DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 5 As shown, an interlocking mating male and female terminal proposed in one embodiment of the present application includes:

[0026] The male end body 1 includes a connecting wire 101, and a pin 102 is connected to the free end of the connecting wire 101;

[0027] The female end body 2 includes a connecting plate 201, one end of which is provided with a connecting column 202, and one end of the connecting column 202 away from the connecting plate 201 is provided with a cylindrical plug hole 203 for inserting the plug pin 102;

[0028] The locking mechanism 3 includes a docking portion 301 installed on the outer peripheral side of the pin 102, and a limiting portion 302 acting on the docking portion 301 is installed on the connecting column 202. When the pin 102 is inserted into the cylindrical socket 203 and rotated to a certain angle, the docking portion 301 is clamped in the limiting portion 302. That is to say, when in use, the pin 102 is first inserted into the cylindrical socket 203, and then the pin 102 is rotated. After the pin 102 is rotated, the docking portion 301 can be clamped in the limiting portion 302, thereby completing the interlocking, so that when encountering a vibration environment and being pulled by external force, the pin 102 can be effectively prevented from being separated from the cylindrical socket 203, thereby reducing the possibility of causing safety accidents.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the docking portion 301 includes a limit plate installed on the outer peripheral side of the pin 102, and the limit portion 302 includes an arc plate 3021 constructed at the free end of the connecting column 202, and a limit arc groove 3022 is opened at one end of the arc plate 3021 for inserting the limit plate, and a limit component 5 acting on the limit plate is installed on the connecting column 202. When the limit plate is located in the limit arc groove 3022, the limit plate is fixed in the limit arc groove 3022 by the limit component 5. That is to say, when the pin 102 is inserted into the cylindrical socket 203, the pin 102 is rotated at this time so that the limit plate is located in the limit arc groove 3022. At this time, the limit component 5 will fix the limit plate in the limit arc groove 3022 to prevent the pin 102 from accidentally rotating and causing the limit plate to detach from the limit arc groove 3022.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, a slide groove 503 is provided at the free end of the connecting column 202, and the limiting assembly 5 includes a positioning plate 501 slidably inserted in the slide groove 503, one end of the positioning plate 501 is located outside and is flush with one end of the arc plate 3021 having a limiting arc groove 3022, and a return spring 502 is installed between the other end of the positioning plate 501 and the slide groove 503. When the limiting plate is located in the limiting arc groove 3022, one side of the positioning plate 501 is in contact with one side of the limiting plate. When the limiting plate is located in the limiting arc groove 3022, the return spring 502 is in a normal state. Some contact between one side of the positioning plate 501 and the limiting plate prevents the pin 102 from rotating in the cylindrical socket 203, thereby effectively preventing the limiting plate from detaching from the limiting arc groove 3022.

[0031] Such as 1. Figure 3 and Figure 5As shown, in some embodiments, an arc groove 6 is provided at one end of the limiting arc groove 3022, and an arc push plate 7 is slidably installed in the arc groove 6. One end of the arc push plate 7 is flush with one end of the arc plate 3021 having the limiting arc groove 3022, and a driving spring 4 is installed between the other end of the arc push plate 7 and the arc groove 6. When the limiting plate is not in the limiting arc groove 3022, the arc push plate 7 abuts against one side of the positioning plate 501. When the limiting plate is in the limiting arc groove 3022, the arc push plate 7 is completely located in the arc groove 6, and the driving spring 4 is in a compressed state. When the pin 102 needs to be pulled out of the cylindrical socket 203, it only needs to be moved The positioning plate 501 causes the positioning plate 501 to move into the slide groove 503. At this time, the driving spring 4 will reset due to its own elastic deformation, thereby causing the arc plate push plate 7 to move into the limiting arc groove 3022. During the movement of the arc plate push plate 7, the limiting plate will be pushed to move, thereby causing the pin 102 to rotate. Subsequently, after the positioning plate 501 is released, the positioning plate 501 will push the limiting plate to move due to the reset of the return spring 502, thereby causing the limiting plate to move away from the cylindrical socket 203. Therefore, the pin 102 can be automatically pulled out by only turning the positioning plate 501, which is more convenient when the pin 102 needs to be pulled out from the cylindrical socket 203.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the number of the arc plates 3021 is two and they are distributed in a circular array, and the connecting column 202 is equipped with an adjusting member 8 for driving the two positioning plates 501 to move simultaneously, that is to say, the number of the positioning plates 501 and the limit plates is also two, which can effectively improve the firmness of the interlocking, and the two positioning plates 501 can be moved simultaneously through the adjusting member 8, thereby improving the firmness of the interlocking and facilitating the removal of the pin 102 from the cylindrical socket 203.

