Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical debugging technology, and specifically relates to a test line anti-misinsertion structure for a debugging box and a debugging box with an anti-misinsertion structure. Background Technology
[0002] During the commissioning of electrical equipment, the commissioning box serves as a crucial testing tool, and the correct connection of its test leads directly affects the accuracy of the test results and the safety of the equipment. Currently, conventional commissioning boxes are typically equipped with positive and negative test leads. To facilitate differentiation, positive test leads are generally marked in red, while negative test leads are marked in black. Workers primarily rely on the color difference to determine the correct connection and installation of the test leads.
[0003] However, in practical applications, factors such as complex working environments, operator fatigue, and distraction make color-coding alone ineffective, leading to frequent mis-insertion of test leads. Incorrect insertion of positive and negative test leads not only results in incorrect debugging data but can also cause short circuits, damage equipment, and even threaten operator safety. While some existing technologies offer improvements to test lead connections, most are complex and costly, failing to meet the practical needs for efficient, convenient, and safe debugging. Therefore, a simple, low-cost, and highly reliable test lead mis-insertion prevention structure for debugging boxes is urgently needed to address these technical problems. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a test lead anti-misinsertion structure for a debugging box and a debugging box with an anti-misinsertion structure. By setting positive anti-misinsertion slots and negative anti-misinsertion slots with different orientations in the positive and negative terminals respectively, and setting anti-misinsertion blocks on the positive and negative terminals respectively, a physical restriction is formed from the structure, fundamentally eliminating the possibility of test lead misinsertion.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A test lead anti-misinsertion structure for a test box and a test box with the anti-misinsertion structure are disclosed. The test box includes a positive terminal and a negative terminal. The positive terminal mates with the positive terminal sleeve of the positive test lead, and the negative terminal mates with the negative terminal sleeve of the negative test lead. A positive positioning post is provided inside the positive terminal, and a negative positioning post is provided inside the negative terminal. A positive anti-misinsertion slot is provided on the positive positioning post, and a negative anti-misinsertion slot is provided on the negative positioning post. The positive anti-misinsertion slot mates with a positive anti-misinsertion plug on the positive terminal sleeve, and the negative anti-misinsertion slot mates with a negative anti-misinsertion plug on the negative terminal sleeve. The positive and negative anti-misinsertion slots are in different orientations.
[0007] Preferably, the inner wall of the positive electrode socket is provided with a positive electrode positioning guide groove, which is adapted to the positive electrode positioning plate on the positive electrode socket.
[0008] Preferably, the inner wall of the negative electrode socket is provided with a negative electrode positioning guide groove, which is adapted to the negative electrode positioning plate on the negative electrode socket.
[0009] Preferably, the opening of the positive electrode positioning guide groove gradually decreases from top to bottom, and the positive electrode positioning guide groove and the negative electrode positioning guide groove have the same shape and direction.
[0010] Preferably, the positive electrode anti-misinsertion plug is disposed on the inner wall of the positive electrode socket, and the negative electrode anti-misinsertion plug is disposed on the inner wall of the negative electrode socket.
[0011] Preferably, the positive terminal anti-misinsertion slot and the negative terminal anti-misinsertion slot are 90 degrees apart in orientation.
[0012] Preferably, the positive and negative anti-misinsertion slots are provided with guide chamfers at their openings.
[0013] Preferably, the outer walls of both the positive and negative electrode sockets are covered with an insulating and wear-resistant layer.
[0014] Preferably, the positive electrode socket, negative electrode socket, positive electrode positioning post, and negative electrode positioning post are conductive materials. When the positive electrode socket comes into contact with the positive electrode positioning post, a circuit is formed, and when the negative electrode socket comes into contact with the negative electrode positioning post, a circuit is formed.
[0015] A debugging box with an anti-misinsertion structure is provided, which uses the aforementioned anti-misinsertion structure for test leads to prevent test leads from being inserted into the wrong position.
[0016] The present invention can achieve the following beneficial effects:
[0017] 1. By setting up positive and negative anti-misinsertion slots with different orientations in the positive and negative terminals respectively, and by setting corresponding anti-misinsertion blocks on the positive and negative terminals, a physical restriction is formed structurally, fundamentally eliminating the possibility of test lead misinsertion. Even if the staff is negligent, the positive and negative terminals cannot be mismatched, effectively avoiding serious consequences such as incorrect debugging data and equipment short circuit damage caused by misinsertion, greatly ensuring the accuracy of debugging work and equipment safety.
