Description

Technical Field

[0001] The invention relates to the technical field of thermistors, and in particular to an assembly structure for thermistors. Background Art

[0002] In the field of thermal management of new energy vehicles and their power battery systems, temperature monitoring of many key components is crucial. In order to achieve efficient temperature data collection, NTC (negative temperature coefficient) thermistors are often used as temperature sensors. These sensors are often packaged with ring terminals, which are fixed to the temperature-measured component by bolt tightening to collect temperature. However, in order to ensure that during the assembly process, in order to prevent the NTC terminal from rotating with it during the bolt tightening process, a special terminal anti-rotation structure is usually required, and it is designed in coordination with the temperature-measured component, and the bolt tightening method needs to rely on nuts and matching tightening tools. Therefore, the assembly operation is relatively cumbersome, which increases the operating hours, and also introduces the costs of nuts, terminal anti-rotation structures, and various accessories required during the installation process, etc., and the overall production cost is high. Summary of the invention

[0003] In view of this, the present invention provides an assembly structure for a thermistor to solve or improve the problem that the assembly operation is relatively complicated, the operation time is increased, and the overall production cost is high.

[0004] The present invention provides an assembly structure for a thermistor, comprising a fixing column and a clamping fixing structure; the fixing column is suitable for being fixed on a temperature-measured component; the clamping fixing structure comprises a packaging groove and a connecting groove, and the packaging groove is suitable for installing the thermistor; the connecting groove is arranged adjacent to the packaging groove, and a through hole is provided at the bottom of the connecting groove, and an elastic clamping component is protruded on the groove wall of the connecting groove, and the fixing column passes through the through hole and is clamped with the elastic clamping component.

[0005] Beneficial effects: By setting a packaging groove on the snap-fit ​​fixing structure, the installation and fixation of the thermistor is achieved; a connecting groove is set on the snap-fit ​​fixing structure, and since a through hole is set on the bottom of the connecting groove, and an elastic snap-fit ​​assembly is set on the groove wall of the connecting groove, when the fixing column passes through the through hole, the elastic snap-fit ​​assembly snaps the fixing column to prevent the fixing column from being separated from the snap-fit ​​fixing structure, thereby achieving a stable connection between the snap-fit ​​fixing structure and the temperature-measured component; the present application can complete the installation and fixation of the thermistor and the temperature-measured component through a simple pressing operation. Compared with the traditional threaded connection method of nuts and studs, the problem of synchronous rotation of the thermistor with the studs is avoided, and the installation cost and installation time of the terminal anti-rotation structure and the fixing nut are greatly saved, thereby reducing the overall production and maintenance costs.

[0006] In an optional embodiment, the elastic snap-fit ​​assembly includes one or more spring sheets, and a plurality of the spring sheets are arranged around the connecting groove; one end of the spring sheet is connected to the groove wall of the connecting groove, and the other end of the spring sheet extends to a side away from the bottom of the connecting groove, and along the direction away from the bottom of the connecting groove, the distance between the spring sheet and the bottom of the connecting groove gradually increases.

[0007] Beneficial effect: Through the setting of multiple spring clips, a stable clamping of the fixing column can be achieved; since one end of the spring clip is connected to the groove wall of the connecting groove, and the other end of the spring clip extends to the side away from the groove bottom of the connecting groove, it can be ensured that the fixing column can smoothly pass through the through hole in the axial direction, effectively avoiding the obstruction that may be caused by the spring clip during the insertion of the fixing column; and since the distance between the spring clip and the groove bottom of the connecting groove gradually increases toward the side away from the groove bottom of the connecting groove, an inclined setting of the spring clip is formed, which not only enhances the elastic performance of the spring clip, but also enables the spring clip to fit more tightly and flexibly on the fixing column, thereby achieving reliable elastic clamping of the fixing column.

[0008] In an optional embodiment, a through hole is provided on the groove wall of the connecting groove, and one end of the spring sheet connected to the groove wall of the connecting groove is located below the through hole.

