Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sensor, especially a wire clamp and sensor. BACKGROUND

[0002] In the automobile interior, when the sensor's winding shaft assembly and the whole vehicle wire harness carry out signal transmission, generally, the wire harness of the sensor is used to achieve electrical connection between the two. After one end of the wire harness of the sensor is electrically connected with the winding shaft assembly, the two are usually fixedly connected by injection molding, at this time, the wire harness needs to be inside the injection molding part to ensure that the wire harness does not leak. But in the injection molding process, due to the impact force of the injection molding material, the wire harness is easily separated from the injection molding range, and then the wire harness is exposed, which has a bad effect on the service life of the wire harness. SUMMARY

[0003] The utility model discloses a wire clamp and sensor, through the combination of the accommodating cavity and the limiting structure, the wire harness is always placed in the injection molding part range, even if in the injection molding process, the wire harness is not separated from the injection molding range by the impact force of the injection molding material, so that the wire harness is not exposed, and the service life of the wire harness is prolonged.

[0004] To solve the above technical problems, the embodiment of the utility model discloses a wire clamp, the wire clamp comprises:

[0005] The positioning part, the first accommodating part, the curved accommodating part and the second accommodating part are connected in sequence, the first accommodating part, the curved accommodating part and the second accommodating part jointly define a through accommodating cavity, and the accommodating cavity is used for accommodating the wire harness from the outside world;

[0006] The positioning part is used for abutting with the pin of the sensor from the outside world, the first accommodating part comprises a first opening end, the positioning part is located at the first opening end, the positioning part and the first opening end define a first gap and a second gap, and the first gap and the second gap are used for the signal line of the wire harness accommodated in the accommodating cavity to extend out;

[0007] The limiting structure is connected with the second accommodating part, the limiting structure is located above the accommodating cavity in the direction perpendicular to the accommodating cavity, the limiting structure and the accommodating cavity define a limiting area, and the limiting area is used for fixing the wire harness from the outside world.

[0008] The technical scheme is adopted, the wire harness is accommodated in the accommodating cavity, and the limiting structure can fix the wire harness in the limiting area in the direction perpendicular to the accommodating cavity, so that the wire harness is prevented from separating from the accommodating cavity. The combination of the accommodating cavity and the limiting structure enables the wire harness to be always positioned in the range of the injection molding part, so that the wire harness cannot be separated from the injection molding range even if the wire harness is impacted by the injection material during the injection molding process, thereby avoiding the exposure of the wire harness and prolonging the service life of the wire harness.

[0009] During the injection molding process, the positioning portion abuts against the pins of the sensor at one end of the wire clamp, and the wire clamp is positioned and fixed through the abutting force. At the other end of the wire clamp, a special wire pressing structure is arranged in the operation field to position the wire harness, and the other end of the wire clamp is also positioned and fixed. Therefore, even if the wire clamp is impacted by the injection material, the wire clamp can still be fixed in the injection molding range, that is, the wire harness can be fixed in the injection molding range, and the smooth injection molding process is ensured.

[0010] In addition, in the prior art, after the signal line of the wire harness is connected with the pins before injection molding, the wire harness is usually pulled to keep the wire harness in a tight state during the injection molding process. If the wire harness is in a slack state, the wire harness is easily separated from the injection molding range and exposed due to the impact of the injection material. However, due to the existence of the pulling force, the pins of the sensor are easily deformed, and then a short circuit is caused. In the technical scheme, the positioning portion abuts against the pins, so that the pins are not connected with each other even if the pins are impacted by the injection material, and the risk of short circuit is effectively avoided.

[0011] The curved accommodating portion is arranged between the first accommodating portion and the second accommodating portion, that is, the first accommodating portion and the second accommodating portion have different extension directions respectively. By changing the extension directions of the first accommodating portion and the second accommodating portion, the direction of the wire harness can be changed accordingly, the flexibility of the wire harness installation is improved, and products with different angle wire harnesses can be produced accordingly.

