[0038] The utility model provides a waterproof electric connector lock panel opening nut type and snap spring type fixing structure, be applied to mounting plate 100, be equipped with mounting hole 110 on mounting plate 100.

[0039] Please refer to Figures 1 to 8 In an embodiment of the utility model, the waterproof electric connector lock panel opening nut type and snap spring type fixing structure comprises:

[0040] The plug assembly 200 comprises a first connecting part 210, a wire harness 220, a second connecting part (not shown), one end of the wire harness 220 is connected to the first connecting part 210, the other end of the wire harness 220 is connected to the second connecting part, further, the first connecting part 210 and one end of the wire harness 220 can form a first plug, the second connecting part and the other end of the wire harness 220 can form a second plug, wherein the second connecting part is provided as a rubber shell. The first connecting part 210 is provided with a first protrusion 211 and a mounting part 212, the mounting part 212 and the second connecting part can pass through the mounting hole 110 and are arranged on one side of the mounting plate 100, and the first protrusion 211 is arranged on the other side of the mounting plate 100, that is, when the plug assembly 200 is mounted, the rubber shell can pass through the mounting hole 110 on the mounting plate 100, wherein the mounting part 212 on the first connecting part 210 can pass through the mounting hole 110, while the first protrusion 211 cannot pass through the mounting hole 110, that is, part of the structure of the first connecting part 210 can pass through the mounting hole 110. Further, since one end of the wire harness 220 is connected to the first connecting part 210 and the other end is connected to the second connecting part, at this time the first connecting part 210 and the second connecting part can play a protective effect on both ends of the wire harness 220, so that the plug assembly 200 can avoid damage to both ends of the wire harness 220 during transportation. It should be noted that in the prior art, during transportation, the other end of the wire harness 220 is not connected to the second connecting part, that is, one end of the wire harness 220 is connected to the first connecting part 210, and the other end is not connected to the rubber shell, at this time the end not connected to the rubber shell is easy to be damaged during transportation, thereby affecting the use of the wire harness 220.

[0041] Further, it should be noted that, Figures 1 to 4 The first connecting part 210 in the above embodiment is of a type, Figures 5 to 8 The first connecting part 210 in the above embodiment is of another type.

[0042] The positioning part 300 is detachably connected with the mounting part 212. Since the mounting part 212 can pass through the mounting hole 110 and be located on one side of the mounting plate 100, when the positioning part 300 is connected with the mounting part 212, the positioning part 300 is also located on one side of the mounting plate 100. It can be understood that the positioning part 300 and the first protrusion 211 are respectively arranged on opposite sides of the mounting plate 100. At this time, the positioning part 300 can clamp the mounting plate 100 with the first protrusion 211, so that the first connecting part 210 is positioned on the mounting plate 100. Since the positioning part 300 is detachably connected with the mounting part 212, when the first connecting part 210 is assembled, the second connecting part does not need to be detached, that is, the rubber shell on the wire harness 220 does not need to be detached, thereby reducing the installation process, improving the convenience of installation, and solving the technical problems existing in the prior art. Since the wire harness 220 is always connected with the second connecting part during transportation and assembly, the second connecting part can also play a protective effect on the wire harness 220.

[0043] In an embodiment, with reference to Figure 2 、 Figure 4 , the mounting part 212 comprises a threaded segment 213 arranged outside the first connecting part 210.

[0044] The positioning part 300 is configured as an open ring structure 310, and the opening of the open ring structure 310 is used for the wire harness 220 to enter and exit. The positioning part 300 is connected with the threaded segment 213. It can be understood that the positioning part 300 is connected with the threaded segment 213, and at this time, the positioning part 300 also corresponds to a threaded hole. Since the positioning part 300 is configured as an open ring structure 310, and the opening of the open ring structure 310 is used for the wire harness 220 to enter and exit, when the second connecting part passes through the mounting hole 110, the positioning part 300 can enter the wire harness 220 into the open ring structure 310 through the opening when connected, and then the open ring structure 310 moves towards the first connecting part 210 and is connected with the threaded segment 213. As the open ring structure 310 moves close to the mounting plate 100, the distance between the open ring structure 310 and the first protrusion 211 becomes smaller, and the clamping force between the open ring structure 310 and the first protrusion 211 increases, thereby positioning the first connecting part 210 on the mounting plate 100.

[0045] In an embodiment, with reference to Figure 2 、 Figure 5 、 Figure 6In order to facilitate the operation of the positioning part 300, the outer side of the split ring structure 310 is provided with a plurality of first planes 311, and the plurality of first planes 311 are arranged along the circumferential direction of the positioning part 300. In this way, when rotating the positioning part 300 of the split ring structure 310, the first plane 311 can be used for operation. When operating, it can be hand-tightened or operated by a wrench or other tools. In some embodiments, in order to improve the strength of the positioning part 300, the positioning part 300 is configured to be a metal material.

[0046] In an embodiment, referring to Figure 2 、 Figure 6 In order to enable the split ring structure 310 to be stably arranged on the first connecting part 210, the caliber of the split ring structure 310 is smaller than the inner diameter of the split ring structure 310. It should be noted that the inner diameter of the split ring structure 310 is the inner diameter. By arranging the caliber of the split ring structure 310 to be smaller than the inner diameter of the split ring structure 310, on the one hand, the connection fastening property of the split ring structure 310 and the first connecting part 210 can be improved, and on the other hand, the carrying capacity of the split ring structure 310 can be improved. That is to say, when assembling the split ring structure 310, the split ring structure 310 can withstand a higher torque.

