Description

Technical Field

[0001] The present application relates to the technical field of wire harness testing, and in particular to a detection device and a detection equipment. Background Art

[0002] The core components of the wiring harness include terminals, wires, sheaths and secondary locks. The wires are stripped at both ends and crimped with the terminals, and then the crimped terminals and secondary locks are installed inside the sheath. The terminals and secondary locks installed inside the sheath are generally called connectors.

[0003] In order to ensure the reliability of terminal crimping, the wiring harness conductivity must be tested. However, in the related art, when testing the connector of the wiring harness, only the presence of the terminal can be detected, but the loose fixation of the terminal cannot be detected. Utility Model Content

[0004] In view of the above problems, the present application provides a detection device and a detection equipment, which can solve or alleviate the problems of low detection efficiency and low detection accuracy of wiring harness continuity detection.

[0005] In a first aspect, the present application provides a detection device for conducting a wire harness. The wire harness includes a connector. The detection device includes a detection needle and a base, wherein the detection needle is arranged on the base.

[0006] The detection needle includes an elastic member, a first part and a second part. The elastic member is located between the first part and the second part. The first part can move relative to the second part.

[0007] The detection device is configured such that when the terminal of the connector abuts against the first part, the first part overcomes the elastic force of the elastic member under the force of the terminal and contacts the second part to verify that the terminal is conductive, and the first part does not overcome the elastic force of the elastic member under the force of the terminal and contacts the second part to verify that the terminal is not conductive.

[0008] In the above detection device, an elastic member is provided between the first part and the second part, and the terminal of the connector overcomes the elastic force of the elastic member so that the first part and the second part are in contact and connected. Terminals that are not firmly installed cannot overcome the elastic force of the elastic member, that is, the first part and the second part cannot be connected, so the presence or absence of the terminal on the connector and the degree of firmness of the installation can be detected.

[0009] According to some embodiments of the present application, the detection needle further includes a shell, and the second part, the elastic member and the first part are sequentially mounted on the shell, and the first part is movable relative to the shell.

[0010] In the above technical solution, the shell can be used to support and fix the first part, the elastic member and the second part, the elastic member isolates the first part and the second part, the second part and the elastic member are fixed in the shell, and the first part is movable relative to the shell. In this way, the shell supports and fixes the elastic member and the second part, and when the terminal of the connector contacts the first part, the first part moves relative to the shell and the second part under the force of the terminal until the first part overcomes the elastic force of the elastic member and contacts the two parts, which indicates that the terminal is firmly installed in the connector, thereby detecting the presence of the terminal in the connector and the degree of firmness of the terminal installation.

[0011] According to some embodiments of the present application, the detection needle further includes an insulating member, and the insulating member is disposed between the housing and the second part so that the first part and the second part are not conductive when they are not in contact.

[0012] In the above technical solution, the insulating member is arranged between the housing and the second part, and is used to isolate the housing and the second part, so as to prevent the first part and the second part from being conductive when the terminal contacts the first part but the first part and the second part are not in contact, when one or both of the housing and the elastic member are conductive. Providing the insulating member between the housing and the second part can make the detection result more reliable.

[0013] According to some embodiments of the present application, the base includes a detection piece, the detection piece defines a detection channel, the detection piece is arranged on the top of the detection needle, the top of the first part corresponds to the position of the detection channel, and the terminal contacts the first part through the detection channel.

[0014] In the above technical solution, the terminal contacts the first part of the detection needle after passing through the detection channel. The detection channel is set to detect whether the terminal in the connector is tilted. If the probe installed in the connector is installed crookedly, it cannot pass through the detection channel, thereby detecting the installation condition of the terminal in the connector.

[0015] According to some embodiments of the present application, the detection device includes a locking mechanism and a locking switch, and the locking mechanism and the locking switch are arranged on the base, and the locking switch is configured to enable the locking mechanism to lock the connector on the base when the terminal contacts the first part through the detection channel.

[0016] In the above technical solution, the locking mechanism is used to lock the connector on the base. After the connector is installed on the detection device, the locking switch is triggered. The locking switch can enable the locking mechanism to fix the connector on the base to avoid unstable connection between the connector and the detection pin and affect the test results.

[0017] According to some embodiments of the present application, the locking mechanism includes a locking plate. When the locking switch triggers the locking mechanism, the locking plate extends out and abuts against the connector to lock the connector to the base.