[0012] According to another specific embodiment of the utility model, one side of the second accommodating portion has a bottom wall in the circumferential direction, the bottom wall is arranged in a spaced manner with the limiting structure to form an opening, the opening is used for the wire harness outside to enter the limiting area, and the distance from one end of the limiting structure away from the second accommodating portion to the bottom wall is less than the diameter of the wire harness outside.

[0013] The technical scheme is adopted, the wire harness is accommodated in the accommodating cavity, and the limiting structure can fix the wire harness in the limiting area in the direction perpendicular to the accommodating cavity, so that the wire harness is prevented from separating from the accommodating cavity. The combination of the accommodating cavity and the limiting structure enables the wire harness to be always positioned in the range of the injection molding part, so that the wire harness cannot be separated from the injection molding range even if the wire harness is impacted by the injection material during the injection molding process, thereby avoiding the exposure of the wire harness and prolonging the service life of the wire harness.

[0014] Since the distance from the end of the limiting structure away from the second accommodating part to the bottom wall is smaller than the diameter of the wire harness, when the wire harness is placed into the accommodating cavity, the operator needs to slightly apply some pressure to the wire harness to force the wire harness to enter the limiting area from the opening. Once the wire harness enters the limiting area, the wire harness cannot leave the limiting area from the opening without external force, thereby achieving the purpose of fixing the wire harness.

[0015] According to another specific embodiment of the utility model, the curved accommodating part comprises a blocking part, the blocking part is located at one end of the bottom wall close to the curved accommodating part, and the blocking part is used for fixing the wire harness accommodated in the accommodating cavity.

[0016] By adopting the above technical scheme, part of the wire harness is located in the curved accommodating part, at this time, the wire harness is subjected to a bending moment, stress is generated in the wire harness to resist the bending trend, in other words, the part is subjected to a bending force. Without the blocking part, the wire harness is easy to separate from the accommodating cavity at the opening of the second accommodating part. After the blocking part is arranged, even if the wire harness is subjected to the impact force of the injection molding part and the bending force of itself during the injection molding process, the wire harness will not accidentally slide out from the position of the blocking part and the opening of the second accommodating part, thereby ensuring the fixation of the wire harness.

[0017] According to another specific embodiment of the utility model, the first accommodating part extends along a first direction, and a top end of the positioning part comprises chamfers arranged on opposite sides along the first direction.

[0018] By adopting the above technical scheme, when the positioning part is connected with the pins of the sensor, the positioning part needs to be inserted between the two pins from below through the top end. By arranging the chamfers on opposite sides along the first direction at the top end of the positioning part, the surface area of the top end can be reduced. At this time, the top end with the reduced surface area is more easy to be inserted between the pins, so that the positioning part can be more smoothly inserted between the pins, thereby guiding the insertion of the positioning part, reducing the resistance and jamming phenomenon in the insertion process, and improving the efficiency and accuracy of the connection between the positioning part and the pins.

[0019] According to another specific embodiment of the utility model, the cross section of the first accommodating part is arc-shaped.

[0020] By adopting the above technical scheme, the cross section of the first accommodating part is attached to the outer surface of the wire harness, thereby facilitating the accommodation of the wire harness.

[0021] According to another specific embodiment of the utility model, the positioning part, the first accommodating part, the curved accommodating part and the second accommodating part are integrally formed.

[0022] The embodiment of the utility model also discloses a sensor, the sensor comprises:

[0023] The wire clamp according to any one of the preceding aspects;

[0024] The wire reel assembly comprises a first pin and a second pin, and the first pin and the second pin are respectively in abutment with two sides of the positioning portion.

[0025] The wire harness is located in the accommodating cavity, one end of the wire harness comprises a first signal line and a second signal line, and the other end of the wire harness is used for being connected with a vehicle body wire harness in the outside world, the first signal line is stretched out from the first gap by the accommodating cavity and is connected with the first pin, and the second signal line is stretched out from the second gap by the accommodating cavity and is connected with the second pin.

