[0082] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0083] According to a first aspect of this application, this application provides a connector 1, referring to... Figure 1 , Figure 2 and Figure 6 It includes: a temperature sensing component 10 and a connection terminal 310; the connection terminal 310 is used to transmit current, and the temperature sensing component 10 is used to detect the temperature of the connection terminal.
[0084] In some embodiments of this application, reference is made to Figures 6 to 8A The temperature sensing assembly 10 includes a temperature sensor 210 and a mounting component 100. The mounting component 100 is used to mount the temperature sensor 210 to the connection terminal 310. It is understood that the mounting component 100 of this application is not only used to mount the temperature sensor 210, but also to transfer heat between the connection terminal 310 and the temperature sensor 210.
[0085] Mounting component 100 includes: device heat transfer part 120 and terminal heat transfer part 110.
[0086] The device heat transfer section 120 is coupled to the temperature sensor 210 for heat transfer; the terminal heat transfer section 110 is coupled to the connection terminal 310 for heat transfer, so that the heat from the connection terminal 310 can be transferred sequentially to the temperature sensor 210 via the terminal heat transfer section 110 and the device heat transfer section 120. The terminal heat transfer section 110 surrounds the surface of the connection terminal 310.
[0087] By using the above technical solution, the temperature sensor 210 is installed to the connection terminal 310 through the mounting component 100, and the heat transfer part of the terminal surrounds the surface of the connection terminal, thereby increasing the area of the connection terminal 310 that the temperature sensor 210 can detect, thereby improving the measurement accuracy.
[0088] Meanwhile, by setting the terminal heat transfer section 110 and the device heat transfer section 120, the temperatures of different areas of the connecting terminal 310 can be fully mixed at the terminal heat transfer section 110 and then transferred to the temperature sensor 210 through the device heat transfer section 120. As a result, the temperature detected by the temperature sensor 210 can better represent the overall temperature of the connecting terminal 310 and has higher accuracy.
[0089] In some specific embodiments, the terminal heat transfer portion 110 extends from at least a first position to a second position, thereby surrounding the connecting terminal 310.
[0090] It should be noted that "bent extension" can be understood as the extension trajectory from the first position to the second position being at least one arc or multiple straight segments, or a combination of arc and straight segments. In this way, the terminal heat transfer part 110 can be adapted to different areas of the connecting terminal 310, forming an enclosure around the connecting terminal 310, thereby having a larger heat transfer area between the terminal heat transfer part 110 and the connecting terminal 310.
[0091] In some specific embodiments, the terminal heat transfer portion 110 extends from a first position to a second position, curving around a center line C1. It should be noted that the center line C1 is a defined virtual axis. On a projection plane perpendicular to the center line C1, the projected outline of the terminal heat transfer portion 110 is set around the projection point of the center line C1, wherein the projection point of the first position and the projection point of the second position may coincide or have a gap.
[0092] In some embodiments of this application, reference is made to Figures 6 to 8A The terminal heat transfer section 110 includes a terminal heat transfer surface 111. The terminal heat transfer surface 111 provides an interface for heat transfer with the connecting terminal 310. It should be noted that, in this application, the interface refers to the boundary area where two objects are in direct contact or exchange heat through a medium. By providing the terminal heat transfer surface 111, heat can be effectively transferred from the connecting terminal 310 to the mounting member 100.
[0093] It can be understood that the terminal heat transfer surface 111 cooperates with the connecting terminal 310 to achieve heat transfer. The terminal heat transfer surface 111 can be the surface of the terminal heat transfer part 110 facing the connecting terminal 310, that is, the solid part of the terminal heat transfer part 110 is located on the side of the terminal heat transfer surface 111 away from the connecting terminal 310.
[0094] Specifically, the terminal heat transfer surface 111 can directly contact the connecting terminal 310 for heat transfer, or other heat-conducting materials can be provided between the terminal heat transfer surface 111 and the connecting terminal 310 for indirect heat transfer.
[0095] In some embodiments of this application, reference is made to Figures 6 to 8A The terminal heat transfer surface 111 includes a main terminal heat transfer surface 111a. The main terminal heat transfer surface 111a is used to provide an interface for heat transfer with the connected terminal 310 along the main heat transfer direction.
