[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0054] The present application embodiment provides a connector detection device, such as Figure 1 As shown, it specifically includes the following components:

[0055] Handle, probe and probe.

[0056] The handle comprises a hollow handle body and a spring arranged inside the handle body, that is, the center of the handle body is hollow so that the spring can be arranged therein.

[0057] Optionally, since the spring is usually cylindrical, the hollow shape of the handle body can also be a cylinder, and its diameter is preferably only slightly larger than the diameter of the spring, which can effectively ensure that the spring is inside the handle body without shaking and affecting the detection results.

[0058] One end of the probe is connected to one end of the spring inside the handle body through an opening at one end of the handle body, that is, an opening is provided at one end of the handle body so that the probe can be connected to the spring inside the handle body through the opening, thereby compressing the spring through the probe. Therefore, the diameter of the opening needs to be larger than the diameter of the probe so that the probe can contact the internal spring through the opening and can move to the inside of the handle body during detection.

[0059] Optionally, the probe and the spring may be connected by just contacting each other without being fixed together, as long as the diameter of the probe is not less than the diameter of the spring, the spring can be compressed when the probe moves toward the handle. Of course, they may also be directly fixedly connected.

[0060] In addition, a thrust scale is provided on the surface of the probe rod so as to determine the magnitude of the thrust.

[0061] Specifically, the scale value corresponding to the cross section of one end of the opening of the handle body is the current thrust magnitude, so the thrust scale value becomes larger the farther away from the handle body.

[0062] Optionally, the thrust scale is usually set to ensure that when no test is performed, that is, when the connector detection device is not subjected to force, the cross section of one end of the handle body opening is in the same plane as the zero scale line. The subsequent scale settings need to be set based on the elastic coefficient of the spring.

[0063] One end of the probe is connected to the other end of the probe column. When the connector is tested, the other end of the probe is pressed against the plug terminal of the connector. Then, a thrust toward the connector can be applied to the connector testing device through the handle body, so that the plug terminal of the connector is subjected to the thrust through the probe and can be tested.

[0064] Optionally, since the diameter of the probe is relatively small, it is necessary to select a material with relatively high strength, usually a metal material, and different metal probes can be used for different connectors.

[0065] The embodiment of the present application provides a connector detection device, including a handle, a probe column and a probe. The handle includes a hollow handle body and a spring arranged inside the handle body. One end of the probe column is connected to one end of the spring inside the handle body through an opening at one end of the handle body, and a thrust scale is arranged on the surface of the probe column. One end of the probe is connected to the other end of the probe column, and the other end of the probe is pressed against the plug terminal of the connector when the connector is detected. Therefore, when the connector is detected, the probe is pressed against each plug terminal of the connector at the same time, and then a thrust is applied. At this time, the probe column will compress the spring to retract, and the thrust scale on the probe column can be used to determine the current applied thrust accordingly, so that the thrust corresponding to the connector can be accurately used to quickly and accurately measure each terminal of the connector.

[0066] Optionally, in another embodiment of the present application, the connector detection device may further include:

[0067] Adjustable stop.

[0068] The adjustable limiter is arranged on the probe column, and its position is adjustable, and is used to limit the probe column from moving in the direction of the handle, and the maximum movement is to the adjustable limiter contacting the handle body.

[0069] Since a specified thrust is applied to the connector detection device during the detection process, in order to quickly apply an accurate thrust, improve the test efficiency, and avoid applying a thrust that is too large or too small, an adjustable limiter is provided on the probe column in an embodiment of the present application, and its position on the probe column can be adjusted according to the thrust to be applied, so that when the corresponding thrust is applied during the test, the probe column cannot continue to move in the direction of the handle, that is, the main function of the limiter is to jam the probe column so that it can no longer move in the direction of the handle.

[0070] Therefore, the maximum distance between the edge of the adjustable limiter and the center line of the probe column needs to be greater than the radius of the opening set on the handle body, so that when the probe column moves to the adjustable limiter and contacts the handle body, the adjustable limiter cannot pass through the opening on the handle body and cannot move further.

