Description

Technical Field

[0001] This utility model relates to a testing fixture, specifically, to a product testing fixture with a plug. Background Technology

[0002] When using traditional product testing fixtures with plugs, operators usually need to directly plug the socket 2 on the product into the fixture's plug, and then turn on the power to perform the test, thereby checking whether the internal circuitry of the product can be used normally.

[0003] Existing fixtures often lack an effective verification mechanism for the plug's insertion status when testing products with plugs. Operators can only make a rough judgment by touch or visual inspection, making it difficult to accurately determine whether the socket 2 and the plug are fully inserted. If there is a loose connection or incomplete insertion, short circuits or open circuits in the wiring connection are likely to occur, which will directly lead to misjudgments in subsequent power-on test results. This can result in qualified products being mistakenly identified as defective products, causing waste of production and reducing the accuracy and reliability of the test. Utility Model Content

[0004] The purpose of this utility model is to provide a product testing fixture with a plug to solve the problems mentioned in the background art above:

[0005] Operators cannot accurately determine whether the socket and plug are fully plugged in by touch or sight alone. If there is a loose connection or incomplete insertion, it will directly lead to misjudgment of the subsequent power-on test results.

[0006] To address the above problems, this utility model aims to provide a product testing fixture with plugs, including a housing. The housing has a vertically extending assembly groove. Two plugs are symmetrically mounted on the top of the assembly groove via a pivot. Each plug has an arc-shaped groove on its side closest to the other. An infrared transmitter, an infrared receiver, and an indicator light are fixedly mounted on the upper sidewall of the housing. The infrared transmitter and receiver are respectively located on opposite sides of the plugs. The indicator light is electrically connected to the infrared receiver. A locking mechanism is provided inside the assembly groove. When both plugs are perpendicular to the upper surface of the housing, the locking mechanism fixes the plugs' positions. At this time, the two arc-shaped grooves together form a light-transmitting hole. The light emitted by the infrared transmitter passes through the light-transmitting hole and is received by the infrared receiver. When a socket is plugged into the two plugs, if the socket is properly inserted, it blocks the light-transmitting hole. In this case, the infrared receiver cannot receive the light emitted by the infrared transmitter, triggering the indicator light to illuminate.

[0007] As a further improvement to this technical solution, the locking mechanism includes two half gears that are respectively fixedly installed on the two plugs. The axis of the half gears is collinear with the axis of the rotating shaft. A rack is horizontally slidably arranged inside the assembly groove at a position corresponding to each half gear, and the rack meshes with the corresponding half gear.

[0008] As a further improvement to this technical solution, a guide groove is provided on the rack, and a T-shaped positioning block is slidably installed inside the guide groove. The T-shaped positioning block is fixedly installed on the inner wall of the assembly groove.

[0009] As a further improvement to this technical solution, when the plug is in a state perpendicular to the upper surface of the housing, the end of the rack away from the center of the housing contacts the inner wall of the assembly groove. When the plug rotates outward around the axis to an inclined state, the inner wall of the guide groove away from the center of the housing contacts the T-shaped positioning block.

[0010] As a further improvement to this technical solution, the locking mechanism also includes a stop block disposed between the two racks. One end of the stop block slides through the housing and extends outward. When the plug is in a state perpendicular to the upper surface of the housing, the ends of the two racks that are close to each other contact the two sides of the stop block respectively.

[0011] As a further improvement to this technical solution, a protrusion is fixedly installed on the upper side wall of the block at a position outside the housing, and a limiting plate is fixedly installed on one side of the housing by a bracket, with the limiting plate located on the side of the block away from the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This product testing fixture with plugs features an infrared transmitter and receiver, along with a light-transmitting hole formed by the arc-shaped grooves on the two plugs. When the socket is properly inserted, the light-transmitting hole is blocked, preventing the infrared receiver from receiving the light emitted by the infrared transmitter. This triggers an indicator light, visually indicating to the operator that the socket and plug are properly inserted and subsequent testing can proceed. If the indicator light does not illuminate, it indicates that the insertion is not complete and needs to be checked and re-inserted. This avoids false detections due to poor insertion and improves testing reliability.