[0018] In the above technical solution, the locking mechanism fixes the connector to the base through the locking piece. After the connector is installed on the detection device, the locking switch is triggered to control the locking piece of the locking mechanism to extend and fix the connector to the base. The locking piece presses against the connector to fix it, so that the locking mechanism can reliably fix the connector.

[0019] According to some embodiments of the present application, the locking mechanism is configured to unlock the connector from the base upon receiving an unlocking signal.

[0020] In the above technical solution, when the wire harness is qualified, the detection machine sends an unlocking signal. When the locking mechanism receives the unlocking signal, it releases the lock on the connector, so that the tester can remove the wire harness from the detection device. When the detection machine does not send an unlocking signal, the locking mechanism remains locked, so that the wire harness that fails the detection cannot be removed, thereby preventing the occurrence of false detection and missed detection.

[0021] According to some embodiments of the present application, the connector has a first positioning portion, the base includes a second positioning portion corresponding to the shape of the first positioning portion, and when the first positioning portion and the second positioning portion are positioned and connected to each other, the terminal contacts the first part through the detection channel.

[0022] In the above technical solution, the connector has a first positioning portion, and a second positioning portion matching the shape of the first positioning portion is provided on the base. Therefore, the connector can be installed on the base only when the first positioning portion and the second positioning portion are positioned and connected to each other. By providing the second positioning portion on the base, it is possible to check whether the connector of the wiring harness is used incorrectly and whether the installation direction of the connector is correct.

[0023] According to some embodiments of the present application, the connector includes a secondary lock, the detection device includes a first detection switch, the first detection switch is arranged on the base, and the first detection switch is configured to trigger the in-place signal of the secondary lock when the secondary lock conflicts with the first detection switch.

[0024] In the above technical solution, the connector includes a secondary lock, and a first detection switch is provided on the base. After the connector is installed on the base, the position of the secondary lock can touch the first detection switch. After the first detection switch is triggered, a signal indicating that the secondary lock is in place can be issued, indicating that the secondary lock has been installed in this connector. In this way, the installation status of the secondary lock in the connector of the wiring harness can be detected.

[0025] According to some embodiments of the present application, the connector includes a sealing ring, the detection device includes a second detection switch, the second detection switch is arranged on the base, and the second detection switch is configured to trigger the sealing ring in-place signal when the sealing ring contacts the second detection switch.

[0026] In the above technical solution, the connector includes a sealing ring, and a second detection switch is arranged on the base. After the connector is installed on the base, the position of the sealing ring can touch the second detection switch. After the second detection switch is triggered, a sealing ring in-place signal can be issued, indicating that the sealing ring has been installed in this connector. In this way, the installation status of the sealing ring in the connector of the wiring harness can be detected.

[0027] According to some embodiments of the present application, the detection device includes a fastener, and the base is fixedly connected to the workbench via the fastener.

[0028] In the above technical solution, the base is fixed on the workbench by fasteners. When testing the wiring harness, the detection device needs to be connected to the detection machine. At the same time, the detection device needs to plug and unplug the connectors of multiple wiring harnesses and the detection device. Using fasteners for fixing can stabilize the position of the detection device and facilitate detection.

[0029] In a second aspect, the present application provides a detection device, which includes the detection apparatus described in any one of the above embodiments.

[0030] In the above detection device, an elastic member is arranged between the first part and the second part, and the terminal of the connector overcomes the elastic force of the elastic member to make the first part and the second part contact and conduct. Terminals that are not firmly installed cannot overcome the elastic force of the elastic member, that is, the first part and the second part cannot be conducted, so the presence or absence of the terminal on the connector and the degree of firmness of the installation can be detected.

[0031] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0052] The wiring harness is a component used to transmit electricity. The core components of the wiring harness include terminals, wires, sheaths, and secondary locks. The wires are stripped at both ends and crimped with the terminals, and then the crimped terminals are inserted into the sheath to form a wiring harness.

[0053] After the terminal and secondary lock are installed inside the sheath, it is generally called a connector. Some connectors with waterproof requirements will also be equipped with sealing rings.

[0054] In order to detect the reliability of the crimping between the terminal and the wire harness, whether the terminal is inserted into the sheath properly, and the correctness of the terminal insertion sequence, the continuity of the wire harness needs to be tested.

