Abstract
Description
Technical Field
[0001] This utility model relates to the field of test machine interface technology, and in particular to a test machine interface error prevention mechanism. Background Technology
[0002] The test machine connection board is a circuit board (PCB) that integrates multiple interface types. Through circuit design, it connects the core modules of the test machine (such as signal source and data acquisition unit) with the device under test, external modules or sensors to realize the transmission of electrical signals, data and power. It is like a "bridge" of the test system. It must be compatible with the interface standards of the device under test (such as USB, JTAG, CAN bus) and ensure the stability of the test signals. It is the core hub of physical connection and signal interaction in the test process.
[0003] Currently, the test machine connection board usually has a large number of standardized sorting interfaces, and each interface can be connected to each other. In order to distinguish sorting interfaces with different functions, the traditional method mainly relies on the color of the connecting wires. However, this method has obvious defects. Under high-intensity work, operators are very likely to misconnect the sorting interfaces due to visual fatigue or negligence. Once misconnection occurs, it will directly affect the normal operation of the sorting machine, resulting in serious quality deviations in the sorting results, and thus causing a series of problems such as reduced production efficiency and increased product rework rate. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a test machine interface error prevention mechanism, which aims to improve the problem that the existing test machine connection board mainly relies on the color marking of the connection wire, which can easily lead to incorrect connection of the sorting interface.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a test machine interface anti-foolproof mechanism, comprising a substrate, wherein the substrate is provided with fixing holes for mounting and fixing the substrate; the substrate is provided with a plurality of first mounting holes and second mounting holes, the width between the first mounting holes being greater than the width between the second mounting holes, and the first mounting holes and second mounting holes being separated by a partition groove; further comprising a first connector and a second connector, the first connector being adapted to be installed in the second mounting hole, the second connector being adapted to be installed in the first mounting hole, and the width of the second connector being greater than the width of the first connector; the surface of the substrate is provided with a plurality of label slots, the label slots being correspondingly provided on one side of each first connector and second connector; a slot is provided on the side of the first mounting hole and the second mounting hole near the mounting surface of the substrate, which can hold a rubber gasket.
[0006] Furthermore, the number of fixing holes is at least two, symmetrically distributed on the substrate, for stable mounting of the substrate.
[0007] Furthermore, the label slot is rectangular in shape, its size is adapted to the label pasting, and the edges of the label slot are chamfered to facilitate label pasting and replacement.
[0008] Furthermore, the rubber gasket is made of wear-resistant rubber, which can effectively buffer the friction between the connector and the substrate.
[0009] This utility model has the following beneficial effects:
[0010] 1. In this utility model, by utilizing the difference in width between the first mounting hole and the second mounting hole, the difference in size between the first connector and the second connector, and the label slot for pasting markings, the misconnection of the external control mechanism and the sorting interface of the sorting machine is avoided from multiple dimensions, ensuring the accuracy of equipment connection and operation, and reducing the risk of equipment failure and sorting abnormalities caused by misconnection.
[0011] 2. In this utility model, different mounting holes are separated by partition grooves. Combined with size differences and label markings, it is easy for installers to quickly distinguish and operate accurately, improving installation and debugging efficiency. It is also beneficial for quick identification of connector functions and corresponding interfaces during later maintenance and repair, saving manpower and time costs. Attached Figure Description

[0017] 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.
[0018] Reference Figure 1-3This utility model provides an embodiment of a test machine interface anti-foolproof mechanism, including a substrate 1, a fixing hole 7 on the substrate 1 for mounting and fixing the substrate 1; a plurality of first mounting holes 9 and second mounting holes 10 are provided on the substrate 1, the width between the first mounting holes 9 is greater than the width between the second mounting holes 10, and the first mounting holes 9 and second mounting holes 10 are separated by a partition groove 5; it also includes a first connector 2 and a second connector 3, the first connector 2 is adapted to be installed in the second mounting hole 10, the second connector 3 is adapted to be installed in the first mounting hole 9, and the width of the second connector 3 is greater than the width of the first connector 2; a plurality of label grooves 4 are provided on the surface of the substrate 1, the label grooves 4 are correspondingly provided on one side of each first connector 2 and second connector 3; a slot 8 is provided on the side of the first mounting hole 9 and the second mounting hole 10 near the mounting surface of the substrate 1, which can hold a rubber gasket 6;
[0019] Specifically, the device uses a substrate 1 as its core support. The substrate 1 is securely mounted using fixing holes 7, providing a reliable foundation for the entire device. Several first mounting holes 9 and second mounting holes 10 are strategically arranged on the substrate 1. The design of the first mounting holes 9 being wider than the second mounting holes 10, combined with the separation groove 5, creates a clear and intuitive distinguishing structure, allowing users to quickly identify the different mounting holes. The device is equipped with first connectors 2 and second connectors 3, which can be inserted into the second mounting holes 10 and the first mounting holes 9 respectively. Because the second connector 3 is wider than the first connector 2, the size difference makes them easy to distinguish during use. This physical structure prevents misconnection between the external control mechanism and the sorting machine's sorting interface, ensuring... For accurate connection, the label slots 4 on the surface of the substrate 1 for each connector support the pasting of exclusive labels, further enhancing differentiation through identification. This double protection reduces the risk of misconnection, ensuring accurate identification even in complex usage scenarios or when multiple people are operating and maintaining the system, thus improving operational reliability. In addition, the first mounting hole 9 and the second mounting hole 10 are provided with a structure that allows rubber gaskets 6 to be inserted on the side of the substrate 1 near the mounting surface. When the first connector 2 and the second connector 3 are installed on the substrate 1, the rubber gaskets 6 can effectively buffer the contact between the two and the surface of the substrate 1, reducing friction and collision during installation and use, delaying component wear, extending the service life of the connectors and the substrate 1, reducing the probability of failure and maintenance costs caused by wear, and ensuring long-term stable operation of the device.
[0020] Working Principle: The device is supported by a base plate 1, which is fixed in place by fixing holes 7. Several first mounting holes 9 and second mounting holes 10 are provided on the base plate 1. The width between the first mounting holes 9 is greater than the width between the second mounting holes 10, and a partition groove 5 separates the first mounting holes 9 and second mounting holes 10 for easy identification by the user. The device includes a first connector 2 and a second connector 3, which can be installed correspondingly inside the second mounting holes 10 and the first mounting holes 9. The second connector 3 will be wider than the first connector 2, allowing the device to be used with the correct orientation based on the first connector 2 and the second connector 3. The size of the device 3 is differentiated to prevent misconnection between the external control mechanism and the sorting interface of the sorting machine. At the same time, multiple label slots 4 are provided on the surface of the substrate 1. The label slots 4 are respectively set on one side of each first connector 2 and second connector 3, so that the corresponding label can be pasted inside the label slot 4, further preventing misconnection between the external control mechanism and the sorting interface of the sorting machine. The second mounting hole 10 is provided on the side of the first mounting hole 9 and the second mounting hole 10 near the mounting surface of the substrate 1, so that the rubber gasket 6 can be inserted, thereby preventing the first connector 2 and the second connector 3 from being worn on the surface of the substrate 1 when they are installed on the substrate 1.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
