[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This application provides a pinhole wire for cable testing, which solves the problem that existing test leads cannot meet the testing requirements of plug contacts and socket holes of different diameters, and achieves stability when testing plug contacts and socket holes of different diameters.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1 As shown, a pin-hole wire for cable testing includes a banana plug 1 and a pin structure 2. The pin structure 2 is provided with multiple pins, and the multiple pins located on the same pin structure 2 are all male pins or female pins.

[0041] The pin structure 2 is connected to the banana plug 1 via a wire to form a test path;

[0042] The banana plug 1 is plugged into the matching multimeter and, together with the wire and pin structure 2, serves as the red or black probe for continuity and insulation testing.

[0043] Multiple pins of different models are located on the same pin structure 2. According to the size of each pin model, multiple pins of different models are arranged and soldered on the wire.

[0044] By setting pinhole wires and multiple pins of different models on the pinhole wires, two pinhole wires are set in actual use and connected to the matching multimeter through the corresponding banana plug 1. They are used as red or black test probes for continuity and insulation testing. This solves the problem that existing test probes cannot meet the testing of plug contacts and socket holes of different diameters, and achieves stability when testing plug contacts and socket holes of different diameters.

[0045] During setup, multiple pins of different models are arranged and soldered on the wire according to the size of each pin model. By arranging and soldering multiple pins of different models, it is convenient to use the corresponding pin model.

[0046] It should be noted that when using two pin wires as the red or black test probes, all pins on one pin wire are male, and all pins on the other pin wire are female. The two pin wires are used to perform continuity and insulation tests on the cable plug and cable socket respectively.

[0047] Specifically, depending on actual needs, each needle hole line is equipped with 4-6 male or female needles of different models.

[0048] Among them, the banana plug can be in lantern flower style or other styles, and the pins should preferably be male and female copper pins of aviation connectors. The specific type and size should be selected according to the usage requirements.

[0049] The design and production process of a pinhole wire: Based on actual usage requirements, first determine the number of test branches, connector type and specifications of a pinhole wire. According to the connector specifications, select a wire of appropriate length and performance. Solder the wire to banana plug 1 and male and female pins, and use heat shrink tubing to protect and fix the soldered parts. This completes the production of a new type of test pinhole wire.

[0050] like Figure 1 As shown, each of the pins has anti-slip textured sections distributed on its outer surface, and the number of anti-slip textured sections is set according to the pin sequence number.

[0051] By incorporating anti-slip grooves, testers can easily grip the cable plug or socket for insertion testing, improving stability during the testing process. Additionally, distributing different numbers of anti-slip grooves to different models facilitates the differentiation of multiple pin types.

[0052] like Figures 2-4 As shown, a winding structure 4 is installed on the pin structure 2. The winding structure 4 includes an elastic ring 40, a soft magnetic strip 401, and a scale tape 402. The scale tape 402 matches and adheres to the soft magnetic strip 401 in the unfolded state.

[0053] The elastic ring 40 is fixedly connected to the stretching end of the soft magnetic strip 401, and the winding structure 4 is sleeved on the pin through the elastic ring 40.

[0054] In the initial state, the soft magnetic strip 401 is wound up in a planar coil shape.

[0055] By setting up a winding structure 4, which is in the form of an elastic ring 40 and a soft magnetic strip 401, the winding of the soft magnetic strip 401 itself drives the winding and stretching of the scale tape 402, thereby making it easier for testers to observe the scale on the scale tape 402. This prevents the test cable plug contacts and socket holes from being too numerous, which could lead to test confusion and omissions.

[0056] like Figures 2-4 As shown, the flexible magnetic strip 401 is fitted onto the corresponding cable plug contact or cable socket hole through the auxiliary structure 3;

[0057] Part of the auxiliary structure 3 is embedded in the cavity of the flexible magnetic strip 401 and is fixedly connected to the end of the flexible magnetic strip 401.

[0058] By setting up auxiliary structure 3, the winding structure 4 is limited, which improves the stability during the test. When in use, one end of the winding structure 4 is fixed to the cable plug or cable socket through auxiliary structure 3, which facilitates the movement of the pin for point-by-point testing. The scale 402 on the soft magnetic strip 401 moves with the movement of the pin, thereby indicating the location of the corresponding test point and preventing the problem of test confusion caused by too many test points.

