Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector, a sensor, and a vehicle. Background Technology

[0002] With the continuous development of vehicle technology, especially in the development of new energy vehicles, vehicle intelligence is an important development direction. The development of vehicle intelligence will lead to an increasing application of electronic products in vehicles, and therefore the number of connectors used will continue to increase.

[0003] In the existing technology, the housing of the connector and its applicable products (such as sensors) are integrally injection molded. Therefore, different housing molds need to be designed for different products, which is relatively expensive. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing connectors cannot be adapted to different products. This invention provides a connector that can adapt to different products, eliminating the need to design and manufacture different molds for different products, thus reducing production costs.

[0005] To address the aforementioned technical problems, this utility model discloses a connector, comprising:

[0006] A plug-in portion, the plug-in portion including a first electrical connection portion;

[0007] A connecting plate, wherein the plug-in portion is disposed on the connecting plate, and the connecting plate is used for detachable connection with an external connecting seat;

[0008] The second electrical connection part is electrically connected to the first electrical connection part. The second electrical connection part is located on the side of the connection plate opposite to the first electrical connection part and is used to connect with the pins of the external connector.

[0009] Using the above technical solution, the connecting plate and the external connector (such as the external connector of the sensor) can be detachably connected. When it is necessary to adapt the connector to different sensors, simply remove the connecting plate from the external connector to separate the connector from the external connector. Then, the connecting plate can be connected to the external connector of other sensors. There is no need to design different housing molds, which can effectively reduce costs.

[0010] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector in which the plug-in portion and the second electrical connection portion are disposed on both sides of the connecting plate along a first direction, and both the plug-in portion and the second electrical connection portion extend along the first direction.

[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector, wherein the second electrical connection part includes a fixing part, a first elastic connection part and a second elastic connection part, one end of the first elastic connection part is connected to the fixing part, and one end of the second elastic connection part is connected to the fixing part.

[0012] Along the second direction, the other end of the first elastic connecting portion is spaced apart from the fixed portion, and the other end of the second elastic connecting portion is spaced apart from the fixed portion. The other ends of the first elastic connecting portion, the other ends of the second elastic connecting portion, and the fixed portion together define a snap-fit ​​space for snapping the pins of the external connector.

[0013] By adopting the above technical solution, when the connector is connected to the external connector, the other end of the first elastic connection part, the other end of the second elastic connection part, and the fixing part together define a snap-fit ​​space, and the pins of the external connector are snapped into the snap-fit ​​space, which makes the connection between the connector and the external connector more stable.

[0014] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector in which the first elastic connecting part and the second elastic connecting part can switch between a first state and a second state.

[0015] In the first state, the pin is not inserted into the snap-fit ​​space, and along the second direction, the other end of the first elastic connection portion is spaced apart from the fixed portion, and the other end of the second elastic connection portion is spaced apart from the fixed portion;

[0016] In the second state, the pin is inserted into the snap-fit ​​space, the other end of the first elastic connection is pressed and moves away from the fixed part along the second direction, and the other end of the second elastic connection is pressed and moves away from the fixed part along the second direction to abut the pin.

[0017] Using the above technical solution, when the connector provided in this application embodiment is used to adapt to different types of products, the external connectors of different products have pins of different thicknesses. When pins of different thicknesses are inserted into the snap-fit ​​space, since the snap-fit ​​space is formed by the other end of the first elastic connection part, the other end of the second elastic connection part, and the fixing part, the other end of the first elastic connection part and the other end of the second elastic connection part can be pressed and moved away from the fixing part in the second direction to different positions to adapt to pins of different thicknesses. Thus, even when facing pins of different thicknesses, the first elastic connection part and the second elastic connection part can stably connect them to the second electrical connection part.

[0018] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector, wherein the second electrical connection part includes an electrical connection contact point, the electrical connection contact point is electrically connected to the first electrical connection part, the fixing part extends along the first direction, and the electrical connection contact point is located on the side of the fixing part close to the connecting plate. In the second state, the electrical connection contact point is used to contact the pin.

