Description

Technical Field

[0001] This application relates to the field of motor manufacturing equipment, and more particularly to a plug-in power-on testing device. Background Technology

[0002] The wiper motor is the driving component of the wiper. During the production process, the wiper motor needs to be tested by power supply at the manual work station. In the existing testing method, the wiper motor plug is usually inserted into the test socket. The test socket is equipped with a metal elastic contact plate. The elastic contact plate contacts the pin of the plug to realize the electrical connection between the plug and the test socket. This testing method has the following problems: (1) When the elastic contact plate in the test socket is used more than 200 times, it often becomes loose or worn, resulting in poor contact between the pin of the plug and the elastic contact plate, which affects the electrical test effect; (2) The test socket is severely worn and cannot realize the quick replacement function. Utility Model Content

[0003] This application provides a plug-in power-on testing device that can significantly increase the number of tests and lifespan.

[0004] This embodiment provides a plug-in power-on testing device, including a housing, a locking tongue, an elastic element, a guide sleeve, and a telescopic probe. The locking tongue is hinged to the housing and can rotate relative to the housing in a first direction. One end of the locking tongue is provided with a locking tongue portion, and a limiting space is formed between the locking tongue portion and the housing to restrict the movement of the product in a second direction. The two ends of the elastic element abut against the housing and the locking tongue respectively, and the axial direction of the elastic element is configured in a third direction, with the first direction, the second direction, and the third direction intersecting each other. The guide sleeve is provided on one side of the housing facing the product, and the product's plug is provided with a guide groove for sliding cooperation with the guide sleeve, allowing the guide sleeve to be inserted into the guide groove in a second direction. The telescopic probe is provided on the guide sleeve and can contact and abut against a pin provided in the guide groove in a second direction.

[0005] The plug-in power-on testing device of this application has at least the following beneficial effects:

[0006] The plug-in electrical testing device of this application includes a housing, a locking tongue, an elastic element, a guide sleeve, and a telescopic probe. When testing is required, the elastic element is compressed, causing the locking tongue to rotate and tilt away from the guide sleeve. Then, the guide sleeve is inserted into the product's connector along a second direction. After the locking tongue is released, the elastic element drives the locking tongue to move towards the connector, causing at least a portion of the connector's structure to be located between the locking tongue and the housing. The locking tongue and housing prevent the connector from disengaging from the guide sleeve along the second direction, ensuring the stability of the electrical test. Simultaneously, when the guide sleeve is inserted into the connector, the telescopic probe on the guide sleeve and the connector's pin elastically abut against each other in the second direction, thereby achieving electrical connection. In this application, the relative movement direction of the pin and the telescopic probe is consistent with the telescopic probe's extension direction. In contrast, in the prior art, the downward pressing direction of the elastic contact plate is not consistent with the movement direction of the pin, which easily causes fatigue of the elastic contact plate. The design of this application can effectively increase the number of uses of the testing device and improve production efficiency. Attached Figure Description

[0022] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0024] like Figure 1 and Figure 2 As shown, this embodiment discloses a plug-in power-on testing device, including a housing 100, a locking tongue 200, an elastic element 300, a guide sleeve 400, and a telescopic probe 500;

[0025] like Figure 1As shown, the interior of the outer casing 100 is a hollow structure and is made entirely of insulating material. A downwardly recessed receiving groove 110 is provided on the top surface of the outer casing 100. The receiving groove 110 is used to accommodate at least a portion of the latch 200. The latch 200 is hinged to the outer casing 100 and can rotate relative to the outer casing 100 about a first direction. In this embodiment, a hinge shaft 120 is provided within the receiving groove 110. The axial direction of the hinge shaft 120 is configured in the first direction. The latch 200 passes through the hinge shaft 120 along the first direction, allowing the latch 200 to rotate relative to the outer casing 100 about the hinge shaft 120.

[0026] like Figure 1 As shown, the locking tongue 200 has a locking tongue portion 210 at its front end in the second direction. A limiting space (denoted as M) is formed between the locking tongue portion 210 and the front end face 130 of the housing 100 to limit the product under test (specifically, the product's docking plug 600). Specifically, it can limit the docking plug 600 from disengaging from the device of this embodiment in the second direction.