[0096] It can be understood that the main terminal heat transfer surface 111a can be the surface in the terminal heat transfer section 110 that receives the most heat from the connecting terminal 310; in other words, the main terminal heat transfer surface 111a can also be the surface with the largest area in the terminal heat transfer surface 111. Correspondingly, the main heat transfer direction can be understood as the main heat transfer direction between the connecting terminal 310 and the terminal heat transfer section 110.
[0097] In some specific implementations, the main heat transfer direction can be set parallel to the above center line C1, and the main terminal heat transfer surface 111a surrounds the surface of the connecting terminal 310 around the center line C1.
[0098] In some embodiments of this application, the heat transfer surface 111a of the main terminal is configured as a curved surface to conform to the surface of the connecting terminal. This configuration reduces localized heat concentration at partial contact interfaces, improves the uniformity of the heat transfer path, and the curved surface enables closer contact, reducing thermal resistance and thus improving overall heat transfer efficiency.
[0099] To further increase the heat transfer area between the main terminal heat transfer surface 111a and the connecting terminal 310, in some embodiments of this application, the main terminal heat transfer surface 111a is constructed as a closed curved surface. It can be understood that the main terminal heat transfer surface 111a is continuously arranged around the center line C1, that is, the main terminal heat transfer surface 111a has no edges or openings in the direction surrounding the center line C1.
[0100] In some specific embodiments, there is a uniform gap or complete contact fit between the closed curved surface and the surface surrounding the connecting terminal 310.
[0101] To further improve uniform heat transfer, in some embodiments of this application, reference is made to Figures 6 to 8A The main terminal heat transfer surface 111a is constructed as a cylindrical surface. It can be understood that the axis of this cylindrical surface coincides with the center line C1. Furthermore, by designing the main terminal heat transfer surface 111a as a cylindrical surface, it is beneficial to ensure full contact between the main terminal heat transfer surface 111a and the connecting terminal 310, as well as the assembly of the terminal heat transfer part 110 and the connecting terminal 310.
[0102] For ease of explanation, unless otherwise specified, the terms axial, circumferential, and radial refer to the axial, circumferential, and radial directions with the centerline as the reference axis.
[0103] In some embodiments of this application, reference is made to Figure 6 and Figure 12The connecting terminal 310 includes a heat transfer mounting section 311. The heat transfer mounting section 311 is used for heat transfer with the heat transfer surface 111a of the main terminal; wherein the heat transfer surface 111a of the main terminal surrounds the outside of the heat transfer mounting section 311. By providing the heat transfer mounting section 311, not only heat transfer with the mounting member 100 is achieved, but also assembly and fixation with the mounting member 100 are possible.
[0104] In some embodiments of this application, reference is made to Figure 6 and Figure 12 The heat transfer unit 311 includes a heat transfer surface 311a. The heat transfer surface 311a is used to provide an interface for heat transfer with the mounting member 100.
[0105] It is understood that the mounting heat transfer surface 311a can be a portion of the surface around the connecting terminal 310, which can fully fit with the device heat transfer surface 121 to achieve heat transfer.
[0106] In some embodiments of this application, reference is made to Figure 12 The mounting heat transfer surface 311a is constructed as a cylindrical surface. By designing the mounting heat transfer surface 311a as a cylindrical surface, the mounting heat transfer surface 311a and the main terminal heat transfer surface 111a are fully fitted together, which is beneficial for temperature conduction and facilitates the assembly of the mounting part 100 and the connecting terminal 310.
[0107] In some specific embodiments, the axis of the connecting terminal 310 coincides with the center line C1, that is, the mounting heat transfer surface 311a is coaxially arranged with the device heat transfer surface 121. For ease of understanding of this application, the axis of the connecting terminal 310 will also be referred to as the center line C1 below.
[0108] In some specific embodiments, the diameter of the mounting heat transfer surface 311a is the same as the diameter of the device heat transfer surface 121.
