[0032] When in use, first connect the male terminal 23 on the male connector 200 to the connection terminal on the electrical product to lead the connection end of the electrical product out of the narrow space, and connect the signal input terminal cable with the female terminal 33 on the female socket 300. After completion, match and plug the female socket 300 on the male connector 200, and finally rotate the second end cap 34 at the tail end of the female socket 300 to push the second rubber core 32 to drive the female terminal 33 to move toward the male connector 200, so that the second rubber core 32 abuts against the first rubber core 22, and at the same time push the second locking piece on the second shell 31 to snap into the first locking piece 24 on the male connector 200, so that the female socket 300 is fixed on the male connector 200 and the conductive connection of the line is completed, which is convenient to operate and has a stable connection.
[0033] The utility model provides a male connector 200 equipped with a male terminal 23 and a female base 300 equipped with a female terminal 33, so that the connection end of the electrical product can be led out of a narrow space and then the circuit is turned on, which is convenient for connection operation; by respectively providing a matching first locking member 24 and a second locking member on the first shell 21 and the second shell 31, and providing a second end cap 34 at the rear end of the female base 300 that can drive the second locking member to rotate, the female base 300 and the male connector 200 can be conveniently and quickly locked and assembled together, and disassembly and assembly are convenient.
[0034] Further, such as Figure 3As shown, the outer wall of the second shell 31 is a stepped structure that is larger in the middle and smaller at both ends, and a stop ring 36 is clamped on the outer wall of the end facing the male head 200, and a second locking member is provided on the inner wall of the end of the stop ring 36 facing the male head 200; a retaining spring 37 extending along its circumference and having a V-shaped structure is embedded on the outer wall of the second shell 31, and both arms of the retaining spring 37 are continuously bent toward the second shell 31 and their ends are both against the outer wall of the second shell 31, and the middle part of the retaining spring 37 extends toward the outside of the second shell 31.
[0035] In this embodiment, if Figure 4 As shown, the inner wall of the retaining ring 36 is provided with a plurality of second slots 1 which are continuously arranged in the circumferential direction and extend in the axial direction. The middle part of the retaining spring 37 can be matched and inserted into each second slot 1 to fix the retaining ring 36 on the outer wall of the second housing 31 .
[0036] It can be understood that when the structural layout of the electrical product changes, there is no need to change the first shell 21 and the second shell 31. It is only necessary to change the end size of the stop ring 36 and the size of the second locking member thereon (that is, to replace the specifications of the stop ring 36) to quickly complete the quick clamping and fixing of the first shell 21 and the second shell 31. The retaining spring 37 can press against the second shell 31 during the process of the second shell 31 being driven to rotate by the second end cap 34 to prevent the two from loosening or sliding relative to each other, thereby ensuring that the locked first shell 21 and the second shell 31 continue to remain in a locked state, ensuring that the circuit continues to remain in a conductive state.
[0037] In this embodiment, if Figure 5 As shown, the first locking member 24 includes one or more first slots 2 provided on the outer wall of the first housing 21, each of the first slots 2 is provided with one or more inclined or spirally ascending first protrusions 3, and the plurality of first slots 2 and first protrusions 3 are uniformly provided on the outer wall of the first housing 21 along the circumferential direction and are integrally formed therewith; Figure 3 As shown, each second locking member includes a plurality of second protrusions 4 evenly arranged along the circumferential direction, each second protrusion 4 can be rotated and pushed into a first clamping groove 2 and one side wall thereof can be matched and clamped with a first protrusion 3; a guide thread 5 is further provided on the outer wall of the first housing at one axial side of the plurality of first clamping grooves 2 close to the female seat 300, and a plurality of axially extending grooves 6 are provided on the guide thread 5. Figure 6 As shown, the inner wall of the stop ring 36 is provided with two or more guide protrusions 7 evenly arranged along the circumferential direction, each second protrusion 4 and guide protrusion 7 can pass through a cut groove 6 during the plug-in process of the male head 200 and the female seat 300, and each guide protrusion 7 can match with the guide thread 5 and slide along it when the second shell 31 rotates.
[0038] In this embodiment, the first housing 21, the second housing 31 and the stop ring 36 are all provided with matching foolproof structures for quick and correct connection. When in use, first align the foolproof structures one by one, and push the female seat 300 to correctly sleeve on the periphery of the male head 200, the second protrusion 4 and the wire protrusion 7 are respectively passed through the slot 6 to reach the periphery of the first housing 21, and then the second end cap 34 is rotated to drive the stop ring 36 to rotate through the second housing 31, so that the second protrusion 4 can be screwed into the first slot 2 and pressed against the first protrusion 3, and at the same time drive the guide protrusion 7 to slide on the guide thread 5 and further prevent the first housing 21 and the second housing 31 from loosening.
[0039] Further, such as Figure 2-3 As shown, the first end cap 25 and the second end cap 34 are both annular structures, and a shielding member 100 is matched and mounted on the inner wall thereof.
[0040] In this embodiment, if Figure 7 As shown, each shielding member 100 includes a sleeved insulating ring 11 and a shielding ring 12: the outer wall of the insulating ring 11 is a stepped structure, and its end with a larger diameter is embedded in the first end cap 25 or the second end cap 34, and its shoulder is transmission-connected to the first shell 21 or the second shell 31, and its end with a smaller diameter extends into the first shell 21 or the second shell 31; the shielding ring 12 is embedded in the inner wall of the end with a larger diameter of the insulating ring 11; a sealing ring 13 and a slip ring 14 are also provided on the periphery of the smaller end of each insulating ring 11, the sealing ring 13 is embedded in the outer wall of the insulating ring 11, the slip ring 14 is sleeved on the end of the insulating ring 11 and transmission-connected thereto through the buckle 8, and the slip ring 14 is arranged on the inner side of the first shell 21 or the second shell 31 and slidingly connected thereto.
[0041] It can be understood that the shielding member 100 can shield the electromagnetic interference of external signals on the connection between the male connector 200 and the female connector 300 and the electrical products and / or cables, thereby ensuring continuous, stable and reliable transmission of electrical signals.
[0042] In this embodiment, if Figure 4 , 5 As shown in FIGS. 7 and 7 , the shoulder of each insulating ring 11 and the ends of the first shell 21 and the second shell 31 are provided with matching serrations 9; the end of each insulating ring 11 with a larger diameter is provided with a plurality of cantilever beams 10 uniformly arrayed along the circumferential direction, and the end of each cantilever beam 10 extends toward the inner side of the insulating ring 11 and abuts against the shielding ring 12.
[0043] It can be understood that the serrations 9 can ensure that the shielding member 100 keeps synchronous movement with the first shell 21 and the second shell 31 to avoid relative sliding to cause wear and affect the electromagnetic shielding effect.
[0044] In this embodiment, in order to ensure that the male terminal 23 remains stable during the plugging process, a first limit snap ring 26 is further provided on the first shell 21 to clamp the first rubber core 22 on its inner wall; in order to ensure that the retaining ring 36 and the second shell 31 remain relatively stable, a retaining ring positioning groove 371 is provided on the outer wall of the second shell 31 to clamp the retaining ring 37, and a retaining ring installation groove 381 is provided on its axial side to clamp the second limit snap ring 38, so as to ensure that the retaining ring 37 is stable and can limit the relative axial displacement of the retaining ring 36 and the second shell 31 after the retaining ring 37 is suddenly subjected to force and accidentally slides out of the second clamping groove 1.
[0045] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