[0033] like Figure 5As shown, in some embodiments, the adjusting member 8 includes a driving ring 801 slidably mounted on the connecting column 202, one end of the driving ring 801 is configured with a connecting sleeve 802, a gap is left between the connecting sleeve 802 and the connecting column 202, a through groove 803 connected to the slide groove 503 is opened on the outer side of the connecting column 202, one side of the positioning plate 501 is configured with a convex plate 804 passing through the through groove 803, one end of the connecting sleeve 802 is configured with an executive plate 805, one side of the executive plate 805 is connected to the convex plate 804 contacts the side away from the connecting plate 201, and a locking piece 9 is installed on the connecting column 202 for releasing the limit or limiting the movement of the connecting sleeve 802. That is to say, when the connecting sleeve 802 is moved, the movement of the connecting sleeve 802 will drive the execution plate 805 to move, so that the execution plate 805 contacts the protruding plate 804. Because the protruding plate 804 is connected to the positioning plate 501, the two positioning plates 501 will move at the same time at this time, which is convenient and quick to use, and the locking piece 9 can effectively prevent the connecting sleeve 802 from moving accidentally.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments, the locking member 9 includes a plate body 901 constructed on the outer peripheral side of the connecting column 202, and a first mounting plate 902 is constructed on one side of the plate body 901, and a movable groove 903 is opened on one side of the first mounting plate 902 along its length direction. A sleeve rod 904 passing through the movable groove 903 is constructed on the outer side of the connecting sleeve 802, and a pressing sleeve 905 is slidably sleeved on one end of the sleeve rod 904, and a reset spring piece 906 is installed between the sleeve rod 904 and the pressing sleeve 905. A limiting member acting on the pressing sleeve 905 is installed on the plate body 901. When the sleeve 905 is pressed, the limit on the sliding freedom of the connecting sleeve 802 is released by the limiting member 10, and the pressing sleeve 9 05 In normal conditions, the sliding freedom of the connecting sleeve 802 is limited by the limiting member 10. That is to say, when the connecting sleeve 802 needs to be moved, it is only necessary to press the pressing sleeve 905, so that the sliding freedom of the connecting sleeve 802 can be released through the limiting member 10. After the connecting sleeve 802 is moved, the pressing sleeve 905 can be released to limit the connecting sleeve 802. In this embodiment, the plate body 901, the first mounting plate 902 and the limiting member 10 are two in number. In this way, when the connecting sleeve 802 needs to be moved, two pressing sleeves 905 need to be pressed to move the connecting sleeve 802. When one of the pressing sleeves 905 is accidentally pressed, the other limiting member 10 can continue to limit the connecting sleeve 802.

[0035] like Figure 4As shown, in some embodiments, the limiting member 10 includes a second mounting plate 1001 constructed at the free end of the plate body 901, and a slot 1002 for a pressing sleeve 905 to pass through is provided on the second mounting plate 1001. A plurality of limiting slots 1003 are provided along the length direction of the second mounting plate 1001 on one side close to the first mounting plate 902, and a positioning block 1004 for being inserted into the limiting slot 1003 is configured on the pressing sleeve 905. The positioning block 1004 is positioned Between the first mounting plate 902 and the second mounting plate 1001, that is, when the pressing sleeve 905 is pressed, the movement of the pressing sleeve 905 will cause the positioning block 1004 to move out of one of the limit grooves 1003, and then when the pressing sleeve 905 is moved, the connecting sleeve 802 can be moved. When the pressing sleeve 905 is released, the pressing sleeve 905 can be moved and reset through the reset spring piece 906, so that the positioning block 1004 is reinserted into one of the limit grooves 1003.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