[0019] With the above technical solution, the electrical contact point is located on the side of the fixing part close to the connecting plate along the first direction. Therefore, when the depth of the pin inserted into the snap-fit ​​space along the first direction is close to the connecting plate, the exchange of electrical signals can be realized normally. This makes the exchange of electrical signals more stable and avoids problems such as poor contact caused by improper connection.

[0020] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector, wherein the second electrical connection portion includes an arc-shaped protrusion, the arc-shaped protrusion is disposed on the fixing portion, the arc-shaped protrusion extends along the first direction, along the first direction, the electrical connection contact point is disposed on the side of the arc-shaped protrusion near the connecting plate, and along the second direction, the arc-shaped protrusion is spaced apart from the other end of the first elastic connection portion and the other end of the second elastic connection portion, together defining the snap-fit ​​space.

[0021] Using the above technical solution, the arc-shaped protrusion extends along the first direction. When the pin is connected to the second electrical connection, in the second direction, one side of the pin abuts against the arc-shaped protrusion, and the other side abuts against the other end of the first elastic connection and the other end of the second elastic connection. For pins with a smaller thickness in the second direction, the arc-shaped protrusion allows the other ends of the first and second elastic connections to be pressed and move away from the fixing part in the second direction. This allows the other ends of the first and second elastic connections to form a clamping force on the pin under the action of the restoring force, so that even if the pin has a smaller thickness in the second direction, it still has good stability.

[0022] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector, wherein the connecting plate includes a plurality of connecting holes, the plurality of connecting holes being arranged around the first elastic connecting portion, the fixing portion and the second elastic connecting portion, and the plurality of connecting holes being used for thermal riveting connection with the external connecting seat.

[0023] By adopting the above technical solution, the connecting plate and the metal or non-metal parts to be connected are brought into contact, and the thermoplastic material is heated and softened by ultrasonic waves, hot air, hot mold, or infrared to form a rivet. Then, pressure is applied to the rivet head of the jig and it is shaped to tighten the connector, thereby realizing the detachable connection between the connector and the external connector. When the connector needs to be removed, it is only necessary to heat it to melt the rivet. The embodiment of this application adopts a hot riveting process, which does not require opening a connection hole on the external connector to be connected, and has a wider range of applications.

[0024] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a connector, wherein the connecting plate comprises a polygon and each side of the connecting plate is provided with at least 3 connecting holes.

[0025] By adopting the above technical solution, it is possible to ensure the reliability of the connection between each edge of the connecting plate and the external connector, and avoid situations such as the connector and the external connector falling off due to unreliable connection.

[0026] The present invention also discloses a sensor, which includes at least the connector in any of the above embodiments. The sensor includes an external connector, which includes pins. The external connector is detachably connected to the connecting plate, and the pins are connected to the second electrical connection part.

[0027] Using the above technical solution, different types of sensors can be detachably connected to the same connector, eliminating the need to design a mold for each type of sensor, which can effectively reduce costs.

[0028] The present invention also discloses a vehicle in which the sensor includes at least the sensor described in any of the above embodiments. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] In some embodiments, this application provides a vehicle, see [reference]. Figure 1 The system includes a sensor 10, which includes an external connector 11. The external connector 11 is detachably connected to the connector 20 provided in this embodiment. Exemplarily, the sensor 10 may be a wheel speed sensor, crankshaft / camshaft position sensor, temperature sensor, pressure sensor, knock sensor, etc. It is understood that the connector 20 provided in this embodiment is not limited to applications in the sensor field.

[0043] In some embodiments, see Figure 1 , Figure 2 , Figure 3 This application provides a connector 20, including a plug-in portion 21 and a connecting plate 22. The plug-in portion 21 includes a first electrical connection portion 211, and the connector 20 also includes a second electrical connection portion 23, which is connected to the first electrical connection portion 211. The plug-in portion 21 is used to connect with other systems to realize the exchange of electrical signals between the external connector 11 and other systems. Along a first direction X, the plug-in portion 21 and the second electrical connection portion 23 are disposed on both sides of the connecting plate 22. The connecting plate 22 is used for detachable connection with the external connector 11, and the second electrical connection portion 23 is used for connection with the pins 111 of the external connector 11. Thus, the second electrical connection portion 23 can exchange the electrical signals of the external connector 11 with the first electrical connection portion 211 through the pins 111, thereby realizing the exchange of electrical signals between the external connector 11 and the external system.

