Description

Technical Field

[0001] The utility model relates to the technical field of sensor detection, in particular to a detector, a detection component and a detection tooling. Background Art

[0002] With the popularity of automobiles, automobile safety has received more and more attention. The ABS system (Anti-lock Brake System) is a braking device for vehicles that uses electronic control to prevent the wheels of the vehicle from locking during emergency braking. The ABS system mainly monitors the rotation speed of each wheel through wheel speed sensors, automatically adjusts the brake pump pressure, avoids individual wheels from locking, and improves the safety of the vehicle. Therefore, the performance of the wheel speed sensor is of vital importance to vehicle safety. The plug-in part of the wheel speed sensor mainly includes terminals and terminal locking pieces, wherein the terminals are used to electrically connect to the vehicle components, and the terminal locking pieces are used to lock the terminals to ensure that the wheel speed sensor and the vehicle components can be connected normally.

[0003] The wheel speed sensor must be tested for terminals and terminal locking parts before formal use to ensure the terminal performance is intact and the installation position and size of the terminals and terminal locking parts are correct.

[0004] Currently, independent displacement sensors are used to detect the presence, position, and size of terminal locking parts, and other position sensors are used to detect the installation position and size of the terminals. The current detection equipment has a complex structure and cannot detect the terminals and terminal locking parts at the same time. Two tests are required, which leads to a long process time and low efficiency. Utility Model Content

[0005] The utility model aims to solve the problem that the detection equipment on the current market cannot detect the terminal and the terminal locking piece at the same time. The utility model provides a detector, a detection component and a detection tool, which can detect the terminal and the terminal locking piece at the same time.

[0006] In order to solve the above technical problems, the embodiment of the utility model discloses a detector for detecting a plug-in portion of a sensor, wherein the plug-in portion includes a terminal and a terminal locking member, including:

[0007] A plug-in block, used for plugging with the plug-in portion of the sensor along a first direction, the plug-in block is provided with a first fixing hole and a second fixing hole, the first fixing hole passes through the plug-in block along the first direction, and the second fixing hole passes through the plug-in block along the first direction;

[0008] A switch probe is fixed to the first fixing hole, the switch probe comprises a first connection end and a second connection end, the first connection end and the second connection end can abut against each other along the first direction, the first connection end is used to abut against the terminal locking member along the first direction, the first connection end and the second connection end are respectively used to be connected to a detection circuit, when the terminal locking member pushes the first connection end to abut against the second connection end, the detection circuit is in a closed circuit state;

[0009] A detection probe is fixed in the second fixing hole, the detection probe is used to abut the terminal along the first direction, the detection probe is connected to a test circuit, and when the terminal abuts the detection probe, the test circuit is in a closed circuit state.

[0010] By adopting the above technical solution, by setting the switch probe and the detection probe on the plug-in block, and plugging the plug-in block with the plug-in part of the sensor to be detected, the terminal locking member and the terminal can be detected simultaneously, which can effectively reduce the time of the detection process and improve production efficiency. At the same time, the detector of the embodiment of the present application has a simple structure, is easy to process and use, and has low cost. In addition, when the detector of the embodiment of the present application is not in use, a part of the switch probe and the detection probe is exposed to the outside of the plug-in block, which is convenient for the staff to observe the status of the probes, so as to facilitate the timely replacement and maintenance of the switch probe and the detection probe. Moreover, the detector of the embodiment of the present application fixes the switch probe by setting a first fixing hole, and fixes the detection probe by setting a second fixing hole. The fixing method is simple and effective, and easy to replace.

[0011] Specifically, when the detector detects the plug-in part of the sensor, it plugs the plug-in block into the plug-in part. If the position and size of the terminal locking piece and the terminal of the plug-in part are correct, the terminal locking piece will push the first connection end to abut against the second connection end along the first direction, so that the detection circuit connected to the first connection end and the second connection end forms a closed circuit and sends out an electrical signal. At the same time, the terminal abuts against the detection probe along the first direction, and the detection probe is connected to the test circuit. When the terminal abuts against the detection probe, the test circuit is in a closed circuit state, and the performance of the terminal can be tested, for example, the performance of the terminal at high current.