[0055] Wire harness continuity testing is a method used to test whether there is a good electrical connection between the wires in a wire harness. During the manufacturing and installation process, the wire harness is usually composed of multiple wires that are connected to different devices or electronic components. The wire harness continuity test can ensure that the connection between these wires is correct for the normal operation of the circuit.

[0056] Wire harness continuity testing is a key step in electronics manufacturing, used to verify whether the electrical connection between wires in the wire harness is reliable. This test ensures smooth operation of the circuit and prevents failures, damage and even safety hazards caused by connection problems. Through wire harness continuity testing, potential connection problems can be discovered and resolved in advance to ensure product quality and reliability.

[0057] In the related art, when conducting a continuity test on a wiring harness, a test probe is energized and contacts the terminal, and the presence of the terminal and whether the terminal insertion sequence is correct can be verified by checking the test result.

[0058] However, when the test probe contacts the terminal, when the terminal is not fully inserted into the housing, the terminal may also contact the test probe, so that it is impossible to detect whether the terminal is fully inserted into the housing.

[0059] In addition, in the inspection of the wiring harness, a full visual inspection is required to check whether the connector is used incorrectly, whether the secondary lock and the sealing ring are properly assembled, and whether the terminal is skewed. Appearance inspection is usually performed manually, which is time-consuming and labor-intensive and prone to mis-inspection and missed inspection.

[0060] Based on the above considerations, in order to solve or alleviate the problems of low detection efficiency and low detection accuracy of wire harness continuity detection, the present application provides a detection device for wire harness continuity testing. The wire harness includes a connector. The detection device includes a detection needle and a base, and the detection needle is arranged on the base.

[0061] The detection needle comprises an elastic member, a first part and a second part. The elastic member is located between the first part and the second part. The first part can move relative to the second part.

[0062] The detection device is configured such that when the terminal of the connector abuts against the first part, the first part overcomes the elastic force of the elastic member under the force of the terminal and contacts the second part to verify that the terminal is conductive, and the first part fails to overcome the elastic force of the elastic member under the force of the terminal and contacts the second part to verify that the terminal is not conductive.

[0063] In such a detection device, an elastic member is provided between the first part and the second part, and the terminal of the connector overcomes the elastic force of the elastic member so that the first part and the second part are in contact and connected. Terminals that are not firmly installed cannot overcome the elastic force of the elastic member, that is, the first part and the second part cannot be connected, so the presence or absence of the terminal on the connector and the degree of firmness of the installation can be detected.

[0064] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the present application provides a detection device 100 for conducting a wire harness. The wire harness includes a connector. The detection device 100 includes a detection needle 10 and a base 20, and the detection needle 10 is arranged on the base 20.

[0065] The detection needle 10 includes an elastic member 101 , a first portion 102 and a second portion 103 . The elastic member 101 is located between the first portion 102 and the second portion 103 . The first portion 102 can move relative to the second portion 103 .

[0066] The detection device 100 is configured such that when the terminal 30 of the connector abuts against the first part 102, the first part 102 overcomes the elastic force of the elastic member 101 under the action of the terminal 30 and contacts the second part 103 to verify that the terminal 30 is conductive, and the first part 102 fails to overcome the elastic force of the elastic member 101 under the action of the terminal 30 and contacts the second part 103 to verify that the terminal 30 is not conductive.

[0067] In the above detection device 100, an elastic member 101 is provided between the first portion 102 and the second portion 103, and the terminal 30 of the connector overcomes the elastic force of the elastic member 101, so that the first portion 102 and the second portion 103 are in contact and conductive. The terminal 30 that is not firmly installed cannot overcome the elastic force of the elastic member 101, that is, the first portion 102 and the second portion 103 cannot be conductive, so the presence or absence of the terminal 30 on the connector and the degree of firmness of the installation can be detected.

[0068] Specifically, the wiring harness includes a connector and a wire. The connector includes a terminal 30, a secondary lock and a sheath. The wire is crimped with the terminal 30, inserted into the sheath, and loaded into the secondary lock.

[0069] The detection needle 10 is used to contact the terminal 30. The detection needle 10 includes a first part 102 and a second part 103. An elastic member 101 is provided between the first part 102 and the second part 103. The first part 102 can move relative to the second part 103. The first part 102 can conduct with the second part 103 when overcoming the elastic force of the elastic member 101.

[0070] The first portion 102 and the second portion 103 are made of conductive materials so that the first portion 102 and the second portion 103 can conduct electricity when in contact.