[0009] Beneficial effect: Since a through hole is provided on the groove wall of the connecting groove, and one end of the spring sheet connected to the groove wall of the connecting groove is located below the through hole, the elastic action range of the spring sheet is expanded, and the flexibility and adaptability of its elastic space are enhanced. The spring sheet can be deformed freely within a larger range, thereby more efficiently exerting its elastic clamping and fixing functions, ensuring the stability and reliability of the overall structure.

[0010] In an optional embodiment, the end of the spring sheet away from the bottom of the connecting groove is the connecting end, and when the fixing column and the elastic snap-fit ​​assembly are not snap-fitted, the distance between the connecting end and the axis of the through hole is smaller than the radius of the fixing column.

[0011] Beneficial effect: Since the distance between the connecting end of the spring sheet and the axis of the fixing column is smaller than the radius of the fixing column when the fixing column and the elastic clamping assembly are not clamped, after the fixing column passes through the through hole, the connecting end of the spring sheet can be firmly embedded or clamped on the surface of the fixing column. By utilizing the size difference, effective locking between the spring sheet and the fixing column is achieved, thereby enhancing the stability of the structure and the safety of the connection.

[0012] In an optional embodiment, a protrusion structure is provided on the outer periphery of the fixing column, and one end of the spring sheet away from the bottom of the connecting groove is suitable for engaging with the protrusion structure.

[0013] Beneficial effect: Since a protruding structure is provided on the outer periphery of the fixing column, the end of the spring sheet away from the bottom of the connecting groove can be clamped under the protruding structure, which not only ensures that the spring sheet can fit tightly to the fixing column, but also enhances the clamping and fixing effect of the spring sheet on the fixing column through the physical blocking of the protruding structure, which not only improves the stability of the connection, but also ensures the reliability and durability of the overall structure.

[0014] In an optional embodiment, the protruding structure is a thread arranged on the outer circumference of the fixing column.

[0015] Beneficial effect: By setting the protruding structure as a thread on the outer periphery of the fixed column, the fixed column can adopt standard parts such as studs, which can not only realize the clamping connection between the fixed column and the elastic clamping assembly, but also simplify the manufacturing process of the fixed column, and optimize production efficiency and cost control.

[0016] In an optional embodiment, a thermally conductive pad is further included, abutting between the clamping and fixing structure and the temperature-measured component.

[0017] Beneficial effect: By arranging a thermal pad to abut between the snap-fit ​​fixing structure and the component to be temperature measured, installation errors can be compensated to ensure that the snap-fit ​​fixing structure is in close contact with the surface of the component to be temperature measured; through the efficient heat conduction performance of the thermal pad, heat between the snap-fit ​​fixing structure and the component to be temperature measured can be transferred quickly and evenly, which not only improves the efficiency of the heat conduction path, but also effectively reduces the thermal resistance, thereby ensuring the accuracy and stability of the temperature measurement results.

[0018] In an optional embodiment, the snap-fit ​​fixing structure also includes a first limit member, which is protruding on the side where the thermal pad is located, located between the connecting groove and the packaging groove, and arranged adjacent to the connecting groove, and is suitable for abutting against the side wall of the temperature-measured component.

[0019] Beneficial effect: Through the setting of the first limit piece, during the connection between the fixing column and the connecting groove, the first limit piece will tightly abut against the side wall of the temperature-measured component, effectively limiting the relative position deviation between the snap-fit ​​fixing structure and the temperature-measured component, thereby ensuring the precise alignment and firm connection between the two in the connected state, improving the overall stability of the connection between the temperature-measured component and the snap-fit ​​fixing structure, and further ensuring the reliability and accuracy of data transmission during the temperature measurement process.

[0020] In an optional embodiment, a second limiting member is further provided in the connecting groove, and the second limiting member is protrudingly arranged on the groove wall of the connecting groove and extends along the axial direction of the through hole, and is suitable for slidingly abutting against the fixing column.

