Description

Technical Field

[0001] This utility model relates to the field of electrical test wire connector technology, specifically a connector for electrical testing. Background Technology

[0002] Electrical testing is conducted before an electrical system or equipment is put into use to determine whether there are any quality problems in its installation or manufacturing, and to verify whether newly installed or operating electrical equipment can be put into normal operation. This involves testing and verifying the insulation performance, electrical characteristics, and mechanical properties of each individual electrical device in the electrical system according to the relevant provisions of standards, regulations, and specifications. Through these tests and verifications, defects, errors, and quality problems in the manufacturing and installation of electrical equipment can be identified and eliminated in a timely manner, ensuring that the electrical system and equipment can be put into normal operation.

[0003] Currently, most existing quick-connect plugs use manual knobs or snap-lock mechanisms. In actual operation, testers need to carefully align the plug and socket interfaces and lock them by manually rotating the knob or pressing the snap. This process is not only time-consuming and laborious, but also requires a high level of skill from the operator. If the operation is not done properly, the plug and socket may not be able to connect tightly, resulting in poor contact. Poor contact can not only cause unstable signal transmission, but may also cause short circuits due to localized overheating, or even damage the test equipment, posing a safety hazard to the testers.

[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] Please see Figure 1-3This application proposes an electrical testing connector, which includes a plug 1 and a connector 2. A first sleeve 3 is fitted on the outer surface of the plug 1, and the inner wall of the first sleeve 3 is threaded to the outer surface of the plug 1. The outer surface of the connector 2 is provided with a threaded structure on the side corresponding to the plug 1, which can be threaded to the first sleeve 3. A second sleeve 4 is provided on the side of the first sleeve 3 facing away from the connector 2. The end of the second sleeve 4 facing away from the first sleeve 3 extends to the end of the plug 1, and the end is provided with an annular block 5 that can abut against the end of the plug 1. This design not only improves the stability of the connection, but also ensures a tight connection between the plug 1 and the connector 2 through the abutment action of the annular block 5.

[0019] Furthermore, the second sleeve 4 is provided with an annular limiting block 6 at one end facing the first sleeve 3, and the first sleeve 3 is provided with an annular limiting groove 7 at the corresponding position of the annular limiting block 6, which allows it to be limited and rotated. The cooperation between the annular limiting block 6 and the annular limiting groove 7 ensures the stability of the second sleeve 4 during movement, prevents it from shifting during movement, and makes the contact unstable, thereby further improving the reliability of the connection.

[0020] Furthermore, an annular positioning groove 8 is provided on the outer periphery of the side of the connector 2 corresponding to the plug 1, and an annular positioning block 9 is provided on the plug 1 corresponding to the annular positioning groove 8. This design enables the plug 1 to be quickly positioned when inserted into the connector 2, improving the efficiency and accuracy of the connection. The cooperation between the annular positioning groove 8 and the annular positioning block 9 can not only quickly align the interface between the plug 1 and the connector 2, but also prevent the plug 1 from shaking during the insertion process to a certain extent, ensuring the stability of the connection.

[0021] Furthermore, the annular positioning block 9 is symmetrically provided with positioning rods 10 on one side facing the annular positioning groove 8. The annular positioning groove 8 is provided with positioning holes 11 for the positioning rods 10 to be inserted. The cooperation between the positioning rods 10 and the positioning holes 11 further improves the connection stability between the plug 1 and the connector 2, ensuring that the plug 1 and the connector 2 can be tightly connected. This design can not only prevent the plug 1 from loosening during the connection process, but also improve the vibration resistance of the connection to a certain extent, and is suitable for various complex test environments.

[0022] Furthermore, a first magnet 12 is provided at one end of the positioning rod 10 facing the positioning hole 11, and a second magnet 13 is provided at the bottom of the positioning hole 11 that can attract the first magnet 12. This design further enhances the connection stability between the plug 1 and the connector 2 through the attraction of the magnet, preventing the plug 1 and the connector 2 from becoming loose due to vibration or external force. The attraction of the magnet can not only ensure the tightness of the plug 1 and the connector 2 during the connection process, but also improve the anti-interference ability of the connection to a certain extent, ensuring the stability of the test process.

[0023] When using this electrical testing connector, first insert the plug 1 into the connector 2. Initial positioning is achieved through the cooperation of the annular positioning block 9 and the annular positioning groove 8. The positioning rod 10 is then inserted into the positioning hole 11 to further ensure a tight connection between the plug 1 and the connector 2. Next, rotate the first sleeve 3 to make it threadedly connect with the outer surface of the connector 2. Simultaneously, the first sleeve 3 moves, driving the second sleeve 4 to move until the annular limiting block 6 abuts against the end of the plug 1 facing away from the connector 2, tightly abutting the connector 2 and preventing poor contact. This design not only allows for quick connection between the plug 1 and the connector 2 but also ensures the stability and reliability of the connection, improving the efficiency and safety of electrical testing.

[0024] In summary, the electrical testing connector of this utility model achieves a quick and stable connection between the plug 1 and the connector 2 through a reasonable structural design; the design of the positioning rod 10 and the magnet further improves the reliability of the connection and avoids the problem of poor contact; the connector is easy to operate, has strong applicability, and has high practical value and promotion prospects.