[0109] In some embodiments of this application, reference is made to Figures 6 to 8A The terminal heat transfer surface 111 includes an auxiliary terminal heat transfer surface 111b. The auxiliary terminal heat transfer surface 111b is used to provide an interface for heat transfer with the connecting terminal 310 along the auxiliary heat transfer direction. The auxiliary terminal heat transfer surface 111b further increases the heat transfer area between the terminal heat transfer section 110 and the connecting terminal 310.
[0110] It can be understood that the area of the main terminal heat transfer surface 111a is larger than the area of the auxiliary terminal heat transfer surface 111b. Correspondingly, the auxiliary heat transfer direction can be a heat transfer direction other than the main heat transfer direction; more specifically, the auxiliary heat transfer direction intersects with the main heat transfer direction.
[0111] In some specific implementations, the auxiliary heat transfer direction can be a direction parallel to the axial direction of the center line C1 mentioned above.
[0112] In some embodiments of this application, reference is made to Figure 4 , Figure 6 and Figure 12 The connecting terminal 310 also includes a terminal limiting portion 312. The terminal limiting portion 312 is used to limit the position of the mounting member 100 relative to the connecting terminal 310; the auxiliary terminal heat transfer surface 111b is located on the side of the mounting member 100 near the terminal limiting portion 312, so that the terminal limiting portion 312 and the auxiliary terminal heat transfer surface 111b can transfer heat.
[0113] It is understood that the terminal limiting part 312 and the mounting heat transfer part 311 are arranged adjacent to or spaced apart in the axial direction of the connecting terminal 310. The terminal limiting part 312 restricts the mounting member 100 from moving towards the terminal limiting part 312, thereby limiting the mounting member 100. Furthermore, the terminal limiting part 312 can also increase the heat transfer area between the connecting terminal and the mounting member.
[0114] In some embodiments of this application, reference is made to Figure 12 In the radial direction of the connecting terminal 310, at least a portion of the dimension of the terminal limiting portion 312 is larger than the dimension of the mounting heat transfer portion 311.
[0115] It can be understood that the size of the terminal limiting part 312 in the radial direction of the connecting terminal 310 is larger than the size of the mounting heat transfer part 311 in the radial direction. That is, in the radial direction of the connecting terminal 310, the terminal limiting part 312 protrudes relative to the mounting heat transfer part 311.
[0116] In some embodiments of this application, reference is made to Figures 6 to 8A The main terminal heat transfer surface 111a forms the inner ring surface of the terminal heat transfer section 110, and the auxiliary terminal heat transfer surface 111b forms the end face of the terminal heat transfer section 110.
[0117] It can be understood that the main terminal heat transfer surface 111a constitutes the radial boundary of the terminal heat transfer section 110, while the auxiliary terminal heat transfer surface 111b constitutes the axial boundary of the terminal heat transfer section 110.
[0118] To further increase the heat transfer area between the auxiliary terminal heat transfer surface 111b and the connecting terminal 310, in some embodiments of this application, the auxiliary terminal heat transfer surface 111b is constructed as an annular surface.
[0119] It is understandable that the annular surface is also set around the center line C1. However, compared with the closed surface, the two boundaries of the annular surface are set apart radially on the center line C1, while the two boundaries of the closed surface are set apart axially on the center line C1.
[0120] In some specific implementations, the annular surface can be a plane or a cone, etc., and can be designed according to the adaptation requirements of the mounting part 100 and the connecting terminal 310.
[0121] In some embodiments of this application, reference is made to Figures 6 to 8A The auxiliary terminal heat transfer surface 111b is constructed as an annular plane. It can be understood that this annular plane is set perpendicular to the center line C1, so that uniform heat transfer between the auxiliary terminal heat transfer surface 111b and the connecting terminal 310 can be achieved in the auxiliary heat transfer direction.
[0122] In some embodiments of this application, the busbar of the main terminal heat transfer surface 111a intersects with the busbar of the auxiliary terminal heat transfer surface 111b.
[0123] It can be understood that the main terminal heat transfer surface 111a can be regarded as a surface formed by a bus moving along a conductor; while the auxiliary terminal heat transfer surface 111b can be regarded as a surface formed by another bus moving along the same conductor.
[0124] In some specific embodiments, the busbar of the main terminal heat transfer surface 111a is perpendicular to the busbar of the auxiliary terminal heat transfer surface 111b. Correspondingly, the main terminal heat transfer surface 111a and the auxiliary terminal heat transfer surface 111b are perpendicular to each other.