[0021] Beneficial effect: Since the second limit piece extends along the axial direction of the through hole, when the fixing column passes through the through hole, the second limit piece can play a guiding and limiting role for the fixing column, ensuring that the fixing column can always move smoothly and accurately along the axial direction of the through hole, which not only improves the stability and accuracy of the clip-on fixing structure and the fixing column during installation, but also effectively avoids the problem of loose connection caused by position offset or angle deviation; through the precise guidance of the second limit piece, the stability of the connection of the clip-on fixing structure and the reliability of the overall performance are ensured.

[0022] In an optional embodiment, it further includes connecting wires, the connecting wires including a first connecting wire and a second connecting wire, one end of the first connecting wire connected to the thermistor is provided with an adapter connector; one end of the second connecting wire is connected to the thermistor, and the other end of the second connecting wire is detachably connected to the adapter connector;

[0023] Beneficial effect: By setting up an adapter connector, it can be ensured that the second connecting line and the first connecting line form a stable and low-impedance electrical path when connected, thereby realizing accurate transmission and efficient collection of temperature measurement signals; at the same time, since the adapter connector and the second connecting line are detachably connected, it is convenient to separate the second connecting line from the adapter connector, so that there is no need to disassemble the entire temperature measurement system, and the thermistor can be directly replaced or repaired, which simplifies the maintenance process, improves work efficiency, and ensures the continuous and stable operation of the temperature measurement system. The use of the adapter connector also enhances the scalability and compatibility of the system, and can realize simultaneous temperature measurement of multiple temperature-measured components, meeting the diverse needs in complex temperature measurement scenarios.

[0024] In an optional implementation, the material of the clamping and fixing structure is a heat conductive material.

[0025] Beneficial effect: By setting the material of the snap-fit ​​fixing structure to a thermally conductive material, it is ensured that the connecting groove connected to the temperature-measured component can effectively and quickly and accurately transfer the temperature of the temperature-measured component to the thermistor installed in the packaging groove, which not only improves the response speed and accuracy of the temperature measurement, but also further enhances the stability and reliability of the entire temperature measurement system.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0037] According to an embodiment of the present invention, an assembly structure for a thermistor is provided, comprising a fixing column 1 and a snap-fit ​​fixing structure 3; the fixing column 1 is suitable for being fixed on a temperature-measured component 2; the snap-fit ​​fixing structure 3 comprises a packaging groove 31 and a connecting groove 32, and the packaging groove 31 is suitable for installing a thermistor 4; the connecting groove 32 is arranged adjacent to the packaging groove 31, and a through hole 321 is provided at the bottom of the connecting groove 32, and an elastic snap-fit ​​component is protruded on the groove wall of the connecting groove 32, and the fixing column 1 passes through the through hole 321 and is snap-fitted with the elastic snap-fit ​​component.

[0038] By setting a packaging groove 31 on the snap-fit ​​fixing structure 3, the installation and fixation of the thermistor 4 is achieved; a connection groove 32 is set on the snap-fit ​​fixing structure 3, and since a through hole 321 is set on the bottom of the connection groove 32, and an elastic snap-fit ​​assembly is set on the groove wall of the connection groove 32, when the fixing column 1 passes through the through hole 321, the elastic snap-fit ​​assembly snaps the fixing column 1 to prevent the fixing column 1 from being separated from the snap-fit ​​fixing structure 3, thereby achieving a stable connection between the snap-fit ​​fixing structure 3 and the temperature-measured component 2; the present application can complete the installation and fixation between the thermistor 4 and the temperature-measured component 2 through a simple pressing operation. Compared with the traditional threaded connection method of nuts and studs, the problem of the thermistor 4 rotating synchronously with the studs is avoided, and the installation cost and installation time of the terminal anti-rotation structure and the fixing nut are greatly saved, thereby reducing the overall production and maintenance costs.

[0039] In one embodiment, the elastic snap-fit ​​assembly includes one or more spring clips 3221, and a plurality of the spring clips 3221 are arranged around the connecting groove 32; one end of the spring clip 3221 is connected to the groove wall of the connecting groove 32, and the other end of the spring clip 3221 extends to a side away from the bottom of the connecting groove 32, and along the direction away from the bottom of the connecting groove 32, the distance between the spring clip 3221 and the bottom of the connecting groove 32 gradually increases.