[0059] Specifically, the auxiliary structure 3 has an annular groove 302, and the soft magnetic strip 401 is partially rolled in the annular groove 302. The annular groove 302 is used to initially limit the rolling range of the soft magnetic strip 401, thereby improving the stability of the rolling of the soft magnetic strip 401.

[0060] like Figures 2-4 As shown, one of the pins is provided with a connecting part 22, and an annular groove 221 is provided on the connecting part 22. The elastic ring 40 is fitted into the annular groove 221 for binding. The annular groove 221 is used to limit the elastic ring 40 and prevent the elastic ring 40 from coming off the pin during use.

[0061] In one embodiment, such as Figures 2-4 As shown, when multiple pins on the same pinhole line are all female pins, they are used for continuity and insulation testing of plug contacts.

[0062] Each of the pins has a test hole 201 on its plug portion 20. Each test hole 201 has a chamfer and is fitted onto the corresponding cable plug contact one by one to perform tests on multiple contacts.

[0063] The auxiliary structure 3 has a insertion hole 301 with the same diameter as the test hole 201 of the corresponding female needle, which is used to be sleeved onto the corresponding cable plug contact and rotated to connect with the contact.

[0064] By setting a plug hole 301 on the auxiliary structure 3 with the same diameter as the corresponding test hole 201, the plug hole 301 is inserted into the corresponding contact point to assist the winding operation of the soft magnetic strip 401 on the winding structure 4.

[0065] Specifically, when the elastic ring 40 is fitted onto the annular groove 221, the inner diameter of the elastic ring 40 is larger than the outer diameter of the pin plug 20. When the auxiliary structure 3 and the winding structure 4 are in use, the soft magnetic strip 401 on the winding structure 4 does not contact the pin to be tested when the pin is inserted one by one into the test point in the same horizontal or vertical direction, which can better realize the detection of the pin into the test point.

[0066] It should be noted that by setting the convolution thickness of the flexible magnetic strip 401, the flexible magnetic strip 401 will not interfere with the detection process during use.

[0067] like Figure 2 As shown, the auxiliary structure 3 is provided with a plug rod 31 on the side away from the plug hole 301;

[0068] The outer diameter of the plug rod 31 matches the diameter of the test hole 201;

[0069] The auxiliary structure 3 is connected to the corresponding female pin through the plug rod 31 and the test hole 201.

[0070] By setting the plug rod 31, the plug rod 31 and the test hole 201 can be used to fix the corresponding pin of the auxiliary structure 3 when the pin wire is not in use, which facilitates the storage of the auxiliary structure 3 and effectively prevents the problem of the auxiliary structure 3 being inconvenient to store when the pin wire is not in use.

[0071] Similarly, in another embodiment, compared to the above-described embodiment of the female needle and the auxiliary structure 3 used for the female needle, the male needle and the auxiliary structure 3 used for the male needle are specifically as follows:

[0072] Multiple pins located on the same pinhole line are all male pins, used for continuity and insulation testing of cable socket holes;

[0073] Compared to the female needle, the male needle does not have a test hole 201, and the auxiliary structure 3 used by the male needle does not have a plug hole 301. During testing, the male needle is inserted into the cable socket hole for testing, and the auxiliary end 30 on the auxiliary structure 3 is also inserted into the corresponding cable socket hole for limiting. The male needle has an insertion hole on the tail 21 for plugging and limiting the auxiliary end 30 on the auxiliary structure 3, so as to realize the storage of the auxiliary structure 3 used by the male needle.

[0074] The working principles of the male and female needles are existing technologies and will not be elaborated upon.

[0075] When testing cable plugs or sockets with fewer contacts or sockets during operation, a pin-hole wire with multiple pins can be used. The pins of different models on the pin-hole wire can be used to test contacts or sockets of different diameters. Depending on the specific model of the contact or socket, the corresponding model of pin (male or female) on the pin-hole wire can be selected, and the continuity and insulation test can be performed by connecting the wire and banana plug 1 with a multimeter. There is no need to install auxiliary structure 3 on the corresponding model of pin.