[0071] Optionally, the elastic member 101 may be connected to the first portion 102 and the second portion 103 . In this case, the elastic member 101 is made of a non-conductive material or is insulated to prevent the first portion 102 and the second portion 103 from conducting electricity without contact.

[0072] Optionally, the elastic member 101 may not contact the first portion 102 and the second portion 103. When the first portion 102 moves toward the second portion 103 under the action of the terminal 30, the first portion 102 contacts the elastic member 101, so that the elastic member 101 applies elastic force to the first portion 102. In this case, the elastic member 101 may be made of a conductive material.

[0073] In one embodiment, the elastic member 101 includes a spring disposed between the first portion 102 and the second portion 103 , which can provide elastic force to detect the firmness of the terminal 30 while not affecting the contact between the first portion 102 and the second portion 103 after overcoming the elastic force.

[0074] During the test, the connector is installed on the base 20, and the terminal 30 in the connector can contact the detection pin 10 on the base 20. At this time, the projections of the terminal 30, the first part 102 and the second part 103 in the vertical direction at least partially overlap, wherein the vertical direction is Figure 1 In the process of the terminal 30 contacting the detection pin 10 , the connector is pressed downward to make the terminal 30 contact the first part 102 and generate a downward force on the first part 102 .

[0075] The normally installed terminal 30 is fixed in the sheath, and the terminal 30 exerts a downward force on the first part 102, so that the first part 102 overcomes the elastic force of the elastic member 101 and contacts the second part 103. After the first part 102 and the second part 103 contact, the terminal 30, the first part 102 and the second part 103 are connected, that is, the terminal 30 can be normally connected.

[0076] However, the terminal 30 which is not firmly installed in the sheath may be separated from the sheath due to the reaction force of the elastic member 101 on the first part 102 after contacting the first part 102, or the first part 102 cannot overcome the elastic force and move toward the second part 103. In this way, the first part 102 is not in contact with the second part 103, that is, the terminal 30 cannot be normally conductive.

[0077] During the test, if the first part 102 and the second part 103 of the detection needle 10 are in contact, it means that the corresponding terminal 30 is conductive; if the first part 102 and the second part 103 of the detection needle 10 are not in contact, it means that the terminal 30 at the corresponding position of the connector is not installed or is not installed firmly.

[0078] One wiring harness may include one terminal 30 , or two or more terminals 30 .

[0079] In the case where there is only one terminal 30 inside the connector, the terminal 30 can be turned on, which means that the wiring harness can be turned on. In the case where the connector includes two or more terminals 30, each terminal 30 can be turned on, and the insertion order of the terminals 30 in the sheath is correct, which means that the wiring harness can be turned on.

[0080] In which, when all the terminals 30 are in contact with the detection needles 10 , the terminal device 200 connected to the testing apparatus can verify the insertion order of the terminals 30 in the sheath through relevant test logic.

[0081] According to some embodiments of the present application, the detection needle 10 further includes a shell 104 , and the second part 103 , the elastic member 101 and the first part 102 are sequentially mounted on the shell 104 , and the first part 102 is movable relative to the shell 104 .

[0082] The housing 104 is used to fix and install the first part 102, the elastic member 101 and the second part 103. In the vertical direction, the second part 103, the elastic member 101 and the first part 102 are sequentially installed in the housing 104. The second part 103 and the housing 104 are fixedly connected, and the first part 102 can move relative to the housing 104 and the second part 103. The first part 102 moves toward the second part 103 under the action of the terminal 30.

[0083] In the illustrated embodiment, the housing 104 is cylindrical and can limit the moving direction of the first portion 102 and the compression direction of the first portion 102 on the elastic member 101 , so that the first portion 102 moves toward the second portion 103 after receiving the force of the terminal 30 .

[0084] In the above technical solution, the shell 104 can be used to support and fix the first part 102, the elastic member 101 and the second part 103. The elastic member 101 isolates the first part 102 and the second part 103. The second part 103 and the elastic member 101 are fixed in the shell 104. The first part 102 is movable relative to the shell 104.

[0085] In this way, the shell 104 supports and fixes the elastic member 101 and the second part 103. When the terminal 30 of the connector contacts the first part 102, under the action of the terminal 30, the first part 102 moves relative to the shell 104 and the second part 103 until the first part 102 overcomes the elastic force of the elastic member 101 and contacts the second part 103. This indicates that the terminal 30 is firmly installed in the connector. Therefore, the presence or absence of the terminal 30 in the connector and the firmness of the installation of the terminal 30 can be detected.