[0026] According to the technical scheme, the wire harness is located in the accommodating cavity, and in the injection molding process, at one end of the wire clamp, the first pin and the second pin are respectively in abutment with two sides of the positioning portion, and the abutment force at this position is used for realizing the positioning and fixing of the wire clamp, that is, the positioning and fixing of the wire harness. At the other end of the wire clamp, a wire pressing structure specially arranged in the operation site is used for positioning the wire harness, and the positioning and fixing of the other end of the wire clamp are realized. Therefore, even if the wire clamp is impacted by the injection molding material, the wire clamp can still be fixed in the injection molding range, that is, the wire harness can be fixed in the injection molding range, and the smooth progress of the injection molding process is ensured.

[0027] In addition, the two sides of the positioning portion are respectively in abutment with the first pin and the second pin, so that even if the first pin and the second pin are impacted by the injection molding material, the first pin and the second pin will not be connected with each other due to the existence of the positioning portion, and the risk of short circuit is effectively avoided.

[0028] According to another specific embodiment of the utility model, the wire harness comprises an intermediate portion, and the intermediate portion is in abutment with the blocking portion of the second accommodating portion. BRIEF DESCRIPTION OF DRAWINGS

For those skilled in the art, the specific meaning of the above terms in the present embodiment can be understood according to the specific circumstances.

[0051] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0052] Reference Figures 1 to 3 The present embodiment provides a sensor 100, which comprises a wire clamp 10, a wire winding shaft assembly 20 and a wire harness 30. The wire clamp 10 comprises a positioning portion 11 and a receiving cavity 15, and the wire harness 30 is located in the receiving cavity 15. One end of the wire harness 30 comprises a first signal line 31 and a second signal line 32, and the other end of the wire harness 30 is used for connecting with a vehicle body wire harness 200 outside.

[0053] The wire winding shaft assembly 20 comprises a first pin 21 and a second pin 22, and the first pin 21 and the second pin 22 respectively abut against both sides of the positioning portion 11. The first signal line 31 and the second signal line 32 respectively extend out of the receiving cavity 15 and are respectively connected with the first pin 21 and the second pin 22.

[0054] By adopting the above technical scheme, the wire winding shaft assembly 20 of the sensor 100 transmits signals with the vehicle body wire harness 200 through the wire harness 30. After one end of the wire harness 30 is electrically connected with the wire winding shaft assembly 20, the two are fixedly connected by injection molding.

[0055] In the injection molding process, at one end of the wire clip 10, the first pin 21 and the second pin 22 are respectively in abutment with the two sides of the positioning portion 11, and the positioning and fixing of the wire clip 10 is realized through the abutment force at this position, that is, the positioning and fixing of the wire harness 30 is realized. At the other end of the wire clip 10, a special wire pressing structure is arranged in the operation site to position the wire harness 30, and the positioning and fixing of the other end of the wire clip 10 is realized. Therefore, even if the wire clip 10 is impacted by the injection molding material, it can still be fixed within the injection molding range, that is, the wire harness 30 can be fixed within the injection molding range, ensuring the smooth progress of the injection molding process.

[0056] In addition, in the prior art, before injection molding, the operator connects the first signal line 31 of the wire harness 30 with the first pin 21, and the second signal line 32 with the second pin 22, respectively, and then usually pulls the wire harness 30 a little to keep the wire harness 30 in a tight state during the injection molding process. If the wire harness 30 is in a loose state, it is easy to be impacted by the injection molding material and be pushed out of the injection molding range, causing the wire harness 30 to be exposed. However, due to the existence of the pulling force and the fact that the first pin 21 and the second pin 22 are made of metal, the first pin 21 and the second pin 22 of the wire reel assembly 20 are easy to be deformed by pulling, which in turn leads to short circuit. In the present technical solution, the two sides of the positioning portion 11 are respectively in abutment with the first pin 21 and the second pin 22, so that even if the first pin 21 and the second pin 22 are impacted by the injection molding material, the first pin 21 and the second pin 22 will not be in contact with each other due to the existence of the positioning portion 11, effectively avoiding the risk of short circuit.

