DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present application and combined with the accompanying drawings to further describe the technical solution of the present application, but the present application is not limited to these embodiments.

[0036] like Figure 1 As shown, the present application discloses an electrical connector, comprising: a first connector 1 and a second connector 2 that are plug-connected.

[0037] like Figure 2 As shown, the first connector 1 includes a base 11, three pins 13 are connected to the base 11, and the base 11 is also connected to a threaded tube 12. The threaded tube 12 is connected to the base 11 and extends to a side away from the base 11. The three pins 13 are all within the circumferential range of the threaded tube 12. The outer peripheral wall of the threaded tube 12 is provided with threads, and the cross-section of the inner cavity of the threaded tube 12 is an irregular circle.

The plug-in section 221 is plugged into the threaded tube 12 and one end of the pin 13 extends into the wiring hole 2211. One end of the locking section 222 close to the plug-in section 221 abuts against the end of the threaded tube 12 away from the base 11. The threaded sleeve 21 is sleeved on the end of the locking section 222 away from the plug-in section 221. The diameter of the plug-in section 221 is greater than the inner diameter of the threaded sleeve 21. The threaded sleeve 21 extends toward the side close to the plug-in section 221 to surround the plug-in section 221 in the threaded sleeve 21. The threaded sleeve 21 is threadedly connected to the outer peripheral wall of the threaded tube 12. The diameter of the wiring section 223 is smaller than the inner diameter of the threaded sleeve 21. The end of the wiring section 223 away from the locking section 222 is connected with a wire 2231.

[0039] like Figure 4 As shown, when the first connector 1 is connected to the second connector 2, the plug section 221 of the second connector 2 is inserted into the threaded tube 12 of the first connector 1. At this time, the pin 13 on the first connector 1 will extend into the wiring hole 2211 on the plug section 221 of the second connector 2, and an electrical connection is established between the pin 13 and the wiring hole 2211, so that current can flow from the first connector 1 to the second connector 2. When the plug-in is completed, the end of the locking section 222 close to the plug section 221 abuts against the end of the threaded tube 12 away from the base 11, and the threaded sleeve 21 is tightened on the outer peripheral wall of the threaded tube 12 by rotation. At this time, the other end of the locking section 222 abuts against the inner peripheral wall of the threaded sleeve 21, thereby locking the second connector 2 between the threaded tube 12 and the threaded sleeve 21, forming a firm mechanical connection, ensuring that the electrical connection between the pin 13 and the wiring hole 2211 is stable and reliable, and preventing loosening or falling off under external forces such as vibration or pulling. When disassembling, just rotate the locking sleeve in the opposite direction, and then remove it, and the second connecting member 2 can be easily pulled out from the first connecting member 1.

The plug-in block 1112 is plugged into the plug-in groove 1122 to form a relatively closed environment, which effectively protects the electrical components in the installation cavity 1111 and prevents them from being affected and damaged by the external environment.

[0043] A fixing block 1123 is provided on the cover plate 112 and extends axially toward one side of the installation cavity 1111. The through hole 1121 axially penetrates the fixing block 1123. One end of the fixing block 1123 abuts against the bottom of the installation cavity 1111. The fixing block 1123 is located at the through hole 1121 and a first avoidance groove 1124 is provided on the conductive sheet 14 corresponding to the conductive sheet 14.

[0046] Working principle: When connecting, the plug section 221 of the second connector 2 is inserted into the threaded tube 12 of the first connector 1, and the pin 13 on the first connector 1 will extend into the wiring hole 2211 on the plug section 221 of the second connector 2, and an electrical connection is established between the pin 13 and the wiring hole 2211, so that current can flow from the first connector 1 to the second connector 2. After the plug-in is completed, the end of the locking section 222 close to the plug section 221 abuts against the end of the threaded tube 12 away from the base 11, and the threaded sleeve 21 is tightened on the outer peripheral wall of the threaded tube 12 by rotation.
