Adapter for pressure and temperature sensor

Abstract

This invention provides an adapter element for a pressure and temperature sensor, comprising a main connector, a protective sleeve, a first seal, a temperature-sensing contact, and a compression elastic member. The main connector has a first accommodating space inside. The protective sleeve engages with the end of the main connector and forms a second accommodating space inside, with at least two openings in its wall. The first seal is disposed on the inner side of one end of the second accommodating space adjacent to the main connector, and has an inner periphery and an outer periphery. The temperature-sensing contact is disposed in the second accommodating space, with one end passing through and tightly abutting the inner periphery. The compression elastic member is disposed within the second accommodating space, abutting between the temperature-sensing contact and the other end of the second accommodating space, providing elastic restoring force to the temperature-sensing contact upon push-up.

Claims

1. An adapter element for a pressure and temperature sensor, comprising: a main connector having an external thread at one end for locking to an external server rack; the main connector having a first receiving space inside, the inner side of the first receiving space having an internal thread for connecting an external pressure and temperature sensor; a protective sleeve engaging with the end of the main connector, the protective sleeve having a tube wall to form a second receiving space inside, the tube wall having at least two openings for external fluid to flow into the second receiving space; and a first seal having an inner periphery and an outer periphery, disposed on the inner side of the second receiving space adjacent to one end of the main connector. A temperature-sensing contact is disposed on the inner side of the second accommodating space adjacent to one end of the main connector, and the end of the temperature-sensing contact adjacent to the main connector is inserted and tightly abuts the inner periphery of the first seal; and a compression elastic member is disposed in the second accommodating space, one end of which abuts the temperature-sensing contact adjacent to the main connector, and the other end of which abuts the inner side of the second accommodating space away from the main connector, so as to provide an elastic restoring force for the temperature-sensing contact to push in the direction of the main connector.

2. The adapter element for the pressure and temperature sensor as described in claim 1, wherein, The main connector also includes an outer wall, an inner wall and a second seal, with an annular groove formed between the outer wall and the inner wall, and the second seal disposed in the annular groove.

3. The adapter element of the pressure and temperature sensor as described in claim 1 further includes an inner guide bushing having a through hole and located between the main body connector and the protective sleeve for axial connection of the main body connector and the protective sleeve.

4. The adapter element for the pressure and temperature sensor as described in claim 1, wherein, The material of the temperature-sensing contact is copper, copper alloy, aluminum alloy, beryllium copper alloy, stainless steel, or thermally conductive ceramic.

5. The adapter element for the pressure and temperature sensor as described in claim 1, wherein, The openings of the protective sleeve are elongated through grooves that extend parallel to one of the axial directions of the protective sleeve and are arranged at equal intervals around the circumference of the protective sleeve.

6. The adapter element for the pressure and temperature sensor as described in claim 5, wherein, The protective sleeve has a total length L and an outer diameter D, and each of the openings has an opening length Ls and an opening width Ws; wherein the ratio of the opening length Ls to the total length L is between 0.20 and 0.60, and the ratio of the sum of the opening widths Ws to the outer diameter D multiplied by pi is between 0.15 and 0.

45.

7. The adapter element of the pressure and temperature sensor as described in claim 2 further includes a support sealing ring and a stress buffer ring disposed inside the first accommodating space.

8. The adapter element for the pressure and temperature sensor as described in claim 1, wherein, The number of such openings in the pipe wall is four.

9. The adapter element for the pressure and temperature sensor as described in claim 7, wherein, The first seal, the supporting sealing ring, and the stress buffer ring are O-rings made of EPDM rubber or fluorinated rubber.

10. The adapter element for the pressure and temperature sensor as described in claim 2, wherein, The second seal is a gasket made of soft metal or polymer material.