[0012] That is to say, if the detection circuit and the test circuit are both in a closed circuit state, the position and size of the terminal locking member and the terminal are correct. If any one of the detection circuit and the test circuit or both are in an open circuit state, the position or size of at least one of the terminal locking member and the terminal is incorrect. Exemplarily, if the dimension of the terminal locking member along the first direction is too long, then when the terminal locking member pushes the first connection end to abut against the second connection end, the terminal and the detection probe cannot abut due to the excessive length of the terminal locking member, thus causing the detection circuit to be in a closed circuit state and the test circuit to be in an open circuit state, and the detection of the plug-in part fails.

[0013] According to another specific embodiment of the utility model, the switch probe comprises:

[0014] A conductive needle extending along the first direction, one end of the conductive needle being the first connecting end;

[0015] an insulating layer, sleeved on the conductive needle, wherein the conductive needle can move relative to the insulating layer along the first direction;

[0018] Along the first direction, an end of the conductive outer layer away from the second connection end is used to be connected to the detection circuit;

[0020] In the first state, the first connection end is in contact with the second connection end, the conductive needle is energized with the conductive outer layer, and the detection circuit is in a closed circuit state;

[0023] The first connection end is provided at the second portion;

[0024] In the first state, the first portion and the second portion abut against each other;

[0025] In the second state, the first portion and the second portion are spaced apart from each other along the first direction.

[0026] According to another specific embodiment of the present utility model, the detection probe comprises:

[0028] The connecting tube is sleeved on the connecting needle. The connecting needle can move relative to the connecting tube along the first direction. The connecting needle is electrically connected to the connecting tube.

[0029] According to another specific embodiment of the utility model, along the first direction, the inner wall of the connecting pipe is provided with an annular flange extending along the circumference of the connecting pipe;

[0030] Along the first direction, an elastic member is provided between the annular flange and the connecting needle;

[0031] One end of the elastic member abuts against the annular flange, and the other end abuts against the connecting needle.

[0032] By adopting the above technical solution and arranging an elastic member, when the terminal abuts against the third connection end during the test, the elastic member can play a buffering role, protect the terminal from a large impact force, and effectively protect the terminal from being damaged. In addition, during the test, the elastic member abuts against the connection pin and the annular flange in a compressed state. When the test is completed and the terminal moves away from the third connection end along the first direction, the connection pin rebounds to the state before the test (that is, the elastic member is not compressed) under the action of the elastic member, so as to facilitate the next test.

[0033] According to another specific embodiment of the utility model, the detection probe further includes:

[0034] A fixing pipe is sleeved on the connecting pipe and fixed to the second fixing hole.

[0036] By adopting the above technical solution, by arranging a plurality of saw teeth on the surface of the third connection end, the plurality of saw teeth can increase the contact points between the third connection end and the terminal, thereby ensuring the normal progress of the test.

[0064] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0065] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0066] refer to Figure 1The embodiment of the present application provides a detection tool, including: a detection component and a base 3, wherein the detection component includes a detector 1 and a plug-in portion 2 of a sensor. Exemplarily, the detector 1 is connected to the base 3 in a movable manner along a first direction X, and the plug-in portion 2 is fixed to the base 3.

[0067] Specifically, refer to Figure 2 and Figure 3 The plug-in portion 2 includes a housing 21, a terminal locking member 22 and a terminal 23, wherein the terminal locking member 22 and the terminal 23 are arranged in the housing 21. The detector 1 can be plugged with the plug-in portion 2 of the sensor along the first direction X to detect the position and size of the terminal locking member 22 and the terminal 23, as well as the performance of the terminal 23 (the specific detection method is described below).

