Description

Technical Field

[0001] This utility model relates to the field of electric vehicle electrical connection technology, and in particular to a temperature sensor fixing structure and connector socket for connectors. Background Technology

[0002] Existing temperature sensor mounting structures for electric vehicle charging sockets typically use a semi-enclosed structure with the temperature sensor encased in a plastic shell. Due to structural and shape limitations of this type of mounting structure, after the temperature sensor is installed, the thermally conductive silicone can only provide radial positioning, not axial restraint. When the plug is axially inserted into the socket, the lack of axial restraint allows the temperature sensor to easily move or shift axially with the insertion and removal of the plug and socket, resulting in a significant difference between the monitored and actual temperatures and a large measurement error. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing temperature sensor fixing structures cannot axially limit the temperature sensor, leading to easy axial movement or misalignment of the temperature sensor and resulting in large temperature measurement errors. This invention provides a temperature sensor fixing structure for connectors and a connector socket.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A temperature sensor mounting structure for a connector includes: a sensor element circuit board, a thermally conductive silicone body, and a mounting base; the thermally conductive silicone body has a first receiving groove, and the sensor element circuit board can be radially embedded in the first receiving groove; the mounting base has a second receiving groove, and the thermally conductive silicone body is embedded in the second receiving groove; the mounting base can be detachably fixed to the connector housing.

[0006] The solution described in this utility model, by setting the sensor as a sensor element circuit board and providing a first receiving groove in conjunction with the thermally conductive silicone body, allows the sensor element circuit board to be radially embedded in the first receiving groove of the thermally conductive silicone body. Furthermore, by setting the thermally conductive silicone body to be embedded in a second receiving groove, the sensor and the thermally conductive silicone body are fixed and limited both axially and radially, preventing radial relative movement between the sensor element circuit board and the thermally conductive silicone body, and also preventing axial or radial movement of the thermally conductive silicone body relative to the fixed base. During the process of connector plug insertion into socket, the temperature sensor will not move axially or deviate, and can be close to the plug or socket terminal, thereby enabling more accurate monitoring of the temperature inside the connector, reducing measurement errors, and improving the accuracy of temperature monitoring by the temperature sensor.

[0007] Preferably, in the temperature sensor fixing structure for connectors described in this utility model, the sensor element circuit board is provided with an axially outwardly protruding first limiting protrusion; the first receiving groove is provided with an axially inwardly recessed first limiting groove; the first limiting protrusion and the first limiting groove are connected by an interference fit.

[0008] As a preferred embodiment of this utility model, by setting a first limiting protrusion and a first limiting groove, and the first limiting protrusion and the first limiting groove being connected by an interference fit, the axial limit of the sensor element circuit board can be further limited, so as to avoid the sensor element circuit board from axially shifting too far during the process of being installed into the first receiving groove, thereby reducing the possibility of relative movement or displacement between the sensor element circuit board and the first receiving groove, further improving the accuracy of the fixed positioning of the temperature sensor, and enhancing the accuracy of temperature monitoring by the temperature sensor.

[0009] Preferably, in the temperature sensor fixing structure for connectors described in this utility model, the thermally conductive silicone body is provided with a third receiving groove; one axial end of the third receiving groove is connected to the first receiving groove, and the other axial end of the third receiving groove is axially through; the opening of the third receiving groove faces the top surface of the thermally conductive silicone body, and is used to accommodate the sensor electrical signal line.

[0010] As a preferred embodiment of this utility model, by providing a third receiving groove, the sensor electrical signal line can be provided with an installation position, reducing the risk of the sensor electrical signal line being folded or tangled, thereby reducing the probability of poor contact of the sensor element circuit board and improving the stability of temperature monitoring; and with the opening of the third receiving groove facing the top surface of the heat-conducting silicone body, it can be pressed into the third receiving groove simultaneously during the radial embedding of the sensor element circuit board into the first receiving groove, making the installation of the temperature sensor fixing structure more convenient and reliable.

[0011] Preferably, in the temperature sensor fixing structure for connectors described in this utility model, the thermally conductive silicone body is a columnar body with a trapezoidal radial cross-section; the first accommodating groove opens to the top surface of the thermally conductive silicone body.