[0071] Alternatively, if Figure 2 As shown, in order to ensure that the adjustable limiter is subjected to a more uniform force when in contact with the handle body, thereby avoiding detection errors and preventing the adjustable limiter from being easily damaged, the adjustable limiter can be in a ring shape, which can be put on the probe column and has an adjustable position.

[0072] For example, a ring, sleeve, etc. that can be adjusted in tightness or has elasticity can be used as an adjustable limiter, so that its position on the probe column can be adjusted by adjusting the tightness.

[0073] Optionally, in a connector detection device provided in another embodiment of the present application, Figure 3 As shown, the probe column in the connector detection device provided in the embodiment of the present application includes:

[0074] A threaded portion having threads on its surface and a scale portion having thrust scales on its surface.

[0075] Among them, the threaded part is one end of the probe connection, and the thread on its surface is used to set and adjust the adjustable limiter. That is, by setting the thread on the surface of the threaded part in the embodiment of the present application, the adjustable limiter can be set by falling into place, and when adjusting the position by the thread, it only needs to be adjusted to the required position, and it can be fixed, and there is no need to fix the position of the adjustable limiter, which is more convenient.

[0076] The scale portion is an end connected to the spring inside the handle body.

[0077] The diameter of the threaded portion is greater than the diameter of the scale portion, so that the adjustable limiter arranged on the threaded portion can extend to the scale portion.

[0078] Correspondingly, see also Figure 3 In the embodiment of the present application, the adjustable limiter is a cylinder with an internal thread, which is sleeved on the outside of the probe column through the threaded portion of the probe column, and its position is adjusted by rotation, that is, the threaded portion of the probe column is equivalent to a bolt, and the adjustable limiter is equivalent to a nut.

[0079] The outer diameter of the adjustable stopper is larger than the diameter of the opening of the handle body, so that it can play a role of limiting. In addition, the adjustable stopper can at least adjust the cross section of the end closer to the handle from the maximum scale position to the minimum scale position on the surface of the scale part of the probe column. Since the cross section of the end of the adjustable stopper closer to the handle is the cross section that plays a role of limiting, it should be ensured that it can be limited to the maximum scale and the minimum scale, so that each scale can be limited.

[0080] Another embodiment of the present application provides another connector detection device, such as Figure 4 As shown, including:

[0081] Handle, probe, probe, adjustable limit stop.

[0082] The handle comprises a hollow handle body and a spring arranged inside the handle body.

[0083] like Figure 4 As shown, the handle body is a cylinder with an opening at one end and a bottom cover at the other end, so that the spring can be replaced by removing the bottom cover. The handle is cylindrical in shape, which is also convenient for using the connector detection device.

[0084] In addition, the diameter of the opening arranged at one end of the handle body is smaller than the diameter of the spring arranged inside the handle body, so as to prevent the spring from falling from the opening.

[0085] The probe column comprises a probe column body and a disc arranged at one end of the probe column body.

[0086] The disc is inside the handle body and connected to one end of the spring inside the handle body. Its diameter is larger than the diameter of the opening on the handle body, so that the probe can be clamped to prevent it from falling out of the opening. In addition, the disc can evenly transfer the reverse force of the connector received by the probe to the spring, and does not need to be fixedly connected to the spring, making it more convenient to replace the spring.

[0087] A thrust scale is provided on the surface of the probe.

[0088] In the embodiment of the present application, the probe comprises a metal probe rod and a metal probe ball connected to one end of the metal probe rod.

[0089] Among them, when the metal probe catches up with the end provided with the metal probe ball, it presses against the plug terminal of the connector when testing the connector. The metal probe ball can more effectively contact the terminals of the connector at the same time and perform testing, and also avoid damage to the terminals.

[0090] The other end of the metal probe rod is connected to the probe column by a detachable connection method, so that the probe can be replaced according to needs, for example, it can be connected by means of threads or snaps.