[0018] 2. The design incorporates a positioning guide groove and positioning insert plate structure, reducing operational difficulty. Previously, operators were required to precisely control the insertion direction of the test leads. This new structure only requires ensuring the general direction is correct; the fitting relationship between the positioning guide groove and the positioning insert plate facilitates easy installation, significantly improving operational efficiency. It is particularly suitable for long-duration, high-intensity debugging work scenarios, reducing the workload of operators. Attached Figure Description

Detailed Implementation
[0025] Preferred solutions include Figures 1 to 4 As shown, a test lead anti-misinsertion structure for a debugging box includes a positive terminal 1 and a negative terminal 2. The positive terminal 1 mates with the positive terminal sleeve 3 of the positive test lead, and the negative terminal 2 mates with the negative terminal sleeve 4 of the negative test lead. A positive positioning post 5 is provided inside the positive terminal 1, and a negative positioning post 6 is provided inside the negative terminal 2. A positive anti-misinsertion slot 7 is provided on the positive positioning post 5, and a negative anti-misinsertion slot 8 is provided on the negative positioning post 6. The positive anti-misinsertion slot 7 mates with a positive anti-misinsertion plug 9 on the positive terminal sleeve 3, and the negative anti-misinsertion slot 8 mates with a negative anti-misinsertion plug 10 on the negative terminal sleeve 4. The positive anti-misinsertion slot 7 and the negative anti-misinsertion slot 8 are in different orientations. The positive anti-misinsertion plug 9 is located on the inner wall of the positive terminal sleeve 3, and the negative anti-misinsertion plug 10 is located on the inner wall of the negative terminal sleeve 4. In this embodiment, the positive anti-misinsertion slot 7 and the negative anti-misinsertion slot 8 are 90 degrees apart in orientation. If other test leads also need to be designed to prevent misinsertion, the orientation of the anti-misinsertion slots can be set differently based on the principle of this invention.
[0026] Conventional testing boxes typically come equipped with positive and negative test leads. The positive test lead is usually red, and the negative test lead is usually black. Normally, workers install the test leads according to their colors, but mis-insertion can still occur. This invention, based on existing technology, mainly adds a positive anti-mis-insertion slot 7, a negative anti-mis-insertion slot 8, a positive anti-mis-insertion plug block 9, and a negative anti-mis-insertion plug block 10. Because the positive anti-mis-insertion slot 7 and the negative anti-mis-insertion slot 8 are positioned differently, when the positive plug 3 is mistakenly inserted into the negative socket 2, the positive plug 3 cannot be fully inserted into the negative socket 2 because the positive anti-mis-insertion plug block 9 cannot match the positive anti-mis-insertion slot 7. Similarly, this also prevents the negative plug 4 from being mistakenly inserted into the positive socket 1.
[0027] Since the positive terminal anti-misinsertion slot 7 and the negative terminal anti-misinsertion slot 8 prevent misinsertion by setting different directions, and it is necessary to ensure that the insertion direction of the positive terminal plug 3 and the negative terminal plug 4 is fixed, a positive terminal positioning guide groove 11, a positive terminal positioning plate 12, a negative terminal positioning guide groove 13, and a negative terminal positioning plate 14 are designed to facilitate operation. This reduces the difficulty of operation for workers. It is not necessary to ensure that the insertion direction of the positive terminal plug 3 and the negative terminal plug 4 is completely fixed; it is only necessary to ensure that the approximate orientation of the positive terminal plug 3 and the negative terminal plug 4 is correct before insertion for easy installation. The specific solution is as follows:
[0028] The inner wall of the positive terminal socket 1 is provided with a positive terminal positioning guide groove 11, which is adapted to the positive terminal positioning plate 12 on the positive terminal socket 3. The inner wall of the negative terminal socket 2 is provided with a negative terminal positioning guide groove 13, which is adapted to the negative terminal positioning plate 14 on the negative terminal socket 4. The opening of the positive terminal positioning guide groove 11 gradually decreases from top to bottom, and the positive terminal positioning guide groove 11 and the negative terminal positioning guide groove 13 have the same shape and direction. Correspondingly, the width of the positive terminal positioning plate 12 and the negative terminal positioning plate 14 gradually increases from bottom to top.
[0029] The positive terminal anti-misinsertion slot 7 and the negative terminal anti-misinsertion slot 8 are provided with guide chamfers at their openings. The angle of the guide chamfers is 45°-60°, which is used to guide the anti-misinsertion blocks to be smoothly inserted into the corresponding slots.
[0030] The outer walls of both the positive electrode socket 3 and the negative electrode socket 4 are covered with an insulating and wear-resistant layer. The insulating and wear-resistant layer is made of polytetrafluoroethylene and has a thickness of 1-3 mm.
[0031] Positive plug 3, negative plug 4, positive positioning post 5 and negative positioning post 6 are conductive. Positive plug 3 and positive positioning post 5 form a circuit when they come into contact, and negative plug 4 and negative positioning post 6 form a circuit when they come into contact.
[0032] A debugging box with an anti-misinsertion structure is provided, which uses the aforementioned anti-misinsertion structure for test leads to prevent test leads from being inserted into the wrong position.
[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