[0086] See also Figure 1 According to some embodiments of the present application, the detection needle 10 further includes an insulating member 105 , which is disposed between the housing 104 and the second portion 103 so that the first portion 102 and the second portion 103 are not conductive when they are not in contact.

[0087] The insulating member 105 is used to insulate the second part 103 from the housing 104. When conducting a harness continuity test, the first part 102 and the second part 103 need to be connected only when the terminal 30 moves the first part 102 to connect with the second part 103. Therefore, it is necessary to avoid the first part 102 and the second part 103 being connected and connected through the housing 104 when they are not in contact.

[0088] Therefore, an insulating member 105 is provided between the second part 103 and the shell 104 to prevent the first part 102 and the second part 103 from being conductive when the terminal 30 is in contact with the first part 102 but the first part 102 and the second part 103 are not in contact, when one or both of the shell 104 and the elastic member 101 are conductive.

[0089] In one embodiment, the insulating member 105 includes a silicone ring, which is arranged on the second part 103 at the position where it is connected to the shell 104, and can insulate the shell 104 and the second part 103. At the same time, the silicone ring can increase the friction between the second part 103 and the shell 104, thereby fixing the second part 103 and the shell 104.

[0090] In the above technical solution, the insulating member 105 is disposed between the housing 104 and the second part 103, and is used to isolate the housing 104 from the second part 103, so as to prevent the first part 102 and the second part 103 from being conductive when the terminal 30 contacts the first part 102 but the first part 102 and the second part 103 are not in contact, when one or both of the housing 104 and the elastic member 101 are conductive. Providing the insulating member 105 between the housing 104 and the second part 103 can make the detection result more reliable.

[0091] See also Figure 2 and Figure 3According to some embodiments of the present application, the base 20 includes a detection sheet 201, the detection sheet 201 opens a detection channel 2011, the detection sheet 201 is arranged on the top of the detection needle 10, the top of the first part 102 corresponds to the position of the detection channel 2011, and the terminal 30 contacts the first part 102 through the detection channel 2011.

[0092] When the terminal 30 is installed on the sheath, the terminal 30 may be skewed on the sheath due to installation errors or structural defects of the terminal 30. A connector with such defects may cause poor contact during use, so it is necessary to detect the inclination of the terminal 30 on the sheath.

[0093] A detection sheet 201 is disposed on the top of the detection needle 10, and a detection channel 2011 is formed in the detection sheet 201. During the wiring harness continuity test, the connector contacts the detection sheet 201, and the terminal 30 extends into the detection channel 2011 and contacts the first portion 102 after passing through the detection channel 2011.

[0094] If the terminal 30 is skewed, it cannot extend into the detection channel 2011, or cannot contact the first part 102 through the detection channel 2011. Therefore, by providing the detection piece 201, the inclination of the terminal 30 on the sheath can be detected.

[0095] In the above technical solution, the terminal 30 contacts the first part 102 of the detection needle 10 after passing through the detection channel 2011. Setting the detection channel 2011 can detect whether the terminal 30 in the connector is tilted. If the probe installed in the connector is installed crookedly, it cannot pass through the detection channel 2011, thereby detecting the installation status of the terminal 30 in the connector.

[0096] According to some embodiments of the present application, the base 20 includes a locking mechanism 202 and a locking switch 203, which are arranged on the base 20, and the locking switch 203 is configured to enable the locking mechanism 202 to lock the connector on the base 20 when the terminal 30 contacts the first part 102 through the detection channel 2011.

[0097] The locking mechanism 202 and the locking switch 203 are used to lock the position of the connector on the detection device 100. After the connector is installed on the base 20, the locking switch 203 is triggered. After the locking switch 203 is triggered, the locking mechanism 202 is activated to lock the connector on the base 20. In this way, the contact between the connector and the detection needle 10 can be stable, so as to obtain accurate test results.

[0098] In the above technical solution, the locking mechanism 202 is used to lock the connector on the base 20. After the connector is installed on the detection device 100, the locking switch 203 is triggered. The locking switch 203 can enable the locking mechanism 202 to fix the connector on the base 20 to avoid unstable connection between the connector and the detection needle 10 and affect the test results.

