Technical Field

[0001] The utility model relates to the field of cable connectors, in particular to a cable and connector structure. Background Art

[0002] The existing disclosed digital sensor connector structure basically consists of a connector and a single-layer shielded wire for outputting signals.

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Please refer to the attached Figure 1-4 The cable and connector structure provided by the utility model includes a sensor 1 and a connector 2. The sensor 1 is a well-known technology for those skilled in the art and will not be described in detail. The connector 2 is detachably connected to a sensor cable 3 through a connecting component. A sensor assembly thread 4 is provided at one end of the connector 2. The sensor 1 and the connector 2 are threadedly connected through the sensor assembly thread 4, that is, the user only needs to rotate the connector 2 forward and backward to control the disassembly and assembly between the connector 2 and the sensor 1. A protective component is provided inside the sensor cable 3;

[0021] The connecting component includes a nut 5, a wiring harness hole 6 is opened in the center of the nut 5, and the end surface of the connector 2 away from the sensor assembly thread 4 is threadedly connected to the inner wall of the nut 5, that is, the user only needs to rotate the connector 2 and the nut 5 in the forward and reverse directions to control the disassembly and assembly of the connector 2 and the nut 5. The operation is simple and convenient and not prone to errors. A sensor wire assembly hole 7 is opened in the center of the connector 2, and the sensor wire assembly hole 7 corresponds to the wiring harness hole 6. The sensor cable 3 passes through the sensor wire assembly hole 7 and the wiring harness hole 6 in sequence. A wire clamping ring 8 is fixed at one end of the connector 2 away from the sensor assembly thread 4. When the nut 5 and the connector 2 are tightened, the inner surface of the wire clamping ring 8 abuts against the surface of the sensor cable 3. Specifically, the user can first pass the sensor cable 3 through the sensor wire assembly hole 7 and the wiring harness hole 6, and then tighten the nut 5 on the connector 2 by rotating the nut 5. An inclined section (such as Figure 2 As shown), when the nut 5 and the connector 2 are tightened, the inclined section squeezes the wire clamping ring 8 to deform, thereby squeezing and fixing the sensor cable 3 passing through the sensor wire assembly hole 7 and the harness hole 6, and tightening the sensor cable 3 to ensure the connection strength between the sensor cable 3 and the sensor 1;

[0022] The sensor cable 3 includes a plurality of tinned copper conductors 31, each of which is fixed with a cross-linked polyethylene insulation sleeve 32 on its outer surface, and a filling layer 33 is arranged between the plurality of cross-linked polyethylene insulation sleeves 32. The filling layer 33 is preferably a cotton core, which is used to provide support and protect the internal structure.

[0023] The protection component includes an aluminum foil shielding layer 34, which is fixed on the outer surface of a plurality of cross-linked polyethylene insulation sleeves 32, a braided shielding layer 35 is fixed on the outer surface of the aluminum foil shielding layer 34, and a PVC sheath 36 is fixed on the outer surface of the braided shielding layer 35. Specifically, under the double insulating protective layer of the cross-linked polyethylene insulation sleeve 32 and the PVC sheath 36, the impedance can be effectively reduced, so that the signal strength of the long-distance transmission signal can be guaranteed, and the PVC sheath 36 can well conduct the external charge to avoid the generation of surge, so that it is suitable for various complex use environments;

[0024] The protective component also includes a metal braided layer 37, which is fixed on the outer surface of the PVC sheath 36. The outer surface of the metal braided layer 37 is covered with a transparent TPU sheath 38. Specifically, the metal braided layer 37 can prevent mice from biting the cable and increase the strength of the cable. The transparent TPU sheath 38 can protect the user well and prevent the user from being scratched. The soft connection with the object can also reduce the amount of cable wear.

[0025] The use process of the utility model is as follows: the user can first pass the sensor cable 3 through the sensor wire assembly hole 7 and the harness hole 6, and then tighten the nut 5 on the connector 2 by turning the nut 5. When the nut 5 and the connector 2 are tightened, the wire pressing ring 8 is deformed, so that the sensor cable 3 passing through the sensor wire assembly hole 7 and the harness hole 6 is squeezed and fixed, and tightened to ensure the connection strength between the sensor cable 3 and the sensor 1. Then, the connector 2 is threadedly assembled on the sensor 1 through the sensor assembly thread 4. The operation is simple and convenient, and it is not easy to make mistakes.

[0026] During use, the transparent TPU sheath 38 can protect the user well and prevent the user from being scratched. The soft connection with the object can reduce the wear of the cable. The metal braided layer 37 can prevent the cable from being bitten by mice and increase the strength of the cable. The double insulating protective layer of the cross-linked polyethylene insulating sheath 32 and the PVC sheath 36 can effectively reduce the impedance, so that the signal strength of the long-distance transmission signal can be guaranteed. The PVC sheath 36 can conduct external charges well to avoid surges, so that it is suitable for various complex usage environments.

[0027] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