[0012] As a preferred embodiment of this utility model, by setting the thermally conductive silicone body as a columnar body with a trapezoidal radial cross section, the thermally conductive silicone body can be installed axially into the second receiving groove. The bottom surface is the bottom edge of the trapezoid, and the top surface is the top edge of the trapezoid. The first receiving groove is open to the top surface of the thermally conductive silicone body. If the thermally conductive silicone body is subjected to a radial force towards the top surface, the radial locking effect of the bottom surface is more secure, further reducing the probability of displacement or misalignment of the thermally conductive silicone body and improving the firmness of the temperature sensor fixation.

[0013] Preferably, in the temperature sensor fixing structure for connectors described in this utility model, the outer wall of the thermally conductive silicone body is provided with an axially extending first concave arc surface; the inner wall of the second receiving groove is provided with an inwardly convex first arc surface; the first convex arc surface and the first concave arc surface are matched in shape, thereby providing axial guidance for the thermally conductive silicone body, and can be interference-fitted with the first concave arc surface.

[0014] As a preferred embodiment of this utility model, by setting a first concave arc surface and a first convex arc surface, the first concave arc surface and the first convex arc surface can be connected by an interference fit. After the thermally conductive silicone body is installed and embedded in the second receiving groove, the first concave arc surface and the first convex arc surface cooperate with each other to restrict the radial rotation of the thermally conductive silicone body, further enhancing the limiting and fixing effect on the thermally conductive silicone body. Furthermore, by setting the first concave arc surface to extend axially, it can provide axial guidance for the thermally conductive silicone body, reducing the deformation or installation resistance of the installed thermally conductive silicone body, improving the assembly quality, and enhancing the adaptability of the structure installation.

[0015] Preferably, in the temperature sensor fixing structure for connectors described in this utility model, the bottom surface of the thermally conductive silicone body is provided with an axially extending second concave arc surface; the bottom surface of the second receiving groove is provided with an inwardly convex second arc surface; the second convex arc surface provides axial guidance for the thermally conductive silicone body and can be connected with the second concave arc surface in a concave-convex fit.

[0016] As a preferred embodiment of this utility model, by providing a concave-convex connection between the second concave arc surface and the second convex arc surface, the lateral displacement of the thermally conductive silicone body can be restricted, further enhancing the limiting and fixing effect on the thermally conductive silicone body, and providing axial guidance for the thermally conductive silicone body, reducing the deformation or installation resistance of the installed thermally conductive silicone body, improving the assembly quality, and enhancing the adaptability of the structure for installation.

[0017] To achieve the objectives of this invention, the present invention also provides a connector socket, which includes not only the temperature sensor fixing structure described above, but also: a housing, a terminal assembly, a temperature sensor fixing structure, a resistor, a sealing body, a DC terminal, and a tail cover; the DC terminal is fixedly connected to the terminal assembly; the terminal assembly, the temperature sensor fixing structure, the resistor, and the sealing body are sequentially fitted into the housing along the axial direction; the tail cover is fitted onto the housing.

[0018] The connector socket of this invention, by setting the temperature sensor fixing structure, can limit and fix the temperature sensor axially and radially, so that the temperature sensor is not easily displaced or misaligned. The terminal assembly, temperature sensor fixing structure, resistor and sealing body, and the positions of the terminal assembly and temperature sensor fixing structure are all positioned and sequentially fitted into the housing axially. During the installation process, only axial fitting force exists and will not affect the position of the temperature sensor fixing structure. This enhances the assembly firmness of the connector socket, reduces the mechanical installation error and misalignment possibility of each component, and improves the stability of the connector socket performance.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] The sensor element circuit board can be radially embedded in the first receiving groove of the thermally conductive silicone body, and then the thermally conductive silicone body is embedded in the second receiving groove. The sensor and the thermally conductive silicone body are fixed and limited in both the axial and radial directions, which prevents the sensor element circuit board and the thermally conductive silicone body from moving radially relative to each other, and also prevents the thermally conductive silicone body from moving axially or radially relative to the fixed seat. During the process of connector plug and socket insertion, the thermally conductive silicone body and terminal assembly form an interference fit, which makes the fit tighter and allows for more intuitive monitoring of the temperature rise of the terminal, thereby improving the accuracy and precision of monitoring.