[0068] For example, continue to refer to Figure 1 In the embodiment of the present application, the detector 1 is driven to move along the first direction X by the driving assembly so as to be plugged into the plug-in portion 2. The driving assembly includes a driver 31, a driving rod 32, a connecting rod 33 and a fixing rod 34. Along the second direction Y (the second direction Y is perpendicular to the first direction X), the driver 31 is fixed to one side of the detection assembly, and along the first direction X, a driving rod 32 is provided at one end of the driver 31, and the driving rod 32 extends along the first direction X, and the driver 31 can drive the driving rod 32 to move along the first direction X. Along the first direction X, a fixing rod 34 is provided at one end of the detector 1 away from the plug-in portion 2, and the fixing rod 34 and the detector 1 can move synchronously along the first direction X. The driving rod 32 and the fixing rod 34 are connected by a connecting rod 33 so that the driving rod 32 and the fixing rod 34 move synchronously along the first direction X. That is to say, in the embodiment of the present application, the driver 31 drives the driving rod 32 to move along the first direction X, thereby driving the connecting rod 33, the fixing rod 34 and the detector 1 connected in sequence to move synchronously along the first direction X, so as to be plugged into the plug-in part 2, thereby realizing the detection of the terminal locking member 22 and the terminal 22 of the plug-in part 2.

[0069] The embodiment of the present application does not impose any specific restrictions on the specific limitations of the driver 31. For example, the driver 31 is a cylinder, and for another example, the driver 31 and the driving rod 32 are a screw assembly. As long as the driver 31 can drive the driving rod 32 to move along the first direction X, and then drive the detector 1 to move along the first direction X, it will be sufficient.

[0070] Exemplarily, along the third direction Z (the third direction Z is perpendicular to the first direction X and the second direction Y), a slide rail 35 is provided on the upper surface of the base 3, and a slider 36 is provided at the bottom of the detector 1. The slide rail 35 is slidably connected to the slider 36 to increase the smoothness of the movement of the detector 1 along the first direction X.

[0071] It should be noted that the detector 1, detection assembly and detection tooling provided in the embodiment of the present application are applicable to the plug-in parts of various sensors, not limited to wheel speed sensors.

[0072] The specific structure of the detector 1 according to the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0073] refer to Figures 3 to 5 The detector 1 of the embodiment of the present application includes: a plug-in block 11, a switch probe 12 and a detection probe 13.

[0074] Specifically, the plug-in block 11 is plugged with the plug-in portion 2 of the sensor along the first direction X. The plug-in block 11 is provided with a first fixing hole 111 and a second fixing hole 112. The first fixing hole 111 penetrates the plug-in block 11 along the first direction X, and the second fixing hole 112 penetrates the plug-in block 11 along the first direction X.

[0075] Exemplarily, the switch probe 12 is fixed to the first fixing hole 111, and the switch probe 12 includes a first connection end 1211 and a second connection end 1231. The first connection end 1211 and the second connection end 1231 can abut along the first direction X, and the first connection end 1211 is used to abut the terminal locking member 22 along the first direction X. The detection probe 13 is fixed to the second fixing hole 112, and the detection probe 13 is used to abut the terminal 23 along the first direction X. The first connection end 1211 and the second connection end 1231 are respectively connected to a detection circuit. The detection probe 13 is connected to a test circuit.

[0076] When the detector 1 of the embodiment of the present application detects the plug-in portion 2 of the sensor, the plug-in block 11 is plugged into the plug-in portion 2. If the position and size of the terminal locking member 22 and the terminal 23 of the plug-in portion 2 are correct, the terminal locking member 22 will push the first connection end 1211 to abut against the second connection end 1231 along the first direction X, so that the detection circuit connected to the first connection end 1211 and the second connection end 1231 forms a closed circuit and sends out an electrical signal. At the same time, the terminal 23 abuts against the detection probe 13 along the first direction X, and the detection probe 13 is connected to the test circuit. When the terminal 23 abuts against the detection probe 13, the test circuit is in a closed circuit state, and the performance of the terminal 23 can be tested, for example, the performance of the terminal 23 when detecting high current.

[0077] That is to say, if the detection circuit and the test circuit are both in a closed circuit state, the position and size of the terminal locking member 22 and the terminal 23 are correct. If any one of the detection circuit and the test circuit or both are in an open circuit state, the position or size of at least one of the terminal locking member 22 and the terminal 23 is incorrect. Exemplarily, if the dimension of the terminal locking member 22 along the first direction X is too long, then when the terminal locking member 22 pushes the first connection end 1211 to abut against the second connection end 1231, the terminal 23 cannot abut against the detection probe 13 due to the excessive length of the terminal locking member 22, thus causing the detection circuit to be in a closed circuit state and the test circuit to be in an open circuit state, and the detection of the plug-in portion 2 fails.