[0040] By setting multiple spring clips 3221, a stable clamping of the fixing column 1 can be achieved; since one end of the spring clip 3221 is connected to the groove wall of the connecting groove 32, and the other end of the spring clip 3221 extends to the side away from the groove bottom of the connecting groove 32, it can be ensured that the fixing column 1 can smoothly pass through the through hole 321 along the axial direction, effectively avoiding the obstruction that may be caused by the spring clip 3221 during the insertion process of the fixing column 1; and since the distance between the spring clip 3221 and the groove bottom of the connecting groove 32 gradually increases toward the side away from the groove bottom of the connecting groove 32, an inclined setting of the spring clip 3221 is formed, which not only enhances the elastic performance of the spring clip 3221, but also enables the spring clip 3221 to fit more tightly and flexibly on the fixing column 1, thereby achieving reliable elastic clamping of the fixing column 1.

[0041] In a specific implementation, the elastic piece 3221 is formed by punching the groove wall of the connecting groove 32 inwardly.

[0042] In one embodiment, a through hole 324 is disposed on the groove wall of the connecting groove 32 , and one end of the elastic piece 3221 connected to the groove wall of the connecting groove 32 is located below the through hole 324 .

[0043] Since a through hole 324 is provided on the groove wall of the connecting groove 32, and one end of the spring piece 3221 connected to the groove wall of the connecting groove 32 is located below the through hole 324, the elastic action range of the spring piece 3221 is expanded, and the flexibility and adaptability of its elastic space are enhanced. The spring piece 3221 can be deformed freely within a larger range, thereby more efficiently exerting its elastic clamping and fixing functions, ensuring the stability and reliability of the overall structure.

[0044] In one embodiment, the end of the spring piece 3221 away from the bottom of the connecting groove 32 is the connecting end. When the fixing column 1 and the elastic snap-fit ​​assembly are not snapped together, the distance between the connecting end and the axis of the through hole 321 is smaller than the radius of the fixing column 1.

[0045] Because when the fixing column 1 is not clamped with the elastic clamping assembly, the distance between the connecting end of the spring piece 3221 and the axis of the fixing column 1 is smaller than the radius of the fixing column 1, after the fixing column 1 passes through the through hole 321, the connecting end of the spring piece 3221 can be firmly embedded or clamped on the surface of the fixing column 1. By utilizing the size difference, effective locking between the spring piece 3221 and the fixing column 1 is achieved, thereby enhancing the stability of the structure and the safety of the connection.

[0046] In a specific implementation, the through hole 321 is a circular hole, and the diameter of the fixing column 1 is smaller than the diameter of the through hole 321 , thereby ensuring that the fixing column 1 can smoothly pass through the through hole 321 .

[0047] In one embodiment, a protruding structure is disposed on the outer periphery of the fixing column 1 , and one end of the elastic piece 3221 away from the bottom of the connecting groove 32 is suitable for being engaged with the protruding structure.

[0048] Since a protruding structure is provided on the periphery of the fixing column 1, the end of the spring piece 3221 away from the bottom of the connecting groove 32 can be clamped under the protruding structure, which not only ensures that the spring piece 3221 can fit tightly to the fixing column 1, but also enhances the clamping and fixing effect of the spring piece 3221 on the fixing column 1 through the physical blocking of the protruding structure, which not only improves the stability of the connection, but also ensures the reliability and durability of the overall structure.

[0049] In one embodiment, the protruding structure is a thread disposed on the outer circumference of the fixing column 1 .

[0050] By setting the protruding structure as a thread on the outer periphery of the fixing column 1, the fixing column 1 can use standard parts such as studs, which can not only realize the clamping connection between the fixing column 1 and the elastic clamping component, but also simplify the manufacturing process of the fixing column 1 and optimize production efficiency and cost control.