[0091] Optionally, in another embodiment of the present application, in order to achieve the connection between the metal probe rod and the probe column, it further includes:

[0092] A column connector used to connect the metal probe rod to the probe column.

[0093] Specifically, Figure 5 As shown, one end of the column connector is fixed on the probe column, and the other end is provided with a hole groove with a diameter larger than the metal probe rod, and a screw connecting the hole groove is provided in the perpendicular direction of the center line of the hole groove, which is used to fix or remove the metal probe rod inserted into the hole groove.

[0094] like Figure 4 As shown, the adjustable limiter is arranged on the probe column, and its position is adjustable, and is used to limit the probe column to move in the direction of the handle, and the maximum movement is to the adjustable limiter contacting the handle body.

[0095] Based on the connector detection device provided above, the embodiment of the present application provides a connector detection method, such as Figure 6 As shown, including:

[0096] S601. Determine a detection thrust value of the connector to be detected according to the type of the connector to be detected.

[0097] Since different types of connectors have different uses and materials, the pressures they are required to withstand during testing are also different. Therefore, the testing thrust values ​​corresponding to each type of connector can be pre-configured. When the connector to be tested needs to be tested, the testing thrust value of the connector to be tested is determined.

[0098] S602: Align one end of the probe of the connector detection device to the plug terminal of the connector to be detected.

[0099] The other end of the probe of the connector detection device is connected to the probe column of the connector detection device, and the other end of the probe column is connected to the spring arranged inside the handle body through the opening at one end of the hollow handle body included in the handle of the connector detection device.

[0100] S603, gradually applying a thrust toward the connector to be detected to the connector detection device until the cross section of the end of the handle body provided with the opening reaches the scale line corresponding to the detection thrust value of the connector to be detected on the probe column.

[0101] It should be noted that when no thrust is applied, the zero scale line on the probe is exactly on the same plane as the cross section of the end of the handle body with the opening. When the thrust begins to be applied, the probe compresses the spring and continuously retracts into the handle body, and the scale value on the probe that is aligned with the cross section of the end of the handle body with the opening also changes continuously. When it changes to the scale line corresponding to the thrust value of the connector to be tested, it means that the thrust applied at this time is exactly the thrust value of the connector to be tested.

[0102] In order to avoid applying a thrust greater than the detection thrust value of the connector to be detected, thereby damaging the connector to be detected and failing to accurately determine the detection result, and also to speed up the detection efficiency, in another embodiment of the present application, after step S601, further comprising:

[0103] Adjust the adjustable stopper of the connector detection device to a cross section at the end closer to the handle so that the scale line corresponding to the detection thrust value of the connector to be detected is on the same plane;

[0104] The adjustable stopper is a part that can be adjusted in position and is used to limit the movement of the probe rod toward the handle. When the probe rod moves to the point where the adjustable stopper contacts the handle, the probe rod will be stopped and continue to move, so that the thrust to be applied can be quickly determined.

[0105] Therefore, accordingly, in the embodiment of the present application, a specific implementation of step S603 includes:

[0106] A pushing force is gradually applied to the connector detection device toward the connector to be detected until the adjustable stopper of the connector detection device contacts the handle.

[0107] S604: Detect whether the plug terminal of the connector to be detected is shrunk before and after the detection.

[0108] If it is detected that the plug terminal of the connector to be tested shrinks before and after the test, it means that after receiving the corresponding test thrust value, it fails to effectively withstand the thrust, thereby causing shrinkage, and shrinkage will cause connection problems, so step S605 is executed at this time. Correspondingly, if it is detected that the plug terminal of the connector to be tested does not shrink before and after the test, it means that the terminal of the connector to be tested effectively withstands the corresponding thrust, so step S606 is executed at this time.

[0109] S605: Determine that the connector to be tested is unqualified.

[0110] S606: Determine whether the connector to be tested is qualified.