[0078] Therefore, the detector 1 of the embodiment of the present application can realize simultaneous detection of the terminal locking member 22 and the terminal 23 by setting the switch probe 12 and the detection probe 13 on the plug-in block 11 so that the plug-in block 11 is plugged with the sensor plug-in part 2 to be detected, which can effectively reduce the time of the detection process and improve production efficiency. At the same time, the detector 1 of the embodiment of the present application has a simple structure, is easy to process and use, and has low cost. In addition, when the detector 1 of the embodiment of the present application is not in use, a part of the switch probe 12 and the detection probe 13 are exposed outside the plug-in block 11, which is convenient for the staff to observe the status of the probes, so as to facilitate the timely replacement and maintenance of the switch probe 12 and the detection probe 13. Moreover, the detector 1 of the embodiment of the present application fixes the switch probe 12 by setting a first fixing hole 111, and fixes the detection probe 13 by setting a second fixing hole 112. The fixing method is simple and effective, and easy to replace.

[0079] The embodiment of the present application does not impose any specific limitation on the specific shape of the plug-in block 11. In some possible implementations, the portion of the plug-in block 11 that interfaces with the plug-in portion 2 has the same shape as the component that is plugged into the plug-in portion 2 during actual use.

[0080] For example, reference Figures 2 to 5 In the embodiment of the present application, the plug block 11 is further provided with a docking portion 113. When the plug block 11 is plugged into the plug part 2, the docking portion 113 extends into the housing 21 of the plug part 2, and the docking portion 113 can push the attachment 221 (such as Figure 2 As shown, the terminal locking member 22 is fixed in the housing 21 of the plug-in portion 2 by means of an accessory 221, but Figure 2 The accessory 221 shown in the figure is only a schematic diagram) so that the terminal locking member 22 returns to the correct installation position.

[0081] In some possible implementations, the switch probe 12 includes: a conductive needle 121 , an insulating layer 122 , and a conductive outer layer 123 .

[0082] Specifically, refer to Figure 3 , Figure 4 and Figure 6 , the conductive pin 121 extends along the first direction X, one end of the conductive pin 121 is a first connection end 1211, and the first connection end 1211 is used to abut against the terminal locking member 22. The insulating layer 122 is sleeved on the conductive pin 121, and the conductive pin 121 can move relative to the insulating layer 122 along the first direction X. The conductive outer layer 123 is fixed to the first fixing hole 111, and the conductive outer layer 123 is sleeved on the insulating layer 122, and one end of the conductive outer layer 123 along the first direction X is a second connection end 1231, and the first connection end 1211 and the second connection end 1231 are located on the same side of the plug block 11 along the first direction X.

[0083] Exemplarily, along the first direction X, one end of the conductive needle 121 away from the first connection end 1211 is connected to the detection circuit, and along the first direction X, one end of the conductive outer layer 123 away from the second connection end 1231 is connected to the detection circuit. The switch probe 12 has a first state and a second state.

[0084] In the first state, the first connection end 1211 is in contact with the second connection end 1231, the conductive needle 121 is energized with the conductive outer layer 123, and the detection circuit is in a closed state. In the second state, the first connection end 1211 is not in contact with the second connection end 1231, the conductive needle 121 is not energized with the conductive outer layer 123, and the detection circuit is in an open state.

[0085] In one possible implementation, reference Figure 6 Combined with Figure 4 The conductive needle 121 of the switch probe 12 includes a first portion 1212 and a second portion 1213 spaced apart in the first direction X in the second state, and the first connection end 1211 is disposed at the second portion 1213. When the switch probe 12 is in the first state, that is, when the first connection end 1211 abuts against the second connection end 1231, the first portion 1212 and the second portion 1213 abut against each other, so that the first portion 1212, the second portion 1213 and the conductive outer layer 123 are in contact with each other, thereby forming a closed circuit for the detection circuit.

[0086] Exemplarily, the insulating layer 122 covers a portion of the first portion 1212 to insulate the first portion 1212 from the conductive outer layer 123 , so that before the first portion 1212 and the second portion 1213 come into contact, the detection circuit is always in an open circuit state.