[0051] In another implementation of this embodiment, the protruding structure may also be a bump, or a protruding ring arranged around the outer circumference of the fixing column 1 .

[0052] In a specific embodiment, the height of the fixing column 1 extending out of the through hole 321 is greater than the height of the elastic sheet 3221. Since the height of the fixing column 1 extending out of the through hole 321 is greater than the height of the elastic sheet 3221, when the fixing column 1 passes through the through hole 321 and reaches the predetermined position, the extended portion thereof is sufficient to effectively contact and interfere with the elastic sheet 3221, thereby causing the elastic sheet 3221 to be firmly clamped on the fixing column 1, and the effective clamping between the fixing column 1 and the elastic sheet 3221 is ensured by utilizing the height difference, thereby enhancing the stability and reliability of the connection structure.

[0053] In one embodiment, a thermal pad 5 is further included, abutting between the clamping and fixing structure 3 and the temperature-measured component 2 .

[0054] By arranging the thermal pad 5 to abut between the clamping fixing structure 3 and the temperature-measured component 2, installation errors can be compensated to ensure that the clamping fixing structure 3 is in close contact with the surface of the temperature-measured component 2; through the efficient heat conduction performance of the thermal pad 5, the heat between the clamping fixing structure 3 and the temperature-measured component 2 is quickly and evenly transferred, which not only improves the efficiency of the heat conduction path, but also effectively reduces the thermal resistance, thereby ensuring the accuracy and stability of the temperature measurement results.

[0055] In one embodiment, the snap-fit ​​fixing structure 3 also includes a first limit member 33, which is protruding on the side where the thermal pad 5 is located, between the connecting groove 32 and the packaging groove 31, and adjacent to the connecting groove 32, and is suitable for abutting against the side wall of the temperature-measured component 2.

[0056] By setting the first limit piece 33, during the connection between the fixing column 1 and the connecting groove 32, the first limit piece 33 will tightly abut against the side wall of the temperature-measured component 2, effectively limiting the relative position deviation between the snap-fit ​​fixing structure 3 and the temperature-measured component 2, thereby ensuring the precise alignment and firm connection between the two in the connected state, improving the overall stability of the connection between the temperature-measured component 2 and the snap-fit ​​fixing structure 3, and further ensuring the reliability and accuracy of data transmission during the temperature measurement process.

[0057] In a specific implementation, the connection groove 32 and the packaging groove 31 are connected via a connection plate 34 , and a first limiting member 33 is disposed on the connection plate 34 . In addition, two limiting members are provided, and the two limiting members are spaced apart and disposed on both sides of the connection plate 34 .

[0058] In one embodiment, a second stopper 323 is further disposed in the connection groove 32 . The second stopper 323 is protrudingly disposed on the groove wall of the connection groove 32 and extends along the axial direction of the through hole 321 , and is suitable for slidingly abutting against the fixing column 1 .

[0059] Since the second limit piece 323 extends along the axial direction of the through hole 321, when the fixing column 1 passes through the through hole 321, the second limit piece 323 can play a guiding and limiting role for the fixing column 1, ensuring that the fixing column 1 can always move smoothly and accurately along the axial direction of the through hole 321, which not only improves the stability and accuracy of the installation process of the clip-on fixing structure 3 and the fixing column 1, but also effectively avoids the problem of loose connection caused by position offset or angle deviation; through the precise guidance of the second limit piece 323, the stability of the connection of the clip-on fixing structure 3 and the reliability of the overall performance are ensured.

[0060] In one implementation of the present embodiment, the elastic clamping assembly includes one spring piece 3221, one spring piece 3221 is arranged on one slot wall of the connecting slot 32, and the second stopper 323 is arranged on the other slot wall of the connecting slot 32. In another implementation of the present embodiment, the elastic clamping assembly includes two spring pieces 3221, the two spring pieces 3221 are arranged on two opposite slot walls of the connecting slot 32, and the second stopper 323 is arranged adjacent to both spring pieces 3221; or the two spring pieces 3221 are arranged on two adjacent slot walls of the connecting slot 32, and the second stopper 323 is arranged opposite to one of the spring pieces 3221. In another implementation of the present embodiment, the elastic clamping assembly includes three spring pieces 3221, two spring pieces 3221 are arranged on two opposite slot walls of the connecting slot 32, the second stopper 323 is arranged adjacent to both of the two spring pieces 3221, and is arranged opposite to the remaining spring piece 3221.