[0027] like Figure 3 and Figure 4 As shown, in some preferred embodiments, the latch 200 includes a latch portion 210, a rod portion 220, and a push portion 230 connected in sequence along the second direction; along the second direction, the latch portion 210 is located in front of the housing 100, the rod portion 220 is disposed in the receiving groove 110 and is penetrated by the hinge shaft 120, the push portion 230 is disposed on the rod portion 220 and is located at the end away from the latch portion 210, and the push portion 230 and the rod portion 220 are connected to form an L-shaped structure. In this embodiment, the elastic element 300 (such as a spring or other elastic structure) is disposed on the housing. One end of the elastic element 300 abuts against the rod 220 of the locking tongue 200, and the other end of the elastic element 300 abuts against the outer shell 100. The extension and retraction direction of the elastic element 300 is configured as the third direction. The elastic force of the elastic element 300 causes the rod 220 to have a tendency to drive the locking tongue 210 to rotate downward, so as to ensure that the docking plug 600 will not disengage from the limiting space M during the electrical testing process. When it is necessary to release the docking plug 600, the operator only needs to push the push part 230 to make the rod 220 overcome the elastic force of the elastic element 300 and drive the locking tongue 210 to rotate, thereby releasing the docking plug 600 and disengaging it from the device of this embodiment.

[0028] In this embodiment, the first direction, the second direction, and the third direction intersect each other perpendicularly, and the third direction is configured as the height direction.

[0029] like Figure 3As shown, in some preferred embodiments, along the second direction, the locking tongue 210 is configured with a first inclined surface 211 on one side away from the housing 100. The first inclined surface 211 has an angle of less than 90 degrees with respect to the second direction. The docking plug 600 is provided with a second inclined surface 620. In the second direction, the first inclined surface 211 can fit and slide relative to the second inclined surface 620 (i.e., wedge fit). In this way, when the product needs to be tested, the second inclined surface 620 of the docking plug 600 is oriented towards the first inclined surface 211, and the docking plug 600 is moved towards the housing 100 along the second direction. The second inclined surface 620 can slide with the first inclined surface 211 and lift the locking tongue 210 upward. After the first inclined surface 211 of the locking tongue 210 passes the second inclined surface 620, the locking tongue 210 can hook the top structure of the docking plug 600 and limit the docking plug 600.

[0030] In some preferred embodiments, such as Figure 3 As shown, along the second direction, the latch 200 is provided with a vertical surface 212 facing one inner side of the housing 100. This vertical surface 212 is parallel to the third direction and also perpendicular to the second direction. The vertical surface 212 and the front end face 130 of the housing 100 form the limiting space M. In this embodiment, by blocking the movement of the mating plug 600 in the second direction with two surfaces, the mating plug 600 can be prevented from accidentally disengaging during the test, thereby enabling the test to be carried out effectively.

[0031] In some preferred embodiments, such as Figure 3 and Figure 5 As shown, the latch 200 is provided with a through threaded hole 221, and a limit bolt 240 is provided in the threaded hole 221. The limit bolt 240 can abut against the outer casing 100, thereby limiting the minimum included angle of the latch 200 relative to the second direction (e.g., Figure 5 As shown in θ), specifically, the rod portion 220 of the latch 200 is provided with a threaded hole 221, and the limiting bolt 240 is threadedly connected to the threaded hole 221. When the rod portion 220 rotates downward, the lower end of the limiting bolt 240 can abut against the outer shell 100, thereby restricting the rod portion 220 from continuing to rotate downward. That is, in this embodiment, the position of the latch portion 210 can be adjusted according to the actual situation, that is, the angle of the rod portion 220 relative to the second direction can be adjusted, which can make it easier for the plug 600 to approach the outer shell 100 with less resistance. The position of the latch portion 210 can also be adjusted according to the angle of the first inclined surface 211 of different specifications.

[0032] like Figure 3 and Figure 4As shown, the guide sleeve 400 is disposed on one side of the housing 100 facing the product. Specifically, along the second direction, the guide sleeve 400 is disposed on one side of the housing 100 facing the docking plug 600, and the guide sleeve 400 extends away from the housing 100 along the second direction. The docking plug 600 is provided with a guide groove 610, which is opened along the second direction. The size and shape of the guide groove 610 match the guide sleeve 400, and the guide groove 610 and the guide sleeve 400 can slide and engage in the second direction. In this embodiment, by setting the guide sleeve 400 and the guide groove 610 to engage, the docking accuracy and stability of the docking plug 600 and the telescopic probe 500 can be improved. At the same time, the guide sleeve 400 restricts the degree of freedom of the docking plug 600 other than the second direction to ensure the stable operation of electrical testing. In some preferred embodiments, the guide sleeve 400 and the housing 100 are detachably connected. The detachable connection method is such as screw connection, magnetic connection, etc., which is not limited here. The guide sleeve 400 is detachable and can be easily replaced according to different specifications of the docking plug 600, improving the flexibility of the device.