[0125] More specifically, the generatrix of the main terminal heat transfer surface 111a is parallel to the center line C1, and the generatrix of the auxiliary terminal heat transfer surface 111b extends radially along the center line C1.
[0126] In some embodiments of this application, reference is made to Figures 2 to 4 Connector 1 also includes: a first gasket 320.
[0127] The first gasket 320 is disposed between the terminal limiting portion 312 and the mounting member 100; wherein the first gasket 320 is made of at least one of thermally conductive material and flexible material. By providing the first gasket 320, both thermal conductivity efficiency can be improved and a buffering and vibration reduction effect can be achieved.
[0128] In some specific embodiments, the first gasket 320 may be made of thermally conductive silicone. The first gasket 320 is fitted onto the connecting terminal 310 for easy assembly.
[0129] In some embodiments of this application, reference is made to Figures 6 to 8A The device heat transfer section 120 includes a device heat transfer surface 121. The device heat transfer surface 121 is used to provide an interface for heat transfer with the temperature sensor 210. By providing the terminal heat transfer surface 111, heat can be effectively transferred from the mounting member 100 to the temperature sensor 210.
[0130] In some embodiments of this application, the total area of the terminal heat transfer surface 111 is greater than the total area of the device heat transfer surface 121.
[0131] With this area arrangement, during the process of heat converging and transferring from the terminal heat transfer surface 111 to the device heat transfer surface 121, the heat transferred from different areas of the connection terminal 310 to the mounting component 100 can be fully mixed, improving the accuracy of temperature detection; and the size of the required temperature sensor 210 or the number of required temperature sensors 210 can be reduced.
[0132] In some embodiments of this application, reference is made to Figures 6 to 8A The device heat transfer surface 121 includes a near heat transfer surface 121a. The near heat transfer surface 121a provides an interface for heat transfer with the temperature sensor 210 along the near heat transfer direction. The near heat transfer surface 121a can be understood as the portion of the device heat transfer surface 121 that is relatively close to the terminal heat transfer surface 111. To further increase the heat transfer area, the device heat transfer surface 121 also includes a far heat transfer surface 121b. The far heat transfer surface 121b provides an interface for heat transfer with the temperature sensor 210 along the far heat transfer direction. The near heat transfer surface 121a can be understood as the portion of the device heat transfer surface 121 that is relatively far from the terminal heat transfer surface 111.
[0133] Specifically, the near heat transfer surface 121a and the far heat transfer surface 121b are arranged opposite to each other. In other words, the near heat transfer direction and the far heat transfer direction are opposite.
[0134] In some embodiments of this application, reference is made to Figures 6 to 8A At least one of the near heat transfer surface 121a and the far heat transfer surface 121b is constructed as a plane, which is conducive to achieving stable contact between the near heat transfer surface 121a and the far heat transfer surface 121b.
[0135] In some embodiments of this application, reference is made to Figures 6 to 8A The heat transfer surface 121 of the device includes an intermediate heat transfer surface 121c. The intermediate heat transfer surface 121c is used to provide an interface for heat transfer with the temperature sensor 210 along the intermediate heat transfer direction; the intermediate heat transfer surface 121c is located between the near heat transfer surface 121a and the far heat transfer surface 121b.
[0136] It is understood that at least two intermediate heat transfer surfaces 121c are provided between the near heat transfer surface 121a and the far heat transfer surface 121b, and the specific design can be made according to the heat transfer requirements of the temperature sensor 210.
[0137] By employing the combination of the near heat transfer surface 121a, the far heat transfer surface 121b, and the intermediate heat transfer surface 121c, the heat transfer section 120 of the device can transfer heat to the temperature sensor 210 from multiple directions. Furthermore, by setting multiple different heat transfer surfaces, the heat transfer surface 121 of the device can better adapt to the shape of the temperature sensor 210, thereby improving the heat transfer effect.
[0138] Specifically, the two intermediate heat transfer surfaces 121c are arranged opposite to each other. In other words, the heat transfer directions of the two intermediate heat transfer surfaces 121c are arranged in opposite directions.
