Description

Technical Field

[0001] The utility model belongs to the field of sockets, and in particular relates to a fixing structure and a socket for reliable contact between a temperature sensor and a contact terminal. Background Art

[0002] When measuring the temperature of the terminal in the socket, the traditional method is to open a hole in the outer shell of the terminal, and then insert the temperature sensor into it so that one end of the temperature sensor contacts the end face of the terminal for measurement. However, this method cannot fix the temperature sensor, and the contact between the temperature sensor and the terminal is not firm, which is easy to produce a gap and affect the measurement result. Utility Model Content

[0003] The utility model aims to provide a fixing structure and a socket for reliable contact between a temperature sensor and a contact terminal.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A fixing structure for reliable contact between a temperature sensor and a contact terminal comprises a terminal and a shell wrapped around the terminal, wherein the terminal comprises an upper end portion located within the shell and a lower end portion protruding from the shell, a groove penetrating through the side wall and the bottom wall of the upper end portion is provided at the bottom of the upper end portion, the groove is used to accommodate the temperature sensor, and the bottom of the shell protrudes inwardly to form a protrusion corresponding to the groove, and a hole communicating with the groove is provided on the protrusion.

[0006] Preferably, the diameter of the through hole gradually decreases from the inside of the shell to the outside.

[0007] Preferably, a thread groove is provided on the top surface of the upper end portion, and a through groove communicating with the thread groove is provided on the outer peripheral wall of the upper end portion along its diameter direction.

[0008] Preferably, an annular groove is provided on the outer peripheral wall of the upper end portion, and a sealing ring is provided in the annular groove.

[0009] A socket comprises a base, wherein a connecting plate is integrally formed between two shells, and a card slot corresponding to the connecting plate is provided at the bottom of the base.

[0010] Preferably, a panel surrounding the outer sides of the two shells is arranged on the top surface of the base.

[0011] The beneficial effect of the utility model is that by providing a groove for accommodating the temperature sensor on the terminal, during installation, the terminal will exert a relative force on the temperature sensor, so that the temperature sensor is tightly attached to the terminal, making it difficult for the temperature sensor to loosen, and the measured temperature is closer to the actual temperature.

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] like Figures 1 to 3 As shown, a fixing structure of a temperature sensor and a contact terminal of the utility model for reliable contact comprises a terminal 10 and a shell 16 wrapped around the outside of the terminal 10, wherein the terminal 10 comprises an upper end portion 12 located in the shell 16 and a lower end portion 14 protruding from the shell 16, wherein the cross section of the upper end portion 12 is circular and can be better adapted to the shell 16, wherein at least one side of the lower end portion 14 is a flat surface and is convenient for opening a hole or connecting with other connecting parts, wherein a groove penetrating through the side wall and the bottom wall of the upper end portion 12 is provided at the bottom thereof, wherein the groove is used to accommodate the temperature sensor 18, and the bottom of the shell 16 is provided with a groove penetrating through the side wall and the bottom wall thereof, wherein the groove is used to accommodate the temperature sensor 18, and the bottom of the shell 16 is provided with a groove penetrating through the side wall and the bottom wall thereof, and the groove is used to accommodate the temperature sensor 18, and the bottom of the shell 16 is provided with a groove penetrating through the side wall and the bottom wall thereof, and the groove is used to accommodate the temperature sensor 18, and the bottom of the shell 16 is provided with a groove penetrating through the side wall and the bottom wall thereof, and the groove is used to accommodate the temperature sensor 18, and the bottom of the shell 16 is provided with a groove penetrating through the side wall and the bottom wall of the upper end portion 12, and the groove ... The protrusion 20 protrudes inwardly to form a protrusion 20 corresponding to the groove, and a hole 22 communicating with the groove is opened on the protrusion 20; the groove is used to accommodate the temperature sensor 18, and the temperature sensor 18 and the terminal 10 are installed together in the housing 16, and the protrusion 20 is used to limit the position so that the temperature sensor 18 is between the terminal 10 and the protrusion 20. During installation, the terminal 10 will apply a force to the temperature sensor 18 so that the temperature sensor 18 and the terminal 10 are tightly fitted and not prone to loosening, and the temperature measurement effect is better and more accurate. The through hole 22 is used for the wire of the temperature sensor 18 to pass through.

[0018] The diameter of the through hole 22 gradually decreases from the inside of the housing 16 to the outside; the diameter of the through hole 22 toward the inside of the housing 16 is larger, which can play a guiding role when the wire of the temperature sensor 18 passes through the through hole 22.

[0019] A thread groove 24 is provided on the top surface of the upper end portion 12, and a through groove 26 connected to the thread groove 24 is provided on the outer peripheral wall of the upper end portion 12 along its diameter direction; other components can be connected to the terminal 10 through the cooperation of the bolt groove and the bolt, and a hole is provided at the end of the bolt. After the installation is completed, the hole on the bolt and the through groove 26 will be connected in a straight line. After the connecting rod is inserted therein, the terminal 10 is installed in the housing 16. The connecting rod cannot be separated from the through groove 26, which can prevent the bolt from loosening.

[0020] An annular groove is formed on the outer peripheral wall of the upper end portion 12 , and a sealing ring 28 is disposed in the annular groove; the sealing ring 28 increases the sealing performance between the terminal 10 and the housing 16 .

[0021] A socket includes a base 30 with a connecting plate 32 integrally formed between two shells 16, and a slot corresponding to the connecting plate 32 is provided at the bottom of the base 30; the connecting plate 32 is more accurately installed through the slot, so that the position of the terminal 10 is more accurate, and it is more convenient to fix the base 30 by the connecting plate 32 than by fixing the shell 16 to the base 30.

[0022] A surrounding plate 34 surrounding the outer sides of the two shells 16 is disposed on the top surface of the base 30 .