[0014] 2. When cleaning dust from the inner wall of the arc-shaped groove of this product testing fixture with a plug, the operator can first move the stop block to release the rack, causing the plug to rotate outward to an inclined position. At this time, the distance between the two arc-shaped grooves increases and the opening tilts upward, making it easier to clean the attached dust with tools such as cotton swabs. At the same time, the gap between the plug and the infrared transmitter and receiver also widens, making it convenient to adjust the position of the optical components with slender tools such as tweezers, thus ensuring that the infrared light can pass through the light-transmitting hole normally. After cleaning, the plug is turned back to the vertical position and the stop block is moved to relock the rack, which restores the fixture to normal use, thereby simplifying the maintenance process and avoiding the problem of dust clogging the light-transmitting hole and affecting the accuracy of the test.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a product testing fixture with plugs, including a housing 1. The housing 1 has a vertically penetrating assembly groove 11. Two plugs 3 are symmetrically mounted on the top of the assembly groove 11 via a pivot 32. (Refer to...) Figure 4 The lower end of plug 3 is connected to a wire, and the other end of the wire passes through the mounting slot 11 and is electrically connected to the external sound and light alarm. Both plugs 3 have arc-shaped slots 31 on the side that are close to each other. An infrared transmitter 4, an infrared receiver 5 and an indicator light 6 are fixedly installed on the upper side wall of the housing 1. The infrared transmitter 4 and the infrared receiver 5 are respectively fixed to both sides of plug 3 by bolts. The installation angle of the infrared transmitter 4 and the infrared receiver 5 can be finely adjusted. The indicator light 6 is electrically connected to the infrared receiver 5.

[0034] The assembly slot 11 is equipped with a locking mechanism 7. When both plugs 3 are perpendicular to the upper surface of the housing 1, the locking mechanism 7 fixes the position of the plugs 3. At this time, the two arc-shaped slots 31 are joined together to form a light-transmitting hole. The light-transmitting hole is located below the plug 3 and socket 2 insertion area. The light emitted by the infrared transmitter 4 passes through the light-transmitting hole and is received by the infrared receiver 5.

[0035] During testing, the socket 2 on the product is plugged into the two plugs 3. If the socket 2 is plugged in properly, it will block the light-transmitting hole, preventing the infrared receiver 5 from receiving the light emitted by the infrared transmitter 4. This will trigger the indicator light 6 to illuminate, indicating to the operator that the socket 2 and plugs 3 are properly connected and subsequent testing can proceed. Then, the socket 2 is connected to an external power source via a wire. If the product is fault-free, the audible and visual alarm will be powered through the socket 2 and will emit an audible and visual alarm, indicating that the product is normal. If the audible and visual alarm does not respond, the product is considered to be faulty.

[0036] If indicator light 6 does not light up after plugging in, the operator needs to check whether socket 2 and plug 3 are plugged in properly. After eliminating the plugging problem, the test can continue to avoid false detection.

[0037] It should be noted that the sound and light alarm, infrared transmitter 4, infrared receiver 5, and indicator light 6 are all commercially available and mature products, and their working principles will not be elaborated here.

[0038] The structure of locking mechanism 7 is described in detail below, with reference to... Figure 5 , Figure 6 , Figure 7 and Figure 10 The locking mechanism 7 includes two half gears 71 that are respectively fixedly installed on the two plugs 3. The axis of the half gears 71 is collinear with the axis of the rotating shaft 32. A rack 72 is horizontally slidably arranged inside the assembly groove 11 at the position corresponding to each half gear 71. The rack 72 meshes with the corresponding half gear 71. A guide groove 73 is provided on the rack 72. A T-shaped positioning block 74 is slidably installed inside the guide groove 73. The T-shaped positioning block 74 is fixedly installed on the inner wall of the assembly groove 11. The cooperation between the T-shaped positioning block 74 and the guide groove 73 can restrict the rack 72 to move horizontally only along the direction of the guide groove 73, thereby ensuring the stable meshing of the rack 72 and the half gear 71.