[0139] In some embodiments of this application, reference is made to Figures 6 to 8A The intermediate heat transfer surface 121c is arranged to intersect with the near heat transfer surface 121a; the intermediate heat transfer surface 121c is also arranged to intersect with the far heat transfer surface 121b. That is, the intermediate heat transfer direction intersects with the near heat transfer direction and the far heat transfer direction respectively, thereby realizing that the heat transfer part 120 of the device can transfer heat to the temperature sensor 210 from multiple directions and improve the heat transfer efficiency.
[0140] In some embodiments of this application, reference is made to Figures 6 to 8A The heat transfer section 120 of the device is configured to have a receiving groove 120a to accommodate the temperature sensor 210. It can be understood that the heat transfer section 120 of the device is not only used to transfer heat to the temperature sensor 210, but also to realize the assembly of the temperature sensor 210 on the mounting part 100.
[0141] Specifically, at least a portion of the wall of the receiving tank 120a is formed by the heat transfer surface 121 of the device; this structural design not only facilitates the installation of the temperature sensor 210, but also provides more uniform thermal contact.
[0142] In some embodiments of this application, reference is made to Figures 6 to 8A The terminal heat transfer part 110 is configured with a ring structure to be fitted onto the connecting terminal 310. This design not only enables rapid heat transfer between the terminal heat transfer part 110 and the connecting terminal 310, but also facilitates the assembly of the connecting terminal 310 and the mounting part 100.
[0143] In some embodiments of this application, reference is made to Figures 6 to 8A The heat transfer section 120 of the device is located on the outer periphery of the heat transfer section 110 of the terminal.
[0144] It is understood that the device heat transfer section 120 and the terminal heat transfer section 110 are located at different radial positions relative to the center line C1, and the distance between the device heat transfer section 120 and the center line C1 is greater than the distance between the terminal heat transfer section 110 and the center line C1.
[0145] This arrangement allows the heat transfer section 120 of the device to maintain a suitable distance from the connection terminal 310. During the process of heat transfer from the connection terminal 310 to the temperature sensor 210, the heat can be fully mixed in the terminal heat transfer section 110 before being applied to the temperature sensor 210 through the device heat transfer section 120, thereby improving the accuracy of temperature detection.
[0146] In some embodiments of this application, the mounting element 100 is made of at least one of ceramic or thermally conductive plastic.
[0147] It is understandable that ceramics possess advantages such as high thermal conductivity and insulation, which improve temperature detection sensitivity and insulation withstand voltage rating. Thermally conductive plastics can be highly thermally conductive, achieving both efficient temperature conduction and the ability to form complex structural components. This characteristic allows for the design of adaptable structures in multiple fields to meet functional requirements. Furthermore, thermally conductive plastics can improve temperature detection sensitivity, reduce the risk of over-temperature runaway, reduce product costs, and enhance overall performance.
[0148] In some specific embodiments, the mounting component 100 can be made of either ceramic or thermally conductive plastic, or a combination of both materials. For example, the terminal heat transfer part 110 is made of ceramic, while the device heat transfer part 120 is made of thermally conductive plastic. This ensures heat conduction while achieving flexible contact between the mounting component 100 and the temperature sensor 210, thus providing a buffering and vibration reduction effect.
[0149] In some embodiments of this application, reference is made to Figure 7 , Figure 8A and Figure 9 The temperature sensor 210 includes a thermistor 211; the thermistor 211 includes a thermistor heat transfer surface 211a. The device heat transfer portion 120 surrounds at least a portion of the thermistor heat transfer surface 211a to allow heat transfer between the device heat transfer portion 120 and the thermistor heat transfer surface 211a. 。
[0150] It can be understood that the thermistor 211 is a type of thermistor whose resistance changes with temperature. The thermistor heat transfer surface 211a can be the surface of the thermistor 211; more specifically, the temperature sensor 210 can be an NTC chip.
[0151] By adopting this approach, the housing of the temperature sensor 210 can be eliminated, and the thermistor 211 of the temperature sensor 210 can be placed directly in the heat transfer section 120 of the device. By taking advantage of the high thermal conductivity of the mounting part 100, the temperature monitoring sensitivity can be improved.