[0033] like Figure 3 As shown, the telescopic probe 500 is disposed on the guide sleeve 400, and the guide groove 610 of the docking plug 600 is provided with a pin 630. The pin 630 extends at least part of its structure into the guide groove 610 along the second direction. When the guide sleeve 400 is inserted into the guide groove 610 along the second direction, the telescopic probe 500 on the guide sleeve 400 can elastically abut against the pin 630 in the second direction and achieve electrical connection. In this embodiment, the electrical connection between the telescopic probe 500 and the ejector pin 630 differs from that in the prior art. The prior art uses an elastic contact plate to press down on the ejector pin, thus achieving an electrical connection between the ejector pin and the elastic contact plate. However, after a certain number of tests, this method leads to fatigue of the elastic contact plate, resulting in poor contact. In this embodiment, since the telescopic direction of the telescopic probe 500 is consistent with the extension direction (i.e., the length direction) of the ejector pin 630, even if the telescopic probe 500 experiences elastic fatigue, at most the reset force or the extension displacement will be slightly reduced, without causing poor contact. This significantly improves the number of uses and lifespan of the device. The specific structure of the telescopic probe 500 can be referenced from existing structures and will not be described in detail here.

[0034] In some preferred embodiments, such as Figure 3 As shown, the guide sleeve 400 is provided with a through hole 410, which is opened along the second direction. The telescopic probe 500 is coaxially disposed in the through hole 410. The design of the through hole 410 can effectively protect the telescopic probe 500. The tail end of the telescopic probe 500 extends into the interior of the housing 100 and is electrically connected to an external cable disposed inside. The external cable is electrically connected to an external test device to facilitate electrical testing.

[0035] like Figure 6 As shown, when the guide sleeve 400 is inserted into the guide groove 610, the ejector pin 630 can be inserted into the through hole 410 and elastically abut against the telescopic probe 500 in the through hole 410. Since the guide sleeve 400 and the guide groove 610 are in clearance fit, the ejector pin 630 and the guide sleeve 400 will not have relative movement in other directions except for relative movement in the second direction, thus effectively preventing the ejector pin from breaking.

[0036] In some preferred embodiments, such as Figure 3 As shown, a waterproof connector 700 is threaded onto the side of the housing 100 opposite to the guide sleeve 400. An external cable passes through the waterproof connector 700 and is electrically connected to the telescopic probe 500. The waterproof connector 700 can be tightened with a nut to prevent the cable from being pulled outward and to prevent the telescopic probe 500 from being stretched.

[0037] One working principle of the plug-in power-on test device in this embodiment is as follows: Figure 6 As shown, Figure 6 (A) shows a diagram where the connector is not plugged into the test device, and (B) shows a diagram where the connector is plugged into the test device.

[0038] 1. The second inclined surface 620 of the docking plug 600 is oriented toward the outer shell 100, and the docking plug 600 is moved toward the outer shell 100 in the second direction. During the movement of the docking plug 600 toward the outer shell 100, the second inclined surface 620 pushes the locking tongue 210 upward. After the locking tongue 210 passes the second inclined surface 620, it is driven by the elastic element 300 and locks the top structure of the docking plug 600 downward. At the same time, the guide sleeve 400 is inserted into the guide groove 610 of the docking plug 600.

[0039] 2. The telescopic probe 500 inside the guide sleeve 400 abuts against the ejector pin 630 inside the guide groove 610 in the second direction, thereby achieving an electrical connection between the two. External equipment can be electrically connected to the docking plug 600 through the telescopic probe 500 to perform electrical testing.

[0040] 3. After the electrical test is completed, the staff manually pushes the pusher 230, so that the locking tongue 210 is lifted upward relative to the docking plug 600, and the docking plug 600 can then disengage from the guide sleeve 400 in the second direction. After disengagement, the staff releases the pusher 230, and the locking tongue 210 returns to its initial position under the action of the elastic element 300.

[0041] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
