Description

Technical Field

[0001] This utility model relates to the field of automation equipment, and in particular to a mechanism for detecting the breakage of a locking spring in an automotive connector. Background Technology

[0002] The car connector has a locking spring at the end, which is made of plastic and has a hole in the middle. The locking spring is snapped into the end of the car connector. During the production process, the locking spring needs to be fixed in the top hole. Since the locking spring is pushed into the car connector from the side hole, there is still a possibility that the locking spring may break after installation. Therefore, it is necessary to test the locking spring after installation to determine whether the locking spring is broken. Utility Model Content

[0003] Therefore, it is necessary to provide a mechanism for detecting the breakage of the locking spring of an automotive connector, addressing the problems in the existing technology.

[0004] A spring breakage detection mechanism for an automotive connector, characterized in that it includes a vertical cylinder mounted on the upper side of a fixed fixture via a bracket; the piston rod of the vertical cylinder is connected to a vertically movable connecting plate; a horizontally mounted first cylinder is mounted on the connecting plate; the piston rod of the first cylinder is connected to a movable plate; the movable plate has a first pawl; a second cylinder is mounted on the lower side of the movable plate; the piston rod of the second cylinder is connected to a second pawl; the first pawl and the second pawl approach and insert into the top hole of the automotive connector at the fixed fixture; and the first pawl and the second pawl move in different directions under the action of the first cylinder and the second cylinder.

[0005] In one embodiment, when the first and second jaws are brought together, the width of the first and second jaws is smaller than the inner diameter of the top hole of the car connector.

[0006] In one embodiment, both the first and second claws include a groove, which is located at the middle of the first and second claws. The lower side of the groove is provided with an abutment portion higher than the groove. When the first or second claw is inserted into the top hole of the car connector, the abutment portion abuts against the locking spring, and the groove abuts against the inner wall of the top hole.

[0007] In one embodiment, a third cylinder is provided on the lower side of the movable plate, the piston rod of the third cylinder is connected to a third chuck, and the movable plate is also provided with a fourth chuck corresponding to the third chuck.

[0008] In one embodiment, the movable plate is L-shaped and includes a horizontal part and a vertical part. The horizontal part is connected to the lower side of the connecting plate through a top guide rail slider structure. The side of the horizontal part is provided with a connecting rod connected to the piston rod of the first cylinder. The movable plate slides horizontally along the direction of the top guide rail slider on the lower side of the connecting plate.

[0009] In one embodiment, the bracket is provided with a horizontal guide rail on its side, and the second and third claws are provided with horizontal sliders on their sides. The horizontal sliders are slidably connected to the horizontal guide rail, and the second and third claws move horizontally along the direction of the horizontal guide rail.

[0010] In the aforementioned car connector spring breakage detection mechanism, after the first and second pawls extend into the top hole of the car connector, under the action of the first and second cylinders, the first and second pawls move outward, thereby abutting against the spring and pressing it outward. In this way, the spring is stretched from the inside. The force point of the first and second pawls is directly opposite the opening on the side of the car connector. If the spring breaks, it will be squeezed out from the opening on the side of the car connector, thus directly detecting whether the spring is broken. Attached Figure Description

Detailed Implementation

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] like Figures 1 to 3 As shown, a spring breakage detection mechanism for an automotive connector is characterized by comprising a vertical cylinder 3 mounted on the upper side of a fixed fixture 2 via a bracket 1. The piston rod of the vertical cylinder 3 is connected to a vertically movable connecting plate 4. A horizontally mounted first cylinder 5 is mounted on the connecting plate 4. The piston rod of the first cylinder 5 is connected to a movable plate 6. The movable plate 6 is provided with a first pawl 51. A second cylinder 7 is mounted on the lower side of the movable plate 6. The piston rod of the second cylinder 7 is connected to a second pawl 71. The first pawl 51 and the second pawl 71 approach and insert into the top hole of the automotive connector at the fixed fixture 2. The first pawl 51 and the second pawl 71 move in different directions under the action of the first cylinder 5 and the second cylinder 7.

[0019] After the first pawl 51 and the second pawl 71 are inserted into the top hole of the car connector, under the action of the first cylinder 5 and the second cylinder 7, the first pawl 51 and the second pawl 71 move outward, so that the first pawl 51 and the second pawl 71 abut against the locking spring and press the locking spring outward. In this way, the locking spring is stretched from the inside. The force point of the first pawl 51 and the second pawl 71 is directly opposite the opening position on the side of the car connector. If the locking spring breaks, the locking spring will be squeezed out from the opening position on the side of the car connector, thus directly detecting whether the locking spring is broken.