[0047] In an embodiment, referring to Figure 3 、 Figure 4 、 Figure 7 、 Figure 8The mounting portion 212 further comprises a clamping groove 214 arranged outside the first connecting portion 210. It can be understood that the first connecting portion 210 is provided with the threaded segment 213 and the clamping groove 214 outside. The positioning portion 300 is configured as a clamping spring 320 or the split ring structure 310. It should be noted that the user can select the corresponding positioning portion 300 according to the use requirement. If the split ring structure 310 is needed, the split ring structure 310 can be connected with the threaded segment 213 on the first connecting portion 210. If the clamping spring 320 is needed, the clamping spring 320 can be inserted into the clamping groove 214. When the clamping spring 320 is inserted into the clamping groove 214, the clamping spring 320 and the first protrusion 211 can clamp the mounting plate 100, so as to position the first connecting portion 210 on the mounting plate 100. Further, in some embodiments, in order to improve the clamping force of the clamping spring 320 and the first protrusion 211, a gasket can be arranged between the first protrusion 211 and the mounting plate 100. By arranging the clamping groove 214 and the threaded segment 213 outside the first connecting portion 210, the first connecting portion 210 can be adapted to the split ring structure 310 or the clamping spring 320, so as to improve the adaptability of the first connecting portion 210 and improve the application ability. It should be emphasized that the clamping spring 320 is configured as an open clamping spring 320. It should be noted that the above two mounting modes can solve the problem that the existing waterproof electrical connector is not convenient to mount on the panel. In this embodiment, the first connecting portion 210 is provided with the clamping groove 214 and the threaded segment 213, that is, the first connecting portion 210 can be adapted to the clamping spring 320 and the split ring structure 310, so as to integrate the two mounting modes into one, thereby realizing the purpose of multi-in-one.

[0048] When the positioning portion 300 is selected as the clamping spring 320, the cost can be significantly reduced compared with the split ring structure 310, and the working hours of unscrewing the split ring structure 310 can be removed during assembly, thereby improving the efficiency. If the requirement of the use environment of the equipment is high, the split ring structure 310 can be selected.

[0049] The design is not limited thereto, and in some embodiments, the mounting portion 212 can only comprise the clamping groove 214, that is, the first connecting portion 210 can only be provided with the clamping groove 214, and the positioning portion 300 is configured as the clamping spring 320.

[0050] In an embodiment, referring to Figure 2 、 Figure 4 、 Figure 6 、 Figure 8The first protrusions 211 are configured in a ring structure. When the first protrusions 211 are arranged in the ring structure, the contact area between the first protrusions 211 and the mounting plate 100 is increased. By increasing the contact area between the first protrusions 211 and the mounting plate 100, the force between the first protrusions 211 and the mounting plate 100 is increased, so that the first connecting portion 210 is stably limited on the mounting plate 100. In some embodiments, the first protrusions 211 can be arranged in a block structure. In this case, the number of the first protrusions 211 is multiple, and the multiple first protrusions 211 are arranged on the outer side of the first connecting portion 210.

[0051] In an embodiment, the mounting plate 100 is provided with second protrusions (not shown). When the positioning portion 300 and the first protrusions 211 clamp the mounting plate 100, the positioning portion 300 abuts against the second protrusions. The second protrusions are configured to allow a predetermined gap between the positioning portion 300 and the mounting plate 100. It should be noted that the predetermined gap facilitates the assembly of the positioning portion 300 and the first connecting portion 210. Specifically, because there is a predetermined gap between the positioning portion 300 and the mounting plate 100, a relatively large operation space is obtained when the positioning portion 300 is operated, which facilitates the operation of the user.

[0052] In an embodiment, the second protrusions are configured in a ring structure. Under the action of the ring structure, the surface of the second protrusions in contact with the positioning portion 300 is an entire plane, so that the force between the positioning portion 300 and the second protrusions is uniformly distributed. However, the design is not limited thereto. In some embodiments, the second protrusions can also be arranged in a block structure. In this case, the number of the second protrusions is multiple, and the multiple second protrusions are arranged along a circumference.

[0053] In an embodiment, with reference to Figure 2 , Figure 6, in order to reduce the self-rotation of the first connecting part 210 in the mounting hole 110, a second plane 120 is arranged in the mounting hole 110, and a third plane 230 is arranged outside the first connecting part 210 in correspondence with the second plane 120, the first connecting part 210 is inserted into the mounting hole 110, and the second plane 120 and the third plane 230 cooperate to limit the rotation of the first connecting part 210 in the circumferential direction, that is, the cooperation of the second plane 120 and the third plane 230 can reduce the self-rotation of the first connecting part 210 in the mounting hole 110, so when the positioning part 300 is configured as an open ring structure 310, the open ring structure 310 needs to be rotated and assembled outside the first connecting part 210 during assembly, and since the self-rotation amplitude of the first connecting part 210 is relatively small, the open ring structure 310 can be assembled more conveniently. It should be noted that when the first connecting part 210 is provided with a threaded segment 213, the third plane 230 can be arranged outside the threaded segment 213, and it can be understood that the third plane 230 is composed of a plurality of discontinuous planes. In an embodiment, the second plane 120 and the third plane 230 are both configured as two. However, the design is not limited thereto, and in some embodiments, the second plane 120 and the third plane 230 are both configured as three or four.

[0054] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application is included in the patent protection scope of the present application.