[0039] The locking mechanism 7 also includes a stop 75 disposed between the two racks 72. One end of the stop 75 slides through the housing 1 and extends outward. A protrusion 76 is fixedly installed on the upper side wall of the stop 75 at a position outside the housing 1. A limiting plate 77 is fixedly installed on one side of the housing 1 via a bracket. The limiting plate 77 is located on the side of the stop 75 away from the housing 1. When the stop 75 is moved closer to the housing 1, the protrusion 76 contacts the housing 1, preventing the stop 75 from moving closer. When the stop 75 is moved away from the housing 1, the limiting plate 77 contacts the stop 75, preventing it from moving further away. This design restricts the movement path of the stop 75, ensuring that its end can be inserted between the two racks 72, while preventing the stop 75 from detaching from the housing 1.

[0040] When the plug 3 is perpendicular to the upper surface of the housing 1, the end of the rack 72 away from the center of the housing 1 contacts the inner wall of the mounting groove 11, and the ends of the two racks 72 that are close to each other contact the two sides of the stop block 75 respectively. At this time, the inner wall of the mounting groove 11 and the stop block 75 together restrict the horizontal movement of the rack 72. Then, through the meshing of the rack 72 and the half gear 71, the plug 3 is restricted from rotating around the shaft 32, thereby fixing the plug 3 in a vertical position so as to test the socket 2.

[0041] It is worth noting that the inner diameter of the light-transmitting hole is limited by the size of the plug 3 and cannot be set too large. When dust particles accumulate on the inner wall of the arc groove 31 due to long-term use, there is a risk that the dust will block the light-transmitting hole. Once the light-transmitting hole is blocked, the light emitted by the infrared transmitter 4 cannot be received by the infrared receiver 5, which will cause the indicator light 6 to stay on for a long time and fail to perform normal detection. At this time, the dust on the inner wall of the arc groove 31 needs to be cleaned. However, due to the small inner diameter of the light-transmitting hole and the limited gap between the plug 3 and the infrared transmitter 4 and infrared receiver 5, the cleaning work is inconvenient and there is a risk of damaging the infrared transmitter 4 and infrared receiver 5.

[0042] To facilitate cleaning dust particles from the inner wall of the arc-shaped groove 31, refer to Figure 8 and Figure 9 The operator can first pull the stop 75 away from the housing 1 to disengage it from the two racks 72, thus releasing the restriction of the stop 75 on the racks 72. Then, push the two plugs 3 in sequence to rotate them outward around the shaft 32 to an inclined state. During this process, the plugs 3 drive the half gear 71 to rotate, and the half gear 71 drives the rack 72 to move horizontally towards the center of the housing 1 until the inner wall of the guide groove 73 away from the center of the housing 1 contacts the T-shaped positioning block 74. At this time, the T-shaped positioning block 74 blocks the rack 72 from moving further, thereby restricting the rotation of the half gear 71 and preventing it from disengaging from the rack 72. It also restricts the tilt angle of the plugs 3. At this time, the distance between the two arc-shaped grooves 31 increases, and the opening tilts upward, making it easier for the operator to use cotton swabs or other tools to clean the dust particles attached to the inner wall of the arc-shaped grooves 31. In addition, the gap between the plug 3 and the infrared transmitter 4 and infrared receiver 5 is also increased accordingly, which makes it easier to use slender tools such as tweezers to adjust the position of the infrared transmitter 4 and infrared receiver 5, ensuring that the infrared light can pass through the light-transmitting hole normally and ensuring the normal use of the testing fixture.

[0043] After cleaning, the operator first turns the plug 3 back to the position perpendicular to the upper side wall of the housing 1, and then inserts the end of the stop 75 into the position where it contacts the two racks 72, so that the normal use of the fixture can be restored.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