[0057] It should be noted that the number of signal lines included in the wire harness 30 is not specifically limited in the embodiments of the present application, for example, in other possible implementations, the number of signal lines included in the wire harness 30 can be three, four, etc. The number of pins included in the wire reel assembly 20 is not specifically limited in the embodiments of the present application, for example, in other possible implementations, the number of pins included in the wire reel assembly 20 can be three, four, etc. If the number of pins is three, correspondingly, the number of positioning portions 11 at this time is two; if the number of pins is four, correspondingly, the number of positioning portions 11 at this time is three. The number of signal lines, pins and positioning portions 11 is determined by the actual situation.

[0058] Next, the wire clip 10 will be described in detail.

[0059] In some possible implementations, referring to Figures 2 to 4 , the wire clip 10 includes a positioning portion 11, a first accommodating portion 12, a curved accommodating portion 13 and a second accommodating portion 14 connected in sequence, and the first accommodating portion 12, the curved accommodating portion 13 and the second accommodating portion 14 jointly define a through accommodating cavity 15.

[0060] The first accommodating portion 12 extends along a first direction X, and a cross section of the first accommodating portion 12 is arc-shaped. The first accommodating portion 12 includes a first open end 121, and the positioning portion 11 is located at the first open end 121. The positioning portion 11 and the first open end 121 define a first gap 122 and a second gap 123. The first signal line 31 of the wire harness 30 extends from the first gap 122 and is connected to the first pin 21, and the second signal line 32 extends from the second gap 123 and is connected to the second pin 22. The second accommodating portion 14 extends along a second direction Y intersecting the first direction X.

[0061] The wire clamp 10 further includes a limiting structure 16 in an arc-shaped structure. The limiting structure 16 is connected to the second accommodating portion 14 and is located above the accommodating cavity 15 along a third direction Z perpendicular to the accommodating cavity 15, that is, the third direction Z is perpendicular to the first direction X. The limiting structure 16 and the accommodating cavity 15 define a limiting area 17 for fixing the wire harness 30. Figure 3

[0062] With the above technical solutions, the wire harness 30 is located in the accommodating cavity 15 of the wire clamp 10, and the limiting structure 16 can fix the wire harness 30 in the limiting area 17 along the third direction Z perpendicular to the accommodating cavity 15, so as to avoid the wire harness 30 from being separated from the accommodating cavity 15. The combination of the accommodating cavity 15 and the limiting structure 16 can keep the wire harness 30 within the range of the injection molding part. Even if the wire harness 30 is impacted by the injection material during the injection molding process, the wire harness 30 will not be separated from the injection range, thereby avoiding the exposure of the wire harness 30 and prolonging the service life of the wire harness 30.

[0063] In addition, the curved accommodating portion 13 is arranged between the first accommodating portion 12 and the second accommodating portion 14, and the first accommodating portion 12 and the second accommodating portion 14 have different extension directions, and the included angle between the two extension directions is α, which can be 70°, 76°, 87°, 112°, etc. That is, by changing the extension directions of the first accommodating portion 12 and the second accommodating portion 14, the running direction of the wire harness 30 can be changed accordingly, and the flexibility of the installation of the wire harness 30 is improved, so that products with different angle wiring can be produced accordingly.

[0064] The cross section of the first accommodating portion 12 is arc-shaped and is in close contact with the outer surface of the wire harness 30, so as to facilitate the accommodation of the wire harness 30.