[0152] In some embodiments of this application, reference is made to Figure 3 The temperature sensing component 10 also includes a filling layer 220. The filling layer 220 fills at least between the thermistor heat transfer surface 211a and the device heat transfer part 120. By providing the filling layer 220, the gap between the thermistor heat transfer surface 211a and the device heat transfer part 120 can be fully filled, thereby fixing the temperature sensor 210.
[0153] In some embodiments of this application, the filler layer 220 is made of at least a thermally conductive material. That is, the filler layer 220 can not only be fixed, but also fully adhere to the heat-transfer surface 211a and the heat transfer surface 121 of the device for heat transfer.
[0154] In some specific embodiments, the filler layer 220 may be made of epoxy resin, which is formed by potting and curing after the temperature sensor 210 is placed into the receiving groove 120a.
[0155] In some other embodiments of this application, the mounting part 100 is made of thermally conductive plastic. Before the mounting part 100 is assembled with the connecting terminal 310, the mounting part 100 can be combined with the temperature sensor 210 during the curing process. At this time, there is no need to reserve the receiving groove 120a, which simplifies the assembly of the temperature sensing component 10.
[0156] In some embodiments of this application, reference is made to Figure 6 and Figure 7 The temperature sensing assembly 10 also includes a cable 230 and a low-voltage sheath 240, wherein the cable 230 is connected to the temperature sensor 210 for transmitting temperature signals to the user. The low-voltage sheath 240 is connected to the cable 230 to provide electrical insulation and protect the external terminals of the cable 230.
[0157] In some embodiments of this application, reference is made to Figure 6 and Figure 12 The connection terminal 310 includes a first connection portion 313 and a second connection portion 314. The first connection portion 313 is used to connect a first type of external device; the second connection portion 314 is used to connect a second type of external device; wherein, the heat transfer portion 311 is located between the first connection portion 313 and the second connection portion 314.
[0158] It is understood that one of the first connecting part 313 and the second connecting part 314 realizes the input of current, and the other of the first connecting part 313 and the second connecting part 314 realizes the output of current. The heat transfer part 311 is located between the first connecting part 313 and the second connecting part 314, which can realize the effective detection of the temperature of the connecting terminal 310.
[0159] In some specific implementation methods, refer to Figure 2 and Figure 5 The first type of external device can be another phase-adapted connector 1. In order to reduce wear when the first connection part 313 is plugged into the other phase-adapted connector 1, an anti-touch cap 371 is provided at the end of the first connection part 313.
[0160] The second type of external device can be a conductive copper busbar. More specifically, the second connecting part 314 is also connected to a rivet nut 380. The rivet nut 380 can lock the second connecting part 314 and the conductive copper busbar with bolts, thereby achieving fixation.
[0161] In some embodiments of this application, reference is made to Figure 2 and Figure 13The connector 1 includes a housing 350. The housing 350 has a receiving space 350a, wherein at least a portion of the connecting terminal 310 and at least a portion of the mounting member 100 are respectively mounted in the receiving space 350a. The receiving space 350a provides protection for the connecting terminal 310 and the mounting member 100.
[0162] In some specific embodiments, the housing 350 may be made of insulating materials such as plastic.
[0163] In some embodiments of this application, reference is made to Figure 2 and Figure 4 The outer casing 350 includes a casing-side limiting portion 351. The casing-side limiting portion 351 abuts against the mounting member 100 to limit the position of the mounting member 100 relative to the outer casing 350; the casing-side limiting portion 351 is disposed in the accommodating space 350a.
[0164] It is understood that the shell-side limiting part 351 and the terminal limiting part 312 are located on opposite sides of the mounting member 100, thereby achieving complete axial limiting of the mounting member 100 and improving the stability of the mounting member 100.
[0165] In some specific implementation methods, refer to Figure 2 and Figure 4 Along the axial direction of the center line C1, the heat transfer part 311 is installed between the shell-side limiting part 351 and the terminal limiting part 312.
[0166] In some embodiments of this application, reference is made to Figure 2 and Figure 4 The housing-side limiting portion 351 has a clearance hole 351a. The clearance hole 351a is used to provide a channel through which at least a portion of the connecting terminal 310 passes; the clearance hole 351a is provided through the housing-side limiting portion 351.