[0061] In a specific implementation, two second position-limiting members 323 may be provided, and the two second position-limiting members 323 are spaced apart along the circumference of the fixing column 1 .

[0062] In one embodiment, it also includes a connecting wire 6, which includes a first connecting wire 61 and a second connecting wire 62. The end of the first connecting wire 61 connected to the thermistor 4 is provided with a transfer connector 63; one end of the second connecting wire 62 is connected to the thermistor 4, and the other end of the second connecting wire 62 is detachably connected to the transfer connector 63.

[0063] By setting up the adapter connector 63, it can be ensured that the second connecting line 62 and the first connecting line 61 form a stable and low-impedance electrical path when connected, thereby realizing accurate transmission and efficient collection of temperature measurement signals; at the same time, since the adapter connector 63 and the second connecting line 62 are detachably connected, it is convenient to separate the second connecting line 62 from the adapter connector 63, so that there is no need to disassemble the entire temperature measurement system, and the thermistor 4 can be directly replaced or repaired, which simplifies the maintenance process, improves work efficiency, and ensures the continuous and stable operation of the temperature measurement system. The use of the adapter connector 63 also enhances the scalability and compatibility of the system, and can realize simultaneous temperature measurement of multiple temperature-measured components 2, meeting the diverse needs in complex temperature measurement scenarios.

[0064] In a specific implementation, an installation opening is provided at one end of the packaging groove 31 away from the connecting groove 32 , and the second connecting wire 62 passes through the installation opening and is connected to the thermistor 4 .

[0065] In a specific implementation, when there are multiple temperature-measured components 2, there are also multiple snap-in fixing structures 3 to ensure that each temperature-measured component 2 can be accurately matched with an exclusive snap-in fixing structure 3, and each snap-in fixing structure 3 is installed with a thermistor 4, and each thermistor 4 is correspondingly connected to a second connecting line 62. This one-to-one correspondence not only improves the accuracy of temperature measurement, but also facilitates subsequent maintenance and management; and multiple second connecting lines 62 are all connected to the adapter connector 63 of the first connecting line 61, and multiple second connecting lines 62 are efficiently connected to the first connecting line 61, which not only realizes centralized management and efficient transmission of signals, but also significantly simplifies the wiring complexity of the system and improves the overall aesthetics and reliability.

[0066] In one embodiment, the clamping and fixing structure 3 is made of a heat-conducting material.

[0067] By setting the material of the snap-fit ​​fixing structure 3 to a heat-conductive material, it is ensured that the connecting groove 32 connected to the temperature-measured component 2 can effectively and accurately transfer the temperature of the temperature-measured component 2 to the thermistor 4 installed in the packaging groove 31, which not only improves the response speed and accuracy of the temperature measurement, but also further enhances the stability and reliability of the entire temperature measurement system.

[0068] In a specific implementation, the clamping and fixing structure 3 is formed by stamping and bending of elastic metal.

[0069] Specifically, the clamping and fixing structure 3 can be made of materials such as beryllium bronze with high elasticity, high wear resistance, high thermal conductivity and fatigue resistance.

[0070] In a specific implementation, a stud with a matching size needs to be pre-set on the temperature-measured component 2, and the through hole 321 at the bottom of the snap-fit ​​fixing structure 3 is aligned with the stud and pressed downward, and the three spring pieces 3221 are stretched open during the pressing process. After the snap-fit ​​fixing structure 3 is pressed into place, the spring pieces 3221 are stuck on the threads of the stud, forming a stable fixing effect. The installation process is simple and quick, and the fixing effect is reliable.
