[0023] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0024] This embodiment provides a relay terminal, which is arranged between the male terminal and the female terminal to connect the circuit between the two, and can be connected to the probe of the detection device for detecting the circuit, such as Figures 1 to 3 As shown, it includes a male end connection part 1 and a female end connection part 2 connected to the male end connection part 1, the male end connection part 1 is provided with a plug hole 101 along the axial direction of the relay terminal, the male terminal is inserted into the plug hole 101, and the female end connection part 2 is plugged with the female terminal. The female end connection part 2 includes at least two connection sections 201 that are sequentially connected and coaxially arranged along the axial direction of the relay terminal, and the radial dimensions of the at least two connection sections 201 are progressively arranged from away from the male end connection part 1 to close to the male end connection part 1.

[0025] In this embodiment, the male terminal is inserted into the socket 101 along the axial direction of the socket 101, thereby realizing the electrical connection between the relay terminal and the male terminal; the female terminal is plugged into the female end connection part 2 to ensure the integrity and stability of the circuit loop. In this embodiment, three connecting sections 201 are provided on the female end connection part 2, which are connected in sequence and coaxially arranged. The progressive design of the three connecting sections 201 enables the female end connection part 2 to provide better stability and adaptability when plugging in the female terminal, thereby ensuring the reliability of the connection. It should be understood that in other embodiments, the combination of multiple specifications of the connecting section 201 can also be used to realize the use of the whole vehicle plug, reduce the number of relay plugs, and reduce costs.

[0026] In actual use, the relay terminal is set between the male terminal and the female terminal to be detected, and plugged and connected to the two respectively. At this time, the probe of the detection device is overlapped on the relay terminal to detect the state of the circuit at this time.

[0027] Through the above technical solution, by plugging and connecting the male connecting part 1 with the male terminal and the female connecting part 2 with the female terminal, the circuit continues to be connected when the male and female terminals are disconnected, and can be connected to the probe of the detection device to facilitate the detection of the state of the circuit, thereby solving the problem of being unable to measure and obtain the characteristic values ​​under the required working conditions when testing the wiring harness.

[0028] In some embodiments, reference Figure 2 and Figure 3, a plurality of contact springs 102 are arranged along the circumference of the socket 101, and the middle part of each contact spring 102 is recessed toward the axial direction of the socket 101, thereby forming an arc-shaped contact surface for abutting against the outer surface of the male terminal. In this embodiment, a plurality of contact springs 102 are arranged at equal intervals, and the elastic force is applied stably, thereby improving the stability of the electrical connection between the contact spring 102 and the male terminal. When the male terminal is inserted into the socket 101, the arc-shaped contact surface abuts against the outer wall of the male terminal, and the contact spring 102 applies elastic force to the male terminal from multiple directions to clamp it, so that the male terminal and the male terminal connecting part 1 that are plugged into each other have a greater plug-in and pull-out force, so that the male terminal is not easy to fall out of the socket 101.

[0029] In some embodiments, reference Figure 1 and Figure 2 A recessed hole 103 is provided on the outer peripheral surface of the male end connecting portion 1 for the probe to be inserted and electrically connected. The design of the recessed hole 103 enables the probe of the detection device to be inserted and fixed, avoiding accidental separation of the probe and the relay terminal during the detection process, and ensuring the accuracy of the measured value.

[0030] In some embodiments, reference Figure 1 and Figure 2 The number of the concave holes 103 is multiple, and the multiple concave holes 103 are arranged at intervals along the circumference of the male end connecting portion 1. This design increases the flexibility and reliability of the connection between the probe and the relay terminal, and further improves the accuracy of the detection.

[0031] In some embodiments, reference Figure 1 and Figure 2 , an annular groove 104 is provided on the outer peripheral surface of the male end connection part 1 along its circumference for the probe to clamp and electrically connect. The probe of the detection device can be clamped in this annular groove 104, so as to achieve electrical connection with the male end connection part 1. The design of the annular groove 104 can provide a larger contact area, further improving the stability of the connection and the accuracy of the detection. Therefore, in other embodiments, the probe can also be replaced with a pen clip, which is clamped in this annular groove 104 by the pen clip to achieve electrical connection with the male end connection part 1, freeing the hands of the staff and improving work efficiency.

[0032] In some embodiments, Figure 1 As shown, at least part of the outer circumference of the male end connection part 1 is provided with anti-slip grooves 105. The anti-slip grooves 105 are arranged along the circumference of the male end connection part 1, which helps the relay terminal to provide better grip and stability during installation and operation, and further improves work efficiency.

[0033] In order to improve the overall strength and durability of the relay terminal, in some embodiments, the male end connection part 1 and the female end connection part 2 are integrally formed, and at least two connection sections 201 are integrally formed. This design not only simplifies the production process, but also ensures the stability and reliability of the relay terminal during use.

[0034] In some embodiments, the material of the relay terminal is a conductive metal material. In this embodiment, the relay terminal can be made of materials such as copper and aluminum, which have good conductivity and mechanical strength and can meet the use requirements of the relay terminal in the circuit connection and detection process.

[0035] In order to improve the conductivity and corrosion resistance of the surfaces of the contact spring 102 and the female end connection part 2, in some embodiments, the surfaces of the contact spring 102 and the female end connection part 2 are both provided with a coating. The coating material can be selected from metals with good conductivity and corrosion resistance such as tin and silver.

[0036] Although the preferred embodiments of the present disclosure have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.

[0037] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is also intended to include these modifications and variations.