[0167] It is understandable that the clearance hole 351a passes through the shell-side limiting part 351 along the center line C1.
[0168] By adopting this solution, the clearance hole 351a is provided to ensure that the housing-side limiting part 351 limits the mounting part while avoiding interference with the connecting terminal 310.
[0169] In some embodiments of this application, reference is made to Figure 2 , Figure 4 and Figure 5 The connector 1 further includes a second gasket 330. The second gasket 330 is disposed between the housing-side limiting portion 351 and the mounting member 100. The second gasket 330 is made of at least a flexible material.
[0170] With this solution, the second gasket 330 serves as a buffer and vibration damping element between the shell-side limiting part 351 and the mounting part 100.
[0171] In some specific embodiments, the second gasket 330 may be made of silicone. The second gasket 330 is fitted onto the connecting terminal 310 for easy assembly.
[0172] In some embodiments of this application, reference is made to Figure 2 , Figure 4 and Figure 5 The connector 1 further includes a terminal seal 340. The terminal seal 340 is used to achieve a seal between the housing-side limiting portion 351 and the connecting terminal 310; at least a portion of the terminal seal 340 is embedded in one of the housing-side limiting portion 351 and the connecting terminal 310, and the terminal seal 340 contacts the other of the housing-side limiting portion 351 and the connecting terminal 310.
[0173] By adopting this solution, the terminal seal 340 enables a self-sealing mechanism to be formed inside the connector 1, preventing water from flowing in along the axial direction of the connector 1.
[0174] In some embodiments of this application, the mounting member 100 has a first positioning structure; the housing 350 has a second positioning structure adapted to the first positioning structure to restrict the rotation of the mounting member 100 relative to the housing 350.
[0175] By adopting this scheme, the first positioning structure and the second positioning structure restrict the rotation of the mounting component 100 relative to the housing 350, thereby improving the stability of the mounting component 100 and the connecting terminal 310.
[0176] In some specific implementations, the first positioning structure and the second positioning structure can cooperate to restrict rotation through methods such as concave-convex fit or pin fit.
[0177] In some embodiments of this application, reference is made to Figure 2 , Figure 3 , Figure 6 , Figure 8A and Figure 13 The first positioning structure is configured as a heat transfer section 120 for a multiplexed device. The second positioning structure includes a positioning groove 350b. The positioning groove 350b is disposed inside the housing 350 and communicates with the accommodating space 350a. At least a portion of the heat transfer section 120 is embedded in the positioning groove 350b to restrict the rotation of the mounting member 100 relative to the housing 350. By cooperating with the positioning groove 350b, the rotation of the mounting member 100 relative to the housing 350 is restricted, which simplifies the structure of the mounting member 100.
[0178] In other embodiments of this application, reference is made to Figure 2 , Figure 3 , Figure 6 , Figure 8B and Figure 13 The first positioning structure includes a positioning protrusion 130. The positioning protrusion 130 is disposed on the outer periphery of the terminal heat transfer portion 110. The second positioning structure includes a positioning groove 350b. The positioning groove 350b is disposed inside the housing 350 and communicates with the accommodating space 350a. At least a portion of the positioning protrusion 130 is embedded in the positioning groove 350b to restrict the rotation of the mounting member 100 relative to the housing 350. More specifically, the positioning protrusion 130 protrudes radially from the terminal heat transfer portion 110.
[0179] In some specific implementation methods, refer to Figure 1 , Figure 2 and Figure 13 The positioning groove 350b is formed by a partial recess in the inner wall of the accommodating space 350a, and extends in a direction parallel to the center line C1. At least a portion of the cable 230 is disposed in the positioning groove 350b, that is, the positioning groove 350b provides a channel for the cable 230 to connect with the temperature sensor 210. The housing 350 is also provided with an outlet 350e, which penetrates the housing 350 radially along the center line C1, and the outlet 350e communicates with the positioning groove 350b, which facilitates the lead-out of the cable 230 from the positioning groove 350b.