[0044] Using the above technical solution, the connecting plate 22 and the external connector 11 (e.g., the external connector 11 of the sensor 10) can be detachably connected. When it is necessary to adapt the connector 20 to different sensors 10, simply remove the connecting plate 22 from the external connector 11 to separate the connector 20 from the external connector 11 as a whole. Then, the connecting plate 22 can be connected to the external connector 11 of other sensors 10. There is no need to design different housing molds, which can effectively reduce costs.

[0045] In some embodiments, see Figure 1 , Figure 2 , Figure 3The plug-in portion 21 and the second electrical connection portion 23 both extend along the first direction X. The plug-in portion 21 includes a slot 212 extending along the first direction X. The first electrical connection portion 211 is disposed on the bottom wall 2121 of the slot 212 and is used to transmit electrical signals from the external connector 11. Exemplarily, the plug-in portion 21 includes a hollow housing 213, which, together with the connecting plate 22, defines the slot 212. Exemplarily, the projection of the housing 213 in the first direction X is a rounded rectangle. It is understood that the shape of the housing 213 is not limited in this embodiment; for example, the housing 213 may also be cylindrical or other shapes.

[0046] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The connecting plate 22 includes multiple connecting holes 221 for thermal riveting connection with the external connecting seat 11. Thermal riveting is a connection process for joining two or more parts. Thermoplastic material is passed through the connecting holes 221, and the connecting plate 22 and the metal or non-metal parts to be connected are brought into contact. The thermoplastic material is heated and softened within the connecting holes 221 using ultrasonic waves, hot air, a hot mold, or infrared radiation to form a rivet 2211. Pressure is then applied to the rivet 2211 using a jig and riveting head to shape it, thereby tightly connecting the connector 20 and the external connecting seat 11. This embodiment uses thermal riveting, eliminating the need for connecting holes 221 on the external connecting seat 11, thus broadening its applicability.

[0047] It is understood that the connector 20 provided in this application embodiment can also be detachably connected to the external connector 11 by means of bolt connection, screw connection, cold riveting, etc., and this application embodiment does not limit this.

[0048] In some embodiments, the connecting plate 22 includes a polygon, and each side of the connecting plate 22 has at least three connecting holes 221. Exemplarily, the connecting plate 22 is rectangular, with three connecting holes 221 on each side of the rectangle. It is understood that the shape of the connecting plate 22 is not limited in this application embodiment; for example, it can be a triangle, a pentagon, a circle, etc. When the connecting plate 22 is circular, at least four connecting holes 221 are provided along the circumferential direction on the edge of the connecting plate 22. Furthermore, the number of connecting holes 221 is not limited in this application embodiment; for example, it can be two, three, four, five, six, seven, etc.

[0049] In some embodiments, see Figure 4 , Figure 5 , Figure 6The second electrical connection portion 23 includes a fixing portion 231, a first elastic connection portion 232, and a second elastic connection portion 233, with a plurality of connection holes 221 arranged around the first elastic connection portion 232 and the second elastic connection portion 233. For example, see [reference needed]. Figure 5 , Figure 6 , Figure 7 and combined Figure 4 Along the third direction Z, the first elastic connecting portion 232 includes a first end 2321 and a second end 2322 spaced apart, and the second elastic connecting portion 233 includes a third end 2331 and a fourth end 2332 spaced apart. The first end 2321 and the second end 2322 are connected by a first arc portion 2323, and the third end 2331 and the fourth end 2332 are connected by a second arc portion 2333. The first end 2321 and the third end 2331 are connected to the fixing portion 231. Along the second direction Y, the second end 2322 and the fourth end 2332 are both spaced apart from the fixing portion 231. The second end 2322, the fourth end 2332, and the fixing portion 231 together define a snap-fit ​​space 234 for snapping onto the pin 111 of the external connector.

