Fastener 12 at the free end; First connecting component 20 includes an intermediate connector 21 connected to the L-shaped plug body 11 and an intermediate protective component 22 sleeved outside the intermediate connector 21; Second connecting component 30 includes a connector 31 inserted into the intermediate connector 21 and a plug-in housing 32 sleeved outside the connector 31; The intermediate protective component 22 is inserted into the plug-in housing 32, the connecting plate 40 is installed on the plug-in housing 32, and the cap 60 is used to cover the connector 31 after it is separated from the intermediate connector 21. The intermediate connector 21 is used to connect external cables.

[0022] The working principle of the elbow connector of this utility model is as follows: The L-shaped plug body 11 allows the cable to be inserted at a bending angle. The fastener 12 will firmly lock the inserted external cable onto the L-shaped plug body 11 to prevent the cable from loosening and causing poor contact. The wires inside the cable will be directly connected to the intermediate connector 21 of the first connecting component 20. The power connector 31 of the second connecting component 30 will be inserted into the intermediate connector 21 to form a conductive path. At this time, current or signal can be transmitted from the external cable through the intermediate connector 21 and the power connector 31 to the external device (such as a socket or instrument interface) connected to the power connector 31. The connecting plate 40 and the flexible connecting strip 50 are used to connect the cap 60. When it is necessary to separate the intermediate connector 21 and the power connector 31, the cap 60 can easily cover the power connector 31 to protect the internal structure.

[0023] Compared to existing technologies, the elbow connector of this utility model uses a connecting plate 40 and a flexible connecting strip 50 to connect a cap 60. When it is necessary to separate the intermediate connecting piece 21 and the electrical connector 31, the cap 60 can easily cover the electrical connector 31, protecting the internal structure from environmental factors such as dust and moisture, and extending the service life of the connector. The L-shaped plug body 11 design allows the cable to be inserted at a bending angle, while the fastener 12 ensures that the external cable is firmly locked on the plug body, avoiding poor contact caused by cable loosening.

[0024] Please refer to Figure 2 and Figure 3 The first connecting assembly 20 also includes an external thread 23 disposed on the intermediate protective member 22, and the wiring assembly 10 also includes an internal thread 13 disposed on the L-shaped plug body 11. The intermediate protective member 22 and the L-shaped plug body 11 are threadedly connected by the external thread 23 and the internal thread 13. The threaded connection method can provide a strong mechanical connection force, ensuring a more secure connection between the intermediate protective member 22 and the L-shaped plug body 11, reducing loosening caused by vibration or external force; the threaded connection method allows the intermediate protective member 22 and the L-shaped plug body 11 to be easily disassembled and installed, facilitating maintenance and replacement of internal components, and reducing maintenance costs and time.