[0180] In some embodiments of this application, reference is made to Figure 1 , Figure 2 , Figure 5 , Figures 10 to 14 The connector 1 further includes a retainer 360. The retainer 360 is used to retain the relative position of the connection terminal 310 and the housing 350; wherein the retainer 360 is coupled to the housing 350 and the connection terminal 310 respectively.
[0181] With this solution, the connection terminal 310 and the housing 350 are stably held together as a whole by the setting of the retainer 360.
[0182] In some embodiments of this application, reference is made to Figures 10 to 14 The retaining member 360 includes a first locking portion 361 and a second locking portion 362. The connecting terminal 310 has a limiting groove 310a for the first locking portion 361 to be inserted into, and the housing 350 has a stop portion 353 for the second locking portion 362 to cooperate with.
[0183] It is understood that the limiting groove 310a is located in the accommodating space 350a when the connecting terminal 310 is installed with the housing 350, and the stop part 353 is formed on the wall of the accommodating space 350a; the first locking part 361 and the second locking part 362 can be two different functional structures on the retaining member 360. When the retaining member 360 is inserted into the accommodating space 350a, the first locking part 361 cooperates with the limiting groove 310a, and the second locking part 362 cooperates with the stop part 353 to restrict the retaining member 360 from leaving the housing 350.
[0184] The use of this retainer 360 structure makes the installation and disassembly of the mounting part 100 and the connecting terminal 310 more convenient and the structure more stable.
[0185] In some specific implementation methods, refer to Figure 15 The second locking part 362 can be configured as a resilient latch.
[0186] In some specific implementation methods, refer to Figures 10 to 14 The outer casing 350 is also provided with an assembly groove 350c for inserting the retainer 360. The assembly groove 350c is connected to the accommodating space 350a, and the position of the assembly groove 350c corresponds to that of the limiting groove 310a.
[0187] In some embodiments of this application, reference is made to Figure 12 The extending direction of the limiting groove 310a intersects the axial direction of the connecting terminal 310.
[0188] With this configuration, the engagement between the first locking part 361 and the limiting groove 310a can not only limit the relative position of the connecting terminal 310 and the housing 350 in the axial direction, but also limit the relative rotation of the connecting terminal 310 and the housing 350.
[0189] In some specific embodiments, the extending direction of the limiting groove 310a is perpendicular to the axial direction of the connecting terminal 310.
[0190] In some embodiments of this application, reference is made to Figure 10 , Figure 11 and Figure 15 The retainer 360 is provided with two symmetrical first locking parts 361 and two second locking parts 362. Correspondingly, the connecting terminal 310 is provided with two symmetrical limiting grooves 310a, and the housing 350 is provided with stop parts 353 at symmetrical circumferential positions.
[0191] In some embodiments of this application, reference is made to Figure 1 and Figure 15The retainer 360 further includes a connecting portion 363. The connecting portion 363 is connected between at least two first locking portions 361, combining the two first locking portions 361 into a whole; the connecting portion 363 abuts against the housing 350 when the first locking portion 361 is inserted into the limiting groove 310a.
[0192] By adopting this solution, the abutting engagement between the connecting part 363 and the outer shell 350 can not only limit the insertion depth of the first locking part 361, but also reduce the force on the second locking part 362 in the direction perpendicular to the center line C1, thereby improving the stability and reliability of the retaining member 360.
[0193] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The connecting portion 363 has a limiting protrusion 364. The limiting protrusion 364 is disposed on the side of the connecting portion 363 that abuts against the housing 350. The housing 350 has a slot 350d. The slot 350d is used for at least a portion of the limiting protrusion 364 to be inserted to define the relative position of the connecting portion 363 and the housing 350.
[0194] By adopting this solution, the rotation of the connecting part 363 relative to the outer shell 350 can be limited through the cooperation of the limiting protrusion 364 and the slot 350d, thereby further improving the stability of the retaining part 360.
[0195] In some embodiments of this application, reference is made to Figure 2 The housing 350 includes an end face limiting portion 352. The end face limiting portion 352 is used to abut against the external connector 1 to define the insertion depth. The connector 1 also includes an end face seal 372. The end face seal 372 is fixedly connected to the end face limiting portion 352, thereby providing cushioning between the end face limiting portion 352 and the external connector 1.