[0050] For example, the connector 20 includes three second electrical connection portions 23, which are spaced apart along a third direction Z. Each second electrical connection portion 23 corresponds to each pin 11, and each second electrical connection portion 23 includes a fixing portion 231, a first elastic connection portion 232, and a second elastic connection portion 233. It is understood that the number of second electrical connection portions 23 is not limited in this embodiment; for example, it can be one, two, four, five, etc., and can be set as needed.

[0051] In some embodiments, see Figure 5 , Figure 6 , Figure 7 and combined Figure 4 The first elastic connecting portion 232 and the second elastic connecting portion 233 can switch between a first state and a second state. In the first state, the pin 111 is not inserted into the snap-fit ​​space 234, and along the second direction Y, the third end 2331 and the fourth end 2332 are both spaced apart from the fixing portion 231. In the second state, the pin 111 is inserted into the snap-fit ​​space 234, the second end 2322 of the first elastic connecting portion 232 is pressed and moves away from the fixing portion 231 along the second direction Y, and the fourth end 2332 of the second elastic connecting portion 233 is pressed and moves away from the fixing portion 231 along the second direction Y. Both the second end 2322 of the first elastic connecting portion 232 and the fourth end 2332 of the second elastic connecting portion 233 are used to abut against the pin 111.

[0052] When the connector 20 provided in this application embodiment is used to adapt to different types of products, the external connector 11 of different products has pins 111 of different thicknesses. When pins 111 of different thicknesses are inserted into the snap-fit ​​space 234, since the snap-fit ​​space 234 is formed by the second end 2322 of the first elastic connection part 232, the fourth end 2332 of the second elastic connection part 233 and the fixing part 231, the second end 2322 and the fourth end 2332 can move away from the fixing part 231 along the second direction Y to different positions to accommodate pins 111 of different thicknesses. Thus, even when facing pins 111 of different thicknesses, the first elastic connection part 232 and the second elastic connection part 233 can stably connect them to the second electrical connection part 23.

[0053] In some embodiments, see Figure 5 , Figure 6 , Figure 7 The second electrical connection part 23 includes an electrical connection contact point 235, which is electrically connected to the first electrical connection part 211. The fixing part 231 extends along the first direction X, and the electrical connection contact point 235 is located on the side of the fixing part 231 near the connecting plate 22. In the second state, the electrical connection contact point 235 is used to contact the pin 111.

[0054] For example, the second electrical connection portion 23 includes an arc-shaped protrusion 2311. Along the second direction Y, the arc-shaped protrusion 2311 is disposed on the side of the fixing portion 231 near the first elastic connection portion 232 and the second elastic connection portion 233. The arc-shaped protrusion 2311 extends along the first direction X. Along the first direction X, the electrical connection contact point 235 is disposed on the side of the arc-shaped protrusion 2311 near the connecting plate 22. Along the second direction Y, the arc-shaped protrusion 2311 is spaced apart from the second end 2322 of the first elastic connection portion and the fourth end 2332 of the second elastic connection portion, and together define a snap-fit ​​space 234.

[0055] In some embodiments, see Figure 4 , Figure 5 , Figure 6 and combined Figure 2 The connector 20 also includes a sealing portion 24. Along the first direction X, the sealing portion 24 is disposed on the side of the connecting plate 22 facing away from the insertion portion 21. The sealing portion 24 surrounds the first elastic connecting portion 232 and the second elastic connecting portion 233, and is used to abut against the external connector 11. Exemplarily, the external connector 11 has a sealing groove 112. When the connector 20 and the external connector 11 are connected, the sealing portion 24 is disposed within the sealing groove 112. Exemplarily, the sealing portion 24 can be a sealing ring. By adopting the above technical solution, the sealing performance when the pin 111 is connected to the first elastic connecting portion 232 and the second elastic connecting portion 233 can be improved, preventing liquids and dust from causing poor contact and other malfunctions in the pins.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