[0065] In some possible embodiments, with reference to Figures 2 to 4 along the circumferential direction R, one side of the second accommodating portion 14 has a bottom wall 141. The bottom wall 141 is spaced apart from the limiting structure 16 along the third direction Z to form an opening 142 for the wire harness 30 to enter the limiting area 17. The distance d from the end of the limiting structure 16 away from the second accommodating portion 14 to the bottom wall 141 is less than the diameter of the wire harness 30.​

[0066] With the above technical solution, since there is no limiting structure 16 above the first accommodating portion 12, the operator can directly place a part of the wire harness 30 in the accommodating cavity 15. However, there is a limiting structure 16 above the second accommodating portion 14, so it is difficult for the operator to directly place another part of the wire harness 30 in the accommodating cavity 15. Therefore, the operator needs to bend the wire harness 30 through the opening 142 of the second accommodating portion 14 and enter the accommodating cavity 15 through the opening 142.

[0067] Since the distance d from the end of the limiting structure 16 away from the second accommodating portion 14 to the bottom wall 141 is smaller than the diameter of the wire harness 30, when the wire harness 30 is placed in the accommodating cavity 15, the operator needs to slightly apply some pressure to the wire harness 30 to force the wire harness 30 to enter the limiting area 17 from the opening 142. Once the wire harness 30 enters the limiting area 17, without external force, since the diameter of the wire harness 30 is greater than the distance d from the end of the limiting structure 16 away from the second accommodating portion 14 to the bottom wall 141, the wire harness 30 cannot leave the limiting area 17 from the opening 142, thereby achieving the purpose of fixing the wire harness 30.

[0068] In some possible implementation manners, referring to Figures 2 to 4 The bending accommodating portion 13 includes a blocking portion 131 located at one end of the bottom wall 141 close to the bending accommodating portion 13, and the blocking portion 131 is used for fixing the wire harness 30 accommodated in the accommodating cavity 15. The wire harness 30 includes a middle portion 33 located between one end of the wire harness 30 and the other end of the wire harness 30, and the middle portion 33 abuts against the blocking portion 131.

[0069] With the above technical solution, the middle portion 33 of the wire harness 30 is located in the bending accommodating portion 13, at this time, the middle portion 33 is subjected to bending moment, and stress is generated inside to resist the bending trend, in other words, this part is subjected to bending force. Without the blocking portion 131, the wire harness 30 is easy to separate from the accommodating cavity 15 at this position and the opening 142 of the second accommodating portion 14. After the blocking portion 131 is arranged, even if the wire harness 30 is subjected to the impact force of the injection molding part and the bending force of itself during the injection molding process, the wire harness 30 will not accidentally slide out from the position of the blocking portion 131 and the opening 142 of the second accommodating portion 14, thereby ensuring the fixation of the wire harness 30.

[0070] It should be noted that the shape of the blocking portion 131 is not specifically limited in the embodiments of the present application, for example, in other possible implementation manners, the shape of the blocking portion 131 can be a cube, an irregular body, or the like.

[0071] In some possible implementation manners, referring to Figures 2 to 4The top end of the positioning part 11 comprises chamfers 111 arranged on opposite sides along the first direction X.

[0072] With the above technical solution, when the positioning part 11 is connected with the first pin 21 and the second pin 22 of the sensor 100, the positioning part 11 needs to be inserted from below through the top end between the first pin 21 and the second pin 22 (as shown in the middle direction a). By arranging the chamfers 111 on the top end of the positioning part 11, the surface area of the top end can be reduced. At this time, the top end with reduced surface area is easier to be inserted between the first pin 21 and the second pin 22, so that the positioning part 11 can be more smoothly inserted between the first pin 21 and the second pin 22, which plays a guiding role for the insertion of the positioning part 11, reduces the resistance and jamming phenomenon in the insertion process, and improves the efficiency and accuracy of the connection of the positioning part 11 with the first pin 21 and the second pin 22. Figure 2

[0073] In some possible embodiments, referring to Figures 2 to 4 The positioning part 11, the first accommodating part 12, the curved accommodating part 13 and the second accommodating part 14 are integrally formed.

[0074] Although the present application has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood by the skilled in the art that the foregoing is a further detailed description of the present application in connection with specific embodiments, and the specific implementation of the present application should not be limited to these descriptions. Those skilled in the art can make various changes in form and details, including making a number of simple derivations or substitutions, without departing from the spirit and scope of the present application.​