[0099] According to some embodiments of the present application, the locking mechanism 202 includes a locking plate (not shown). When the locking switch 203 triggers the locking mechanism 202 , the locking plate extends and abuts against the connector to lock the connector to the base 20 .

[0100] The locking mechanism 202 includes a locking piece, and the locking switch 203 is in transmission connection with the locking piece. When the connector is mounted to the base 20 and the locking switch 203 is triggered, the locking piece can extend from the locking mechanism 202 and abut against the parallel connector, thereby fixing the connector on the base 20.

[0101] In one embodiment, the locking mechanism 202 includes a switch rod and a locking plate, the switch rod is connected to the locking plate, and the switch rod is used to drive the locking plate to switch between a locked position and an unlocked position. The locking switch 203 is connected to the switch rod in a transmission manner. After the locking switch 203 is triggered, the switch rod drives the locking plate to extend and press against the upper surface of the connector, thereby fixing the connector on the base 20.

[0102] In one embodiment, the locking piece is telescopically arranged on the locking mechanism 202, and the locking switch 203 is drivingly connected to the locking piece. When the locking switch 203 is pressed down, the locking piece pops out to lock the connector.

[0103] In the above technical solution, the locking mechanism 202 fixes the connector to the base 20 through the locking piece. After the connector is installed on the detection device 100, the locking switch 203 is triggered to control the locking piece of the locking mechanism 202 to extend and fix the connector to the base 20. The locking piece presses against the connector to fix it, so that the locking mechanism 202 can reliably fix the connector.

[0104] According to some embodiments of the present application, the locking mechanism 202 is configured to unlock the connector and the base 20 upon receiving an unlocking signal.

[0105] The detection device 100 is electrically connected to the detection machine, and the detection machine detects the detection parameters after the wiring harness is turned on. If the wiring harness is qualified, the detection machine sends an unlocking signal, and the locking mechanism 202 unlocks the connector and the base 20 when receiving the unlocking signal. If the wiring harness is unqualified, the tester needs to make a second confirmation before sending the unlocking signal, so as to avoid the leakage of defective products.

[0106] In one embodiment, the locking mechanism 202 includes a switch rod and a locking plate, the switch rod is connected to the locking plate, and the switch rod is used to drive the locking plate to switch between a locked position and an unlocked position. The locking switch 203 is connected to the switch rod in a transmission manner. After the locking switch 203 is triggered, the switch rod drives the locking plate to extend and press against the upper surface of the connector, thereby fixing the connector on the base 20.

[0107] The locking mechanism 202 also includes a driving member, which is electrically connected to the test member. When receiving an unlocking signal, the driving member drives the switch rod to retract the locking piece to contact and lock the connector.

[0108] In one embodiment, when the test result is unqualified, the locking mechanism 202 will not be automatically unlocked, and the connector cannot be removed. A dedicated person needs to enter a password in the terminal device 200 before sending an unlocking command, thereby preventing defective products from being missed and outflowed.

[0109] In the above technical solution, when the wire harness is tested to be qualified, the tester sends an unlocking signal. When receiving the unlocking signal, the locking mechanism 202 releases the lock on the connector, so that the tester can remove the wire harness from the test device 100 .

[0110] When the detection machine does not send an unlocking signal, the locking mechanism 202 remains locked so that the wiring harness that fails the detection cannot be removed, thereby preventing the occurrence of false detection and missed detection.

[0111] See also Figure 2 According to some embodiments of the present application, the connector has a first positioning portion (not shown), and the base 20 includes a second positioning portion 204 corresponding to the shape of the first positioning portion. When the first positioning portion and the second positioning portion 204 are positioned and connected to each other, the terminal 30 contacts the first part 102 through the detection channel 2011.

[0112] During the assembly of the wire harness, the sheath may be misused or installed in the wrong direction. The connector includes a sheath, which includes a first positioning portion. According to the shape of the first positioning portion, a second positioning portion 204 corresponding to the shape of the first positioning portion is provided on the base 20.

[0113] Only when the positions of the first positioning portion and the second positioning portion 204 correspond to each other, the connector can be successfully installed on the base 20 , so that it can be checked whether the sheath of the wiring harness is used incorrectly and whether the installation direction of the sheath is correct.

[0114] In one embodiment, the second positioning portion 204 includes a contoured portion corresponding to the outer structure of the connector sheath, and is manufactured according to the outer structure of the connector sheath so that an incorrect connector cannot be inserted, and incorrect use of the connector sheath can be detected.

