Abstract

The invention discloses an oil blocking device for a temperature sensor and a manufacturing method of the oil blocking device. The oil blocking device comprises a wire, the head end, the middle and the tail end of the wire are provided with a first oil blocking section, a second oil blocking section and a third oil blocking section respectively, the first oil blocking section is fixed to a guide pipe in a hexagonal cold clamping mode through a cold clamping machine, and the second oil blocking section and the third oil blocking section are fixed to the guide pipe in a common cold clamping mode; the second oil blocking section is composed of an oil blocking sleeve, a glue pouring layer and a silicone rubber layer, the guide pipe is provided with an exposed section in the second oil blockingsection, and the outer side of the exposed section is coated with the silicone rubber layer. The insulation stability and the sealing performance of the exposed part of the wire are guaranteed through the silicone rubber layer and the glue pouring layer in each oil blocking section, the gap between the oil blocking sleeve and the wire is greatly reduced in a cold clamping mode, the internal sealing performance of the wire is improved, the oil leakage phenomenon is thoroughly eradicated, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the field of temperature measuring instruments, in particular to an oil blocking device used on a temperature sensor and a manufacturing method thereof. Background technique [0002] In industrial production process, temperature is one of the important parameters that need to be measured and controlled. When the existing temperature measuring element measures the temperature of oily substances, it is necessary to immerse the temperature measuring element in the oil or measure the temperature in an oily environment. On-site work has caused a lot of inconvenience and potential safety hazards. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an oil-repelling device for a temperature sensor and its manufacturing method, which is used to solve the problem of oil leakage and potential safety hazards in the prior art. . [0004] In o...
