. This will also allow the elbow and the adapter to rotate relative to each other, so that the outlet direction of the elbow can be rotated arbitrarily. In order to ensure that the internal wire core does not break due to multiple rotations, an elbow limiting boss is designed on the elbow, and an adapter limiting platform is also designed on the adapter. When the elbow and the adapter rotate relative to each other, the elbow limiting boss and the adapter limiting platform will limit each other, thus ensuring as much as possible that the elbow and the adapter will not rotate multiple times and cause the wire core to break. The rotation gap between the adapter and the sleeve is designed inside the elbow sealing ring, which will not affect the internal sealing performance.

[0018] The utility model utilizes a combination of deformation seals of multiple sealing rings to ensure the sealing performance of the elbow tail clamp, and at the same time utilizes the clearance fit between the shaft sleeve and the adapter to realize the variability of the outlet direction of the elbow tail clamp, and utilizes a limiting boss to limit the multi-turn rotation of the elbow tail clamp to protect the cable from breaking.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