[0087] Exemplarily, an annular protrusion 125 is provided on the inner wall of the conductive outer layer 123, and an abutting protrusion 12311 is provided on the second part 1213. Along the first direction X, an elastic member 124 (such as a spring) is provided between the annular protrusion 125 and the abutting protrusion 12311, and one end of the elastic member 124 abuts against the annular protrusion 125, and the other end abuts against the abutting protrusion 12311.

[0088] In the embodiment of the present application, the switch probe 12 is placed in the second state by means of the elastic member 124, that is, the first portion 1212 and the second portion 1213 are kept in a spaced state (non-contact) along the first direction X, so that the detection circuit is in an open circuit. Only when the terminal locking member 22 pushes the first connection end 1211 to abut against the second connection end 1231 along the first direction X, the second portion 1213 will contact the first portion 1212 in a state of compressing the elastic member 124, so that the detection circuit forms a closed circuit, and the switch probe 12 enters the first state. When the detection is completed, when the terminal locking member 22 and the first connection end 1211 are separated along the first direction X, under the action of the elastic member 124, the second portion 1213 moves away from the first portion 1212 along the first direction X, so that the switch probe 12 enters the second state.

[0089] In some possible implementations, reference Figure 7 Combined with Figure 4 and Figure 5 The detection probe 13 includes: a connecting needle 131 , a connecting tube 132 and a fixing tube 133 .

[0090] The connecting needle 131 extends along the first direction X, and one end of the connecting needle 131 is a third connecting end 1321, which is used to abut against the terminal 23. The connecting tube 132 is sleeved on the connecting needle 131, and the connecting needle 131 can move relative to the connecting tube 132 along the first direction X, and the connecting needle 131 is electrically connected to the connecting tube 132. The fixing tube 133 is sleeved on the connecting tube 132.

[0091] For example, in the embodiment of the present application, the number of the second fixing holes 112 is two, and along the second direction Y, the two second fixing holes 112 are arranged at intervals, and along the third direction Z, the two second fixing holes 112 are arranged above the first fixing hole 11. However, the embodiment of the present application does not specifically limit the positional relationship between the second fixing block 112 and the first fixing hole 111, and can be adjusted according to the specific structure of the sensor plug-in portion 2.

[0092] Accordingly, the number of the detection probes 13 is two, and the electrodes of the two detection probes 13 are opposite to each other. Each detection probe 13 is fixed to a second fixing hole 112 through a fixing tube 133 .

[0093] Exemplarily, along the first direction X, an end of each connecting tube 132 away from the third connecting end 1321 is used to connect to the same test circuit.

[0094] The detection probe 13 has a third state and a fourth state. Specifically, in the third state, each third connection end 1321 abuts against a terminal 23, each connection tube 132 is electrically connected to the test circuit, and the test circuit is in a closed circuit state. In the fourth state, each third connection end 1321 does not contact the terminal 23, and the test circuit is in an open circuit state.

[0095] In some possible implementations, continue to refer to Figure 7 Combined with Figure 2 The inner wall of the connecting tube 132 is provided with an annular flange 134 extending along the circumferential direction R2 of the connecting tube 132. An elastic member (not shown) is provided between the annular flange 134 and the connecting needle 131 along the first direction X. The elastic member may be a spring or other member. For example, one end of the elastic member abuts against the annular flange 134, and the other end abuts against the connecting needle 131.

[0096] The embodiment of the present application is provided with an elastic member. During the test, when the terminal 23 abuts against the third connection end 1321, the elastic member can play a buffering role, protect the terminal 23 from a large impact force, and effectively protect the terminal 23 from being damaged. In addition, during the test, the elastic member abuts against the connection pin 131 and the annular flange 134 in a compressed state. When the test is completed and the terminal 23 moves away from the third connection end 1321 along the first direction X, under the action of the elastic member, the connection pin 131 rebounds to the state before the test (that is, the elastic member is not compressed) to facilitate the next test.

[0097] In some possible implementations, continue to refer to Figure 7 Along the first direction X, the surface of the third connection end 1321 for contacting with the terminal 23 is provided with a plurality of serrations 1322 , and the plurality of serrations 1322 can increase the contact points between the third connection end 1321 and the terminal 23 , thereby ensuring the normal progress of the test.

[0098] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