[0020] At this time, in order to insert the first jaw 51 and the second jaw 71 into the interior of the car connector, when the first jaw 51 and the second jaw 71 are brought together, their width is smaller than the inner diameter of the top hole of the car connector. Before testing, it is necessary to move both the first jaw 51 and the second jaw 71 into the interior of the car connector. Therefore, at this time, the first jaw 51 and the second jaw 71 are first brought together, and then moved downward under the action of the vertical cylinder 3, thereby moving into the interior of the car connector at the top hole position.

[0021] When the first claw 51 and the second claw 71 move outward, in order to push the locking spring outward, in this embodiment, both the first claw 51 and the second claw 71 include a groove 511. The groove 511 is located in the middle of the first claw 51 and the second claw 71. The lower side of the groove 511 is provided with an abutment portion 512 that is higher than the groove 511. When the first claw 51 or the second claw 71 is inserted into the top hole of the car connector, the abutment portion 512 abuts against the locking spring, and the groove 511 abuts against the inner wall of the top hole. At this time, in order to detect whether the locking spring is broken, the first pawl 51 and the second pawl 71 need to abut against the inner side of the locking spring and move outward from the inner side position to push the locking spring. However, during the movement of the first pawl 51 and the second pawl 71, they may collide with the inner wall of the car connector. In order to avoid this situation, the side walls of the first pawl 51 and the second pawl 71 are provided with grooves 511, which are directly opposite the inner wall of the top hole of the car connector. At the same time, a protruding abutment part 512 is provided on the lower side of the groove 511, which is directly opposite the inner wall of the locking spring. In this way, when the first pawl 51 and the second pawl 71 move outward, the abutment part 512 pushes the locking spring outward. Since the first pawl 51 and the second pawl 71 are provided with grooves 511, the abutment part 512 can move outward a certain distance, thereby exerting an outward pushing force on the locking spring.

[0022] To improve detection efficiency, two sets of detection structures are provided. To simplify the overall structure, in this embodiment, a third cylinder 8 is also provided on the lower side of the moving plate 6. The piston rod of the third cylinder 8 is connected to a third jaw 81, and the moving plate 6 also has a fourth jaw 52 corresponding to the third jaw 81. The second cylinder 7 and the third cylinder 8 are arranged side-by-side, with the third cylinder 8 having a corresponding third jaw 81. Simultaneously, a fourth jaw 52 is provided on the side of the moving plate 6, arranged side-by-side with the first jaw 51. Thus, the first cylinder 5 controls the moving plate 6, thereby simultaneously controlling the first jaw 51 and the fourth jaw 52. This creates two detection stations, allowing simultaneous detection of two products. Compared to having two first cylinders 5 and two second cylinders 7 arranged side-by-side, only the addition of a third cylinder 8 and its corresponding third jaw 81, and a fourth jaw 52 fixed to the moving plate 6, is needed to achieve simultaneous detection of two products.

[0023] The movable plate 6 is used by the first cylinder 5 to control the first jaw 51 and the fourth jaw 52. Therefore, in this embodiment, the movable plate 6 is L-shaped, including a horizontal part 61 and a vertical part 62. The horizontal part 61 is connected to the lower side of the connecting plate 4 through the top guide rail slider structure 63. The side of the horizontal part 61 is provided with a connecting rod connected to the piston rod of the first cylinder 5. The movable plate 6 slides horizontally along the direction of the top guide rail slider on the lower side of the connecting plate 4. Under the action of the top guide rail slider structure 63, the horizontal part 61 of the movable plate 6 slides linearly on the lower side of the connecting plate 4, thereby causing the movable plate 6 to move linearly as a whole, and thus the first jaw 51 and the fourth jaw 52 move linearly.

[0024] Meanwhile, to ensure that the second claw 71 and the third claw 81 maintain linear movement during the movement, in this embodiment, a horizontal guide rail 9 is provided on the side of the bracket 1, and a horizontal slider is provided on the side of the second claw 71 and the third claw 81. The horizontal slider is slidably connected to the horizontal guide rail 9, and the second claw 71 and the third claw 81 move horizontally along the direction of the horizontal guide rail 9. Thus, under the action of the horizontal guide rail 9 and the horizontal slider, the second claw 71 and the third claw 81 move linearly along the direction of the horizontal guide rail 9. In this way, the first claw 51, the second claw 71, the third claw 81, and the fourth claw 52 all move linearly. This ensures that the force acting on the locking spring is in a linear direction during the pressing of the locking spring, thereby ensuring the accuracy of the detection. Of course, since the cylinder connector is placed through the fixing fixture 2, the car connector is also in a fixed state at this time. This allows for effective detection of locking spring breakage while also ensuring the accuracy of the detection.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