[0115] Optionally, the first positioning portion includes a protrusion on the sleeve, and the second positioning portion 204 includes a groove opened in the base 20 .

[0116] In the above technical solution, the connector has a first positioning portion, and a second positioning portion 204 matching the shape of the first positioning portion is provided on the base 20. Therefore, the connector can be installed on the base 20 only when the first positioning portion and the second positioning portion 204 are positioned and connected to each other. By providing the second positioning portion 204 on the base 20, it is possible to check whether the sheath of the wiring harness is used incorrectly and whether the installation direction of the sheath is correct.

[0117] See also Figure 2 According to some embodiments of the present application, the connector includes a secondary lock, the detection device 100 includes a first detection switch 205, the first detection switch 205 is arranged on the base 20, and the first detection switch 205 is configured to trigger the secondary lock in place signal when the secondary lock conflicts with the first detection switch 205.

[0118] The base 20 of the detection device 100 is provided with a first detection switch 205, and the position of the first detection switch 205 is set at a position where the secondary lock on the connector can contact when the connector is installed on the base 20. If the secondary lock is not installed on the sheath, the first detection switch 205 cannot be triggered, so that it can be detected whether the secondary lock is missing.

[0119] In the above technical solution, the connector includes a secondary lock, and a first detection switch 205 is provided on the base 20. After the connector is installed on the base 20, the position of the secondary lock can touch the first detection switch 205. After the first detection switch 205 is triggered, a signal indicating that the secondary lock is in place can be issued, indicating that the secondary lock has been installed in the connector. In this way, the installation status of the secondary lock in the connector of the wiring harness can be detected.

[0120] According to some embodiments of the present application, the connector includes a sealing ring, the detection device 100 includes a second detection switch, the second detection switch is arranged on the base 20, and the second detection switch is configured to trigger the sealing ring in-place signal when the sealing ring contacts the second detection switch.

[0121] The base 20 of the detection device 100 is provided with a second detection switch, and the position of the second detection switch is set at a position where the sealing ring on the connector can contact when the connector is installed on the base 20. If the sealing ring is not installed on the sheath, the second detection switch cannot be triggered, so that it can be detected whether the secondary lock is missing.

[0122] Optionally, the first detection switch 205 and the second detection switch include micro switches. The micro switches are electrically connected to the terminal device 200. When a corresponding component on the connector triggers the micro switches, the terminal device 200 can receive a presence signal of the corresponding component.

[0123] In the above technical solution, the connector includes a sealing ring, and a second detection switch is provided on the base 20. After the connector is installed on the base 20, the position of the sealing ring can touch the second detection switch. After the second detection switch is triggered, a sealing ring in-place signal can be issued, indicating that the sealing ring has been installed in this connector. In this way, the installation status of the sealing ring in the connector of the wiring harness can be detected.

[0124] According to some embodiments of the present application, the detection device 100 includes a fastener (not shown), and the base 20 is fixedly connected to the workbench via the fastener.

[0125] The detection device 100 can be installed on a workbench to facilitate the tester to perform the detection operation. The detection device 100 is installed by fasteners, so that the detection device 100 can be installed firmly and reliably and is easy to use.

[0126] In the above technical solution, the base 20 is fixed on the workbench by fasteners. When testing the wiring harness, the detection device 100 needs to be connected to the detection machine. At the same time, the detection device 100 needs to plug and unplug the connectors of multiple wiring harnesses and the detection device 100. The use of fasteners for fixing can stabilize the position of the detection device 100 and facilitate detection.

[0127] Second, see Figure 4 , the present application provides a detection device 1000. The detection device 1000 includes the detection apparatus 100 of any of the above embodiments.

[0128] In the above detection device 1000, an elastic member 101 is provided between the first part 102 and the second part 103, and the terminal 30 of the connector overcomes the elastic force of the elastic member 101, so that the first part 102 and the second part 103 are in contact and connected. The terminal 30 that is not firmly installed cannot overcome the elastic force of the elastic member 101, that is, the first part 102 and the second part 103 cannot be connected, so the presence or absence of the terminal 30 on the connector and the degree of firmness of the installation can be detected.

[0129] Specifically, the detection device 1000 includes a detection apparatus 100, a terminal device 200, and a workbench, and the detection apparatus 100 and the terminal device 200 can be installed on the workbench.