[0076] When testing cable plugs or sockets with a large number of contacts or sockets, it should be noted that most contacts on the same plug or sockets on the same socket are arranged neatly and of the same model, with only a few contacts or sockets differing in model. For example, a certain type of test cable mainly consists of three parts: a plug, a socket, and a cable bundle. The plug's model number is JF5-231TDA-2, and the socket's model number is JF5-231Z3A. This plug model has a total of 231 contacts, including 8 large contacts for 40A with a contact diameter of 1 mm; 8 medium contacts for 20A with a contact diameter of 2 mm; and 215 small contacts for 5A with a contact diameter of 3.5 mm.

[0077] For individual contacts or sockets, the corresponding pins on the pinhole line can be used for testing directly. For most contacts or sockets that are arranged in a regular manner and have the same model, they need to be used in conjunction with winding structure 4 or in conjunction with winding structure 4 and auxiliary structure 3.

[0078] When using auxiliary structure 3, the auxiliary structure 3 is fitted into the annular groove 221 via the elastic ring 40, thereby binding the auxiliary structure 3 with the corresponding model pin. Testing is performed sequentially either vertically or horizontally. Figure 4 As shown, the circles represent multiple interfaces on the plug or multiple sockets on the socket. When testing them one by one in a horizontal direction, the pins are first inserted into the corresponding contacts or sockets to test the first few. Then, the auxiliary structure 3 is embedded in the previously tested connectors or sockets to limit their movement, and the pins continue to move to test the subsequent interfaces or sockets in the same row. During the pin testing process, the elastic ring 40 on the pin drives the soft magnetic strip 401 to pull, which in turn pulls the scale strip 402 on the soft magnetic strip 401 (the above-mentioned related structures have been described in detail, and the working principle is similar to the internal structure of a measuring tape, so it will not be repeated here). By using the increased distance that the scale strip 402 stretches as the pins are pulled one by one, the pins are controlled to move in the same row. Based on the scale strip 402 showing the approximate length of the last stretch, the pins can be effectively prevented from being retested or missed, thus improving the accuracy of the test.

[0079] Finally, after the test is completed, remove the auxiliary structure 3 and the corresponding pins from the plug interface or socket hole, and use the self-winding of the soft magnetic strip 401 on the winding structure 4 to reset the winding structure 4, so that the auxiliary structure 3 can be reused.

[0080] When in use, the different models of pins and sockets have good compatibility with the corresponding plug contacts and sockets of the cable under test, ensuring smooth insertion and reliable contact. This guarantees the safety of the plug and socket of the cable under test and solves the problems that occur when using multimeter probes (pins) for testing, such as unstable contact between the plug contacts and probe pins, mismatch between probe pins and sockets, resulting in unstable contact, inability to insert probes, or damage to the sockets when probes are forcibly inserted.

[0081] It should be noted that when using auxiliary structure 3 for auxiliary testing, batch testing is performed on the same batch of cable plugs or cable sockets. Therefore, it is not necessary to frequently replace auxiliary structure 3. During batch testing, only one auxiliary structure 3 that matches the corresponding majority of plug interfaces or socket holes is required.

[0082] In summary, compared with existing technologies, it has the following beneficial effects:

[0083] 1. By setting pinhole wires and multiple pins of different models on the pinhole wires, two pinhole wires are set in actual use and connected to the matching multimeter through the corresponding banana plug 1. They are used as red or black test probes for continuity and insulation testing. This solves the problem that the existing test probes cannot meet the testing of plug contacts and socket holes of different diameters, and achieves stability when testing plug contacts and socket holes of different diameters.

[0084] During setup, multiple pins of different models are arranged and soldered on the wire according to the size of each pin model. By arranging and soldering multiple pins of different models, it is convenient to use the corresponding pin model.

[0085] 2. By setting anti-slip grooves, it is easier for testers to pinch the cable plug or cable socket for insertion testing, which improves the stability during the testing process. At the same time, by distributing different numbers of anti-slip grooves for different models, it is easy to distinguish between multiple pin models.

[0086] 3. By setting up a winding structure 4, which is in the form of an elastic ring 40 and a soft magnetic strip 401, the winding of the soft magnetic strip 401 itself drives the winding and stretching of the scale tape 402, thereby making it easier for testers to observe the scale on the scale tape 402. This prevents the test cable plug contacts and socket holes from being too numerous, which could lead to test confusion and omissions.

[0087] It should be noted that, in this document, relational terms such as "first" and "second" are used only 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.
