Description

Technical Field

[0001] The utility model relates to the technical field of thermocouples, in particular to a multifunctional thermocouple cable connector. Background Art

[0002] The cable connector of a thermocouple is a plug or connector used to connect the measuring end of the thermocouple to the compensation wire or directly to the temperature measuring instrument. This connector not only realizes the electrical connection, but also protects the sealing and mechanical support functions of the thermocouple end and the compensation wire joint.

[0003] Since the tail of the current thermocouple cable connector is mostly a fixed structure, in complex mechanical equipment or piping systems, the straight tail connector will affect the layout of the thermocouple, causing the compensation line to be excessively bent near the connector surface, which may cause the surface of the compensation line to crack. At the same time, the cable connector itself does not have a storage function. After the connector is used, the longer compensation line will appear scattered and difficult to organize, which may easily cause damage to the compensation line. Utility Model Content

[0004] The purpose of the utility model is to provide a multifunctional thermocouple cable connector, which has the advantages of being able to change the connection angle of the compensation wire at the tail of the connector so that the compensation wire will not be excessively bent, and being able to store and fix the compensation wire, thereby solving the problem that the current thermocouple cable connector is easily damaged when used and is inconvenient to store.

[0007] As a preferred multifunctional thermocouple cable connector of the utility model, a connecting bolt is penetrated through the thread at the bottom of the lower connecting shell, and a thread groove for matching with the connecting bolt is opened on the inner wall of the upper connecting shell.

[0008] As a preferred multifunctional thermocouple cable connector of the utility model, a positioning rod is fixed on the surface of the lower connecting shell, and a slot for cooperating with the positioning rod is opened on the surface of the upper connecting shell.

[0009] As a preferred multifunctional thermocouple cable connector of the utility model, a fastening nut is threadedly connected on the surface of the movable bolt, and the fastening nut is a butterfly nut.

[0010] As a preferred multifunctional thermocouple cable connector of the utility model, a second telescopic rod is arranged inside the spring, the bottom of the second telescopic rod is fixedly connected to the top of the clamping plate, and the top of the second telescopic rod is fixedly connected to the bottom of the connecting plate.

[0011] As a preferred embodiment of the multifunctional thermocouple cable connector of the utility model, the clamping plate is made of rubber material, and friction patterns are provided on the surface of the clamping plate.

[0012] As a preferred embodiment of the multifunctional thermocouple cable connector of the utility model, the connecting frame and the guide frame are both made of aluminum alloy.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model sets an adjustment mechanism so that the device can be angle-adjusted and the compensation line can be wound and fixed. The connecting ring can drive the movable bolt to move inside the guide frame. At the same time, the bellows can also be extended, so that the connecting end face of the compensation line can be rotated ninety degrees, thereby avoiding skin damage caused by excessive bending of the compensation line. The bellows can protect the internal core wire of the compensation line, making it easier to arrange and position the connector in a limited space. After the connector is used, the compensation line can be wound around the inner recessed parts of the surfaces of the lower connecting shell and the upper connecting shell. After the winding is completed, the clamping plate and the first telescopic rod are pulled upward, and the connecting plate is rotated so that the clamping plate can be turned over the compensation line, so that the spring can apply elastic force to allow the clamping plate to clamp and fix the compensation line, thereby avoiding the compensation line from being scattered.

After the connector is used, the compensation line 103 can be wrapped around the inner recessed parts of the surfaces of the lower connecting shell 101 and the upper connecting shell 102. After the wrapping is completed, the splint 209 and the first telescopic rod 206 are pulled upward, and the connecting plate 207 is rotated so that the splint 209 can be turned over the compensation line 103, so that the spring 208 can apply elastic force to allow the splint 209 to clamp and fix the compensation line 103, thereby avoiding the compensation line 103 from becoming scattered.
