Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Examples
Referring to fig. 1, the quick release type misplug prevention positioning structure of the connector described in this embodiment includes a positioning pin 100 disposed on a first plug 1 and a positioning hole 200 formed on a second plug 2, and only when the positioning pin 100 and the positioning hole 200 are completely matched, the first plug 1 and the second plug 2 can be plugged. The first and second socket bodies 1 and 2 may be either a connector plug or a socket.
Specifically, referring to fig. 2, in order to provide the positioning pin 100 on the first socket body 1, a mounting hole 110 is formed on the socket surface of the first socket body 1, the mounting hole (110) has a positioning portion 111 having a regular polygonal cross section and a connecting portion 112 having a circular cross section, the connecting portion 112 is a through hole, and a projected area of the positioning portion 111 completely covers the connecting portion 112 to form a stepped surface at the connection, and the positioning portion 111 is provided toward the socket surface for mounting the positioning pin 100 from the socket surface side.
Referring to fig. 3, corresponding to the structure of the mounting hole 110, the positioning pin 100 also includes a first pin body 101 having a cross section matched with the positioning portion 111 and a second pin body 102 having a cross section matched with the connecting portion 112, and an end of the second pin body 102 away from the first pin body 101 is provided with an annular groove 103, when mounting, the second pin body 102 is aligned with the connecting portion 112 and inserted from one side of the positioning portion 111, and the annular groove 103 protrudes out of an end surface of the connecting portion 112, and is embedded into the annular groove 103 by using the split washer 120 to perform a limiting and fixing function on the positioning pin 100, and when the most preferable second pin body 102 is completely inserted into the connecting portion 112, the annular groove 103 is just exposed, thereby ensuring a better fixing effect on the positioning pin 100. The installation structure of the positioning pin 100 is free from riveting or thread locking and the like, is simple and convenient to operate, and reduces the production cost and the later maintenance cost.
As a further optimized solution in this embodiment, the positioning pin 100 is configured to realize a multi-angle misplug prevention structure. As shown in fig. 3, the positioning pin 100 forms a positioning notch 104 with a directional positioning function on the first pin body 101 at an end far from the second pin body 102 through an axial tangent plane and a radial tangent plane, the positioning hole 200 of the second connector 2 has a filling portion corresponding to the shape and volume of the positioning notch 104, when the first plug-in body 1 is plugged with the second plug-in body 2, the positioning pin 100 can be completely inserted into the positioning hole 200 to realize complete connection only if the position of the filling part in the positioning hole 200 is matched with the positioning notch 104 on the positioning pin 100, otherwise the filling part forms an obstacle to the insertion of the positioning pin 100, thereby realizing the function of preventing the misplug, correspondingly, the size and the orientation of the positioning notch 104 are different, different plug-in unit misplug prevention can be realized, and the installation position of the first pin body 101 on the positioning pin 100 in the positioning part 111 can be completely determined according to the actual misplug prevention requirement because the positioning pin 100 is installed at the rear part.
As shown in fig. 3, as a further optimized solution in this embodiment, the center of the positioning pin 100 has a through threaded hole 105, a filling portion in the positioning hole 200 is also provided with a threaded portion matching with the threaded hole 105, the threaded portion can be spliced with the threaded hole 105 to form a complete thread, after the first plug-in body 1 and the second plug-in body 2 are plugged, the bolt 130 is screwed in from one end of the second pin body 102, and after the bolt 130 is screwed into the positioning hole 200 and finishes with the threaded portion of the filling portion, the first plug-in body 1 and the second plug-in body 2 can be locked and fixed by the thread.
In order to further improve the locking effect of the bolt 130 on the first and second insertion bodies 1 and 2, the cross section of the positioning notch 104 is set to exceed half of the first pin body 101, so that the area of the threaded portion in the positioning hole 200 can be increased, thereby improving the nail-holding power.
